Description

Technical Field

[0001] This invention relates to the field of fishery water conservancy and hydropower engineering technology, specifically to a floating fish collection device and fish collection system for water conservancy and hydropower engineering. Background Technology

[0002] In water conservancy and hydropower projects, fish are affected by the obstruction of dams, and it is necessary to help fish move from the reservoir area downstream to the river section below the dam or from the river section below the dam upstream to the reservoir area above the dam. Floating fish collection devices can be deployed simultaneously in multiple fish habitats in the reservoir area. Fish are attracted by lights and bait, and staff can then observe the number of fish collected through cameras to decide whether to proceed with the collection, thereby improving fish collection efficiency and maintaining gene exchange and genetic diversity in fish populations.

[0003] The floating fish-attracting device mainly consists of an above-water float and an underwater fish-attracting structure. The above-water float mainly functions to provide buoyancy, carry equipment, and serve as a visual marker. It powers the electronic equipment through solar panels. The underwater fish-attracting structure is mainly used to attract fish to gather, using lights and bait to draw the fish into the net cage.

[0004] Current floating fish-attracting devices typically simply place bait and a fish-attracting light inside the device and periodically add bait. When there is a lot of bait, it is easy for it to clump together or quickly disperse and sink to the bottom. This not only wastes the bait but also pollutes the water. At the same time, the static bait and light not only reduce the range of fish to be attracted but also increase the fish's wariness, affecting the device's fish-attracting effect. Summary of the Invention

[0005] This invention provides a floating fish-attracting device and system for water conservancy and hydropower projects. Through a fish-attracting mechanism and a feeding component, the bait can be driven to rotate evenly within the net cage, and released slowly while rotating. This not only allows for more even bait distribution but also reduces bait waste and water pollution. Furthermore, through a linkage mechanism and fish-attracting component, the dynamic positions of the fish-attracting light and bait can be adjusted to simulate food and light sources in the natural environment, reducing fish wariness and thus improving fish attraction efficiency and retention rate. This solves the problems mentioned in the background art, such as uneven bait distribution, waste, small trapping range, and poor fish-attracting effect.

[0016] Compared with the prior art, the present invention provides a floating fish-collecting device and fish-collecting system for water conservancy and hydropower projects, which has the following beneficial effects: 1. In this floating fish-attracting device used in water conservancy and hydropower projects, the fish-attracting mechanism can drive the bait bag to rotate evenly in the net cage, and the feeding component can slowly release the bait in the net cage. At the same time, when there are many fish, the amount of bait can be increased, which can not only make the bait spread more evenly and wider, but also reduce the waste of bait and reduce the pollution of the surrounding water body, thereby improving the attraction rate and retention rate of fish.

[0017] 2. In this floating fish-attracting device used in water conservancy and hydropower projects, the linkage mechanism can drive the fish-attracting lamp to rotate evenly around the net cage, and the angle of the fish-attracting lamp can be adjusted intermittently during rotation.

[0018] 3. In this floating fish-attracting device used in water conservancy and hydropower projects, air can be intermittently supplied to the feeding trough by adjusting the angle of the fish-attracting light, and then released into the water through the feeding bag. On the one hand, this can avoid clogging when the feed is released, and on the other hand, it can increase the oxygen content in the water in the net cage. At the same time, it can also improve the diffusion effect of the feed, which is conducive to the long-term survival of fish.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: Reference Figures 1-8 A floating fish-collecting device for water conservancy and hydropower projects includes a floating platform 1 and a net cage 2, which is fixedly connected to the bottom of the floating platform 1. A support frame 3 connected to the net cage 2 is fixedly connected to the bottom of the floating platform 1. The net cage 2 has multiple sets of fish inlets 4. A fish-attracting mechanism is set on the floating platform 1. A feeding component 12 is set on the side of the fish-attracting mechanism near the net cage 2. A bait bag 13 is connected to the feeding component 12. The fish-attracting mechanism drives the bait bag 13 to rotate evenly inside the net cage 2 through the feeding component 12. An inner toothed ring 18 is set on the outer wall of the floating platform 1. A linkage mechanism connected to the inner toothed ring 18 is set on the floating platform 1. A fish-collecting component 23 is set on the side of the inner toothed ring 18 near the net cage 2. The linkage mechanism is used to drive the fish-collecting component 23 to rotate evenly along the outer wall of the net cage 2. A bottom plate 5 is detachably connected to the bottom of the net cage 2 for collecting fish inside the net cage 2.

