Embodiment 1

[0060] Such as figure 1 As shown, the high-efficiency vertical axis wind turbine in this embodiment includes a fixed tower 3 that determines the vertical axis of rotation, and the top of the tower 3 supports a wind wheel that is axially constrained and rotates horizontally; the wind wheel includes a wheel frame 1 with a rotation center, And the blades 2 distributed on the periphery of the wheel frame 1; the wheel frame 1 includes a rotating connector F located at the center of rotation and connected to the tower 3 in rotation, and an upper connection for connecting the upper part of the blade 2 is fixedly connected to the upper side of the rotating connector F The lower connecting part 9 for connecting the lower part of the blade 2 is fixedly connected to the lower side of the rotating connecting piece F, and the lower connecting part 9 is sleeved on the outer periphery of the tower 3; the lower connecting part 9 is a vertical axis of rotation A cone or a platform, the cone is...

Embodiment 2

[0067] Such as figure 2 As shown, the structure of the high-efficiency vertical axis wind turbine in this embodiment is basically the same as that in Embodiment 1, the difference is that:

[0068] (1) The lower connecting portion 9 adopts a second structure (such as Figure 28 shown): the lower connecting portion 9 includes a set of first transverse spokes, a set of radial spokes, a set of second transverse spokes, and a set of reinforcements 8 (such as Figure 19 As shown), the reinforcements 8 are triple (120°) rotationally symmetrically distributed around the vertical axis of rotation; the first transverse spokes are fixedly connected to form a six-fold rotationally symmetrical hexagonal upper bottom frame 6 with the rotating connector F as the center (Such as Figure 12 As shown), the vertices of the upper bottom frame 6 and the rotating connector F are respectively fixedly connected by radially arranged radial spokes S; the second transverse spokes are fixedly connecte...

Embodiment 3

[0075] Such as Figure 33 As shown, the structure of the high-efficiency vertical axis wind turbine in this embodiment is basically the same as that in Embodiment 1, the difference is that:

[0076] (1) The upper connecting part adopts the fourth structure: the cantilever B of the upper connecting part is a bent cantilever (such as Figure 4 shown), the cantilever B is formed by successively connecting the upper horizontal section, the inclined section and the lower horizontal section, and the inclined section is straight; the end of the upper horizontal section of the cantilever B away from the inclined section passes through the upper plate P in sequence U 1. The upper end fixing part E is connected to the upper end of the blade 2, and the other end of the lower horizontal section of the cantilever B away from the inclined section is fixedly connected to the top end of the support shaft A'; the upper connecting part also includes a tensile member formed by a group of transve...

Abstract

The invention relates to an efficient vertical axis wind turbine. The efficient vertical axis wind turbine comprises a fixed tower frame for determining the vertical rotating axis; a wind wheel which is axially restrained and horizontally rotated is arranged at the top end of the tower frame in a supporting mode and comprises a wheel frame with the rotating center and blades distributed on the periphery of the wheel frame; the wheel frame comprises a rotating connection part located in the rotating center and rotationally connected with the tower frame; an upper connecting portion used for being connected with the upper portions of the blades is fixedly connected to the upper side of the rotating connection part, a lower connecting portion used for being connected with the lower portions of the blades is fixedly connected to the lower side of the rotating connection part, and the tower frame is sleeved with the lower connecting portion; the lower connecting portion is in a shape of a cone or frustum with the vertical rotating axis as the center axis; and top point of the cone or the bottom surface, being smaller in area, of the frustum coincides with the plane where the rotating connection part is located. By improving the structure of the wind wheel, the performance of the wind turbine is improved.

Description

technical field [0001] The invention relates to a high-efficiency vertical axis wind turbine, which belongs to the technical field of wind turbine design and structure, as well as the development and design fields of renewable energy, energy saving and emission reduction, and environmental protection technologies. Background technique [0002] As far as the applicant knows, most of the wind turbines used in the current market are horizontal-axis turbine wind turbines with the rotor shaft placed horizontally, which belong to the category of high-wind-speed wind turbines. Average wind speed Areas of m / s run poorly. In addition, this type of wind turbine is noisy and produces infrasonic waves, which is not suitable for use in cities and communities, and it will also endanger the living environment of birds. [0003] The vertical axis wind turbine is characterized by no wind direction, no aerodynamic noise, and no infrasonic waves. It can use both the lift force and the thrus...
