Description

Technical Field

[0001] This invention belongs to the field of aquatic ecological restoration technology, specifically relating to a ring-shaped structure device that increases the drifting process of fish eggs. Background Technology

[0002] In natural rivers, drifting fish eggs require a certain amount of time to develop and hatch. Given a fixed development time and water flow velocity, sufficient drifting flow is necessary to prevent the eggs from sinking to the bottom before hatching. However, the construction of cascade reservoirs fragments rivers into discontinuous, segmented habitats such as river-lake-river, leading to unmet conditions in water flow velocity and drifting flow. This negatively impacts the hatching of drifting fish eggs, resulting in insufficient replenishment of drifting egg-laying fish and significantly affecting overall resource levels. Existing restoration measures, including ecological regulation, only stimulate spawning behavior and do not solve the aforementioned problems. Stocking also suffers from low survival rates. Therefore, a ring-shaped structure can be designed to increase the drifting flow. During the fish breeding season, artificially increasing the drifting flow can address the critical "still water trap" problem in cascade reservoirs, replacing fragmented river channels with a closed-loop track to maintain the continuous flow required for fish egg development.

[0003] Chinese invention patent application number CN202310338593.1 discloses a comprehensive system for hatching drifting fish eggs, including a culture tank, a flow rate control system, an island-type real-time monitoring system, a tiered fish egg transfer system, a fish egg release system, a fish egg collection system, a tailwater collection platform, and a water storage tank. This invention overcomes the influence of single-factor conditions on hatching, achieving adjustability of influencing factors under different hatching environments, real-time tracking of the entire fish egg hatching process, and simulation of natural water flow conditions. During the hatching process, it eliminates the cumbersome operation of multiple manual releases of fish eggs as in previous patents, achieving a one-time release of fish eggs with fully automated operation, thus improving the hatching rate. Simultaneously, to identify the drifting path patterns of fish eggs during hatching, it sets up side-view and top-view fish egg drift monitoring systems and a hydraulic characteristic testing system. Furthermore, the fish egg hatching drift distance statistically analyzed by the monitoring system can provide a reference for the fish species richness of the main stream and tributaries of a river section.

[0004] However, current methods for hatching drifting eggs are mostly limited to field collection, monitoring, indoor hatching, and observation. These methods require real-time human observation and adjustment of drifting time and distance, and lack devices for restoring the drifting process of drifting fish eggs in wild river channels. Furthermore, existing drifting fish egg hatching equipment often uses propeller rotation or multiple nozzles at the bottom of a circular channel to spray water, driving the water flow and circulating it to propel the eggs. This method causes the eggs to tumble in the water, and the water flow is chaotic; the water does not flow uniformly across the entire cross-section, failing to guarantee uniform flow throughout. This deviates significantly from the actual overall water flow conditions under natural circumstances, negatively impacting the hatching effect. Moreover, during the circulating drifting process, because the same drifting channel is shared, the eggs within the channel are prone to backflow, affecting the hatching outcome. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a ring-shaped structure device that enhances the drifting process of fish eggs. Through the coordinated operation of a drifting track, a propulsion component, a one-way blocking component, and a motor component, this invention better simulates and replicates the drifting of fish eggs in a natural river. This results in a more stable and uniform water flow, artificially adding a drifting process and creating a more natural hatching environment for the fish eggs, thus increasing the hatching rate. Furthermore, this invention includes an anti-backward mechanism to ensure that the fish eggs are only propelled forward, achieving a continuous forward drifting simulation. Moreover, gate components are fixedly connected to the two connecting points of the egg drifting channel and the inlet and outlet channels, respectively. Therefore, by controlling the opening and closing of the two gates at the front and rear ends and the timing, the fish eggs can be fed into the drifting track, and the drifting time and distance can be controlled and adjusted.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A ring-shaped structure device for enhancing the drifting process of fish eggs is characterized by comprising a drifting track, multiple propulsion components arranged on the drifting track, and an egg-drifting channel enclosed by an inner side plate, an outer side plate, and a bottom plate in the drifting track. An inlet channel and an outlet channel, respectively, connected to the egg-drifting channel are fixedly connected to the front and rear ends of the drifting track. Each propulsion component includes a push plate rotatably connected to a sliding plate, which is slidably connected to a first chute of the drifting track. The end of the push plate away from the sliding plate faces into the egg-drifting channel, and a limiting post is fixedly connected to the bottom of the push plate, located on the back side of the push plate. The propulsion component is driven by a motor assembly, which is configured to push the propulsion component to move back and forth linearly along the first chute when the motor assembly is activated. The inner wall of the rafting track is provided with an installation groove, and a one-way blocking component is placed in the installation groove. The one-way blocking component is configured such that when the push plate passes in the direction of water flow, the one-way blocking component is pushed into the installation groove, and when the push plate passes in the direction of water flow, the one-way blocking component blocks the push plate.

