[0002] Inspection wells are ancillary structures of rainwater and sewage discharge pipelines for municipal road construction, residential area discharge, urban greening, drainage, etc. They are new necessary facilities that facilitate regular inspection, maintenance and dredging of sewage and drainage networks, prevent pipeline blockage, improve the leakage prevention of the connection between the pipeline and the well and the well itself, and ensure that shallow groundwater is not polluted.

[0003] In the prior art, there is a manhole for water supply and drainage network with announcement number CN219794134U, which includes: a manhole mechanism, a fixing mechanism and a ladder mechanism, wherein the fixing mechanism is located above the manhole mechanism, and the ladder mechanism is located inside the manhole mechanism. The manhole mechanism includes a manhole body, reinforcing ribs, an anti-corrosion layer, a water supply and drainage pipe body and a fixing block; the reinforcing ribs are installed inside the manhole body, the anti-corrosion layer prevents sewage from the water supply and drainage pipe body from corroding the inner wall of the manhole body, the fixing block fixes the water supply and drainage pipe body, and the inside of the manhole body can be entered through the ladder mechanism, and the fixing mechanism can fix the safety rope for going down the manhole, thereby improving the safety of the operation.

[0004] However, in the above scheme, in order to ensure the safety of the inspectors working underground, before the inspectors enter the inspection well body to work, they need to open the manhole cover to replace the harmful gases emitted by the sewage accumulated in the inspection well body with fresh air from the outside. Since the inspection well body is not equipped with a ventilation device and the inspection well body is usually located underground, the air fluidity in the inspection well body is poor, which further causes the air replacement process to take a long time. Utility Model Content
