Abstract
Description
Technical Field
[0001] This utility model relates to the field of municipal pipeline cleaning technology, and in particular to an internal cleaning component for municipal pipelines. Background Technology
[0002] Municipal pipelines come in many categories, among which drainage pipelines, including rainwater main pipes and sewage branch pipes, are the most frequently cleaned. Rainwater main pipes are generally DN600-DN3000 in size, while sewage branch pipes are generally DN200-DN400 in size. In general, the types of pipes laid out in cities are limited to a few specifications.
[0003] These pipes, due to their long-term transport of sewage, rainwater, and other media, are prone to problems such as grease buildup, silt deposition, and biofilm adhesion, leading to reduced flow capacity or even blockages. Once a blockage occurs, or before the rainy season, internal cleaning is necessary.
[0004] Municipal pipelines can be cleaned manually or mechanically. However, manual dredging is not only inefficient but also poses safety hazards.
[0005] Traditional mechanical cleaning methods generally include mechanical equipment dredging and high-pressure water jet cleaning. Mechanical dredging equipment includes tools such as winch-type dredging machines and auger drills, which remove blockages through physical cutting. However, it usually still requires manual operation in the well, which limits the working space and can easily damage the inner wall of municipal pipelines.
[0006] High-pressure water jet cleaning typically uses 10-280MPa high-pressure water flow to remove dirt from pipe walls. It is convenient and efficient and does not damage the inner wall of municipal pipelines. However, it is difficult to use it to clean completely clogged pipes, and the water pipes are difficult to extend deep into municipal pipelines. Therefore, it is only suitable for short to medium distance pipelines. Utility Model Content
[0007] In view of this, the purpose of this utility model is to propose an internal cleaning component for municipal pipelines to solve the problems in the prior art.
[0008] To achieve the above objectives, this utility model provides an internal cleaning assembly for municipal pipelines, including a flushing head for spraying high-pressure water jets, the flushing head being fixedly connected to the front end of a connecting cylinder, and the internal cleaning assembly further including:
[0009] A drive base is fixedly connected to the outer wall of the connecting cylinder. The drive base is cylindrical and has several rollers arranged at equal angles on its outer ring. The drive base also has a drive mechanism for driving the rollers to rotate.
[0010] Furthermore, the connecting cylinder is also equipped with a water supply pipe and a cable. The front end of the water supply pipe is connected to the flushing head for water supply, and the front end of the cable is connected to the drive base for powering the electrical equipment inside the drive base.
[0011] Furthermore, a front nozzle is provided at the center of the front end of the rinsing head, and a number of side nozzles arranged at equal angles are also provided on the outer ring of the rinsing head.
[0012] Furthermore, the outer ring of the drive base is provided with a movable groove, the roller is movably connected in the movable groove, and the roller is also rotatably connected to a rotating shaft, the rotating shaft being slidably connected in the drive base.
[0013] Furthermore, the driving mechanism includes a drive motor and a drive roller, the drive roller being connected to the output shaft of the drive motor, and the drive roller being connected to a rotating shaft via a transmission belt.
[0014] Furthermore, a bushing is rotatably connected to the rotating shaft, and a spring push rod is connected to the inner side of the bushing to apply an outward thrust to the rotating shaft.
[0015] Furthermore, the drive base is also provided with a mating wheel, which is connected to the drive roller and the rotating shaft on the same transmission belt and supports the transmission belt into a triangular shape. A bushing is also rotatably connected to the rotating shaft of the mating wheel, and a spring push rod is also provided inside the bushing to apply an outward thrust to the mating wheel.
[0016] Furthermore, the elastic push rod includes a slide rod and a fixed cylinder. The fixed cylinder is fixedly connected to the drive base. The inner end of the slide rod is slidably connected to the fixed cylinder, and the outer end of the slide rod is fixedly connected to the corresponding bushing. A spring is also provided inside the fixed cylinder on the inner side of the slide rod.
[0017] The beneficial effects of this utility model are as follows: 1. A high-pressure water jet flushing head is used to clean municipal pipelines. The flushing head has a front nozzle at its center and several side nozzles arranged at equal angles on its outer ring. By flushing the inner wall of the municipal pipeline at a vertical angle through multiple side nozzles, the silt and dirt adhering to the pipeline wall can be efficiently removed, and the sprayed water can carry away the silt, dirt, and debris. This achieves the goal of cleaning the pipeline inner wall while simultaneously removing the removed debris, preventing it from adhering to the pipeline inner wall again.
