DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
En líneas generales, el dispositivo para accionar extintores contra incendios, objeto de la invención, está constituido por una carcasa que se acopla al cuerpo del extintor, provista de ventanas en correspondencia con los puntos donde se encuentran en el interior unas cápsulas de colores, tal como verde y rojo, las cuales activan el mecanismo correspondiente, según sea la temperatura exterior. Puede haber dos o más cápsulas dependiendo de las
necesidades del usuario y de los fines que se persiga con el extintor.In general, the device for actuating fire extinguishers, object of the invention, is constituted by a housing that is coupled to the body of the extinguisher, provided with windows in correspondence with the points where colored capsules are inside, such as green and red, which activate the corresponding mechanism, depending on the outside temperature. There may be two or more capsules depending on the needs of the user and the purposes pursued with the extinguisher.
Cuando las cápsulas entran en contacto con el fuego, o captan la temperatura exterior cuando aumenta de modo considerable, se rompen o se contraen por deformación plástica a consecuencia del calor, activando el mecanismo correspondiente de tipo eléctrico y/o avisando mediante un circuito de alarma de que se ha producido una elevación de temperatura. Si esta elevación de temperatura aumentara o desembocara en un incendio, se rompería la otra cápsula, u otras, activándose otro de los circuitos que provoca la explosión del extintor para liberar la carga que extingue el fuego. En el interior de la carcasa se encuentra una pila de 1,5 voltios, con una capacidad de duración del orden de 3 ó 4 años.When the capsules come into contact with the fire, or they capture the outside temperature when it increases considerably, they break or contract due to plastic deformation due to heat, activating the corresponding mechanism of electrical type and / or warning by means of an alarm circuit that a temperature rise has occurred. If this temperature rise increases or leads to a fire, the other capsule, or others, will break, activating another circuit that causes the extinguisher to explode to release the fire extinguishing charge. Inside the housing is a 1.5 volt battery, with a capacity of the order of 3 or 4 years.
Cada una de las cápsulas está vinculada a un dispositivo interruptor eléctrico susceptible de ser actuado cuando se debilita o funde la cápsula, asistido por el correspondiente muelle que provoca el cierre del circuito de alarma y/o la inflamación del dispositivo cerilla que hará explosionar la carga.Each of the capsules is linked to an electrical switch device that can be operated when the capsule is weakened or melted, assisted by the corresponding spring that causes the alarm circuit to close and / or the inflammation of the match device that will cause the charge to explode. .
Si el calor aumentara súbitamente y se produce el fuego, también explosionará el extintor al deflagar la mecha conectada al dispositivo pirotécnico del extintor.If the heat increases suddenly and the fire is produced, the fire extinguisher will also explode when the wick connected to the pyrotechnic device of the extinguisher is deflated.

En la figura 2 vemos su estructura mostrada de forma explosionada y con secciones para ver su interior. Dispone en este caso de dos cápsulas 2 y 3 dispuestas linealmente en el interior de la carcasa 4 que agrupa el conjunto, separadas por el distanciador 5. El otro extremo de las respectivas cápsulas 2 y 3 apoya en la embocadura del orificio axial previsto en las piezas 6 y 7 en las que se guía el respectivo vastago 8 de un dispositivo interruptor 9 del que forma parte la valona 10 del extremo del vastago 8 y los terminales eléctricos 11 dispuestos radialmente en las piezas 6 y 7 y que emergen al vaciado interior en el que se desplaza la valona 10 que es el elemento que llega a establecer contacto con ellos, asistida por el respectivo muelle 12.In figure 2 we see its structure shown in an exploded way and with sections to see its interior. In this case, it has two capsules 2 and 3 arranged linearly inside the housing 4 that groups the assembly, separated by the spacer 5. The other end of the respective capsules 2 and 3 rests on the mouth of the axial hole provided in the pieces 6 and 7 in which the respective rod 8 of a switch device 9 of which the wall 10 of the end of the rod 8 and the electrical terminals 11 arranged radially in parts 6 and 7 are guided and which emerge into the internal drain in the one that moves the wall 10 which is the element that comes into contact with them, assisted by the respective spring 12.
La referencia 13 designa la pila que se encuentra en el interior de la carcasa 4.
Como dijimos anteriormente, las cápsulas 2 y 3 son capaces de soportar diferentes temperaturas del exterior sin romperse. Cuando la temperatura se eleva actúan como fusibles y es primero una de ellas la que se rompe o deforma haciendo que el vastago del interruptor 9 vinculado a ella se desplace axialmente asistido por su muelle 12 de forma que la valona 10 cierra el circuito correspondiente al establecer contacto con los terminales 11. Si la temperatura sigue ascendiendo, será la otra cápsula 3 la que provoque, al fundirse, el cierre del otro interruptor 9 vinculado a la carga explosiva del interior de dispositivo de extinción referenciado en este caso en general con el número 14 y que tenga así lugar la evacuación del producto de extinción. Los interruptores 9 pertenecen por tanto a respectivos circuitos eléctricos alimentados por la pila 13 o conectados a cualquier otro circuito. En uno de ellos queda intercalado el dispositivo de alarma vinculado a una de las cápsulas 2. El otro circuito, vinculado a la otra cápsula 3, tiene los cables conectados a una cerilla 15 que queda introducida en el interior del extintor 14, en contacto íntimo con la carga explosiva.Reference 13 designates the battery inside the housing 4. As we said before, capsules 2 and 3 are able to withstand different temperatures outside without breaking. When the temperature rises they act as fuses and it is first one of them that breaks or deforms causing the rod of the switch 9 linked to it to move axially assisted by its spring 12 so that the wall 10 closes the corresponding circuit when establishing contact with terminals 11. If the temperature continues to rise, it will be the other capsule 3 that causes, upon melting, the closure of the other switch 9 linked to the explosive charge inside the extinguishing device referenced in this case in general with the number 14 and so that the evacuation of the extinguishing product takes place. The switches 9 therefore belong to respective electrical circuits powered by the battery 13 or connected to any other circuit. In one of them, the alarm device linked to one of the capsules 2 is interleaved. The other circuit, linked to the other capsule 3, has the wires connected to a match 15 which is inserted inside the extinguisher 14, in intimate contact. With the explosive charge.
