Wind driven generator blade anti-freezing device and method

Abstract

The invention discloses a wind driven generator blade anti-freezing device and method. The wind driven generator blade anti-freezing device comprises a wind power generation system and a lifting shielding system. The wind power generation system is used for converting wind energy into electric energy. The lifting shielding system is arranged on blades of the wind power generation system and used for shielding rain and snow. The lifting shielding system comprises an upper and lower fixing ring, a slideway groove, rollers, shielding cloth, a direct-current motor and a lifting rope. The upper and lower fixing ring comprises an upper fixing ring and a lower fixing ring, The upper fixing ring and the lower fixing ring are respectively arranged at upper and lower ends of the blade. The slideway groove is formed between the upper fixing ring and the lower fixing ring, the rollers are arranged in the slideway groove, and the rollers are in sliding connection with the sliding way groove. The rollers are connected with the shielding cloth. The shielding cloth is laminated at the upper end of the lower fixing ring in an initial state. The direct-current motor is arranged on the upper fixing ring, an output shaft of the motor is connected with a lifting rope, and the lifting rope is connected with the rollers in a penetrating and buckling mode. It is guaranteed that a fan generator set is not affected by severe weather, and the service life of blades is prolonged.

Description

technical field [0001] The invention belongs to the application field of new energy wind power generation, in particular to a wind power generator blade antifreeze device and method. Background technique [0002] As countries around the world pay increasing attention to issues such as energy security, ecological environment, and climate change, accelerating the development of the wind power industry has become a common consensus and concerted action by the international community to promote energy transformation and development and respond to global climate change. As of the end of 2020, my country's installed wind power capacity has reached more than 200GW, and it has remained the first in the world since 2008, accounting for 32.24% of the world's cumulative installed wind power capacity. [0003] Wind power resources are particularly abundant in plateaus, cold, ridges, and mountaintops, and have great development value. However, these places are high in altitude, high in h...
