Description

Technical Field

[0001] This invention relates to the field of deep-sea aquaculture technology, specifically to an aquaculture fishing platform and its usage method for aquatic ranching. Background Technology

[0002] Marine ranching refers to the planned and purposeful release of marine resources such as fish, shrimp, shellfish, and algae into a certain sea area using large-scale fishery facilities and a systematic management system, taking advantage of the natural marine ecological environment.

[0003] Chinese patent CN118525785A discloses an integrated platform combining deep-sea aquaculture and sea fishing. The main hull can be made to float and submerge by adjusting the ballast water volume of 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 but no top surface.

[0004] When the aforementioned aquaculture and fishing platform is in use, the main hull is raised and lowered by adjusting the ballast water volume in the ballast tank. The depth of the aquaculture net sinking to the seabed is controlled by controlling the raising and lowering of the platform. As a result, the depth of the aquaculture net is limited by the height of the fishing platform, making it inconvenient for the aquaculture of deep-sea fish. Summary of the Invention

The limiting block is slidably connected in the movable groove. The end of the reset spring away from the locking sleeve is fixedly installed with the right end of the pin.

[0012] As a preferred embodiment of the aquaculture and sea fishing platform of the present invention, mounting plates are fixedly installed on both sides of the side flexible net, and limiting pulleys are connected at intervals on both sides of the side flexible net. The limiting component includes a lifting plate fixedly connected to a steel mesh, and a lifting plate is fixedly connected to one side of the mounting plate.

[0013] As a preferred embodiment of the aquaculture and sea fishing platform of the present invention, the lifting plate has T-shaped grooves on both sides and lifting grooves on the surface of the lifting plate. The top of the lifting plate is fitted with a second lifting plate, and the bottom of the second lifting plate has a slider that slides in the lifting groove. The outer wall of the first lifting plate slides along the inner wall of the second lifting plate.

[0015] As a preferred embodiment of the aquaculture and sea fishing platform of the present invention, a guide frame is fixedly installed on the top of the fixed plate. The guide frame has a slide that gradually widens proportionally. The slide at the bottom of the guide frame is aligned with the T-shaped slide groove and has the same size. The slide at the top of the guide frame has a large opening, which can guide the limiting pulleys at both ends of the side soft net to smoothly enter the limiting component.

[0016] As a preferred embodiment of the aquaculture and sea fishing platform of the present invention, the output end of the motor is fixedly connected to a drive gear, a driven gear meshes below the driven gear, the driven gear is rotatably connected to the top of the U-shaped slide column, a limit bracket is provided on one side of the drive gear and the driven gear, the limit bracket limits the drive gear and the driven gear, a conical slide column one is fixedly connected to the top of the U-shaped slide column, a rotating cylinder is fixedly connected to the side of the driven gear away from the limit bracket, the conical slide column one is slidably connected inside the rotating cylinder, a conical slide column two is slidably connected inside the rotating cylinder, a ratchet ring is sleeved on the rotating cylinder, and one side of the ratchet ring is fixedly connected to the rotating roller.

[0017] To achieve the above objectives, the present invention provides the following technical solution: a method for use in aquatic ranching aquaculture, comprising the following steps:

[0018] First, the locking assembly is pulled by the output end of the cylinder to release the limit on steel mesh one, and at the same time, the lock on one end of the rotating roller is also released. After the lock is released, steel mesh one and steel mesh two will slide down along steel mesh three under their own weight. The limiting slider two on the inner wall of steel mesh two will slide down along the limiting groove two on the outer wall of steel mesh three, and the limiting slider one on the inner wall of steel mesh one will slide down along the limiting groove one on the outer wall of steel mesh two. Steel mesh one slides from the top to the bottom of steel mesh two, and steel mesh two drives... Steel mesh one slides down from the top to the bottom of steel mesh three, opening up the breeding space between steel mesh one, steel mesh two, and steel mesh three. Steel mesh one simultaneously drives the side soft wire meshes on all four sides to extend downwards and lay down. The support and limiting components of the steel mesh ensure that the side soft wire meshes and bottom soft wire meshes remain taut within the steel mesh. The movement of the side soft wire meshes pulls the rotating rollers, which rotate and release the mesh. The bottom ends of the side soft wire meshes on all four sides are connected to the bottom soft wire meshes, and the meshes are laid inside the connection between steel mesh one, steel mesh two, and steel mesh three.

