Description
Technical field the invention belongs to the fire-fighting equipment technical field.Be particularly related to a kind of electrical integrated intelligent alarm flame snuffer of full-automatic logic determines controller that integrates ultraviolet, infrared, light sensation.
The conventional fire extinguisher that background technology is used in the market mainly reaches the purpose of fire extinguishing based on fountain by smoke transducer, temperature sensor control water spray, there is following shortcoming in the mode of this fire extinguishing:
1) non-directional fire extinguishing: do not seek the fire point but comprehensive spray, so cause fire, floods to occur simultaneously, floods are also bigger than fire sometimes;
2) fire extinguishing lags behind: in bigger place, space, temperature sensor, smoke transducer are difficult to reach the start-up point, have so just caused the initial stage on fire, reactionless when small size catches fire, and when sensor responded, the intensity of a fire had been difficult to control, causes big loss;
3) cost height: because each spray head range of control is little, the intensive complexity of pipe network made the construction costs costliness when large tracts of land was used; 4) old-fashioned pipe network mostly is a wet type, causes pipe network to freeze easily for cold district, needs to increase the insulation measure, increases the business economic burden.
More existing in recent years enterprises, company have developed some intelligent automatic fire extinguishers, but have gone back defectiveness to a great extent:
1), easily causes wrong report because of the sensor improper use.As: end user's body sensor is as flame sensor usefulness, and this transducer sensitivity is higher, and signal source is all thought in heat radiation, easily hot blast, hot heating installation, powerful illuminating lamp, hot blast pipe network, sunlight reflected or the like all is considered as burning things which may cause a fire disaster;
2) use flame sensor, also exist detection range little, survey angle of visibility little, to the fire that glows problem such as detection effect and cost height not;
3) aspect circuit design, every road sensor needs one to amplify plate, when adopting multiple sensor, need polylith to amplify plate, not only make circuit too complicated, and because motor-field is disturbed, especially stepping motor is when rotating is switched, produce high surge voltage electric current sensing and control circuit are all produced interference, reliability is reduced.
More than the autoscan positioning fire-extinguishing device made of several modes all exist certain location not accurate enough, survey sensitively inadequately, rate of false alarm is than problems such as height.
Summary of the invention purpose of the present invention just provides a kind of accurate positioning, detection is sensitive, rate of false alarm is low, autoscan is located, seek the intelligent alarm flame snuffer that burning things which may cause a fire disaster is followed the tracks of water spray, the fire of nipping in the bud automatically.
Technical solution of the present invention is, a kind of intelligent alarm flame snuffer is made up of probe portion, circuit part and mechanical part, wherein,
A. probe portion constitutes by starting detector, level detector and vertical probe by flame, realizes the accurate detection to characteristic wavelength flame, prevent to disturb and misoperation,
B. in the circuit part, the signal that flame starts detector, level detector and vertical probe enters same amplifying circuit, central processing unit, driving single motor 7 through driving circuit rotates, carry out locating behind level, vertical scanning, the detection burning things which may cause a fire disaster, after central processing unit issues a signal to master-control room, return central processing unit, send warning, open valve and water pump signal
C. in the mechanical part, body 9 is by the fast-assembling dop, vertical hanging is on the fire extinguishing agent pipe network, be connected on transverse axis pipe 4 and the nozzle 1 by vertical shaft feedwater pipe box 8, support 15, substrate 13, motor 7 are fixed on the body 9, the gear 6 of motor 7 is connected successively with gear wheel 14, bevel gear 5, and bevel gear 5 drives transverse axis pipe 4, nozzle 1, realizes single driven by motor level detector seat 3 and 2 rotations of vertical probe seat by gear wheel, carries out level and vertical scanning.
Use shielding line to be connected between sensor and the control circuit and earth point directly is selected on the body, improve the reliability of ground connection, eliminate or the reduction electromagnetic interference (EMI).
The signal that flame starts detector, level detector and vertical probe enters same amplifying circuit, and circuit structure is simplified, and is multiple functional, low in energy consumption, reliable operation, and function admirable, easy to assembly, for integrated, the miniaturization of circuit lays the foundation.
Flame starts detector and is made up of UV sensor, infrared light receiver, optical filter and extinction cover.
Level detector is made up of infra red flame sensor, infrared emanation sensor, UV sensor, concentration piece and extinction cover.
Vertical probe is made up of infrared emanation sensor, infrared light receiver, concentration piece, extinction cover and optical filter.
Optical filter is complementary itself and light source light spectrum, both can see through infrared ray, but the interference of filtering visible light has again improved infrared light transducer[sensor and received and antijamming capability.
Add concentration piece, improve the acceptance rate of infrared sensor, increase receiving range; To flame sensor, thermal radiation sensor, by focusing on the optimum sensitivity of sheet performance sensor.
Made extinction cover and extinction sheet at the signal input port place of sensor, prevented reflection, refraction, the diffraction of signal source, improved accuracy light source.
When being used for flame detecting, respective wavelength is the detector of 4.35 ± 0.15 μ m, and the bandwidth according to flame vibration frequency formulation amplifier improves its reliability and sensitivity.
The invention has the beneficial effects as follows, adopt infra red flame sensor, ultraviolet flame sensor, infrared temperature sensor; Add filtering circuit at detection flame control circuit, strengthen anti-each specific admixture spectrum interference capability; Advanced person's sensing technology is combined with the electronic technology method, add logic control and rational mechanical drive, seal for pipe joints, complex arts such as pressure injection organically combine together, with the automatic fire alarm and the directional fire-extinguishing that take place in the monitored space, fire is eliminated in germinating effectively.
The present invention will be further described below in conjunction with the drawings and specific embodiments for description of drawings.
Fig. 1 is a schematic appearance of the present invention.
Fig. 2 is a structural representation of the present invention.
