Description

Technical Field

[0001] This utility model relates to the technical field of unblocking devices for municipal pipelines, specifically an unblocking device for municipal pipelines. Background Technology

[0002] Municipal pipe networks are an important part of urban infrastructure. They refer to the network system within a city that consists of various pipes, cables and their ancillary facilities used to transport and distribute various municipal public media (such as water, gas, heat, electricity, communication signals, etc.) as well as to discharge and collect sewage and rainwater. During use, drainage pipes may become obstructed due to the accumulation of debris, grease buildup, etc., which can affect their drainage function and prevent them from draining normally. Therefore, they need to be cleaned with unblocking devices to ensure the normal use of drainage pipes.

[0003] For example, a municipal pipeline maintenance device disclosed in authorization announcement number CN218264274U belongs to the technical field of municipal pipeline maintenance equipment. It includes a housing, with a geared motor fixedly installed on the inner wall of one side of the housing. A rotating shaft and an installation shaft are respectively mounted on the side of the housing, rotating upwards and downwards. Pulleys are fixedly installed on the outer surfaces of both the rotating shaft and the installation shaft. A belt is provided between the two pulleys and connected via belt drive. One end of the installation shaft is fixedly connected to the output end of the geared motor. A bushing is fixedly installed on the outer surface of the installation shaft. Several cleaning components for cleaning the inner wall of the pipeline are provided on the outer surface of the bushing. A crushing disc is fixedly installed at the other end of the installation shaft. In use, the device cleans the pipe wall through an outer cylinder, spring, inner rod, and scraper. Because the spring always maintains a pushing force on the inner rod, causing the scraper to extend outwards, it is inconvenient for the scraper to contact the inner wall of the pipeline during actual operation. Furthermore, the scraping force varies for pipes of different diameters, making it impossible to guarantee a stable cleaning effect. Utility Model Content

[0004] The purpose of this utility model is to provide a clearing device for municipal pipe networks, in order to solve the problems mentioned in the background art, such as the inconvenience of the scraper plate contacting the inner wall of the pipe during actual operation due to the adjustment of the extension length by pushing the scraper plate with an elastic element, and the inability to guarantee a stable cleaning effect due to the different scraping force for pipes of different diameters.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blockage-clearing device for municipal pipe networks, comprising a supporting base plate, a U-shaped frame fixedly connected to one end of the supporting base plate, a telescopic cylinder fixedly embedded in the middle of the top of the U-shaped frame, two fixed columns symmetrically fixedly connected inside the U-shaped frame, a lifting block slidably connected in the middle of the two fixed columns, a driven component and a cleaning component rotatably connected in the middle of the lifting block, a drive motor fixedly installed inside the U-shaped frame, a drive gear fixedly connected to the output end of the drive motor, a power supply control component fixedly installed on the side of the U-shaped frame near the supporting base plate, and a water supply component fixedly connected to the top surface of the supporting base plate. When in use, this device can adjust the cleaning height and cleaning radius according to different pipe diameters, making it suitable for cleaning different pipes and expanding its application range. Simultaneously, a bidirectional screw acts as the driving force to adjust the cleaning radius of the scraper, coordinating with water spray to clean the pipe wall, ensuring stable cleaning force and guaranteeing cleaning effectiveness.

[0006] Preferably, the four corners of the bottom of the support base plate are fixedly installed with walking wheels, and a rectangular groove is opened in the middle of the end of the support base plate away from the U-shaped frame, which makes the device easy to move. At the same time, the opening of the rectangular groove makes it easy to connect the connecting pipe.

[0007] Preferably, the driven component includes a rotating shaft rotatably connected to the middle of the lifting block. A driven gear is fixedly connected to the outer side of the rotating shaft near the U-shaped frame. The driven gear meshes with the driving gear. A rotating connector is rotatably connected to the middle of the rotating shaft near the U-shaped frame. A water supply pipe is connected to one side of the rotating connector, so that when the rotating shaft rotates, water is continuously supplied to the high-pressure nozzle through the rotating connector to rinse and clean the pipe wall after it has been cleaned by the scraper, ensuring the cleaning effect.

