Abstract

The invention discloses a wind generating set using bamboo blades, which comprises a wind wheel system, a drive system, a power generator and a pylon. An output end of the drive system is connected with the power generator and the drive system and the power generator are installed on the pylon. The wind wheel system comprises a wheel hub and blades which are fixed on the wheel hub. The revolving shaft of the wheel hub is connected with an input end of the drive system and the blades are made of bamboo composite materials. The invention provides a wind generating set applying bamboo blades, which improves the flexibility feature of the blade, prolongs the service life of the set, is environment-friendly and reduces cost.

Description

technical field [0001] The invention relates to wind power generating equipment, in particular to a wind power generating set. Background technique [0002] At present, most of the traditional blades made of glass fiber reinforced plastics are used in wind turbines. The material density of the blade made of glass fiber reinforced plastic is high, and the weight of the blade with the same length is heavier, and the flexibility is poor. This will lead to a relatively large load on the unit during operation, which will cause serious wear and tear on the parts and affect the life of the unit. [0003] Moreover, the main components of FRP blades are chemical raw materials such as glass fiber and resin. In the process of processing, grinding and assembling, not only will there be dust pollution, but also harmful substances will be released during the curing process, threatening the safety of production workers. healthy. In addition, glass fiber and epoxy resin in blade raw mater...
