[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention sets the first and second cleaning heads as a double-sided umbrella structure, and the umbrella structure can be retracted and extended by an electric push rod to meet the needs of pipes with different diameters. During the movement of the cleaning head into the oil pipeline, two sets of laser ranging probes located at the end of the cleaning head at an angle can detect the pipe diameter based on the distance the laser reaches the inner wall of the pipe, combined with an angle algorithm. Because it is set at an angle, it can detect changes in the diameter of the inner wall of the pipe in advance. When the inner flange or diameter change section of the pipe weld is detected, the laser ranging probe can promptly feed back a signal to the controller. The microcontroller in the controller drives the motor on the electric push rod to run. First, it controls the outer umbrella mechanism on the first cleaning head to retract inward with the retraction of the electric push rod and the pulling action of the transmission frame. At this time, the inner umbrella mechanism of the first cleaning head is still tightly attached to the inner wall of the oil pipeline, and water will not overflow. When the outer umbrella mechanism passes through the flange or enters the straightening section, the electric push rod used to drive the outer umbrella mechanism extends again, so that the outer umbrella mechanism unfolds and re-attaches to the inner wall of the oil pipeline. At the same time, it is used for The electric push rod controlling the inner umbrella mechanism retracts, causing the inner umbrella mechanism to close inwards. At this time, the outer umbrella mechanism re-fits against the inner wall of the pipe, preventing water overflow and ensuring the seal between the first and second cleaning heads at all times. The scraper mechanism and ultrasonic vibration mechanism between the first and second cleaning heads also have a certain degree of retraction. The scraper adopts an arc-shaped structure, which on the one hand fits smoothly against the inner wall of the pipe, and on the other hand, when there are inward flanges or diameter changes in the inner wall of the pipe, the arc-shaped scraper transitions more smoothly. When pressure is applied, the arc-shaped scraper can retract under the action of the telescopic outer tube and the telescopic inner tube, and under the elastic action of the first spring, it always adheres to the pipe wall to ensure the scraping effect. When the ultrasonic transducer is subjected to pressure applied by the flange or diameter change section inside the pipe, it can retract under the action of the damping rod, and under the elastic action of the second spring, it adheres to the inner wall of the pipe to ensure the cleaning effect. This solves the problem that existing PE and PPR pipe ends have flange structures during welding, and the traditional pig body is easily blocked by the flange during the movement, which leads to inconvenience in use.

[0023] 2. The cleaning device of the present invention has certain energy-saving characteristics. When the first cleaning head and the second cleaning head move under the action of air pressure difference, the blades in the protective nets at both ends can rotate under the action of aerodynamic pressure and aerodynamic resistance, thereby driving the drive shaft and the drive gear on the outer wall of the drive shaft to rotate. The drive gear meshes with the driven gears at the ends of multiple generators around it to generate electrical energy and store it in the battery to meet the energy consumption requirements of the device.

[0033] Also includes:

[0034] The transmission rod chamber 13 is installed inside the first cleaning head 1 and the second cleaning head 2. Fixed rings 14 are installed on the outer walls of both ends of the transmission rod chamber 13. Transmission frames 15 are installed around the outer walls of the fixed rings 14.

[0037] The scraper mechanism 6 is installed in the middle of the outer wall of the ultrasonic power supply chamber 5, and ultrasonic vibration mechanisms 7 are provided on both sides of the scraper mechanism 6.

[0038] Please see Figure 2 A protective net cover 11 is installed on the outer wall of the outer umbrella mechanism 9. Laser ranging probes 12 are installed at the upper and lower ends of the outer wall of the protective net cover 11. The laser ranging probes 12 are tilted towards the inner wall of the oil pipeline. When the first cleaning head 1 and the second cleaning head 2 move under the action of air pressure difference, the laser ranging probes 12, which are tilted at the ends, can detect the diameter of the pipeline based on the distance of the laser to the inner wall of the pipeline and in combination with the tilt angle algorithm. Because it is tilted, it can detect the change in the diameter of the inner wall of the pipeline in advance and feed back the signal to the controller.

[0039] Please see Figure 3The transmission rod chamber 13 is equipped with a partition 26, and the protective net cover 11 is equipped with a blade 24. The rear end of the blade 24 is equipped with a transmission shaft 25. One end of the transmission shaft 25 passes through and extends into the transmission rod chamber 13, and is rotatably connected to the partition 26 through a bearing 27. A drive gear 28 is installed on the outer wall of the transmission shaft 25, and generators 29 are arranged around the outside of the transmission shaft 25. A driven gear 20 is installed at the end of the rotor shaft of the generator 29, and the rotor shaft of the generator 29 is connected to the drive gear 28 through the meshing of the driven gear 20. When the first cleaning head 1 and the second cleaning head 2 move under the action of air pressure difference, the blades 24 in the protective net covers 11 at both ends can rotate under the action of aerodynamic pressure and aerodynamic resistance, thereby driving the transmission shaft 25 and the drive gear 28 on the outer wall of the transmission shaft 25 to rotate. Electricity is generated by the meshing of the drive gear 28 with the driven gears 20 at the ends of the multiple generators 29 around the shaft.

