Embodiment 1
[0027] The detection terminal 1 of the coal seam gas pressure and concentration integrated detection device is equipped with a gas pressure detection module 101 , a gas concentration detection module 102 and a capsule driving control module 103 . The detection terminal 1 is fixedly connected with an outer sleeve 2, the outer sleeve 2 is divided into multiple sections, and the expansion balloon 6 is installed in the groove in the middle of the adjacent section of the outer sleeve 2.
[0028] The outer casing 2 is fixed with an inner casing 3, and between the outer casing 2 and the inner casing 3 are fixed several groups of partition ring plates 201, and each group of partition ring plates 201 forms a diversion cavity 202, and the non-tail end A group of partition ring plates 201 on the side are provided with diversion openings 203, and the bladder control module 103 is equipped with a hydraulic storage box, and the external connecting pipe of the hydraulic storage box is connect...
Embodiment 2
[0033] The coal seam gas pressure and concentration integrated detection device is used for detection. First, the coal seam to be sampled is drilled, and the outer casing 2 with the expansion capsule 6 in a contracted state is inserted into the borehole. After being inserted in place, the capsule driving and controlling module 103 is activated to hydraulically supplement the inflatable capsules 6 in the contracted state. Under the action of hydraulic pressure, the inflatable capsules 6 in the contracted state start to expand and adapt to the deformation of the wall surface of the drilled hole at their respective positions. Press the contact to form a multi-channel seal and support in the drilling channel, and then move the external positioning plate 7 to the outer base surface of the drilling position to contact, and use the reinforcement nut 8 to reinforce the external positioning plate 7, so that the entire detection device Installed at the position of gas detection, it start...
