[0035] A circular sliding ring 7 is fixed to the bottom of the vertical sliding pipe 2, and a vertical groove adapted to the circular sliding ring 7 is opened inside the vertical geothermal well pipe 1. The vertical sliding pipe 2 and the vertical geothermal well pipe 1 are slidingly connected through the circular sliding ring 7 and the vertical groove, and a circular buffer ring 9 is also arranged on the top of the circular sliding ring 7. Through the arrangement of the vertical groove and the circular sliding ring 7, the circular sliding ring 7 can slide inside the vertical geothermal well pipe 1. The arrangement of the circular buffer ring 9 can buffer the circular sliding ring 7 when it is connected to the top of the vertical geothermal well pipe 1, so as to prevent the vertical sliding pipe 2 from moving excessively and causing damage to the circular sliding ring 7.

[0036] The vertical buffer mechanism includes a first hydraulic cylinder 14, a plurality of first hydraulic cylinders 14 are evenly arranged at the bottom of the circular fixing ring 5, a first piston rod 15 is slidably connected to the inside of the bottom end of the first hydraulic cylinder 14, a circular mounting block 16 is fixed to the bottom of the first piston rod 15, the bottom of the circular mounting block 16 is fixedly connected to the vertical geothermal well pipeline 1, a vertical circular slider 13 is slidably connected to the outside of the first hydraulic cylinder 14, and a first rigid spring 17 is arranged between the vertical circular slider 13 and the circular mounting block 16 and located on the outside of the first hydraulic cylinder 14;

[0037] A lifting assembly for lifting the vertical circular slider 13 is also provided between the circular fixing ring 5 and the vertical geothermal well pipe 1;

[0038] The lifting assembly includes a vertical threaded rod 10, the vertical threaded rod 10 is arranged inside the circular fixing ring 5, a vertical hand wheel 12 is fixed to the top of the vertical threaded rod 10, the outer side of the vertical threaded rod 10 passes through the inside of the circular lifting ring 6 and is threadedly connected to the circular lifting ring 6, a vertical circular slider 13 is located inside the circular lifting ring 6 and is fixedly connected to the circular lifting ring 6, and a vertical light rod 11 is also fixed at the bottom of the circular fixing ring 5 and at one end of the vertical threaded rod 10, and the vertical light rod 11 passes through the inside of the circular lifting ring 6 and is slidably connected to the circular lifting ring 6;

[0039] A plurality of vertical slide bars are evenly distributed and fixed on the outside of the first hydraulic cylinder 14, and a rectangular groove adapted to the vertical slide bar is provided inside the vertical circular slide bar 13. The first hydraulic cylinder 14 and the vertical circular slide bar 13 are slidably connected by the vertical slide bar and the rectangular groove, so that the vertical circular slide bar 13 can slide on the outside of the first hydraulic cylinder 14.

[0042] Example 2

[0043] like Figure 6~Figure 8 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes an adjustment mechanism;

[0044] In this embodiment, the adjustment mechanism includes a transverse threaded rod 21, the interior of the rectangular equipment box 4 is provided with the transverse threaded rod 21, one end of the transverse threaded rod 21 is fixed with a transverse hand wheel 22, the outer side of the transverse threaded rod 21 is threadedly connected with a rectangular sliding box 20, and the bottom of the rectangular sliding box 20 is provided with an oblique rotating plate 19, the bottom of the oblique rotating plate 19 is rotatably connected to the oblique buffer plate 8 through a pin shaft, and the top of the oblique buffer plate 8 is rotatably connected to the rectangular guide pipe 3 through a pin shaft;

[0045] A transverse polished rod 23 is fixed on both sides of the transverse threaded rod 21. The transverse polished rod 23 is located inside the rectangular device box 4 and is fixedly connected to the rectangular device box 4. The transverse polished rod 23 penetrates the interior of the rectangular sliding box 20 and is slidably connected to the vertical sliding pipe 2. Through the arrangement of the transverse polished rod 23, the rectangular sliding box 20 can slide on the outside of the transverse polished rod 23, thereby guiding the moving trajectory of the rectangular sliding box 20.

[0046] A trapezoidal stopper 18 is provided at the top and bottom of the rectangular guide pipe 3 and at one end of the oblique buffer plate 8. A buffer pad is provided at one end of the trapezoidal stopper 18. The buffer pad can effectively block the impact of the material and effectively prevent the damage of the trapezoidal stopper 18. The trapezoidal stopper 18 can reduce the water hammer efficiency of the material flow.

