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

[0024] Please see Figure 1 , Figure 3 and Figure 5 A tracked remote-controlled sludge removal robot for sewage treatment includes a walking mechanism and a sludge removal mechanism. The robot is wirelessly connected to an industrial remote controller, enabling remote control operation and making operations more flexible. It also offers superior safety, eliminating the risk of personnel injury. The walking mechanism, used for the robot's movement in sludge environments, includes a track assembly 1, a robot shell 2, a hydraulic motor 3, a self-cleaning underwater camera 4, omnidirectional marker lights 5, and a toxic gas detection module 6. The sludge removal mechanism, used for cleaning sludge in sludge ponds, includes a high-pressure nozzle 7, a high-pressure water pipe 8, a hydraulic cylinder assembly 9, and a bucket 10. The robot utilizes the hydraulic motor 3 to drive the track assembly 1, combined with the high-pressure nozzle 7 to disperse the sludge and the bucket to clean it, replacing manual cleaning of sewage sludge treatment plants and preventing injuries caused by direct contact with toxic gases.

[0025] The track assembly 1 is fixedly connected to the hydraulic motor 3 by bolts. The hydraulic motor 3 enables the tracked remote-controlled dredging robot to adopt a hydraulic control system, hydraulic power, explosion-proof safety, large driving force, suitable for heavy-duty direct drive, explosion-proof safety and reliability, achieving safe and efficient dredging effect. In addition, the tracked remote-controlled dredging robot can perform mobile dredging, making the dredging operation more efficient. The tracked remote-controlled dredging robot is suitable for wading operations. The robot has a compact overall structure, a dedicated chassis design, higher strength, and lighter weight, and can perform wading operations. At the same time, the hydraulic motor 3 adopts a high load-bearing track design, making the tracked remote-controlled dredging robot more capable of crossing obstacles.

[0026] Please see Figure 2 and Figure 4 The robot shell 2 is fixed to the track assembly 1 by riveting. The robot shell 2 is connected to the visual self-cleaning underwater camera 4 by screws. The top of the robot shell 2 is glued to the vehicle's all-around marker light 5. The top of the robot shell 2 is bolted to install a toxic gas detection module 6. The toxic gas detection module 6 is designed so that once toxic gas is detected, it will send a signal to the remote control.

[0027] The top of the bucket 10 is threaded with several high-pressure nozzles 7. The bucket 10 is connected to the robot shell 2 via a pin. The top of the bucket 10 is fitted with a high-pressure water pipe 8 via a quick-connect fitting. The bucket 10 is internally connected to the high-pressure water pipe 8 and the high-pressure nozzles 7. The inside of the bucket 10 is fitted with an auger disc via a flange and bearings. The bottom of the bucket 10 is connected to the inlet pipe of a sludge pump located outside the sewage tank via a flange. The outlet pipe of the sludge pump is connected to a sewage collection device via a flange.

[0028] The hydraulic cylinder assembly 9 includes a first hydraulic cylinder 901 and a second hydraulic cylinder 902. The arrangement of the first hydraulic cylinder 901 and the second hydraulic cylinder 902 enables the adjustment of the operating angle of the high-pressure nozzle 7 and the bucket 10. The two ends of the second hydraulic cylinder 902 are respectively connected to the top of the robot shell 2 and the bucket 10 via pins. The two ends of the first hydraulic cylinder 901 are respectively connected to the robot shell 2 and the high-pressure nozzle 7 via pins.

