Honeycomb board wind power generator wind wheel blade

Abstract

The invention discloses a honeycomb board wind power generator wind wheel blade, which comprises a casing and an inside support structure, wherein the casing is mainly formed by combining an upper half case and a lower half case, the inside support structure is arranged in the casing and is respectively connected with the support part of the upper half case and the lower half case, the upper half case is formed by bending a first honeycomb board, the lower half case is formed by bending a second honeycomb board, the inside support structure is a metal sectional material, and the metal sectional material is vertically connected with the inner side of the head part of the casing and the inner side of the tail part and is connected with the inner wall of the casing by support points with the limited number at each cross section inside the casing except the inner side of the head part and the inner side of the tail part. The honeycomb board wind power generator wind wheel blade has the beneficial effects that the weight of a wind power generator wind wheel blade is effectively reduced, the wind-electricity conversion efficiency of a wind power generator is improved, simultaneously, the process for making the wind power generator wind wheel blade by the honeycomb board is simplified, and the manufacture cost is reduced.

Description

technical field [0001] The invention relates to a wind turbine blade of a wind power generator, in particular to a wind turbine blade made of a honeycomb board. Background technique [0002] The known wind turbine blades are generally made of glass fiber mixed with resin. Due to the problems of heavy weight, high brittleness, and harmful gas release during production, the wind rotor blades made in this way have light specific gravity and have Wind rotor blades with good fatigue strength and mechanical properties have become an important issue in the innovation of wind turbines. Because of their light specific gravity, high strength-to-weight ratio, average force, strong pressure resistance, good shock resistance and no deformation, honeycomb panels are ideal for manufacturing wind turbines. It is an excellent material for wind turbine blades for power generation, but due to the structural characteristics of honeycomb panels, it is quite difficult to process and combine them ...

[0002] The known wind turbine blades are generally made of glass fiber mixed with resin. Due to the problems of heavy weight, high brittleness, and harmful gas release during production, the wind rotor blades made in this way have light specific gravity and have Wind rotor blades with good fatigue strength and mechanical properties have become an important issue in the innovation of wind turbines. Because of their light specific gravity, high strength-to-weight ratio, average force, strong pressure resistance, good shock resistance and no deformation, honeycomb panels are ideal for manufacturing wind turbines. It is an excellent material for wind turbine blades for power generation. However, due to the structural characteristics of honeycomb panels, it is quite difficult to process and combine them into the shape of wind turbine blades, making it impossible to promote the use of honeycomb panels to manufacture wind turbine blades.
