[0002] A fishway is an artificial water channel for fish to migrate through sluices or dams. It is a remedial measure taken to protect the habits of fish by building artificial water channels on sluices or dams for human activities. Fishway monitoring equipment uses technical means such as cameras to record and distinguish the number and types of fish passing through the fishway, and analyze the number and types of fish.

[0003] According to the patent publication number CN213182818U, a fishway fish monitoring device relates to the field of fishway technology, which includes a fishway pipe with two ends open, the inlet and outlet ends of the fishway pipe are respectively provided with a circle of first infrared grating and second infrared grating, the top plate and side plate of the fishway pipe are respectively installed with a first image acquisition box and a second image acquisition box, and the first image acquisition box and the second image acquisition box are both provided with underwater cameras and underwater light sources. The problem of inaccurate fishway monitoring data when the water source is turbid and the swimming fish overlap in the prior art is solved.

[0004] The above description introduces the fishway detection device. The existing fishway detection device has the following problems:

[0005] 1. Existing fishway detection devices usually use visual methods to collect information about the types and numbers of fish passing through the fishway. The fish inside the fishway are easily affected by factors such as water flow, which causes some fish to swim through at a faster speed. It is impossible to effectively collect information about the types and numbers of fish passing through, which greatly reduces the accuracy of the device's detection.

[0006] 2. The existing fishway detection device usually has a fixed size of the fishway entrance and exit, and cannot be flexibly adjusted according to different situations during use. At the same time, the existing fishway detection device has a poor buffering effect, and is prone to impact the fishway when the water flow is large, causing fish to pass quickly and even damaging the internal components of the fishway. Utility Model Content

[0007] The purpose of the utility model is to solve the technical problems in the prior art that the information such as the types and quantity of passing fish cannot be effectively collected, which greatly reduces the accuracy of device detection and the buffering effect of the fishway is not good, and to propose an electrode type fishway information collection and detection device.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electrode-type fishway information collection and detection device, comprising a box body, a slow-flow shell is fixed inside the box body, a rotating plate is provided inside the slow-flow shell, and there are two groups of rotating plates, and the rotating plates are respectively located at positions close to the entrance and exit ends of the slow-flow shell, one side of the rotating plate is penetrated by a guide hole, one side of the rotating plate is attached with a turntable, one side of the turntable is connected to a metal electrode sheet, and a buffer plate is provided at the entrance and exit ends of the slow-flow shell.

[0009] It can be seen that in the above technical solution, the shell part of the fishway is composed of a box body and a slow-flow outer shell. When entering the fishway, the water flow and the fish need to pass through the buffer plate, the rotating plate to the collection section inside the slow-flow outer shell in sequence, and finally be discharged. Metal electrodes are added to stimulate the fish in the collection section to make them swim repeatedly, which improves the collection effect and facilitates personnel to inspect the accuracy of the device's judgment results.

[0010] Preferably, a collection shell is bolted to the top and side of the box body respectively, and one end of the collection shell is connected to a collection component.

[0011] It can be seen that in the above technical solution, the acquisition component is installed using a acquisition shell so that the camera in the acquisition component is located in an independent space.

[0012] Preferably, a rotating rod is fixed between the two rotating disks, and the rotating disk is axially connected to the rotating plate at the center position, and a driving motor is provided in the space between the slow flow shell and the top of the box body.

[0013] It can be seen that in the above technical solution, the turntables at both ends are connected by a rotating rod, and the rotating rod can be driven to rotate the turntable together with the metal electrode sheet.

[0014] Preferably, the rotating end of the driving motor and the surface of the rotating rod are both connected with sprockets, a chain is provided in the interface at the top of the slow-flow housing, and both ends of the chain are respectively sleeved on the surface of the sprocket.

[0015] It can be seen that in the above technical solution, the drive motor is connected to the rotating rod by a sprocket chain transmission method, so that the drive motor drives the rotating rod to rotate when working.

[0016] Preferably, the bottom end portion of the buffer plate is away from the bottom surface of the slow-flow shell, and the buffer plate is close to two end positions of the box body.

[0017] It can be seen that in the above technical solution, water flow needs to pass through the buffer plate and the two end parts of the slow-flow shell when entering the buffer shell. The shape of the buffer plate and the slow-flow shell can play a role in buffering the water flow.

[0018] Preferably, the rotating plate is movably connected to the slow-flow shell, a rotating motor is provided in the space between the bottom of the slow-flow shell and the bottom of the box body, and the rotating end of the rotating motor is connected to the connection at the bottom of the rotating plate.

[0019] It can be seen that in the above technical solution, the rotating plate can be rotated by a rotary motor drive so as to facilitate the control of the size of the partial opening of the rotating plate.

[0020] Preferably, a spring array is welded on one side of the rotating plate, a baffle is provided at one end of the spring, and one side of the baffle is in contact with the inner wall of the slow-flow shell.

