[0002] In order to deal with the damage to the ecology caused by dams, especially the impact of blocking migratory fish, a series of fishways have been built. However, the effect of fish passage in my country is not ideal at present. The main reason is that it is difficult for fish to find the entrance of the fishway, and the traditional fishway has a simple structure and is too long. Fish cannot swim out of the fishway at once, and there is no rest area for fish, which easily leads to confusion and blockage.

[0003] To this end, a Chinese patent with patent number CN205712014U discloses a bionic ecological fishway with water flow regulation and induction effects, including a dam body, a curved and uniformly upward bionic riverbed at the bottom of the inner cavity of the dam body, a water flow buffer zone at the lower side of the bend of the bionic riverbed, baffles are hinged at the bend of the bionic riverbed, the baffles provided upstream of the bionic riverbed are connected to the twisted wire shaft through cables, sound and light inducers are evenly provided on both sides of the bionic riverbed, infrared sensors are provided on both sides of the fishway entrance, a water flow sensor is provided at the bottom of the bionic riverbed, a fish food feeding device has an induction effect on the fish school, and it is convenient for the fish school to find the correct fishway entrance, the structure of the water flow buffer zone is adopted to allow the exhausted fish school to rest, and the fish food in the water flow replenishes the physical strength of the fish school, and the structure of the baffle, the twisted wire shaft and the gate adjustment device is adopted to adjust the flow rate of water in the bionic riverbed, so that the fish school can better pass through the fishway.

[0004] However, the feeding point of the feeding device is relatively fixed, which is not convenient for angle adjustment, and the fish food is concentrated and not easy to spread, which is not conducive to attracting fish schools to enter the fishway in a large range. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a bionic ecological fishway with adjustable water flow and induction effect. The water flow in the main body of the fishway can be flexibly adjusted through a gate mechanism and a diversion mechanism to adapt to the migration needs of different fish. Through the close cooperation of the diversion mechanism and the induction mechanism, the angle of the feeding box can be adjusted conveniently, and fish schools in a larger range can be attracted to enter the fishway. The pulse fish blocking electric fence can effectively block fish schools and ensure that fish schools enter the fishway according to a predetermined path, thereby improving the utilization efficiency of the fishway. It solves the problems in the prior art that the feeding point of the feeding device is relatively fixed, which makes it inconvenient to adjust the angle, and the fish food is concentrated and not easy to spread, which is not conducive to attracting fish schools into the fishway on a large scale.

[0006] The present invention is implemented as follows: a bionic ecological fishway with adjustable water flow and induction effect, including a dam body, two fishway guard plates are fixed on the dam body, a fishway main body is set between the fishway guard plates, an inlet plate is fixed to one end of the fishway main body, a gate mechanism for adjusting the water flow is installed at the other end of the fishway main body, a guide mechanism for adjusting the water flow is installed on the inner wall of the fishway guard plate, the guide mechanism includes an adjusting rod, a tunnel part is provided on the fishway main body, an induction mechanism for inducing fish schools is installed on the tunnel part, the induction mechanism includes a feeding box, the top of the adjusting rod can drive the feeding box to rotate, and a pulse fish blocking electric grid is installed at the inlet plate.

[0007] With this arrangement, the water flow in the main body of the fishway can be flexibly adjusted through the gate mechanism and the diversion mechanism to adapt to the migration needs of different fish species. The induction mechanism can play a role in attracting and inducing fish schools. Through the close cooperation of the diversion mechanism and the induction mechanism, the feeding box can be adjusted at a certain angle, which is conducive to expanding the feeding range of fish food, facilitating the attraction of fish schools in a larger range, increasing the probability of fish schools entering the fishway, and helping fish schools to pass through the fishway smoothly. In addition, the pulse fish blocking electric fence is set at the entrance of the fishway, which can effectively block the fish schools and ensure that the fish schools enter the fishway according to the predetermined path, thereby improving the use efficiency of the fishway. The overall design of the fishway simulates the ecological environment, is conducive to fish migration, and protects the ecological balance.

[0008] As a preferred embodiment of the present invention, the gate mechanism includes a gate plate, an installation groove is opened on the inner side of the fishway guard plate, a guide frame is fixed on the groove wall of the installation groove, the gate plate is slidably connected between the guide frames, the bottom of the installation groove is connected to a lifting screw through a bearing, the two ends of the gate plate are threadedly sleeved on the corresponding lifting screw, the top of the fishway guard plate is fixedly connected with a bracket, the top of the bracket is fixedly installed with a lifting motor, and the output end of the lifting motor is fixedly connected to the upper end of the lifting screw.

