[0002] The sucker rod is a slender rod in an oil well. It connects to the polished rod at the top and the oil pump at the bottom, transmitting power. The sucker rod is generally made of low-carbon alloy steel that has undergone quenching and tempering. It is connected one by one in the tubing with internal threaded clamps and extends to the piston at the underground oil layer. It pumps oil through reciprocating motion. The current oil well length is generally around two thousand meters. Taking Shengli Oilfield as an example, the deepest one has reached more than three thousand meters. Cleaning equipment is needed when repairing sucker rods.

[0003] Existing methods for cleaning sucker rods involve using high-pressure water jets to rinse and clean the rods after use. However, these methods have several drawbacks: a simple rinsing approach is insufficient to remove firmly adhered oil and impurities from the outside of the sucker rod, and personnel must move around to adjust the nozzle and rinse the entire outer circumference of the moving rod, resulting in poor cleaning effectiveness and convenience. Therefore, this application proposes a repaired sucker rod cleaning device to address these problems. Utility Model Content

[0017] like Figures 1 to 4 As shown in this embodiment, a cleaning device for repairing sucker rods includes: The base 1 has mounting holes at its four top corners, and an electric slide rail module 101 is fixedly installed on its top left side. The mounting holes are provided for personnel to install and fix the base 1 to an external mobile vehicle, trolley, or other location that needs to be fixed during fixed applications using external bolts. The cleaning fluid storage tank 102 is fixedly connected between the top of the base 1 and the right side of the electric slide rail module 101. A water pump 103 is fixedly installed on its top. The water inlet of the water pump 103 extends into the cleaning fluid storage tank 102 and is connected to a water suction pipe. The water outlet of the water pump 103 is connected to a hose 104. The rotary support and rotary drive steering assembly is fixedly connected to the left side of the moving end of the electric slide rail module 101, and a rectangular box 2 is fixedly connected to its left end. The left side of the rectangular box 2 is set as an opening. The arc-shaped outer shell 3 is fixedly connected to the left side of the rectangular box 2, and its front, back and bottom are all set as openings; The notch-type ring guide assembly consists of two sets, both fixedly connected inside the arc-shaped housing 3. The same arc-shaped brush 4 is fixedly fitted inside the two notch-type ring guide assemblies. The rotary support and rotary drive directional adjustment assembly is used to adjust the orientation of the arc-shaped housing 3 longitudinally, so as to further flexibly adjust the placement and cleaning orientation of the arc-shaped housing 3 and the arc-shaped brush 4 according to the verticality of the sucker rod wellhead or the external horizontality during repair. The notch-type ring guide assembly is used to guide the arc-shaped brush 4 in a circular direction. The reciprocating rotary drive assembly is installed inside the rectangular box 2 and embedded and fixed on the outside of the arc-shaped brush 4. The reciprocating rotary drive assembly is used to drive the arc-shaped brush 4 to rotate back and forth. When the arc-shaped brush 4 is sleeved on the outside of the sucker rod, its reciprocating rotation is used to achieve effective friction brushing and cleaning of the entire outer circle of the sucker rod. The notch-type front and rear flushing assembly is fixedly installed on the front and rear sides of the rectangular box 2 and connected and fixed to the left end of the hose 104; the notch-type front and rear flushing assembly is used to synchronously flush and clean the front and rear positions of the sucker rod when the water pump 103 is started. In this embodiment, a water inlet pipe is fixedly connected to the top right side of the cleaning fluid storage tank 102, a connecting seat is fixedly connected between the top left side of the cleaning fluid storage tank 102 and the right side of the electric slide rail module 101, and a filter screen is fixedly connected to the bottom end of the suction pipe.

