The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, this single-motor switched scan-type fire extinguisher is arranged at indoor top, is connected through sealing ring (2) and the snap joint on the pipeline by fast interface (1).Water pump control end and alarm, display and relative connection of the rearmounted IC2 output of Fig. 5 computer, stator (4), chassis (5), stepper motor (27), circuit board and dried spring device (22) are all fixing with stator (4), the motor gear (21) of its stepper motor (27) downwards and the 180 ° of free gears (7) on the main shaft (3) be meshing with each other, 180 ° of free gears (7) are fixed as one with the bevel gear (20) of bottom, with transverse axis (18) on bevel gear (30) engagement after, they form a complete transmission mechanism nozzle body (9) pitching scanner (32) and two water spouts (31), use when the function of this sets of transmission mechanism is backstroke scanning point of origin (26), what its another set of stepper motor (27) was used when just changeing is the function of using when scanning point of origin (26) as horizontal scanner (16).Its transmission mechanism is dialled terminal (23), flange (8), cavity (19) and horizontal scanner (16) by 180 ° of free gears (7) and is formed.
Dynamically the function of fire extinguishing as shown in Figure 1, this moment, fire extinguisher was static standby, water spout (31) is downward, hydrodynamic(al) valve (12) is shut by block (13) two water spouts (31) stuck, infrared receiving tube starter (14), the signal of telecommunication of horizontal scanner (16), the signal of telecommunication of pitching scanner (32) all is to derive by dialling terminal (23) through lead, on (3) 180 ° of circuit boards (28) that feed on the chassis (5) of main shaft, it is logical that above-mentioned enabling signal P1 and Fig. 5 P1 start the amplification termination, the A0-A3 output control of computer, stepper motor (27) begins to rotate counterclockwise, the free empty road of semicircle on 180 ° of free gears (7) (24) one ends block dials terminal (23) promotion main shaft (3), cavity (19), its nozzle body of horizontal scanner (16) (9), transverse axis (18) begins horizontal sweep together, when the scanning cylindrical void (15) of horizontal sweep (16) and inside center infrared receiving tube and point of origin are sight alignment, point of origin (26), the photoelectric tube photosignal amplifies end through the P2 level that P2 output enters IC1, the counter-rotating clockwise of the A0-A3 output signal control step motor (27) of computer IC1 beginning at this moment.Again referring to Fig. 3, stepper motor (27) counter-rotating drives 180 ° of free gears (7) to be changeed counterclockwise, by dial terminal (23) 180 ° of free gears (7) in the free empty road of semicircle (24) can not block dial terminal (23) and this moment main shaft (3) and water spout body (9) to aim at point of origin (26) directed motionless, otherwise the counter-rotating of the transmission mechanism of stepper motor (27) and water spout body (9) is rotated.Again referring to Fig. 4; the transmission mechanism of stepper motor (27) drives bevel gear (30) and transverse axis (18) through bevel gear (20); water spout (31); pitching scanner (32) is looked up scanning from bottom to top; when the infrared sensor in the pitching scanner (32) receives point of origin (26) signal of telecommunication; just there is the signal of telecommunication to amplify end by the P3 pitching that P3 is input to computer IC1; at this moment stepper motor (27) stall; each output signal of the P6-P9 of computer IC1 is controlled motor-driven valve simultaneously; electrodynamic pump; display screen; alarm starts simultaneously; the electrodynamic pump supply fire extinguisher that rapidly water boosted; by the water channel (6) of fire extinguisher via main shaft (3) to transverse axis (18); after transverse axis hole (10) enter water cavity (11) again and all press; spray to point of origin (26) from the jet face of two water spouts (31) ejection and formation high pressure; at this moment hydrodynamic(al) valve (12) is sprayed by hydraulic pressure; drawing lines (29) satisfies pitching scanner (32); the motion chamber of cavity (19); its injecting time of once putting out a fire is 30 seconds; after 30 seconds; stepper motor (27) begins to rotate counterclockwise; continue to promote to dial terminal (23) and main shaft (3); horizontal scanner (16) scanning is until 360 ° of one weeks of terminal point; the position that dried spring device (22) is provided with; the permanent magnet of dialling terminal (23) upper top is with dried spring device (22) magnetization action adhesive conducting; the computer IC1 input that commutates; stepper motor this moment (27) beginning counter-rotating clockwise; at this moment it is motionless in the free empty road of semicircle (24) of 180 ° of free gears (7) to dial terminal (23); when turning over 180 °; the semicircle of 180 ° of free gears (7) is freely controlled (24) and is over; begin card pushing terminal (23) and main shaft (3) again and drive 360 ° of whole mechanism revolutions; at this moment dialling the P4 commutation end control step motor that signal that permanent magnet on the terminal (23) triggered dried spring device (22) output that is located on the chassis (5) again is input to computer IC1 shuts down behind 200 ° of angles of counter-rotating counterclockwise; it is used that transverse axis cap (25) is that two ends water body (9) is regulated O type water seal (17) mutually; its above-mentioned scanning process is the fire extinguishing procedure of a random process of this single-motor switched scan-type fire extinguisher; once return reset condition after the fire extinguishing, be in holding state again.There is fire to start for the anti-interference of infrared receiving tube and judgement, be to judge and calculate its frequency by computer program, identification is handled light and is distinguished with fire, therefore have strong interference immunity, simple in structure, cost is low, the life-span is long, reached can intelligent decision and discern burning things which may cause a fire disaster, reaction speed is fast, the effect that the fire extinguishing rate is high.
