Description

Technical Field

[0001] The utility model relates to the technical field of fishway detection, in particular to a fishway detection device based on intelligent fish catching. 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: CN217556857U. The fishway detection device includes a frame assembly, a lighting unit, a scanning unit, a monitoring unit and a control assembly. The frame assembly is provided with a penetrating fishway. The lighting unit, the scanning unit and the monitoring unit are all fixedly arranged on the side wall of the fishway and cooperate with the fishway. The lighting unit, the scanning unit and the monitoring unit are all electrically connected to the control assembly. The frame assembly includes a frame, an upper sealing plate, a lower sealing plate and a guide component. The upper and lower sides of the frame are respectively sealed with an upper sealing plate and a lower sealing plate. The left and right sides of the frame are symmetrical and sealed with a guide component. The upper and lower ends of the guide component are respectively sealed and connected with the upper sealing plate and the lower sealing plate. The upper sealing plate, the lower sealing plate and the two guide components form a fishway together. This device integrates various functions into one, which is convenient for transportation, installation and maintenance, and convenient for observing fish.

[0005] The above describes the fishway and the fishway detection device. However, the existing fishway detection device for catching fish has the following technical problems:

[0006] The existing fishway detection device can judge the species of fish passing through the fishway by collecting images through a camera. When it is necessary to verify the fish detected at the fishway, it is necessary to manually catch the fish at the fishway exit and manually judge whether the species of the fish is consistent with that judged by the system. This fishing method is relatively low and has certain safety hazards. At the same time, it is impossible to accurately and quickly capture the required fish. Utility Model Content

[0007] The purpose of the utility model is to solve the technical problems that the existing technology requires manual catching of fish to verify the type of fish, and this fishing method is relatively low, there are certain safety hazards, and it is impossible to accurately and quickly catch the required fish. A fishway detection device based on intelligent fish catching is proposed.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a fishway detection device based on intelligent fish catching, comprising a fishway, the side and top surfaces of the fishway are respectively provided with installation boxes, a camera is bolted inside the installation box, an entrance and an exit are provided at both ends of the fishway, a U-shaped plate is respectively provided at one end of the outlet, a moving mechanism is provided on the top surface of the U-shaped plate, the moving mechanism comprises a moving plate, a fishing net is installed on the top surface of the moving plate, and the fishing net is flush with the top surface of the moving plate, a clamping mechanism is provided on the top surface of the moving plate, the clamping mechanism comprises a fixed splint, and the bottom surface of the fixed splint is fixedly connected to the surface of the moving plate.

[0009] It can be seen that in the above technical solution, when it is necessary to capture a certain fish to judge the accuracy of the detection by the camera, the fishway is first installed in the channel through which the fish passes. When the fish enters the fishway through the entrance, the fishing net can be quickly clamped and fixed by setting a clamping mechanism, thereby effectively preventing the fishing net from falling off when catching the fish. When the fish swims to the shooting point of the camera, the fish is photographed through the camera to identify the species of the fish. When the fish passes through the camera, the moving mechanism is driven to move the moving plate in the moving mechanism, and the moving plate moves while driving the fishing net, and finally the fish reaching the exit is captured by the fishing net.

[0010] Preferably, motors are welded at both ends of the U-shaped plate, an output shaft of the motor is key-connected with a threaded rod, and the interior of the movable plate is threadedly connected to the surface of the threaded rod.

[0011] It can be seen that in the above technical solution, when a fish needs to be caught, the fish passes the position of the camera, and the output shaft of the motor in the moving mechanism drives the threaded rod to rotate, and the threaded rod rotates while driving the moving plate to move, and the moving plate drives the fishing net to move, and then the fish reaching the exit is caught by the fishing net.

[0012] Preferably, the top surface of the movable plate is rotatably connected with a movable clamping plate, and bolts are arranged inside the movable clamping plate.

[0013] It can be seen that in the above technical solution, when the fishing net needs to be fixed, the movable clamp is moved by rotating the bolt, and the fishing net is moved by the movement of the movable clamp until the movable clamp and the fixed clamp clamp the fishing net. The fishing net can be quickly fixed by the mutual cooperation of the movable clamp and the fixed clamp, thereby preventing the fishing net from falling off when catching fish.

