Abstract

The invention discloses an electric well lid, which comprises a well lid, a well seat, and at least one power assisting device. The well lid and the well seat are hinged; the power assisting device comprises a fixed supporting plate fixed to the lower part of the well seat, and a screw rod arranged in the middle of an inner surface of the well lid and driven by a motor; a sliding nut on the screwrod and one end of a supporting rod are hinged; the other end of the supporting rod and the fixed supporting plate are hinged; the fixed supporting plate and one end of a first auxiliary spring are hinged; the other end of the first auxiliary spring and the well lid are hinged; the well seat and one end of at least one second auxiliary spring are hinged; and the other end of the second auxiliary spring and the well lid are hinged. According to the electric well lid provided by the invention, the well lid is driven by a motor to open and close so as to be simple in structure, low in cost, and convenient to operate and maintain; and the auxiliary springs are arranged, so that the well lid can be opened with a smaller force, the well lid can be controlled to open and close without the need for a high-power motor, and the electric control of a well lid system is ingeniously realized.

Description

technical field [0001] The invention relates to an electric well cover. Background technique [0002] Urban sewer manhole covers are heavy, and most of the existing urban sewer pipeline manhole covers are hydraulic power-assisted manhole covers, which have complex structures, high costs, and inconvenient maintenance. With the popularization of urban comprehensive pipeline integration, manhole covers also have the function of escape openings. The hydraulic assisted manhole covers are cumbersome to open through manual hydraulic methods, and the efficiency is too low to meet the needs of emergency escape functions. There are also researchers who try to open the manhole cover electrically, but the power of the motor is required to be very large, and the boosting effect cannot be guaranteed. Contents of the invention [0003] The invention aims to provide an electric well cover, which simplifies the structure of the well cover system, reduces the cost of the well cover system,...
