[0001] The utility model relates to the technical field of fishway engineering, in particular to an online monitoring channel for fishways with high flexibility. Background Art

[0002] A fishway is a channel for fish migration. It is a remedial measure taken when human activities destroy the fish migration channel. Generally, artificial water troughs are built on sluices or dams to protect the habits of fish.

[0003] The fishway detection device is a device used to monitor and evaluate the performance of fishways. Fishways are passages set up to help fish overcome obstacles such as dams and hydropower stations. The main purpose of the fishway detection device is to ensure that the fishway can effectively allow fish to pass through and to evaluate its operating effect.

[0004] The publication number is: CN116907892A. The present invention relates to the field of fishway engineering technology, and in particular to a fishway monitoring device. The fishway monitoring device includes a net box, a water collecting tank and a lifting mechanism. A plurality of mesh plates are arranged in parallel and spaced apart inside the net box. The plurality of mesh plates divide the net box into a plurality of accommodating areas along the length direction. A through hole is provided on the end face of one end of the net box along the length direction. A through hole is also provided on the plate surface of each mesh plate, and the opening size of the plurality of through holes decreases successively from one end of the net box opening to the other end opposite thereto. The bottom surface of the net box is fitted and connected with the inner bottom wall of the water collecting tank, and the side portion of the net box close to the bottom surface is fitted and connected with the inner side wall of the water collecting tank. The lifting mechanism is arranged directly above the net box, and the lifting end of the lifting mechanism is connected with the top of the net box. The fishway monitoring device has high monitoring efficiency, a safe working environment, and a display function.

[0005] The above description introduces the fishway and a highly flexible online monitoring channel for the fishway. However, the existing fishway has the following technical problems:

[0006] After the installation of the existing fishway, the staff needs to use the camera housings on the top and sides of the fishway to observe the fish in the fishway and judge the upstream water quality. However, during the observation of the fish, since the camera housing is fixed, the fish cannot be accurately observed, resulting in observation errors. In addition, during the observation process, due to the large amount of impurities and grass plants in the water, the transparent glass at the collection point of the camera housing is easily attached with impurities and grass plants, resulting in blurring of the transparent glass. The camera housing cannot accurately shoot the fish, and thus cannot judge the quality of the upstream water. Utility Model Content

[0007] The utility model aims to solve the technical problems that the prior art cannot adjust the focal length of the camera housing and cannot remove weeds and impurities attached to the transparent glass surface, and proposes a highly flexible fishway online monitoring channel.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a highly flexible fishway online monitoring channel, comprising a fishway, a shell is provided on the top and side surfaces of the fishway, a support is provided inside the shell, a slide is provided inside the support, a screw is installed inside the slide, a moving part is provided on the surface of the screw, a magnetic suction module is connected to the top surface of the moving part, a camera housing is connected to the top surface of the magnetic suction module, transparent glass is provided on the top and side surfaces of the fishway, a washer is provided on the surface of the transparent glass, a water spray hole is provided on one side of the washer, a magnetic suction cup is provided on the other side of the transparent glass, a hose is provided on the top surface of the washer, and a water tank is provided on the top surface of the fishway.

[0009] It can be seen that in the above technical solution, after the staff puts the fishway into the water, the fish will enter through the entrance of the fishway. When the fish enters the fishway, the output end of the motor inside the shell rotates, driving the screw to rotate, so that the moving part sleeved on the surface of the screw moves back and forth, and a magnetic module is installed on the top surface of the moving part, and the top of the magnetic module is adsorbed with a camera housing. When the screw rotates, the moving part will drive the magnetic module and the camera housing to move back and forth, thereby adjusting the focal length of the camera housing to take more accurate pictures of the fish in the fishway. When a component at the screw is damaged and the camera housing cannot move, the camera housing will not be able to accurately photograph the fish. At this time, the staff will open the shell, remove the camera housing from the top surface of the magnetic module, and place the camera housing at a suitable position on the top surface of the support, so as to photograph the fish. Transparent glass is installed on one side to protect the camera housing and prevent water from entering the camera housing and causing damage. Since the fishway is usually placed in water, long-term water flow will cause weeds and impurities in the water to adhere to the surface of the transparent glass, affecting the camera housing's shooting of the fish school. When a large amount of weeds or impurities are attached to the surface of the transparent glass, the telescopic end of the electric push rod will drive the magnetic suction cup to move up and down. Since the magnetic suction cup and the cleaner are magnetically connected, the magnetic suction cup will drive the cleaner to move up and down when it moves up and down. There are two groups of cleaners, which can clean the entire piece of glass. When the cleaner moves up and down, the hose on the top surface of the cleaner will transport the cleaning agent in the water tank located on the top surface of the fishway to the inside of the cleaner, and then the water spray hole on one side of the cleaner will spray the cleaning agent inside the cleaner on the surface of the transparent glass, thereby cleaning the transparent glass in all directions, making the camera housing shoot clearer.

[0010] Preferably, the support member is located inside the shell, and one end of the support member is fixedly connected to the inside of the shell.

