DEVICE AND METHOD FOR TRANSPORTING AND STORING A WIND TURBINE BLADE

摘要

The invention proposes a device (1000) and a method for storing and transporting a wind turbine blade (100). The blade (100) is inserted between an upper structure (220) and a lower structure (240) applying a clamping force on the blade surface. The magnitude of the clamping force can be adjusted by means of a device (400) comprising an elastic member (440) arranged between the upper structure (220) and the lower structure (240) during operation. The magnitude of the elastic force exerted by the elastic element (420) is proportional to the magnitude of the clamping force. Furthermore, the magnitude of the elastic force linearly depends on the amount of compression of the elastic element (440) with respect to a characteristic rest length.

主权项

1. A clamping device for storing and transporting a wind turbine blade comprising:
a first structure and a second structure adapted to abut onto opposite sides of said wind turbine blade; a clamping force adjustment device permitting adjustment of the magnitude of the clamping force exerted by said first structure and said second structure onto said wind turbine blade;wherein said clamping device comprises:
an elastic member arranged between said first structure and said second structure so as to apply to said first structure and said second structure an elastic force with a magnitude having a predetermined and univocal dependency on the amount of deflection of said elastic member with respect to a characteristic rest length, the magnitude of said clamping force being proportional to the magnitude of said elastic force; and a biasing mechanism adapted to deflect said elastic member, so as to permit adjustment of the magnitude of said elastic force.