[0018] Furthermore, such as Figure 1 and 2 As shown, the rotary support and rotary drive steering assembly includes a circular support 201, a rotating shaft 203, and a brake motor 202. The circular support 201 is fixedly connected to the left side of the moving end of the electric slide rail module 101. The rotating shaft 203 is rotatably embedded in the left side of the circular support 201. The left end of the rotating shaft 203 is welded and fixed to the right side of the rectangular box 2. The brake motor 202 is fixedly installed on the right inner wall of the circular support 201. The output shaft of the brake motor 202 is fixedly connected to the right end of the rotating shaft 203. In this embodiment, a first circular hole is provided on the left side of the U-shaped support 201, and two first bearings are fixedly sleeved in the first circular hole. The inner ring of the first bearing is fixedly sleeved with the outer side of the rotating shaft 203, so as to achieve the effect of rotating the rotating shaft 203. In this implementation scheme, the rotary support 201, the rotating shaft 203, and the brake motor 202 work together to drive the rotating shaft 203 to rotate. The rotating shaft 203 drives the rectangular box 2 to rotate longitudinally. The rectangular box 2 further drives the arc-shaped outer shell 3 and the arc-shaped brush 4 to rotate, adjusting them to be vertical or horizontal. This allows for flexible adjustment of the arc-shaped outer shell 3 and the arc-shaped brush 4 for cleaning applications when repairing the sucker rod at the wellhead vertically or horizontally. The adjustable horizontal and vertical application not only facilitates the repair of sucker rods placed horizontally externally, but also allows for cleaning of the outside of sucker rods that are vertically lifted at the wellhead, improving the applicability of the field application.

[0019] Furthermore, such as Figure 2 and 4 As shown, the notch-type ring guide assembly includes an arc-shaped guide rail 302 and an arc-shaped slider 301. Both arc-shaped guide rails 302 are fixedly connected to the inner side of the arc-shaped outer shell 3, and both arc-shaped sliders 301 are fixedly connected to the outer side of the arc-shaped brush 4. The outer side of the arc-shaped slider 301 is provided with a guide rail groove with both ends open. The arc-shaped slider 301 is slidably mounted on the corresponding arc-shaped guide rail 302 through the guide rail groove. In this embodiment, the arc-shaped guide rail 302 and the arc-shaped slider 301 work together, and the arc-shaped slider 301 guides the arc-shaped guide rail 302 in a circular direction through the guide rail groove, so as to achieve the effect of guiding the arc-shaped brush 4 in a circular direction.

[0020] Furthermore, such as Figure 1 and 2 As shown, the reciprocating rotary drive assembly includes an arc-shaped rack 401, a first gear 402, two torsion springs 403, a support shaft, half gears 404, and a drive motor 405. The arc-shaped rack 401 is embedded and fixed on the outside of the arc-shaped brush 4. The support shaft is fixedly connected between the front and rear inner walls of the rectangular box 2. The first gear 402 is rotatably sleeved on the support shaft. The left side of the first gear 402 meshes with the right side of the arc-shaped rack 401. The two torsion springs 403 are respectively fixedly connected to the front and rear sides of the first gear 402. 03 The repulsive ends are fixedly connected to the front inner wall and the rear inner wall of the rectangular box 2 respectively. The two torsion springs 403 are movably sleeved on the support shaft. The half gear 404 meshes with the right side of the first gear 402. The area occupied by the teeth on the outer ring of the half gear 404 is equal to the area occupied by the smooth surface. The drive motor 405 is fixedly installed on the front side of the rectangular box 2. The output shaft of the drive motor 405 is fixedly connected to the front side of the half gear 404. The arc rack 401 and the first gear 402 are both located between the two arc sliders 301. In this embodiment, a second circular hole is provided at the center of the front side of the first gear 402, and a second bearing is fixedly sleeved in the second circular hole. The inner ring of the second bearing is fixedly sleeved with the outer side of the support shaft, so as to achieve the effect of rotating and installing the first gear 402. A rectangular through hole is provided on the right side of the arc-shaped outer shell 3. The first gear 402 is located in the rectangular through hole and does not contact its inner wall, so as to allow the first gear 402 to pass through. In this embodiment, the arc-shaped rack 401, the first gear 402, the two torsion springs 403, the support shaft, the half gear 404, and the drive motor 405 work together. The drive motor 405 drives the half gear 404 to rotate, and the half gear 404 drives the first gear 402, which meshes with it, to rotate in the opposite direction. When the first gear 402 rotates, it torsional tensions and stores energy in the two torsion springs 403. When the half gear 404 rotates to the second half turn, its teeth separate from the teeth of the first gear 402. At this time, the elastic force of the two torsion springs 403, which are in a torsional tension state, drives the first gear 402 to rotate back to its original position. With the continuous rotation of the half gear 404, the elastic energy storage and rotation of the two torsion springs 403 work together to achieve the effect of driving the first gear 402 to reciprocate. The first gear 402 drives the arc-shaped brush 4 to reciprocate through the arc-shaped rack 401 meshing with it. When the arc-shaped brush 4 is attached to the outside of the sucker rod, its reciprocating rotation achieves effective friction and brushing cleaning of the entire outer circle of the sucker rod.

