Abstract

A facility for manufacturing a rotor blade of a wind turbine is provided. The facility includes an injection machine for injecting an injection material into a mold to form the rotor blade, a movable tank system for accommodating precursor material to be supplied to the injection machine for preparing the injection material, wherein the movable tank system has wheels for moving the tank system. Further, a method for setting up a facility and a method for manufacturing a rotor blade are described.

First claim

The invention claimed is:

1. A facility for manufacturing a rotor blade of a wind turbine, the facility comprising:
an injection machine for injecting an injection material into a mould to form the rotor blade;
a movable tank system for accommodating precursor material to be supplied to the injection machine for preparing the injection material,
wherein the movable tank system has wheels for moving the tank system, and
wherein the facility is adapted to perform a Vacuum Assisted Resin Transfer Moulding process for manufacturing the rotor blade.

2. The facility according to claim 1 , further comprising
a releasable pipe for releasably interconnecting the tank system with the injection machine for guiding the precursor material from the tank system to the injection machine.

3. The facility according to claim 1 , further comprising the mould,
wherein the mould comprises a first mould portion and a second mould portion, which are assimilable for providing an inner shape complementary to an outer shape of the rotor blade when injecting the injection material into the mould and curing the injection material within the assembled first mould portion and second mould portion, and which are detacheable from each other for enabling releasing the cured injection material from the mould.

4. The facility according to claim 1 , further comprising:
at least one crane for moving a first mould portion and a second mould portion, for assembling the first mould portion and the second mould portion with each other and for disassembling the first mould portion and the second mould portion from each other.

5. The facility according to claim 1 , further comprising: at least one crane for moving a first mould portion and a second mould portion, for assembling the first mould portion and the second mould portion with each other or for disassembling the first mould portion and the second mould portion from each other.

6. The facility according to claim 5 , further comprising:
a releasable electrical interconnection system for releasably operatively, in particular pairwise, interconnecting components of the facility, selected from the group consisting of the injection machine, a first supply unit, a second supply unit, the crane, a energy supply unit and a control unit.

7. The facility according to claim 5 , further comprising:
a releasable electrical interconnection system for releasably operatively pairwise interconnecting components of the facility, selected from the group consisting of the injection machine, a first supply unit, a second supply unit, the crane, a energy supply unit and a control unit.

8. The facility according to claim 1 , wherein the movable tank system comprises:
a first tank for accommodating thermosetting material,
a second tank for accommodating a cross-linking material for enabling cross-linking of the thermosetting material after mixing the thermosetting material with the cross-linking material to form the injection material, and
wherein the first tank has first wheels for moving the first tank and the second tank has second wheels for moving the second tank.

9. The facility according to claim 8 , further comprising:
a first supply unit adapted to supply the thermosetting material from the first tank to the injection machine.

10. The facility according to claim 8 , further comprising:
a second supply unit adapted to supply the cross-linking material from the second tank to the injection machine.

11. The facility according to claim 8 , further comprising:
a de-gas system for degassing the thermosetting material and the cross-linking material and the injection material.

12. The facility according to claim 8 , further comprising:
a de-gas system for degassing the thermosetting material or the cross-linking material or the injection material.

13. The facility according to claim 1 , further comprising:
a control unit adapted and arranged to control other components of the facility selected from the group consisting of the injection machine, a first supply unit, a crane and a second supply unit.

14. The facility according to claim 1 , further comprising:
an energy supply unit for supplying electric energy to other components of the facility selected from the group consisting of the injection machine, a first supply unit, a second supply unit, to a crane and to a control unit.

15. The facility according to claim 1 , wherein the facility is adapted to perform a Vacuum Assisted Resin Transfer Moulding process for manufacturing the rotor blade using epoxy or polyester as the thermosetting material.

16. The facility according to claim 1 , wherein components of the facility selected from the group consisting of the injection machine, a first supply unit, a second supply unit, a crane and a control unit and the mould or a mould portion, fit into a forty-foot equivalent unit.

17. The facility according to claim 16 , wherein components of the facility selected from the group consisting of the injection machine, a first supply unit, a second supply unit, a crane, a control unit and a segmented mould, fit into a twenty-foot equivalent unit.
