Description

Technical Field

[0001] The present invention relates to the technical field of workpiece detection devices, and in particular to a MW-level wind farm detection device. Background Art

[0002] At present, my country's wind power development strategy, wind power technology route, industrial policy and market mechanism are not yet perfect. The wind power industry's technological innovation capabilities are weak, lacking core technologies with independent knowledge, and low R&D capabilities for MW-class wind turbines. As a result, the testing methods in the production process of MW-class wind turbine components are also relatively backward.

[0003] Wind power generation has received widespread attention and high attention from the world as a clean and renewable energy source. Wind turbines are important parts of wind turbines. Most of them are arc-shaped or semi-arc-shaped. Holes are opened and fins are welded on the wind turbines. When in use, the wind turbines are spliced ​​into rings to transmit current. Wind turbines are large in size and various in shape, and cannot be detected by conventional detection methods.

[0004] At present, quality control mainly relies on experience, resulting in poor product consistency, high quality risk level, high scrap rate and low efficiency. After the wind turbine row is manufactured, the existing technology mainly relies on calipers and three-coordinate measuring to detect it. The ruler and gauge detection has great limitations and high errors, and it is impossible to complete the detection of the entire wind turbine row copper bar. In addition, the three-coordinate detection is expensive, the modeling is complex, the detection time is long, and the detection efficiency is low, which seriously restricts production efficiency and does not meet the requirements of industrial mass production.
