Description

Technical Field

[0001] The utility model relates to the field of building facilities, in particular to a rainwater collection and discharge structure on a building roof. Background Art

[0002] The significance of collecting rainwater on the roof of a building is mainly to use the collected rainwater, which is more energy-saving and makes full use of water resources. The rainwater on the roof has a certain potential energy and can be used to flush toilets downstairs or water vegetable gardens. Therefore, its collection and discharge structure makes it have a wide range of uses. However, at this stage, the temperature on the roof is very high in summer. After the rainwater on the roof is collected in the rainy season, it cannot cool the roof better. The traditional cooling method is to plant vegetation on the roof, but this method can easily evaporate the moisture in the soil, so it is necessary for people to irrigate it for a long time. If you forget to water it, it will easily cause the vegetation to die, which is not only troublesome but also has the risk of vegetation loss. For this reason, we propose a rainwater collection and discharge structure for the roof of a building. Utility Model Content

[0021] The lower end of the liquid level control water pipe 8 is connected to the inside of the water storage chamber wall 2, and the upper end of the liquid level control water pipe 8 is ten centimeters higher than the top waterproof floor 3; a waterproof cofferdam 301 is fixedly installed at the edge of the upper surface of the top waterproof floor 3, and a guardrail 302 is fixedly installed on the upper surface of the waterproof cofferdam 301; the water-saving planting structure 4 includes a stainless steel support leg 401, a microporous stainless steel splicing plate 402, a gravel layer 403, a planting soil layer 404 and a stone slab 405, and a stainless steel support leg 401 is fixedly installed at the peripheral position of the lower surface of the microporous stainless steel splicing plate 402. 1. The upper surface of the microporous stainless steel splicing plate 402 is paved with a crushed stone layer 403, the upper surface of the crushed stone layer 403 is paved with a planting soil layer 404, the upper surface of the planting soil layer 404 is paved with a stone slab 405, the lower surface of the microporous stainless steel splicing plate 402 is three centimeters higher than the upper end of the liquid level control water pipe 8, the stone slab 405 and the stairs 7 are for people to walk and view, the function of the crushed stone layer 403 is to block the planting soil layer 404, reduce the planting soil layer 404 blocking the mesh on the microporous stainless steel splicing plate 402 or reduce its entry into the microporous stainless steel splicing plate In the space below the connecting plate 402; the water supply structure 5 includes a water pump 501, a drainage pipe 502, a high-pressure rubber tube 503, a float 504, a filter screen cylinder 505 and a counterweight pendant 506. The output end of the water pump 501 is fixedly connected to the drainage pipe 502, and the input end of the water pump 501 is fixedly connected to the high-pressure rubber tube 503. The other end of the high-pressure rubber tube 503 extends into the interior of the water storage chamber wall 2 and is fixedly connected to the filter screen cylinder 505. The surface of the high-pressure rubber tube 503 is fixedly sleeved with a float 504 near the position of the filter screen cylinder 505. The float 50 4 is evenly distributed with counterweight pendants 506 near the edge of the lower surface, wherein the float 504 is set to allow the filter screen cylinder 505 to always float near the liquid surface, reduce the suction of debris such as mud and stones, and avoid clogging. The counterweight pendant 506 is to prevent rollover and make the float 504 float more stably on the water surface; the other end of the drainage pipe 502 passes through the waterproof cofferdam 301 and is connected to the inner side of the waterproof cofferdam 301. A plurality of microporous stainless steel splicing plates 402 are provided and are laid on the upper surface of the top waterproof floor slab 3 through docking.

[0022] It should be noted that the utility model is a rainwater collection and discharge structure for a building roof. When in use, rainwater falls on the planting soil layer 404 during the rainy season, and then penetrates through the micropores of the gravel layer 403 and the microporous stainless steel splicing plate 402 to enter the top waterproof floor 3. When the water in the top waterproof floor 3 overflows the upper port of the liquid level control drain pipe 8, the water will be discharged into the water storage chamber wall 2 through the upper port of the liquid level control drain pipe 8 for storage. If the liquid level in the water storage chamber wall 2 rises to the connection between the discharge pipe 6 and the water storage chamber wall 2, the excess water will be discharged into the discharge pipe 6 for discharge. On sunny days, the temperature causes the water on the inside of the waterproof cofferdam 301 to evaporate, and the steam will enter the gravel layer 403 through the multiple micropores on the microporous stainless steel splicing plate 402, and pass through the gravel layer 40 3 enters into the planting soil layer 404, so that humid gas can be provided to the gravel layer 403 and the planting soil layer 404 to achieve the purpose of irrigation. In the dry season, if the water inside the waterproof cofferdam 301 is almost dry, the water pump 501 can be started to introduce the water inside the water storage chamber wall 2 into the drain pipe 502 through the filter screen cylinder 505 and the high-pressure rubber tube 503, and then the drain pipe 502 is discharged into the inside of the waterproof cofferdam 301. After a period of time, if the sound of falling water is heard inside the water storage chamber wall 2, it means that the overflowing water in the waterproof cofferdam 301 falls into the water storage chamber wall 2 from the liquid level control sewer pipe 8. At this time, the water pump 501 can be turned off to complete the watering, and the watering can be supplied for a long time at a time, which reduces the frequency of watering and saves manpower, and has a better cooling effect on the indoor in summer.
