[0026] Embodiment 1, see Figures 1 - 8 , this embodiment provides a natural gas production well pressure boosting and production increasing device, including: a natural gas pipeline 1; an electric telescopic rod 5, which is assembled inside the natural gas pipeline 1; a connecting plate 6, which is assembled at the output end of the electric telescopic rod 5; an air pump 7, which is assembled inside the natural gas pipeline 1; an exhaust pipe 8, which is assembled on the side of the air pump 7; a suction pipe 9, which is assembled on the side of the air pump 7; a natural gas collection pipe 10, which is assembled on the top of the air pump 7; A first sleeve 21 is slidably connected to the side of the natural gas pipeline 1. A second sleeve 22 is slidably connected to the inner wall of the first sleeve 21. A spring is assembled on the right side of the second sleeve 22. A vertical plate 23 is assembled on the side of the first sleeve 21. A first rotating rod 24 is rotatably connected to the front of the vertical plate 23 through a bearing. A dispersion claw 25 is fixedly sleeved on the outer wall of the first rotating rod 24. A first baffle 26 is fixedly connected to the outer wall of the first sleeve 21. A moving ring 211 is slidably connected inside the first sleeve 21. An extrusion rod 212 is fixedly connected to the side of the moving ring 211. A transmission component for driving the second sleeve 22 and the extrusion rod 212 is assembled inside the natural gas pipeline 1. An electric telescopic rod 5 is assembled inside the natural gas pipeline 1 to drive the connecting plate 6 to move. Cooperating with an air pump 7 assembled inside the natural gas pipeline 1, natural gas collection and pressurization are achieved through an exhaust pipe 8 and an air suction pipe 9. A natural gas collection pipe 10 is assembled on the top of the air pump 7 for discharging the collected natural gas. Components such as the first sleeve 21, the second sleeve 22, the spring, the vertical plate 23, the first rotating rod 24, and the dispersion claw 25 slidably connected to the side of the natural gas pipeline 1 constitute a dispersion mechanism. When the electric telescopic rod 5 inside the natural gas pipeline 1 drives the connecting plate 6 to move, relative movement between the second sleeve 22 and the extrusion rod 212 is generated through the transmission component, squeezing the dispersion claw 25, and making it disperse the surrounding coal seam under the rotation of the first rotating rod 24, expanding the coal seam cracks, increasing the natural gas seepage channels, and improving the output. A limiting plate 27 for preventing the first sleeve 21 from rotating when moving is fixedly connected to the outer wall of the first sleeve 21. A second baffle 213 is fixedly connected to the outer wall of the first sleeve 21. A torsion spring is assembled on the outer wall of the first rotating rod 24. The limiting plate 27 fixedly connected to the outer wall of the first sleeve 21 prevents the first sleeve 21 from rotating when moving. The torsion spring assembled on the outer wall of the first rotating rod 24 enables the dispersion claw 25 to reset after completing the dispersion action, preparing for the next dispersion action. The transmission component includes a connecting block 210. A chute is opened at the bottom of the inner wall of the second sleeve 22. The connecting block 210 is slidably connected to the inner wall of the chute. A limiting ring 28 is fixedly connected to the inner wall of the first sleeve 21. A connecting rod 29 is fixedly connected to the side of the connecting block 210. The connecting rod 29 extends to the right side through the limiting ring 28 in an active manner. The extended end of the connecting rod 29 is fixedly connected to the side of the moving ring 211. The transmission component slides the connecting block 210 in the chute of the second sleeve 22. The connecting rod 29 extends through the limiting ring 28 in an active manner and is connected to the moving ring 211, converting the sliding of the second sleeve 22 into the movement of the moving ring 211, and then driving the extrusion rod 212 to apply an extrusion force to the dispersion claw 25, realizing the opening and closing action of the dispersion claw 25 and ensuring its effective dispersion of the coal seam. The side of the extrusion rod 212 is formed into a hemisphere for extruding the bottom of the dispersion claw 25. The pre-tightening force and deformation resistance of the spring are significant. The hemispherical structure on the side of the extrusion rod 212 facilitates extruding the bottom of the dispersion claw 25, enabling the dispersion claw 25 to open smoothly. Moreover, the pre-tightening force and deformation resistance of the spring are significant, ensuring that the dispersion claw 25 has sufficient force and stability during the extrusion and reset processes.

[0027] When the above-mentioned device is used, the natural gas pipeline 1 is inserted into the coal seam, and the electric telescopic rod 5 is started. The electric telescopic rod 5 drives the connecting plate 6 to move to the right, and the connecting plate 6 pushes the second sleeve 22 and the first sleeve 21 to move to the right. Due to the large elastic coefficient of the spring, the second sleeve 22 will not slide into the first sleeve 21 at this time. When the first sleeve 21 slides to the right, the limiting plate 27 can prevent the first sleeve 21 from rotating when moving. When the first sleeve 21 continues to move, it contacts the inner wall of the natural gas pipeline 1 through the first baffle 26, so that the first sleeve 21 can no longer move, and the connecting plate 6 can push the second sleeve 22 and the first sleeve 21 to move to the right. When the connecting plate 6 continues to push, the second sleeve 22 will slide to the right, the spring will be squeezed, the second sleeve 22 will drive the connecting block 210 to move to the right, the connecting block 210 will drive the connecting rod 29 to move to the right, the connecting rod 29 will drive the moving ring 211 to move to the right, the moving ring 211 will drive the extrusion rod 212 to move to the right, the extrusion rod 212 will move to the right to squeeze the dispersion claw 25, the dispersion claw 25 will open, the cracks in the coal seam will be propped open, the air pump 7 will be started, the air pump 7 will pass through the opened cracks through the exhaust pipe 8, the refluxed coal gas will be absorbed through the suction pipe 9, and discharged through the natural gas collection pipe 10.

The pushing device 3 includes a receiving groove 31, which is opened at the top of the dispersion claw 25. The inner wall of the receiving groove 31 is fixedly connected with a first hydraulic chamber 32, and the top of the first hydraulic chamber 32 is fixedly connected with a second hydraulic chamber 35, and the two are connected.

The second hydraulic chamber 35 has a second hydraulic rod 36 connected to it by a piston sliding at one end, and the second hydraulic rod 36 is fixedly connected to the top of the second baffle 213.

[0029] When the above-mentioned device is in specific use, when the dispersing claws 25 open, they drive the second hydraulic chamber 35 and the first hydraulic chamber 32 to move to the left. The second hydraulic rod 36 enters the interior of the second hydraulic chamber 35, increasing the pressure inside the second hydraulic chamber 35 and the first hydraulic chamber 32, driving the first hydraulic rod 33 to move forward. The first hydraulic rod 33 drives the push plate 34 to move forward, further enlarging the cracks in the coal seam.
