Novel water drain pipe device

Abstract

The invention discloses a novel water drain pipe device, and relates to the technical field of water drain pipes. The novel water drain pipe device comprises a U-shaped pipe, and is characterized in that the left side of the U-shaped pipe is communicated with a water outlet pipe; one end, away from the water outlet pipe, of the U-shaped pipe is communicated with a water inlet pipe; one end, near the exterior, of each of the water outlet pipe and the water inlet pipe is respectively communicated with a flange sleeve pipe; rubber sealing rings are respectively arranged at both ends of each flange sleeve pipe; the lowest point at the inner wall of the water outlet pipe is higher than the highest point at the inner wall of the lowest part of the U-shaped pipe, and the higher part is equal to 1.5 times of the inner diameter of the U-shaped pipe; the lowest point of the water inlet pipe is higher than the lowest point of the water outlet pipe. The novel water drain pipe device has the advantages that the blockage of a pipeline due to silt settlement is greatly relieved; the service life of the pipeline is prolonged; the detachment and replacement are convenient; the sealing property andstability at the connecting part are improved; the air is blocked from entering a coal bed via the pipeline; the possibility of gas explosion is greatly reduced; the development of safety coal production industry is promoted.

Description

technical field [0001] The invention relates to the technical field of drainage pipes, in particular to a novel drainage pipe device. Background technique [0002] my country has always been a big consumer of coal resources, and coal resources play an important role in our country. In the process of coal mining, gas explosion has always been a very serious problem. Once a gas explosion occurs, its economic and social harm will be very serious. When coal and gas come into contact with a sufficient amount of air, gas explosion accidents are very likely to occur, so isolating air from entering has always been an important issue in coal mining. The device effectively prevents the air from entering the coal seam area through the drainage pipe, and effectively improves the safety factor of coal mining.
