Description

Technical Field

[0001] This invention relates to the field of pipe cleaning technology, and in particular to an automated pipe cleaning device and method. Background Technology

[0002] A gas spring assembly is a device that supports and adjusts external loads by changing the pressure of the internal gas, based on the compressibility of gas. The gas spring tube is a key component in the gas spring assembly, primarily used to connect and support various structures, enabling them to smoothly perform opening, closing, lifting, or tilting movements. It is typically made of metal materials (such as steel or aluminum alloy) and has a hollow internal structure to hold gas (usually compressed nitrogen) and some lubricating oil to achieve shock absorption and cushioning effects.

[0003] The design and manufacture of gas spring fittings need to take into account factors such as the pressure they can withstand, the environmental conditions of use, and the compatibility with other components they are matched with. Because spring and piston components need to be installed inside, in order to ensure the stable and smooth extension and contraction of the piston components, the inside of the gas spring fittings needs to be thoroughly cleaned before assembly to reduce the obstruction of the piston movement by dust and dirt. Currently, ultrasonic cleaning machines are mostly used for cleaning gas spring fittings. However, the inside of gas spring fittings is relatively complex and it is easy to form air bubble retention areas, which affects the cleaning effect.

[0004] Therefore, to address the above issues, an automated cleaning device can be designed that, while performing ultrasonic cleaning, incorporates oscillation and accelerated cleaning agent flow to improve the cleaning effect of gas spring fittings. Summary of the Invention

[0005] To overcome the problem that air bubbles easily form inside gas spring fittings when ultrasonic cleaning is used, resulting in poor cleaning effect.

[0006] The technical solution of this invention is as follows: an automated pipe cleaning device, comprising an ultrasonic cleaner, a frame mounted on the ultrasonic cleaner, a lifting assembly mounted on the frame, a platform assembly mounted on the lifting assembly, a first motor mounted on the platform assembly, and a bracket assembly mounted on the output end of the first motor. The lifting assembly is used to drive the platform assembly to move vertically, and the first motor is used to drive the bracket assembly to rotate at a preset angle. A first air supply assembly is mounted on the platform assembly, and a vortex assembly and a first transmission assembly are mounted on the bracket assembly. When the bracket assembly rotates, gas flows between the first air supply assembly and the first transmission assembly. The input end of the vortex assembly is connected to the output end of the first transmission assembly, and the first transmission assembly is used to drive the vortex assembly to rotate. The vortex assembly is used to accelerate the flow rate of the cleaning agent. A hoisting assembly is mounted on the bracket assembly, and a nozzle is mounted on the hoisting assembly. A second air supply assembly is mounted on the ultrasonic cleaner. When the lifting assembly drives the platform assembly to move vertically, gas flows between the nozzle and the second air supply assembly.

The platform assembly includes a lifting plate fixedly mounted on the movable machine, a hanger fixedly connected to the lifting plate, a balance beam fixedly connected to the hanger, and two base plates fixedly mounted on the balance beam. The tension sensor is mounted on the lifting plate and is used to detect the tension value of the tension spring and send a signal to the control unit of the motor. The output end of the motor is located between the two base plates, the motor is mounted on the balance beam, and the air supply assembly is mounted on the base plate.

Motor number one is used to drive the support beam to rotate at a preset angle. One end of the return torsion spring is connected to the bracket, and the other end is connected to the buckle beam. The retaining ring and buckle ring are adapted to the outer diameter of the pipe fitting. The support beam is positioned above the base plate.

[0009] Preferably, the first air supply assembly includes a first air hood mounted on a corresponding base plate, a first air supply pipe fixedly connected at one end to one of the air hoods, and a second air supply pipe connected at one end to the other first air hood. The other ends of the first and second air supply pipes are both connected to the first transmission assembly. The upper end of the first air hood is connected to the support beam. When the support beam is rotated at a preset angle, gas flows between the first air hood and the first transmission assembly through the first or second air supply pipe.

[0010] Preferably, the vortex assembly includes several turbine blades movably connected to the side platform, transmission gears fixedly connected to the corresponding turbine blades, a gear chain meshing with several transmission gears, and a driven gear fixedly connected to one of the transmission gears. The driven gear is connected to the output end of the first transmission assembly. The driven gear is used to drive the transmission gears and gear chain to continuously transmit power. The transmission gears are used to drive the turbine blades to rotate. The turbine blades are used to accelerate the flow rate of the cleaning agent. The first transmission assembly includes a first air cylinder mounted on the side platform, a first plunger movably connected inside the first air cylinder, a rocker arm movably connected at one end to the first plunger, and a linkage gear movably connected to the side platform. The other end of the rocker arm is movably connected to the eccentric position of the linkage gear. The linkage gear meshes with the driven gear. A first air supply pipe is connected to one end of the first air cylinder, and a second air supply pipe is connected to the other end of the first air cylinder. Gas in the first air hood flows into the first air cylinder through the first or second air supply pipe. The first plunger is used to drive the rocker arm to swing. The rocker arm drives the driven gear to rotate through the linkage gear.

