Description
Technical Field
[0001] The present invention relates to the technical field of wind power generation equipment, and in particular to a wind blade detection device. Background Art
[0002] Blades are the most basic and critical components in wind turbines. Their good design, reliable quality and superior performance are the decisive factors to ensure the normal and stable operation of the unit. In wind turbines, the design of blades directly affects the conversion efficiency of wind energy and its annual power generation. It is an important part of wind energy utilization. There are two main processes used for large wind turbine blades: open mold manual layering and closed mold vacuum impregnation. The commonly used is closed mold vacuum impregnation. First, the reinforcement material is spread on the mold coated with silicone. In advanced modern factories, a special layering machine is used for layering, and then the basic resin is input by vacuum assisted impregnation technology. The cured blades are sent to the next process by automated equipment for grinding and polishing. Because the mold is coated with silicone, most blades no longer need to be painted.

The movable block 407 drives the driving block 405 to rotate through the connecting rod 406. The driving block 405 drives the connecting block 404 to rotate through the limit block. The rotation of the driving block 405 changes the angle between the limit block of the driving block 405 and the horizontal plane, and then changes the reciprocating distance of the extrusion rod 402 through the connecting block 404, and adjusts the force of the extrusion rod 402 to meet the detection requirements of the fan blade 2.
[0041] Start the travel motor 415, the output shaft of the travel motor 415 rotates to drive the intermittent gear 414 to rotate, the intermittent gear 414 drives the rotating rod 413 to rotate, the rotating rod 413 drives the linkage rod 403 to reciprocate through the arc frame 412, the linkage rod 403 drives the extrusion rod 402 to reciprocate through the connecting block 404 and the driving block 405, when the distance between the arc frame 412 and the upper surface of the bottom plate 1 is the shortest, the rotating rod 413 moves along the arc groove of the arc frame 412, at the same time, the intermittent gear 414 drives the full gear 416 to rotate, the full gear 416 drives the axle 417 to rotate through the belt drive, the axle 417 drives the travel wheel 418 to rotate, and the travel wheel 418 pushes the universal wheel 419 to move forward.
[0042] When the movable frame 401 moves forward, the slider 422 slides along the limit groove 424, the fixed rod 420 and the right-angle rod 421 slide relative to each other, and under the elastic force of the strong spring 423, the roller 426 contacts the leading edge A position of the fan blade 2, ensuring that the movable frame 401 moves along the leading edge A position perpendicular to the fan blade 2.
[0043] During the forward movement of the walking wheel 418, the round rod 430 is driven to rotate, the round rod 430 drives the rotating gear 431 to rotate, the rotating gear 431 drives the driven gear 432 to rotate through the gear transmission, and the driven gear 432 drives the scroll 433 to rotate, so as to facilitate scanning of the indentation at the leading edge A position of the fan blade 2. When the moving frame 401 moves forward, it drives the walking rod 428 to move. Under the action of the elastic force of the reset spring, the walking rod 428 moves forward along the indentation and scans the indentation onto the scroll 433 for easy recording.
[0044] When the indentation is greater than the standard value, the top rod on the walking rod 428 will touch the handle on the fan gear 4343, driving the handle of the fan gear 4343 to move. The rotation of the fan gear 4343 drives the first gear 4344 to rotate reciprocatingly, the first gear 4344 drives the second gear 4345 to rotate, the second gear 4345 drives the rotating block 4346 to rotate, the rotating block 4346 drives the iron block 4347 to rotate, the iron block 4347 is affected by the centrifugal force, the iron block 4347 contacts the lower shell 4342, and makes a sound, reminding the staff to check.
[0045] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
