Multi-wind-wheel multi-directional energy-collecting type wind power generator tower adopting multi-dimensional vibration damping devices

Abstract

The invention discloses a multi-wind-wheel multi-directional energy-collecting type wind power generator tower adopting multi-dimensional vibration damping devices, and belongs to the fields of wind power generation and structural earthquake resistance and wind resistance. The multi-wind-wheel multi-directional energy-collecting type wind power generator tower includes large blades, small blades,the gyro vibration damping devices, wind wheel connecting devices, a blade rotating device, a tower frame, the cantilever tuning vibration damping devices, an energy output cable, a limiting wall, gyro outer supporting shafts, a gyro rotor, a gyro inner supporting shaft, an annular frame tube, universal rolling spherical hinges, tuning mass blocks, cantilever racks, cantilever sections, transmission systems, gearboxes and the like. The multi-wind-wheel multi-directional energy-collecting type wind power generator tower is provided with the blades in multiple directions, so that the stressed area of a wind power generator is increased. When the wind direction is erratic, wind energy from all directions is simultaneously absorbed and converted into electrical energy, so that the use efficiency of wind power can be improved. The vibration damping devices are combined to more effectively improve the earthquake resistance capacity of the wind power generator under the action of wind load and ground earthquake motion, so that the wind power generator tower is enabled to perform wind power generation operation more safely and for a long time.

Description

technical field [0001] The invention relates to a multi-wind wheel and multi-directional energy-collecting structure using a multi-dimensional damping device for a wind power generator tower, and belongs to the field of wind power generation and structure anti-seismic and wind resistance. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, the demand for various resources and energy is also increasing. Among them, electric energy plays an essential role in human daily life. At present, the highest use efficiency and conversion rate is through the combustion of non-renewable resources such as coal and natural gas. Although these resources are relatively mature in use, their quantity is decreasing day by day. Therefore, finding other ways to obtain electric energy is an important engineering issue today. With the advancement of science and technology, people began to continuously research and dev...
