9. The fish guiding device based on a biomimetic fishway according to claim 5, characterized in that: The second movable plate (704) is designed to be tilted, and the two second movable plates (704) are designed to be mirror images.

10. A control method for a fish-guiding device based on a biomimetic fishway, employing a fish-guiding device based on a biomimetic fishway as described in any one of claims 1-9, characterized in that: The control method is as follows: S1: First, the operator opens the gate on one side of the bionic fishway body (1) to let the water flow into the bionic fishway body (1) and introduce the migratory fish into it. After the fish enters stably, the gate on this side is closed. Then the gate on the other side of the bionic fishway body (1) is opened. At this time, the sound and light fish attracting component (2) is driven to project lifelike dynamic light spots or light bands to simulate the tail light and shadow generated when the fish swim, or the signal emitted by the group of companions, to guide them to follow the light and shadow, thereby helping the migratory fish to go upstream smoothly. S2: During the long-term use of the sound and light fish attracting component (2), the drive motor (401) causes the worm (402) to rotate. The worm (402) will drive the worm wheel (301) and the push plate (302) to rotate. The push plate (302) will drive the connecting block (304) to slide inside the moving ring (303) and push the moving ring (303) to move back and forth. The moving ring (303) will drive the connecting rod (305) and the cleaning plate (306) to move back and forth. During the movement of the cleaning plate (306), the bristles on the side of the cleaning plate (306) close to the sound and light fish attracting component (2) will come into contact with the sound and light fish attracting component (2). The movement of the cleaning plate (306) will clean the sound and light fish attracting component (2). S3: When the moving ring (303) moves back and forth, it will drive the mounting plate (504) to move. The mounting plate (504) will drive the sealing block (505) to move back and forth inside the fixed cylinder (501). When the sealing block (505) moves, it will inject into the connecting rod (502) and the nozzle (503), so that it can cooperate with the cleaning plate (306) to blow the gas to the surface of the sound and light fish attracting component (2). When the sealing block (505) moves away from the inside of the fixed cylinder (501), the cleaning plate (306) will draw out the outside air. During the drawing process, the sound and light fish attracting component (2) can also be cleaned. S4: When the sound and light fish attracting component (2) guides the fish to migrate, the drive motor two (701) causes the lead screw (702) to rotate. The threaded block (703) will slide on the surface of the lead screw (702), while the sliding block (606) will slide along the inside of the moving plate two (704). The sliding block (606) will drive the pressing block (605) to slide on the surface of the square rod (604). The pressing block (605) will move away from the surface of the fixed block (603). The elastic element (601) in the stretched state will pull the moving plate. One (602) retracts into the interior of the bionic fishway body (1), forming a groove at the bottom of the bionic fishway body (1), allowing tired fish to enter this groove during their migration, get a moment's rest, and continue their journey after recovering their strength. After the fish completes its migration, the second motor (701) is driven again to make the lead screw (702) rotate in the opposite direction, thereby causing the extrusion block (605) to move relative to each other, thus extruding and pushing the first moving plate (602) upward, and then the first moving plate (602) can clean the inner wall of the groove.
