Description

Technical Field

[0001] The utility model relates to the technical field of mine safety, in particular to a mine gas concentration detection device. Background Art

[0002] During coal mining, gas concentration is closely related to safety, so it is necessary to detect the gas concentration to avoid dangerous gas concentration and improve the mine safety index. By using a gas concentration detector to detect the gas concentration, it can prevent the gas concentration from reaching a dangerous value and causing dangerous accidents. When conducting the test, the air bag is pressed to inhale the air and conduct gas detection. Since the connecting pipe of the existing gas concentration detector is relatively short, it will not be possible to conduct the gas detection at the top of the mine, which makes it inconvenient to conduct gas detection at different locations in the mine. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The gas detector is connected to a connecting hose, the end of the connecting hose is fixedly connected to a connecting block, the connecting block is fixedly connected to a connecting sleeve, a connecting rod is inserted into the connecting sleeve, and the connecting hose is fixed by a winding mechanism.

[0006] Preferably, the winding mechanism includes a mounting plate, the mounting plate is fixedly connected to the gas detector, a winding disk is rotatably connected to the mounting plate via a bearing, a rotating disk is fixedly connected to the rotating shaft of the winding disk, and the rotating disk is fixed by a fixing mechanism.

[0008] Preferably, the limiting mechanism comprises a limiting sleeve, the limiting sleeve is fixedly connected to the threaded column, the limiting column is fixedly connected to the mounting plate, and the limiting column is located in the limiting sleeve.

[0009] Preferably, a bolt is threadedly connected to the connecting sleeve, and the bolt abuts against the connecting rod.

[0010] The mining gas concentration detection device proposed by the utility model has the beneficial effect of loosening the connecting hose through the winding mechanism, holding the connecting rod to place the air inlet of the connecting hose at different positions in the mine, so as to perform detection at different positions in the mine, thereby ensuring convenience during detection.

[0019] A bolt 6 is threadedly connected to the connecting sleeve 7 , and the bolt 6 abuts against the connecting rod 4 . The bolt 6 plays a role in fixing the connection between the connecting rod 4 and the connecting sleeve 7 , thereby preventing the connecting rod 4 from being separated from the connecting sleeve 4 .
