Road well lid

Abstract

The invention provides a road well lid. The road well lid comprises a cover plate and a sinking cylinder, water leakage grooves are evenly formed in the surface of the cover plate, water leakage holes are evenly formed in the surface of the cover plate in a staggered mode with respect to the water leakage grooves, the sinking cylinder is fixed to the bottom of the cover plate, and a symmetrically-opened-closed water leakage device is installed at the position, located in the sinking cylinder, of the bottom of the cover plate; and a water retaining device capable of conducting filtering is placed in the sinking cylinder, four guiding devices are symmetrically installed on the side edge of the water retaining device, and the water retaining device is connected with the sinking cylinder in a matched mode through the guiding devices. According to the well lid, drainage is fast, through the mode that a drainage part is opened through downward movement, the top of the cover plate has a smooth and stable effect, danger caused by the drainage to traffic is effectively reduced, meanwhile, falling rainwater can be filtered through barbs, garbage accumulation at the bottom of a water well is greatly reduced, the cleaning period of the water well is prolonged, and the detachable guide devices make it convenient to take down the water retaining device for cleaning.

Description

technical field [0001] The invention relates to the field of municipal road appliances, in particular to a road well cover. Background technique [0002] Manhole covers are used to cover roads or deep wells in homes to prevent people or objects from falling. With the continuous advancement of urban construction, drainage systems have received more attention, and manhole covers are the most common drainage system equipment that we come into contact with in our lives. [0003] Traditional manhole cover is comparatively fixed for drainage aspect structure, and publication number is that CN 106592643 B Chinese invention patent just discloses a kind of municipal road manhole cover. A municipal road manhole cover is composed of a manhole cover body and a central floating cover. A through hole is provided in the middle of the manhole cover body, and a boss protruding inward is provided on the lower side wall of the through hole; the central floating cover is a floating cover whose ...

AI Technical Summary

Problems solved by technology

[0004] The municipal road manhole cover relies on floating blocks to float the central floating cover. The buoyancy of the floating block needs to be soaked in water to reflect, but the floating block of this device is fixed at the bottom of the central floating cover, and the floating block cannot fully In order to ensure the quality of the manhole cover, the central floating cover is generally made of metal or heavy materials, and the relatively small floating block cannot float the central floating cover sensitively. Use has certain security implications
