Abstract

Sea waves are used to operate air pumps, and the compressed air is piped to the shore where it is stored to provide electric energy. The appts. has two slotted vertical columns that are fixed to the sea bed, and two rods are placed in the slots such that the rods, which lie parallel to the wave front, are free to rise and fall vertically. A large float carries the two rods and has, mounted on its sides, air pumps whose piston is pushed inwards by an arm attached to two flat plates at right angles to each other, and which lie face on to the waves so as to be rocked about a pivot formed by the lower rod by the wave motion. A counterweight which is connected to the pump piston restores the piston to the outermost position.

Description

L'invention est relative à une installation pour emmagasiner l'énergie produite par le mouvement des vagues de la mer ou de l'océan. The invention relates to an installation for storing the energy produced by the movement of sea or ocean waves.

Une installation de ce genre doit être simple et robuste de façon que son entretien ne soit pas couteux et doit être formée d'organes résistant à la corrosion par l'eau de mer. An installation of this kind must be simple and robust so that its maintenance is not costly and must be formed of bodies resistant to corrosion by sea water.

L'installation selon l'invention répond à ces conditions. The installation according to the invention meets these conditions.

Elle est caractérisée en ce que, comportant un flotteur pivotant autour d'un axe de position fixe en projection horizontale duquel est en saillie un montant émergeant au-dessus de l'eau, elle comprend en outre une pompe dont l'organe d'actionnement est entraîné par le montant du flotteur pivotant afin de comprimer un gaz tel que de l'air. It is characterized in that, comprising a float pivoting about an axis of fixed position in horizontal projection from which protrudes an upright emerging above the water, it further comprises a pump whose actuating member is driven by the pivoting float upright to compress a gas such as air.

Dans un mode de réalisation, une canalisation amène le gaz comprimé à terre où il est stocké. I1 peut etre u-tili-sE- - pour actionner une turbine entrainant une génératrice d'électricité. In one embodiment, a pipeline brings the compressed gas to the ground where it is stored. I1 can be u-tili-sE- - to activate a turbine driving an electricity generator.

D'autres caractéristiques de l'invention apparaîtront avec la description de certains de ses modes de réalisation, celle-ci étant effectuée en se référant aux dessins ci-annexés sur lesquels
la figure 1 est une vue de côté d'une installation selon une réalisation;
la figure 2 est une vue suivant la flèche f de la figure 1; et
la figure 3 montre un détail de l'installation.Other characteristics of the invention will appear with the description of some of its embodiments, this being carried out with reference to the attached drawings in which
Figure 1 is a side view of an installation according to one embodiment;
Figure 2 is a view along arrow f of Figure 1; and
Figure 3 shows a detail of the installation.

Deux poteaux verticaux 1 et 2 fixés au fond de la mer et émergeant toujours au-dessus de l'eau présentent chacun une fente 5 à bords verticaux 6 et 7 servant au guidage d'un arbre horizontal 8 et d'une barre 9 également horizontale. Two vertical posts 1 and 2 fixed to the bottom of the sea and always emerging above the water each have a slot 5 with vertical edges 6 and 7 used for guiding a horizontal shaft 8 and a bar 9 also horizontal .

Les extrémités de l'arbre 8 dépassent de l'intervalle séparant les poteaux 1 et 2 et ces extrémités sont solidaires de corps flottants 3 et 4 ayant une forme de révolution d'axe confondu avec celui de l'arbre 8. The ends of the shaft 8 protrude from the interval separating the posts 1 and 2 and these ends are integral with floating bodies 3 and 4 having a shape of revolution of axis coincident with that of the shaft 8.

L'arbre 8 est également solidaire d'une paroi ou front 11 faisant face au large, par l'intermédiaire d'une plaque rectangulaire 12 perpendiculaire au front 11. Deux montants 13 et 14 sont perpendiculaires à la plaque 12 au-dessus de cette dernière et au droit de l'arbre 8. Le front 11 se termine, à l'opposé de la plaque 12, par des rebords 15 et 16 qui lui sont perpendiculaires, l'un en avant et l'autre en arrière dudit front. The shaft 8 is also secured to a wall or front 11 facing offshore, by means of a rectangular plate 12 perpendicular to the front 11. Two uprights 13 and 14 are perpendicular to the plate 12 above this last and in line with the shaft 8. The front 11 ends, opposite the plate 12, by flanges 15 and 16 which are perpendicular to it, one in front and the other behind said front.

La barre horizontale 9 est solidaire de deux parois verticales 20 et 21 disposées entre les montants 1 et 2, à proximité de ces dernières et qui sont traversées par l'arbre 8. The horizontal bar 9 is integral with two vertical walls 20 and 21 arranged between the uprights 1 and 2, near the latter and which are crossed by the shaft 8.

Entre ces deux parois 20 et 21 sont disposés, au-dessus de la plaque 12, deux profilés en U 22 et 23 de positions symétriques par rapport au plan vertical 24 passant par les lignes moyennes des fentes 5 et dont chacun comporte, par exemple le profilé 22r une base large 25 disposée en oblique entre les parois 20 et 21 ainsi que deux branches 26 et 27 appliquées contre les parois 20 el2421. Between these two walls 20 and 21 are arranged, above the plate 12, two U-shaped profiles 22 and 23 of symmetrical positions with respect to the vertical plane 24 passing through the mean lines of the slots 5 and each of which comprises, for example the profile 22r a wide base 25 disposed obliquely between the walls 20 and 21 as well as two branches 26 and 27 applied against the walls 20 el2421.

