Definitions
- the invention relates to an extinguishing lance for firefighting, with a fastening unit for attaching the extinguishing lance to a wall and with a penetrating unit having a piston and a blade for penetrating the wall, the fastening unit having a connecting surface for supporting it on the wall, the penetrating unit having at least one blade for penetrating the wall and is arranged in a cylinder so as to be displaceable along a main direction of movement between a starting position and an end position, with at least one propellant supply line being flow-connected to the cylinder for introducing propellant along the main direction of movement, with an extinguishing agent supply line and the penetration unit being flow-connected to one another in the end position are.
- the invention further relates to a method for fighting fires on an object, preferably a battery, in a housing, with an extinguishing lance being supported on a bearing surface, preferably the housing, via a connecting surface of the extinguishing lance, a penetrating unit of the extinguishing lance using a propellant from a starting position in the direction of the Housing is moved to an end position, a blade of the penetrating unit at least partially penetrates the housing, and an extinguishing agent is passed over the penetrating unit into the housing.
- WO 2020/206482 A1 discloses such an extinguishing lance, with several fixing columns being arranged on a flange around the penetrating unit, by means of which the extinguishing lance can be fastened in the vehicle or in its surroundings.
- the fixing columns are pivoted about the joints on the extinguishing lance and the distal ends of the fixing columns are thus brought into contact with a surface opposite the housing. There they wedge, so that the extinguishing lance is clamped between this surface and the housing.
- WO 2021/146763 A1 discloses an extinguishing lance which has no propellant but in which the penetrating unit is moved by means of the pressurized extinguishing agent. Although this requires simpler handling, since only one agent has to be provided, it is disadvantageous for the function, since it is very difficult to permanently provide the extinguishing agent in sufficiently high pressure, so that the penetration unit can be driven through the housing and the holding of the Penetrating unit is not secured in the end position.
- a rigid support element is arranged at the end opposite the connecting surface, which can be supported, for example, on the vehicle headliner.
- the support element is pivoted about a joint on the extinguishing lance until the vehicle headliner is reached and the extinguishing lance is thus wedged between the vehicle floor and the vehicle headliner.
- a single support element means easier handling and quicker assembly in the vehicle. It is just as problematic, however, since the oblique position of the support element that results in this way entails the risk of the extinguishing lance tipping away to the side.
- the object of the invention is therefore to provide an extinguishing lance that enables safer extinguishing.
- the extinguishing lance has, at its end opposite the connecting surface, a length-adjustable fixing device for support on a wall or other object, which is connected to the fixing unit.
- At least one fixing device which is arranged on the end of the extinguishing lance opposite the connecting surface and which is connected to the fastening unit is lengthened at least until it supports the extinguishing lance on a wall or other object .
- the design at the opposite end of the extinguishing lance ensures that the extinguishing lance can be designed as slim as possible and handling is therefore very easy. This is particularly advantageous if the extinguishing lance is to be arranged very quickly when the battery is already on fire.
- the length adjustability means that the fastener does not have to be tilted to bring it closer to the supporting wall or object. This avoids an unsafe fixing and prevents the extinguishing lance from tipping away due to oblique wedging.
- the blade In the starting position, the blade is on the side of the wall on which the extinguishing lance is arranged and is usually arranged predominantly or completely in the cylinder. In the end position, the penetrating unit at least partially penetrates the wall.
- the fixing device is telescopic. This enables a space-saving and simple design of the fixing device, which makes length adjustment possible.
- the fixing device has at least one fixing arm, which is preferably telescopically adjustable in length from a base body of the fixing device. This is a simple and narrow design, which simplifies handling. Preferably only one locking arm is provided. Alternatively, several fixing arms can also be provided, which particularly preferably have parallel longitudinal axes.
- the fixing device is length-adjustable essentially parallel to the main direction of movement and/or is essentially immovable transversely to the main direction of movement. This ensures that the forces transverse to the main direction of movement are minimal when the penetrating unit moves and that the fixing device cannot yield to such a force either. This reduces the risk of tipping over. This is particularly advantageous because it is possible that the two surfaces between which the extinguishing lance is clamped are not parallel to one another or are uneven. This would encourage tipping, but this is prevented by the rigid design perpendicular to the main direction of movement.
- the fixing device is arranged essentially coaxially to the main direction of movement of the penetrating unit, along which the penetrating unit can be displaced.
- At least one fixing arm is preferably arranged essentially coaxially to the main direction of movement of the penetrating unit, along which the penetrating unit is displaceable.
- the fixing device is pretensioned in an extended position, preferably by means of at least one spring. This also applies if a suspension biases the locking device into an extended position.
- the extinguishing lance has an elongate main body which accommodates the penetrating unit at one end and is designed as a guide for the fixing arm at the opposite end.
- This compact design enables a particularly small extinguishing lance that can be easily arranged in or on the vehicle.
- the fixing device has a locking device for locking a main extension length in at least one position in at least one direction. This can prevent the length of the fixing device from being changed unintentionally, in particular from being shortened after it has been arranged on the housing.
- Position means in particular a length adjustment of the mooring device, especially of the mooring arm.
- a locking device prevents the change in the main extension length of the fixing device in at least one position in at least one direction and preferably prevents the fixing device from being shortened after it has been lengthened.
- Locking in at least one direction means that the length of the fixing device during locking is prevented in at least one direction, ie at least shortening and/or lengthening.
- the locking device has a backstop, which prevents the fixing device from moving back into a shorter position and preferably has at least one pawl.
