Single shellfish multi-bag floating and sinking aquaculture rack

Abstract

Single shellfish multi-bag floating aquaculture frame, including: frame body, mesh bag, floating parts that cooperate with each other; frame body, mesh bag and floating parts are split structures and can be assembled into one; among them, frame body is durable Corrosion and anti-rust material, assembled by a group of detachable flat structural parts, multiple accommodation spaces are formed in the assembled frame, the mesh bag is set in the accommodation space, and the floating parts are fixed on the frame body. The shellfish seedlings are directly put into the net bag to realize single culture, the structure is simple, the transportation, installation and storage are convenient; at the same time, the quality of the product is guaranteed, and the service life of the net cage and the net bag is extended.

Description

Technical field: [0001] The invention belongs to the technical field of aquaculture, and relates to a single shellfish multi-bag floating-sink type aquaculture rack with simple structure and convenient transportation, installation and storage. Background technique: [0002] The structure of the aquaculture box in the prior art, such as the steel cage culture method described in the application number 201611038112.1, or, the structure is: the lower part is a net cage, the upper part is the structure of an air bag, and the net cage is tied with a rope between the net cage and the net cage. Together, its shortcoming of the structure of above-mentioned prior art is: [0003] 1. The net cages are generally metal structures, which are easily corroded in seawater, which affects the service life of the net cages and the quality of aquacultured aquatic products. [0004] 2. The built-in mesh bag is made of internal metal and outsourced with plastic. After a long time, the outer laye...

AI Technical Summary

Problems solved by technology

[0003] 1. The net cages are generally metal structures, which are easily corroded in seawater, which affects the service life of the net cages and also affects the quality of aquaculture products

[0004] 2. The built-in mesh bag is made of internal metal and outsourced with plastic. After a long time, the outer layer of plastic will fall off, and the inner layer of metal will be directly exposed in seawater, which is easy to corrode, which will also affect the quality of the product and reduce the service life of the mesh bag.

[0005] 3. The net cage floats on the sea surface through the function of the upper air bag. Due to the high height of the air bag, it will cause certain visual pollution.

[0006] 4. Since the air volume of the air bag cannot be adjusted, the net cage can only be bred at a fixed height, and it is impossible to choose the best aquaculture height according to the needs of the aquaculture products.

[0007] 5. There is no room for movement between the net cage and the net bag. When the waves hit, the farmed products will be unevenly distributed, and even washed to the corners of the net bag, so that some products will be squeezed at the bottom and die. Unable to obtain enough food and die, affecting the production rate

[0008] 6. Both the net cage and the net bag are of an integrated structure and cannot be disassembled, which makes it inconvenient to use, store and transport, which greatly increases the cost of storage and transport

[0009] 7. At present, there is no product with airbag and valve on the market, but the cover is used to seal the floating part tightly.

[0010] 8. Ropes are used to connect the net cages to the net cages. When the wind and waves are strong, the ropes are likely to break and the net cages will scatter and be washed away by the wind and waves, resulting in product loss.

[0011] 9. The compatibility between the net cage and the net bag is poor, and it can only be used together, and it cannot be used with the common net bag on the market, and the cost of use is increased.

[0012] 10. The net cages and net bags are fixed structures. When the finished products are taken out, the whole net cages need to be dragged to the ship, open the net cages, take out the products, and put them back one by one before they can be used again. The operation is cumbersome

[0013] 11. Due to the relatively high structure of the airbag, the height from the top to the bottom of the airbag is generally at least 1 meter. When the wind and waves are strong, the airbag will hit the airbag first and then the cage, which will make the cage easy to tilt, and the impact of the farmed products will also be uneven. They are even washed to the corners of the mesh bag, causing some products to die due to being squeezed at the bottom and unable to obtain sufficient food, which affects the production rate. At the same time, if the mesh cage is not sunk to the bottom in time, the mesh cage will been destroyed

[0014] 12. The connection between the airbag and the net cage is connected by a rope or cable tie, which is easy to loosen. When the wind and waves are strong, the rope is likely to break, so that the net cage and the airbag are scattered and washed away by the wind and waves, resulting in product loss.

[0015] 13. When the distribution of farmed products is uneven, one situation is that the mortality rate of the products increases, and the other situation is that the products cannot be polished to be bright and neat, which will affect the fullness of the meat quality
