Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a building roof drainage structure. Background Art

[0002] The roof is an important part of the building's exterior shape. The form of the roof has an important influence on the building's shape. At the same time, the roof is also the load-bearing structure of the house. It needs to have sufficient strength and rigidity to ensure the structural safety of the house. In addition, the roof also needs to have a good drainage structure to prevent rainwater or snow water from gathering on the roof in rainy and snowy weather, causing water seepage into the house.

[0003] Nowadays, most roofs are inclined downward at a certain angle, so that rainwater or snow water on the roof can flow out through the entrance of the roof drainage pipe to avoid water gathering. However, in rainy and snowy weather, there are usually some leaves, dead branches and other debris on the roof. These debris gather in the rainwater and snow water. When passing through the drainage pipe, it is very easy to cause blockage to the entrance of the drainage pipe, thereby reducing the drainage effect of the drainage pipe for rainwater and snowwater, and further causing rainwater and snowwater to gather on the roof, resulting in water seepage in the house. Utility Model Content

[0015] The technical solution of the utility model has at least the following advantages and beneficial effects:

[0016] 1. In rainy and snowy weather, the rain and snow on the roof surface enters the drainage hole through the filter plate and is discharged through the drainage hole. In the process of drainage, the filter plate can block and filter the fallen leaves and other debris on the roof, so as to effectively avoid the blockage of the drainage pipe by the rain and snow water, and improve the drainage effect of the rain and snow water;

[0017] 2. When the rainfall is too heavy, the rainwater has already gathered on the roof. At this time, the filter plate is driven upward by the driving component to open the filter plate and allow the rainwater to pass directly through the drainage hole. Since the water volume is large and the water flow is turbulent, it is difficult for impurities such as leaves to gather in the drainage pipe. There is no need to worry about clogging the drainage pipe. At the same time, the rainwater gathered on the roof can be discharged as soon as possible to avoid excessive accumulation of rainwater, which will cause water seepage on the roof surface.

[0018] 3. At the end of the rainy and snowy day, after the drainage is completed, lift the filter plate upwards. During this process, use the scraper to scrape off the debris on the filter plate, so as to ensure that the filter plate still has a good filtering effect in the next rainy and snowy weather.

[0043] The implementation principle of a building roof drainage structure proposed in the embodiment of the utility model is:

[0044] In rainy and snowy weather, rainwater on the roof surface 1 enters the drainage hole 12 through the filter plate 13, and the rainwater on the roof is discharged through the drainage hole 12. In the process of drainage, the filter plate 13 can block and filter the debris such as fallen leaves on the roof, so as to effectively avoid the blockage of the drainage pipe caused by the rainwater and snow water, thereby improving the drainage effect of the rainwater and snow water; when the rainfall is too heavy, the rainwater has already gathered on the roof. At this time, the filter plate 13 is driven upward by the driving component 3 to open the filter plate 13, so that the rainwater directly passes through the drainage hole 12. Since the water volume is large and the water flow is relatively turbulent at this time, impurities such as leaves are difficult to gather in the drainage pipe, and there is no need to worry about clogging the drainage pipe. At the same time, the rainwater gathered on the roof can be discharged as soon as possible to avoid excessive accumulation of rainwater, which causes water seepage on the roof surface 1; at the end of the rainy and snowy day, after the drainage is completed, the filter plate 13 is lifted upward.
