Description

Aquaculture system with lighting device

Technical Field

The invention relates to the technical field of cultivation illumination, in particular to an aquaculture system with an illumination device.

Background

In the evolution process of hundreds of millions of years, aquatic animals form a unique visual physiological structure based on environmental characteristics, for example, fish receives optical signals through retina and pine cone photoreceptors so as to synchronously sense and adapt to the optical environment of natural habitat. Therefore, the light environment characteristics of aquatic animals in the nature are the primary reference factors for optimizing and regulating the light environment factors under the artificial culture conditions. When the density of algae in the pond is too high and the midday light intensity is high, the photosynthesis of the algae makes the content of dissolved oxygen in the pond very high, but when the light intensity is weak, the respiration of organisms in the pond consumes a large amount of dissolved oxygen, so that the dissolved oxygen in the pond is drastically reduced. When the pond is no longer suitable for algae growth, a large number of algae die at the same time, thereby generating a large amount of organic corrosive substances at the bottom of the pond, and the decomposition of the organic substances requires a large amount of dissolved oxygen and generates toxic gases. Toxic substances generated by algae death can cause fish death, and thus, light can indirectly affect the dissolved oxygen level of the pond through aquatic plants. Boeuf G, however, mentions in Does LIGHT HAVE AN influence on fish growth that, although during the transmission of light in water, strong attenuation of light in water occurs due to complex absorption processes of animals and plants and scattering processes of different media. However, most aquatic organisms except species inhabiting in holes and deep sea have complex visual physiological structures, and few species can survive without light. Therefore, the dark or high-intensity illumination of the cultivation workshop is not preferable all the day.

The fish and shrimp are extremely sensitive to light, and the eyes are used as main light sensing organs of the fish and shrimp, and show characteristics which change according to different growth stages. Newly hatched fish and shrimp typically have transparent eyes. However, as growth progresses, the retina will develop and perfected gradually, the time required for this process varying from species to species. In aquaculture, the ideal transparency of the pond should be controlled between 20 and 40 cm, because if the water is too clear, light can easily penetrate to the bottom of the pond, thereby promoting the growth of harmful microorganisms and possibly the generation of toxic gases. The intensity of illumination has obvious influence on the body color of fish and shrimp fries in the growth process, and the lack of illumination can cause abnormal growth. In some fish, their visual organs may decline over time, while other senses are enhanced. Studies have shown that for young fish of the european tongue bass (Dicentrarchus labrax), the higher the light exposure, the higher the survival rate.

Gu Husen et al in the progress of light inhibition research on photosynthesis of higher plants mention that light irradiation affects nitrogen absorption by a bacteria-algae combined system by directly affecting photosynthesis of algae. Algae are an important component of a bacteria-algae combination system, and algae are photoautotrophic organisms that are capable of converting absorbed light energy into chemical energy for their own growth. In general, algae photosynthesis increases with increasing light intensity. Markou G et al, microalgal and cyanobacterial cultivation: the supply of nutrients, indicates that once the photosaturation point is exceeded, a photoinhibition effect is generated on algae, and strong light can generate photooxidative stress, damage proteins and pigments in the photosynthetic system of algae, inhibit the growth of algae, and even cause algae death. Nitrogen is an essential element for algae growth, light can directly influence the absorption of nitrogen by algae by affecting its photosynthesis, and algae produce oxygen for respiratory metabolism of bacteria by photosynthesis, so light has an indirect influence on the absorption of nitrogen by bacteria. Xu et al studied the effect of light intensity on dunaliella salina growth and photosynthesis in "The influence of photoperiod and light intensity on the growth and photosynthesis of Dunaliella salina(chlorophyta)CCAP 19/30". In the range of 50-1500 mu mol.m ^-2·s^-1, along with the increase of the light intensity, the contents of chlorophyll and carotenoid are reduced, the cells are subjected to larger and larger light stress, and photosynthesis is inhibited. Liangyu et al found in the study of SBR treatment simulated domestic sewage study based on the algae symbiotic system that compared with strong illumination (183.5 mu mol.m ^-2·s^-1), the algae symbiotic system has remarkable advantages in the removal effect of ammonia nitrogen and total nitrogen in sewage under the condition of low illumination intensity (92.27 mu mol.m ^-2·s^-1).