[0011] Preferably, the second air supply assembly includes a second air hood installed on the ultrasonic cleaner, a first exhaust pipe fixedly connected to the second air hood, a first exhaust valve installed on the first exhaust pipe, a first air supply pipe fixedly connected at one end to the second air hood, a first air supply valve installed on the first air supply pipe, a third air hood installed on the ultrasonic cleaner, a second exhaust pipe fixedly connected to the third air hood, a second exhaust valve installed on the second exhaust pipe, a second air supply pipe fixedly connected at one end to the third air hood, and a second air supply valve installed on the second air supply pipe. The second air hood is configured with... Below the lifting plate, the No. 3 air hood is positioned above the lifting plate. The No. 1 tension sensor is used to send signals to the control units of the No. 1 exhaust valve, the No. 1 air supply valve, the No. 2 exhaust valve, and the No. 2 air supply valve. When the lifting plate moves downward, the No. 1 exhaust valve closes, the No. 1 air supply valve opens, the No. 2 exhaust valve opens, and the No. 2 air supply valve closes. The gas in the No. 2 air hood flows into the air nozzle through the No. 1 air supply pipe. When the lifting plate moves upward, the No. 1 exhaust valve opens, the No. 1 air supply valve closes, the No. 2 exhaust valve closes, and the No. 2 air supply valve opens. The gas in the No. 3 air hood flows into the air nozzle through the No. 2 air supply pipe.

[0012] Preferably, the ultrasonic cleaner is equipped with a No. 3 air supply assembly. When the lifting assembly drives the platform assembly to move vertically, the gas flows between the hoisting assembly and the No. 3 air supply assembly. The hoisting assembly is used to drive the nozzle to move vertically. When the platform assembly moves between preset positions H1 and H2, the nozzle and the end of the pipe are on the same horizontal plane. When the platform assembly moves from preset position H2 to preset position H3, the hoisting assembly drives the nozzle to move upward. When the platform assembly moves from preset position H3 to preset position H2, the hoisting assembly drives the nozzle to move downward. A No. 2 transmission assembly is installed on the bracket assembly, which drives the chute to move horizontally.

[0013] Preferably, the hoisting assembly includes a second air cylinder mounted on the side support rod, a second plunger movably connected in the second air cylinder, and a return spring installed in the second air cylinder. The air nozzle is mounted on the second plunger, and one end of the return spring is connected to the second air cylinder, and the other end is connected to the second plunger. When the lifting plate moves from preset position H2 to preset position H3, the hoisting assembly drives the air nozzle to move from preset position M1 to preset position M2; when the lifting plate moves from preset position H3 to preset position H2, the hoisting assembly drives the air nozzle to move from preset position M1 to preset position M2. Position M2 moves to preset position M1; the third air supply assembly includes a slide rod fixedly installed on the frame and a slide plate movably connected to the slide rod; a fourth air hood is installed on the slide plate and a flow pipe with one end connected to the fourth air hood, and the other end of the flow pipe is connected to the second air cylinder; when the lifting plate moves from preset position H2 to preset position H3, the gas in the fourth air hood flows into the second air cylinder through the flow pipe; when the lifting plate moves from preset position H3 to preset position H2, the gas in the second air cylinder flows into the fourth air hood through the flow pipe.

[0014] Preferably, the second transmission assembly includes a second motor mounted on the side support rod, a screw fixedly connected to the output end of the second motor, a second tension sensor mounted on the side support rod, and a second tension spring connected at one end to the second tension sensor. The other end of the second tension spring is connected to the air nozzle. The second tension sensor is used to detect the tension value of the second tension spring and send a signal to the second motor. The second motor is used to drive the screw to rotate. The slide is threadedly connected to the screw, and the screw is used to drive the slide to move. When the second tension sensor detects that the tension value of the second tension spring reaches F1, the motor drives the slide closer to the bottom of the side beam through the screw. When the second tension sensor detects that the tension value of the second tension spring reaches F2, the motor drives the slide away from the bottom of the side beam through the screw.

