Definitions

  • the invention relates to a lance, in particular an extinguishing lance for firefighting, by means of which at least one additive can be dispensed together with the pressurized fluid.
  • the EP 2 168 636 A1 describes equipment for making openings in a surface of an object and supplying a fluid into a space through the previously formed opening.
  • This equipment includes a pressure source for supplying a pressurized fluid, a lance with a nozzle assembly, and a line between the pressure source and the nozzle assembly for supplying the pressurized fluid from the pressure source to the nozzle assembly.
  • the pressurized fluid flows essentially in the form of a jet from the nozzle arrangement onto the surface, wherein an additive contained in a vessel can be entrained by a pressure difference built up by the pressurized fluid in the nozzle arrangement.
  • the nozzle arrangement has a first nozzle, a second nozzle and an intermediate chamber between the first and second nozzles.
  • the pressurized fluid flows into the first nozzle and leaves the nozzle arrangement through the second nozzle.
  • At least one inlet or several inlets open into the intermediate chamber of the nozzle arrangement, each inlet being connected to a line or a pipe which is connected to a vessel containing the respective additive, or in the case of several inlets, each connected to different vessels are.
  • An actuating means for a valve is provided at each inlet in order to release or prevent the respective supply of the additive into the intermediate chamber.
  • the actuating means are arranged directly on the nozzle arrangement at their respective inlets.
  • the additive which acts as an abrasive, can be supplied via an inlet to the intermediate chamber.
  • an extinguishing foam or an extinguishing powder can be fed to the nozzle arrangement via this, although this is also only possible after the valve has been opened and is drawn into the intermediate chamber of the nozzle arrangement by the fluid under pressure and together with the fluid in shape a fine mist is ejected from the nozzle arrangement.
  • the IT VI20 120 326 A describes a lance with spaced apart first and second handles, wherein the lance can be used to extinguish fire.
  • a first valve arrangement in the area of the first handle, the supply of a pressurized fluid can be released or prevented.
  • a control valve is provided in order to be able to selectively supply the pressurized fluid to a first pipe arrangement and/or a second pipe arrangement running parallel thereto.
  • the second handle is in turn mounted on the first tube arrangement with its handle end so that it can be pivoted from a position closer to the operator to a position further away from the operator. With the second handle, the fluid jet to be dispensed from the first pipe arrangement can be adjusted with its respective spray cone.
  • the fluid can be fed to an inner channel in order to release a concentrated jet of fluid from the first pipe arrangement. If the second handle and a control valve connected to it are pivoted, the fluid is fed to an outer channel surrounding the inner channel and a fluid jet with a larger cone angle is emitted.
  • the lance includes at least a first handle that can be grasped by an operator and at least one first channel with a first inlet and a first outlet that can be fluidly connected to a first supply line of a pressurized fluid.
  • the lance further includes a first control lever that acts on the at least one first channel to enable an operator to control the selective inflow of the pressurized fluid therethrough.
  • At least one second channel is provided with a second inlet and a second outlet, which can be fluidly connected to a second supply line of an abrasive powder.
  • a second control lever acts on the at least one second channel to enable an operator to control the selective flow of abrasive therethrough.
  • a first nozzle has a pair of first inlet openings each fluidly connected to the first outlet and the second outlet.
  • a Venturi effect mixing means is used to mix the pressurized fluid and the abrasive powder while selectively activating the inflow thereof through the second channel.
  • a first outlet opening is for spraying a concentrated Jet of the mixture of the pressurized fluid and the abrasive powder is provided.
  • the at least one first handle includes the first and second control levers, the control levers being arranged close together to enable the operator to operate the first control lever and the second control lever with the same hand that grips the at least one first handle. This lance has generally proven itself in use, but when wearing protective gloves it was often difficult to be able to selectively operate the control levers located immediately adjacent to it.
  • a cleaning device for cleaning objects that can be applied individually and/or with a mixture of water, compressed air and chemical agents for the purpose of cleaning.
  • a mixing and metering block is provided, which has feeds for the individual cleaning components and a version for discharging the cleaning components in individual or mixed states.
  • a single adjustable means is arranged between the feeds and the execution, which is suitable for releasing all supplied components in a mixed, isolated or metered manner or for blocking at least one of these components.
  • the object of the present invention was to overcome the disadvantages of the prior art and to provide a lance which can be easily and safely operated by a user in order to be able to control the optional delivery of the additive with just one hand and to do so independently from the operation of dispensing the fluid.
  • the lance according to the invention is preferably used to extinguish a fire in firefighting operations, whereby an access opening must first be created through a solid body, such as a wall, a wall part, a body part, a battery or the like, in order to allow the pressurized fluid, usually water, to be able to use or introduce fire fighting in the space behind the solid body.
