AI Technical Summary

Technical Problem

Due to the harsh use environment of the building drainage system, it is prone to blockage of drainage pipes, resulting in serious water accumulation on the roof, which may cause water leakage in the house.

Method used

An anti-blocking device for building water supply and drainage is designed, including house fences, hydrophobic holes, grid structures and hydrophobic structures. The blocking structure realizes automatic cleaning of the filter net through the cooperation of the filter net, chute and slider; the hydrophobic structure solves the problem of water-blooded pipe blockage through the hydrophobic pipe and the liquid-cleaning pipe.

Benefits of technology

It effectively solves the problem of roof water accumulation caused by blockage of drainage pipes, prevents water leakage in the house, and improves the reliability and stability of the drainage system.

Abstract

The anti-blocking device for building water supply and drainage comprises a house fence, drain holes are formed in the side wall of the house fence, blocking net structures are installed in the drain holes, and two sets of drain structures are installed on the outer wall of the side, away from the drain holes, of the house fence. Through the blocking net structure and the drainage structure, accumulated water appearing on the roof can be drained to the foundation from the roof through the filter net, the drainage hole, the mounting hole and the drainage pipe, and meanwhile when the filter net is blocked by too many impurities on the roof, the first telescopic rod can be driven by the water pressure of the accumulated water to move towards the interior of the second telescopic rod; and when impurities block the water outlet of the drain pipe, roof accumulated water is discharged outwards through the filter screen, the drain hole, the mounting hole, the drain pipe and the liquid distribution pipe, so that the problem of water leakage of a house building caused by serious roof accumulated water due to blockage of the drain pipe is solved.
