The implementation principle of municipal administration safety drainage well structure of the embodiment of this application is:

when the drainage cover 3 is arranged above the drainage well body 1, the driving rod 6 is inserted into the through groove 12, so that the driving rod 6 drives the limiting rod 5 to slide out, the limiting rod 5 is positioned above the fixed plate 4, when the drainage cover 3 is required to be lifted, the fixed plate 4 is abutted against the limiting rod 5, and a person who does not know how to open the drainage cover 3 cannot easily open the drainage cover 3 from the outside of the drainage well body 1; the condition that the drainage cover 3 is missing or tilted can be improved, so that the safety of people can be well guaranteed;

knowing how to open the drain cover 3, a person can open the cover 401 first, then open the water valve 93 to make water flow into the driving rod 6, and the movable part 62 floats upwards under the buoyancy until the movable part 62 extends out of the water outlet 32, so that the person can grab the movable part 62 and then close the water valve 93, pull up the driving rod 6 until the positioning block 101 is ejected out of the driving rod 6, and then do not pull up the driving rod 6 any more. When the positioning block 101 abuts against the step surface 2, the driving rod 6 is separated from the mounting groove 11, the limiting rod 5 slides into the mounting groove 11 completely due to the elastic force of the first spring 7, the fixing plate 4 is not limited upwards any more, and the fixing plate 4 moves upwards along with the drainage cover 3 when the drainage cover 3 is lifted upwards;

before the drainage cover 3 is lifted upwards, the water valve 93 is opened to enable water to enter the water outlet pipe 20 through the water injection pipe 8, and the drainage cover 3 is lifted upwards after waiting for a few minutes to enable the annular groove 43 to be filled with water; in the lifting process, the sponge mat 45 soaked by water can wet and slightly scrape the sludge on the inner wall of the drainage well body 1, and then the scraper 46 further scrapes the sludge, so that the inner wall of the drainage well body 1 can be cleaned to a certain extent when the drainage cover 3 is opened. The working personnel can be provided with a better environment if the working personnel goes into the drainage well for operation.
