[0027] like Figures 1 to 5 As shown, an automatic cleaning device for a central air-conditioning condenser pipe comprises a base 1 and a condenser pipe, wherein a cleaning mechanism 3 which can be disassembled to clean the scale inside the condenser pipe is installed on the outer surface of the base 1, a groove is provided on the upper surface of the base 1, a supporting mechanism 2 is installed inside the groove of the base 1, a driving mechanism 4 is provided on the upper surface of the base 1, and a stirring mechanism 6 is installed on the back of the cleaning mechanism 3; specifically, the cleaning mechanism 3 is started to drive the cleaning water flow and the cleaning balls to move inside the condenser pipe, so that when the subsequent cleaning water flow flows to the inside of the condenser pipe, multiple groups of cleaning balls are pushed to clean the scale accumulated inside the condenser pipe, The cleaning water flow and multiple groups of cleaning balls are then screened and discharged through the inside of the cleaning mechanism 3, so that the subsequent cleaning mechanism 3 can discharge the multiple groups of cleaning balls out of the inside of the cleaning mechanism 3 during use, thereby facilitating the subsequent staff to regularly replace the cleaning balls accumulated inside the cleaning mechanism 3, thereby improving the cleaning efficiency of the subsequent cleaning mechanism 3 during use; a water circulation system is formed by connecting the cleaning mechanism 3 and the condenser, so that the cleaning water used by the cleaning mechanism 3 during use can be reused, thereby reducing the water resources consumed by the subsequent cleaning mechanism 3 during use, thereby improving the practicability of the device.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, the cleaning mechanism 3 includes a water pump 301, a screening box 306 and a water storage tank 310. The water storage tank 310 is installed on the lower surface of the base 1. The water pump 301 and the screening box 306 are both installed on the upper surface of the base 1. The water inlet end of the water pump 301 is installed with a water pipe 302. The water inlet end of the water pipe 302 is installed inside the drainage hole of the water storage tank 310. The drainage end of the water pump 301 is installed with a drainage pipe 303. The top upper surface of the drainage pipe 303 is provided with a feed hole. The feed hole of the drainage pipe 303 is installed with a connecting pipe 304. The condenser is placed on the upper surface of the base 1. The drainage pipe The drainage end of the first drain pipe 303 is installed inside the water inlet end of the condenser tube, the water inlet end of the screening box 306 is installed with a water guide pipe 305, the water inlet end of the water guide pipe 305 is installed at the drainage end of the condenser tube, the drainage end of the water guide pipe 305 is installed with an annular filter screen 311, the position of the annular filter screen 311 is set inside the screening box 306, the drainage end of the screening box 306 is installed with a second drain pipe 307, the drainage end of the second drain pipe 307 is installed inside the water inlet hole of the water storage tank 310, the drainage end of the annular filter screen 311 is installed with a guide pipe 308, and the outer surface of the guide pipe 308 is provided with a valve 309;

[0029] Specifically, after multiple groups of cleaning balls are added to the interior of the connecting pipe 304, the water pump 301 is started to transport the cleaning water flow along the water supply pipe 302 and the drain pipe 303 to the interior of the condenser, so that the subsequent cleaning water flow pushes the multiple groups of cleaning balls that fall into the drain pipe 303 due to gravity inside the connecting pipe 304 when it floats to the interior of the drain pipe 303, and then the subsequent cleaning water flow pushes the multiple groups of cleaning balls to clean the scale accumulated inside the condenser when it flows to the interior of the condenser, and then the water inlet end of the water guide pipe 305 is connected to the drain end of the condenser, so that the subsequent clean water flow and multiple groups of cleaning balls accumulated in the condenser are discharged into the screen along the water guide pipe 305. The interior of the separation box 306 is completed to automatically clean the scale inside the condenser; the clean water flow and cleaning balls discharged from the water pipe 305 into the screening box 306 are filtered through the annular filter screen 311, so that the annular filter screen 311 screens the cleaning balls and the clean water flow, and then by rotating the valve 309, multiple groups of cleaning balls accumulated in the annular filter screen 311 are guided out along the guide pipe 308, so that the subsequent cleaning mechanism 3 can guide the multiple groups of cleaning balls out of the interior of the cleaning mechanism 3 during use, so that the subsequent staff can regularly replace the cleaning balls accumulated in the cleaning mechanism 3, thereby improving the cleaning efficiency of the subsequent cleaning mechanism 3 during use.