[0041] Please see Figure 3 A controller is installed on the outer wall of the battery 30. The controller contains a microcontroller chip, a GPS positioning module and a wireless data transmission module. The microcontroller chip can be used to control the operation of the electric push rod 19 and the ultrasonic generator 708, and to feed back the positioning information of the GPS positioning module to the user terminal in real time through the wireless data transmission module.

[0042] Please see Figure 5Multiple scraper mechanisms 6 are provided, and these multiple scraper mechanisms 6 are evenly distributed around the outer wall of the ultrasonic power supply chamber 5. Each mechanism includes a telescopic outer tube 601, a telescopic inner tube 602, a scraper head 604, and an arc-shaped scraper 605. One end of the telescopic outer tube 601 is fixedly connected to the ultrasonic power supply chamber 5. The telescopic inner tube 602 is located inside the telescopic outer tube 601, and one end of the inner tube 602 extends to the outside of the outer tube 601. The scraper head 604 is installed at one end of the inner tube 602. A first spring 603 is provided on the outside of the inner tube 602, and both ends of the first spring 603 are respectively connected to the outer tube 601 and the scraper head 605. The blade head 604 is connected, and the arc-shaped scraper 605 is installed at one end of the scraper head 604. When the first cleaning head 1 and the first connecting head 3 move under the action of air pressure difference, the scraper mechanism 6 in the middle can move to scrape off the dirt on the inner wall of the oil pipeline. The scraper adopts an arc-shaped structure, which on the one hand fits flat against the inner wall of the pipeline, and on the other hand, when there is an inner flange or a diameter change section on the inner wall of the pipeline, the arc-shaped scraper 605 transitions relatively smoothly. When subjected to the pressure applied by the inner flange or the diameter change section, the arc-shaped scraper 605 can retract under the action of the telescopic outer tube 601 and the telescopic inner tube 602, and under the elastic action applied by the first spring 603, it always fits against the pipe wall to ensure the scraping effect.

[0043] Please see Figure 1 and Figure 6Each of the two ultrasonic oscillation mechanisms 7 has twelve ultrasonic transducer seats 703, which are staggered. An ultrasonic transducer 705 is installed inside each ultrasonic transducer seat 703. An oscillation plate 706 is installed on the outside of the ultrasonic transducer 705 and is fixedly connected to the ultrasonic transducer seat 703. Damping rods 702 are installed on both sides of the lower end of the ultrasonic transducer seat 703, with one end of each damping rod fixedly connected to the outer wall of the ultrasonic power supply chamber 5. Second springs 704 are installed outside the damping rods 702, with both ends of each spring connected to the ultrasonic transducer seat 703 and the ultrasonic power supply chamber 5, respectively. An ultrasonic generator 708 is installed inside the ultrasonic power supply chamber 5. The output end of the device 708 is electrically connected to the input end of the ultrasonic transducer 705. Clean water is pre-filled between the first cleaning head 1 and the second cleaning head 2. During movement, the distance between the first cleaning head 1 and the second cleaning head 2 remains unchanged, thereby promoting the movement of the water. During the process, the microcontroller chip in the controller drives the ultrasonic transducer 705 to operate. The ultrasonic transducer 705 sends a signal to the ultrasonic transducer 705, which converts the acoustic energy of the ultrasonic frequency source into mechanical vibration, driving the vibrating plate 706 to vibrate at high frequency. Together with the clean water, it effectively cleans the inner wall of the oil pipeline. When subjected to pressure from the flange or diameter change section inside the pipeline, the ultrasonic transducer seat 703 can contract under the action of the damping rod 702 and adhere to the inner wall of the pipeline under the elastic action of the second spring 704, ensuring the cleaning effect.

[0044] Please see Figure 6 The outer wall of the vibrating plate 706 is provided with several micro-vibrating balls 707. The micro-vibrating balls 707 convert the surface vibration of the vibrating plate 706 into multiple point vibrations, which increases the vibration pressure applied to the inner wall of the oil pipeline, thereby achieving a more efficient cleaning effect.

[0045] Please see Figure 6 Adjacent ultrasonic transducer seats 703 are connected by a rubber connecting layer 709. The second spring 704 is provided with a rubber sleeve 701, which can protect the second spring 704.

[0046] Please see Figure 1 and Figure 4Both the first connector 3 and the second connector 4 include a positioning seat 21 and a cover block 22. Both sides of the cover block 22 are connected to the positioning seat 21 by screws 23. The positioning seat 21 and the cover block 22 are both provided with a hemispherical groove 31. The rear end of the hemispherical groove 31 is provided with a conical groove 32. The interior of the hemispherical groove 31 is provided with a ball joint 33. The rear end of the ball joint 33 in the first connector 3 is fixedly connected to the second connector 4 by a first connecting rod 34. The rear end of the ball joint 33 in the second connector 4 is fixedly connected to the ultrasonic power supply chamber 5 by a second connecting rod 35. The connector part is connected by a ball joint 33. When the first cleaning head 1 and the second cleaning head 2 move in the oil pipeline, when passing through the bending section, the ball joint 33 allows the connection to have a certain range of rotation, thereby adapting to the bending angle of the pipeline and allowing the first cleaning head 1 and the second cleaning head 2 to pass smoothly.