[0009] Through this arrangement, the stability of the gate installation is improved. Starting the lifting motor can drive the two lifting screws to rotate synchronously, and then it is convenient to drive the gate to move upward and downward, so as to open the gate wider and narrower, and to accurately adjust the water flow speed in the fishway; for some fish that adapt to slow water flow, the gate can be appropriately closed by moving the gate downward, which can reduce the water flow speed in the fishway and allow these fish to migrate smoothly in a relatively slow water flow environment. For some fish that adapt to strong water flow, the gate can be appropriately opened by moving the gate upward, thereby increasing the water flow speed to meet the fish's requirements for the water flow environment.

[0011] This arrangement improves the stability of the guide plate installation structure. The stepper motor is started to drive the traverse rod to rotate, and then the worm gear is driven to rotate, which in turn drives the adjustment rod and the guide plate to rotate, thereby realizing flexible adjustment of the guide plate rotation angle. By adjusting the angle between the guide plate and the fishway guard plate, different degrees of energy dissipation can be achieved to meet different flow velocity and flow state requirements. The close cooperation between the gate mechanism and the guide mechanism is conducive to the coordinated optimization of the water flow velocity distribution. When the gate opening is large and the water flow velocity becomes faster overall, the guide plate can direct part of the water flow to the edge or corner of the fishway body, reducing the water flow velocity in the central area, forming a combination of fast and slow water flow velocity distribution, so as to meet the different needs of different fish for water flow velocity in different positions.

[0014] As a preferred embodiment of the present invention, a tunnel roof is fixedly installed on the top of the tunnel part, a uniform white light source LED lamp is fixedly installed on the bottom of the tunnel roof, and the bottom of the tunnel roof is also connected to two support rods through bearings, and a half-toothed turntable and a gear ring are respectively fixed on the two support rods, the half-toothed turntable and the gear ring are meshingly connected, and the gear ring and the gear are meshingly connected.

[0015] Through this arrangement, the phototaxis characteristics of fish are utilized, and the white light source LED lamp is conducive to attracting and inducing fish to enter the bionic ecological fishway, which is convenient for stably installing the half-tooth turntable and the gear ring. Through the transmission principle of the gear ring and the gear, when the gear rotates, it is convenient to drive the gear ring and the half-tooth turntable to rotate, and it is convenient to drive the feeding box on the half-tooth turntable to adjust a certain angle, which is conducive to expanding the feeding range of fish food, facilitating the attraction of fish schools in a larger range, increasing the probability of fish schools entering the fishway, and helping fish schools to pass through the fishway smoothly.

[0017] Through this arrangement, it is convenient to install the feeding box, it is convenient to put fish food into the fishway body through the feeding tube, and it is convenient to control the opening and closing of the feeding tube through the electromagnetic valve, which is convenient to use.

[0018] As a preferred embodiment of the present invention, the pulse fish-blocking electric grid includes a pulse current generator and a stainless steel electrode tube, the pulse current generator and the stainless steel electrode tube are electrically connected via a wire, two cement piles are fixedly installed on the dam body, connecting rings are fixedly connected to the inner walls of the cement piles, fixing rings are sleeved on the connecting rings, steel strands are fixedly installed between the fixing rings, and a plurality of stainless steel electrode tubes are provided and are evenly distributed on the steel strands.

When the pulse current generator generates a pulse current under the drive of a power supply, the current is transmitted to the stainless steel electrode tubes through connecting wires. The stainless steel electrode tubes are arranged at intervals in the water. Since water is a conductor, when current passes between the stainless steel electrode tubes, a pulsed electric field is formed in the water, thereby achieving the effect of blocking and driving away fish, and ensuring that the fish enter the fishway according to the predetermined path.

[0021] This arrangement facilitates the stable installation of the stainless steel electrode tube, and the free tilting of the stainless steel electrode tube under the impact of the water flow, so that large floating objects in the water can slide smoothly through the stainless steel electrode tube. The stainless steel electrode tube can also automatically reset, which is easy to use and helps to avoid accidents caused by blockage or shielding of the pulse fish intercepting electric grid that affects its efficiency.

[0022] As a preferred embodiment of the present invention, a controller is fixedly installed in the middle of the bracket, and a water flow sensor is fixedly installed at the bottom of the fishway body.

[0030] By adopting the above scheme, the water flow in the fishway body 103 can be flexibly adjusted through the gate mechanism and the diversion mechanism to meet the migration needs of different fish. The induction mechanism plays a role in attracting and inducing fish. Through the close cooperation of the diversion mechanism and the induction mechanism, the feeding box 3 can be adjusted at a certain angle, which is beneficial to expand the feeding range of fish food, facilitate the attraction of fish in a larger range, increase the probability of fish entering the fishway, and help fish to pass through the fishway smoothly. In addition, the pulse fish blocking electric fence is set at the entrance of the fishway, which can effectively block the fish, ensure that the fish enters the fishway according to the predetermined path, and improve the use efficiency of the fishway. The overall design of the fishway simulates the ecological environment, is beneficial to fish migration, and protects the ecological balance.