[0018] 2. The flushing head is fixed to the front end of the connecting cylinder, which supports the flushing head. A drive base is fixedly connected to the outer wall of the connecting cylinder. The outer ring of the drive base has several rollers arranged at equal angles. These rollers rest against the inner wall of the municipal pipeline. Since there are only a limited number of municipal pipeline specifications used for drainage, only a few devices conforming to these specifications need to be designed. The drive base also contains a drive mechanism for rotating the rollers. Together with the rollers resting against the inner wall of the pipeline, this mechanism drives the entire device to move within the pipeline.
[0019] 3. The outer rim of the roller has a serrated pattern to increase friction and prevent slippage. Additionally, the outer rim of the drive base has a movable groove, to which the roller is movably connected. A spring-loaded push rod is installed within the drive base to apply an outward thrust to the rotating shaft. Therefore, the roller is always pressed against the inner wall of the pipe, ensuring sufficient adhesion. When encountering obstacles, the roller can also retract appropriately for easier passage.
[0020] 4. The drive mechanism drives the rotating shaft (roller) to rotate via a transmission belt. To ensure the transmission belt remains taut and provides sufficient driving force as the rotating shaft (roller) moves, a mating wheel is installed inside the drive base. A spring-loaded push rod is also installed inside the mating wheel to apply an outward thrust. Therefore, when the rotating shaft (roller) retracts, the mating wheel expands outward, ensuring the transmission belt remains taut. Attached Figure Description

[0030] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, manual dredging is not only inefficient but also poses safety hazards, while mechanical dredging equipment requires manual operation, which limits the working space and can easily damage the inner wall of municipal pipelines. Therefore, this utility model adopts a high-pressure water jet cleaning method to clean the inside of municipal pipelines.
[0031] Specifically, a flushing head 102 is designed, which is fixedly connected to the front end of the connecting cylinder 101. A water supply pipe 105 is also provided inside the connecting cylinder 101. The front end of the water supply pipe 105 is connected to the flushing head 102 for water supply. The rear end of the water supply pipe 105 is connected to a high-pressure water pump, which not only supplies water but also increases the water pressure, enabling the flushing head 102 to spray a high-pressure water stream.
[0032] A front nozzle 103 is provided at the center of the front end of the flushing head 102, and a number of side nozzles 104 arranged at equal angles are provided on the outer ring of the flushing head 102. Each of the front nozzle 103 and the side nozzles 104 is provided with a solenoid valve to control the water flow.
[0033] A high-pressure water jet flushing head 102 is used to clean municipal pipelines. The flushing head 102 has a front nozzle 103 at its center and several side nozzles 104 arranged at equal angles on its outer ring. By flushing the inner wall of the municipal pipeline at a vertical angle through multiple side nozzles 104, the silt and dirt adhering to the pipeline wall can be efficiently removed, and the sprayed water can carry away the silt, dirt, and debris. This cleans the pipeline wall while simultaneously removing the removed debris, preventing it from re-adhering to the pipeline wall.
[0034] The second aspect of this utility model is as follows: Figure 2 and Figure 3 As shown, since it is difficult for pipes to extend deep into municipal pipelines, high-pressure water jet cleaning is only suitable for short to medium-distance pipelines. To solve this problem, in this embodiment, a drive base 106 is fixedly connected to the outer wall of the connecting cylinder 101. The drive base 106 is cylindrical, and a number of rollers 107 arranged at equal angles are provided on the outer ring of the drive base 106. The drive base 106 is also provided with a drive mechanism for driving the rollers 107 to rotate.
[0035] The drive mechanism includes a drive motor 114 and a drive roller 113. The drive roller 113 is connected to the output shaft of the drive motor 114, and the drive roller 113 is also connected to the rotating shaft 110 via a transmission belt 112.
[0036] Preferably, the outer ring of the roller 107 is provided with a serrated pattern 108 to increase the friction of the roller 107 and prevent the roller 107 from slipping.
[0037] Since there are only a limited number of municipal pipe specifications used for drainage, only a few types of equipment that conform to these specifications need to be designed. The rollers 107 with serrated edges 108 are supported on the inner wall of the municipal pipe, and a drive mechanism for driving the rollers 107 to rotate is also provided in the drive base 106. The two work together to drive the entire equipment to move inside the pipe.
