Description

Technical Field

[0001] This invention belongs to the field of geothermal well water extraction technology, specifically relating to a medium-deep geothermal well insulation and water extraction structure. Background Technology

[0002] Geothermal wells refer to the methods and devices used to generate electricity from geothermal energy or hot spring water with a temperature greater than 30°C at a depth of about 3,500 meters. Geothermal energy is divided into three categories: high temperature, medium temperature, and low temperature. Geothermal energy exists in the form of steam at temperatures above 150°C. Geothermal energy exists in the form of a mixture of water and steam at temperatures between 90°C and 150°C. Geothermal energy exists in the form of warm water, warm hot water, or hot water at temperatures above 25°C and below 90°C. Geothermal energy exists in the form of warm water, warm hot water, or hot water.

[0003] Medium-deep geothermal wells are mainly designed to facilitate the extraction of hot spring water from underground for use. Typical installations consist of a fixed support structure that vertically drives the water intake pipe into the ground to extract the hot spring water. During this process, the water intake pipe needs to be kept relatively vertical. Current installations cannot maintain this verticality, requiring construction workers to constantly adjust the pipe's position, thus slowing down the work process. Summary of the Invention

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0015] Please see Figures 1-6The present invention provides the following technical solution: a medium-deep geothermal well insulation and water intake structure, including a base plate 15, an adjustment mechanism, an auxiliary mechanism, and an insulation mechanism respectively arranged on the top of the base plate 15, and a limit mechanism arranged on the top of the base plate 15. The adjustment mechanism includes a fixed base 1, a working box 4, a motor 6, sliding springs 7, a threaded rod 5, and a sliding plate 2. The fixed base 1 is fixedly connected to one side of the top of the base plate 15, the working box 4 is fixedly connected to the top of the fixed base 1, the motor 6 is fixedly connected to the top of the working box 4, the drive end of the motor 6 is fixedly connected to the threaded rod 5, the threaded rod 5 passes through the top of the working box 4, and its bottom end is fixedly connected to the bottom of the inner wall of the working box 4. Two sliding springs 7 are sleeved on the outside of the threaded rod 5. The outer sides of the sliding springs 7 are fixedly connected to both ends of the inner wall of the working box 4, and the inner sides of the two sliding springs 7 are fixedly connected to both ends of the sliding plate 2. The sliding plate 2 has a threaded rod 5 passing through the middle. In this embodiment, before use, the base plate 15 is placed on the ground surface and made to fit tightly against the ground surface. Multiple counterweights are placed on the surface of the base plate 15 to keep it relatively stable. During use, the operator only needs to drive the motor 6. By adjusting the motor 6, the threaded rod 5 can be rotated, and the sliding plate 2 can slide up and down inside the working box 4. When the sliding plate 2 reaches a certain position, the motor 6 stops driving. Then, under the action of the sliding springs 7, the position of the sliding plate 2 can be kept relatively stable.

