Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4: a kind of indoor dry powder Intelligent fire extinguishing system, described fire extinguishing system comprises a fixed mount 1, the eminence (as in ceiling) that this fixed mount 1 is disposed in the interior, fixed mount 1 is provided with lifting motor 2, the output of this lifting motor 2 is connected with lifting tooth 3 by gear driving pair, lifting tooth 3 then can with lifting screw 4 coaxial rotation, on lifting screw 4, cover has the crane 5 matched with its screw thread, the lower end of crane 5 is provided with rotating disk 7, this rotating disk 7 is controlled by electric rotating machine 6, rotating disk 7 is provided with infrared thermometer 8, infrared ambulator 9 and telescopic spray nozzle 10, wherein telescopic spray nozzle 10 is interconnected by pipeline and dry powder reservoirs 11, dry powder reservoirs 11 is then connected with high pressure nitrogen storage tank 12, the first magnetic valve 13 is provided with between telescopic spray nozzle 11 and dry powder reservoirs 11,
Above-mentioned telescopic spray nozzle 10 comprises an expansion link 18 be fixedly supported in rotating disk 7, the two ends of this expansion link 18 are smooth shaft, middle part is provided with thread segment, this thread segment matches with the worm gear being arranged on telescope motor 20 working end place, the polished rod port ons of expansion link 18 tail end is supported on support bar 19, the end head of expansion link 18 front end is then connected on jet hose 22 by bulb 21, the material that jet hose 22 adopts rubber etc. that elastic deformation can occur is made, spring 23 is had, for restricting the deflection of jet hose 22 at jet hose 22 overcoat;
The pipeline at above-mentioned dry powder reservoirs 11 two ends is also respectively arranged with a first high pressure hand-operated valve 14, dry powder reservoirs 11, first magnetic valve 13 and the first high pressure hand-operated valve 14 be a composition dry powder memory cell jointly, a dry powder memory cell can be set in each room, if the area in room is larger, also can arrange multiple dry powder memory cell, all dry powder memory cell are arranged between telescopic spray nozzle 10 and high pressure nitrogen storage tank 12 all in parallel;
And high pressure nitrogen storage tank 12 is seated on an adjustable base, be provided with the second high pressure hand-operated valve 15 at the port of export place of high pressure nitrogen storage tank 12, the pipeline simultaneously between dry powder reservoirs 11 and high pressure nitrogen storage tank 12 is also provided with the second magnetic valve 16 and ring flange 17;
Above-mentioned and lifting motor 2, electric rotating machine 6, infrared thermometer 8, infrared ambulator 9, telescopic spray nozzle 10, first magnetic valve 13, second magnetic valve 16, telescope motor 20 all control by PLC is unified.
The course of work of the indoor dry powder Intelligent fire extinguishing system of the embodiment of the present invention is as follows: when infrared thermometer 8 detects that naked light appears in indoor, signal is sent to PLC, distance between the point of origin that PLC detects according to infrared ambulator 9 and native system executing agency, control lifting motor 2 action, lifting motor drives lifting screw 4 to rotate, crane 5 together declines with the rotating disk 7 of its lower end, electric rotating machine 6 action, rotating disk 7 is allowed to rotate certain angle, ensure that telescopic spray nozzle 10 aims at point of origin, then telescope motor 20 works, under the effect of worm and gear, expansion link 18 is along the axially-movable of self, the jet hose 22 promoting its front end moves towards the direction close to point of origin, first magnetic valve 13 and the second magnetic valve 16 are opened simultaneously, after high pressure nitrogen in high pressure nitrogen storage tank 12 is blown into dry powder reservoirs 11 by pipeline, the dry powder be communicated with in it is ejected into point of origin by pipeline together from jet hose 22, because jet hose 22 has certain pliability, under the effect of gases at high pressure, jet hose 22 under spray regime is all the time in serpentine locomotion, realize fan-shaped, dry powder in certain area sprays, while the effective fire-fighting area of increase, it can also be the environment temperature reduction around point of origin, prevent the intensity of a fire from spreading further, it is excessive that the spring 23 be socketed in outside jet hose 22 then can prevent jet hose 22 to be out of shape, to ensure its spray regime Relatively centralized, simultaneously because the bottom of dry powder reservoirs 11 is set to arc, and the nozzle 25 that the tangential direction along this arc is arranged also is provided with at gases at high pressure entrance 24 place of dry powder reservoirs 11, like this when high pressure nitrogen is blown in dry powder reservoirs 11, can be blown out by the dry powder in it from the bottom to top, the dry powder maximally utilised in it is put out a fire.
If after the dry powder of certain hour sprays, the intensity of a fire still can not get controlling, PLC also can be opened and magnetic valve in the immediate dry powder memory cell in room on fire and between this room executing agency automatically, the dry powder called in this dry powder memory cell is put out a fire, and fundamental system can carry out intelligent fire fighting according to the condition of a fire.
After fire extinguishing, said mechanism is counteragent successively, and the execution part of native system is retracted in ceiling again.
Through after a period of time, when needing to change dry powder, first the first high pressure hand-operated valve 14 at dry powder reservoirs 11 two ends is closed, then the dry powder reservoirs 11 of expired (or sky) is disassembled, reconnect a new dry powder reservoirs 11, and when carrying out the maintenance of high pressure nitrogen storage tank 12 or connecting, need first to close the laggard line operate of the second high pressure hand-operated valve 15.
