Novel metal building roof free water falling device

Abstract

The invention discloses a novel metal building roof free water falling device. The novel metal building roof free water falling device comprises an eave arranged at the edge of a roof, wherein the eave is vertically arranged at the edge of the roof; a gutter is fixed to the eave; the lower wall of the gutter communicates with a rain dividing groove; the lower part of the rain dividing groove communicates with and is fixedly connected with a flow guiding net; a plurality of vertical rain guiding curtains are fixed to the lower end face of the flow guiding net; and a plurality of rainwater pipesfixedly communicate with the bottom of the eave in a penetrating mode. The novel metal building roof free water falling device has the advantages that during raining, rainwater can be gathered to theeave and flows out downwards through the rainwater pipes and the flow guiding net, and free water falling is achieved; the multiple rain guiding curtains are arranged, the rain guiding curtains formthe flow guiding effect on the rainwater, and thus free water falling is more attractive; and when the rainwater amount is large, a servo motor drives a gear to rotate, the gear is engaged with an inner toothed plate to drive the inner toothed plate to move, a connecting rod moves in the horizontal direction along with a square sleeve, and the stirring effect on accumulated water in the eave is achieved.

Description

technical field [0001] The invention relates to the technical field of building roofs, in particular to a novel metal building roof free fall device. Background technique [0002] The metal roof drainage of steel structure buildings usually uses metal outer gutters or inner gutters with metal color steel downpipes or PVC downpipes. When the annual precipitation is large or the rainfall intensity is high in a short period of time, it often occurs that the gutter is full of overflow due to poor drainage of the downpipe, and even the rainwater flows back into the room to cause water leakage, which makes the water collection function of the gutter invalid and affects the actual situation. It brings great inconvenience during production and use. [0003] Therefore, it is necessary to develop a kind of open water-falling device, which can also realize the organized drainage of the roof without changing the building gutter. In addition, in the prior art, the building gutter is ver...

Problems solved by technology

When the annual precipitation is large or the rainfall intensity is high in a short period of time, it often occurs that the gutter is full of overflow due to poor drainage of the downpipe, and even the rainwater flows back into the room to cause water leakage, which makes the water collection function of the gutter invalid and affects the actual situation. Great inconvenience during production and use

[0003] Therefore, it is necessary to develop a kind of open water-falling device, which can also realize the organized drainage of the roof without changing the building gutter. In addition, in the prior art, the building gutter is very easy to accumulate earth and dust. These earth, Long-term accumulation of dust can easily lead to poor drainage, which will cause rainwater to accumulate on the roof, further leading to adverse consequences such as water leakage
