Description

Technical Field

[0001] This utility model relates to the field of descaling equipment technology, and in particular to a descaling equipment for the inner wall of a geothermal well. Background Technology

[0002] A geothermal well is a deep-hole well used to extract underground thermal energy. It penetrates the strata to reach the thermal reservoir and includes wellhead equipment, well casing and filter pipe. It is a key facility for the development and utilization of geothermal energy.

[0003] After prolonged use, geothermal wells accumulate a large amount of scale, silt, and mineral deposits on their inner walls. This buildup reduces geothermal transfer efficiency and hinders fluid flow. Therefore, it is necessary to clean the scale and other dirt from the inner walls in a timely manner. Geothermal well descaling equipment can use high-pressure water flushing and mechanical scraping techniques to precisely and efficiently remove the dirt, restore the normal operating efficiency of the geothermal well, and ensure the sustainable use of geothermal resources.

[0004] However, existing descaling equipment for the inner wall of geothermal wells has the following shortcomings:

[0005] In existing technologies, the descaling components of geothermal well descaling equipment are mostly fixed on rigid supports at the front end of the equipment body. Therefore, they can only descale geothermal wells of a specific diameter. However, the actual diameter of geothermal wells varies. When dealing with geothermal wells of different diameters, the descaling components are difficult to adjust adaptively, which hinders the operation of the equipment. Either the descaling components cannot reach the well wall, or they scrape excessively against the well wall. This not only reduces the descaling effect, but also easily damages the well wall and causes leakage risks.

[0006] Therefore, we propose a descaling device for the inner wall of geothermal wells to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a descaling device for the inner wall of a geothermal well. By combining the locking action of the threaded assembly with the linkage action of the connecting rod assembly, the position of the descaling assembly can be flexibly adjusted, and a stable and reliable support can be provided for the descaling assembly, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a geothermal well inner wall descaling device, comprising a rotating rod, a fixed ring movably sleeved on the outer wall of the rotating rod, three fixed screws fixedly connected to the outer wall of the fixed ring, a fixed nut threadedly connected to the outer wall of each of the three fixed screws, three fixed brackets fixedly connected to the outer wall of the rotating rod, a movable groove opened on one side of the outer wall of each of the three fixed brackets, and the outer walls of the three fixed screws movably inserted into the three movable grooves, three first connecting seats fixedly connected to the outer wall of the fixed ring, a first connecting rod movably sleeved on the outer wall of each of the three first connecting seats, a second connecting seat movably inserted into the inner wall of each of the three first connecting rods, and an arc-shaped plate fixedly connected to the outer wall of each of the three second connecting seats.

[0009] Preferably, a set of third connecting seats is fixedly connected to the outer wall of each of the three arc-shaped plates, a second connecting rod is movably sleeved on the outer wall of each of the three sets of third connecting seats, a fourth connecting seat is movably inserted into the inner wall of each of the three sets of second connecting rods, and the outer wall of the rotating rod is fixedly connected to the outer wall of the three sets of fourth connecting seats.

[0010] Preferably, a descaling brush is fixedly installed on the outer wall of each of the three arc-shaped plates, and an mounting plate is fixedly installed on the outer wall of each of the three arc-shaped plates.

[0011] Preferably, a descaling scraper is fixedly installed on one side of the outer wall of each of the three mounting plates, and a conveying pipe is fixedly inserted into the inner surface of the rotating rod.

[0012] Preferably, the output end of the conveying pipe is fixedly connected to a spray pipe.

[0013] Preferably, a set of spray heads is fixedly connected to the outer wall of the spray pipe.

[0014] Preferably, a drill rod connector is fixedly connected to the top of the rotating rod.

[0015] 1. In this utility model, through the interaction of the various components of the device, the locking effect of the threaded assembly and the linkage effect of the connecting rod assembly are combined to flexibly adjust the position of the descaling assembly and provide stable and reliable support for the descaling assembly. In this way, the equipment can perform descaling treatment on geothermal wells of different diameters. By precisely adjusting the threaded assembly, the connecting rod assembly can be driven to change the corresponding angle, thereby pushing the descaling assembly to move outward or inward, so as to ensure that the descaling assembly can closely fit the inner wall of geothermal wells of different diameters. This adaptability not only improves the versatility and flexibility of the equipment, but also ensures that the descaling effect is more accurate and efficient.

