Abstract

A system for transporting wind turbine blades includes a frame assembly for retaining a set one or more wind turbine blades and a plurality of inflatable devices coupled to the frame assembly.

Claims

1. A system for transporting a set of one or more wind turbine blades, comprising:

a frame assembly that forms an interior area that in turn retains the set of one or more wind turbine blades therein, the frame, having;

a top rack having side members integral with a bottom member and configured to form a U-shaped structure; and

a bottom rack having side members integral with a bottom member and configured to form a U-shaped structure;

wherein the side members of the top rack are releasably attached to the side members of the bottom rack via a plurality of connectors positioned at a plurality of ends of the side members of the bottom rack and the side members of the top rack;

wherein, when assembled, the top rack and the bottom rack form a rigid enclosed structure for carrying the set of one or more turbine blades within the interior area;

a support bracket secured to the bottom rack;

a mechanical fastener removably secured to the support bracket and configured to directly attach an end of one of the one or more turbine blades to the support bracket;

a plurality of inflatable devices disposed within the interior area and coupled to the frame assembly, the plurality of inflatable devices being inflated to support a portion of the one or more wind turbine blades and the plurality of inflatable devices are pre-formed to the specific contouring of the one or more wind turbine blades when the plurality of inflatable devices are inflated; and

a flexible tension member positioned within the interior area and configured to support and retain the set of one or more wind turbine blades;

wherein the combination of the plurality of inflatable devices and flexible tension member support and retain the set of one of more wind turbine blades in a relatively fixed position during transport.

2. The system according to claim 1, wherein the frame assembly is configured for releasable attachment to a support structure, and wherein the support structure is coupled to a mode of transportation.

3. The system according to claim 1, further comprising:

an enclosure component that is configured for releasable attachment to the frame assembly to form an enclosure.

4. The system according to claim 3, wherein the enclosure is configured to be stacked with another enclosure.

5. The system according to claim 3, wherein the enclosure component is releasably attached to the frame assembly by one or more quick-release devices.

6. The system according to claim 5, wherein the one or more quick-release devices comprises:

at least one of a bayonet-type twist-lock device and an inter-box connector.

7. The system according to claim 1, wherein the plurality of inflatable devices comprise:

a plurality of air bags.

8. The system according to claim 1, wherein a shape of at least one of the plurality of inflatable devices conforms to a shape of a specific portion of at least one of the one or more wind turbine blades when the at least one of the plurality of inflatable devices is inflated.

9. The system according to claim 8, wherein a degree of inflation associated with the at least one of the plurality of inflatable devices determines a degree of conformity to the shape of the specific portion of the at least one of the one or more wind turbine blades when the at least one of the plurality of inflatable devices is inflated.

10. The system according to claim 1, wherein the flexible tension member comprises:

at least one KEVLAR belt.
