It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit 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.

[0040] Example 1, please refer to Figures 1 to 19This invention provides a technical solution: a tracked drainage robot for cleaning urban drainage outlets, comprising a body 1, characterized in that: an engine 2 is fixedly installed on the inner wall of the body 1; a suspension 3 is fixedly connected to the bottom outer wall of the body 1; a water pump 4 is fixedly installed on the top outer wall of the suspension 3; an obstacle avoidance groove 5 penetrating the water pump 4 is opened on the bottom outer wall of the suspension 3; a hydraulic pump base 6 is fixedly installed on the bottom outer wall of the water pump 4; the four outer walls of the hydraulic pump base 6 are fixedly installed to the inner wall of the obstacle avoidance groove 5; a hydraulic rod 7 is fixedly installed on the bottom outer wall of the hydraulic pump base 6; and an upper ring plate is fixedly connected to the outer wall of the end of the hydraulic rod 7 away from the hydraulic pump base 6. 43.

A central control box 42 is fixedly installed on one side outer wall of the body 1. A hydraulic rod 9 is fixedly installed on the bottom outer wall of the hydraulic pump base 6. A through hole is opened in the upper ring plate 43. A lower ring plate 10 is fixedly connected to one end of the outer wall of the hydraulic rod 9 through the through hole. The top outer wall of the lower ring plate 10 is movably fitted with the bottom outer wall of the upper ring plate 43. An outer screen 11 is fixedly installed on the inner wall of the lower ring plate 10. A protective net 12 is fixedly installed on the top outer wall of the outer screen 11.

[0041] Traditional tracked robots pump water from their undercarriage, above ground level. In cities with sewer outlets located in low-lying areas, this makes pumping water from these areas difficult. In this invention, the robot is remotely driven to the sewer outlet. Workers connect a drainage hose to the pump 4 and start it to pump water from the spring hose 8. The length of the spring hose 8 can be adjusted by driving hydraulic rods 7 and 9, allowing the pumping position to be extended to lower areas, thus achieving adaptive pumping height. Simultaneously, aligning the pumping port of the spring hose 8 with the sewer outlet allows the high-pressure suction to lift lightweight debris blocking the outlet, relieving blockage and aiding in cleaning. This improves drainage efficiency and enhances the overall drainage system.

[0042] In Example 2, based on Example 1, an inner screen 13 is movably connected to the inner wall of the protective net 12. Four semi-circular arc-shaped positioning plates 14 are formed on the outer wall of the inner screen 13, arranged in an array around the inner screen 13. Arc-shaped positioning grooves 15 are formed on the bottom outer wall of each arc-shaped positioning groove 15, and clamping teeth 16 are slidably engaged on the inner wall of each groove. A second positioning plate 19 is fixedly installed at the center of the inner screen 13. A central positioning tooth 17 is fixedly installed on the bottom outer wall of the second positioning plate 19, and a threaded groove 18 is formed on the outer wall of the central positioning tooth 17. A retainer 20 is fixedly installed on the top outer wall of the outer screen 11, and a pressure plate 21 is fixedly installed at the center of the retainer 20. A limit rod 22 is fixedly installed on the bottom outer wall of the pressure plate 21. The top outer wall of the second positioning plate 19 is provided with a groove that engages with the threaded groove 18. The anti-detachment hole 44 is connected, and the inner wall of the anti-detachment hole 44 is movably fitted with the outer wall of the limiting rod 22. The bottom outer wall of the threaded groove 18 is provided with a pressure relief hole 45 connected with the anti-detachment hole 44. The outer wall of the limiting rod 22 is fitted with a return spring 23. The top outer wall of the return spring 23 abuts against the bottom outer wall of the pressure plate 21. The bottom outer wall of the return spring 23 abuts against the top outer wall of the positioning plate 29. The center position of the outer screen 11 is fixedly installed with a positioning plate 1 24. The top outer wall of the positioning plate 1 24 is provided with a through hole 25 connected with the bottom outer wall. The inner wall of the through hole 25 is threadedly fitted with the outer wall of the threaded groove 18. The outer wall of the outer screen 11 is provided with four straight vertical positioning grooves 26. The four vertical positioning grooves 26 are arranged in an array with the positioning plate 1 24 as the axis. The inner wall of the vertical positioning groove 26 is slidably engaged with the outer wall of the clamping tooth 16.

