Embodiment Construction

[0033] Embodiments of the present invention are described with reference to the accompanying drawings.

[0034] 1) The blades of the wind power generating set are formed by half-piece infusion molding, mold clamping and bonding, and the adhesive is cured to form a rough blank of the blade;

[0035] 2) The flash of the leading edge 2, trailing edge 3 and root 1 of the blade rough blank is cut off and polished smooth;

[0036] 3), the front edge 2 and trailing edge 3 of the blade shell outer surface mold clamping area needs to be strengthened for strengthening treatment;

[0037] 4) After the front edge 2 and trailing edge 3 of the blade are reinforced, they are repaired to achieve a good aerodynamic shape, and the surface of the blade shell is polished to form a uniform rough surface;

[0038] 5) On the surface of the blade (one side or both sides), mark the area 5 where the solar cell film needs to be installed. In particular, it is recommended not to install solar cells wit...

Abstract

The invention relates to a megawatt-grade wind generating set blade capable of carrying out photovoltaic power generation and a manufacturing method. The blade is a megawatt-grade wind power blade and has the surface area more than 150 m<2>; a flexible solar cell thin film is adhered to the surface of the blade by an adhesive; the solar cell thin film is assembled by blocks, and the blocks of the solar cell thin film are not influenced mutually and can independently generate electricity; and each block of the solar cell thin film is connected with a lead, and the current generated by the solar cell is introduced to electric power storage equipment or power grid through the lead. The wind generating set blade can simultaneously or independently carry out wind power generation and solar power generation so as to realize complementation and improve the utilization rate of land; the production is simple and feasible, the paving region of the flexible solar cell is reasonable in design, and the solar cell and blade shell can be maintained and repaired regionally so as not to influence adjacent regions; and due to the use of the flexible solar cell thin film, the paint consumption is reduced, and the pollution caused by painting of a great deal of chemical paint is avoided.

Description

technical field [0001] The invention relates to a wind power generation technology, in particular to a blade of a megawatt-level wind power generation unit capable of photovoltaic power generation and a manufacturing method. Background technique [0002] Solar energy is the most important basic energy among various renewable energy sources. Biomass energy, wind energy, ocean energy, water energy, etc. all come from solar energy. Broadly speaking, solar energy includes the above-mentioned various renewable energy sources. The energy of solar energy is huge, it can be said that it is inexhaustible and inexhaustible. [0003] As a kind of renewable energy, solar energy refers to the direct conversion and utilization of solar energy. Converting solar radiation energy into thermal energy through conversion equipment belongs to solar thermal utilization technology, and then using thermal energy to generate electricity is called solar thermal power generation, which also belongs t...
