Abstract
Description
Technical Field
[0001] This invention belongs to the field of descaling equipment technology, specifically a descaling system for geothermal power generation wells. Background Technology
[0002] Geothermal power generation is a new type of power generation technology that uses underground hot water and steam as a power source. Its basic principle is similar to that of thermal power generation. It is also based on the principle of energy conversion, first converting geothermal energy into mechanical energy, and then converting mechanical energy into electrical energy.
[0003] However, in existing technologies, long-term use of geothermal power wells can lead to scaling inside the well, which in turn changes the inner diameter of the well and affects the actual use effect. Existing cleaning equipment mostly uses spraying reagents and scraping with hard structures. Different cleaning methods use different existing equipment, which increases the actual cleaning cost. At the same time, due to the influence of the internal environment of geothermal power wells, the service life of existing electrical equipment inside can be easily affected, resulting in poor actual use effect of existing cleaning equipment.

Each limiting frame has a limiting bolt threaded to one side of its inner surface. Each limiting bolt has a limiting frame rotatably connected to one end. Each limiting frame has two bidirectional threaded rods rotatably connected to one side of its outer surface. Each set of limiting wheels has two wheels. Each set of two limiting wheels is threaded to the outer surface of the corresponding bidirectional threaded rod. The linkage component is located on the limiting frame and the limiting wheels.
[0007] Each of the limiting frames has multiple first support wheels rotatably connected at equal intervals on its inner bottom surface. Two sets of limiting rods slide through the outer surfaces of the two limiting frames. Each set of limiting rods has two rods. Each set of two limiting plates is slidably fitted onto the outer surface of the two limiting rods. Each set of two limiting plates is slidably inserted between the outer surfaces of the two limiting plates. Each limiting rod and the outer surface of the lifting bolt are threaded with multiple nuts.

Each linkage gear meshes with the corresponding limiting gear.
[0009] The extension mechanism includes two extension frames and two scrapers. The top ends of the two extension frames are slidably inserted between the two limiting frames. The outer surface of each extension frame is in contact with the top of the corresponding first support wheel. An extension strip is fixedly connected to one side of the inner wall of each extension frame. An extension tube is fixedly connected to one end of each extension strip. A stop rod is slidably embedded inside each extension tube. An extension rod is threaded to one end of each stop rod. The two scrapers are respectively threaded to one end of the corresponding extension rod.
[0010] Each of the extension frames has a rotating bar fixedly connected to the inner wall of one side, the rotating bar meshing with the rotating wheel, and multiple second support wheels rotatably connected at equal intervals on the outer surface of each extension frame. Each extension tube is equipped with a limit spring inside.
[0011] The conveying mechanism includes two base frames and a conveying component. The outer surfaces of the two base frames are in contact with the tops of the corresponding second support wheels. Multiple third support wheels are rotatably connected to each outer surface of the base frame at equal intervals. A third connecting shaft is rotatably connected to the inner wall of one of the base frames. A first rotating gear and a second rotating gear are sleeved on the outer surface of the third connecting shaft. The conveying component is disposed on the two base frames.
[0012] The conveying component includes two conveying frames, two liquid guiding frames, and two rotating blades. The two conveying frames are fixedly connected by bolts, and the two conveying frames are sleeved on the outer surface of two bottom frames. One of the conveying frames has a liquid injection pipe connected to its top, and the other conveying frame has multiple liquid drainage frames connected to its bottom.

Guide bars are fixedly connected to the top surface inside the two conveying frames, and each guide bar is in contact with the outer surface of the corresponding rotating rack.
