Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a drainage device used in roof waterproofing projects. Background Art

[0002] When waterproofing the roof, rainwater flowing down from the roof can be collected and diverted through a drainage device. According to the patent authorization announcement number: CN221219400U, a drainage device for roof waterproofing projects is proposed. When the utility model is in use, rainwater will flow in from the strip holes of the connecting cover, flow into the drain pipe through the filter holes, and finally flow out from the lower end of the drain pipe. The water in the gutter in the sleeve can be drained through the "siphon" effect. When the rainwater is drained, larger debris has been blocked by the connecting cover, and then the rainwater falls through several filter holes on the fixed plate. At this time, smaller debris is also blocked and gradually gathers at the edge of the fixed plate, which will not cause a major impact on the passage of rainwater.

[0003] However, in conventional drainage devices, debris may enter the drainage box during use, which can easily clog the filter cover and prevent the device from draining properly. Furthermore, when cleaning the drainage device, the filter cover is installed with bolts, which are prone to rust, making it difficult to remove the drain cover. Therefore, there is a need to improve the conventional technology. Utility Model Content

When filtering rainwater, the driving frame can be driven to rotate by a waterproof motor. During the rotation of the driving frame, the outer surface of the filter cover can be cleaned by the brush, thereby effectively avoiding clogging of the filter cover.

[0013] 2. The utility model adds a mounting frame, a movable frame, a spherical column and other structures inside the filter cover.
