Solar energy and wind power combined power generating device

Abstract

The invention discloses a solar energy and wind power combined power generating device, which consists of fan blades, a generator, an accumulator battery pack and a bracket, wherein a plurality of groups of fan blades are arranged on the bracket, which is vertical to a bottom surface, by an outer sleeve and the generator is connected with the outer sleeve; the fan blades are formed by assembling and mounting small fan blades with leaflets, the lateral surfaces of the small fan blades are connected mutually to form a flat-plate fan blade; the small fan blades comprise frames and the leaflets which are connected with the frames by one end of each of rotating shafts; and the surfaces of the leaflets are photovoltaic components and the output ends of the photovoltaic power generating components are connected with the accumulator battery pack. The solar energy and wind power combined power generating device has the following advantages that: the wind direction is not required to be found, the wind power can be used maximally and the solar energy is complementarily used for generating power; the structure is simple, the cost is low, the solar energy and wind power combined power generating device is favorable for production, transportation, manufacturing, installation, maintenance and disassembly, and the using efficiency of the wind force is maximally improved; and the solar energy and wind power combined power generating device can meet the requirements on different working occasions and production, save the energy and reduce the emission and is environmentally friendly and convenient in large-scale production and popularization.

Description

technical field [0001] The invention relates to a wind power generation device, in particular to a loose-leaf plate type vertical axis wind power generation device which is not affected by changes in wind direction and can simultaneously utilize wind energy and solar energy. Background technique [0002] As renewable energy sources, wind energy and solar energy have a large amount of energy, are widely distributed, and will never be exhausted. They are clean and green to use, and can moderate the greenhouse effect. They are especially important for islands and remote areas with inconvenient transportation and far away from the main power grid. China's total wind energy is about 1.6 billion kilowatts, widely distributed in China's southeast coast, Inner Mongolia, Xinjiang and Gansu. The energy contained in solar energy is even more amazing. The 24h annual average radiation intensity at a certain point on the earth's surface is 0.20kw / m 2 , equivalent to 102000TW of energy ...

Problems solved by technology

However, the start-up wind speed of the turbine wind turbine is high, the noise is loud, the wind resistance of the blade is poor, and the adaptability of the blade to the wind direction is poor, and the power generation is easily affected by the change of the wind direction.

Moreover, the construction of the turbine-type wind generator requires a large amount of land and has electromagnetic radiation, and is generally not allowed to be built around cities. It is only suitable for building in deserts with vast land and sparsely populated areas, and cannot make good use of a large amount of wind energy around cities.

Moreover, solar energy is not utilized, wasting a large amount of available energy
