Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an anti-sewage backflow device for urban inspection wells based on the principle of electromagnetic induction, which has the advantages of anti-sewage backflow and early warning, and solves the lack of anti-backflow function of the current inspection well cover, so in some low-lying cities The inspection well cover in the area often has the phenomenon of sewage backflow, and the probability of sewage backflow in the inspection well is also high, because the sewage poured out is often a mixture of various garbage in the city, and the pollutants contained in it are much higher than Ordinary domestic sewage, which may cause a large amount of water on the road surface, and may also pollute the environment, and will also have a greater impact on the lives of nearby residents

Abstract

The invention relates to the technical field of sewage treatment, and discloses an anti-sewage backflow device for urban inspection wells based on the principle of electromagnetic induction, which includes a well wall and a slide rail. The top of the well wall is movably connected with an inspection well cover. The water inlet pipe is movably connected, the inside of the well wall is movably connected with a sliding assembly, the outside of the sliding assembly is movably connected with an electromagnetic assembly, the inside of the well wall is fixedly connected with a magnet one, the inside of the well wall is movably connected with a baffle, and the inside of the baffle is The second magnet is fixedly connected; through the interaction between the well wall, inspection well cover, water inlet pipe, sliding assembly, electromagnetic assembly, negative pole, positive pole, and copper rod, it can achieve anti-backflow after triggering when sewage backflow occurs The structure operates, which provides prerequisites for the start of anti-backflow, and this design will only start when the sewage is poured back close to the manhole cover, which is more in line with the actual situation.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an urban manhole sewage backflow prevention device based on the principle of electromagnetic induction. Background technique [0002] Among the water pollution caused by human production activities, the water pollution caused by industry is the most serious. For example, industrial wastewater contains many pollutants and complex components. It is not only difficult to purify in water, but also difficult to treat. Industrial wastewater is the most important cause of water pollution caused by industrial pollution. It accounts for the majority of pollutants emitted by industry. The pollutants contained in industrial wastewater vary widely depending on the type of factory. Even in the same factory, the quality and quantity of pollutants contained in them are different due to different production processes. [0003] In urban construction, the sewer is an indispensable and ...
