One end of each second spray head is connected to the first spray head. A high-pressure water pump is provided in the middle of the hanger. The output end of the high-pressure water pump is connected to a water inlet pipe. One end of the water inlet pipe is connected to an anti-clogging head. One end of the anti-clogging head is fixedly connected to a float. The output end of the high-pressure water pump is connected to a spray pipe. The bottom end of the spray pipe is connected to a three-way solenoid valve, and both ends of the three-way solenoid valve are respectively connected to the middle of the first spray head, which facilitates the dispersal of sludge and provides power for the movement of sludge.

[0007] Preferably, the control terminals of the high-pressure water pump and the three-way solenoid valve are both electrically connected to the controller via control sensors, which facilitates the automatic operation of the device.

[0008] Preferably, the sludge suction mechanism includes a sludge suction device. Side-cutting protective plates are fixedly connected to both sides of the sludge-shoveling block, and these plates are closely fitted together. Both ends of the side-cutting protective plates are beveled. A main pipe is installed at the top of the movable cross bridge, with one end of the main pipe being arc-shaped. A sludge suction device is installed in the middle of each hanger. A first motor is installed in the upper middle part of each hanger, and the output end of the first motor is connected to an auxiliary plate. The input end of each sludge suction device is connected to a suction pipe, and the output end of each sludge suction device is connected to a discharge pipe, with the top end of the discharge pipe connected to the main pipe. A rotating groove is opened in the middle of each sludge-shoveling block, and both ends of the rotating groove are connected to a sludge suction chamber. One side of each auxiliary plate forms a sludge chamber adjacent to the sludge suction chamber, used for mixing sludge and water. The interior of each sludge-collecting tank is rotatably connected to a suction head. The top of each suction head is connected to a connecting pipe, the top of which extends to the outside of the sludge-collecting block. The top of each connecting pipe is connected to a suction pipe via a rotary seal. Each sludge-collecting block has a power groove at its bottom. A rotating rod is fixedly connected to the bottom of each suction head, and the bottom of each rotating rod extends into the power groove. The bottom of each rotating rod is connected to the inner wall of the power groove bottom via a bearing. A worm gear is fixedly connected to the lower middle part of each rotating rod. A second motor is installed inside each power groove. A worm is fixedly connected to the output end of each second motor, and one end of each worm is connected to the inner wall of the power groove via a bearing. The worms mesh with the worm gears, enabling comprehensive suction of sludge from the sedimentation tank and improving cleaning efficiency.

[0009] Preferably, the control terminals of both the first motor and the second motor are electrically connected to the controller via control sensors, which facilitates the automatic operation of the device.

[0010] Preferably, the auxiliary mechanism includes auxiliary rollers, with auxiliary rollers provided at both ends of the sludge-shoveling block, and a third motor provided at both ends of the sludge-shoveling block. The output ends of the third motors are fixedly connected to one end of the auxiliary rollers, and the other ends of the auxiliary rollers are connected to the inner wall of the sludge-suction chamber via bearings. One side of each auxiliary plate forms an arc chamber with the inner wall at the top of the sludge-suction chamber. The auxiliary rollers are rotatably connected to the arc chambers. The surfaces of the auxiliary rollers are uniformly provided with collecting grooves. Dividing push plates are slidably connected inside each collecting groove, and one end of each dividing push plate is arc-shaped. Springs are uniformly fixedly connected to one end of each dividing push plate, and one end of each spring is fixedly connected to the inner wall of the collecting groove, which facilitates the dispersion and treatment of sludge and also promotes the movement of sludge.

[0011] Preferably, one side of each of the auxiliary plates is arc-shaped, and the arc shape is adapted to the arc of the dividing push plate, so that the dividing push plate can be moved into the inside of the receiving groove by means of the auxiliary plate. The control end of each of the third motors is electrically connected to the controller through the control sensor, so that the device can work automatically.

