DECENTRALISED WIND TURBINE

I have invented a decentralised, cost-effective and powerful wind power plant for urban areas.

The system is a wind turbine that can be mounted on a vertical structure. For example, on the roof of a house or a street lamp.

The system is rotatably mounted on a pole so that it is always orientated in the direction of the wind. Due to the special location of the turbine and its design (see advantages of the "TORQUE-e1" series), the wind can be concentrated at the rotors, which significantly increases the electricity yield. Due to the higher energy density of the wind, electricity can also be generated profitably in cities. The rotating rotors are virtually invisible and quiet thanks to the rotor casing.

The wind turbine shown at the iENA 2024. The picture shows an ‘A-sample’. The generator unit has been dismantled and

there is no turbine installed on one side to demonstrate the modular turbine unit.

Description

The invention relates to a wind turbine. In particular, the invention relates to a wind turbine for urban areas.

The wind turbine comprises a rotor and a generator. The rotor is adapted to be rotated by wind in an environment and the generator is adapted to provide electrical energy based on the rotation. An optional control device can control the energy provided, for example to influence a rotational speed of the rotor or to process the electrical energy so that it can be fed into a power supply network.

The present wind turbine can have a simple and compact design. The rotors can be mounted at the same vertical height. Due to the arrangement of the rotors, the wind turbine can be well balanced with respect to horizontal loading by wind and/or with respect to vertical loading by gravity. The wind turbine can be used advantageously in an urban area, for example in a city, a residential area or near a sports or leisure facility. This can make a valuable contribution to the decentralised and sustainable provision of electrical energy. The wind turbine can have only a few moving parts and be easy to maintain. Standard parts can be used for its construction, which can be inexpensive and also available in large quantities.

Furthermore, according to the invention, the respective casing is incompletely closed in the region of one end of the V-shaped section in order to allow wind into the region of the respective rotor. Thus, a vertical gap or slit can exist between the V-shaped section and the end, through which wind can enter the area of the rotor.

The shroud can advantageously act as a funnel to direct more wind to the rotor, see product TORQUE-e1. Optionally, one end of the guiding element can be supported relative to the V-shaped section, for example by means of a strut or a lattice, in order to give the shroud additional stability.

According to the invention, the respective sheathing has a cut-out for the exit of wind. The cut-out is preferably essentially opposite an inlet opening for wind.
