Problems solved by technology

[0002] After the existing municipal road infrastructure manhole cover is installed, when it is necessary to open the manhole cover for related maintenance or operations, it is usually difficult or laborious to open the inner cover due to the heavy inner cover, and sometimes even requires special tools and equipment to open the manhole cover
Therefore, opening the manhole cover is labor-intensive and low in operating efficiency, which affects road or municipal construction, and is very easy to damage the manhole cover facilities, and sometimes even needs to replace the manhole cover parts, resulting in increased maintenance costs or delays in the construction period

Abstract

The invention relates to the field of infrastructure construction of municipal administration paths, in particular to a hydraulic well lid capable of being opened and closed quickly through an energy storage device. The hydraulic well lid capable of being opened and closed quickly through the energy storage device comprises electromagnetic control, manual control, the high-pressure energy storage device, an oil pump and an oil cylinder. The oil cylinder is made to work through the oil pump by means of the two manners of electromagnetic control and manual control, the high-pressure energy storage device is used for controlling working of the oil cylinder instead of battery control and manual control when battery control and manual control fail. According to the hydraulic well lid capable of being opened and closed quickly through the energy storage device, the oil cylinder is controlled through the two manner of electromagnetic control and manual control, the well lid is opened quickly, continuous operation can be achieved through the high-pressure energy storage device when both electromagnetic control and manual control fail, and it is guaranteed that the well lid can be opened under any condition; and the hydraulic well lid is ingenious in design, reasonable in structure and easy to popularize.

Description

technical field [0001] The invention relates to the field of municipal road infrastructure construction, in particular to a hydraulic well cover that can be quickly opened and closed by an energy storage device. Background technique [0002] After the existing municipal road infrastructure manhole cover is installed, when it is necessary to open the manhole cover for related maintenance or operations, it is usually difficult or laborious to open the inner cover due to the heavy inner cover, and sometimes even requires special tools and equipment to open the manhole cover. Therefore, opening the manhole cover is labor-intensive and inefficient, which affects road or municipal construction, and is very easy to damage the manhole cover facilities. Sometimes even the manhole cover parts need to be replaced, resulting in increased maintenance costs or delays in the construction period. Therefore, such problems need to be solved technically by those skilled in the art. Contents ...
