Description

Technical Field

[0001] This utility model relates to the field of pipeline dredging technology, and in particular to an adjustable pipeline cleaning robot. Background Technology

[0002] Pipeline dredging refers to the process of removing dirt, sediment, debris, and other pollutants from inside pipelines using physical or chemical methods to restore their normal operation and function. From the perspective of urban governance, pipeline dredging plays an irreplaceable role in ensuring the hydraulic efficiency of urban drainage systems: Firstly, by regularly removing biofilm and sediment layers from pipe walls, the cross-sectional area of ​​the pipeline can be maintained, preventing a decrease in drainage capacity due to reduced flow area; secondly, dredging can effectively prevent secondary disasters such as road flooding and sewage backflow caused by complete pipeline blockage, especially preventative dredging before the rainy season, which can significantly improve urban flood control and drainage capabilities; thirdly, timely removal of sediments containing heavy metals and organic pollutants can reduce the risk of pollutants overflowing into natural water bodies with rainwater, which has important environmental benefits for controlling non-point source pollution and protecting aquatic ecosystems.

[0003] In existing technologies, traditional pipe cleaning methods mainly rely on manual cleaning, high-pressure water jet flushing, or single mechanical unblocking, which have many technical limitations and application defects, specifically as follows: Traditional cleaning equipment is usually only suitable for pipes of a specific diameter, and lacks the ability to flexibly adjust to circular pipes of different diameters (especially variable diameter pipes), resulting in unstable cleaning effects, and may even be unable to operate due to equipment size mismatch; some mechanical cleaning devices use fixed rollers or support structures, which are prone to displacement or jamming when running in the pipe, affecting the cleaning process, and may even damage the inner wall of the pipe. Therefore, we propose an adjustable pipe cleaning robot to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 As shown, an adjustable pipe cleaning robot is disclosed, comprising a housing 1, with a dual-axis motor 3 fixedly connected inside the housing 1. Multiple heat dissipation holes are provided on the bottom outer wall of the housing 1. Mounting brackets 2 are fixedly connected to both ends of the housing 1. Existing high-pressure water guns can be mounted on the mounting brackets 2, which, together with nylon brushes 14, perform cleaning. Circular holes are provided on the outer walls of both mounting brackets 2, and the inner walls of the two circular holes are rotatably connected to the outer walls of the two output shafts of the dual-axis motor 3. Lead screws 4 are fixedly connected to the outer walls of the two output shafts of the dual-axis motor 3. Moving sleeves 5 are threaded onto the outer walls of the two lead screws 4. The dual-axis motor 3 controls the extension and retraction of the moving sleeves 5 by forward and reverse rotation. The two lead screws 4 are symmetrically arranged and use precision threads to engage with the moving sleeves 5 to ensure synchronous extension and retraction.

[0021] Three supports 6 are rotatably connected to the outer walls of the two movable sleeves 5. One end of each support 6 is rotatably connected to a rotating frame 7 via an existing pin. One end of the rotating frame 7 is rotatably connected to the outer wall of the mounting frame 2 via an existing pin. A servo motor 8 is fixedly connected to the outer wall of the rotating frame 7. A roller 9 is rotatably connected to the outer wall of the rotating frame 7. A bevel gear 10 is fixedly connected to the outer wall of the roller 9 and the outer wall of the output shaft of the servo motor 8. The two bevel gears 10 are meshed together. The six rollers 9 are evenly distributed in a circle. The robot's forward, backward and turning movements are realized through differential control of the servo motor 8.

[0022] The outer wall of the housing 1 is provided with a cleaning component, which includes an end plate 12. A circular sleeve 11 is rotatably provided on the outer wall of the housing 1. A bearing is fixedly connected to the outer wall of the circular sleeve 11. The inner ring of the bearing is fixedly connected to the outer wall of the housing 1. The circular sleeve 11 and the end plate 12 are fixedly connected by existing bolts. The circular ring 13 can be removed from the annular groove and replaced by removing the bolts. A DC motor 15 is fixedly connected to the outer wall of the housing 1. The DC motor 15 and the dual-axis motor 3 have a certain waterproof capability. A spur gear 16 is fixedly connected to the outer wall of the output shaft of the DC motor 15. An annular rack is fixedly sleeved on the outer wall of the circular sleeve 11. The annular rack and the spur gear 16 are meshed. The DC motor 15 drives the spur gear 16 to mesh with the annular rack on the outer wall of the circular sleeve 11, thereby driving the circular sleeve 11 and the end plate 12 to rotate.

[0023] The outer wall of the circular sleeve 11 has an annular groove, and a circular ring 13 is placed inside the annular groove. The outer wall of the end plate 12 has a sliding hole, and the inner wall of the sliding hole is slidably connected to the outer wall of the circular sleeve 11. Nylon brushes 14 are evenly fixedly connected to the outer wall of the circular ring 13. Nylon brushes 14 are suitable for flexible cleaning of the inner walls of pipes of different materials. The outer walls of the two mounting brackets 2 are each fixedly connected with three guide rods. The outer walls of the two movable sleeves 5 are each provided with three guide holes. The inner walls of the six guide holes are slidably connected to the outer walls of the six guide rods respectively. The guide holes on the outer wall of the movable sleeve 5 are slidably engaged with the guide rods to ensure the linear movement of the movable sleeve 5.

[0024] Working Principle: During use, the entire unit is placed inside the circular pipe requiring cleaning. It is powered by an external power source via a flexible cable. Depending on the diameter of the circular pipe, a dual-axis motor 3 drives two lead screws 4 to rotate. The rotation of the lead screws 4 causes two moving sleeves 5 to move outwards. The outward movement of the moving sleeves 5 causes six connected rotating frames 7 to rotate. At the rotational connection between the rotating frame 7 and the mounting frame 2, multiple servo motors 8 drive multiple connected bevel gears 10 to rotate, which in turn drives another bevel gear 10 to rotate, causing multiple rollers 9 to rotate. The entire unit travels inside the circular pipe via these rollers 9. A DC motor 15 drives a spur gear 16 to rotate, which in turn drives a ring rack. The ring rack rotates, causing a circular sleeve 11 to rotate, which in turn drives a ring 13 and an end plate 12 to rotate. The ring 13 rotates, causing multiple nylon brushes 14 to rotate. These nylon brushes 14 clean the inner wall of the circular pipe. This system can be used with existing liquid cleaning solutions.

[0025] It should be noted that, in actual use, an existing synchronous controller can be added. The synchronous controller is electrically connected to the dual-axis motor 3, servo motor 8, and DC motor 15 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is merely to illustrate the beneficial effects that this hardware structure improvement can achieve, based on common knowledge.

[0026] All standard parts used in this utility model can be purchased from the market. Irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. Furthermore, the structure and principle of the components known to those skilled in the art can be learned by those skilled in the art through technical manuals or conventional experimental methods.
