Description

Technical Field

[0001] This utility model relates to the field of prefabricated pumping station technology, specifically an integrated prefabricated pumping station with a self-cleaning base design. Background Technology

[0002] Integrated prefabricated pumping stations are integrated and modular sewage or rainwater conveying and lifting equipment, mainly used to solve the problems of sewage not being able to flow by gravity and rainwater accumulation and difficulty in drainage in low-lying areas. Widely used in modern drainage systems, they are characterized by "factory prefabrication and on-site assembly." They consist of key components such as high-strength fiberglass or carbon steel prefabricated tanks, submersible pump sets, intelligent control systems, gratings, and pipeline valves. These components are assembled and debugged in the factory and then transported to the site. Only pipe network connection and foundation fixing are required, and they can be put into operation in as little as a few weeks, a construction period far shorter than the months of traditional concrete pumping stations. Compared to traditional pumping stations, they also have advantages such as small footprint (vertical cylindrical structure saves space, suitable for urban core areas), high level of intelligence (automatic monitoring of liquid level, adjustment of pump start and stop, and support for remote operation and maintenance), and good sealing (effectively isolates odors and reduces environmental impact). Currently, they are widely used in municipal drainage networks, residential areas, industrial parks, road green belts, and large public facilities such as high-speed rail stations and airports to meet drainage needs, making them key equipment for solving urban flooding and sewage collection.

[0003] Chinese Utility Model Patent Publication No. CN218028122U discloses an integrated prefabricated pump station. The specification of this integrated prefabricated pump station states that it includes an integrated prefabricated pump station body and a heat dissipation equipment body. An installation frame for assembling and disassembling the heat dissipation equipment body is fixedly installed on the outer wall of the integrated prefabricated pump station body. The top of the installation frame has a positioning slot for the heat dissipation equipment body to be inserted and positioned. A strip-shaped baffle for limiting the heat dissipation equipment body is rotatably installed on the top of the positioning slot through an installation groove. This utility model uses the installation frame to support the heat dissipation equipment body and allows for quick installation and positioning through an insertion and snap-fit ​​method. Finally, the strip-shaped baffle rotatably installed in the installation groove on the installation frame limits and fixes the heat dissipation equipment body. This not only achieves stable installation of the heat dissipation equipment body but also simplifies disassembly and improves ease of use. However, this integrated prefabricated pump station lacks a self-cleaning structure for the base. With long-term use, sludge will accumulate inside the base, potentially clogging the main pump, thus reducing its practicality. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated prefabricated pump station with a self-cleaning base design to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated prefabricated pumping station with a self-cleaning base design, comprising a prefabricated pumping station cylinder, and a prefabricated pumping station top cover and a prefabricated pumping station base distributed at the upper and lower ends of the prefabricated pumping station cylinder. A maintenance platform is provided in the middle of the interior of the prefabricated pumping station cylinder. First connecting seats are provided on both sides of the bottom end of the interior of the prefabricated pumping station cylinder. A support column is fixedly installed at the top of the end of the first connecting seat away from the inner diameter surface of the prefabricated pumping station cylinder. A main pump is fixedly installed on the upper part of the support column. A first connecting pipe is fixedly installed at the outlet end of the main pump. A valve is installed at the end of the first connecting pipe away from the main pump. A second connecting pipe is installed at the end of the valve away from the first connecting pipe. An outlet is installed at the end of the second connecting pipe away from the valve. A filter unit is fixedly installed at the lower part of the maintenance platform. An inlet is provided on the outside of the filter unit. A self-cleaning component is installed at the bottom of the prefabricated pump station cylinder above the prefabricated pump station base. A cleaning pumping pipe is installed between the self-cleaning component and the maintenance platform. The outlet of the cleaning pumping pipe is fixedly connected to the inlet of the auxiliary pump. A discharge pipe is fixedly installed at the outlet of the auxiliary pump.

[0006] Preferably, the self-cleaning component includes a side support block, a side connecting rod, and a self-cleaning seat. The side support block is fixedly connected to the prefabricated pump station cylinder. A side connecting rod is fixedly installed at the end of the side support block away from the prefabricated pump station cylinder. The end of the side connecting rod away from the side support block is fixedly connected to the self-cleaning seat. A top cover is fixedly installed at the top of the self-cleaning seat by bolts. A drive motor is fixedly installed inside the self-cleaning seat below the top cover. A transmission shaft is fixedly installed on the output shaft of the drive motor. A turntable is fixedly installed at the end of the transmission shaft away from the drive motor. Scrapers are fixedly installed in a ring on the outer diameter surface of the turntable. A guide ring is also fixedly installed on the outer side of the lower part of the self-cleaning seat. A guide groove adapted to the guide ring is opened on the side of the scraper facing the self-cleaning seat. A scraper blade is fixedly installed at the lower part of the scraper.

