Description

A controllable water layer raft culture system

technical field

The utility model relates to a controllable water layer raft culture system, which belongs to the field of aquatic product breeding equipment.

Background technique

Raft aquaculture has made an important contribution to my country's mariculture and is one of the main methods of mariculture in my country. Although the scale of raft farming in China ranks first in the world, the types of farming involve algae (kelp, seaweed, asparagus, Eucheuma, agaric, hijiki), shellfish (scallops, oysters, mussels), abalone, ginseng, etc. Sea urchins, crabs and other dozens of species, the aquaculture production accounts for more than half of the total domestic mariculture production, and the per unit yield has reached a relatively high level. However, most of China's mariculture activities are currently concentrated in the near-shore -15-meter isobath. The waters between -15 and -40m isobaths still need to be vigorously developed, but because these sea areas have strong waves and rapid currents, it is not easy to set up raft farming equipment, so it is urgent to carry out wind and wave resistance for raft farming facilities in waters with high sea conditions Technical research, expanding new aquaculture space, and meeting the major needs for the healthy and sustainable development of marine fisheries. During the "Eleventh Five-Year Plan" period, the state paid full attention to raft breeding engineering facilities and ecological breeding technology, established major project topics, and cooperated with many powerful universities and scientific research institutes in the country to tackle key problems, aiming at the ecological characteristics of sea areas. Algae are the main breeding objects. Research on raft farming engineering facility structure and layout optimization technology, anti-wind and wave technology, and large-scale ecological control technology to build an efficient raft farming engineering facility system suitable for high sea conditions.

Contents of the invention

The utility model provides a controllable water layer raft culture system. By controlling the buoyancy and sinking force and the length of the floating rope in the raft system, the lifting operation of the raft culture system is realized, and the resistance of the existing deep water raft culture facilities is solved. The problem of poor wind and wave performance and the inability to adjust the water layer arbitrarily.

A controllable water layer raft culture system, which consists of a rope (1), a string of balanced floating balls (2), an anchor rope (4), a fixed floating ball (5), a water layer regulating floating ball (6), a depth regulating Composed of rope (7), weight (8) and pile anchor (9), the rope (1) is the main rope with a length of 40m to 100m, and the breeding objects (3) are hung on the rope (1). The balance float string (2) is a series of small floats, which are connected in series by ropes with a diameter of about 8 mm, evenly tied on the rope (1), and are used to balance most of the weight of the breeding object (3), and the water layer controls the float ( 6) The depth control rope (7) is respectively tied to the two ends and the middle of the rope (1). If the rope (1) is short, it only needs to be installed at both ends, and the weight (8) is tied to each water. The layer control floating ball corresponds to the position of the rope (1), which is used to effectively realize the sinking of the rope (1). The fixed float (5) and the connecting rope (10) are arranged at the upper end of the anchor rope (4). Appropriate position, this node one end is connected with rope (1), and the other end is connected with pile anchor (9).

The utility model adopts the depth regulating rope to control the diving depth of the rope, which not only helps to improve the anti-wind and wave performance of the raft system in typhoon weather, but also can adapt to the requirements of different breeding objects on the breeding water layer. The utility model has the advantages of simple processing technology, convenient operation, long service life, convenient mass promotion, and well adapts to the demand for facility breeding to advance to the open sea.

Detailed ways

Below in conjunction with accompanying drawing, the technical solution of the utility model is described further in detail.

As shown in accompanying drawing 1 and accompanying drawing 2, a kind of raft culture system with controllable water layer, rope (1) is polyethylene rope, long 40m～100m, two ends pass anchor rope (4) and pile anchor (9 ) connected and fixed in the designated breeding sea area. The upper end of the anchor rope (4) is at a certain position away from the water surface, and is connected with the fixed floating ball (5) by the rope (10), and the length of the rope (10) depends on the maximum depth that the rope (1) needs to dive. According to actual sea conditions and wave conditions, it can be selected in the range of 2.0m ~ 4.0m, so that the maximum diving depth of the rope (1) can reach 4.0m ~ 8.0m. The setting of fixed float (5) is in order to guarantee that anchor rope (4) is in tension state all the time, controls the maximum dive depth of rope (1) simultaneously. The breeding object (3) is directly tied to the rope (1), and in order to balance the weight of the breeding object (3), a balance float string (2) is uniformly suspended on the rope (1). The breeding object (3) will gradually increase in weight, so in the breeding process, it is necessary to constantly adjust and balance the buoyancy provided by the floating ball string (2). There are two ways to realize: one is to replace the whole balance float string (2), and the balance float string (2) connects floats of appropriate size through ropes, and then replaces them as a whole; ), the number of small floats is continuously increased. In order to realize the arbitrary control of the diving depth of the rope (1), the two ends and the middle part of the rope (1) are respectively connected with the water layer regulating float (6) through the depth regulating rope (7). Since most of the weight of the cultured object (3) is offset by the balance float string (2), in order to realize stable sinking, the weight (8) and the rope (1) are respectively tied to the bottom of the depth control rope (7). The depth of diving can be controlled by adjusting the length of depth regulation rope (7).

In the above-mentioned scheme, each rope can adopt polyethylene material, and its diameter size depends on the breeding scale, and the diameter of general rope (1) and anchor rope (4) should be suitably larger. Various floats or floats can be made of materials such as plastic floats, glass floats or foam floats. Although there has been shown and described with reference to preferred examples, it will be understood by workers of ordinary skill in the art that various changes in form and details may be made within the scope of the claims.
