Description

Technical Field

[0002] In cases where the water level at the outlet of the rainwater pipe is high, rainwater cannot be discharged by gravity, or the highest water level is higher than the ground level of the drainage area, a rainwater pumping station needs to be installed before the outlet of the rainwater pipe to lift the rainwater and discharge it.

[0003] In existing technology, rainwater pumping stations connect an external primary filter cylinder via a pipeline. After initial filtration, the rainwater flows through the pipeline into the pumping station, where a booster pump removes the water. This structure requires external pipelines and the primary filter cylinder, significantly increasing costs and occupying considerable space. Furthermore, it necessitates digging a separate pit to house the primary filter cylinder, greatly complicating its operation. Therefore, an improved technology is urgently needed to address the aforementioned problems in existing technologies. Utility Model Content

[0027] like Figure 3 As shown, the primary filter assembly 7 includes a tube body 701 and a primary sieve plate 702. Several parallel tube bodies 701 are welded to the upper surface of the primary sieve plate 702. The primary sieve plate 702 is densely covered with sieve holes.

[0028] like Figure 4 As shown, the secondary filtration assembly 8 includes a first ring body 801 and a secondary filter screen 802. The secondary filter screen 802 is provided inside the first ring body 801. The first ring body 801 is connected to the cylindrical seat 13 by bolts.

[0030] Installation method and operating principle: The inner cylinder 2 is connected to the base 4 at the bottom of the outer cylinder 1 via the base plate 20 and bolts. Several cylindrical seats 13 are provided at the bottom of the inner cylinder 2, and secondary filter components 8 are installed at the outer ends of each cylindrical seat 13. The primary filter component 7 is supported inside the inner cylinder 2 by an annular support plate 12. The water inlet pipe 11 passes through the inner wall of the outer cylinder 1 and is welded to the cylinder wall of the inner cylinder 2, allowing the water inlet pipe 11 to communicate with the interior of the inner cylinder 2. Simultaneously, the water inlet pipe 11 is welded and sealed to the corresponding position on the outer cylinder 1. Several support rods 21 are welded between the outer cylinder 1 and the inner cylinder 2. Then, a ladder 16 is installed on the inner wall of the outer cylinder 1, and a grille 5 is supported on the support rods 21. A notch is left at the location of the ladder 16 in the grille 5, which facilitates cooperation with the ladder 16 and allows a cover plate 18 to be hinged at the notch.

Rainwater enters the inner cylinder 2 through the inlet pipe 11 and undergoes initial filtration through the pipe 701 and primary sieve plate 702 of the primary filter assembly 7, trapping larger impurities. It then undergoes secondary filtration through the secondary filter screen 802 at the bottom of the inner cylinder 2 before flowing into the space between the outer cylinder 1 and the inner cylinder 2. When the water level is too high (monitored by a level sensor), the booster pump 6 starts, and the rainwater is discharged from the outlet pipe 10 through the booster pump 6 and connecting pipe 14. This utility model has a reasonable structure. An inner cylinder 2 is set inside the outer cylinder 1, and a primary filter component 7 is set inside the inner cylinder 2. A secondary filter component 8 is set at the bottom of the inner cylinder 2 through several cylindrical seats 13 for water outlet.

At the same time, the multiple cylindrical seats 13 and the secondary filter components 8, with a multi-channel structure, are not easy to clog. An observation port 9 is also set on the upper surface of the cylinder cover 3 through the raised seat 17. Through the observation port 9, it is possible to check whether the primary filter component 7 of the inner cylinder 2 has accumulated too many impurities, which greatly improves convenience.
