Embodiment Construction

[0056] There are many devices or systems currently used to monitor power generation blades, but some of them will be affected by the wind and cannot be accurately judged. The other part will be affected by the luminosity and cannot be accurately judged. In some cases, although the position of the crack can be accurately photographed, it is impossible to judge whether the crack meets the maintenance standard, because in many cases, the small crack does not need to be repaired immediately, and can be unified after it expands to a certain extent. repair.

[0057] Therefore, in order to solve the above-mentioned technical problems and technical effects, this embodiment discloses a crack detection system for wind power blades 3, such as figure 1 As shown, the column 2 is included, and the column 2 is erected on the ground. And the top of the column 2 is installed with a fan assembly, and the fan assembly is connected with a fan blade assembly through transmission. Specifically, ...

Abstract

The invention discloses a wind power generation blade crack detection system and a detection method thereof, and belongs to the technical field of wind power plants. When a current blade is in a first detection area, a camera acquires a first detection surface of the current blade; when the current blade is in a second detection area, the camera acquires a second detection surface and a fourth detection surface of the current blade; and when the current blade is in a third detection area, the camera acquires a third detection surface of the current blade. According to the invention, the accuracy of information is ensured, and because the information is not influenced by other environmental factors such as wind power, when the fan blade is in a certain detection area, the camera can continuously shoot an image of a certain detection surface; and data acquisition is carried out on the detection surface from different angles and then background processing is carried out to generate a leaf decomposition image, so that the phenomenon of incomplete acquisition or low precision caused by poor light is avoided.

Description

technical field [0001] The invention belongs to the technical field of wind farms, and in particular relates to a crack detection system and a detection method for wind power generation blades. Background technique [0002] Wind blades are an important part of wind power generation, as well as the force source and main bearing part of wind turbines. The safe and effective operation of wind turbine blades has an important impact on the power generation efficiency and operation safety of wind turbines. However, due to the long-term exposure of the wind blades, it is easy to cause damage to the blades after being baptized by high temperature, storms and even lightning and thunder. However, wind blades are relatively large in size and installed at a certain height, which is different from the inspection and maintenance of other small components. Relatively speaking, the inspection and maintenance of wind blades is more difficult. [0003] At present, ultrasonic testing technol...
