Title
(EN) AN APPARATUS FOR HARVESTING ENERGY FROM A BODY OF WATER AND A METHOD
(FR) DISPOSITIF DE COLLECTE D'ÉNERGIE À PARTIR D'UNE MASSE D'EAU ET PROCÉDÉ
Abstract
(EN) The invention relates to a device for harnessing energy from a body of water, which device - comprises a Darrieus rotor having at least two Darrieus rotor blades, and - comprises at least two connecting arms which connect the Darrieus rotor blades with a central axis, wherein per Darrieus rotor blade a first, proximal section of a connecting arm is connected to the central axis and a point of the connecting arm situated at a distance of the proximal section is connected to a first point on the Darrieus rotor blade, wherein - at least the connection between the point of a connecting arm situated at a distance of the first proximal section and the first point on a Darrieus blade is a hingable connection, - for every Darrieus rotor blade, of at least one connecting arm the connection between the proximal section of the connecting arm and the central axis is a rigid connection.
(FR) L'invention concerne un dispositif de collecte d'énergie à partir d'une masse d'eau, ledit dispositif comprenant un rotor Darrieus comprenant au moins deux pales de rotor Darrieus, et comprenant au moins deux bras de connexion qui connectent les pales de rotor Darrieus à un axe central, dans lequel, par pale de rotor Darrieus, une première section proximale d'un bras de connexion est connectée à l'axe central, et un point du bras de connexion qui est situé à une distance de la section proximale est connecté à un premier point sur la pale de rotor Darrieus, dans lequel au moins la connexion entre le point d'un bras de connexion situé à une distance de la première section proximale et le premier point sur une pale de rotor Darrieus est une connexion articulée; et pour chaque pale de rotor Darrieus, au moins un bras de connexion entre la section proximale du bras de connexion et l'axe central est une connexion rigide.
