Well lid capable of achieving backward flowing
The invention discloses a well lid capable of achieving backward flowing. The well lid comprises a well base and a well lid body. A rubber layer is arranged on the upper surface of the well base. The well lid body is arranged on the rubber layer. A plurality of counter bored holes are formed in the well lid body. Threaded rods are arranged inside the counter bored holes. The lower ends of the threaded rods are connected with the well base in a screw-thread fit manner. A through hole is formed in the middle of the well lid body. A rotating rod is arranged inside the through hole. A rotating disc is arranged at the upper end of the rotating rod. The lower end of the rotating rod penetrates the well lid body to be provided with a plurality of rotating blades. The upper ends of the rotating blades are in contact fit with the well lid body. The well lid effectively prevents pedestrians from falling into a well.
