Embodiment 1

[0042] refer to figure 1 , The automatic opening and closing blade wind power generation equipment includes a fixed base 100, a power generation device 200, a blade module 300, a locking device 400, an opening and closing device 500, a wind speed sensing device 600, a control device 700 and an energy storage device 800. The wind speed sensing device 600 monitors the wind speed of the environment, the control device 700 controls the operation of the opening and closing device 500 according to different wind speeds, and changes the degree of opening and closing of the fan blade module 300, and the fan blade module 300 rotates under the action of the wind to make the power generation device 200 To generate electricity, the energy storage device 800 can store electric energy.

[0043] refer to figure 1 , the fixed base 100 is fixedly placed on the ground. In this embodiment, the fixed base 100 is in the shape of a hollow prism, and the control device 700 and the energy storage de...

Embodiment 2

[0051] refer to Figure 7 The difference between this embodiment and Embodiment 1 is that: there are multiple groups of fan blade modules 300, and the fan rods 310 in the plurality of groups of fan blade modules 300 are fixedly connected coaxially. By arranging multiple sets of fan blade modules 300, the utilization rate of wind energy is further improved.

Embodiment 3

[0053] The difference between the present embodiment and the first embodiment is that the fan blade 320 includes an integrally formed enclosing portion 321 and two enclosing portions 322 , and the enclosing portion 321 is located between the two enclosing portions 322 . The enclosing part 322 is a flat plate structure arranged horizontally, and the closing part 321 is a plate-shaped structure arranged vertically. The closed parts 321 of the two fan blades 320 can be rotated to form closed patterns such as ellipse, rectangle and polygon.

Abstract

The invention relates to the field of wind power generation, in particular to wind power generation equipment with automatic opening and closing type fan blades. The wind power generation device comprises a fixed base fixedly placed on the ground, a power generation device and a fan blade module are arranged on the fixed base, the fan blade module comprises a wind rod and two fan blades, the wind rod is rotationally connected with the fixed base and used for driving the power generation device to generate power, and the two fan blades are rotationally and symmetrically arranged relative to the axis of the wind rod. And the fan blades are rotationally connected with the wind rod. The method has the effect of improving the wind energy utilization rate.

Description

technical field [0001] The present application relates to the field of wind power generation, in particular to an automatic opening and closing wind blade wind power generation equipment. Background technique [0002] Wind energy is a clean and pollution-free renewable energy. A wind turbine is an electric device that converts wind energy into mechanical work, drives the rotor to rotate through the mechanical work, and finally outputs electric energy. Wind power generators generally include components such as wind rotors, generators, and energy storage devices. The wind rotor rotates under the action of wind force, and converts the wind energy into the mechanical energy of the wind rotor shaft, and the generator rotates to generate electricity under the drive of the wind rotor shaft. [0003] In the existing wind turbine power generation technology, under extreme weather such as typhoon weather, the fan is easily damaged due to excessive wind force. Therefore, when design...