- the fixing device can be quickly extended and the extinguishing lance can be fixed in place without the extinguishing lance being subsequently undesirably released due to the shortening of the fixing device.
- the fixing device is mechanically, hydraulically or pneumatically adjustable in length.
- the extinguishing lance has to be connected to as few supply lines as possible and use is therefore particularly simple and quick, it can be provided that the extinguishing lance has a propellant tank, preferably a pressurized fluid container and/or a hydraulic tank, which is connected to the propellant supply line.
- a propellant tank preferably a pressurized fluid container and/or a hydraulic tank, which is connected to the propellant supply line.
- the piston In order to ensure safe extinguishing, provision can be made for the piston to delimit a chamber in the cylinder which is designed to be flow-connected via a connection to an opening in the piston, the opening being the penetrating unit and an extinguishing agent supply line are flow-connected to one another in the end position and that when extinguishing agent flows in, the chamber is filled with extinguishing agent and the extinguishing agent acts on the piston in such a way that the penetration unit with the piston is essentially held in the end position. This ensures that the extinguishing agent can continuously penetrate the housing after penetrating it.
- the extinguishing lance has at least one handle, preferably on the end opposite the connecting surface.
- the system has lashing points to attach the system to the vehicle with chains or similar.
- the flow connection between the cylinder and at least a part of the propellant supply line can be separated via at least one solenoid valve.
- This is a simple and safe solution for delivering the propellant at the right time.
- the extinguishing lance preferably also has an energy store, particularly preferably a battery, for actuating the magnetic valve.
- the fixing device has a support device for non-slip connection to a surface, preferably a support plate, at its end remote from the penetration unit.
- Batteries are usually installed in the vehicle floor. If the battery catches fire after the vehicle has been in motion, it is particularly advantageous if the extinguishing lance is placed in the cabin of a vehicle and the connection surface is supported on the floor of the cabin and the fixing device is supported on the vehicle headliner.
- the battery is usually arranged in its housing below the floor of the cabin.
- the headliner or the vehicle roof is opposite the floor of the cabin and therefore offers the ideal support surface for the extinguishing lance.
- the extinguishing lance according to the invention enables quick and safe use regardless of the position of the vehicle. It is thus ensured with the extinguishing lance according to the invention that both a parked vehicle and a vehicle that has had an accident can be extinguished quickly and safely.
- FIG. 1 shows a perspective view of a first embodiment of an extinguishing lance according to the invention
- FIG. 2 shows a second embodiment of an extinguishing lance according to the invention in a perspective view.
- the first embodiment of an extinguishing lance 1 according to the invention shown in FIG. 1 has an elongate, essentially cylindrical main body 2 which is designed as a fastening unit 3 at one end and has a connecting surface 4 for resting on a wall such as a housing of a battery.
- the fastening unit 3 has a cylinder inside, in which a penetrating unit can be moved along a movement axis B and can be moved along the movement axis B in the direction of movement R in order to penetrate the wall, so that it protrudes through an opening in the connecting surface 4 and the wall pierces.
- a fixing unit 5 is arranged on the end of the main body 2 opposite the connecting surface 4 , a base body 6 of the fixing unit 5 preferably being designed in one piece with the main body 2 .
- the fixing unit 5 has a fixing arm 7 which extends coaxially with the movement axis B and can be extended telescopically from the base body 6 .
- a main extension length L of the fixing unit 5 is thus adjustable.
- the fixing arm 7 is telescopic with two coaxial arm parts 7a, 7b arranged one inside the other and is guided in the base body 6 along the movement axis B.
- the fixing arm 7 is essentially immobile with respect to movements transverse to the movement axis B through the base body 6 .
- the fixing arm 7 has a support device 8 in the form of a support plate, which preferably has a non-slip surface and particularly preferably a non-slip coating.
- the fixing arm 7 has a plurality of openings along its length. After the extension of the fixing arm 7, a pawl, for example designed as a spring-loaded pin, can engage in at least one of these openings 9, which prevents the fixing arm 7 from moving back into the base body 6 and thus a shortening of the fixing arm. After the deletion has been completed, the locking arm 7 can be retracted again by manually releasing the pawl.
- a pawl for example designed as a spring-loaded pin
- An extinguishing agent supply line 10 is arranged on the outer wall of the main body 2, via which the extinguishing lance 1 can be supplied with extinguishing agent. It guides the extinguishing agent into the end area of the main body 2, on which the connecting surface 4 is arranged. When the penetrating unit reaches its end position in which it penetrates the housing, the extinguishing agent can flow into the penetrating unit and penetrate through the resulting opening through the housing wall into the interior of the housing and extinguish the battery.
- a propellant tank 11 which is connected to the cylinder above the penetrating unit via a propellant supply line 12 and a solenoid valve.
- Fig. 2 shows a second embodiment very similar to the first embodiment. Therefore, only the most important differences are discussed here. Functionally identical components are provided with the same reference numbers.
- the embodiment shown has a support device 8 which has two support units 13 13 .
- These support units 13 can be firmly connected to the support device or can also be designed to be movable. For example, they can be brought into a transport position brought into the area of the main body 2 and/or placed against the main body 2 .
- these brackets serve as a bearing surface for support, on the other hand, they can also serve to improve handling, especially during positioning thus fulfilling the function of a handle.
- the extinguishing lance 1 can thus be easily brought into position and held while the fixing device 5 is being extended.
- the locking arm 7 is fully retracted in the position shown.
- the support units 13 are designed as brackets, but other designs may also be possible. In addition, only one or more than two support units 13 can also be provided.