[0025] In this embodiment, a vision system is also installed on the floating platform 1 to observe the number of fish in the net cage 2. A solar panel can also be installed on the floating platform 1 to power the electrical equipment. When attracting fish, the equipment is placed at a designated location in the water area. Then, the fish-attracting mechanism drives the bait bag 13 to rotate slowly and evenly inside the net cage 2. During rotation, the feeding component 12 slowly releases bait, improving bait diffusion while reducing waste. Simultaneously, the linkage mechanism drives the fish-attracting lamp 233 to rotate slowly and evenly outside the net cage 2. During rotation, the angle of the fish-attracting lamp 233 is adjusted to simulate the dynamic changes of light sources in the natural environment, increasing the fish-attracting range. Furthermore, by adjusting the angle of the fish-attracting lamp 233, air can be intermittently supplied to the bait bag 13 to prevent bait blockage, improve bait diffusion, increase the oxygen content of the surrounding water, and enhance the fish attraction and retention rate.

[0026] Reference Figure 1 , Figure 4 and Figure 5 The fish-attracting mechanism includes a drive motor 7 fixedly connected inside the floating platform 1. A mounting groove 6 is provided on the side of the floating platform 1 near the drive motor 7. A central gear 8 connected to the output end of the drive motor 7 is rotatably connected inside the mounting groove 6. A planetary gear 9 meshing with the central gear 8 is rotatably connected inside the mounting groove 6. A double-sided gear ring 10 meshing with the planetary gear 9 is rotatably connected inside the floating platform 1. A bait trough 11 is provided on the side of the floating platform 1 near the double-sided gear ring 10. A feeding component 12 is located at the bottom of the double-sided gear ring 10. The bait trough 11 is arranged in a ring shape and is located above the feeding component 12. An addition port is provided on the bait trough 11, and the addition port is sealed.

[0027] In this embodiment, the drive motor 7 is started to drive the central gear 8 to rotate, and the planetary gear 9 drives the double-sided gear ring 10 to rotate, so that the feed bag 13 is slowly and evenly rotated in the net box 2 through the feeding assembly 12. The surface of the feed bag 13 is provided with uniform holes for slowly releasing the feed into the water, thereby increasing the diffusion range of the feed.

[0028] Reference Figure 4 , Figure 7 and Figure 8The feeding assembly 12 includes a fixed tube 121 fixedly connected to the bottom of the double-sided toothed ring 10. A groove 122 is formed at the bottom of the fixed tube 121. A first spring 123 is fixedly connected inside the groove 122. A movable tube 124, slidably connected to the end of the first spring 123, is fixedly connected to the end of the movable tube 124 away from the fixed tube 121. The bait bag 13 is fixedly connected to the end of the movable tube 124 away from the fixed tube 121. The bait bag 13 communicates with both the movable tube 124 and the fixed tube 121. The double-sided toothed ring 10 is located near... A bait adjustment component is provided on the side near the fixed tube 121 for adjusting the amount of bait in the bait bag 13. The bait adjustment component includes a connecting hole 126 on the double toothed ring 10 that communicates with the fixed tube 121. A sealing groove 127 is symmetrically provided on the side of the double toothed ring 10 near the connecting hole 126. A baffle 128 is slidably connected inside the sealing groove 127. A connecting channel 125 is provided inside the fixed tube 121 and the double toothed ring 10 that communicates with the sealing groove 127 and the groove 122.

[0029] In this embodiment, initially, the bait in the bait trough 11 will slowly fall into the bait bag 13 through the baffle 128 to prevent the bait from clumping in the water. As the number of fish in the net cage 2 increases, the fish will drag the bait bag 13, thereby driving the movable tube 124 to move downward in the groove 122 and move back to the initial position under the action of the first spring 123, thereby intermittently compressing the gas in the groove 122. The gas is transported to the interior of the sealing groove 127 through the connecting channel 125, thereby intermittently moving the two sets of baffles 128 relative to each other and towards each other. At this time, the amount of bait is increased to ensure the survival of fish in the net cage 2.

