Problems solved by technology

However, when the rainstorm comes, due to the increase of a large number of impermeable areas such as concrete buildings, asphalt pavements, and parking lots in urban communities, the urban surface water flow increases, and the peak flow increases, leading to more and more serious urban waterlogging problems.
The disadvantage of the existing rainwater bucket is that it cannot delay the outflow time of roof rainwater, and it cannot reduce the peak flow of rainwater, which causes urban waterlogging damage caused by heavy rain

Embodiment Construction

[0010] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0011] like figure 1 and figure 2 As shown, the present invention comprises a diversion cover 1 and a drain pipe 2 connected to the lower part of the diversion cover 1, the top opening of the drain pipe 2 is a drain outlet 3, and the drain pipe 2 is extended upwards by 5-10 cm, equal to the height of the roof. Or the water outlet hole 4 that can drain in an appropriate amount is offered on the drainpipe 2 pipe wall of slightly lower place.

[0012] Since the drainage pipe 2 is extended upwards by 5 to 10 cm, the drain outlet 3 is higher than the roof, and the drainage water level of the roof is increased, when a heavy rain strikes, the roof can store a certain amount of water, so the present invention can delay the time of roof rainwater outflow and reduce the The flood peak flow of urban surface rainwater reduces the harm of urban waterlogging. And becau...

Abstract

The invention relates to a rainwater bucket, comprising a flow guide cover (1) and a water discharging pipe (2) connected with the lower part of the flow guide cover (1), wherein an opening at the top of the water discharging pipe (2) is a water discharging opening (3). The rainwater bucket is characterized in that the water discharging pipe (2) is upwards lengthened for 5-10 cm and a water discharging hole (4) which can discharge suitable amount of water is arranged on the pipe wall of the water discharging pipe (2) which is equal to the height of a roof or is slightly lower than the roof. The rainwater bucket disclosed by the invention has the advantages that the rainwater outflow time of the roof can be delayed and the city water-logging damages caused by torrential rain can be reduced.

Description

technical field [0001] The invention relates to a roof drainage facility, in particular to a rain bucket. Background technique [0002] The existing rain bucket mainly includes a deflector and a drainpipe connected to the lower part of the deflector. The top opening of the drainpipe is a drain. All the water in the roof. However, when the rainstorm comes, due to the increase of a large number of impermeable areas such as concrete buildings, asphalt pavements, and parking lots in urban communities, the urban surface water flow increases and the peak flow increases, leading to more and more serious urban waterlogging problems. The disadvantage of the existing rainwater bucket is that it cannot delay the outflow time of roof rainwater, and also cannot reduce the peak flow of rainwater, thus causing urban waterlogging damage caused by heavy rain. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rain bucket that ca...