[0015] An automated pipe fitting cleaning method, employing the automated pipe fitting cleaning device described above, includes the following steps: S1: The user first flips the buckle upward to open it, fixes an appropriate number of pipe fittings to the side beam with the snap rings, and then releases the buckle. Under the action of the reset torsion spring, the buckle flips downward and presses the pipe fittings to fix them with the snap rings. S2: Start the mobile machine and control it to move downward along the track, so that the lifting plate moves from the preset position H1 to the preset position H2, and drives the pipe to gradually approach the cleaning tank of the ultrasonic cleaner. The first tension sensor detects the change in the tension value signal of the first tension spring and sends a signal to the control unit of the first exhaust valve, the first air supply valve, the second exhaust valve, and the second air supply valve, so that the first exhaust valve closes, the first air supply valve opens, the second exhaust valve opens, and the second air supply valve closes, so that the gas in the second air hood flows into the air nozzle through the first air supply pipe. At this time, the air nozzle and one end of the pipe are on the same horizontal line, that is, at the preset position M1, and the gas is discharged through the air nozzle and blown into the inside of the pipe, so that the residue in the pipe is discharged from the other end. At this time, the chute is located away from the side beam and the end of the chute extends out of the cleaning tank of the ultrasonic cleaner. The discharged residue falls into the chute and slides out along the chute. S3: When the mobile machine moves further down along the track, the lifting plate moves from the preset position H2 to the preset position H3. The lifting plate abuts against and presses against the slide plate, causing the No. 4 air hood to compress. Through the flow pipe, the gas in the No. 4 air hood flows into the No. 2 air cylinder, causing the No. 2 plunger to move upward, pulling the air nozzle from the preset position M1 to the preset position M2, away from the cleaning agent in the ultrasonic cleaner. During the process, the No. 2 tension sensor detects that the tension value of the No. 2 tension spring reaches F1 and sends a signal to the control unit of the No. 2 motor. The No. 2 motor drives the screw to rotate, controlling the slide to move closer to the bottom of the side beam. S4: When the lifting plate moves to the preset position H3, the pipe is completely immersed in the cleaning agent. At this time, the nozzle also enters the preset position M2. The first tension sensor detects the change in the tension value signal of the first tension spring and sends a signal to the control unit of the first motor. S5: The No. 1 motor outputs power to the support beam, controlling the support beam to swing back and forth in the opposite direction, causing the pipe fittings fixed by the retaining rings and buckles to swing in the cleaning agent. At the same time, the ultrasonic cleaner starts, using the cavitation effect generated by the ultrasonic waves in the cleaning agent to clean the surface and internal dirt of the pipe fittings. S6: As the support beam swings back and forth, it will squeeze the corresponding No. 1 air hood. The gas in the No. 1 air hood is introduced into the No. 1 air cylinder through the No. 1 air supply pipe or the No. 2 air supply pipe. The gas flowing out of the No. 1 air supply pipe and the No. 2 air supply pipe flows into the No. 1 air cylinder in two directions in sequence, causing the No. 1 plunger to move back and forth in the No. 1 air cylinder. The rocker arm swings in two directions in sequence. The rocker arm controls the linkage gear to rotate. Through the meshing of the linkage gear and the driven gear, the transmission gear and the gear chain are driven to run continuously, driving the turbine fan blade to rotate at high speed, rolling the cleaning agent and accelerating the flow of the cleaning agent through the inside of the pipe. S7: After cleaning, turn off the ultrasonic cleaner. The user restarts the mobile machine and controls it to move upward along the track, so that the lifting plate moves from the preset position H3 to the preset position H2. The No. 4 air hood extends, and the gas in the No. 2 air cylinder flows into the No. 4 air hood through the flow pipe. Under the action of the reset spring, the No. 2 plunger moves down, controlling the air nozzle to move from the preset position M2 to the preset position M1. S8: When the nozzle and one end of the pipe are on the same horizontal line, i.e., at the preset position M1, the second tension sensor detects that the tension value of the second tension spring reaches F2 and sends a signal to the control unit of the second motor. The second motor drives the screw to rotate, controlling the slide to move away from the bottom of the side beam. The end of the slide extends out of the cleaning tank of the ultrasonic cleaner. At the same time, the first tension sensor detects the change in the tension value signal of the first tension spring and sends a signal to the control units of the first exhaust valve, the first air supply valve, the second exhaust valve, and the second air supply valve, causing the first exhaust valve to open, the first air supply valve to close, the second exhaust valve to close, and the second air supply valve to open. This allows the gas in the third air hood to flow into the nozzle through the second air supply pipe. The gas is discharged through the nozzle and blown into the inside of the pipe, causing the cleaning agent remaining in the pipe to be discharged from the other end. The discharged cleaning agent falls into the slide and slides out along the slide.

[0016] The beneficial effects of this invention are: 1. By driving the pipe fixed by the bracket assembly to swing back and forth in the cleaning agent of the ultrasonic cleaner, the inside of the pipe is fully contacted with the cleaning agent, which can effectively avoid the formation of air bubble retention areas inside the pipe during the cleaning process and improve the cleaning effect. 2. The vortex component installed at the end of the pipe fitting with a larger opening can accelerate the flow rate of the cleaning agent inside and around the pipe fitting while cleaning, increasing the amount of cleaning agent passing through per unit time, ensuring full contact between the cleaning agent and the pipe fitting, and further improving the cleaning effect. 3. By cooperating with the No. 1 air supply component and the No. 1 transmission component, the power generated by the swing of the bracket component is used as the power for the operation of the vortex component. This mechanical transmission method is relatively stable and not prone to failure. 4. By setting up the No. 2 air supply component and the air nozzle, airflow is introduced into the pipe before it enters the cleaning agent, which promotes the discharge of residual waste residue inside and reduces unnecessary waste and pollution of the cleaning agent. 5. By setting up the No. 3 air supply component and the air nozzle, after the pipe is cleaned and the cleaning agent is lifted out, air flow can be introduced into the pipe to make the residual cleaning agent inside fling out, which is beneficial to the subsequent drying treatment of the pipe. 6. Through the cooperation of the second transmission component and the chute, the waste residue blown out of the pipe fitting is received and discharged to the outside of the ultrasonic cleaner through the inclined structure of the chute, so as to avoid the waste residue falling into the cleaning agent and causing unnecessary pollution. 7. By coordinating the hoisting assembly and the No. 3 air supply assembly, during the process of sending the pipe into the cleaning agent, the air nozzle should be raised in a timely manner to avoid the possibility of the cleaning agent entering and to prevent water from entering the air nozzle, which would affect the blowing effect.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-12This invention provides an embodiment of an automated pipe cleaning device, comprising an ultrasonic cleaner 1, a frame 2 mounted on the ultrasonic cleaner 1, a lifting assembly mounted on the frame 2, a platform assembly mounted on the lifting assembly, a primary motor 404 mounted on the platform assembly, and a bracket assembly mounted on the output end of the primary motor 404. The lifting assembly drives the platform assembly to move vertically, and the primary motor 404 drives the bracket assembly to rotate at a preset angle. A primary air supply assembly is mounted on the platform assembly, and a vortex assembly and a primary transmission assembly are mounted on the bracket assembly. When the bracket assembly rotates... At this time, gas flows between the first air supply component and the first transmission component. The input end of the vortex component is connected to the output end of the first transmission component. The first transmission component drives the vortex component to rotate, and the vortex component accelerates the flow rate of the cleaning agent. A lifting component is installed on the bracket assembly, and a nozzle 904 is installed on the lifting component. The second air supply component is installed on the ultrasonic cleaner 1. When the lifting component drives the platform assembly to move vertically, gas flows between the nozzle 904 and the second air supply component, installing the gas spring fitting (it is worth noting that one end of the gas spring fitting has a larger opening, and the other end has a smaller opening) on ​​the platform. Mounted on the bracket assembly, the lifting assembly is activated, and the control platform assembly and bracket assembly move the fixed pipe downwards towards the cleaning tank (containing cleaning agent) of the ultrasonic cleaner 1. During the movement, the second air supply assembly inputs gas into the nozzle 904, which blows the gas into one end of the pipe (in this technical solution, the small opening end of the gas spring pipe) to blow out any remaining residue. After the pipe enters the cleaning agent, the first motor 404 outputs power to the bracket assembly, controlling the bracket assembly and the fixed pipe to swing back and forth in two directions (the swing amplitude is designed according to needs). During the swinging process, the bracket assembly drives the first air supply assembly to input the gas inside it into the first transmission assembly, causing the first transmission assembly to output power to the vortex assembly. The high-speed rotation of the vortex assembly accelerates the flow rate of the cleaning agent inside and around the pipe, improving the cleaning effect of the cleaning agent on the pipe. After cleaning, the lifting assembly controls the platform assembly and the bracket assembly to move the fixed pipe upward and away from the cleaning tank of the ultrasonic cleaner 1. During the movement, the second air supply assembly inputs gas into the nozzle 904 again. The nozzle 904 blows the gas out from one end of the pipe, expelling the residual cleaning agent in the pipe.

