Definitions

  • the present invention relates to a spray module for a device for fighting a vegetation fire.
  • Another object of the invention is a device for fighting a vegetation fire.
  • the invention relates to a method for combating a vegetation fire.
  • vegetation fires are often also referred to as bush fires, field fires or forest fires and belong to the natural and environmental disasters. Fighting such fires is associated with great dangers for the emergency services and the material used due to a lack of water and/or personnel and terrain that is often difficult to access. The unrestricted spread of such a vegetation fire also endangers human and animal habitats and can lead to life-threatening situations. In addition, critical infrastructure such as power supply lines, power generation systems or substations are often affected.
  • Vulnerable areas typically experience warm climates, with often hot and dry winds, all of which results in parched vegetation that can catch fire relatively easily.
  • the fire can spread by convection, i.e. when combustible material comes into contact with burning material, or by thermal radiation. Strong winds often also promote rapid spread of vegetation fires.
  • a system with several nozzles connected via lines is used, which are deployed in the vegetation threatened by a vegetation fire in order to moisten it.
  • the nozzles are attached to the ground of the terrain and are directed upwards.
  • the nozzles each produce water fountains with a height of more than 5 m. Due to the discharge of the water as at least 5 m high water fountain, it can happen that the water is mainly absorbed in the air and only a small proportion of the applied water contributes to the humidification of the vegetation.
  • the vegetation in the immediate vicinity of the nozzle cannot be sufficiently moistened, so that there is a risk of the nozzle and/or the line connected to the nozzle being damaged by the vegetation fire. Therefore, the probability of containing the vegetation fire is reduced.
  • DE 69402 099 T2 describes a system for generating a spray bell consisting of droplets, which can be used to fight forest fires.
  • the plant consists of several atomization poles placed at a predetermined distance from each other.
  • Each of the atomization poles has a ground-lying T-piece with two opposite ports to which water supply hoses can be connected.
  • a rigid tube is placed at the top of the T-piece, at the top of which is a single diffuser for generating drops. Fastening the entire atomization post in a position that is elevated relative to the ground is neither intended nor practicable.
  • the atomizer pole is supported by one or more support feet.
  • the connection between the T-pieces of different atomizer poles is made via another rigid pipe, which cannot adapt to local requirements.
  • DE 202020 103 781 U1 describes a device for liquid distribution when fighting fires, with a frame for arranging the device on a base and with a feed pipe running vertically upwards from the frame.
  • the lower end of the inlet pipe has a T-piece for connecting two fire hoses.
  • At the upper end of the inlet pipe there is a single spray nozzle which can be rotated about a vertical axis. This device cannot be arranged as a whole in a position that is elevated relative to the ground.
  • the object of the present invention is to increase the probability of containing a vegetation fire.
  • a spray module for a device for combating a vegetation fire comprising: an inlet for a fluid and an outlet for the fluid and a fastening device for fastening the spray module in a position that is elevated relative to a substrate, a first spray mist nozzle with a first opening surface, which is designed to deliver a first spray, and a second spray nozzle with a second opening surface, which is designed to deliver a second spray, wherein the first and the second opening surface are arranged parallel to one another on the spray module such that the the first spray and the second spray can be delivered in two opposite directions.
  • the spray module according to the invention includes both an inlet and an outlet for a fluid, so that the fluid can flow through the inlet into the spray module and a proportion of the fluid that is not released through one of the spray nozzles to the environment through the outlet of the spray module , For example, can be forwarded to another spray module.
  • the fastening device is set up to fasten the spray module at a position that is higher than the ground, which makes it possible to adjust the position of the spray mist nozzles to the height of the vegetation.
  • the spray nozzles are arranged on the spray module in such a way that the sprays emitted by these spray nozzles can be emitted in two opposite directions.
  • a spray mist in particular in the shape of a club, can be generated from a position that is elevated relative to the ground in two directions emanating from the spray module. This can improve the moisture penetration of the vegetation in the direct vicinity of the spray module. The possibility is opened up of generating a line of spray mist parallel to a front of the vegetation fire. In addition, the spray module can be better protected in this way against damage caused by the approaching fire. Overall, this results in an increased probability of stopping the vegetation fire.
  • the first spray nozzle is a flat jet nozzle and/or the second spray nozzle is a flat jet nozzle.
  • Flat jet nozzles are also known as fan nozzles and can create a fan-shaped spray pattern. With such a configuration of the spray module, a fan-shaped spray can be generated by the first spray nozzle and/or the second spray nozzle.
  • An advantageous embodiment of the invention provides that the first spray mist nozzle is arranged on a first side of the spray module and the second spray mist nozzle is arranged on a second side of the spray module opposite the first side.
  • Such an arrangement of the spray mist nozzles enables a compact design of the spray module, with a pressure chamber being arranged in particular between the first and the second spray mist nozzle, via which the fluid to be delivered via the two spray mist nozzles is conveyed to the spray mist nozzles.
  • a preferred embodiment of the invention provides that the spray module has a self-protection nozzle with a third opening surface, which is designed to release a third spray mist, the third opening surface being arranged perpendicularly to the first and second opening surface.
  • the spray module equipped with the self-protection nozzle can be oriented during use such that the fluid is discharged through the first and second spray nozzles substantially in a direction parallel to a fire front and the fluid is discharged via the self-protection nozzle substantially in a direction parallel to the fire front perpendicular to the fire front.
  • the spray generated by the two spray nozzles can form a line parallel to the fire front, and the self-protection nozzle can wet an area between the fire front and the spray module to reduce exposure of the spray module to the fire front.
  • the self-protection nozzle can be designed as a nozzle with a round cross-sectional opening or as a flat jet nozzle.
  • the inlet and the outlet are arranged coaxially to a virtual fluid axis and the third opening surface of the self-protection nozzle is arranged parallel to the virtual fluid axis.
  • a virtual fluid axis of the spray module can be defined at the outlet, along which the fluid essentially flows from the inlet to the outlet.
  • the virtual fluid axis can be arranged to run in a direction perpendicular to the fire front. If several spray modules are connected to one another, the fluid can be guided along the virtual fluid axis parallel to the fire front from a first spray module to an adjacent, second spray module.
  • the fluid can be released via the first spray mist nozzle in a first direction, which runs counter to the direction in which the fluid flows into the spray module. Further, the fluid may be discharged via the second spray nozzle in a second direction corresponding to that in which the fluid exits the spray module through the outlet.
  • the fastening device is arranged on a side of the spray module opposite the self-protection nozzle.
  • Such an arrangement of the fastening device on the spray module has the advantage that the fastening device can be arranged on a side of the spray module that faces the approaching fire front is turned away. The risk that the fastening device will be damaged by the fire front or that an element interacting with the fastening device, in particular part of the vegetation or a mount, will be affected by the fire front can therefore be reduced.
