Embodiment 1

[0057] A kind of wing-spreading double-swing-blade vertical-axis wind power generating set of the present invention, such as Figure 1 to Figure 4 As shown, the generator 11 and the wind wheel installed on the vertical shaft of the generator 11 are included, the generator 11 is installed on the tower column 12, the wind wheel includes a rotating bracket 7 and a plurality of groups of fan blade units, and the fan blade unit Including the fan blade 1 , the hinge mechanism and the strut 4 , the fan blade 1 is composed of an upper blade 101 and a lower blade 102 .

[0058] Wherein, one end where the upper blade 101 and the lower blade 102 are connected is provided with a hinge 14, the upper blade 101 is located above the hinge 14 and is provided with an upper lug 103, and the lower blade 102 is located below the hinge 14 and is provided with a lower lug. 104. Simultaneously, one end of pole 4 is provided with hinge joint 15; Hinge mechanism comprises the compression spring 5 that...

Embodiment 2

[0075] A wing-spreading double-swing-blade vertical-axis wind power generating set of the present invention is basically the same as Embodiment 1, the difference is that in this embodiment, the upper pressing roller and the lower pressing roller are arranged on the Inside the strut 4. There is sliding friction between the guiding mechanism 13 arranged in this way and the steel rope, and the resistance is relatively small.

[0076] The main technical solution of this embodiment is basically the same as that of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here.

Embodiment 3

[0078] On the basis of Embodiment 1 of the present invention, the hinged seat 9 is arranged in a triangular shape, and the hinged seat 9 is assembled with the second pin shaft 8 on the basis of Embodiment 1. One end is rounded. It should be noted that, in addition to being triangular, the hinge seat 9 of the present invention can also be set in other shapes, such as semicircular, rectangular, polygonal, as long as it can be provided with an opening that passes through the first pin shaft 3 and is connected with The pole 4 can be fixedly connected. The pole 4 and the rotating bracket 7 of the present invention are hinged through the hinge seat 9 and the second pin shaft 8, and the gyro effect is used to improve the stability of the vertical axis wind power generator. When the wheel rotates at high speed, the fan blade unit rotates upwards around the second pin shaft 8 and rotates in suspension. The whole wind wheel "rotates" around its own central axis like a spinning top. The...

Abstract

The invention discloses a rising double pendulum-blade vertical-axis wind generating set, comprising a generator and a wind wheel assembled on a vertical axis of the generator, wherein a fan blade is composed of an upper blade section and a lower blade section; a hinge element is respectively arranged at the connected ends of the upper blade section and the lower blade section; a hinge head is arranged at one end of a support rod; a hinge mechanism comprises a compression spring, a wire rope, a guide mechanism and a first pin shaft, which are transversely arranged inside the support rod; one end of the first wire rope and one end of the second wire rope are arranged inside the guide mechanism in a penetrating manner and connected with one end, far away from the fan blade, of the compression spring; the other end of the first wire rope is connected with an upper suspension loop; the other end of the second wire rope is connected with a lower suspension loop; the first pin shaft simultaneously penetrates through the hinge element of the upper blade section, the hinge element of the lower blade section and the hinge head of the support rod; the two blade sections of the fan blade rotate around the first pin shaft to adjust the windward area; the rotation angle and auxiliary fallback of the fan blade can be defined by using elasticity of the compression spring. The rising double pendulum-blade vertical-axis wind generating set is compact in structure, good in hinge, strong in wind resistance, and wide in wind speed range, and the generator is protected.

Description

technical field [0001] The invention relates to the technical field of vertical-axis wind power generators, in particular to a vertical-axis wind power generator with spread wings and double swing blades. Background technique [0002] In the prior art, there are two main types of vertical-axis wind turbines: one is a lift-type fan that utilizes the lift of the airfoil structure to do work, and its prototype is a Darrieus-type wind turbine. The manufacture of most vertical-axis wind turbines The technology is based on the operation principle of the airfoil structure with a little improvement. The vertical axis lift fan can use up to 42% of the wind energy during normal operation; the other is the resistance fan, whose prototype is the wind cup type The wind measuring instrument evolved, and its principle is to use the resistance difference between the front and the back of the wind blade to do work when it rotates horizontally. [0003] Vertical axis wind turbines do not nee...