[0043] When the suction port of the spring hose 8 is aligned with the sewer opening, it sucks up some of the lightweight waste blocking the sewer opening. The lightweight waste then accumulates back and blocks the suction port of the spring hose 8. At this point, the spring hose 8 is returned to the position of the obstacle avoidance groove 5. Then, the spring hose 8 is contracted by adjusting the hydraulic rod 7, while the hydraulic rod 9 remains at a fixed length. At this time, the protective net 12 will be exposed inside the spring hose 8, and the lightweight waste is pressed under the outer screen 11. It is difficult for the waste to scatter and drift due to the obstruction of multiple clamping teeth 16. Meanwhile, the surrounding water flows into the spring hose 8 through the gaps in the protective net 12, ensuring normal water flow when suctioning lightweight waste and avoiding affecting drainage efficiency.

[0044] In Example 3, based on Example 1, a collection box 27 is fixedly installed on one side of the outer wall of the suspension 3. A connecting opening 28 is provided on the outer wall of the collection box 27 facing the obstacle avoidance groove 5. A net 29 is provided on the bottom inner wall of the collection box 27. Vertical racks 30 are fixedly installed on both sides of the outer wall of the net 29. Movable grooves 31 are provided on both sides of the bottom outer wall of the suspension 3. The inner walls of the two movable grooves 31 are slidably connected to the outer walls of the vertical racks 30. A reciprocating motor 32 is fixedly installed on the inner wall of the suspension 3. A gear 33 is fixedly installed on the shaft of the reciprocating motor 32. The outer wall of the gear 33 meshes with the outer wall of the movable groove 31. A row of shovel teeth 34 is fixedly connected to the top outer wall of the net 29. The center of the top outer wall of the net 29 is... A limiting plate 35 is fixedly installed, with the top outer wall of the limiting plate 35 pressing against the bottom outer wall of the center positioning tooth 17. An electrically controlled guide rail 36 is fixedly installed on the inner wall of the collection box 27 above the connecting port 28. An electrically controlled control 37 is electrically slidable on the outer wall of the electrically controlled guide rail 36. A baffle 38 is fixedly installed on the bottom outer wall of the electrically controlled control 37. The position of the baffle 38 is staggered with the position of the shovel tooth 34. A discharge port communicating with the inner wall is opened on one outer wall of the collection box 27. A discharge plate 39 is movably engaged on the outer wall of the discharge port. A closing motor 46 is fixedly installed on one outer wall of the collection box 27. A closing connecting rod 47 is fixedly installed on the shaft of the closing motor 46. One outer wall of the closing connecting rod 47 is fixedly connected to one outer wall of the discharge plate 39.

[0045] In this invention, the reciprocating motor 32 is started to drive the gear 33 to rotate. The meshing of the gear 33 with the vertical rack 30 allows the vertical rack 30 and the net 29 to slide within the movable chute 31. When the spring hose 8's suction port absorbs lightweight waste, the spring hose 8 is retracted into the obstacle avoidance groove 5. At this time, the reciprocating motor 32 is started to move the net 29 from the collection box 27 to the front of the lower ring plate 10. The hydraulic rod 29 drives the lower ring plate 10 to press the lightweight waste against the rear side of the net 29's panel. Then, the reciprocating motor 32 is started again. The reciprocating motor 32 drives the mesh 29 to move back. Since the latter half of the limiting plate 35 on the mesh 29 is sloped, the displacement of the limiting plate 35 will press against the central positioning tooth 17, causing the central positioning tooth 17 to move upwards. Simultaneously, the central positioning tooth 17 moves upwards through the threaded groove 18 and the through hole 25, causing the central positioning tooth 17 and the inner screen 13 to rotate synchronously. Furthermore, due to the rotation of the inner screen 13's threads, multiple clamping teeth 16 move spirally along the arc-shaped positioning groove 15. Simultaneously, the clamping teeth 16 will move linearly within the vertical positioning groove 26, with multiple clamping teeth 16 converging towards the center of the axis, tightening and clamping the lightweight waste under the outer screen 11 for easy subsequent gripping. As the slope of the limiting plate 35 increases, the central positioning tooth 17 is fully pushed into the through hole 25. At this point, the shovel tooth 34 has moved below the outer screen 11. The displacement of the shovel tooth 34 will shovel off the waste attached to the outer screen 11 and prevent the waste from detaching, until the electronic control 37 moves upward to lift the baffle 38 and lift the net 29. The waste is completely recycled into the collection box 27, and then the lower baffle 38 blocks the connection port 28, thus completing the cleaning of the blockage at the water outlet of the spring hose 8. Furthermore, when the scoop net 29 moves outward next time, the baffle 38 can block the waste scooped up by the shovel teeth 34 into the collection box 27 for easy collection. The inner screen 13 is reset under the pressure of the return spring 23. In this way, the collection and cleaning of light waste is completed, which helps to unclog the city's sewer outlets while assisting in drainage, thereby improving the efficiency of urban drainage.