[0008] Preferably, the cleaning assembly includes a fixed disc, which is fixedly connected to the end of the rotating shaft away from the U-shaped frame. A bidirectional screw is fixedly connected to the side of the fixed disc. A fixed collar is fixedly connected to the middle of the rotating shaft. A receiving tube is fixedly connected to the outside of the fixed collar. A telescopic rod is movably inserted into the receiving tube. A connecting frame is fixedly connected to the end of the telescopic rod. A scraper is fixedly connected to the inside of the connecting frame by bolts. Connecting arms are rotatably connected to both ends of the connecting frame. Two sliding frames are symmetrically arranged on both sides of the fixed collar. The sliding frames and the connecting arms at both ends of the connecting frame are rotatably connected. Multiple high-pressure nozzles are fixedly connected to the outside of the rotating shaft. The bidirectional screw rotates, causing the two sliding frames to move closer or further apart, changing the angle between the connecting arms at both ends of the same connecting frame. This changes the distance between the scraper and the rotating shaft, making it suitable for cleaning pipes with different inner diameters.

[0009] Preferably, the power supply control component includes a controller, which is fixedly connected to one side of the U-shaped frame near the supporting base plate. A battery pack is fixedly connected to one corner of the U-shaped frame to control and supply power to the telescopic cylinder and the drive motor.

[0010] Preferably, the water supply component includes a water storage tank, which is fixedly installed at the top center of the support base plate. One end of the water storage tank has an installation groove, and a water supply pump is fixedly installed inside the installation groove. The water outlet of the water supply pump is connected to a water supply pipe, and a connecting pipe is connected to one end of the installation groove. Cleaning water is discharged through a high-pressure nozzle via the water supply pump and water supply pipe to flush and clean the inner wall of the pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The design incorporates a rotating shaft, driven gear, drive motor, driving gear, water supply pipe, fixed disc, double-acting screw, fixed collar, receiving pipe, telescopic rod, connecting frame, scraper, sliding frame, and connecting arm. By rotating the double-acting screw, the two sliding frames move closer or further apart, causing the angle between the connecting arms at both ends of the same connecting frame to change. This alters the distance between the scraper and the rotating shaft, allowing for adjustment based on actual conditions. Simultaneously, the telescopic cylinder controls the position and height of the lifting block, facilitating the cleaning of pipes with different inner diameters.

[0013] The design incorporates a water storage tank, connecting pipes, high-pressure nozzles, and rotating connectors. As the high-pressure nozzles rotate with the rotating shaft, they flush the inner wall of the pipe after it has been cleaned by the scraper, ensuring effective pipe cleaning.

A U-shaped frame 7 is fixedly connected to one end of the supporting base plate 1. A telescopic cylinder 8 is fixedly embedded in the middle of the top of the U-shaped frame 7. Two fixed columns 10 are symmetrically fixedly connected inside the U-shaped frame 7. A lifting block 9 is slidably connected to the middle of the two fixed columns 10. The lifting block 9 can slide on the fixed columns 10. The fixed columns 10 provide stable guidance for the lifting of the lifting block 9. A driven component and a cleaning component are rotatably connected in the middle of the lifting block 9. A drive motor 15 is fixedly installed inside the U-shaped frame 7. A drive gear 16 is fixedly connected to the output end of the drive motor 15. The drive motor 15 drives the drive gear 16 to rotate. A power supply control component is fixedly installed on the side of the U-shaped frame 7 near the supporting base plate 1. A water supply component is fixedly connected to the top surface of the supporting base plate 1.

[0021] Furthermore, each of the four corners of the bottom of the support base plate 1 is fixedly equipped with a walking wheel 2, and a rectangular groove 6 is opened in the middle of the end of the support base plate 1 away from the U-shaped frame 7.