[0021] Please see Figures 1-9In this embodiment, the lifting assembly includes a track 301 mounted on the ultrasonic cleaner 1, a moving machine 302 slidably mounted on the track 301, a guide rod 304 fixedly mounted on the frame 2, a first tension spring 305 connected at one end to the frame 2, and a first tension sensor 306 mounted on the first tension spring 305. The moving machine 302 moves vertically along the track 301, and the first tension spring 305 is sleeved on the guide rod 304. The platform assembly is movably connected to the guide rod 304. The platform assembly includes a lifting plate 303 fixedly mounted on the moving machine 302, a hanger 401 fixedly connected to the lifting plate 303, a balance beam 402 fixedly connected to the hanger 401, and two base plates 403 fixedly mounted on the balance beam 402. The first tension sensor 306 is mounted on the lifting plate 303 and is used to detect the tension value of the first tension spring 305 and generate... The control unit of motor 404 sends a signal to the first motor 404. The output end of motor 404 is located between the two base plates 403. Motor 404 is mounted on the balance beam 402. Air delivery component 404 is mounted on the base plate 403. As the moving machine 302 (specifically a linear motor in this solution, but in actual applications it can also be a screw motor 1202, cylinder, or hydraulic cylinder, etc., directly outputting power to control the platform component to move vertically) moves up and down along the track 301, it drives the lifting plate 303, the hanger 401, the balance beam 402, and the base plate 403 fixed thereto to move synchronously. During the movement, it pulls the first tension spring 305. After the first tension sensor 306 detects the tension value of the first tension spring 305, it sends a signal to the second air delivery component and motor 404. The second air delivery component delivers gas to the nozzle 904 and controls motor 404 to run at the appropriate time.

[0022] Please see Figures 1-5 and Figures 8-9In this embodiment, the bracket assembly includes a support beam 501 fixedly connected to the output end of a primary motor 404, a bracket 502 fixedly mounted on the support beam 501, a side beam 503 fixedly connected to the bracket 502, a retaining ring 504 fixedly mounted on the side beam 503, a buckle beam 505 movably connected to the bracket 502, a buckle ring 506 fixedly mounted on the buckle beam 505, a return torsion spring 507 mounted on the buckle beam 505, a side platform 508 fixedly mounted on one side of the side beam 503, and a side support rod 509 fixedly mounted on the other side of the side beam 503. The primary motor 404 is used to drive... The support beam 501 flips at a preset angle. One end of the reset torsion spring 507 is connected to the bracket 502, and the other end is connected to the buckle beam 505. The retaining ring 504 and the buckle ring 506 are adapted to the outer diameter of the pipe fitting. The support beam 501 is set above the base plate 403. The first air supply assembly includes a first air hood 601 installed on the corresponding base plate 403, a first air supply pipe 602 fixedly connected to one of the air hoods at one end, and a second air supply pipe 603 connected to the other first air hood 601 at one end. The other ends of the first air supply pipe 602 and the second air supply pipe 603 are both connected to the first transmission assembly. The upper end of the No. 1 air hood 601 is connected to the support beam 501. When the support beam 501 flips at a preset angle, gas flows between the No. 1 air supply pipe 602 or the No. 2 air supply pipe 603 and the No. 1 air hood 601 and the No. 1 transmission assembly. When fixing the pipes, it is necessary to first overcome the elastic force of the return torsion spring 507, flip the buckle beam 505 upward and open it, fix an appropriate number of pipes to the side beam 503 through the retaining ring 504, and then release the buckle beam 505. Under the action of the return torsion spring 507, the buckle beam 505 flips downward and presses the fixed pipes through the retaining ring 506. (It is worth noting that in this solution, the pipes...) (The small opening end faces the nozzle 904, and the large opening end faces the vortex assembly). After the moving machine 302 lowers the pipe into the cleaning agent, the first motor 404 starts and outputs power to the support beam 501, controlling the support beam 501 to swing back and forth (it is worth noting that in this scheme, it swings towards the two base plates 403 respectively). When swinging to one side, the support beam 501 will squeeze the first air hood 601 on that side. When swinging to the other side, the support beam 501 will squeeze the first air hood 601 on the other side. The gas in the two air hoods is successively input into the first transmission assembly through the first air supply pipe 602 and the second air supply pipe 603.

