Abstract

The invention relates to a rotary well cover, which comprises a well cover board (1). Six isometrical hollowed-out bodies (2) are distributed on the well cover board (1) around the axis thereof in a 360-degree and equant manner; the outer edges of the hollowed-out bodies (2) on the well cover body extend downwards to form well walls (4) arranged at intervals; a well cover rotary board (8) and a handle (9) are arranged below the well cover board (1) in a rotary manner; and a well base (15) playing a supporting role is arranged below the well cover board (1). The rotary well cover in the invention can be opened or closed in a rotary manner. The well cover plays an important role in processing a series of accidents of pedestrians falling in wells, vehicle overturn and the like. The open drainage principle of the rotary well cover lies in rotation unlike a traditional well cover which turns over the whole well cover board, thus the whole cavity can be avoided and the accidents of pedestrians falling in wells and vehicle overturn can be prevented.

Description

technical field [0001] The invention relates to a rotating manhole cover, which is convenient for rotating to open and close, and belongs to the technical field of drainage. Background technique [0002] Usually, in the case of a sudden rainstorm, waterlogging may occur in the city. At this time, sanitation workers will open the manhole cover, and this type of manhole cover is a traditional manhole cover formed of a circular integral manhole cover plate. Once the well cover is removed as a whole, an "urban black hole" will be created, and accidents such as pedestrians falling into the well and vehicles overturning are likely to occur, causing great losses to people's lives and property. In the well cover assembly structure disclosed in the Chinese patent document CN1176276C, this structure relates to a well cover assembly in which a well cover plate and a well ring seat are integrated in a permanently connected manner. The purpose of this structure is to make the well cover ...
