Problems solved by technology

[0004] For wind turbines installed in alpine regions, due to the low temperature, their blades will freeze to varying degrees in winter, which directly affects the shape of the blades, and the unpredictable load changes will have an adverse effect on the fan system. Therefore, the problem of icing has been solved. Become one of the serious hidden dangers affecting the safe operation of wind turbines

Abstract

The invention discloses a deicing protection type wind power generation blade for an alpine region, and belongs to the field of wind power generation blades. The irregular cyclic movement process of amultiple-effect ball on a blade body is achieved by combining the centrifugal force of the blade body during rotation and the gravity acceleration of the multiple-effect ball, on the other hand, thefriction heat generation process is achieved through movement of the multiple-effect ball, heat is provided for the blade body through friction, the melting efficiency of ice and frost on the surfaceof the blade body is improved, meanwhile, an aeration rebounding device is extruded at intervals through the multiple-effect ball in the moving process, so that the aeration rebounding device pressurizes hot flow gas in the blade body, then the hot flow gas impacts the ice and frost on the surface of the blade body from inside to outside, crushing and melting of the ice and frost are promoted, andremoval of the ice and frost on the surface of the blade body is achieved through multiple benefits.

Description

technical field [0001] The invention relates to the field of wind power generation blades, and more specifically relates to a deicing protection type wind power generation blade used in high cold regions. Background technique [0002] Wind energy is a clean and renewable energy that is inexhaustible and inexhaustible. With the depletion of traditional fossil energy such as coal, oil, and natural gas, the development and utilization of wind energy has received more and more attention, and has become one of the most commercially valuable projects in the field of new energy. A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. The principle of wind power generation is to use the wind to drive the blades of the windmill to rotate, and then increase the speed of rotation through the speed increaser to drive the generator to generate electricity. [0003] Wind power blades are ...
