Protective device for municipal inspection well and operation method

Abstract

The invention relates to the technical field of inspection well covers, and discloses a protection device for a municipal inspection well and an operation method.The protection device comprises an inspection well cover body, a well cover fixing sleeve is arranged on the outer wall of the inspection well cover body, protection extending-out grooves are formed in the four corners of the bottom end of the inspection well cover body correspondingly, and protection clamping blocks are arranged in the protection extending-out grooves correspondingly; a protective rack rod is fixedly connected to one side of each protective clamping block, an induction device is arranged in the middle of the inspection well cover body and comprises an induction power generation rotor, a resistance reduction bearing is arranged at the bottom end of the outer wall of the induction power generation rotor, and an inner wall ring is arranged on the portion, located on the inner wall of the resistance reduction bearing, of the inspection well cover body. According to the inspection well cover, the top disc is arranged, so that when the top disc rotates forwards, a top rotating rod of the top disc is placed in the middle of the top end of the inspection well cover body, and at the moment, an electric drill is started, so that the top disc rotates like a top due to supporting of the top rotating rod.

Description

technical field [0001] The invention relates to the technical field of manhole covers, and more particularly to a protection device and an operation method for a municipal manhole. Background technique [0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section, from the pipeline to the ground. It is called a manhole. The entrance of the manhole is usually flush with the ground, so a cover is needed to cover the cover of the manhole, which is called manhole cover. The manhole cover is usually made of reinforced cement, metal, reinforced plastic and other materials, and the shape is round or square Mainly, on the manhole cover, it is generally necessary to indicate the purpose of the underground pipeline, the management unit and the telephone number, etc...

AI Technical Summary

Problems solved by technology

[0003] The protection device of the traditional hard manhole cover is generally on the outer surface, which is likely to cause safety hazards to passing vehicles and pedestrians, and at the same time, the manhole cover is more likely to fail. Therefore, a manhole cover protection device that can improve the protective effect of the manhole cover is needed.
