Abstract

The invention discloses a wind generating set blade mold and a carbon fiber heating system of the wind generating set blade mold. A housing of the wind generating set blade mold comprises a working surface housing and a pneutronic surface housing. The housing of the wind generating set blade mold is orderly provided with a gel coating, a first enhancement layer, a heating layer, a second enhancement layer and an insulating layer from a cavity surface to outside. The carbon fiber heating system comprises a heating controller, and a carbon fiber cloth between the first enhancement layer and the second enhancement layer of the housing of the wind generating set blade mold. A temperature sensor is embedded in the carbon fiber cloth. The heating controller receives temperature data acquired by the temperature sensor installed in the carbon fiber cloth and carries out real-time monitoring and heating control of a heating temperature and heating time of the carbon fiber cloth. The invention also discloses the wind generating set blade mold. The carbon fiber heating system guarantees mold heating uniformity and reliability and a mold working life, reduces mold weight and a mold cost, and is not limited by a use environment.

Description

technical field [0001] The invention relates to the technical field of mold heating, in particular to a carbon fiber heating system for a blade mold of a wind power generating set and the blade mold. Background technique [0002] Wind power generation is the main form of wind energy utilization. Nowadays, the demand for wind power generators is increasing day by day. The blade is one of the main components of the wind turbine, and its condition is directly related to the performance of the unit. The blades of wind turbines are formed by injection and curing of various composite materials in the mold cavity. Wherein, curing includes early pre-curing and post-forming curing. When the composite material is pre-cured in the early stage and cured in the later stage, it is necessary for the mold shell to maintain a certain temperature and maintain it for a sufficient time, so that the formed blade can have sufficient strength. This requires good heating control of the blade mou...
