Sloping roof building rainwater drainage device

Abstract

The invention discloses a sloping roof building rainwater drainage device. The device comprises a sloping roof. A drainage groove is formed in the bottom end of the sloping roof in a penetrating mode.A grating plate is movably mounted in the drainage groove. A siphon plate is fixedly mounted at the lower end of the grating plate through connecting rods and mounted at the upper end of a drainage pipe. A turbine is rotationally arranged in the drainage pipe. The upper end of the turbine is fixedly connected with a rotary shaft. The rotary shaft movably penetrates through the middle of the siphon plate through a bearing, and in addition, the top end of the rotary shaft movably penetrates through the grating plate. The top end of the rotary shaft is located outside the grating plate and transversely and fixedly connected with a scraping plate. A bristlebrush is arranged at the bottom end of the scraping plate and makes movable contact with the top surface of the grating plate. When a water inlet of the drainage pipe is blocked, only a worker dredging method is available in the prior art. Through the rainwater drainage device provided by the invention, the turbine can be driven to rotate under the effect of rainwater flow, accordingly, the scraping plate provided with the bristlebrush is made to rotate repeatedly on the top surface of the grating plate, and tree leaves are scrapedoff the surface of the drainage pipe.

Description

technical field [0001] The invention relates to the technical field of rainwater drainage for buildings, in particular to a rainwater drainage device for buildings with sloped roofs. Background technique [0002] In the field of roof drainage of buildings with sloped roofs, siphon drainage pipes are usually used to drain the roof. However, due to the low height of this kind of building, more debris such as leaves will accumulate on the roof. This debris will flow into the water inlet of the siphon drainage pipe with the rainwater. If it is not treated in time, the debris such as leaves will easily accumulate. At the water inlet of the drainpipe, the drainage is affected. For this reason, we propose a rainwater drainage device for buildings with sloped roofs to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a rainwater drainage device for buildings with sloped roofs, so as to solve the problems raised in the a...