[0014] Preferably, a fixed plate is welded to the bottom surface of the movable plate, and a gravity sensor is arranged on the top surface of the fixed plate.

[0015] It can be seen that in the above technical solution, by setting a fixing plate, the gravity sensor can be fixed. By setting the gravity sensor, the gravity display value transmitted by the gravity sensor is used to judge whether the fishing net has caught the required fish. The gravity sensor in this article is a piezoresistive gravity sensor. This gravity sensor is made of special materials. When subjected to external force, the resistance value of the material will change, thereby realizing the measurement of gravity, and can accurately and quickly judge whether the fishing net has caught the fish.

[0016] Preferably, a channel is provided inside the fishway, the channel is welded inside the outlet, and infrared counters are provided at both ends of the fishway.

[0017] It can be seen that in the above technical solution, by setting up a channel, the exit of the fishway can be reduced, which can effectively avoid the exit being too large, thereby reducing the probability of catching fish.

[0018] Preferably, the infrared counters are bolted to the inside of the entrance and the passage, and two groups of infrared counters are provided.

[0019] It can be seen that in the above technical solution, by setting an infrared counter, when a school of fish enters the fishway, the number of fish passing through the school of fish can be counted by the infrared counter.

[0020] Preferably, the fishing net is arranged at the exit, and the gravity sensor is located below the fishing net.

[0021] It can be seen that in the above technical solution, the required fish can be easily caught by setting the exit of the fishing net, and the gravity sensor is set under the fishing net, so that it can be judged whether the fishing net has caught fish by the gravity sensor.

[0022] Preferably, a cover plate is provided on the surface of the fishway, and one end of the cover plate is hingedly connected to the surface of the fishway.

[0023] It can be seen that in the above technical solution, by setting a cover, when it is necessary to clean the stains inside the fishway, the stains inside the fishway can be cleaned by opening the cover, and at the same time, the obstruction at the camera can be conveniently wiped, allowing the camera to take clearer pictures.

[0024] Beneficial Effects

[0025] 1. In the utility model, by adopting a moving mechanism, when a fish passes through the camera, a control command is issued by the control end to drive the moving mechanism to move and then move upward through the fishing net to capture the fish reaching the exit. Compared with the existing method, this method can drive the fishing net to move the fish to the top of the fishway through the moving mechanism, so that the later personnel can manually judge the type of fish and determine that the accuracy of the judgment made by the camera is within the specified range. In addition, the capture mechanism and the fishway are integrated for easy use.

[0026] 2. In the utility model, the gravity display value transmitted by the gravity sensor is used to determine whether the fishing net has caught the required fish. When the fish enters the interior of the channel, when the fish passes through the infrared counter, the infrared counter transmits the infrared induction to the system, and the system drives the fishing net to move upward, and then the fish is caught. If the fishing net does not catch the fish, the gravity display value of the fishing net remains unchanged, indicating that the fishing net has not caught the fish. By setting the channel, the exit of the fishway can be effectively reduced, thereby increasing the probability of capture. Compared with the existing method, this method informs the staff through the system that the fishing net has not caught the fish, so there is no need to come to observe. The accuracy of the fish species displayed in the fishway makes the device more intelligent.

[0027] 3. In the utility model, rapid capture can be achieved by adopting a fishing net, and the fish can be effectively prevented from escaping. By adopting a clamping mechanism, the fishing net can be quickly clamped and fixed through the cooperation of a movable clamping plate and a fixed clamping plate. This mechanism can clamp and fix fishing nets of different sizes. When the fishing net needs to be fixed, it is only necessary to pull the fishing net to a suitable length and align the holes on the fishing net with the bolts to clamp and embed them into the holes of the fishing net. This method has two forces to effectively prevent the fishing net from falling off, has a wide range of use, and is simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. 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] Reference Figure 1-5 A fishway detection device based on intelligent fish capture includes a fishway 1, and a mounting box 4 is respectively arranged on the side and top surface of the fishway 1, and a camera 12 is bolted inside the mounting box 4. By arranging the camera 12 on the top and side surfaces of the fishway 1, it is possible to effectively prevent the fish from swimming side by side in the fishway 1, accurately photograph the fish swimming side by side, and judge the species of the passing fish through the system algorithm to sense the swimming direction, speed and position of the fish. According to the analysis result of the system algorithm, the capture device will trigger the automatic moving mechanism 6 to drive the fishing net 7 to move, so that the fishing net 7 can accurately and quickly capture the fish, and judge the species of the passing fish through the system algorithm, so as to make the device intelligent. An entrance 2 and an outlet 3 are arranged at both ends of the fishway 1, and a U-shaped plate 10 is respectively arranged at one end of the outlet 3. A moving mechanism 6 is arranged on the top surface of the U-shaped plate 10, and the moving mechanism 6 includes a moving plate 63, and a fishing net 7 is installed on the surface of the moving plate 63, and a clamping mechanism 5 is arranged on the surface of the moving plate 63.