[0016] Specifically, the auxiliary mechanism includes a sliding plate 2, a limiting block 3, a water intake pipe 8, a fixed limiting plate 22, a rotating limiting plate 9, a first fixed plate 10, a fixing bolt 11, a rotating plate 12, a second fixed plate 20, a ball 23, a limiting groove 26, and a rotating shaft 21. The fixed limiting plate 22 and the rotating limiting plate 9 are respectively installed on the top side of the sliding plate 2 away from the working box 4. A rotating shaft 21 is installed at one end of the sliding plate 2. The two ends of the rotating shaft 21 are respectively fixedly connected to the sliding plate 2 and the fixed limiting plate 22, as well as the rotating plate 12 and the rotating limiting plate 9. Limiting blocks 3 are fixedly connected to both ends of shaft 21. A first fixing plate 10 is fixedly connected to one end of rotating plate 12. Two fixing bolts 11 are provided on the first fixing plate 10. The two fixing bolts 11 are screwed through the first fixing plate 10 and screwed onto sliding plate 2 and rotating plate 12, respectively. A second fixing plate 20 is fixedly connected to one end of rotating limiting plate 9. Two fixing bolts 11 are provided on the second fixing plate 20. The two fixing bolts 11 are screwed through the second fixing plate 20 and screwed onto fixed limiting plate 22 and rotating limiting plate, respectively. On plate 9, a circular through groove is formed on the inner side of the sliding plate 2 and the rotating plate 12. Multiple limiting grooves 26 are respectively provided on the circumference of the circular through groove. A ball 23 rotates inside the multiple limiting grooves 26. In this embodiment, the construction personnel need to vertically place the water intake pipe 8 against one end of the fixed limiting plate 22 and one end of the sliding plate 2. When the water intake pipe 8 is stably placed inside, the rotating plate 12 and the rotating limiting plate 9 are moved under the action of the rotating shaft 21, thereby causing the first fixed plate 10 to tightly fit against one end of the sliding plate 2, and simultaneously causing the second fixed plate 20 to fit against the fixed limiting plate 2. One end of plate 2 is tightly fitted together, thereby fixing the rotating plate 12 and the sliding plate 2 together by screwing in the fixing bolts 11. At the same time, the rotating limiting plate 9 and the fixed limiting plate 22 are also fixed together. Under the combined action of the rotating limiting plate 9 and the fixed limiting plate 22, the water intake pipe 8 will not tilt. Meanwhile, due to the multiple rolling balls 23 arranged inside the relative circumferences of the sliding plate 2 and the rotating plate 12, the multiple rolling balls 23 roll along the outer wall of the water intake pipe 8 during the descent of the water intake pipe 8, without affecting the relative descent of the water intake pipe 8.

[0017] Specifically, the insulation mechanism includes a water intake pipe 8, a heat insulation layer 24, and heat insulation cotton 25. Two heat insulation layers 24 are fixedly connected to the inner side of the water intake pipe 8, and heat insulation cotton 25 is fixedly connected inside the two heat insulation layers 24. In this embodiment, when there is hot spring water inside the water intake pipe 8, the heat insulation cotton 25 can relatively keep its temperature, while the heat insulation layer 24 is conducive to the dissipation of temperature.

[0018] Specifically, the limiting mechanism includes a limiting spring 13, a sliding limiting plate 19, a guide post 16, a fixed baffle 18, a wellhead 17, and an auxiliary plate 14. A wellhead 17 is provided on the base plate 15. Multiple fixed baffles 18 are fixedly connected to the base plate 15. Sliding limiting plates 19 are provided outside the multiple fixed baffles 18. Guide posts 16 penetrating the fixed baffles 18 are fixedly connected to the inner sides of each of the multiple sliding limiting plates 19. The other end of the guide post 16 is fixedly connected to the auxiliary plate 14. A limiting spring 13 is sleeved on the outside of the guide post 16. Both ends of the limiting spring 13 are fixedly connected to the auxiliary plate 14 and the fixed baffle 18, respectively. In this embodiment, as the water intake pipe 8 gradually descends, the water intake pipe 8... The bottom end will gradually approach the multiple auxiliary plates 14. When the bottom end of the water intake pipe 8 contacts the inside of the top of the multiple auxiliary plates 14 at the same time, since the water intake pipe 8 is still gradually descending, the multiple auxiliary plates 14 will slide away from the water intake pipe 8 under the action of the water intake pipe 8 gradually descending. This will cause the guide post 16 to slide along the middle of the fixed baffle 18, thereby causing the sliding limit plate 19 to gradually move away from the fixed baffle 18 and causing the limit spring 13 to gradually contract under force. This will allow the outside of the water intake pipe 8 to completely enter the wellhead 17, thereby enabling the water intake pipe 8 to descend stably. At the same time, under the action of the overall device, the water intake pipe 8 can be kept to descend relatively vertically to facilitate the extraction of hot spring water.

