Problems solved by technology

Its shortcoming is that it needs to be equipped with the same number of centrifugal pendulums as the vane group, and a steel pipe sleeved on the vertical shaft that can rotate relative to each other, and the same number of return tension spring plates as the centrifugal pendulum is fixed on the pipe wall , centrifugal pendulum tension spring hanging lug plate, slideway plate and other components, not only the structure is complex, the accuracy of wind wheel speed regulation is relatively low, but also the centrifugal pendulum tension spring is external, which increases the failure rate and maintenance difficulty

Embodiment Construction

[0032] The specific implementation of the wind power generator of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] figure 1 , 2 Shown is the three sets of blade vertical shaft wind power generators of the present invention, its structure includes the wind rotor tower 4 installed with the wind rotor, and the wind turbine base 8 and the tower 10 which are connected with the tower 4 vertically in sequence from top to bottom and base 11. Three groups of blades are arranged at intervals along the horizontal circumference. Each set of blades includes main blades 1 and auxiliary blades 2, and the main and auxiliary blades are connected together through a linkage mechanism 3;

[0034] A speed regulating cable 16 is set between each blade group and the tower column, and a confluence joint 14 and a pulling device are arranged in the tower column. Wherein, the far-center end of each speed-regulating cable 16 is respectivel...

Abstract

The present invention relates to a vertical shaft type wind power generator. The wind wheel of the vertical shaft type wind power generator comprises at least two groups of blades. Each group of blades is composed of main blades and auxiliary blades which are equally installed vertically in parallel. The main blades and the auxiliary blades are connected through a link mechanism. Simultaneously the speed regulation bracing cables with number same with that of the blade groups are simultaneously installed. The distal end of each speed regulation bracing cable is respectively connected with the auxiliary blade of each group of blades. The proximal end of each speed regulation bracing cable is centrally connected at a converging joint in a column. The converging joint is connected with a loading spring mechanism or a counterweight lifting mechanism positioned in the column. The vertical shaft type wind power generator of the invention can realize the automatic regulation of rotating speed of wind wheel according to the wind power and has the advantages of high speed regulation precision and reliable safety.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a vertical shaft controllable double blade combined wind power generator. Background technique [0002] Wind turbines are divided into horizontal axis type and vertical axis type. One of the technical difficulties of the vertical shaft wind turbine is to ensure that the speed of the wind rotor does not exceed the safety range of the mechanical structure such as the tower when the wind is strong. For this reason, existing vertical shaft wind turbines such as Chinese patent No. ZL85105331.9 are equipped with main and auxiliary blade structures. Changing the angle and returning to the position, thereby adjusting the torque of the wind wheel, so that the speed of the wind wheel will not be too high when the wind is strong. Its shortcoming is that it needs to be equipped with the same number of centrifugal pendulums as the vane group, and a steel pipe sleeved on the vertical shaft that can ...
