Laser methane alarm

Abstract

The invention discloses a laser methane alarm including an alarm body and a mounting groove mechanism, the mounting groove mechanism is arranged at the bottom of the alarm body, the top of the mounting groove mechanism is fixedly provided with an electric telescopic rod, the end of the electric telescopic rod is provided with a laser spectrum detection mechanism, the side edge of the laser spectrum detection is provided with a connecting rod the end part of the connecting rod is provided with a data interface; the inner wall of the mounting groove mechanism is provided with an electric sliding cover mechanism; the alarm body is internally provided with a data connection port, the data connection port and the data interface are clamped, the alarm body is internally provided with a spectrum analysis mechanism, and a controller is arranged on one side of the spectrum analysis mechanism. The electric telescopic rod can drive the laser spectrum detection mechanism to retract into the mounting groove mechanism, the mounting groove mechanism is closed by the electric sliding cover mechanism, then the content of methane in a gas can be detected, and the accuracy and quality of the detection of the content of the methane are convenient to improve.

Description

technical field [0001] The invention relates to a methane alarm, in particular to a laser methane alarm. Background technique [0002] Methane is widely distributed in nature. Methane is the simplest organic substance and the main component of natural gas, biogas, pit gas, etc., commonly known as gas. It is also the hydrocarbon with the smallest carbon content (the largest hydrogen content), and is also the main component of natural gas, biogas, oilfield gas and coal mine tunnel gas. It can be used as fuel and raw materials for the production of hydrogen, carbon black, carbon monoxide, acetylene, hydrocyanic acid and formaldehyde. Methane, with the chemical formula CH4, is the simplest hydrocarbon, which is hybridized by one carbon and four hydrogen atoms through sp3 Therefore, the structure of the methane molecule is a regular tetrahedral structure, and the bond lengths of the four bonds are the same and the bond angles are equal. Methane is a colorless, odorless gas unde...

Problems solved by technology

[0003] At present, the high-density accumulation of methane in some places is likely to cause safety hazards. Therefore, there are many methane sensors that detect the density and concentration of methane to prevent safety hazards. The gas environment in the test chamber is complex, resulting in low test accuracy, and there are certain potential safety hazards