[0011] It can be seen that in the above technical solution, the support member is located inside the shell so that the camera housing can be better moved left and right, so that the camera housing can take clearer pictures.

[0012] Preferably, the screw rod is connected to the support member, and the moving member can be slidably connected on the surface of the screw rod.

[0013] It can be seen that in the above technical solution, when the screw rod rotates, the moving part can slide on the surface of the screw rod, and the moving part can slide in the slide groove to prevent the moving part from derailing.

[0014] Preferably, the magnetic attraction module is fixed to the bottom end of the camera housing, and the magnetic attraction module is magnetically attracted to one side of the moving part and the supporting part respectively.

[0015] It can be seen that in the above technical solution, when the screw fails, the staff can remove the camera housing at any time and put it in a suitable position for shooting the school of fish, and it is also convenient for the staff to carry out maintenance.

[0016] Preferably, there are two groups of cleaning devices, and the cleaning devices are respectively located on one side of the transparent glass, and the water spray holes are arrayed on one side of the cleaning devices.

[0017] It can be seen that in the above technical solution, since the magnetic suction cup and the cleaning device are magnetically connected, when the magnetic suction cup moves, the cleaning device will be driven to move together, and the water spray hole can spray water on the surface of the transparent glass, so that the transparent glass can be cleaned more clearly and brightly.

[0018] Preferably, the water tank is rectangular, the two ends of the hose are respectively connected to the top surface of the cleaning device and the top surface of the water tank, an electric push rod is provided at the top of the magnetic suction cup, and the telescopic end of the electric push rod is fixedly connected to the surface of the magnetic suction cup.

[0019] It can be seen that in the above technical solution, when the telescopic end of the electric push rod works, it will drive the magnetic suction cup to move together, so that the cleaner can clean the surface of the transparent glass, and during the movement, the hose will transport the cleaning agent from the water tank to the cleaner, so that the water spray hole will spray the cleaning agent on the surface of the transparent glass, thereby cleaning the glass surface in all directions.

[0020] Preferably, the magnetic chuck and the cleaning device are flush with each other, and two sides of the transparent glass are tightly fitted with one side of the magnetic chuck and the cleaning device respectively.

[0021] It can be seen that in the above technical solution, when the magnetic suction cup moves up and down, it will drive the cleaning device to move up and down.

[0022] Preferably, there are two groups of camera housings, and the camera housings are located in corresponding shells, and the two groups of camera housings are respectively located at the center of the corresponding transparent glass, and the support member is Z-shaped.

[0023] It can be seen that in the above technical solution, the camera housing is located at the center of the transparent glass, which can better observe the fish in the fishway and facilitate information collection.

[0024] Beneficial Effects

[0025] In the utility model, image information of fish schools in the fishway is collected by moving two groups of cameras. The movement of the camera can effectively adjust the focal length of the camera. The camera can adjust the focal length automatically according to the size of the fish in the fishway, so as to collect information of the fish schools in the fishway more accurately. The camera is moved by an automated structure so that the camera can automatically adjust the focal length according to the size of the fish when the fish passes through the fishway, thereby realizing the automation of focal length adjustment and improving the flexibility of the fishway.

[0026] In the utility model, by adopting a Z-shaped support member, the camera housing located on the top surface of the support member can always be located at the center of the transparent glass, so that the fish in the fishway can be accurately photographed, and by adopting a magnetic suction module to install the camera housing, the camera housing can be quickly disassembled and installed, and when the screw rod and other components fail, the staff can manually remove the camera housing from the moving part and place it on the top surface of the support member for magnetic suction to complete the quick installation, and the position of the camera can be manually adjusted, and it is convenient for maintenance personnel to repair the screw rod and other components at a later time, and the effective space inside the shell is fully utilized.

[0027] In the utility model, two sets of cleaners are used to clean the transparent glass, so that weeds and impurities attached to the surface of the transparent glass can be easily cleaned. Since a large amount of weeds and impurities will flow into the fishway after installation, a large amount of weeds and impurities will be attached to the surface of the transparent glass after a long period of water washing, thereby affecting the camera's shooting of the fish in the fishway. At this time, the cleaner can remove the weeds and impurities on the glass surface by moving up and down, so that the camera can shoot the fish in the fishway more clearly.

[0028] In the utility model, the weeds and impurities attached to the surface of the transparent glass can be better removed in an all-round manner by adopting a moving cleaning device, so that the camera shooting inside the shell is not affected. The cleaning device is magnetically connected to the magnetic suction cup on the other side of the transparent glass. When the magnetic suction cup moves up and down, the cleaning device is driven to move up and down, thereby cleaning the weeds and impurities on the surface of the transparent glass to ensure the shooting of the camera. The water tank is located above the fishway, and the hose is connected from the top of the water tank. It is connected to the top surface of the cleaning device through the hose hole at the connection between the fishway and the shell, which can prevent the water pipe from being connected from other places, causing water to enter the equipment and causing damage to the equipment.
