[0002] Fish resource survey is the core of aquatic ecological survey. Usually, fish resource survey mainly adopts manual field survey method, which is to manually set fishing nets or place ground cages and other facilities to catch the fish on the shore, and then manually count the types and quantities of fish resources. The manual field survey method is costly, inefficient, time-consuming and labor-intensive, and the fishing net has poor capture effect, making it difficult to achieve fully automatic fishing, counting and releasing processes.
[0003] Although, some automatic fish resource survey equipment has appeared now, see patent application number 202210892830.4, its automatic sinking and floating mechanism adopts a vertical drive push rod, and through the telescopic action of the vertical drive push rod, the fishing main box is driven to move up and down. When the flow rate of the water area exceeds a certain value, the flowing water will push the fishing main box, making the service life of the vertical drive push rod shorter. And because the vertical drive push rod is fixedly installed at the other end of the horizontal fixed rod, once the vertical drive push rod is fixedly installed, the horizontal position of the fishing main box cannot be adjusted.

[0005] Moreover, the existing intelligent fish resource survey equipment does not have any protection measures for the fish collecting cages. When the water flow velocity or wind speed exceeds the set threshold, the equipment may be damaged due to excessive water flow velocity or wind speed. Utility Model Content

[0069] Embodiment 2
[0070] The embodiment of the utility model provides a fish resource survey system, comprising an electric control box 9 and the fish resource survey equipment as described in the first embodiment, wherein the lifting mechanism, fish outlet opening and closing mechanism, camera 7, and fish attracting light 6 of the fish resource survey equipment are electrically connected to the electric control box 9 respectively.
[0071] Furthermore, the fish resource survey system of the present invention further comprises a flow meter for detecting the flow velocity of water in the water area, and the flow meter is electrically connected to the electric control box 9. The electric control box 9 is arranged on a bracket.
[0072] Furthermore, the fish resource survey system of the present invention also includes a wind speed sensor for detecting wind speed, and the wind speed sensor is electrically connected to the electric control box 9 .
[0073] When the water flow velocity in the water area exceeds the first set threshold, the fish collecting cage 5 is lifted by the lifting device. When the wind speed exceeds the second set threshold, the fish collecting cage 5 is placed in the water area. When the water flow velocity in the water area exceeds the first set threshold and the wind speed exceeds the second set threshold, the fish collecting cage 5 is horizontally moved to a place close to the column 1 by the translation device, so as to avoid the fish collecting cage 5 being damaged due to excessive water flow velocity or excessive wind speed.
[0074] Furthermore, the fish resource survey system of the present invention also includes a control host, and the electric control box 9 is communicatively connected with the control host.

[0080] The workflow of aquatic resource survey of the utility model: the fish resource survey is installed in the water area with relatively rich aquatic resources. When working, the water flow velocity in the water area is detected in advance by the flow meter. The next step of work can be carried out when it does not exceed the set flow velocity (limit 2.0m / s). The fish collecting cage 5 is lowered to the target water area, and the fish attracting light 6 is turned on to attract the fish to the vicinity of the fish collecting cage 5, and enter the inside of the fish collecting cage 5 through the conical fish collecting mouth. The conical fish collecting mouth plays the role of preventing escape. After the set time is reached, the lifting mechanism is automatically turned on to lift the fish collecting cage 5 to the set position, and the camera 7 is extended into the inside of the fish collecting cage 5. The camera 7 is turned on to take pictures of the fish resources inside the fish collecting cage 5. The pictures are transmitted to the background by the remote data transmission module for intelligent fish identification, and then the data processing and analysis platform performs data processing and analysis to form a survey report. The platform automatically issues a release signal remotely, controls the opening of the fish outlet below the fish collecting cage 5, releases the fish, and automatically closes the fish outlet after a certain time delay. The fish collecting cage 5 enters the working position again to carry out the next workflow. When the current meter detects that the water velocity in the water area exceeds the set velocity (limit 2.0 m / s), the risk avoidance program is automatically started, and the lifting mechanism is started to lift the fish collecting cage 5 to a safe height.
[0081] When the electric hoist 3 receives the instruction from the electric control box 9, the electric hoist 3 starts to work, and the motor of the electric hoist 3 drives the lifting rope to move up and down, thereby driving the lifting and lowering of the entire survey equipment. When the motor of the electric hoist 3 drives the wire rope to move up and down, the guide rail provides the correct route for the rope to ensure stability during the lifting process. When the fish collecting box descends to the target water area every day, the flow rate of the water flow in the water area is first detected by the current meter. If it does not exceed the set flow rate, the fish collecting cage 5 can be placed in the predetermined water area. After taking pictures of the collection results in the fish collecting cage 5, the fish collecting cage 5 descends. When it is at a certain distance from the water surface, the release mechanism is then started to automatically release the fish in the fish collecting cage 5 back to the water area. When the fish collecting cage 5 and the fish attracting light 6 are working, the wire rope is used to fix and support the fish collecting cage 5 and the fish attracting light 6 to maintain the stability of the fish collecting cage 5 and the fish attracting light 6. When the fish collecting cage 5 descends to the target water area, the fish attracting light 6 can be turned on to attract the fish to the vicinity of the fish collecting cage 5. When the fish collecting cage 5 is lifted to the set position, the camera 7 takes pictures of the fish resources collected inside the fish collecting cage 5, and transmits the pictures to the background through the remote data transmission module for intelligent fish identification, and then the background software performs data processing and analysis.
[0082] The bird-repelling device 8 can be a wind-powered bird-repelling device 8. When wind blows toward the wind-powered bird-repelling device 8, the blades will start to rotate, and the reflectors on the blades will reflect sunlight to achieve the effect of repelling birds.
[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
