[0031] Reference Figure 1-Figure 5According to an embodiment of the utility model, an integrated pump station that is easy to maintain includes a pump station 11, a pump chamber 12 is provided in the pump station 11, a water inlet pipe 13 extending into the pump chamber 12 is installed in the pump station 11, a downwardly extending curved pipe 14 is installed at the end of the water inlet pipe 13, a filter assembly is provided in the curved pipe 14 so that the water entering the pump chamber 12 can be filtered, a water pump 26 is also provided in the pump chamber 12, and a water outlet pipe 27 extending outward and connected to the output end of the water pump 26 is installed in the pump station 11.

[0032] The filter assembly includes a sleeve 21 disposed in the curved pipe 14 . The sleeve 21 is provided with a water filter hole extending vertically therethrough, and a filter 22 is installed in the water filter hole. A convex plate 23 for supporting the sleeve 21 is provided in the curved pipe 14 .

[0033] In the second embodiment of the filter assembly, in order to enable the filter assembly to enter and exit the pump chamber 12, an inlet and outlet 24 that penetrates inside and outside and extends upward is provided in the curved pipe 14, and a rope 25 that passes through the inlet and outlet 24 is connected to the pump station 11 through a lifting assembly 101, and a clamp 102 for locking the sleeve 21 is installed at the end of the rope 25.

[0034] The diameter of the upper edge of the outer curved surface of the sleeve 21 is reduced to form a small diameter portion 28, and a hook ring 29 is provided on the curved surface of the small diameter portion 28. The clamp 102 includes a ring 31, and a plurality of hook plates 32 capable of abutting against the lower side of the hook ring 29 are hinged on the inner curved surface of the ring 31. The upper side of the hook plate 32 is connected to the inner curved surface of the ring 31 through a spring, and the hook plate 32 can abut against the lower side of the ring 31 to maintain a parallel state. The end of the rope 25 is connected to the ring 31. During the downward movement of the ring 31, the ring 31 can pass through the inlet and outlet 24 and enter the curved pipe 14. After the hook plate 32 in the ring 31 moves to the lower side of the hook ring 29, the hook plate 32 pops out under the action of the spring, and then the rope 25 is retracted upward. At this time, the hook plate 32 abuts against the lower side of the hook ring 29 and can lift the sleeve 21 upward, and the sleeve 21 can leave the curved pipe 14 through the inlet and outlet 24 for cleaning.

[0035] After the curved pipe 14 is cleaned, the staff can put the sleeve 21 back into the curved pipe 14 through the rope 25 and make it abut against the convex plate 23. At this time, the sleeve 21 is cleaned.

[0036] In this embodiment, in order to ensure stable lifting and lowering of the sleeve 21 , a plurality of rope rings 41 are provided at equal angles on the upper side surface of the sleeve 21 with the axis of the sleeve 21 as the center, and the rope 25 is decomposed into several rope strands and connected to each of the rope rings 41 .

[0037] In the third embodiment of the filter assembly, in order to improve the filtering effect, a plurality of filter assemblies stacked up and down are arranged in the curved pipe 14. In addition, in this embodiment, in order to enable the clamp 102 to be separated from the sleeve 21 after the sleeve 21 is placed in the curved pipe 14, an electromagnet 37 for attracting the hook plate 32 and allowing it to stick to the inner curved surface of the ring 31 is also provided in the ring 31. After the sleeve 21 is placed in place, the electromagnet 37 can be energized to attract the hook plate 32, and then the rope 25 pulls the ring 31 upward, and in this process the ring 31 can leave the placed sleeve 21, and other filter assemblies are stacked. In order to enable the sleeve 21 to be stacked up and down, the lower edge of the diameter of the water filter hole is narrowed.

[0038] In addition, in order to prevent the water from overflowing through the inlet and outlet 24 when water flows into the water inlet pipe 13, a closing plate 34 for closing the inlet and outlet 24 is provided on the rope 25, and the bent pipe 14 is provided with an electric cylinder 35, and a locking block 36 for locking the closing plate 34 is installed on the output shaft extending from the 35 to prevent the closing plate 34 from being washed away by the water flow, and in order to prevent the closing plate 34 from rotating when moving up and down, the rope 25 used to connect the closing plate 34 has two strands.

[0039] The lifting assembly 101 includes a motor 42 disposed on the pump station 11. A winding barrel 43 is fixed on a rotating shaft extending from the motor 42. The rope 25 is wound around the winding barrel 43. The motor 42 can control the rotation of the winding barrel 43, thereby controlling the lifting and lowering of the rope 25.

[0040] A top cover 51 is provided on the upper side of the pump station 11 , and climbing frames 52 equidistantly distributed up and down are provided in the pump chamber 12 .

[0041] To summarize, the clamp 102 can clamp or place the filter assembly after being lowered, the filter assembly can be stacked in the bent pipe 14, and the filter assembly is easy to disassemble, lift and clean. When performing small maintenance work, the staff only needs to clean the uppermost filter assembly without stopping the machine (the water flow needs to be small to avoid water overflowing through the inlet and outlet 24). When performing systematic maintenance work, all filter assemblies can be cleaned.

[0042] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
