A first through hole 6311 for the first support rod 636 to pass through is formed inwardly on the upper surface of the first connecting block 631. An annular groove 6312 arranged in an annular shape is formed in the side wall of the first through hole 6311, a sealing ring 6313 abutted to the first connecting block 631 is arranged in the annular groove 6312, a second through hole 6314 for the first support rod 636 to pass through is arranged in the middle of the sealing ring 6313, and when the first support rod 636 is laid, a space for the first support rod 636 to move is reserved above the first support rod 636.
When the rainfall is more abundant, when the first water collecting well 2, the second water collecting well 5 and the water seepage well 6 are full of rainwater, the rainwater starts to flow into the water seepage well 6, when the liquid level in the water seepage well 6 exceeds the seventh diversion pipe 62, the liquid in the water seepage well 6 starts to flow into the seventh diversion pipe 62, the rainwater in the seventh diversion pipe 62 flows into the first connecting block 631, and the rainwater below the rubber plate 635 generates thrust on the rubber plate. When rainwater continues to flow into the weep well 6 and the liquid level in the weep well 6 exceeds the seventh flow guide pipe 62 to a certain extent, the rubber plate 635 is pushed by water flow to move upwards and drive the spring 6351 to compress, when the rubber plate 635 is separated from the abutting state with the second baffle 634, the rainwater enters the right part of the first cavity 632 from the bottom of the rubber plate 635 and enters the connection part of the seventh flow guide pipe 62 and the sewer 64 through the right part of the first cavity 632, so that the redundant rainwater enters the sewer 64, and the water storage pressure in the first water collection well 2, the second water collection well 5 and the weep well 6 is relieved. When there is no rainwater, the liquid level in the weep well 6 slowly drops, and at this time, the rubber plate 635 moves downward under the elastic force of the spring 6351, and when the rubber plate 635 abuts against the first baffle 633, the rubber plate 635 blocks the seventh draft tube 62, thereby blocking the backflow of the sewage in the sewer 64.
Referring to fig. 5 and 6, a connection rod 637 is fixedly connected to an end of the first support rod 636 away from the first connection block 631, and when the connection rod 637 is laid, a space for the connection rod 637 to move is reserved above the connection rod 637. The middle part of the fifth guide pipe 51 is connected with a second connecting block 52, a second die cavity 521 is arranged inside the second connecting block 52, and the fifth guide pipe 51 is communicated with the second die cavity 521. A vertically arranged insertion groove 53 is arranged in the second connecting block 52, a third baffle 531 is arranged in the insertion groove 53, the third baffle 531 is inserted into the insertion groove 53 in a sliding manner, and the upper surface of the third baffle 531 is fixedly connected with the connecting rod 637.
When the third baffle 531 is completely disposed inside the inserting groove 53, the fifth draft tube 51 is connected back and forth, and the rubber plate 635 abuts against the first baffle 633 and serves to block the seventh draft tube 62. When the rainwater is abundant, when the landscape pool 4, the first water collecting well 2, the second water collecting well 5 and the water seepage well 6 are full of water, the standing effect of the landscape pool 4 and the second water collecting well 5 on the water can be influenced, and impurities carried in the rainwater can easily enter the second water collecting well 5. When the liquid level in the weep well 6 exceeds the seventh draft tube 62 and the rubber plate 635 moves upward under the driving of the water flow, the rubber plate 635 drives the support rod, the connecting rod 637 and the third baffle 531 to move upward together, and when the rubber plate 635 is separated from the abutment with the second baffle 634, the third baffle 531 rises to the position completely separating the fifth draft tube 51. Therefore, the fifth guide pipe 51 is completely separated while the seventh guide pipe 62 is conducted, and the probability that impurities carried in rainwater flow into the first water collecting well 2 through the fifth guide pipe 51 after entering the second water collecting well 5 when the rainwater is abundant is further reduced.
Referring to fig. 3 and 4, the ground is further provided with an annular green belt 7, the bottom of the water collecting tower 3 is fixedly communicated with a drainage pipeline 32, one end of the drainage pipeline 32, which is far away from the water collecting tower 3, is fixedly communicated with a first water supply pipe 33, one end of the first water supply pipe 33, which is close to the water collecting tower 3, is provided with a first valve 331, and one end of the first water supply pipe 33, which is far away from the drainage pipeline 32, is fixedly communicated with a watering pipeline 332.

When the green belt 7 needs to be irrigated, the first valve 331 is opened, rainwater collected in the water collection tower 3 flows through the drainage pipeline 32, the first water supply pipe 33 and the irrigation pipeline 332 in sequence under the action of pressure, and is finally sprayed out by the irrigation nozzle 334, irrigation of the green belt 7 is completed, and recycling of the rainwater is achieved.
Referring to fig. 3 and 4, one end of the drainage pipe 32, which is far away from the water collecting tower 3, is further fixedly communicated with a second water supply pipe 34, one end of the second water supply pipe 34, which is close to the water collecting tower 3, is provided with a second valve 341, one end of the second water supply pipe 34, which is far away from the drainage pipe 32, is communicated with a flushing pipeline 342, the flushing pipeline 342 is arranged above the second drainage channel 17 and is annularly arranged, the bottom of the flushing pipeline 342 is communicated with a plurality of flushing pipelines 343, and the flushing pipelines 343 extend into the second drainage channel 17 and abut against the top of the second drainage channel 17.
When the interior of the second drainage channel 17 needs to be flushed, the second valve 341 is opened, rainwater collected in the water collecting tower 3 sequentially flows through the drainage pipeline 32, the second water supply pipe 34 and the flushing pipeline 342 under the action of pressure and is finally sprayed out from the flushing pipeline 343, the flushed rainwater carries impurities to enter the landscape pool 4 through the third flow guide pipe 171 for standing, the flushing effect on the second drainage channel 17 is achieved, and the probability of blockage of the second drainage channel 17 is reduced.
The implementation principle of the water circulation system for the sponge city in the embodiment of the application is as follows:
when the amount of rainwater is small, after entering the canal 1 through the first seepage holes 12 on the cover plate 11, the rainwater firstly passes through the seepage and drainage device 14, then enters the first drainage channel 13, and enters the water collecting well through the first diversion pipe 15 communicated with the side wall of the first drainage channel 13, and when the amount of rainwater is large, the rainwater on the top of the canal 1 flows into the second drainage channel 17 through the second diversion pipe 16, flows into the landscape pool 4 through the third diversion pipe 171, and finally flows into the second water collecting well 5 through the fourth diversion pipe 41.
When the rainfall is abundant, the rainwater begins to flow into first connecting block 631 from seventh honeycomb duct 62 by infiltration well 6, rubber sheet 635 upwards moves under the effect of rivers, thereby when rubber sheet 635 is promoted by rivers and breaks away from the butt with first baffle 633, the rainwater is through getting into first cavity right part from rubber sheet 635 bottom, and get into seventh honeycomb duct 62 and sewer 64 connected portion via first cavity right part, when rubber sheet 635 drove first bracing piece 636 upward movement, first bracing piece 636 drove connecting rod 637 upward movement, connecting rod 637 drove third baffle 531 upward movement, third baffle 531 cuts off fifth honeycomb duct 51.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
