Underwater device of sewer pit for preventing falling of people, generation of rubbish and stink smell and return of water

Abstract

The invention discloses an underwater device of a sewer pit for preventing falling of people, generation of rubbish and stink smell and return of water. The device includes a canister internally provided with a drainage hole, a cover plate is arranged on the opening of the drainage hole, the middle portion of the drainage hole protrudes inwards to form a connection boss, a mounting base is arranged on the connection boss, the inner side of the mounting base extends upwards to form an upper annular flange, the inner side of the mounting base extends downwards to form a lower annular flange, anda drainage channel is formed between the upper and lower annular flanges; a deodorized floating ball is arranged on the upper annular flange, and abuts against the inlet of the drainage channel in asealed mode under the effect of self gravity; a half floating ball is arranged below the lower annular flange, the center of the half floating ball is provided with a guiding rod, and the half floating ball can float up to seal the outlet of the drainage channel. According to the design of the underwater device, the large water discharging amount is ensured, and meanwhile, the functions of preventing falling of people, generation of the rubbish and stink smell and return of the water can be achieved, the stink smell emission and water return phenomena occurring in the sewer pits of large-scalefactories for sanitary sewage treatment, chemical and industrial pharmacy and petroleum production and the like can be fundamentally eliminated, and the underwater device has the advantage of being simple in structure and practical.

Description

technical field [0001] The invention relates to a sewer device for a sewer well, in particular to a sewer well anti-falling, anti-garbage, deodorizing and anti-water return device. Background technique [0002] In the sewer shade wells of existing cities, its sewer structure is only the shade well cover of a band of sewer holes that the sewer position is provided with. And along with increasing urbanization in recent years, urban domestic water pollution is becoming increasingly serious, which makes the sewage in the sewer all have serious odor and air pollution. But the shade well cover of existing structure does not possess anti-people falling into, anti-garbage, anti-odor and anti-water return function, this aspect makes a large amount of stinks emit through the water hole, especially in the season of hot weather, this is harmful to surrounding environment and The air has a serious impact, especially in public places such as restaurants, shopping malls, hospitals, etc.; ...

AI Technical Summary

Problems solved by technology

But the shade well cover of existing structure does not possess anti-people falling into, anti-garbage, anti-odor and anti-water return function, this aspect makes a large amount of stinks emit through the water hole, especially in the season of hot weather, this is harmful to surrounding environment and The air has a serious impact, especially in public places such as restaurants, shopping malls, hospitals, etc.; Area pollution, causing serious inconvenience to people's lives

What's more serious is that when the manhole cover is broken, it will cause people to fall and cause unnecessary injuries.
