Description

DESCRIPTION OF THE INVENTION: A DEVICE FOR THE COLLECTION OF FLOATING OBJECTS IN THE SEA

AREA OF TECHNOLOGY THAT RELATES TO THE INVENTION

The invention relates to equipment and devices used to collect floating objects in the sea, lake or other waters where there is a change of height level usually due to tidal and oscillation changes.

TECHNICAL PROBLEM

The inventor, as a hobby, is concerned with nature conservation, and reading various literature and reports has come to the knowledge that there is large pollution of the sea, primarily with plastic, which is a global problem. Namely, once the plastic reaches the sea, it stays in it for a long time, given the long disintegration period for plastics which is approximately 400 years, or according to some expert estimates even more than 1000 years.

According to the available data, over 300 million tons of plastic products (bags, bottles, caps, cups, etc.) are used annually. Statistical surveys published at

http://www.plasticoceans.org/ show that half of that amount of plastic is used only once and for less than 12 minutes, while 8 million tons of plastic per year end in the seas and oceans and lead to plastic marine waste. Plastic waste that ends in the sea is carried by sea currents that shed this plastic on smaller pieces so that there are already places where the concentration of plastic particles is higher than the concentration of plankton. An even bigger problem is that the plastic dropped into the sea contains different toxins which further burden the marine ecosystem. That's why plastic waste has to be removed from the sea as soon as possible.

Given the fact that the inventor also often resides on the coast of the Adriatic Sea, he was personally able to see and be assured, regardless of the season, that there was a large amount of floating plastic waste in the sea. The fact that pollution has been growing steadily with plastic waste has led him to contemplate of constructing a device that could take and retrieve floating objects without the use of special external power in the sea, with the goal of efficiently removing as much floating plastic waste as possible.

STATE OF TECHNOLOGY

The inventor has studied known devices and equipment used to collect floating plastic waste in the sea, and has determined that such devices and equipment are in fact large energy consumers. The most common equipment used for cleaning seas and marinas from floating plastic are ships equipped with special floating nets, which is an expensive solution and demands human labor. Furthermore, mini vacuum cleaners operating on the suction principle use their own power-operated pump that sucks the surrounding water surface and are extremely inefficient in terms of energy due to the fact that they need an external source of energy. The inventor is unaware of the existence of a device that would collect floating waste in the sea, based on the use of pure ecological energy due to tidal and oscillation changes.

A SHORT CONTENT OF THE CORE OF THE INVENTION

The main advantages of this invention, according to the current state of art, are that it is a simple ecological device and that it is an effective ecological device that is long- lasting and multifunctional.

Each individual device as a whole, which is the subject of this invention, functions in a very simple principle, utilizing the horizontal and vertical natural forces. Horizontally, waves generated naturally and waves caused by the influence of vessels that have the task of inserting the floating plastic objects into the device. Vertical forces are tidal changes that have a function of capturing floating plastic objects in the ecological device during low tides. By the action of waves and during high tides, the floating objects will drift into the device that needs to be placed in a position that is exposed to stronger strikes of waves. When the floating objects enter the device (the waves will "insert" the floating objects into the unit), the shutter assembly prevents the floating objects out of the unit. During low tides, the objects fall down with the water level below the lower part of the shutter assembly. During high tides the lower element of the shutter assembly is lifted and the floating objects remain trapped beneath the lower element of the shutter assembly. This prevents the floating objects from getting out of the device and thus polluting the environment again.

The key part of this ecological device is a shutter unit that serves to hold / deposit floating items within the ecological device itself. In the present invention, various embodiments of the shutter assembly may be used, for which tests have so far shown that in actual conditions they achieve satisfactory results of removing plastic floating waste from the sea and the lake, and what is common to all shutter assembly types is simplicity - they work exclusively with the help of natural force.

This ecological device for collecting floating objects in the sea has the form of a hollow body in which the sea enters and exits freely. Said hollow body has the upper part, the lower part, the rear part, and the front part, in which the front part is provided with an opening for the entry of floating plastic items. The inlet port for entry is positioned so that it is in the tidal level line and is facing the sea. As an essential part of this ecological device, the shutter assembly is secured to the inlet port so that using the tidal changes the shutter can open and close the inlet opening so that floating items can enter it, and once the floating objects enter this device they can no longer exit it unless it is mechanically removed from the device itself. Furthermore, this device at the entrance opening for the lower part of the inlet opening has a catch of the shutter assembly around which the shutter assembly can freely rotate in a direction that determines the movement of the sea level due to high and low tides changing. In one embodiment, the shutter assembly comprises the lower shutter assembly element and the upper shutter assembly element, which are mutually connected at 90 ° angle, so that the shutter location is located at the position of the shutter assembly and so that the upper shutter assembly element is not longer than half the height of the entry and wherein the lower element of the shutter is between 25% and 35% longer than the depth of the hollow body, wherein the shutter assembly is so attached to the catch of the shutter assembly that it can move from the initial position in which the lower element of the shutter assembly touches the interior of the front part the position of the shutter assembly occupies when the low tides is in its end position where the shutter assembly is in its highest position, and the achievement of which position is determined by the point of contact of the upper element of the shutter assembly and the interior of the hindquarters in the hollow body.