The input of a large amount of nitrogen salts is easy to cause eutrophication of the shrimp culture water body in aquaculture, and is one of main reasons for preventing the sustainable development of shrimp culture health. Therefore, how to effectively treat excessive nitrogen salts in the culture water body to maintain a healthy water quality environment has become a main subject to be overcome by the shrimp culture industry. Microalgae and bacteria are important components in the prawn culture ecological system, and play an important role in maintaining the dynamic balance of the culture ecological system, accelerating the material circulation and purifying the culture water quality. On one hand, as a main body for energy and substance conversion, bacteria and microalgae can effectively absorb and utilize excessive dissolved nitrogen in a loose pond of prawn culture, lighten the eutrophication degree of water body and play an important role in maintaining healthy water quality environment, on the other hand, carbon dioxide generated by degrading organic matters by bacteria can provide carbon sources for algae, and oxygen released by photosynthesis of algae can promote respiratory metabolism of bacteria to supplement each other.

The reflectance spectrum of a body of water is closely related to the nature and content of suspended matter. By using a spectrum radiometer, the turbidity caused by suspended sediment is measured and is one of the main factors influencing the reflectivity of the water body. In the orange and red light wave bands of visible light, the reflectivity of turbid water is about 5 percent higher than that of clear water. Clear water at 0.75 μm has a reflectivity drop to zero, while muddy water containing silt also has a higher reflectivity at 0.8 μm in the near infrared band. The turbid water reflectance drops to zero at 0.95 μm. The reflectivity results of the terrestrial satellite measurement also show that a linear relationship exists between the reflectivity of the wave band of 0.6-0.7 μm and the turbidity of the water body.

The chlorophyll concentration in the water body has a remarkable influence on the spectral characteristics of the water. The chlorophyll concentration of the water body is increased, the reflectivity of the blue light wave band is obviously reduced, and the reflectivity of the green light wave band is obviously increased. Chlorophyll concentration is an important indicator for measuring primary productivity and high nutrition of water. Thus, the presence and concentration of algae can be monitored remotely. Impurities in natural water, besides suspended inorganic substances and chlorophyll, other substances can also cause the change of the spectral characteristics of the water. For example, water spilled oil contamination increases the reflectivity in the ultraviolet and blue bands. The content of acid or inorganic salt in the water body has small influence on the reflectivity of the water, and no difference is seen. In summary, the water body has different spectral characteristics due to different turbidity, chlorophyll or water surface properties.

Under the background of industry development, along with the gradual upgrading and perfecting of emerging technologies such as artificial plant factories, artificial culture environments, intelligent culture and the like, the aquaculture industry also needs intelligent and mechanical upgrading. Based on aquaculture, there is actually a lighting requirement for the aquaculture object, such as aquatic plants, fishes and other species, and the existing aquaculture technology is generally simpler, namely, one aquaculture system or method is designed for one type of aquaculture, but aquaculture systems based on joint culture of multiple species at various levels in a water environment are less visible, especially the design of schemes of mutual utilization, substance transfer and the like of substances (such as nutrients, oxygen, temperature, pressure environments and the like) required for growth and substances generated by growth (such as excrement, water-soluble oxygen generated by photosynthesis and the like) of the multi-species aquaculture object at different levels is less common, so that the problem that the aquaculture object is single, and better substance and energy transfer and utilization cannot be realized is caused.

The prior art CN113516635A provides a fish and vegetable symbiotic system and a vegetable nitrogen element demand estimation method based on fish behaviors. The fish and vegetable symbiotic system comprises a vegetable planting pool, a fish raising pool, a water pump, a camera, a filter and a computer. The estimating method comprises the following steps of 1, establishing a fish-vegetable symbiotic system, 2, analyzing and counting fish behavior data, 3, establishing a model relation between fish liveness and nitrogen element concentration, and 4, inputting a test set into a trained optimal model to obtain a predicted value of nitrogen element content in water. The device comprehensively calculates fish behavior data by adopting a mode of combining machine vision and mathematical model analysis, can reflect the activity degree of fish under the condition of different nitrogen element concentrations, and links fish behavior with plant nutrition degree, but light is used as a key factor for influencing plant nutrition absorption, and a light source is required to irradiate a fish pond, algae in the fish pond can also influence the activity degree of fish, and the device ignores the influence of a bacteria-algae symbiotic system in a water body on fish when calculating the demand of nitrogen element based on the device, so that the device is not applicable to aquaculture of traditional farmers.

