Problems solved by technology

[0003] The market for wind power generation is huge, and the technology is developing rapidly. Its core technology, wind blades and speed control systems, are ever-changing and varied. The wind blades are various and even oddly shaped, but they are all fixed. The windward and leeward areas do not change, so that wind energy utilization It is difficult to further improve the efficiency; and the speed regulation methods are generally eccentric method, deflection method and damping method, and the effect is not ideal. , not only will cause great damage to its own equipment, and the sudden stop of power generation will not only waste energy, but also often cause secondary damage to electrical machinery and machines

Embodiment Construction

[0035] For better understanding and implementation, the vertical axis wind power generation device with foldable blades and oil resistance speed regulation and control of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Please refer to the attached figure 1 Shown is a structural schematic diagram of a vertical axis wind power generation device with foldable blades, oil resistance speed regulation and control.

[0037] Please refer to the attached figure 2 Shown is a schematic diagram of the structure of the blade part in the vertical axis wind power generation device with foldable blades, oil resistance and speed regulation control. The foldable blade 2 of the blade part is installed on the shaft 1 and the bracket 6. Blades 7 and springs 8, the larger the windward angle of the system, the greater the stress area, and the smaller the leeward angle, the smaller the force area, thereby improving the efficiency of wind...

Abstract

The invention discloses a blade-collapsible, oil resistance-regulated and controlled vertical-spindle wind-driven generating device which is characterized in that blades are collapsible, the stressed area can be increased with the increase of a windward angle, and the stressed area can be reduced with the reduction of a leeward angle, thereby improving the effective rate of wind energy. By skillfully arranging an oil resistance regulation and control system between a spindle and a fixing mount (shell), the invention ensures more stable operation and avoids serious damage to equipment caused by emergency braking in an ultra-high wind speed situation and secondary damage possibly caused by sudden generation outage, thus the device provided by the invention is an excellent device which can not be subject to emergency braking and generation outage in an ultra-high wind speed situation.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a vertical axis wind power generation device with foldable wind blades and oil resistance speed regulation and control. Background technique [0002] The depletion of resources and the threat of global warming have led the world to reach a consensus that energy conservation and emission reduction is the best solution for sustainable development. Under this premise, research and application technologies for the development and application of wind energy, solar energy, and biomass energy have developed by leaps and bounds . [0003] The market for wind power generation is huge, and the technology is developing rapidly. Its core technology, wind blades and speed control systems, are ever-changing and varied. The wind blades are various and even oddly shaped, but they are all fixed. The windward and leeward areas do not change, so that wind energy utilization It is dif...
