DISPOSITIF DE RAMASSAGE D'ALGUES MARINES OU AUTRES MATIèRE8
EN SUSPENSION DANS L'EAU
La présente invention se rapporte à un dispositif de ramassage d'algues marines ou autres matières en suspension dans l'eau.DEVICE FOR COLLECTING MARINE ALGAE OR OTHER MATERIAL8
HANGING IN WATER
The present invention relates to a device for collecting seaweed or other matter suspended in water.
Par le document FR 2.356.364, on connaît un dispositif destiné notamment au ramassage des algues marines à l'intérieur même des vagues, à l'aide d'un filet supporté par un cadre métallique lui-même supporté par une double flèche caractérisée par une structure de poutrelle en treillis de section trapézoïdale évolutive, encombrante, complexe et coûteuse à réaliser. Document FR 2,356,364 discloses a device intended in particular for collecting marine algae inside the waves, using a net supported by a metal frame itself supported by a double arrow characterized by a truss structure of a trapezoidal section which is scalable, bulky, complex and costly to produce.
La présente invention vise à proposer une nouvelle structure de support du filet, plus simple, plus pratique d'emploi et moins encombrante en position de transport. The present invention aims to provide a new net support structure, simpler, more practical to use and less bulky in the transport position.
A cet effet, l'invention a pour objet un dispositif de ramassage d'algues marines ou autres matières en suspension dans l'eau, comprenant un filet monté sur un support fixé à l'extrémité d'une potence pourvue à son autre extrémité de moyens de liaison à un engin approprié, caractérisé en ce que ledit support est constitué de deux bras arqués, articulés à l'une des extrémités d'une poutre constituant ladite potence et déployables, à l'aide de vérins interposés entre la potence et les bras, entre deux positions, l'une de déploiement des bras à la manière d'un parapluie, l'autre de rabattement des bras le long de la potence. To this end, the subject of the invention is a device for collecting seaweed or other matter suspended in water, comprising a net mounted on a support fixed to the end of a bracket provided at its other end with means of connection to an appropriate machine, characterized in that said support consists of two arched arms, articulated at one end of a beam constituting said bracket and deployable, using jacks interposed between the bracket and the arms, between two positions, one for deploying the arms like an umbrella, the other for folding the arms along the gallows.
Avantageusement, la poutre est munie, sur sa face supérieure, d'un petit mât de haubanage relié par des haubans appropriés aux deux extrémités de ladite poutre. Advantageously, the beam is provided, on its upper face, with a small guying mast connected by guy lines suitable for the two ends of said beam.
De préférence, le mât de haubanage est disposé de telle sorte que lorsque les bras sont déployés, il se trouve en alignement avec les extrémités de ceux-ci et est muni de haubans auxiliaires amovibles le reliant auxdites extrémités. Preferably, the guying mast is arranged so that when the arms are deployed, it is in alignment with the ends of the latter and is provided with removable auxiliary stays connecting it to said ends.
Les moyens de liaison de la potence à un engin approprié, tel qu'un engin de travaux publics du type Backhoe par exemple, sont avantageusement constitués par une plaque d'attelage conventionnelle permettant le montage du dispositif directement à l'extrémité de la flèche dudit engin. The means for connecting the bracket to an appropriate machine, such as a public works machine of the Backhoe type for example, are advantageously constituted by a conventional coupling plate allowing the device to be mounted directly at the end of the boom of said contraption.
D'autres caractéristiques et avantages ressortiront de la description qui va suivre d'un mode de réalisation de l'invention, description donnée à titre d'exemple uniquement, en regard des dessins annexés sur lesquels

La figure 1 représente le dispositif de ramassage d'algues marines de l'invention en configuration opérationnelle déployée. Celui-ci est constitué d'une potence ou poutre 1, dont une extrémité est munie d'une plaque d'attelage 2 et dont l'autre extrémité porte deux bras arqués articulés 3, 3' supportant un filet rectangulaire 4. FIG. 1 represents the device for collecting seaweeds of the invention in deployed operational configuration. This consists of a bracket or beam 1, one end of which is provided with a coupling plate 2 and the other end of which carries two articulated arcuate arms 3, 3 ′ supporting a rectangular net 4.
La poutre 1 est, par exemple, constituée d'un profilé métallique creux de section rectangulaire ou carrée. The beam 1 is, for example, made of a hollow metal profile of rectangular or square section.
La plaque d'attelage 2 est, par exemple, une plaque métallique rectangulaire pourvue, sur sa face opposée à la potence, d'axes et d'oreilles (non représentés) de fixation à l'extrémité de la flèche d'un engin du type Back-hoe (également non représenté), par exemple, au lieu et place d'un godet. The coupling plate 2 is, for example, a rectangular metal plate provided, on its face opposite to the bracket, pins and ears (not shown) for fixing to the end of the boom of a machine of the Back-hoe type (also not shown), for example, instead of a bucket.
Les bras arqués 3, 3' sont, par exemple, constitués de profilés métalliques creux cintrés, de section rectangulaire ou carrée. A une extrémité, ces bras 3, 3' sont articulés sur des pivots verticaux 5 solidaires de la poutre 1 et disposés sur les flancs latéraux de celle-ci. Bien entendu, la courbure des bras 3, 3' peut varier. The arcuate arms 3, 3 'are, for example, made of curved hollow metal profiles, of rectangular or square section. At one end, these arms 3, 3 'are articulated on vertical pivots 5 secured to the beam 1 and arranged on the lateral flanks of the latter. Of course, the curvature of the arms 3, 3 'can vary.