[0039] The clamping mechanism 5 includes a fixed clamping plate 51, the bottom surface of the fixed clamping plate 51 is fixedly connected to the surface of the moving plate 63, the bottom surface of the moving plate 63 is welded with a fixed plate 8, and the top surface of the fixed plate 8 is provided with a gravity sensor 11. The fishing net 7 is driven by the moving mechanism 6 to move upward, and then the fish that are about to reach the exit 3 are caught. The gravity sensor 11 is located at the bottom of the fishing net 7. By setting the fixed plate 8, the gravity sensor 11 can be fixed. By setting the gravity sensor 11, the gravity display value transmitted by the gravity sensor 11 is used to judge whether the fishing net 7 has caught the required fish. By using the fishing net 7, the required fish can be accurately caught quickly, and the caught fish will sink to the bottom of the fishing net 7, making the fishing net 7 cone-shaped. If the observer comes to the front of the device for a long time, the fish can be placed in the water through the fishing net 7 to prevent other risks of the fish. By using the fishing net 7, other risks of the fish can be prevented and the fish can be caught. Through the cooperation of the camera 12 and the fishing net 7, The camera 12 collects information about the fish, so as to determine the position and swimming speed of the fish to be captured, and cooperates with the lifting of the fishing net 7 to accurately capture the fish at the exit 3. If the gravity value of the gravity sensor 11 at the bottom of the fishing net 7 changes after the fish is captured, it means that the fishing net 7 has captured the fish to be observed. The system informs the staff to come and observe whether the species of the fish is consistent with the species observed in the fishway 1. If no fish is caught, the gravity display value of the fishing net 7 remains unchanged. If the gravity display value does not change, the system informs the staff that the fishing net 7 has not captured the fish to be observed, and there is no need to come and observe. The gravity sensor 11 is used to judge whether the fish is caught in turn, making the device more intelligent. The gravity sensor 11 in this article is a piezoresistive gravity sensor 11. This gravity sensor 11 is made of special materials. When subjected to external force, the resistance value of the material will change, thereby realizing the measurement of gravity, and can accurately and quickly judge whether the fishing net 7 has captured the fish.

[0040] When it is necessary to capture a certain fish to judge the accuracy of the detection of the camera 12, first, when the fish enters the inside of the fishway 1 through the entrance 2, the fishing net 7 can be quickly clamped and fixed by setting the clamping mechanism 5, so as to effectively prevent the fishing net 7 from falling off when catching the fish. By adopting the fishing net 7, the fish can be captured more accurately. When the fish swims to the shooting position of the camera 12, the fish is then photographed by the camera 12 to identify the species of the fish. When the fish passes through the camera 12, the camera 12 detects that the fish is about to reach the exit 3. After the infrared counter 9 in the fish entry channel 13 senses the arrival of the fish, the system sends a control instruction to drive the moving mechanism 6, which moves through the moving plate 63 in the moving mechanism 6. The moving plate 63 moves while driving the fishing net 7 to move. Finally, the fish reaching the exit 3 is captured by the fishing net 7, thereby improving the success rate of fishing.

[0041] Embodiment 2:

[0042] Reference Figure 1-5 Motors 61 are welded at both ends of the U-shaped plate 10, and the output shaft key of the motor 61 is connected with a threaded rod 62. The inside of the movable plate 63 is threadedly connected with the surface of the threaded rod 62. When a fish needs to be caught, when the fish passes the position of the camera 12, a control instruction is sent through the control end to drive the movable mechanism 6, and the output shaft of the motor 61 in the movable mechanism 6 drives the threaded rod 62 to rotate, and the threaded rod 62 rotates while driving the movable plate 63 to move, and the movable plate 63 drives the fishing net 7 to move, and then the fish reaching the exit 3 is caught by the fishing net 7.