[0012] The operating method of this device is as follows: Step 1: Movement. The user controls the movement of this device through the controller. The speed is set according to the turbidity of the sewage. If the sewage is turbid, the movement speed of this device is reduced, and vice versa. The moving cross bridge, the hanging frame and the sludge shovel block are driven by the power track wheels to carry out sludge removal work inside the sedimentation tank. The sloping surfaces at the bottom of the suction chambers on both sides of the sludge shovel block can scrape up the sludge on the inner wall of the sedimentation tank. Step 2: Auxiliary, the third motor drives the auxiliary roller and the dividing push plate to rotate. The dividing push plate can cut the scraped sludge into segments, and at the same time can also drive the sludge to move into the interior of the sludge suction chamber. Step 3: Spraying. The high-pressure water pump can drive the clear water at the top of the sedimentation tank into the first and second spray heads through the spray pipe and the three-way solenoid valve. The water is sprayed onto the sludge through one end of the first and second spray heads. The second spray head can reduce the bottom of the sludge and disperse it, while the first spray head can disperse the top of the sludge. The first and second spray heads work together to not only disperse the sludge but also move the sludge water into the interior of the suction chamber. Step 4: Sludge suction. The first motor drives the sludge suction device to work. At this time, the bottom of the sludge suction device generates suction. The suction force is transmitted through the suction pipe and connecting pipe to generate suction at one end of the suction head. The flow rate generated by the first and second jet heads is much lower than the suction force generated on the side of the suction head opening. At the same time, the impact force of the first and second jet heads causes the sludge water to enter the discharge pipe and finally be discharged into the sludge collection tank through the main pipe for centralized collection. Step 5: Reverse suction. After the power track wheel moves the moving cross bridge, hanger, and sludge block to one end of the moving track and contacts the control sensor, the three-way solenoid valve controls the first and second spray heads at one end of the sludge block to close and the first and second spray heads at the other end to operate. The third motor and auxiliary roller at one end of the sludge block stop working while the auxiliary roller and third motor at the other end start working. At the same time, the second motor drives the worm gear to work, rotating 180 degrees through the worm wheel, rotating rod, and suction head, so that the opening of the suction head is inside another suction chamber. At this time, the power track wheel drives the moving cross bridge, hanger, and sludge block back to continue the suction operation.

[0013] Compared with the prior art, the beneficial effects of the present invention are: The user controls the device via a controller to perform suction operations. Its operating speed is 1 to 1.5 meters per minute. The specific moving speed is set according to the turbidity of the wastewater entering the sedimentation tank; it is not a fixed, single speed. If the wastewater is turbid and the sludge thickness is increased, the moving speed of the device is reduced; conversely, the moving speed is increased. Powered track wheels drive the moving crossbridge, hanger, and sludge-shoveling blocks to perform sludge removal work inside the sedimentation tank. Side-cutting protective plates ensure that the sludge moves towards both ends of the sludge-shoveling blocks, improving the sludge removal effect. The inclined surfaces at the bottom of the suction chambers on both sides of the sludge-shoveling blocks scrape up the sludge from the inner wall of the sedimentation tank. Simultaneously, a third motor drives auxiliary... The auxiliary roller and the dividing pusher rotate, cutting the scraped sludge into segments and moving it into the suction chamber. Simultaneously, a high-pressure water pump pumps clean water from the top of the sedimentation tank through a spray pipe and a three-way solenoid valve into the first and second spray heads. Water is sprayed onto the sludge from one end of each nozzle. The second spray head disperses the bottom of the sludge, while the first spray head disperses the top. The combined use of the first and second spray heads not only disperses the sludge but also moves the sludge-water mixture into the suction chamber. Meanwhile, the first motor drives the suction device, generating suction at its bottom. Suction is generated at one end of the suction head through the suction pipe and connecting pipe. At this time, a negative pressure is generated inside the suction chamber on the side of the suction head opening. The flow rate generated by the first and second jet heads is much lower than the suction force generated on the side of the suction head opening. At the same time, the impact force of the first and second