[0006] Adopt the structure design, set up filter screen can filter the sundries in rainwater, prevent the sundries from being accumulated in the drainage pipeline and causing blockage, and simultaneously, the push-pull assembly can drive the reciprocating motion of the scraper, pushes away the sundries accumulated at the filter screen, so that rainwater can be discharged from the square steel pipe smoothly.
[0007] Preferably, the push-pull assembly includes a stand column fixedly connected to the roof, a drive motor mounted on the stand column, an output end of the drive motor penetrating through the stand column and fixedly connected with one end of a rotating rod, the other end of the rotating rod rotatably connected with one end of a connecting rod, the other end of the connecting rod rotatably connected with the scraper.
[0008] Adopt the above scheme design, the drive motor drives the rotating rod to rotate, and the rotating rod drives the scraper to reciprocate through the connecting rod, so that the scraper can scrape off the sundries attached to the filter screen back and forth.
[0009] Preferably, a skirt is fixedly connected to the water inlet of the square steel pipe, and the skirt is fixed to the parapet by sealing glue.
[0010] The waterproof performance of the connection between the parapet wall and the square steel pipe is effectively increased by the sealing effect of the skirt and the sealing glue, and the water on the roof is effectively prevented from penetrating into the parapet wall, so that the quality of the parapet wall is reduced.
[0011] Preferably, the water outlet end of the square steel pipe is downward and connected with a drain pipe, a hoop is fixedly sleeved on the drain pipe, and one end of the hoop is fixed on the outer wall through a fixing rod.
[0012] The above structure is adopted, the drain pipe is arranged to conveniently convey rainwater to the ground, the drain pipe is fixed on the outer wall through the hoop and the fixing rod, and the drain pipe is prevented from being separated from the outer wall due to large water flow.
[0013] Compared with the prior art, the utility model has the beneficial effects that:
[0014] The structure filters sundries in the rainwater through the filter screen, prevents the sundries from being accumulated in the drain pipe to cause blockage, the push-pull assembly can drive the scraper to reciprocate, the sundries accumulated at the filter screen are pushed away, and the rainwater can be smoothly discharged from the square steel pipe. BRIEF DESCRIPTION OF DRAWINGS
