[0003] Chinese patent CN118525785A discloses an integrated platform combining deep-sea aquaculture and sea fishing, which realizes the floating and diving of the main hull by adjusting the ballast water volume in the ballast tank. The aquaculture cage includes a side mesh structure and a bottom mesh structure. The side mesh structure and the bottom mesh structure are connected to the main hull to form a semi-enclosed structure with a bottom surface on the side but no top surface.

[0004] When the above-mentioned aquaculture and sea fishing platform is in use, the floating and sinking of the main hull are achieved by adjusting the ballast water amount in the ballast tank, and the depth of the aquaculture net sinking to the seabed is controlled by controlling the lifting and lowering of the platform, so that the depth of the aquaculture net is limited by the height of the sea fishing platform, which is not convenient for aquaculture of deep-water fish.

Steel mesh one slides from the top of steel mesh two to the bottom, and steel mesh two drives Steel mesh one slides from the top to the bottom of steel mesh three, so that the breeding space among steel mesh one, steel mesh two and steel mesh three is expanded, and the side soft wire meshes on the four sides are simultaneously driven to extend and lay downward through steel mesh one, and the side soft wire meshes and the bottom soft wire meshes are always kept straight in the steel mesh through the support and limit components of the steel meshes, and the rotating rollers are pulled by the movement of the side soft wire meshes to rotate and release the nets at the same time, and the bottom ends of the side soft wire meshes on the four sides are connected to the bottom soft wire mesh, and are laid inside the connected steel mesh one, steel mesh two and steel mesh three.

[0019] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0020] 1. The side soft wire net inside the steel net is retracted by rotating the roller, and the steel net is gradually raised by pulling the side soft wire net. The depth of the grid in the water can be adjusted according to the type of farmed fish, and fish of different water depths can be farmed at the same time. The increased space helps to provide sufficient range of activities and growth space, and can provide a suitable living environment for different types of fish, thereby improving farming efficiency. By setting up a double-layer grid, the outer steel net mainly plays a structural supporting role, supports and limits the internal side soft wire net and bottom soft wire net, and can also effectively resist physical damage to the platform caused by the external environment.

[0021] 2. The side soft wire nets and bottom soft wire nets are always kept straight in the steel net through the support and limit components, so that the side soft wire nets and bottom soft wire nets will not be entangled with each other with the shaking of the waves. The limiting measures make the nets easier to manage and operate, reduce the phenomenon of entanglement of the nets in the water, facilitate the recovery and cleaning of the nets, and reduce the difficulty of manual operation. The inner layer of the side soft wire nets and bottom soft wire nets are flexible and elastic, which can avoid excessive tension and provide more sophisticated protection.

[0022] 3. Pull the locking assembly through the output end of the cylinder to unlock the steel mesh one and the rotating roller at the same time, so that the steel mesh one and the steel mesh two fall down, and at the same time drive the internal bottom soft wire net and the side soft wire net to move downward, and drive the side soft wire net to extend and lay, pull the rotating roller to rotate, and release the net at the same time. The time and labor intensity of step-by-step operation can be greatly reduced. The two are launched synchronously during the lowering process, which can quickly complete the installation of the entire grid, save operation time, and improve work efficiency.

[0023] 4. The four side soft wire nets are extended and laid downward by steel net one at the same time. The movement of the side soft wire net pulls the rotating roller to rotate and release the net at the same time. The bottom ends of the four side soft wire nets are connected to the bottom soft wire net and laid inside the connected steel net one, steel net two and steel net three. By gathering the single-sided nets around into a net box, the breeding space can be effectively expanded, and it can be folded up when not needed. By flattening and rolling each side soft wire net back onto the rotating roller, it can be clearly observed whether the side soft wire net is damaged, avoiding entanglement and knotting between the nets, saving space and facilitating storage.

[0055] Specifically, when the locking assembly is released, the conical sliding post 21 will slide into the rotating cylinder 320, so that the top of the conical sliding post 21 will no longer contact the inner wall of the ratchet ring 322, and the steel mesh 1 202 will drive the surrounding side soft wire mesh 303 to extend and lay downward, and at the same time drive the lifting plate 1 307 on the steel mesh 1 202 to slide downward from the lifting plate 210, and then the top of the lifting plate 210 will slide from the top of the fixing plate 313 to the bottom. In this process, since the limiting pulleys 306 on both sides of the side soft wire mesh 303 are already in the slideways on both sides of the limiting assembly, as the steel mesh 1 202 moves downward, the limiting pulleys 306 of the extended part of the side soft wire mesh 303 will enter from the guide frame 315, and slide along the T-shaped slide groove 314, the T-shaped slide groove 2 311 and the T-shaped slide groove 1 308, so that the side soft wire mesh 3 The two sides of 03 are fixed on the limit assemblies on both sides. When the output end of the cylinder 201 pushes the U-shaped slide column 212 to reset, the conical slide column 1 319 at the top of the U-shaped slide column 212 will be inserted into the center of the rotating cylinder 320 along the center of the driven gear 317, and the conical slide column 2 321 in the rotating cylinder 320 will be pushed out, so that the conical slide column 2 321 extends out and contacts and engages with the inner wall of the ratchet ring 322, and the driving gear 316 is driven to rotate by the output end of the motor 301, and the rotating cylinder 320 is driven by the meshing driven gear 317 to rotate the ratchet ring 322 of the outer ring, so that the rotating roller 302 rotates to retract the side soft wire net 303 in the steel net, and at the same time, the steel net is gradually retracted by pulling the side soft wire net 303, and the conical slide column 2 321 is rotated upward by the output end of the motor 301 and then stops rotating, and the locking assembly fixes the steel net 1 202.

[0056] Furthermore, the present embodiment only discloses a three-layer steel mesh protection structure. According to actual breeding needs, a corresponding number of layers of protective steel mesh and a soft mesh structure of a corresponding depth can be set.

[0059] First, the locking assembly is pulled by the output end of the cylinder 201 to release the limit of the steel mesh 1 202, and the lock of one end of the rotating roller 302 is also released at the same time. After the lock is released, the steel mesh 1 202 and the steel mesh 2 204 will slide down along the steel mesh 3 207 under their own weight, and the limit slider 2 206 on the inner wall of the steel mesh 2 204 will slide down along the limit slide groove 2 208 on the outer wall of the steel mesh 3 207, and the limit slider 1 203 on the inner wall of the steel mesh 1 202 will slide down along the limit slide groove 1 205 on the outer wall of the steel mesh 2 204. The steel mesh 1 202 slides from the top of the steel mesh 2 204 to the bottom, and the steel mesh 2 204 Drive steel mesh 1 202 to slide from the top of steel mesh 3 207 to the bottom, so that the breeding space among steel mesh 1 202, steel mesh 204 and steel mesh 3 207 is expanded, and the side soft wire nets 303 on the four sides are simultaneously driven to extend and lay downward through steel mesh 1 202, and the side soft wire nets 303 and the bottom soft wire net 304 are always kept straight in the steel mesh through the support and limit components of the steel mesh, and the movement of the side soft wire net 303 pulls the rotating roller 302 to rotate and release the net at the same time, and the bottom ends of the side soft wire nets 303 on the four sides are connected to the bottom soft wire net 304, and are laid inside the connected steel mesh 1 202, steel mesh 204 and steel mesh 3 207.