[0021] Furthermore, such as Figure 1 , 2 As shown in Figures 3 and 4, the notch-type front and rear confining assembly includes two arc-shaped tubes 5 with both ends sealed and a U-shaped tube 501 connected and fixed between the tops of the two. The two arc-shaped tubes 5 are respectively fixedly connected to the left front side and the left rear side of the rectangular box 2. The arc-shaped outer shell 3 is located between the two arc-shaped tubes 5. Multiple nozzles 502 are connected and fixed in a ring at equal intervals on the inner side of the arc-shaped tubes 5. The right side of the arc-shaped tube 5 located on the front side is connected and fixed to the left end of the hose 104. In this implementation scheme, two arc-shaped pipes 5, a U-shaped pipe 501, and multiple nozzles 502 work together. When the water pump 103 starts, it draws cleaning water from the cleaning fluid storage tank 102 through the suction pipe and pumps it into the hose 104. The water then enters the arc-shaped pipe 5 on the front side through the hose 104, and is then diverted to the arc-shaped pipe 5 on the rear side through the U-shaped pipe 501. Finally, it is sprayed out by multiple nozzles 502 on the front and rear sides, surrounding and rinsing the outside of the sucker rod. By using the integrated front and rear side rinsing method, the effect of integrated and synchronous rinsing and cleaning of the sucker rod before and after brushing is achieved. The rinsing of the position before brushing can pre-wash away the loosely adhered dirt and oil, and wet the outside of the sucker rod. The second rinsing after brushing can further wash away the brushed residue. By using the reciprocating rotating brush combined with the integrated rinsing and cleaning method before and after brushing, the cleaning effect of the sucker rod is effectively improved.

[0022] Furthermore, the outer side of the arc-shaped brush 4 is provided with an arc-shaped insert groove that is welded to the inner side of the arc-shaped rack 401. The notch formed between the two sides of the arc-shaped brush 4, the opening at the bottom of the arc-shaped outer shell 3, and the notch formed between the two ends of the arc-shaped tube 5 all face downwards. The notch is provided to allow the sucker rod to enter into or move out of the arc-shaped brush 4 during movement.

[0023] It should be noted that the electric slide rail module 101 preferably uses the Feichuang FCL250-FC7-1S linear guide slide module. This product uses a linear motor for direct drive and has the characteristics of large stroke and strong load-bearing capacity. Regarding power supply, given that the sucker rod application site is the actual site, with multiple oil recovery processes, water injection, and other electrical equipment, and that the site has corresponding long-term mains power supply facilities, the power supply conditions are sufficient and feasible. All electrical components of this device are connected to the mains power on site, and are directly powered through conventional power distribution devices such as extension cords and circuit breakers. This power supply scheme is a conventional power supply method for industrial electrical equipment and is a mature and well-known technology, which will not be elaborated here. In addition, given that the drive motor 405 and the brake motor 202 are vertically moving components, the power cords or extension cords connected to them are conventionally designed with appropriate bending lengths to meet their displacement requirements.