The closure assembly in one embodiment also comprises a flap suspended in the upper part of the inlet opening so that it can freely rotate around it up to a point of 30 ° which make a flap and an imaginary line in the direction vertical to the sea level, where the flap length is less from the height of the light entrance door, but not shorter than 60% of the height of the light entrance door, and is always located in the interior of the hollow body and is thus dimensioned in relation to the upper element of the shutter assembly that the same may pass whenever it moves due to the application of sea level below or on the outside of the flap.

In another embodiment there is a lower closure member element attached to the hollow body at the position of the shutter assembly, wherein the lower element shutter is between 25% and 35% longer than the depth of the hollow body, whereby the shutter assembly is so fastened to the catch of the shutter assembly that it is able to move from the initial position in which the lower element of the shutter assembly contacts the inner part of the front which the position of the shutter assembly occupies when it reaches the final position of the low tide in which the shutter assembly is in its highest position and the achievement of which position is determined by a point contacting the upper part of the closure assembly and the interior of the rear part of the hollow body, the closure of the assembly further comprising a flap which is curved in the upper part of the inlet port so that it can move freely around it to a maximum of 30 ° which makes the flap and the imaginary line in the direction vertical to the sea level, where the flap is less than the height of the light entrance opening, but not less than 60% of the height of the light entrance opening, and is always located in the interior of the hollow body. In one embodiment it is possible that the shutter assembly may move in the direction of the sea level change so that the movement changes the dimension of the inlet port. In further embodiments, it is possible to perform a driving device in the lower front, whereby the closure of the assembly due to sea level changes along with sea level changes can be performed, with the shutter assembly comprising a guide, receiver of the lower element of the shutter assembly, the lower element of the shutter assembly and the locks being assembled in their entirety so that the guide is guided through the guiding device due to the change of sea level, whereby the upper part of the guide assembly secures the lower closure element of the assembly by means of the lower element of the closure assembly so that it can move from the initial position in which the lower closure member of the assembly is touched by the inner part of the front part which is the position the lower element of the shutter assembly has during low tides, to its final position in which the lower element of the shutter assembly is in its highest position and the achievement of which position is determined by the contact point of the lower element of the shutter assembly and the inner part of the rear element in the hollow body.

In another embodiment, an element for the elevation of the lower element of the shutter assembly is embedded at the end of the lower element of the shutter assembly, and it is so dimensioned that the lower shutter assembly element can float in the sea. At the end of the upper element of the shutter assembly in the next embodiment, there is an element for elevation of the upper element of the shutter assembly which is so dimensioned that the upper element of the shutter assembly can float in the sea. At the end of the flap which the end of the flap can move freely in the next embodiment, there is an embedded elevation element of the upper flap which is so dimensioned that the flap can float in the sea.

In order for the water to be easily emitted from the body of the ecological device during lower levels of the sea or the lake, the subject device in the lower part has water outlet holes, dimensioned so that plastic objects cannot pass through them. In some embodiments, the hollow body is constructed as a quadrant with the front part concave to make it easier for floating objects to enter into an device. For the easiest emptying of an ecological device, the top part contains a cover and can also include an extension for mounting to be fixed to the concrete shore. Usually, in the hollow body itself is a box that accumulates plastic waste, and that box can be pulled out and put back into the hollow body. The box comprises a floor covering through which the box is removed from the hollow body and empty floating plastic waste from the device, with the box having a receptacle that can be pulled out and re-inserted into the hollow body. The floor is usually perforated so that any excess water can drain from the hollow body and then only plastic objects remain in the box. One of the possible embodiments for the quickest leakage of water from the ecological device at a time when the water level is reduced is such that the device in the lower part of the front part has an outlet for water outlet.

In the standard embodiment, the lower element of the shutter assembly comprises longitudinal slots dimensioned to permit water passage from one side to the other side of the lower element of the shutter assembly, but do not allow passage of floating plastic waste. Instead of longitudinal slits, perforations can be performed as the same effects are achieved.

The float-collecting system in the sea contains at least two ecological devices described above, which are built in a row on the concrete shore. The best effects of collecting floating waste are achieved in such systems with routers that direct floating plastic waste into ecological devices whereby the ecological devices are separated or placed between the routers.

An essential feature is that the system can be carried out in two variants and depending on the variant the system is embedded in a specially designed device exhibited in the present invention.

Variants of embodiments:

1. NEW INSTALLATION in the coastal wall. Suitable for new or coastal walls that are being refurbished.

2. FEATURED INSTALLATION on the coastal wall. Suitable for already built coastal walls.

The system is suitable for installation on the coastal walls of the sea, lakes and rivers that have the characteristics of a greater presence of boats, people and therefore the higher concentration of floating objects.

