[0025] Embodiment

[0026] Please refer to Figures 1 to 3 As shown, this embodiment provides a roof rainwater catch basin 1 for communicating with a rainwater pipe 2. The rainwater pipe 2 is provided on the roof 3, and the rainwater pipe 2 is used to discharge the rainwater on the roof 3. The roof rainwater catch basin 1 includes a pressing plate 11 and a weir plate member 12. The pressing plate 11 is provided on the circumference of the rainwater pipe 2, the pressing plate 11 is connected to the roof 3, and a positioning bump 111 protrudes from the surface of the pressing plate 11. The weir plate member 12 is connected to the positioning bump 111, the weir plate member 12 encloses the circumference of the rainwater pipe 2, the weir plate member 12 is provided with a drainage hole 121, the drainage hole 121 communicates with the rainwater pipe 2, and the weir plate member 12 is used to block the rainwater on the roof 3 and make the rainwater flow into the rainwater pipe 2 from the drainage hole 121.

[0027] The roof rainwater catch basin 1 provided in this embodiment is connected to the roof 3 through the pressing plate 11. A positioning bump 111 protrudes from the surface of the pressing plate 11. The weir plate member 12 is fixed to the circumference of the rainwater pipe 2 by connecting with the positioning bump 111. The weir plate member 12 is provided with a drainage hole 121. In rainy weather with a large amount of rain such as heavy rain, the rainwater on the roof 3 is blocked by the weir plate member 12 so that the rainwater slowly flows into the rainwater pipe 2 to regulate the flow rate of the rainwater discharged by the rainwater pipe 2.

[0028] In this embodiment, four positioning bumps 111 are provided. The four positioning bumps 111 are evenly arranged in the circumferential direction of the rainwater pipe 2. The roof rainwater hopper 1 is connected to the positioning bumps 111 through the weir plate member 12 to improve the stability of the weir plate member 12, reduce the occurrence of the situation where the weir plate member 12 is washed away by rainwater when the rainwater volume is large, and stably regulate the flow rate of the rainwater discharged from the rainwater pipe 2.

[0029] The diameter size of the drainage holes 121 is set according to the set drainage volume. When the rainfall is large, the roof rainwater hopper 1 blocks a part of the rainwater to the periphery of the weir plate member 12, and the other part of the rainwater flows into the municipal rainwater system from the rainwater pipe 2 through the drainage holes 121, so that the flow rate of the rainwater in the rainwater pipe 2 does not exceed the drainage capacity of the municipal rainwater system, thereby reducing the occurrence of disasters such as waterlogging in the plot and urban waterlogging.

[0030] In a possible implementation manner, the drainage holes 121 are arranged at a position of the weir plate member 12 close to the roof 3.

[0031] In this embodiment, the drainage holes 121 are arranged at a position of the weir plate member 12 close to the roof 3 to reduce the rainwater staying on the roof 3. When the rainfall decreases, the drainage holes 121 timely drain the rainwater on the roof 3 into the rainwater pipe 2.

[0032] In a possible implementation manner, a plurality of drainage holes 121 are provided, and the plurality of drainage holes 121 are arranged at intervals.

[0033] In this embodiment, four drainage holes 121 are provided. The four drainage holes 121 have the same horizontal height, and the four drainage holes 121 are evenly distributed in the circumferential direction of the weir plate member 12, so that the weir plate member 12 is stressed evenly, and thus the weir plate member 12 stably regulates the flow rate of the rainwater discharged from the rainwater pipe 2.

[0034] In a possible implementation manner, the weir plate member 12 includes a connecting plate 122 and a first weir plate 124 that are integrally connected. The connecting plate 122 is arranged along the horizontal direction. The connecting plate 122 corresponds to the pressing plate 11. The connecting plate 122 is provided with through holes 123. The through holes 123 cooperate with the positioning bumps 111. The positioning bumps 111 are inserted into the through holes 123 so that the connecting plate 122 is connected to the pressing plate 11. The first weir plate 124 is arranged along the vertical direction, and the drainage holes 121 are arranged on the first weir plate 124.

[0035] In this embodiment, the weir plate member 12 is connected or separated from the pressing plate 11 along the vertical direction through the connecting plate 122, so as to facilitate the installation and disassembly of the roof rainwater hopper 1, and enable the roof rainwater hopper 1 to simply and economically retain the rainwater on the roof 3 and relieve the drainage of the municipal rainwater system.

[0036] In a possible implementation manner, the drainage holes 121 are arranged at a position of the first weir plate 124 close to the roof 3.

[0037] In this embodiment, the drain hole 121 is provided at a position of the first weir plate 124 close to the roof 3 to reduce the rainwater staying on the roof 3. When the rainfall decreases, the drain hole 121 timely drains the rainwater on the roof 3 into the rainwater pipe 2.

[0038] In a possible implementation manner, the weir plate member 12 further includes a second weir plate 125. The second weir plate 125 is provided on the peripheral surface of the first weir plate 124, and the second weir plate 125 is movably connected to the first weir plate 124 along the vertical direction.

[0039] In this embodiment, when the rainwater storage amount on the roof 3 exceeds the height of the first weir plate 124, the drain hole 121 is too late to drain the rainwater. The second weir plate 125 raises its height along the vertical direction, so that the roof rainwater bucket 1 increases the height of the weir plate member 12 through the second weir plate 125, thereby further increasing the rainwater storage amount on the roof 3.

[0040] In a possible implementation manner, the second weir plate 125 is provided with a long hole 126. The long hole 126 extends along the vertical direction, and the second weir plate 125 is connected to the first weir plate 124 through a bolt 127 passing through the long hole 126.

[0041] In this embodiment, the height of the second weir plate 125 is adjusted along the vertical direction through the long hole 126, so as to adjust the rainwater storage amount on the roof 3.

[0042] In a possible implementation manner, the roof rainwater bucket 1 further includes a rainwater diversion cover 13. The rainwater diversion cover 13 is provided inside the weir plate member 12, and the rainwater diversion cover 13 is communicated with the rainwater pipe 2.

[0043] In this embodiment, the roof rainwater bucket 1 is provided inside the weir plate member 12 through the rainwater diversion cover 13, so that large particulate matters in the rainwater on the roof 3 are blocked inside the weir plate member 12, avoiding the blockage of the rainwater pipe 2.

[0044] In summary, the roof rainwater bucket 1 provided in this embodiment has positioning protrusions, so that the weir plate member 12 is stably fixed to the pressing plate 11 along the horizontal direction, and the weir plate member 12 is detachably or installed on the pressing plate 11 along the vertical direction, thereby improving the convenience of use of the roof rainwater bucket 1. The roof rainwater bucket 1 retains the rainwater on the roof 3 through the first weir plate 124 of the weir plate member 12, and adjusts the water storage amount of the weir plate member 12 by adjusting the height of the second weir plate 125, thereby controlling the flow rate of the rainwater discharged from the rainwater pipe 2.

[0045] The above embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail with reference to the above preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