[0024] The usage method of this embodiment is as follows: When using the cleaning device for repairing sucker rods, the provided mounting holes allow personnel to install and fix the base 1 to an external mobile vehicle, trolley, or other location requiring fixation during application using external bolts. Personnel operate the electric slide rail module 101 to drive the U-shaped support 201 downwards. The U-shaped support 201, through the rotating shaft 203, rectangular box 2, and arc-shaped outer shell 3, drives the arc-shaped brush 4 to engage with the outside of the sucker rod through its notch. As the sucker rod passes through the inside of the arc-shaped brush 4, personnel start the water pump 103 and drive motor 405. When the drive motor 405 starts, it drives the half gear 404 to rotate. The half gear 404 drives the first gear 402, which meshes with it, to rotate in the opposite direction. When the first gear 402 rotates, it torsional tensions and stores energy in the two torsion springs 403. When the half gear 404 rotates to the second half turn, its teeth separate from the teeth of the first gear 402. At this time, the elastic force of the two torsion springs 403, which are in a torsional tension state, drives the first gear 402 to rotate back to its original position. As the half gear 404 continues to rotate, in conjunction with the elastic energy storage and rotational synergy of the two torsion springs 403, the effect of driving the first gear 402 to rotate back and forth is achieved. The first gear 402 drives the arc-shaped brush 4 to rotate back and forth through the arc-shaped rack 401 meshing with it. The arc-shaped brush 4 drives the two arc-shaped sliders 301 to rotate back and forth on the two arc-shaped guide rails 302. The arc-shaped guide rails 302 guide the arc-shaped sliders 301 to work in a circular direction. When the arc-shaped brush 4 is sleeved on the outside of the sucker rod, its reciprocating rotation is used to achieve effective friction brushing and cleaning of the entire outer circle of the sucker rod. When the water pump 103 starts, it draws cleaning water from the cleaning fluid storage tank 102 through the suction pipe and pumps it into the hose 104. The water then enters the front arc-shaped pipe 5 through the hose 104, and is then diverted to the rear arc-shaped pipe 5 through the U-shaped pipe 501. Finally, it is sprayed out through multiple nozzles 502 on both the front and rear sides, surrounding and rinsing the outside of the sucker rod. By using the integrated front and rear side rinsing method, the sucker rod is cleaned simultaneously before and after brushing. The rinsing before brushing can wash away loosely adhered dirt and oil, and wet the outside of the sucker rod. The second rinsing after brushing can further remove the brushed residue. The reciprocating rotating brush combined with the integrated rinsing method before and after brushing effectively improves the cleaning effect of the sucker rod. Moreover, the rinsing method eliminates the need for personnel to walk back and forth to adjust the nozzles 502 to rinse the entire circumference of the moving sucker rod, improving the cleaning effect and convenience. Furthermore, since there are two states for on-site repair of sucker rods: one is direct maintenance and repair when the rod is pulled out of the wellhead, and the other is horizontal relocation and support repair using a moving support after the rod is removed during a major overhaul, the cleaning process required for direct maintenance and repair when the rod is pulled out of the wellhead can be addressed by pre-activating the brake motor 202 to drive the rotating shaft 203 to rotate. The rotating shaft 203 drives the rectangular box 2 to rotate longitudinally, which in turn drives the arc-shaped outer shell 3 and the arc-shaped brush 4 to rotate, thus adjusting the rod to a vertical position. This allows for flexible adjustment and switching between horizontal ferrule cleaning and vertical ferrule cleaning. When the device is in a vertical position, it can be moved to the vertical sucker rod position at the wellhead using an external vehicle or trolley, with the arc-shaped brush 4 clipped to its outside. Then, the drive motor 405 and water pump 103 can be started to perform integrated rotary brushing cleaning and surrounding flushing. This allows for flexible adjustment of the brush flushing direction based on whether the sucker rod is vertically lifted or horizontally moved for repair. With adjustable horizontal and vertical applications, it is not only suitable for sucker rods repaired horizontally but also for cleaning the outside of sucker rods lifted vertically at the wellhead, improving its applicability in the field.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