[0007] Through the above technical solution, the side support block and the side connecting rod provide a stable and fixed foundation for the self-cleaning seat, ensuring that it does not shift inside the pump station cylinder. After the drive motor starts, it drives the turntable to rotate through the transmission shaft, which in turn causes the ring-shaped scrapers to rotate synchronously. The scraper blades at the bottom of the scraper directly contact the inner surface of the prefabricated pump station base to scrape away the deposited silt, debris, etc. At the same time, the guide ring is embedded in the guide groove and slides, limiting the movement trajectory of the scraper and preventing it from shaking or shifting when rotating. Ultimately, this ensures that the base is always kept clean and reduces the risk of blockage of the main pump.

[0008] Preferably, the side support block and the side connecting rod are provided in two identical sets, the number of the side connecting rods is twice that of the side support block, and the side support block has an arc-shaped structure.

[0009] With the above technical solution, the two sets of side support blocks are symmetrically distributed, and with twice the number of side connecting rods, the weight of the self-cleaning seat can be evenly distributed, avoiding component deformation due to uneven force during long-term use.

[0010] Preferably, the self-cleaning seat is suspended above the prefabricated pump station base, and the lower part of the prefabricated pump station base has an open structure.

[0011] With the above technical solution, the self-cleaning seat suspended above the prefabricated pump station base will not affect the normal operation of the scraper.

[0012] Preferably, the axes of the drive shaft, the turntable, and the self-cleaning seat are located on the same vertical line, and multiple identical scrapers are provided, with the multiple scrapers arranged in a ring around the axis of the self-cleaning seat.

[0013] With the above technical solution, multiple scrapers are distributed in a ring around the axis, which can completely cover the entire plane of the prefabricated pump station base. Whether it is the center or the edge area of ​​the base, it can be contacted and cleaned by the scraper blades, which greatly improves the comprehensiveness of a single cleaning, reduces the number of cleaning times, and reduces energy consumption.

[0014] Preferably, the guide ring is embedded in the guide groove, the guide groove is adapted to the guide ring, the guide ring and the guide ring are rotatably connected, and the scraper is designed with an inclination.

[0015] Through the above technical solution, the guide ring is embedded in the guide groove and forms a rotational fit, which can limit the scraper to rotate only in the horizontal direction, prevent it from moving up and down during movement, ensure that the scraper blade is always in close contact with the base surface, and there is no cleaning gap. The inclined design of the scraper blade can scrape off the sludge when rotating, instead of accumulating in place, which makes it easier for the cleaning suction pipe to quickly remove the sludge, reduce the accumulation of sludge in the center of the base, and improve cleaning efficiency.

[0016] Preferably, the top of the prefabricated pump station cover is provided with an inspection port, an electrical control cabinet and an exhaust port. A ladder is provided inside the inspection port located inside the prefabricated pump station cylinder. The end of the cleaning pumping pipe away from the auxiliary pumping pump extends into the base of the prefabricated pump station.

[0017] The above technical solution provides an access point for staff to enter the pump station cylinder to inspect components such as the main pump and filter unit. The electrical control cabinet can centrally control the start-up, shutdown, and operating parameters of the main pump, auxiliary pump, and drive motor, facilitating real-time monitoring of equipment status and timely troubleshooting.

[0018] Compared with existing technologies, this utility model provides an integrated prefabricated pump station with a self-cleaning base design, which has the following advantages: This integrated prefabricated pump station with a self-cleaning base design uses a drive motor to rotate annularly distributed scrapers. With the limiting effect of guide rings and guide grooves, it can ensure that the scrapers are in close contact with the base surface, cleaning sludge without dead corners. The tilted scrapers can scrape off the sludge, which is then quickly pumped out by the cleaning suction pipe, preventing sludge accumulation and blockage of the main suction pump. This automated cleaning mode eliminates the need for manual entry into the cylinder for sludge removal, significantly reducing the frequency and labor intensity of manual maintenance. It also reduces the probability of equipment downtime due to blockage, ensuring continuous and stable drainage of the pump station. In addition, the filter unit at the inlet can intercept large particles of sludge in advance, reducing the source of sludge in the base from the source, further reducing the burden on the self-cleaning components, and extending the service life of core components, making it highly practical.

