Problems solved by technology

In the prior art, the wind energy utilization rate of the vertical-axis lift fan can be as high as 42% during normal operation, but it has the following defects: small starting torque, complex structure, high cost, low speed of the wind rotor, poor stability, vibration, etc. Large and resonant, and a small range of wind speeds for effective use
However, the stability and balance of the vertical flexible wind rotor of the vertical axis flexible wind rotor also need to be further improved, and the resonance that is easy to occur in a wide speed range under the action of various wind forces and wind directions is relatively severe, which also It needs to be further solved, and the flexible suspension cable is easy to knot and break, which makes it have a low service life and is difficult to use in strong winds

Embodiment 1

[0043] A wing-swinging-blade vertical-axis wind power generating set of the present invention, such as Figure 1 to Figure 3 As shown, it includes a generator 11 installed on the tower column 12 and a wind wheel installed on the vertical axis of the generator 11. The wind wheel includes a rotating bracket 7 and a plurality of sets of fan blade units. The rotating bracket 7 and the generator 11 The vertical axis is fixedly assembled and connected. Each group of fan blades 1 unit includes a support rod 2, a hinge mechanism and a fan blade 1. One end of the support rod 2 is provided with a hinged seat 9, which is hinged with the rotating bracket 7 through the first pin shaft 8. , the fan blade 1 is hinged to the other end of the strut 2 through a hinge mechanism, and when the wind wheel is stationary, all the struts 2 are at the same level. Wherein, the axial direction of the first pin shaft 8 is perpendicular to the length direction of the corresponding strut 2 , so that the bla...

Embodiment 2

[0065] A wing-swinging-blade vertical-axis wind power generating unit of the present invention is basically the same as Embodiment 2. In this embodiment, the five hinges are fixedly arranged on the groove-shaped hinges of the wind blade 1, and the two side walls A through hole for passing through the second pin shaft 3 is opened symmetrically, and the axis direction of the through hole is perpendicular to the length direction of the fan blade 1 . At the same time, one end of the support rod 2 hinged with the hinge 5 is provided with a hinge joint, and the hinge joint is provided with a through hole for passing through the second pin shaft 3, and the axis direction of the through hole is perpendicular to the length direction of the fan blade 1. And the hinge is located in the groove of the hinge 5, and the second pin 3 passes through the through hole of the hinge 5 and the through hole of the hinge. The second end of the hinge 5 is hinged to the strut 2 through the second pin 3...

Embodiment 3

[0068] A wing-swinging-blade vertical axis wind power generating unit of the present invention is basically the same as Embodiment 2. In this embodiment, the number of blade units is set to two groups, and the included angle between the two groups of blade units is 180°. °, the wind wheel of this structure has few materials, light weight and low cost.

[0069] The main technical solutions of this embodiment are basically the same as those of Embodiment 1 or Embodiment 2, and the features not explained in this embodiment are explained in Embodiment 1 or Embodiment 2, and will not be repeated here.

Abstract

A wing-swinging-blade vertical-axis wind power generator set, one end of the strut is provided with a hinged seat, the hinged seat and the rotating support are hinged through a first pin shaft, and the axial direction of the first pin shaft is perpendicular to the length direction of the strut, The fan blade is hinged to the other end of the pole through a hinge mechanism; a buffer pad is arranged between the rotating bracket and the pole. Compared with the prior art, the pole and the rotating bracket are hinged through the hinge seat and the first pin shaft, and the gyro effect is used to improve the stability of the vertical axis wind turbine. At the same time, there is an elastic The buffer pad made of high-quality material makes all the support rods on the same level, effectively ensuring the stability of the whole machine and the stable output power of the generator. And because the blades and the poles are hinged by a hinge mechanism, the windward area of ​​the wind wheel can be adjusted according to the wind force, and it can also generate electricity normally in strong winds. It has good resistance to strong winds, and there is no tail rudder. Low.

Description

technical field [0001] The invention relates to the technical field of vertical-axis wind power generators, in particular to a wing-swinging-blade vertical-axis wind power generator capable of stable rotation. Background technique [0002] At present, there are two main types of vertical-axis wind turbines. One is the lift-type fan that uses the lift of the airfoil structure to do work. Its prototype is a Darrieus-type wind turbine. The manufacturing technology of most vertical-axis fans is On the basis of the operation principle of the airfoil structure, a little improvement technology is carried out; the other type is the resistance fan, whose prototype is the evolution of the wind cup wind meter, and the principle is to use the resistance of the front and back sides of the fan blade to the wind when it rotates horizontally Bad to do work. In the prior art, the wind energy utilization rate of the vertical-axis lift fan can be as high as 42% during normal operation, but it...
