[0023] A wind turbine vibration measuring device comprises a support frame 1, a wind turbine body 2 is mounted on the top of the support frame 1, a mounting frame 3 is fixedly mounted on one end of the top of the motor on the wind turbine body 2, a slide groove 301 is provided on the inner side of the mounting frame 3, through holes 302 are symmetrically provided at the edges of both ends of the top of the mounting frame 3, a connecting plate 4 is mounted inside the mounting frame 3, threaded holes 401 are symmetrically provided at the edges of both ends of the top of the connecting plate 4, a vibration velocity transmitter 5 is mounted on the top of the connecting plate 4, two wiring harnesses 6 are connected to the wiring terminals of the vibration velocity transmitter 5, and one end of the wiring harness 6 is connected to a UPS power supply 7.

[0024] Example, reference Figure 1 and Figure 2The top of the support frame 1 is fixedly connected to the bottom of the motor on the fan body 2 by bolts, and a rectangular plane is opened on the top of the heat dissipation cover on the motor, and a mounting frame 3 is arranged on the top of the plane, and the mounting frame 3 is welded to the top of the heat dissipation cover of the motor in an integral manner. The inner side dimension of the slide groove 301 inside the mounting frame 3 is the same as the outer dimension of the connecting plate 4, and one end of the slide groove 301 is provided with an opening, and a U-shaped notch is opened at the top, and one end of the connecting plate 4 is inserted from the opening of the slide groove 301 to slide to the inner side of the slide groove 301. At this time, the vibration speed transmission 5 is located on the inner side of the U-shaped notch on the slide groove 301, and the installation of the connecting plate 4 will not limit the position movement of the vibration speed transmission 5. After the connecting plate 4 is slidably installed on the inner side of the slide groove 301, the bottom edge of the through hole 302 located on the inner side of the slide groove 301 coincides with the edge of the threaded hole 401 on the top of the connecting plate 4, and bolts are used to pass through the through hole 302 from the top of the mounting frame 3 and be threadedly connected to the threaded hole 401 on the connecting plate 4.

[0025] Example, reference Figure 1 and Figure 3 There are two wiring harnesses 6, and the two wiring harnesses are divided into power lines and signal lines.
