[0025] In this embodiment, the outer threading tube 12 is connected to the inside of the sleeve 5 via a damping pad 15 connected to the outside, and the outer threading tube 12 is positioned and adjusted via the damping pad 15 .

[0026] In this embodiment, the lifting mechanism 8 includes a support platform 9, a vertical bracket 10, a material tray 11 and an electric cylinder 13.

[0028] In actual application, this wind turbine heat dissipation performance test bench includes the following work contents:

[0029] Step 1: The operator first installs the generator on the top of the material tray 11, then passes the bolts through the bottom of the material tray 11 to fix the bottom of the generator, and opens the electric cylinder 13 to drive the vertical bracket 10 to rise vertically, so that the vertical bracket 10 is vertically lifted inside the support platform 9, so that one end of the generator is aligned with the temperature sensing module 6;