[0014] A method for using a descaling system for a geothermal power generation well includes the following steps: S1. Scratching Treatment: During use, insert the existing rotating rod body into the geothermal power generation well, ensuring the bottom of the rotating rod body reaches the required cleaning depth. Then, by rotating the limit bolt, the limit bolt, in conjunction with the limit frame, presses the limit wheel tightly against the outer surface of the drill rod body. Simultaneously, connect it to the existing suspension equipment via the lifting bolt. Then, by releasing and lifting the existing suspension equipment, the limit mechanism can reciprocate up and down along the outer surface of the drill rod body. During this process, the limit wheel, which is tightly against the outer surface of the drill rod body, will rotate synchronously. Then, the rotating limit wheel, in conjunction with the connecting gear, the limit gear, the first connecting shaft, the connecting bevel gear, and the second connecting shaft, can drive the rotating wheel to rotate. Then, under the support of the first support wheel, the rotating wheel, in conjunction with the rotating bar, can synchronously drive the extension frame to rotate. Then, the rotating extension frame, in conjunction with the extension bar, the extension tube, the push rod, and the extension rod, can drive the scraper to rotate. Then, the scraper can scrape and rub the dirt on the inner wall of the geothermal power generation well, thereby increasing the surface roughness of the dirt, simultaneously loosening the dirt, and increasing the surface contact area of the dirt. S2. Solution Spraying: The solution is connected to the existing pipeline and solution delivery equipment via an injection pipe, allowing the existing solution delivery equipment to inject the cleaning solution into the delivery frame under pressure through the injection pipe, and simultaneously into the guide frame through the drain frame. During this process, the third support wheel supports the rotating blade to rotate following the flowing cleaning solution. The rotating blade, in conjunction with the rotating rack, the first rotating gear, the third connecting shaft, and the second rotating gear, drives the connecting rack to rotate. The rotating rack, in conjunction with the extension frame, synchronously drives the rotating bar to rotate. During the rotation of the rotating bar, the cleaning solution inside the guide frame is sprayed through the drain port along the tangential direction of the guide frame edge onto the outer surface of the dirt on the inner wall of the geothermal power generation well. This ensures that the cleaning solution can fully contact the dirt treated by the scraper. Furthermore, during the reciprocating movement of the limiting mechanism, the cleaning solution will fully spray the dirt on the inner wall of the geothermal power generation well.
[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: (1) In this invention, during use, the existing rotating rod body is inserted into the geothermal power generation well so that the bottom end of the rotating rod body can reach the required cleaning depth. Then, by rotating the limiting bolt, the limiting bolt and the limiting frame squeeze the limiting wheel tightly against the outer surface of the drill rod body. At the same time, it is connected to the existing suspension equipment through the lifting bolt. Then, by releasing and lifting the existing suspension equipment, the limiting mechanism can move back and forth along the outer surface of the drill rod body. During this process, the limiting wheel that is close to the outer surface of the drill rod body will rotate synchronously. The rotating limit wheel, in conjunction with the connecting gear, limit gear, first connecting shaft, connecting bevel gear, and second connecting shaft, drives the rotating wheel to rotate. Supported by the first support wheel, the rotating wheel, in conjunction with the rotating bar, synchronously drives the extension frame to rotate. The rotating extension frame, in conjunction with the extension bar, extension tube, push rod, and extension rod, drives the scraper to rotate. This allows the scraper to scrape and rub the scale on the inner wall of the geothermal well, thereby increasing the surface roughness of the scale, simultaneously loosening the scale, and increasing the surface contact area. By connecting the injection pipe to existing pipelines and solution delivery equipment, the existing solution delivery equipment can inject the cleaning solution into the delivery frame under pressure through the injection pipe, and simultaneously inject it into the guide frame through the drain frame. During this process, the third support wheel supports the rotating blade to rotate along with the flowing cleaning solution. The rotating blade, in conjunction with the rotating rack, the first rotating gear, the third connecting shaft, and the second rotating gear, drives the connecting rack to rotate. The rotating rack, in conjunction with the extension frame, synchronously drives the rotating bar to rotate. During the rotation of the rotating bar, the cleaning solution inside the guide frame is sprayed through the drain port along the tangential direction of the guide frame edge onto the outer surface of the dirt on the inner wall of the geothermal power generation well. This ensures that the cleaning solution fully contacts the dirt treated by the scraper. As the limiting mechanism moves up and down, the cleaning solution is thoroughly sprayed onto the dirt on the inner wall of the geothermal power generation well, while the scraper accelerates the dissolution of the dirt. This effectively prevents existing electrical equipment from entering the geothermal power generation well, enabling the equipment to efficiently perform its intended functions.
[0016] (2) In this invention, the time interval between the two corresponding limit wheels can be conveniently adjusted by rotating the bidirectional threaded rod, so that the limit wheels can fit more fully against the outer surface of the drill pipe body of different sizes, thereby improving the practical applicability of the equipment. Under the support of the limit spring, the push rod and the extension rod can squeeze the scraper to fit against the dirt on the inner wall of the geothermal power generation well, so that the equipment can adapt to different scaling conditions inside the geothermal power generation well. Under the support of the second support wheel, the bottom frame can still maintain its original state during the rotation of the extension frame, so that the equipment can meet the use of geothermal power generation wells with different scaling conditions, thereby improving the practical applicability of the equipment and effectively reducing the actual cleaning cost.

