Description

Technical Field

[0001] The present invention relates to the technical field of flood control pump stations, in particular to an integrated pump station for flood control and drainage with an anti-blocking function. Background Art

[0002] Flood control and drainage pump stations are core facilities for urban waterlogging prevention and control and river basin flood control. Their operational reliability is directly related to the safety of people's lives and property and the normal order of the city. Traditional integrated pump stations mostly use open water inlet structures. Under heavy rain or flood conditions, water often carries a large amount of debris such as aquatic plants, dead branches and leaves, plastic garbage, and mud and sand. These debris can easily accumulate and entangle at the water inlet grille, forming a physical blockage. Existing technologies mainly alleviate this problem by adding mechanical grilles and combining them with regular manual dredging. However, there are significant drawbacks. Debris intercepted by the mechanical grille must be manually cleaned after the machine is shut down. During continuous heavy rain, it cannot be cleared in time, resulting in a rapid reduction in the flow cross-section. Fine particles of mud and sand can easily penetrate the grille and enter the pump body, causing impeller wear or flow channel siltation, reducing pump efficiency. During sudden heavy rainfall, the instantaneous influx of debris may directly block the grille, causing the pump to idle or overload and shut down, losing critical drainage opportunities. Frequent dredging operations increase manpower input, and downtime maintenance affects the overall reliability of the system. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] Example: Figure 1-Figure 7 As shown, the present invention provides a technical solution, an integrated pump station for flood control and drainage with anti-blocking function, comprising a pump room 1, a suction pipe 2, a water outlet trough 3, a water outlet pipe 4 and a river water diversion trough 5. A control cabinet, a motor and a pump body are provided in the pump room 1. The control cabinet is connected to the motor through a circuit, and the motor is connected to the pump body. The pump body is connected to the middle part of the suction pipe 2. The suction end of the suction pipe 2 is located in the river water diversion trough 5, and the water outlet end of the suction pipe 2 is in the water outlet trough 3. The water outlet pipe 4 is connected to the end of the water outlet trough 3 away from the suction pipe 2. A dynamic filtering component is provided in the river water diversion trough 5, and the dynamic filtering component filters impurities in the river water. The operator supplies power to the motor through the control cabinet, and the motor drives the water pump to work. The water pump draws water from the river water diversion trough 5 through the suction pipe 2, discharges it into the water outlet trough 3, and then flows out from the water outlet pipe 4.

[0017] A negative pressure compartment 28 is provided at the bottom of the river water diversion trough 5, the pumping end of the pumping pipe 2 is located inside the negative pressure compartment 28, and the pumping end of the pumping pipe 2 is provided with a filter.

The top of each water drive wheel 29 is connected to a transmission shaft 30, and each transmission shaft 30 is installed with a primary driving pulley 24. Two second support columns 7 are symmetrically provided on both sides of the river water diversion trough 5, and a first double wheel and a second double wheel are rotatably provided on each second support column 7. The rotating shafts of the first double wheel and the second double wheel are perpendicular to each other. The first double wheel is composed of a first bevel gear 22 and a primary driven pulley coaxially connected, and the first double wheel is composed of a second bevel gear 23 and a secondary driving pulley 19 coaxially connected. The first bevel gear 22 is meshed with the second bevel gear 23, and the two primary driving pulleys 24 are respectively connected to the two primary driven pulleys through two first V-belts 26.

[0018] The suction pipe 2 draws water from the negative pressure compartment 28, the pressure in the negative pressure compartment 28 decreases, and water flows into the negative pressure compartment 28 from the river water diversion trough 5. The water flow drives the two water drive wheels 29 to rotate. Since the two driving sprockets 10 at the end of the transmission chain are connected by a synchronous shaft 11, the rotation speed of the two driving sprockets 10 is constrained to be consistent. Therefore, the rotation speed of the two water drive wheels 29 is also constrained. The two water drive wheels 29 keep rotating synchronously, and the rotational power is output to the two primary driving pulleys 24 through the two transmission shafts 30. The two primary driving pulleys 24 rotate at the same time. The two primary driving pulleys 24 drive the two primary driven pulleys to rotate through the two first V-belts 26. The two primary driven pulleys drive the two first bevel gears 22 to rotate. The two first bevel gears 22 respectively drive the two second bevel gears 23 to rotate. The two second bevel gears 23 make the two secondary driving pulleys 19 rotate synchronously.

