Waterproof coal mine methane detection instrument

Abstract

The invention provides a waterproof coal mine methane detection instrument and relates to the field of coal mine methane detection instruments. The waterproof coal mine methane detection instrument includes a casing, the left side of the casing is fixedly connected with an insertion rod, the inner bottom wall of the casing is fixedly connected with a bottom plate, and the upper surface of the bottom plate is lapped with an instrument body. The upper surface of the bottom plate is provided with a chute, and the lower surface of the instrument body is fixedly connected with a wheel bar inside the chute, and the end of the wheel bar away from the instrument body is fixedly connected with a wheel shaft. The waterproof coal mine methane detection instrument, through the first isolation layer and the second isolation layer respectively arranged inside the first opening and the second opening, prevents the gravel from falling into the inside of the shell when the mine is mining, and passes through the The first sponge block cooperates with the second sponge block to achieve the effect of absorbing moist water vapor and water droplets, and through the contraction function of the spring, the effect of driving the extrusion rod to squeeze the second sponge block to the right is achieved.

Description

technical field [0001] The invention relates to the technical field of coal mine methane detection instruments, in particular to a waterproof coal mine methane detection instrument. Background technique [0002] A coal mine refers to a place rich in coal resources, and usually refers to a factory that produces coal by underground or open-pit mining. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. The vast majority of coal mines in China are underground coal mines. The scope of coal mines includes a large area above and below ground and related facilities. In the process of coal mining, methane detection instruments will be used in mines to detect methane concentration. [00...