The linkage components include a first linkage shaft, a second linkage shaft, two limit gears 107, two linkage gears 106, and a rotating wheel 108. The first linkage shaft is rotatably connected to the corresponding... One side of the outer surface of the limiting frame 103, and one end of the first connecting shaft slides through one side of the outer surface of the limiting frame 103. A connecting bevel gear is sleeved on the outer surface of the first connecting shaft. Two limiting gears 107 are sleeved on the outer surface of the first connecting shaft. The second connecting shaft is rotatably connected to the bottom of one of the limiting frames 103. A connecting bevel gear is also sleeved on the outer surface of the second connecting shaft. The two connecting bevel gears mesh. A rotating wheel 108 is sleeved on the outer surface of the second connecting shaft. Two connecting gears 106 are respectively fixedly connected to one side of the outer surface of the corresponding limiting wheel 105. Each connecting gear 106 meshes with the corresponding limiting gear 107. The existing rotating rod body is inserted into the geothermal power generation well, so that the rotating rod... The bottom of the main body can reach the required cleaning depth. Then, by rotating the limiting bolt 102, the limiting bolt 102 and the limiting frame 103 squeeze the limiting wheel 105 to fit tightly against the outer surface of the drill rod body 4. At the same time, it is connected to the existing suspension equipment through the lifting bolt 109. Then, by releasing and lifting the existing suspension equipment, the limiting mechanism 1 can move back and forth along the outer surface of the drill rod body 4. During this process, the limiting wheel 105, which is close to the outer surface of the drill rod body 4, will rotate synchronously. Then, the rotating limiting wheel 105, in conjunction with the connecting gear 106, the limiting gear 107, the first connecting shaft, the connecting bevel gear, and the second connecting shaft, can drive the rotating wheel 108 to rotate. Please see Figure 6 and Figure 7The extension mechanism 2 is used to accelerate the removal of dirt. The extension mechanism 2 is mounted on the limiting mechanism 1 and includes two extension frames 201 and two scrapers 208. The top ends of the two extension frames 201 are slidably inserted between the two limiting frames 101.

A stop rod 206 is slidably embedded inside each extension tube 205. An extension rod 207 is threadedly connected to one end of each stop rod 206. The two scrapers 208 are respectively threadedly connected to one end of the corresponding extension rod 207. Each extension frame... A rotating bar 203 is fixedly connected to the inner wall of one side of the extension frame 201. The rotating bar 203 meshes with the rotating wheel 108. Multiple second support wheels 202 are equidistantly rotatably connected to the outer surface of each extension frame 201. Each extension tube 205 is equipped with a limit spring. Under the support of the first support wheel 110, the rotating wheel 108 and the rotating bar 203 can synchronously drive the extension frame 201 to rotate. Then, the rotating extension frame 201, together with the extension bar 204, extension tube 205, push rod 206 and extension rod 207, drives the scraper 208 to rotate. This allows the scraper 208 to scrape and rub the dirt on the inner wall of the geothermal power generation well, thereby increasing the surface roughness of the dirt, simultaneously loosening the dirt and increasing the surface contact area of the dirt. Please see Figures 8-13The conveying mechanism 3 is used to convey the solution for dirt treatment. The conveying mechanism 3 is mounted on the extension mechanism 2. The conveying mechanism 3 includes two base frames 301 and a conveying component. The outer surfaces of the two base frames 301 are in contact with the tops of the corresponding second support wheels 202. Multiple third support wheels 307 are rotatably connected at equal intervals to the outer surface of each base frame 301. A third connecting shaft is rotatably connected to the inner wall of one of the base frames 301. A first rotating gear 308 and a second rotating gear 309 are sleeved on the outer surface of the third connecting shaft. The conveying component is mounted on the two base frames 301 and includes two conveying frames 302, two liquid guiding frames 310, and two rotating blades 305. The two conveying frames 302 are fixedly connected to the two base frames 301 by bolts, and the two conveying frames 302 are sleeved on the two base frames 301. 1. On the outer surface, one of the conveying frames 302 has a liquid injection pipe 304 connected to its top, and the other conveying frame 302 has multiple drain frames 313 connected to its bottom. The bottom end of each drain frame 313 is connected to the top of a corresponding guide frame 310. The two guide frames 310 are fixedly connected to the outer surface of the corresponding bottom frame 301. Each guide frame 310 has a slidingly embedded linkage rack 311 at its bottom. Each linkage rack 311 has multiple extension frames fixedly connected at equal intervals at its bottom. Each extension frame has a slidingly inserted linkage bolt at its bottom. The tops of the multiple linkage bolts are threaded with rotating bars 312. Two rotating blades 305 are slidably inserted inside the two conveying frames 302. Each rotating blade 305 has a fixedly connected rotating rack 306 at its top. Each third support wheel One side of each of the three support wheels 307 extends into the interior of the corresponding conveying frame 302. The outer surface of one side of each third