[0040] Embodiment 1

[0041] As shown in Figure 1 Figure 10 The present application provides a green building roof drainage diversion and recycling system, which comprises a building component 1, a drainage component 2 installed around the building component 1, a flower watering component 3 installed on the drainage component 2, a positioning filter component 4 slidingly installed in the drainage component 2, an auxiliary rotating component 5 installed in the center of the drainage component 2, and a buffer filter component 6 slidingly installed at the bottom of the drainage component 2. Most of the building component 1, the drainage component 2, the flower watering component 3, the positioning filter component 4, the auxiliary rotating component 5 and the buffer filter component 6 are made of copper material, which can prevent the system from rusting.

[0042] Specifically, the building component 1 comprises a plurality of floors 103, and a flow-through flower watering flow-through opening is formed between each floor 103. The top end of each floor 103 is fixedly connected with a slope brick 102, and the top end of the slope brick 102 is fixedly connected with a building roof 101.

[0043] The drainage component 2 comprises a plurality of drainage pipes 201, which are fixedly installed on the outer side of the building roof 101 and the floor 103. The inner wall of the drainage pipe 201 is rotatably connected with two transmission wheels 205, the outer side of the two transmission wheels 205 is wound with a water-blocking guide block 203, the inner part of the drainage pipe 201 is fixedly connected with a transmission rack belt 204, and the side of the drainage pipe 201 away from the transmission wheel 205 is provided with a flow guide box.

[0044] ​The positioning type filtering assembly 4 comprises a filtering long plate 401, one side of the filtering long plate 401 is fixedly connected with a hollow sleeve block 402, the hollow sleeve block 402 is slidingly installed on the transmission rack strip 204, and the hollow sleeve block 402 is installed on the water-proof guide block 203; the top end of the filtering long plate 401 is fixedly connected with a plurality of springs 407, the top end of the plurality of springs 407 is fixedly connected with a filtering sleeve box 406, both sides of the filtering long plate 401 are rotatably connected with two groups of corresponding auxiliary wheels 405, the two groups of corresponding auxiliary wheels 405 are slidingly installed on the transmission rack strip 204, one side of the corresponding auxiliary wheel 405 is rotatably connected with a first sleeve rod 408, the first sleeve rod 408 is fixedly installed on the filtering long plate 401, one side of the filtering sleeve box 406 is fixedly connected with a second sleeve rod 409, and the second sleeve rod 409 is fixedly installed on the outside of the corresponding auxiliary wheel 405.

[0045] In this embodiment, the positioning filter assembly 4 further includes a toothed wheel 404, which is rotatably mounted on the inner wall of the hollow sleeve block 402. Two wheels 403 are rotatably connected to the inner wall of the hollow sleeve block 402. The two wheels 403 are meshed with the outer side of the water-proof guide block 203. The water-proof guide block 203 transmits friction between the wheels 403 and the toothed wheel 404, causing the hollow sleeve block 402 to move up and down under the guidance of the friction between it and the water-proof guide block 203. The auxiliary wheel assembly 5 includes two long sleeve rods 503. One long sleeve rod 503 is meshed with the outer side of the water-proof guide block 203, and the long sleeve rod 503 is rotatably connected to the inner wall of the drain pipe 201. Corresponding wheels 504 are fixedly connected to both sides of the long sleeve rod 503. The drain pipe 201... The interior has a hollow groove to prevent the positioning conveyor belt 501 and the corresponding rotating wheel 504 from contacting the rainwater above. The positioning conveyor belt 501 is wrapped around the side of the corresponding rotating wheel 504 away from the water-proof guide block 203. An auxiliary wheel 502 is wrapped around the inner wall of the positioning conveyor belt 501. The auxiliary wheel 502, the positioning conveyor belt 501, the long sleeve rod 503 and the corresponding rotating wheel 504 are located in the hollow groove. A forward and reverse motor connected to a transmission wheel 205 drives the transmission wheel 205 to rotate. The transmission wheel 205 relies on the water-proof guide block 203 for transmission movement. When the water-proof guide block 203 drives the filter plate 401 to move downward through the hollow sleeve block 402, the rainwater is gradually filtered and transmitted downward along the filter plate 401. A large amount of dust and sand is blocked by the filter plate 401. When the filter plate 401 slides along the water-proof guide block 203, the middle position of the long sleeve rod 503 is located inside the transmission rack belt 204 and can contact the corresponding auxiliary wheel 405 on the side away from the transmission wheel 205. When the two are in contact, the filter housing 406 and the second sleeve rod 409 both have corresponding teeth on their surfaces. The filter housing 406 is guided by the teeth of the corresponding auxiliary wheel 405 and driven by the second sleeve rod 409 to deflect the filter housing 406 to the side away from the transmission wheel 205. Under the limit of the spring 407, the deflection positioning distance is reduced, and most of the garbage is piled up together by the inclined position of the filter housing 406 and gravity. The absorbent material is sticky, and after accumulation, the waste is piled to one side to prevent the filter screen from clogging. At the same time, when the filter plate 401 moves upward via the transmission wheel 205, the filter housing 406 returns to its original position. The multiple stretched springs 407 guide the filter housing 406 to vibrate slightly, shaking out the dust in the filter screen holes, further improving the purification and flow of rainwater. Since the filter housing 406 can move up and down, when it moves to the center, on a sunny day, staff can be positioned at the corresponding floor 103 to open the middle hatch of the drainage pipe 201 to collect and clean the waste inside the positioning filter assembly 4 and the drainage assembly 2, extending the service life of the device.

