[0002] Green building refers to buildings that maximize resource conservation throughout their entire life cycle, including energy, land, water, and materials conservation, while protecting the environment, reducing pollution, providing people with healthy, comfortable, and efficient living spaces, and coexisting harmoniously with nature. With the advancement of urbanization, more and more ground is covered by various green buildings and roads, preventing rainwater from infiltrating the ground and increasing the pressure on urban drainage systems. One way to solve this problem is to collect and reuse rainwater falling into the city, using it for landscaping, road cleaning, greening, toilet flushing, and car washing. One existing method for collecting rainwater involves collecting rainwater from the rooftops of green buildings in tanks. However, because the rooftops are surrounded by walls and exposed to the elements, they accumulate a large amount of dust and other substances. When rainwater falls, it flows into pipes and is filtered by filters. These filters become clogged over time and require regular cleaning, which has its limitations. Summary of the Invention

Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Reference Figures 1 to 8 A rainwater harvesting device for the rooftop of a green building includes at least one water tank 10 and an inlet pipe 2. A drain pipe 101 with a valve is provided on one side of the water tank 10. The device also includes: Drainage box 3 is installed on the top floor wall. It has a water inlet pipe 2 at the bottom and two openings 301 on one side. The support device includes two long swing rods 4 with one end in an L-shape and a lifting device. One end of the long swing rod 4 is rotatably connected to the two side walls of the opening 301. The lifting device is used to drive the other end of the long swing rod 4 to move up and down. The long swing rod 4 is provided with a through groove 401. The collection assembly includes a roller 5, a film 6, a stop 7, two short swing rods 8, a first pull rope 9, and a soft bag 11 filled with material. The roller 5 has a through-flow channel 501. One end of the film 6 is mounted on the wall of the channel 501, and the other end is connected to one end of the long swing rod 4. The stop 7 is mounted on the film 6. The two sides of the short swing rods 8 are rotatably connected to the two side walls of the channel 401. The first pull rope 9 connects the short swing rods 8 and the soft bag 11. Several water-absorbing weight-enhancing components 12 are disposed at both ends of the circular roller 5. In this invention, the water tank 10 is disposed on the ground, and the film 6 is wound up on the circular roller 5 in its original state, with one end connected to the long swing rod 4 in an L-shape. One side of the short swing rod 8 abuts against the circular roller 5 with the film 6 wound around it. Since the bottom of the short swing rod 8 is provided with a soft bag 11 through the first pull rope 9, the force of the circular roller 5, the film 6, and the several water-absorbing weight-enhancing components 12 themselves cannot push the short swing rod 8 to swing, thus preventing the circular roller 5 from rolling to the left on the long swing rod 4. When it rains, the several water-absorbing weight-enhancing components 12 absorb water and become heavier, and the short swing rod 8 is pushed by the circular roller 5 more slowly. As the rainwater gradually increases in size, the short swing rod 8 slowly rotates within the channel 401, and the roller 5 slowly rolls downwards. When the short swing rod 8 swings to a certain angle, the roller 5 rolls rapidly directly on the long swing rod 4 until the film 6 is released. Rainwater flows along the film 6 through the water trough 501 into the drainage tank 3, and then through the water inlet pipe 2 into the water tank 10. After the rain stops, the lifting device drives the other end of the long swing rod 4 downwards, causing one end of the long swing rod 4 to rotate within the opening 301. The long swing rod 4 tilts in the opposite direction, and the roller 5 rolls to the right end of the long swing rod 4. Due to the soft bag 11... When in contact with the ground of the rooftop, the first pull rope 9 is not straight. The short swing rod 8 is only subject to its own weight. The rolling of the roller 5 to the right directly drives the short swing rod 8 to rotate in the opposite direction. The roller 5 rolls between the short swing rod 8 and the stop 7, realizing automatic winding of the film 6. The lifting device drives one end of the long swing rod 4 to move upward. The end of the long swing rod 4 inside the opening 301 rotates. When the long swing rod 4 moves upward until the entire long swing rod 4 is horizontal, the soft bag 11 has lifted off the ground and exerts a pulling force on the first pull rope 9, which in turn exerts a downward force on the short swing rod 8, causing the short... The swing arm 8 supports the roller 5 after the film 6 is wound up, preventing it from rolling to the left. Since the drainage tank 3 is relatively sealed and the film 6 is wound up when not in use, the rainwater flowing into the water tank 10 is clean. Furthermore, the film 6, when released, can shield the floor and protect part of it. The film 6 between the baffle 7 and one end of the long swing arm 4 is not retracted and is exposed to the outside for a long time, accumulating dust or other objects. When it rains, the rainwater is blocked by the baffle 7 and discharged from both sides of the baffle 7, preventing it from flowing into the drainage tank 3. Specifically, there can be multiple water tanks 10 and inlet pipes 2; the long swing arm 4 has protrusions on both sides, which are rotatably connected to the side walls of the opening 301; the short swing arm 8 has protrusions on both sides, which are rotatably connected to the side walls of the through groove 401; the soft bag 11 is a sandbag; when the valve is opened, the water in the water tank 10 flows out from the drain pipe 101.

