Description

Technical Field

[0001] The utility model relates to the field of aquaculture, in particular to an oyster culture platform driven by wave energy. Background Art

[0002] When oysters are cultivated artificially, they are traditionally placed in hanging cages for cultivation. This traditional cultivation method exposes some problems during the cultivation process. First, due to the defects of the overall structure of the cultivation cages, the cultivation efficiency per unit area of ​​water is relatively low and the space utilization rate is poor. Secondly, once encountering severe weather such as typhoons, the cultivation cages located near the sea surface may be destroyed by the impact of waves. Structural damage will cause certain marine pollution and cause the oysters to escape or die on a large scale, resulting in greater economic losses.

[0003] At the same time, the short-term drying and exposure to sunlight during the cultivation process of oysters is more conducive to the growth and fattening of oysters. However, during the cage cultivation process, oysters cannot be lifted above the water surface, so the cultivation effect will be affected to a certain extent; if box-type cultivation is used to raise oysters, even if the tidal changes can be used to dry the oysters, the problem with the box-type cultivation method is that it is difficult to control the drying time. If the oysters are exposed to the air for too long, it will affect the growth effect of the oysters and even cause the death of the oysters, so manual monitoring and intervention are required.

[0004] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0005] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes a breeding platform with a simple structure, ingenious design, and reasonable layout, which can effectively protect oysters from being damaged in severe sea conditions. The utility model can move part of the breeding cage above the water surface without human intervention to increase the growth rate of oysters and accelerate fattening.

[0006] The technical solution of the utility model is: a wave energy driven oyster culture platform, comprising a platform body 1, characterized in that: the platform body 1 comprises a plurality of hollow shells 2 parallel to each other, adjacent hollow shells 2 are connected by a plurality of cross beams 3, a plurality of groups of support frames 4 are arranged on the platform body 1, and a rotating cage 5 is rotatably supported on the support frame 4,

[0007] The platform body 1 is also provided with a plurality of Salter-type nodding duck mechanisms 6, and the output end of each Salter-type nodding duck mechanism 6 is connected to the rotating shaft of a rotating cage 5 through a pulley transmission pair.

[0013] Compared with the prior art, the utility model has the following advantages:

It aims at the problems existing in the traditional oyster culture devices and methods (cage culture), and designs a culture platform with a special structure. It can realize the lifting and lowering action of the platform itself by means of water injection / drainage, so as to transfer the oysters to a certain water depth less affected by wind and waves before the typhoon comes, so as to achieve the effect of protecting the oysters; at the same time, it can use the wave energy collection device to drive the rotating cage to rotate, so that the oysters in multiple culture cages in the rotating cage automatically move to the surface of the water after a certain time interval, so that the oysters can be dried and exposed to light without manual operation, which is more conducive to the growth and fattening of oysters. In addition, the manufacturing process of this culture platform is simple and the manufacturing cost is low, so it can be said that it has many advantages, and is particularly suitable for promotion and application in this field, and its market prospects are very broad.

[0018] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figures 1 to 3 As shown: A wave energy driven oyster culture platform comprises a platform body 1, the platform body 1 comprises a plurality of hollow shells 2 parallel to each other, adjacent hollow shells 2 are connected by a plurality of cross beams 3, a plurality of support frames 4 are arranged on the platform body 1, a rotating cage 5 is rotatably supported on the support frame 4,

[0019] The platform body 1 is also provided with a plurality of Salter-type nodding duck mechanisms 6, and the output end of each Salter-type nodding duck mechanism 6 is connected to the rotating shaft of a rotating cage 5 through a pulley transmission pair.

[0020] The four corners of the platform body 1 are connected to buoys 8 through ropes 7.

[0022] One end of the arc plate 15 is hinged to one support plate 12, and the other end is matched with a buckle 16 provided on the other support plate 12.

[0023] The breeding cage 14 is cylindrical and closed at both ends. The surface of the breeding cage 14 is provided with second through holes 17 distributed in an array.

[0024] The hollow shell 2 is provided with a water connection pipeline and a gas connection pipeline.

[0025] The working process of the wave energy driven oyster culture platform of the embodiment of the utility model is as follows: the oyster seedlings to be cultured are placed in the culture cages 14 according to a certain culture density, and then a plurality of culture cages 14 are fixedly connected between the end plate 10 and the partition plate 13 to form a culture cage group, and the arc plate 15 is closed and its end is fixed by the buckle 16. At this time, the arc plate 15 is located outside the culture cage 14 to prevent the culture cage 14 from falling off the rotating cage 5;

[0026] Under normal conditions, all hollow shells 2 are filled with air, the platform body 1 floats on the water surface as a whole, a part of the rotating cage 5 is located below the water surface, and a part is located above the water surface, and the wave energy collection device 6 can convert wave energy into kinetic energy, and transmit it to the rotating shaft of the rotating cage 5 corresponding thereto through the pulley transmission pair, that is, drive the rotating cage 5 to rotate relative to the platform body 1, and the rotation of the rotating cage 5 will ensure that a part of the breeding cage 14 is always located above the water surface, and the oysters in this part of the breeding cage 14 will be exposed to drying and light. Since the rotating cage 5 is continuously rotating, that is to say, all oysters will be exposed to drying and light during the breeding process, compared with the traditional hanging cage breeding, the breeding effect can be effectively improved; compared with the traditional box-type breeding method, the oysters in the device will not experience long-term drying and light exposure, and their survival rate can be guaranteed;

[0027] If a typhoon occurs, a pipe connected to the water pump outlet can be connected to the water connection pipe, and seawater can be injected into the hollow shell 2 by the water pump to increase the overall mass of the platform body 1, so that the platform body 1 sinks below the water surface, thereby protecting the oysters; at this time, only the buoy 8 floats on the water surface (a positioning rope needs to be connected to the platform, and the other end of the positioning rope is connected to an anchor), which is convenient for the aquaculture personnel to find the platform afterwards;

[0028] After the typhoon passes, a pipeline connected to the air pump outlet is connected to the air connection pipeline, and air is injected into the hollow shell 2 by the air pump to squeeze out the seawater therein through the water connection pipeline, and the platform body 1 as a whole floats to the water surface again;

[0029] Since the central tube 9 of the rotating cage 5 is a hollow cylindrical structure, it will generate a certain buoyancy in the water. This design can reduce the load of the rotating cage 5 and is more conducive to maintaining a stable working state.
