Definitions

  • the invention relates to a wind turbine.
  • Modern wind turbines typically have a nacelle that is pivotally mounted on a mast that holds the essentially horizontal rotor axis of a rotor, usually with three rotor blades, that drives a generator.
  • the invention is therefore a wind power plant with a rotor with a number of rotor blades, which is rotatably mounted on a gondola, which in turn is rotatably mounted on the top of a mast, the gondola with at least one permanently installed textile escape slide is equipped, which is folded in its installed state and automatically deploys due to gravity from the nacelle along the outside of the mast downward.
  • the present invention has recognized that, despite the concerns of experts regarding the actual usability in emergency situations, escape slides represent an advantageous variant for an escape route from the nacelle of a wind turbine. Due to their small size when installed, they can easily be integrated into the design of a nacelle. rieren. In addition, their actual use is straightforward and requires no special training.
  • the present invention is based on the knowledge that, in the case of wind turbines, the reservations existing among the experts, owing to a perceived risk, that a textile escape slide hanging from the nacelle of a wind turbine to the ground - which generally means a length of the escape slide of over 100 m - could swing in an uncontrolled manner due to wind effects and could hit the mast, which could lead to serious injuries to people using the slide, are generally unjustified. While there may be wind scenarios in which a textile escape slide could actually be pressed against the mast, the risk considerations made up to now ignore the fact that, in such strong wind situations, the maintenance or other work in the nacelle of a wind turbine is neglected are already strictly prohibited for occupational health and safety reasons.
  • Textile escape slides as such are known as emergency exits from conventional buildings.
  • wind turbines which due to the typically round mast diameter generally do not offer any wind protection, are unknown in the prior art because they were considered to be too dangerous for use.
  • the rear end of the gondola is inside the gondola or on an overhanging one
  • the “rear end of the nacelle” denotes the end of the nacelle of the wind power plant that is remote from the rotor and the rotor blades.
  • the position of the trap door at the rear end of the gondola within the gondola is advantageous since the risk of being locked in by fire is greatest here.
  • the provision of an escape route at this location significantly reduces the risk of death.
  • the textile escape slide is on an overhanging platform on the top of the gondola, especially if there are enough escape routes within the gondola to reach the overhanging platform.
  • the trap door is equipped with a mechanism that automatically triggers the escape slide when the trap door is opened.
  • the release of the escape slide is accelerated because it is used instead of two or more Handles, such as opening the trap door and releasing the escape slide, only one hand, namely opening the trap door, is required.
  • the escape slide can also be provided mounted on the gondola in a mounting frame which is designed so that it can be pushed or pivoted over the edge of the top of the gondola in order to then unfold the textile escape slide.
  • Corresponding configurations - which are generally known from escape slides for high-rise buildings - have the advantage that the escape rushes are less exposed to environmental influences than e.g. an escape slide that is mounted on a fixed cantilevered platform. This applies in particular if the escape slide is provided with a cover that further protects the slide and is easy to implement in this configuration with a mounting frame.
  • the escape slide is designed in such a way that it can be fastened to attachment points at the lower end of the mast after it has been unfolded. In this way, the risk of the escape slide coming into contact with the mast of the wind turbine is further reduced. However, in order that the escape slide can be attached to these attachment points, it must be ensured that there are suitable personnel on the bottom of the mast.
  • the escape slide can be provided with inflatable stiffening elements and / or inflatable cushions in the longitudinal direction, which are automatically inflated when the textile escape slide is deployed.
  • the stiffening elements can reduce the lateral deflection of the escape chute during use, while the inflatable padding can further reduce the impact of the textile escape chute if it comes into contact with the mast.
  • the escape slide be made of fireproof fabric. This ensures the safety of the escape route in the event of a fire in the nacelle.
  • the escape slide consists of at least partially transparent or translucent tissue. Due to the considerable length of the escape slide in a wind turbine, the advantage is that people get a general feeling for what height they are. This advantage can be sufficiently achieved with a translucent fabric, even more so with a transparent fabric.

  • the wind turbine 1 comprises a rotor 2 with a plurality of rotor blades 3 (only shown in parts).
  • the rotor 3 is rotatably mounted on a nacelle 4 to drive a generator (not shown), the rotor axis being substantially horizontal.

  • the gondola 4 is equipped with a permanently installed textile escape slide 10.
  • the escape slide 10 is located at a manhole 12 under a trap door 11 within the nacelle 4, which is provided at the rear end of the nacelle 4.
  • the door 11 is usually closed and can be entered, but is shown in Figure 1 for illustration in the open state.
  • the escape slide 10 consists of transparent and fire retardant fabric and is kept in the folded state shown in Figure 1 as long as the trap door 11 is closed.
  • FIG. 2 The wind energy installation 1 from FIG. 1 with an unfolded escape slide 10 is shown in FIG. 2.
  • the escape slide 10 extends from the nacelle 4 to the bottom of the mast 5, where it has an exit Has opening 13. People who leave the gondola 4 can get into the escape slide 10 at the manhole 12 in the gondola 4 and, as is customary with textile escape slides 10, slide through the slide 10 at a limited speed until the floor is reached and the escape slide 10 over the Opening 13 can be left.
  • an inflatable stiffening element 14 which helps to keep the escape slide 10 straight in the unfolded state. Since the stiffening element 14 is arranged on the escape chute 10 towards the mast 5, it also serves as cushioning in the unlikely event that the escape chute 10 comes into contact with the mast 5.
  • the stiffening element 14 is automatically inflated by means of a pressurized gas container (not shown) as soon as the slide 10 on the nacelle 4 is unfolded. The gas used to inflate the stiffening element 14 is non-combustible.
  • FIG. 3 shows schematically a second embodiment of a wind turbine 1 according to the present invention.
  • the wind turbine 1 is constructed identically to that shown in FIGS. 1 and 2. Reference is therefore made to what has been said above for general explanations. In the fol lowing only the different design of the escape slide 10 is explained.
  • the escape slide 10 which in turn consists of translucent and fire-retardant fabric, is mounted on a receiving frame 15 on the top of the nacelle 4.
  • the receiving frame 15 In the installed state, the receiving frame 15 is in the upright position and the escape slide 10 is in the folded state.
  • the release state of the escape slide 10 is shown in Figure 4 Darge. After pivoting the receiving frame 15 into a horizontal position, the escape slide 10 unfolds due to the force of gravity from the receiving frame 15 on the gondola 4 to the bottom of the mast 5 and thus creates an additional escape route from the gondola 4.