[0046] The working principle and usage process of this invention: Traditional tracked robots have their pumping position located at the lower chassis, above the ground. If a city's sewer outlet is located in a low-lying area, lower than the surrounding road surface, it becomes difficult to pump water from that area. In this invention, the robot is remotely driven to the sewer outlet. Workers connect a drain hose to the pump 4 and start it to pump water from the spring hose 8. By driving hydraulic rods 7 and 9, the length of the spring hose 8 can be adjusted. This extension of the spring hose 8 allows the pumping position to be extended to the low-lying area, achieving adaptive pumping height. Simultaneously, by aligning the pumping port of the spring hose 8 with the sewer outlet, the high-pressure suction can remove some lightweight debris blocking the sewer outlet. The suction lifts up lightweight waste from the sewer opening, reducing sewer blockage and aiding in cleaning, thereby improving drainage efficiency and enhancing the drainage method. When the suction port of the spring hose 8 is aligned with the sewer opening, it sucks up some lightweight waste blocking the sewer opening. The lightweight waste then accumulates back and blocks the suction port of the spring hose 8. At this point, the spring hose 8 is returned to the position of the obstacle avoidance groove 5, and the spring hose 8 is contracted by adjusting the first hydraulic rod 7, while the second hydraulic rod 9 remains at a fixed length. At this time, the protective net 12 will be exposed inside the spring hose 8, and the lightweight waste is pressed under the outer screen 11. It is difficult for the waste to scatter and drift due to the obstruction of multiple clamping teeth 16, while the surrounding water flows into the spring hose 8 through the gaps in the protective net 12, ensuring the correct flow of water when suctioning lightweight waste. To ensure continuous flow and avoid affecting drainage efficiency, this invention uses a reciprocating motor 32 to drive a gear 33 to rotate. The meshing of the gear 33 with the vertical rack 30 allows the vertical rack 30 and the net 29 to slide within the movable chute 31. When the spring hose 8's suction port absorbs lightweight waste, the spring hose 8 retracts into the obstacle avoidance groove 5. At this point, the reciprocating motor 32 is activated, moving the net 29 from the collection box 27 to the front of the lower ring plate 10. The hydraulic rod 29 then drives the lower ring plate 10 to press the lightweight waste against the rear side of the net 29's panel. The reciprocating motor 32 is then activated again, causing the net 29 to move back. Since the latter half of the limiting strip 35 on the net 29 is a slope design, the displacement of the limiting strip 35 will press against the central positioning tooth 17, causing... The central positioning tooth 17 moves upward. Simultaneously, the central positioning tooth 17 and the inner screen 13 rotate and move upward in sync through the threaded groove 18 and through hole 25. Furthermore, due to the rotation of the inner screen 13's threads, multiple clamping teeth 16 spirally move within the arc-shaped positioning groove 15. At the same time, the clamping teeth 16 move linearly within the vertical positioning groove 26, converging towards the central axis to clamp and tighten the lightweight waste under the outer screen 11, facilitating subsequent gripping. As the slope of the limiting strip 35 increases, the central positioning tooth 17 is fully pushed into the through hole 25. At this point, the shovel tooth 34 has moved below the outer screen 11. The displacement of the shovel tooth 34 shovels off the waste attached to the outer screen 11 and prevents the waste from detaching.Until the electronic control 37 moves upward, lifting the baffle 38 and completely retracting the net 29 into the collection box 27, the lower baffle 38 then blocks the connecting port 28, thus completing the cleaning of the blockage debris at the water inlet of the spring hose 8. Furthermore, the next time the net 29 moves outward, the baffle 38 can block the debris scooped up by the shovel teeth 34 within the collection box 27 for easy collection. Meanwhile, the inner screen 13 resets under the pressure of the return spring 23. This method completes the collection and cleaning of lightweight waste, assisting in drainage while helping to unclog urban sewer inlets, thereby improving urban drainage efficiency.
