Abstract

The invention relates to the field of wind power generator blade structures, in particular to a wind power blade manhole cover plate and a manufacturing method thereof. The cover plate comprises a cover plate body arranged on a blade root baffle. Bolt holes are formed in the cover plate body. The cover plate body is made of rubber. A steel wire gauze is arranged in the cover plate body. A steel sleeve matched with bolts and fixedly connected with the cover plate body is installed in the bolts in a sleeved manner. The steel sleeve protrudes out of the inner surface of the cover plate body. Twosealing rings are fixed to the inner surface of the cover plate body. The steel sleeve is arranged between the two sealing rings. A sealing steel plate corresponding to the steel sleeve is further arranged in the cover plate body. The cover plate can absorb loads and vibration transferred from the blade root through the blade root baffle, the bolts are protected, and the bolts are prevented from breaking.

Description

technical field [0001] The invention relates to the field of wind power generator blade structure, in particular to a wind power blade manhole cover plate and a preparation method thereof. Background technique [0002] During the operation of the fan, if the remaining items in the blades fall and hit the hub, it will cause damage to the hub and affect the normal operation of the fan. In order to avoid the above-mentioned problems, the existing wind turbine blades usually adopt a design in which a blade root baffle is installed at the position of the blade root to separate the blade cavity from the hub. When checking and repairing the blade, maintenance personnel need to enter the blade through the blade root baffle. In order to allow the maintenance personnel to enter the blade, a manhole is usually set at the center of the blade root baffle, and this manhole requires a manhole cover and blade Root baffle assembly, and then realize all the above functions. At the same time...