jet heads causes the sludge water to enter the discharge pipe, preventing leakage. Finally, it is discharged into the sludge collection tank through the main pipe for centralized collection. When the power track wheel moves the moving cross bridge, the hanger, and the sludge shovel block to one end of the moving track, the power track wheel contacts the control sensor. At this time, the three-way solenoid valve controls the first and second jet heads at one end of the sludge shovel block to shut off, while the first and second jet heads at the other end of the sludge shovel block remain open. When the two spray heads are working, the third motor and auxiliary roller at one end of the sludge-shoveling block stop working, while the auxiliary roller and third motor at the other end of the sludge-shoveling block start working. At the same time, the second motor drives the worm gear to work, rotating the worm wheel, rotating rod, and suction head 180 degrees, so that the opening of the suction head is inside another suction chamber. At this time, the moving cross bridge, hanging frame, and sludge-shoveling block are driven back by the power track wheel, so as to continue the sludge suction work. This device can not only automatically perform sludge suction work, but also more comprehensively clean the sludge, improve the cleaning effect, avoid incomplete cleaning, and prevent the sludge from remaining in the sedimentation tank. It can also reduce the user's workload and provide great convenience for the user's sludge cleaning work. Attached Figure Description

A sludge suction chamber 11 is provided at both ends of the sludge scraping block 8. An auxiliary plate 12 is fixedly connected to the inner wall at the top of the sludge suction chamber 11. A spraying mechanism for dispersing sludge is provided at both ends of the sludge scraping block 8. A sludge suction mechanism for suctioning sludge is provided in the middle of the hanger 7 and the sludge scraping block 8. An auxiliary mechanism for assisting the movement of sludge is provided at both ends of the sludge scraping block 8. Please see Figures 4-6 In this embodiment, the spraying mechanism includes a first spray head 13. Both ends of the sludge-shoveling block 8 are provided with a first spray head 13, and the bottom ends of the first spray heads 13 pass through the auxiliary plate 12 and point towards the side of the suction chamber 11 that is close to each other. Both ends of the sludge-shoveling block 8 are symmetrically provided with second spray heads 14, and one end of each second spray head 14 points towards the side of the suction chamber 11 that is close to each other. One end of each second spray head 14 is connected to a first spray head 13. A high-pressure water pump 15 is provided in the middle of each hanger 7. The output end of each high-pressure water pump 15 is connected to a water inlet pipe 16. One end of each water inlet pipe 16 is connected to an anti-clogging head 17. One end of each anti-clogging head 17 is fixedly connected to a float 18. The output end of each high-pressure water pump 15 is connected to a spray pipe 19. The bottom end of each spray pipe 19 is connected to a three-way solenoid valve 20. Both ends of the solenoid valve 20 are connected to the middle of the first spray head 13. The float 18 allows the anti-clogging head 17 and the inlet pipe 16 to only draw in the upper layer of clear water. The anti-clogging head 17 can block impurities in the water. The high-pressure water pump 15 can drive the clear water at the top of the sedimentation tank 1 into the first spray head 13 and the second spray head 14 through the spray pipe 19 and the three-way solenoid valve 20. One end of the first spray head 13 and the second spray head 14 is sprayed towards the sludge. The second spray head 14 can reduce the bottom of the sludge from being dispersed. The first spray head 13 can disperse the top of the sludge. By using the first spray head 13 and the second spray head 14, which are pointing to the innermost part of the sludge suction chamber 11, not only can the sludge be dispersed, but the sludge water can also move into the interior of the sludge suction chamber 11, which facilitates the dispersion of the sludge and provides power for the movement of the sludge. Please see Figures 2-7In this embodiment, the sludge suction mechanism includes a sludge suction device 21. Side-cutting protective plates 9 are fixedly connected to both sides of the sludge-shoveling block 8, and the side-cutting protective plates 9 are closely fitted together. Both ends of the side-cutting protective plates 9 are beveled. A main pipe 10 is provided at the top of the movable cross bridge 3, and one end of the main pipe 10 is arc-shaped. A sludge suction device 21 is provided in the middle of each hanger 7. A first motor 22 is provided in the upper middle part of each hanger 7, and the output end of the first motor 22 is connected to the auxiliary plate 12. A sludge suction pipe 23 is connected to the input end of each sludge suction device 21, and a sludge discharge pipe 24 is connected to the output end of each sludge suction device 