Description

Technical Field

[0001] The invention relates to the technical field of fishery breeding, in particular to a fishery breeding device that can be assembled on the water surface. Background Art

[0002] Fishery aquaculture refers to the artificial cultivation and propagation of various aquatic economic plants and animals using water bodies. The propagation of fry and fingerlings is a crucial and fundamental component of aquaculture. High-quality fry and fingerlings are prerequisites for high yields and efficiency in aquaculture. Scientific propagation techniques can produce sufficient numbers of healthy, well-sized fry and fingerlings, providing a good seed resource for subsequent aquaculture stages. Fishery aquaculture equipment refers to the various equipment and facilities used in aquaculture to provide a suitable growth environment and breeding conditions for fry and fingerling propagation, thereby achieving high yields, efficiency, and sustainable development.

[0003] In existing aquaculture, floating cages are used for centralized breeding and management. This allows fish fry and fingerlings to live in a near-natural aquatic environment, which is beneficial for their growth and development. Floating cages are typically anchored to a floating platform by an anchoring system, and then the net is attached to hooks on the platform, allowing it to naturally sink into the water. However, the submerged portion of the net remains dangling. High current fluctuations can easily cause the net to swing and tilt, leading to an unstable living environment for the fry, increasing their stress response, and affecting their normal feeding, growth, and development, which is detrimental to aquaculture.

[0017] Compared with the prior art, the present application has the following advantages:

[0018] 1. When using the present invention, a waterproof motor is started, and the net support rods are rotated to two corners inside the fish fry breeding net by rotating the flip rod.

[0038] In use, the waterproof motor 424 and the flow meter 420 are electrically connected with an external control system, the bottom parts of the walking floating platform 1 and the assembled floating platform 3 are installed with anchor rings, the walking floating platform 1, the assembled floating platform 3 and the fishery breeding assembly 2 are fixed in a specific water area position through an anchoring system and the anchor rings. The four edges of the top of the fry breeding net 201 are connected with the binding ropes 204, a plurality of annular grooves are formed in the outer surface of the floating rod 203, the binding ropes 204 are bound in the annular grooves in the outer surface of the floating rod 203, so that the fry breeding net 201 is tied on 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 located at the two sides of the fry breeding net 201 respectively, as shown in Figure 1 The initial state of the net support assembly 4 is as shown in Figure 13The arrow direction in the figure is the rotation direction of the subsequent turnover rod 401. First, start one waterproof motor 424, drive the turnover rod 401 to rotate through the rotation of the waterproof motor 424 output end, and drive the flow equalizing pipe 418 and the two net support rods 402 to rotate, further drive the weight box 403 to rotate to the inside of the fry culture net 201, with the rotation of the turnover rod 401, the net support rod 402 and the weight box 403 are gradually rotated to the water, and are rotated to one side of the inside of the fry culture net 201. When the turnover rod 401 rotates one hundred and eighty degrees, the waterproof motor 424 is automatically turned off, at this time, the two net support rods 402 are rotated to the two corners of the same side of the inside of the fry culture net 201, and the weight box 403 is rotated to the bottom surface of the inside of the fry culture 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 are rotated to the other two corners of the inside of the fry culture net 201. The net support rod 402 is L-shaped, when the four net support rods 402 are respectively rotated to the four corners of the inside of the fry culture net 201, four support opening points are formed, and the fry culture net 201 is opened into a square shape under the action of the four stress points, as shown in Figure 2The shape of the fish fry breeding net 201 is fixed, and the stability of the square structure enables it to evenly disperse the water flow force through the four edges under the impact of the water flow. Under the opening effect of the net support rod 402, the swing range of the fish fry breeding net 201 is limited, and even when the water flow is large, it can still maintain a relatively stable shape and is not prone to large-scale swinging and tilting. In addition, the square fish fry breeding net 201 can make more full use of the space inside the floating net cage and provide more regular and spacious living space for the fish fry and fry, which is beneficial to the growth and development of the fish fry and fry. One end of the water injection pipe 419 is connected to an external water injection device through a hose. When the net support rod 402 opens the fish fry breeding net 201 into a square shape, the external water injection device is started, water is transported into the water injection pipe 419 through the hose, and under the uniform distribution effect of the flow distributor 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 water outlet pipe 422 is turned into an upwardly inclined shape, 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, water will enter the weight increasing box 403 through the water inlet pipe 406 and fall on the arc-shaped flow distributor 405. The two sides of the arc-shaped flow distributor 405 are spaced apart from the inner wall of the weight increasing box 403, so that the water on the arc-shaped flow distributor 405 flows downward along the arc-shaped side and slowly flows onto the sodium alginate 404 through the space between the arc-shaped flow distributor 405 and the side of the weight increasing box 403. Under the action of the arc-shaped flow distributor 405, the water flow directly impacts the sodium alginate 404, causing the sodium alginate 404 to fly to other dead corners and fail to absorb water, affecting the subsequent water absorption and swelling effect of the sodium alginate 404. During the water injection process, the water flow is detected by the flow meter 420, and when the flow reaches the set pre-value, the water injection device is closed to avoid excessive water injection into the weight increasing box 403. The sodium alginate 404 has a certain water absorption and will swell to form a gel-like substance after absorbing water. This is because the hydrophilic groups in the sodium alginate 404 molecules interact with water molecules, 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, which appears as an increase in volume, a softening of texture, and a certain elasticity. Due to the absorption of a large amount of water, the overall weight increases significantly, thereby increasing the overall weight of the net support rod 402, which is conducive to the net support rod 402 generating greater gravity to overcome the upward or lateral force of the water flow on the net, preventing the net from floating up or deforming due to the action of the water flow, and ensuring that the net always maintains a good opening state to provide a stable living space for the fish 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 and improve the stability and safety of the floating net cage.Under the action of the net support assembly 4, the net can always maintain a stable square expanded shape, preventing the net from swinging greatly with the fluctuation of water flow or even tilting, providing a stable living environment for the fry, and solving the problem that the part of the net in the water is in a floating state during use of the floating cage. When the water flow fluctuates greatly, it is easy to cause the net in the water to swing and tilt, resulting in an unstable living environment for the fry, increasing the stress response of the fry, affecting their normal feeding, growth and development, and being detrimental to fishery farming.