The top element of the shutter assembly has the function to prevent floating objects entering this unit from being able to float away from it. The bottom shutter assembly function has the function of preventing floating objects from leaving the device - once they are at the base of the hollow body due to high tide lifting. In addition, such protection is achieved by installing a stopper between the lower element of the shutter assembly and the front panel, so that when lowering the lower element of the shutter assembly during low tide it is impossible for the shutter assembly and the front part of the shutter assembly to connect; the stopper has the function of maintaining a permanent distance between the lower element of the shutter assembly and the front opening, so that the approximate angle between these surfaces is about 30 °.

The shutter assembly can be made so that depending on the tides it changes its position and floats on the water. Thus, in one embodiment, the shutter assembly may be made with a movable assembly, and in some other embodiment it may be provided with a fixed assembly.

In the standard embodiment, the shutter assembly has two parts, the upper shorter part serving to hold the floating objects in the upper inner part of the apparatus during high tide period and the longer lower part serves to hold the object after a period of low tide causes the objects to fall to the bottom of the hollow body so that they cannot float out of the ecological device when the high tide comes again.

The square-shaped device with two side openings (for angle outer mounting) due to its specificity requires a more complex design of the shutter assembly. In such an application, the shutter assembly should be constructed in the form of symmetrical triangles secured with one side edge (with an opening) to the side wall side. During the high tide they close the appliance completely while during low tide they open in the middle of the appliance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF AT LEAST ONE OF THE INVENTION EMBODIMENTS

Usually, this device for collecting floating objects in the sea 1 is made of iron which is then protected by galvanizing so that such a structure can be maintained under the influence of salt water.

The hollow body 5 is made in the form of a square cage with iron L profiling which is later galvanized. The shutter assembly 200 is made of plastic that floats in the sea. In another embodiment, the shutter assembly 200 is made of galvanized iron, with the elevation elements 212, 232, 252 are made of hollow plastic pieces to achieve that the closure assembly 200 floats in the sea. The cover 260 is a conventional cast iron cover in case of new installation of the ecological device 1 in the coastal wall 600.

The possible installations of the ecological device is: linear straight line, linear straight line with routers, linear curve, linear curve waveforms, angular external and angular . internal. If the case that this equipment is installed on an existing coastal wall (shore, harbor, etc.), ie if it is subsequently installed, then it is installed linear, linear with routers or angular. How the systems with built-in ecological devices 1 look, it is apparent from Figures 6 through 15. The subsequent installation is very simple - with screws, the device attaches to the upper side of the coastal wall.

If this ecological device is installed in a new concrete shore that is under construction, then it is best to include the installation of these ecological devices during the design phase of the coast.

In the embodiment when the device 1 is embedded in the coastal wall 600, for lower performance costs, only the hollow body 5 can be defined by concrete or stone to be incorporated. For the subsequent installation of the ecological device 1, stainless steel showed good characteristics and UV stabile plastic that is resistant to seawater. In the case of subsequent installation, the cover 260 should be lighter so that it does not burden the entire structure unnecessarily and is made of stainless steel sheet or UV stabile plastics.

The box 280 is made of stainless steel or plastic. It is performed so that it can be lifted from the hollow body manually or by a crane, so that at the bottom there is a floor that can be removed so that the contents can be transferred into the cargo area of the plastic waste collection vehicle. The box has an inlet opening 240 at which the lower part of the inlet port is mounted to the shutter assembly 200 and this is best with hinges whereby the shutter assembly 200 can rotate around the front part 105.

For the purpose of better routing of plastic floating waste, between embedded ecological devices 1, rubber routing guides 400 are added as shown in FIG. 7, the diameter corresponding to the distance between two ecological devices 1. Routers 400 may be derived from INOX in some other embodiment.

Depending on the amount of plastic waste and the pollution of a particular area of the sea or lake, the process of emptying an ecological device can also take place daily and you need to empty the inner box so that it is pulled out and all the contents of the waste bin into the garbage truck.

The useful volume of the inner container for floating objects can be different or it can be adapted to the situation. In areas with larger water contamination, devices with the capacity of one cubic meters can be installed, so there is no need for daily emptying of the box. This device also features a lid that also serves as a revision window to track the level of internal body coverage. Emptying of the inner box is a very simple process that can be manually carried out (for devices with less than one cubic meter capacity) or with a special crane truck (for devices with capacity larger than one cubic meter). When accessing the emptying, the top cover is removed and the crane hook or hand grip is attached on the inner box and gently pulled out of the unit. As the bottom of the box is perforated, all the liquid will drain and only the garbage will be remain in the inside of the body. Once the inner body is pulled out and placed above the tank in which the garbage is planned to be transferred, the perforated base is removed and the deposited plastic items are discharged into the waste disposal tank. Subsequently, the base is returned to its position and the inner body - box is placed back in the device. When the internal body is put back into the device, the lid is returned and the device is ready to use.
