Description

Technical Field

[0001] The utility model relates to the technical field of municipal bridge drainage, in particular to an anti-blocking drainage device for a municipal bridge. Background Art

[0002] In the development of urban transportation, bridge drainage construction is a very important task, which affects the normal operation of the city's drainage system. If there is a problem with bridge drainage, serious water accumulation will occur on the ground, causing damage to the road surface and polluting the urban environment.

[0003] The existing patent application number is CN 202020895504.5, which discloses a municipal bridge drainage filter device. By cyclically vibrating the filter plate up and down, impurities on the top of the inclined filter plate are promptly shaken off and collected into the collection filter box. However, bridge drainage contains large debris such as branches and plastic, which cannot be effectively removed by a single vibration method. Moreover, over long periods of use, the accumulation of debris affects the filtration effect of the filter plate, making it prone to clogging.

[0004] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility Model Content

[0007] A municipal bridge anti-blocking drainage device comprises a drainage trough and a grille plate installed at the upper end of the drainage trough, wherein the bottom of the drainage trough is provided with an anti-blocking mechanism, and the bottom of the grille plate is connected to a diversion mechanism;

[0008] The anti-blocking mechanism includes a mounting shell, a drive motor, a drive shaft, a plurality of staggered plow blades, a guide pipe, a group of relative rotating shafts and a plurality of spiral blades. The mounting shell is installed on the right side of the drainage trough, the drive motor is horizontally installed on the top of the mounting shell, the drive shaft is installed on the rotating end of the drive motor, and the left end is movably inserted in the drainage trough, a plurality of staggered plow blades are evenly installed on the drive shaft, the guide pipe is inserted on the left side of the bottom of the drainage trough, a group of relative rotating shafts are movably inserted in the bottom of the drainage trough, and the left ends extend into the guide pipes respectively, and a plurality of spiral blades are evenly installed on a group of relative rotating shafts.

[0009] Furthermore, the diversion mechanism includes a rotating rod, an inclined rod, a group of fixed rods, a rotating frame and a conical air guide cover. The rotating rod is movably installed at the center of the bottom of the grille plate, the inclined rod is installed at the bottom of the rotating rod, a group of fixed rods are installed on both sides of the bottom of the grille plate, the rotating frame is movably installed between a group of fixed rods, and the upper end of the conical air guide cover is connected to the inclined rod.

[0010] Furthermore, the upper end of the conical air guide cover is movably mounted in the rotating frame via a set of rotating shafts.

[0011] Furthermore, a plurality of guide grooves are evenly formed on the outer surface of the conical guide cover.
