AI Technical Summary
Technical Problem
In existing technologies, the manhole cover is heavy, making it inconvenient for workers to move on the narrow base platform, resulting in high labor intensity.
Method used
A pivot is set on the root platform, and the manhole cover is fitted onto the pivot through the pivot hole. It can move along the pivot axis and rotate around the pivot. It is fixed with fasteners, and the cover is moved by the annular airbag. The cover can be opened and closed conveniently by the operation of the sealing component and rollers.
Benefits of technology
It reduces the labor intensity of staff, improves the convenience and efficiency of operation, ensures the sealing effect of the manhole, and facilitates inspection and maintenance.

Abstract
The application provides an assembly structure of a root platform and a manhole cover plate of a wind power blade, and relates to the technical field of wind power blade production. The assembly structure comprises: a root platform, which is provided with a manhole; a rotating shaft, which is arranged on the root platform; a manhole cover plate, which is sleeved on the rotating shaft through an axial hole and can move along the axial direction of the rotating shaft and rotate around the rotating shaft to cover or expose the manhole; a plurality of fasteners, which are fixed on the root platform and can fix the manhole cover plate and the root platform; an annular air bag, which is arranged on one side of the manhole cover plate facing the root platform, can move the manhole cover plate along the axial direction of the rotating shaft by inflating or deflating the air bag; and a sealing assembly, which is arranged on one side of the manhole cover plate facing the root platform and is used for sealing the gap between the manhole cover plate and the manhole when the manhole cover plate covers the manhole. The assembly structure solves the problem of high labor intensity of workers in the prior art due to the inconvenience of workers in moving the manhole cover plate because the manhole cover plate is heavy.
