Abstract

The invention provides a repairable electric heating ice-melting wind power generator rotor blade and a making method thereof. According to the repairable electric heating blade, a repairable carbon-fiber ice-melting electric heating chip is installed in the blade, and therefore the electric heating ice-melting function of the blade is achieved; meanwhile, the carbon-fiber ice-melting electric heating chip is made in a carbon fiber bundle warp and weft intersecting manner, the density of an electric current passing through the electric heating chip is adjusted by adjusting the density of carbon fiber bundles, and therefore heating temperature of the electric heating chip is adjusted. Meanwhile, by means of arrangement of a bidirectional latticed structure, warp carbon fibers are mutually connected through weft carbon fiber bundles, the warp carbon fiber bundles and the weft carbon fiber bundles form a whole in electrical performance, destruction resistance is high, and when a certain carbon fiber bundle breaks down, the heating property of the electric heating ice-melting chip is not affected; in addition, when multiple warp carbon fiber bundles are broken, the warp carbon fibers of the whole electric heating chip can be connected through the weft carbon fiber bundles, the disconnection range can be effectively narrowed, the non-heating area is decreased, and the ice-melting effect of the electric heating chip is guaranteed.

Description

technical field [0001] The invention belongs to the field of new energy technology and equipment, and in particular relates to a repairable electrothermal ice-melting wind power generator rotor blade and a preparation method thereof. Background technique [0002] Faced with the pressure of increasing population, people are paying more and more attention to energy issues. New energy sources such as wind energy and solar energy are gradually becoming an important way for people to solve energy problems. In the field of wind power generation, the commonly used equipment is a wind generator, and the rotor blades of the generator are the energy collection power devices of the wind generator. Therefore, the maintenance and maintenance of the blades is very important. [0003] Wind turbine rotor blades are used to collect wind energy and must be exposed to the natural environment. Therefore, when designing the blades, not only the influence of their own operation mode, but also the...
