Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aquaculture, in particular to an aquaculture cage. Background Art
[0002] Cage aquaculture is a method of aquaculture in which cages made of mesh (netting) are placed in a certain water area. Cages are mostly set up in lakes, rivers, reservoirs and other waters with a certain water flow, fresh water quality and high dissolved oxygen content. High-density intensive breeding can be implemented. The mesh (netting) is made of synthetic fiber or metal wire. Cage aquaculture can be carried out in most water bodies, whether lakes, rivers or reservoirs. It can save a lot of land area for aquaculture, and does not compete with farmland, nor with industry and agriculture for water. It can improve the water quality of reservoirs and lakes. The fish production is high, and the fishing is convenient, live fish can be provided at any time, and mechanized fishery operations can be realized. At present, most of the fishing is done by hand-held scoop nets or by manual pulling nets. When using scoop nets to fish, it is easy to cause stress reactions in aquatic products, causing them to collide with the nets or scoop nets and be injured. They are prone to infection and death during transportation, which reduces the survival rate. Pulling nets to fish is time-consuming and labor-intensive. In the face of larger breeding areas, more manpower is usually required. Therefore, further improvements to the aquaculture cages are needed. Utility Model Content
[0003] In view of the above technical problems, the utility model provides a breeding cage which is convenient for catching aquatic products.
[0004] In order to solve the above technical problems, the utility model describes an aquaculture cage, comprising a frame, wherein the frame is fixedly connected to mesh panels on all sides except the top and bottom, the inner upper end and bottom of the frame are fixedly connected to a slide rod through a connecting piece, the top end of the slide rod is rotatably connected to a pulley, a sliding sleeve is provided on the slide rod, the slider is fixedly connected to the bottom net, a partition is fixedly connected to the top of the slide rod through a support rod, a motor is fixedly connected to the partition, the output end of the motor is fixedly connected to a spool, a traction rope is fixedly connected to the slider, and the other end of the traction rope is fixedly connected to the spool through a pulley.
[0005] Furthermore, the traction rope and the pulley are provided in two groups and are arranged diagonally.
[0006] Furthermore, the motor is a forward and reverse rotating motor.
[0007] Furthermore, the bottom net is in a downwardly concave semicircular shape.
[0008] Furthermore, the frame, sliding rod, slider, support rod and connecting piece are all covered with an anti-corrosion coating.
[0009] Compared with the prior art, the utility model has the following advantages:
[0010] 1. The utility model facilitates the capture of mature aquatic products by setting a liftable bottom net, which saves time and effort, reduces the stress response of aquatic products, does not cause excessive damage to aquatic products, increases the survival rate during transportation, and ensures the freshness when entering the market.
[0011] 2. By setting up a downwardly concave semicircular bottom net, when catching aquatic products, the aquatic products will be gathered together after the bottom net is raised, which facilitates subsequent salvage work. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] like Figures 1 to 3 The aquaculture cage shown includes a frame 1, and the frame 1 is fixedly connected to a mesh on all sides except the top and bottom. The upper inner end and bottom of the frame 1 are fixedly connected to a slide rod 2 through a connecting piece, and the top of the slide rod 2 is rotatably connected to a pulley 7. A slider 5 is provided on the slide rod 2, and the slider 5 is fixedly connected to the bottom net 6. A partition 4 is fixedly connected above the slide rod 2 through a support rod 3, and a motor 9 is fixedly connected to the partition 4. The output end of the motor 9 is fixedly connected to a spool 10. A traction rope 8 is fixedly connected to the slider 5, and the other end of the traction rope 8 is fixedly connected to the spool 10 through the pulley 7.
[0018] In order to facilitate the lifting and lowering of the bottom net 6, two groups of traction ropes 8 and pulleys 7 are provided and arranged diagonally.
[0019] In order to freely control the rise and fall of the bottom net 6, the motor 9 is set to be a forward and reverse motor.
[0020] In order to facilitate the gathering of aquatic products when catching them, the bottom net 6 is set to a downwardly concave semicircular shape, which can also expand the activity area during aquaculture.
[0021] In order to increase the service life of the equipment and prevent rust and corrosion, the frame 1, the slide bar 2, the slider 5, the support rod 3 and the connecting parts are covered with an anti-corrosion coating.
[0022] The working process of this embodiment is as follows:
[0023] After the aquatic products are mature and need to be caught, the motor 9 is turned on to drive the spool 10 to rotate, and then the traction rope 8 is wound around the spool 10. The traction rope 8 drives the slider 5 to rise on the slide rod 2 through the pulley 7, and finally drives the bottom net 6 fixedly connected to the slider 5 to rise, so that the aquatic products accumulate at the bottom of the bottom net 6, which is convenient for subsequent salvaging of the aquatic products. After the salvage is completed, the motor 9 is controlled to reverse, and the bottom net 6 can be lowered to start a new round of breeding.
