Abstract
The utility model discloses an online non-contact detection device of fan blade defect. The device can realize the online non-contact detection function to aerogenerator high altitude department blade, and the device includes unmanned aerial vehicle, X light emitting device, X light receiving becomes looks device, bracket. The device can transport equipment to the blade position through unmanned aerial vehicle, make the blade between X light emitting device and receiving arrangement, emitter transmission X ray, receiving arrangement is responsible for the formation of image, detect with crackle or the deformation defect to blade surface and inside, unmanned aerial vehicle removes along the blade, can detect the different positions of blade, this equipment need not contact with the blade, can not harm the blade, in addition, blade surface or inside defect can all show on the image of receipt, the not enough of current surface photograph identification defect has been perfected.
Description
Technical Field
The utility model relates to a non-contact detection field of aerogenerator blade defect can realize the on-line measuring to fan blade in labour.
Background
Modern wind power generators are becoming more and more popular, many units in service are more than ten years, and various defects are generated in long-term operation of a fan blade, wherein cracks are typical defects directly related to the residual service life of the blade. Quality detection of blades of fans in service is important work, and current detection mainly relies on remote photography to identify surface cracks, but cannot detect internal cracks. There are also ultrasonic tests which require the equipment to be brought up to the fan, and contact tests which are prone to damage to the blades.
Disclosure of Invention
In order to solve the problem, the utility model discloses an online non-contact detection device of fan blade defect. The device can realize the online non-contact detection function to aerogenerator high altitude department blade, and the device transports equipment to the blade position through unmanned aerial vehicle, makes the blade between the X ray emitter and the receiving arrangement of device, and emitter transmission X ray, receiving arrangement are responsible for the formation of image, detect blade surface and inside crackle or deformation defect, and unmanned aerial vehicle removes along the blade, can detect the different positions of blade.
This online detection device of fan blade defect includes unmanned aerial vehicle, bracket, X ray emitter, X ray receiving imaging device, and their relation of connection is: the bracket is hung below the unmanned aerial vehicle, hang X ray emitter under the bracket respectively, X ray receiving and imaging device, unmanned aerial vehicle rises to the high altitude, make the blade be located X ray emitter, X ray receiving and imaging device between, its X ray emitter, there is a space region before the X ray receiving and imaging device, carry out on-line measuring to the blade defect of high altitude department, the bracket is adjustable, in order to adapt to the detection of different size blades, the image that X ray receiving and imaging device generated is saved on unmanned aerial vehicle, take off by unmanned aerial vehicle and carry out the analysis again.
The utility model has the advantages that: firstly, the device does not need to be in contact with the blade and does not damage the blade; secondly, defects on the surface or inside of the blade can be shown on the received image, and the defect that the camera can only detect the surface of the blade is improved.
Drawings
FIG. 1 is a structural layout diagram of an online non-contact detection device for detecting defects of fan blades, which comprises: unmanned aerial vehicle (1), X ray emitter (2), X ray receive image device (3), bracket (4).
Detailed Description
It should be noted that the embodiments and features of the embodiments of the present invention can be combined with each other without conflict.
The invention is described in detail with reference to the accompanying drawings in conjunction with the embodiments.
The detection process of the online detection device for the fan blade defects comprises the following steps: ground personnel pass through remote control operation unmanned aerial vehicle (1), make unmanned aerial vehicle fly to the blade position, adjust its position and make X ray emitter (2) and X ray receive imaging device (3) be located the both sides that are detected the blade respectively, start X ray emitter transmission X ray this moment, X ray receive imaging device receives the formation of image, can judge from above the image whether there is crack defect production in the blade.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, improvement, etc. within the principle of the present invention should be included within the protection scope of the present invention.