[0043] The surface of the movable plate 63 is rotatably connected with a movable clamping plate 52, and the internal thread of the movable clamping plate 52 is connected with a 53 bolt. When the fishing net 7 needs to be fixed, the movable clamping plate 52 is driven to move by rotating the bolt 53, and the fishing net 7 is moved by the movement of the movable clamping plate 52 until the movable clamping plate 52 and the fixed clamping plate 51 clamp and fix the fishing net 7. The fishing net 7 is arranged at the position of the exit 3, and the gravity sensor 11 is located below the fishing net 7. The surface of the fishway 1 is provided with a cover plate 14, and one end of the cover plate 14 is hingedly connected to the surface of the fishway 1. The fishing net 7 can be quickly fixed by the mutual cooperation of the movable clamping plate 52 and the fixed clamping plate 51, thereby preventing the fishing net 7 from falling off when catching fish. When the fishing net 7 needs to be replaced, the movable clamping plate 52 is driven to move by rotating the bolt 53 in the opposite direction until one end of the bolt 53 is separated from the fixed clamping plate 51, and the disassembly of the fishing net 7 can be completed.

[0044] Embodiment three:

[0045] Reference Figure 1-5The fishway 1 is provided with a channel 13 inside, and the channel 13 is welded inside the outlet 3. By providing the channel 13, the outlet 3 of the fishway 1 can be reduced, and the outlet 3 can be effectively prevented from being too large, thereby reducing the probability of catching fish. Infrared counters 9 are provided at both ends of the fishway 1. The principle of the infrared counter 9 in this article is based on the emission, reception and processing of infrared light. Specifically, the transmitter in the infrared counter 9 will continuously emit infrared signals. When these signals encounter objects, they will be reflected or blocked. These reflected or blocked infrared signals are then received by the receiver and converted into electrical signals. And the infrared counter 9 is bolted to the inside of the entrance 2 and the channel 13. By setting the infrared counter 9, when the fish enters the fishway 1, the number of fish passing through the fish can be counted by the infrared counter 9. The counters of the entrance 2 and the exit 3 emit infrared light. When the fish passes through the light, the light will be disconnected, and the number is counted according to the number of disconnections. The infrared counter 9 at the entrance 2 is used to calculate the number of fish, and the infrared counter 9 at the exit 3 is used to sense the position of the fishway to be captured, which is transmitted to the system through the infrared sensing device, and the system issues a control command to drive the moving mechanism 6 to drive the fishing net 7 to capture the fish.

[0046] Working principle: First, the fish enters the interior of the fishway 1. An infrared counter 9 is provided at the bottom of the entrance 2 of the fishway 1 to count the number of fish passing through. Then, when the fish swims to the position of the camera 12, the type of the fish is photographed by the camera 12. If there is no need to observe the type of a certain fish, the system does not need to issue a control instruction to drive the mobile mechanism 6 to capture the fish, and the fish can continue to swim through the exit 3. If it is necessary to observe the accuracy of the fish photographed by the camera 12, when the fish swims to the interior of the channel 13, due to the infrared sensing device provided at the bottom, the position of the fish sensed by the infrared sensing device is transmitted to the system, and the system issues a control instruction to drive the mobile plate 63 to move upward. While the mobile plate 63 moves upward, it drives the fishing net 7 to move upward, and then the fish can be captured.

[0047] In summary:

[0048] 1. The output shaft of the motor 61 drives the threaded rod 62 to rotate, and the threaded rod 62 drives the movable plate 63 to move while rotating, and the movable plate 63 drives the fishing net 7 to move, and then the fish that reach the exit 3 are caught by the fishing net 7.

[0049] 2. The movable clamping plate 52 is driven to move by rotating the bolt 53, and the movement of the movable clamping plate 52 causes the fishing net 7 to move until the movable clamping plate 52 and the fixed clamping plate 51 clamp and fix the fishing net 7. The movable clamping plate 52 and the fixed clamping plate 51 cooperate with each other to quickly fix the fishing net 7, thereby preventing the fishing net 7 from falling off when catching fish.
