Wind power blade deicing system and method based on unmanned aerial vehicle

Abstract

The invention discloses a wind power blade deicing system and method based on an unmanned aerial vehicle. The unmanned aerial vehicle can be flexibly operated, and the wind power blade is comprehensively shot through the infrared camera, so that the freezing point is found. An RTK positioning system accurately positions and records coordinate information of a freezing point of the wind power blade, the omnidirectional radar system can control the unmanned aerial vehicle to hover near the freezing point, the safe distance between the unmanned aerial vehicle and the wind power blade is 2.5 m, and damage to the wind power blade due to shaking of the unmanned aerial vehicle is avoided; the steering engine can adjust the directions of the sprayer and the nozzle to ensure the spraying accuracy; An FPV camera shoots the ice melting and removing process in the whole process and transmits the image to the operating handle screen in real time, so that the ice removing and cleaning process is timely and efficient; A ground system can provide power guarantee and signal guarantee for the mooring unmanned aerial vehicle, and the unmanned aerial vehicle can execute a deicing task in a high-altitude long-endurance and high-response mode.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to an unmanned aerial vehicle-based wind power blade deicing system and method. Background technique [0002] With the increasingly serious global environmental problems and energy crisis, clean energy has attracted more and more attention from all countries. As a kind of renewable energy, wind energy has huge reserves, wide distribution and great potential for development and utilization. [0003] The working environment of wind turbines is outdoors where wind resources are relatively abundant, and in some wind farms with high ambient humidity, large precipitation, and low temperature, when the temperature drops below zero degrees Celsius, ice may form on the wind turbine blades , the ice adheres to the blades and changes the airfoil of the blades, which not only affects the aerodynamic performance of the blades, reduces the power generation efficiency of...
