Description

Technical Field

[0001] This utility model relates to an anti-buoyancy integrated prefabricated pumping station, belonging to the field of drainage equipment. Background Technology

[0002] The prefabricated pumping station shell is made of materials such as fiberglass and is installed underground through pre-embedding. It uses built-in water pumps to transport municipal sewage. Because the prefabricated pumping station is buried underground, it is easily affected by rising groundwater levels, which can cause the pumping station to buoy and the underlying soil to rise. The buoyancy can not only compress the pumping station shell, putting great pressure on it and making it prone to damage, but also cause the pipes to bend, leading to the risk of pipe leaks. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the technical problems in the prior art and provide an anti-buoyancy integrated prefabricated pump station.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] Anti-buoyancy integrated prefabricated pump station, including:

[0006] The pump station shell is sealed at the bottom by a base plate. Inside the pump station shell is a working area, and inside the working area is a water storage area.

[0007] The water inlet pipe is fixed to the middle of the side wall of the pump station shell, and the end of the water inlet pipe is connected to the water storage area.

[0008] The drain pipe is fixed to the top of the side wall of the pump station casing, and the end of the drain pipe is connected to the drain cavity.

[0009] The suction pipe has its end located at the bottom of the water storage area, and it is connected to the drain pipe via a suction pump.

[0010] It also includes: an anti-buoyancy pipe, the bottom of which penetrates the bottom plate of the pump station shell, and the anti-buoyancy pipe is connected to the drainage pipe through an anti-buoyancy water pump.

[0011] As a further improvement of this utility model, an anti-floating valve is provided between the anti-floating water pump and the drain pipe;

[0012] An anti-buoyancy valve is installed between the anti-buoyancy pump and the drainage pipe to control the flow of water from the anti-buoyancy pipe. This allows for adjustments to the operation of the anti-buoyancy system based on actual conditions, ensuring the stability and reliability of the anti-buoyancy function. It also helps prevent water from flowing back into the anti-buoyancy pipe to a certain extent.

[0013] As a further improvement of this utility model, an outer sleeve is provided in the middle of the pump station shell, the bottom plate includes an annular sealing spring plate, and the bottom outer wall of the outer sleeve is sealed and fixedly connected to the annular inner ring of the sealing spring plate; a floating connecting ring is provided at the top of the water storage area, and the top of the outer sleeve is floatingly connected to the inner wall of the water storage area through the floating connecting ring; the anti-buoyancy pipe extends into the outer sleeve.

[0014] The anti-buoyancy pipe extends into the outer casing, with its bottom sealed and fixedly connected to the sealing spring plate. The top of the outer casing is floatingly connected to the inner wall of the water storage area via a floating connecting ring. This design allows the outer casing to float within a certain range as the groundwater level changes. When the groundwater level rises, the outer casing rises accordingly, allowing the anti-buoyancy pipe to extract groundwater more promptly and effectively, further enhancing the anti-buoyancy effect.

[0015] As a further improvement of this utility model, the sealing spring plate includes a first outer support ring and a first inner support ring, and a stainless steel annular sealing plate is provided between the first inner support ring and the first outer support ring.

[0016] The sealing spring plate consists of a first outer support ring, a first inner support ring, and a stainless steel annular sealing plate. This structure provides good sealing performance for the connection between the bottom of the outer sleeve and the base plate, preventing groundwater from seeping into the pump station along with mud, sand, and slag, thus ensuring the normal operation of the equipment inside the pump station. At the same time, the connection of the sealing plate through the first inner support ring and the first outer support ring reduces stress concentration caused by direct welding.

[0017] As a further improvement of this utility model, the floating connecting ring includes a second outer support ring and a second inner support ring, and a stainless steel annular floating plate is provided between the second inner support ring and the second outer support ring. Several exhaust openings are arranged in an annular array on the floating plate.

[0018] The second outer support ring, the second inner support ring, and the stainless steel annular floating plate structure of the floating connecting ring make the connection between the top of the outer sleeve and the inner wall of the water storage area both firm and flexible. It can maintain the reliability of the connection when the outer sleeve floats, without damaging the inner wall of the water storage area.

[0019] As a further improvement of this utility model, a connecting frame is provided inside the outer tube. The connecting frame of the outer tube includes a main connecting sleeve fixed to the inner wall of the outer tube. The inner ring of the main connecting sleeve is connected to an inner connecting sleeve by a connecting rib. The inner connecting sleeve is fixed to the outer wall of the anti-buoyancy tube.

[0020] The connecting frame can be used to hoist the anti-buoyancy tube, preventing it from hitting the inner wall of the outer sleeve and affecting its normal floating.

