Fabricated double-layer drainage gutter applied to metal roof

Abstract

The invention relates to the technical field of drainage gutters, in particular to an assembly type double-layer drainage gutter applied to a metal roof.The assembly type double-layer drainage gutter comprises an upper-layer drainage groove, the middle of the upper surface of the upper-layer drainage groove is fixedly connected with a plurality of flow guide plates distributed in an annular array, and the flow guide plates are arranged to be in an arc shape; the inner pipe is rotationally installed in the middle of the upper-layer drainage groove, the lower end of the inner side wall of the inner pipe is fixedly connected with a plurality of inclined plates distributed in an annular array, and the upper end of the inner pipe is fixedly connected with a flange; the flow guide cover is fixedly mounted in the middle of the inner cavity of the upper end cover; the device has the beneficial effects that the inclined plate is fixedly connected to the inner wall of the lower end of the inner pipe, so that water enters the inner cavity of the upper end cover and then falls down along the inner wall of the inner pipe under the guidance of the flow guide cover, and when the water impacts the inclined plate, the inclined plate is obliquely arranged, so that the inner pipe and the upper end cover are driven to rotate, and impurities attached to the surface of the upper end cover are reduced; and the possibility that the upper end cover is blocked is reduced.

Description

technical field [0001] The invention relates to the technical field of drainage gutters, in particular to an assembled double-layer drainage gutter applied to metal roofs. Background technique [0002] With the development of metal roofing, the pros and cons of its drainage gutter structure will directly affect the overall waterproof performance. The commonly used drainage gutter is made of single-layer stainless steel bending. [0003] In the prior art, when the drainage gutter is connected with the drainage pipe, a floor drain is usually provided. [0004] However, at present, the existing floor drain is easily blocked by impurities in the water during use, thereby affecting the filtering effect of the floor drain. To this end, the present invention proposes a prefabricated double-layer drainage gutter applied to a metal roof to solve the above problems. SUMMARY OF THE INVENTION [0005] The purpose of the present invention is to provide a prefabricated double-layer dr...
