Description

Technical Field

[0001] The utility model belongs to the technical field of rainwater pumping stations, in particular to a rectifier system for rainwater pumping stations. Background Art

[0002] Rainwater pumping stations are an important part of environmental, municipal and water conservancy projects, and play an extremely important role in urban water supply. When the water level at the outlet of the rainwater pipe is high and the rainwater cannot be discharged by gravity; or when the highest water level of the water body is higher than the ground of the drainage area, a rainwater pumping station should be set up in front of the outlet of the rainwater pipe. The rainwater pumping station can discharge the rainwater at the bottom through a submersible pump, reducing the probability of waterlogging.

[0003] After searching, Chinese patent publication number CN220538838U discloses a rectifier device for a rainwater pumping station. By arranging a junction box and an inlet box above the base, and arranging several rainwater ducts above the inlet box, it cooperates with the partition inside the inlet box to realize independent water diversion, and cooperates with the frame plate and the filter to effectively filter the gravel and other impurities carried by the rainwater. Finally, it cooperates with the junction box and the rainwater delivery pipe to realize rectified delivery, which can effectively reduce the probability of pipeline blockage during rainwater transmission and ensure the long-term stable operation of the rainwater pumping station.

[0004] The silt, gravel and other impurities filtered out in the existing device need to be cleaned manually, which has high labor costs and poses a safety hazard to workers. When the incoming rainwater is mixed with sewage, the filtered impurities will have a pungent odor, and inhaling the odor is not good for the health of workers. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figure 1-Figure 4 A rectifier system for a rainwater pumping station includes a rainwater pumping station body 1 and a silt removal mechanism. An inlet pipe 11 and an outlet pipe 12 are fixedly connected to the side wall of the rainwater pumping station body 1. The inlet pipe 11 is connected to a second drainage pipe 111. A one-way valve 112 is provided on the second drainage pipe 111. Rainwater in the municipality is drained into the inlet pipe 11 through the second drainage pipe 111. The one-way valve 112 only allows rainwater to enter the inlet pipe 11 from the outside. A filter plate 13 is fixedly connected to one end of the inlet pipe 11 close to the rainwater pumping station body 1. A reinforcing plate 131 is fixedly connected between the filter plate 13 and the inlet pipe 11 to prevent the filter plate 13 from falling off due to long-term impact.

[0025] The dredging mechanism includes a dredging pipe 21 and a water reservoir 23. One end of the dredging pipe 21 is connected to the water inlet pipe 11, and the end of the dredging pipe 21 away from the water inlet pipe 11 is connected to the water outlet pipe 12. The dredging pipe 21 is provided with a first electric valve 22, and the first electric valve 22 is connected in series with the circuit of the sewage pump 25. The sewage pump 25 and the first electric valve 22 are started and stopped synchronously. A first drainage pipe 24 is connected to the side wall of the water reservoir 23. The end of the first drainage pipe 24 away from the water reservoir 23 is connected to the water outlet pipe 12. A second electric valve 241 is provided on the first drainage pipe 24. The second electric valve 241 is connected in series with the circuit of the rainwater pump station body 1, and the rainwater pump station body 1 and the second electric valve 241 are started and stopped synchronously.

[0026] The dredging mechanism also includes a sewage pump 25, which adopts a QW submersible pump with good corrosion resistance. The water inlet of the sewage pump 25 is fixedly connected to a first water pipe 26, and the end of the first water pipe 26 away from the sewage pump 25 is connected to the water reservoir 23. The water outlet of the sewage pump 25 is fixedly connected to a second water pipe 27, and the end of the second water pipe 27 away from the sewage pump is connected to the water inlet pipe 11.

[0027] The functional principle of the present invention can be explained through the following operation mode: municipal rainwater is drained to the water inlet pipe 11 through the first drainage pipe 111, the power of the rainwater pump station main body 1 is turned on, the second electric valve 241 is started synchronously, and the rainwater pump station main body 1 works to discharge the rainwater in the water inlet pipe 11 to the outlet pipe 12 for removal, and part of the rainwater enters the reservoir 23 through the second drainage pipe 24. The silt impurities in the rainwater are isolated in the water inlet pipe 11 by the filter plate. After the drainage work is completed, the power of the rainwater pump station main body 1 is turned off, the second electric valve 241 is closed synchronously, the power of the sewage pump 25 is turned on, the first electric valve 22 is opened synchronously, and the sewage pump 25 drains the rainwater in the reservoir 23 into the water inlet pipe 11. The rainwater flushes the silt in the water inlet pipe 11 to the outlet pipe 12 through the dredging pipe 21 and discharges it.
