Description

Technical Field

[0001] The present invention relates to the technical field of fishery aquaculture, and particularly to a fishery aquaculture device that can be assembled on the water surface. Background Art

[0002] Fishery aquaculture refers to the production activity of artificially cultivating and breeding various aquatic economic animals and plants using water areas. The reproduction of fry and fingerlings is an important basic link in fishery aquaculture. High-quality fry and fingerlings are the prerequisite for obtaining high yields and high efficiency in fishery aquaculture. Through scientific reproduction techniques, sufficient quantities, strong constitutions, and uniform specifications of fry and fingerlings can be cultivated to provide good seedling resources for the subsequent aquaculture stage. A fishery aquaculture device refers to various equipment and facilities used in the process of fishery aquaculture, providing a suitable growth environment and aquaculture conditions for the reproduction of fry and fingerlings to achieve high yields, high efficiency, and sustainable development of fishery aquaculture.

[0003] In the prior art, during fishery aquaculture, centralized aquaculture and management are carried out through floating cages, enabling fry and fingerlings to live in a water environment close to nature, which is beneficial to the growth and development of fry and fingerlings. A floating cage generally consists of an anchoring system to fix a floating platform, and then the netting is installed on the hooks of the floating platform, causing the netting to naturally sink into the water. However, the part of the netting in the water is still in a floating and swinging state. When the water flow fluctuates greatly, it is very easy to drive the netting in the water to swing and tilt, resulting in an unstable living environment for the fry, increasing the stress response of the fry, affecting its normal feeding, growth, and development, and being unfavorable to fishery aquaculture.

[0004] Therefore, we propose a fishery aquaculture device that can be assembled on the water surface to solve the problems raised in the above background art. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1.

Sodium alginate is rich in various minerals and trace elements, has good biocompatibility and digestibility, and the fry and fingerlings can better absorb and utilize the nutrients therein, which helps to promote the growth and development of the fry and fingerlings.

[0020] 3. When the present invention is used, the first floating block and the second floating block are movably connected through a hook ring and a floating hook, the floating compensation plate fills the gap between the first floating block and the second floating block, and the floating compensation strip fills the gap between the walking floating platform and the assembly floating platform, thereby improving walking safety.

Two fixing strips 416 are fixedly installed on the tops of both of the two weight-increasing boxes 403. Every two adjacent fixing strips 416 among the four fixing strips 416 form a group. Two connecting rings 417 are installed on the outer surfaces of the two groups of fixing strips 416 through bolts.The inner walls of the four connecting rings 417 are respectively fixedly installed at the tops of one ends of the four net support rods 402. The output ends of the two waterproof motors 424 are respectively fixedly connected to one ends of the two flipping rods 401. The other ends of the two flipping rods 401 are respectively movably embedded in the outer surfaces of one sides of the two support plates 425. Arc-shaped grooves 415 are respectively formed in one sides of the two weight-increasing boxes 403. The outer surfaces of the other sides of the two arc-shaped flow dividing plates 405 are respectively movably embedded in the two arc-shaped grooves 415. The outer surfaces of one sides of the two gaskets 413 are respectively attached to the outer surfaces of one sides of the two weight-increasing boxes 403. Support frames 426 are respectively fixedly installed at the bottoms of the two waterproof motors 424. The two support frames 426 and the two support plates 425 are all installed on the top of the assembled floating platform 3. One ends of every two adjacent ones of the four net support rods 402 are connected by bolts. The assembled floating platform 3 includes a plurality of first floating blocks 301, a plurality of second floating blocks 302 and a plurality of floating compensation plates 303. Hook rings 304 are respectively fixedly connected to the outer surfaces of both sides of the plurality of first floating blocks 301. The fishery breeding assembly 2 includes a fry breeding net 201 and four right-angle connectors 202. A plurality of binding ropes 204 are fixedly connected to the top of the fry breeding net 201. Four floating rods 203 are arranged at the top of the fry breeding net 201. The plurality of binding ropes 204 are evenly divided into four groups. The four groups of binding ropes 204 are respectively movably connected to the outer surfaces of the four floating rods 203. The bottoms of the four right-angle connectors 202 are respectively installed on the tops of four of the floating compensation plates 303 by bolts. Both ends of the four floating rods 203 are respectively installed in the four right-angle connectors 202 by bolts.,