[0019] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0020] 1. By rotating the rollers, the side flexible wire mesh inside the steel mesh is retracted. At the same time, the side flexible wire mesh pulls the steel mesh up gradually. The depth of the mesh in the water can be adjusted according to the type of fish being farmed, allowing for the simultaneous farming of fish at different water depths. The increased space helps provide sufficient activity range and growth space, providing a suitable living environment for different types of fish and improving farming efficiency. By setting up a double-layer mesh, the outer steel mesh mainly serves as structural support, supporting and limiting the inner side and bottom flexible wire meshes, and effectively resisting physical damage to the platform from the external environment.

[0021] 2. The steel mesh support and limiting components keep the side and bottom flexible wire meshes taut within the mesh, preventing them from tangling with the waves. The limiting measures make the nets easier to manage and operate, reducing tangling in the water, facilitating net retrieval and cleaning, and reducing the difficulty of manual operation. Furthermore, the inner side and bottom flexible wire meshes are flexible and elastic, preventing excessive tension and providing more precise protection.

[0022] 3. By pulling the locking assembly through the output end of the cylinder, steel mesh one and the rotating roller are unlocked simultaneously, causing steel mesh one and steel mesh two to fall. At the same time, the internal bottom soft wire mesh and side soft wire mesh move downwards. By extending and laying the side soft wire mesh, the rotating roller is rotated to release the mesh. The simultaneous extension and laying greatly reduces the time and labor intensity of step-by-step operations. Both unfold synchronously during the lowering process, which can quickly complete the installation of the entire mesh, save working time, and improve work efficiency.

[0023] 4. The steel mesh first simultaneously drives the four sides of the flexible wire mesh to extend downwards. The movement of the flexible wire mesh pulls the rotating roller to simultaneously release the mesh. The bottom ends of the four sides of the flexible wire mesh are connected to the bottom flexible wire mesh. It is laid inside the connection between steel mesh first, steel mesh second, and steel mesh third. By gathering the single-sided meshes around the perimeter into a net box, the breeding space can be effectively expanded. When not needed, it can be folded up. Each side flexible wire mesh is flattened and rolled back onto the rotating roller. The condition of the side flexible wire mesh can be clearly observed to see if it is damaged. This avoids the nets from getting tangled and knotted, saves space, and is convenient for storage. Attached Figure Description

[0037] The present invention will be further described below with reference to embodiments.

[0038] Example 1

[0039] Reference Figures 1-3 , Figure 6This is the first embodiment of the present invention, which provides an aquaculture fishing platform, including an aquaculture fishing platform body 100. A steel mesh extension mechanism 200 is fixedly installed on the aquaculture fishing platform body 100. The steel mesh extension mechanism 200 includes a steel mesh three 207 fixedly installed on the aquaculture fishing platform body 100. A steel mesh two 204 is slidably connected to the outer wall of the steel mesh three 207. A steel mesh one 202 is slidably connected to the outer wall of the steel mesh two 204. Telescopic components are provided between each steel mesh. The telescopic components can extend the interconnected steel meshes. A cylinder 201 that can drive the steel mesh extension is fixedly installed on the aquaculture fishing platform body 100. A locking component is fixedly installed on the output end of the cylinder 201. A horizontal grid plate is provided at the bottom end of the steel mesh one 202, so that the steel mesh one 202, the steel mesh two 204 and the steel mesh three 207 are connected.

[0040] A soft net retrieval mechanism 300 is provided on the steel mesh extension mechanism 200. The soft net retrieval mechanism 300 includes a support frame fixedly connected to the main body 100 of the aquaculture and sea fishing platform. A rotating roller 302 is rotatably connected to the support frame. Side soft net 303 is wound on the rotating roller 302. A motor 301 is fixedly installed at one end of the rotating roller 302. A drive assembly is fixedly connected to the output end of the motor 301. A rotating roller 302 is provided on one side of the drive assembly. Side soft net 303 is laid on all four sides of the steel mesh 202. Limiting components are provided between each side soft net 303 to prevent the side soft net 303 from moving away from the surrounding side soft net 303. The sides are connected together. The bottom of the side flexible wire mesh 303 is equipped with a bottom flexible wire mesh 304. There are eight limiting sliders 1 203, 2 limiting sliders 206, 1 limiting groove 205 and 2 limiting groove 208, which are all opened in pairs on the four sides of the steel mesh. Steel mesh 1 202, steel mesh 204 and steel mesh 3 207 are interlocked and are all quadrilaterals. The four sides of the steel mesh correspond to four side flexible wire meshes 303. The bottom flexible wire mesh 304 is fixedly installed on the horizontal grid plate. The steel mesh is made of lightweight and corrosion-resistant metal, such as stainless steel and aluminum alloy. The side flexible wire mesh 303 is made of high-strength and wear-resistant material, such as nylon, polyethylene and polyester.

