Embodiment Construction

[0029] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. see figure 1 and figure 2 , this embodiment provides a hand-held laser methane gas reflector leak detection device, including a laser reflector 1, a handheld laser methane remote detector 2, since the reflector 1 is pre-installed and fixed in the area 9 where methane gas leakage may occur, Therefore, when methane gas leakage occurs, it is convenient to find the gas leakage point. Therefore, the laser reflector 1 is installed on the position 9 where methane gas leakage may occur, and the handheld laser methane telemeter 2 includes a battery charging module 3, a voltage conversion module...

Abstract

The invention provides a handheld type laser methane gas baffle board leakage detecting device. The handheld type methane gas baffle board leakage detecting device comprises a laser baffle board and a handheld laser methane remote sensing instrument, and the laser baffle board is installed at the position where the methane gas leakage probably happens. The handheld laser methane remote sensing instrument comprises a battery charging module, a voltage converting module, a laser methane sensing module, a spectrum analyzing module, a display module and an alarm module. The laser methane sensing module comprises a laser and a laser detector. The laser of the laser methane sensing module outputs a laser signal, and the laser signal is reflected through the laser baffle board. The laser detector of the laser methane sensing module receives the laser signal reflected by the laser baffle board. The handheld type laser methane gas baffle board leakage detecting device has the advantages of being flexible, light, rapid in popularization and suitable for the industries such as petroleum, chemical engineering, coal and energy resource transportation.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a hand-held laser methane gas reflection plate leakage detection device. Background technique [0002] At present, the known hand-held laser methane detection remote measurement and alarm instrument is a long-distance measuring instrument with a laser as a detection element. This instrument is generally used for continuous measurement of methane concentration in the air. The principle of methane absorption is that there is only one hand-held methane detector. When the inspectors use the hand-held instrument for inspection, in the process of large-scale inspection, once there is a leak point, the hand-held instrument does not detect the leak point, and there is no timely warning. The alarm function brings great obstacles to the safe production of coal mines. If combustion or explosion occurs because of this, it will be an extremely serious safety accident, and it will also ...