[0022] Example 1: like Figure 1-11 As shown, this utility model provides an integrated prefabricated pumping station with a self-cleaning base design, including a prefabricated pumping station cylinder 1, and a prefabricated pumping station top cover 3 and a prefabricated pumping station base 2 distributed at the upper and lower ends of the prefabricated pumping station cylinder 1. A maintenance platform 10 is provided in the middle of the interior of the prefabricated pumping station cylinder 1. First connecting seats 11 are provided on both sides of the bottom end of the interior of the prefabricated pumping station cylinder 1. A support column 12 is fixedly installed at the top of the end of the first connecting seat 11 away from the inner diameter surface of the prefabricated pumping station cylinder 1. A main pumping pump 13 is fixedly installed on the upper part of the support column 12. A first connecting pipe 14 is fixedly installed at the outlet end of the main pumping pump 13. The first connecting pipe 14 is away from the main pumping pump. A valve 15 is provided at one end of the 13. A second connecting pipe 16 is provided at the end of the valve 15 away from the first connecting pipe 14. An outlet 5 is installed at the end of the second connecting pipe 16 away from the valve 15. A filter unit 21 is fixedly installed at the lower part of the maintenance platform 10. An inlet 4 is provided on the outside of the filter unit 21. A self-cleaning component 20 is provided at the bottom of the prefabricated pump station cylinder 1 above the prefabricated pump station base 2. A cleaning suction pipe 17 is provided between the self-cleaning component 20 and the maintenance platform 10. The outlet of the cleaning suction pipe 17 is fixedly connected to the inlet of the auxiliary suction pump 18. A discharge pipe 19 is fixedly installed at the outlet of the auxiliary suction pump 18.

[0023] Example 2: like Figure 2-11As shown, as an improvement to the previous embodiment, the interior of the integrated prefabricated pump station base 2 is cleaned more effectively.

[0024] Specifically, the self-cleaning component 20 includes a side support block 2001, a side connecting rod 2002, and a self-cleaning seat 2003. The side support block 2001 is fixedly connected to the prefabricated pump station cylinder 1. The side connecting rod 2002 is fixedly installed at the end of the side support block 2001 away from the prefabricated pump station cylinder 1. The end of the side connecting rod 2002 away from the side support block 2001 is fixedly connected to the self-cleaning seat 2003. A top cover 2004 is fixedly installed on the top of the self-cleaning seat 2003 by bolts. The interior of the self-cleaning seat 2003 is fixed below the top cover 2004. A drive motor 2005 is installed, and a transmission shaft 2006 is fixedly installed on the output shaft of the drive motor 2005. A turntable 2007 is fixedly installed on the end of the transmission shaft 2006 away from the drive motor 2005. A scraper 2008 is fixedly installed on the outer diameter surface of the turntable 2007 in a ring shape. A guide ring 2009 is also fixedly installed on the outer side of the lower part of the self-cleaning seat 2003. A guide groove 2010 adapted to the guide ring 2009 is opened on the side of the scraper 2008 facing the self-cleaning seat 2003. A scraper blade 2011 is fixedly installed on the lower part of the scraper 2008. The advantages are that the side support block 2001 and the side connecting rod 2002 provide a stable and fixed foundation for the self-cleaning seat 2003, ensuring that it does not shift inside the pump station cylinder. After the drive motor 2005 starts, it drives the turntable 2007 to rotate through the transmission shaft 2006, which in turn causes the annularly distributed scrapers 2008 to rotate synchronously. The scraper blades 2011 at the bottom of the scraper 2008 directly contact the inner surface of the prefabricated pump station base 2 to scrape away the deposited silt, debris and other impurities. At the same time, the guide ring 2009 slides in the guide groove 2010, which restricts the movement trajectory of the scraper 2008 and prevents it from shaking or shifting when rotating. Ultimately, this ensures that the base is always kept clean and reduces the risk of blockage of the main pump 13.

[0025] Specifically, both the side support blocks 2001 and the side connecting rods 2002 are provided in two identical sets, with the number of side connecting rods 2002 being twice that of the side support blocks 2001. The side support blocks 2001 have an arc-shaped structure. The advantage is that the two sets of side support blocks 2001 are symmetrically distributed, and with twice the number of side connecting rods 2002, the weight of the self-cleaning seat 2003 can be evenly distributed, avoiding component deformation due to uneven force during long-term use.

[0026] Specifically, the self-cleaning seat 2003 is suspended above the prefabricated pump station base 2, and the lower part of the prefabricated pump station base 2 has an open structure. The advantage is that the self-cleaning seat 2003, which is suspended above the prefabricated pump station base 2, will not affect the normal operation of the scraper 2008.

