Description

Système d’allumage automatique pour dispositifs de lutte antigel. Automatic ignition system for anti-freeze devices.
Domaine technique Technical area
[0001] La présente invention concerne le domaine de la lutte antigel. En particulier, elle concerne un dispositif pour permettre le démarrage automatique des dispositifs utilisés dans la lutte antigel dans les exploitations agricoles tel que les bougies paraffines, les brûleurs ou autres. [0001] The present invention relates to the field of anti-freeze control. In particular, it relates to a device for allowing the automatic start-up of devices used in the fight against frost in agricultural operations such as paraffin candles, burners or others.
Technique antérieure Prior art
[0002] Les dispositifs de lutte antigel tel que les bougies paraffines, les brûleurs à pellets, au charbon ou à l’huile représentent une des solutions les plus utilisées par les agriculteurs pour combattre le phénomène de gel. [0002] Anti-freeze devices such as paraffin candles, pellet, coal or oil burners represent one of the solutions most used by farmers to combat the frost phenomenon.
[0003] Dans le cas des bougies paraffines par exemple, une bougie se présente sous forme d’un contenant (ex. pots métalliques) renfermant chacun près de 5 kg de paraffine. Il faut compter entre 300 et 600 bougies par hectare qui seront allumées en fonction de l’intensité du gel. Le nombre de foyers sera renforcé sur les bordures, du côté du vent dominant et/ou face aux flux d’air froid en fonction de la topographie des lieux. [0004] Une des problématiques des bougies, et les autres brûleurs, malgré leur prix abordable, réside dans la logistique nécessaire pour faire fonctionner un nombre important de bougies par hectare. En particulier la mise à feu qui nécessite un temps énorme. [0003] In the case of paraffin candles for example, a candle is in the form of a container (eg metal pots) each containing nearly 5 kg of paraffin. It takes between 300 and 600 candles per hectare which will be lit depending on the intensity of the frost. The number of homes will be increased on the edges, on the side of the prevailing wind and/or facing cold air flows depending on the topography of the area. [0004] One of the problems with candles, and other burners, despite their affordable price, lies in the logistics necessary to operate a large number of candles per hectare. In particular the firing which requires an enormous amount of time.
[0005] Les solutions présentées par l’art antérieur, malgré leur efficacité, restent dans la plupart des cas moins abordables en termes de coût et contraignantes sur le plan de déploiement au niveau des exploitations agricoles, en particulier le temps nécessaire pour la mise en marche, et aussi sur le plan de la logistique. [0005] The solutions presented by the prior art, despite their effectiveness, remain in most cases less affordable in terms of cost and restrictive in terms of deployment at the level of agricultural operations, in particular the time necessary for implementation. market, and also in terms of logistics.
[0006] Parmi les solutions adoptées par les agriculteurs, il existe l’allumeur portatif à gaz propane (ex. Flamgel) qui nécessite la présence d’un opérateur qui fait le tour de toutes les bougies pour un allumage manuel. Il permet d'allumer en moins de 5 secondes les bougies antigel pour un premier allumage, et en moins de 2 secondes pour un second allumage. Ce dispositif malgré son efficacité, sa rapidité et son faible cout, ne permet pas de résoudre la question du temps d’allumage des bougies, en particulier la synchronisation de l’opération d’allumage pour de grandes exploitations. [0006] Among the solutions adopted by farmers, there is the portable propane gas lighter (e.g. Flamgel) which requires the presence of an operator who goes around all the candles for manual lighting. It allows antifreeze candles to be lit in less than 5 seconds for a first ignition, and in less than 2 seconds for a second ignition. This device, despite its efficiency, speed and low cost, does not resolve the issue of candle lighting time, in particular the synchronization of the lighting operation for large farms.
[0007] Une autre solution est dévoilée dans le document de la demande de brevet français FR2424958A2 qui permet d’installer et d’allumer plusieurs bougies en même temps grâce à une technique qui repose sur le fait que les bougies sont reliées entre elles en série, par des cordes et que des mèches combustibles à combustion rapide s’étendant chacune depuis la couche pyrotechnique d’une bougie jusqu’à la couche pyrotechnique de la bougie suivante. Le dispositif comprend un mécanisme à allumage automatique sensible à la température. [0007] Another solution is revealed in the document of French patent application FR2424958A2 which makes it possible to install and light several candles at the same time thanks to a technique which is based on the fact that the candles are connected together in series , by ropes and fast-burning combustible wicks each extending from the layer pyrotechnic of one candle to the pyrotechnic layer of the next candle. The device includes a temperature-sensitive auto-ignition mechanism.
[0008] Cette solution est contraignante en termes de déploiement car elle est à usage unique à cause des mèches et nécessite des moyens adaptés pour transporter et placer les bougies aux bons endroits. De plus elle ne s’adapte pas à tout type de bougie. [0008] This solution is restrictive in terms of deployment because it is single-use because of the wicks and requires suitable means to transport and place the candles in the right places. In addition, it does not adapt to all types of candles.
