Anti-icing wind power blade and preparation method of anti-icing wind power blade

Abstract

The invention discloses an anti-icing wind power blade and a preparation method of the anti-icing wind power blade. The anti-icing wind power blade comprises a monitoring system, a peripheral power supply and a blade body provided with a macromolecule electrothermal film, wherein the macromolecule electrothermal film is arranged between the surface of a suction surface shell body and the surface of a pressure surface shell body of the anti-icing wind power blade or between shell body layers of the anti-icing wind power blade in a clamped mode, and the macromolecule electrothermal film is controlled by the monitoring system through a wire to be connected or disconnected with the peripheral power supply. At the time of operation, the monitoring system monitors icing parameters of an environment where the blade body is located, the peripheral power supply is connected when the icing parameters meet preset icing conditions, the macromolecule electrothermal film is powered on to emit heat, the heat is transmitted to the surface of the blade body, and the blade body is prevented from icing. According to the anti-icing wind power blade and the preparation method of the anti-icing wind power blade, the anti-icing wind power blade can be prevented from icing in an online mode under the condition of no machine halt, non-planned machine halts can be reduced, and wind energy utilization efficiency of a wind machine in frigid weather is improved. The anti-icing wind power blade is simple in preparation technology, high in operability, and free from extra complex processes and devices. The preparation method can be used for preparing a large anti-icing wind power blade. The anti-icing wind power blade and the preparation method of the anti-icing wind power blade are beneficial to popularization and implementation.

Description

technical field

[0001] The invention relates to a wind power blade and a preparation method thereof, in particular to an anti-icing wind power blade and a preparation method thereof. Background technique

[0002] Wind energy is a very important safe and clean energy with huge reserves, and wind power generation is the main form of wind energy utilization. my country's wind resources are mainly distributed in the Three North (Northeast, Northwest, and North China) regions with ice and snow and the coastal areas with very high humidity, and the environment is extremely harsh. When wind turbines are installed in these areas, when the wind turbine blades operate at zero degrees Celsius or below zero degrees Celsius, they will freeze if they encounter humid air, rain, ice and snow, especially supercooled water droplets. The icing problem of wind turbine blades is one of the main factors affecting its safety and reliability. After the wind turbine blades are covered with ice, it...