[0030] Reference Figures 1-4 The floating platform 1 has an annular groove 19 on the side near the internal toothed ring 18. A limit rod 20 is fixedly connected inside the internal toothed ring 18, and the limit rod 20 is slidably connected to the annular groove 19.

[0031] In this embodiment, under the action of the limiting rod 20 and the annular groove 19, the internal toothed ring 18 rotates stably along the outer wall of the floating platform 1.

[0032] Reference Figures 3-5 The linkage mechanism includes a connecting cavity 14 opened on the side of the floating platform 1 near the double-sided gear ring 10. The inside of the connecting cavity 14 is rotatably connected to a first gear 15 that meshes with the double-sided gear ring 10. The outer wall of the floating platform 1 is rotatably connected to a second gear 17 that meshes with an inner gear ring 18. A linkage member 16 is provided between the shaft ends of the first gear 15 and the second gear 17. The linkage member 16 includes a linkage wheel and a belt.

[0033] In this embodiment, when the double-sided toothed ring 10 rotates, it drives the first gear 15 to rotate, which in turn drives the second gear 17 to rotate via the linkage 16. This causes the inner toothed ring 18 to rotate slowly and evenly along the outer side of the floating platform 1, and drives the fish-attracting light 233 to rotate synchronously. It should be explained that the range and speed of bait diffusion are limited, making it difficult to attract fish schools at a relatively long distance. When attracting fish, the external fish-attracting light 233 can attract fish schools at a long distance. When the fish school approaches the net cage 2, it will be attracted by the bait, thus completing the fish attraction. In addition, the fish-attracting light 233 located inside the net cage 2 will affect the propagation of light.

[0034] Reference Figure 1 , Figure 3 , Figure 4 and Figure 6 The fish-attracting assembly 23 includes a fixing plate 231 fixedly connected to the bottom of the inner toothed ring 18. A hinge seat 232 is fixedly connected to the side of the fixing plate 231 away from the net cage 2. A fish-attracting lamp 233 is rotatably connected to the hinge seat 232. A push rod 234 that slidably engages with the fish-attracting lamp 233 is slidably connected to the fixing plate 231. A second spring 235 is fixedly connected between the fixing plate 231 and the fish-attracting lamp 233. A rod that engages with the fish-attracting lamp 233 is also fixedly connected to the fixing plate 231. The compression cylinder 236 is fitted together, wherein the second spring 235 is sleeved on the push rod 234, and the push rod 234 and the compression cylinder 236 are located symmetrically on the fixed plate 231. It also includes a guide wheel 21 rotatably connected to the inner wall of the inner gear ring 18 near the fixed plate 231. The guide wheel 21 is tightly fitted to the outer wall of the float 1. An eccentric wheel 22 is fixedly connected to the shaft end of the guide wheel 21. The eccentric wheel 22 is tightly fitted to the end of the push rod 234 away from the fish-attracting lamp 233.

[0035] In this embodiment, when the internal gear ring 18 rotates, it drives the fish-attracting lamp 233 to rotate synchronously through the fixing plate 231. At the same time, when the internal gear ring 18 rotates, it drives the guide wheel 21 to rotate along the surface of the floating platform 1, and through the eccentric wheel 22, it drives the push rod 234 to be pressed intermittently to one side of the fish-attracting lamp 233, thereby driving the upper end of the fish-attracting lamp 233 to rotate downward. Then, under the action of the second spring 235, it rotates back to the initial position, thereby intermittently adjusting the angle of the fish-attracting lamp 233, further increasing the illumination range of the fish-attracting lamp 233. The dynamic adjustment of the position of the fish-attracting lamp 233 allows the "signal coverage area" to accurately match the real-time distribution of fish, while simulating the dynamic changes of light sources in the natural environment, reducing the fish's vigilance, thereby improving the attraction efficiency and retention rate.

