In the contact state, the cleaning plate members 601 are always in contact with the inner and outer walls of the filter cartridge 502 during the rotation of the filter cartridge 502 to achieve the scraping and cleaning operation.

At this time, one group of the blade plates 703 is located at the trapezoidal structure below the accommodation space 101, i.e., the water flow enters from the left side. When the rainwater enters, the debris is blocked below the baffle 104, which plays a role in classifying the debris. The first rotary disc 5 is rotated to drive the debris to enter the floating member 8 for temporary storage. However, the debris is easy to fall off the blade plates 703.

EIGHTH EMBODIMENT

[0079] In combination with Figure 4 and Figure 21 It is shown that the left side of the case 1 is provided with a water storage space 9, which can store part of rainwater, and the water storage space 9 is provided with a water outlet channel communicated with the containing space 101, which is used for flushing the storage channel 103; the rear of the case 1 is provided with a temporary storage box communicated with the discharging pipe 403, which is used for storing sundries such as branches and plastic bottles, meanwhile, the lower part of the storage channel 103 is provided with a sand storage space 10, and a lifting auger 11 is installed at the discharge port of the sand storage space 10, which is used for lifting the sand to a suitable position to meet the demand of automatic operation; meanwhile, the technical solution can also increase a water pump and a rainwater storage tank, which are used for storing the rainwater discharged from the water outlet and the unblocking member 3, to realize recycling, which can be used for moisturizing and dust reduction of the pavement, and the cement is stirred after being filtered, which saves the consumption of water resources and reduces the construction cost.

[0080] Working principle:

[0081] For large rainfall, the unblocking piece 3 is displaced upward, the closure of the storage channel 103 is released, and the rainwater flows in the process. The filter cylinder 502 is in a rotating state, and the rainwater is discharged from the water outlet 501 after passing through the filter cylinder 502. At the same time, in the rotating process, the cutting piece 7 can cut and cut the large floating materials on the water surface through the extrusion cutting channel 102, and the sand is deposited in the storage channel 103 under the action of gravity. The classification and recycling of the impurities are realized. The cut impurities fall on the floating pushing piece 8 and are conveyed to the right side of the containing space 101 for storage. Then the cut impurities are discharged through the discharge assembly 4, realizing integrated processing operation. Relying on the rotation of the filter cylinder 502, the filtering area is continuously adjusted to ensure the filtering efficiency. At the same time, the filter cylinder 502 can also adhere the leaves and other impurities on the surface and transmit them to the right side of the containing space 101 during the rotating process, realizing the discharge operation. When the sand in the storage channel 103 accumulates more, the unblocking piece 3 is displaced downward to close the storage channel 103. After the sand is discharged, the unblocking piece 3 is opened again, and the sand discharge operation can be completed without stopping the operation, meeting the requirement of continuous operation.

[0082] For small rainfall, the water flow is small, and the impurities are relatively less, so full-power drainage operation is not required. At this time, the position of the blade 703 on the first rotating disc 5 is adjusted, so that one group is located at the left side of the trapezoidal structure of the containing space 101. When the water flow passes through, it forms a barrier to large impurities, and the sand in the rainwater is deposited on the left side or the right side of the unblocking piece 3. The water flow enters through the drain hole 302 and is discharged through the water outlet pipe 301. The water outlet pipe 301 is connected to the water pump to generate negative pressure adsorption, meeting different use conditions. When the sand accumulates more, the storage channel 103 can be opened to discharge.

[0083] In summary, the present application meets the drainage operation under different conditions, and completes the classification and collection of impurities during the rainwater discharge process. At the same time, the impurities mixed in the discharged rainwater are avoided, the pump body is not damaged, the whole rainwater is integrated processed, and it is suitable for the drainage operation environment of deep foundation pit. The traditional blockage condition is effectively solved. When the water quantity is insufficient to completely cover the filter cylinder, the filter cylinder 502 is in a rotating state in the working state, the filtering area can be flexibly changed to ensure the filtering effect, and the cleaning plate 601 can be used to clean the filter cylinder 502 in time to avoid the blockage. Under the condition of sufficient water quantity, the filtering effect of the filter cylinder 502 can also be maintained by the cleaning plate 601 to meet the long-term normal operation, the operation is stable, and it can be applied to both small and large rainfall operation environments, further reducing the limitation of use requirements. It can also be popularized to the deep foundation pit construction operation in the northern area with less rainwater.

[0084] It should be understood that the above detailed description and specific examples, while indicating preferred embodiments of the application, are given by way of illustration only, since various changes and modifications within the spirit and scope of the application will become apparent to those skilled in the art from this detailed description.