21. The top end of each sludge discharge pipe 24 is connected to the main pipe 10. A rotating groove 25 is opened in the middle of each sludge-shoveling block 8, and both ends of the rotating groove 25 are connected to the sludge suction chamber 11. One side of the auxiliary plate 12 forms a sludge chamber close to the end of the suction chamber 11, used for mixing sludge and water. Suction heads 26 are rotatably connected inside the rotating trough 25. The top of each suction head 26 is connected to a connecting pipe 27, which extends to the outside of the sludge-shoveling block 8. The top of each connecting pipe 27 is connected to the suction pipe 23 via a rotary seal. A power groove 28 is provided at the bottom of each sludge-shoveling block 8. A rotating rod 29 is fixedly connected to the bottom of each suction head 26, and the bottom of each rotating rod 29 extends into the power groove 28. The bottom of each rotating rod 29 is connected to the inner wall of the bottom of the power groove 28 via a bearing. A worm gear 30 is fixedly connected to the lower middle part of each rotating rod 29. A second motor 31 is installed inside each power groove 28. The output ends of the second motor 31 are all fixedly connected to worm gears 32, and one end of each worm gear 32 is connected to the inner wall of the power groove 28 through bearings. Each worm gear 32 meshes with a worm wheel 30. Since both ends of the side-cutting protective plate 9 are inclined, the side-cutting protective plate 9 can ensure that the sludge moves to both ends of the sludge-shoveling block 8, improving the sludge cleaning effect. The inclined surfaces at the bottom of the suction chambers 11 on both sides of the sludge-shoveling block 8 can scrape up the sludge on the inner wall of the sedimentation tank 1. The first motor 22 drives the suction device 21 to work. At this time, the bottom end of the suction device 21 generates suction. The suction through the suction pipe 23 and the connecting pipe 27 causes one end of the suction head 26 to generate suction. At this time, the suction chamber 11 on the open side of the suction head 26 generates suction, making the innermost side of the suction chamber 11 negative pressure. In this state, the first jet head 13 and the second jet head 14 generate a flow rate much lower than the suction force generated on the opening side of the suction head 26. Combined with the impact force of the first jet head 13 and the second jet head 14, the sludge water enters the discharge pipe 24, preventing leakage. Finally, it is discharged into the sludge collection tank 2 through the main pipe 10 for centralized collection. When the power track wheel 6 moves the moving cross bridge 3, the hanger 7 and the sludge shovel block 8 to one end of the moving track 4, the power track wheel 6 contacts the control sensor 38. At this time, the output end of the second motor 31 drives the worm gear 32 to rotate. The rotating worm gear 32 drives the worm wheel 30 to rotate. The rotating worm wheel 30 drives the suction head 26 to rotate 180 degrees through the rotating rod 29, so that the opening of the suction head 26 is inside another suction chamber 11.It can completely remove the sludge inside sedimentation tank 1, improving the cleaning effect; Please see Figure 7 and Figure 8 In this embodiment, the auxiliary mechanism includes auxiliary rollers 33. Both ends of the sludge-shoveling block 8 are equipped with auxiliary rollers 33, and both ends of the sludge-shoveling block 8 are equipped with third motors 34. The output ends of the third motors 34 are fixedly connected to one end of each auxiliary roller 33. The other ends of each auxiliary roller 33 are connected to the inner wall of the suction chamber 11 via bearings. One side of each auxiliary plate 12 forms an arc chamber with the inner wall at the top of the suction chamber 11. The auxiliary rollers 33 are rotatably connected to the arc chambers. The surface of each auxiliary roller 33 is uniformly provided with collecting grooves 35. Sliding push plates 36 are slidably connected inside each collecting groove 35. One end of each dividing push plate 36 is arc-shaped. Springs 37 are uniformly fixedly connected to one end of each dividing push plate 36. One end of each spring 37 is divided... The auxiliary roller 33 is rotated by the output end of the third motor 34, which drives the auxiliary roller 33 to rotate. The rotating auxiliary roller 33 drives the dividing push plate 36 to rotate. The dividing push plate 36 can cut the scraped sludge into segments and also move the sludge into the suction chamber 11. When the arc surface of one end of the dividing push plate 36 abuts against the arc surface of one side of the auxiliary plate 12, the dividing push plate 36 slides into the inside of the collection trough 35. The dividing push plate 36 can compress the connecting pipe 27. When one end of the dividing push plate 36 no longer abuts against the auxiliary plate 12 and the suction chamber 11, the dividing push plate 36 can be lowered under the action of the collection trough 35, which facilitates the dispersion and treatment of the sludge and