Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bridge drainage holes, in particular to an anti-blocking structure for drainage holes of highway bridges. Background Art
[0002] In order to avoid water accumulation on both sides of highway bridges, drainage holes are usually opened on both sides of the bridge pavement, and drainage cylinders are embedded inside to facilitate water outflow.
[0003] When the road is draining, although there is a filtering structure on the top of the drain barrel, when the rain is too heavy, deposits will accumulate on the top of the drain barrel and cannot be cleaned in time when the water is flowing. At the same time, some smaller debris will enter the drain barrel and then into the drainage pipe, causing blockage. For this reason, we propose an anti-blocking structure for the drain holes of highway bridges to solve the problem of blockage. Utility Model Content
[0004] The utility model aims to provide a highway bridge drainage hole anti-blocking structure, which can timely clean up the deposits and prevent smaller debris from entering the pipeline, so as to solve the above-mentioned background technical problems.

[0006] Preferably, a connecting plate 2 is fixedly connected to the bottom of the inner cavity of the filter cover, and the connecting plate 2 is rotatably connected to a rotating rod through a sealing bearing seat. A brush plate 2 is fixedly connected to the top of the rotating rod surface, and the bottom of the brush plate 2 is tightly fitted with the bottom of the inner cavity of the filter cover.
[0007] Preferably, the bottom of the rotating rod passes through the filter cover and extends to the bottom of the filter cover.
[0008] Preferably, a sealing ring is sleeved on the top of the surface of the drain cylinder.
[0009] Preferably, there are multiple paddles, and the multiple paddles are evenly fixed on the surface of the rotating rod.
[0010] Preferably, the highest end of the paddle plate is lower than the bottom end surface of the connecting plate 1, and the lengths of the front and rear end surfaces of the paddle plate are smaller than the inner diameter of the filter plate.
[0011] The beneficial effects of the utility model are as follows: 1. The utility model can filter larger debris through the filter plate, and the filter cover can filter smaller debris. When the rainwater is too heavy, the water flows into the drain barrel, and the rainwater will push the paddle plate due to gravity. The paddle plate drives the rotating rod 1 to rotate through the sealed bearing seat, thereby driving the main bevel gear to rotate. The rotation of the main bevel gear drives the rotating rod 2 to rotate, and the rotating rod 2 drives the rotating rod 2 to rotate through the sealed bearing seat, thereby driving the brush plate 1 connected to the surface of the rotating rod 2 to rotate, thereby scraping the filtered matter on the top of the filter plate to avoid blockage at the water inlet. By setting the above structure, the purpose of timely cleaning the deposits can be achieved, and at the same time, smaller debris can be prevented from entering the pipeline, thereby avoiding blockage in the pipeline.
[0012] 2. The utility model is provided with a rotating rod surface connected to the brush plate 2, and when needed, the drain cylinder can be taken out, and then the brush plate 2 can be driven to rotate by rotating the rotating rod, so that the bottom of the inner cavity of the filter cover can be cleaned, and the filtered material can be poured out in time to avoid the long-term accumulation of filtered materials.
[0013] 3. The utility model can fill the inner wall of the bridge opening by arranging a sealing ring, so that the drain tube fits on the inner wall of the hole.
[0014] 4. The utility model sets the highest end of the paddle plate lower than the bottom end face of the connecting plate 1, and the length of the front and rear end faces of the paddle plate is smaller than the inner diameter of the filter plate, thereby avoiding contact between the connecting plate 1 and the filter plate and the paddle plate, thereby affecting the rotation of the paddle plate.