La rotation des bras 3, 3' autour des pivots 5 est assurée par des vérins hydrauliques ou pneumatiques à double effet 6, interposés entre la potence 1 et chaque bras 3, 3'. The rotation of the arms 3, 3 'around the pivots 5 is ensured by hydraulic or pneumatic double-acting cylinders 6, interposed between the bracket 1 and each arm 3, 3'.
Ces vérins 6 sont reliés par des canalisations appropriées (non représentées) à une source de fluide sous pression, par exemple celle dont est pourvu l'engin sur lequel est monté le dispositif.These jacks 6 are connected by appropriate pipes (not shown) to a source of pressurized fluid, for example that which is provided with the machine on which the device is mounted.
Le filet 4 est monté en suspension sous les bras arqués 3, 3' et y est fixé par tous moyens appropriés. The net 4 is mounted in suspension under the arcuate arms 3, 3 'and is fixed there by any appropriate means.
La potence 1 est munie d'un système de haubanage destiné à renforcer sa rigidité, constitué d'un mât de haubanage 7 et de haubans 8, de préférence constitués par des tubes ou des fers, ancrés sur le mât 7 et à chaque extrémité de la poutre 1. The bracket 1 is provided with a guy system intended to reinforce its rigidity, consisting of a guy mast 7 and guy wires 8, preferably constituted by tubes or irons, anchored on the mast 7 and at each end of beam 1.
Le dispositif comporte un système de haubanage des bras 3, 3', constitué par ledit mât de haubanage 7, de préférence en alignement avec les extrémités desdits bras 3, 3', et par des haubans 9, de préférence constitués par des câbles amovibles. The device comprises a guy system for the arms 3, 3 ′, constituted by said guy line 7, preferably in alignment with the ends of said arms 3, 3 ′, and by guy lines 9, preferably constituted by removable cables.
Enfin, en partie inférieure du filet 4, qui est lesté, un certain nombre de câbles amovibles 10 relient ledit filet à l'extrémité, coté attelage 2, de la poutre 1 en vue de maintenir ledit filet sensiblement vertical lors de l'utilisation du dispositif. Sur les figures 1 et 2, on a représenté quatre de ces câbles 10. Finally, in the lower part of the net 4, which is ballasted, a certain number of removable cables 10 connect said net to the end, on the coupling side 2, of the beam 1 in order to keep said net substantially vertical when using the device. In FIGS. 1 and 2, four of these cables 10 are shown.
Le dispositif s'utilise comme un rateau, après déploiement des bras 3, 3 à la manière d'un parapluie tel qu'illustré sur la figure 1 et amenée du dispositif au dessus de l'étendue d'eau où se trouvent les algues marines à ramasser. The device is used like a rake, after deployment of the arms 3, 3 in the manner of an umbrella as illustrated in Figure 1 and brought from the device above the body of water where the seaweed is found to pick up.
On peut éventuellement, en cours d'utilisation du dispositif et alors que le filet est immergé, replier les bras 3,3' le long de la potence, le filet se refermant ainsi sur les algues. One can possibly, during use of the device and while the net is submerged, fold the arms 3.3 'along the stem, the net thus closing on the algae.
En fin d'utilisation du dispositif, pour faciliter le transport, les bras 3, 3' sont repliés le long de la potence 1 comme illustré sur la figure 4. At the end of use of the device, to facilitate transport, the arms 3, 3 ′ are folded along the bracket 1 as illustrated in FIG. 4.
A cet effet, on retire, ou l'on attache le long des bras 3,3', les câbles 10, les haubans 9 et le filet 4, puis on actionne les vérins 6 en sorte de rabattre les bras le long de la poutre 1. For this purpose, we remove, or we attach along the arms 3.3 ', the cables 10, the shrouds 9 and the net 4, then we actuate the jacks 6 so as to fold the arms along the beam 1.
Avantageusement, le dispositif est ensuite placé sur un berceau à roulettes 11, représenté schématiquement sur la figure 4, pour faciliter son déplacement sur route. Advantageously, the device is then placed on a cradle with casters 11, shown diagrammatically in FIG. 4, to facilitate its movement on the road.
Le rabattement des bras réduit sensiblement l'encombrement en largeur du dispositif. The folding of the arms significantly reduces the overall width of the device.
I1 va de soit que la poutre 1 peut être munie de tous les équipements nécessaires à la signalisation routière (non représentés), de façon escamotable ou non. I1 goes without saying that the beam 1 can be provided with all the equipment necessary for road signs (not shown), retractable or not.
Bien entendu, l'invention ne se limite pas au mode de réalisation représenté et décrit ci-dessus, mais en couvre au contraire toutes les variantes, notamment en ce qui concerne la forme et la courbure des bras 3, 3', la forme de la poutre 1, le nombre et la disposition des câbles ou haubans. Of course, the invention is not limited to the embodiment shown and described above, but on the contrary covers all variants thereof, in particular as regards the shape and the curvature of the arms 3, 3 ′, the shape of beam 1, the number and arrangement of cables or shrouds.
