Description

Technical Field

[0001] The utility model relates to the technical field of micro-wind power generation, and more specifically to a micro-wind power generation tree system based on the chimney effect. Background Art

[0002] Wind power generation refers to converting the kinetic energy of wind into mechanical kinetic energy, and then converting mechanical energy into electrical kinetic energy. Wind energy is a clean, pollution-free, renewable energy source with the advantages of good environmental benefits, renewability, short infrastructure cycle, and flexible installed capacity. Traditional wind power generation schemes have very high requirements for sites. Since existing wind power generation devices use large blades, they require greater wind power to drive and also occupy a larger space. When the wind direction changes, they need to turn accordingly to complete power generation. In areas where such conditions are not met, wind power cannot be used for power generation. Therefore, how to provide a micro-wind power generation tree system based on the chimney effect is a problem that technicians in this field urgently need to solve. Utility Model Content
