A kind of drainage device and drainage device prefabricated

Abstract

The invention provides a water draining device and a prefabricated member of the water draining device. The water draining device and the prefabricated member of the water draining device are arranged in a water draining ditch of the base side of a mine lot roadway. The water draining device comprises at least one baffle and at least one sedimentation pit which are arranged in the water draining ditch; the baffles can enclose a water flow in the water draining ditch, and at least one water guiding passageway is formed between the peripheries of the baffles and the water draining ditch. Before the baffles are washed open by water pressure, the water flow in the water draining ditch is desludged trhough the water guiding passageways, and sediments in the water guiding passageways are washed into the sedimentation pits; and when the water flow of the side faces of the upper streams of the baffles are accumulated to a certain height, the baffles are opened by the raised water pressure to enable water accumulated on the side faces of the upper streams of the baffles to be momentarily released out, and thus the sediments on the positions, at the lower streams of the baffles, of the bottom surface of the water draining ditch are washed into the sedimentation pits. The water draining device has the effect that sludge sedimentated on the bottom surface of the water draining ditch is automatically cleared away and impacted.

Description

technical field [0001] The invention relates to the technical field of mining safety, in particular to a mine drainage device and a prefabricated part of the drainage device, which have smooth drainage and are convenient for clearing mud at fixed points. Background technique [0002] With the mining of the coal mine face and the extension of the roadway, the falling slag and gravel will fall in the mine drainage ditch. The existing drainage ditches cannot be cleaned quickly and automatically, which often causes problems such as congestion of the drainage ditches and poor drainage, and the drainage capacity is limited, resulting in water overflow in the working face and roadways, which is not conducive to the safe production of coal mines, let alone Conducive to maintaining a relatively comfortable working environment. [0003] In order to prevent these problems from happening, the working face and the roadway have to clean up the silt in the ditch from time to time. The cur...

Problems solved by technology

More importantly, because the mesh structure of the drainage device can only allow water to pass through, it will not speed up the flow of water flow. When the silt continues to accumulate in front of the mesh and the mesh is blocked, it will cause poor drainage, and even work. The phenomenon of water overflow in the surface and roadway

It can be seen that the existing mine drainage structure cannot well solve the goal of mine drainage ditch silt cleaning
