Definitions

  • the invention relates to portable handheld fire extinguishers and has a fire extinguisher working with water under high pressure to the subject.
  • the filling quantities are between 2 and 12 kg.
  • a blowing agent is carbon dioxide or nitrogen in these extinguishers used.
  • the extinguishing agent consists of dry powder or from film-forming foam extinguishing agent.
  • extinguishers are designed for one-time use. Refilling the extinguishers after use can only be carried out by specialist companies. The minimum service life depends on the extinguisher size and is a maximum 15 seconds. With powder extinguishers, the extinguishing effect is Choked the fire. But because the source of the fire is there is not cooled, the fire source often reignites instead of.
  • Fire extinguishings of fire class B are also known portable carbon dioxide extinguishers that are often used to extinguish Fires in electrical systems, data processing systems, Laboratories, etc. are available and fill quantities between 2 and have 6 kg.
  • extinguishing effect from suffocation of fire and these extinguishers are only for once Designed for use and can only be used by Specialist companies can be refilled.
  • a newer water extinguishing device from DE 44 43 111 A1 known as the portable fire extinguisher with the Features of the preamble of claim 1 formed is. So it consists of a pressure-proof closed water tank and a pressurized gas bottle that can be connected to the outside, to the contents by opening the compressed gas cylinder valve pressurize and expel the water tank. With the water tank is more about a dimensionally stable Hose connected to a nozzle from which the extinguishing water The compressed gas is sprayed out of the gas bottle.
  • this known extinguishing device has the disadvantage that it only is designed for single use and after use can only be refilled by specialist companies, because for connection the gas bottle and the hose is used in the known Water extinguisher a container head that is firmly in a Opening of the container is screwed in and refilled of the water tank is not permitted by the user.
  • a fire extinguisher that is no longer portable but can be rolled as a water extinguisher is known from US Pat. No. 2,832,425, in which on a rack a water tank and a separate carbon dioxide container are arranged. The outlet of the carbon dioxide tank is through a pipe to the inside of the water tank connected to this with pressure act on, and also both the water tank as well as the carbon dioxide container each with its own Hoses connected to a common spray gun. Also in this known fire extinguisher is after the empty spraying refilling the water tank on site and Position not provided by the user and not possible.
  • the object of the invention is to be as universal as possible portable fire extinguisher to create that after use by the user quickly for reuse can be retrofitted.
  • the fire extinguisher according to the invention works with water, so that the extinguishing effect from both suffocating and cooling Effect is achieved. Cooling will reignite of the fire source once extinguished with extensive Avoided security.
  • the fine atomization has the advantage that with small amounts of water have a great extinguishing effect and with it the risk of water damage as a result of Deletion is significantly reduced.
  • Extinguishing with water in atomized form namely by Splashing water from a water tank with propellant under it high pressure from an atomizing nozzle is in itself known, for example from DE 44 43 111 A1.
  • This publication speaks of spraying the water with a pressure of at least 50 bar with a water content of 12 liters, which in view technically hardly on the necessary pressure resistance of the container appears understandable.
  • this well-known fire extinguisher corresponds to the well-known concept described above portable fire extinguishers designed for single use, namely up to the consumption of the filling quantity of the extinguishing agent container, are designed.
  • the concept according to the invention differs from this fundamentally by refilling this as often the extinguishing agent container, i.e. the pressure-resistant water container, by the user during a delete operation through the separate water filling opening that serves as a refill opening enables.
  • the extinguishing agent container i.e. the pressure-resistant water container
  • the fire extinguisher according to the invention can easily be refilled.
  • a used pressure bottle can easily be replaced by a new pressure bottle so that the deletion process by refilling the extinguisher on the spot can be continued several times.
  • carbon dioxide extinguishers and the like are unique Use, the deletion process should not be successful been, or should there be reignition at the source of the fire, a continuation of the deletion is no longer possible.
  • a portable fire extinguisher according to the Invention from a portable water tank 1 with a water filling opening which can be closed by a closure 2, one using a standard quick connector with the water tank connectable and arranged on the outside of this Pressurized gas bottle 3, a rigid tube 4 and one Spray gun 5.
  • the water tank 1 is designed as a pressure-resistant container. Its filling quantity is, for example, approximately 12 to 16 l Water.
  • the compressed gas bottle 3 can be filled with ordinary air his.
  • the pressure in the compressed gas bottle is preferably at least about 200 bar.
  • the compressed gas cylinder shows in usually a shut-off valve that is only used of the fire extinguisher is opened so that the pressurization of the water tank 1 only takes place in the application.
  • the outlet pressure of the extinguishing water is then preferably at least between about 25 and 35 bar.
  • the hose 4 connected to the water tank connects the water tank with the spray nozzle 5.
  • the spray nozzle 5 is trained so that they have a finely atomized water jet generated.
  • the nozzle can be designed with an adjustment facility to widen the beam wider or narrower bundle, but in any case to form a Aerosols in finely atomized form emerge from the nozzle.
  • the Water tank 1 can be filled up quickly and by coupling a new compressed gas cylinder is ready for use again be transferred. If necessary, can also, enough Compressed gas capacity provided a compressed gas bottle for Expelling 2 or more water fillings can be used.
  • Fig. 2 shows the fire extinguisher according to the invention in a schematic Form designed as a portable fire extinguisher. It otherwise corresponds to the embodiment according to FIG. 1.
  • Fig. 3 shows a variant of the fire extinguisher according to the invention in a rollable version.
  • the fire extinguisher either mounted on a trolley 6 or with one Wheelbarrows can be integrated, in the latter Case the water tank is firmly connected to the trolley frame is.
  • This variant has the advantage that something Larger amounts of water with a correspondingly stable pressure-resistant Execution of the water tank can be provided because the weight of the rollable device is not that important plays.
  • the term "portable fire extinguisher" used here should also be such a relatively light mobile Execution include.
