Description

Technical Field

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

[0002] Medium-deep geothermal refers to geothermal resources at a deeper level underground, usually referring to thermal energy located hundreds to thousands of meters underground. It is different from shallow geothermal (such as geothermal water and hot springs), which mainly relies on thermal conduction of underground rocks to obtain energy. The heat source of medium-deep geothermal is located deep underground, usually between 300 meters and 5,000 meters deep. The geothermal resources in this range have higher temperatures and are suitable for large-scale geothermal power generation and heating systems. The development of medium-deep geothermal is more complicated than shallow geothermal. It requires drilling technology to exploit underground thermal energy and transfer heat to the ground through a heat exchange system. Medium-deep geothermal resources are relatively durable, especially under suitable geological conditions. They can provide thermal energy stably for a long time and will not be exhausted like fossil fuels. The medium-deep geothermal cascade energy supply device is a system that utilizes deep underground geothermal resources, mainly used for efficient extraction and utilization of geothermal energy. This device usually uses a graded extraction method to obtain heat energy from geothermal resources, and after processes such as heat exchange, the heat is used for heating, power generation or other industrial purposes.

[0003] Existing mid- 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

[0036] 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 driving 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.

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 blockage of the limit rod 43. Then the electromagnet 82 absorbs the second locking frame 48. Driven by the first hydraulic rod 65, the clamping mechanism 7 and the unlocking mechanism 8 drive the pipeline 9 and the second locking frame 48 to move to a position close to the lifting track 5, so that they rise under the drive mechanism 6 to replace the pipeline 9. Afterwards, the driving mechanism 6 moves to the replacement position with the new pipe 9, and is pushed by the first hydraulic rod 65 to make the pipe 9 and the second locking frame 48 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 ring 10 between the pipes 9 is squeezed and sealed against each other, and the replacement of the pipe 9 is completed. 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 bar 64 to retract the clamp mechanism 7 and the unlocking mechanism 8.