[0038] The third aspect of this utility model is as follows: Figure 3 and Figure 4As shown, to ensure that the roller 107 always presses (supports) against the inner wall of the municipal pipeline, and that it can smoothly pass through obstacles that cannot be washed away from the inner wall of the pipeline, this embodiment has a movable groove 109 on the outer ring of the drive base 106. The roller 107 is movably connected in the movable groove 109, and the roller 107 is also rotatably connected to the rotating shaft 110, which is slidably connected in the drive base 106.
[0039] In addition, a bushing 111 is rotatably connected to the rotating shaft 110, and a spring push rod 115 is connected to the inner side of the bushing 111 to apply an outward thrust to the rotating shaft 110.
[0040] The roller 107 is movably connected to the movable groove 109, and a spring-loaded push rod 115 is provided in the drive base 106 to apply an outward thrust to the rotating shaft 110. Therefore, the roller 107 is always pressed against the inner wall of the pipe, ensuring sufficient adhesion at all times. When encountering obstacles, the roller 107 can also retract appropriately to facilitate passage.
[0041] In order to ensure that the transmission belt 112 remains taut to provide sufficient driving force when the rotating shaft 110 (roller 107) moves, a mating wheel 116 is provided in the drive base 106. The mating wheel 116, the drive roller 113, and the rotating shaft 110 are all connected to the same transmission belt 112, which supports the transmission belt 112 into a triangular shape. A bushing 111 is also rotatably connected to the rotating shaft of the mating wheel 116, and a spring push rod 115 is provided inside the bushing 111 to apply an outward thrust to the mating wheel 116.
[0042] The elastic push rod 115 includes a slide rod 117 and a fixed cylinder 118. The fixed cylinder 118 is fixedly connected to the drive base 106. The inner end of the slide rod 117 is slidably connected to the fixed cylinder 118, and the outer end of the slide rod 117 is fixedly connected to the corresponding bushing 111. A spring 119 is also provided in the fixed cylinder 118 inside the slide rod 117.
[0043] Therefore, when the rotating shaft 110 (roller 107) retracts inward, the mating wheel 116 can expand outward, so that the transmission belt 112 can always be taut.
[0044] In summary, this utility model employs a high-pressure water jet flushing head 102 that extends into the interior of municipal pipelines to clean them. A front nozzle 103 is located at the center of the front end of the flushing head 102, and several side nozzles 104 arranged at equal angles are also provided on the outer ring of the flushing head 102. By flushing the inner wall of the municipal pipeline at a vertical angle through multiple side nozzles 104, the mud and dirt adhering to the inner wall of the pipeline can be efficiently removed, and the sprayed water jet can carry away the mud, dirt, and debris. This achieves the cleaning of the inner wall of the pipeline while simultaneously removing the cleaned debris, preventing it from re-adhering to the inner wall of the pipeline. A flushing head 102 is fixed to the front end of a connecting cylinder 101, which supports the flushing head 102. A drive base 106 is fixedly connected to the outer wall of the connecting cylinder 101. The outer circumference of the drive base 106 has several rollers 107 arranged at equal angles. These rollers 107 rest against the inner wall of the municipal pipeline. Since there are only a limited number of municipal pipeline specifications used for drainage, only a few devices conforming to these specifications need to be designed. A drive mechanism for rotating the rollers 107 is also provided within the drive base 106. Together with the rollers 107 resting against the inner wall of the pipeline, this mechanism drives the entire device to move within the pipeline.
[0045] The outer ring of roller 107 has a serrated pattern 108 to increase the friction of roller 107 and prevent it from slipping. Additionally, the outer ring of drive base 106 has a movable groove 109, to which roller 107 is movably connected. A spring-loaded push rod 115 is installed inside drive base 106 to apply an outward thrust to rotating shaft 110. Therefore, roller 107 is always pressed against the inner wall of the pipe, ensuring sufficient adhesion. When encountering obstacles, roller 107 can also retract appropriately for easy passage. The drive mechanism drives rotating shaft 110 (roller 107) to rotate via transmission belt 112. To ensure that transmission belt 112 remains taut to provide sufficient driving force as rotating shaft 110 (roller 107) moves, a mating wheel 116 is installed inside drive base 106. A spring-loaded push rod 115 is also installed inside mating wheel 116 to apply an outward thrust to mating wheel 116. Therefore, when the rotating shaft 110 (roller 107) retracts inward, the mating wheel 116 can expand outward, so that the transmission belt 112 can always be taut.