[0007] Furthermore, the one-way blocking assembly includes a stop block, one side of which is rotatably connected to a rotating shaft, the rotating shaft being fixedly connected to a mounting groove, the other side of which is partially accommodated in the egg-floating channel, a spring being fixedly connected to the side of the stop block away from the egg-floating channel, and the end of the spring away from the stop block being fixedly connected to the inner wall of the mounting groove.

[0008] Furthermore, mounting grooves are provided on the inner walls of both the inner and outer side panels, with the mounting grooves on the inner side panel and the mounting grooves on the outer side panel arranged in a double opposite arrangement.

[0009] Furthermore, the propulsion assembly includes two sliders, which are respectively fixedly connected to the lower parts of both ends of the slide plate, and the sliders are slidably embedded in corresponding first slide grooves. Multiple first slide grooves are respectively fixedly connected to the upper outer walls of the inner and outer side plates.

[0010] Furthermore, the propulsion assembly includes a rotating rod rotatably connected to a slide plate, with the rotating rod sleeved at one end of a push plate. The plane of rotation of the push plate around the rotating rod is parallel to the adjacent inner and outer side plates.

[0011] Furthermore, the propulsion assembly includes a connecting seat, which is fixedly connected to the push plate. One end of the first connecting rod is hinged to the connecting seat, and the other end of the first connecting rod is rotatably connected to one end of the second connecting rod. The other end of the second connecting rod is drive-connected to the motor assembly.

[0012] Furthermore, the motor assembly includes a motor fixed to one end of a motor bracket, with the other end of the motor bracket, away from the motor, fixed to the ground. The output end of the motor is drively connected to the other end of the second link, which rotates about the output end of the motor.

[0013] Furthermore, gate assemblies are fixedly connected to the two connecting ports of the egg-drifting channel and the inlet and outlet channels, respectively. The gate assembly includes a gate frame, a protrusion on the upper side of the gate is embedded in the second sliding groove on the inner side of the gate frame, a screw passes through the top of the gate frame and the gate and is driven by the gate, a gate motor is fixed on the top of the gate frame and is driven by the screw, and a controller is fixed on the top of the gate frame and is electrically connected to the gate motor.

[0014] Furthermore, the limiting post has at least two, and each limiting post is fixedly connected to the lower part of the slide plate at intervals. The limiting post is accommodated in the floating egg channel, and the limiting post is opposite to the back of the push plate.

