Laser methane sensor for mining

Abstract

The invention relates to the technical field of methane sensing accessory devices and particularly relates to a laser methane sensor for mining. The body height can be adjusted according to environmental needs, thereby improving the adaptability of the sensor; multiple whole use modes are provided, thereby reducing the use limitation of the sensor; and when the methane concentration exceeds the standard, underground managers can be conveniently reminded, thereby improving the use reliability of the sensor. The sensor provided by the invention comprises a body, a top plate, four groups of brackets and a bottom plate, wherein both the left side wall and the right side wall of the body are provided with probes, and the front side wall of the body is provided with a display screen; the four groups of brackets respectively comprise inserting columns and inserting pipes; a quickly-dismounting pipe clamp comprises a quickly-dismounting handle, a quickly-dismounting rod, a handle seat and a quickly-dismounting hoop; a group of iron sheets are arranged at the bottom end of the body; a group of magnet sheets are arranged at the top end of the top plate; the sensor also comprises a carrying rod and a massage cushion, and hook & loop fastenersmagic tapes are arranged at the top end and the bottom end of the massage cushion; and the sensor also comprises an alarm indicator lamp, an alarm speaker, a main control module, a first sensing module and a second sensing module.

Description

technical field [0001] The invention relates to the technical field of methane sensing accessory devices, in particular to a mine-used laser methane sensor. Background technique [0002] As we all know, the mining laser methane sensor is an auxiliary device used in the coal mine safety detection system to monitor the methane concentration in the coal mine roadway, mining face, goaf, return air roadway, electromechanical cavern, etc. The underground management personnel can carry it with them It can be used for portable use, and can also be used for fixed use in the above-mentioned places. It has been widely used in the field of coal mine safety detection; the existing mine-used laser methane sensor includes a body, a top plate, four sets of brackets and a bottom plate, and the tops of the four sets of brackets are respectively Installed on the left front side, right front side, left rear side and right rear side of the bottom of the top plate, the bottom ends of the four set...

It has been widely used in the field of coal mine safety detection; the existing mine-used laser methane sensor includes a body, a top plate, four sets of brackets and a bottom plate, and the tops of the four sets of brackets are respectively Installed on the left front side, right front side, left rear side and right rear side of the bottom of the top plate, the bottom ends of the four sets of brackets are all installed on the top of the bottom plate, the main body is installed on the top of the top plate, and probes are installed on the left and right sides of the main body. The front side wall of the main body is provided with a display screen; when the existing mine-used laser methane sensor is used, the methane concentration is monitored through two sets of probes, and the detection results are displayed on the display screen; the existing mine-used laser methane sensor uses It was found that the height of its body is fixed and cannot be adjusted according to the needs of the environment, resulting in poor adaptability; and its overall use method is relatively single, resulting in high limitations in use; and when its methane concentration exceeds the standard, it is not convenient to manage downhole Personnel to remind, resulting in poor reliability of its use
