Description

Technical Field

[0001] The invention belongs to the technical field of blade deicing, and in particular relates to a wind turbine blade deicing device. Background Art

[0002] As we all know, in the field of wind power generation, wind turbines are often installed in high-cold, high-humidity and other icing-prone environments. Once the wind turbine blades are frozen, many problems will arise. The ice layer on the blade surface adds extra weight, causing uneven force on the blades, aggravating fatigue wear and reducing their service life; at the same time, it changes the aerodynamic shape of the blades, reduces the efficiency of wind energy capture, and affects the power generation. A wind turbine blade de-icing device came into being. It is a type of equipment designed to promptly remove the ice layer on the blades to ensure the stable and efficient operation of the wind turbine, which is of great significance to the wind power industry.

[0003] At present, a Chinese invention with publication number CN110748463B discloses an offshore wind turbine blade deicing device, which relates to the field of wind power generation technology. An ice detection sensor is installed on the surface of the blade. When the blade is frozen, a variable frequency fully automatic booster pump receives an electrical signal from the ice sensor and starts working, pumping seawater containing a certain proportion of organic salts and bioglycerol in the water tank to the nozzle through a water pipe. The high-salinity seawater containing bioglycerol has zero harm to the marine biological environment, and has a freezing point of -30℃ to -40℃ and high ice melting performance. The control system equipped with a color-sensitive sensor has a simple structure, can effectively monitor the entire water spraying process, and achieve efficient and rapid deicing.

[0004] An existing wind turbine blade deicing device has the following disadvantages when in use: 1. When deicing wind turbine blades in a low temperature and high humidity environment, due to the lack of an automatic preheating structure for the blades, the blades cannot be automatically preheated, reducing the efficiency of deicing the blades; 2. When deicing wind turbine blades in a low temperature and high humidity environment, due to the lack of a drying structure for the blades after deicing, the blades cannot be dried and antifreezed, which reduces the flexibility of deicing the blades.
