Municipal sewage well lid capable of automatically adjusting size of drain port according to drainage capacity

Abstract

The invention discloses a municipal sewage well lid capable of automatically adjusting the size of a drain port according to the drainage capacity, particularly relates to the technical field of municipal engineering and aims to provide a municipal sewage well lid which is capable of filtering garbage, convenient to clean and maintain and capable of automatically adjusting the size of the drain port according to the drainage capacity. The municipal sewage well lid capable of automatically adjusting the size of the drain port according to the drainage capacity comprises a well lid base, a double-hole well lid, a filter screen plate, a supporting plate, a drain port opening and closing mechanism and the like. The double-hole well lid provided with a big round hole and two small holes is movably mounted on the well lid base. The filter screen plate is fixedly mounted in the big round hole of the double-hole well lid. The municipal sewage well lid is provided with the drain port opening and closing mechanism and a stretch mechanism, can drive a rotary disk to rotate through floating of a rubber floating body to drive an equilateral baffle to slide, forms different sizes of drain portsaccording to the rotating angle and achieves the effect of adjusting the size of the drain port according to the drainage capacity.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a municipal sewage manhole cover capable of automatically adjusting the size of a drainage port according to the drainage volume. Background technique [0002] The municipal sewage manhole cover is an important device of the municipal sewage drainage system. It allows rainwater to pass through and then flow into the underground drainage pipe. However, the general manhole cover has fixed drainage holes and is relatively small. When the heavy rain comes, the water cannot be discharged into the ground in time, which is easy to cause Internal waterlogging and a lot of accumulated water affect the travel of citizens and the degree of civilization of the city. Moreover, the drains of manhole covers are easily blocked by garbage, causing the problem of not being able to drain water in time. Contents of the invention [0003] The purpose of the present invention is to pro...

Problems solved by technology

[0003] The purpose of the present invention is to provide a municipal sewage manhole cover that can filter garbage and is easy to clean and maintain, and can automatically adjust the size of the drain according to the displacement, so as to solve the problem that the general manhole cover has fixed drainage holes and is relatively small, and the water cannot be drained in time when the rainstorm comes. If it is discharged into the ground, it will easily lead to waterlogging, and there will be more water, which will affect the travel of citizens
