Description

Field of the Invention

The present invention relates to the field of rescue training equipments, in particular to the use of a mobile rescue training equipment for a rescue training for wind turbines.

Art Background

With the increasing number of wind turbines used for generating of electric power it is necessary to train service people in handling rescue situations in connection with emergencies in wind turbines. This training is normally done by hiring a wind turbine and shutting it down for a day or two and then simulating an emergency situation happening somewhere in the wind turbine. This is though often very difficult and expensive as an existing wind turbine has to be hired and shut down during the training.
Document GB 729 125 A discloses a mobile equipment with a structure comprising a platform and all the features beside the two ladders of the equipment used for the rescue training in claim 1.

Detailed Description

The illustration in the drawings is schematic. It is noted that in different figures, similar or identical elements are provided with the similar or identical reference signs.
In the following some examples for exemplary height rescue safety trainings equipments used will be described in more detail.
Such equipments may be arranged in permanent training centers or may be detachably mounted on different sites which may then be called a training center as well. The trainings centers may have four different trainings facilities.
The purpose of such trainings facilities may be to enable "real life" training for height rescue, so that the practipitants is covered with all the rescue possibilities in wind power turbines. The training facilities should be close to real life locations, so that the participants can combine the training, with all the zones in wind power turbines using the specific rescue kits for example. That is, a mobile rescue training equipment may be mounted close to a "real" wind power turbine.
Some goals of such rescue kits may be:

Enabling of development or evolution of the training center by adapting the mobile training equipments, so that the education in height rescue training always is as real as possible.
Each training center may include several different training zones simulating different portions of a wind turbine
Each training center may deliver height rescue safety training on a basic rescue level, e.g. zone 1, and an advanced rescue level, e.g. zone 2 - 6, by using a dedicated rescue kit.
Each training center may have the following training facilities, to cover all the training in all zones 1 - 6 in wind power turbines.

In detail the six zones may correspond to the nacelle (zone 1), in particular to the zone under a gearbox of the nacelle, to the yaw (zone 2), to the hub (zone 3), to the bottom of the access tower (zone 4), to a cellar of the access tower (zone 5), and to the hollow part inside a rotor blade (zone 6).
In particular, rescue education may be performed in or on a simulated nacelle moveably placed on ground. Some specific rescue events, which may be classified as basic rescue operations, to be trained may be evacuation of one or two persons using the hatch of the nacelle. Some more advanced rescue events may include rescue training from the yaw, from the hub, rescue from under the gearbox, moving casualties in the nacelle, rescue casualties hanging outside of the nacelle in their personal protection equipment (PPE), rescue and evacuation through evacuation hatch on spine board, and rescue and evacuation through evacuation hatch in marine stretcher. A nacelle placed on the ground may be a suitable way to simulate or train real corresponding rescue situations.
Now a first exemplary height rescue safety training equipment will be described in more detail with respect to Fig. 1. In particular, Fig. 1 shows two side views and one perspective view of a rescue safety training equipment 100. The mock-up structure comprises a ground or base plate 101, on which a vertical tower structure 102, e.g. a frame structure, may be mounted in a detachable way. The vertical structure may as well include some frame structures 104 which are arranged in an angled form in order to support the training equipment 100. For example the frame structures 104 may be arranged on four corners or sides of the training equipment in order to provide an improved stability. On top of the vertical structure or vertical tower structure 102 a platform 103 is detachably mounted having a manhole 105 through which the platform may be entered. The platform 103 may comprise a railing 106. The training equipment further comprises two or more ladders 107 which are detachably fixed to the vertical structure and to the ground plate so that the platform can be entered by a person. Additionally a derrick or cantilever 108 may be arranged on the platform which may be used as a mock up structure for simulating rescue situations including roping. Additionally, some dimensions are stated in Fig. 1. In particular, the height from the ground plate 101 to the platform 103 may be about 10,050 mm, the height from the ground to the top of the railing may be about 11,674 mm, while the height from the ground plate to the top of the derrick may be about 12,295 mm. Additionally, some ropes may be fixed to the training equipment.
Fig. 2 schematically shows another height rescue safety training equipment 200 or setup comprising ladders and at least one wire. In particular, the training equipment comprises a base plate 201, a vertical frame structure or vertical tower structure 202 arranged on the base plate 201 having a beam or cantilever 208 on the upper end so that a wire 209 can be fixed to the frame structure by fixing it to the cantilever. For stability reasons an angled frame structure 204 may be fixed to the vertical frame structure having an angle between 20 and 80°, in particular 60°, with respect to the base plate. Furthermore, the equipment 200 comprises a ladder 207 is mounted to the vertical frame structure 202. An additional platform 210 may be mounted to the vertical frame structure so that it projects from the vertical frame structure 202 in an angle about 90°. The additional platform may have a length of about 400 mm.
It should be stressed that all described and additional components of the training equipments 100 or 200 are fixed to each other in a detachable way or manner, i.e. in a way that allows to demount the training equipment for transport.
Fig. 3 shows schematically a front view of the equipment 200 of Fig. 2 and including some information concerning the respective dimensions. In particular, Fig. 3 shows the base plate 201, which includes some base legs 312 which may have a height of about 70 mm.
