Abstract

The invention discloses an ice preventing and removing system for a fan blade. The ice preventing and removing system comprises an air-heating ice preventing device, an expansion pipe ice removing device, an electric heating ice removing device, a layer ice removing device and a monitoring control device. The air-heating ice preventing device comprises a condenser, an air sending pipeline and an air guiding pipeline; the air sending pipeline is connected with the condenser and is used for sending hot exhaust air of the condenser into a fan hub and an engine cabin; and the air guiding pipelineis arranged at the fan hub and is used for guiding the hot air at the fan hub into the fan blade. The expansion pipe ice removing device comprises a plurality of expansion pipes which are distributedon the fan blade and are connected in parallel with one another. The electric heating ice removing device comprises a plurality of resistor wires which are distributed on the fan blade and are connected in parallel with one another. The layer ice removing device comprises a hydrophobic coating which is arranged on the fan blade. The monitoring control device comprises an ice prevention and removalcontrol module, an acceleration sensor, a temperature sensor and an optical fiber sensor, wherein the acceleration sensor, the emperature sensor and the optical fiber sensor are electrically connected with the ice prevention and removal control module. The system disclosed by the invention is high in energy utilization rate and ideal in accumulated ice removal effect.

Description

technical field [0001] The invention relates to the technical field of fan anti-icing and deicing, in particular to a fan blade anti-icing and deicing system. Background technique [0002] In the past ten years, my country's energy transformation process has been accelerating, and the wind power industry has achieved rapid development. my country has become the country with the largest installed capacity of large-scale wind power in the world. [0003] With the continuous improvement of wind power operation technology, the monitoring and operation and maintenance technology of wind turbines has also received more and more attention. Although the selection of wind turbines will be specially designed and manufactured according to the weather conditions in the selected area, the frequent occurrence of abnormal weather conditions also makes wind turbines exposed to the natural environment face many safe operation challenges. In my country, such as Hunan, Hubei, Guizhou, northea...
