The walking wheels 3 of the walking assembly are installed at the four corners of the bottom plate 1, and a foot brake is provided on it. The walking wheels 3 can be braked when in use. A push handle 4 is welded on the bottom plate 1 to facilitate push-pull operations. It is a relatively mature technology and will not be described in detail here.

[0024] See also Figure 1-Figure 5In order to facilitate the connection between the gas tank 9 and the main body 2 of the dispersing device, to facilitate the extraction of the residual natural gas in the pipeline into the gas tank 9, and to facilitate the subsequent removal operation, the bottom plate 1 is symmetrically provided with a sliding groove 23 of a moving component. The sliding groove 23 is provided with a moving block 16 through an electric push rod 22, which can slide back and forth in the sliding groove 23. The top of the moving block 16 can be fixedly connected to the moving seat 8 by a screw, and the moving seat 8 is fastened to the gas tank 9 by a fastening mechanism to ensure firmness during use and convenient for subsequent use. Continue to remove and replace the operation, and in order to facilitate the plug-in and ensure the sealing, the end of the connecting pipe 13 is welded with a plug-in ring 14 of the plug-in mechanism, and the corresponding end of the exhaust pipe 12 is provided with a plug-in groove 10 that is plugged in and adapted to the plug-in ring 14, wherein two groups of sealing rings 11 are embedded in the inner wall of the plug-in groove 10, and the outer peripheral side of the plug-in ring 14 is provided with a sealing groove 15 that is interference fit with the sealing ring 11, the number of which can be one or three groups, or other numbers, to ensure the sealing effect during plug-in and facilitate the subsequent separation operation.

[0025] See also Figure 1-Figure 5 In order to facilitate the placement and fixation of the gas tank 9 and to facilitate subsequent removal and replacement operations, two sets of vertical plates 17 of the fastening mechanism are symmetrically welded on the movable seat 8. The middle part of the vertical plate 17 is engaged with an adjusting screw 20 through a thread, and the end of the adjusting screw 20 close to each other can be rotatably connected to the card seat 18 through a bearing, and the other end is welded with a knob, which can be conveniently rotated and adjusted. In order to ensure the stability of movement, the side walls of the card seat 18 away from each other are symmetrically welded with limiting slide bars 21, and the limiting slide bar 21 is slidably connected to the vertical plate 17. In order to better position and fix the gas tank 9, the inner arc surface of the card seat 18 and the movable seat 8 are bonded with anti-slip pads 19 to increase the friction when in contact with the gas tank 9.

[0026] Working principle: When the utility model is in use, when placing and fixing the gas tank 9, it is placed in the movable seat 8 and initially positioned and fixed under the action of the anti-skid pad 19, and then the adjusting screw 20 is rotated forward, in conjunction with the limiting slide bar 21, the two seats 18 can be brought close to each other, and then the gas tank 9 can be fixed and fastened in conjunction with the anti-skid pad 19, and then when it is connected to the exhaust pipe 12 of the dispersing device body 2, the electric push rod 22 is extended, and the movable block 16 slides in the slide groove 23, and then the plug-in ring 14 at the end of the connecting pipe 13 is inserted into the plug-in groove 10, and the sealing ring 11 and the sealing groove 15 are sealed and connected, and then the push handle 4 can be pushed, Under the action of the walking wheel 3, it moves to the designated work place. The natural gas in the pipeline can be extracted by the dispersing device body 2 in conjunction with the connector 5, and then pumped into the gas storage tank 9 through the exhaust pipe 12 and the connecting pipe 13 for storage. After the collection is completed, the valve on the connecting pipe 13 can be closed, and then the electric push rod 22 is retracted to move the moving block 16 to reset, and then the connecting pipe 13 is separated from the exhaust pipe 12. By rotating the adjusting screw 20 in the opposite direction, the two holders 18 are moved away from each other, and the positioning and fixation of the gas storage tank 9 can be lost. Then, the collected gas storage tank 9 can be removed for subsequent recycling and use. At the same time, the above operation can be repeated to assemble a new empty gas storage tank 9 for the next use.