[0015] Furthermore, the push plate is arc-shaped, with a concave front and a convex back.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) This invention can better replicate the drifting of fish eggs in natural rivers and improve the hatching rate of fish eggs. In this invention, the drifting channel is ring-shaped, which allows the fish eggs placed in the channel to drift in a cycle with the water flow. It can provide sufficient drifting flow during the hatching process of fish eggs. Four sets of propulsion components are arranged on the drifting track to propel the water flow in the drifting channel to circulate. The slide can slide above the drifting channel along the length of the first chute. Since the push plate is rotatably connected to the slide plate through the rotating rod, and the bottom of the slide plate is fixedly connected to two limiting posts that are accommodated in the drifting channel, the limiting posts are located on the back of the push plate. Therefore, when the motor assembly pushes the slide plate of the propulsion component to move, the push plate rotates backward under the water pressure until it abuts against the limiting post. After the rotation of the push plate is restricted by the limiting post, it is consistent with the movement of the slide plate. The push plate pushes the water in the drifting channel to flow forward as a whole, and at the same time, it drives the fish eggs in the water flow to drift in the drifting channel. When the motor is started, it can drive the propulsion component to move back and forth on the first chute. Furthermore, a one-way blocking component is installed in the mounting groove on the inner wall of the rafting track. This component is configured such that when the pusher plate passes in the direction of the water flow, it retracts into the mounting groove; when the pusher plate passes against the water flow, it blocks the pusher plate. When the pusher plate is pulled backward, it comes into contact with the one-way blocking component. At this point, the slide continues to move backward, and the pusher plate begins to rotate around the rotating rod and separate from the limiting post. The slide continues to move backward until the end of the pusher plate that is furthest from the slide has passed the stop, at which point the pusher plate falls around the rotating rod. Next, the skateboard changes direction again, moving forward and pushing the pusher plate. Under water pressure, the pusher plate rotates backward until it hits the limiting post. Once the rotation of the pusher plate is restricted by the limiting post, it moves in sync with the movement of the skateboard. The pusher plate then pushes the water in the egg-drifting channel forward, repeating this cycle. This ensures that the water flows forward in the same direction, guaranteeing that the entire cross-section flows together. The water flow is more stable and uniform, and the egg-drifting and hatching environment is closer to the water flow in a natural river.

[0017] (2) This invention can be directly placed in the wild for the incubation of drifting eggs. It can automatically control the drifting time and drifting distance without human monitoring of the incubation situation in real time, and complete the ingestion of eggs and release of fish. Because the two connecting ports of the drifting egg channel and the inlet and outlet channels are respectively fixedly connected to gate components, the gate components can be driven to move up and down along the height direction of the gate frame by starting the gate motor. Moreover, the controller is electrically connected to the gate motor, which can not only control the rotation direction and angle of the gate motor, but also control the start interval of the two gate motors. Therefore, by controlling the opening and closing sequence and time of the two gate components at the connecting ports of the inlet and outlet channels and the drifting egg channel, in addition to introducing fish eggs from the river into the drifting track and releasing fish eggs hatched in the drifting track out of the drifting track, the drifting time and drifting distance can also be adjusted according to the time required for different fish to drift and hatch.

[0018] (3) The present invention also has an anti-backward mechanism. In the present invention, because the push plate is rotatably connected to the slide plate through the rotating rod, and the bottom of the slide plate is fixedly connected to two limiting posts that are housed in the floating egg channel, the limiting posts are located on the back of the push plate. When the motor assembly pushes the slide plate of the propulsion assembly to move, the push plate rotates backward under the action of water pressure until it abuts against the limiting posts. The push plate blocks most of the cross-sectional area of ​​the floating egg channel. The push plate pushes the water in the floating egg channel to flow forward as a whole, and at the same time drives the fish eggs in the water flow to float in the floating channel. At this time, the floating egg channel is blocked in the backward direction by the push plate. Moreover, four propulsion components are installed on one floating egg channel. The forward and backward movements of the four propulsion components are not consistent, so that there is always a push plate in the floating egg channel that is blocked, thereby ensuring that the fish eggs are only pushed forward and not backward, realizing the simulation of floating forward continuously.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. Of course, the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0022] Although the steps in this invention are arranged by reference numerals, this is not intended to limit the order of the steps. Unless the order of the steps is explicitly stated or the execution of a step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" as used herein refers to and covers any and all possible combinations of one or more of the associated listed items.

[0023] Example like Figures 1-8As shown, a ring-shaped structure device for increasing the drifting process of fish eggs is characterized by including a drifting track 100, with multiple propulsion components 200 arranged on the drifting track 100. The space enclosed by the inner side plate 101, the outer side plate 102, and the bottom plate 103 in the drifting track 100 forms an egg drifting channel 104. Each propulsion component 200 includes a pusher plate 201, which is rotatably connected to a slide plate 202. The slide plate 202 is slidably connected to a first groove 105 of the drifting track 100. The end of the pusher plate 201 away from the slide plate 202 faces inward into the egg drifting channel 104. A limiting post 205 is fixedly connected to the bottom of the pusher plate 201, located on the back side of the pusher plate 201. The propulsion component 200 is driven by a motor assembly 400, which is configured such that when the motor assembly 400 is started, it pushes the propulsion component 200 to move back and forth linearly along the first groove 105. The inner wall of the rafting track 100 is provided with an installation groove 106, and a one-way blocking component 300 is placed in the installation groove 106. The one-way blocking component 300 is configured such that when the push plate 201 passes in the direction of water flow, the one-way blocking component 300 is pushed into the installation groove 106, and when the push plate 201 passes in the direction of water flow, the one-way blocking component 300 blocks the push plate 201.

