Intelligent manhole cover for solving urban air pollution

Abstract

The invention discloses an intelligent manhole cover for solving urban air pollution. The intelligent manhole cover comprises a manhole cover base and a manhole cover body arranged at the upper end ofthe manhole cover base; at least one exhaust port and a water leakage port are formed inside the manhole cover base, the edge of the water leakage port and the exhaust port extend upwards to form a boss, the exhaust boss is sequentially provided with a magnetic valve, an exhaust fan and a rainproof cover which are sequentially arranged from bottom to top and are in seamless connection with the manhole cover base; the rainproof cover is arranged at the top end of the exhaust boss and is composed of a plurality of movable blades. A nitric oxide inductor, a sulfur dioxide inductor, a PM2.5 inductor and the like are arranged inside the manhole cover body, the inductors control a magnetic valve and the rainproof cover to be turned on or off and the exhaust fan to be operated. The intelligent manhole cover has the deodorization and odor removal functions, multi-layer protection is arranged so as to avoid safety accidents, the manhole cover can be applied to air pollution places such as a road section with high automobile exhaust, a mud dust road and a chemical plant, heavy air pollution can be rapidly eliminated, and the air can be kept clean durably.

Description

technical field [0001] The invention relates to the technical field of municipal engineering devices, in particular to an intelligent manhole cover for solving urban air pollution. Background technique [0002] The sewer pipe is an important part of the urban drainage system and has become an important municipal engineering facility in urban construction; on the city streets, there are also many sewage manhole covers leading to the sewer pipe. Most of the existing sewage manhole covers are directly installed on the support of the sewer pipe by using iron steel rings or circular or rectangular circles made of concrete. The odor of the manhole is emitted directly through the sewage manhole cover, thereby affecting the air quality of the city; and the external sewage may flow into the sewer pipe along with the sediment, which may easily lead to blockage and waterlogging of the sewer pipe; in addition, the known manhole cover can only meet the drainage requirements Rainwater or...

Problems solved by technology

Most of the existing sewage manhole covers are directly installed on the support of the sewer pipe by using iron steel rings or circular or rectangular circles made of concrete. The odor of the manhole is emitted directly through the sewage manhole cover, thereby affecting the air quality of the city; and the external sewage may flow into the sewer pipe along with the sediment, which may easily lead to blockage and waterlogging of the sewer pipe; in addition, the known manhole cover can only meet the drainage requirements Rainwater or accumulated water on the ground, when the rainfall is heavy and the terrain is low, it will cause backflow of the rainwater channel, resulting in more water on the ground, and even the water in the rainwater channel will completely lift up the manhole cover, causing pedestrians and vehicles to pass by. cause safety hazard