La base 25 supporte les corps 28 et 29 de deux pompes à air, respectivement 30 et 31, de façon telle que l'axe de chaque corps soit perpendiculaire à la base 25. Les tiges de commande 32 et 33 des pompes sont tournées vers les montants 13, 14 correspondants. A l'extrémité de chaque tige, par exemple celle de référence 33, est fixée une plaque 34 perpendiculaire à l'axe de cette tige portant deux galets 35 et 36 (figure 3) d'axe perpendiculaire à la tige et entre lesquels est fixée l'extrémité 37 d'un câble 38 traversant la paroi voisine 21 et à l'autre extrémité duquel est fixé un contrepoids 40. The base 25 supports the bodies 28 and 29 of two air pumps, respectively 30 and 31, so that the axis of each body is perpendicular to the base 25. The control rods 32 and 33 of the pumps are turned towards the corresponding amounts 13, 14. At the end of each rod, for example that of reference 33, is fixed a plate 34 perpendicular to the axis of this rod carrying two rollers 35 and 36 (Figure 3) of axis perpendicular to the rod and between which is fixed the end 37 of a cable 38 passing through the neighboring wall 21 and at the other end of which a counterweight 40 is fixed.

La partie supérieure de chacun des montants 13, 14 présente une fente 13a, 14a à bords verticaux. The upper part of each of the uprights 13, 14 has a slot 13a, 14a with vertical edges.

Les galets 35 et 36 permettent un contact à roulement entre les tiges 32 et 33 et les montants 13, 14 correspondants. Lors de ce contact, l'extrémité 37 du câble 38 est en regard de la fente correspondante 13a, 14a. The rollers 35 and 36 allow rolling contact between the rods 32 and 33 and the corresponding uprights 13, 14. During this contact, the end 37 of the cable 38 faces the corresponding slot 13a, 14a.

De façon analogue, le profilé 23 porte des pompes 45, 46 identiques aux pompes 30, 31 et disposées symétriquemént de ces dernières par rapport au plan vertical 24. Similarly, the section 23 carries pumps 45, 46 identical to the pumps 30, 31 and arranged symmetrically between the latter relative to the vertical plane 24.

Toutes les sorties des pompes à air sont reliées à une canalisation 50 qui dirige l'air comprimé par lesdites pompes vers une turbine disposée sur la côte et entraînant une génératrice d'énergie électrique (non montrées). All the outputs of the air pumps are connected to a pipe 50 which directs the air compressed by said pumps to a turbine arranged on the coast and driving an electric power generator (not shown).

Dans la canalisation de sortie de chaque pompe est prévue une vanne anti-retour (non représentée) empêchant que l'air comprimé produit par la pompe ne revienne vers cette dernière. In the outlet pipe of each pump is provided a non-return valve (not shown) preventing the compressed air produced by the pump from returning to the latter.

Le fonctionnement de l'installation est le suivant
Les vagues frappant le front 11 font osciller ce dernier autour de l'axe de l'arbre horizontal 8. De cette manière, les montants 13 et 14 pivotent également autour de l'axe de l'arbre 8 et poussent alternativement les tiges de commande ou de manoeuvre des pompes 45, 46 puis 30, 31 dans leurs corps.The operation of the installation is as follows
The waves hitting the front 11 cause the latter to oscillate around the axis of the horizontal shaft 8. In this way, the uprights 13 and 14 also pivot around the axis of the shaft 8 and push the control rods alternately. or to operate the pumps 45, 46 then 30, 31 in their bodies.

L'air comprimé ainsi produit actionne ladite turbine qui entraîne elle-même une génératrice. The compressed air thus produced activates said turbine which itself drives a generator.

Les contrepoids 40 sont destinés à sortir chaque tige de manoeuvre du corps de pompe correspondant quand le montant 13 ou 14 ne pousse plus cette tige. The counterweights 40 are intended to exit each operating rod from the corresponding pump body when the upright 13 or 14 no longer pushes this rod.

En variante, à la place de contrepoids on prévoit des ressorts de rappel. As a variant, instead of counterweights, return springs are provided.

L'ensemble est tel que la plaque 12 est toujours légèrement au-dessus du niveau de la mer et ainsi les pompes sont toujours hors de l'eau, évitant ainsi la corrosion. The assembly is such that the plate 12 is always slightly above sea level and thus the pumps are always out of the water, thus avoiding corrosion.

L'installation est de réalisation particulièrement simple et n'entraîne pas de pollution. The installation is particularly simple and does not cause pollution.

Dans une réalisation, des moyens de butée et des amortisseurs sont prévus pour empêcher un choc violent -qui pourrait se produire notamment en cas de tempête- des montants 13, 14 contre les organes d'actionnement des pompes.  In one embodiment, abutment means and shock absorbers are provided to prevent a violent shock - which could occur in particular in the event of a storm - of the uprights 13, 14 against the actuating members of the pumps.
