Mechanical type automatic opening and closing manhole cover and automatic opening and closing method thereof

Abstract

The invention provides a mechanical type automatic opening and closing manhole cover used for preventing sewage from overflowing and preventing rainwater from entering quantitatively and an automaticopening and closing method of the mechanical type automatic opening and closing manhole cover. The mechanical type automatic opening and closing manhole cover comprises a manhole cover body, a manholecover bracket, a water storage tank, a floating assembly, a center cleaning assembly and a quantitative water discharge assembly, wherein water inlet holes and an inspection hole are formed in the manhole cover body, the water inlet holes are uniformly distributed in the radial direction of the manhole cover body, included angles between two adjacent rows of water inlet holes are equal, the inspection hole is located in the center of the manhole cover body, the manhole cover body is fixedly connected with the upper end of the manhole cover bracket, the water storage tank is fixed in the manhole cover bracket through bumping posts, the lower surface of the manhole cover body makes contact with the upper surface of the water storage tank, first ends of edge cleaning columns are connected with the water storage tank, second ends of the edge cleaning columns are fixedly connected with the upper surface of a connecting rack, the floating assembly is connected with the water storage tank, the first end of the center cleaning assembly is connected with the bottom surface of the water storage tank, and the second end of the center cleaning assembly is connected with the quantitative waterdischarge assembly. The automatic opening and closing method of the manhole cover is also provided, and the rainwater entering and sewage discharge can be prevented.

Description

technical field [0001] The invention relates to the field of sewage inspection well covers for sewage discharge, in particular to a mechanical automatic opening and closing well cover and an automatic opening and closing method for sewage overflow prevention and rainwater quantitative prohibition. Background technique [0002] The drainage manhole cover of the urban drainage system is divided into rainwater grate and inspection well cover, both of which are indispensable, and the rainwater grate is specially used for draining rainwater. [0003] When heavy rain and heavy rain come, the existing urban drainage system cannot completely drain the rainwater in a short period of time, causing the manhole cover to be submerged in stagnant water, so part of the rainwater will flow into the city's sewage pipes through the manhole cover , It may cause the capacity overload of the sewage system, and eventually cause the sewage to leak through the manhole cover of the inspection well, ...

[0003] When heavy rain and heavy rain come, the existing urban drainage system cannot completely drain the rainwater in a short period of time, causing the manhole cover to be submerged in stagnant water, so part of the rainwater will flow into the city's sewage pipes through the manhole cover , may cause the capacity of the sewage system to be overloaded, and eventually cause the sewage to leak through the manhole cover of the inspection well, causing environmental pollution

The inspection well covers on the market generally do not have the monitoring function. After the rain stops, personnel are required to go down to the interior of the well for inspection and maintenance; The real purpose of the manhole cover and the realization of sewage discharge and rainwater ingress prevention at the same time, so there is an urgent need for an automatic opening and closing double-layer manhole cover that can prevent urban sewage from diarrhea and rainwater ingress, so as to reduce the workload of the staff
