Description

Technical Field

[0001] This utility model relates to the field of geothermal drilling technology, specifically a cleaning device for geothermal drilling. Background Technology

[0002] Geothermal drilling is used to drill wells for geothermal steam and geothermal water. It is an important and special technology and an essential means of exploring and extracting geothermal fluids. During the drilling process, a lot of stains are left on the well wall. If these stains are not removed, the entire geothermal well will become unusable. Therefore, cleaning equipment for geothermal drilling is indispensable.

[0003] An existing patent (publication number: CN216841569U) discloses a cleaning device for geothermal drilling, including four columns. An installation mechanism is fixedly connected to the upper end of the four columns. A lifting mechanism is fixedly connected inside the top of the installation mechanism. A connecting mechanism is fixedly connected to the lower end of the lifting mechanism. A cleaning mechanism is fixedly connected inside the connecting mechanism. The beneficial effects of this utility model are: by setting a stepper motor, drive rod, and take-up roller, it is convenient to drive the connecting rope to descend, thereby adjusting the descent of the connecting plate and hollow tube, which is convenient for descending geothermal wells of different depths. At the same time, by setting a drive motor and mounting hole, the rotating rod is driven to rotate. The rotating rod drives the threaded fan blade, turntable, and four cleaning plates to rotate. During the descent, the turntable and cleaning plates continuously and quickly clean the well wall and lower end of the well. Meanwhile, the dirt on the well wall and the lower end is quickly discharged through the threaded fan blade and the discharge pipe. The cleaning speed is slow. In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. Existing well wall cleaning methods usually involve manually cleaning the well wall with special hand-held cleaning tools. This cleaning method is not only slow, but also significantly increases the labor intensity of workers, thereby reducing the work efficiency of well wall cleaning; 2. The cleaning brushes of the cleaning device will wear out during the cleaning of the well wall. Existing cleaning devices cannot adjust the cleaning brushes, causing the brushes to wear out after prolonged use and no longer be able to contact the well wall. This results in the brushes being unable to effectively clean the well wall, thus significantly reducing the cleaning effect of the well wall and affecting subsequent cleaning work. Utility Model Content

[0004] The purpose of this utility model is to provide a cleaning device for geothermal drilling, in order to solve the problems mentioned in the background art. The existing well wall cleaning methods usually involve manual cleaning with special cleaning tools. This cleaning method is not only slow, but also greatly increases the labor intensity of workers, thereby reducing the work efficiency of well wall cleaning. In addition, the existing cleaning devices cannot adjust the cleaning brush, which causes the brush to wear out after long-term use and no longer be in contact with the well wall, thus making it impossible for the brush to effectively clean the well wall and affecting subsequent cleaning work. To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for geothermal drilling, comprising a housing assembly and a mounting base. A motor is disposed at the center of the bottom of the mounting base, and a cleaning seat is disposed on the output shaft of the motor. A servo motor is embedded in the top of the cleaning seat. Connecting shafts are disposed at both ends of the cleaning seat via bearings. A main bevel gear is disposed outside the connecting shafts. Three positioning plates are disposed at the center of the bottom of the cleaning seat. Lead screws are disposed on one side of each of the three positioning plates via bearings. Moving blocks are disposed outside the three lead screws. Guide blocks are disposed at the bottom of each of the three moving blocks. Connecting rods are disposed at both ends of one side of each of the three moving blocks. Cleaning brush plates are disposed at the ends of the two connecting rods furthest from the moving blocks. A secondary bevel gear is disposed at one end of each of the three lead screws. Three guide grooves are formed on the outer side of the bottom of the cleaning seat.

[0005] More preferably, the outer casing assembly includes a shaft mounted on the two inner walls of the housing via bearings, two winding reels mounted on the outside of the shafts, traction ropes mounted on the outside of the two winding reels, and a traction motor mounted on one side of the housing.

[0006] More preferably, the extended end of the traction rope is fixedly connected to the mounting base.

[0007] More preferably, the central axis of the motor is aligned with the central axis of the cleaning seat.

[0008] More preferably, the main bevel gear and the three auxiliary bevel gears are meshed together.

[0009] More preferably, the connecting rod and the cleaning seat are configured to slide together.

[0010] More preferably, the internal dimensions of the three guide grooves are consistent with the external dimensions of the three guide blocks.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this invention, the combination of an electric motor, a cleaning seat, and a cleaning brush plate enables the geothermal drilling cleaning device to quickly clean the well wall during use, greatly increasing the convenience of cleaning the well wall, thereby reducing the labor intensity of workers and improving the work efficiency of cleaning the geothermal drilling well wall.

