Abstract

The present invention provides a wind power generator, especially providing a medium or small sized wind power generator. The medium or small sized wind power generator is equipped with a plurality of blades rotating in the horizontal direction. The blades in the horizontal direction are less restricted by space and environment during operation, and can rotate with only weak wind. The blades are arranged radially while having an appropriate wind force, so as to increase the wind receiving area. But when the wind is increased to the condition that the wind power generator can not bear it, an adjustment/cushion mechanism is used to work so as to allow the blades to be closed to form an oval body. The blades with oval shape can enhance the effect of torsion; at this time, the wind receiving area is minimized so that the rotation speed of the wind power generator is naturally reduced. When the wind speed is stable, the radial arrangement of the blades is restored. By adjusting the blades to meet the wind force, the purpose of the protection of the wind power generator mechanism and the extension of the service life of the wind power generator can be achieved.

Description

Wind Turbines

The present invention provides a wind power generator, especially a medium and small wind power generator, and the medium and small wind power generators are provided with a plurality of blades rotating in a horizontal direction, and the horizontal blades are less restricted by space and environment during operation. It can be rotated with only a small amount of wind.

Industrial technology has made great progress, and a large part of it is attributed to the invention of electricity. Because electricity can be used by ordinary households and industries, with the rise of various manufacturing industries and the pursuit of smart home appliances, global electricity consumption is almost every year. All are growing, and therefore also cause a huge power gap. The main source of traditional electricity in each country is nothing more than thermal power generation and nuclear power generation. Thermal power generation must consume a lot of fuel, which will inevitably lead to the depletion of fuel resources and at the same time cause great air. Pollution; nuclear power generation is the most efficient energy source for power generation. However, with the global unscheduled nuclear energy disaster, people’s fear of nuclear energy has been strengthened, and the sound of anti-nuclear waves has also risen, causing countries to find alternative energy sources to replace the above two kinds. The main energy source.

Alternative energy, also known as green energy, is to use the various forces of the natural environment to promote generators or store electricity. The green energy is mainly solar energy, wind power, water power and ocean waves. The wind power system drives the blades to rotate and rotate through the wind. The mechanical energy is actuated by a generator to generate electrical energy. Generally, the large-scale wind turbine structure is a towering support column, and a vertical cross-shaped fan blade is arranged on the upper end of the support column to drive the blade to rotate by strong wind power. The large-scale wind turbines are large in size, high in cost, and limited in location (mostly by the sea or in areas with strong wind power), so they cannot be popularized. Furthermore, the blades of this large-scale wind turbine are fixed and cannot be adjusted with the wind direction and the strength of the wind. Therefore, when the wind conditions cannot be matched, the large-scale wind turbine cannot operate, which directly affects the power generation efficiency, season and gas. Hou's change has always been the biggest variable of green energy, and it is the goal of those who work in this industry to produce a pair of wind turbines with less influence on the external environment.

Therefore, in view of the above-mentioned problems and shortcomings, the inventors have collected such relevant materials through various evaluations and considerations, and have used the trial and modification of many years of R&D experience in this industry to start such small and medium-sized wind turbines. The invention patent was born.

The main object of the present invention is to provide a medium and small wind turbine, and the medium and small wind turbines are provided with a plurality of blades rotating in the horizontal direction. The horizontal blades are less restricted by space and environment during operation, and only need to be small. The wind can be rotated, and the blades are radially arranged when the wind is appropriate to increase the wind receiving area; but when the wind is increased to the wind turbine mechanism, the adjustment of the buffer mechanism is performed to close the plurality of blades. An ellipsoid is presented, and the blades have an elliptical shape to enhance the torsion effect. At this time, the area of the wind is minimized, and the speed of the wind turbine is naturally reduced. When the wind speed is stabilized, the blades return to the radial arrangement. The wind is adjusted by the adjustment of the blades to protect the wind turbine mechanism and extend the life of the wind turbine.

The secondary object of the present invention is that the wind turbine is provided with four air guiding sheets on the outside, and the single air guiding sheet has a wedge shape to generate a wind rectifying function, and the four air guiding sheets are symmetrically arranged to wind the wind generator. The axis of rotation is centered on two perpendicular intersecting extension lines.

Another object of the present invention is to provide a plurality of collecting blades on the outer sides of the blades for increasing the wind receiving area and the holding time when the blades are closed.

Another object of the present invention is to embed one of the first magnets of the same polarity in the blades, and to provide a second magnet with a plurality of polarities interlaced outside the wind generator to generate between the first and second magnets. The attracting and repulsive moments assist the blades to produce rotation and prevent the blades from overspeeding.

Another object of the present invention is to provide a first fixed disk above the first opening of the blade, the first fixed disk is connected to each blade through a rotating shaft, and the second fixed disk is disposed below the second opening. The second fixed disk is connected to each of the blades through a rotating shaft, and each of the blades is capable of arc-shaped swing between the first fixed disk and the second fixed disk.
