Embodiment 1

[0040] see figure 1, a coalbed methane detection device capable of sampling soil at different depths in a well according to the present invention includes a support frame 01 and a wellway 03, and a reel 06 is rotatably connected to the center of the inner side of the support frame 01 near the top. The outer surface of 06 is wound with a connecting rope 09, one end of the connecting rope 09 is fixedly connected with a butt joint 10, and the bottom end of the butt joint 10 is fixedly connected with a fixed block main body 11, and a cavity is provided in the center of the inner cavity of the fixed block main body 11; A power supply unit 12 is installed in the cavity, and the left and right sides of the fixed block main body 11 are fixedly connected with fixed block flanks 13, and the two fixed block flanks 13 are far away from each other and are fixedly installed with electric telescopic rods 14 near the top and bottom. The two sets of electric telescopic rods 14 are provided wit...

Embodiment 2

[0042] see Figure 5 , 6 , 7, the outer surface of the butt joint 10 is fixedly connected with four connecting pieces around the ring at equal distances, and the bottom surfaces of the four connecting pieces are all fixedly connected with the top surface of the fixed block main body 11. This structure is set so that the distance between the butt joint 10 and the fixed block main body 11 The connection between the two sets of electric telescopic rods 14 is fixedly connected to the first pair of insertion rods 23 at the ends far away from each other, and the two sampling frames 15 are fixedly connected to one side and corresponding to the first pair of insertion rods 23. There is a first docking socket 22 that fits with the first docking rod 23, and the first docking rod 23 is inserted into the first docking socket 22 and fixed by fixing screws. This structure allows the staff to better sample The frame 15 is disassembled and installed, or the sampling frame 15 of different len...

Embodiment 3

[0044] see image 3 The bottom of the fixed block main body 11 close to the edge is fixedly connected with three legs 17 equidistant around the ring. 11 can be better placed on the placement board 04; the central position of the bottom of the fixed block main body 11 is fixedly equipped with a light 19, and the bottoms of the two fixed block flanks 13 are fixedly installed with a camera 16. This structure is set so that the staff can Through the camera 16 and the lighting lamp 19, the situation inside the shaft 03 can be better observed; the central position of the bottom of the lighting lamp 19 is fixedly equipped with a gas detector 18, and the front of the gas detector 18 is provided with an air inlet near the bottom. The structural setting allows the staff to better detect the gas in the shaft 03; the position between the inner side of the support frame 01 near the front and back and near the bottom is fixedly connected with the crossbar 02, and the top of the two crossbar...

Abstract

The invention relates to the technical field of coal bed gas detection, and particularly discloses a coal bed gas detection device capable of sampling soil at different depths in a well, the coal bed gas detection device comprises a support frame and a well, a winding reel is rotatably connected to the central position, close to the top, between the inner sides of the support frame, and a connecting rope is wound on the outer surface of the winding reel; one end of the connecting rope is fixedly connected with a butt joint, and the bottom end of the butt joint is fixedly connected with a fixing block main body; according to the device, through the arranged connecting rope and marking nodes, a worker can better control the placing depth, meanwhile, an arranged electric telescopic rod is matched with a sampling frame, soil at different depths in a well is better sampled, meanwhile, by means of a driving motor and a winding reel, the device is more rapid and labor-saving to place and lift, and the device is more convenient to use. The problem that soil of different depths in a well cannot be effectively sampled when logging is carried out in a traditional coal bed gas detection step is solved.

Description

technical field [0001] The invention relates to the technical field of coalbed methane detection, in particular to a coalbed methane detection device capable of sampling soil at different depths in wells. Background technique [0002] Coalbed methane is a gas resource that is associated and symbiotic with coal. It refers to hydrocarbon gas stored in coal seams, with methane as the main component, and belongs to unconventional natural gas; coalbed methane is mainly adsorbed on the surface of coal matrix particles, and part of it is free in coal pores. Hydrocarbon gas neutralized or dissolved in coal seam water is an associated mineral resource of coal and a clean, high-quality energy and chemical raw material that has risen internationally in the past 10 to 20 years. [0003] At present, when conducting coalbed methane exploration, it is generally necessary to conduct field geological exploration first, then seismic exploration, then drilling, and finally logging and a series...
