Abstract

Claims (31)

1. A bulkhead for a wind turbine comprising:

at least two access openings, each opening formed in a closable manner and including a hatch flap,

wherein the wind turbine comprises:

a rotor hub; and

a rotor blade having a blade root,

wherein the bulkhead is arranged in or on the blade root or in the area between the blade root and the rotor hub.

2. The bulkhead of claim 1 , wherein at least one access opening is arranged between a center of the bulkhead and a peripheral edge of the bulkhead.

3. The bulkhead of claim 1 , wherein the at least two access openings are arranged on a peripheral edge of the bulkhead.

4. The bulkhead of claim 3 , wherein the at least two access openings are offset with respect to each other at a predetermined angle between 45° and 180°.

5. The bulkhead of claim 4 , wherein the at least two access openings are arranged in an area of a nose of the rotor blade and/or in an area of a pressure side of the rotor blade and/or in an area of a suction side of the rotor blade and/or on a rear edge of the rotor blade.

6. The bulkhead of claim 5 , wherein the bulkhead has a circular shape with a diameter greater than 2.0 m.

7. A rotor blade for a wind turbine comprising:

a blade root; and

a bulkhead having at least two access openings,

wherein the at least two access openings include closable hatches and hatch flaps,

wherein the rotor blade is operatively attached to a rotor hub of the wind turbine, and

wherein the bulkhead is arranged in or on the blade root or in the area between the blade root and the rotor hub.

8. The rotor blade of claim 7 , wherein at least one access opening is arranged between a center of the bulkhead and a peripheral edge of the bulkhead.

9. The rotor blade of claim 7 , wherein the at least two access openings are arranged on a peripheral edge of the bulkhead.

10. The rotor blade of claim 9 , wherein the at least two access openings are offset with respect to each other at a predetermined angle between 45° and 180°.

11. The rotor blade of claim 10 , wherein the at least two access openings are arranged in an area of a nose of the rotor blade and/or in an area of a pressure side of the rotor blade and/or in an area of a suction side of the rotor blade and/or on a rear edge of the rotor blade.

12. The bulkhead of claim 11 , wherein the bulkhead has a circular shape with a diameter greater than 2.0 m.

13. A wind turbine comprising:

a rotor hub;

a rotor blade having a blade root; and

a bulkhead having multiple access openings each opening formed in a closable manner and including hatch flap,

wherein the bulkhead is arranged in or on the blade root or in the area between the blade root and the rotor hub.

14. The wind turbine of claim 13 , wherein the multiple access openings are arranged between a center of the bulkhead and a peripheral edge of the bulkhead.

15. The wind turbine of claim 14 , wherein the multiple access openings are offset with respect to each other at a predetermined angle between 45° and 180°.

16. The wind turbine of claim 15 , wherein the multiple access openings are arranged in an area of a nose of the rotor blade and/or in an area of a pressure side of the rotor blade and/or in an area of a suction side of the rotor blade and/or on a rear edge of the rotor blade.

17. The wind turbine of claim 16 , wherein the bulkhead has a circular shape with a diameter greater than 2.0 m.
