Abstract

The invention provides a water discharging device of a gas extraction pipeline. The water discharging device comprises a water bag, wherein an air inlet communicated with the outside and a water inlet connected to the bottom of a gas extraction pipeline are arranged at the upper part of the water bag; a water discharging opening is further arranged at the bottom of the water bag; a water outlet, a gas inlet and the water discharging opening are provided with valves; control ends of the water outlet, the gas inlet and the water discharging opening are connected to a controller and the controller is further connected with a water level sensor arranged inside the water bag; when the water level in the water bag is higher than a first pre-set height, the controller sequentially controls the valves of the water inlet and the water outlet to be opened, controls the valve of the air inlet to be opened and controls the valve of the water discharging opening to be opened; when the water level in the water bag is higher than a second pre-set height, the controller sequentially controls the valve of the water discharging opening to be closed, controls the valve of the air inlet to be closed and controls the valve of the water inlet to be opened; and the first pre-set height is greater than the second pre-set height. The water discharging device of the gas extraction pipeline can automatically release deposited water in the extraction pipeline.

Description

technical field

[0001] The invention relates to mine equipment, in particular to a water release device for a gas extraction pipeline. Background technique

[0002] Gas drainage is an important means of underground gas control, but in the process of drainage, not only the gas in the borehole will be pumped out, but also the accumulated water in the borehole will be pumped out. If the problem of water accumulation in the gas drainage pipeline is not completely resolved, it will impose a burden on the gas drainage system of the mine, increasing the extraction power of the extraction pump and the negative pressure capacity of the extraction system. Contents of the invention

[0003] The object of the present invention is to provide a water release device for gas extraction pipeline, which is used for releasing accumulated water in the extraction pipeline.

[0004] The invention provides a gas extraction pipeline water release device, comprising: a water bag, the upper part o...
