Description

Technical Field

[0001] This utility model relates to the field of wind turbine frame equipment, and in particular to a lightweight wind turbine frame that is easy to install. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and expel gas. Fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings for ventilation, dust removal, and cooling; in boilers and industrial furnaces for ventilation and induced draft; in air conditioning equipment and household appliances for cooling and ventilation; in grain drying and conveying; as a wind source for wind tunnels; and for inflating and propelling hovercraft. A fan generally consists of a fan frame, impeller, and motor. The motor is located outside the fan frame, and the impeller is located inside the fan frame. The motor's output shaft is driven by the impeller's rotating shaft. When the motor drives the impeller to rotate at high speed, it draws air from outside the fan frame into the fan frame and expels air from inside the fan frame, thus achieving air delivery.
