Definitions

  • the present invention relates to a heli-hoist platform for a wind turbines.
  • a wind turbine contains one or more Rotor blades mounted to a hub.
  • the hub is connected to a nacelle and the nacelle is mounted on a tower.
  • the wind turbine converts the energy of moving air to a different form of energy, mainly electric power.
  • the rotor blades are formed in a way that they can transform the energy of the moving air into a rotation of the hub.
  • the rotation of the hub is then transferred via a shaft through a gear to a generator. It is also possible, that the wind turbine is gearless and the rotation of the rotor blades and hub is directly transferred to the generator via a shaft.
  • the generator then generates electrical energy.
  • Wind turbines are erected onshore and offshore. Offshore wind turbines combine certain advantages, usually there is a higher wind speed in hub height, and also the turbines do not annoy people in a so high degree as onshore.
  • Wind turbines erected offshore have a high utilization and contain a lot of moving parts that are under high load. So there is a high need for a regular maintenance for offshore wind turbines. For service a service crew has to visit the wind turbine, usually the crew brings tools and spare parts.
  • An offshore wind turbine can be reached by ship, but the wave conditions might make it difficult, dangerous or impossible to approach the wind turbine and allow the service crew to enter the wind turbine. If the weather conditions do not allow entering the wind turbine for service or repair, this leads to a loss of production of electrical energy. A bad weather situation can occur often and last for a long time, so this might lead to situations where the wind turbine is out of order for a long time.
  • a heli-hoist platform allows service crew, that are air lifted, access to the wind turbine.
  • a heli-hoist platform is attached on top of the nacelle of a wind turbine.
  • This conventional heli-hoist platform contains a floor and a railing and is build as a structure that is attached to the nacelle. This leads to a lot of additional parts that are used for building the structure, additional weight, installation time to attach the structure to the nacelle, and this leads to high costs for the heli-hoist platform.
  • This invention provides a heli-hoist platform that is an integral part of the nacelle. Therefore fewer parts are needed, which saves not only installation time and weight but is also easier to install and saves costs for the manufacturing of the heli-hoist platform.
  • the present invention enclosed an integrated heli-hoist platform for a nacelle of a wind turbine.
  • the heli-hoist platform does not need an additional platform that is attached to/mounted on top of the nacelle.
  • an heli-hoist platform for a nacelle of a wind turbine charactered in that: platform floor, which is also the roof of the nacelle and is an integral part of the nacelle; railings, which are attached to the platform floor, in order to define the borders of the heli-hoist platform and to avoid that parts slide off the heli-hoist platform or miss the heli-hoist platform while being lowered to the heli-hoist platform.
  • the platform floor is covered with a non-slip surface to prevent accidents.
  • the heli-hoist platform includes an entrance through the platform floor to allow service crew to enter the wind turbine from the heli-hoist platform.
  • the platform floor is equipped with an additional support inside the nacelle to be capable of bearing more weight.
  • the platform floor includes several integrated fastening points, for attaching the railings to the platform floor.
  • the several integrated fastening points are attached to the platform floor by bolts or screws.
  • the several integrated fastening points are integrated in the platform floor, fitting to attach the feet of the railings to the platform floor.
  • the nacelle includes a stronger integral support with more support bars in the area of the heli-hoist platform.
  • FIG. 1 is a schematically top-view diagram illustrating an embodiment of the invention.
  • FIG. 2 is a schematically side view diagram illustrating the embodiment in FIG. 1 .
  • FIG. 3 is a schematically exploded diagram illustrating the attachment of the elements.
  • the present invention relates in general to an integrated heli-hoist platform for a wind turbines.
  • FIG. 1 One embodiment of the invention is schematically illustrated in FIG. 1 .
  • the inventive heli-hoist platform is not an additional platform that is attached to/mounted on top of the nacelle.
  • the inventive platform is an integral part of the nacelle, and the roof 1 of the nacelle is at the same time the floor of the heli-hoist platform.
  • a railing 2 is attached to the roof 1 .
  • the roof 1 of the nacelle is covered with a non-slip surface all over the heli-hoist area to prevent accidents.
  • the roof 1 of the nacelle is equipped with an additional support 3 inside the nacelle to be capable of bearing more weight.
  • FIG. 3 there are several integrated fastening points 6 on the roof 1 , for attaching the railing 2 to the roof 1 of the nacelle.
  • the several integrated fastening points 6 are attached to the roof 1 by bolts or screws or are integrated in the roof 1 , fitting to attach the “feet” of the railing 2 to the roof 1 of the nacelle, fixed or detachable.
  • the nacelle has a stronger integral support with more support bars in the area of the heli-hoist platform.
  • An integrated heli-hoist platform having above construction is easier to install, less material needed, less parts needed, less weight of the nacelle.
