Description
Technical Field
The invention relates to a scheme for filtering and collecting garbage in a roof drainage gutter, in particular to a roof siphon drainage and filter screen collection system.
Background
In recent years, with the development of science and technology, various buildings have appeared. The buildings with large span and large area are more and more, and the pipe diameter of a rainwater pipeline is increased due to the large area of the roof, the number of the stand pipes is increased, and the space use and the decorative attractiveness of the buildings are affected. Therefore, the conventional gravity rainwater drainage system is not suitable for drainage of large-volume buildings (Zhaoyiyang. Shallow roof rainwater siphon drainage system design [ J ]. Scientific wind, 2011 (23): 158-159.). With the introduction and the use of siphon drainage systems in the eighties and nineties of the last century, a new way for roof drainage is provided (royal red gorgeous, shallow talk about roof rainwater drainage system design [ J ]. Low carbon world, 2016 (05): 28-29.). For large-scale buildings, a siphon drainage mode with better drainage efficiency is also generally adopted so as to meet the drainage requirements of large-span and large-area buildings. The biggest difference of the siphon roof rainwater drainage system is that a rainwater hopper with good rectification function is adopted. The rain bucket can prevent air from mixing in a submerged state. During the drainage process, the pipeline is in a full pressure flow state, so that a siphon effect is formed (Wangwang red siphon rainwater drainage system is applied to roof drainage engineering [ C ]//.2012, 2 month building science and technology and management academy proceedings of 2012, 2012. However, the roof has the problem of dust and garbage accumulation for a long time, and when raining, the accumulated dust and garbage are easily accumulated at the siphon rainwater outlet under the scouring action of rainwater flow to block the rainwater outlet, so that the normal drainage function of the siphon rainwater hopper is influenced.
In view of the above, a roof siphon drainage and screen collection system needs to be developed by those skilled in the art.