Furthermore, since the inventors herein have studied numerous documents and patents, on the one hand, and have not set forth in detail all the details and content of the invention for the purpose of understanding the differences to those skilled in the art, on the other hand, the invention is by no means lacking in the features of the prior art, but rather the invention has all the features of the prior art, and the applicant retains the right of the prior art in the background of this invention.

The prior art has developed technical solutions for integrated cultivation of different organisms. For example, CN106719244a discloses an automatic integrated plant algae, zooplankton and fish cultivation device, which uses a microfiltration membrane to separate zooplankton, plant algae and fish for integrated cultivation, not only can avoid the unbalanced food chain problem in mixed cultivation, but also is convenient to take, and simultaneously, oxygen and carbon dioxide can realize intercommunication so as to meet the living conditions required by internal animals and plants, and uses a magnetizer to convert macromolecular water into small molecular water, so that the permeation of water molecules into the microfiltration membrane can be quickened, the survival rate and quality of animals and plants are improved due to the high content of dissolved oxygen in the magnetized water, and the excrement of zooplankton and fish is collected and fermented to form a cycle as fertilizer of plant algae, so that the single fermentation can avoid polluting water and is also beneficial to the absorption and utilization of plant algae. However, the illumination lamp arranged at the fixed position in the technical scheme provides illumination for plant algae for a specific time period every day, and does not relate to the technical content of adjusting parameters such as the position, the intensity, the period and the like of the illumination according to growth differences among different organisms.

In order to overcome the defects of the prior art, the application provides an aquaculture system with a lighting device, which comprises a first aquaculture unit, a second aquaculture unit and a third aquaculture unit.

The light wavelength range of the number of light emitting components is selected according to a first organism in the first cultivation unit, a second organism in the second cultivation unit and/or a third organism in the third cultivation unit to be affected, and the light period of the number of light emitting components corresponds to the illumination time period of the first organism, the second organism and/or the third organism.

According to a preferred embodiment, the aquaculture water flows through the first aquaculture unit, the second aquaculture unit and the third aquaculture unit in sequence, and the aquaculture water flowing out of the third aquaculture unit is returned to the first aquaculture unit.

Unlike the prior art, the present invention is capable of adjusting illumination parameters of an illumination unit according to biological growth conditions within different farming units to produce time-dependent illumination with different wavelength bands at different depth locations within the different farming units. Based on the above-mentioned distinguishing technical features, the problems to be solved by the invention can include how to control the propagation and growth speed of algae by controlling parameters such as the illumination time, the intensity and/or the depth in water of the illumination unit, and further control the amount of algae available to animals at different depths and positions so as to promote the growth of the animals. Specifically, on the one hand, according to the scheme, by configuring different cultivation areas, aquatic products at different positions in the water body are placed in different cultivation units to be cultivated, and the water body can move in at least two cultivation units so as to drive living demands or living excreta of cultivated aquatic products in at least part of different cultivation unit environments to move between the cultivation units, so that utilization of substances in the aquaculture environment is realized, construction of an internal balance ecological environment is facilitated, cultivation cost is obviously reduced, and cultivation efficiency is improved. On the other hand, the invention can adjust the setting parameters of the lighting units according to the difference of biological growth states in different cultivation units, so that the growth among different organisms can be mutually promoted, and the cultivation efficiency is maximized.

According to a preferred embodiment, the lighting unit comprises a light-transmissive container and a light-emitting component arranged in the light-transmissive container, the light-transmissive container being configured to separate the liquid from the light-emitting component, wherein the light-transmissive container and the light-emitting component are filled with a filling liquid, the lighting unit being data-connected to the control unit.

According to a preferred embodiment, the first cultivation element for cultivating the first organism and/or the second cultivation element for cultivating the second organism is provided with a cultivation substrate, preferably a sand layer and/or a sand layer.

According to a preferred embodiment, the second culturing member for culturing the second living being includes a water supply and drainage member capable of changing a water level by water supply and drainage, thereby simulating ebb and flow in the second culturing member.

According to a preferred embodiment, the second cultivation unit for cultivating the second organism is connected to the first cultivation unit in a first separation unit for cultivation water.

According to a preferred embodiment, the second cultivation unit and the first cultivation unit, in which the second organism is cultivated, are connected by a feeding unit for feeding the first organism. The third culturing unit is integrated in the feeding unit.

