Description

Technical Field

[0001] The utility model relates to the field of aquaculture, in particular to an aquaculture cage. Background Art

[0002] Aquaculture cages are a method of breeding aquatic animals such as fish and shrimp using cages. Due to its advantages of low investment, high output, mobility and quick results, it has been widely developed in lakes and reservoirs across the country in a short period of time.

[0003] In the process of aquaculture through cages, screens are needed to screen and separate the aquatic products according to their different growth stages. The existing screens are mostly dragged under the nets on site through cables with floats, which is cumbersome to operate. Utility Model Content

[0004] The purpose of this utility model is to provide an aquaculture cage to solve the above technical problems.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: an aquaculture cage, comprising a floating frame, a hoop, a buoy, a net, a counterweight, a chute, a screen frame, a screen pool, and a fishing pool. The hoop is distributed at the bottom end of the floating frame, the buoy is installed at the bottom end of the floating frame through the hoop, the top end of the net is circumferentially fixed inside the floating frame, the counterweight is distributed at the bottom end of the net, the chute is respectively opened on the left and right parts of the floating frame, the screen frame is installed on the floating frame through the chute, the screen pool or the screen frame is used to separate the net from the outside of the floating frame, and the fishing pool or the screen frame is used to separate the net from the inside of the floating frame.

[0006] Based on the above technical solution, the screen frame includes a crossbeam, a traction rope, a slider, a support frame, a cable, and a floating block. The traction rope is connected to the middle part of the crossbeam, and the slider is respectively fixed to the front and rear parts of the bottom end of the crossbeam, and the slider is slidably connected to the slide groove. The support frame is respectively fixed to the bottom end of the slider, and the cable is fixed to the outside of the net through the support frame, and the floating block is distributed on the cable.

[0007] Based on the above technical solution, the traction rope pulls the crossbeam to slide left and right along the slide groove to screen the mesh.

[0008] Compared with the existing technology, the utility model has the following advantages: the utility model sets a slide on the floating frame of the aquaculture cage to install the screen frame, and the screen is divided into a screening pool and a fishing pool by sliding the drying rack and dragging the net. The operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1 to 3 As shown, an aquaculture cage includes a floating frame 1, a hoop 2, a buoy 3, a net 4, a counterweight 5, a chute 6, a screen frame 7, a screen pool 8, and a fishing pool 9. The hoop 2 is distributed at the bottom end of the floating frame 1, and the buoy 3 is installed on the bottom end of the floating frame 1 through the hoop 2. The top end of the net 4 is circumferentially fixed inside the floating frame 1, and the counterweight 5 is distributed at the bottom end of the net 4. The chute 6 is respectively opened on the left and right parts of the floating frame 1, and the screen frame 7 is installed on the floating frame 1 through the chute 6. The screen pool 8 or the screen frame 7 separates the net 4 from the outside of the floating frame 1, and the fishing pool 9 or the screen frame 7 separates the net 4 from the inside of the floating frame 1.

[0015] The screen frame 7 includes a crossbeam 10, a traction rope 11, a slider 12, a support frame 13, a cable 14, and a floating block 15. The traction rope 11 is connected to the middle part of the crossbeam 10, and the slider 12 is respectively fixed to the front and rear parts of the bottom end of the crossbeam 10, and the slider 12 is slidably connected to the slide 6. The support frame 13 is respectively fixed to the bottom end of the slider 12, and the cable 14 is fixed to the outside of the net 4 through the support frame 13. The floating block 15 is distributed on the cable 14.

[0016] The traction rope 11 pulls the crossbeam 10 to slide left and right along the chute 6 to screen the mesh.

[0017] The working principle of the present invention is as follows: when screening aquatic products, the traction rope 11 is pulled to pull the crossbeam 10 inward along the slide 6. The crossbeam 10 drives the cable 14 between the support frame 13 through the slider 12 to drag the outside of the net. As part of the net 4 is dragged outside the drying rack 7, a screening pool 8 is formed. All the aquatic products in the net 4 are accumulated in the fishing pool 9. The aquatic products in the fishing pool 9 are caught and screened. The aquatic products with complex conditions are screened out, and those that do not meet the standards are put into the screening pool 8, so that the screening is realized, and the operation is simple.

[0018] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, based on the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, replacements and variations made to the implementation methods are still within the scope of protection of the present invention.
