[0002] A bridge refers to a building built for roads to cross natural or artificial obstacles. It is built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to prevent rainwater from accumulating too much water on the bridge surface, bridges usually have drainage outlets to quickly discharge rainwater. In order to prevent the drainage outlet from being blocked, a filter structure is usually installed above the bridge drainage outlet to filter impurities and ensure the smooth flow of the bridge drainage outlet.

[0003] The utility model with the existing authorization announcement number CN220318354U discloses a bridge drainage device, including a first tube body, a second tube body and a water treatment device; the first tube body extends vertically and the top of the first tube body is connected to the drain port on the bridge, the second tube body is connected to the bottom of the first tube body and extends horizontally, and the second tube body is provided with a water inlet and a drain port connected to the water inlet.

[0004] By adopting the above technical scheme, rainwater is purified by a water treatment device before being discharged, which can avoid the problem of pollution or environmental damage caused by directly discharging rainwater into the water source under the bridge. However, in the above technical scheme, the existing bridge drain outlet filter structure does not have a self-cleaning function when in use. When encountering heavy rain, the bridge drain outlet filter structure is very likely to be blocked due to excessive impurities, thereby affecting the drainage efficiency of the bridge drain outlet, causing large areas of water accumulation on the bridge, which greatly affects the use effect of the bridge drain outlet filter structure.

[0005] To this end, we proposed a bridge drain outlet filtering structure to solve the above problems. Utility Model Content

[0010] Preferably, a water inlet cover is clamped on the top end of the filter cartridge, and a plurality of water inlet grooves are provided on the upper surface of the water inlet cover.

[0011] Preferably, a stabilizing ring is fixedly connected to the inner wall of the filter cartridge, and the upper surface of the stabilizing ring is fixedly connected to the bottom surface of the conical filter cover.

[0012] Preferably, the inner wall of the drainage cylinder is fixedly connected to a limiting ring, the upper surface of the limiting ring is provided with leakage holes arranged at equal distances, the bottom surface of the filter frame is in contact with the upper surface of the limiting ring, and the inner wall of the limiting ring is fixedly connected to the outer surface of the filter cylinder.

By setting a cover plate with a connecting rod, when there are too many impurities in the filter frame, it can be pulled upwards for cleaning, which increases the convenience of cleaning impurities in the bridge drainage outlet filter mechanism;

[0018] 2. The power provided by the rotating motor can drive the internal gears of the gear pump to rotate, thereby generating a certain suction force.

[0027] A filter frame 5 is provided inside the drainage cylinder 2, and the inner wall of the filter frame 5 contacts the outer surface of the filter cylinder 3. A stabilizing ring 15 is fixedly connected to the inner wall of the filter cylinder 3, and the upper surface of the stabilizing ring 15 is fixedly connected to the bottom surface of the conical filter cover 4.
