A bottom plate is installed below the cylinder through a telescopic rod. A filter cartridge is installed on the surface of the bottom plate. At the same time, the sliding frame installed above the filter cartridge is slidably connected to the chute inside the cylinder body. Therefore, under the action of the cylinder and the telescopic rod, the filter cartridge can move vertically inside the cylinder body. The downward movement of the filter cartridge causes the bottom plate to leave the cylinder body, so that the coalbed methane can enter the inside of the cylinder body after being filtered by the filter cartridge, and then enter the measuring instrument through the connecting pipe and the fan for measurement. After the measurement is completed, the bottom plate can block the cylinder body under the action of the cylinder and the telescopic rod, avoiding damage caused by coal slag in the coalbed methane entering the measuring instrument, thereby improving the service life of the measuring device.

[0016] 2. The methane content measuring device for coalbed methane exploration. An adjustment mechanism is installed between the mounting seat and the mounting frame. A motor is installed inside the housing of the adjustment mechanism, and the motor can drive the screw to rotate. Since the screw is threadedly connected inside the sleeve, and the sleeve is fixedly installed with the mounting frame, the distance between the mounting seat and the mounting frame can be adjusted through the rotation of the screw and the linkage between the sleeve and the screw, thereby realizing the height adjustment of the measuring mechanism.

Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 , in this implementation: A methane content measuring device for coalbed methane exploration includes a mounting base 1. A regulating mechanism 2 is provided below the mounting base 1 to adjust the mounting height of the measuring mechanism 4. An installation bracket 3 is provided below the regulating mechanism 2. A measuring mechanism 4 is provided on one side below the installation bracket 3. A connecting hole 5 is provided inside the measuring mechanism 4. A filtering mechanism 6 is provided below the installation bracket 3. A sliding groove 7 is provided below the measuring mechanism 4;

[0025] The filtering mechanism 6 includes a cylinder 61, a telescopic rod 62, a bottom plate 63, a filter cartridge 64 and a sliding bracket 65. A telescopic rod 62 is fixedly installed below the cylinder 61. A filter cartridge 64 is fixedly installed on the surface of the bottom plate 63. A sliding bracket 65 is fixedly installed on the surface of the filter cartridge 64.

[0026] Please refer to Figure 1 and Figure 2 , in this embodiment, the adjusting mechanism 2 includes a housing 21, a motor 22, a screw 23 and a sleeve 24. A motor 22 is fixedly installed inside the housing 21. A sleeve 24 is threadedly connected to the outside of the screw 23.

[0027] In the above embodiment, the housing 21 can be used to install and fix the motor 22, and the threaded connection between the screw 23 and the sleeve 24 enables the distance between the mounting bracket 3 and the mounting base 1 to be adjusted.

[0028] Specifically, the housing 21 is fixedly installed with the mounting base 1, the sleeve 24 is fixedly installed on the upper surface of the mounting bracket 3, and the motor 22 is drivingly connected to the screw 23.

[0029] The rotation of the screw rod 23 can be achieved through the motor 22 inside the sleeve 24. Since the motor 22 is installed inside the housing 21, the rotation of the screw rod 23 can cause the sleeve 24 to move vertically, thereby realizing the adjustment of the mounting bracket 3 and the measuring mechanism 4. The specific structure of the measuring mechanism 4 will be described in detail below.

[0030] Please refer to Figure 1 、 Figure 3 and Figure 5 In this embodiment, the measuring mechanism 4 includes a frame 41, a measuring instrument 42, a cylinder body 43, a blower 44, and a connecting pipe 45. The measuring instrument 42 is fixedly installed inside the frame 41. One side of the cylinder body 43 is fixedly connected to the connecting pipe 45, and one side of the connecting pipe 45 is fixedly connected to the blower 44.

[0031] In the above implementation, the measuring instrument 42 can be installed and fixed to the mounting bracket 3 through the frame 41. The connecting pipe 45 installed on one side of the cylinder body 43 is fixedly connected to the blower 44. Therefore, when the blower 44 is started, the external coalbed methane can be sent into the measuring instrument 42 through the cylinder body 43 and the connecting pipe 45 to measure the methane content in the coalbed methane.

[0032] Furthermore, the frame 41 is fixedly installed on both sides below the mounting bracket 3. The intake pipe of the measuring instrument 42 is fixedly connected to the blower 44, and one end of the connecting pipe 45 is fixedly connected to the connecting hole 5.

[0033] Since the connecting hole 5 penetrates the cylinder body 43, the coalbed methane inside the cylinder body 43 can be sent to the inside of the measuring instrument 42 through the connecting hole 5 and the connecting pipe 45 for methane content detection.

[0034] Please refer to Figure 1 、 Figure 3 and Figure 4 In this embodiment, the cylinders 61 are fixedly installed on both sides below the mounting bracket 3. The filter cartridge 64 is fixedly connected between the bottom plate 63 and the sliding frame 65. The telescopic rods 62 are fixedly connected above the two side surfaces of the bottom plate 63, and the sliding frame 65 is slidably connected to the chute 7.

[0035] In the above embodiment, under the action of the cylinders 61, the telescopic rods 62 can drive the filter cartridge 64 to move vertically inside the cylinder body 43 through the bottom plate 63. The sliding frame 65 above the filter cartridge 64 slides inside the chute 7. The upward movement of the bottom plate 63 can block the air inlet of the cylinder body 43, and the downward movement of the bottom plate 63 can open the cylinder body 43 and filter the coal slag in the coalbed methane through the filter cartridge 64 to prevent the coal slag from entering the measuring mechanism 4 along with the coalbed methane.

[0036] It should be additionally noted that fixing bolts are sleeved inside the four corners of the upper surface of the mounting base 1, and two sets of adjusting mechanisms 2 are provided. The adjusting mechanisms 2 are fixedly connected to both sides between the mounting base 1 and the mounting frame 3.

[0037] The measuring device can be installed and fixed through the fixing bolts inside the mounting base 1, and the adjusting mechanism 2 can be used to adjust the height of the measuring mechanism 4, so as to meet different installation and use requirements.

[0038] The working principle and usage process of the present utility model are as follows: After the operator installs and fixes the whole measuring device by passing the fixing bolts through the mounting base 1, the motor 22 is started to drive the screw rod 23 to rotate inside the sleeve 24. Since the screw rod 23 is threadedly connected to the sleeve 24, the mounting frame 3 can drive the measuring mechanism 4 to move down to an appropriate height and then it can be used. When it is necessary to detect the methane content in coalbed methane, only need to start the cylinder 61 so that the telescopic rod 62 drives the bottom plate 63 to move downward, and then the filter cylinder 64 is moved outwards from the inside of the cylinder body 43 to an appropriate position. Then, by starting the fan 44, the external coalbed methane passes through the filter cylinder 64 to filter the coal cinder in the coalbed methane and then enters the inside of the cylinder body 43. The connecting holes 5 installed inside the cylinder body 43 can send the coalbed methane into the measuring instrument 42 through the connecting pipe 45 and the fan 44 to measure the methane content in the coalbed methane. After the measurement is completed, under the action of the cylinder 61, the bottom plate 63 drives the filter cylinder 64 to move upward, so that the bottom plate 63 seals the bottom end of the cylinder body 43 to prevent foreign objects from entering the inside of the cylinder body 43.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
