Description

Device for controlled electric detonation

This invention is referring to a controlled electronic wired detonation device, which is used for the destruction of ammunition, of missiles, mines and plants in general. The controlled electronic detonations are handled by staff of the Hellenic Army and not only. By this method they destroy, a large number of useless ammunition, missiles that were found or did not exploded, mines that were rescinded, and are inactive due to withdrawal, or have to be destroyed on the spot at a minefield. They are also used for several tactics in an operation period, but also in plants in general.

The detonations are separated according to the volume, of the control, and of the selection of focal points: into common, with the use¹ of common cap, and of slow burning detonating rope, which is lighted with a lighter or matches and are non-controllable, and to electrically firings, with the use of a bipolar wire which is connected to an electrical cap, which is set off from a dynamo- exploder, are controlled, and the testing of the circuit is checked with a galvanometer. The controlled electric detonations can be done wireless via a transmitter and a receptor. However, due to the rapid growth of technology, the possibilities of unintentionally use and intersection are increased, while it is advisable for limited cases and only at points where the cables are not able to reach. At the common detonation we do not have the control and the time frame to prepare more that 2 focal points, due to limited time for lighting the detonating rope. At the controlled electric wired detonation, a safe space is selected, that has distance at least 90 metres from the focal points. For each focal point separately a bipolar cable of knitted independent poles is unfolded, that due to the big distance that is extended for safety reason, is tangled during the outstretching but mainly at he enlacement with its adjacent and often is cut from the detonation, with result the testing of the circuits and the detonations to become time-consuming and laborious. The testing of the caps and of the circuits are done by galvanometer. The firings are operated from a safety distance with dynamo-exploder, that is connected with a bipolar cable. The other end of each cable is connected with the electric cap which is placed to the explosive material in order to end at the material that is to be distracted that are at the focal points. Due to the fact that the cables have the same color and specifications inter se, it is impossible to recognize each focal point in order to do the testing of the circuit or the detonation, with result the cables to be used separately for each use, the number of the focal points with each circuit, and the order of choice to be impossible.

According to the concretisation of the invention, the devise of the controlled electric detonations, is wired, every function is controlled from the control table, and includes: 10 switches of choice with lid, with the possibility of the desirable detonation line, the simultaneous detonation of a part, or even of all the focal oints, the trial of circuits and avoidance of involuntary of inadvertently use. It also includes, operation switch that is activated with a key, which is extracted for exclusive and secure use only by the chief, the plug that is connected with a cable in order to do the test of the circuits and of the caps with galvanometer, that has an incorporated dynamo-exploder for the detonation of the focal points and an alternative operation switch for the testing of the circuits or the activation of the detonations. The switchboard is connected through plugs to the corresponding 12polar extension cable that ends up to the pivot. The pivot is placed at a safety distance that has been selected, it is constituted from a metal base, the metal pivot that is on it, and the central cable of the 12pole that is wrapped to the metal pivot. The central cable is unfolded toward the focal points at a safety distance that is extended to 220 meters, the 10 out of its 12 poles correspond to the 10 choice switches with lid and to the 10 on part cable of the bifurcation cable. The other 2 poles connected, create a circuit in each one of the 10 poles separately. The central cable is connected via plug, with the corresponding from the bifurcation cable, to which end up 10 on part bipolar cables that approach the focal points, and bifurcate according to the provision that is selected. In each connection for the circuit testing or the detonation preparation, one end of the central cable and the other end of the extension cable are connected respectively to the bridge connecters, while they are connected to one another via plug of the extension cable that has no connectors, with the corresponding of the central cable that is found incorporated in the metal pivot. By this way probable electrostatic and electromagnetic charges from the use of mobile phones or magnetic fields are avoided. It is thus ensured with the possibilities of the device: The number of detonations with the preparation of a single connection, the control as well as the choice of each focal point from the control board, the speed since there are no tangled and cut cables while the folding and unfolding of the central cable from the pivot is also done rapidly, the facility from the immediate transport of the device, from the plain handling to the control board and of the connection by plugs on part of pieces from each other, and finally security is ensured via wired operation, the switch with the key that is extracted, the central cable that is extended to a big distance and of the bridge connectors. The bifurcation cable with the 10 pairs approaches a lot the focal points, while if a simple bipolar cable is added the deterioration is avoided. It is used with the following provisions: a. Ventalia, mainly for the firincj range where there are no predetermined focal points. b. Vertical, reaching at both sides in each mine-beam it meets, following the mine-strip trace for destruction of mines on the spot, at predetermined spots inside the minefield. c. Opening up a corridor in the minefield, penetrating vertically the mine- rows in the depth meaning, with predetermined focal points and d. Free, for all kinds of destruction in plants and operations in general, in no predetermined points. The preferred concretization of the device is with 10 detonation focal points that can be increased with the addition of more poles in the central cable, bigger number of bipolar cables at the bifurcation cable, bigger of more plugs and bridge connectors.

The invention is described further down, with the help of examples and the report to the attached drawings at which: Figure 1 shows a ground plan of the control board (10) were all the consisted parts of the device are shown. The control board (10) is connected with the rest of the device through the extension cable (12) and is operating either as a circuit tester, or as an energy source for the detonations. It includes an aluminum box (15) on the bottom of which have been laid out: The bipolar male plug (16) in which the corresponding female bipolar flush plug (17) of the test circuit cable (11) is inserted, as it is shown in figure 2, the 17pole female plug for the chassis (21) that locks with flush connection through spiral metal ring, with the corresponding 17-pole male (22) that is at the extension cable (12) as it is shown in figure 3, the alternative operation switch ON/OFF (23) for the segregation of use, the switch (24) that is activated with the key , the operation key (25), the dynamo-exploder (26) that includes the two poles (18) and (19) with the indicative red lamp (27), which is ON after a continues press of the left button (28), and release a momentous voltage of 450 Volt with the press of the right button (29). Finally in order are placed the selection switches with lid (30), (31), (32), (33), (34), (35), (36), (37), (38) and (39), that when are shut down, they drift and restore their lid in the OFF position.
