Problems solved by technology
[0005] In order to solve the above-mentioned technical problems, the present invention provides a coal mine underground gas control detection device to solve the problem that when the existing detection device is in use, the detection of the gas concentration at different heights of the mine is not comprehensive. Under the coal mine, the gas density ratio The air is small, and it is easy to gather at the top of the mine. If the detection is not comprehensive, it will easily cause safety accidents. When the existing detection device is in use, when detecting the gas concentration in the coal mine, the dust floating in the air adheres to the detection area. On the probe of the device, if it is not cleaned for a long time, it is easy to affect the detection of gas concentration

The invention provides a coal mine underground gas treatment and detection device, and belongs to the technical field of coal mine safety equipment. When an existing detection device is used, dust floating in air adheres to a probe of the detection device, and as a result, detection of gas concentration is affected. The invention just aims to solve the above problem. The coal mine underground gastreatment and detection device comprises a main body, an air duct and an inner plate; the bottom of a guide plate is connected with the top of the main body; a rotating rod on the side surface of theguide plate is connected with a cross rod through a belt pulley; a transverse plate is arranged in the main body, and a pull plate at the bottom of the transverse plate is mounted at the bottom end inthe main body; a rotating wheel is mounted in the main body, and a pressing plate at the side end of the rotating wheel is mounted on the side surface of a filtering part; the air duct is mounted atthe top of the main body; the cross rod on the side surface of the air duct is mounted on the side surface of the main body; and an inner plate is arranged in the main body, and a detection probe is mounted on the side surface of the inner plate. Gas concentrations at different heights are detected by using the air duct, and gas can be detected through the detection probe on the inner plate.
Description
Technical field [0001] The present invention belongs to the technical field of coal mine safety equipment, and more particularly to the gas gassation detection device under the coal mine. Background technique [0002] Coal mine gas is also known as coal seam gas, coalbed methane, mixed gas composed of methane, carbon dioxide and nitrogen from coal and surrounding rock, gas is a harmful factor in coal mine production, which is not only polluted air, but also when gas content When it is 5% ~ 16%, the fire will cause explosion, resulting in accidents, gas explosion is preventable, such as often measured gas content in the airway air, measuring gas spring, and take effective ventilation, strictly prohibit fireworks, pre-pumping Putting, mining protective layers, artificial highlights, etc., can guarantee the safety of coal mines. [0003] For example, CN20121048984.0 relates to a coal mine gas detecting device, including: air supply system, filtering system, main reactor, and four pa...