[0047] Working principle: Before use, place the first cleaning head 1 and the second cleaning head 2 inside the oil pipeline. Using the valve on the pipe wall, fill the space between the first cleaning head 1 and the second cleaning head 2 with clean water. The first cleaning head 1 and the second cleaning head 2 are connected by a first connector 3 and a second connector 4. A scraper mechanism 6 and an ultrasonic vibration mechanism 7 are installed at the connection point. The connectors are fixed together using a detachable ball joint structure. Depending on the total length of the oil pipeline, the number of connectors can be increased or decreased to adjust the volume of clean water filled between the first cleaning head 1 and the second cleaning head 2. After filling, compressed air is injected into the oil pipeline through a pressure valve on the pipe wall at the end of the second cleaning head 2. Under the action of the air pressure difference, the first cleaning head 1, the second cleaning head 2, and the clean water trapped between them are agitated. As the system moves along the pipeline, the scraper mechanism 6 scrapes away dirt from the inner wall of the oil pipeline. Meanwhile, the microcontroller chip in the controller drives the ultrasonic transducer 705. The ultrasonic transducer 705 sends signals to itself, converting the acoustic energy of the ultrasonic source into mechanical vibration, which in turn causes the vibrating plate 706 and the micro-vibrating balls 707 on its surface to vibrate at high frequency. This, combined with clean water, efficiently cleans the inner wall of the oil pipeline. During the movement, two sets of laser ranging probes 12, tilted at the ends of the first cleaning head 1 and the second cleaning head 2, can detect the pipeline diameter based on the distance the laser reaches the inner wall of the pipeline, using an angle algorithm. Because of their tilted design, they can detect changes in the diameter of the inner wall of the pipeline in advance. When a welded joint is detected... When the inner flange or diameter change section is reached, the laser ranging probe 12 can promptly feed back a signal to the controller. The microcontroller in the controller drives the motor on the electric push rod 19 to operate. First, it controls the outer umbrella mechanism 9 located on the first cleaning head 1 to retract inward with the retraction of the electric push rod 19 and the pulling action of the transmission frame 15. At this time, the inner umbrella mechanism 10 of the first cleaning head 1 is still tightly attached to the inner wall of the oil pipeline, and water will not overflow. When the outer umbrella mechanism 9 passes through the flange or enters the straightening section, the electric push rod 19 used to drive the outer umbrella mechanism 9 extends again, causing the outer umbrella mechanism 9 to unfold and re-attach to the inner wall of the oil pipeline. At the same time, the electric push rod 19 used to control the inner umbrella mechanism 10 retracts, causing the inner umbrella mechanism 10 to retract inward. At this time, the outer umbrella mechanism... 9. The scraper re-fits against the inner wall of the pipe, preventing water overflow and ensuring a constant seal between the first cleaning head 1 and the second cleaning head 2. The scraper mechanism 6 and the ultrasonic vibration mechanism 7 between the first cleaning head 1 and the second cleaning head 2 also have a certain degree of retraction. The scraper adopts an arc-shaped structure, which ensures a smooth fit against the inner wall of the pipe. Furthermore, when there are inward flanges or diameter changes in the inner wall of the pipe, the arc-shaped scraper 605 transitions smoothly. When subjected to pressure from the inward flanges or diameter changes, the arc-shaped scraper 605 retracts under the action of the telescopic outer tube 601 and the telescopic inner tube 602, and under the elastic action of the first spring 603, it remains in contact with the pipe wall, ensuring effective scraping. Similarly, the ultrasonic transducer seat 703, when subjected to pressure from the inward flanges or diameter changes in the pipe...The device can retract under the action of the damping rod 702 and adhere to the inner wall of the pipe under the elastic action of the second spring 704, ensuring the cleaning effect. When the first cleaning head 1 and the second cleaning head 2 move to the end of the oil pipeline, the drain valve on the pipe wall and the oil pipeline cover are opened to discharge the sewage and the pushed dirt, thus completing the pipeline cleaning. In addition, the cleaning device has certain energy-saving characteristics. When the first cleaning head 1 and the second cleaning head 2 move under the action of air pressure difference, the blades 24 in the protective net covers 11 at both ends can rotate under the action of pneumatic pressure and pneumatic resistance, thereby driving the drive shaft 25 and the drive gear 28 on the outer wall of the drive shaft 25 to rotate. The drive gear 28 meshes with the driven gears 20 at the ends of multiple generators 29 around it to generate electrical energy, which is stored in the battery 30 to meet the energy consumption requirements of the device.