According to a preferred embodiment, the second cultivation unit for cultivating the second organism is connected via a first connection channel for cultivation water to a second separation unit for separating the dissolved faeces of the first organism.

According to a preferred embodiment, the second separation unit is integrated in the first separation unit of the aquaculture water.

According to a preferred embodiment, the second separation unit comprises at least one fourth cultivation unit, wherein the fourth cultivation unit is filled with cultivation water and cultivated with a fourth organism.

According to a preferred embodiment, the fourth cultivation unit for cultivating the fourth organism has a water supply and drainage unit for changing the water level in the fourth cultivation unit.

According to a preferred embodiment, the light emitting assembly at least partially occupies the interior volume of the light transmitting container such that there is room for the light emitting assembly around within the light transmitting container. In the case of a gas or filled part of a liquid in the interior space of the light transmitting container, the density of the lighting unit can be controlled to be less than or equal to the density of the body of water in the aquaculture environment in which it is located, so that the lighting unit can operate in a manner floating on or in the water surface.

According to a preferred embodiment, the lighting assembly is configured to emit full spectrum light or to simulate daylight. The interior space of the light-transmitting container is filled with a filling liquid, the filling liquid is configured to filter light emitted by the light-emitting component into a water grass growth regulation spectrum, and the filling liquid is configured to gather on the upper layer of the water body. The filler liquid may conduct heat generated in the light emitting assembly into the lighting unit and thus onto the algal culture body.

According to a preferred embodiment, the control unit is further configured to control the size and position of the light emitting assembly and/or to adjust the addition and position of the filling liquid such that at least part of the light emitted by the light emitting assembly is transmitted through the filling liquid of the light transmitting container to enter the body of water. The device can provide a certain full spectrum light which is required by fish growth and imitates sunlight, and regulate and control the biological clock of the fish, so that the living habit of partial fish can be properly regulated, and better culture effect can be achieved in certain aspects.

According to a preferred embodiment, the control unit is further configured such that the light transmitted through the filling liquid is able to impinge on the first living being, the second living being and/or the third living being in its corresponding depth level of the body of water in a manner different from at least one light parameter of the light not transmitted through the filling liquid, the first living being, the second living being and/or the third living being at least different from another living being in another level receiving light radiation not transmitted through the filling liquid.

Unlike the prior art, the control unit of the present invention is capable of changing the illumination parameters of illuminating organisms in different water depth levels by means of the light emitting assemblies in the lighting unit. Based on the above-mentioned distinguishing technical features, the invention can solve the problems by adjusting the size and position of the filling liquid and/or the light-emitting component, so that the light-emitting component can generate different illumination for different layers of aquatic products at the same time, thereby improving the cultivation efficiency of the different layers of aquatic products. For example, the filling liquid is deposited at the bottom of the light-transmitting container of the light-emitting component under the action of the basic gravity, so that the light transmitted by the filling liquid only mainly irradiates the bottom surface of the water body, and the aquatic product at the bottom surface can be selected as aquatic weed. Due to the influence of gravity, the light emitted by the part of the light emitting assembly which is not blocked by the filling liquid can only and mainly irradiate the middle or top layer of the water body, and the aquatic products of the middle or top layer can select fish for example. In the above exemplified configuration mode, fish live in the middle and upper layers of the water body, and aquatic weeds grow in the sand layer positions of the bottom layer, so that by reasonably configuring the size and positions of the filling liquid and/or the light emitting components, the light emitting components can generate differential illumination for different layers of aquatic products at the same time, and on the basis of the structural configuration of the lighting unit which maintains the position of the lighting unit in the water body by utilizing buoyancy, the height of the lighting unit can be automatically adjusted based on the depth change of the water body, so that under any water surface height, the light rays emitted by the lighting unit always move along with the height change of each layer of the water body.

According to a preferred embodiment, the lighting unit is capable of causing a change in position of itself and/or of the filling liquid therein and/or of the light emitting assembly therein in the longitudinal direction based on the tidal action such that the filling liquid within the lighting unit and the light emitting assembly are moved in relation to each other, thereby producing illumination of the adapted light for several levels in the body of water at least within the nodes of the tidal action. For example, under the condition that fish and aquatic products exist in a water body at the same time, by configuring the relative position relation between filling liquid in the lighting unit and the light-emitting component, at a tide rising node, the first position relation exists between the light-emitting component and the filling liquid, and at a tide falling node, the second position relation exists between the light-emitting component and the filling liquid based on the change of water level, so that light transmitted by the filling liquid and light not transmitted by the filling liquid can change in different nodes, and then the aquatic products and the fish can receive different illumination in different nodes.

