[0028] like Figures 1-5 As shown, a low-noise sewage treatment pumping station includes:

[0029] The integrated pump station 1, the top of the integrated pump station 1 is provided with a manhole 12;

[0030] The manhole 12 is provided above with a sealing part 2, the sealing part 2 comprises an outer cover 23, the bottom of the outer cover 23 is in an open shape, and a vacuum sound insulation layer 230 is arranged in the inner part of the outer cover 23; an inner cover 20 is arranged in the bottom opening of the outer cover 23, the inner cover 20 is also in an open shape, the manhole 12 is inserted into the bottom opening of the inner cover 20, and the outer diameter of the manhole 12 is slightly smaller than the inner diameter of the inner cover 20; a sound insulation pad 22 is arranged in the gap between the inner cover 20 and the outer cover 23. The outer diameter of the manhole 12 is slightly smaller than the inner diameter of the inner cover 20, which facilitates the stable connection between the manhole 12 and the inner cover 20, and ensures the sealing and noise reduction effects.

[0031] As shown in Figure 3 The two side walls of the outer cover 23 are both fixed with a connecting block 24 at the bottom end, and the connecting block 24 is provided with a through hole; the two side walls of the inner cover 20 are both fixed with an ear plate 21 at the bottom end, the ear plate 21 is provided with a threaded hole 210, the positions of the plurality of through holes and the plurality of threaded holes 210 correspond, and a connecting bolt 240 is screwed into the threaded hole 210 after passing through the through hole, so as to pull and fix the inner cover 20 and the outer cover 23.

[0032] As shown in Figures 1-4 The sewage treatment pump station further comprises a transmission shaft 26, the left and right sides of the manhole 12 are both fixed with a support 14, the two opposite end faces of the two supports 14 are both provided with an insertion slot 140, the top of the outer cover 23 is fixed with two connecting seats 25, the two connecting seats 25 are arranged on a straight line, the two opposite end faces of the two connecting seats 25 are both provided with a sliding cavity 250, a sliding block 28 is slidably arranged in the sliding cavity 250, the two opposite end faces of the two sliding blocks 28 are both provided with a threaded cavity 280, the end of the sliding block 28 passes out of the sliding cavity 250 and is inserted and matched with the corresponding insertion slot 140; the two ends of the transmission shaft 26 are respectively provided with two sections of threads with opposite threads, the two ends of the transmission shaft 26 are respectively screwed with the two threaded cavities 280, the two connecting seats 25 are arranged with a gap, and the middle part of the transmission shaft 26 is exposed in the gap. Through the insertion and matching of the sliding block and the insertion slot, the sealing part and the manhole are conveniently installed and fixed, and the sliding block is separated from the insertion slot, so as to conveniently disassemble the sealing part; the design facilitates the disassembly and assembly of the sealing part, and meets the use requirements.

[0033] As shown in Figures 3-4As shown, the center of the transmission shaft 26 is coaxially connected with a roller 27, and the outer wall of the roller 27 is provided with a plurality of anti-skid grooves. In operation, the transmission shaft 26 can be rotated by rotating the roller 27, because the two ends of the transmission shaft 26 are threadedly connected with the two threaded cavities 280, and because the two ends of the transmission shaft 26 are provided with two sections of opposite threads, the two sliding blocks 28 are simultaneously moved inward or outward, and when moved outward, the two sliding blocks 28 can be respectively inserted into the two insertion grooves 140, so as to lock the position of the outer cover 23.

[0034] As shown in Figure 2 The manhole 12 has a rectangular cross-sectional shape.

[0035] As shown in Figures 1-2 The outer wall of the integrated pump station 1 is provided with a drain 11 and a water inlet 10 at the upper and lower sides, respectively, and the control cabinet 13 is installed at the rear side of the manhole 12. The drain 11 and the water inlet 10 facilitate the entry and exit of sewage, and the control cabinet 13 facilitates the control of the water pump in the integrated pump station 1.

[0036] As shown in Figure 3 The connecting seat 25 is fixedly connected with the top of the outer cover 23 by bolts, and the vertical cross-sectional shape of the connecting seat 25 is rectangular. The bolted connection ensures the stability and reliability of the installation of the connecting seat 25.

[0037] In some embodiments, the non-threaded part of the transmission shaft 26 is sleeved with a bearing, and the bearing is installed in the sliding cavity 250.

[0038] It should be noted that the sound insulation pad 22 in the present embodiment is a finished product made of polyurethane material, which not only has good sound absorption effect, but also is light in weight and easy to install. The use of this material can improve the sound insulation effect of the outer cover 23 and the inner cover 20. At the same time, since sound is difficult to propagate in a vacuum environment, the setting of the vacuum sound insulation layer 230 further increases the sound insulation effect at the manhole 12.

[0039] In specific use, the noise inside the integrated pump station 1 propagates to the manhole 12, and under the action of the sound insulation pad 22 and the vacuum sound insulation layer 230, the noise is difficult to propagate to the outside through the manhole 12, the outer cover 23 and the inner cover 20.

[0040] When the sealing part 2 needs to be removed, the user first rotates the roller 27, the roller 27 drives the transmission shaft 26 to rotate, and the sliding blocks 28 on both sides move synchronously inward, and the ends of the sliding blocks 28 are separated from the insertion grooves 140. At this time, the user stops rotating the roller 27, and then the user lifts the sealing part 2 upward, and the sealing part 2 is separated from the manhole 12.

[0041] The above merely is the preferred implementation manner of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
