Definitions
- Wind turbines with various types of rotor blades have been known for a long time. It is also known that in certain situations the wind energy installation must be equipped with a hazard fire in order to point out to the air traffic in the area of the wind energy installation in good time that the wind energy installation exists. For the aforementioned purpose, it is also known to provide the rotor blades with mostly red warning coatings, so that the collision of an aircraft, in particular a military aircraft, with a wind energy installation or its rotor can be avoided.
- incandescent lamps or other lamps have a limited shelf life and the costs for replacing used lamps are out of proportion to the benefits.
- the cost of replacing lamps on the rotor blade tip can amount to several DM 1,000, because not only does the wind turbine have to be stopped, but also the service personnel using a crane device from the tower of the wind turbine or from the floor in front of the wind turbine to the rotor tip must be brought up.
- the object of the invention is to avoid the aforementioned disadvantages and to provide a more reliable than previously proposed illumination of the rotor blade tips, wherein any damage that occurs can no longer be eliminated as expensively as previously, but rather extremely quickly.
- the invention is based on the idea that the entire illuminant from the tip area (rotor blade tip) of the rotor blades into the area near the hub, e.g. B. to move the hub of the rotor itself. If a lamp fails, the service can replace it very easily and very easily.
- the illuminants i.e. a light generating device such. B. a laser or a light-emitting diode or a large number of these
- the light generated is fed into a glass fiber cable (light waveguide, light guide), which in turn is laid in the tip area of the rotor blade and there at the Surface of the rotor blade is arranged so that the light can exit easily,
- the invention also proposes to use the light guides to carry out possible load measurements on the rotor blade itself.
- a value for the quality can also be assumed from the quotient of the quantity of light entered to the quantity of light emerging, the quality being in the optimal case one, if the quantity of light fed into the light guide corresponds to the intensity (lumens) of the quantity of light at the exit end of the light guide.
- the quality of light guides depends not only on the material of the light guide or the type of light introduced, but also on the laying of the light guide. If, for example, the light guide is laid along a straight line, the quality is usually greater than if the light guide is laid in different serpentines or arches or other geometries with radii of curvature.
- Movement of the light guide transversely to its direction of extension also means that the continuation of the light inside the light guide is partially restricted, which leads to a decrease in the quality as a whole.
- This - last-mentioned - effect can also be used according to the invention in a rotor blade of a wind energy plant to optically / electrically measure the deflection of the rotor blade, in that a light guide quasi as a loop, starting from the rotor blade hub via a specific guide in the rotor blade over the rotor blade tip and back to the hub.
- a corresponding detector is then arranged at the exiting end of the light guide, which measures the intensity of the exiting light, and this amount of light exiting is continuously set in relation to the amount of light entering the light guide via a corresponding processing device (processor).
- the load on a rotor blade can thus be determined not only integrally on the hub, rotor blade root, but also in individual points, in particular also in the blade tip area, and a possible overexpansion of the rotor blade tip due to a gust or another Event can be determined very quickly, which can also be used at the same time to possibly stop the wind turbine or to adjust the rotor blade angle (pitch) in order to rule out the undesirable case of overstretching, because such overload cases regularly shorten the life of the rotor blades considerably and thus lead the entire wind turbine.
- the light guides can be guided over a wide variety of geometries in the rotor blade itself or below the top layer of the rotor blade or on the rotor blade. Not only is there a direct return and return line from the rotor blade root to the rotor blade tip on one side or on different sides of the rotor blade, but also the spiral wrapping of the entire rotor blade from the rotor blade root to the rotor blade tip and back, or different bundles can also be used of optical fibers over the most varied geometrical courses of the rotor blade (or in the rotor blade itself).
- Rotor blade has taken place or is taking place.
- this electrical signal can also be fed directly to a remote monitoring point of the wind power installation and evaluated there accordingly and used for a very rapid intervention in the installation if automatic adjusting devices are not already provided, which automatically undertake a system control or change when the quality falls below a certain level, which relieves the rotor blades.
- tip lighting When laying the optical fibers as rotor blade tip lighting (tip lighting), it may also be suitable that the tip lighting is not switched on over the entire circumference of the rotor, but only when the respective rotor blade is in an area between the nine o'clock - And three o'clock position (the rotor blade rotates clockwise) or preferably only in the area between the ten o'clock and two o'clock position.
- FIG. 1 shows a first exemplary embodiment of a rotor blade according to the invention
- FIG. 1 shows a rotor blade 10 with an optical waveguide 14 laid thereon (or therein), which is laid in a meandering manner in the region of the rotor blade tip 15.
- a light diode 16 is arranged at one connection of the optical waveguide 14 and a corresponding light reception diode 18 is arranged at the other connection. The light diode is used to feed light into the optical waveguide and the receiving diode 18 receives the light which has passed through the light guide.
- a measure of the deflection of the rotor blade can also be determined by measuring the amount of light (light modulation measurement) in the receiving unit 18 (or light modulation measurement), since the quality when the blade is deflected is below the quality in the reference state. If certain overstretching of a rotor blade is undesirable, that is to say the quality drops below a predetermined value, this can also be monitored by means of the invention and, if necessary, the measured data can also be used to shut down the entire wind turbine for its own protection.
- the above-described alternative according to the invention also has the advantage that if there is a hairline crack in the rotor blade of the wind power installation, the hairline crack essentially running transversely to the light guide, the light guide is torn off very quickly, so that the entire light transmission is then not only disturbed, but also collapses can.
- This light guide can be torn off because the light guides are regularly designed to be extremely porous in terms of their length and are only slightly elastic. If the light transmission through the light guide is now seriously disturbed by a hairline crack, the entire system can be stopped and the rotor blade can be examined very early for possible hairline cracks.
- the device for further processing the measured light is not shown.
- These can be conventional devices that generate an electrical signal from the measured quantity of light and the corresponding electrical signal is then further processed in a processor or another processing device in such a way that the light quantity value of the received light is determined, which then possibly also in relation to the amount of light that has entered the light guide.
- the value for the quality (amount of light emitted / amount of light received) can be derived directly from this difference value. It is advisable to provide a table for certain grades in a corresponding memory, if these are exceeded or undershot, the desired measures can then be taken in the wind energy installation, for example the shutdown of the installation.
- FIG. 2 shows a bundle of optical fibers which are laid from the hub of the rotor blade (rotor blade root) to the rotor blade tip (tip).
- the hub area light is fed into the optical fiber by means of a lamp 14 and in the tip area the light emerges from the light wave divert so that the tip area glows well at least at night and air traffic is made aware of the wind turbine.
- the lamp 14 can also represent a light emitting diode.
- the activation of the lights 14 and 16 can be made dependent on the respective time of day, darkness or the respective position of an individual rotor blade, e.g. Turn on the lights when a rotor blade is in a 10 a.m. to 12 a.m. / 2 p.m. position.
- This measure has the advantage that, on the one hand, the illuminants are protected and, in addition, the lighting only takes place in a rotor blade position where the rotor blade is still visible. In addition, when the lamps are switched on, the disturbance for the environment around the wind power plant is kept as low as possible.
- the control device for controlling the lamps is preferably coupled to the wind power plant controller so that the lamps can be switched on in a position dependent on the rotor blade.
