Description

Technical Field

[0001] The present invention belongs to the technical field of geothermal mining, and in particular relates to a medium-deep geothermal cascade energy supply device. Background Art

[0002] Deep geothermal refers to geothermal resources located deeper underground, typically hundreds to thousands of meters below the surface. Unlike shallow geothermal resources (such as geothermal water and hot springs), deep geothermal energy primarily relies on heat conduction from underground rocks. The heat source of deep geothermal energy lies deep underground, typically between 300 and 5,000 meters. Geothermal resources in this range have higher temperatures, making them suitable for large-scale geothermal power generation and heating systems. The development of deep geothermal energy is more complex than that of shallow geothermal resources, requiring drilling to extract the underground heat and transferring it to the surface through a heat exchange system. Deep geothermal resources are relatively durable, especially under suitable geological conditions, and can provide stable heat for long periods of time, unlike fossil fuels that deplete. A deep geothermal cascade power supply system is a system that utilizes deep geothermal resources, primarily for the efficient extraction and utilization of geothermal energy. This system typically uses a staged extraction method to extract heat from the geothermal resource and, through heat exchange and other processes, uses the heat for heating, power generation, or other industrial purposes.

[0003] Existing medium- and deep-layer geothermal cascade energy supply devices often transfer heat energy through pipes. After long-term use, the pipes are inevitably damaged. However, since the pipes are located deep underground, it is difficult for workers to go down to the damaged areas to carry out replacement and maintenance work. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a medium-deep geothermal cascade energy supply device.

[0020] Through the above technical solution, the second hydraulic rod pushes the rocker arm to rotate, and the rocker arm drives the fixed clamp to clamp the pipe.

[0045] A pipe 9 is fixedly connected inside the fixing mechanism 3, and a driving mechanism 6 is slidably connected to the lifting track 5. The driving mechanism 6 includes a driving box 61 slidably connected to the slide rail 52. A first motor 62 is fixedly connected inside the driving box 61. The output end of the first motor 62 is fixedly connected to the second gear 63. The second gear 63 and the rack 53 are engaged with each other. The end of the driving box 61 away from the third fixed plate 51 is fixedly connected to a pair of sliding rods 64. The end of the driving box 61 close to the sliding rod 64 is fixedly connected to the first hydraulic rod 65. The ends of the pair of sliding rods 64 away from the driving box 61 are fixedly connected to the limiting block 66. The first motor 62 drives the second gear 63 to rotate, and the second gear 63 cooperates with the rack 53 to drive the driving box 61 to descend along the slide rail 52 to the position of the damaged pipe 9.

[0046] Both ends of the pipe 9 are fixedly connected with a sealing ring 10. When the first locking frame 41 and the second locking frame 48 are pressed together, the sealing rings 10 between the pipes 9 are squeezed and sealed.

[0047] like Figures 4-10As shown, a locking mechanism 4 is fixedly connected to the second fixing plate 2, and the locking mechanism 4 includes a first locking frame 41 fixed to the second fixing plate 2, and a second locking frame 48 is provided at one end of the first locking frame 41 away from the second fixing plate 2, and both ends of the first locking frame 41 are slidably connected with a fixing bolt 44, and both ends of the second locking frame 48 are rotatably connected with a rotating sleeve 49, and the rotating sleeve 49 is fixedly connected to the outside of the rotating sleeve 49. The first gear 410 drives the rotating sleeve 49 to rotate, and the rotating sleeve 49 is threadedly engaged with the fixing bolt 44, so that the rotating sleeve 49 is removed from the fixing bolt 44. At this time, the fixing bolt 44 is driven by the first spring 47 to move away from the rotating sleeve 49, and then stops under the obstruction of the limit rod 43, and then the electromagnet 82 adsorbs the second locking frame 48 to remove the second locking frame 48.

[0048] A strip hole 45 is opened on the fixing bolt 44, and both ends of the first locking frame 41 are fixedly connected to the first connecting block 42. The fixing bolt 44 passes through the first connecting block 42 for sliding connection. A limiting rod 43 is fixedly connected to the first connecting block 42. The limiting rod 43 passes through the sliding connection strip hole 45. The end of the fixing bolt 44 away from the second locking frame 48 is fixedly connected to a baffle 46. The baffle 46 is fixedly connected to a first spring 47. The end of the first spring 47 away from the baffle 46 is fixedly connected to the first connecting block 42. The rotating sleeve 49 is fixedly connected to the first connecting block 42. A limiting ring 411, the inner sides of the first locking frame 41 and the second locking frame 48 are inclined, the rotating sleeve 49 and the fixing bolt 44 are threadedly matched with each other, the first gear 410 drives the rotating sleeve 49 to rotate, and the rotating sleeve 49 cooperates with the fixing bolt 44 to drive the second locking frame 48 closer to the first locking frame 41. Through the use of the limiting rod 43, on the one hand, the rotation of the fixing bolt 44 is blocked, and on the other hand, the fixing bolt 44 is prevented from falling off. At the same time, through the use of the first spring 47, the second locking frame 48 and the first locking frame 41 can be fixed more tightly.

[0049] like Figure 11 As shown, the driving mechanism 6 is fixedly connected to a clamping mechanism 7, and the clamping mechanism 7 includes a fixed base 71 fixedly connected to the first hydraulic rod 65, and the upper and lower ends of the fixed base 71 are fixedly connected to a fixed frame 72, and the two ends of the fixed frame 72 are rotatably connected to a rocker arm 73, and the rocker arm 73 is rotatably connected to the end between the end close to the fixed frame 72, and the rocker arm 73 is rotatably connected to the end away from the second hydraulic rod 74. The fixed clamping jaw 75 is rotatably connected to the inner side of the fixed clamping jaw 75. A pair of pads 76 are fixedly connected to the inner side of the fixed clamping jaw 75, and the pads 76 are provided with anti-slip grooves. The sliding rod 64 passes through and is slidably connected to the fixed base 71, and the second hydraulic rod 74 pushes the rocker arm 73 to rotate, and the rocker arm 73 drives the fixed clamping jaw 75 to clamp the pipe 9.