  • a solid body such as a wall, a wall part, a body part, a battery or the like
  • an additive in particular a solid granulate or another cutting agent, is added or mixed into the pressurized fluid and this mixture is applied together by means of the lance to the point at which the access opening is to be produced.
  • the advantage achieved in this way is that with a simple adjustment movement of the second adjusting means of the second adjusting means arrangement, the flow through and suction of ambient air into the mixing chamber of the first nozzle body is selectively controlled and thus subsequently the admixture of the first additive to the one under pressure Fluid is enabled or prevented.
  • the flow through or suction of the first additive through the second channel starting from the first container into the mixing chamber is determined by the release or closing of the own and independent third channel in the area of the second actuating means arrangement.
  • the first handle of the lance is held with one hand and the first actuator arrangement is also operated with the same hand. This also prevents unintentional operating errors, since the two actuating means arrangements are arranged at a distance from one another in the direction of the longitudinal extent of the lance.
  • the second adjusting device arrangement can be easily and safely operated with the other hand due to the distance from the first handle. In this way, a spatially clear separation of the two adjusting device arrangements is achieved.
  • the at least one first channel and the at least one third channel are arranged or formed in the lance body. This achieves a compact design of the lance body.
  • the second adjusting means arrangement further comprises a control pin, which control pin is mounted on the lance body so that it can pivot about its longitudinal axis.
  • the first channel comprises a first sub-channel and a second sub-channel in its longitudinal section between the second adjusting means arrangement and the first channel outlet, and the first sub-channel is arranged within the second sub-channel.
  • Another embodiment is characterized in that the second channel is formed by its own connecting line and the connecting line is arranged to run outside the lance body or inside the lance body.
  • a further embodiment provides that the second adjusting means of the second adjusting means arrangement is formed by an opening passing through the control pin in the radial direction, in particular by at least one bore.
  • the second adjusting means arrangement further comprises a third adjusting means and the third adjusting means is directly operatively connected to the second channel, the third adjusting means being adjustable from a closed position to a release position and vice versa and thus the Flow of the first additive through the second channel can be directly adjusted.
  • the third adjusting means also works together with the second adjusting means. An opposite control position of the second and third adjusting means is always provided, namely such that when the second adjusting means is in the closed position, the third adjusting means is in the release position and vice versa.
  • a further preferred embodiment is characterized in that the third channel is closed when the second adjusting means is in the closed position and the third adjusting means is in its release position and the second channel is open throughout, or that the third channel is in the release position second Adjusting means is continuously open and the third adjusting means is in its closed position and the second channel is closed. This allows a secure locking or closed position of the second channel to be achieved when the second adjusting means is in the release position. This means that even if the third channel is unintentionally laid, an unwanted removal of the first additive from the first container can be reliably prevented.
  • the second adjusting means and the third adjusting means of the second adjusting means arrangement are arranged spaced apart from one another in the axial direction of the control pin and offset from one another when viewed in the circumferential direction. This means that the extent of the adjustment movement and the associated change in the operating mode of the lance can be achieved depending on the extensive offset.
  • Another embodiment is characterized in that a second nozzle body is provided, which second nozzle body is arranged upstream of the first nozzle body in the flow direction of the pressurized fluid and the first channel outlet of the first channel is arranged or formed in the second nozzle body.
  • a further preferred embodiment is characterized in that the third channel is also arranged or formed in the second nozzle body. This makes it possible to create a safe channel formation for the third channel that is protected from external environmental influences.
  • the first nozzle body of the nozzle arrangement is held removably on the lance body, in particular removably on the second nozzle body.
  • a further possible embodiment has the features that the first sub-channel ends in the axial direction in front of the first channel outlet and opens into the second sub-channel surrounding the first sub-channel and further at least one end section of the first sub-channel is arranged in alignment with the first channel outlet. This can create a straight and central delivery direction of the pressurized fluid from the first partial channel through the first channel outlet and on to the first nozzle body.
  • the second actuator arrangement further comprises an actuator group with at least a first actuator and a second actuator, which actuators of the actuator group are in direct operative connection with the first channel.
  • a further possible and possibly alternative embodiment has the features that the actuating elements of the group of actuating means are each formed by an implementation that penetrates the control pin in the radial direction, in particular by at least one bore. This also makes it possible to create a compact and trouble-free adjustment device for controlling the fluid throughput.