can also push the sludge to move. It should be noted that a sludge collection tank 2 is provided on one side of the sedimentation tank 1, a controller 5 is provided at one end of the movable cross bridge 3, and powered track wheels 6 are symmetrically provided at both ends of the movable cross bridge 3, with the bottom ends of the powered track wheels 6 respectively abutting against the movable track 4. The bottom ends of the opposite sides of the suction chambers 11 are all inclined to facilitate the movement of sludge, while the sides of the suction chambers 11 that are close to each other are all funnel-shaped, and the inner walls of the tops of the opposite sides of the suction chambers 11 are all arc-shaped to facilitate the provision of a negative pressure environment. The control terminal of the controller 5 is electrically connected to an external power source, and the control terminals of the powered track wheels 6 are all electrically connected to the controller 5 through control sensors 38. To facilitate the operation of this device, the control terminals of the high-pressure water pump 15 and the three-way solenoid valve 20 are electrically connected to the controller 5 through the control sensor 38, which facilitates the automatic operation of this device. The control terminals of the first motor 22 and the second motor 31 are also electrically connected to the controller 5 through the control sensor 38, which facilitates the automatic operation of this device. One side of the auxiliary plate 12 is arc-shaped, and the arc shape is adapted to the arc of the dividing push plate 36, which facilitates the movement of the dividing push plate 36 into the inside of the receiving groove 35 through the auxiliary plate 12. The control terminal of the third motor 34 is also electrically connected to the controller 5 through the control sensor 38, which facilitates the automatic operation of this device. The device operates as follows: Step 1: Movement. The user controls the movement of this device through the controller 5. The speed is set according to the turbidity of the sewage. If the sewage is turbid, the movement speed of this device is reduced, and vice versa. The moving cross bridge 3, the hanging frame 7 and the sludge scraper 8 are driven by the power track wheel 6 to carry out sludge removal work inside the sedimentation tank 1. The sludge on the inner wall of the sedimentation tank 1 can be scraped up by the inclined surface at the bottom of the suction chamber 11 on both sides of the sludge scraper 8. Step 2: Assistance. The third motor 34 drives the auxiliary roller 33 and the dividing push plate 36 to rotate. The dividing push plate 36 can cut the scraped sludge into segments and also drive the sludge to move into the suction chamber 11. Step 3: Spraying. The high-pressure water pump 15 can drive the clear water at the top of the sedimentation tank 1 into the first spray head 13 and the second spray head 14 through the spray pipe 19 and the three-way solenoid valve 20. The water is sprayed onto the sludge through one end of the first spray head 13 and the second spray head 14. The second spray head 14 can reduce the bottom of the sludge and disperse it. The first spray head 13 can disperse the top of the sludge. The first spray head 13 and the second spray head 14 work together to not only disperse the sludge but also move the sludge water into the interior of the sludge suction chamber 11. Step 4: Sludge suction. The first motor 22 drives the sludge suction device 21 to work. At this time, the bottom of the sludge suction device 21 generates suction. The suction force is transmitted through the sludge suction pipe 23 and the connecting pipe 27 to generate suction at one end of the suction head 26. The flow rate generated by the first jet head 13 and the second jet head 14 is much lower than the suction force generated by the opening side of the suction head 26. At the same time, the impact force of the first jet head 13 and the second jet head 14 causes the sludge water to enter the discharge pipe 24 and finally discharge it into the sludge collection tank 2 through the main pipe 10 for centralized collection. Step 5: Reverse suction. When the power track wheel 6 moves the moving cross bridge 3, the hanger 7, and the sludge shovel 8 to one end of the moving track 4 and contacts the control sensor 38, the three-way solenoid valve 20 controls the first spray head 13 and the second spray head 14 at one end of the sludge shovel 8 to close and the first spray head 13 and the second spray head 14 at the other end to work. The third motor 34 and the auxiliary roller 33 at one end of the sludge shovel 8 stop working and the auxiliary roller 33 and the third motor 34 at the other end work. At the same time, the second motor 31 drives the worm gear 32 to work, and through the worm wheel 30, the rotating rod 29, and the suction head 26 to rotate 180 degrees, so that the opening of the suction head 26 is inside another suction chamber 11. At this time, the power track wheel 6 drives the moving cross bridge 3, the hanger 7, and the sludge shovel 8 to return and continue the suction work.