[0030] At the same time, the water inlet end of the water supply pipe 302 is connected to the drainage hole of the water tank 310, and the clean water accumulated in the screening box 306 is introduced into the water tank 310 through the drainage pipe 307, so that the water flow after use of the cleaning mechanism 3 is discharged into the water tank 310, and the clean water used by the cleaning mechanism 3 during use can be recycled, thereby minimizing the water resources consumed by the subsequent cleaning mechanism 3 during use, thereby improving the practicality of the device.

[0031] like Figure 1 and Figure 2 As shown, the driving mechanism 4 includes a bellows 401, an air compressor 403 and a hydraulic cylinder 405. The air compressor 403 is installed on the upper surface of the base 1. The air suction end of the air compressor 403 is installed with an air suction pipe 404. The bellows 401 is installed on the guide end of the guide pipe 308. The guide end of the bellows 401 is provided with a fixed pipe 402. The hydraulic cylinder 405 is installed on the upper surface of the screening box 306. The output end of the hydraulic cylinder 405 is installed with a U-shaped bracket 406. The inner wall of the U-shaped bracket 406 is clamped on the outer surface of the fixed pipe 402. The fixed pipe 402 is provided with an air inlet hole on one side close to the water pump 301. The air suction end of the air suction pipe 404 is installed inside the air inlet hole of the fixed pipe 402. The guide end of the fixed pipe 402 is clamped on the outer surface of the feed end of the connecting pipe 304.

[0032] Specifically, when the subsequent staff uses the cleaning balls inside the annular filter 311 to clean the inside of another group of condenser tubes again, the cleaning balls accumulated inside the annular filter 311 are introduced into the inside of the bellows 401 along the guide pipe 308 by turning the valve 309, and then the cleaning balls accumulated inside the bellows 401 are attracted to the end of the fixed pipe 402 close to the water pump 301 by starting the air compressor 403 to generate suction. When all the multiple groups of cleaning balls inside the bellows 401 are guided to the inside of the end of the fixed pipe 402 close to the water pump 301, and the air compressor is closed, the cleaning balls are sucked out. The machine 403 allows the multiple groups of cleaning balls accumulated in the fixed tube 402 to fall into the connecting tube 304 under the action of gravity, so that subsequent staff can quickly guide the multiple groups of cleaning balls accumulated in the annular filter 311 to the inside of the connecting tube 304 without manual removal, thereby shortening the time spent by subsequent staff in resetting the multiple groups of cleaning balls in the annular filter 311, thereby shortening the labor spent by subsequent staff in using the cleaning mechanism 3 to clean the inside of another group of condensation tubes, thereby improving the practicality of the device.

[0033] At the same time, when subsequent staff need to take out multiple groups of cleaning balls accumulated inside the fixed tube 402, the U-shaped bracket 406 is pushed by starting the hydraulic cylinder 405 to drive the fixed tube 402 to move, and then the guide end of the fixed tube 402 is clamped on the outer surface of the feed end of the connecting tube 304, so that the fixed tube 402 is disconnected from the feed end of the connecting tube 304 during the subsequent upward movement, so that the subsequent staff can quickly take out the cleaning balls introduced into the fixed tube 402 without manually disassembling the mobile fixed tube 402, thereby minimizing the impact of the subsequent driving mechanism 4 on the normal replacement of the multiple groups of cleaning balls accumulated inside the cleaning mechanism 3 by the staff during use.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, the support mechanism 2 includes a support plate 201 and an electric telescopic rod 202, the electric telescopic rod 202 is installed inside the groove of the base 1, the support plate 201 is installed at the output end of the electric telescopic rod 202, the lower surface of the support plate 201 abuts against the upper surface of the base 1, and the upper surface of the support plate 201 fits against the lower surface of the condenser; specifically, when the two ends of the subsequent condenser are installed inside the cleaning mechanism 3, the support plate 201 is pushed to move by starting the electric telescopic rod 202, and the upper surface of the support plate 201 abuts against the lower surface of the condenser, so that the support plate 201 supports the condenser, thereby minimizing the internal bearing mass of the subsequent condenser during the automatic cleaning process, which causes bending at the connection between the two ends of the condenser and the cleaning mechanism 3.

[0035] like Figure 1 and Figure 2As shown, a through hole is opened on the upper surface of the water tank 310, and a guide hopper 5 is inserted into the through hole of the water tank 310; specifically, an acidic solution is added to the water tank 310 through the guide hopper 5, so that the alkaline scale subsequently introduced into the water tank 310 is neutralized by the acidic solution, thereby avoiding as much as possible that the scale accumulated in the clean water flow is introduced into the inside of another group of condensers during the reuse of the water resources in the subsequent water tank 310.

