Reliability test device for large-megawatt wind turbine cabin cover

The utility model relates to a reliability test device for a large megawatt wind turbine cabin cover, which comprises a device body, a device body fixing platform and a rotating platform, the rotatingplatform is positioned at the upper part of the fixing platform, and the outer side of the rotating platform is used for installing the cabin cover; the middle of the bottom face of the rotating platform is rotationally connected with the fixed platform through a connecting mechanism, and the two sides, used for rotating movement, of the bottom face of the rotating platform are further connectedwith the fixed platform through a plurality of sets of elastic supporting assemblies and at least one set of telescopic driving mechanisms respectively. The cabin cover fatigue testing device is reasonable in structural design, the reliability testing device can simulate severe environments such as strong wind, rain, snow and vibration, a cabin cover fatigue damage mode can be detected, and the fatigue life and the reliabi
