[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-5 The present invention provides a technical solution:

[0025] An automated municipal pipeline blockage and cleaning device includes a main body 1, a battery box 2, a drive structure, a push structure, and cleaning components disposed outside the main body 1. The battery box 2 is disposed at the end of the main body 1, and the push structure is disposed at the front end of the main body 1. The push structure is detachably connected to the main body 1. The drive structure is symmetrically disposed at both the front and rear ends of the bottom of the main body 1. The drive structure includes a suspension box 3. The outer wall of the suspension box 3 is disposed of a drive motor 4. The output end of the drive motor 4 is connected to a moving wheel 5. The main control box 6 is disposed on the main body 1. The outer wall of the main control box 6 is disposed of a plurality of sensors 7. The bottom of the main body 1 is disposed of an adsorption structure.

[0026] The front end of the main body 1 is provided with a protruding ring 8, and a camera 9 is provided on the top of the protruding ring 8. Spotlights 10 are symmetrically arranged on both sides of the protruding ring 8. The internal image information is collected by using the camera 9 on the protruding ring 8, and the spotlights 10 provide illumination.

[0027] The pushing structure includes a storage column 11, inside which is a buckle plate 12. A hydraulic cylinder 13 is located at the center of the buckle plate 12. The output end of the hydraulic cylinder 13 is connected to a spring pressure plate 14. Several air pumps 15 are located on the inner wall of the buckle plate 12. The output end of the air pumps 15 is connected to an air pipe 16. An air guide ring 17 is located on the inner wall of the spring pressure plate 14. The air pipe 16 is connected to the air guide ring 17. A hollow rubber bladder 18 is located on the outer wall of the spring pressure plate 14. The rubber bladder is connected to the air passage of the air guide ring 17. The hydraulic cylinder 13 pushes the entire spring pressure plate 14 and the external components. The air pumps 15 can be used to inflate the rubber bladder, so that the whole structure can cooperate to block the garbage and push it outward.

[0028] The cleaning components are arranged in three parts, distributed on both sides and top of the main body 1. A cavity is opened at the corresponding position of the main body 1, and a liquid storage tank 19 is arranged in the cavity. A high-pressure liquid pump is installed inside the liquid storage tank 19, and a drain pipe 20 is connected to the outside of the liquid storage tank 19. An arc-shaped guide plate 21 is connected to the outside of the drain pipe 20. Several nozzles 22 are arranged symmetrically on both sides of the guide plate 21. A decontamination vibration structure is arranged in the middle of the guide plate 21. The high-pressure liquid pump in the liquid storage tank 19 can be used to spray the liquid inside through the nozzles to form a high-pressure water jet head, which can remove the garbage adhering to the pipe. In conjunction with the decontamination vibration structure, the effect of efficiently removing blockages and adhering substances can be achieved.

[0029] The decontamination vibration structure includes a cast iron plate 23. Two protruding plates 24 are located on the outer wall of the cast iron plate 23. A directional motor is installed on the outer wall of one of the protruding plates 24. The output end of the directional motor is connected to a directional shaft 25. A linkage rod 26 is connected to the middle of the directional shaft 25. A connecting disc 27 is connected to the outer end of the linkage rod 26. An electric telescopic rod 28 is connected to the outer side of the connecting disc 27. A vibrating rod 29 is connected to the outer side of the electric telescopic rod 28. Activating the directional motor and the directional shaft 256 drives the vibrating rod 29 to adjust its direction. The electric telescopic rod 28 can also cause the vibrating rod 29 to extend and retract, contacting the inner wall of the pipe to vibrate and remove adhering substances. The vibrating rod parameters are: frequency range: 8000-12000 rpm (medium-high frequency); amplitude: 0.5-2mm; vibrator head material: hard alloy or stainless steel, corrosion resistant.

[0030] The adsorption structure includes an adsorption hood 30, and a turbo vacuum pump 31 is provided on the outer wall of the adsorption hood 30. The body 1 has a sludge storage chamber inside. The turbo vacuum pump 31 is used to suck some of the fallen debris into the sludge storage chamber through the adsorption hood 30.