[0038] In this embodiment, when in use, the waterproof motor 424 and the flowmeter 420 are both electrically connected to an external control system. Mooring rings are installed at the bottoms of the walking floating platform 1 and the assembled floating platform 3. The walking floating platform 1, the assembled floating platform 3 and the fishery breeding assembly 2 are fixed at specific water area positions through an anchoring system and the mooring rings. Binding ropes 204 are connected to the four sides at the top of the fry breeding net 201. A plurality of annular grooves are formed in the outer surface of the floating rod 203. The binding ropes 204 are tied in the annular grooves on the outer surface of the floating rod 203, so as to tie the fry breeding net 201 to the floating rod 203. Under the action of gravity, the fry breeding net 201 naturally sinks into the water and spreads out. The two net support assemblies 4 are respectively located on both sides of the fry breeding net 201, as Figure 1 shown. The initial state of the net support assembly 4 is as Figure 13As shown, the arrow direction in the figure is the rotation direction of the subsequent turning rod 401. First, start one of the waterproof motors 424. The rotation of the output end of the waterproof motor 424 drives the turning rod 401 to rotate, and drives the flow equalizing pipe 418 and the two net support rods 402 to rotate, further driving the weight increasing box 403 to rotate towards the inside of the fry breeding net 201. As the turning rod 401 rotates, the net support rod 402 and the weight increasing box 403 gradually rotate into the water and rotate towards the inside of the fry breeding net 201. When the turning rod 401 rotates 180 degrees, the waterproof motor 424 automatically shuts down. At this time, the two net support rods 402 rotate to the two corners on the same side inside the fry breeding net 201, and the weight increasing box 403 rotates to the bottom surface inside the fry breeding net 201. Then start the waterproof motor 424 in the other net support assembly 4 to work, so that the other two net support rods 402 rotate to the other two corners inside the fry breeding net 201. The net support rod 402 is arranged in an L shape. When the four net support rods 402 respectively rotate to the four corner positions inside the fry breeding net 201, four supporting points are respectively formed. Under the action of the four force points, the fry breeding net 201 is expanded into a square shape, as Figure 2As shown, the shape of the fry breeding net 201 is fixed. The stability of the square structure enables it to evenly disperse the water flow acting force through its four sides under the impact of water flow. Under the propping action of the net support rod 402, the swinging amplitude of the fry breeding net 201 is restricted. Even when the water flow is large, it can maintain a relatively stable shape and is not prone to large swings and tilts. In addition, the square fry breeding net 201 can make more full use of the space inside the floating cage, providing a more regular and spacious activity space for fry and fingerlings, which is beneficial to the growth and development of fry and fingerlings. One end of the water injection pipe 419 is connected to an external water injection device through a hose. After the net support rod 402 props the fry breeding net 201 into a square shape, the external water injection device is started, and water is transported into the water injection pipe 419 through the hose. Under the equalizing action of the flow equalizing pipe 418, the water is evenly transported into the two water outlet pipes 421, and then enters the inside of the net support rod 402 through the connecting pipe 423. At this time, the drain pipe 422 is rotated into an upward inclined state, and the water in the net support rod 402 flows downward along the inner wall of the net support rod 402 under the action of gravity. By injecting water into the net support rod 402, the weight of the net support rod 402 can be increased. When the water level in the net support rod 402 is higher than the water inlet pipe 406, the water will enter the weight increasing box 403 through the water inlet pipe 406 and fall on the arc-shaped diversion plate 405. There is a certain space between the two side edges of the arc-shaped diversion plate 405 and the inner wall of the weight increasing box 403, so that the water on the arc-shaped diversion plate 405 flows downward along the arc-shaped side edges and slowly flows to the sodium alginate 404 through the space on the side of the weight increasing box 403. Under the action of the arc-shaped diversion plate 405, the water flow is prevented from directly impacting the sodium alginate 404, causing the sodium alginate 404 to fly to other dead corners and being unable to absorb water, affecting the subsequent water absorption and swelling effect of the sodium alginate 404. During the water injection process, the water volume is detected by the flow meter 420. When the flow rate reaches the set threshold value, the water injection device is closed to avoid injecting too much water into the weight increasing box 403. The sodium alginate 404 has a certain water absorption property and will swell into a gel-like substance after absorbing water. This is because the hydrophilic groups in the sodium alginate 404 molecules interact with water molecules, and the water molecules enter between the molecular chains, causing the molecular chains to stretch and form a three-dimensional network structure, thereby fixing a large amount of water in it. Appearances show an increase in volume, a softer texture and a certain elasticity. Due to absorbing a large amount of water, its overall weight will increase significantly, thus increasing the overall weight of the net support rod 402, which is beneficial for the net support rod 402 to generate a greater gravity to overcome the upward or lateral acting force of the water flow on the net, preventing the net from floating upward or deforming due to the action of the water flow, and ensuring that the net always maintains a good propped state, providing a stable living space for fry. The increase in the weight of the net support rod 402 also helps to lower the overall center of gravity of the assembled floating platform 3, improving the stability and safety of the floating cage.Under the action of the net support component 4, the net can always maintain a stable square expanded shape, preventing the net from swinging greatly or even tilting with the water flow, providing a stable living environment for fry, and solving the problem that in the process of using a floating cage, the net in the water part is in a floating and swinging state. When the water flow fluctuates greatly, it is easy to drive the net in the water to swing and tilt, resulting in an unstable living environment for fry, increasing the stress response of fry, affecting their normal feeding, growth and development, and being unfavorable to fishery farming.

