Abstract

Explosion-controlled radio extinguisher characterized in that it comprises a radio remote detonation mechanism that is incorporated into an explosion extinguisher. (Machine-translation by Google Translate, not legally binding)

Description

Explosion extinguisher controlled by radio.

Object of the invention

The present invention, as indicated in the statement of this specification refers to a fire extinguisher of explosion used in firefighting, especially in the forestry field, to which the wick has been replaced by a remote detonation mechanism by means of a module radio.

The interface between remote control and extinguisher is implemented by electronics, which receives radio signals sent by a remote control, processes them, and operates a mechanism of ignition that detonates the powder contained in the extinguisher.

Background of the invention

Explosion extinguishers are a tool for fire fighting, especially forestry. This method in extinguishing forest fires is very useful for the control and extinction in the early stages of the fire avoiding so that fire increases in size which would mean a higher economic cost by having to mobilize motor pumps, helicopters and even extinction planes. Also in phases after the forest fire, when the affected land is very steep and it becomes difficult to arrive with a motor pump or other means terrestrial

They consist of a container, usually plastic cylindrical containing powder and water with liquid retarding A forestry specialist places her on the ground in the fire front Gunpowder is detonated by a wick of just over a meter in length that is launched towards the front of Call to be turned on. Once the wick has been thrown, the specialist has about two seconds to get away from the explosion extinguisher to prevent damage.

The main problem of this system is the safety: the forest specialist or operator has very few left seconds from throwing the wick until the fire extinguisher does explosion to get away with the consequent danger that this entails. In addition, the exact moment of the explosion, very important for the extinguisher is completely effective, it cannot be chosen with too much precision since it will explode only when the wick garment.

There are currently numerous variants of patents and utility models of remote detonators but none of them applied to an explosion extinguisher, nor with a selector mechanism that allows several fire extinguishers to be detonated at once and / or by groups if desired.

Description of the invention

The device of the invention has a mode detonation of the extinguisher by remote control. The interface between Remote control and extinguisher is implemented by electronic, which receives the radio signals sent by a device remote control, processes them and triggers an ignition mechanism that it detonates the powder contained in the extinguisher.

This invention has the following advantages: on the one hand it allows on the one hand to activate a group of extinguishers all at once needing only one person, and for another the greatest security you have when exploding fire extinguishers from a distance much greater than that of a few meters that Allows the classic fire extinguisher.

There is a mechanism for the fire extinguisher to explosion "learn" and store the remote control by which it will be exploited preventing another radio control from exploiting the extinguisher. Learning continues to be stored although electronics of the extinguisher is off.

For the explosion extinguisher to perform said Detonation must first be armed and a short time must pass (it propose 5 seconds) for security reasons. For more security it is proposed that once this time has elapsed, emit a beep with a buzzer so that the operator realizes that this extinguisher can Already be detonated. The explosion extinguisher can also be new disassembled and disconnected in case it is no longer required its detonation

As already mentioned, this mechanism allows exploit several fire extinguishers at once, but as functionality additional is added exploit them by groups once armed and placed in the fire: in each fire extinguisher they can be selected numbers, as many as numbers are in the radio control (it propose 3); if the number chosen in it matches the number chosen in the extinguisher, it will explode, but will not do so if not match the number even if the fire extinguisher is armed.

Brief description of the drawings

To complement the description that is being carried out and with the purpose of helping a better understanding of invention, is attached to the present specification, as part member of it, a descriptive drawing and two planes with electronic schemes, in that order:

Description of a preferred embodiment

One of the possible realizations of this invention according to the figures described above consists on two different printed circuit boards with their corresponding components connected by a cable as it is shown in figure 1. The first of these plates (1) comprises the electronics shown in figure 2. Said circuit board printed will contain the light emitting diodes to inform the user status (7, 10) and push buttons for control (4, 5, 9). On the back it will contain the low charge battery that will feed the two plates (13). This board will be joined by a 14-pin cable to the other board (2) through a connector located on both plates (3). The cable will follow the path of the old wick The plate (2) is the one that will contain the electronics represented in figure 3 and will contain the control electronics and the connector to the detonator (14).

The reason for the separation of the system into two halves is as follows: plate (1) needs to be in the surface of the extinguisher since it has to be handled by a person while the plate (2) must have a temperature that does not exceed the temperature range of commercial components (se they use this type of components for reasons of cost) so one of the ways to protect it is to introduce it inside Fire extinguisher The plate (1) contains components that, in case of high temperature, would not affect the detonation control, a Once the extinguisher is ready to be exploded.

The detonator (14) is connected to the plate (2) and consists of a low resistance metal (aluminum or tungsten) in contact with gunpowder. When a current is passed to Through metal, it heats up and explodes gunpowder. At If using aluminum, it is convenient to use a drop of phosphorus in contact with gunpowder and aluminum to help in the deflagration

The part of the electronics that comprise the radio control will be located on the connector (12) of the board (2), while the antenna (11), consisting of a flexible cable of 17 cm will be on the plate (1) so that from outside.

The electronics must first be activated with the button (4), once this is done you can make the fire extinguisher programmed so you know what remote control they are going to be exploited or erase memory. This memory is permanent although disconnect the explosion extinguisher.

The learning and deletion process is given by the radio control device In the case of learning the process It is as follows:

1. Press the programming button (9) briefly.

2. The learning light emitting diode (10) is will illuminate.

3. Press a button on the remote once. Diode Light emitter (10) will turn off.

4. Press a button on the remote again. Diode light emitter (10) will flash for 10 seconds approximately.

5. Once the light emitting diode (10) leaves If the control flashes, it will be ready to operate that extinguisher.

In the event that a fire extinguisher does not want to be detonated with a particular command you can proceed to delete the memory. The steps are these:

1. Press and hold the programming button (9) for at least 10 seconds.

2. Release the button. Light emitting diode It will flash while the radio module erases its memory.

In a second phase, during the extinction of the fire, the electronics will be activated again with the button (4) for, once the extinguishers are placed in the desired place, choose a number with (6) from 1 to 3 (if the button is not pressed by default 1) is selected, number that will be indicated by the diodes light emitters (7). This choice of number will be useful in the case that they want to exploit the extinguishers in groups as explained in the "Description of the invention" section.

Then the fire extinguisher is armed with button (5) and after 5 seconds the extinguisher will be ready to be detonated by remote control, when this is so a buzzer (8) emits an audible signal noticeable to the operator.

The detonation occurs when you press one of the 3 remote control buttons if the pressed button matches the number chosen in the extinguisher.
