Abstract

The present invention relates to a heating installation arrangement and a method of forming the heating installation arrangement for a wind turbine blade. The heating installation arrangement ( 100 ) for a wind turbine blade comprises a sleigh ( 101 ), wherein the sleigh ( 101 ) forms a platform of the heating installation arrangement ( 100 ), the sleigh further includes a recess ( 109 ), wherein the recess ( 109 ) includes one or more connection points ( 110, 112 ) for a corresponding one or more heating apparatus.

First claim

What is claimed is:

1. A heating installation arrangement for a wind turbine blade comprising:
a sleigh within the wind turbine blade, wherein the sleigh forms a platform of the heating installation arrangement; and
wherein a portion of the sleigh forms a recess within the sleigh, wherein the recess forms a lower portion of an air flow channel, wherein the air flow channel comprises an air input and an air output, wherein one or more connection points are disposed within the recess and correspond to one or more heating apparatuses also disposed within the recess and the air flow channel, wherein the one or more heating apparatuses are disposed between the air input and the air output of the air flow channel, wherein the one or more heating apparatuses comprise one or more of a heater and a fan.

2. The heating installation arrangement as claimed in claim 1 , in which one or more sections of said recess form a lower portion of ducting for channeling air flow through said heating installation arrangement.

3. The heating installation arrangement as claimed in claim 1 , further comprising:
two or more ribs, wherein the two or more ribs extend below said sleigh; and
wherein the two or more ribs form attachment points to attach said heating installation arrangement to an internal structure of said wind turbine blade.

4. The heating installation arrangement as claimed in claim 3 , further comprising:
four ribs extending below said sleigh and spaced at substantially equal distances along the sleigh.

5. The heating installation arrangement as claimed in claim 3 in which the two or more ribs further comprise an indentation on an outer edge of said rib to form a moisture channel between said rib and an internal surface of said wind turbine blade.

6. The heating installation arrangement as claimed in claim 3 , in which said ribs further comprise one or more access points to provide access to an area below said sleigh.

7. The heating installation arrangement as claimed in claim 1 , wherein one of the one or more connection points comprises a fan connection point;
wherein one of the one or more heating apparatuses comprises a fan; and
said fan connection point in said recess is shaped to substantially match an external profile of said fan installed at said fan connection point.

8. The heating installation arrangement as claimed in claim 1 wherein one of the one or more connection points comprises a heater connection point;
wherein one of the one or more heating apparatuses comprises a heater; and
said heater connection point in said recess is shaped to substantially match an external profile of said heater installed at said heater connection point.

9. The heating installation arrangement as claimed in claim 1 further comprising:
one or more upper portion sections to form ducting for channeling air flow through said heating installation arrangement; and
wherein the one or more upper portions sections are attached to said sleigh over said recess.

10. The heating installation arrangement as claimed in claim 1 further comprising:
an electrical junction box for connecting said heating apparatus to electrical control signals and electrical power.

11. The heating installation arrangement as claimed in claim 1 further comprising:
one or more lifting apparatus engagement points.

12. The heating installation arrangement as claimed in claim 1 in which said recess is a U shape; and wherein an input for air flow into said heating installation apparatus and an output for heated air flow out of said heating installation apparatus are located at one end of said sleigh.

13. The heating installation arrangement as claimed in claim 1 , in which said sleigh further comprises an input and an output wherein air flows into said heating installation arrangement via said input and air flows out of said heating installation arrangement via said output.

14. The heating installation arrangement as claimed in claim 13 further comprising flexible ducting at said input or said output to decouple said heating installation arrangement from loads, vibrations, and noise.

15. The heating installation arrangement as claimed in claim 13 , in which said input further comprises a duct to direct air flow into said heating installation arrangement.

16. The heating installation arrangement as claimed in claim 13 , in which said output further comprises a duct to direct air flow into said wind turbine blade.

17. A method of forming a heating installation arrangement comprising:
forming a sleigh for a wind turbine blade from a composite material, wherein a portion of the sleigh is formed with a recess within the sleigh, wherein the recess forms a lower portion of an air flow channel, wherein the air flow channel comprises an air input and an air output; and
forming one or more connection points within the recess for a corresponding one or more heating apparatuses disposed within said recess and the air flow channel, wherein the one or more heating apparatuses are disposed between the air input and the air output of the air flow channel, wherein the one or more heating apparatuses comprise one or more of a heater and a fan.

18. The method of forming said heating installation arrangement as claimed in claim 17 in which one or more sections of said recess form a lower portion of ducting for channeling air flow through said heating installation arrangement; and
attaching an upper portion for said ducting.

19. The method of forming said heating installation arrangement as claimed in claim 17 in which said, wherein one of the one or more connection points comprises a fan connection point; and
attaching a fan into said fan connection point in said recess.

20. The method of forming said heating installation arrangement as claimed in claim 17 , wherein one of the one or more connection points comprises a heater connection point; and
attaching a heater into said heater connection point in said recess.

21. The method of forming said heating installation arrangement as claimed in claim 17 further comprising:
forming two or more ribs, wherein said ribs extend below said sleigh; and
said two or more ribs form attachment points to attach said heating installation arrangement to an internal structure of a wind turbine blade.

22. The method of forming said heating installation arrangement as claimed in claim 21 , further comprising forming an indentation on an outer edge of said rib to form a moisture channel between said rib and an internal surface of said wind turbine blade.

23. The method of forming said heating installation arrangement as claimed in claim 17 , further comprising forming an input and an output.

24. The method of forming said heating installation arrangement as claimed in claim 23 , further comprising attaching flexible ducting to said input or said output to decouple said heating installation arrangement from loads, vibrations and noise.

25. The method of forming said heating installation arrangement as claimed in claim 23 , further comprising attaching ducting to said input and output to direct air flow into said wind turbine blade.
