Heating layer and heating method of megawatt level wind-powered blade mold

Abstract

The invention discloses a heating layer of a megawatt-grade wind power blade mould and a heating method thereof. The heating layer is arranged between an internal structure layer and an external structure layer that are formed on the surface of the mother mould of the mould; the invention is characterized in that the heating layer comprises at least three sections of heat conducting layer; each section of heat conducting layer is plainly paved at the corresponding positions of the blade tip, the middle part of the blade and the blade root at equal distance in the form of parallel arrangement by a plurality of guide copper pipes that bend into S shape; two ports of the guide cooper pipe extend out of the surface of the external structure layer and is connected with a heating device arranged externally; the heating method comprises the following steps: hot water is led into the heating layer cyclically, so as to meet the circulation mode of water of hot curing of wind power blade products; the hot water flows on the surface of the mould continuously, cyclically and repeatedly, thus meeting the temperature requirement of wind power blade products when in curing. The arrangement of the heating layer improves the moulding quality of large blade products; the dead weight of the mould is reduced, the production cost is low, and the heating method is safe and stable and is easy for application.

Description

technical field [0001] The invention relates to a mold heating layer and a heating method, in particular to a heating layer and a heating method of a megawatt wind power blade mold that can meet product curing heating requirements. Background technique [0002] Blades are key components of wind turbines to efficiently capture wind energy. Under the condition of fixed generator power, how to improve the power generation efficiency to obtain greater wind energy has always been the goal pursued by wind power generation, and the improvement of wind capture capacity is closely related to the shape, length and area of ​​the blade. The blade size The size depends mainly on the material from which the blade is made. The lighter the blade material, the higher its strength and rigidity, the stronger the blade's ability to resist loads, the larger the blade can be made, and the stronger its wind-catching ability. Therefore, composite materials with light weight, high strength and goo...

Problems solved by technology

[0005] In order to solve the hidden dangers of mold heating in the prior art and the measurement and control of electric heating completely rely on equipment and programs. Once the equipment is damaged or the program is wrong, it will seriously affect the production. The purpose of the present invention is to provide a A mold heating layer that uses water circulation to meet the curing temperature requirements of wind power blade products, and also provides a heating method for the mold heating layer
