Weak wind collecting power generation technology and device

Abstract

The invention provides a weak wind collecting power generation technology and device, belongs to the field of development and utilization of energy sources, and in particular relates to a power generation technology and device collecting weak wind by means of a wind direction tracing device and a high-strength and light and thin wind power converging arc-shaped hood. In order to solve the problemthat a wind power generation system cannot start a fan under a circumstance of low wind speed, the invention provides the weak wind collecting power generation technology and device. The device is internally provided with three small vanes different in diameter to increase the air quantity captured by the vanes in a weak wind condition effectively, so that the power generation efficiency of the wind power generation system is improved. The weak wind collecting power generation technology and device can break through limitation of wind speed capable of being used by an existing wind power generation technology, and achieves power generation in a weak wind condition, so that the economical efficiency of wind power generation is improved. The device is simply maintained and the output effectof energy sources is obvious. In addition, long-term stable development of wind power generation is guaranteed, the utilization efficiency of energy sources is improved favorably, and the energy shortage problem of China is alleviated.

Description

technical field [0001] The invention relates to a wind power generation technology and device, belonging to the field of energy development and utilization, in particular to a weak wind collection power generation technology and device. Background technique [0002] Wind energy is one of the non-polluting, renewable, and zero-cost clean energy sources. Effective use of wind energy can not only improve environmental problems, but also optimize resource allocation to solve the current energy shortage problem. At present, wind power generation technology is increasingly mature and widely used. The wind speed that can be used for power generation in the existing wind power generation technology is above 4m / s. However, the average wind speed in most areas of my country is lower than 4m / s. Resources cannot be fully and efficiently used. The construction of power stations capable of generating electricity under weak wind conditions (2-3m / s) can greatly improve the utilization of wi...
