[0002] Gas is also known as natural gas. Due to the particularity of the extraction process of coal mine gas, the composition of different gas sources varies greatly. Some of these harmful components will pose a hidden danger to the safe operation of the coal mine gas transmission and distribution system. If sulfur oxides, hydrogen sulfide, etc. exceed the standard, they will cause corrosion to the coal mine gas transmission pipeline, and the fluctuation of methane concentration and the water content of gas will affect the measurement accuracy, transmission difference and the safe use of gas by users.

Therefore, the directional terms used are used to illustrate rather than limit the invention.

[0037] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0038] Example: A mobile natural gas detection device, see attached Figure 1 -Attached Figure 8 , including a box body 1, universal wheels 12, a lifting device 2 and a detection mechanism. One side of the box body 1 is set as a box door, and the bottom of the box body 1 is set as a lifting plate 11. The lifting plate 11 can move up and down and slide into the box body 1; there are multiple universal wheels 12 and they are set at the bottom of the lifting plate 11; there are two lifting devices 2 and they are respectively located on both sides of the box body 1. The lifting devices 2 are used to drive the lifting plate 11 to move up and down; the detection mechanism is set in the box body 1 and is used to detect natural gas.

[0039] When installing the detection equipment next to the conveying pipeline, large transport vehicles cannot transport the detection equipment directly to the location. In the traditional installation process, the detection equipment needs to be transported to the conveying pipeline by manual transportation. In this embodiment, the lifting plate 11 is lowered to make the universal wheel 12 contact with the ground, thereby pushing the box 1 to move, making the installation of the detection equipment time-saving, labor-saving, convenient and quick; after the box 1 is in place, the lifting plate 11 is moved upward to make the universal wheel 12 completely retracted into the box 1, so that the bottom of the box 1 touches the ground, thereby preventing the box 1 from moving when the detection equipment is running.

[0040] Specifically, the bottom of both sides of the box body 1 is provided with a clearance groove 15, and two connecting plates are fixedly connected to both sides of the lifting plate 11. The two connecting plates extend out of the box body 1 from the two clearance grooves 15 respectively. The lifting device 2 includes a support shell 21 and a rotating rod 22. The support shell 21 is fixedly connected to the outside of the box body 1. The two connecting plates are respectively located in the two support shells 21 of the two lifting devices 2, and the connecting plates slide up and down in the support shells 21. The axis of the rotating rod 22 is vertically arranged, and the rotating rod 22 is rotatably connected to the support shell 21. The rotating rod 22 vertically passes through the connecting plate and is threadedly connected to the connecting plate. The part of the connecting plate extending out of the box body 1 is connected to the inner wall of the support shell 21. The support shell 21 is open on the side close to the clearance groove 15.

[0041] By rotating the rotating rod 22 , the connecting plate can be driven to move up and down, thereby driving the lifting plate 11 to move up and down.

[0042] Specifically, this embodiment also includes a leveling mechanism 3, and there are four leveling mechanisms 3. Two leveling mechanisms 3 are provided on each side of the lifting device 2 of the box body 1, and the two leveling mechanisms 3 located on the same side of the box body 1 are respectively located on both sides of the support shell 21; the leveling mechanism 3 includes an adjusting rod 32, a support plate 31, a connecting seat 33 and a rotating ball 34, the adjusting rod 32 is vertically arranged and can slide up and down outside the box body 1; the support plate 31 is horizontally arranged and located below the adjusting rod 32; the top of the support plate 31 is fixedly connected to the connecting seat 33; the bottom of the adjusting rod 32 is fixedly connected to the rotating ball 34, the rotating ball 34 is embedded in the connecting seat 33 and can rotate around its own ball center in the connecting seat 33, and the height of the ball center of the rotating ball 34 is lower than the height of the top of the connecting seat 33.

[0043] Since the ground where the box 1 is installed is often uneven, the box 1 is prone to being unable to maintain a level surface. By vertically moving the four adjustment rods 32, the heights of the four corners of the box 1 can be adjusted individually, so that the box 1 can be adjusted to a level surface on an uneven ground. By setting the rotating ball 34, it can be ensured that the support plate 31 is in contact with the ground even when the ground is uneven, thereby improving the stability of the support for the box 1.

[0044] Specifically, the leveling mechanism 3 also includes a horizontal plate 35, to which an adjustment sleeve 36 is rotatably connected. The axis of the adjustment sleeve 36 is vertical and rotatably connected to the horizontal plate 35. The adjustment rod 32 vertically passes through the adjustment sleeve 36 and is threadedly connected to the adjustment sleeve 36. Rotation of the adjustment sleeve 36 drives the adjustment rod 32 to move vertically, thereby achieving leveling of the box 1. Specifically, an auxiliary sleeve 37 is fixedly connected to the outside of the adjustment sleeve 36. The cross-section of the auxiliary sleeve 37 is a regular hexagon, which facilitates the rotation of the adjustment sleeve 36.

[0045] Specifically, the leveling mechanism 3 also includes a guide plate 38, which is provided with a guide hole 381 extending vertically therethrough. The adjustment rod 32 extends vertically through the guide hole 381. Two vertical positioning slots 321 are provided on either side of the adjustment rod 32. Two positioning blocks 382 are fixedly attached to the walls of the guide hole 381 and are respectively embedded in the two positioning slots 321. The positioning slots 321 and positioning blocks 382 ensure that the adjustment rod 32 does not rotate with the adjustment sleeve 36 during rotation, thereby achieving vertical movement of the adjustment rod 32.

[0046] Specifically, the detection mechanism includes a detection pipeline and a connecting pipe 13, the detection pipeline is connected to a methane sensor, and / or a dew point sensor, and / or an oxygen sensor, and / or a micro-oxygen sensor, and / or a total sulfur analyzer; the connecting pipe 13 is provided with two and is fixedly connected to both sides of the box body 1, and the two connecting pipes 13 are respectively connected to the air inlet end and the air outlet end of the detection pipeline, and the connecting pipe 13 is connected to the natural gas transmission pipeline through a pipeline.

[0047] This embodiment also includes a sealing plug 4, which is configured as an elastic sealing plug 4. The sealing plug 4 can be inserted into the connecting pipe 13 and cooperate with the connecting pipe 13; the connecting pipe 13 is fixedly connected to a flange 131 at one end away from the box body 1, and a connecting plate 41 is fixedly connected to the sealing plug 4. The connecting plate 41 and the flange 131 can be connected together by bolts and nuts.

[0048] By setting the sealing plug 4, when the detection equipment is transported or not in use, the two connecting pipes 13 can be sealed by the sealing plug 4, thereby achieving sealing of the detection pipeline and preventing external dust and impurities from entering the detection pipeline.

[0049] Specifically, this embodiment further includes two temporary storage tubes 14, each of which is fixedly connected to both sides of the housing 1. The sealing plug 4 can be inserted into and engaged with the temporary storage tubes 14. Due to the provision of the temporary storage tubes 14, when the connecting pipe 13 is connected to the natural gas transmission pipeline via a pipeline, the sealing plug 4 on the connecting pipe 13 can be removed and inserted into the temporary storage tube 14 for storage.
