A kind of wind and light generator

Abstract

The invention provides a wind and solar generator which comprises a generator and a plurality of blades, wherein the blades are arranged on a rotating shaft of the generator, photovoltaic power generation panels are fixed on the blades, connecting shafts are fixed at the root parts of the blades, a spring mechanism is fixed on the rotating shaft of the generator, and the connecting shaft are connected with the spring mechanism. According to the wind and solar generator, the photovoltaic power generation panels are arranged on the blades, so that wind energy and solar energy are utilized fully; the spring mechanism is arranged, so that pitch variation of the blades is realized; the pitch variation of the blades is realized through a simple structure, and the cost is reduced; face areas of the blades are increased, and too-high speed of the blades is avoided, so that the generator or the blades can be prevented from being damaged; and at the same time, pitch variation is realized through the spring mechanism, so that the rotating speed of the blades is uniform. A plurality of concave-surface reflective mirrors are arranged on a supporting tower, light radiating on the concave-surface reflective mirrors is reflected to the photovoltaic power generation panels, so that solar energy and the photovoltaic power generation panels are fully used, and the power generation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to a wind and light generator. Background technique [0002] Wind energy and solar energy are both clean and extremely abundant renewable resources. Wind power generation is to use natural wind as power to drive the blades to rotate and drive the generator to generate electricity. When there is no wind, it cannot generate electricity. At the same time, in the prior art, the blades of wind power generators have fixed type and variable paddle type. Among them, the variable paddle type wind power generator can change the windward area of ​​the blades by changing the pitch of the blades. , to increase power generation and protect blades. At present, the pitch-changing structure of the blade generally adopts a motor to drive the blade to change the pitch. The pitch-changing structure is complicated, the cost is high, and power consumption is required at the same ti...
