Abstract

The rack has a rechargeable battery (1), integrated in a module, connected to a charger (2) recharging the battery, and a power converter (3) supplying an amplifier with a sinusoidal electric signal. The battery and converter are cooled by forced ventilation from a cold source, and are carried by a supporting bar (15) with rollers (9). Orifices (11) allow introducing threaded rods fixing the battery and the converter to the rack.

Description

La présente invention concerne un système d'énergie autonome, dénomméThe present invention relates to an autonomous energy system, referred to

rack, caractérisé en ce qu'il est constitué d'éléments modulaires réalisé en plastique type polyamide ABS. Le rack se présente comme un ensemble modulaire et autonome pour être utilisé pour une alimentation électrique extérieure par l'intermédiaire d'interface électronique, rack, characterized in that it consists of modular elements made of plastic type ABS polyamide. The rack is a modular, stand-alone unit that can be used for external power supply via electronic interface.

éventuellement intégré dans le rack, ou extérieur à ce dernier. possibly integrated in the rack, or outside the rack.

Il est diffusé dans le commerce des types de rack afin de transporter les systèmes de sonorisation; ces types de rack sont généralement non modulables et reliés au secteur électrique, donc non autonomes. En outre, la qualité de la modulation sinusoïdale est souvent très mauvaise. It is commercially available rack types to carry sound systems; these types of rack are generally non-adjustable and connected to the electrical sector, so not autonomous. In addition, the quality of the sinusoidal modulation is often very bad.

La présente invention dénommée système d'énergie autonome est caractérisée en ce qu'elle comporte une batterie d'accumulateurs rechargeable, intégrée dans un module, un chargeur (2) dont la tension est adaptée à la batterie d'accumulateurs (1) utilisée, un convertisseur de puissance (3) adapté à la puissance des batteries d'accumulateurs et fournissant un signal électrique sinusoïdal pur, un amplificateur extérieur; l'ensemble des modules constitue un rack autonome monté sur roulettes, traversé par une ventilation forcée; les modules sont reliés entre eux par une tige filetée verticale, l'ensemble du rack est recouvert d'un capot (14) escamotable, et porté par un support (15) modulable doté de roulettes (9). The present invention denominated autonomous energy system is characterized in that it comprises a rechargeable accumulator battery, integrated in a module, a charger (2) whose voltage is adapted to the accumulator battery (1) used, a power converter (3) adapted to the power of the storage batteries and providing a pure sinusoidal electrical signal, an external amplifier; the set of modules is an autonomous rack mounted on wheels, crossed by a forced ventilation; the modules are interconnected by a vertical threaded rod, the entire rack is covered by a cover (14) retractable, and carried by a support (15) adjustable with wheels (9).

L'invention ainsi résumée sera mieux comprise grâce au dessin annexé représentant l'extérieur du système, qui n'est présenté qu'à titre d'exemple non limitatif. The invention thus summarized will be better understood thanks to the attached drawing showing the outside of the system, which is presented by way of non-limiting example.

La figure 1 de la planche unique représente le système d'énergie autonome appelé rack réalisé en plastique polyamide. Figure 1 of the single board represents the autonomous energy system called rack made of polyamide plastic.

En se reportant à la figure 1 de la planche unique, le système d'énergie autonome ou rack, est enfermé au moyen de panneaux (5) et (8) démontables en sections pour recevoir les différents modules normalement nécessaires. Referring to Figure 1 of the single board, the autonomous energy system or rack, is enclosed by means of panels (5) and (8) removable in sections to receive the different modules normally required.

2 2882201 Le générateur d'énergie rechargeable est obtenu au moyen d'une batterie d'accumulateurs (1) de plusieurs centaines d'ampères facilement interchangeables. Les batteries d'accumulateurs (1) logées dans les modules sont rechargées au moyen du chargeur (2) fournissant une puissance adaptée aux batteries d'accumulateurs adaptées à la puissance demandée. Le courant continu des batteries d'accumulateurs est transformé en courant sinusoïdal pur au moyen d'un convertisseur (3). Le signal sinusoïdal pur est transmis à un amplificateur extérieur pour être traité par les récepteurs quelconques. 2 2882201 The rechargeable energy generator is obtained by means of a storage battery (1) of several hundred amperes easily interchangeable. The accumulator batteries (1) housed in the modules are recharged by means of the charger (2) providing a power adapted to the storage batteries adapted to the power demanded. The direct current of the accumulator batteries is converted into pure sinusoidal current by means of a converter (3). The pure sinusoidal signal is transmitted to an external amplifier to be processed by any receivers.

L'ensemble des modules contenus dans le système d'énergie autonome, ou rack, est fixé au moyen de tiges filetées verticales traversant au niveau des orifices (13) toute la hauteur 10 du rack fixant ainsi les modules par serrage. The set of modules contained in the autonomous energy system, or rack, is fixed by means of vertical threaded rods passing through the orifices (13) all the height of the rack thus fixing the modules by clamping.

Les batteries d'accumulateurs (1) sont soutenues au moyen d'une barre (12) latérale servant de support au rack et portée par la barre de soutien général (15). The storage batteries (1) are supported by means of a lateral bar (12) serving as support for the rack and carried by the general support bar (15).

Le rack est rendu autonome et déplacé au moyen de roues (9) reliées à la barre de soutien général (15) et aux poignées rétractables (4). The rack is made autonomous and moved by means of wheels (9) connected to the general support bar (15) and the retractable handles (4).

L'ensemble modulaires est refroidi au moyen d'une ventilation pulsée (10) issue d'une source froide. The modular assembly is cooled by means of a pulsed ventilation (10) from a cold source.

Les modules sont maintenus au rack au moyen d'orifices (11) permettant l'introduction des tiges et pratiqués sur le devant et l'arrière du caisson. The modules are held in the rack by means of orifices (11) allowing the introduction of the rods and made on the front and back of the box.
