IPC: A62C3/02
Filed: 2001-06-22
Abstract: 1. A fire extinguishing system (10) for dousing a fire including a conduit (11) for extending in the space and for delivering a fire extinguishing liquid (18) to the space, a track (20) extending in a longitudinal direction of the conduit (11), pump means (24) adapted to move on the track (20) and adapted to pump liquid (18) delivered to the conduit (11), drive means (28, 29) adapted to move the pump means (24) along the track (20), control means (33) for controlling movement of the pump means (24) relative to the track (20) characterised in that there is provided a through (12) for receiving liquid (18) from the conduit (11), the through (12) are provided with a plurality of walls (15) forming a series of compartments (16) in the trough (12), at least one of the compartments (16) is provided with a connecting member (13) for communicating a compartment (16) with the conduit (11), at least one of the connecting members (13) is provided with a valve (i4) for controlling the flow of liquid (18) from the conduit (11) to a compartment (16) and the pump means (24) is provided with an inlet (26) that can either be moved to an inoperative position such that the pump means (24) is able to move unobstructed from a compartment (16) to another compartment (16) and so on until it is near a compartment (16) that is close to the fire, or that can be moved to an operative position entering the liquid (18) that has been transferred from the conduit (11) in the compartment (16) close to the fire such that the pump means (24) can pump the liquid (18) from that compartment (16) and douse the fire. 2. A fire extinguishing system as claimed in claim 1 characterised in that each of the compartment (16) is provided with sensing means (17) for sensing whether level of liquid (18) in the corresponding compartment (16) is at predetermined level. 3. A fire extinguishing system as claimed in any one of the preceding claims characterised in that the control means (33) includes video means and a video camera mounted on the pump means (24). 4. A fire extinguishing system as claimed in any one of the preceding claims characterised in that the track (19) is located on one side of the through (12). 5. A fire extinguishing system as claimed in any one of the preceding claims characterised in that the drive means (28, 29) is electrically operated and includes a shoe (30) adapted to engage a conductor rail (23). 6. A fire extinguishing system as claimed in any one of the preceding claims characterised in that the pump means (24) is linked with a remote control station by electromagnetic radiation at least on part of the way. 7. A fire extinguishing system as claimed in any one of the preceding claims characterised in that the nozzle (25) is movable in order to direct the jet of water or foam onto the fire. 8. A fire extinguishing system as claimed in any one of the preceding claims characterised in that there is provided a source of light for lighting the scene. 9. A fire extinguishing system as claimed in any one of the preceding claims characterised in that the inlet (26) adapted to enter into liquid (18) is fixed. 10. A fire extinguishing system as claimed in any one of the preceding claims characterised in that there is provided an arm affixed to the pump means (24) and extending in different directions than the track (20), the nozzle (25) of the pump means (24) being movable along the arm. 11. A fire extinguishing system as claimed in claim 10 characterised in that there is provided a second track at some distance of the system and a carriage is provided that move on that track and that end of the arm that is not affixed to the pump means (24) lays on that carriage.
