Definitions

• Wind turbine unit with at least one wind turbine
• the invention relates to a wind turbine unit having at least one wind turbine (1) with a vertical or horizontal axis of rotation and with power generators (5), wherein the wind turbine unit can be mounted on a tower (2), mast or chimney.
• Such wind turbines are known.
• a wind turbine is permanently attached to the top of, for example, an industrial chimney.
• the wind turbine is exposed to more wind and generates more energy than when placed near the ground.
• the disadvantage is the need to design the wind turbine so strong and robust that even the strongest wind speeds and storms the
• a relevant prior art is also known from the documents DE 10 2007 015 301 AI, DE 20 2007 013 492 Ul, DE 10 2009 035 997 AI and DE 10 2008 048 000 AI.
• the tower or mast itself is changed in length, so that the wind turbine is adjustable in height.
• Object of the invention The advantages of an arrangement of the wind turbine at a very high altitude should be maintained without, first, the wind turbine built so robust must be able to withstand the high wind speeds occurring at high altitude in storms, and secondly without additional costs for the construction and maintenance of a tall tower, mast, chimney or the like.
• This object is achieved in a wind turbine unit of the type mentioned according to the invention that the wind turbine unit on the already existing tower (2), mast or chimney up and down is movable. The tower itself remains unchanged in its length.
• towers are all tower-like structures such as masts, industrial fireplaces, lattice towers such as radio transmitter masts, construction cranes, offshore rigs, tall tanks, silos, tower towers, skyscrapers, skyscrapers (there also side attach), lamp posts and columns and other supporting structures such as bridges.
• the wind turbine according to the invention still reaps much wind energy even when the wind near the ground is already quite weak, since the wind is still strong at high altitudes, for example, towers or industrial chimneys with a height of 100 meters in such cases.
• the amount of C0 2 which can be saved due to the fact that the wind at only twice the wind speed, z. B. 50 m / s, already an eightfold energy as simple wind speed, z. B. 25 m / s, is a significant advantage over other wind turbines that do not have this flexibility.
• the static of a tower of about 100 meters is designed for wind speeds up to about 50 m / s. Nevertheless, the wind turbine only needs to be designed for wind speeds up to a moderate limit, for example up to 25 m / s. If the wind is too strong at the top of the tower, the wind turbine moves down the tower into areas where the wind speed has fallen below the specified limit, for example to 25 m / s, where it can continue to operate and harvest energy. Therefore, only the statics of the tower must be designed for higher wind speeds, the wind turbine itself but only to significantly lower wind speeds. An otherwise required massive construction, z. B. concrete with strong Steel reinforcement or a steel mast with high steel consumption is not necessary according to the invention. An important advantage is therefore the saving of resources such as steel and concrete.
• the numerical values mentioned are just one example. Depending on the geographical location and the prevailing wind conditions, the optimal there are just one example. Depending on the geographical location and the prevailing wind conditions, the optimal there are just one example. Depending on the geographical location and the prevailing wind
• Profitability limit are calculated. Especially near the coast it will be worthwhile.
• the tower, mast or chimney is hydraulically repositioned from the vertical position to a horizontal or oblique position, especially when a storm rises.
• the wind turbine can also be used in storm-prone regions.
• the foundation does not need to be designed as strong as one
• Wind turbine without relocation.
• mast or chimney is transferred to a horizontal position during storms and thus brought to safety, the forces acting on the foundation are no longer distributed at random, but over a relatively large area.
• the tower is portable, can be brought in danger to a safe position and calm in a place with stronger wind.