[0019] Two first support columns 6 are symmetrically arranged on both sides of the river water diversion trough 5, and a third double wheel is rotatably installed on each first support column 6. The third double wheel is formed by a secondary driven pulley 20 and a driving sprocket 10 coaxially connected.

The dynamic filtering component includes a pair of front reversing sprockets 8, a pair of rear reversing sprockets 9, a synchronous shaft 11, a first chain 13 and a second chain 14. The synchronous shaft 11 is connected between the two driving sprockets 10. The pair of front reversing sprockets 8 and the pair of rear reversing sprockets 9 are symmetrically arranged on both sides of the river water diversion trough 5. The pair of rear reversing sprockets 9 are located below the driving sprocket 10, and the pair of front reversing sprockets 8 are located away from the rear reversing sprocket 9. On one side of the pump room 1, the first chain 13 and the second chain 14 are symmetrically arranged on both sides of the river water diversion trough 5. The first chain 13 is connected to the front reversing sprocket 8, the rear reversing sprocket 9 and the drive sprocket 10 on the same side. The second chain 14 is arranged in the same way as the first chain 13. The dynamic filtration assembly includes several support bodies, and the several support bodies are arranged at equal intervals between the first chain 13 and the second chain 14. Each support body includes a supporting rod 15 and three spring boxes 17. The supporting rod 15 is connected between the first chain 13 and the second chain 14. The three spring boxes 17 are all installed on the supporting rod 15. A telescopic hook 18 is slidably installed in each spring box 17, and a spring is arranged between the telescopic hook 18 and the inside of the spring box 17.

[0020] The two secondary driving pulleys 19 drive the two secondary driven pulleys 20 to rotate through the two second V-belts 21. The two secondary driven pulleys 20 drive the first chain 13 and the second chain 14 to move through the driving sprocket 10. The water in the river channel passes through the fine filter screen 16 and enters the negative pressure compartment 28. The aquatic plants, silt and garbage in the water body are all intercepted by the fine filter screen 16. The supporting thin rod 15 moves synchronously with the first chain 13 and the second chain 14. The fine filter screen 16 also moves synchronously with the first chain 13 and the second chain 14. The supporting thin rod 15 plays a role in supporting the fine filter screen 16 to prevent the fine filter screen 16 from being broken by water flow or debris. The debris trapped outside the fine filter screen 16 contacts the telescopic hook 18, and the debris is hooked by the telescopic hook 18 and pulled upward until the aquatic plants, silt and garbage are blocked by the scraper cover 27 and are further intercepted on the scraper cover 27.

[0021] Three spring boxes 17 are arranged alternately on every two adjacent supports. The dynamic filtration assembly also includes a fine filter 16. The fine filter 16 is wrapped around the outside of all supports. All telescopic hooks 18 pass through the fine filter 16. A magnetic plate 12 is provided in the river water diversion trough 5. The magnetic plate 12 is located in the space surrounded by the fine filter 16. The magnetic plate 12 is arranged near the rear reversing sprocket 9 and the driving sprocket 10. A scraper cover 27 is provided on the river water diversion trough 5. The scraper cover 27 is in contact with the outside of the fine filter 16. The middle part of the scraper cover 27 is higher than the two sides. A sewage collecting tank (not shown in the figure) is provided below the two sides of the scraper cover 27. When the telescopic hook 18 is about to contact the scraper cover 27, the magnetic plate The 12 pairs of telescopic hooks 18 that are close to each other have the greatest attraction. The telescopic hooks 18 are sucked into the spring boxes 17, and the garbage hooked by the telescopic hooks 18 falls onto the scraper cover 27. At the same time, the telescopic hooks 18 pass through the scraper cover 27 smoothly. After the telescopic hooks 18 leave the adsorption area of the magnetic plate 12, the spring box 17 is popped out under the action of the spring to drag and process the aquatic plants, mud and garbage in the water body. The debris eventually rolls into the sewage collection pool through the scraper cover 27. The operator regularly processes the debris in the sewage collection pool. By setting up a dynamic filtering component and utilizing the power generated by pumping water, the impurities in the water body are continuously dragged and processed to prevent the fine filter screen 16 from being blocked, thereby realizing the functions of self-cleaning and anti-blocking of impurities.

