Description

[0041] Further advantages, features and details of the invention are elucidated on the basis of a preferred embodiment thereof, wherein reference is made to the accompanying drawing, in which:

[0042] FIG. 1 shows a view of an extinguishing system according to the invention.

[0043] Extinguishing system 2 is utilized to combat fire source 4 (FIG. 1). Extinguishing system 2 is here provided with pump 6, which during use is arranged in waterway 8 and is driven using drive system 10 with power pack 12. Pump 6 is provided with inlet 14 for supplying water from waterway 8. Pump 6 is further provided with extinguishing conduit 16 which in the shown embodiment is split via manifold 18, optionally provided with valves 20, 22, into extinguishing conduits 24, 26 to first nozzle 28 and second nozzle 30.

[0044] Extinguishing system 2 is further provided with a controller 32 for directly or indirectly controlling pump 6. In the shown embodiment controller 32 is operatively connected to extinguishing controller 34. Controller 32 is optionally integrated with extinguishing controller 34. Extinguishing controller 34 can receive information via the input 36 into database 38 and/or input 40 via input device 42 of user 44. In the shown embodiment input device 42 is a mobile application.

[0045] In the shown embodiment extinguishing system 2 is provided with two (optional) sensors 46, 48 with which information can be received via measuring signals 50, 52 by extinguishing controller 34. Measuring signals 54, 56 are also optionally provided for the purpose of transmitting valve positions and/or valve controls of valves 20, 22 from and to extinguishing controller 34. If desired, additional sensors 58, 60 which provide information via measuring signals 62, 64 to extinguishing controller 34 can be provided close to pump 6 on the input side and output side. As addition or alternative to sensor 60, pressure probe fitting 61 can be provided for a pressure measurement, for instance a control and/or additional input data via measuring signal 65 to extinguishing controller 34. Sensors 46, 48, 58, 60, 61 can be diverse types of sensor, for instance suitable for measuring pressure and/or flow. Pump data 66 can likewise be provided to extinguishing controller 34. On the basis of the obtained and/or already available information extinguishing controller 34 can send settings or control commands 68 to controller 32, and optionally send them via control signal 70 to pump 6.

[0046] In the case of source of fire 4 extinguishing system 2 is carried to the desired position. Pump 6 is placed close to a waterway 8. Powerpack 12 with drive 10 is placed on ground surface 72. User 44 provides information 40 to extinguishing controller 34 via input 42, for instance in the form of a mobile application. Extinguishing controller 34 can here likewise make use of information 36 coming from database 38. On the basis hereof extinguishing controller 34 makes in combination with information of pump data 66 and the specific situation in respect of a number of nozzles 28, 30, as well as extinguishing length L, a determination of the operating pressure on the side of nozzles 20, 30. The effect of extinguishing system 2 on source of fire 4 can hereby already be determined beforehand in effective manner and, if desired, be set using control signal 68, 70.

[0047] Possible changes in the situation can be obtained by an update of pump data 66, user data 40 and data coming from measuring signals 50, 52, 54, 56, 62, 64, 65. If desired, it is also possible to have user 44 adjust the current setting of for instance operating pressure for pump 6 via operating buttons 74, 76. An effective and efficient extinguishing system 32 is hereby utilized for the purpose of combatting source of fire 4. When the combatting of source of fire 4 has finished, user 44 can deactivate extinguishing system 2 by means of operating buttons 74, 76 and/or input system 42, after which extinguishing system 2 can be cleared away and be put in storage and/or utilized at a different location.