[0041] Specifically, the output end of cylinder 201 pulls the locking assembly to release the limit on steel mesh 202, simultaneously releasing the lock on one end of the rotating roller 302. After the lock is released, steel mesh 202 and steel mesh 204 will slide down along steel mesh 307 under their own weight. The limiting slider 206 on the inner wall of steel mesh 204 will slide down along the limiting groove 208 on the outer wall of steel mesh 307, and the limiting slider 203 on the inner wall of steel mesh 202 will slide down along the limiting groove 205 on the outer wall of steel mesh 204. Steel mesh 202 slides from the top to the bottom of steel mesh 204, and steel mesh 202... 4. The steel mesh 1 202 slides from the top to the bottom of the steel mesh 3 207, opening up the breeding space between the steel mesh 1 202, steel mesh 204, and steel mesh 3 207. The steel mesh 1 202 simultaneously drives the side soft wire mesh 303 on all four sides to extend downwards and lay down. The support and limiting components of the steel mesh keep the side soft wire mesh 303 and the bottom soft wire mesh 304 taut inside the steel mesh. The movement of the side soft wire mesh 303 pulls the rotating roller 302 to rotate and release the mesh. The bottom ends of the side soft wire mesh 303 on all four sides are connected to the bottom soft wire mesh 304 and laid inside the connection between the steel mesh 1 202, steel mesh 204, and steel mesh 3 207.

[0042] The rotating roller 302 retracts the side flexible wire mesh 303 inside the steel mesh, while the side flexible wire mesh 303 pulls the steel mesh upwards. The depth of the mesh in the water can be adjusted according to the type of fish being farmed, allowing for the simultaneous farming of fish at different water depths. The increased space helps provide sufficient activity range and growth space, providing a suitable living environment for different types of fish and improving farming efficiency. By setting up a double-layer mesh, the outer steel mesh mainly serves as a structural support, supporting and limiting the inner side flexible wire mesh 303 and bottom flexible wire mesh 304, and can also effectively resist physical damage to the platform from the external environment.

[0043] Example 2

[0044] Reference Figures 2-4 , Figure 10In a second embodiment of the present invention, a marine aquaculture platform is provided. The telescopic assembly includes a limiting slider 203 fixedly connected to the inner wall of a steel mesh 202. A steel mesh 204 is slidably connected to the inner wall of the steel mesh 202. A limiting groove 205 is formed on the outer wall of a limiting groove 205, and the limiting slider 203 slides within the limiting groove 205. A limiting slider 206 is fixedly connected to the inner wall of the steel mesh 204. A steel mesh 207 is slidably connected to the inner wall of the steel mesh 204. A limiting groove 208 is formed on the outer wall of the steel mesh 207, and the limiting slider 206 slides within the limiting groove 208. The top of 207 is fixedly installed with the main body 100 of the aquaculture and sea fishing platform. The size of steel mesh 1 202 is larger than that of steel mesh 204. Steel mesh 204 is fitted inside steel mesh 1 202. The size of steel mesh 204 is larger than that of steel mesh 3 207. Steel mesh 3 207 is fitted inside steel mesh 204. The locking component includes a locking plate 209 fixed on steel mesh 1 202. The top of the locking plate 209 is provided with a beveled groove 210. The side of the locking plate 209 is provided with a locking hole 211. There are four locking plates 209, which are installed on the four sides of steel mesh 1 202 respectively.

[0045] A U-shaped slide column 212 is fixedly connected to the output end of cylinder 201. A locking sleeve 213 is fixedly installed at the bottom end of the U-shaped slide column 212. A drive assembly is provided at the top end of the U-shaped slide column 212. A reset spring 214 is fixedly installed inside the locking sleeve 213. A limit block 215 is fixedly connected to the left end of the locking sleeve 213. The U-shaped slide column 212 is U-shaped with its opening facing to the left. The top end of the U-shaped slide column 212 is longer than the bottom end. The limit block 215 is fixedly connected to the inner wall of the opening end of the locking sleeve 213.

