Problems solved by technology

There are some problems in this. Firstly, the quantity of detection equipment is increased, and the management is more cumbersome; secondly, wooden wedges are required to block the opening and inject mud during detection, which makes it difficult to reuse the detection pipes inserted into the coal seam. Gas detection at many locations requires a large number of detection tubes, and it takes a lot of manpower and material resources to recycle and transport these detection tubes to the ground

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...

Abstract

The invention relates to the technical field of gas detection, in particular to a coal seam gas pressure and concentration integrated detection device which is internally provided with a gas pressure detection module, a gas concentration detection module and a bag body driving and controlling module, an outer sleeve is fixedly arranged on one side of the coal seam gas pressure and concentration integrated detection device and provided with a plurality of expansion bag bodies, and an inner sleeve is fixedly arranged on the inner periphery of the outer sleeve. A gas pressure guide pipe and a gas concentration guide pipe are arranged on the inner periphery of the inner sleeve. The gas pressure guide pipe is connected with the detection pipeline of the gas pressure detection module; and the gas concentration conduit is connected with the detection pipeline of the gas concentration detection module. The expansion bag body comprises an outer side bag, the inner periphery of the outer side bag is connected with a set of fixing frames, and the inner peripheries of the set of fixing frames are jointly connected with an inner side soft ring. The gas pressure detection module and the gas concentration detection module are arranged at the detection terminal, and the gas pressure and the gas concentration are independently detected by adopting double independent pipelines, so that the detection interference is reduced, and the device can be quickly disassembled and reused.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to an integrated detection device for coal seam gas pressure and concentration. Background technique [0002] With the increase of coal mining depth, the prevention and control of gas disaster accidents has become the top priority in coal mine safety work. Before mining a new coal seam, it is necessary to detect the gas pressure and gas concentration of the coal seam. [0003] In the existing coal seam gas detection technology, the gas concentration and gas pressure are generally drilled separately, and the independent detection results are installed. There are some problems in this. Firstly, the quantity of detection equipment is increased, and the management is more cumbersome; secondly, wooden wedges are required to block the opening and inject mud during detection, which makes it difficult to reuse the detection pipes inserted into the coal seam. Gas detection at many ...