support wheel 307 is in contact with the outer surface of the corresponding rotating blade 305. One side of the first rotating gear 308 extends into the interior of the corresponding conveying frame 302, and the first rotating gear 308 meshes with the rotating rack 306. The second rotating gear 309 meshes with the connecting rack 311. One side of each of the two rotating bars 312 extends into the interior of the corresponding liquid guiding frame 310. Multiple drain ports are equidistantly provided on the outer surface of one of the rotating bars 312. Guide bars 303 are fixedly connected to the top surface inside each of the two conveying frames 302. Each guide bar 303 is in contact with the outer surface of the corresponding rotating rack 306. The system is connected to the existing solution conveying equipment via an injection pipe 304 in conjunction with existing pipelines, thereby enabling the existing solution to be conveyed... The delivery equipment pressurizes and injects the cleaning solution into the delivery frame 302 through the injection pipe 304, and simultaneously injects it into the guide frame 310 through the drain frame 313. During this process, the third support wheel 307 supports the rotating blade 305 to rotate along with the flowing cleaning solution. The rotating blade 305, in conjunction with the rotating rack 306, the first rotating gear 308, the third connecting shaft, and the second rotating gear 309, drives the connecting rack 311 to rotate. In turn, the rotating connecting rack 311, in conjunction with the extension frame, synchronously drives the rotating bar 312 to rotate. As the rotating bar 312 rotates, the cleaning solution inside the guide frame 310 is sprayed through the drain port along the tangential direction of the edge of the guide frame 310 onto the outer surface of the dirt on the inner wall of the geothermal power generation well.This ensures the cleaning solution makes full contact with the dirt treated by the scraper 208, and then, during the reciprocating movement of the limiting mechanism 1, the cleaning solution is thoroughly sprayed onto the dirt on the inner wall of the geothermal power generation well.
[0022] The following describes in detail the method of using a descaling system for a geothermal power well provided by an embodiment of the present invention. The method of use includes the following steps: Step 1, Scratching Treatment: During use, insert the existing rotating rod body into the geothermal power generation well, ensuring the bottom of the rotating rod body reaches the required cleaning depth. Then, by rotating the limiting bolt 102, the limiting bolt 102, in conjunction with the limiting frame 103, presses the limiting wheel 105 tightly against the outer surface of the drill rod body 4. Simultaneously, connect it to the existing suspension equipment via the lifting bolt 109. Then, by releasing and lifting the existing suspension equipment, the limiting mechanism 1 can reciprocate up and down along the outer surface of the drill rod body 4. During this process, the limiting wheel 105, which is tightly against the outer surface of the drill rod body 4, will rotate synchronously, thereby causing the rotating limiting wheel 105 to... 05, in conjunction with the connecting gear 106, the limiting gear 107, the first connecting shaft, the connecting bevel gear, and the second connecting shaft, can drive the rotating wheel 108 to rotate. Then, under the support of the first support wheel 110, the rotating wheel 108, together with the rotating bar 203, can synchronously drive the extension frame 201 to rotate. Then, the rotating extension frame 201, together with the extension bar 204, the extension tube 205, the push rod 206, and the extension rod 207, can drive the scraper 208 to rotate. This allows the scraper 208 to scrape and rub the dirt on the inner wall of the geothermal power generation well, thereby increasing the surface roughness of the dirt, simultaneously loosening the dirt, and increasing the surface contact area of the dirt. Step 2, Solution Spraying: The injection pipe 304 is connected to the existing pipeline and solution delivery equipment, enabling the existing solution delivery equipment to inject the dirt cleaning solution into the delivery frame 302 under pressure through the injection pipe 304, and simultaneously into the guide frame 310 through the drain frame 313. During this process, the third support wheel 307 supports the rotating blade 305 to rotate along with the flowing cleaning solution. The rotating blade 305, in conjunction with the rotating rack 306, the first rotating gear 308, the third connecting shaft, and the second rotating gear 309, drives the connecting rack 311 to rotate, thereby causing the rotating connecting rack... 311 can work in conjunction with the extension frame to synchronously drive the rotating bar 312 to rotate. During the rotation of the rotating bar 312, the cleaning solution inside the liquid guide frame 310 will be sprayed through the drain port along the tangential direction of the edge of the liquid guide frame 310 onto the outer surface of the dirt on the inner wall of the geothermal power generation well. This allows the cleaning solution to fully contact the dirt treated by the scraper 208. Then, during the reciprocating movement of the limiting mechanism 1, the cleaning solution will fully spray the dirt on the inner wall of the geothermal power generation well. At the same time, the scraper 208 can accelerate the dissolution of the dirt and effectively prevent existing electrical equipment from entering the geothermal power generation well, so that the equipment can efficiently perform its intended functions.
