Abstract

The invention relates to a floating device making it possible to propel lightweight vessels equipped with a rear plate or with a motor seat, and to deliver pressurised water. It consists of a shell 1, of coupling clamps 2 at the rear of the vessel 3, of a motor-pump 4, which sucks water through the opening 5 and rejects it under pressure through a duct 6 towards a pressurised water control and treatment device, and of its propulsion effect 7, 8, 9, 10, 11. The device according to the invention is intended in particular for the propulsion of lightweight vessels and for the use of pressurised water.

Description

La présente invention concerne un groupe de propulsion et de projection d'eau sous pression hors bord destiné aux embarcations légères. The present invention relates to a propulsion and spraying group of outboard pressurized water intended for light boats.

Les moteurs hors bord traditionnels sont des systèmes à hélice, ayant un tirant d'eau important, ne flottant pas, remplissant une seule fonction: la propulsion. Traditional outboard engines are propeller systems, having a large draft, not floating, fulfilling a single function: propulsion.

Les moteurs à jet d'eau traditionnels, ne sont pas hors bord, et ne permettent pas l'utilisation de l'eau sous pression à un autre usage que propulsif de façon aisée. Traditional water jet engines are not outboard and do not allow pressurized water to be used other than propellant easily.

Les groupes moto-pompes traditionnels ne sont pas adaptés un usage propulsif. The traditional motor-pump units are not suitable for propulsive use.

Le dispositif selon l'invention permet de lier les avantages des moteurs hors bord traditionnels, des moteurs à jet d'eau, et des moto-pompes, en un seul produit assurant sa propre flottabilité. The device according to the invention makes it possible to link the advantages of traditional outboard motors, water jet motors, and motor pumps, in a single product ensuring its own buoyancy.

I1 comprend en effet une coque autonome assurant la flottabilité du dispositif, un système de presse d'acouplement de cette coque à un tableau arrière ou à une chaise moteur; dans cette coque est fixé un groupe moto-pompe aspirant l'eau par une ouverture située au bas de la coque, et la refoulant, par l'intermédiaire d'un système classique de tubulures, vers l'arrière. Des joints sont disposés entre la pompe et la coque pour assurer l'indépendance du circuit sous pression. La sortie de la tubulure est équipée d'un raccord permettant l'adaptation d'un système quelconque de traitement de l'eau sous pression. I1 indeed comprises an autonomous hull ensuring the buoyancy of the device, a press system for coupling this hull to a transom or to a motor chair; in this hull is fixed a motor-pump unit sucking the water through an opening located at the bottom of the hull, and driving it back, by means of a classic system of pipes, towards the rear. Seals are placed between the pump and the shell to ensure the independence of the pressure circuit. The outlet of the tubing is equipped with a connector allowing the adaptation of any system for treating pressurized water.

Dans une forme de réalisation préférentielle, le système en question est une lance pivotante assurant la maitrise en direction et en valeur, de l'effet propulsif. In a preferred embodiment, the system in question is a pivoting lance ensuring control in direction and in value, of the propulsive effect.

En variante, la lance est équipée d'un tube de Venturi aspirant de l'air dans le jet d'eau, et permettant l'oxygé- nation du plan d'eau parcouru. As a variant, the lance is equipped with a Venturi tube sucking air into the water jet, and allowing the oxygenation of the body of water traversed.

La planche unique représente, en coupe schématique, un dispositif selon l'invention. The single plate represents, in schematic section, a device according to the invention.

Le dispositif selon la planche unique, comporte une coque en polyester armé d'environ 90 cm.de longueurCi) acouplé au moyen de presses (2) au tableau arrière d'un bateau (3), par exemple un canot pneumatique. Un groupe moto-pompe (4) composé d'un moteur il cv. à refroidissement à air, à arbre vertical, et d'une pompe centrifuge, est fixé, avec interposition d'un joint étanche, au moyen de vis inoxda - bles, au fond de la coque. L'eau est aspirée à travers l'orifice (5) et refoulée à travers la tubulure (6) vers une lance (9)articulée, en partie arrière sur une dame de nage (10), en partie avant sur une chape (8) montée sur un coulisseau coulissant sur un rail (7). Le tracé en pointillé représente la variante équipée d'un tube de Venturi (11) pour l'oxygénation du plan d'eau. The device according to the single board, comprises a reinforced polyester hull of about 90 cm in length (C) coupled with presses (2) to the transom of a boat (3), for example an inflatable boat. A motor-pump unit (4) composed of an il cv motor. air cooled, vertical shaft, and a centrifugal pump, is fixed, with the interposition of a seal, by means of stainless screws, at the bottom of the hull. The water is sucked through the orifice (5) and discharged through the tubing (6) to a lance (9) articulated, in the rear part on a line (10), in the front part on a yoke (8 ) mounted on a slide sliding on a rail (7). The dotted line represents the variant equipped with a Venturi tube (11) for the oxygenation of the water body.

Le dispositif selon l'invention est particulièrement destiné à la propulsion d'embarcations légères dans des plans d'eau très peu profonds, et d'usage spécifique tels que lutte contre les incendies, lutte contre la pollution.  The device according to the invention is particularly intended for the propulsion of light boats in very shallow bodies of water, and for specific use such as fire fighting, pollution fighting.
