Problems solved by technology

[0013] If the diameter of the wind rotor can be increased by 20%, the power can reach more than 10 megawatts; the cost of power generation can be further increased, and the existing structure and material strength can no longer support it, so it is necessary to find a new structure.

Embodiment Construction

[0038] Below in conjunction with accompanying drawing, the present invention will be further described with regard to preferred embodiment:

[0039] Such as figure 1 Shown:

[0040] The wind power rotor with T-shaped aileron combined with free ring reinforcement is mainly composed of: hub (1), blade (5) with free ring (4), and T-shaped aileron; in the T-shaped aileron beam part (2) T-shaped aileron rope terminal (9) and free ring rope terminal (8) are installed on the free ring, and the rope (3) is connected between the terminal posts; the free ring (4) can be fixed on the blade (5) The vertical column part (6) of the T-shaped aileron and the blades are all installed on the hub, and they are all in the plane of the wind wheel, and alternately form a radial attitude; the joint part (7) of the T-shaped aileron / blade is a rigid combined.

[0041] The T-shaped aileron, its T-shaped aileron vertical column part (6) and the T-shaped aileron beam part (2), are made of a wing struc...

Abstract

The invention belongs to the field of machines, and relates to a wind power wind wheel with T-shaped ailerons and free rings combined for reinforcement. The T-shaped ailerons fixed to a hub and the free rings which are mounted on blades and can freely rotate provide rope binding posts as rope fastening points. Ropes are guided to the adjacent T-shaped aileron binding posts on the two sides through the binding posts on the free rings and are locked, and a reinforcement rope network is formed by the totally 12 ropes. A vertical column part of each T-shaped aileron can have an aileron structure, a cross beam portion of each T-shaped aileron can have an aileron structure, or a certain nonzero angle can be clamped between the direction of the cross beam portion of each T-shaped aileron and the normal of the wind wheel to form a different-face line. Therefore, certain windward torque can be generated by the T-shaped ailerons, the wind wheel is driven to operate through the windward torque and the windward torque of the blades jointly, and the wind collection efficiency is improved.

Description

[0001] [technical field] [0002] The invention belongs to the field of machinery, specifically an auxiliary mechanical device for increasing the strength of a wind wheel and the efficiency of wind collection. [0003] [Background technique] [0004] The wind turbine is composed of a hub and blades; for large-scale wind generators, there is also a pitch change device (a device that changes the angle of attack of the blades) in the hub. [0005] The device that changes the angle of attack of the blade: it is a device that enables the blade to rotate on the axis of the hub, and adjusts the angle between the blade and the incoming wind to obtain better lift and improve the utilization rate of wind energy. Usually includes: pitch motor, pitch control cabinet, backup battery (or hydraulic equipment, motor can be used without hydraulic pressure), pitch bearing and other ancillary equipment. [0006] Pitch variable wind turbine means that the entire blade rotates around the central a...
