Definitions
- the present invention relates to a method of mounting elements in a wind turbine tower.
- wind turbine towers carry the nacelle and the rotor of a wind turbine in order to allow for the desired rotation of the rotor and to raise the rotor into a position as far as possible from the ground as wind speeds typically increase with the distance to the ground.
- a wind turbine tower may be constructed according to several different principles, e.g. as tubular steel towers, lattice towers, or even concrete towers.
- the steel towers typically comprise an interior with platforms, ladders, illumination means, power cables, lifts, etc.
- the components are welded to the inner surface of the steel tower section, or directly attached to the fittings, which have been welded and/or bolted to the tower.
- the invention relates to a method of mounting elements in a wind turbine tower ( 10 , 11 , 12 , 13 , 14 ), whereby said elements are partly or completely attached to the wind turbine tower ( 10 , 11 , 12 , 13 , 14 ) by means of a magnetic attraction forces.
- the wind turbine suspension units may be attached to the wind turbine tower, preferably completely or partly to the inner wall by means of magnetic attraction forces, thereby preventing structure-weakening attachments to the tower or part of the tower.
- a wind turbine tower may comprise of a number of tower sections.
- Permanent magnetic materials may be relatively stable and the necessary attraction forces may be maintained over a relatively long period.
- a suspension unit according to the invention may advantageously be provided with permanent magnets.
- a typical application of a suspension unit may be regarded as a “hybrid suspension” in the sense that the magnetic forces are primarily applied in order to handle the transverse suspension forces, whereas a mechanical suspension forces primarily deal with vertical suspension, i.e. typically gravity induced force on the suspended structure.
- suspension units may be applied for suspension based on magnetic attraction forces only if the magnetic attraction forces available are sufficient for the desired attachment.
- wind turbine tower components may be mechanically suspended between the end point(s) of the turbine tower or wind turbine tower sections, thereby avoiding weakening of the wind turbine tower, which is typically caused by welding.
- the magnetic attachment means may then form a supplement to the mechanical suspension in areas in which no mechanical attachment is desired or possible.
