AI Technical Summary
The existing concrete cover plate has a smooth surface and no fixing mechanism, resulting in a weak fixing effect with the manhole. After long-term use, it is easy to misalign or be washed away by rainwater, which is not practical.
Anti-slip protrusions and limiting protrusions are set on the cover plate body and the well opening to increase friction. Rainwater is collected in the water collection pan through the fixing mechanism. The fixing effect is enhanced by the linkage of the squeezing block, sliding rod and abutment plate. At the same time, a drainage structure is set to quickly discharge rainwater.
The improved fixation between the cover plate and the manhole prevents misalignment, displacement, and being washed away by rainwater, thus enhancing the practicality of the device and ensuring effective drainage.
