During operation, when rainwater acts on the surface of the second plate 53, the rainwater firstly gathers in the first cavity 533 formed at the position, close to the end part, of the upper surface of the second plate 53, the first cavity 533 is filled with the rainwater, so that the second plate 53 is driven by the gravity of the rainwater in the first cavity 533 to rotate at an accelerated speed, and the second plate 53 is further ensured to drive the first plate 52 to act on the upper surface of the filter screen 5 and the inner surface of the first channel 331 through the rotating shaft 51; in addition, in the process that the second plate 53 rotates downwards, rainwater accumulated in the first cavity 533 flows out and impacts the upper surface of the filter screen 5 along with the inclination of the first cavity 533, so that sediment impurities attached to the upper surface of the filter screen 5 are removed more completely under the impact action of the rainwater flowing out of the first cavity 533; along with the rainwater in chamber 533 flows out, and the impact that No. two boards 53 received is weakened, and No. two boards 53 are driven to reset by No. one board 52 under the effect of shell fragment 522 that resets this moment, and the process of repeating above-mentioned so makes adnexed silt on the filter screen 5 clear away more thoroughly, further guarantees the unblocked of filter screen 5.
As an embodiment of the present invention, a third groove 534 is uniformly formed on a portion of the upper surface of the second plate 53, which is located in the first cavity 533, and an end of the third groove 534 passes through an end of the second plate 53.
In operation, as the second plate 53 rotates downwards, the first cavity 533 begins to incline, and at this time, rainwater in the first cavity 533 flows along the third groove 534 arranged on the upper surface of the second plate 53, because the end of the third groove 534 passes through the end of the second plate 53, so that impurities attached to the end of the second plate 53 are effectively removed by rainwater flowing out through the third groove 534; and the rainwater flowing out along the third groove 534 forms a water flow which is concentrated to flow out through the end part of the second plate 53, when the end part of the second plate 53 is close to the upper surface of the filter screen 5, the concentrated water flow flowing out along the third groove 534 impacts the upper surface of the filter screen 5, so that the sediment impurities on the upper surface of the filter screen 5 are removed more thoroughly.
The specific working process is as follows:
after the sponge city encounters strong rain weather and lasts for a long time, a large amount of rain water accumulates on the green land of the sponge city, so that when the rain water flows on the surface of the green land and passes through the closing cover 31, the rain water is concentrated to pass through the interception rod 321 and flow into the water collection tank 3; at this time, the larger volume of the garbage sundries in the flowing rainwater is blocked by the interception rod 321 and can not flow into the water collection tank 3, so that the blockage of the water collection tank 3 caused by the larger volume of the garbage sundries is avoided; the middle part of the intercepting rod 321 is bent upwards and is higher than the upper surface of the water collecting tank 3, so that the garbage sundries attached to the intercepting rod 321 are repeatedly impacted by rainwater flowing on the ground surface because the garbage sundries are higher than the ground surface, and the garbage sundries are prevented from being attached to the intercepting rod 321 for a long time and preventing the rainwater from entering the water collecting tank 3; rainwater entering the water collecting tank 3 passes through the filter screen 5 and flows into the second groove 34, and rainwater in the second groove 34 flows into the water storage tank 1 through the water inlet pipe 2 and is stored; in the process that the rainwater passes through the filter screen 5, grass leaf fragments and silt attached to the rainwater in the flowing process are removed through the filtering action of the filter screen 5, so that excessive grass leaves and silt flowing into the water storage tank 1 are avoided, and bacterial viruses in the silt propagate massively in an oxygen-free environment under a long-term approximately closed environment and rot the grass leaves, so that the rainwater in the water storage tank 1 becomes black and smelly and is difficult to utilize; the upper surface of the filter screen 5 is in an upward-curved arc shape, so that a part of rainwater contacting with the filter screen 5 flows along the upper surface of the filter screen 5 and flows into the first passage 331, and when the rainwater flows along the upper surface of the filter screen 5, silt and grass debris attached to the upper surface of the filter screen 5 are brought to the first passage 331 and finally enter the collecting tank 33; therefore, the upper surface of the filter screen 5 is effectively cleaned, and the phenomenon that the filter screen 5 is blocked due to the fact that a large amount of silt and grass blade debris are accumulated on the upper surface of the filter screen 5 is avoided; when the rainwater flowing into the collecting tank 33 is excessive, the rainwater permeates through gaps among cobblestones stacked in the second passage 332 and flows into the water collecting tank 3 again, and silt and grass blade debris mixed with the rainwater flowing into the collecting tank 33 are blocked by the cobblestones stacked in the first passage 331, so that the silt and grass blade debris mixed with the rainwater flowing into the water collecting tank 3 are effectively collected into the collecting tank 33, the rainwater finally flowing into the water reservoir 1 is kept clean, and the rainwater in the water reservoir 1 can be stored for a longer time; when water is needed, workers in the sponge city can extract rainwater stored in the reservoir 1 through the water taking well 4 to irrigate plants on a green land or clean urban roads, so that the rainwater which originally threatens the urban safety can exert a beneficial effect, and the healthy development of the sponge city is further facilitated; since a large number of vegetation 6 are uniformly distributed above the green land, the rainwater is continuously hindered in the flowing process and flows in a wave shape, so that the flowing rainwater enters the collecting tank 33 and the first plate 52 is impacted continuously and variably; when the amount of inflow rainwater is large and the impact on the first plate 52 is large, the first plate 52 drives the bristles 521 on the end part to rotate downwards, and the upper surface of the filter screen 5 is scraped, so that silt impurities adhered to the filter screen 5 tightly are effectively removed under the scraping action, and the silt impurities removed under the action of the bristles 521 flow into the first passage 331 and enter the collecting tank 33 to be recovered along with the rotation of the end part of the first plate 52 towards the direction close to the first passage 331, and the smoothness of rainwater passing through the filter screen 5 is further ensured; when the amount of the inflowing rainwater is reduced and the impact effect is reduced, the first plate 52 is reset under the action of the reset elastic sheet 522, and the bristles 521 at the end part of the first plate 52 reversely act on the upper surface of the filter screen 5 while resetting and rotating, so that sundries attached to the filter screen 5 are removed more completely; the process is repeated, so that the filter screen 5 is kept clean under the repeated action of the first plate 52, and the normal work of the filter screen 5 is ensured; rainwater can smoothly pass through the water collecting tank 3 and finally flows into the reservoir 1 to be stored, and the phenomenon that the filter screen 5 is blocked to influence the rainwater collection is avoided; when rainwater acts on the surface of the second plate 53, the rainwater firstly gathers in the first cavity 533 formed by the upper surface of the second plate 53 close to the end part, and the rainwater fills the first cavity 533, so that the second plate 53 is driven by the gravity of the rainwater in the first cavity 533 to rotate at an accelerated speed, and further, the second plate 53 can drive the first plate 52 to act on the upper surface of the filter screen 5 and the inner surface of the first channel 331 through the rotating shaft 51; in the process that the second plate 53 rotates downwards, rainwater accumulated in the first cavity 533 flows out along with the inclination of the first cavity 533 and impacts the upper surface of the filter screen 5, so that sediment impurities attached to the upper surface of the filter screen 5 are removed more completely under the impact action of the rainwater flowing out of the first cavity 533; along with the rainwater in chamber 533 flows out, and the impact that No. two boards 53 received is weakened, and No. two boards 53 are driven to reset by No. one board 52 under the effect of shell fragment 522 that resets this moment, and the process of repeating above-mentioned so makes adnexed silt on the filter screen 5 clear away more thoroughly, further guarantees the unblocked of filter screen 5.
