[0024] Both the drainage port 5 and the connecting net plate 9 are in a circular ring structure, and an anti-detachment block 12 is provided at the bottom end of the drainage port 5. The anti-detachment block 12 can prevent the filter net plate 10 from detaching. Through the setting of the anti-detachment block 12, it can support the filter net plate 10 in the drainage port 5, so that the filter net plate 10 always makes telescopic movements in the drainage port 5.

[0025] The lifting mechanism includes a docking groove 13 arranged on the municipal road 1 and several groups of telescopic support cylinders 14 vertically arranged at the bottom end of the well cover main body 3. The telescopic support cylinders 14 are arranged outside the connecting rod 11.

The lifting ring 16 can drive the well cover main body 3 to move, and at the same time drive the telescopic support cylinder 14 to stretch, which can effectively increase the water inlet area and accelerate the drainage efficiency. By pulling the well cover main body 3 upward through the lifting ring 16, it will drive the telescopic support cylinder 14 to stretch at the same time, and the well cover main body 3 will form a spacing with the well cover main body 3 under the height adjustment of the telescopic support cylinder 14, effectively increasing the water inlet area and accelerating the drainage efficiency.

[0027] On the connection grid plate 9, sliding rods 17 are symmetrically arranged, and on the drainage well 2, chutes 18 corresponding to the sliding rods 17 are symmetrically arranged.

[0028] The connection grid plate 9 has an annular structure, and the outer wall of the connection grid plate 9 fits against the inner wall of the drainage well 2.

[0029] When this municipal anti-blockage drainage inspection well cover that takes into account the exclusion of surface rainwater is in use, rainwater is drained through multiple drainage openings 5. When the rainwater enters the drainage openings 5, the debris in the water flow will be filtered by the filter grid plate 10. The filtered rainwater then passes through the connection grid plate 9 directly into the drainage well 2; when the filter grid plate 10 needs to be cleaned, directly manually pull the extraction ring 7, so that the extraction ring 7 pulls the connection block 6, and the connection block 6 drives the support column 8 and the connection grid plate 9 to move upward at the same time. During the upward movement of the connection grid plate 9, the connecting rod 11 and the filter grid plate 10 will be pulled to move synchronously until the filter grid plate 10 is supported by the connecting rod 11 and the impurities in the drainage opening 5 are pushed to the top of the drainage opening 5, then the impurities on the filter grid plate 10 can be cleaned, so that the well cover body 3 maintains smooth drainage; when the rain is urgent and the road is waterlogged, directly manually pull the lifting ring 16, so that the lifting ring 16 drives the well cover body 3 to move upward. At the same time, when the well cover body 3 moves upward, it will drive the telescopic support cylinder 14 to stretch, achieving height adjustment, and the well cover body 3 will form a spacing with the well cover body 3 under the height adjustment of the telescopic support cylinder 14, effectively increasing the water inlet area and accelerating the drainage efficiency. And the rainwater entering the drainage well 2 through the spacing will be filtered again by the connection grid plate 9, avoiding the accumulation and blockage of debris in the drainage well 2 and ensuring the normal drainage of the drainage well 2.

[0030] For this municipal anti-blockage drainage inspection well cover that takes into account the exclusion of surface rainwater, by pulling the connection block 6 with the extraction ring 7, the connection block 6 drives the support column 8 and the connection grid plate 9 to move upward. During the upward movement of the connection grid plate 9, the connecting rod 11 and the filter grid plate 10 are driven to move synchronously, and the impurities in the drainage opening 2 are pushed to the top of the drainage opening 2. This not only facilitates blocking the debris in the water flow and ensures the smooth drainage of the well cover body 3, but also makes the cleaning of the debris very quick and convenient. By driving the well cover body 3 to move upward with the lifting ring 16, and at the same time driving the telescopic support cylinder 14 to stretch, a spacing is formed between the well cover body 3 under the height adjustment of the telescopic support cylinder 14 and the well cover body 3, effectively increasing the water inlet area and accelerating the drainage efficiency.

[0031] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