[0018] Working Principle: The user controls the device via controller 5 to perform suction operations. After a single sedimentation in sedimentation tank 1, the thickness difference of the settled sludge is not significant, preventing localized areas from having excessively thick or thin sludge. The operating speed is set according to the turbidity of the sewage, typically ranging from 1 meter to 1.5 meters per minute. If the sewage is turbid and the sludge thickness increases, the device's moving speed is reduced; conversely, the moving speed is increased. The moving crossbridge 3, hanger 7, and sludge shovel 8 are driven by the power track wheels 6 to perform sludge removal within sedimentation tank 1. Because both ends of the side-cutting protective plate 9 are beveled, it ensures that the sludge moves towards both ends of the sludge shovel 8, improving the sludge removal effect. The inclined surfaces at the bottom of the suction chambers 11 on both sides of the sludge scraper block 8 can scrape up the sludge from the inner wall of the sedimentation tank 1. At the same time, the output end of the third motor 34 drives the auxiliary roller 33 to rotate. The rotating auxiliary roller 33 drives the dividing push plate 36 to rotate. The dividing push plate 36 can cut the scraped sludge into segments and also move the sludge into the suction chamber 11. When the arc surface of one end of the dividing push plate 36 abuts against the arc surface of one side of the auxiliary plate 12, the dividing push plate 36 slides into the collection trough 35. The dividing push plate 36 can compress the connecting pipe 27. When one end of the dividing push plate 36 no longer abuts against the auxiliary plate 12 and the suction chamber 11, the dividing push plate 36 can be lowered and ejected under the action of the collection trough 35. 18 allows the anti-clogging head 17 and inlet pipe 16 to only draw in the upper layer of clear water. The anti-clogging head 17 can block impurities in the water. The high-pressure water pump 15 can drive the clear water from the top of the sedimentation tank 1 through the spray pipe 19 and the three-way solenoid valve 20 into the first spray head 13 and the second spray head 14. One end of the first spray head 13 and the second spray head 14 is sprayed towards the sludge. The second spray head 14 can reduce the bottom of the sludge from being dispersed, while the first spray head 13 can disperse the top of the sludge. The first spray head 13 and the second spray head 14 can only drain water; sludge will not enter the interior of the first spray head 13 and the second spray head 14. By using the first spray head 13 and the second spray head 14, which are pointed to the innermost part of the sludge suction chamber 11, it can not only remove sludge but also... The flushing action also allows the sludge-water to move into the suction chamber 11. Simultaneously, the first motor 22 drives the suction device 21 to operate, generating suction at the bottom of the suction device 21. This suction, through the suction pipe 23 and connecting pipe 27, causes one end of the suction head 26 to generate suction, creating a suction inside the suction chamber 11 on the open side of the suction head 26. This creates a negative pressure state at the innermost part of the suction chamber 11. At the same time, the flow rate generated by the first jet head 13 and the second jet head 14 is much lower than the suction generated on the open side of the suction head 26. Combined with the impact force of the first jet head 13 and the second jet head 14, the sludge-water enters the discharge pipe 24, preventing leakage. Finally, it is discharged into the sludge collection tank 2 through the main pipe 10 for centralized collection. One end of the main pipe 10 is arc-shaped.To facilitate the accurate discharge of the sludge and water mixture into the sludge collection tank 2, and because the main pipeline 10 has a very large hourly drainage capacity, its arc-shaped section will not generate eddies or cause blockages. When the power track wheel 6 moves the moving cross bridge 3, the hanger 7, and the sludge shovel block 8 to one end of the moving track 4, the power track wheel 6 contacts the control sensor 38. At this time, the three-way solenoid valve 20 controls the first spray head 13 and the second spray head 14 at one end of the sludge shovel block 8 to shut down, while the first spray head 13 and the second spray head 14 at the other end of the sludge shovel block 8 operate. The third motor 34 and the auxiliary roller 