A coal mine methane detector

Abstract

The invention discloses a coal mine methane detector and relates to the technical field of methane detection equipment. The coal mine methane detector has the advantage that threat to life security ofoperation personnel can be reduced. According to the technical scheme, the coal mine methane detector is characterized in that a mobile trolley is arranged at the bottom of a detector body; the detector body is connected with the mobile trolley through a connecting mechanism; the connecting mechanism comprises a rotating part used for driving the detector body to rotate to different angles and amoving part used for driving the detector body to move to different heights; the moving part is connected to the rotating part; the moving part comprises a first movable arm and a second movable arm which are hinged through a hinged shaft; the tail end of the second movable arm is hinged to a third movable arm through a hinged shaft. An operator does not need to get into a coal mine and an underground pipeline by himself, and the coal mine methane detector can automatically detect the content of methane in the coal mine and the underground pipeline. The possibility of danger is reduced. Threadto life security of personnel is reduced.

Description

technical field [0001] The invention relates to the technical field of methane detection equipment, in particular to a coal mine methane detector. 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. [0003] In the process of coal mining, because the coal mine has been stored underground, a lot of methane gas will be produced. During the mining process, the methane concentration in the coal mine needs to be measured. The methane detector is a ki...

Problems solved by technology

[0006] Although this waterproof coal mine methane detection instrument uses the first isolation layer and the second isolation layer respectively arranged inside the first opening and the second opening to prevent the gravel from falling into the inside of the casing when the mine is being mined, Through the cooperation of the first sponge block and the second sponge block, the effect of absorbing moist water vapor and water droplets is achieved, 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, but after a long time In the coal mines or underground pipelines used, the content of methane is high, and the operator holding the detector will easily cause suffocation, poisoning and endanger the life safety of the operator, which is a great threat to the operator
