description

The invention relates to a ordnance clearing device with a detonator that can be set up near a stored ordnance with a charge to destroy the ordnance.

Unexploded ordnance, such as mortar cartridges, grenades or mines, is to be rendered harmless in the field. According to the prior art, plastic explosives with an appropriate detonator are used for this. Cables must be laid in the field. This is cumbersome. AT-PS 355 478 describes a further proposal of this type, wherein a hollow charge is used instead of plastic explosive.

The object of the invention is to propose a weaponry clearing device of the type mentioned at the outset, which is of simple construction and also functions reliably when several weapons are cleared.

According to the invention, the above object is achieved by the characterizing features of patent claim 1.

The ordnance disposal facility is constructed without electrical components. No electrical energy supply is necessary and there is no risk of electromagnetic interference.

The explosive ordnance clearing device described is safe, since it is only when the central clock is plugged in and the ignition device is adjusted relative to the central clock that a pre-release takes place and the timer is activated.

It is advantageous that the central clock can be removed after the ignition device has been set - before it is ignited - and used to set further ignition devices. For safety reasons, the central clock cannot be adjusted against the downward direction during the process.

If a site is to be cleared in which there are several unexploded ordnance, then a tripod with a detonator and a charge directed at it is set up for each unexploded ordnance. The central clock is first wound up manually, for example to 60 minutes, after which it begins to run down. Then the first igniter is set with the central clock. It adjusts to the remaining time that has not yet elapsed on the central clock until the time of setting. If, for example, 5 minutes have passed between the winding up of the central clock and the setting of the first igniter, the first igniter is set to 55 minutes. The first igniter is then removed and the second igniter is set using the central clock. If, for example, another 10 minutes have passed by then, the second igniter is set to 45 minutes.

In good time before the time originally set on the central clock has elapsed, it emits an acoustic signal so that the blaster can go to safety. After the time has elapsed, the detonators then ignite the unexploded ordnance at a predetermined, identical time.

US Pat. No. 2,982,209 describes an explosive device for destroying electronic devices, the ignition mechanism of which contains a clockwork. When the ignition mechanism is activated, the explosive charge is ignited after a predetermined period of time. This explosive device is built into the electronic device.

Further advantageous embodiments of the invention result from the dependent patent claims and the following description of an exemplary embodiment. The drawing shows:

An igniter (1) has a housing (2) to which a shaped charge (3) can be attached. The igniter (1) can be attached to a tripod (4). A central clock (5) can be coupled to the igniter (1).

Provided in the housing (2) as an ignition chain is an ignition needle (7) loaded with a spring (6) and in a rotor (8) a detonator (9) and an ignition transmitter (10) which is associated with the shaped charge (3). A torsion spring (11), the other end of which is arranged on an elevator wheel (50), acts on the rotor (8) provided as securing means. The shaft (12) is rotatably mounted in the housing (2). A rotatable safety bolt (13) is provided to secure the rotor (8).

A barrel (14) is attached to the shaft (12), on which a spiral spring (15) engages, which is attached to the shaft (12). On the outside of the barrel (14), a toothing (16) is provided, in which a timer (17) engages. The timer (17) has a plurality of gear wheels (18) and an anchor escapement (19) (cf. FIGS. 4 and 6). A locking segment (20) is coupled to one of the wheels (18) and engages with a shoulder (21) on the rotor (8). The blocking segment (20) is designed such that it releases the rotor (8) about 5 minutes to 10 minutes before the ignition.

An edge (22) is formed on the barrel (14) with an incidence slot (23). This is assigned a drop-in lever (24) which holds back a release lever (25). The release lever (25) and the drop lever (24) are mounted on a shim (26). The trigger lever (25) retains the ignition needle (7) in the position shown. Then the device enters the slot (23) to the lever (24)

this pivots into that and thereby releases the release lever (25), so that the firing needle (7) is then free.

The shaft (12) is provided with a profile (27) as a coupling means at its end projecting beyond the housing (2). The securing bolt (13) has a similar profile (28). A stop (29) is provided on the housing (2) as a coupling means.

The central clock (5) (Fig. 7 to 9) has a housing (30). An elevator shaft (32) carrying an elevator button (31) is mounted on this. The elevator shaft (32) engages a coupling shaft (34) via gearwheels (33). A barrel (35) with a spiral spring (36) is arranged on the elevator shaft (32). The barrel (35) is coupled via a toothing (37) to a timer (38) which has wheels (39) and an anchor escapement (40). An acoustic signal transmitter (42) can be actuated by means of a further gear train (41).