[0050] like Figure 12-15As shown, the upper and lower ends of the clamping mechanism 7 are fixedly connected to the unlocking mechanism 8, and the unlocking mechanism 8 includes a shell 81 fixedly connected to the clamping mechanism 7, an electromagnet 82 is fixedly connected to the shell 81, and both ends of the electromagnet 82 are fixedly connected to a fixed arm 83, and the end of the fixed arm 83 away from the electromagnet 82 is fixedly connected to the shell 84, and a second slider 814 is slidably connected in the shell 84, and a moving shaft 815 is rotatably connected in the second slider 814, and a third gear 816 is fixedly connected to the moving shaft 815, and the first gear 410 and the third gear 816 are engaged with each other. The second spring 88 pushes the first slider 89 to move in the slideway 87, and the first slider 89 drives the tensioning roller 811 to move, so that the belt 812 is always kept in a tensioned state to prevent the belt 812 from falling off.

[0051] A second motor 85 is fixedly connected to the housing 81, and the output end of the second motor 85 is fixedly connected to the driving roller 86. A slideway 87 is fixedly connected to the housing 81, and a first slider 89 is slidably connected to the slideway 87. The first slider 89 is fixedly connected to the second spring 88. The first slider 89 is fixedly connected to a rotating shaft 810. The end of the rotating shaft 810 away from the first slider 89 is rotatably connected to the tensioning roller 811. The end of the movable shaft 815 away from the third gear 816 is fixedly connected to the driven roller 817. The driving roller 86, the driven roller 817 and the tensioning roller 811 are all covered with a belt 8 12. One end of the second slider 814 is fixedly connected to the third spring 813. The movable shaft 815 passes through the sliding connection shell 84. The rotating shaft 810 passes through the sliding connection shell 81. The second motor 85 drives the active roller 86 to rotate. The active roller 86 drives the driven roller 817 to rotate through the belt 812. The driven roller 817 drives the third gear 816 to rotate through the movable shaft 815. The third gear 816 drives the first gear 410 to rotate. The first gear 410 drives the rotating sleeve 49 to rotate. The rotating sleeve 49 is threadedly engaged with the fixing bolt 44, so that the rotating sleeve 49 is removed from the fixing bolt 44.

[0052] The working principle of this embodiment is as follows: the first motor 62 drives the second gear 63 to rotate, and the second gear 63 cooperates with the rack 53 to drive the drive box 61 to descend along the slide rail 52 to the position of the damaged pipe 9. During the descent, the second slider 814 is pushed to move by the third spring 813, and the second slider 814 drives the moving shaft 815 to move, and the moving shaft 815 drives the third gear 816 to move, so that the third gear 816 can be ensured to move to a position meshing with the first gear 410 when descending, and will not interfere with other first gears 410. When the moving shaft 815 moves, the second spring 88 pushes the first slider 89 to move in the slideway 87, and the first slider 89 drives the tensioning roller 811 to move, so that the belt 812 is always kept in a tensioned state to prevent the belt 812 from falling off;

[0053] When the driving mechanism 6 moves to the desired position, the second hydraulic rod 74 pushes the rocker arm 73 to rotate, and the rocker arm 73 drives the fixed clamping claw 75 to clamp the pipe 9. At this time, the third gear 816 is engaged with the first gear 410, and the second motor 85 drives the active roller 86 to rotate. The active roller 86 drives the driven roller 817 to rotate through the belt 812. The driven roller 817 drives the third gear 816 to rotate through the movable shaft 815. The third gear 816 drives the first gear 410 to rotate, and the first gear 410 drives the rotating sleeve 49 rotates, and the rotating sleeve 49 is threadedly engaged with the fixing bolt 44, so that the rotating sleeve 49 is removed from the fixing bolt 44. At this time, the fixing bolt 44 is driven by the first spring 47 to move away from the rotating sleeve 49, and then stops under the obstruction of the limit rod 43. Then the electromagnet 82 attracts the second locking frame 48. Driven by the first hydraulic rod 65, the clamping mechanism 7 and the unlocking mechanism 8 drive the pipe 9 and the second locking frame 48 to a position close to the lifting track 5, so that the pipe 9 is lifted up under the drive mechanism 6, and the pipe 9 is replaced;

[0054] Afterwards, the driving mechanism 6 moves the new pipe 9 to the replacement position, and is pushed by the first hydraulic rod 65, so that the pipe 9 and the second locking frame 48 are close to the fixing mechanism 3, and the first clamp 33 and the second clamp 34 are squeezed apart by the pipe 9. Under the action of the torsion spring 35, the first clamp 33 and the second clamp 34 clamp the pipe 9 and fix it. Then, the second motor 85 drives the third gear 816 to rotate, so that the third gear 816 drives the first gear 410 to rotate, and the first gear 410 drives the rotating sleeve 49 to rotate. The rotating sleeve 49 cooperates with the fixing bolt 44 to drive the second locking frame 48 to move closer to the first locking frame 41. Under the pressure of the first locking frame 41 and the second locking frame 48, the sealing rings 10 between the pipes 9 are squeezed and sealed against each other, completing the replacement of the pipe 9. Then, the second hydraulic rod 74 is shortened to loosen the fixed clamp 75, and the first hydraulic rod 65 is shortened to move the fixed base 71 along the slide rod 64, retracting the clamping mechanism 7 and the unlocking mechanism 8.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