[0039] Embodiment 2: As Figures 4 - 7 shown, both net support components 4 include a turning rod 401 and a weight box 403. Two net support rods 402 are installed on the outer surfaces of the two turning rods 401 through bolts. Sodium alginate 404 is arranged inside the two weight boxes 403. A plurality of water inlet pipes 406 are fixedly connected to the tops of the two weight boxes 403. Sealing plates 411 are fixedly installed on the outer surfaces of one sides of the two arc-shaped flow dividing plates 405. Sealing gaskets 413 are fixedly connected to the outer surfaces of one sides of the two sealing plates 411. Fixed blocks 409 are fixedly installed inside the two weight boxes 403. Half threaded rods 410 are threadedly embedded inside the two fixed blocks 409. T-shaped sealing sleeves 412 are fixedly connected to the outer surfaces of the two half threaded rods 410. Sealing holes 414 are opened on the outer surfaces of the other sides of the two sealing plates 411. The outer surfaces of the two T-shaped sealing sleeves 412 are respectively fitted with the inner walls of the two sealing holes 414. A plurality of water outlet holes 407 are opened at the bottoms of one ends of the four net support rods 402. Sealing rings 408 are fixedly connected to the inner walls of the plurality of water outlet holes 407. The outer surfaces of the plurality of water inlet pipes 406 are respectively fitted with the inner walls of the plurality of sealing rings 408. The plurality of water inlet pipes 406 are evenly divided into four groups. One ends of the four groups of water inlet pipes 406 respectively extend into the four net support rods 402. Two fixing bars 416 are fixedly installed on the tops of the two weight boxes 403. Every two adjacent fixing bars 416 among the four fixing bars 416 form a group. Two connecting rings 417 are installed on the outer surfaces of the two groups of fixing bars 416 through bolts. The inner walls of the four connecting rings 417 are respectively fixedly installed on the tops of one ends of the four net support rods 402. The output ends of the two waterproof motors 424 are respectively fixedly connected to one ends of the two turning rods 401. The other ends of the two turning rods 401 are respectively movably embedded in the outer surfaces of one sides of the two support plates 425.

[0040] In this embodiment, during use, by the reverse rotation of the waterproof motor 424, the net support rod 402 and the weight-increasing box 403 rotate in the reverse direction and are withdrawn from the fry breeding net 201 to restore to the initial state. Then, the net support rod 402 is removed from the outer surface of the flipping rod 401, and then the bolt between the connecting ring 417 and the fixing strip 416 is removed. Finally, the weight-increasing box 403 is removed from the net support rod 402, and the water inlet pipe 406 is pulled out from the sealing ring 408, then the weight-increasing box 403 can be removed separately. Then, the semi-threaded rod 410 is rotated to screw it out of the fixing block 409, and at the same time, the T-shaped sealing sleeve 412 is driven to leave the sealing hole 414. The sealing plate 411 is removed from the side of the weight-increasing box 403, and the arc-shaped flow dividing plate 405 is pulled out from the inside of the weight-increasing box 403, then the gel-like sodium alginate 404 in the weight-increasing box 403 can be poured out and fed to the fry as feed. Sodium alginate 404 is rich in various minerals and trace elements, such as potassium, sodium, calcium, magnesium, etc., which are all essential nutrients for the growth of fry and fingerlings. In addition, sodium alginate 404 has good biocompatibility and digestibility, and fry and fingerlings can better absorb and utilize the nutrients in it, which helps to promote the growth and development of fry and fingerlings. Its gel-like property is also convenient for fry and fingerlings to feed, and it will not be easily dispersed and lost in water like some powdered feeds. Compared with some artificial synthetic feeds, sodium alginate 404, as a natural feed raw material, has less pollution to water quality, is beneficial to maintaining the cleanliness and stability of the breeding water body, and creates a good growth environment for fry.

