[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Example 1, by Figures 1 to 5The present invention discloses an integrated sewage lifting pump station comprising a cylindrical body 1, a sewage inlet pipe 2 disposed at the middle position of one side of the cylindrical body 1, a sewage outlet pipe 3 disposed at the top of the other side of the cylindrical body 1, a concrete support base 4 disposed at the bottom of the cylindrical body 1, a support frame 5 fixedly disposed at the top of the cylindrical body 1, a traction mechanism 6 disposed on one side of the top of the support frame 5, a traction mechanism 7 disposed on the other side of the top of the support frame 5, a manual passage 8 opened at the top of the cylindrical body 1 near the support frame 5, a ladder 9 fixedly disposed on one side inside the manual passage 8, and a support platform 10 disposed at the top of the interior of the cylindrical body 1. A support column 11 is provided at the middle position of the bottom of the support platform 10. A drive motor 12 is fixedly installed at the bottom inside the support column 11. A rotating shaft 13 is provided on the output shaft of the drive motor 12. A sewage sedimentation tank 14 is fixedly connected to the rotating shaft 13 at the bottom inside the cylinder 1. A floating garbage cleaning mechanism 15 is provided on one side inside the cylinder 1, which matches the sewage inlet pipe 2 and is connected to the first traction mechanism 6. A hanger 16 is provided on the other side inside the cylinder 1, which is connected to the second traction mechanism 7. A sludge removal and drainage integrated mechanism 17 matching the sewage sedimentation tank 14 is provided inside the hanger 16.

[0029] Wastewater is discharged into the interior of cylinder 1 through wastewater inlet pipe 2. At this time, floating debris cleaning mechanism 15 is located on one side of wastewater inlet pipe 2. Wastewater is first discharged into the interior of floating debris cleaning mechanism 15. Floating debris in the wastewater is filtered through floating debris cleaning mechanism 15 and remains inside floating debris cleaning mechanism 15. When there is a large accumulation of floating debris inside floating debris cleaning mechanism 15, floating debris cleaning mechanism 15 is lifted by traction mechanism 6. Then, the floating debris can be cleaned manually. Wastewater is discharged into the interior of wastewater sedimentation tank 14 through floating debris cleaning mechanism 15. Wastewater is treated by sedimentation in wastewater sedimentation tank 14, causing the sludge in the wastewater to settle. After sedimentation, the wastewater is drained and sludge is removed by integrated sludge removal and drainage mechanism 17.

[0030] Example 2, by Figures 1 to 4As shown, a through hole 18 matching the floating garbage cleaning mechanism 15 and the traction mechanism 6 is provided on one side of the top of the cylinder 1, and a through hole 29 matching the traction mechanism 7 is provided on the other side of the top of the cylinder 1. The traction mechanism 6 and the traction mechanism 7 are both composed of a servo motor 20, a rope wheel 21 and a traction rope 22. The servo motor 20 is fixedly connected to the top of the support frame 5, the rope wheel 21 is fixedly connected to the output shaft of the servo motor 20, and the traction rope 22 is connected to the rope wheel 21 and passes through the through hole 18 and the through hole 29. The support platform 10 is provided with a placement hole 1 23, a placement hole 24 and a placement hole 3 25. The placement hole 1 23 is fixedly provided with a limiting guide rail 1 26 matching the floating garbage cleaning mechanism 15. The placement hole 3 25 is provided with a limiting guide rail 27 matching the dredging and drainage integrated mechanism 17. The placement hole 2 24 has the same inner diameter as the manual channel 8.

[0031] When it is necessary to lift the floating garbage cleaning mechanism 15 and the integrated dredging and drainage mechanism 17, the corresponding traction mechanism 1 6 and traction mechanism 2 7 are activated. When traction mechanism 1 6 and traction mechanism 2 7 are working, the servo motor 20 drives the rope wheel 21 to rotate. The contraction of the traction rope 22 by the rope wheel 21 can drive the floating garbage cleaning mechanism 15 and the integrated dredging and drainage mechanism 17 to rise. The release of the traction rope 22 by the rope wheel 21 can drive the floating garbage cleaning mechanism 15 and the integrated dredging and drainage mechanism 17 to descend. During the process of lifting and lowering the floating garbage cleaning mechanism 15 and the integrated dredging and drainage mechanism 17, the limit guide rail 1 26 and the limit guide rail 2 27 are used to limit them respectively to prevent deviation during the lifting and lowering process, effectively improving their stability.

[0032] Example 3, by Figure 1 , Figure 2 and Figure 5 As shown, the sewage sedimentation tank 14 is provided with a partition plate 28 inside. A slot 29 matching the rotating shaft 13 is opened at the middle position of the top of the partition plate 28. The partition plate 28 and the sewage sedimentation tank 14 form a first sedimentation tank 30, a second sedimentation tank 31, a third sedimentation tank 32 and a fourth sedimentation tank 33. The side of the bottom end of the sewage sedimentation tank 14 and the side of the bottom end of the inner cylinder 1 are provided with annular limiting grooves 34. Several movable balls 35 are provided inside the annular limiting grooves 34.

