Abstract

The invention relates to an automatic on-line detecting device for welding lines of a mast of a wind driven generator. The mast is a constituent part of a wind driven generating equipment system, is the main bearing component of a wind generating set, and is used for bearing the action force of cabin gravity, wind wheels and natural wind, and bearing the vibration load caused by the wind wheel rotation. The automatic on-line detecting device comprises a bottom rack (1). Both sides of the bottom rack are provided with crawler type wall climbers (2), and the bottom rack is provided with an electric control box (3). The electric control box is connected with an industrial camera (4), a motor (5) and a flaw detector (8), and is controlled by a remote controller (6). The flaw detector is connected with a probe module (7) through a conducting wire. The probe module and the flaw detector form a phased-array ultrasonic non-destructive system. The invention is used for the automatic on-line detection of the welding lines of the mast of the wind driven generator.

Description

Technical field: [0001] The invention relates to a special detection device for accurately detecting the weld seam quality of a fan tower; in particular, it relates to an automatic online detection device for a fan tower weld. Background technique: [0002] At present, wind power, as a clean new energy and renewable energy, has been paid more and more attention by the governments of various countries. Since 1993, the total installed capacity of wind power generation worldwide is 72.6GW. A report "Wind Power 12" jointly issued by the European Wind Energy Association and Greenpeace pointed out: According to experts' forecasts, by 2020, the total installed capacity of wind power in the world will reach 1.231 billion kilowatts, of which 170 million kilowatts will be generated in China, with a power generation capacity of about It is 3,000 billion kwh, accounting for 12% of the global electricity consumption in the same period. [0003] Then, with the significant increase in th...