[0031] Specifically, the gate mechanism includes a gate plate 5, an installation groove 503 is opened on the inner side of the fishway guard plate 101, a guide frame 502 is fixed on the groove wall of the installation groove 503, the gate plate 5 is slidably connected between the guide frames 502, the bottom of the installation groove 503 is connected to a lifting screw 501 through a bearing, and the two ends of the gate plate 5 are threadedly sleeved on the corresponding lifting screw 501, the top of the fishway guard plate 101 is fixedly connected with a bracket 504, and the top of the bracket 504 is fixedly installed with a lifting motor 505, and the output end of the lifting motor 505 is fixedly connected to the upper end of the lifting screw 501.

[0032] By adopting the above scheme, the stability of the installation of the gate plate 5 is improved. Starting the lifting motor 505 can drive the two lifting screws 501 to rotate synchronously, and then it is convenient to drive the gate plate 5 to move upward and downward, so as to open the gate wider and narrower, and to accurately adjust the water flow speed in the fishway; for some fish that adapt to slow water flow, by moving the gate plate 5 downward to appropriately close the gate, the water flow speed in the fishway can be reduced, allowing these fish to migrate smoothly in a relatively slow water flow environment. For some fish that adapt to strong water flow, by moving the gate plate 5 upward, the gate can be appropriately opened to increase the water flow speed, so as to meet the fish's requirements for the water flow environment.

[0033] Specifically, the guide mechanism also includes a guide plate 4, which is fixedly connected to the side wall of the adjusting rod 401, and the top of the adjusting rod 401 is sleeved and fixed with a worm gear 402 and a gear 407.

A stepper motor 405 is fixedly installed on the support plate 406, and the output end of the stepper motor 405 is fixedly connected to the transverse rod 403. The transverse rod 403 is fixedly connected with evenly distributed worms 404, and the worms 404 are meshed with the corresponding worm wheels 402.

[0034] By adopting the above scheme, the stability of the installation structure of the guide plate 4 is improved. The stepper motor 405 is started to drive the traverse rod 403 to rotate, and then the worm gear 402 is driven to rotate through the worm 404, and then the adjustment rod 401 and the guide plate 4 are driven to rotate, so as to realize the flexible adjustment of the rotation angle of the guide plate 4. By adjusting the angle between the guide plate 4 and the fishway guard plate 101, it is convenient to realize different degrees of energy dissipation and meet different flow velocity and flow state requirements. The close cooperation between the gate mechanism and the guide mechanism is conducive to the coordinated optimization of the water flow velocity distribution. When the gate plate 5 is opened widely and the water flow velocity becomes faster overall, the guide plate 4 can guide part of the water flow to the edge or corner of the fishway body 103, thereby reducing the water flow velocity in the central area and forming a combination of fast and slow water flow velocity distribution to meet the different needs of different fish for water flow velocity in different positions.

[0035] Specifically, a clearance groove 9 is provided on the fishway guard plate 101 , and the meshing ends of the worm wheel 402 and the worm 404 extend into the clearance groove 9 .

[0036] The above solution makes it easy for the worm 404 to drive the worm wheel 402 to rotate, and is easy to use.

[0037] Specifically, a tunnel roof 2 is fixedly installed on the top of the tunnel portion 104, a uniform white light source LED lamp 201 is fixedly installed on the bottom of the tunnel roof 2, and two support rods 202 are also connected to the bottom of the tunnel roof 2 through bearings, and a semi-toothed turntable 203 and a gear ring 204 are respectively fixed on the two support rods 202, the semi-toothed turntable 203 and the gear ring 204 are meshingly connected, and the gear ring 204 and the gear 407 are meshingly connected.

[0038] By adopting the above scheme and utilizing the phototaxis characteristics of fish, the white light source LED lamp 201 is conducive to attracting and inducing fish to enter the bionic ecological fishway, and is convenient for stably installing the semi-toothed turntable 203 and the gear ring 204. Through the transmission principle of the gear ring 204 and the gear 407, when the gear 407 rotates, it is convenient to drive the gear ring 204 and the semi-toothed turntable 203 to rotate, and it is convenient to drive the feeding box 3 on the semi-toothed turntable 203 to adjust a certain angle, which is conducive to expanding the feeding range of fish food, facilitating the attraction of fish schools in a larger range, increasing the probability of fish schools entering the fishway, and helping fish schools to pass through the fishway smoothly.

[0039] Specifically, the feeding box 3 is fixedly mounted on the half-tooth turntable 203 , a feeding tube 301 is fixedly connected to the front bottom of the feeding box 3 , and a solenoid valve 302 is fixedly mounted on the feeding tube 301 .

