Indoor drainage system capable of prevention sewage from pouring

Abstract

The invention discloses an indoor drainage system for preventing back flow of sewage, which is applicable to residential buildings, office buildings, commercial buildings, hotels, auditoriums, etc. The indoor drainage system mainly comprises a drainage stand pipe and a stack vent thereof, a cross junction, a drainage elbow of 90 degrees, a discharge pipe, an overflow pipe (the pipe bottom is about 150mm lower than the indoor ground level), an indoor overflow horizontal pipe, an overflow drainage tee, a blind flange (positioned at staircases or outdoors), a transparent observation pipe, an overflow telemetering light control probe, an electrical control probe, an overflow discharge pipe, a horizontal drainage branch pipe, sanitary ware, an overflow stand pipe and a stack vent thereof. When some place of the drainage stand pipe or the discharge pipe is blocked, the sewage is automatically discharged from the overflow pipe and not returned indoors. When the pipe is cleared, the blind flange is taken off, a spring soft shaft of an electric cleaning machine is rotatably inserted into the pipe mount and the pipe can be cleaned in short time. As the cleaning machine is not arranged indoors, the pipe can be periodically cleaned for blockage prevention. The telemetering device can timely discover blockage of the drainage pipe.

Description

technical field [0001] The present invention relates to the benign application of internal drainage systems of buildings such as residential buildings, office buildings, commercial buildings, hotels and halls, and convenient clearing facilities when pipelines are blocked. The method of clearing the internal drainage standpipe and discharge pipe outside the living room, so as to ensure the tranquility and sanitation of the living room. Background technique [0002] In real life, no matter at home or abroad, accidents of blocked drainage pipes inside buildings often occur. There are three types: [0003] The first kind of clogging accident is the clogging of the water sealing device (trap) of the sanitary ware and the clogging of the horizontal branch pipe of sewage drainage. This kind of blockage is caused by each family. It is easy to find out in time to stop the water and clean it up in time. Therefore, it rarely causes the disaster of sewage overflowing into the living ro...

Problems solved by technology

[0007] The third kind of clogging accident is that debris enters the sewage horizontal (with a slope of about 2%) discharge pipe near the 90° elbow at the junction of the sewage drainage standpipe and the sewage discharge pipe and beyond

At the beginning, people only knew to emphasize the careful use of fire, but later found that it is difficult to completely prevent fires even with meticulous and strict fire prevention measures, so people invented fire protection technology, which is now used in high-end buildings and public buildings, such as airports, stadiums, stations, etc. developed to a very complex and expensive level of modernization
