This has a linearly adjustable penetrating tool for penetrating a cell structure and introducing an extinguishing agent into an interior of the cell structure through the tubular penetrating tool, which is conductively connected to an extinguishing agent tank on. The linear drive of the penetrating tool takes place by means of prestressed spring arrangement to achieve a high impact velocity of the penetrating tool on the cell structure, in order to achieve penetration. A measure facilitating the process in the known device is to apply a defined contact force of the penetrating device to the cell structure in order to achieve a pre-tension before the penetration process. The document is also shown in place of the spring drive for the Penetrierwerkzeug as a linear drive can be acted upon with a pressure medium pressure cylinder.

The storage of Penetriervorrichtung and the projector on the device carrier allows by means of drives an independent relative adjustment between the Penetriervorrichtung with Penetrierwerkzeug and the launcher to optimally bring the required each application device for the application in position and without disturbing influence by the other device, but also order Damage to the device not required to avoid. For this purpose, the device has a first motor for the adjustment of the launcher from a first position to its second position and a control and monitoring device, by which a mutual movement influence of the two devices is prevented.

From another document, US 7,055,613 A , a fire extinguishing device on a boom system of an emergency vehicle is known, which consists of a quenching medium conducting penetrating device. The penetrating device is arranged in a profile carrier, which is pivotally mounted in an end region of the cantilever arm and which supports a tubular penetrating tool linearly adjustable. The penetrating tool is fed with the extinguishing medium and its end portion is designed for piercing a wall and also forms a nozzle head. The arrangement of the Penetrierwerkzeuges within the joint arm mounted on the pivoting and pivoting support profile allows optimal alignment of a direction of action of Penetrierwerkzeuges in view of the geometric conditions of a wall to be penetrated and also with regard to the optimization of the angular position between the boom and the line of action of Penetrierwerkzeuges to reduce the reaction forces occurring during the penetration process on the boom.

This object of the invention is achieved in that with the return line at least one further pressure accumulator element for intermediate storage of the pressure medium is fluidly connected and that the at least one first accumulator element is arranged upstream of the extension movement causing pressure chamber of the pressure cylinder.

The advantage here is that so by the provision of the at least one further pressure storage element for the intermediate storage of the pressure medium, a braking effect in the extension movement of the penetration tool, by otherwise in the relatively long return line flow resistance is prevented. This makes it possible to keep the dimensioning of the return line low. Furthermore, as for the extension movement of the Penetrierwerkzeuges provided for the extension movement pressure chamber directly a large volume of the pressurized pressure medium without significant line losses available.

In principle, it is advantageous if a protruding end of the penetrating tool is designed as a mandrel-shaped nozzle head with radial outlet openings for the extinguishing medium. In this way, an optimization of Penetrierwerkzeuges is achieved in terms of penetration and application of the extinguishing medium for an effective deletion process.

Also advantageous are the embodiments described in claims 2 and 3, whereby verbal information exchange is achieved.

It is also possible, however, an advantageous embodiment according to claim 4, whereby the mission force or the operator on a control unit, for example on a control panel with screen, an overview of the situation in the interior of a room cell is created, thereby achieving an effective and rapid deployment to mitigate damage becomes.

However, an embodiment according to claim 5 is also advantageous, as a result of which information is available to the operational force for assessing the environmental conditions of persons to be rescued and trapped in a room cell, and that subsequently measures for mountain rescue can be coordinated.

Also possible is an embodiment according to claim 6, whereby an additional illumination in the vicinity of penetrated into the room cell Penetrierwerkzeuges is achieved.

Due to the advantageous embodiments described in claims 7 and 8 a small held in its dimensions penetrating tool is achieved, whereby the force application is minimized for a penetration and lower reaction forces acting on the deployment device and an adjustment of the camera between a retracted position during a Penetriervorganges and a advanced position to achieve a sufficient viewing environment is achieved.

Finally, however, embodiments according to claims 9 and 10 are advantageous, whereby a simple operation and a simple operation and also data records for a subsequent analysis without affecting activities of an operator can be achieved.