[0016] 2. In this utility model, through the interaction of the various components of the device, multiple descaling treatments are achieved on the inner wall of the geothermal well. This allows for rapid and deep cleaning of the well wall and thorough removal of stubborn dirt and deposits. This comprehensive descaling treatment ensures the smoothness and cleanliness of the inner wall of the geothermal well, thereby improving the heat exchange efficiency and service life of the geothermal well.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as shown in the attached document Figure 1 - Appendix Figure 4As shown, this utility model provides a technical solution: a geothermal well inner wall descaling device, including a rotating rod 1, a fixing ring 2 movably sleeved on the outer wall of the rotating rod 1, three fixing screws 3 fixedly connected to the outer wall of the fixing ring 2, and fixing nuts 4 threadedly connected to the outer walls of the three fixing screws 3, three fixing brackets 5 fixedly connected to the outer wall of the rotating rod 1, and a movable groove 6 opened on one side of the outer wall of each of the three fixing brackets 5, and the outer walls of the three fixing screws 3 movably inserted into the three movable grooves 6, and three first connecting rods 4 fixedly connected to the outer wall of the fixing ring 2. The outer walls of the three first connecting seats 7 are movably fitted with first connecting rods 8, the inner walls of the three first connecting rods 8 are movably inserted with second connecting seats 9, the outer walls of the three second connecting seats 9 are fixedly connected with arc-shaped plates 10, the outer walls of the three arc-shaped plates 10 are fixedly connected with a set of third connecting seats 11, the outer walls of the three sets of third connecting seats 11 are movably fitted with second connecting rods 12, the inner walls of the three sets of second connecting rods 12 are movably inserted with fourth connecting seats 13, and the outer wall of the rotating rod 1 is fixedly connected to the outer wall of the three sets of fourth connecting seats 13.

[0025] The overall effect of Embodiment 1 is as follows: During use, by loosening the three fixing nuts 4, the fixing ring 2 can be released from the fixing state of the rotating rod 1. Since the fixing ring 2 is movably sleeved on the outer wall of the rotating rod 1, the fixing ring 2 can move freely up and down around the rotating rod 1 as the axis. When the fixing ring 2 moves up or down, it will cause the angle of the three first connecting rods 8 to change. The three first connecting rods 8 will then push the position of the three arc plates 10 and the descaling component to adjust outward or inward. At the same time, the movement of the arc plates 10 will also cause the angle of the three second connecting rods 12 to change accordingly, thereby providing a more stable support for the three arc plates 10. Through the flexible telescopic design of the three arc plates 10, the descaling component can be flexibly telescopic and adjusted according to the actual diameter of the geothermal well, thereby fitting more closely to the inner wall of the geothermal well for efficient descaling treatment. This not only improves the applicability of the equipment, but also enhances its adaptability and working efficiency in various geothermal well environments.

[0026] Example 2, as Figure 2-4 As shown, descaling brushes 14 are fixedly installed on the outer walls of the three arc-shaped plates 10, mounting plates 15 are fixedly installed on the outer walls of the three arc-shaped plates 10, descaling scrapers 16 are fixedly installed on one side of the outer wall of the three mounting plates 15, a conveying pipe 17 is fixedly inserted into the inner wall of the rotating rod 1, a spray pipe 18 is fixedly connected to the output end of the conveying pipe 17, a set of nozzles 19 is fixedly connected to the outer wall of the spray pipe 18, and a drill rod connector 20 is fixedly connected to the top of the rotating rod 1.

[0027] The overall effect of Embodiment 2 is as follows: During use, firstly, three descaling scrapers 16 can effectively scrape off large pieces of dirt on the well wall. Subsequently, three descaling brushes 14 are responsible for cleaning the remaining fine dirt and residue on the well wall to ensure the initial cleaning of the well wall surface. Finally, the well wall is connected to an external water pipe through the input end of the delivery pipe 17, and a set of nozzles 19 sprays high-pressure water to deeply rinse the well wall. This combined descaling method can quickly and efficiently clean the well wall and thoroughly remove dirt and deposits from the well wall, ensuring the normal operation and long-term stability of the geothermal well.

[0028] The working principle of the entire device is as follows: First, connect the device to the external drive unit via the drill rod connector 20 to ensure smooth rotation of the rotating rod 1. Next, tightly connect the input end of the delivery pipe 17 to the output end of the external water pipe to ensure unobstructed water flow. Then, precisely adjust the positions of the three arc-shaped plates 10 according to the actual diameter of the geothermal well to be descaled. The operator must first loosen the three fixing nuts 4 to release the fixing ring 2. Then, according to the diameter of the geothermal well, the operator manually moves the fixing ring 2. The movement of the fixing ring 2 will cause a change in the angle of the three first connecting rods 8, thereby pushing the three arc-shaped plates 10 and their descaling components outwards or inwards to adapt to the diameter of the geothermal well. Simultaneously, the movement of the arc-shaped plates 10 will also cause a corresponding change in the angle of the three second connecting rods 12, forming an arc shape. Plate 10 provides more stable support. When the bristles of the three descaling brushes 14 are in close contact with the inner wall of the geothermal well, the fixing ring 2 and the three descaling brushes 14 are firmly fixed in the predetermined position by tightening the three fixing nuts 4 again. At this time, the equipment is ready to enter the geothermal well for descaling. When the rotating rod 1 starts to rotate through the external drive device and enters the geothermal well, the descaling process officially begins. First, the three descaling scrapers 16 will initially scrape off the large pieces of dirt on the well wall, effectively reducing the accumulation of dirt. Then, the three descaling brushes 14 will carefully clean the remaining fine dirt and residue on the well wall to ensure the cleanliness of the well wall surface. Finally, driven by the external water pump, high-pressure water is delivered to the delivery pipe 17 and flows through the spray pipe 18. Using a set of annular nozzles 19, high-pressure water is sprayed onto the well wall for a final comprehensive rinse.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