[0046] A pin 216 is slidably connected inside the locking sleeve 213. A movable groove 217 is provided on the upper surface of the pin 216. A limiting block 215 is slidably connected inside the movable groove 217. The end of the reset spring 214 away from the locking sleeve 213 is fixedly installed with the right end of the pin 216. The pin 216 can be engaged into the locking hole 211 on the locking plate 209 to limit and lock the steel mesh 202. The pin 216 slides inside the locking sleeve 213. The left end of the pin 216 is rounded. The pin 216 is limited by the limiting block 215 and the movable groove 217 to prevent the pin 216 from falling out of the locking sleeve 213.

[0047] Specifically, the output end of cylinder 201 drives the U-shaped sliding column 212 to slide to the right, causing the bottom pin 216 of the U-shaped sliding column 212 to move out of the locking hole 211 on the locking plate 209, releasing the pin lock on the steel mesh 202. At the same time, the top of the U-shaped sliding column 212 releases the lock of the drive assembly, and the steel mesh 202 and steel mesh 204 fall, causing the side flexible wire mesh 303 to extend, pulling the rotating roller 302 to rotate and release the mesh. After the steel mesh 202 and the internal side flexible wire mesh 303 fall, the output end of cylinder 201 pushes the U-shaped sliding column 212 to move and reset. The drive assembly is locked internally. The output of the motor 301 can drive the rotating roller 302 to rotate and retract the fallen side flexible wire mesh 303. The taut side flexible wire mesh 303 can pull the bottom steel mesh 202 to rise. The depth of the mesh in the water can be adjusted according to the type of fish being farmed. When the steel mesh 202 rises to the initial position, the locking plates 209 around the steel mesh 202 will contact the pins 216. The left end of the pins 216 will slide along the inclined groove 210 at the top of the locking plate 209 into the locking hole 211 to lock, thus completing the retrieval of the mesh.

[0048] Example 3

[0049] Reference Figures 7-10 In the third embodiment of the present invention, an aquaculture fishing platform is provided. Mounting plates 305 are fixedly installed on both sides of the side flexible net 303. Limiting pulleys 306 are connected at intervals on both sides of the side flexible net 303. The limiting component includes a lifting plate 307 fixedly connected to the steel mesh 202. The lifting plate 307 is fixedly connected to one side of the mounting plate 305. Mounting plates 305 are fixed on both sides of the bottom end of the side flexible net 303. The limiting pulleys 306 are spaced out and cover both sides of the entire side flexible net 303. The mounting plates 305 are aligned with the holes at the bottom end of the lifting plate 307.

[0050] The lifting plate 307 has T-shaped grooves 308 on both sides, and lifting grooves 309 on the surface of the lifting plate 307. The top of the lifting plate 307 is fitted with a lifting plate 310, and the bottom of the lifting plate 310 is engaged with a slider that slides in the lifting groove 309. The outer wall of the lifting plate 307 slides along the inner wall of the lifting plate 310.

[0051] The lifting plate 310 has T-shaped grooves 311 on both sides and lifting grooves 312 on its surface. A fixing plate 313 is sleeved on the top of the lifting plate 310. A slider that slides in the lifting groove 312 is engaged at the bottom of the fixing plate 313. The outer wall of the lifting plate 310 slides along the inner wall of the fixing plate 313.

[0052] T-shaped grooves 314 are provided on both sides of the fixed plate 313. The top of the T-shaped grooves 314 is fixedly connected to the upper surface of the steel mesh 207. The lifting plate 1 307, lifting plate 2 310 and fixed plate 313 have the same shape. The fixed plate 313 is larger than the lifting plate 2 310. The lifting plate 2 310 is larger than the lifting plate 1 307. The T-shaped grooves 1 308, T-shaped groove 2 311 and T-shaped groove 314 have the same shape. They are all T-shaped and fit the shape of the limiting pulley 306. Chamfers are provided at the connection points to facilitate the smooth entry of the limiting pulley 306.

[0053] A guide frame 315 is fixedly installed on the top of the fixed plate 313. The guide frame 315 has a slide that gradually widens proportionally. The slide at the bottom of the guide frame 315 is aligned with the T-shaped slide groove 314 and has the same size. The slide at the top of the guide frame 315 has a large opening, which can guide the limiting pulleys 306 at both ends of the side flexible wire mesh 303 to smoothly enter the limiting assembly.

