Wind turbine blade gas bubble detection apparatus

Abstract

The invention provides a wind turbine blade gas bubble detection apparatus, which comprises a dark box, sliding grooves, a sliding block and the like, wherein a vertical rod is fixed on the bottom surface of the sliding block, and is connected to one end of a spring, the other end of the spring is connected to a photosensitive sensor, and a marking mechanism and a lighting device are arranged on the same side surface of the vertical rod. According to the present invention, the sliding block drives a sensing mechanism to move on the surface of a fan blade, the vertical rod on the sensing mechanism drives the marking mechanism and the lighting device to move, the photosensitive sensor can sense the shadow of gas bubble, and transmit the signal to a controller, the controller controls the running of a motor, the motor can drive a screw rod to move downwardly, the pigment box on the screw rod coats the surface of the fan blade with a pigment, the range of the gas bubble is marked by the pigment, picture comparison is performed through a picture taking method, and the gas bubble position can be confirmed with the wind turbine blade gas bubble detection apparatus if the taken picture isdifferent from a standard picture and the different area is large, such that the manual confirmation is avoided.

Description

technical field [0001] The invention relates to the field of fan blade detection, in particular to a wind power generator blade air bubble detection device. Background technique [0002] Fan blades are the main components of wind power generation equipment. During the production and processing of the blades, air bubbles may be formed on the surface of the fan blades. The existence of air bubbles will cause protrusions on the surface of the fan blades, destroying the original surface structure of the blades. In the process, the wind blows the blades to rotate, because the existence of air bubbles will affect the rotation speed of the blades, thereby reducing the power generation of wind power generation, so it is necessary to detect the position of the air bubbles on the blades before the fan blades are installed. The existing method of detecting air bubbles is to The surface of the fan blade is illuminated, and then the surface of the blade is photographed with a camera. If ...

[0002] Fan blades are the main components of wind power generation equipment. During the production and processing of the blades, air bubbles may be formed on the surface of the fan blades. The existence of air bubbles will cause protrusions on the surface of the fan blades, destroying the original surface structure of the blades. In the process, the wind blows the blades to rotate, because the existence of air bubbles will affect the rotation speed of the blades, thereby reducing the power generation of wind power generation, so it is necessary to detect the position of the air bubbles on the blades before the fan blades are installed. The existing method of detecting air bubbles is to The surface of the fan blade is illuminated, and then the surface of the blade is photographed with a camera. If there are air bubbles, the angle of light reflected by the blade surface is different from that of the blade without air bubbles. Therefore, the photos taken by the camera are also different. The fan blades to be detected Comparing the photos taken with the standard photos of fan blades can determine the position of the air bubbles on the blades. When comparing the photos with the camera, it is difficult to compare with the standard photos because the photos taken are messy. The photos are different. When the different range shown in the photos is relatively large, it is necessary to manually confirm the position of the bubbles, which increases the workload of the workers.