[0023] The time interval between the two limiting wheels 105 can be easily adjusted by rotating the bidirectional threaded rod 104, so that the limiting wheels 105 can fit more fully against the outer surface of the drill pipe body 4 of different sizes, improving the practical applicability of the equipment. Under the support of the limiting spring, the abutment rod 206 and the extension rod 207 can squeeze the scraper 208 to fit against the dirt on the inner wall of the geothermal power generation well, so that the equipment can adapt to different scaling conditions inside the geothermal power generation well. Under the support of the second support wheel 202, the bottom frame 301 can still maintain its original state during the rotation of the extension frame 201, so that the equipment can meet the use of geothermal power generation wells with different scaling conditions, improving the practical applicability of the equipment while effectively reducing the actual cleaning cost.

10. A method for using a descaling system for a geothermal power generation well, characterized in that, The descaling system applied to a geothermal power well as described in claim 9 includes the following steps: S1. Scraping Treatment: During use, insert the existing rotating rod body into the geothermal power generation well so that the bottom of the rotating rod body can reach the required cleaning depth. Then, by rotating the limiting bolt (102), the limiting bolt (102) and the limiting frame (103) squeeze the limiting wheel (105) tightly against the outer surface of the drill rod body (4). At the same time, it is connected to the existing suspension equipment through the lifting bolt (109). Then, by releasing and lifting the existing suspension equipment, the limiting mechanism (1) can move back and forth along the outer surface of the drill rod body (4). During this process, the limiting wheel (105) tightly against the outer surface of the drill rod body (4) will rotate synchronously, and then the rotating limiting wheel (105) will be engaged with the limiting wheel (105) to form a swivel joint. The connecting gear (106), the limiting gear (107), the first connecting shaft, the connecting bevel gear and the second connecting shaft can drive the rotating wheel (108) to rotate. Then, under the support of the first support wheel (110), the rotating wheel (108) and the rotating bar (203) can synchronously drive the extension frame (201) to rotate. Then, the rotating extension frame (201) and the extension bar (204), extension tube (205), push rod (206) and extension rod (207) can drive the scraper (208) to rotate. Then, the scraper (208) can scrape and rub the dirt on the inner wall of the geothermal power generation well, thereby increasing the surface roughness of the dirt, simultaneously loosening the dirt and increasing the surface contact area of the dirt. S2, Solution Spraying: The solution is connected to the existing pipeline and solution delivery equipment via the injection pipe (304), enabling the existing solution delivery equipment to inject the dirt cleaning solution into the delivery frame (302) under pressure through the injection pipe (304), and simultaneously into the guide frame (310) through the drain frame (313). During this process, the third support wheel (307) supports the rotating blade (305) to rotate following the flowing cleaning solution. The rotating blade (305) then engages with the rotating rack (306), the first rotating gear (308), the third connecting shaft, and the second... The rotating gear (309) drives the linkage rack (311) to rotate, which in turn enables the rotating linkage rack (311) to work with the extension frame to drive the rotating bar (312) to rotate synchronously. During the rotation of the rotating bar (312), the cleaning solution inside the liquid guide frame (310) will be sprayed through the drain port along the tangential direction of the edge of the liquid guide frame (310) to the outer surface of the dirt on the inner wall of the geothermal power generation well, so that the cleaning solution can fully contact the dirt treated by the scraper (208). Then, during the reciprocating movement of the limiting mechanism (1), the cleaning solution will fully spray the dirt on the inner wall of the geothermal power generation well.
