[0002] The municipal road drainage structure refers to a combination of a series of facilities and systems constructed to drain rainwater, sewage, etc. from the road surface and surrounding areas of the municipal road. Its main function is to collect, transport and discharge rainwater and sewage in a timely and effective manner, prevent road waterlogging, and ensure the normal use of the road, traffic safety and the sanitation of the surrounding environment.

[0003] For example, the Chinese patent with the publication number CN220953805U discloses a municipal road drainage structure, which includes a drainage seat. A drainage plate is installed on the top of the drainage seat, and a plurality of drainage grooves are opened on the top of the drainage plate. A dredging mechanism is arranged inside the drainage seat. The dredging mechanism includes: a movable seat movably connected to the bottom of the drainage plate, a dredging seat inserted into the top of the movable seat and matching the size of the drainage groove; a moving component installed at the bottom of the movable seat and driving the movable seat to slide at the bottom of the drainage plate; a reciprocating component installed inside the movable seat and driving the dredging seat to reciprocate up and down at the bottom of the drainage plate. By rotating the lead screw to drive the movable seat to move, the movable seat and the dredging seat move at the bottom of the drainage plate. Cooperating with the rotation of the cam to drive the dredging seat to move in the drainage groove, so that the movable seat and the dredging seat can move to each drainage groove in turn to dredge the drainage groove, prevent a large amount of impurities from accumulating and blocking the drainage groove, and ensure that the drainage structure can work normally for a long time.

[0004] The above patent has the following problems:

[0005] There are some disadvantages when using the above patent. For example, the above device can only ensure that impurities such as rotten grass, broken leaves and small stones on the road will not block the drainage groove, and cannot effectively collect and store impurities such as rotten grass, broken leaves and small stones on the road. And the device does not set up an effective filtering system, which will cause impurities such as rotten grass, broken leaves and small stones to enter the inside of the sewer, further causing blockage inside the sewer, greatly increasing the difficulty of workers dredging the sewer. In view of this, we propose a municipal road drainage structure. Content of the Utility Model

[0052] A driving assembly, which is located inside the outer shell 1 and is used to drive the scraping blade 5 to rotate.

[0053] Among them, when there is water accumulation on the road, impurities such as rotten grass, broken leaves and small stones in the water accumulation flow into the outer shell 1 through several drainage grooves 3 on the manhole cover 2. At the same time, impurities such as rotten grass, broken leaves and small stones will remain on the filter screen 7 under the filtration of the filter screen 7. The accumulated water will enter the filter pipe 14 through the filtration of the filter screen 7. At the same time, the driving component drives the scraping blade 5 to rotate on the filter screen 7, and the rotten grass, broken leaves and small stones and other impurities located on the filter screen 7 can be scraped out by the rotating scraping blade 5 and pushed into the storage groove, so that the rotten grass, broken leaves and small stones and other impurities can be collected and stored in the storage groove.