[0024] In this invention, the drifting track 100 includes an inner side plate 101, an outer side plate 102, and a bottom plate 103. The space enclosed by the inner side plate 101, the outer side plate 102, and the bottom plate 103 is a drifting egg channel 104 for water flow and fish eggs to drift. The drifting egg channel 104 is annular, allowing the fish eggs placed in the channel to circulate with the water flow, providing sufficient drifting flow during the hatching process. Four sets of propulsion components 200 are arranged on the drifting track 100 to propel the water flow in the drifting egg channel 104 for circulation. The bottom of the slide plate 202 on the propulsion component 200 is fixedly connected to a slider 204. The slider 204 is slidably embedded in the corresponding first groove 105 on the drifting track 100, so that the slide plate 202 can move along the first groove 105. A chute 105 slides along its length above the egg-floating channel 104. Since the push plate 201 is rotatably connected to the slide plate 202 via the rotating rod 203, and the bottom of the slide plate 202 is fixedly connected to two limiting posts 205 that are housed in the egg-floating channel 104, with the limiting posts 205 located on the back of the push plate 201, when the motor assembly 400 pushes the slide plate 202 of the propulsion assembly 200 to move, the push plate 201 rotates backward under water pressure until it abuts against the limiting posts 205. After the rotation of the push plate 201 is restricted by the limiting posts 205, it moves in the same direction as the slide plate 202. The push plate 201 pushes the water in the egg-floating channel 104 to flow forward as a whole, while simultaneously causing the fish eggs in the water to float in the drifting channel 104.Furthermore, because one end of the first connecting rod 207 is hinged to the connecting seat 206 fixed on the slide plate 202, and the other end of the first connecting rod 207 is rotatably connected to one end of the second connecting rod 208, and the other end of the second connecting rod 208 is drively connected to the output end of the motor 401 fixed on the motor bracket 402, when the motor 401 is started, it can drive the propulsion assembly 200 to move back and forth on the first slide 105. Moreover, a one-way blocking assembly is installed in the mounting groove 106 on the inner wall of the rafting track 100. 300, the one-way blocking component 300 is configured such that when the push plate 201 passes in the direction of water flow, the one-way blocking component 300 is pushed back into the mounting groove 106; when the push plate 201 passes in the direction of water flow, the one-way blocking component 300 blocks the push plate 201. Therefore, when the push plate 201 is pushed to its furthest point in the forward direction, it begins to be pulled backward. When the push plate 201 is pulled backward, it comes into contact with the one-way blocking component 300. At this time, the slide plate 202 continues to move backward, and the push plate 201 begins to rotate around the rotating rod 203. The push plate 201 rotates and separates from the limiting post 205 until it rotates outside the egg-floating channel 104. The slide plate 202 continues to move backward until the end of the push plate 201 away from the slide plate 202 passes the stop 301. Then, the push plate 201 falls around the rotating rod 203. The slide plate 202 changes its direction of movement again, moving forward and pushing the push plate 201. The push plate 201 rotates backward under water pressure until it abuts against the limiting post 205. After the rotation of the push plate 201 is restricted by the limiting post 205, it moves in conjunction with the movement of the slide plate 202. To maintain consistency, the pusher plate 201 again propels the water in the egg-drifting channel 104 forward, repeating this cycle to ensure the water flows in the same direction across the entire cross-section. This results in a more stable and uniform water flow, creating an environment for fish eggs to drift and hatch more closely resembling the flow conditions of a natural river. This innovative design of a ring-shaped structure simulating natural river conditions, applied to cascade-developed rivers, addresses the problem of insufficient drifting of fish eggs.

