A spring 72 is installed in the sleeve 71, one end of the spring 72 is fixedly connected with the inner wall of the sleeve 71, the other end of the spring 72 is fixedly connected with the shifting tooth 7, and the spring 72 enables the shifting tooth 7 to always have a tendency of moving away from the driving rod 62.

When the moving rod 43 moves downwards, the driving rod 62 moves vertically upwards, and at this time, the upper surface of the shifting tooth 7 is attached to the teeth of the spur gear 442 and drives the spur gear 442 to rotate, thereby driving the rotating shaft 44 to rotate; when the moving rod 43 moves upward to reset, the driving rod 62 moves vertically downward, at this time, the lower surface of the dialing tooth 7 is attached to the spur gear 442, because the lower surface of the dialing tooth 7 is arranged in an arc surface, the arc surface of the dialing tooth 7 is in contact with the spur gear 442, when the driving rod 62 moves downward, a contact point between the dialing tooth 7 and the spur gear 442 moves along the arc surface, and the spur gear 442 extrudes the dialing tooth 7 into the sleeve 71. So that the driving rod 62 can move vertically downward without rotating the spur gear 442 when the moving rod 43 moves upward to be reset.

Since the plurality of the moving rods 43 are installed between the two side walls of the accommodating groove 11, when a vehicle or a pedestrian is located at different positions in the culvert, the moving rods 43 at different positions can be driven to move, and further the rotating shaft 44 is driven to rotate, so that the generator 41 is driven to operate. When a plurality of pedestrians or vehicles are in the culvert, the moving rods 43 at different positions are driven to move, and at this time, when one moving rod 43 moves downwards, the other moving rod 43 just moves upwards to reset, and because the moving rod 43 moves upwards to reset, the driving rod 62 can move vertically downwards and cannot drive the spur gear 442 to rotate, so that the normal operation of the generator 41 is not influenced.

The implementation principle of the culvert anti-blocking drainage structure in the embodiment of the application is as follows: when a pedestrian or a vehicle moves on the road surface in the tunnel body 1, the moving rod 43 is driven to vertically move downwards, the displacement of the moving rod 43 is amplified through the shifting rod 61 and then transmitted to the driving rod 62, the driving rod 62 vertically moves upwards, the plurality of shifting teeth 7 on the driving rod 62 are meshed with the straight gear 442 and drive the straight gear 442 to rotate, so that the rotating shaft 44 is driven to rotate, the rotating shaft 44 drives the generator 41 to run for generating power, the electric energy generated by the generator 41 is transmitted to the storage battery 42 for storage, and the storage battery 42 supplies power to the driving motor 32 and the sewage pump 22. The driving motor 32 drives the steel wire brush plate 34 to clean the surface of the grating 21, so that the grating 21 is prevented from being blocked by sundries to influence the drainage of the drainage ditch 2. Meanwhile, the sewage pump 22 washes sand and desilts the inside of the drainage ditch 2 through the flushing pipe 23, and the phenomenon that the sediment is deposited in the drainage ditch 2 to affect drainage of the culvert is avoided.