For a better understanding of the invention, this will be explained in more detail with reference to the embodiments shown in the figures.

In the 3 and 4 another embodiment of the extinguishing device 1 is shown. In the following description, the already existing and described in the preceding figures components, the existing terms and reference numbers used.

In the end region 2 of the extension arm 3, a plate-shaped bracket 45, which projects beyond the erecting plane 18 of the extension arm 3, is arranged as the device support 16, which protrudes over a profile extension 46 into a hollow profile 47 forming the extension arm 3 and is rigidly secured. The plate-shaped bracket 45 supports at opposite side surfaces 48, 49 the launcher head 5 with the launcher pipe 6 and the penetrating device 8 with the pressure cylinder 35 with the hollow penetrating tool 9 formed as a piston rod 36. The launcher head 5 and the penetrating device 8 are each in bearing assemblies 50, 51, the lifting shaft 17 forming, which extends to the righting plane 18 at a right angle, pivotally mounted. Independent lifting drives 52, 53 ensure independent pivoting of the thrower head 5 and the penetrating device 8 for aligning their longitudinal central axes 23, 30 in the erecting plane 18 or in the plane 44 extending parallel thereto.

A lifting drive 52 is in the illustrated embodiment, e.g. a at an underside 54 of the cantilever arm 3 e.g. However, as further shown, a rotary drive 56 is also possible, e.g. a hydraulic motor, electr. Servo motor etc. directly in accordance with double arrows causes a stroke adjustment of the projector head 5 and / or the penetrating device 8 about the lifting axis 17. The pressure cylinder 55 is supported via a bearing block 57 relative to the boom arm 3 and is mounted on the piston rod side on a steering lever 59 of the thrower head 5 or the penetrating device 8.

The launcher tube 6 is further, as already described above, rotatably mounted in the pivot bearing assembly 26 about the axis of rotation 17 perpendicular to the axis of rotation 27 and by means of the rotary drive 28 on the launcher head 5 - according to double arrow 29.

The bypass line 69 connects the pressure line 67 directly to the pressure chamber 63 while a preferably remotely controllable control valve 70 is provided for the supply of the pressure chamber 64 in the supply line 68. Through this line and valve arrangement, the pressure chamber 63 is acted upon directly with the operating pressure while the pressure chamber 64 is acted upon by the control valve 70 optionally with the medium pressure. From the pressure chamber 64 outgoing leads a return line 71 via a still described in detail control and regulating device for the discharge of the medium in the tank 65th

The penetrating tool 9 or the piston rod 36 is formed in the pressure chamber 63 causing the extension movement of the penetrating tool 9 with a diameter 72 which is greater than a diameter 73 in which the retraction movement causing pressure chamber 64, resulting in different Kolbenwirkflächen 74, 75 and This results in generally upon application of both pressure chambers 63, 64 with the same medium pressure, an adjustment of the Penetrierwerkzeuges 9 in the retracted end position, which is limited by a piston stroke, by a the piston movement surface causing the extension movement resulting restoring force due to the area ratios of the piston effective surfaces 74, 75th

In this case, the control valve 70 is in a switching position, which establishes a line connection between the pump 66 and the pressure chamber 64, while the further pressure chamber 63 with the pressure medium supplying bypass line 69 forms a direct connection from the pump 66 to the pressure chamber 63.

The control valve 78 has a large flow cross-section in order to achieve a rapid expansion of the pressure chamber 64 and at least one further pressure accumulator element 79 is provided in addition to the flow connection to the return line 71 for a temporary storage of the medium. Thus, a braking effect in the extension movement of the penetrating tool 9, caused by a flow resistance in the relatively long return line 71, prevented and allows to keep the dimension of the return line 71 low.

To effect an extension movement of the penetrating tool 9, the control valve 70 arranged in the supply line 68 between the pump 66 and the retraction movement 64 is switched to a blocking position and the control valve 78 at the outlet 77 of the pressure chamber 64 is moved to an open position and the pressure chamber causing the extension movement 63 on the one hand with the pressure medium from the immediately upstream accumulator element 76 plus the medium flow of the pump 66 acted upon.