  • a further embodiment provides that the actuating elements of the actuating means group are arranged at a distance from one another in the axial direction and, viewed in the circumferential direction, are arranged circumferentially offset from one another by an offset angle and optionally only one of the actuating elements allows the flow of the pressurized fluid. This can ensure a safe separation of the supply of fluid into the respective sub-channel.
  • a further embodiment provides that the first actuator of the actuator group is in direct operative connection with the first sub-channel and the second actuator of the actuator group is in direct operative connection with the second sub-channel. This ensures a clear assignment of the respective actuator to the respective sub-channel.
  • Another alternative embodiment is characterized in that when the second actuating means is in the closed position, the third channel is closed and at the same time the flow connection between the first channel and the first sub-channel is formed by means of the at least one first actuator and further by means of the second actuator the flow connection between the first channel and the second sub-channel is interrupted. Due to the respective control position of the second actuating means in relation to the actuating elements of the actuating means group, a full jet of fluid can be achieved in this control position together with the first additive to be dispensed.
  • the third channel is continuously open when the second actuating means is in the release position and at the same time the flow connection between the first channel and the first sub-channel is formed by means of the at least one first actuating element and further the flow connection between them by means of the second actuating element the first channel and the second sub-channel is interrupted.
  • this specified control position enables the delivery of a full jet of fluid without the addition or admixture of the first additive. If a further container with a further additive is also provided and the further container is in flow connection with the third channel via the second adjusting means, the additive stored there can be sucked in simultaneously from both the first container and the second container. In this operating state, the pressurized fluid is also released from the lance with a full jet.
  • the third channel is closed and at the same time the flow connection between the first channel and the first sub-channel is interrupted by means of the at least one first actuator and further by means of the second Actuator, the flow connection between the first channel and the second sub-channel is formed.
  • a further container is provided for a further additive to be accommodated therein and the further container is in flow connection via a fourth channel with the second adjusting means arrangement and further with the third channel.
  • a separate container opening must also be provided for sucking in the additional additive in order to enable ambient air to flow in and be sucked into the container interior.
  • Another alternative embodiment is characterized in that at least one of the containers is held removably on the lance body. This means that the container or containers can be easily and quickly refilled or replaced during ongoing use.
  • a further possible alternative embodiment is characterized in that a pivoting arrangement is provided, by means of which pivoting arrangement at least the first container is pivotally held on the lance body. This means that the container or the respective containers can be aligned relative to the lance body in such a way that the suction point is always at the position closest to the ground.
  • a further possible and possibly alternative embodiment has the features that at least one container opening is provided, which at least one container opening opens into a container interior of the container. This allows ambient air to flow into the interior of the container. Otherwise, a negative pressure would build up in the interior of the container due to the suction effect exerted on the additive.
  • a further embodiment provides that the container interior is in flow connection with the external environment via the container opening and at least one filter element is arranged in the container opening.
  • the filter element Depending on the choice and design of the filter element, an unintentional inflow of dirt, dust particles, the previously released additive and/or air humidity can be reduced or completely prevented.
  • a possible alternative embodiment is characterized in that at least the further container is provided and the second adjusting means arrangement further comprises the third adjusting means, with the second adjusting means arrangement being in a first operating position the third actuator and the first actuator of the actuator group are each in their release position and the second actuator is in its closed position and the third channel is closed, and the first actuator of the actuator is in a second operating position of the second actuator arrangement. Group and the second adjusting means are each in their release position and the third adjusting means is in its closed position and the second channel is closed.
  • the additive is selected from the group of solid granules, abrasive agents, extinguishing powders, extinguishing additives, foaming agents, dry ice, and decontamination agents. This allows a high degree of variation to be created for a wide variety of purposes and operating conditions.
  • the term is used directly or indirectly for the effect of the actuating means or the group of actuating means on the respective channel.
  • the term is to be understood directly as meaning that the respective actuating means or one of the actuating elements of the actuating means group itself physically acts on the channel connected to it and enables or prevents the flow or the flow through of the respective medium.
  • the term indirect is to be interpreted in such a way that the respective actuating means or one of the actuating elements of the actuating means group is physically operatively connected to one of the channels and enables or closes the flow or the flow through of the respective medium in the respective channel, but depending on the operating position The flow or flow through of another medium is also enabled or prevented in another of the channels.
  • a lance 1 or its individual components is shown, which can also be referred to as an extinguishing lance.
  • Such lances 1 are used, for example, in fire brigade operations to fight fires in which initially no access to the source of the fire is possible because the room is closed or enclosed by walls.
  • at least one access opening must be formed through the wall.
  • a pressurized fluid such as water, is used to fight fires or fires. It is known to mix or add at least one additive 2 to the pressurized fluid.