[0023] Please see Figures 1-6 and Figure 10In this embodiment, the vortex assembly includes a plurality of turbine blades 701 movably connected to the side platform 508, transmission gears 702 fixedly connected to the corresponding turbine blades 701, a gear chain 703 meshing with the plurality of transmission gears 702, and a driven gear 704 fixedly connected to one of the transmission gears 702. The driven gear 704 is connected to the output end of the first transmission assembly. The driven gear 704 is used to drive the transmission gears 702 and the gear chain 703 to continuously transmit power. The transmission gears 702 are used to drive the turbine blades 701 to rotate. The turbine blades 701 are used to accelerate the cleaning agent. The flow rate; the first transmission assembly includes a first air cylinder 801 mounted on the side platform 508, a first plunger 802 movably connected inside the first air cylinder 801, a rocker arm 803 movably connected at one end to the first plunger 802, and a linkage gear 804 movably connected to the side platform 508. The other end of the rocker arm 803 is movably connected to the eccentric position of the linkage gear 804. The linkage gear 804 meshes with the driven gear 704. A first air supply pipe 602 is connected to one end of the first air cylinder 801, and a second air supply pipe 603 is connected to the other end of the first air cylinder 801. The first air hood 601 contains... Gas flows into cylinder 801 through either gas supply pipe 602 or gas supply pipe 603. Piston 802 drives rocker arm 803 to swing. Rocker arm 803 drives driven gear 704 to rotate via linkage gear 804. Gas supply pipes 602 and 603 sequentially deliver gas into cylinder 801 (note that gas supply pipes 602 and 603 deliver gas in opposite directions). This controls piston 802 to move in opposite directions, thereby controlling piston 802 to pull rocker arm 803 to swing in both directions. The linkage gear 804 is driven to rotate in two directions. When the linkage gear 804 rotates in one direction, it drives the transmission gear 702 and the transmission chain to rotate continuously through meshing with the driven gear 704, controlling the turbine fan blade 701 to rotate at high speed. Similarly, when the linkage gear 804 rotates in the other direction, the turbine fan blade 701 also rotates at high speed in the opposite direction, causing the cleaning agent to flow faster (because the openings at both ends of the gas spring tube are not the same size, the cleaning agent flows unevenly, the cleaning fluid flows slowly inside the tube, and the cleaning effect is not good, so it is necessary to increase the flow speed of the cleaning agent to improve the cleaning effect).

[0024] Please see Figures 1-7 and Figures 11-12In this embodiment, the second air supply assembly includes a second air hood 1001 installed on the ultrasonic cleaner 1, a first exhaust pipe 1002 fixedly connected to the second air hood 1001, a first exhaust valve 1003 installed on the first exhaust pipe 1002, a first air supply pipe 1004 fixedly connected to the second air hood 1001 at one end, a first air supply valve 1005 installed on the first air supply pipe 1004, a third air hood 1006 installed on the ultrasonic cleaner 1, a second exhaust pipe 1007 fixedly connected to the third air hood 1006, a second exhaust valve 1008 installed on the second exhaust pipe 1007, a second air supply pipe 1009 fixedly connected to the third air hood 1006 at one end, and a second air supply pipe 1009 installed on the second air supply pipe 10001. The second air supply valve 1010 on the 9th floor and the second air hood 1001 are located below the lifting plate 303, while the third air hood 1006 is located above the lifting plate 303. The first tension sensor 306 is used to send signals to the control units of the first exhaust valve 1003, the first air supply valve 1005, the second exhaust valve 1008, and the second air supply valve 1010. When the lifting plate 303 moves downward, the first exhaust valve 1003 closes, the first air supply valve 1005 opens, the second exhaust valve 1008 opens, and the second air supply valve 1010 closes. Gas in the second air hood 1001 flows into the nozzle 904 through the first air supply pipe 1004. When the lifting plate 303 moves upward, the first exhaust valve 1003 opens, the first air supply valve 1005 closes, and the second air supply valve 1010 closes. Exhaust valve 1008 is closed, and second air supply valve 1010 is open. Gas in third air hood 1006 flows into nozzle 904 through second air supply pipe 1009. Exhaust valve 1003, first air supply valve 1005, exhaust valve 1008, and second air supply valve 1010 are all electric valves, controlled by signals sent by first tension sensor 306. When the moving machine 302 controls the pipe to move downward (from preset position H1 to preset position H2, preset position H2 to preset position H3), exhaust valve 1003 and second air supply valve 1010 are both closed, and air supply valve 1005 and second exhaust valve 1008 are both open. Lifting plate 303 compresses second air hood 1001, causing gas in second air hood 1001 to flow into the nozzle 904. Gas flows into nozzle 904 through the first gas supply pipe 1004, and then is blown out through the hole on nozzle 904 into the pipe fitting, blowing out the waste residue in the pipe fitting. When the moving machine 302 controls the pipe fitting to move upward (from preset position H3 to preset position H2, preset position H2 to preset position H1, that is, pulling the pipe fitting upward from the cleaning agent), the first exhaust valve 1003 and the second gas supply valve 1010 are both in the open state, and the first gas supply valve 1005 and the second exhaust valve 1008 are both in the closed state. The lifting plate 303 compresses the third air hood 1006, causing the gas in the third air hood 1006 to flow into nozzle 904 through the second gas supply pipe 1009, and then is blown out through the hole on nozzle 904 into the pipe fitting, blowing out the residual cleaning agent in the pipe fitting.