According to the scheme, the automatic change and corresponding illumination can be automatically realized according to different growth requirements of aquatic products on different water body layers in different periods based on tidal action, and the driving process does not need to use an additional driving structure, stage detection equipment or a complex integral structure and the like, so that the automatic illumination regulation and control along with the change can be realized only by means of the water body state change caused by the simple tidal action.

According to a preferred embodiment, the lighting unit maintains its position in the body of water at least with buoyancy and is capable of adjusting the height of the lighting unit based on the depth variations of the body of water, such that the light emitted by the lighting unit at any water level is moved based on the layer height variations of the body of water. Under the action of tides, the luminous component in the lighting unit can move up and down in the space in the pipe along with the fluctuation of the water level of the external water body, and relatively, the filling liquid in the interlayer of the pipe wall is fixed in relative position due to no contact with the outside, so that the luminous component can move relative to the filling liquid by the action of tides.

The third culturing member 400 is for providing nutrients to the algae and light for photosynthesis. The third culturing member 400 is configured to have a lighting unit 1200 filled with water and ventilated, the lighting unit 1200 having a light emitting assembly. The third culturing member 400 has a vent and an air outlet.

The third culturing member 400 comprises a controllable light emitting element. The lighting unit 1200 has a light-transmissive container with controllable light emitting assemblies disposed therein. The light-transmitting container is, for example, constructed as a glass tube. The lighting assembly may have one or more LED assemblies, in particular LED circuit boards, arranged along the light-transmitting container and illuminating the algae. The lighting unit 1200 may have a filling liquid on a free end of a lower portion of the light-transmitting container. The filling liquid may conduct heat generated in the light emitting assembly into the lighting unit 1200 and thus onto the algal culture. For this purpose, the cooling body is connected to the light-emitting module and is flushed on the outside by the algae culture body.

The lighting unit 1200 is connected to the container cover at the upper end of the light-transmitting container and protrudes one piece from the container cover. A control unit may be connected to the lighting unit 1200 on the outside. Thereby, energy input towards the light emitting assembly can also be achieved. Furthermore, an overpressure valve may be provided on the outside of the lighting unit 1200, which overpressure valve is connected to the tube interior. The light-transmitting container is sealed with respect to the filling liquid and the cover.

The lighting unit 1200 may also be provided with sensing means, such as temperature sensors, in suitable locations for detecting and monitoring algae growth and/or environmental conditions. The algal culture may be temperature-regulated by the control unit in the third cultivation unit 400. In this case, waste heat of the light-emitting component can be used on the one hand, and possibly auxiliary heating or cooling devices can be used on the other hand. The lighting unit 1200 has different, individually controllable light emitting assemblies such that the lighting unit 1200 can produce light having different wavelength bands at different locations thereof, e.g., lamps located at different depths can produce different spectral bands, lamps located at different locations can produce different spectral bands depending on the time of day, time of year, or the natural light of the environment reaching a particular depth of the pond. The color of the lamps in the light-transmitting container is selected according to the species of fish or shellfish to be affected. The different colors of the lamps affect the growth of different algae or aquatic animals. Algae and the like also require a period of darkness, and individual plants each have optimal light and darkness durations or periods. The present application uses a light duration control of the control unit, which time period can be predetermined and controls the individual light emitting assemblies to adjust the light periods of the light emitting assemblies accordingly. The present application is therefore based on the pre-determined presence of an algae type (third organism) and its response to different illumination parameters by adjusting the light parameters of the lighting assembly to create an environment that meets the illumination parameters required for the algae type to maximize algae production. In addition to aquaculture applications, this manner of illumination adjustment may be used in other applications to promote algae growth and/or nitrogen/CO ₂ removal or consumption.