[0036] Reference Figure 1 , Figure 4 and Figure 6The top of the floating platform 1 is provided with an air slip ring 24. The interior of the floating platform 1 is provided with a channel that connects the air slip ring 24 and the bait trough 11. The air slip ring 24 is provided with an air inlet. The air inlet end of the compressed cylinder 236 extends to the liquid surface through a pipe. The exhaust end of the compressed cylinder 236 is connected to the air inlet of the air slip ring 24 through a pipe.

[0037] In this embodiment, during the angle adjustment of the fish-attracting lamp 233, the compression cylinder 236 can be intermittently squeezed. It should be explained that the compression cylinder 236 adopts an elastic structure or a spring is set inside the compression cylinder 236. When the compression cylinder 236 is in the compression state, the air inside it will be transported to the bait trough 11 through the air slip ring 24. As the air pressure in the bait trough 11 increases, the gas will enter the fixed pipe 121 and the movable pipe 124 through the connecting hole 126, and finally be released into the water through the bait trough 11. This not only avoids the blockage of the stable bait in the fixed pipe 121 and the movable pipe 124, but also increases the oxygen content of the water near the net cage 2 and improves the diffusion effect of the bait. When the compression cylinder 236 is in the extended state, it can extract the air above the water.

[0038] In this invention, when collecting fish, the equipment is placed at a designated location in the water area. Then, the drive motor 7 is started to drive the central gear 8 to rotate, which in turn drives the double-sided gear ring 10 to rotate through the planetary gear 9. This causes the feed assembly 12 to slowly and evenly rotate the feed bag 13 inside the net cage 2. The feed in the feed trough 11 will slowly fall into the feed bag 13 through the baffle 128, preventing the feed from clumping in the water. As the number of fish in the net cage 2 increases, the fish will drag the feed bag 13, thereby driving the movable tube 124 to move downward in the groove 122 and move back to the initial position under the action of the first spring 123. The gas in the groove 122 is transported to the interior of the sealing groove 127 through the connecting channel 125. This causes the two sets of baffles 128 to move intermittently relative to each other and towards each other to increase the amount of feed and ensure the fish remain in the net cage 2. Simultaneously, the double-sided gear rings 10 drive the first gear 15 to rotate, which in turn drives the second gear 17 to rotate via the linkage 16. This causes the inner gear ring 18 to rotate slowly and evenly along the outer side of the floating platform 1, causing the fish-attracting lamp 233 to rotate synchronously. In addition, the inner gear ring 18 drives the guide wheel 21 to rotate along the surface of the floating platform 1, and through the eccentric wheel 22, it intermittently presses the push rod 234 towards one side of the fish-attracting lamp 233, thereby causing the upper end of the fish-attracting lamp 233 to rotate downwards. Then, under the action of the second spring 235, it rotates back to the initial position, thus intermittently adjusting the angle of the fish-attracting lamp 233, further increasing the illumination range of the fish-attracting lamp 233, simulating a natural ring. The dynamic changes in the ambient light reduce the fish's alertness, thereby improving attraction efficiency and retention rate. During the angle adjustment of the fish-attracting lamp 233, the cylinder 236 is intermittently compressed, and the air inside is transported to the feed trough 11 through the air slip ring 24. As the air pressure in the feed trough 11 increases, the gas will enter the fixed pipe 121 and the movable pipe 124 through the connecting hole 126, and finally be released into the water through the feed trough 11. This not only avoids the blockage of the stable feed in the fixed pipe 121 and the movable pipe 124, but also increases the oxygen content of the water near the net cage 2, and improves the diffusion effect of the feed.

[0039] Example 2: A floating fish collection system for water conservancy and hydropower projects includes the following steps: Step 1: After the equipment is assembled, place it in the designated location in the water area to collect fish; Step Two: During the fish-gathering process, first, slowly release the bait and move it slowly to accelerate its spread; Step 3: When a large number of fish gather, the amount of bait will be automatically increased; Step 4: At the same time, slowly move the lights around the equipment to attract fish, and adjust the angle of the lights during the process to simulate a natural scene and expand the fish-attracting area. Step 5: While adjusting the light angle, intermittently replenish air through the bait area to increase the oxygen content of the water.