[0021] It can be seen that in the above technical solution, the baffle is connected to the spring on the rotating plate, and the rebound force of the spring can be used to make the baffle movable, thereby ensuring that the rotating plate can rotate and playing a sealing role.

[0022] Beneficial Effects

[0023] 1. In the utility model, metal electrode sheets are added so that the fish inside the box can swim repeatedly in the channel of the slow-flow shell, which increases the collection time of the visual collection component and greatly improves the accuracy of the device's detection. At the same time, the entrance and exit of the fishway are closed, and the accuracy of the device's detection can be tested during the electrode stimulation of the fish inside, without the need for personnel to move to the site for inspection.

[0024] 2. In the utility model, the metal electrode sheet is rotated to change its position, so that the metal electrode sheet can contact the water at the bottom of the fishway when in use, ensuring that the fish in the fishway can be stimulated to swim repeatedly by electrodes normally. At the same time, when rotating to the bottom of the fishway, the guide holes in the fishway can be fitted and closed to prevent stimulation of fish outside the fishway, thus realizing automation, simple structure and low cost, and making full use of the space inside the fishway.

[0025] 3. In the utility model, the buffer shell and the internal buffer plate and rotating plate can effectively buffer the water flow. The buffer shell has large openings at both ends and a narrow middle section, so that the water flow will slow down when entering and leaving the fishway, thereby forming a buffer effect, which can guide fish to pass through the fishway smoothly and help reduce the impact force of the water flow. At the same time, the buffer plate can prevent the water flow from directly impacting the inside of the fishway and avoid the problem of damage to the components inside the fishway due to the impact of the water flow. Finally, the guide holes of the rotating plate can play a buffering role again.

[0026] 4. In the utility model, the size of the opening of the inlet and outlet of the buffer shell can be controlled by rotating the rotating plate, so that the size of the opening can be adjusted according to different situations, which improves the flexibility of the device, has a simple structure and is easy to operate.

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0036] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment:

[0038] Embodiment 1:

[0039] Reference Figure 1-6An electrode-type fishway information collection and detection device comprises a box body 1, a slow-flow shell 2 is fixed inside the box body 1, the box body 1 and the slow-flow shell 2 constitute the shell part of the fishway, after the fishway is installed at a specified position, the fish enters the slow-flow shell 2 through the entrance end of the box body 1, the top and side of the box body 1 are bolted with a collection shell 15, one end of the collection shell 15 is connected to a collection component 16, two sets of collection components 16 in different orientations are used to visually collect the passing fish, the collection component 16 is composed of a shell and a camera and other components, and is installed at one end of the collection shell 15 on the surface of the box body 1, the collection shell 15 and the collection component 16 are respectively located above and on one side of the box body 1, and the number can be increased according to demand As well as the installation position, the advantage of the collection component 16 being located in different positions is that it can be used to collect fish from different perspectives, avoiding the situation where the fish overlap when swimming and resulting in the failure to collect information, thereby improving the collection effect. The type, quantity, swimming speed and other results of the fish can be obtained through the collected information and combined with the system algorithm. It is necessary to explain that the part facing the collection end of the collection component 16 is made of glass, which is equivalent to the top and side of the box body 1 and the top and side of the slow flow shell 2 are all glass, which can help the camera to collect information, and the cover plate is installed at the opening on the surface of the collection shell 15 through a hinge, which can be manually opened later to clean the inside or maintain the internal components.

[0040] A rotating plate 4 is provided inside the slow-flow shell 2, and there are two groups of rotating plates 4, and the rotating plates 4 are respectively located near the entrance and exit ends of the slow-flow shell 2. A guide hole 8 is penetrated on one side of the rotating plate 4, and a turntable 5 is attached to one side of the rotating plate 4. A metal electrode sheet 6 is connected to one side of the turntable 5. Guide holes 8 are opened on the rotating plates 4 at the head and tail ends of the buffer shell, and the fish eventually enter or swim out of the slow-flow shell 2 through the guide holes 8. The metal electrode sheet 6 on the turntable 5 can be used to perform electrode stimulation on the fish inside the slow-flow shell 2, so that the fish can swim repeatedly in the collection section, thereby improving the effect of information collection. At the same time, the accuracy of the device detection can be tested during the electrode stimulation of the fish inside. Further, after the system detects the type of fish in the fishway, due to errors in the detection results, the personnel can obtain the type of fish through multiple groups of photos collected by the collection component 16, and compare them with the detection results. Repeatedly do this to determine the accuracy of the detection result. It is approximately what percentage, and there is no need for personnel to move to the site for inspection.

[0041] It is further explained that the metal electrode sheets 6 are installed at the head and tail ends of the fishway, and are used to receive power supply and transmit data, and cooperate with components such as power connectors, data connectors and voltage controllers to enable it to work normally. The slow-flow shell 2 and rotating plate 4 and other components are all made of insulating materials, and the guide holes 8 are closed when the electrode is operated to prevent the current from being conducted into the water outside the slow-flow shell 2. The voltage and current of the electrode are reasonably designed to ensure that the voltage and current of the electrode will not have adverse effects on the fish. The output of the electrode can be controlled by using devices such as voltage and current limiters.

