Drainage device for coal mine excavating roadway

Abstract

The invention relates to the technical field of coal mine excavation, in particular to a drainage device for a coal mine excavating roadway. The drainage device for the coal mine excavating roadway comprises a device main body, a pneumatic drainage unit and a liquid level control switch; both the pneumatic drainage unit and the liquid level control switch are fixedly mounted on the device main body; the liquid level control switch is matched with the pneumatic drainage unit; and the device main body comprises a square frame, four supporting legs and a handle. The drainage device for the coal mine excavating roadway works by taking compressed air as a power source and can avoid using a power supply to drive to work so as to eliminate a potential safety hazard that an electric spark is easily produced in a working process, and then gas explosion is avoided; therefore, the drainage device for the coal mine excavating roadway is high in safety performance, is particularly suitable for coalmine drainage, can be automatically started and stopped in a working process, is easy to operate, meanwhile, can reduce the energy consumption, and can also effectively prolong the service life; thenoise is low during working; and the noise pollution produced during long-term work can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of coal mine excavation, more specifically, it relates to a coal mine excavation roadway drainage device. Background technique [0002] Due to the rich gas in underground coal mines, there is a risk of gas explosion, and the failure of electrical equipment can cause gas explosions. In principle, the use of electrical equipment should be minimized underground. The excavation roadway drainage device in the prior art requires a power source to work, and it is easy to generate electric sparks during the working process, which is easy to cause gas explosion, resulting in poor safety performance, and is especially not suitable for coal mine drainage; secondly, in the prior art The excavation roadway drainage device in the prior art cannot realize automatic start and stop in the working process, the operation is more troublesome, and at the same time, the energy consumption is relatively large, which seriously affe...