[0039] Example 2: Figures 4-7 As shown, the two net support components 4 include a flip rod 401 and a weight-increasing box 403. The outer surfaces of the two flip rods 401 are both installed with two net support rods 402 by bolts. Sodium alginate 404 is set inside the two weight-increasing boxes 403. The tops of the two weight-increasing boxes 403 are fixedly connected with multiple water inlet pipes 406. The outer surfaces of one side of the two arc-shaped diverter plates 405 are fixedly installed with sealing plates 411. The outer surfaces of one side of the two sealing plates 411 are fixedly connected with sealing gaskets 413. The interiors of the two weight-increasing boxes 403 are both fixedly installed with fixed blocks 409. The interiors of the two fixed blocks 409 are both threadedly embedded with half-threaded rods 410. The outer surfaces of the two half-threaded rods 410 are fixedly connected with T-shaped sealing sleeves 412. The outer surfaces of the other sides of the two sealing plates 411 are opened with sealing holes 414. 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 provided at the bottom of one end of the support rod 402, and the inner walls of the plurality of water outlet holes 407 are fixedly connected with a sealing ring 408. 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, and one end of the four groups of water inlet pipes 406 respectively extends to the interior of the four net support rods 402. Two fixing bars 416 are fixedly installed on the top of the two weight-increasing boxes 403. Each two adjacent fixing bars 416 of the four fixing bars 416 form a group. The outer surfaces of the two groups of fixing bars 416 are respectively fixed with two connecting rings 417 by bolts. The inner walls of the four connecting rings 417 are respectively fixedly installed on the top of one end of the four net support rods 402. The output ends of the two waterproof motors 424 are respectively fixedly connected to one end of the two flip rods 401, and the other ends of the two flip rods 401 are respectively movably embedded in the outer surface of one side of the two support plates 425.