[0013] In this invention, the servo motor, main bevel gear, and secondary bevel gear work together to adjust the position of the cleaning brush plate during use. This solves the problem that the cleaning brush plate cannot effectively clean the geothermal well wall after prolonged use and wear, thus significantly improving the cleaning effect of the geothermal well wall and ensuring that subsequent cleaning work is not affected. This meets the requirements of the geothermal drilling cleaning device. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a cleaning device for geothermal drilling, including a housing assembly 1 and a mounting base 2. A motor 3 is provided at the middle of the bottom end of the mounting base 2. A cleaning seat 4 is provided on the output shaft of the motor 3. A servo motor 5 is embedded in the top of the cleaning seat 4. A connecting shaft 6 is provided at both ends of the cleaning seat 4 through bearings. A main bevel gear 7 is provided on the outside of the connecting shaft 6. Three positioning plates 8 are provided at the middle of the bottom end of the cleaning seat 4. A lead screw 9 is provided on one side of the three positioning plates 8 through bearings. A moving block 10 is provided on the outside of the three lead screws 9. A guide block 11 is provided at the bottom end of the three moving blocks 10. A connecting rod 12 is provided at both ends of one side of the three moving blocks 10. A cleaning brush plate 13 is provided at the end of the two connecting rods 12 away from the moving block 10. A secondary bevel gear 14 is provided at one end of the three lead screws 9. Three guide grooves 15 are opened on the outside of the bottom end of the cleaning seat 4.

[0021] In this embodiment, as Figure 1 As shown, the housing assembly 1 includes a housing 101 with a rotating shaft 102 mounted on the two inner walls via bearings. Two winding reels 103 are mounted on the outside of the rotating shaft 102, and a traction rope 104 is mounted on the outside of the two winding reels 103. A traction motor 105 is mounted on one side of the housing 101.

[0022] In this embodiment, as Figure 2 As shown, the extended end of the traction rope 104 is fixedly connected to the mounting base 2; this allows for adjustment of the lifting and lowering of the cleaning seat 4, thereby increasing the convenience of the cleaning device during use.

[0023] In this embodiment, as Figure 2 As shown, the central axis of the motor 3 is aligned with the central axis of the cleaning seat 4; this enables rapid cleaning of the well wall of the geothermal well, greatly increasing the convenience of cleaning the well wall of the geothermal well, thereby reducing the labor intensity of the workers and improving the work efficiency of cleaning the well wall of the geothermal well.

[0024] In this embodiment, as Figure 3 As shown, the main bevel gear 7 and the three secondary bevel gears 14 are meshed together; this allows for adjustment of the position of the cleaning brush plate 13, solving the problem that the cleaning brush plate 13 cannot effectively clean the geothermal well wall after prolonged use and wear, thus significantly improving the cleaning effect of the geothermal well wall and ensuring that subsequent cleaning work is not affected, thereby meeting the requirements of the cleaning device for geothermal drilling.

[0025] In this embodiment, as Figure 4 As shown, the connecting rod 12 and the cleaning seat 4 are connected by a sliding connection; this makes the cleaning brush plate 13 move in a single direction, avoiding any deviation of the cleaning brush plate 13 during movement, thereby increasing the stability of the cleaning brush plate 13 during use.

[0026] In this embodiment, as Figure 3 As shown, the internal dimensions of the three guide grooves 15 and the external dimensions of the three guide blocks 11 are consistent, which prevents the moving block 10 from rotating with the lead screw 9 during movement, thereby greatly improving the stability of the moving block 10 during movement.

[0027] The method of use and advantages of this utility model: When using this geothermal drilling cleaning device, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, by pushing the handle, the housing 101 is moved to the upper end of the geothermal well with the help of the casters. Then, the traction motor 105 is started by the controller. At this time, the traction motor 105 drives the winding reel 103 to rotate through the rotating shaft 102, causing the traction rope 104 wound on the winding reel 103 to move the mounting base 2 downward. At the same time, the mounting base 2 drives the cleaning brush plate 13 to move downward synchronously through the motor 3 and the cleaning seat 4, and moves the cleaning brush plate 13 down into the geothermal well, so that the brush edge of the cleaning brush plate 13 is in contact with the well wall of the geothermal well. Then, the motor 3 is started by the controller. At this time, the motor 3 drives the three cleaning brush plates 13 to rotate through the cleaning seat 4, so that the cleaning brush plates 13 can quickly clean the well wall of the geothermal well, greatly increasing the convenience of cleaning the well wall of the geothermal well, thereby reducing the labor intensity of the workers and improving the work efficiency of cleaning the well wall of the geothermal well. When the brush plate 13 wears or becomes worn after prolonged cleaning of the well wall, the servo motor 5 is activated by the controller. At this time, the servo motor 5 drives the main bevel gear 7 to rotate through the connecting shaft 6. The main bevel gear 7 meshes with and drives the three secondary bevel gears 14 to rotate. The three secondary bevel gears 14 drive the lead screw 9 to rotate. The three lead screws 9 drive the moving blocks 10 to move under the cooperation of the guide block 11 and the guide groove 15. At the same time, the three moving blocks 10 drive the cleaning brush plate 13 to move horizontally through the two connecting rods 12, so that the brush edge of the cleaning brush plate 13 is once again in contact with the well wall of the geothermal drilling, and the cleaning brush plate 13 continues to clean the well wall. This solves the problem that the cleaning brush plate 13 cannot effectively clean the well wall of the geothermal drilling after prolonged use and wear, which would prevent it from contacting the well wall. This greatly improves the cleaning effect of the geothermal drilling well wall, so as not to affect the subsequent cleaning work, and thus meets the requirements of the cleaning device for geothermal drilling.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
