Description

Support arm adjusting device of slide rail type multistage vertical wind power generation device

Technical Field

The utility model relates to a wind power generation technical field, concretely relates to multistage perpendicular wind power generation set's of slide rail formula support arm adjusting device.

Background

Wind energy is increasingly gaining attention as a clean renewable energy source in all countries of the world. The wind energy is huge, and the wind energy in the world is about 2.74 x 109MW according to statistics, wherein the available wind energy is about 2 x 107MW, which is 10 times larger than the total amount of water energy which can be developed and utilized on the earth. Wind energy has long been used, for example, to pump water, mill surfaces, etc. by windmills, and there is a growing interest in using wind energy to generate electricity.

In the thirties of the twentieth century, rotary wing technology in the aviation industry in Denmark, Sweden, Soviet Union and the United states of America has successfully developed small-sized wind power generation devices. These small wind power generators are widely used in windy islands and remote villages, and their power generation costs are much lower than those of small internal combustion engines. However, the current power generation of these small wind power generators is low, and is mostly below 5 kw. By 1 month 1978, a 200 kilowatt wind generator was built in the Cleaton town, New Mexico, USA, with a blade diameter of 38 meters, and the generation of electricity was sufficient for 60 residents. In early summer in 1978, the amount of generated electricity of a wind power generation device which is put into operation on the west coast of the peninsula in denland, danish reaches 2000 kilowatts, the height of a windmill is 57 meters, 75 percent of generated electricity is transmitted to a power grid, and the rest is supplied to a school nearby. In the first half of 1979, the united states in the blue mountain of north carolina has built up a wind turbine for generating electricity which is the largest in the world. The windmill is ten stories high, the diameter of the windmill steel blade is 60 meters, and the blade is arranged on a tower-shaped building, so the windmill can freely rotate and obtain electric power from any direction, and the power generation capacity can reach 2000 kilowatts when the wind speed per hour is more than 38 kilometers. China has no step to stop in the wind power generation business, and has achieved certain achievement, and particularly in the period of fifteen, the grid-connected wind power of China is rapidly developed. In 2006, the cumulative installed capacity of wind power in China has reached 260 ten thousand kilowatts, becoming one of the major markets for the development of wind power generation following Europe, the United states and India. In 2007, the wind power industry scale continues explosive growth situation in China, and about 600 ten thousand kilowatts are accumulated and installed in the whole country by the end of 2007. In 2008, 8 months, the installed wind power amount in China reaches 700 ten thousand kilowatts, which accounts for 1% of the total installed power capacity of the power generation in China and occupies the fifth world.

Wind power generators are classified by the direction of the rotation axis of their impellers, and have two major types, horizontal axis and vertical axis. At present, horizontal shaft type wind driven generators are in the mainstream form in domestic and foreign markets. However, the horizontal axis wind turbine has a great disadvantage. Such as: the horizontal axis type wind driven generator is high in installation height, large in occupied space, poor in wind resistance, large in noise during operation and high in starting wind speed (generally more than 3.5 m/s), and a yaw system facing the wind is required. Compared with a horizontal shaft type wind driven generator, the vertical shaft type wind driven generator can adapt to any wind direction, is lower in installation height, can be arranged in a connected mode, and occupies small space; in addition, the installation center of gravity of heavy components (such as a generator and a gearbox) is low, and the overall stability and wind resistance are good; the noise generated by the generator is low when the wind turbine runs, and the starting wind speed is low (about 2 m/s). Therefore, in recent years, vertical axis wind turbines have been receiving more and more attention.

The existing vertical axis wind power generation device mainly comprises a main shaft, an annular support, a supporting arm, a generator and an upright post. The stand is used for supporting annular support fixedly, support arm one end is connected with the main shaft rotation, the other end is connected with annular support rotation, the generator is fixed on the support arm, be fixed with the blade on the support arm, the blade absorbs the wind energy and drives the support arm rotation, the rotation of support arm drives the generator electricity generation, but among the present vertical axis power generation facility, contained angle between support arm and the main shaft is unadjustable, make the levelness of every support arm can not obtain guaranteeing, thereby it is different to cause the degree of compressing tightly of each support arm on annular support, make the rotational speed of support arm different, and then the generating efficiency who causes the generator on every support arm is different, be unfavorable for power generation facility work.