[0016] As a preferred embodiment of the present invention, it may also have the following additional technical features: In this embodiment, the lifting device includes a second pull rope 13 and two vertical plates 14 and two round rods 15. Two round rods 15 are provided between the two vertical plates 14. One end of the second pull rope 13 is connected to one end of the long swing rod 4, and the other end passes around one of the round rods 15 and is detachably connected to the other round rod 15. One end of the second pull rope 13 is fixed to the round rod 15 to fix the long swing rod 4. When it is necessary to wind up the film 6, one end of the second pull rope 13 is released, and one end of the long swing rod 4 moves downward, causing the long swing rod 4 to tilt in the opposite direction. The round roller 5 winds up the film 6, pulls the second pull rope 13 to move one end of the long swing rod 4 upward, and then causes the long swing rod 4 to return to its original position. One end of the second pull rope 13 is fixed, thereby fixing the long swing rod 4.

[0017] In this embodiment, weight-reinforcing ear plates 141 are provided on both sides of the bottom of the vertical plate 14 to prevent the vertical plate 14 from tipping over.

[0018] In this embodiment, a drain pipe 201 is provided on one side of the water inlet pipe 2. When the drain tank 3 is full, the water will be discharged outward from the drain pipe 201.

[0019] In this embodiment, the roller 5 is provided with discs 502 on both sides. One side of the disc 502 is in contact with one side of the long swing rod 4. When the roller 5 rolls on the long swing rod 4, the disc 502 will always be in contact with one side of the long swing rod 4, so that the roller 5 keeps rolling in a straight line.

[0020] In this embodiment, two sealing devices are also included for sealing the two openings 301 on the drainage tank 3.

[0021] In this embodiment, the drainage tank 3 is provided with four placement slots 302; the sealing device includes two abutment plates 16 and two springs 17. One end of the abutment plate 16 is inclined and can slide within the placement slot 302. The spring 17 is disposed between the wall of the placement slot 302 and one side of the abutment plate 16. The inclined end of the abutment plate 16 is in contact with the long swing rod 4 to seal the opening 301 and prevent dust or other objects from entering the drainage tank 3 through the opening 301. When the long swing rod 4 is tilted in the opposite direction, the upper abutment plate 16 is pushed upward by the long swing rod 4, and the lower abutment plate 16 is pushed upward by the spring 17, so that the two abutment plates 16 are always in contact with the long swing rod 4, thereby keeping the opening 301 sealed.

Claims

1. A rainwater harvesting device for the rooftop of a green building, comprising at least one water tank and an inlet pipe, with an outlet pipe on one side of the water tank and a valve thereon, characterized in that, Also includes: The drain box is installed on the top floor wall, with a water inlet pipe at the bottom and two openings on one side. The support device includes two long swing rods with one end in an L-shape and a lifting device. The two sides of one end of the long swing rod are rotatably connected to the two side walls of the opening. The lifting device is used to drive the L-shaped end of the long swing rod to move up and down. The long swing rod is provided with a through groove. The collection assembly includes a roller, a film, a stopper, two short swing rods, a first pull rope, and a soft bag filled with material. The roller has a through-flow channel. The film is initially wound onto the roller, with one end resting on the wall of the channel and the other end connected to the L-shaped end of the long swing rod. The stopper is positioned on the film. The two sides of the short swing rods are rotatably connected to the side walls of the channel. One side of the short swing rod abuts against the roller with the film wound around it. The first pull rope connects the short swing rods and the soft bag. Because the soft bag is located at the bottom of the short swing rods via the first pull rope, the forces of the roller, the film, and several water-absorbing weight-adding components themselves cannot push the short swing rods to swing, thus preventing the roller from rolling to the left on the long swing rod. When it rains, the water-absorbing weight-adding components absorb water and become heavier, increasing the thrust on the short swing rods from the roller. The short swing rods rotate within the channel, and when the short swing rods swing... After reaching a certain angle, the roller rolls rapidly on the long swing arm until the film is released. Rainwater flows along the film through the water trough into the drainage tank, and then through the water inlet pipe into the water tank. When the rain stops, the lifting device drives the L-shaped end of the long swing arm to move downwards, causing the long swing arm to tilt in the opposite direction. The roller rolls to the right end of the long swing arm, and the soft bag contacts the ground on the top floor. The first pull rope is not straight, and the short swing arm is only subject to its own weight. The roller rolling to the right can directly drive the short swing arm to rotate in the opposite direction. The roller rolls between the short swing arm and the stop, realizing automatic film winding. The lifting device drives the L-shaped end of the long swing arm to move upwards. When the L-shaped end of the long swing arm moves upwards until the entire long swing arm is horizontal, the soft bag has lifted off the ground and applies tension to the first pull rope, which in turn applies downward force to the short swing arm, allowing the short swing arm to support the roller after the film is wound, preventing it from rolling to the left. Several water-absorbing and weight-increasing components are set at both ends of the circular roller.
