Abstract
The utility model provides a wind turbine blade of a horizontal-axis wind turbine, and belongs to the technical field of horizontal-axis wind turbines. According to the structure of the wind turbine blade, the blade comprises an upper shell, a lower shell and a large beam, a D-type beam is adopted by the large beam, a reinforcing supporting beam perpendicular to a chord plane is arranged in the center of the inner cavity of the D-type beam, the top end and the bottom end of the reinforcing supporting beam are respectively and fixedly connected with the inner surface of the D-type beam, the upper surface of the D-type beam is spliced and fixed with the inner surface of the upper shell, the lower surface of the D-type beam is spliced and fixed with the inner surface of the lower shell, the front edge of the upper shell and the front edge of the lower shell are overlapped, spliced and fixed, and the joint of the rear edge of the upper shell and the joint of the rear edge of the lower shell are spliced and fixed. A C-type front edge arc plate is spliced and fixed to the inner surfaces of the front edges of the upper shell and the lower shell. According to the wind turbine blade of the horizontal-axis wind turbine, the longitudinal reinforcing supporting beam is additionally arranged in the center of the D-type beam in a composite mode, the advantage of small weight can be still maintained, rigidity and strength of the front edge of the blade are enhanced, safety of blade transportation can be guaranteed, and deformation in the blade transportation process is maintained.
Description
Technical field
The utility model relates to horizontal axis wind-driven generator technical field, specifically a kind of Horizontal shaft aero-generator wind wheel blade.
Background technique
General, Horizontal shaft aero-generator wind wheel blade girder adopts the patterns such as simple D type, O type, rectangle and C type mostly, and stressed-skin construction is thinner, only 2～3mm, the torque load that mainly keeps aerofoil profile and bear blade; Be characterized in lightweight, transport of blades is had relatively high expectations.Because blade inlet edge strength and stiffness are lower, in transportation process, part is easy to damage.This blade integral rigidity is lower simultaneously, and the distortion of running Leaf is larger, very easily causes trailing edge cracking, causes very large economic burden.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of Horizontal shaft aero-generator wind wheel blade is provided.
The technical solution of the utility model realizes in the following manner, this Horizontal shaft aero-generator wind wheel blade, its structure is that this blade comprises upper casing, lower casing and crossbeam, crossbeam adopts D type beam, D type beam inner chamber central authorities are provided with the reinforcement support beam of vertical string face, strengthening support beam top is fixedly connected with D type beam internal surface respectively with bottom, the upper surface of D type beam is adhesively fixed with upper casing internal surface respectively, the lower surface of D type beam is adhesively fixed with lower casing internal surface respectively, overlapping being adhesively fixed of leading edge of upper casing and lower casing, the trailing edge seam bonding of upper casing and lower casing is fixing.The leading edge internal surface of upper casing and lower casing is adhesively fixed with C type leading edge arc plate.
Strengthen support beam one end and extend to blade root place.
The beneficial effect that the utility model compared with prior art produced is:
This Horizontal shaft aero-generator wind wheel blade adopts the compound longitudinal reinforcement support beam that adds of D type beam central authorities, it still can keep lightweight feature, and add C type leading edge arc plate in the leading edge inside of blade most fragile, strengthen rigidity and the intensity of blade inlet edge, contribute to guarantee the Security of transport of blades, deformation while maintaining transport of blades, prevent blade front and rear edges cracking, and this Horizontal shaft aero-generator wind wheel leaf weight is light, blade rotary is brisk, light-duty blade, carrying is good and reliable.
This Horizontal shaft aero-generator wind wheel blade blade has the aerofoil profile of accepting efficiently wind energy, rational established angle, outside ratio of lift coefficient to drag coefficient, tip-speed ratio and the twist angle of blade of science, material and the advanced technique that also will have rational structure, high-quality, make blade have the ability of bearing reliably wind-force.
This Horizontal shaft aero-generator wind wheel blade adopts fibre reinforced composites manufacture, and it has endurance, structural stability, anticorrosive, resistant to elevated temperatures performance.
This Horizontal shaft aero-generator wind wheel blade can be according to loading characteristic design strength and the rigidity of fan blade; The easy moulding of aerofoil profile, and reach maximum pneumatic efficiency; Good anti-vibration, the natural frequency of vibration can designed, designed; Fatigue strength is higher; Corrosion resistance and weathering resistance are good; Keep in repair easy, be easy to repair.
This Horizontal shaft aero-generator wind wheel blade design is reasonable, simple in structure, safe and reliable, easy to use, be easy to safeguard, has good value for applications.