An insertion space (43) for the igniter device (1) is formed on the housing (30). The coupling shaft (34) projects into the insertion space (43), the end of which is provided with a segment (44) in accordance with the profile (27). The coupling shaft (34) is surrounded by a guide sleeve (45) in the insertion space (43). In addition, a pin (46), which faces the profile (28) of the securing bolt (13), projects into the insertion space (43).

The functioning of the described device is approximately as follows:

In the starting position, the central clock (5) has run out. The coupling shaft (34) stops in an end position. The acoustic signal has expired and the barrel (35) is still under residual tension. It is not possible to couple the ignitor (1).

By means of the elevator button (31), the barrel (35) and the acoustic signal generator (42) are drawn up in the central clock (5) in accordance with the intended running time, which is, for example, a maximum of 60 minutes. The coupling shaft (34) is then in a stop position. The central clock (5) starts running immediately after being wound up.

The housing (2) of the igniter device (1), which is still being secured, can now be inserted into the plug-in area (43). The profile (27) of the shaft (12) then engages in the correct position on the segment (44) of the coupling shaft (34). The stop (29) of the housing (2) is pushed through the opening (49) and then engages in the annular groove (47). The width of the stop (29) fits into the openings (49) or into the annular groove (47). With a remaining running time of less than ten minutes, for example, the position of the segment (44) in the guide sleeve (45) is such that the shaft (12) or its profile (27) and thus also the stop (29) with the opening (49) is no longer axially adaptable.

in the secured position of the igniter (1), the firing needle (7) is held back by the release lever (25). The rotor (8) is pivoted and blocked in this position by the safety bolt (13). In addition, it is also blocked by the extension (21) of the blocking segment (20). The barrel (14) 'is not wound. The torsion spring (11) is relaxed.

The igniter (1) is then rotated about the axis (A) until the stop (29) of the housing (2) hits the end stop (48). The igniter (1) is then removed from the central clock (5). The following happens during rotation:

The shim (26) with the drop lever (24) and release lever (25) rotates according to the angle of rotation, whereby the running time is set. The barrel (14) with the spiral spring (15) is wound up. The torsion spring (11) is tensioned with the elevator wheel (50). During rotation, the pin (46) moves past the profile (28) of the securing bolt (13), causing it to twist so that it pre-unlocks the rotor (8).

Then the timer (17) starts. The trigger lever (25) still blocks the firing needle (7) and the rotor (8) is initially still blocked by the blocking segment (20). About 5 minutes to 10 minutes before the end of the running time, the blocking segment (22) releases the rotor (8) so that the torsion spring (11) pivots it into the arming position.

At the end of the term, the drop slot (23) of the barrel (14) is next to the drop lever (24) so that it pivots into the drop slot (23) and thereby releases the release lever (25). The ignition needle (7) is now struck by the spring (6) on the detonator (9), so that the shaped charge (3) is ignited.

The running time to which the dial (26) is set when the igniter (1) rotates with respect to the central clock (5) depends on the time that has elapsed since the central clock (5) was pulled up. If the central clock (5) is initially set to a running time of, for example, 60 minutes and elapses, for example, 10 minutes until the ignition device (1) is opened, then the dial (26) is easily set to the remaining running time of 50 minutes.

The central clock (5) emits an acoustic signal in good time before the end of the running time, for example 10 minutes before the end. It is then also no longer possible to couple an igniter (1) to the central clock (5), since its coupling shaft (34) with its segment (44) is already rotated so far that the housing (2) of the igniter (1) can no longer be inserted into the insertion space (43) because the position of the shaft (12) with its profile (27) no longer permits this.

When clearing several unexploded ordnance in the area, the procedure is as follows:

A tripod (4) is set up for each dud. The central clock (5) is then wound up. A selected hollow charge (3) is then attached to an igniter (1) for each stand (4). The igniter (1) is set by means of the central clock (5) in the manner described and then fixed on the stand (4) and aligned with the dud.

The same then takes place with the other tripods with the same central clock.

re sets runtime than with previously installed. A few minutes before the end of the running time, the central clock (5) emits an acoustic signal, so that the personnel installing the explosive ordnance clearing device take themselves to safety. At the end of the term, the shaped charges ignite essentially simultaneously.

The igniter (1) can of course not be attached exclusively to a tripod (4), but can of course also be fixed in some other way. Thus, it can also be determined for the targeting of a weapon to be disposed of on or in the earth area, for example if mines covered with earth have to be removed.
