[0002] The roof is the load-bearing and enclosing component on the top of the building. It is generally composed of three parts: roofing, insulation layer and load-bearing structure. When rainy days come, a large amount of rainwater will accumulate on the roof. In order to prevent moisture and water seepage in the house, the rainwater will need to be discharged, and a drainage device is needed for this.

[0003] A Chinese patent with a search publication number of CN216893193U discloses a novel assembled building roof drainage device, comprising a drainage pipe 1, a filter plate, a cleaning device 1 and a cleaning device 2, wherein the drainage pipe 1 is opened at both ends, a drainage pipe 2 and a drainage pipe 3 are arranged on the opening side of the drainage pipe 1, the filter plate is arranged in the drainage pipe 1, the cleaning device 1 and the cleaning device 2 are both arranged on the drainage pipe 1, and the cleaning device 1 is located above the cleaning device 2. The utility model relates to the technical field of roof drainage, and specifically provides a novel assembled building roof drainage device with a simple structure and capable of cleaning the drainage pipe. However, there are still some shortcomings in the above-mentioned cleaning device 1 and the cleaning device, although the cleaning device 1 and the cleaning device can scrape and clean leaves and impurities on the filter plate, since no discharge port is provided on the drainage pipe 1, they cannot be collected, so that the scraped leaves and other impurities still exist in the drainage pipe 1, thereby causing blockage. For this reason, we propose a building roof drainage device. Utility Model Content

At the same time, the spring 704 will be stretched. At this time, the filter 6 can be slid out from the inside of the two horizontal grooves to complete the disassembly, and the filter 6 is passed through the placement groove again so that the two sides of the filter 6 enter the inside of the two horizontal grooves.
