A coal mine underground mobile gas drainage equipment

Abstract

The invention provides a coal mine underground mobile gas drainage equipment, including a movable base, a movable brake wheel, a storage tank, a extraction device, a connecting pipe, a first guide pipe, a rotatable fixed sealing fixed-point suction hood structure, a detachable automatic The conveying pipe structure can support the overlaid protective frame structure, rotatably support the fixed rod structure, the suction fan, the support plate, the control box, the PLC, the power switch and the display screen, and the mobile brake wheels are respectively bolted to the lower end of the mobile base Four corner positions; the storage grooves are respectively opened at the four corner positions of the mobile base. The arrangement of the metal hose, the suction hood, the positioning pipe, the first fixing plate and the socket hole in the present invention is beneficial to drive the suction hood to rotate by rotating the metal hose during use, and is fixed by the first fixing plate On the inner wall of the mine, and then make the suction hood correspond to the appropriate position to facilitate the positioning and extraction work during the process of gas extraction.

Description

technical field [0001] The invention belongs to the technical field of coal mine equipment, and in particular relates to a coal mine underground mobile gas drainage equipment. Background technique [0002] In the early stage of coal accumulation of ancient plants, cellulose and organic matter were decomposed by anaerobic bacteria. In the high temperature and high pressure environment, at the same time as coal formation, due to physical and chemical effects, gas and gas continued to be generated. It is a colorless and odorless gas, but sometimes you can smell an apple-like fragrance. This is because the aromatic hydrocarbon gas is gushing out at the same time as the gas. The relative density of the gas to the air is 0.554. The density is 0.716kg / m3, the permeability of gas is 1.6 times that of air, it is insoluble in water, does not support combustion and cannot maintain breathing. Gas exists in free state and sorption state in coal body or surrounding rock. When coal mines...
