Description

Technical Field

[0001] This application relates to a rainwater harvesting device for building rooftops. Background Technology

[0002] To prevent rainwater accumulation or uncontrolled overflow, rainwater diversion devices are typically installed on roofs and platforms. Some use pre-designed internal drainage channels, but this type of structure can easily affect the overall building structure and is inconvenient for maintenance. Therefore, external structures are now generally used. However, existing external structures have limited rainwater discharge capacity, and overflows can damage the building walls. Therefore, it is necessary to improve existing rainwater harvesting systems to maximize their rainwater collection and discharge capacity, while also allowing for easy integration into the existing building structure and minimizing its impact. Utility Model Content

[0003] To address the aforementioned problems, this application proposes a rainwater collection device for building rooftops, comprising an obliquely positioned guide channel that cooperates with an outlet channel on the building rooftop, an end receiving trough at one end of the guide channel, and a bottom outlet pipe at the bottom of the end receiving trough; the guide channel includes a guide plate, lateral protective plates on both sides of the guide plate, and a splash guard on the top of the outer side of the end of the lateral protective plate. This application uses the guide channel to filter and collect rainwater, then collects it through the end receiving trough, and finally outlets it through the bottom outlet pipe; even with a large allowance, the water is generally outleted away from the building rooftop from the guide plate, avoiding direct overflow onto the building surface and reducing the impact on the building surface during heavy rainfall.

[0004] Preferably, the end receiving groove includes an inner vertical plate arranged along the extension direction of the guide plate, an oblique limiting plate arranged on the other side of the inner vertical plate, an inner guide plate arranged on the side of the inner vertical plate facing the outlet channel, and an outer guide plate arranged on the side of the oblique limiting plate facing the outlet channel.

[0005] Preferably, a filter section is provided at the top of the end receiving groove; the filter section includes an inner support plate fixedly disposed on the inner vertical plate and an outer support plate disposed on the inclined limiting plate, and an inclined filter screen is disposed between the inner support plate and the outer support plate.

[0006] Preferably, the inclined filter screen is disposed at the bottom of the inner support plate and the outer support plate. By setting the inclined filter screen, this application can avoid the blockage of the end receiving groove or the bottom outlet pipe by debris. The bottom connection structure also allows the filter part itself to have a certain capacity, minimizing the possibility of overflow at this point.

[0007] Preferably, the inclined limiting plate is a trapezoidal baffle, which is gradually moved away from the inner vertical plate.

[0008] Preferably, the guide plate is an arc-shaped plate that protrudes upwards. This application uses a guide plate with an upward protrusion, which can prevent rainwater accumulation and also increase the speed of rainwater drainage, directing rainwater as far as possible out of the building through the guide plate, end collection groove, and bottom outlet pipe.

[0009] Preferably, a bottom support block is provided at the bottom of the guide plate.

[0010] Preferably, the bottom support block includes a vertical support plate fixedly connected to the wall, a bottom support plate abutting against the bottom of the guide groove at the top of the vertical support plate, and an auxiliary connecting plate at the bottom of the vertical support plate and on the other side of the bottom support plate.

[0011] Preferably, an inner reinforcing support rod is provided between the bottom support plate and the vertical support plate.

[0012] This application can bring the following beneficial effects: 1. This application uses a guide channel to filter and collect rainwater, then collects it through an end collection channel, and then discharges it through a bottom outlet pipe; even if the reserved area is large, it will generally be discharged from the guide plate away from the top of the building to avoid direct overflow on the building surface and reduce the impact on the building surface when the rainfall is heavy.

[0013] 2. This application uses a guide plate with an upward protrusion, which can prevent rainwater accumulation and improve the speed of rainwater discharge, allowing rainwater to be discharged outside the building in the order of guide plate - end collection groove - bottom discharge pipe as much as possible.

[0014] 3. This application uses a guide plate with an upward protrusion, which can prevent rainwater accumulation and improve the speed of rainwater discharge, allowing rainwater to be discharged outside the building in the order of guide plate - end collection groove - bottom discharge pipe as much as possible.

[0017] To clearly illustrate the technical features of this solution, the following detailed description, in conjunction with the accompanying drawings, will be provided.

[0018] In the first embodiment, such as Figure 1 As shown, a rainwater collection device for building roof includes an obliquely arranged guide groove 2 that cooperates with the outlet channel 1 of the building roof. An end receiving groove 3 is provided at the end of the guide groove 2, and a bottom outlet pipe 4 is provided at the bottom of the end receiving groove 3. The guide groove 2 includes a guide plate 5, and lateral protective plates 6 are provided on both sides of the guide plate 5. A splash guard 7 is provided on the top of the outer side of the end of the lateral protective plate 6.

[0019] In use, rainwater is discharged from the outlet channel 1 at the top of the building to the guide plate 5 of the guide channel 2, then from the guide plate 5 into the end collection channel 3, and then from the end collection channel 3 into the bottom outlet pipe 4; the bottom outlet pipe 4 is generally laid towards the building through a bend, and discharged outside the building through a vertical pipe laid from the outside of the building.

[0020] In the second embodiment, as Figure 1-2 As shown, a rainwater collection device for building roof includes an obliquely arranged guide groove 2 that cooperates with the outlet channel 1 of the building roof. An end receiving groove 3 is provided at the end of the guide groove 2, and a bottom outlet pipe 4 is provided at the bottom of the end receiving groove 3. The guide groove 2 includes a guide plate 5, and lateral protective plates 6 are provided on both sides of the guide plate 5. A splash guard 7 is provided on the top of the outer side of the end of the lateral protective plate 6.

[0021] The end receiving groove 3 includes an inner vertical plate 8 extending along the guide plate 5, an inclined limiting plate 9 on the opposite side of the inner vertical plate 8, an inner guide plate 5 on the side of the inner vertical plate 8 facing the outlet channel 1, and an outer guide plate 5 on the side of the inclined limiting plate 9 facing the outlet channel 1. A filter section 10 is provided at the top of the end receiving groove 3; the filter section 10 includes an inner support plate 11 fixedly mounted on the inner vertical plate 8 and an outer support plate 12 mounted on the inclined limiting plate 9, with an inclined filter screen 13 positioned between the inner support plate 11 and the outer support plate 12. The inclined filter screen 13 is located at the bottom of the inner support plate 11 and the outer support plate 12. The inclined limiting plate 9 is a trapezoidal baffle, which is progressively positioned away from the inner vertical plate 8.
