Description

Technical Field

[0001] The utility model relates to the technical field of cage aquaculture, in particular to a support frame for cage aquaculture. Background Technique

[0002] A cage is a facility for aquaculture, usually composed of net materials and a frame, mainly used for cultivating aquatic organisms such as fish, shrimps, and shellfish in water bodies. The design of the cage allows water flow through, providing oxygen required for the cultured organisms, while preventing the cultured organisms from escaping or foreign organisms from invading. With the rapid development of the aquaculture industry, cage aquaculture, as an efficient and environmentally friendly aquaculture method, is increasingly favored. During the use of the cage, it needs to be supported, so a support frame for cage aquaculture is required.

[0003] The traditional support frame for cage aquaculture is usually fixedly structured. During the actual aquaculture process, the volume of fish is getting larger and larger, and the required activity space is getting larger and larger. During the aquaculture process, to ensure the best cage layout and aquaculture density, it is necessary to replace support frames of different specifications, which increases the aquaculture cost. Moreover, the traditional support frame for cage aquaculture is fixed to the bottom of the water and cannot be moved. When harvesting aquatic products, one can only take a boat to capture the aquatic products in the cage. During the capture process, the risk of falling into the water is likely to occur, reducing the practicability of the device. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a support frame for cage aquaculture.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A support frame for cage farming, comprising four sleeves. L-shaped fasteners are respectively fixed to the tops of two of the sleeves. A plurality of first through holes are linearly formed at equal distances at both ends of the tops of the two L-shaped fasteners. L-shaped plates are respectively fixed to the tops of the other two sleeves. Both ends of the two L-shaped plates are respectively slidably arranged on the inner side walls of the two L-shaped fasteners. A plurality of second through holes are linearly formed at equal distances at both ends of the tops of the L-shaped plates, and the plurality of second through holes correspond to the plurality of first through holes one by one. Bolts are arranged at both ends of the tops of the L-shaped fasteners, and the bolts penetrate through the first through holes and the bolts. Nuts are sleeved on the side walls of the bolts, and the nuts are adapted to the bolts. Support mechanisms are arranged inside all four sleeves. Fixing mechanisms for fixing the cage are arranged on the inner side walls of both L-shaped plates. Annular air bags are sleeved on the outer side walls of all four sleeves. The outer side walls of every two annular air bags are fixed with the same hose. An inflation mechanism for inflating the four annular air bags is arranged on the side wall of one of the hoses. A traction mechanism for towing the cage is arranged on the side wall of the L-shaped fastener. During the use of the device, a support frame is formed by combining the two L-shaped fasteners and the two L-shaped plates. The combined frame is an adjustable structure. When it is necessary to adjust the size of the cage according to the breeding density, the size of the combined frame can be adjusted without replacing the frame, reducing the breeding cost. When it is necessary to harvest aquatic products, the four annular air bags are inflated through the inflation mechanism. The combined frame floats on the water surface under the action of the four annular air bags. Cooperating with the traction mechanism, the cage is pulled to the shore without taking a boat for fishing, avoiding the risk of falling into the water and improving the practicability of the device.

[0007] As a further scheme of the utility model, the support mechanism includes a hydraulic push rod. The hydraulic push rod is arranged through the inner side wall of the sleeve.

One end of the spring is fixed to the side wall of the plug pin, and the other end of the spring is fixed to the bottom of the top plate. A bottom plate is fixed to the inner side wall of the L-shaped plate and is located directly below the top plate. A round hole is formed in the top of the bottom plate, and the plug pin is adapted to the round hole. Pull the four plug pins away from the tops of the four round holes respectively, so that the four springs are all in a compressed state. When fixing, place the four corners of the cage on the tops of the four round holes respectively, and release the four plug pins. The four springs return to their original state, so that the four plug pins enter the four round holes respectively again, and the fixing of the cage can be completed.

[0009] As a further solution of the present utility model, the inflation mechanism includes a connecting pipe, which is fixed on the side wall of one of the hoses. An air pump is externally connected to the connecting pipe to inflate the four annular air bags through the four hoses, causing the four annular air bags to expand.

After adjustment, the bolt is passed through the first through hole and the second through hole, and locked with the nut. The operation is simple, there is no need to replace the frame, and the breeding cost is reduced.

[0014] 2. When it is necessary to harvest aquatic products, the four annular air bags are inflated through the inflation mechanism, causing the four annular air bags to expand and releasing the support for the frame. At this time, the two L-shaped fasteners and the L-shaped plates float on the water surface under the action of the four annular air bags.
