Technical Field

[0001] The present invention relates to the technical field of rainwater recycling in sponge cities, and in particular to a rainwater recycling device on a roof of a sponge city and a use method thereof. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. The internationally accepted term is "low-impact development rainwater system construction". When it rains, it absorbs, stores, infiltrates and purifies water, and when needed, the stored water is "released" and used.

[0003] When it rains, rainwater from the roof is generally discharged into the sewer through water pipes or collected uniformly. The collected rainwater is generally used to irrigate the green belts later. The rainwater collected in this way requires manual transportation of the rainwater and manual observation of whether the green belts are short of water, which increases the workload of rainwater use.

[0022] See also Figure 2-7 , the rectangular hole 302 is connected to the rectangular pipe 201, and a plurality of holes are provided in the middle of the inclined plate 203, so that fallen leaves and other debris mixed in the rainwater can be removed by the inclined plate 203. Cotton pieces are sandwiched between the two first drain plates 504 and the second drain plate 703, and the traction rope 512 passes through the L-shaped tube body 506, so that the rubber plug 502 is not easily blocked by air pressure during the rising process, and mud is not easy to enter the shell 501, and the traction rope 512 can be protected by the L-shaped tube body 506. The end of the tension spring 510 away from the baffle 509 is fixedly connected to the slide 508, and the area of ​​the baffle 509 is larger than the semicircular hole 511, so that the tension spring 510 can pull the baffle 509 to reset, and the baffle 509 can block the semicircular hole 511.

[0023] See also Figure 5-9The lower end of the support pipe 6 is connected to the chute 508, and the upper end of the support pipe 6 is connected to the lower end of the water tank 1, so that rainwater can enter the chute 508 through the support pipe 6, and rainwater in the water tank 1 can enter the support pipe 6. The trigger module of the sensing module 702 is installed at the lower end of the buoyancy block 704, and the sensing module 702 is electrically connected to the servo motor 709, so that when the lower end of the buoyancy block 704 contacts the sensing module 702, the sensing module 702 can be triggered to send an electrical signal, and the sensing module 702 can control the rotation of the servo motor 709. The cross section of the semicircular stopper 710 is half of the cross section of the drainage cylinder 706, and the semicircular stopper 710 can block the water outlet 708 and the transverse pipe 705, so that the semicircular stopper 710 can control whether the water outlet 708 and the transverse pipe 705 are turned.

[0024] When in use, the irrigation structure is buried under the soil of the green belt. When it rains, rainwater falls from the roof through the rectangular hole 302 into the rectangular pipe 201, and the rainwater passes through a plurality of inclined plates 203. Under the action of the holes of the inclined plates 203, the impurities mixed in the rainwater are purified and filtered, and the rainwater enters the water storage tank 1 and is stored; When the amount of water inside the irrigation structure is insufficient, the trigger module at the bottom of the buoyancy block 704 contacts the sensing module 702. The sensing module 702 sends an electrical signal to control the servo motor 709 to control the semicircular stopper 710 to rotate to the side away from the horizontal tube 705. At the same time, the rubber plug 502 moves downward under the action of the compression spring 513. The rubber plug 502 pulls the baffle 509 to move to the side close to the L-shaped tube body 506 through the compression spring 513. At this time, the baffle 509 no longer blocks the semicircular hole 511, and rainwater passes through the semicircular hole 511 from the support pipe 6 into the main pipe 4, and the rainwater flows out through the water outlet 708. Water enters the water storage tank 701 through the transverse pipe 705. When the water storage tank 701 collects enough rainwater, the buoyancy block 701 rises to separate the trigger module and the sensing module 702. The sensing module 702 sends an electrical signal to control the servo motor 709 to control the semicircular block 710 to rotate to the side close to the transverse pipe 705. The semicircular block 710 blocks the water outlet 708. After that, rainwater enters the housing 501 through the connecting pipe 503. The rainwater pushes the rubber plug 502 to move upward. The rubber plug 502 no longer pulls the traction rope 512. Under the action of the tension spring 510, the baffle 509 blocks the semicircular hole 511 again. When it does not rain for a long time, the soil outside the water tank 701 dries up, and the rainwater inside the water tank 701 evaporates through the second leakage plate 703. When the rainwater inside the water tank 701 evaporates to a certain extent, the buoyancy block 704 descends to make the trigger module and the sensing module 702 contact again. The sensing module 702 sends an electrical signal to control the servo motor 709 to drive the semicircular stopper 710 to rotate to the side away from the horizontal tube 705. At this time, the semicircular stopper 710 no longer blocks the water outlet 708. Then, under the action of the compression spring 513, the rubber plug 502 moves downward, and the rubber plug 502 pulls the baffle 509 through the traction rope 512 to no longer block the semicircular hole 511. The rainwater stored in the water tank 1 flows out through the supporting pipe 6 and the main pipe 4 through the water outlet 708, and at the same time, the rainwater enters the water tank 701 through the transverse pipe 705. Before the rainwater in the water tank 701 is stored enough to float the buoyancy block 704, the rainwater irrigates the surrounding soil through the water outlet 708. After the buoyancy block 704 floats, the induction module 702 controls the servo motor 709 again so that the semicircular block 710 blocks the water outlet 708. The rainwater enters the shell 501 again to lift the plug 502. Under the action of the tension spring 510, the baffle 509 blocks the semicircular hole 511 again, completing the irrigation of the green belt soil. The rainwater is collected by the water tank 1, and the drainage device 7 controls the irrigation structure to irrigate the green belt soil after the moisture content of the green belt soil is reduced to a certain extent, thereby reducing the workload of using rainwater.

[0025] The present invention collects rainwater through a water storage tank, and the drainage device controls the irrigation structure to irrigate the soil of the green belt after the moisture of the soil in the green belt is reduced to a certain level, thereby reducing the workload of using rainwater.

[0026] The drainage device can automatically irrigate the surrounding soil when there is no rain for a long time and the soil is dry.