Preferably, the present application also provides an assembly and method for improving the growth of algae-fed animals. Since algae require light/nitrogen to grow, in order to improve aquatic animal growth, the present application controls the reproductive growth of algae by illumination time, intensity, and/or depth in the water, thereby controlling the amount of algae available to the aquatic animal at different depths and locations to promote aquatic animal growth. Due to the feature of filling the light-transmitting container or capsule with a type of filling liquid, such as mineral oil, a plurality of light emitting assemblies may be placed in a heavy glass tube or other light-transmitting container and function effectively. In particular, the dielectric oil transfers heat from the LED devices and drivers (or other circuitry) to the glass and then to the body of water. The combination of glass and oil allows the light sources to be cooled in the surrounding water, thus enabling the light sources to operate at higher light output (or at higher power levels) and preventing the circuit from overheating than if they were other types of lamps or if the tube were filled with air.

Preferably, the above-described lighting assembly adapted for aquaculture is further adapted to perform additional light supplementing in addition to natural light in an environment where tidal influences are present. For example, in an aquaculture area where the typical environment of use is the seaside or lake side, such areas of adjacent waters typically present defined aquaculture areas, such as farmed seaweed, pasture, crayfish, snails or crabs, and the water bank where a body of water of greater overall mass is present is typically subjected to a relatively significant tidal action, thus causing it to experience a relatively significant tidal event over a relatively well-defined period of time. Basically, the water depth near the shore will exhibit periodic fluctuations over different time periods. Generally, the water depth is higher at the time of tide rise and lower at the time of tide fall. In another embodiment, although the breeding site is not selected to be at sea or in a large lake, it is possible for the breeder to choose to apply tidal action in the aquaculture area in a manner that is artificial, such as by using timed water absorption and water supply to simulate the rising and falling tides, in order to simulate the natural environment of the area to ensure that the associated water is able to enjoy a more primitive growth environment.

The present inventors have found that in aquaculture, the water is often complex from the surface to the bottom, there are one or more biological species in each level of the water, and each biological species, whether or not the target object of the aquaculture, together form a small-scale ecosystem of the aquaculture environment, whereas for aquaculture lighting, the prior art is often configured more simply, i.e. a one-lamp configuration, such as for example, where fish-farming lighting is present, where aquatic-grass lighting is present, whereas the prior art rarely sees a solution that can vary the lighting to cope with organisms in one or more aquaculture environments based on aquaculture environments, especially where tidal action is present, with tidal action. For example, there is often a certain distribution law of aquatic products in the depth direction of water, for example, in a cultivation environment containing aquatic weeds and fish, the aquatic weeds usually grow at the bottom of the water, and the fish have flexibility of space movement. According to research, light has an influence on fish body pigment, and in the cultivation industry of certain ornamental fish, certain specific spectrum light induction is required to be provided when the ornamental fish grows so as to obtain the finished ornamental fish with full color, and meanwhile, some aquaculture personnel can cultivate various valuable commodities by utilizing an aquaculture field, for example, plants such as aquatic plants, seaweed and the like are cultivated by utilizing the bottom space of a water body while the fishes are cultivated, and the plants also need intervention of illumination for growth.

According to a preferred embodiment, a lighting unit 1200 is provided, the lighting unit 1200 having a light transmissive container with a controllable light emitting assembly disposed therein. The light-transmitting container is, for example, constructed as a glass tube. The light emitting assembly may have one or more LED assemblies, in particular LED circuit boards, extending along the light transmissive container. In one embodiment, the lighting assembly does not fully occupy the entire internal volume of the light-transmissive vessel, such that there is still room around the lighting assembly within the vessel, and where there is gas in the room, or a portion of the liquid is filled, the density of the lighting unit 1200 as a whole may be controlled to be less than or equal to the density of the body of water in the aquaculture environment in which it is located, to enable the lighting unit 1200 to operate in a manner that floats on or in the water. The lighting unit 1200 may have a filling liquid at a suitable location, for example on the free end of the lower part of the light-transmitting container. In one embodiment, by configuring the size and position of the light emitting assembly and/or adjusting the addition and position of the fill fluid, at least a majority of the light emitted by the light emitting assembly is transmitted through the fill fluid into the body of water.