[0029] Please see Figure 5 , Figure 6 , Figure 7 and Figure 8The outer flange of the high-pressure water pipe 8 is connected to a connecting pipe 11. A first filter plate 12 is installed at one end of the connecting pipe 11, located outside the high-pressure water pipe 8. A second filter plate 13 is fixedly installed on the inner wall of the connecting pipe 11, located outside the first filter plate 12. Since the diameter of the filter holes on the second filter plate 13 is larger than the diameter of the filter holes on the connecting pipe 11, the water before entering the high-pressure water pipe 8 will first pass through the connecting pipe 11. The water entering the connecting pipe 11 will first pass through the second filter plate 13 for the first filtration. The water after the first filtration will then flow to the first filter plate 12 for the second filtration, removing impurities from the water. After two filtrations, the water flows into the high-pressure water pipe 8, thus preventing impurities in the water from clogging the high-pressure nozzle 7. Both the connecting pipe 11 and the high-pressure water pipe 8 are movably fitted with elastic clamps 14. The upper end of the elastic clamp 14 is threaded with a fastening bolt 15. The fastening bolt 15 allows the elastic clamp 14 to be installed in the connecting pipe 11 or the high-pressure water pipe 8. The lower end of the elastic clamp 14 is fixedly fitted with a suction cup 16. The suction cup 16 allows the connecting pipe 11 or the high-pressure water pipe 8 to be adsorbed onto the tracked remote-controlled sludge removal robot, thereby fixing the installation position of the connecting pipe 11 or the high-pressure water pipe 8.

[0030] Working principle: When in use, firstly, the tracked remote-controlled sludge dredging robot is moved to the sewage sludge treatment pool using a hoisting device. Since the tracked remote-controlled sludge dredging robot is wirelessly connected to an industrial remote controller, the industrial remote controller can remotely operate the tracked remote-controlled sludge dredging robot. The industrial remote controller has switch buttons and adjustment buttons corresponding to various functions.

[0031] Then, the tracked remote-controlled dredging robot is started using an industrial remote controller. The button turns on the visual self-cleaning underwater camera 4. At this time, the visual self-cleaning underwater camera 4 is used to observe the sludge at the bottom of the pool. The button then turns on the valve body of the high-pressure nozzle 7. The direction of water spray from the high-pressure nozzle 7 is adjusted by the extension and retraction of the output shaft on the first hydraulic cylinder 901. After the sludge is dispersed, the button turns on the valve body of the high-pressure nozzle 7. The angle of the bucket 10 is adjusted to fit the bottom of the vehicle by the extension and retraction of the output shaft on the second hydraulic cylinder 902. The button starts the sludge pump to extract sewage. The button then stops the sludge pump.

[0032] Subsequently, the button drives the gears in the track assembly 1 through the hydraulic motor 3 to adjust the robot's position and posture. Then, the valve body of the high-pressure nozzle 7 is opened. The spray direction of the high-pressure nozzle 7 is adjusted by the extension and retraction of the output shaft of the first hydraulic cylinder 901. After the sludge is dispersed, the valve body of the high-pressure nozzle 7 is closed. The output shaft of the second hydraulic cylinder 902 extends to adjust the angle of the bucket 10 to fit against the bottom of the vehicle. After the button starts the sludge pump to extract sewage, the button stops the sludge pump.

[0033] Secondly, during the above operation, the vehicle's all-around marker lights 5 remain on after the hoisting robot enters the sludge tank, and the toxic gas detection module 6 is also turned on. Once toxic gas is detected, the toxic gas detection module 6 will send a signal to the remote control.

[0034] Finally, the hydraulic motor 3 on the track assembly 1 controls the robot's forward, backward, turning, and U-turn movements. The first hydraulic cylinder 901 on the dredging mechanism controls the direction and angle of the water spray from the high-pressure nozzle 7, while the second hydraulic cylinder 902 controls the direction and angle of the bucket 10. The operator observes the position and state of the silt through the visual self-cleaning underwater camera 4 and uses the remote control to adjust the robot's posture, adjusting the direction and angle of the high-pressure nozzle 7 and the bucket 10 to clean the silt. After the silt is cleaned to a certain extent, the sludge pump is started to pump the silt out of the sludge pool and discharge it to the designated location. Then the sludge pump is stopped, and the high-pressure nozzle 7 is started again, and so on, until the silt is cleaned.

[0035] Furthermore, since the diameter of the filter holes on the second filter plate 13 is larger than that on the connecting pipe 11, the water before entering the high-pressure water pipe 8 will first pass through the connecting pipe 11. The water entering the connecting pipe 11 will first pass through the second filter plate 13 for the first filtration. The water after the first filtration will then flow to the first filter plate 12 for the second filtration. The impurities in the water will flow into the high-pressure water pipe 8 after being filtered twice, thus preventing the impurities in the water from clogging the high-pressure nozzle 7 with the flow of water.