[0040] By adopting the above solution, it is convenient to install the feeding box 3, and it is convenient to put fish food into the fishway body 103 through the feeding tube 301. The opening and closing of the feeding tube 301 can be controlled by the electromagnetic valve 302, which is convenient to use.

[0041] Specifically, the pulse fish-blocking electric fence includes a pulse current generator 601 and a stainless steel electrode tube 7, the pulse current generator 601 and the stainless steel electrode tube 7 are electrically connected through a wire, two cement piles 6 are fixedly installed on the dam body 1, and connecting rings 604 are fixedly connected to the inner walls of the cement piles 6, and fixing rings 603 are sleeved on the connecting rings 604, and steel strands 602 are fixedly installed between the fixing rings 603, and the stainless steel electrode tubes 7 are provided in plurality and are evenly distributed on the steel strands 602.

[0042] The above scheme is adopted to facilitate the stable installation of the pulse fish-blocking electric fence. The pulse fish-blocking electric fence uses electrodes as carriers of direct current, and stimulates the fish's neuromuscular system by generating an invisible power grid in the water to achieve the effect of blocking and driving fish. When the pulse current generator 601 generates a pulse current under the drive of the power supply, the current is transmitted to the stainless steel electrode tubes 7 through the connecting wires. The stainless steel electrode tubes 7 are arranged at intervals in the water. Since water is a conductor, when current passes between the stainless steel electrode tubes 7, a pulse electric field is formed in the water, which achieves the effect of blocking and driving fish, and ensures that the fish enter the fishway according to the predetermined path.

[0043] Specifically, an upper hanging ring 704 is fixedly installed on the steel strand 602 , the bottom of the upper hanging ring 704 is fixedly connected to a lower hanging ring 702 via an insulating block 703 , a hinged ring 701 is slidably sleeved in the lower hanging ring 702 , and the stainless steel electrode tube 7 is fixedly connected to the bottom of the hinged ring 701 .

[0044] The above scheme facilitates the stable installation of the stainless steel electrode tube 7, and facilitates the free tilting of the stainless steel electrode tube 7 under the impact of the water flow, so that large floating objects in the water can slide smoothly through the stainless steel electrode tube 7. The stainless steel electrode tube 7 can also automatically reset, which is easy to use and helps to avoid accidents caused by blockage or shielding of the pulse fish intercepting electric fence that affect the efficiency of use.

[0045] Specifically, a controller 8 is fixedly installed in the middle of the bracket 504 , and a water flow sensor 105 is fixedly installed at the bottom of the fishway body 103 .

The water flow sensor 105 detects the change of water flow and transmits a signal to the controller 8. The controller 8 controls the operation of the lifting motor 505 and the stepper motor 405, and then facilitates the adjustment of the opening and closing degree of the gate 5 and the rotation angle of the guide plate 4 to adapt to the change of water flow, adjust the appropriate water flow in the fishway, and provide convenience for the fish school.

[0047] Working principle of the present invention: When in use, the controller 8 starts the pulse current generator 601, and the current is transmitted to the stainless steel electrode tube 7 through the connecting wire. The stainless steel electrode tube 7 is arranged at intervals in the water. When current passes between the stainless steel electrode tubes 7, a pulse electric field is formed in the water, which achieves the function of blocking and driving fish, and ensures that the fish enter the fishway according to the predetermined path. After the large floating objects in the water slide smoothly through the stainless steel electrode tube 7, the stainless steel electrode tube 7 automatically swings and resets. It is easy to use and helps to avoid the accidental occurrence of blockage and shielding of the pulse fish-blocking electric fence that affects the efficiency of use.

[0048] The controller 8 starts the stepper motor 405, and the slewing rod 403 drives the worm 404, the worm wheel 402, the adjusting rod 401, and the guide plate 4 to rotate. The adjusting rod 401 drives the gear 407, the gear ring 204 and the half-tooth turntable 203 to rotate, and then drives the feeding box 3 on the half-tooth turntable 203 to adjust a certain angle, and opens the solenoid valve 302 to allow the feeding tube 301 to put fish food into the fishway, which is beneficial to expanding the feeding range of fish food and facilitating the attraction and induction of fish schools in a larger range. The white light source LED lamp 201 is also beneficial to attracting and inducing fish to enter the bionic ecological fishway.

[0049] The water flow sensor 105 detects the change of water flow and transmits the signal to the controller 8. The controller 8 starts the lifting motor 505. The gate mechanism and the guide mechanism cooperate to optimize the water flow velocity distribution, adjust the opening and closing degree of the gate plate 5, and the angle between the guide plate 4 and the fishway guard plate 101 to adapt to the change of water flow, adjust the appropriate water flow in the fishway, provide convenience for the fish school, and meet the migration needs of different fish.
