Description

Trueno de aviso para pirotecnia.Warning thunder for pyrotechnics.

Object of the invention

La presente invención se refiere a un trueno de aviso para pirotecnia, es decir, a un dispositivo de la clase empleada en los fuegos artificiales y destinado a la generación de un estruendo de gran magnitud a una altura considerable.The present invention relates to thunder of warning for pyrotechnics, that is, to a class device used in fireworks and intended for the generation of a roar of great magnitude at a considerable height.

Field of the Invention

Es el de la fabricación de dispositivos para la generación de fuegos artificiales, con la particularidad de preparar dispositivos de elevado nivel de seguridad.It is the manufacture of devices for the fireworks generation, with the particularity of Prepare high security devices.

Background of the invention

Se conocen diversos tipos de truenos de aviso para pirotecnia, empleados normalmente, de manera preferente, para señalar el inicio y, en su caso, el final de un castillo de fuegos artificiales.Various types of warning thunder are known for pyrotechnics, normally employed, preferably, for signal the beginning and, where appropriate, the end of a castle of fires artificial.

Los truenos conocidos están constituidos normalmente por dos tipos de productos químicos, uno de propiedades oxidantes, tal como el perclorato de potasio, y otros de propiedades reductoras, tal como el aluminio pulverizado o el azufre, de modo que al mezclarse forman un producto potencialmente detonante que, al encenderse por medios provocados, convencionalmente, origina el gran impacto sonoro.The known thunder are constituted normally for two types of chemicals, one of properties oxidizers, such as potassium perchlorate, and others of reducing properties, such as pulverized aluminum or sulfur, so that when mixed they form a product potentially trigger that, when ignited by provoked means, conventionally, it causes the great sound impact.

Los productos en cuestión deben mantenerse aislados uno de otro hasta el momento apropiado para ponerse en contacto y realizar la mezcla deseada, antes de su uso. Para ello, los truenos de aviso deben comportar medios de separación de los productos, contenidos en sendos receptáculos, medios que se eliminarán oportunamente para obtener el resultado buscado.The products in question must be maintained isolated from each other until the appropriate time to get in contact and make the desired mixture, before use. For it, warning thunder must include means of separation from products, contained in two receptacles, media that will be eliminated in a timely manner to obtain the desired result.

Es esencial para la seguridad en el transporte, la separación física de los productos químicos formantes del trueno, y esa exigencia determina la llamada división de riesgo en el transporte.It is essential for transport safety, the physical separation of the chemicals that form the thunder, and that requirement determines the so-called risk division in transport.

El concepto de división de riesgo se tiene en cuenta en el transporte de los productos químicos susceptibles de combustión y explosión, tales como los que integran los truenos de aviso, hasta los lugares de su utilización, definiéndose niveles de riesgo indicados, de mayor a menor, con las designaciones 1.1, 1.2, 1.3 y 1.4.The concept of risk division is held in account in the transport of chemical products susceptible to combustion and explosion, such as those that integrate thunder from notice, up to the places of its use, defining levels of indicated risk, from highest to lowest, with designations 1.1, 1.2, 1.3 and 1.4.

Para conseguir un nivel de seguridad aceptable en orden al transporte debe tenerse la separación fiable entre los dos componentes reaccionantes de los truenos de aviso, separación que, por otra parte, ha de poder destruirse con facilidad en el momento oportuno.To achieve an acceptable level of security in order to transport the reliable separation between the two reactive components of warning thunder, separation which, on the other hand, must be easily destroyed in the opportune moment.

Brief Description of the Invention

En vista de las circunstancias antedichas se ha diseñado un tipo de trueno en el que la separación de los dos componentes de tipo químico previamente a su contacto y consiguiente mezcla se realiza mediante un elemento laminar, tal como un disco, de papel, cartón o plástico de consistencia adecuada para mantener aquellos productos fuera de contacto hasta el momento preciso. Dicho elemento laminar es totalmente fiable, pero puede destruirse con facilidad para permitir la mezcla explosiva de los dos componentes.In view of the above circumstances it has been designed a type of thunder in which the separation of the two chemical type components prior to contact and consequent mixing is carried out by means of a laminar element, such as a disk, of paper, cardboard or plastic of adequate consistency to keep those products out of touch so far precise. Said laminar element is totally reliable, but can destroyed easily to allow explosive mixing of two components

La membrana separadora se monta en posición segura en la carcasa del trueno, definiendo en ésta dos espacios adyacentes, respectivamente ocupados por los componentes químicos en cuestión.The separating membrane is mounted in position safe in the thunder housing, defining two spaces in it adjacent, respectively occupied by the chemical components in question.

Para facilitar la explicación, se acompaña la presente descripción de unos dibujos en los que se ha representado, a título de ejemplo ilustrativo y no limitativo, un caso de realización de un trueno de aviso para pirotecnia, según los principios de las reivindicaciones.To facilitate the explanation, the present description of some drawings in which it has been represented, by way of illustrative and non-limiting example, a case of realization of a warning thunder for pyrotechnics, according to principles of the claims.

Brief description of the drawings

La figura 1 es una sección meridiana de un trueno de aviso del tipo que se describe, con la membrana central separadora de los dos productos químicos antes de su mezcla.Figure 1 is a meridian section of a warning thunder of the type described, with the central membrane separator of the two chemicals before mixing.

La figura 2 representa el mismo trueno de aviso con la incorporación de una carga de elevación y la mecha que permitirá su encendido.Figure 2 represents the same warning thunder with the incorporation of a lifting load and the wick that will allow its ignition.

Detailed description of the invention

Los elementos designados con números en los dibujos corresponden a las partes indicadas a continuación.The designated elements with numbers in the Drawings correspond to the parts indicated below.

El trueno que se describe comprende una carcasa C formante de un contenedor de configuración ventajosamente redondeada (esférica o cilíndrica), de paredes rígidas y hecha, por ejemplo, de un material plástico, constituida preferentemente por dos hemisferios o semicilindros 1 y 2, asociados por sus zonas ecuatoriales mediante un entrante 3 y un saliente 4 en sus bordes.The thunder described comprises a housing C forming a configuration container advantageously rounded (spherical or cylindrical), of rigid walls and made, by example, of a plastic material, preferably constituted by two hemispheres or semi-cylinders 1 and 2, associated by their zones equatorial through an incoming 3 and an outgoing 4 in their edges.