In another embodiment, by configuring the size and position of the light emitting component and/or adjusting the addition amount and position of the filling liquid, part of the light emitted by the light emitting component enters the water body through the transmission of the filling liquid, and part of the light enters the water body without the transmission of the filling liquid. For example, the filling liquid is deposited at the bottom of the light-transmitting container of the light-emitting component under the action of the basic gravity, so that the light transmitted by the filling liquid only mainly irradiates the bottom surface of the water body, and the aquatic product at the bottom surface can be selected as aquatic weed. Due to the influence of gravity, the light emitted by the part of the light emitting assembly which is not blocked by the filling liquid can only and mainly irradiate the middle or top layer of the water body, and the aquatic products of the middle or top layer can select fish for example. At least one optical parameter of the light transmitted through the filling liquid is different from the light transmitted without the filling liquid, for example, in the above-mentioned aquatic product configuration mode, the optical parameter is selected to be an optical band, and the optical band required for aquatic plant growth is mainly concentrated in a blue optical band, and under this band, aquatic plant can be grown in a better growth environment. Accordingly, based on the filtering principle, the filling liquid can be configured to be blue, and the light transmitted through the filling liquid can be filtered to blue band light required for aquatic weed growth. And partial fishes grow, and a certain full spectrum light imitating sunlight is needed to regulate and control the biological clock of the partial fishes, so that the life habit of the partial fishes can be properly regulated, and a better cultivation effect can be achieved in certain aspects. In the above-exemplified configuration mode, fish live in the middle and upper layers of the water body, and aquatic weeds grow in the sand layer positions of the bottom layer, so that by reasonably configuring the size and positions of the filling liquid and/or the light emitting components, the light emitting components can generate different illumination for different layers of aquatic products at the same time, and the configuration of the lighting unit 1200 which maintains the position of the lighting unit 1200 in the water body by at least utilizing buoyancy according to the embodiment can automatically adjust the height based on the depth change of the water body, so that the light emitted by the lighting unit 1200 always moves along with the height change of each layer of the water body at any water surface height.

Still further, the lighting unit 1200 is capable of causing a change in position of itself and/or of the fill fluid therein and/or of the light emitting assemblies therein in the longitudinal direction based on tidal action such that the fill fluid and the light emitting assemblies within the lighting unit 1200 undergo relative positional movement, thereby producing illumination of the adapted light at different levels in the body of water at least within the plurality of nodes of the tidal action. Specifically, the tidal action has at least two larger nodes, namely a flood node and a flood node, the two nodes have different effects on the living aquatic products of each layer in the water body, for example, due to the fact that the flood can wash nutrient substances on the shore to an offshore area, sea fish can gather and predate on the water shore in the process of flood, the same aquatic weeds are easier to contact light to develop photosynthesis in the process of flood, the aquatic weeds usually enter respiration in the process of flood, at the moment, the aquatic weeds start to grow, and certain regulation signal light is required for regulating and controlling the growth characteristics of the aquatic weeds, for example, the color development characteristics of some ornamental aquatic weeds, and the illumination is different from the full spectrum illumination of photosynthesis, usually illumination in a single spectrum range. Therefore, according to the above embodiment of the present invention, for example, when there is fish and aquatic products in a water body, by configuring the relative positional relationship between the filling liquid and the light emitting component in the lighting unit 1200, at the tide rising node, the light emitting component and the filling liquid have a first positional relationship, and at the tide falling node, based on the variation of the water level, the light emitting component and the filling liquid have a second positional relationship, so that the light transmitted by the filling liquid and the light not transmitted by the filling liquid can vary in different nodes, and then the aquatic products and the fish receive different illumination in different nodes. A possible example is that the light-transmitting vessel of the lighting unit 1200 is provided as a long tubular structure, and the tube length is configured such that at least one end of the vessel is in contact with the bottom of the body of water and the other end extends out or is flush with the surface of the body of water. Further, the light-transmitting vessel is erected in the body of water, and its bottom may be fixed in the body of water in such a manner as to be inserted into the gravel at the bottom of the body of water, for example. The light-transmitting container is of a sandwich structure, namely, the wall of the light-transmitting container is provided with a hollow space, filling liquid is stored in the hollow space, the hollow space can be set to be a closed space or a closable space in order to avoid mixing liquid in a water body with the filling liquid, and a light-emitting component is arranged in the space in the tube of the light-transmitting container. Further, the volume of the light emitting component is smaller than the volume of the inside of the tube of the light transmitting container. Still further, the light emitting assembly is configured as a mover structure movable within the light transmissive container conduit, e.g., as a wrap-around tube section structure similar to an elevator in a construction mode of an elevator mating elevator hoistway, with light emitting light beads disposed in the tube sections, the light emitting assembly having an outer wrap to avoid light beads failing in water. Preferably, the enclosure of the lighting assembly is provided with air so that the lighting assembly is at least capable of floating in a body of water. The tube of the light-transmitting vessel is capable of entering water in the body of water, and preferably the level of the water in the tube is capable of varying with the variation of the level of the body of water outside the tube. Preferably, the two levels are approximately level. For example, the position that the printing opacity container is close to the water bottom is provided with the trompil, and the trompil passes the intermediate layer space of printing opacity container and does not communicate with the intermediate layer space for the intraductal water body can with intraductal in-connection, thereby make intraductal water that can dash in with the intraductal unanimous of outer liquid level, thereby, the luminous component of setting in the intraductal can be lifted by buoyancy. Under the action of tides, the luminous component in the pipe can move up and down in the space in the pipe along with the fluctuation of the water level of the external water body, and relatively, the filling liquid in the interlayer of the pipe wall is fixed in relative position due to no contact with the outside, so that the luminous component can move relative to the filling liquid by the action of tides. Further, the light emitting assembly is configured to emit full spectrum light or simulate sunlight, the filling liquid is configured to filter the light emitted by the light emitting assembly into a water grass growth regulation spectrum, and the filling liquid is configured to gather on the upper layer of the water body. at the rising tide node of the tide, the light-emitting component rises along with the water level of the water body, so that the light-emitting component is positioned at the upper layer of the transparent container, the light irradiated by the light-emitting component irradiates the water body in a form of filtering by the filling liquid, the filtered pipeline provides a regulation effect for the growth of the water grass due to the respiration of the rising tide node, and at the falling tide, the light-emitting component falls along with the water level, so that the light-emitting component is positioned at the lower layer of the transparent container, the light irradiated by the light-emitting component irradiates the water body in a form of not filtering by the filling liquid, the water grass is in photosynthesis, the full-spectrum illumination of the light-emitting component can provide sufficient light energy for the water grass, and particularly, at night when the falling tide, a great part of time is in, namely the external environment can not provide sufficient illumination for the water grass, and at the moment, the light-emitting component can ensure that the water grass can continuously perform photosynthesis. Furthermore, the nodes of tidal action are not limited to the flood tide nodes and the flood tide nodes, any nodes in the process, especially the stage nodes with water level maintained at a certain height for a certain period of time, can be used as a utilization object, at this time, by designing the light emitting components and/or the filling liquid along with the water level movement of the water body, different relative position relations can be formed between the two nodes, and then by designing whether the light emitting components emit light through the filling liquid or emit light through various filling liquids under each relative position relation, irradiation modes with different light parameters can be realized, for example, designing layered filling liquids, each filling liquid has different filtering effects, for example, one filling liquid filters light into blue light, one filling liquid filters light into red light, and the blue light is used for illumination of aquatic weeds, and red light is used for color development character induction of ornamental fish.