[0022] The working principle of the present invention is as follows: the operator supplies power to the motor through the control cabinet, and the motor drives the water pump to work. The water pump draws water from the river water diversion trough 5 through the water pumping pipe 2, discharges it into the water outlet trough 3, and then flows out from the water outlet pipe 4. The water pumping pipe 2 draws water from the negative pressure compartment 28, and the pressure in the negative pressure compartment 28 decreases. Water flows from the river water diversion trough 5 into the negative pressure compartment 28, and the water flow drives the two water drive wheels 29 to rotate. Since the two drive sprockets 10 at the end of the transmission chain are connected by a synchronous shaft 11, the rotation speeds of the two drive sprockets 10 are constrained to be consistent, so The rotational speed of the two water drive wheels 29 is also constrained, and the two water drive wheels 29 keep rotating synchronously. The rotational power is output to the two primary driving pulleys 24 through the two transmission shafts 30. The two primary driving pulleys 24 rotate simultaneously. The two primary driving pulleys 24 drive the two primary driven pulleys to rotate through the two first V-belts 26. The two primary driven pulleys drive the two first bevel gears 22 to rotate. The two first bevel gears 22 respectively drive the two second bevel gears 23 to rotate. The two second bevel gears 23 make the two secondary driving pulleys 19 rotate synchronously.

[0023] The two secondary driving pulleys 19 drive the two secondary driven pulleys 20 to rotate through the two second V-belts 21. The two secondary driven pulleys 20 drive the first chain 13 and the second chain 14 to move through the driving sprocket 10. The water in the river channel passes through the fine filter screen 16 and enters the negative pressure compartment 28. The aquatic plants, silt and garbage in the water body are all intercepted by the fine filter screen 16. The supporting thin rod 15 moves synchronously with the first chain 13 and the second chain 14. The fine filter screen 16 also moves synchronously with the first chain 13 and the second chain 14. The supporting thin rod 15 plays a role in supporting the fine filter screen 16 to prevent the fine filter screen 16 from being broken by water flow or debris. The debris trapped outside the fine filter screen 16 contacts the telescopic hook 18, and the debris is hooked by the telescopic hook 18 and pulled upward until the aquatic plants, silt and garbage are blocked by the scraper cover 27 and are further intercepted on the scraper cover 27.

[0024] When the telescopic hook 18 is about to contact the scraper cover 27, the magnetic plate 12 has the greatest attraction to the approaching telescopic hook 18, and the telescopic hook 18 is sucked into the spring box 17. The garbage hooked by the telescopic hook 18 falls onto the scraper cover 27. At the same time, the telescopic hook 18 passes through the scraper cover 27 smoothly. After the telescopic hook 18 leaves the adsorption area of the magnetic plate 12, the spring box 17 is popped out under the action of the spring, and the aquatic plants, mud and garbage in the water body are dragged and processed. The debris eventually rolls into the sewage collection tank through the scraper cover 27. The operator regularly processes the debris in the sewage collection tank. By setting up a dynamic filtering component and utilizing the power generated by pumping water, the impurities in the water body are continuously dragged and processed to prevent the fine filter screen 16 from being blocked, thereby realizing the functions of self-cleaning and anti-blocking of impurities.
