Description

Technical Field

[0001] This utility model relates to the field of pipe cleaning machines, specifically a sealing component structure for a pipe cleaning machine. Background Technology

[0002] Pipe cleaning machines are specialized equipment used to remove blockages in sewers, toilets, and other pipes. The sealing components of these machines are core functional parts, requiring continuous operation for extended periods under high-pressure water flow. Traditional single sealing rings, such as O-rings, are prone to "extrusion deformation" under pressures exceeding 10 MPa, leading to a decrease in sealing contact pressure and water leakage, thus failing to meet high-pressure cleaning requirements. According to statistics from municipal dredging operations, 35% of dredging machine downtime is due to sealing component failure, and seal replacement costs account for 40% of equipment maintenance costs. Therefore, designing a reliable high-pressure sealing component structure for dredging machines is crucial for improving operational efficiency and reducing maintenance costs. Utility Model Content

A high-pressure pipe 44 is installed on the surface of the connector 43. A rotary cleaning drill bit 45 is installed at the front end of the high-pressure pipe 44.

[0025] In practical use: A drive motor 41 is installed in the middle of the surface of the mounting bracket 1. After the drive motor 41 works, it drives the high-pressure pump 42 to work. The high-pressure pump 42 pumps water into the connector 43 at the outlet end. The high-pressure water is sprayed out at high speed through the high-pressure pipe 44 connected to the connector 43 and the rotating cleaning drill bit 45. The high-pressure water pushes the rotating cleaning drill bit 45 to rotate forward, thereby cleaning and unblocking the inner wall of the pipe.

[0026] Please see Figure 1 , Figure 3 The sealing assembly 5 includes a sealing sleeve 51 disposed between the connector 43 and the high-pressure pipe 44. One end of the high-pressure pipe 44 is connected to a mating sleeve 52. The mating sleeve 52 and the connector 43 are mated together by inserting into the sealing sleeve 51. Two sealing rings 53 are installed inside the sealing sleeve 51. Both the mating sleeve 52 and the connector 43 have annular grooves 54 on their surfaces. The sealing rings 53 are embedded in the annular grooves 54. Two semi-circular clamps 55 are provided on the outside of the sealing sleeve 51. The bottoms of the two semi-circular clamps 55 are hinged together. The tops of the two semi-circular clamps 55 are each equipped with a locking buckle 56. The two semi-circular clamps 55 are fixedly connected by the locking buckle 56.

[0027] In practical use: A sealing sleeve 51 is provided between the connector 43 and the high-pressure pipe 44. One end of the high-pressure pipe 44 is connected to a mating sleeve 52. The connector 43 and the mating sleeve 52 are inserted into the sealing sleeve 51 for mating connection. Two sealing rings 53 are installed inside the sealing sleeve 51. The sealing rings 53 are embedded in the annular grooves 54 opened on the surfaces of the mating sleeve 52 and the connector 43, so that the sealing sleeve 51, the mating sleeve 52 and the connector 43 are all provided with a sealing structure. The sealing sleeve 51, the mating sleeve 52 and the connector 43 are tightened and fixed by two semi-circular clamps 55 provided on the outside of the sealing sleeve 51 to ensure the connection is sealed. The semi-circular clamps 55 are fixedly connected by the locking buckle 56 at the top to ensure that the mating sleeve 52 and the connector 43 maintain a sealed connection under high-pressure water flow environment and avoid leakage that may affect the dredging operation.

[0028] Please see Figure 4 A support base 6 is installed at the front end of the mounting frame 1. A mounting frame 7 is installed on the top of the support base 6. Bearing seats 8 are installed on both sides inside the mounting frame 7. A winding drum 9 is provided inside the mounting frame 7. The middle part of the winding drum 9 is rotatably installed inside the bearing seat 8 via a rotating shaft. The high-pressure pipe 44 is wound on the surface of the winding drum 9. A rocker wheel 10 is fixedly installed at one end of the winding drum 9.

[0029] In practical use: a support base 6 is installed on the front end of the surface of the mounting frame 1, a mounting frame 7 is installed on the top of the support base 6, and bearing seats 8 are installed on both sides inside the mounting frame 7. The winding drum 9 is rotatably installed inside the bearing seat 8 through the central rotating shaft. When the rocker wheel 10 is shaken, it drives the winding drum 9 to rotate, which further drives the high-pressure tube 44 to be wound up, making it easy to store and organize the high-pressure tube 44.

[0030] Please see Figure 3 Both ends of the two semi-circular clamps 55 are connected to limit rings 11, and both ends of the sealing sleeve 51 are in contact with the inner side of the limit rings 11.

[0031] In practical use: Limiting rings 11 are connected to the inner sides of both ends of the two semi-circular clamps 55. The two ends of the sealing sleeve 51 are in contact with the inner wall of the limiting rings 11. When the semi-circular clamps 55 are tightened, the two ends of the sealing sleeve 51 are inside the semi-circular clamps 55, so as to prevent the sealing sleeve 51 from loosening and thus affecting the sealing performance of the high-pressure pipe 44 connection.

[0032] Please see Figure 4 Anti-detachment baffles 12 are fixedly installed at both ends of the winding drum 9.

[0033] In practical use: Anti-detachment baffles 12 are fixedly installed at both ends of the winding drum 9 to prevent the high-pressure pipe 44 from detaching during the winding process.

[0034] Please see Figure 1 , Figure 2 A pressure gauge 13 is installed on one side of the outlet end of the high-pressure pump 42.

[0035] In practical use: The pressure gauge 13 installed on one side of the outlet end of the high-pressure pump 42 is used to know the water pressure inside the high-pressure pipe 44 during unblocking.

[0036] Please see Figure 1 A control box 14 is mounted on the surface of the mounting bracket 1. The drive motor 41 is electrically connected to the control box 14, and the control box 14 is electrically connected to an external power supply.

[0037] In practical use: when the control box 14 is connected to the external power supply, the drive motor 41 is energized and drives the high-pressure pump 42 to run; when the control box 14 is disconnected from the external power supply, the equipment stops running.

[0038] A sealing sleeve 51 is provided between the connector 43 and the high-pressure pipe 44. One end of the high-pressure pipe 44 is connected to a mating sleeve 52. The connector 43 and the mating sleeve 52 are inserted into the sealing sleeve 51 for mating connection. Two sealing rings 53 are installed inside the sealing sleeve 51. The sealing rings 53 are embedded in the annular grooves 54 opened on the surfaces of the mating sleeve 52 and the connector 43, so that the sealing sleeve 51, the mating sleeve 52 and the connector 43 are all provided with a sealing structure. The sealing sleeve 51, the mating sleeve 52 and the connector 43 are tightened and fixed by two semi-circular clamps 55 provided on the outside of the sealing sleeve 51 to ensure the connection is sealed. The semi-circular clamps 55 are fixedly connected by the locking buckle 56 at the top to ensure that the mating sleeve 52 and the connector 43 maintain a sealed connection under high-pressure water flow environment and avoid leakage that may affect the dredging operation.