[0031] The main control box 6 includes an image recognition module, a positioning module, a power control module, a power supply module, a wireless transmission module, and an intelligent monitoring module. The image recognition and positioning module is equipped with a waterproof industrial camera and a laser rangefinder at the front of the machine, used to detect the condition of the inner wall of the pipeline and the distribution of debris, and to realize autonomous operation path planning. The power control module contains a PLC control unit, an air pump control unit, a motor drive unit, and a wireless communication unit, which can perform sealing and cleaning operations through ground remote control or preset programs.

[0032] Power control module: Powered by lithium battery pack or cable, supporting continuous operation for more than 4 hours, including power monitoring function; Intelligent monitoring module: Pressure sensor and airtightness detection unit are installed at the sealing mechanism to provide real-time feedback on sealing status; Wireless communication module: Used for remote wireless control.

[0033] Working Principle: The device is manually or automatically introduced into the municipal pipeline. The drive motor 4 in the drive structure rotates the moving wheels 5, enabling the device to move forward or backward within the pipeline. During operation, the positioning module and image recognition module in the main control box 6 work together, combined with the front-end camera 9 and sensor 7, to monitor the device's position, pipeline shape, and surrounding environment in real time, achieving precise positioning. Adsorption Fixation and Sealing Operation: When the device moves to the target cleaning area, the bottom adsorption structure activates the turbine vacuum pump 31, creating negative pressure within the pipeline through the adsorption hood 30, ensuring stable adhesion of the device and preventing drift or rebound during the cleaning process. Subsequently, the push structure activates the hydraulic cylinder 13, pushing the pressure plate 14, causing the rubber bladder 18 to expand towards the inner wall of the pipeline, forming a sealing contact. Simultaneously, the air pump 15 injects gas into the air guide ring 17 and the rubber bladder 18 through the air pipe 16, causing the rubber bladder 18 to expand, thereby sealing the pipeline, achieving temporary water and dirt stoppage, and pushing debris outwards. After sealing is completed, the device automatically activates the cleaning components. The liquid in the storage tank 19, driven by a high-pressure liquid pump, is transported to the guide plate 21 through the drain pipe 20. The guide plate 21 guides the liquid flow to multiple nozzles 22. The nozzles 22 use high-pressure water flow to flush the inner wall of the pipe, washing away surface dirt and discharging it with the water flow. Vibration cleaning assists in cleaning. To clean sludge with strong adhesion or severe adhesion, the cleaning vibration structure in the device is activated synchronously. The directional motor drives the directional shaft 25 to rotate, so that the vibrating rod 29 can achieve multi-angle adjustable vibration through the coordinated action of the linkage rod 26, the connecting plate 27 and the electric telescopic rod 28. The vibrating rod 29 reciprocates at high speed, transmitting mechanical vibration to the pipe wall, breaking the adhesion between the sludge and the pipe wall, causing it to fall off, and is thoroughly flushed away with high-pressure spraying. Sludge collection and discharge: The sludge after vibration and spraying is flushed into the pipe fluid or directly sucked into the sludge storage chamber in the main body 1. The sludge storage chamber forms mud-water separation under negative pressure, which helps with subsequent centralized discharge and treatment. For specific needs, waste can be temporarily stored and then manually removed. After the cleaning operation is completed, the main control box 6 controls the orderly shutdown of each system: the vibrator 29 stops vibrating, the air pump 15 exhausts air to retract the rubber bladder 18, the hydraulic cylinder retracts the pressure plate 14, and the adsorption structure releases the vacuum adsorption. The drive system restarts, the device moves backward or in a turning direction, returning to the pipeline outlet, completing the entire automated cleaning process. Remote monitoring and data recording are implemented. The entire operation process is transmitted in real time to a remote terminal via an image recognition module and a wireless transmission module, allowing the operator to monitor and control the process. Simultaneously, the intelligent monitoring module records operation data, running trajectory, and cleaning status for subsequent analysis, maintenance, and management.
