A kind of anti-icing wind power generator blade and its preparation process

Abstract

The invention relates to the technical field of wind power generation, in particular to an anti-icing wind power generator blade and a preparation process thereof, in which a PVC heat-shrinkable film is provided on the wind power generator blade to prevent the wind power generator blade from being covered with ice under low-temperature weather conditions , including PVC heat-shrinkable film base material, the surface of the PVC heat-shrinkable film base material is subjected to CF 4 After etching, it becomes a rough surface with multiple grooves and pits, and a PTFE coating is deposited on the rough surface. The grooves, pits and PTFE coating form a tight cross-linked network micro-nano surface structure, which does not require The shutdown of the wind turbine does not affect the power generation of the wind turbine, saves manpower and material resources, does not need to be energized and heated, saves a lot of electric energy, does not affect the normal operation of the wind turbine, and fundamentally reduces the icing rate of the wind turbine blades, thereby Under the premise of not damaging equipment and wasting energy, the utilization rate of wind turbines in cold seasons can be improved to ensure the power generation in winter.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an anti-icing wind power generator blade and a preparation process thereof. Background technique [0002] Wind energy is a clean and renewable energy source. Our country is very rich in wind energy resources. At present, the wind energy reserves that can be developed are as high as 1 billion kilowatts, and the wind energy reserves on land alone reach 253 million kilowatts. Wind turbines can convert wind energy into mechanical energy, and then into electrical energy, alleviating the energy shortage caused by the combustion of oil, coal, and natural gas for power generation. Especially in grasslands, plateaus and coastal areas where energy is scarce or transportation is inconvenient, it is the general trend to use wind energy to produce clean electricity. Today, my country's wind power industry has entered a stage of rapid development, known as the world's first win...

AI Technical Summary

Problems solved by technology

[0009] To sum up, there are many wind turbines in China to produce clean electricity, but their blades are prone to frost in frosty weather, which increases the weight of the blades, reduces their efficiency, and even causes damage to machines and personnel

People have done a lot of work to improve this situation, such as installing resistance wires on the surface of the blades to heat the blades, etc., but this method wastes a lot of electric energy and does not fundamentally solve the problem of anti-icing