[0025] Please see Figures 1-6 and Figures 11-12In this embodiment, the ultrasonic cleaner 1 is equipped with a third air supply assembly. When the lifting assembly drives the platform assembly to move vertically, gas flows between the hoisting assembly and the third air supply assembly. The hoisting assembly drives the nozzle 904 to move vertically. When the platform assembly moves between preset positions H1 and H2, the nozzle 904 and the end of the pipe are on the same horizontal plane. When the platform assembly moves from preset position H2 to preset position H3, the hoisting assembly drives the nozzle 904 to move upward. When the platform assembly moves from preset position H3 to preset position H2, the hoisting assembly drives the nozzle 904 to move downward. A second transmission assembly is installed on the bracket assembly. The second transmission assembly drives the slide 13 horizontally. The lifting assembly includes a second air cylinder 901 mounted on the side support rod 509, a second plunger 902 movably connected in the second air cylinder 901, and a return spring 903 installed in the second air cylinder 901. An air nozzle 904 is mounted on the second plunger 902. One end of the return spring 903 is connected to the second air cylinder 901, and the other end is connected to the second plunger 902. When the lifting plate 303 moves from the preset position H2 to the preset position H3, the lifting assembly drives the air nozzle 904 to move from the preset position M1 to the preset position M2. When the lifting plate 303 moves from the preset position H3 to the preset position H2, the lifting assembly drives the air nozzle 904 to move from the preset position M2 to the preset position M1. The third air supply assembly includes components fixedly mounted on the frame 2. The system includes a slide bar 1101 and a slide plate 1102 movably connected to the slide bar 1101; a fourth air hood 1103 mounted on the slide plate 1102 and a flow pipe 1104 connected at one end to the fourth air hood 1103, with the other end of the flow pipe 1104 connected to the second air cylinder 901; when the lifting plate 303 moves from the preset position H2 to the preset position H3, the gas in the fourth air hood 1103 flows into the second air cylinder 901 through the flow pipe 1104; when the lifting plate 303 moves from the preset position H3 to the preset position H2, the gas in the second air cylinder 901 flows into the fourth air hood 1103 through the flow pipe 1104; the second transmission assembly includes a second motor 1201 mounted on the side support rod 509 and a component fixedly connected to the second motor 1201. The output end of 201 has a screw 1202, a second tension sensor 1204 mounted on the side support rod 509, and a second tension spring 1203 connected at one end to the second tension sensor 1204. The other end of the second tension spring 1203 is connected to the nozzle 904. The second tension sensor 1204 is used to detect the tension value of the second tension spring 1203 and send a signal to the second motor 1201. The second motor 1201 is used to drive the screw 1202 to rotate. The slide groove 13 is threadedly connected to the screw 1202. The screw 1202 is used to drive the slide groove 13 to move. When the second tension sensor 1204 detects that the tension value of the second tension spring 1203 reaches F1, the motor drives the slide groove 13 to move closer to the bottom of the side beam 503 through the screw 1202.When the tension sensor 1204 detects that the tension value of the tension spring 1203 reaches F2, the motor drives the slide 13 away from the side beam 503 via the screw 1202. As the moving machine 302 moves the pipe downwards (it is worth noting that during the downward movement of the pipe, the air supply component 3 is in two states: when the lifting plate 303 moves from the preset position H1 to the preset position H2, the air hood 1103 is not compressed by the lifting plate 303; when it moves from the preset position H2 to the preset position H3, the air hood 1103 is compressed by the lifting plate 303), the air supply component 303 is compressed by the lifting plate 303. 03. Compression: Gas in No. 4 air hood 1103 flows through flow pipe 1104 into No. 2 air cylinder 901. The pipe gradually approaches the cleaning agent until it is submerged. The gas entering No. 2 air cylinder 901 pushes No. 2 plunger 902 to move, pulling nozzle 904 from preset position M1 to preset position M2. (It is worth noting that when the lifting plate 303 moves from preset position H1 to preset position H2, the nozzle 904 and the open end of the pipe are at the same horizontal plane, i.e., preset position M1. When the lifting plate 303 moves from...) When the nozzle 904 moves from preset position H2 to preset position H3, it immediately moves. At this time, the nozzle 904 is not in contact with the cleaning agent. This ensures that the nozzle 904 does not come into contact with the cleaning agent during the entire movement process, preventing water from entering the nozzle 904. During the movement of the nozzle 904, the second tension sensor 1204 detects the tension value of the second tension spring 1203 and sends a signal to the second motor 1201. The second motor 1201 controls the screw 1202 to rotate, and through the threaded transmission, controls the movement of the slide 13 (in practical applications, the slide 13...). A guide can also be installed between the lifting plate 303 and the side beam 503 to stabilize the movement direction of the slide 13. When the lifting plate 303 moves between the preset position H1 and the preset position H2, the slide 13 is positioned away from the side beam 503. At this time, the waste residue and cleaning agent discharged from the pipe will fall into the slide 13 and be discharged outside the ultrasonic cleaner 1. When the lifting plate 303 moves between the preset position H2 and the preset position H3, the slide 13 is positioned close to the side beam 503 to prevent interference with the ultrasonic cleaner 1.

