Embodiment Construction

[0019] Figures 1, 2a, 2b show a device for harvesting energy from tidal energy. The apparatus comprises a cylindrical pontoon 1 having depending from its underside two counter-rotating rotors 2 driven by rotor blades 3 which pass tidal water (not shown) flowing over them. ) to rotate around the rotor central body 4.

[0020] More specifically, the cylindrical floating boat 1 includes a hollow main body composed of a multi-cavity structure made of steel plates (or reinforced concrete), and its streamlined front portion 12 and inclined rear portion 13 are combined to form a whole. The cylindrical pontoon 1 may include components such as transformers and possibly power conversion equipment (not shown). The interior of the body 1 can be accessed through a watertight hatch (not shown).

[0021] A hydraulically supported keel section 8 is attached to the cylindrical pontoon 1, providing, if required, variable longitudinal positioning of the lower rotor arm 6 which supports the sub...

Abstract

The present invention relates to a power generating apparatus suitable for use in extracting energy from the movement of water, particularly tidal movement. The apparatus comprises an elongate, generally circular in cross section, buoyancy vessel (1), having depending from its underside on a mounting means, rotatable rotor blades (2). The rotor blades are connected to a power generating means whereby in use of the apparatus movement of water across the rotor blades, drives them so as to generate power in the power generating means.

Description

technical field [0001] The present invention relates to a power plant for obtaining energy from the motion of water, especially tidal motion or other water currents such as rivers. In particular the invention relates to a flotation device. Background technique [0002] Although in recent years there has been a trend towards so-called renewable energy sources such as wind and wave energy, the visual impact of wind turbines is severe and of course also dependent on windy weather. Wave power plants have proven to be difficult to implement effectively for a number of reasons, not the least of which is the enormous cost of equipment to withstand the enormous wave energy generated during storms. [0003] Tidal energy, on the other hand, is based on a guaranteed source of energy, namely tidal motion. Over the years, a large number of tidal power generation devices have been proposed including, for example, International Patent Publication No. WO88 / 04632, US 3986787, DE 2648318 an...
