Problems solved by technology

[0003] However, because the detection equipment is used for detection with a handheld instrument, and different gases inside the coal mine form stratification in the air, the handheld instrument can only detect the gas concentration at a single height, resulting in inaccurate gas concentration detection

Embodiment 1

[0028] Such as Figure 1-3 As shown, the operating environment detection equipment for coal mine accident prevention and control includes a detection device 1, a connecting pipe 2 is fixed on the right end of the detection device 1, a mixing device 3 is fixed on the upper end of the connecting pipe 2, and an exhaust fan 4 is fixed on the right end of the mixing device 3 , the right end of exhaust fan 4 is fixed with air inlet pipe 5, and the right end of air inlet pipe 5 is fixed with quantitative air intake device 6, and the lower end of air inlet pipe 5 is fixed with cleaning device 7, and quantitative air intake device 6 comprises electromagnetic valve 61, electromagnetic The lower end of the valve 61 is fixed with a box body 64, the inner surface of the box body 64 is slidably connected with an extrusion plate 65, and the upper end of the extrusion plate 65 is connected with a screw 63 through thread rotation, and the right side of the screw rod 63 is at the upper end of th...

Embodiment 2

[0031] Such as Figure 1-5 As shown, the operating environment detection equipment for coal mine accident prevention and control includes a detection device 1, a connecting pipe 2 is fixed on the right end of the detection device 1, a mixing device 3 is fixed on the upper end of the connecting pipe 2, and an exhaust fan 4 is fixed on the right end of the mixing device 3 , the right end of exhaust fan 4 is fixed with air inlet pipe 5, and the right end of air inlet pipe 5 is fixed with quantitative intake device 6, and the lower end of air inlet pipe 5 is fixed with cleaning device 7, and mixing device 3 comprises mixing box 32, mixing box 32 The inner surface of the inner surface is rotatably connected with a rotating rod 31, and the outer surface of the rotating rod 31 is fixed with a stirring impeller 33.

[0032] The exhaust fan 4 draws the gas inside the air inlet pipe 5 into the mixing box 32, and the high-speed gas enters the mixing box 32 to drive the stirring impeller ...

Embodiment 3

[0034] Such as Figure 1-6 As shown, the operating environment detection equipment for coal mine accident prevention and control includes a detection device 1, a connecting pipe 2 is fixed on the right end of the detection device 1, a mixing device 3 is fixed on the upper end of the connecting pipe 2, and an exhaust fan 4 is fixed on the right end of the mixing device 3 , the right end of exhaust fan 4 is fixed with air inlet pipe 5, and the right end of air inlet pipe 5 is fixed with quantitative air intake device 6, and the lower end of air inlet pipe 5 is fixed with cleaning device 7, and cleaning device 7 comprises cleaning box 72, cleaning box 72 The left end is fixed with water inlet pipe 71.

[0035]Because the air in the coal mine production contains a large amount of coal powder and dust, after the dust enters the box body 64 through the intake pipe 66, it will follow the pipe and adhere to the inner pipe wall of each pipe, and connect the power supply of the solenoid...

Abstract

The invention provides coal mine accident prevention and control operation environment detection equipment which comprises a detection device, a communicating pipe is fixed to the right end of the detection device, a mixing device is fixed to the upper end of the communicating pipe, an exhaust fan is fixed to the right end of the mixing device, and an air inlet pipe is fixed to the right end of the exhaust fan. A quantitative gas inlet device is fixed to the right end of the air inlet pipe, a cleaning device is fixed to the lower end of the air inlet pipe, quantitative gas at different heightscan be well collected through the quantitative gas inlet device, and therefore the different gas contents can be detected, and when the gas content at a certain height needs to be measured, the rotating nut is rotated to be not in contact with the plate body, so that the screw can be prevented from driving the plate body to move up and down, the height of air entering the plate body can be well adjusted, and the content of gas in a coal mine operation environment is kept within a safe range.

Description

technical field [0001] The invention relates to the field of testing equipment, in particular to working environment testing equipment and a testing method for coal mine accident prevention and control. Background technique [0002] A gas detector is an instrumentation tool for gas leakage concentration detection, including: portable gas detectors, handheld gas detectors, fixed gas detectors, online gas detectors, etc., mainly using gas sensors to detect The type of gas that exists, the gas sensor is a sensor used to detect the composition and content of the gas. [0003] However, because the detection equipment is used for detection by hand-held instruments, and different gases in the coal mine form stratification in the air, the hand-held instruments can only detect the gas concentration at a single height, resulting in inaccurate gas concentration detection. Contents of the invention [0004] The object of the present invention is to provide a working environment detec...