[0026] Please see Figures 1-12 In this embodiment, the present invention provides an automated pipe cleaning method, employing an automated pipe cleaning device as described above, comprising the following steps: S1: The user first flips the buckle beam 505 upwards to open it, and fixes an appropriate number of pipe fittings to the side beam 503 through the retaining ring 504 (the retaining ring 504 is made of tough material, semi-circular arc shape, and the pipe fittings are squeezed into the retaining ring 504). Then, the user releases the buckle beam 505. Under the action of the return torsion spring 507, the buckle beam 505 flips downwards and presses and fixes the pipe fittings through the retaining ring 506 (made of the same material as the retaining ring 504, arc structure). S2: Start the mobile unit 302 and control it to move downwards along the track 301, causing the lifting plate 303 to move from the preset position H1 to the preset position H2, and gradually bringing the pipe closer to the cleaning tank of the ultrasonic cleaner 1. The first tension sensor 306 detects the change in the tension value signal of the first tension spring 305 and sends a signal to the control unit of the first exhaust valve 1003, the first air supply valve 1005, the second exhaust valve 1008, and the second air supply valve 1010 (all of the above valves are electric valves), causing the first exhaust valve 1003 to close, the first air supply valve 1005 to open, and the second exhaust valve 1008 to open. When the second air valve 1010 is closed, the gas in the second air hood 1001 flows into the nozzle 904 through the first air pipe 1004. At this time, the nozzle 904 and one end of the pipe are on the same horizontal line, i.e., at the preset position M1. The gas is discharged through the nozzle 904 and blown into the inside of the pipe, causing the residue in the pipe to be discharged from the other end. At this time, the chute 13 is located below the side beam 503 and the end of the chute 13 extends outside the cleaning tank of the ultrasonic cleaner 1. The discharged residue falls into the chute 13 and slides out along the chute 13 (one end of the chute 13 extends outside the ultrasonic cleaner 1). S3: When the mobile unit 302 moves further down along the track 301, the lifting plate 303 moves from the preset position H2 to the preset position H3. The lifting plate 303 abuts against and presses against the slide plate 1102, compressing the fourth air hood 1103. Through the flow pipe 1104, the gas in the fourth air hood 1103 flows into the second air cylinder 901, causing the second plunger 902 to move upward, pulling the air nozzle 904 from the preset position M1 to the preset position M2, away from the cleaning agent in the ultrasonic cleaner 1. During the process, the second tension sensor 1204 detects that the tension value of the second tension spring 1203 reaches F1, and sends a signal to the control unit of the second motor 1201. The second motor 1201 drives the screw 1202 to rotate, controlling the slide 13 to move closer to the bottom of the side beam 503 (retracting into the cleaning tank of the ultrasonic cleaner 1). S4: When the lifting plate 303 moves to the preset position H3, the pipe is completely immersed in the cleaning agent. At this time, the nozzle 904 also enters the preset position M2. The first tension sensor 306 detects the change in the tension value signal of the first tension spring 305 and sends a signal to the control unit of the first motor 404. S5: Motor 404 outputs power to support beam 501, controlling support beam 501 to swing back and forth in the opposite direction, causing the pipe fixed by snap ring 504 and buckle 506 to swing in the cleaning agent. At the same time, ultrasonic cleaner 1 starts, using the cavitation effect generated by ultrasonic waves in the cleaning agent to clean the surface and internal dirt of the pipe. S6: As the support beam 501 swings back and forth, it will squeeze the corresponding No. 1 air hood 601. The gas in the No. 1 air hood 601 is introduced into the No. 1 air cylinder 801 through the No. 1 air supply pipe 602 or the No. 2 air supply pipe 603. The gas flowing out of the No. 1 air supply pipe 602 and the No. 2 air supply pipe 603 flows into the No. 1 air cylinder 801 in sequence from two directions, causing the No. 1 plunger 802 to move back and forth in the No. 1 air cylinder 801. This controls the rocker arm 803 to swing in two directions in sequence. The rocker arm 803 controls the linkage gear 804 to rotate. Through the meshing of the linkage gear 804 and the driven gear 704, the transmission gear 702 and the gear chain 703 are driven to run continuously, driving the turbine fan blade 701 to rotate at high speed, rolling up the cleaning agent and accelerating the flow of the cleaning agent through the inside of the pipe. S7: After cleaning, turn off the ultrasonic cleaner 1. The user restarts the mobile machine 302 and controls it to move upward along the track 301, so that the lifting plate 303 moves from the preset position H3 to the preset position H2. The fourth air hood 1103 extends. The gas in the second air cylinder 901 flows into the fourth air hood 1103 through the flow pipe 1104. Under the action of the reset spring 903, the second plunger 902 moves downward, controlling the air nozzle 904 to move from the preset position M2 to the preset position M1. S8: When the nozzle 904 and one end of the pipe are on the same horizontal line, i.e., at the preset position M1, the second tension sensor 1204 detects that the tension value of the second tension spring 1203 has reached F2, and sends a signal to the control unit of the second motor 1201. The second motor 1201 drives the screw 1202 to rotate, controlling the slide 13 to move away from the bottom of the side beam 503. The end of the slide 13 extends outside the cleaning tank of the ultrasonic cleaner 1. At the same time, the first tension sensor 306 detects the change in the tension value signal of the first tension spring 305 and sends a signal to... The control unit of exhaust valve 1003, gas supply valve 1005, exhaust valve 1008, and gas supply valve 1010 causes exhaust valve 1003 to open, gas supply valve 1005 to close, exhaust valve 1008 to close, and gas supply valve 1010 to open. This allows gas in air hood 1006 to flow into nozzle 904 through gas supply pipe 1009. The gas is then discharged through nozzle 904 and blown into the interior of the pipe fitting, causing residual cleaning agent in the pipe fitting to be discharged from the other end. The discharged cleaning agent falls into chute 13 and slides out along chute 13.

When the second tension sensor (1204) detects that the tension value of the second tension spring (1203) reaches F1, the motor drives the slide (13) to move closer to the side beam (503) via the screw (1202); when the second tension sensor (1204) detects that the tension value of the second tension spring (1203) reaches F2, the motor drives the slide (13) away from the side beam (503) via the screw (1202).

