Odorless street drainage device

Abstract

The present invention provides an odorless street drainage device which has the advantages of water drainage, no sand-dust accumulation, no obstruction and automatic isolation to the appearance of fly and mosquito and the stench discharging. The street underground sewage draining passage is installed with a square movable cover plate which is provided with a round hole at the center. A water drainage device is suspended in the round hole. A funnel, a sealing rubber ring, an inverse funnel shaped bottom valve, a spring and a porous cylinder on the water drainage device keep a connection with a certain elastic force from upper side to lower side. As the bottom is an inverse funnel shaped, and even some sand or dust exists on the street or a dust weather appears, no sand or dust will be accumulated when the dirty water flows over the water drainage device and no obstruction will occur. When the water flowing into the water drainage gets to a certain weight, the elastic force for supporting the spring of the bottom valve is overcome and the bottom valve opens downwards therefore the water flows to the underground sewage drainage passage. Because of the function of the elastic force, the inverse funnel shaped bottom valve automatically closes at any moment thereby the invention has extremely important and immediate function for isolating the appearance of the fly and mosquito and stench discharging, blocking the disease source and increasing the people health. The significance is profound.

Description

Technical field [0001] The invention relates to a drainage device for solving public health problems, especially on the street underground sewage channel, which can drain water without accumulating sand and dust, will not be blocked, and can automatically isolate mosquitoes from infestation and odorless street drainage. device. Background technique [0002] At present, the rainwater and other water on the streets in rural areas or cities are discharged into the underground sewage channel. All of them, the stench is so strong that there are poisonous gas and infectious bacteria and viruses in the stench, which seriously pollutes the air and directly enters the human respiratory tract.

Problems solved by technology

[0002] At present, the rainwater and other water on the streets in rural areas or cities are discharged into the underground sewage channel. All of them, the stench is so strong that there are poisonous gas and infectious bacteria and viruses in the stench, which seriously pollutes the air and directly enters the human respiratory tract. Mosquito-infested windows lay eggs and reproduce in the sewers, carrying infectious bacteria and viruses to people's daily food and supplies, directly and seriously endangering the health of citizens

At home, personal hygiene is kept clean, but on the street, sanitation is poor, exhaust gas is reduced, and the odor is better discharged, and a drainage window is opened 20 meters away to lead to the sewage pipe, which is no different from Tongtian toilet. Eyes You can see garbage and feces, and you can smell poisonous gas with your nose. However, they have always turned a blind eye to it and heard it without smell. So far, public health still has the disadvantage of treating the symptoms but not the root cause
