Description

Technical Field

[0001] This utility model relates to the field of rainwater pumping stations, and in particular to a forced-drainage rainwater pumping station with a weir gate. Background Technology

[0002] Stormwater pumping stations are pumping stations established to drain urban stormwater. They play an important role in draining urban stormwater and preventing urban flooding. They use pumping equipment to discharge urban stormwater into rivers or other water bodies and are an indispensable part of the urban drainage system. With the continuous expansion of urban areas, during heavy rain, the excessive rainfall makes it difficult for stormwater pumping stations to effectively and promptly drain water, easily leading to urban flooding. Furthermore, during the water intake process, numerous foreign objects adhere to the surface of the inlet pipes, gradually clogging them and affecting drainage efficiency. Therefore, to solve these problems, designing a forced-drainage stormwater pumping station with a weir gate is a necessary consideration. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a forced-drainage rainwater pumping station with a weir gate. To address usage issues, it incorporates a weir gate assembly and a pumping assembly. By controlling two telescopic rods to lower the gate panel, and in conjunction with multiple pump bodies, rainwater in the storage tank can be efficiently discharged, preventing urban flooding. A cleaning assembly is also included, using multiple fan blades to drive two scrapers to remove foreign objects from the filter screen, ensuring drainage efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A forced-flow stormwater pumping station with a weir gate includes a main body of the stormwater pumping station, a water storage tank at the upper end of the main body, an inlet pipe at the front of the main body, a filter screen at the front of the inlet pipe, and a water conveyance channel on the rear inner wall of the water storage tank; a weir gate assembly, including a weir frame fixedly connected to the rear of the main body, a movable gate panel on the inner side of the weir frame, fixed blocks on both sides of the gate panel, two telescopic rods symmetrically installed on the inner top of the weir frame, and the telescopic ends of the two telescopic rods fixedly connected to the upper ends of the corresponding fixed blocks; a cleaning assembly for cleaning the filter screen; and a pumping assembly for pumping water from the water storage tank.

[0005] Preferably, two guide rods are symmetrically fixedly connected to the inner top of the weir frame, and the lower ends of the two guide rods pass through the door panel and are slidably connected.

[0006] Preferably, both telescopic rods are hydraulic telescopic rods.

[0007] Preferably, the front and rear sides of the door panel are slidably connected to the inner wall of the weir frame, and the two fixing blocks are slidably connected to the inner wall of the weir frame.

[0008] Preferably, the cleaning assembly includes a rotating shaft horizontally disposed through the middle of the filter screen, the rotating shaft being rotatably connected to the filter screen, and two rotating rods being fixedly connected to the front end of the rotating shaft, with scrapers installed on the rear side of each of the two rotating rods.

[0009] Preferably, both scrapers are inclined.

[0010] Preferably, an annular connecting block is fixedly connected to the rear side of the rotating shaft, and multiple fan blades are fixedly connected to the outer side of the annular connecting block.

[0011] Preferably, both scrapers are fitted with a filter screen.

[0012] Preferably, the pumping assembly includes multiple pump bodies installed on the upper part of the rainwater pumping station body, each pump body having an inlet end connected to a pumping pipe, and the other end of each pumping pipe extending to the inner bottom of the water storage tank.

[0013] Preferably, each of the pump bodies has a drain pipe connected to its outlet end, and the other end of each drain pipe extends to the rear side of the rainwater pumping station body.

[0014] Compared with the prior art, the advantages of this utility model are as follows: 1. A weir gate assembly and a pumping assembly are installed. By controlling two telescopic rods, the gate panel is moved down to the designated discharge height. With the help of multiple water pumps, the rainwater accumulated in the reservoir can be discharged efficiently. Compared with the traditional method of drainage by pumping equipment alone, this method effectively improves the actual drainage efficiency and avoids the situation of untimely drainage during heavy rain.

[0015] A cleaning component is installed. During the drainage process, multiple fan blades rotate with the water flow, which drives two scrapers to rotate synchronously. This scrapes off foreign objects adhering to the filter screen of the inlet pipe, preventing foreign objects from clogging the filter screen and affecting the actual drainage efficiency.

