Embodiment Construction

[0024] In the figures, reference numeral 1 denotes a turbine arrangement comprising a first screw turbine 2 and a second screw turbine 4 . The screw turbines 2, 4 are rotatable about a first turbine axis 6 and a second turbine axis 8, respectively.

[0025] The screw turbines 2 , 4 are supported in a suspension 10 connected to a fixture 12 provided on the seabed 14 . The suspension device 10 is rotatable about a vertical axis 16 and about a horizontal axis 18 relative to the fixed member 12 .

[0026] The two screw turbines 2 , 4 , which have opposite pitches and rotate in opposite directions of rotation, are connected to each other via a transmission 20 .

[0027] Each of the screw turbines 2, 4 is connected to a respective power machine 22, which in the preferred exemplary embodiment is constituted by an electric generator. Necessary wiring is not shown.

[0028] A swivel suspension 24 is arranged in the fixed part 12 . The swivel suspension 24 is arranged to be locked t...

Abstract

A turbine arrangement (1) for extracting energy from flowing water, the turbine arrangement including a screw turbine (2, 4) with a suspension means (10), buoyancy element and bottom mount (12), and necessary transmission elements for transmitting energy to a power machine (22), and the turbine arrangement (1) including at least two parallel screw turbines (2, 4).

Description

technical field [0001] The invention relates to a turbine arrangement. More specifically, the present invention relates to a turbine arrangement for extracting energy from flowing water, comprising a screw turbine with suspension, buoyancy elements, fixings and necessary transmission elements for transferring energy to a power machine . Background technique [0002] It is well known, for example, that tidal flows contain considerable energy. However, harvesting valuable energy from tidal flows has proven to involve considerable challenges. [0003] According to the prior art, so-called tidal mills are used, in which structures similar to windmills are placed on the seabed. The blades of tidal turbines sweep over a larger area. The forces generated are also considerable and must be absorbed by the bulky and heavy tower structure. Some prior art tower structures also protrude above the sea surface, which may have a disfiguring effect and hinder navigation. Contents of t...