10. An automated cleaning method for pipe fittings, characterized in that: The automated pipe cleaning device as described in claim 9 includes the following steps: S1: The user first flips the buckle beam (505) upward to open it, fixes an appropriate number of pipe fittings on the side beam (503) through the snap ring (504), and then loosens the buckle beam (505). Under the action of the reset torsion spring (507), the buckle beam (505) flips downward and presses the fixed pipe fittings through the snap ring (506). S2: Start the mobile machine (302) and control it to move downward along the track (301), so that the lifting plate (303) moves from the preset position H1 to the preset position H2, and drives the pipe to gradually approach the cleaning tank of the ultrasonic cleaner (1). The first tension sensor (306) detects the change in the tension value signal of the first tension spring (305) and sends a signal to the control unit of the first exhaust valve (1003), the first air supply valve (1005), the second exhaust valve (1008), and the second air supply valve (1010), so that the first exhaust valve (1003) closes, the first air supply valve (1005) opens, and the second exhaust valve (1008) opens. 8) Open, the second gas valve (1010) is closed, so that the gas in the second gas hood (1001) flows into the nozzle (904) through the first gas pipe (1004). At this time, the nozzle (904) and one end of the pipe are on the same horizontal line, that is, at the preset position M1. The gas is discharged through the nozzle (904) and blown into the inside of the pipe, so that the residue in the pipe is discharged from the other end. At this time, the chute (13) is located far below the side beam (503). The end of the chute (13) extends to the outside of the cleaning tank of the ultrasonic cleaner (1). The discharged residue falls into the chute (13) and slides out along the chute (13). S3: When the mobile machine (302) moves further down along the track (301), the lifting plate (303) moves from the preset position H2 to the preset position H3. The lifting plate (303) abuts against and presses against the slide plate (1102), causing the No. 4 air hood (1103) to be compressed. Through the flow pipe (1104), the gas in the No. 4 air hood (1103) flows into the No. 2 air cylinder (901), causing the No. 2 plunger (902) to move upward, pulling the air nozzle (904) from the preset position M1 to the preset position M2, away from the cleaning agent in the ultrasonic cleaner (1). During the process, the No. 2 tension sensor (1204) detects that the tension value of the No. 2 tension spring (1203) reaches F1, and sends a signal to the control unit of the No. 2 motor (1201). The No. 2 motor (1201) drives the screw (1202) to rotate, controlling the slide (13) to approach the bottom of the side beam (503). S4: When the lifting plate (303) moves to the preset position H3, the pipe is completely immersed in the cleaning agent. At this time, the nozzle (904) also enters the preset position M2. The first tension sensor (306) detects the change in the tension value signal of the first tension spring (305) and sends a signal to the control unit of the first motor (404). S5: The No. 1 motor (404) outputs power to the support beam (501), controlling the support beam (501) to swing back and forth in the opposite direction, so that the pipe fixed by the retaining ring (504) and the buckle (506) swings in the cleaning agent. At the same time, the ultrasonic cleaner (1) starts, using the cavitation effect generated by the ultrasonic waves in the cleaning agent to clean the surface and internal dirt of the pipe. S6: While the support beam (501) swings back and forth, it will squeeze the corresponding No. 1 air hood (601). The gas in the No. 1 air hood (601) is introduced into the No. 1 air cylinder (801) through the No. 1 air supply pipe (602) or the No. 2 air supply pipe (603). The gas flowing out of the No. 1 air supply pipe (602) and the No. 2 air supply pipe (603) flows into the No. 1 air cylinder (801) in sequence from two directions, causing the No. 1 plunger (802) to move back and forth in the No. 1 air cylinder (801). The rocker arm (803) swings in sequence in two directions. The rocker arm (803) controls the linkage gear (804) to rotate. Through the meshing of the linkage gear (804) and the driven gear (704), the transmission gear (702) and the gear chain (703) are driven to run continuously, driving the turbine fan blade (701) to rotate at high speed, rolling the cleaning agent and accelerating the flow of the cleaning agent through the inside of the pipe. S7: After cleaning, turn off the ultrasonic cleaner (1), and the user restarts the mobile machine (302) and controls it to move upward along the track (301), so that the lifting plate (303) moves from the preset position H3 to the preset position H2, the No. 4 air hood (1103) extends, and the gas in the No. 2 air cylinder (901) flows into the No. 4 air hood (1103) through the flow pipe (1104). Under the action of the reset spring (903), the No. 2 plunger (902) moves downward, and the control nozzle (904) moves from the preset position M2 to the preset position M1. S8: When the nozzle (904) and one end of the pipe are on the same horizontal line, i.e., at the preset position M1, the second tension sensor (1204) detects that the tension value of the second tension spring (1203) reaches F2, and sends a signal to the control unit of the second motor (1201). The second motor (1201) drives the screw (1202) to rotate, controlling the slide (13) to move away from the bottom of the side beam (503). The end of the slide (13) extends outside the cleaning tank of the ultrasonic cleaner (1). At the same time, the first tension sensor (306) detects the change in the tension value signal of the first tension spring (305) and sends a signal to the first tension spring (1203). The control unit of the exhaust valve (1003), the first gas supply valve (1005), the second exhaust valve (1008), and the second gas supply valve (1010) causes the first exhaust valve (1003) to open, the first gas supply valve (1005) to close, the second exhaust valve (1008) to close, and the second gas supply valve (1010) to open, so that the gas in the third gas hood (1006) flows into the nozzle (904) through the second gas supply pipe (1009), and the gas is discharged through the nozzle (904) and blown into the inside of the pipe fitting, so that the cleaning agent remaining in the pipe fitting is discharged from the other end. The discharged cleaning agent falls into the chute (13) and slides out along the chute (13).