[0021] As a further improvement of this utility model, a conical water collection hood is connected to the bottom of the anti-buoyancy pipe, and the water collection hood is arranged outside the pump station shell through the anti-buoyancy pipe.

[0022] The bottom of the anti-buoyancy pipe is connected to a conical water collection hood and arranged outside the pump station shell. The water collection hood can expand the groundwater collection range, improve the water absorption efficiency of the anti-buoyancy pipe, lower the groundwater level around the pump station more quickly, and enhance the anti-buoyancy effect.

[0023] As a further improvement of this utility model, a bottom support ring is provided at the bottom of the pump station shell, and several water inlet openings are arranged in a circular array on the bottom support ring, with the water collection cover located inside the bottom support ring;

[0024] The bottom support ring can further increase water absorption efficiency.

[0025] As a further improvement of this utility model, an annular connecting platform is provided at the bottom of the pump station shell, and a mesh-like equipment support ring is provided on the connecting platform, with the water pump fixed on the equipment support ring.

[0026] A mesh support ring is installed on the bottom connecting platform of the pump station casing to fix the water pump to the support ring. This design provides a stable installation position for the water pump, so that the water pump can be firmly fixed in the pump station and avoid displacement or damage due to vibration or other reasons during operation.

[0027] The beneficial effects of this utility model are:

[0028] The anti-buoyancy pipe penetrates the bottom plate of the pump station shell and is connected to the drainage pipe through the anti-buoyancy pump. It can directly extract the groundwater at the bottom of the pump station, effectively lower the groundwater level, thereby reducing the buoyancy effect of the groundwater on the pump station and enhancing the pump station's anti-buoyancy capability.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0037] Example 1

[0038] like Figure 1 As shown, the anti-buoyancy integrated prefabricated pump station includes:

[0039] The pump station shell 1 has a fixed base plate 2 at its bottom, which seals the bottom of the pump station shell 1. A top cover 11 is installed on the top of the pump station shell 1 to facilitate access for maintenance workers. A working area is set inside the pump station shell 1, and a water storage area is set inside the working area. An equipment platform 10 is set in the middle of the pump station shell 1, which separates the upper part of the working area into a working area for simple maintenance and cleaning of the inside of the pump station shell 1. An annular connecting seat 3 is set on the outer side of the bottom of the pump station shell 1. The connecting seat 3 is mainly used for hoisting and anchoring the pump station shell 1. Hoisting holes and anchoring holes are arranged on the connecting seat 3.

[0040] The water inlet pipe 7 is fixed in the middle of the side wall of the pump station shell 1. The end of the water inlet pipe 7 is connected to the water storage area, and the other end of the water inlet pipe 7 is connected to the municipal sewage and rainwater pipelines. A dirt-proof net 9 can also be hoisted and fixed inside the pump station shell 1 at the position corresponding to the water inlet pipe 7.

[0041] Drainage pipe 8 is fixed to the top of the side wall of the pump station shell 1. The end of drainage pipe 8 is connected to the drainage chamber. Drainage pipe 8 mainly transports sewage and rainwater from the pump station to the discharge pipeline.

[0042] There are generally at least two sets of suction pipes 4. The end of the suction pipe 4 is located at the bottom of the water storage area. The suction pipe 4 is connected to the drain pipe 8 through the suction pump 5.

[0043] It also includes: an anti-buoyancy pipe 12, the bottom of which penetrates the bottom plate 2 of the pump station shell 1, and the anti-buoyancy pipe 12 is connected to the drainage pipe 8 through the anti-buoyancy water pump 13.

[0044] The anti-buoyancy pipe 12 and the suction pipe 4 are connected to the drain pipe 8 through the anti-buoyancy valve 14 and the suction valve 6, respectively.

[0045] By default, the anti-buoyancy valve 14 is closed, and the suction pump 5 of the suction pipe 4 discharges the accumulated water in the pump station's storage area according to the liquid level. However, when the rainfall is large or the average water level rises and the groundwater level increases accordingly, the groundwater and rainwater, along with the seepage water, will squeeze the pump station's outer shell 1. At this time, the suction valve 6 can be selectively opened or closed according to the liquid level in the storage area, while the anti-buoyancy valve 14 is opened. The seepage water on the outside of the pump station's outer shell 1 is then sucked into the drain pipe 8 by the anti-buoyancy pump, thereby reducing the impact of the buoyancy generated by the groundwater on the stability of the pump station's outer shell 1.

