Water drainage device

Abstract

The invention discloses a water drainage device. The water drainage device comprises a water drainage hole, wherein the two ends of the water drainage hole are movably connected with a goaf and a bentpipe correspondingly, a sleeve is arranged in the water drainage hole in a sleeved mode, a grating is movably connected to the first end of the sleeve, the second end of the sleeve is movably connected with the first end of the bent pipe, a water drainage opening is formed in the second end of the bent pipe, and the water drainage opening is connected with a pipe clamp; the pipe clamp comprises afixing piece and a supporting piece, the fixing piece is a solid circle fixing piece, the supporting piece is fixedly connected to one end of the fixing piece, the first end of the water drainage opening is fixedly connected with the first end of the pipe clamp, and the second end of the water drainage opening is movably connected with the second end of the pipe clamp through a spring piece; andthe bent pipe is a right-angle bent pipe, a supporting frame is arranged on the outer side wall of the bent pipe close to the ground, and the spring piece is movably connected between the supporting frame and the supporting piece. The first end of the sleeve is provided with the grating, the bent pipe is the right-angle bent pipe, the pipe clamp are connected with the bent pipe through the springpiece, the pipe clamp can be automatically controlled to be opened or closed according to actual conditions, the congestion of broken gangue or rock powder on the bent pipe is reduced, and the probability of incapability of normally water draining caused by the congestion is reduced.

Description

technical field [0001] The present application relates to the field of mining equipment, in particular to a drainage device. Background technique [0002] During the mining and excavation process, the mine may be close to the aquifer, and at the same time, the original formation will be damaged after mining, resulting in the destruction of fissure water or karst water system, which will gather in the mining space, resulting in a large amount of water accumulation in the underground production system of the mine. Large amounts of standing water tend to block systems, damage roadways, and even flood wells, causing loss of property and lives. In order to timely discharge mine water to the ground, in the mine drainage system, drain holes are often left in the goaf. [0003] In the traditional mine drainage system, the upper end of the weep hole is inserted into the goaf, and the lower end of the weep hole is movably connected to the U-shaped pipe. During use, the water in the ...
