Definitions

  • the present invention is aimed at the technological sector of explosives used in mining activities, civil works and in quarries, and refers more particularly to a device capable of adapting in situ to the primer of an explosive accessory for its initiation or activation.
  • safety fuses are conventionally known for the initiation of the fire of an explosive. These safety fuses have the drawback that they generate high levels of contamination when they are turned on and, in addition, they have generated countless accidents in mining activities over time.
  • both electrical devices and safety fuses have the drawback that, being in a single package integrated with the explosive accessory, they can also cause fatal accidents due to explosion during handling, storage, and manufacturing. and/or in their transport, making it also necessary to keep them under strict restrictions of use and legal regulations.
  • the electrical adapter device for the initiation of explosive accessories object of this invention was developed, which being of the type that comprises an ignition stub which receives electrical energy from a power source through some electrical conductors to activate it, it is characterized in that it is adaptable and can be coupled in situ with the explosive accessory and because it also comprises a casing that covers the ignition bead to keep it protected from external agents that can damage it and a cover that can be coupled with the casing which houses to a blasting cap of the explosive accessory, providing protection to it, creating a cavity inside it that brings the ignition heel and the blasting cap of the explosive accessory into contact.
  • the casing and the cover have housing portions for the ignition stub and the primer, respectively, and connecting portions that allow them to be held together.
  • the geometries of said caps have similar cross-sections, at least in the housing portions thereof, so that they can be coupled to each other, one inside the other.
  • the union of said casing and cover can be made by pressure or union members can be provided in at least the union portion of the same that allow to better ensure their assembly.
  • the ignition stub is well known to those skilled in the art, so further details of its operation will not be given, and together with the electrical conductors they allow the circuit to be closed when the power supply is connected.
  • Said ignition stub can be activated from 1 volt, so the power source can be a commercial power source or a common 1.5v alkaline battery.
  • the beneficial effects of the present invention with respect to the state of the art are that it does not generate pollution to the environment, when activating electrically and on the other hand, it allows its transport, handling, storage, manufacturing and/or transport safely, as it is not in a single package integrated with the entire explosive accessory, but is adaptable to its installation on site.
  • FIGURE N° 1 An exploded plan view of the electrical adapter for activating explosive accessories according to the preferred embodiment of the invention is shown, showing the casing partially decoupled from the ignition stub.
  • FIGURE N° 2 An exploded plan view of the electrical adapter for the activation of explosive accessories of figure 1 is shown, showing the coupling of the casing that covers the heel of ignition and a common primer of the explosive accessory.
  • FIGURE N° 3 An exploded plan view of the electrical adapter for the activation of explosive accessories of this invention is shown, showing the coupling of the cover in the common primer of figure 2.
  • FIGURE N° 4 A plan view of the electrical adapter for the activation of explosive accessories of this invention is shown, showing its complete coupling in a common primer of the explosive accessory.
  • FIGURE N° 5 A perspective view of the electrical adapter for the activation of explosive accessories of figure 4 is shown, with a longitudinal section showing the manner of complete coupling with the explosive accessory in the cap of said accessory.
  • the electrical adapter device for the initiation of explosive accessories of the present invention will be implemented according to a preferred embodiment with reference to figures 1-5.
  • the electrical adapter device (100) for the initiation of explosive accessories of this invention comprises an ignition stub (102) which receives electrical energy from a power source (not illustrated) through electrical conductors ( 101) to activate it.
  • the ignition heel (102) has a casing (103) that allows it to be protected from external agents that may damage it, in addition to being perforated through its longitudinal axis, allowing the passage of electrical conductors (101).
  • the casing (103) that allows housing the primer (200) of the explosive accessory, providing protection to it, and said casing (103) and cover (104) create a cavity inside it that puts the ignition stub (102) and the blasting cap (200) of the explosive accessory in contact.
  • the casing (103) and the lid (104) have cylindrical geometries with a circular cross-section, where the casing (103) has a housing portion (103A ) where the ignition stub (102) is housed with an external surface similar to the internal surface of a housing portion (104A) of the cover (104) where the primer (200) is housed, and said housing portions (103A , 104A) are interlockable, one inside the other. Also, the casing 103 and the cover 104 have joint portions 103B and 104B, respectively.
  • connection in said connection portions (103B, 104B) is carried out by pressure between said portions, however, connection members can be provided that allow better ensuring the assembly, for example, including threaded structures said joint portions (103B, 104B).
  • the casing (103) and the lid (104) are made of high-resistance, waterproof, antistatic plastic material.
  • Ignition stub 102 is well known to those skilled in the art. In general, it consists of a pair of thin aluminum films insulated in its central part with a plastic plate where each aluminum film is welded to the terminals of an ignition filament, preferably made of tungsten, and together with the electrical conductors ( 101) allow to close the circuit when the power supply is connected.
  • Said ignition stub (102) can be activated from 1 volt, so the power source can be a commercial power source or a common 1.5v alkaline battery.
  • the electrical adapter (100) receives electrical energy through the electrical conductors (101) from the power source, this energy reaches the ignition stub (102) which activates the spark in the primer (200) of the accessory explosive.
  • the primer (200) is not part of the device but that the installation is done in situ and, in figures 3 to 6, the coupling of the adapter with said primer is shown. As can be seen in figures 3 to 5, when the adapter is installed, a cover (104) is attached that serves to protect the primer (200).
