Description

A kind of semifloating shock reducing type vertical axis aerogenerator group
Technical field
The present invention relates to vertical axis aerogenerator technical fields, more particularly to a kind of semifloating shock reducing type vertical shaft wind Power generator group.
Background technique
Traditional energy is increasingly exhausted at present, develop that new energy is imperative, goes through within wind-power electricity generation existing more than 150 years History, scientist have found that the wind energy that the convection current air mass of low level air is included is very huge after analyzing atmospheric circulation model It is big, it is that the mankind are available and inexhaustible, one of the nexhaustible renewable sources of energy.Therefore, gradually aggravate in facing mankind In the case where energy crisis, also increasingly there is great and far-reaching realistic meaning for the research and development of wind-power electricity generation.? Some developed countries, such as the U.S., Holland, Denmark, France, Germany, state, Italy, wind-power electricity generation is in its domestic electric structure In played the important and pivotal role.And in China, only a small number of areas, as Xinjiang, Inner Mongol, Gansu, Guangdong Nan'ao And the ground such as ZhangZhou Dongshan Island of Shanwei Honghai Bay, Guangdong, Fujian are equipped with wind power station, total installation of generating capacity is less than 62000MW, accounts for China's electric structure ratio is not as good as 3%.Wind energy power technology also welcomes new opportunity to develop in this context, and countries in the world all exist It widelys popularize, China also has launched a series of support policy.
In the prior art, vertical axis aerogenerator is sorted out according to wind energy transformation principle, is broadly divided into resistance-type vertical axis Wind-driven generator and lifting-force type vertical-axis wind power generator.Resistance type vertical shaft wind driven generator mainly flows through leaf using air The resistance that piece generates is as driving force, and lifting-force type vertical-axis wind power generator is then the lift that blade generation is flowed through using air As driving force.Windage difference when resistance type vertical shaft wind driven generator is using contrary wind with the wind is done work, and revolving speed is lower, conversion effect Rate is low, and it is more that blade expends material, and usually requires separately to be equipped with speed increasing mechanism, causes cost excessively high;And lift vertical shaft Wind-driven generator is suitable for high tacho generator, and general microminiature unit can be used to directly drive generator, therefore its blade cost and power generation The cost of machine is below resistance type vertical shaft wind driven generator;Considered based on factors such as costs, lift vertical shaft wind-power electricity generation Machine becomes the development trend in industry.But lifting-force type vertical-axis wind power generator is generated in the high speed conditions of high wind Vibration problem, but at the bottleneck of the entire industry development of lifting-force type vertical-axis wind power generator.
Chinese invention patent (notification number CN 103912442A) discloses " a kind of vertical axis aerogenerator ", this is vertical Axis wind power generator includes blower unit and support shaft, and blower unit includes vertical dead axle, and the bottom end of vertical dead axle is equipped with first Flange, the top of support shaft are equipped with second flange, and two flanges are connected by screw bolt and nut, across first flange bolt hole It is cased with bolt sleeve on the bolt, the top of the bolt sleeve is cased with upper gasket, the scalariform of falling from power of the upper gasket in a ring, under Portion extends in the screw hole of the first flange, and top is located between the head and first flange upper surface of respective bolt, described The lower part of bolt sleeve is cased with lower gasket, and the lower gasket is between first flange and second flange.The connection structure realizes Being flexible coupling between two flanges can effectively act as damping effect in junction, keep away in the course of work of blower unit The loosening or damage for exempting from junction, extend the service life of wind-driven generator.