[0040] In this embodiment, in use, the net support rod 402 and the weight box 403 are reversed by the reverse rotation of the waterproof motor 424, and are turned out of the fry culture net 201, and the initial state is restored. Then the net support rod 402 is removed from the outer surface of the turnover rod 401, then the bolt between the connecting ring 417 and the fixed strip 416 is removed, finally the weight box 403 is removed from the net support rod 402, and the water inlet pipe 406 is pulled out of the sealing ring 408, that is, the weight box 403 can be removed alone. Then rotate the half-threaded rod 410 to screw it out of the fixed block 409, while driving the T-shaped sealing sleeve 412 away from the sealing hole 414, removing the sealing plate 411 from the side of the weight box 403, and pulling out the arc-shaped flow divider 405 from the inside of the weight box 403. The gelatinous sodium alginate 404 in the weight box 403 can be poured out as feed for fry. Sodium alginate 404 is rich in various minerals and trace elements such as potassium, sodium, calcium, magnesium, etc., which are essential nutrients for the growth of fry and fry. In addition, sodium alginate 404 has good biocompatibility and digestibility, and fry and fry can better absorb and utilize the nutrients in it, which helps to promote the growth and development of fry and fry. Its gelatinous properties also facilitate feeding of fry and fry, unlike some powdered feed that is easily dispersed and lost in water. Compared with some synthetic feed, sodium alginate 404 as a natural feed raw material causes less pollution to water quality, which is conducive to maintaining the cleanliness and stability of the culture water body and creating a good growing environment for fry.

[0043] The effect and working principle of the whole mechanism are as follows: the binding rope 204 is bound in the annular groove on the outer surface of the floating rod 203, the fish breeding net 201 is tied on the floating rod 203, and the fish breeding net 201 is naturally sunk into the water under the gravity and is spread out. First, one of the waterproof motors 424 is started to drive the turnover 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 rods 402 and the weight increasing boxes 403 are gradually rotated to the water and are rotated to one side of the inside of the fish breeding net 201. When the turnover rod 401 is rotated by one hundred and eighty degrees, the waterproof motor 424 is automatically turned off, at this time, the two net support rods 402 are rotated to the two corners of the same side of the inside of the fish breeding net 201. Then the waterproof motor 424 in the other net support assembly 4 is started to work, so that the other two net support rods 402 are rotated to the other two corners of the inside of the fish breeding net 201. The net support rod 402 is arranged in an L shape, and the four net support rods 402 form four support opening points, and the fish breeding net 201 is supported to be opened into a square shape under the action of the four force points. The external water injection equipment is started, water is transported into the water injection pipe 419 through the hose, and the water is uniformly transported into the two water outlet pipes 421 under the equalizing action of the flow equalizing pipe 418, and then enters the inside of the net support rod 402 through the connecting pipe 423, and then the water enters the inside of the weight increasing box 403 through the water inlet pipe 406, and flows to the sodium alginate 404 along the arc-shaped flow dividing plate 405. During the water injection process, the water quantity is monitored by the flow meter 420, and when the flow reaches the set pre-value, the water injection equipment is turned off. The sodium alginate 404 has a certain water absorption, and 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, and ensuring that the net clothes always maintain a good opening state. Through the reverse rotation of the waterproof motor 424, the net support rod 402 and the weight increasing box 403 are reversely rotated and turned out of the fish breeding net 201, and the initial state is restored. Then the net support rod 402 is taken off from the outer surface of the turnover rod 401, then the bolt between the connecting ring 417 and the fixed strip 416 is taken off, finally the weight increasing box 403 is taken off 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 taken off alone. Then the half-threaded rod 410 is rotated to screw out of the fixed block 409, and at the same time, the T-shaped sealing sleeve 412 is driven away from the sealing hole 414, the sealing plate 411 is taken off from the side of the weight increasing box 403, and the arc-shaped flow dividing plate 405 is pulled out of the inside of the weight increasing box 403, so that the gel-like sodium alginate 404 in the weight increasing box 403 can be poured out and fed to the fry as feed.The floating hook 305 on the side of the second floating block 302 is hooked in the shackle 304 on the side of the first floating block 301, the connection of the first floating block 301 and the second floating block 302 is completed, the above assembly process is repeated, the 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 insertion slot 306, the gap between the first floating block 301 and the second floating block 302 is filled by the floating compensation plate 303. The floating compensation strip 6 is inserted into the first connecting sliding slot 5 and the second connecting sliding slot 7, and the gap between the walking floating platform 1 and the assembled floating platform 3 is filled.
