Abstract

The wave energy generation system has energy capture units with their outputs connected to a pipeline (4) delivering water jets to a Pelton wheel that drives an electric generator. Each energy capture unit has a water pump on the sea bed. As a wave rises, a float (1), connected by a rope (2), raises a weighted arm on the pump (3), drawing in sea water which is then delivered as the wave falls.

Description

DESCRIPTION La présente invention concerne un système permettant de récupérer l'énergie de la mer (houle) pour la production de masse d'énergie électrique. DESCRIPTION The present invention relates to a system making it possible to recover energy from the sea (swell) for the mass production of electrical energy.

PRINCIPE Une centrale hydroélectrique conventionnelle (turbine PELTONE), située à terre (pas loin des cotes), est alimentée en eau de mer (réseau de canalisations sous marines) par de nombreuses "pompes" immergées au fond de la mer (pas loin des cotes). Chacune de ces "pompes" est reliée à un flotteur (situé à la surface) à travers un câble tendu, une augmentation du niveau de la mer se traduit par une traction importante sur le câble, qui provoque le fonctionnement de la pompe (à piston simple effet). ELEMENTS CARACTERISTIQUES DU SYSTEME. PRINCIPLE A conventional hydroelectric power station (PELTONE turbine), located on land (not far from the coasts), is supplied with sea water (network of underwater pipes) by numerous "pumps" submerged at the bottom of the sea (not far from the coasts ). Each of these "pumps" is connected to a float (located on the surface) through a tensioned cable, an increase in sea level results in a significant traction on the cable, which causes the operation of the pump (piston single effect). CHARACTERISTIC ELEMENTS OF THE SYSTEM.

Le Flotteur (1/figl) Placé en surface de la mer, le flotteur est l'élément moteur du système. Il est relié à la pompe immergée par un câble tendu (2/figl). Quand le niveau de la mer augmente la poussée d'archimède exercée provoque une traction sur le câble. Le flotteur est équipe d'une vanne permettant son immersion en cas de mauvais temps. The Float (1 / figl) Placed on the surface of the sea, the float is the driving force of the system. It is connected to the submerged pump by a tensioned cable (2 / figl). When the sea level rises, the archimedes thrust exerted causes the cable to pull. The float is equipped with a valve allowing its immersion in bad weather.

Le Câble (2/figl) Le câble (2/figl) relie le flotteur à la pompe immergée, il doit être très résistant (des centaines de tonnes de traction selon la puissance souhaitée). The Cable (2 / figl) The cable (2 / figl) connects the float to the submerged pump, it must be very resistant (hundreds of tonnes of traction depending on the desired power).

La Pompe (3/figl) Cet ensemble est constitué d'une pompe, à piston simple effet (8/fïg2), monté sur un socle (7/fig2) et actionné par le câble (2/figl) par l'intermédiaire du contre poids (6/fig2). Le temps moteur (pompage) se produit lors de la traction du câble. Le contrepoids assure la tension du câble. Le massif (7/fïg2) maintient l'ensemble au fond de l'eau (poids très important). Le flexible (9/fig2) permet les mouvements oscillatoires de la pompe (8/fig2). The Pump (3 / figl) This set consists of a pump, with a single-acting piston (8 / fig2), mounted on a base (7 / fig2) and actuated by the cable (2 / figl) via the against weight (6 / fig2). The motor time (pumping) occurs when the cable is pulled. The counterweight ensures cable tension. The massif (7 / fïg2) keeps the whole at the bottom of the water (very important weight). The flexible (9 / fig2) allows the oscillatory movements of the pump (8 / fig2).

Les Canalisations (4/figl) Chaque pompe est reliée (en sortie) à une canalisation chargée de ramener l'eau sous pression à la surface jusqu'à l'usine. Les canalisations (peuvent être en plastique) reposent sur le fond de la mer. Toutes les canalisations de toutes les pompes se rejoignent en une canalisation unique qui alimente l'usine en eau haute pression. The pipes (4 / figl) Each pump is connected (at the outlet) to a pipe responsible for bringing the pressurized water to the surface up to the factory. The pipes (can be plastic) rest on the seabed. All the pipes of all the pumps join in a single pipe which supplies the plant with high pressure water.

L'usine (S/figl) L'usine hydroélectrique est une usine conventionnelle équipée d'une roue PELTONE pour récupérer au mieux l'énergie de l'eau.The factory (S / figl) The hydroelectric factory is a conventional factory equipped with a PELTONE wheel to recover energy from water as well as possible.

Claims (1)

REVENDICATIONCLAIM 1) Dispositif permettant la récupération de l'énergie de la mer et sa transformation en un puissant jet d'eau pouvant actionner une usine hydroélectrique conventionnelle se trouvant a proximité de la cote. Ce dispositif se caractérise par le fait qu'il se compose d'un flotteur (l/figl) placé à la surface de la mer relié par un câble tendu (2/figl) à une pompe (3/figl) qui se trouve au fond de la mer à la verticale du flotteur. Les mouvements de la mer se traduisent par des efforts de traction sur le câble, cela a pour effet de faire fonctionner la pompe. L'eau sous pression recueillie en sortie de la pompe est envoyée vers l'usine par une canalisation sous marine. Le système complet peut comporter de nombreux "ensembles" (flotteur/pompe) dans ce cas toutes les canalisations se rejoignent en une seule avant leur arrivée à l'usine.1) Device for recovering energy from the sea and transforming it into a powerful jet of water capable of operating a conventional hydroelectric plant located near the coast. This device is characterized by the fact that it consists of a float (l / figl) placed on the surface of the sea connected by a tensioned cable (2 / figl) to a pump (3 / figl) which is located bottom of the sea vertical to the float. The movements of the sea result in tensile forces on the cable, this has the effect of operating the pump. The pressurized water collected at the outlet of the pump is sent to the factory by an underwater pipe. The complete system can include many "assemblies" (float / pump) in this case all the pipes join in one before arriving at the factory.
