Embodiment Construction

[0044] figure 1 Shown is a wave energy generating device according to the invention. The device comprises a central floating body 1 in the form of an elongated cylinder, preferably manufactured from a plastic pipe, for example polyethylene or a composite pipe with a plastic matrix containing reinforcing fibres. An annular buoyant body 2 is arranged around the central body and acts as a wave energy generating element. The annular float 2 can be made of the same material as the central body and mounted on the central float 1 so that it can slide, for example, by slippers or, as shown, by rollers 3 . A plurality of rods 4, 5, for example two rods as shown, are fixed to the annular body 2 and extend to respective wheels 6 (only one shown in the figure), which are connected by shafts 7 to the generator on the central body 8. Said rods 4, 5 preferably pass through respective lugs 9 on the central body 1 as shown, thereby ensuring that the rods 4, 5 can only move axially. The rod...

Abstract

Apparatus for generation of wave power comprising a first longitudinal floatation body (1) which is floating in a substantially vertical position in a body of water. The device also comprises a second floatation body (2), which encircles the first body (1) and the second body being adapted to move in response to waves relative to the first body (1). It also comprises energy transmission means (5, 6; 52, 53) coupled between the first and the second body, to transfer movement energy from the second body to at least one electric generator (8) on the first body. The first body (1) is anchored to the seabed by a tension leg (16), which is under a sufficient tension to prevent the first body (1) to move vertically because of the waves. The first body has a ballast chamber (29, 30), which is situated below the lowest level of the water.

Description

technical field [0001] The invention relates to a wave energy generator according to the preamble of claim 1 attached hereto. Background technique [0002] Significant efforts have been made in recent years to develop wave energy generating devices. The challenges faced by this installation are many and can be summarized as follows: [0003] • There is a need to develop a device capable of generating electrical energy at a competitive price with all costs (production, maintenance and operation) included. This means that the device must be simple and inexpensive. [0004] • Need to obtain high operational stability. Various meteorological conditions in the ocean will cause the device to suffer a lot of stress. The installation must be able to withstand storms for at least twenty years without significant damage. [0005] • Need to be able to deliver power fairly steadily. This means that the device must be able to deliver power through small and large waves of a wide ra...