Detailed Implementation

[0018] Reference Figures 1-4 A forced-drainage rainwater pumping station with a weir gate includes a rainwater pumping station body 1, a water storage tank 2 at the upper end of the rainwater pumping station body 1 for collecting rainwater, an inlet pipe 3 at the front of the rainwater pumping station body 1, a filter screen 4 at the front of the inlet pipe 3 to prevent large foreign objects from entering the water storage tank 2, and a water conveying channel 5 on the rear inner wall of the water storage tank 2. The system also includes a weir gate assembly, which includes a weir frame 6 fixedly connected to the rear side of the main body 1 of the rainwater pumping station. A door panel 7 that can move up and down is provided on the inner side of the weir frame 6. The front and rear sides of the door panel 7 are slidably connected to the inner wall of the weir frame 6. Fixing blocks 8 are fixedly connected to the left and right sides of the door panel 7. Both fixing blocks 8 are slidably connected to the inner wall of the weir frame 6. Two telescopic rods 9 are symmetrically installed on the inner top of the weir frame 6. Both telescopic rods 9 are hydraulic telescopic rods. The telescopic ends of both telescopic rods 9 are fixedly connected to the upper end of the corresponding fixing blocks 8. Two guide rods 10 are symmetrically fixedly connected to the inner top of the weir frame 6. The lower ends of both guide rods 10 penetrate the door panel 7 and are slidably connected. The two guide rods 10 can improve the stability of the door panel 7 when it moves up and down. The system also includes a cleaning component for cleaning the filter screen 4. The cleaning component includes a rotating shaft 11 that is horizontally disposed through the middle of the filter screen 4. The rotating shaft 11 is rotatably connected to the filter screen 4. Two rotating rods 12 are fixedly connected to the front end of the rotating shaft 11. Scrapers 13 are installed on the rear side of each of the two rotating rods 12. Both scrapers 13 are inclined and cooperate with the filter screen 4. By rotating the two scrapers 13, foreign objects adhering to the filter screen 4 can be scraped off, thereby preventing the filter screen 4 from becoming clogged. An annular connecting block 14 is fixedly connected to the rear side of the rotating shaft 11. Multiple fan blades 15 are fixedly connected to the outer side of the annular connecting block 14. The system also includes a pumping assembly, which is used to pump water from the reservoir 2. The pumping assembly includes multiple pump bodies 16 installed on the upper part of the rainwater pumping station body 1. The inlet end of each pump body 16 is connected to a pumping pipe 17, and the other end of each pumping pipe 17 extends to the bottom of the reservoir 2. The outlet end of each pump body 16 is connected to a drain pipe 18, and the other end of each drain pipe 18 extends to the rear side of the rainwater pumping station body 1, which can pump rainwater from the reservoir 2 to the outside river.

[0019] In this utility model, the inlet pipe 3 is connected to the rainwater discharge pipe of the municipal pipe network. The rear side of the rainwater pumping station body 1 is close to the river. When the amount of rainwater is not large, the rainwater enters the storage tank 2 through the inlet pipe 3. During this period, the staff can start multiple pump bodies 16 to pump the rainwater in the storage tank 2 into the river through the pumping pipe 17 and the drainage pipe 18. When the amount of rainwater continues to increase, while controlling multiple pump bodies 16 to pump rainwater, the staff can control two telescopic rods 9 to drive the corresponding fixed blocks 8 to move down, and drive the door panel 7 to move down synchronously until the specified discharge height is reached (the specific height can be adjusted according to the actual situation). In this way, when the height of the rainwater accumulated in the storage tank 2 exceeds the height of the door panel 7, the rainwater in the storage tank 2 can be gradually discharged into the river from the top of the door panel 7 through the water conveying channel 5, thereby improving the actual drainage efficiency and avoiding the situation of urban flooding caused by the rainwater pumping station not draining in time during rainstorms. It is worth mentioning that during the process of rainwater entering the water storage tank 2 through the inlet pipe 3, the flowing rainwater can drive multiple fan blades 15 to rotate, drive the rotating shaft 11 to rotate, and drive the two rotating shafts 11 and the two scrapers 13 to rotate synchronously. During this period, the two scrapers 13 can scrape off the foreign objects adhering to the filter screen 4, thereby preventing the foreign objects from clogging the filter screen 4 and affecting the drainage efficiency of the entire equipment.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