[0009] D’où l’intérêt de la présente l’invention qui a pour objet un système automatique à usage multiple pour la mise à feu d’un dispositif de lutte antigel comme des bougies à base de paraffine. Un second objet de l’invention concerne l’automatisation de la mise à feu de ces dispositifs antigel en fonction des conditions climatiques. [0009] Hence the interest of the present invention, the subject of which is a multiple-use automatic system for igniting an anti-freeze device such as paraffin-based candles. A second object of the invention concerns the automation of the firing of these antifreeze devices depending on climatic conditions.

- Un bec pour mise à feu fait d’un matériau résistant à la chaleur et comporte une sortie pour injecter un liquide inflammable sur la surface supérieur de la bougie paraffine, et des moyens pour créer des étincelles au moment de l’injection dudit liquide. - Une pompe, qui coopère d’un côté avec le bec via un canal centrale pour propulser le liquide inflammable sur la surface supérieur de la bougie, et de l’autre côté avec un réservoir contenant le liquide inflammable. - A nozzle for ignition made of a heat-resistant material and has an outlet for injecting a flammable liquid onto the upper surface of the paraffin candle, and means for creating sparks at the time of injection of said liquid. - A pump, which cooperates on one side with the nozzle via a central channel to propel the flammable liquid onto the upper surface of the candle, and on the other side with a reservoir containing the flammable liquid.
- Un coffret de commande comprenant une carte électronique, et une source d’alimentation électrique. Ladite carte électronique est reliée à un moyen de mesure de la température extérieure du milieu où se trouve le dispositif et permet de déclencher le processus de mise à feu de manière automatique en activant la pompe et le circuit de création des étincelles. - A control box including an electronic card and an electrical power source. Said electronic card is connected to a means of measuring the external temperature of the environment where the device is located and makes it possible to trigger the ignition process automatically by activating the pump and the spark creation circuit.
[0011] L’ensemble est positionné de manière à ce que le bec se trouve à proximité de la surface supérieure de la bougie. En effet, un bec en forme se ‘S’ est agencé à une base contenant la pompe . Ladite pompe coopère directement avec le réservoir du liquide inflammable pour transporter le liquide inflammable vers la sortie du bec. Un moyen de mesure de la température environnante est intégré au niveau du coffret de commande. Au niveau du bec, deux électrodes sont installées des deux côtés du conduit central du liquide inflammable pour permettre la production des étincelles lorsque la pompe est activée. L’ensemble est alimenté par une source électrique indépendante telle qu’une batterie et commandé par une carte électronique intégrée au niveau du coffret. Description sommaire des dessins The assembly is positioned so that the nozzle is close to the upper surface of the candle. In fact, an 'S' shaped nozzle is arranged on a base containing the pump. Said pump cooperates directly with the flammable liquid reservoir to transport the flammable liquid to the outlet of the nozzle. A means of measuring the surrounding temperature is integrated into the control box. At the nozzle, two electrodes are installed on both sides of the central flammable liquid conduit to allow sparks to be produced when the pump is activated. The assembly is powered by an independent electrical source such as a battery and controlled by an electronic card integrated into the box. Summary description of the drawings

[0013] Le système de l’invention selon les figures 1 et 2, comporte un réservoir pour liquide inflammable, une pompe pour pulvériser ledit liquide, un système d’allumage comprenant deux électrodes positionnées des deux côtés du canal de pulvérisation du liquide inflammable et un générateur d’étincelles. [0013] The system of the invention according to Figures 1 and 2 comprises a reservoir for flammable liquid, a pump for spraying said liquid, an ignition system comprising two electrodes positioned on both sides of the flammable liquid spray channel and a spark generator.
[0014] Dans une configuration avantageuse, les deux électrodes et le canal de pulvérisation sont installés dans un support sous forme de ‘bec’ fait d’un matériau résistant au feu et ayant une forme de préférence en forme de “S” de manière à ce que la partie supérieure du support est orientée à l’intérieur de la bougie, en direction de la surface supérieure en paraffine. Ledit support est constitué de trois canaux. Un canal central servant de moyen pour acheminer le liquide inflammable vers la surface de la bougie, et deux demi-canaux à droite et à gauche pour recevoir les électrodes d’allumage. Selon un mode réalisation particulier, le bec est fait à partir d’une argile réfractaire afin de garantir une parfaite résistance au feu. Les électrodes électriques de mise à feu sont protégées par une couche de matière céramique. [0014] In an advantageous configuration, the two electrodes and the spray channel are installed in a support in the form of a 'spout' made of a fire-resistant material and having a shape preferably in the shape of an “S” so as to that the upper part of the support is oriented inside the candle, towards the upper paraffin surface. Said support consists of three channels. A central channel serving as a means to deliver the flammable liquid to the surface of the spark plug, and two half-channels on the right and left to receive the ignition electrodes. According to a particular embodiment, the nozzle is made from refractory clay in order to guarantee perfect fire resistance. The electric ignition electrodes are protected by a layer of ceramic material.
