Abstract

The invention relates to an automatic hydraulic well cover capable of being opened by overturning. The hydraulic well cover mainly comprises a base (1), hinge shafts (2), (3), (6), (7) and (11), connecting rods (4) and (5), an upper well cover (8), a sealing ring (9) and a hydraulic oil cylinder (10). The well cover can be opened and closed locally manually, locally automatically or remotely. Meanwhile, the well cover also water-resistant, fire-resistant and self-locking anti-theft functions.

Description

technical field [0001] The invention relates to the field of municipal road infrastructure construction, in particular to an automatic hydraulic manhole cover that is turned over and opened. Background technique [0002] The comprehensive pipeline corridor is the comprehensive pipeline corridor of the underground city. That is to build a tunnel space underground in the city, integrate various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage, and set up special inspection ports, hoisting ports and monitoring systems, and implement unified planning, unified design, Unified construction and management is an important infrastructure and "lifeline" to ensure the operation of the city. With the improvement of industrial automation, the manhole cover of the inspection port of the pipe gallery needs to be connected to the network information platform to achieve unified remote control. Therefore, an automatic hydraulic manhole cover t...
