INFLATABLE COMPONENT FOR SERVICE OR INSTALLATION OF A WIND TURBINE MODULE
Provided is an inflatable component usable during service and/or in-stallation of a wind turbine module, including an inflation structure with an air tight shell and a sealable package in the inflation structure for ingress or discharge of air into or from the air tight shell for inflating or deflating struc-ture. The inflation structure is dimensioned to provide a thermal and/or physical barrier in respect of external fluids and/or physical objects or particles acting upon the infla-tion structure in case the inflation structure is inflated and inserted in a hollow section of the wind turbine module. Further provided is a wind tur-bine arrangement including such an inflatable component and also to a servicing or installation method of a wind turbine module by using the inflatable component.
1 . An inflatable component usable during service and/or installation of a wind turbine module,
comprising
an inflation structure with an air tight shell and
a sealable passage in the inflation structure for ingress or discharge of air into or from the air tight shell for inflating or deflating the inflation structure,
wherein
the inflation structure is dimensioned to provide a thermal and/or physical barrier in respect of external fluids and/or physical objects or particles acting upon the inflation structure in case the inflation structure is inflated and inserted in a hollow section of the wind turbine module.
2 . The inflatable component according to claim 1 , wherein
the air tight shell comprises an air tight inner shell and an outer shell surrounding the inner shell, the outer shell being of a material to protect against puncture of the inner shell.
3 . The inflatable component according to claim 1 , wherein
the inflatable component is sized and shaped to fit the hollow section of the wind turbine module such that, in case the inflation structure is inflated and inserted in a hollow section of the wind turbine module, a first surface structure of the inflatable component and a second surface structure of the hollow section of the wind turbine module are in fluid tight contact to limit or block a fluid leakage in between.
4 . The inflatable component according to claim 1 ,
wherein
the air tight shell is built of several air compartments.
5 . The inflatable component according to claim 1 ,
wherein
the inflatable component further comprises a plurality of securing members via which the inflatable component is positioned and held in place in case the inflation structure is inflated and inserted in a hollow section of the wind turbine module.
6 . The inflatable component according to claim 1 ,
wherein
the sealable package in the inflation structure is arranged as one or several valves.
7 . The inflatable component according to claim 1 ,
wherein
the inflatable component is a portable component in case the inflation structure is deflated.
8 . The inflatable component according to claim 1 ,
wherein
the inflatable component is a configured to provide a working platform for persons in case the inflation structure is inflated, inserted in a hollow section of the wind turbine module, and arranged horizontally.
9 . The inflatable component according to claim 1 ,
wherein
the inflatable component is built substantially from a deformable material.
10 . A wind turbine arrangement,
comprising
a wind turbine module, wherein the wind turbine module is a wind turbine blade, a wind turbine tower, a wind turbine hub, a wind turbine nacelle, and
the inflatable component according to claim 1 ,
wherein the inflatable component is positioned and inflated inside a hollow section of the wind turbine module for service and/or installation of a wind turbine module. cm 11 . A servicing or installation method of a wind turbine module,
comprising the steps of:
(a) inserting an inflatable component into a hollow section of a wind turbine module, the inflatable component comprising an inflation structure with an air tight shell and a sealable passage in the inflation structure for ingress or discharge of air into or from the air tight shell for inflating or deflating the inflation structure; and
(b) inflating the inflatable structure such that it forms a thermal and/or physical barrier in respect of external fluids and/or physical objects or particles acting upon the inflation structure.
12 . The servicing or installation method according to claim 11 ,
comprising, before step (a), the further steps of:
(a1) decoupling the wind turbine module from a wind turbine installation; and
(a2) orienting the wind turbine module in horizontal orientation;
wherein step (a) is performed while orienting the inflatable component vertically inside the hollow section, such that the inflatable component provides the barrier for a horizontal movement of the external fluid or of the external physical objects or particles.
13 . The servicing or installation method according to claim 11 ,
comprising, before step (a), the further steps of:
(a1) decoupling the wind turbine module from a wind turbine installation; and
(a2) orienting the wind turbine module in vertical orientation;
wherein step (a) is performed while orienting the inflatable component horizontally inside the hollow section, such that the inflatable component provides the barrier for a vertical movement of the external fluid or of the external physical objects or particles.
14 . The servicing or installation method according to claim 11 ,
wherein
during step (a) the inflatable component is connected by strings and/or wires to the wind turbine module.
15 . The servicing or installation method according to claim 11 ,
comprising the further step of:
(c) applying heat inside wind turbine module.
