Through these facilities, rainwater is guided into the storage pool for subsequent treatment and utilization. In the city, some rainwater wells are generally set up to drain or collect and recycle sewage or stormwater.

[0009] Further, the central shaft is fixed with a disc at the bottom of the slip ring, second electric push rods are fixed to the top of the disc on both sides, and the elongated ends of the second electric push rods are fixedly connected with the shaft ring.

[0010] Further, the upper end of the partition is provided with a water overflow groove on both sides, and the lower end of the partition is provided with a receiving groove, and the scraper is received in the receiving groove.

[0011] Further, the elongated end of the second electric push rod is fixed with a horizontal plate, an annular sliding groove is formed in the inner wall of the blocking frame, and the outer end of the horizontal plate is slidably connected in the sliding groove of the inner wall of the blocking frame.

Rainwater falls on the plastic cloth and is blocked by the adjacent two water spraying rods and guided by the water guide groove, and then flows out through the gap on the side of the plastic cloth close to the water collecting tank and falls into the water collecting tank to collect and filter the rainwater. The water spraying rod is connected with the underground water well through the external hose.

[0016] When it is necessary to reduce dust in the construction environment in daily life, the first electric push rod drives the top plate to move upward, the connecting rod pulls the water spraying rod to rotate to be vertical, the rotation of the central shaft is driven by the driving motor, the water spraying rod sprays dust around through the spray head in a rotary manner, and the rainwater is reused.

When a filter plate is blocked due to too much accumulated soil, the water level at the position will gradually rise until it reaches the overflow groove and flows into other chambers to be filtered by other chambers, so that the rainwater is not wasted.

[0019] The present application is connected with the cross plate and the blocking frame, so that when the second electric push rod elongated end drives the filter plate to move up and down, the cross plate can drive the blocking frame to move up and down synchronously, so that the filter plate moves out of the bottom of the water collecting tank, and the scraper is ready to clean the top of the filter plate, at this time, the blocking frame also releases the wrapping between the underground water well and the water collecting tank, and the exposed area can be used for the center shaft to drive the disc to rotate, and the scraper moves along the surface of the filter plate to clean the impurities and soil on the top of the filter plate, and falls from the gap of the blocking frame, when cleaning the filter plate, the two elongated ends of the two-way electric push rod drive the two cover plates to move along the socket, and the top area of the blocking frame is blocked, the position of the center shaft and the second electric push rod can be avoided by the cover plate slot, so that the two cover plates cannot be combined, and the two cover plates are combined into a disc to prevent the soil and impurities from falling into the underground water well during cleaning the filter plate, during the rainwater collection stage, the two-way electric push rod slides the two cover plates outward to open the blocking frame, and the filter plate is located at the bottom of the water collecting tank, and the blocking frame is also lifted to the bottom of the water collecting tank to wrap the area between the water collecting tank and the underground water well, so that the rainwater filtered by the water collecting tank is prevented from falling outside.