[0046] Example 2

[0047] like Figure 2 As shown, this utility model is an integrated anti-buoyancy prefabricated pump station, comprising:

[0048] like Figure 2 The pump station shell 1 has a working area inside, which contains a water storage area. An equipment platform 10 is located in the middle of the pump station shell 1, which separates the upper part of the working area into a working zone for simple maintenance and cleaning of the pump station shell 1. A ring-shaped connecting seat 3 is located on the outer bottom of the pump station shell 1. The connecting seat 3 is mainly used for hoisting and anchoring the pump station shell 1. Hoisting holes and anchoring holes are arranged on the connecting seat 3.

[0049] like Figure 2 The bottom of the pump station casing 1 is provided with an annular connecting platform 21, and a mesh equipment support ring 22 is provided on the connecting platform 21. The water pump 5 is fixed on the equipment support ring 22.

[0050] like Figure 2 An outer sleeve 15 is provided in the middle of the pump station shell 1. An annular sealing spring plate 17 is provided between the inner wall of the bottom of the pump station shell 1 corresponding to the connecting platform 21 and the outer wall of the outer sleeve 15. The bottom outer wall of the outer sleeve 15 is sealed and fixedly connected to the annular inner ring of the sealing spring plate 17. A floating connecting ring 18 is provided at the top of the water storage area. The top of the outer sleeve 15 is floatingly connected to the inner wall of the water storage area through the floating connecting ring 18. The anti-buoyancy pipe 12 and the anti-buoyancy pump of the anti-buoyancy pipe 12 extend into the outer sleeve 15.

[0051] like Figure 3 and Figure 4 The sealing spring plate 17 includes a first outer support ring 17-3 and a first inner support ring 17-2. A stainless steel annular sealing plate 17-1 is disposed between the first inner support ring 17-2 and the first outer support ring 17-3. The sealing plate 17-1 is embedded in the inlay groove of the first inner support ring 17-2 and the first outer support ring 17-3. The floating connecting ring 18 includes a second outer support ring 18-3 and a second inner support ring 18-4. A stainless steel annular floating plate 18-1 is disposed between the second inner support ring 18-4 and the second outer support ring 18-3. The floating plate 18-1 is also embedded in the second outer support ring 18-3 and the second inner support ring 18-4. A plurality of exhaust openings 18-2 are arranged in a circular array on the floating plate 18-1.

[0052] like Figure 5 In order to improve the connection stability between the outer sleeve 15 and the anti-buoyancy tube 12 and reduce the impact caused by the radial floating of the outer sleeve 15 and the anti-buoyancy tube 12, a connecting frame 23 is provided inside the outer sleeve 15. The connecting frame 23 of the outer sleeve 15 includes a main connecting sleeve 23-1 fixed to the inner wall of the outer sleeve 15. The inner ring of the main connecting sleeve 23-1 is connected to an inner connecting sleeve 23-2 through a connecting rib 23-3. The inner connecting sleeve 23-2 is fixed to the outer wall of the anti-buoyancy tube 12.

[0053] The bottom of the pump station shell 1 is provided with a bottom support ring 19, and a number of water inlet openings 20 are arranged in a ring array on the bottom support ring 19. A conical water collection cover 16 connected to the bottom of the anti-buoyancy pipe 12 is provided inside the bottom support ring 19. The water collection cover 16 is arranged outside the pump station shell 1 through the anti-buoyancy pipe 12.

[0054] By default, the anti-buoyancy valve 14 is closed, and the suction pump 5 of the suction pipe 4 discharges the accumulated water in the pump station's water storage area according to the liquid level. However, when the rainfall is large or the average water level rises and the groundwater level increases accordingly, the suction valve 6 can be selectively opened or closed according to the liquid level in the water storage area. At the same time, the anti-buoyancy valve 14 is opened, and the groundwater outside the pump station shell 1 is sucked into the drainage pipe 8 by the anti-buoyancy pump, thereby reducing the impact of the buoyancy generated by the groundwater outside the bottom plate 2 of the pump station shell 1 on the stability of the pump station shell 1.

[0055] Groundwater mainly enters the water collection hood 16 through the water inlet 20 on the side of the bottom support ring 19 and the opening at the bottom of the bottom support ring 19. It then accumulates in the outer casing 15. When the water level in the outer casing 15 reaches a certain level, the water in the outer casing 15 is sucked into the anti-buoyancy pipe 12 by the anti-buoyancy pump and then discharged through the drainage pipe 8.

[0056] Because the underground soil is also affected by the buoyancy of the seepage water, the seepage water squeezes the outer shell 1 of the pump station. The bottom support ring 19 provided in this application provides a certain space for the squeezing. At the same time, the floating outer sleeve 15 is provided to reduce the squeezing effect of buoyancy on the rigidly fixed anti-buoyancy pipe 12. It can also prevent the anti-buoyancy pipe 12 from directly contacting the soil and reduce the possibility of blockage of the anti-buoyancy pipe 12.

[0057] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
