Detailed Description of the Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 5, the present utility model provides a technical solution: a tubing descaling device, including a machine body 1 and a base 2. The machine body 1 is fixedly installed on the top of the base 2. A bracket 4 is fixedly installed on the top of the base 2. A motor 3 is fixedly installed on the surface of the machine body 1, and the motor 3 is connected to a power source. An expansion rod 5 is arranged inside the machine body 1, and the expansion rod 5 is electrically connected to the motor 3. A plurality of scraping plates 6 are slidably installed at the free end of the expansion rod 5. A first spring is arranged between the scraping plate 6 and the expansion rod 5. An adapter plate 7 is sleeved between two adjacent scraping plates 6. A second spring is arranged between the adapter plate 7 and the scraping plate 6. After the expansion rod 5 drives the scraping plate 6 into the tubing and then resets, the reset scraping plate 6 pushes the dirt in the tubing into the machine body 1, completing the cleaning of the dirt inside the tubing.

[0023] A fixing ring 8 is fixedly installed on the surface of the machine body 1. A plurality of clamping blocks 9 are rotatably installed on the surface of the machine body 1 near the fixing ring 8. A first torsion spring is arranged between the clamping block 9 and the machine body 1. An arc surface 10 is arranged at one end of the clamping block 9. A rotating ring 11 is rotatably installed on the surface of the machine body 1. A plurality of abutting rods 12 are fixedly installed on the surface of the rotating ring 11 near the clamping block 9. The bottom of the abutting rod 12 contacts the arc surface 10. The clamping block 9 clamps the tubing, and the clamping block 9 and the bracket 4 play a role in fixing the tubing, preventing the tubing from shaking during the cleaning process and affecting the cleaning effect.

[0024] The bracket 4 is arranged in an arc shape and is aligned with the machine body 1 and fits the surface of the tubing, improving the support for the tubing.

[0025] One end inner wall of the machine body 1 near the bracket 4 is set as an inclined surface, enabling the scraping plate 6 to smoothly enter the inside of the tubing and return to the inside of the machine body 1 through the inclined surface.

[0026] A slide rail 14 is fixedly installed on the surface of the base 2. A collection groove 15 is arranged inside the slide rail 14. An opening is provided at the top of the collection groove 15. A discharge port 13 is provided on the surface of the machine body 1. The discharge port 13 is aligned with the opening on the surface of the collection groove 15. A slide rod 16 is slidably installed at the discharge port 13. A third spring is arranged between the slide rod 16 and the machine body 1. A pressing plate 17 is hinged at the bottom of the slide rod 16. A second torsion spring is arranged between the pressing plate 17 and the slide rod 16. A abutting block 18 is fixedly installed on the surface of the expansion rod 5. An inclined surface is arranged at the bottom of the abutting block 18. After the scraping plate 6 pushes the dirt inside the tubing into the machine body 1, the dirt will fall into the collection groove 15 through the discharge port 13 for centralized storage.

[0027] The cross-sectional area of the pressing plate 17 is smaller than the opening area on the surface of the collection groove 15. When the expansion rod 5 resets and presses the slide rod 16, the slide rod 16 drives the pressing plate 17 into the collection groove 15 to compact the dirt in the collection groove 15, improving the utilization rate of the internal space of the collection groove 15.

[0028] Place the used oil pipe on the surface of the bracket 4, and push the placed oil pipe towards the body 1 so that the pipe orifice of the oil pipe contacts and fits with the surface of the fixing ring 8. At this time, the inner wall of the pipe orifice of the oil pipe fits with the outer wall of the body 1. Rotate the rotating ring 11 to drive the abutting rod 12 to rotate. The rotating abutting rod 12 moves away from the arc surface 10 of the clamping block 9, releasing the limit on the clamping block 9. The released clamping block 9 rotates under the elastic force of the first torsion spring and contacts the surface of the oil pipe to clamp the oil pipe, preventing the oil pipe from shaking during the cleaning process and affecting the cleaning effect of the dirt. After fixing the oil pipe, turn on the power supply of the motor 3 to start the motor 3. The started motor 3 drives the free end of the telescopic rod 5 to extend and contract, making the telescopic rod 5 perform a reciprocating motion. When the telescopic rod 5 extends, the free end of the telescopic rod 5 drives the scraping plate 6 to move towards the oil pipe until the scraping plate 6 completely enters the interior of the oil pipe. Under the control of the control unit, the scraping plate 6 moves outwards to make the scraping plate 6 completely fit with the pipe wall, increasing the contact area with the pipe wall and improving the cleaning effect of the scraping plate 6 on the dirt inside the oil pipe. When the telescopic rod 5 contracts, the free end of the telescopic rod 5 drives the scraping plate 6 to move back towards the body 1. The moving scraping plate 6 reaches the interior of the body 1 through the inclined surface on the inner wall of the body 1 and pushes the dirt in the oil pipe into the interior of the body 1, completing the cleaning of the residual dirt on the inner wall of the oil pipe. The reset scraping plate 6 pushes the dirt to the discharge port 13, and the dirt falls into the collection tank 15 through the discharge port 13 for centralized storage, facilitating the staff to centrally process the dirt and preventing the dirt from scattering to other working areas and affecting normal work. At the same time, during the process of the telescopic rod 5 driving the scraping plate 6 to reset, the moving free end of the telescopic rod 5 drives the abutting block 18 to move towards the sliding rod 16 until the bottom inclined surface of the abutting block 18 contacts the top of the sliding rod 16. The bottom inclined surface of the abutting block 18 squeezes and pushes the sliding rod 16 to move downwards. The moving sliding rod 16 drives the pressing plate 17 to move towards the collection tank 15. When the moving pressing plate 17 reaches the collection tank 15, it tampers the dirt collected in the collection tank 15, compressing the overall volume of the dirt in the collection tank 15, improving the space utilization rate inside the collection tank 15, preventing the staff from frequently replacing the collection tank 15, and improving work efficiency.
