Abstract
The object of the present invention is to provide a new installation for fighting fire which is improved over known installations for such units which have a hydraulic system. According to the invention, the hydraulic system is arranged to be driven with water as drive medium, and preferably at least a part of sprinklers or spray heads intended for fighting fire are connected to the power source of the hydraulic system via the pressure line of the hydraulic system. Earlier required double pipe systems and double power sources are no longer necessary; the same system can be utilized for fire fighting as well as for numerous regular hydraulic functions e.g. in a tanker.
Description
Installation for Fighting Fire The invention relates to an installation for fighting fire, for a unit provided with a hydraulic system, such as a ship.
In e.g. different kinds of ships a number of important regular functions are performed by means of a hydra ulic system for which oil has been used as the drive medium. A separate installation has been used for fighting fire.
An object of the present invention is to provide a new installation for fighting fire which is improved over known installations for such units which have a hydraulic system.
The installation according to the invention is mainly characterized in that the hydraulic system is arranged to be driven with water as drive medium, and that sprinklers or spray heads intended for fighting fire are connected to the power source of the hydraulic system.
In one specific embodiment there is provided a hydraulic system in a unit, the hydraulic system driving regular hydraulic functions of the unit and including a drive medium, a power source for driving the drive medium, and a pressure line and a return line for conducting the drive medium through the hydraulic system; wherein the drive medium is water and the hydraulic system further includes sprinklers or spray heads connected to the power source via the pressure 1a line and optionally the return line, the sprinklers or spray heads utilizing the water of the hydr a ulic system as a fire-extinguishing medium and being adapted to fight fire in the unit, whereby the hydraulic system can be utilized for the fire fighting as well as for the r a gular hydraulic functions of the unit.
The concept water here of cour se includes certain additives, e.g. anti-corrosion additives. The powe r source of the hydraulic system is usually a hydra ulic pump having a high operating pre ssure and a high volume capacity. The pump is in t urn usually drive n by a main power source, such as an electric generator.
In a preferred embodiment of the invention, at least a part of sprinklers or spray he ads intended for fighting fire are connected to the power source of the hydraulic system via the pressure line of the hydraulic system.
Some sprinklers or spray he ads can in addition be connected to the return line of the hydraulic system, in which case it, when activating the sprinklers or spray heads, is reason t o close the WO 94/01I79 ~ ~ PCT/Ft9~/0028'=

return line after the last sprinkler or spray head, in order to maintain a sufficient pressure in the return line.
Thanks to the invention, earlier required double pipe systems and double power sources are no longer necessary; the same system can be utilized for fire fighting as well as for numerous regular hydraulic functions a.g. in a tanker. In addition to considerable savings in installation hardware and installation work, a comparatively great reduction in weight is achieved; the last-mentioned advantage is of surprising significance in ships o~ high speed.
In some cases it may be of advantage to connact at leash a part of the sprinklers or spray heads 'to the power, source of the hydraulic system through own lines separate from the lines of the hydraulic system:
In such an embodiment the separate fire fighting hydraul~.cs can be utilized for performing certain additional functions essential when a fire has started, such 'as closing fix°e doors,: driving el~vatc~rs etc. If the regular main power source, usually an electric generator, would fall off at a fire, an emergency generator, often having less power than the 2.5 regular generator, is capable of providing sufficient power for fighting the fire and for perforying at least a limited number of additic~n~l important fhnctians;, the regular hydraulic system can then possibly be disconnected altogether.
The inventive idea can widely be said to be that the same syate;n is utilized both for firm fighting and'for more or less regular hydraulic functions.:
Hydraulic' sys ems in ships and the like generally have a ha.gh aperating pressure, 100 bar or' mo=e. It is recommendable to use such sprinklers or spray heads which are presented, e.g. in Canadian Patent Applications 2,104,302 and 2,103,069 and are capable of operating at a high pressure, provide effective fire extinguishing with small amounts of water and can be made to produce concentrated fog-like sprays having a good penetrat ion power.
Installing such sprinklers or spray heads for connection to hydraulic systems here in question is considered to fall within normal skill in the art and is therefore not described in more detail in the present patent application.
In a tanker the installation f or fighting f ire can be utilized for spraying a fog of water droplets, having a typical diameter size of 30 to 150 microns, into the oil tanks for fire extinguishing and cool ing, respectively.
Although the invention mainly is intende d to be used in ships and other units directly compar able thereto, the invention can also be utilized in other units as well. Steel plants and mining can be mentioned as examples.
