Abstract

The invention relates to a deicing wind power blade heating system detection device and method. After the deicing wind power blade heating system is started to be in a working state, an unmanned aerial vehicle visible light imager and an infrared thermal imager are controlled to synchronously shoot a visible light image and an infrared thermogram of one same area of a wind power blade; an area corresponding to the shot image on a wind power blade heating element position distribution diagram is determined by utilizing the visible light image, the infrared thermogram is superposed with the area, the positions of heating elements are calibrated on the infrared thermogram, temperature data corresponding to the positions of the heating elements are compared, and when the percentage that the temperature of the positions of parts of heating elements is lower than the corresponding temperature of the other heating elements exceeds a set threshold value, it is judged that the parts of heatingelements fail. The method is less influenced by the environment temperature, and the detection result is more accurate. The deicing wind power blade heating system can be remotely detected, manpower is saved, efficiency is improved, and safety is higher.

Description

technical field [0001] The invention relates to a detection method of a wind power blade, in particular to a detection device and method for a heating system of a deicing wind power blade. Background technique [0002] Wind power is a kind of clean energy, which has attracted worldwide attention in recent years. Wind turbine blades are one of the important components of wind turbines, and their surface conditions have an important impact on the operation of wind turbines. In the cold winter, the surface of wind turbine blades is easy to freeze during actual operation, which not only reduces the aerodynamic efficiency of the airfoil, but also affects the availability of the unit. The anti-icing / deicing technology of wind turbine blades has become an important factor considered in the design of wind turbines. Different methods of heating anti-icing / deicing have been described in many patents, such as patent No. CN:200920000677.X using resistors to generate heat Anti-icing / de...