[0019] Specifically, the diameter of the groove opening of the limiting groove 26 is relatively smaller than the diameter of the rolling ball 23, and the rolling ball 23 will not fall outside the limiting groove 26. In this embodiment, it is beneficial to make the rolling ball 23 roll, and at the same time, it is also beneficial to prevent the rolling ball 23 from falling outside the limiting groove 26, so that the water intake pipe 8 maintains a relatively stable descent.

[0020] Specifically, the rotating limiting plate 9 and the fixed limiting plate 22 are provided with through holes that are slightly larger than the outer diameter of the water intake pipe 8. In this embodiment, the outer wall of the water intake pipe 8 will not be completely and tightly fitted inside the rotating limiting plate 9 and the fixed limiting plate 22, thereby reducing the friction generated during the descent of the water intake pipe 8.

[0021] Specifically, the upper ends of the multiple auxiliary plates 14 are provided with inclined grooves, which are slightly smaller than the outer diameter of the water intake pipe 8. In this embodiment, during the descent of the water intake pipe 8, it is beneficial to correct the relative position of the water intake pipe 8 and also to facilitate the sliding of the multiple auxiliary plates 14, thereby enabling the water intake pipe 8 to remain relatively vertical during descent.

[0022] Working principle and usage process of the present invention: Before use, the base plate 15 of this invention, a medium-deep geothermal well insulation and water extraction structure, simply needs to be placed on the ground surface and made to fit tightly against it. Multiple counterweights are then placed on the surface of the base plate 15 to maintain relative stability. During use, the operator simply drives the motor 6. By adjusting the motor 6, the threaded rod 5 can be rotated, causing the sliding plate 2 to slide up and down inside the working box 4. When the sliding plate 2 reaches a certain position, the motor 6 stops driving, and the sliding spring 7 keeps the sliding plate 2 in position. For relative stability, the construction workers need to vertically place the water intake pipe 8 against one end of the fixed limiting plate 22 and one end of the sliding plate 2. When the water intake pipe 8 is stably placed inside, the rotating plate 12 and the rotating limiting plate 9 are moved together by the rotating shaft 21, so that the first fixed plate 10 is tightly attached to one end of the sliding plate 2, and the second fixed plate 20 is tightly attached to one end of the fixed limiting plate 22. Then, by tightening the fixing bolts 11, the rotating plate 12 and the sliding plate 2 are fixed together, and the rotating limiting plate 9 and the fixed limiting plate 22 are also fixed together. Under the combined action of the positioning plate 22, the water intake pipe 8 will not tilt. Simultaneously, due to the multiple rolling balls 23 arranged inside the relative circumferences of the sliding plate 2 and the rotating plate 12, the multiple rolling balls 23 roll along the outer wall of the water intake pipe 8 during its descent, without affecting the relative descent of the water intake pipe 8. When there is hot spring water inside the water intake pipe 8, the insulation cotton 25 can relatively keep its temperature warm, while the insulation layer 24 facilitates heat dissipation. As the water intake pipe 8 gradually descends, its bottom end will gradually approach the multiple auxiliary plates 14. When the bottom end of the water intake pipe 8 approaches the multiple auxiliary plates 14... When the top of the auxiliary plate 14 contacts the inside simultaneously, the water intake pipe 8 is still gradually descending. As the water intake pipe 8 descends, the auxiliary plates 14 slide away from the water intake pipe 8, causing the guide post 16 to slide along the middle of the fixed baffle 18. This causes the sliding limit plate 19 to gradually move away from the fixed baffle 18, and the limit spring 13 to gradually contract under force. This allows the outside of the water intake pipe 8 to completely enter the wellhead 17, thus enabling the water intake pipe 8 to descend stably. At the same time, under the action of the overall device, the water intake pipe 8 can be kept relatively vertical during descent, facilitating the extraction of hot spring water.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
