[0035] See also Figures 1 to 5 A rooftop rainwater collection and utilization structure in this embodiment includes a drainage pipe 1 installed on the roof and extending to the ground, a purification installation tube 2, a water pipe 3, a water reservoir 4 and a fixed support seat 17.

[0040] The diameter of the installation cylinder 6 is equal to the inner diameter of the purification installation cylinder 2 to prevent impurities from being discharged from the gap. The ultrafiltration membrane 7 blocks the bottom opening of the installation cylinder 6, and the filter screen 10 blocks the top opening of the installation cylinder 6.

[0041] In this embodiment, a switch touch component is provided on the water purification and filtration component.

[0042] Among them, an installation groove is opened at the bottom of the plugging seat 11. A number of elastic telescopic rods 13 are installed in the installation groove. A positive contact head 12 is fixedly installed in the installation groove. A sealing block 14 for plugging and sealing the installation groove is fixedly installed between the bottoms of the elastic telescopic rods 13. A negative contact head 28 is fixedly installed at the top of the sealing block 14.

[0043] The elastic telescopic rod 13 is composed of a spring and a telescopic rod sleeved and fixed at both ends. When the elastic telescopic rod 13 is in a compressed state, the positive contact head 12 is in contact with the negative contact head 28, and the lower surface of the sealing block 14 is flush with the lower surface of the plugging seat 11.

[0044] It should be noted that the switch touch component includes a plugging seat 11 fixedly installed at the top of the installation cylinder 6 to plug the top opening of the purification installation cylinder 2 and a control chassis 15 fixedly installed on the front surface of the purification installation cylinder 2.

[0045] In this embodiment, a lifting component is provided between the water purification and filtration component and the fixed support seat 17.

[0046] The lifting component includes a hydraulic push rod 5 fixedly installed at the top of the fixed support seat 17. A moving rod 16 that passes through the purification installation cylinder 2 and is fixedly installed with the installation cylinder 6 is fixedly installed at the push rod of the hydraulic push rod 5.

[0047] In this embodiment, a flushing mechanism is provided outside the purification installation cylinder 2.

[0048] The flushing mechanism includes a number of through holes 26 opened outside the installation cylinder 6, a through hole 18 opened outside the installation cylinder 6, a pipeline 19 fixedly installed inside the installation cylinder 6 and communicated with the through hole 18, and a water storage seat 23 fixedly installed on the right side of the purification installation cylinder 2.

[0049] Among them, a water pump 24 is connected to the right side of the water storage seat 23. A water outlet pipe 25 communicated with the purification installation cylinder 2 is connected to the drainage port of the water pump 24. A number of spray heads 20 are connected to the bottom of the pipeline 19. A plugging rotary cover 21 is rotatably connected inside the spray head 20. A torsion spring 22 is fixedly installed between the plugging rotary cover 21 and the spray head 20. An isolation net 27 is installed in the through hole 26.

[0050] The isolation net 27 has the same diameter as the through hole 26.

[0051] The aperture of the isolation net 27 is smaller than the particle diameters of the quartz sand layer 8 and the activated carbon layer and larger than the aperture of the filter screen.

[0052] When the installation cylinder 6 is located at the uppermost position, the through hole 18 is docked and communicated with the water outlet pipe 25. The connection between the water pipe 3 and the purification installation cylinder 2 is located below the installation cylinder 6, and the connection between the drainage pipe 1 and the purification installation cylinder 2 is located above the installation cylinder 6.

[0053] The space between the water purification and filtration component and the switch touch component is used to store the filtered impurities. When the stored impurities are full, the impurities squeeze the switch touch component to be electrified and drive the lifting component to push out the water purification and filtration component from the purification installation cylinder 2 to discharge the stored impurities. At the same time, it cooperates with the flushing mechanism to flush the impurities of the water purification and filtration component in the purification installation cylinder 2 to ensure the filtration effect.

[0054] The hydraulic push rod 5, control chassis 15, positive contact head 12, negative contact head 28 and connecting wires of the present utility model form a series circuit, ensuring that a circuit is formed when the positive contact head 12 and the negative contact head 28 are in contact, enabling the hydraulic push rod 5 to work for one stroke of the expansion and retraction of the push rod. At the same time, the control chassis 15 is electrically connected to the water pump 24. The control chassis 15 is provided with an equipment controller and a storage battery to control the system power supply and operation of the overall equipment. It should be noted that the above principles are all prior arts, and the circuit design of the connecting wires does not affect the operation of the structure of the present utility model.

[0055] The working principle of the above embodiment is as follows:

[0056] The rainwater on the roof is discharged into the purification installation cylinder 2 through the arranged drainage pipe 1, so that the incoming rainwater flows through the installation cylinder 6 and is filtered by the combination of the filter screen 10, activated carbon layer 9, quartz sand layer 8 and ultrafiltration membrane 7. The filtered large-particle impurities accumulate on the top of the filter screen 10, and the small-particle impurities penetrate into the activated carbon layer 9 and quartz sand layer 8, realizing that the purified water flows into the reservoir 4 through the water pipe 3 for storage;

[0057] In addition, as rainwater continuously enters, the filtered impurities gradually accumulate until the space between the plugging seat 11 and the installation cylinder 6 is filled with impurities. Thus, the accumulated impurities push the sealing block 14 to move, driving the negative contact head 28 into contact with the positive contact head 12 to conduct electricity (the elastic telescopic rod 13 is compressed synchronously), ensuring that the negative contact head 28, the positive contact head 12, the hydraulic push rod 5, and the control chassis 15 form a circuit. The hydraulic push rod 5 is activated to push the installation cylinder 6 and the plugging seat 11 on the moving rod 16 to move upward as a whole, thereby pushing the stored impurities to move to the opening at the top of the purification installation cylinder 2 for discharge (after the stored impurities are discharged, the elastic telescopic rod 13 contracts and resets to drive the negative contact head 28 to separate from the positive contact head 12). At the same time, when the installation cylinder 6 moves to the topmost position, the water outlet pipe 25 is docked and communicated with the through hole 18. At this time, the set water pump 24 is activated to pump out the water in the water storage seat 23 and discharge it through the water outlet pipe 25. Utilizing the mutual connection between the water outlet pipe 25, the through hole 18, the pipeline 19, and the nozzle 20, the water enters the nozzle 20 and under the action of water pressure, the plugging rotary cover 21 is pushed to rotate and open, and the torsion spring 22 is distorted, so that the water sprays out from the nozzle 20 to wash the quartz sand layer 8 and the activated carbon layer 9. After the washing is completed, the torsion spring 22 resets to drive the plugging rotary cover 21 to rotate to block the opening of the nozzle 20 to prevent the entry of impurities. Furthermore, the fine impurities after cleaning are discharged to the outside through the isolation net 27 from the through hole 26. Thus, the overall device ensures the regular cleaning of the filtered impurities while ensuring the filtering effect of the filtering structure and improving the water storage efficiency.

[0058] All electrical components mentioned in the text are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed electrical connection technology is not elaborated in the text.
