Embodiment

[0056] 1. After the inspection personnel drive the mobile vehicle 9 equipped with the blade dynamic inspection system of the present invention to the vicinity of the wind turbine 7 of the wind turbine that needs to be inspected by the blades, they check the lithium battery power of the UAV through the UAV battery compartment device 4, Whether the battery is faulty, and from the unmanned aerial vehicle battery compartment device 4, select the lithium battery that has been charged without failure and pack it into the unmanned aerial vehicle 8 placed on the unmanned aerial vehicle take-off and landing device 3 .

[0057] 2. The inspection personnel control the UAV take-off and landing device 3 to rise by operating the UAV control system 2 . It is also possible to operate the lifting platform controller 10 of the unmanned aerial vehicle landing device 3 which is provided separately to control the platform to rise.

[0058] 3. The inspectors prepare inspection tasks by operating th...

Abstract

The invention discloses a wind driven generator blade dynamic inspection system and method. The system comprises an airborne fault recognition system, an unmanned aerial vehicle control system, an unmanned aerial vehicle take-off and landing device, a data processing system, an unmanned aerial vehicle and a moving vehicle, wherein the airborne fault recognition system comprises a dynamic positioning device and an image acquisition device, the airborne fault recognition system is arranged on the unmanned aerial vehicle, and the image acquisition device and the dynamic positioning device carry out image real-time dynamic data acquisition on blades of a wind generating set; the airborne fault recognition system is in interactive connection with the data processing system; and the unmanned aerial vehicle control system and the unmanned aerial vehicle take-off and landing device are both arranged on the moving vehicle, and the unmanned aerial vehicle control system is in man-machine interaction connection with the unmanned aerial vehicle. The dynamic positioning device and the image acquisition device are arranged to perform image acquisition on the blades of the wind turbine generatorsystem in a non-stop state of the wind turbine generator system, so that the blade image information of the wind turbine generator system can be accurately acquired, and then fault diagnosis is performed through an image recognition technology.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, in particular to a dynamic inspection system and method for blades of a wind power generator. Background technique [0002] With the gradual maturity of the wind power market, more than 120,000 units of onshore wind power units have been put into operation at an annual growth rate of 10%; about 1,000 offshore wind power units are in operation and are put into operation at a doubling rate every year. Large-scale wind turbines have appeared one after another, and the blade length has also increased from the original 40m-60m to 60m-120m. The traditional blade detection methods are telescope observation and rope rappel manual detection, which have the following disadvantages: [0003] (1) The detection efficiency is low and the labor intensity of workers is high; [0004] (2) High-altitude operation, high detection cost; [0005] (3) The detection time is long, and the power generati...
