The monitoring unit 9 and the camera 9 have the characteristics of sealing and waterproofing and can be submerged below the water surface for use. A hydraulic rod 3 is installed in the box body 1, and the bottom end of the hydraulic rod 3 is connected to the bottom plate 4. A fish-attracting light strip 15 is installed on the inner wall of the bottom end of the box body 1, a snap ring 12 is installed on the inner side of the through hole 11, and an impeller 13 is connected to the snap ring 12. A second water pump 7 is installed on the top of the box body 1, and one end of the second water pump 7 is connected to a guide pipe 8.
[0019] See also Figure 2 、 Figure 3 , the camera 10 protrudes into the box body 1 through the through hole 11, the middle part of the impeller 13 is hollow, the impeller 13 is rotatably engaged with the clamping ring 12, and the water outlet end of the guide pipe 8 is aligned with the blade on one side of the impeller 13. When the fish enters the box body 1, the bottom plate 4 and the box body 1 are closed, and the second water pump 7 is started to cooperate with the guide pipe 8 to flush the impeller 13, thereby causing the impeller 13 to rotate. The rotation of the impeller 13 drives the water in the box body 1 to surge toward the side away from the camera 10, driving the fish to a position away from the camera 10. A first water pump 5 is provided on one side of the second water pump 7, and a booster head 6 is installed at the output end of the first water pump 5. The booster head 6 is provided in the box body 1. After the monitoring is completed, the hydraulic rod 3 pushes out the bottom plate 4 to open the bottom of the box body 1, and then the first water pump 5 is operated. The first water pump 5 cooperates with the booster head 6 to drive the fish in the box body 1 downward, thereby driving the fish out of the box body 1.
[0020] In the present invention, a box body 1 is installed in a breeding pond, an air hole 2 is opened on the box body 1, a monitoring unit 9 is installed on one side of the box body 1, a camera 10 is installed on the side of the monitoring unit 9 facing the box body 1, and the camera 10 passes through a through hole 11 on one side of the box body 1 and protrudes into the box body 1. A clamping ring 12 is installed on the inner side of the through hole 11, and an impeller 13 is rotatably clamped on the clamping ring 12, and the middle part of the impeller 13 is hollow, which is convenient for the camera 10 to monitor;
[0021] During use, the bottom plate 4 is supported by the hydraulic rod 3 to open the bottom side of the box body 1, and then the fish-attracting light strip 15 is turned on. After the fish is lured into the box body 1 by the fish-attracting light strip 15, the camera 10 of the monitoring unit 9 detects the presence of the fish, and the hydraulic rod 3 drives the bottom plate 4 to retract, thereby closing the box body 1. Subsequently, the second water pump 7 is started and cooperates with the guide pipe 8 to flush the impeller 13, thereby rotating the impeller 13. The rotation of the impeller 13 drives the water in the box body 1 to surge toward the side away from the camera 10, driving the fish to a position away from the camera 10, thereby solving the problem that the monitoring effect of the monitoring unit 9 is affected by the fish approaching the camera 10 on the monitoring unit 9.
