Movable canopy device for preventing landfill area of rigid landfill from being exposed to rain

The invention provides a movable canopy device for preventing a landfill area of a rigid landfill from being exposed to rain. The device comprises a water collecting tank, a sliding rail is fixedly connected to the outer surface of the upper end of the water collecting tank, a drainage pipe is arranged on the outer surface of one side of the water collecting tank, a sliding block is slidably connected to the interior of the sliding rail, the sliding rail and the sliding block are of a T-shaped structure and matched with each other, the outer surface of the upper end of the sliding block is fixedly connected with a supporting rod, and the outer surface of the upper end of the supporting rod is fixedly connected with a rain baffle. According to the device, rainwater can be shielded, hazardous waste materials in the landfill area can be prevented from being exposed to the rainwater, after one landfill grid is filled and sealed, the canopy can be moved to the position above the next to-be-buried hazardous waste grid, the manufacturing cost of the canopy is reduced, the benefit of an enterprise is improved, and when the canopy is used in snowy days or a large number of sundries are accumulated on the surface of the canopy used for a long time, accumulated snow and sundries on the surface of the canopy can be cleaned, and the service lifetime of the device is prolonged.
