In addition, the lower side of the inspection well cover base is provided with an anti-falling net to strengthen the protection of pedestrians.

The working principle is as follows: through the utility model discloses a lift inspection shaft lid, the inflation body of centre passes through to absorb water when the rainy day, because the inflation body of more messenger of the first half inflation of expansion coefficient problem is crooked to lift the one end of inspection shaft lid body, thereby make inspection shaft lid both sides lift up the displacement that a great delivery port improved the inspection shaft lid, the angle after the prediction was raised is 25. Due to the expansion limit, the product does not lift indefinitely. When the vehicle runs, the lifted inspection well cover can be flattened due to the heavy weight of the vehicle, water in the expansion body can be separated out due to the weight in the flattening process, so that normal vehicle passing on a road is not affected, and after the vehicle runs, the expansion body absorbs water again to lift the cover body again. The product can be recovered to the non-working state through natural evaporation under the condition of raining and sunny days.

The utility model discloses a direction that its lid of lift inspection shaft lid was fixed so can control to raise by the base, thereby the lid direction does not obstruct the vehicle with the road is parallel to go normally, also can reduce the phenomenon of stumbling the pedestrian under the open mode with the direction parallel of pedestrian's walking simultaneously, has also solved the possibility that need be removed the inspection shaft lid and increase the drainage and can cause huge potential safety hazard to the pedestrian. The cover body part is provided with a reflective material (such as red), so that the cover body part can also achieve a good warning effect on pedestrians and vehicles, and can also achieve a guiding effect on a route through the reflective inspection well cover during driving at night.

The utility model discloses can the split be two inspection shaft lid bodies, an inflation connecting piece, an inspection shaft lid base, one prevent the net that falls, these parts all can the split change, and this is more economical than original inspection shaft lid change to reduce the spending to this aspect of product. The product has the function of meeting the existing sustainable development principle through the expansion operation of the expansion body without using other energy sources.

Through the utility model discloses a lift inspection shaft lid can the effectual drainage ability that improves the city, has solved the potential safety hazard that some areas used improper drainage mode to bring simultaneously, does not influence the normal driving of vehicle when improving drainage ability simultaneously and has also brought very big facility to the urban traffic of rainy day.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