[0022] Furthermore, the driven component includes a rotating shaft 13, with a convex plate formed at an equal angle on the outer side of the rotating shaft 13. The rotating shaft 13 is rotatably connected to the middle of the lifting block 9. A driven gear 14 is fixedly connected to the outer side of the end of the rotating shaft 13 near the U-shaped frame 7. The driven gear 14 and the driving gear 16 are meshed together. A rotating connector 12 is rotatably connected to the middle of the end of the rotating shaft 13 near the U-shaped frame 7. A water supply cavity is opened inside the end of the rotating shaft 13 near the U-shaped frame 7. The setting of the rotating connector 12 ensures a stable water supply when the rotating shaft 13 rotates. A water supply pipe 17 is connected to one side of the rotating connector 12.

[0023] Furthermore, the cleaning assembly includes a fixed disc 18, which is fixedly connected to the end of the rotating shaft 13 away from the U-shaped frame 7. A bidirectional lead screw 19 is fixedly connected to the side of the fixed disc 18. A fixed collar 20 is fixedly connected to the middle of the rotating shaft 13. A collection tube 21 is fixedly connected to the outside of the fixed collar 20. A telescopic rod 22 is movably inserted into the inside of the collection tube 21. A connecting frame 23 is fixedly connected to the end of the telescopic rod 22. A scraper 24 is fixedly connected to the inside of the connecting frame 23 by bolts. Connecting arms 26 are rotatably connected to both ends of the connecting frame 23. Two sliding frames 25 are symmetrically arranged on both sides of the fixed collar 20. The inner wall of the sliding frame 25 has a groove, which matches the convex plate to ensure that the sliding frame 25 rotates synchronously with the rotating shaft 13. The sliding frame 25 and the connecting arms 26 at both ends of the connecting frame 23 are rotatably connected. Multiple high-pressure nozzles 11 are fixedly connected to the outside of the rotating shaft 13. The high-pressure nozzles 11 rinse the pipe wall after it has been cleaned by the scraper 24, making the cleaning effect better.

[0024] Furthermore, the power supply control component includes a controller 27, which has connecting wires on its side for integrating control of the operating status of the drive motor 15, the telescopic cylinder 8, and the water pump 29. It is also connected to the battery pack 28 to supply power to the drive motor 15, the telescopic cylinder 8, and the water pump 29. The device uses a combination of battery pack 28 power supply and external power supply, which can be selected according to the actual situation. The controller 27 is fixedly connected to the side of the U-shaped frame 7 near the support base plate 1, and the battery pack 28 is fixedly connected to one corner of the U-shaped frame 7.

[0025] Furthermore, the water supply component includes a water storage tank 3, which is fixedly installed at the top center of the support base plate 1. One end of the water storage tank 3 has an installation groove 5, and a water supply pump 29 is fixedly installed inside the installation groove 5. The outlet port of the water supply pump 29 is connected to the water supply pipe 17. One end of the installation groove 5 is connected to a connecting pipe 4, which is designed to connect to an external water source to prevent the water source inside the water storage tank 3 from being insufficient to support the completion of the cleaning work.

[0026] When this application embodiment is used:

[0027] When using the device, first connect the connecting pipe 4 to the external water source. Depending on the actual situation, control the telescopic cylinder 8 to extend or retract via the controller 27, causing the lifting block 9 to slide up and down along the fixed column 10, changing the position and height of the rotating shaft 13. Then, based on the inner diameter of the pipe, rotate the double-acting screw 19. The rotation of the double-acting screw 19 and the sliding of the two sliding frames 25 along the rotating shaft 13 cause the two sliding frames 25 to move away from or closer to each other, thus changing the included angle between the connecting arms 26 at both ends of the same connecting frame 23, thereby changing the angle between the scraper 24 and the rotating shaft 13. By changing the distance and using different inner walls of the pipe, after adjusting the height of the rotating shaft 13 and the position of the scraper 24, the controller 27 controls the drive motor 15 to run. The drive motor 15 drives the active gear 16 to rotate. The rotation of the active gear 16 and the internal meshing of the driven gear 14 drive the rotating shaft 13 to rotate, thereby causing the scraper 24 to rotate and scrape away the dirt on the inner wall of the pipe. At the same time, the water supply pump 29 is controlled to run, and the cleaning water inside the water storage tank 3 or the external water source is transported. The water is discharged through the high-pressure nozzle 11 to rinse the inner wall of the pipe.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