[0025] It is worth noting that the direction of water flow is forward, and the opposite direction of water flow is backward. Moreover, the side of the limiting post 205 facing backward has a chamfer, and the side of the limiting post 205 facing backward has a relatively sharp bevel. This allows the limiting post 205 located in the egg-drifting channel 104 to reduce the resistance of the water flow when the propulsion assembly 200 moves backward.

[0026] Furthermore, the one-way blocking assembly 300 includes a stop block 301. One side of the stop block 301 is rotatably connected to a rotating shaft 302, and the rotating shaft 302 is fixedly connected to the mounting groove 106. The other side of the stop block 301 is partially accommodated in the egg-floating channel 104. A spring 303 is fixedly connected to the side of the stop block 301 away from the egg-floating channel 104. The end of the spring 303 away from the stop block 301 is fixedly connected to the inner wall of the mounting groove 106.

[0027] In this invention, when the push plate 201 passes the one-way blocking component 300 in the direction of water flow, the push plate 201 pushes the stop block 301 in the forward direction. The stop block 301 rotates around the rotating shaft 302 toward the inside of the mounting groove 106, the spring 303 is compressed and contracts, and the stop block 301 is pushed into the mounting groove 106. After the push plate 201 passes the one-way blocking component 300, the spring 303 extends and pushes the stop block 301 out into the egg-floating channel 104. Then, when the push plate 201 passes the one-way blocking component 300 in the direction of water flow, the push plate 201 pushes the stop block 301 backward. When the stop block 301 rotates backward, it is blocked by the stop post 304. At this time, the slide plate 202 continues to move backward, and the push plate 201... The push plate 201 begins to rotate around the rotating rod 203 and separates from the limiting post 205 until it rotates to the outside of the egg-floating channel 104. The slide plate 202 continues to move backward until the end of the push plate 201 away from the slide plate 202 passes the stop 301. Then, the push plate 201 falls around the rotating rod 203, and the slide plate 202 changes its direction of movement again, moving forward and pushing the push plate 201. The push plate 201 rotates backward under the action of water pressure until it abuts against the limiting post 205. After the rotation of the push plate 201 is restricted by the limiting post 205, it moves in the same direction as the slide plate 202. The push plate 201 once again pushes the water in the egg-floating channel 104 forward, thus providing power for the water circulation.

[0028] Furthermore, both the inner side plate 101 and the outer side plate 102 have mounting grooves 106 on their inner walls, and the mounting grooves 106 on the inner side plate 101 and the mounting grooves 106 on the outer side plate 102 are arranged in pairs opposite to each other.

[0029] Furthermore, the propulsion assembly 200 includes two sliders 204, which are respectively fixedly connected to the lower parts of both ends of the slide plate 202. The sliders 204 are slidably embedded in corresponding first slide grooves 105. Multiple first slide grooves 105 are respectively fixedly connected to the upper part of the outer wall of the inner side plate 101 and the outer side plate 102.

[0030] Furthermore, the propulsion assembly 200 includes a rotating rod 203, which is rotatably connected to the slide plate 202 and sleeved on one end of the push plate 201. The plane of rotation of the push plate 201 around the rotating rod 203 is parallel to the adjacent inner side plate 101 and outer side plate 102.

[0031] In this invention, because the push plate 201 is rotatably connected to the slide plate 202 via the rotating rod 203, and the bottom of the slide plate 202 is fixedly connected to two limiting posts 205 that are accommodated in the egg-floating channel 104, with the limiting posts 205 located on the back of the push plate 201, when the motor assembly 400 pushes the slide plate 202 of the propulsion assembly 200 to move, the push plate 201 rotates backward under water pressure until it abuts against the limiting posts 205. The push plate 201 blocks most of the cross-sectional area of ​​the egg-floating channel 104. 1. The water in the egg-floating channel 104 is pushed forward as a whole, and the fish eggs in the water flow are driven to drift in the drifting channel 104. At this time, the backward direction of the egg-floating channel 104 is blocked by the push plate 201. Moreover, four push components 200 are installed on one egg-floating channel 104. The forward and backward movements of the four push components 200 are not synchronized, so that there is always a push plate 201 in the egg-floating channel 104 that is blocked. This ensures that the fish eggs are only pushed forward and not backward, realizing the simulation of drifting forward continuously.