[0027] Specifically, the axes of the drive shaft 2006, turntable 2007, and self-cleaning seat 2003 are located on the same vertical line. Multiple identical scrapers 2008 are provided, arranged in a ring around the axis of the self-cleaning seat 2003. The advantage is that the ring arrangement of multiple scrapers 2008 around the axis completely covers the entire plane of the prefabricated pump station base 2. Whether in the center or edge areas of the base, the scraper blades 2011 on the scrapers 2008 can contact and clean the area, significantly improving the comprehensiveness of a single cleaning, reducing the number of cleaning cycles, and lowering energy consumption.

[0028] Specifically, the guide ring 2009 is embedded inside the guide groove 2010, and the guide groove 2010 is adapted to the guide ring 2009. The guide rings 2009 and 2009 are rotatably connected, and the scraper 2011 adopts an inclined design. The advantage is that the guide ring 2009 is embedded in the guide groove 2010 and forms a rotatable fit, which can limit the scraper 2008 to rotate only in the horizontal direction, preventing it from moving up and down during movement, ensuring that the scraper 2011 is always in close contact with the base surface without any cleaning gaps. The inclined design of the scraper 2011 can scrape off the sludge when rotating, instead of accumulating in place, which makes it easier for the cleaning suction pipe 17 to quickly remove the sludge, reducing the accumulation of sludge in the center of the base and improving cleaning efficiency.

[0029] Specifically, the top of the prefabricated pump station cover 3 is equipped with an inspection port 6, an electrical control cabinet 8, and an exhaust vent 9. A ladder 7 is located inside the prefabricated pump station cylinder 1, inside the inspection port 6. The end of the cleaning suction pipe 17, away from the auxiliary suction pump 18, extends into the prefabricated pump station base 2. The advantages are that the inspection port 6 provides a passage for personnel to enter the pump station cylinder to inspect components such as the main suction pump 13 and the filter unit 21; the electrical control cabinet 8 can centrally control the start / stop and operating parameters of the main suction pump 13, the auxiliary suction pump 18, and the drive motor 2005, facilitating real-time monitoring of equipment status and timely troubleshooting.

[0030] Working principle: The integrated prefabricated pump station is started after the operating parameters are preset in the electrical control cabinet 8. The liquid to be treated first enters the prefabricated pump station cylinder 1 through the inlet 4, and flows through the filter unit 21 under the maintenance platform 10. The filter unit 21 intercepts large particles of sludge in the liquid to avoid affecting the operation of the subsequent pump. The filtered liquid naturally settles to the bottom of the cylinder and collects in the area above the prefabricated pump station base 2. Then the main pump 13 is started to extract the clear liquid at the bottom. The liquid passes through the first connecting pipe 14, valve 15, and second connecting pipe 16 in sequence, and is finally discharged from the outlet 5 to complete the liquid transportation operation. When the equipment has been running for a certain period of time or the sensor detects sludge deposits on the base, the self-cleaning component 20 starts synchronously. After the drive motor 2005 is powered on, it drives the turntable 2007 to rotate through the transmission shaft 2006. This causes the scrapers 2008, which are distributed in a ring on the outer side of the turntable 2007, to make horizontal circular motion around the axis of the self-cleaning seat 2003. During this process, the guide ring 2009 at the bottom of the self-cleaning seat 2003 slides into the guide groove 2010 of the scraper 2008, restricting the scraper 2008 to rotate only in the horizontal direction. This ensures that the scraper blades 2011 at the bottom of the scraper 2008 are in close contact with the inner surface of the prefabricated pump station base 2. The inclined scraper blades 2011 scrape away the sludge on the base. At the same time, the auxiliary pumping pump 18 starts. The sludge and a small amount of liquid pushed to the edge are extracted by the cleaning suction pipe 17 extending into the prefabricated pump station base 2, and discharged to the outside of the pump station through the discharge pipe 19, realizing the self-cleaning of the base. During the entire operation, the staff can enter the interior to inspect the main suction pump 13, filter unit 21 and other components through the inspection port 6 on the top cover 3 of the prefabricated pump station and the ladder 7 inside the cylinder. The exhaust port 9 on the top cover 3 of the prefabricated pump station continuously discharges the hot and humid air inside the cylinder to keep the interior dry. The electrical control cabinet 8 monitors the operating status of the main suction pump 13, the auxiliary suction pump 18 and the drive motor 2005 in real time. If the pump body overload, motor abnormality or other faults occur, it can automatically alarm and cut off the power supply of the corresponding equipment to ensure the stable and safe operation of the system.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