33 at one end of the sludge shovel block 8 stop operating, while the auxiliary roller 33 and the third motor 34 at the other end of the sludge shovel block 8 operate. Simultaneously, the output end of the second motor 31 drives the worm gear 32 to rotate, and the rotating worm gear 32 drives the worm wheel 30 to rotate. The rotating worm wheel 30 drives the suction head 26 to rotate 180 degrees through the rotating rod 29, so that the opening of the suction head 26 is in another suction position. Inside the sludge chamber 11, the moving crossbridge 3, hanger 7, and sludge shovel 8 are driven back by the power track wheel 6, thus continuing the sludge suction work. The sludge particles inside the sedimentation tank 1 are relatively small and usually do not cause blockage of the suction pipe 23 and discharge pipe 24. Even if a slight blockage occurs, the user can place clean water at the end of the main pipe 10 and then control the suction device 21 to work in reverse to perform backwashing, discharging the blocked portion. After normal sludge suction is completed, the device needs to be stopped after a three- to five-minute delay. This delay allows the clean water inside the sedimentation tank 1 to flush the suction pipe 23 and discharge pipe 24, thoroughly cleaning the sludge inside. This device not only automatically performs sludge suction but also cleans the sludge more comprehensively, improving the cleaning effect and preventing incomplete cleaning that could lead to sludge remaining inside the sedimentation tank 1. It also reduces the user's workload and provides great convenience for sludge removal.

9. A method for operating the bridge-type scraper-suction sludge device as described in claim 8, characterized in that: Step 1: Movement. The user controls the movement of this device through the controller (5). The speed is set according to the turbidity of the sewage. If the sewage is turbid, the movement speed of this device is reduced, and vice versa. The moving cross bridge (3), the hanging frame (7) and the shovel block (8) are driven by the power track wheel (6) to carry out sludge removal work inside the sedimentation tank (1). The sludge on the inner wall of the sedimentation tank (1) can be scraped up by the inclined surface at the bottom of the suction chamber (11) on both sides of the shovel block (8). Step 2: Assistance. The third motor (34) drives the auxiliary roller (33) and the dividing push plate (36) to rotate. The dividing push plate (36) can cut the scraped sludge into segments and also drive the sludge to move into the sludge suction chamber (11). Step 3: Spraying. The high-pressure water pump (15) can spray the clear water at the top of the sedimentation tank (1) into the first spray head (13) and the second spray head (14) through the spray pipe (19) and the three-way solenoid valve (20). The water is sprayed onto the sludge through one end of the first spray head (13) and the second spray head (14). The second spray head (14) can reduce the bottom of the sludge and disperse it. The first spray head (13) can disperse the top of the sludge.

The first motor (22) drives the suction device (21) to work. At this time, the bottom of the suction device (21) generates suction. The suction force is transmitted through the suction pipe (23) and the connecting pipe (27) to generate suction at one end of the suction head (26). The first jet head (13) and the second jet head (14) generate a flow rate much lower than the suction force generated on the side of the opening of the suction head (26).

Step 5: Reverse suction. When the power track wheel (6) drives the moving cross bridge (3), the hanger (7) and the shovel block (8) to one end of the moving track (4) and contact the control sensor (38), the three-way solenoid valve (20) controls the first spray head (13) and the second spray head (14) at one end of the shovel block (8) to close and the first spray head (13) and the second spray head (14) at the other end to work. The third motor (34) and the auxiliary roller (33) at one end of the shovel block (8) stop working and the auxiliary roller (33) and the third motor (34) at the other end work. At the same time, the second motor (31) drives the worm (32) to work. Through the worm wheel (30), the rotating rod (29) and the suction head (26) rotate 180 degrees, so that the opening of the suction head (26) is inside another suction chamber (11). At this time, the power track wheel (6) drives the moving cross bridge (3), the hanger (7) and the shovel block (8) to return and continue the suction work.