[0033] When sewage enters the sewage sedimentation tank 14 for sedimentation, it first enters the first sedimentation tank 30. When the sewage inside the first sedimentation tank 30 is full, the sewage sedimentation tank 14 is rotated by the drive motor 12 and the rotating shaft 13, so that the first sedimentation tank 30 moves to the position of the second sedimentation tank 31, the fourth sedimentation tank 33 moves to the position of the first sedimentation tank 30, and so on. At this time, the sewage and sludge inside the second sedimentation tank 31 and the third sedimentation tank 32 are treated separately by the integrated sludge removal and drainage mechanism 17. During the rotation of the cylinder 1, the bottom of the cylinder can be moved and supported by the movable ball bearings 35, which can effectively improve its mobility and avoid friction.

[0034] Example 4, by Figure 1 , Figure 2 and Figure 6 The floating garbage cleaning mechanism 15 is composed of a receiving bucket 36, a conical section 37, a drainage inclined pipe 38, and a filter plate 39. The conical section 37 is fixedly connected to the bottom end of the receiving bucket 36, the drainage inclined pipe 38 is fixedly connected to the bottom end of the conical section 37, and the filter plate 39 is fixedly connected to the bottom end inside the receiving bucket 36. A water inlet slot 40 matching the sewage inlet pipe 2 is opened at the top of one side of the receiving bucket 36, and a detachable cleaning cover plate 41 is provided on the side of the receiving bucket 36 away from the water inlet slot 40.

[0035] After the sewage enters the receiving tank 36 through the inlet trough 40, it is filtered by the filter plate 39 to remove floating debris. The floating debris remains at the top of the filter plate 39, while the sewage penetrates the filter plate 39 and enters the conical section 37 and the interior of the drainage inclined pipe 38. The sewage is then discharged into the sewage sedimentation tank 14 through the drainage inclined pipe 38. When the drainage inclined pipe 38 is draining water, the outlet of the drainage inclined pipe 38 is close to the inner wall of the sewage sedimentation tank 14, so that the sewage falls along the sewage sedimentation tank 14, avoiding direct impact that increases the turbidity of the sewage and improving the sedimentation speed, thereby improving the sewage treatment efficiency. After the floating debris cleaning mechanism 15 rises, the removable cleaning cover 41 can be manually opened to clean the floating debris at the top of the filter plate 39.

[0036] Example 5, by Figure 1 , Figure 2 and Figure 7The integrated dredging and drainage mechanism 17 is composed of a dredging pump 42, a sewage lift pump 43, a sludge suction pipe 44, a sludge discharge pipe 45, a sewage suction pipe 46, a sewage discharge pipe 47, and a hose 48. The dredging pump 42 and the sewage lift pump 43 are both fixedly connected to the inside of the hanger 16. The sludge suction pipe 44 is fixedly connected to the bottom end of the dredging pump 42. The sludge discharge pipe 45 is fixedly connected to the top end of the dredging pump 42. The sewage suction pipe 46 is fixedly connected to the bottom end of the sewage lift pump 43. The sewage discharge pipe 47 is fixedly connected to the top end of the sewage lift pump 43. The hose 48 is connected between the sewage discharge pipe 47 and the sewage drain pipe 3. A return flushing pipe 49 is fixedly installed on one side of the sewage discharge pipe 47. A solenoid valve 50 is installed on the return flushing pipe 49. An annular water pipe 51 is fixedly installed on the end of the return flushing pipe 49 near the sludge suction pipe 44. Several flushing nozzles 52 are installed at the bottom end of the annular water pipe 51.

[0037] When the first sedimentation tank 30 receives wastewater, the second sedimentation tank 31 is in the sedimentation state, the third sedimentation tank 32 is in the wastewater discharge state, and the fourth sedimentation tank 33 is in the sludge discharge state. The wastewater sedimentation tank 14 rotates 90° each time, thus enabling continuous and uninterrupted sedimentation, wastewater discharge, and sludge discharge operations. Furthermore, each time the wastewater sedimentation tank 14 rotates, the traction mechanism 2 7 lifts the integrated sludge removal and drainage mechanism 17 once, preventing the integrated sludge removal and drainage mechanism 17 from obstructing the rotation of the wastewater sedimentation tank 14, effectively improving wastewater treatment efficiency. When removing sewage, the sewage lift pump 43 is started, and sewage is drawn through the sewage suction pipe 46. The sewage is discharged to the sewage drain pipe 3 through the sewage discharge pipe 47 and the hose 48. When removing sludge, the sludge removal pump 42 is started, and sludge is drawn through the sludge suction pipe 44 and discharged through the sludge discharge pipe 45. During sludge removal, the solenoid valve 50 is opened, and sewage is discharged to the annular water pipe 51 through the return flushing pipe 49. Then, the sedimentation tank being dredged is flushed through the flushing nozzle 52, which effectively improves the sludge removal effect and also improves the cleanliness of the sedimentation tank after sludge removal.

[0038] During operation, the system is equipped with a cylinder, traction mechanism one, traction mechanism two, drive motor, rotating shaft, sewage sedimentation tank, floating debris cleaning mechanism, and integrated dredging and drainage mechanism. It can first clean the floating debris inside the sewage, achieve sewage circulation sedimentation, and remove the settled sludge. The cleaning process can also flush the sewage sedimentation tank, effectively preventing blockage of the pump station and sewage pipes. At the same time, it can achieve continuous sewage lifting without interruption of the sewage lifting process, effectively improving the efficiency of sewage treatment.
