DETAILED DESCRIPTION

[0023] See Figure 1 、 Figure 2 and Figure 3 The utility model is an H-tube roof rainwater utilization system, comprising a side-drain rainwater bucket 1, a rainwater storage riser 2, a rainwater overflow riser 3, a control valve 4, a permeable pipe 5, a water intake valve 6 and a building 8. The water inlet of the side-drain rainwater bucket 1 is arranged at the water flow convergence point at the roof edge of the building 8. The rainwater storage riser 2 is arranged vertically. The number of rainwater storage risers 2 can be set according to needs. The more the number of rainwater storage risers 2 is, the more water can be stored. The upper end of the rainwater storage riser 2 is connected with the outlet of the side-drain rainwater bucket 1, and the lower end of the rainwater storage riser 2 is connected with the permeable pipe 5. A control valve 4 is arranged between the rainwater storage riser 2 and the permeable pipe 5. During the rainwater collection process, the control valve 4 is in a closed state. Because it rains, the water in the yard The plants have sufficient water. Only when the environment is dry, the control valve 4 is opened to allow the water in the rainwater storage riser 2 to flow out to replenish water for the plants. The permeable pipe 5 is buried below the ground. An overflow hole is provided on one side of the upper part of the rainwater storage riser 2. The overflow hole is connected to a rainwater overflow riser 3 for introducing rainwater into the ground. When a large amount of rainwater is stored in the rainwater storage riser 2, the overflowed rainwater is discharged from the rainwater overflow riser 3. The excess rainwater is introduced into places where water is needed or where water is stored, such as lawns or puddles, through the rainwater overflow riser 3. A water intake valve 6 is provided on one side of the lower part of the rainwater storage riser 2. By opening the water intake valve 6, the water in the rainwater storage riser 2 can flow out and can be used for daily life or drinking water for livestock.

[0024] like Figure 1-3 As shown, a water intake pipe is provided on one side of the lower part of the rainwater storage standpipe 2, and a water intake valve 6 is provided on the water intake pipe. By providing the water intake pipe, the water in the rainwater storage standpipe 2 can be transferred to other places, such as indoors or on the grass. Figure 2 As shown, a metal connecting pipe 7 is connected between the side drain rainwater bucket 1 and the rainwater storage standpipe 2, through which the side drain rainwater bucket 1 and the rainwater storage standpipe 2 can be moved relative to a certain position, which is convenient for installation. Figure 2As shown, a parapet 81 is provided at the top of the building 8, with a drainage hole at the bottom. The side drain gutter 1 is installed in the drainage hole. Waterproof glue 11 is provided at the edge of the drainage hole and the side drain gutter 1, sealing the gap between the drainage hole and the side drain gutter 1. The lower end of the rainwater overflow riser 3 is 3 mm away from the ground. This small distance prevents animals such as rats from climbing into the rainwater collection system through the rainwater overflow riser 3.

[0025] like Figure 4-6 As shown, the water-permeable pipe 5 is set below the ground, and a water-permeable hole 51 is set on the water-permeable pipe 5. The outside of the water-permeable pipe 5 is wrapped with a non-woven fabric layer 52. The non-woven fabric layer 52 can make water slowly diffuse to the surroundings. Figure 4-6 As shown, a gravel drainage layer 53 is provided outside the non-woven fabric layer 52. Figure 4-6 As shown, a plug 54 is provided at the end of the water permeable pipe 5. By providing the plug 54 at the end of the water permeable pipe 5, water can be prevented from flowing out quickly from the end of the water permeable pipe 5, so that water can flow out slowly from the water permeable hole 51.

[0026] Working process of this utility model:

[0027] During the operation of the H-tube roof rainwater utilization system of the present invention, during the rainwater collection process, the control valve 4 and the water intake valve 6 need to be closed, and rainwater is collected from the roof into the side drainage rainwater bucket 1, and enters the rainwater storage riser 2 through the side drainage rainwater bucket 1. When the rainwater storage riser 2 is full of water, excess rainwater overflows into the rainwater overflow riser 3, and flows into the ground through the rainwater overflow riser 3. When the environment is dry and plants need to be watered, the control valve 4 is opened to allow rainwater to enter the permeable pipe 5. Finally, the rainwater flows into the ground below the surface through the permeable pipe 5, and flows slowly, evenly and smoothly to the surrounding area through the non-woven fabric layer 52 and the gravel drainage layer 53. When water is needed for daily use, the rainwater can be utilized by opening the water intake valve 6, and can be used for cleaning objects or drinking after high-temperature heating.

[0028] The utility model discloses an H-tube roof rainwater utilization system. By vertically arranging the rainwater storage riser 2 on the side of the building 8, rainwater on the top of the building 8 is directly collected, which reduces rainwater pollution, has low construction cost, low construction difficulty, short construction period, and convenient rainwater utilization. At the same time, the number of rainwater storage risers 2 can be flexibly selected according to needs, and the system has strong adaptability.

[0029] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the scope of protection of the present invention.