[0054] A drive gear 316 is fixedly connected to the output end of the motor 301. A driven gear 317 meshes below the driven gear 317. The driven gear 317 is rotatably connected to the top of the U-shaped slide column 212. A limit bracket 318 is provided on one side of the drive gear 316 and the driven gear 317. The limit bracket 318 limits the drive gear 316 and the driven gear 317. A conical slide column 319 is fixedly connected to the top of the U-shaped slide column 212. A rotating cylinder 320 is fixedly connected to the side of the driven gear 317 away from the limit bracket 318. The conical slide column 319 is slidably connected inside the rotating cylinder 320. A conical slide column 321 is slidably connected inside the rotating cylinder 320. A ratchet ring 322 is sleeved on the rotating cylinder 320. One side of the ratchet ring 322 is fixedly connected to the rotating roller 302.

[0055] Specifically, when the locking component is released, the conical slide column 321 will slide into the rotating cylinder 320, so that the top of the conical slide column 321 no longer contacts the inner wall of the ratchet ring 322. The steel mesh 202 will drive the surrounding side flexible wire mesh 303 to extend and lay downwards, and at the same time drive the lifting plate 307 on the steel mesh 202 to slide downwards from the lifting plate 310. Then, the top of the lifting plate 310 slides from the top of the fixed plate 313 to the bottom. During this process, since the limiting pulleys 306 on both sides of part of the side flexible wire mesh 303 are already in the slide rails on both sides of the limiting component, as the steel mesh 202 moves downwards, the limiting pulleys 306 of the extended part of the side flexible wire mesh 303 will enter from the guide frame 315 and slide along the T-shaped slide groove 314, T-shaped slide groove 211 and T-shaped slide groove 308, so that the side flexible wire mesh 303 The two sides of 03 are fixed to the limiting components on both sides. When the output end of the cylinder 201 pushes the U-shaped slide column 212 to reset, the conical slide column 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, pushing out the conical slide column 321 in the rotating cylinder 320, so that the conical slide column 321 extends out and contacts and engages with the inner wall of the ratchet ring 322. The output end of the motor 301 drives the drive gear 316 to rotate, and the meshing driven gear 317 drives the rotating cylinder 320 to rotate the outer ratchet ring 322, so that the rotating roller 302 rotates to retract the side soft wire mesh 303 in the steel mesh. At the same time, the side soft wire mesh 303 pulls the steel mesh to gradually retract. The output end of the motor 301 rotates the conical slide column 321 upward and stops rotating. At the same time, the locking component fixes the steel mesh 202.

[0056] Furthermore, this embodiment only discloses a three-layer steel mesh protective structure. Depending on the actual aquaculture needs, the corresponding number of protective steel mesh layers and the corresponding depth of soft mesh structure can be set.

[0057] Example 4

[0058] Reference Figures 1-3 , Figure 6 This is the fourth embodiment of the present invention, which provides a method for use in aquatic ranching aquaculture, comprising the following steps:

[0059] First, the locking assembly is pulled by the output end of cylinder 201 to release the limit on steel mesh 202, and at the same time, the lock on one end of the rotating roller 302 is also released. After the lock is released, steel mesh 202 and steel mesh 204 will slide down along steel mesh 307 under their own weight. The limiting slider 206 on the inner wall of steel mesh 204 will slide down along the limiting groove 208 on the outer wall of steel mesh 307, and the limiting slider 203 on the inner wall of steel mesh 202 will slide down along the limiting groove 205 on the outer wall of steel mesh 204. Steel mesh 202 slides from the top to the bottom of steel mesh 204, and steel mesh 204... The steel mesh 202 slides from the top to the bottom of the steel mesh 207, opening up the breeding space between the steel mesh 202, steel mesh 204, and steel mesh 207. The steel mesh 202 simultaneously drives the side soft wire mesh 303 on all four sides to extend downwards. The support and limiting components of the steel mesh keep the side soft wire mesh 303 and the bottom soft wire mesh 304 taut inside the steel mesh. The movement of the side soft wire mesh 303 pulls the rotating roller 302 to rotate and release the mesh. The bottom ends of the side soft wire mesh 303 on all four sides are connected to the bottom soft wire mesh 304, and are laid inside the interconnected steel mesh 202, steel mesh 204, and steel mesh 207.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