[0015] Tel qu’illustré par la figure 1 , le bec (1) en « S » coopère avec le coffret de commande (2) via sa partie inférieure pour isoler le circuit d’alimentation en liquide inflammable de la source de chaleur. [0016] Selon une configuration avantageuse (figure 2), le système peut s’accrocher au dispositif de lutte antigel telle une bougie grâce à la forme en « S » de son bec (1). Le coffret de commande (3) et le réservoir (4) sont situés à un niveau plus bas pour éviter tout contact avec la chaleur. Le bec (1) en matériau résistant au feu, de préférence à base d’une argile réfractaire, constitue un bouclier de protection et d’isolation des autres composants de la source de chaleur. As illustrated in Figure 1, the “S” shaped nozzle (1) cooperates with the control box (2) via its lower part to isolate the flammable liquid supply circuit from the heat source. [0016] According to an advantageous configuration (Figure 2), the system can attach to the antifreeze device like a candle thanks to the “S” shape of its nozzle (1). The control box (3) and the tank (4) are located at a lower level to avoid contact with heat. The nozzle (1) made of fire-resistant material, preferably based on refractory clay, constitutes a protective and insulating shield from the other components of the heat source.
Comme illustré à la figure 5, la forme en « S » et la disposition verticale du bec (1) permet de vider le conduit central (9) du liquide inflammable et d’éviter tout risque d’incendie du système. As illustrated in Figure 5, the “S” shape and vertical arrangement of the spout (1) makes it possible to empty the central conduit (9) of the flammable liquid and avoid any risk of fire in the system.
[0017] Dans un mode de réalisation préféré, le liquide inflammable est choisi parmi le fuel, le bioéthanol, le diesel, et de préférence l’essence, ou toute autre matière qui présente moins de risque d’incendie ou d’explosion. [0017] In a preferred embodiment, the flammable liquid is chosen from fuel oil, bioethanol, diesel, and preferably gasoline, or any other material which presents less risk of fire or explosion.
Le réservoir du liquide inflammable, tel qu’illustré par la figure 3, dispose de moyen d’assemblage avec le boitier de commande. The flammable liquid tank, as illustrated in Figure 3, has a means of assembly with the control box.
[0018] Selon un mode particulier, le système de l’invention comporte un bouton (17) au niveau du coffret (3) pour une activation manuelle du circuit de d’allumage. Cette disposition permet d’allumer individuellement les bougies en cas de besoin sans passer par le circuit automatique basé sur la mesure de la température environnante. Le système est configuré aussi pour un démarrage à distance par des moyens appropriés tel une télécommande ou une application informatique (ex. application mobile). [0019] Selon un mode de réalisation avantageux illustré à la figure 9, le bec (1), la pompe et le réservoir sont agencés via une base (2) pour que le liquide inflammable passe directement du réservoir (4) au conduit central (9) via la pompe (12) grâce aux connecteurs (13 et 14) de ladite pompe. Cette configuration permettra de protéger le dispositif de tout risque d’incendie en protégeant le circuit du liquide inflammable de toute agression externe. Avantageusement, la base est faite de matériau réfractaire pour protéger le circuit du liquide inflammable de tout risque d’incendie. [0018] According to a particular mode, the system of the invention comprises a button (17) at the level of the box (3) for manual activation of the ignition circuit. This arrangement allows the candles to be lit individually if necessary without going through the automatic circuit based on measuring the surrounding temperature. The system is also configured for remote starting by appropriate means such as a remote control or a computer application (e.g. mobile application). According to an advantageous embodiment illustrated in Figure 9, the nozzle (1), the pump and the reservoir are arranged via a base (2) so that the flammable liquid passes directly from the reservoir (4) to the central conduit ( 9) via the pump (12) thanks to the connectors (13 and 14) of said pump. This configuration will protect the device from any risk of fire by protecting the flammable liquid circuit from any external attack. Advantageously, the base is made of refractory material to protect the flammable liquid circuit from any risk of fire.
[0020] Selon un autre aspect de l’invention, le coffret de commande (3) comprend une carte électronique pour commander l’allumage de la bougie (6) grâce à un moyen de prélèvement de la température externe, et une source d’excitation électrique telle une batterie. Selon l’invention, lorsque la température externe atteint une valeur prédéfinie, le dispositif déclenche l’allumage de la bougie en activant premièrement la pompe (12) pour projeter une quantité du liquide inflammable sur la surface de la bougie (6) et ensuite les électrodes (10, 10’) sont activées pendant une durée déterminée grâce à un générateur d’étincelles (5). [0020] According to another aspect of the invention, the control box (3) comprises an electronic card for controlling the ignition of the candle (6) using means for sampling the external temperature, and a source of electrical excitation like a battery. According to the invention, when the external temperature reaches a predefined value, the device triggers the ignition of the candle by first activating the pump (12) to project a quantity of the flammable liquid onto the surface of the candle (6) and then the electrodes (10, 10') are activated for a determined duration using a spark generator (5).
[0021] Selon un mode avantageux, le système est configuré pour permettre le réglage de la température de référence pour déclencher l’allumage. [0021] According to an advantageous mode, the system is configured to allow adjustment of the reference temperature to trigger ignition.
