Referring to fig. 1 to 5, when raining, rainwater enters the water collection tube 2 from the nozzle grate 21, and the nozzle grate 21 shields impurities from the outside, but the outer surface of the nozzle grate 21 is easily blocked by the impurities. At this time, when rainwater enters the water collection tube 2, the driving assembly 4 works, the driving assembly 4 rotates the driven shaft 211 through the connecting piece 3, and the abutting ring 212 and the scraping strip 22 fixedly connected to the abutting ring 212 rotate along with the driving assembly 4. When the scraping strip 22 rotates, impurities on the outer surface of the water gap grate 21 can be cleaned, so that rainwater can normally enter the water collection barrel 2 through the water gap grate 21. Thereby reducing the likelihood of blockage of the irrigation system. After the rainwater enters the water collection cylinder 2, the rainwater reaches the water collection tank 9 through the water collection main pipe 14, so that the rainwater is collected, the subsequent constructed wetland 1 is irrigated, and the rainwater is recycled.

Referring to fig. 2 and 4, since the irrigation system is disposed on the green land of the park, soil flows into the water collecting cylinder 2 along with rainwater during raining, passes through the filter cone 6, and then is collected into the settling chamber 72 in the slag collecting box 7 through the screw auger 82, and enters the slag collecting box 7 along with rainwater. And a slag trap 71 fixedly coupled to the slag collection bath 7 separates soil. After sedimentation, when the water level passes over the slag trap 71, it flows into the overflow chamber 73, and after passing through the overflow pipe 141, the water is collected in the water collecting main 14 and then flows into the water collecting tank 9.

Referring to fig. 1 and 2, a placement opening 91 is formed in the water collecting tank 9, a screw cap 911 is detachably connected to the placement opening 91, and as other liquid impurities exist in rainwater, the rainwater in the water collecting tank 9 may be smelly, and the placement opening 91 can perform simple disinfection and cleaning in the water collecting tank 9. Be equipped with water pump 92 on the catch basin 9, can dismantle on the water pump 92 and be connected with water pumping pipe 921, be equipped with a plurality of branch water pipes 13 on the constructed wetland 1, and can dismantle on the branch water pipe 13 and be connected with a plurality of shower nozzles 131, shower nozzles 131 set up along the route equidistance of branch water pipe 13.

Referring to fig. 1 and 2, when the constructed wetland 1 needs to be irrigated, the water pump 92 is started, rainwater in the water collecting tank 9 reaches each branch water pipe 13 through the water suction pipe 921 and then reaches the spray head 131 through the branch water pipe 13, so that the cyclic utilization of water resources is realized, and the utilization rate of the water resources is further improved.

The implementation principle of the park green land water storage irrigation system based on sponge city construction provided by the embodiment of the application is as follows:

when the downstorm or rainwater is collected, the rainwater enters the water collection cylinder 2 through the water gap grate 21. The gully grating 21 filters the rainwater for the first time, mainly as leaves.

When rainwater enters the water collection barrel 2, the rainwater firstly passes through the filtering cone barrel 6, and at the moment, the rainwater is filtered for two stages and mainly is soil. At this time, soil is retained in the filtering cone 6, and rainwater passes through the filtering holes of the filtering cone 6, through the flow guide pipe 5, and then reaches the inside of the rotating cone 41.

The mud reaches the slag filtering barrel 8 after passing through the filtering cone barrel 6, and then the impurities reach the settling chamber 72 in the slag collecting box 7 by the spiral auger 82 in the slag filtering barrel 8. After a lapse of a certain time. When the water level of the rainwater in the settling chamber 72 exceeds the slag trap 71, the rainwater in the settling chamber 72 flows into the overflow chamber 73, so that the rainwater in the overflow chamber 73 passes through the overflow pipe 141 to the water collecting main 14 and then flows into the water collecting tank 9. Thereby saving the water resource and further improving the utilization rate of the water resource.

When the rainwater reaches the flow guide pipe 5 after passing through the filtering cone 6, the diversion platform 51 in the flow guide pipe 5 makes the rainwater diffuse to the circumferential direction of the diversion platform, so that the rotation capacity of the rotating cone 41 is further improved. The spiral 411 pieces which are fixedly connected and are symmetrically arranged along the center of the axis of the rotary cone 41 further improve the rotary capacity of the rotary cone 41.

After the rainwater enters the rotary cone 41. Since the diameter of the large port of the rotary cone 41 is larger than that of the small port thereof and the diameter of the small port thereof is larger than that of the rotary branch pipe 42, the rotary cone 41 is rotated by potential energy generated when rainwater flows out of the rotary branch pipe 42 after flowing into the rotary cone 41. The driving shaft 44 fixedly connected in the rotary cone 41 rotates with the rotary cone, the connecting pieces 3 are fixedly connected on the driving shaft 44, and the connecting pieces 3 are three bevel gears 31 and meshed with each other. So that when the driving shaft 44 rotates, the driven shaft 211 and the driving shaft 81 also rotate. The connection between the three bevel gears 31 not only saves resources, but also avoids the influence of short circuits caused by rainwater due to conventional electric or pneumatic driving members, thereby reducing the risk of post-maintenance.

The balls 431 on the rotating ring 43 and the abutting hemisphere 241 reduce the friction force generated when the rotating cone 41 rotates. Further improving its performance.

When the rainwater flows out from the rotary branch pipe 42, the rainwater passes through the water collecting main pipe 14 and reaches the water collecting tank 9. When the constructed wetland 1 needs to be irrigated, the water pump 92 is started, so that rainwater in the water collecting tank 9 reaches each branch water pipe 13 through the water suction pipe 921, and then is uniformly sprayed onto the constructed wetland 1 through the spray heads 131. Thereby realizing the irrigation of the constructed wetland 1 and further improving the resource utilization rate.

The above embodiments are not intended to limit the scope of the application, so that the equivalent changes of the structure, shape and principle of the application are covered by the scope of the application.
