Description
Das ProblemThe problem
Für die Nutzung der Windenergie werden zur Stromerzeugung in aller Regel hohe Windräder sowohl an Land, als auch „off shore“ errichtet und eingesetzt. Diese Großwindanlagen fallen in der freien Landschaft aber sofort in Auge, ob in flacher oder in bergiger Gegend. Dadurch kommt es zu einer Beeinträchtigung des Landschaftsbildes, außerdem fällt die Nutzung dieser Anlagen in dicht besiedelten Gebieten oder urbanem Umfeld durch die damit verbundenen Nebenwirlungen, wie Geräusche und Schattenwurf aus. Nicht zu vergessen sind dabei auch die ökologischen Nachteile des Vogelschlages und Wirkung auf geschützte Arten wie Fledermäuse. Ein weiterer Nachteil von Windrädern ist, dass der Wind zwar genutzt wird, aber alle anderen Wirkungen des Wetters auf die Lebensdauer und die Wartung eneromen Einfluss haben, was die Energiebilanz negativ belastet.For the use of wind energy, high wind turbines are usually built and used both on land and “offshore” to generate electricity. These large wind turbines immediately catch the eye in the open landscape, whether in flat or mountainous areas. This leads to an impairment of the landscape, and the use of these systems in densely populated areas or urban surroundings is not possible due to the associated side effects, such as noises and shadows. Not to be forgotten are the ecological disadvantages of bird strikes and the effects it has on protected species such as bats. Another disadvantage of wind turbines is that the wind is used, but all other effects of the weather on the service life and maintenance have an energy effect, which has a negative impact on the energy balance.
Die LösungThe solution
Statt der sich vertikal drehenden Freiwinddrehflügel kommen horizontal drehende teilgekapselte Flachwindturbinen zum Einsatz, deren Durchmesser und Bauhöhe vergleichsweise klein ist, vor allem was deren Höhe betrifft.Instead of the vertically rotating free wind blades, horizontally rotating, partially encapsulated flat wind turbines are used, the diameter and height of which are comparatively small, especially in terms of their height.
Als Basis kommen alle hohe dem Wind ausgesetzte Stellen infrage und das auch im urbanen Bereich, wie etwa auf Gebäuden, Industrieanlagen etwa auf Tanks, Silos oder Gasometern, aber auch in der Landschaft, etwa auf Ruinen in Berglage, oder auch direkt auf Bergkuppen, was sogar über der Baumhöhe noch möglich ist und schon auf mittlere Entfernung nicht mehr auffällt. Auch Bergbahnstationen oder Gipfelhäuser kommen daher sogar infrage.All high places exposed to the wind come into question as a basis, including in urban areas, such as on buildings, industrial plants, for example on tanks, silos or gasometers, but also in the landscape, for example on ruins in a mountain location, or directly on mountain tops, whatever is still possible even above tree height and is no longer noticeable at a medium distance. Mountain railway stations or summit houses are therefore even an option.
Die obere Abdeckung der Horizontal-Windturbine, im weiteren „HoWiT“ genannt, erlaubt dazu eine vielfältige Verwendung, sei es als Solarpark, Heliport oder Aussichtsplattform.The upper cover of the horizontal wind turbine, hereinafter referred to as "HoWiT", allows a wide range of uses, be it as a solar park, heliport or viewing platform.
Außerdem ist die Mechanik durch die Abdeckung Teileinhausung auf der Luv-Seite sehr wind- und Wetter geschützt und damit sehr langlebig und wartungsfreundlich. Der ökologische und energiewirtschaftliche Effekt widersprechen sich nicht, sondern ergänzen sich.In addition, the mechanism is very wind and weather protected by the partial housing cover on the windward side and is therefore very durable and easy to maintain. The ecological and energy-economical effects do not contradict each other, but complement each other.
Die Beschreibung der ErfindungThe description of the invention
Auf einem dem direkten Windanstrom ausgesetzten Niveau (Hochhaus/Tank/Anhöhe) dreht sich zwischen der Ober-und Unterplatte ein an senkrecht stehender Achse horizontal ein mehrflügliche Rotor, der sich im Beispiel sich nach rechts oder links drehen kann.At a level exposed to the direct wind current (high-rise / tank / hill) a multi-blade rotor rotates horizontally between the upper and lower plate on a vertical axis, which in the example can rotate to the right or left.
Damit die Windkraft sich bei freiem Andruck nicht aufhebt, werden die gegen den Wind rücklaufenden Flügeln abgedeckt, sodass der Wind nur auf die ablaufenden Flügel des Rotors wirkt. Die Abdeckung wird sensorisch, abhängig von der Windrichtung, gesteuert, sodass sich die rücklaufenden Flügel ohne den Gegendruck des Windes wieder in dessen Anströmung drehen. So that the wind power does not cancel out when the pressure is free, the blades moving back against the wind are covered so that the wind only acts on the moving blades of the rotor. The cover is controlled by sensors, depending on the wind direction, so that the retracting blades turn back into the flow without the counterpressure of the wind.
Bei zu starkem Winddruck kann die Abdeckung so gestellt werden, dass der Wind die Rotation des Rotors stoppt.If the wind pressure is too strong, the cover can be set so that the wind stops the rotor from rotating.
Die aero-dynamische Energie des Rotors lässt sich analog der hydro-dynamischen Turbine mit Stromgeneratoren koppeln. Die obere Abdeckung (Deckel) lässt sich zudem vielfach nutzen, während die untere Abdeckung unter bestimmten günstigen Umständen (Flachdach/Tank) entfallen kann.The aerodynamic energy of the rotor can be coupled with electricity generators in the same way as the hydrodynamic turbine. The upper cover (lid) can also be used in many ways, while the lower cover can be omitted under certain favorable circumstances (flat roof / tank).
Geräusche der HoWitT gehen im urbanen Bereich ohnehin hohen Pegel des Windes oder des Verkehrs unter, auch kommt es zu keinem Schattenwurf und die Gefahr des Vogelschlages ist gering. Die vergleichsweise geringe Eigenbauhöhe zum Durchmesser der HoWiT Turbine spricht für deren Einsatz.Noises from HoWitT in urban areas are already drowned out by high levels of wind or traffic, there are also no shadows and the risk of bird strikes is low. The comparatively low self-construction height to the diameter of the HoWiT turbine speaks for its use.
