Sealed type water drain grate

Abstract

The invention discloses a sealing type sewer strainer which comprises a body and a dustpan-shaped sealing disc which is hinged with one side of the underside of the strainer; an upper flat mouth of the sealing disc is matched with a fixed frame of the strainer; the rear end of the sealing disc is fixed with a cantilever balance weight; the moment of the balance weight is larger than the dead weight of the sealing disc and is smaller than the gross weight of the sealing disc filled with water. In normal time, the sealing disc is supported under the strainer by the moment of the balance weight and achieves the functions of preventing odor from escaping upwards. In raining, firstly, rainwater flows to the sealing disc and is accumulated; when the sealing disc is nearly filled with rainwater, the sealing disc exceeds the moment of the cantilever balance weight and is overturned to release the accumulated rainwater; as long as the rainwater continuously flows to the sealing disc, the sealing disc can continuously keep an overturning state; and when the rainwater is stopped, the sealing disc is restored to an original state. Therefore, the sealing type sewer strainer solves the sealing problem of a sewer and purifies atmospheric environment.

Description

technical field [0001] The present invention relates to a sewer grate. Background technique [0002] At present, the sewers (or sewers) below the streets, roads and other roads in some towns are not fully enclosed, and there is no iron grate at a certain distance. The sundries are washed into the sewer, because the grate or hole of the grate is open, so the smell of the sewer will emerge from the grate, and the stench is suffocating, affecting the air quality. Contents of the invention [0003] The present invention proposes a sealed sewer grate for solving the problem of foul smell from the current sewer grate. [0004] The technical scheme of the present invention is that it includes the existing grate body, and is characterized in that a dustpan-shaped sealing disc is hinged on one side below the grate, the upper flat opening of the sealing disc matches the solid frame of the grate, and the rear of the sealing disc A cantilever counterweight is fixed at the end, and t...
