Example Embodiment

[0042] Example 1

[0043] Such as figure 1 As shown, this embodiment provides a real-time variable pitch wind wheel 1, which includes a wind wheel support 11, a wind blade 12, and a wind blade rotating shaft 13. At least three wind blades 12 are circumferentially arranged on the wind wheel support 11, and each wind blade 12 is rotatably connected with the wind wheel support 11 through the wind blade rotating shaft 13.

[0044] In this way, the wind propeller 12 can be evenly arranged on the wind wheel support 11 on the circumference. The hardware environment of the real-time variable-pitch wind wheel 1 is constructed. The wind wheel support 11 is the main body of the real-time variable-pitch wind wheel 1 when it rotates. The force of the wind blade 12 drives the wind wheel support 11 to rotate, and the wind blade 12 passes through the wind. The rotation of the propeller shaft 13 realizes the pitch change and changes the force of the real-time pitch change wind wheel 1.

Example Embodiment

[0075] Example 2

[0076] Please refer to Picture 8 This embodiment provides a vertical axis wind power generator, which includes a generator 2 and a wind wheel. The wind wheel is coaxially provided with an annular gear, and the input shaft of the generator is provided with a power take-off gear meshing with the annular gear .

[0077] In this embodiment, the wind wheel is the real-time variable pitch wind wheel 1 in embodiment 1. The wind wheel support 11 of the real-time variable pitch wind wheel 1 is coaxially provided with an annular ring gear 3, and the input shaft of the generator 2 is provided There is a power take-off gear 4 meshing with the ring gear 3. In other embodiments, the wind wheel may also be a vertical axis wind wheel with other structures.

[0078] As a result, the real-time pitch wind wheel 1 drives the generator 2 to rotate through the gear pair composed of the ring gear 3 and the power take-off gear 4, first converts wind energy into the kinetic energy of th...

Abstract

The invention provides a real-time variable-pitch wind wheel which comprises a wind wheel bracket, wind propellers and wind propeller rotating shafts. At least three wind propellers are arranged on the wind wheel bracket circumferentially. Each wind propeller is rotationally connected with the wind wheel bracket through the corresponding wind propeller rotating shaft. The real-time variable-pitchwind wheel further comprises a driving device which drives the wind propellers to rotate by driving the wind propeller rotating shafts, a sensing device which is used for sensing the wind environmentand the rotation condition of the real-time variable-pitch wind wheel, and a controller which is electrically connected with the sensing device and the driving device. The controller controls the driving device to operate according to parameters detected by the sensing device. The windward area of the wind propeller on the windward semi-circumference is larger than the headwind area of the wind propeller on the headwind semi-circumference through driving of the driving device. The invention also provides a vertical-axis wind turbine. The real-time variable-pitch wind wheel and the vertical-axis wind turbine have relatively high wind energy utilization rate and conversion rate, and the stress conditions of components of the wind propellers and the wind wheel bracket, which are split, are more reasonable.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a real-time variable pitch wind rotor and a vertical axis wind power generator. Background technique [0002] A wind turbine is an electrical device that converts wind energy into mechanical energy and mechanical energy into electrical energy. At present, large and medium-sized wind power mainly adopts horizontal-axis wind turbines, which are lift-type wind turbines, which have the advantages of high speed and high utilization rate of wind. The mainstream wind turbines currently in commercial operation are basically horizontal axis wind turbines. [0003] The wind turbines are supported by vertical towers. With the increasing capacity of horizontal axis wind turbines, the capacity of mainstream wind turbines has reached 2 MW to 3.5 MW. The weight of the cabin has reached 70-100 tons, and the height of the cabin has reached about 100 meters. The production, transportation a...