[0042] Embodiment 2:

[0043] Reference Figure 1-6 The metal electrode sheet 6 is installed on the turntable 5 and can rotate with the turntable 5. The turntable 5 is in contact with one side of the rotating plate 4. Under normal circumstances, the turntable 5 and the metal electrode sheet 6 are located near the top of the slow-flow shell 2, and the guide hole 8 is also normally open. When electrode operation is required, the turntable 5 is rotated to the position of the guide hole 8, and the guide hole 8 is closed. At this time, the electrode sheet is located near the bottom of the slow-flow shell 2 to ensure that the electrode sheet can contact with water to complete the electrode operation. A rotating rod 7 is fixed between the two turntables 5, and the center position of the turntable 5 and the rotating plate 4 is axially connected. A driving motor 11 is provided in the space between the slow-flow shell 2 and the top of the box body 1. The driving motor 11 The rotating end and the surface of the rotating rod 7 are both connected with a sprocket 9, a chain 10 is provided in the interface on the top of the slow-flow shell 2, and the two ends of the chain 10 are respectively sleeved on the surface of the sprocket 9, and the two turntables 5 are connected together by the turntable 7. Therefore, only one set of driving components is needed to complete the simultaneous rotation of the two turntables 5, and the turntable 7 is rotated by the sprocket 9, chain 10 and driving motor 11 and other components. When the rotating end of the driving motor 11 rotates, the turntable 7 can be rotated by the action of the sprocket 9 and the chain 10, so that the turntable 5 rotates together with the electrode sheet. At the same time, the gear set, connecting rod and other components can be added to change the installation position of the driving motor 11, and the added components can be changed according to the needs.

[0044] Embodiment three:

[0045] Reference Figure 1-6The openings at both ends of the slow-flow shell 2 are larger, and the middle part is narrower. The middle part is the fish swimming collection section. Since the openings at both ends of the fishway are larger, the water flow will slow down when entering and leaving, thereby forming a buffering effect, and at the same time can guide the fish to pass through the slow-flow shell 2 smoothly, which helps to reduce the impact force of the water flow. A buffer plate 3 is provided at the entrance and exit of the slow-flow shell 2. The bottom end part of the buffer plate 3 is away from the bottom surface of the slow-flow shell 2, and the buffer plate 3 is close to the two end positions of the box body 1. The buffer plate 3 is fixed to the open end of the slow-flow shell 2, and there is a gap from the bottom of the buffer plate 3 to the bottom of the slow-flow shell 2. It further explains that the water flow can only enter the collection area in the middle section of the slow-flow shell 2 after entering the box body 1 through this gap and the guide hole 8. The buffer plate 3 cooperates with the slow-flow shell 2 to avoid damage to the components inside the box body 1 caused by water flow impact.

[0046] Embodiment 4:

[0047] Reference Figure 1-6 The rotating plate 4 is movably connected to the slow-flow shell 2. The top and bottom ends of the rotating plate 4 are axially connected to the two sides of the slow-flow shell 2, so that the rotating plate 4 can rotate freely in the slow-flow shell 2. The opening size of the rotating plate 4 can be controlled according to the water flow and other conditions. There is no need to use the guide hole 8 to complete the circulation of water and fish. A rotating motor 12 is provided in the space between the bottom of the slow-flow shell 2 and the bottom of the box body 1, and the rotating end of the rotating motor 12 is connected to the connection at the bottom of the rotating plate 4. The bottom of the rotating plate 4 adopts the rotating motor 12 and other components to enable it to complete its own rotation.

[0048] A spring 13 is welded in an array on one side of the rotating plate 4, and a baffle 14 is provided at one end of the spring 13, and one side of the baffle 14 is in contact with the inner wall of the slow-flow shell 2. It is further explained that the baffle 14 is connected to the inner wall of the slow-flow shell 2 by the spring 13 on both sides of the rotating plate 4. In order to ensure that the rotating plate 4 can rotate normally, under normal circumstances, the baffle 14 is in contact with the inner wall of the slow-flow shell 2 by the rebound force of the spring 13. However, during rotation, the baffle 14 is squeezed by the spring 13 to cause it to displace, thereby allowing the rotating plate 4 to rotate and completing the controllable opening. One end of the baffle 14 has a rounded corner so that it can be smoothly displaced by force.

[0049] In summary:

[0050] 1. The slow-flow housing 2 and the buffer plate 3 can prevent the impact of the water flow from directly damaging the internal components;

[0051] 2. The metal electrode sheet 6 can be used to make the fish in the collection area swim repeatedly to improve the collection effect;

[0052] 3. The rotation of the turntable 5 can change the position of the electrode sheet and control the opening and closing of the guide hole 8;

[0053] 4. The rotating plate 4 part can be rotated so that the size of the opening of this part can be controlled, and the flexibility is high.