[0032] Furthermore, the propulsion assembly 200 includes a connecting seat 206, which is fixedly connected to the push plate 201. One end of the first connecting rod 207 is hinged to the connecting seat 206, and the other end of the first connecting rod 207 is rotatably connected to one end of the second connecting rod 208. The other end of the second connecting rod 208 is drive-connected to the motor assembly 400.

[0033] Furthermore, the motor assembly 400 includes a motor 401, which is fixed to one end of a motor bracket 402, and the other end of the motor bracket 402, away from the motor 401, is fixed to the ground. The output end of the motor 401 is connected to the other end of the second connecting rod 208, and the second connecting rod 208 rotates around the output end of the motor 401.

[0034] It is worth noting that a bracket is installed at the position where the output end of the motor 401 is connected to the other end of the second link 208 to stabilize the rotation of the second link, so as to prevent the second link 208 from wobbling unstably when the motor 401 drives the second link 208 to rotate.

[0035] Furthermore, gate assemblies 500 are fixedly connected to the two connecting ports of the egg-drifting channel 104, the inlet channel 107, and the outlet channel 108, respectively. The gate assembly 500 includes a gate frame 501, a protrusion on the upper side of the gate 503 is embedded in the second sliding groove 502 inside the gate frame 501, a screw 504 passes through the top of the gate frame 501 and the gate 503 and is drivenly connected to the gate 503, a gate motor 505 is fixed to the top of the gate frame 501 and is drivenly connected to the screw 504, and a controller 506 is fixed to the top of the gate frame 501 and is electrically connected to the gate motor 505.

[0036] In this invention, the drifting time and drifting distance can be automatically controlled without real-time human monitoring of the hatching situation. It can be placed in the wild to automatically hatch drifting eggs, completing egg introduction and fish release. This is because gate assemblies 500 are fixedly connected to the two connecting points of the egg drifting channel 104, the inflow channel 107, and the outflow channel 108. By activating the gate motor 505, the gate 503 of the gate assembly 500 can be driven to move up and down along the height of the gate frame 501. Furthermore, the controller 506 is electrically connected to the gate motor 505, controlling not only the gate motor... The rotation direction and angle of 505 can also control the start interval of the two gate motors 505. Therefore, by controlling the opening and closing sequence and time of the two gate components 500 at the connection between the inflow channel 107 and the outflow channel 108 and the drifting egg channel 104, in addition to introducing fish eggs from the river into the drifting track 100 and releasing the fish eggs hatched in the drifting track 100 out of the drifting track 100, thus solving the most critical "still water trap" problem of the cascade reservoir, it can also adjust the drifting time and drifting distance according to the time required for different fish to drift and hatch.

[0037] It is worth noting that the end of the inlet channel 107 away from the rafting track 100 is connected to the upstream of the river, and the end of the outlet channel 108 away from the rafting track 100 is connected to the downstream of the river.

[0038] Optionally, the controller 506 is a DC motor forward and reverse controller, manufactured by Jinggu Electronics, with motor model HH7090CK1JEA.

[0039] Furthermore, there are at least two limiting posts 205, and each limiting post 205 is fixedly connected to the lower part of the slide plate 202 at intervals. The limiting posts 205 are housed in the egg-floating channel 104, and the limiting posts 205 are opposite to the back of the push plate 201.

[0040] Furthermore, the push plate 201 is arc-shaped, with a concave front and a convex back.

[0041] In this invention, because the front of the pusher plate 201 is concave, when the pusher plate 201 pushes water in the egg-floating channel 104 in the forward direction, it can make the water flow forward and upward, reducing the water flow forward and downward so that the fish eggs accumulate at the bottom of the egg-floating channel 104.

[0042] Furthermore, the length of the first groove 105 is greater than the length of the push plate 201.

[0043] In this invention, because the length of the first slide 105 is greater than the length of the push plate 201, it is possible to avoid the situation where the push plate 201 cannot fall off the stop 301 when the slide plate 202 moves backward to the maximum position.

[0044] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