[0042] In this embodiment, during use, the floating hook 305 on the side of the second floating block 302 is hooked into the hook ring 304 on the side of the first floating block 301 to complete the connection between the first floating block 301 and the second floating block 302. Then, the hook ring 304 of the next first floating block 301 is looped around the floating hook 305 on the side of the just-connected second floating block 302. By repeating the above assembly process, an assembled floating platform 3 is formed. Then, the floating compensation plate 303 is embedded between the first floating block 301 and the second floating block 302, and the insertion rod 307 is inserted into the inside of the slot 306 to fill the gap between the first floating block 301 and the second floating block 302 through the floating compensation plate 303. And the floating compensation strip 6 is inserted into the first connection chute 5 and the second connection chute 7. As Figure 10 shown, the gap between the walking floating platform 1 and the assembled floating platform 3 is filled to prevent the staff from accidentally getting their feet stuck and causing danger when walking and feeding on the walking floating platform 1 or the assembled floating platform 3. Connection hooks are installed on the rear surface of the assembled floating platform 3 and the front surface of the walking floating platform 1.

The assembled floating platform 3 adopts a modular assembly method and can adjust the size of the assembled floating platform 3 according to needs, which is flexible, convenient, and has higher applicability.

[0043] The effect and working principle of the whole mechanism are as follows: tie the binding rope 204 to the annular groove on the outer surface of the floating rod 203, tie the fry breeding net 201 to the floating rod 203, and let the fry breeding net 201 naturally sink into the water under gravity and spread out. First, start one of the waterproof motors 424 to drive the flip rod 401 to rotate, and drive the flow equalizing pipe 418 and the two net support rods 402 to rotate, so that the net support rod 402 and the weight-increasing box 403 gradually rotate into the water and rotate toward one side of the inside of the fry breeding net 201. When the flip rod 401 rotates 180 degrees, the waterproof motor 424 is automatically turned off, and the two net support rods 402 rotate to the two corners on the same side of the inside of the fry breeding net 201. Then start the waterproof motor 424 in another net support assembly 4 to work, so that the other two net support rods 402 rotate to the other two corners inside the fry breeding net 201. The net support rods 402 are arranged in an L shape, and the four net support rods 402 respectively form four opening points. Under the action of the four stress points, the fry breeding net 201 is opened into a square shape. Start the external water injection equipment, and transport water to the water injection pipe 419 through the hose. Under the equalization action of the flow equalizing pipe 418, the water is evenly transported to the two water outlet pipes 421, and then enters the inside of the net support rod 402 through the connecting pipe 423. Then the water enters the inside of the weight-increasing box 403 through the water inlet pipe 406, and flows along the arc-shaped diverter plate 405 to the sodium alginate 404. During the water injection process, the water volume is monitored by the flow meter 420. When the flow rate reaches the set preset value, the water injection equipment is turned off. Sodium alginate 404 has a certain water absorption capacity. After absorbing water, it will expand to form a gel-like substance, and its overall weight will increase significantly, thereby increasing the overall weight of the net support rod 402, ensuring that the net always maintains a good open state. The reverse rotation of the waterproof motor 424 causes the net support rod 402 and the weight-increasing box 403 to reversely rotate, and the net support rod 402 and the weight-increasing box 403 are rotated out of the fry culture net 201 to restore the initial state. Then the net support rod 402 is removed from the outer surface of the flip rod 401, and then the bolts between the connecting ring 417 and the fixing bar 416 are removed, and finally the weight-increasing box 403 is removed from the net support rod 402, and the water inlet pipe 406 is pulled out of the sealing ring 408, and the weight-increasing box 403 can be removed separately. Then the semi-threaded rod 410 is rotated to spirally rotate out of the fixing block 409, and at the same time, the T-shaped sealing sleeve 412 is driven to leave the sealing hole 414, and the sealing plate 411 is removed from the side of the weight-increasing box 403, and the arc-shaped diverter plate 405 is pulled out from the inside of the weight-increasing box 403, and the gel-like sodium alginate 404 in the weight-increasing box 403 can be poured out and fed to the fry as feed.Hook the floating hook 305 on the side of the second floating block 302 into the hook ring 304 on the side of the first floating block 301 to complete the connection between the first floating block 301 and the second floating block 302. Repeat the above assembly process to form the assembled floating platform 3. Then, embed the floating compensation plate 303 between the first floating block 301 and the second floating block 302, and insert the insertion rod 307 into the inside of the slot 306 to fill the gap between the first floating block 301 and the second floating block 302 through the floating compensation plate 303. Insert the floating compensation bar 6 into the first connection chute 5 and the second connection chute 7 to fill the gap between the walking floating platform 1 and the assembled floating platform 3.