[0047] A transverse sliding block 24 is slidably connected inside the rectangular sliding box 20, and the bottom of the transverse sliding block 24 is rotatably connected to the oblique rotating plate 19 through a pin shaft. A second hydraulic cylinder 26 is arranged inside the rectangular sliding box 20, and a second piston rod 27 is arranged inside the second hydraulic cylinder 26. The second piston rod 27 is fixedly connected to the transverse sliding block 24, and a second rigid spring 28 is arranged between the transverse sliding block 24 and the rectangular sliding box 20 and on the outside of the second hydraulic cylinder 26;

[0048] A transverse limiting rod 25 is also fixed inside the rectangular sliding box 20. The transverse limiting rod 25 passes through the interior of the transverse sliding block 24 and is slidably connected to the transverse sliding block 24, so that the transverse sliding block 24 can slide outside the transverse limiting rod 25. When the transverse sliding block 24 slides outside the transverse limiting rod 25, the second piston rod 27 can slide inside the second hydraulic cylinder 26.

[0049] Here, the transverse hand wheel 22 is rotated, and the rotation of the transverse hand wheel 22 enables the transverse threaded rod 21 to rotate, and the rotation of the transverse threaded rod 21 enables the rectangular sliding box 20 to slide on the outside of the transverse light rod 23. The sliding of the rectangular sliding box 20 enables the oblique buffer plate 8 to rotate with the connection between the oblique buffer plate 8 and the rectangular diversion pipe 3 as the center of the circle through the transverse sliding block 24 and the oblique rotating plate 19, thereby adjusting the rotation amplitude of the oblique buffer plate 8. When the material enters the interior of the rectangular diversion pipe 3, the material can cause a water hammer effect on the oblique buffer plate 8, so that the oblique buffer plate 8 can rotate inside the rectangular diversion pipe 3, thereby causing the transverse sliding block 24 to slide on the outside of the transverse limit rod 25. Through the arrangement of the second hydraulic cylinder 26, the second piston rod 27 and the second rigid spring 28, the rotation amplitude of the oblique buffer plate 8 can be effectively reduced, and the flow rate of the material can be effectively slowed down to prevent the material flow rate from being too fast and causing excessive pressure inside the rectangular diversion pipe 3.

[0050] A specific application of the above two embodiments is that the vertical threaded rod 10 can be rotated by rotating the vertical hand wheel 12, and the rotation of the vertical threaded rod 10 enables the circular lifting ring 6 to slide vertically on the outside of the vertical bare rod 11. The sliding of the circular lifting ring 6 enables the vertical circular slider 13 to slide on the outside of the first hydraulic cylinder 14, and the distance between the vertical circular slider 13 and the circular mounting block 16 can be adjusted, so that the first piston rod 15 is deformed by force, and then the force state of the first piston rod 15 can be adjusted. When the pressure inside the vertical geothermal well pipeline 1 exceeds a certain threshold, the first hydraulic cylinder 14 can slide on the outside of the first piston rod 15, so that the vertical sliding pipeline 2 can move in a direction away from the vertical geothermal well pipeline 1, so that the circular sliding ring 7 can slide inside the vertical geothermal well pipeline 1, so that the material inside the vertical geothermal well pipeline 1 can enter the interior of the rectangular diversion pipeline 3, and the material inside the vertical geothermal well pipeline 1 can be diverted;

[0051] Rotate the transverse handwheel 22, and the rotation of the transverse handwheel 22 enables the transverse threaded rod 21 to rotate. The rotation of the transverse threaded rod 21 enables the rectangular sliding box 20 to slide on the outside of the transverse light rod 23. The sliding of the rectangular sliding box 20 enables the oblique buffer plate 8 to rotate with the connection between the oblique buffer plate 8 and the rectangular diversion pipe 3 as the center of the circle through the transverse sliding block 24 and the oblique rotating plate 19, thereby adjusting the rotation amplitude of the oblique buffer plate 8. When the material enters the interior of the rectangular diversion pipe 3, the material can cause a water hammer effect on the oblique buffer plate 8, so that the oblique buffer plate 8 can rotate inside the rectangular diversion pipe 3, thereby causing the transverse sliding block 24 to slide on the outside of the transverse limit rod 25. Through the arrangement of the second hydraulic cylinder 26, the second piston rod 27 and the second rigid spring 28, the rotation amplitude of the oblique buffer plate 8 can be effectively reduced, and the flow rate of the material can be effectively slowed down to prevent the material flow rate from being too fast and causing excessive pressure inside the rectangular diversion pipe 3.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