[0046] Example 2

[0047] like Figure 1 and Figure 8 As shown, based on Embodiment 1, the buffer filter assembly 6 includes a hollow sleeve 603. A long cylindrical filter plate 605 is fixedly connected to the top of the hollow sleeve 603. The hollow sleeve 603 and the long cylindrical filter plate 605 are slidably installed on the transmission rack belt 204. Rainwater flowing from the top of the building roof 101 flows through various drainage pipes 201. The rainwater filtered by the positioning filter assembly 4 is now free of large impurities and flows into the hollow sleeve 603. The hollow sleeve 603 transmits the water flow through the surrounding water pipes to the collection area in the drainage pipes 201. At the same time, it is transmitted to the watering assembly 3 through a water pump to water the floor 103 corresponding to the location, thus completing the reuse of water resources.

[0048] Example 3

[0049] like Figure 5 - Figure 8 As shown, based on the above embodiment 1 or embodiment 2, a support block 601 is fixedly connected to one side of the hollow sleeve 603. The support block 601 is fixedly installed on the outside of the water-proof guide block 203. A folded filter plate 607 is hinged to the side of the long cylindrical filter plate 605 near the water-proof guide block 203. The side of the long cylindrical filter plate 605 away from the water-proof guide block 203 is hinged to the long cylindrical filter plate 605. There are two folded filter plates 607, and the two folded filter plates 607 are hinged together.

[0050] In this embodiment, the top of the folded filter plate 607 is fixedly connected with the same number of sponge filter plates 604, and the top of the long cylindrical filter plate 605 is fixedly installed with a hollow block 606. The folded filter plate 607 is slidably installed inside the hollow block 606. As the filtered water above the positioning filter assembly 4 drips down, and as the support block 601 moves upward with the water-proof guide block 203, the water flow gets closer and closer to the sponge filter plate 604. At this time, the falling water flow is buffered by the characteristics of the sponge material of the sponge filter plate 604, reducing the noise caused by drainage and improving the comfort of people in green buildings. At the same time, the brushes installed on the sides of the sponge filter plate 604 and the sides of the folded filter plate 607 rise along the transmission rack belt 204, scraping off and absorbing the rainwater stuck in the gaps of the transmission rack belt 204, thereby improving the water recovery rate.

[0051] Example 4

[0052] like Figures 5-8As shown, based on the above embodiment 1 or embodiment 3, a sealed long tube 611 is fixedly connected to one side of the folded filter plate 607, a movable push block 614 is slidably connected inside the sealed long tube 611, a conductive airbag 613 is fixedly connected to one side of the movable push block 614, the conductive airbag 613 is fixedly installed on the sealed long tube 611, and a pressure block 612 is fixedly installed on the top of the conductive airbag 613, and the pressure block 612 is slidably installed inside the sealed long tube 611.

[0053] In this embodiment, the drainage component 2 also includes a guide-type hollow sleeve block 202, which is fixedly installed on the drainage pipe 201. A baffle 206 is fixedly connected inside the transmission rack belt 204. A telescopic rod 602 is fixedly connected to the top of the support block 601. A pressure rod 608 is fixedly installed at the bottom of the sealed long pipe 611. A buffer spring 609 is fixedly installed between the pressure rod 608 and the telescopic rod 602. As the sponge filter plate 604 and the water-proof guide block 203 move upward, the support block 601 drives the sealed long pipe 611 to move towards the baffle 206. The pressure block 612 is compressed, and the internal gas moves into the sealed long pipe 611. The gas compresses the conduction airbag 613, causing the conduction airbag 613 to be compressed and conduct the movable push block 614 along the sealed long pipe 611. The movable push block 614 moves outward along the hollow block 606 by pushing the folded filter plate 607 towards the center. Guided by the two bidirectional hinge rods 610, the two folded filter plates 607 fold towards the center along their connecting edge. As the support block 601 continues to move upward, the sealed long tube 611 slides in the telescopic rod 602 through the pressure rod 608 and remains in its original position. The movable push block 614 remains in an outward sliding state. Under the push of the support block 601 and the guidance of the hollow part of the guide hollow sleeve block 202, the sponge filter plate 604 folds the folded filter plate 607 further, and the water flow on the surface of the sponge filter plate 604 is scraped off, causing the water flow to enter the hollow sleeve box 603 from the lower part, thereby further improving the water collection efficiency, avoiding excessive water absorption by the sponge, and reducing the noise reduction effect.

[0054] The above specific embodiments are merely several optional embodiments of the present invention.
