[0002] Gutter refers to the concave part between the two hips of the roof of a building. Roof drainage is divided into organized drainage and unorganized drainage (free drainage). Organized drainage generally collects rainwater into the gutter and then discharges it through the rainwater pipe. The ditch that collects rainwater is called a gutter. Gutters are divided into internal gutters and external gutters. Internal gutters refer to the gutters inside the outer wall.

[0003] The drainage gutter is placed at a high place, and a built-in drainage bucket is used for drainage. The downpipe of the drainage bucket has a narrow diameter and is easily blocked by large foreign objects, which affects the drainage efficiency. Therefore, we designed a drainage gutter structure for the roof of a steel structure building. A self-cleaning rain grate is set on the drainage bucket, which can scrape the debris that blocks the rain grate to the side, thereby not affecting the drainage efficiency of the drainage gutter.

[0022] Hereinafter, embodiments of the steel structure building roof drainage gutter structure of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4 The utility model shows a steel structure building roof drainage gutter structure of an embodiment of the utility model, which includes a water collecting bucket 2 installed at the bottom of the inner cavity of the drainage gutter body 1, and both sides of the top of the water collecting bucket 2 are fixedly connected with mounting plates 16, and the mounting plates 16 are fixedly installed on the side walls of the drainage gutter body 1 by tapping. The bottom of the water collecting bucket 2 is connected with a drain pipe 3, and a rain grate 4 is placed in the inner cavity of the water collecting bucket 2. A rotatable rotating rod 5 is penetrated at the central axis of the top of the rain grate 4. The bottom of the rotating rod 5 extends to the inner cavity of the drain pipe 3 and is fixedly connected with a fan blade 6. A rotating disk 7 is sleeved on the surface of the rotating rod 5. The top of the surface of the rotating rod 5 is threadedly connected with a limiting nut 10, and the bottom of the limiting nut 10 is fitted to the top of the rotating disk 7. By setting the limiting nut 10, the rotating disk 7 can be limited to prevent the rotating disk 7 from detaching from the surface of the rotating rod 5, and a plurality of rotatable ball bearings are embedded in the middle annular array at the top of the rain grate 4 11, the ball 11 is in rolling contact with the turntable 7. Through the setting of the ball 11, the turntable 7 will rotate on the ball 11 during its rotation, which reduces the friction of the turntable 7 and improves the smoothness of the rotation of the turntable 7. The inner cavity of the turntable 7 is fixedly connected with the limit strip 14, and the surface of the rotating rod 5 is provided with a limit groove 15 for the limit strip 14 to be inserted. Through the coordinated use of the limit strip 14 and the limit groove 15, after the limit strip 14 on the turntable 7 is inserted into the inner cavity of the upper limit groove 15 of the rotating rod 5, the turntable 7 can be rotated synchronously during the rotation of the rotating rod 5. Both sides of the top of the turntable 7 are fixedly connected with the lifting rod 8, and a scraper 9 is arranged below the lifting rod 8, which is attached to the top of the rain grate 4. Three movable movable rods 12 are arranged on the top of the lifting rod 8, and the bottom of the movable rod 12 is fixedly connected to the scraper 9. The surface of the movable rod 12 is sleeved with a spring 13, and the two ends of the spring 13 are respectively welded to the scraper 9 and the lifting rod 8.

[0024] Working principle: when the utility model is used, after rainwater flows into the drainage gutter body 1, it will be concentrated in the water collecting bucket 2, and the rain grate 4 will play a role in blocking debris. After the water flows into the water collecting bucket 2 and the drain pipe 3, the water flow will impact the fan blades 6 in the drain pipe 3. The fan blades 6 are tilted, and the water flow will cause the fan blades 6 to rotate, and the fan blades 6 drive the rotating rod 5 and the turntable 7 to rotate, and the turntable 7 drives the lifting rod 8 to rotate, and the lifting rod 8 drives the scraper 9 through the movable rod 12 to scrape the debris on the rain grate 4. In the process of scraping the debris, the scraper 9 will make the movable rod 12 move upward and squeeze the spring 13. The resilience of the spring 13 makes the scraper 9 close to the top of the rain grate 4 and scrape the debris. The retractable movement of the scraper 9 avoids the scraper 9 from getting stuck. The debris is finally moved to the side of the water collecting bucket 2 by the scraper 9, which is convenient for centralized cleaning later.

[0025] To sum up: the drainage gutter structure on the roof of the steel structure building enters the inner cavity of the water collecting bucket 2 and the drain pipe 3 through the water flow through the rain grate 4. The water flow impacts the fan blades 6 to drive the rotating rod 5 to rotate, and then drives the turntable 7, the lifting rod 8 and the scraper 9 to rotate, so that the scraper 9 scrapes off the foreign matter blocked on the rain grate 4 and moves it to one side of the water collecting bucket 2, effectively avoiding foreign matter blocking the rain grate 4 and affecting the drainage efficiency, and thus achieving the purpose of setting a self-cleaning rain grate on the drainage bucket, which can scrape the debris blocking the rain grate to the side, and thus will not affect the drainage efficiency of the drainage gutter.
