[0025] The effect achieved by the entire embodiment 1 is that when the anti-water accumulation manhole cover is used on the municipal road, the mounting seat 1 needs to be installed on the top of the manhole first, and the manhole cover body 5 is inserted into the corresponding positioning hole 2 through the multiple positioning rods 4 arranged at the bottom edge thereof, so that the manhole cover body 5 is covered on the top of the mounting seat 1, and the manhole cover body 5 is limited. When it rains or there is water accumulation on the road surface, the water flow will flow into the multiple outer circle drainage holes 11 and the multiple inner circle drainage holes 12 respectively under the guidance of the outer annular groove 8 and the inner annular groove 9. When the water flow flows under the manhole cover body 5, the water flow flowing into the inner circle drainage holes 12 will directly The top of the conical second connection block 306 is impacted, and the water flowing into the outer ring drainage hole 11 will first impact the first connection block 301. Since the first connection block 301 is funnel-shaped, the water will flow from the edge of the first connection block 301 to the hole in the center and impact the second connection block 306.

The water flowing into the inner ring drainage holes 12 will directly impact the top of the conical second connecting block 306, and the water flowing into the outer ring drainage holes 11 will first impact the first connecting block 301. The impact will cause the water flow to flow down from the edge of the funnel-shaped first connecting block 301 to the hole in the center, and impact the second connecting block 306. When the impact force of rainwater or accumulated water is large enough, the second connecting block 306 will move downward accordingly, so that when the second connecting block 306 moves downward, the first connecting block 301 will move downward accordingly through multiple fixed blocks 308 and fixed rods 309.

When the rain stops or the impact force of the inflowing water flow is small and not enough to squeeze the multiple springs 304, the multiple springs 304 will squeeze the multiple first limit blocks 305 and the first connecting block 301 respectively under the action of their own elastic reset, and the first connecting block 301 will drive multiple The dredging rod 302 moves to the corresponding outer circle drainage hole 11. A raised block is provided on the outer surface of the dredging rod 302 near the top side, so that the dredging rod 302 can dredge the sludge that is adhered or blocked in the outer circle drainage hole 11 when moving up and down in the outer circle drainage hole 11, and prevent multiple outer circle drainage holes 11 and multiple inner circle drainage holes 12 from being blocked, thereby ensuring the unobstructed flow of the outer circle drainage holes 11, and quickly draining the water accumulated on the top of the manhole cover body 5, thereby improving the drainage effect of the anti-water accumulation manhole cover on the official road.
