Description

Wind-powered electricity generation blade root strenghthened type connection structure Technical Field The invention relates to the field of fixed assembly of wind power equipment, in particular to a wind power blade root reinforced connecting structure. Background The wind power generation means that the kinetic energy of wind is converted into mechanical kinetic energy, and then the mechanical energy is converted into electric kinetic energy, the wind wheel rotates under the action of wind force, the kinetic energy of wind is converted into mechanical energy of a wind wheel shaft, and the generator rotates to generate electricity under the drive of the wind wheel shaft, so that the wind power generation device is an important form of wind power utilization. Devices required for wind power generation, called wind generating sets, can be largely divided into three parts of wind wheels, generators and towers. Before the principals, chinese people use the sails to provide power for the ship. In 1887, scotland james brains first used a windmill to charge the battery. In 1888, the first wind power plant was built in cleveland, usa. In 1891, the Danish pneumologist's Saint Luola. Kull introduced the aerology principle, and designed and built the wind power generator of the first modern meaning in the world. In 1941, the world's first MW wind turbines were invented in the United states Vermont and connected to a local grid. The wind driven generator blade is one of core components of the wind driven generator, the manufacturing cost of the wind driven generator blade is about 15-20% of the total cost of the wind driven generator, the design quality of the wind driven generator blade directly relates to the conversion efficiency of wind energy, annual energy generation of the wind driven generator blade is directly influenced, and the wind driven generator blade is an important ring for wind energy utilization. The first wind turbine which runs automatically and is used for generating electricity is built by Charles F.Brush of America in 1888, and the fan blade of the wind turbine adopts a flat plate design, so that the efficiency is low. In 1891, danish Poul LaCour introduced aerodynamic concepts when designing fan blades, found a wind turbine with rapid rotation and small number of blades, thereby creating a more scientific design method for fan blades, and for convenience in fixing, a wind power blade root reinforced connection structure is needed.
