Further, the power supply is the spring, the spring mounting is in the spring mounting box of the cabinet body to it is inconsistent with the fixture block, provides the restoring force for the motion of fixture block.

Furthermore, a plurality of bolt holes are formed in the fixing plate, and the fixing plate is installed on the wind turbine hub ladder frame through the bolt holes by bolts.

Further, a signal acquisition module, a power supply module and a plurality of sensors are installed in the cabinet body.

Compared with the prior art, the utility model, have following advantage and beneficial effect:

1. the wind turbine generator system data acquisition cabinet can change the position according to the actual demand of operation, and the position of stopping locking of the cabinet body can be adjusted in a flexible way promptly, increases the travelling comfort of operation, makes work humanized.

2. The gear is clamped by the clamping block mechanism only, so that the cabinet body is fixed, and the mechanical structure is simple, safe and reliable.

3. The whole wind turbine generator system data acquisition cabinet is simple in assembly, strong in applicability, economical and labor cost-saving.
