Description

A roof siphon drainage and filter collection system

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 net collection system.

Background technique

In recent years, with the development of science and technology, various buildings have appeared. Among them, there are more and more buildings with large spans and large areas. Due to the large roof area, this leads to an increase in the diameter of rainwater pipes and risers, which affects the space use and beautiful decoration of buildings. Therefore, the traditional gravity rainwater drainage system is no longer suitable for the drainage of large-scale buildings (Zhao Leiyang. On the Design of Roof Rainwater Siphon Drainage System [J]. Science and Technology Wind, 2011(23): 158-159.). As the siphon drainage system was introduced into my country and put into use in the 1980s and 1990s, it provided a new way for roof drainage (Wang Hongyan. Talking about the design of roof rainwater drainage system [J]. Low Carbon World, 2016(05): 28-29.). For large-scale buildings, the siphon drainage method with better drainage efficiency is usually used to meet the drainage requirements of large-span and large-area buildings. The biggest difference of the siphon roof rainwater drainage system is the use of a rainwater bucket with good rectification function. The rain bucket prevents air from getting in when it is submerged. During the drainage process, the pipeline is in a full-filled pressure flow state, thus forming a siphon effect (Wang Wenhong. Application of siphon rainwater drainage system in roof drainage engineering [C]//. February 2012 Construction Technology and Management Academic Exchange Paper Collection. 2012:57-58.), to achieve rapid drainage effect. However, due to the accumulation of dust and garbage on the roof for a long time, whenever it rains, the accumulated dust and garbage will easily form accumulations at the siphon rainwater outlet under the washing effect of the rainwater flow, blocking the rainwater outlet. Affect the normal drainage function of the siphon rainwater bucket.

In view of this, those skilled in the art are to develop a kind of roof siphon drainage and screen collection system.

Contents of the invention

In order to overcome the deficiencies and defects of the existing roof siphon drainage system, the present invention provides a roof siphon drainage and filter collection system, which can complete the filtering operation of roof rainwater while the roof drainage system is working to ensure the integrity of the roof drainage system. Maximum drainage efficiency.

A roof siphon drainage and filter collection system provided by the present invention combines a siphon drainage device and a filter net collector; it is a device that can realize garbage filtering on the drainage roof in the siphon, and the metal roof panel of the siphon drainage device It consists of continuous grooves and convex grooves. The rainwater pipe is arranged inside the convex groove of the metal roof panel. One end of the rainwater pipe is connected to the siphon rainwater bucket, and the other end is connected to the automatic water valve. The automatic water valve is installed in the center of the roof. When it rains, The automatic water valve will fill the rainwater pipe with water to form a siphon effect to achieve the effect of drainage. The filter screen collector is arranged on both sides of the siphon rainwater bucket in the gutter to collect the garbage in the roof rainwater in an all-round way. It has the advantages of economical application, convenient installation and smooth drainage. The commonly used siphon drainage method, because there are a lot of dust and garbage on the roof, when it rains, this part of dust and garbage will flow to the vicinity of the siphon rainwater bucket under the washing action of the rainwater, and it may block the rainwater bucket at any time, affecting its normal operation. The drainage function prevents the siphon drainage rainwater bucket from maximizing its drainage advantages. Therefore, the present invention starts from the problems faced by the current common drainage methods, and conceives a filter net collector on the basis of the siphon drainage mode, which is composed of two rectangular parallelepiped filters and a rectangular filter net, and the rectangular parallelepiped filters are arranged on both sides. The rectangular filter screen is arranged in the middle, and forms a whole by connecting with the upper part of the rectangular parallelepiped filter. The screen collector is fixed on the upper part of the siphon rainwater bucket in the gutter through detachable screws. When in use, the cuboid filters on both sides collect the garbage in the gutter, while the rectangular filter in the middle collects the garbage on the upper part of the roof, so that the garbage flowing to the siphon rainwater bucket can be collected in all directions to avoid rainwater buckets It is blocked and affects the normal drainage function.