[0036] like Figures 1 to 3 As shown, the stirring mechanism 6 includes a motor 601 and two sets of gears 603. The motor 601 is installed on the back of the water tank 310. A groove is provided on the back of the water tank 310. The output shaft of the motor 601 passes through the inner groove of the water tank 310 and is installed with a gear 602. Two sets of positioning grooves are provided on the inner wall of the back of the water tank 310. The two sets of gears 603 are rotatably connected to the inside of the two sets of positioning grooves of the water tank 310 respectively. The external teeth of the two sets of gears 603 are meshed and connected to the internal teeth of the gear 602. The front faces of the two sets of gears 603 and the gear 602 are provided with fixing rods 604. The outer surfaces of the three sets of fixing rods 604 are all installed with stirring blades 605.

[0037] Specifically, the motor 601 is started to drive the gear 1 602 to trigger the two sets of gear 2 603 to rotate inside the two sets of positioning grooves of the water tank 310, and then three sets of fixing rods 604 are respectively installed on the front of the two sets of gear 2 603 and the gear 1 602, so that the subsequent staff can start the single motor 601 to drive the three sets of stirring blades 605 to stir the accumulated water inside the water tank 310, thereby shortening the dissolution time of the subsequent acidic solution added to the water tank 310, and further shortening the time spent on the dissolution of the alkaline scale inside the subsequent water tank 310, thereby improving the water delivery efficiency of the subsequent water tank 310 during use.

[0038] In summary: by starting the water pump 301 to transport the clean water flow along the water pipe 302 and the drain pipe 303 to the inside of the condenser, the subsequent clean water flow, when drifting to the inside of the drain pipe 303, pushes the multiple groups of cleaning balls that fall into the drain pipe 303 due to gravity inside the connecting pipe 304 to move, so that when the subsequent clean water flow flows to the inside of the condenser, it pushes the multiple groups of cleaning balls to clean the scale accumulated inside the condenser, and then the water inlet end of the water pipe 305 is connected to the drain end of the condenser, so that the clean water flow and the multiple groups of cleaning balls accumulated in the condenser are discharged into the condenser along the water pipe 305. The inside of the screening box 306 is cleaned automatically to clean the scale inside the condenser tube; the clean water flow and cleaning balls discharged from the water pipe 305 into the screening box 306 are filtered through the annular filter 311, so that the annular filter 311 screens the cleaning balls and the clean water flow, and then the multiple groups of cleaning balls accumulated in the annular filter 311 are led out along the guide pipe 308 by rotating the valve 309, so that the subsequent cleaning mechanism 3 can lead the multiple groups of cleaning balls out of the interior of the cleaning mechanism 3 during use, so as to facilitate the subsequent staff to regularly replace the cleaning balls accumulated in the cleaning mechanism 3.

[0039] At the same time, by turning the valve 309, the cleaning balls accumulated in the annular filter screen 311 are introduced into the interior of the bellows 401 along the guide pipe 308, and then the air compressor 403 is started to generate suction to attract the cleaning balls accumulated in the bellows 401 to the end of the fixed pipe 402 close to the water pump 301. When all the multiple groups of cleaning balls in the bellows 401 are guided to the interior of the end of the fixed pipe 402 close to the water pump 301, and the air compressor 403 is turned off, the multiple groups of cleaning balls accumulated in the fixed pipe 402 fall into the interior of the connecting pipe 304 under the action of gravity, so that subsequent staff can remove the annular filter screen 311 without manual removal. The multiple groups of cleaning balls accumulated inside the filter 311 are quickly guided to the inside of the connecting pipe 304, thereby shortening the time spent by subsequent staff in resetting the multiple groups of cleaning balls inside the multiple groups of annular filters 311; by starting the hydraulic cylinder 405 to push the U-shaped bracket 406 to drive the fixed pipe 402 to move, and then the guide end of the fixed pipe 402 is clamped on the outer surface of the feed end of the connecting pipe 304, so that the fixed pipe 402 is disconnected from the feed end of the connecting pipe 304 during the subsequent upward movement, so that the subsequent staff can quickly take out the cleaning balls introduced into the fixed pipe 402 without manually disassembling the mobile fixed pipe 402.

[0040] In addition, by starting the motor 601 to drive the gear one 602 to trigger the two sets of gear twos 603 to rotate inside the two sets of positioning grooves of the water tank 310, and then three sets of fixing rods 604 are respectively installed on the front of the two sets of gear twos 603 and gear one 602, so that subsequent staff can start the single set of motor 601 to drive the three sets of stirring blades 605 to stir the accumulated water inside the water tank 310, thereby shortening the dissolution time consumed by the subsequent acidic solution added to the water tank 310.