The structural configuration capable of changing the relative position of the light emitting component and the filling liquid based on the water level change of the water body can have other forms besides the above-mentioned exemplified structural forms, for example, the light emitting component can be relatively fixed, the filling liquid can be driven to move by utilizing the buoyancy of the water level of the water body, even the filling liquid can be formed by utilizing the water body itself, for example, the interlayer wall of the transparent container with the interlayer is arranged to be capable of being communicated with the water body, the interlayer space is provided with a material which can be dissolved in the water body and can change the color of the water body in advance, or a material which is insoluble in water but can be uniformly dispersed in the water body, for example, some pigments which can volatilize for a long time and powder materials with color are arranged, when the water level of the water body changes due to the tidal action, the water body enters or flows out of the interlayer wall, and meanwhile, due to the arrangement of the materials, the water body and the color materials can be combined to form a combined liquid which can replace the filling liquid, and similar filtering functions can be realized.

According to the scheme, the corresponding illumination can be automatically changed and given out according to different growth requirements of the aquatic products on different water body layers in different periods based on the tidal action, the driving process does not need to use an additional driving structure, stage detection equipment or a complex integral structure and the like, the automatic illumination regulation and control along with the change can be realized only by means of the water body state change brought by the simple tidal action, the scheme is remarkably superior to the conventional aquatic product illumination mode, the relatively higher culture effect can be achieved in the multi-level and multi-aquatic product culture mode, and particularly the aquaculture in the offshore area of the sea or the large lake is achieved, or the aquaculture scene of the environment is simulated, so that the method has excellent effects.
