Abstract
The utility model relates to a high reliability electronic ignition device, which comprises a normally open switch, a motion mechanism, a shape memory alloy temperature sensing control unit, an electric detonator, a wire and a shell, wherein one end of the normally open switch is connected with the motion mechanism, the other end is fixed on the shell, the shape memory alloy temperature sensing control unit is connected with the motion mechanism and is collocated into actions which control the motion mechanism, which leads the two ends of the normally open switch to separate or close. The two ends of the normally open switch are connected with the electric detonator through the wire, when the two ends of the normally open switch are closed, electric current is transported to the electric detonator through the wire, thereby exciting the electric detonator to work. Because single electric excitation is changed into heat excitation, thereby greatly increasing the high reliability of the electronic ignition device, fundamentally avoiding a false jetting phenomenon, and having the stronger functions of preventing circumscribed power fluctuation and strong electromagnetic interference. The high reliability electronic ignition device has simple structure, can widely use various aerosol automatic sprinklers, is safe and reliable, and has long service life.
Description
Technical field
The utility model relates to a kind of electronic ignition device, particularly a kind of high reliability electronic ignition device that passes through the induced environment temperature triggered that is applied to aerosol fire-extinguishing device.
Background technology
The aerosol fire-extinguishing device is the product of new green environment protection, is zero to the consume latent energy value (ODP) of ozone and chamber effect potential value (GNP), environmentally safe, and the residual life-span is short in atmosphere.Have characteristics such as nontoxic, no burn into is non-hygroscopic, non-conductive, can effectively put out category-A surface-fire, category-B fire and electrical fire.The product applied range; be applicable to the protection in various spaces; particularly suitable is to the protection of precision instrument and equipment, and applicable guard space has: locomotive, steamer, switchgear house, relay bungalow, Generators, cable duct, computer floor, warehouse, storeroom, boiler room, communication base station, automobile engine, engine of boat and ship etc.
The mistake spray problem of aerosol fire-extinguishing device is present the most common situation, and existing many articles that spray case study about mistake are delivered, and concluding is nothing but the controller quality problems.The 24V power supply of control system generally can only 3 (or more) electric detonations of tandem promoter tubing initiator.In order to improve the startup ability, such extinguishing device usually needs to dispose special starter or starts module, and the 24V power inverter is boosted to several hectovolts, excites the electric detonator action through electric capacity charging and instantaneous discharge.
All belong to the Fire extinguisher quality problems and obviously be unfair if will spray the reason of problem by mistake,, the situation to the trust crisis of product own does not take place but because other conventional gas fire extinguishing system is also used the gas fire-fighting controller of same standard.Gas fire-fighting controller is the fire protection sector standard device, and strict anti-electromagnetic interference performance index request is arranged.For a long time, the anti-electromagnetic interference performance index of electric detonator is left in the basket always in the aerosol fire-extinguishing device.In addition, it is problematic that the product standard of electric detonator itself is grafted directly in the fire product standard, because both service conditions differ widely.Electric detonator is to be special application scenario design mostly, be in safe storage state at ordinary times or install after blocking, only (as engineering explosion, explosive welding etc.) just be installed or face facing with front opening locking safeties (as the manual unlocking of capsule ejection, the inertia release of safe automobile air bag etc. of flying) with preceding.And the electric detonator in the aerosol fire-extinguishing device is connected on the complicated control networking, and the loop equivalent area of its absorption of electromagnetic radiation is often very big and can't limit, and is equivalent to be in the ignition state for the treatment of always, thereby the mistake spray takes place easily.
Technically, the problem of aerosol fire-extinguishing product mainly concentrates on the electric detonation tubular type initiator at present.The anti-electromagnetic interference performance that improves electric detonator is priming system industry key subjects always, and the electric detonator technology also is the national defence core technology of the secret not unofficial biography in various countries.As aerosol fire-extinguishing device initiator electric detonator,, seem even more important in the requirement aspect stability and the insensitiveness because of it reaches the online use of several years.Should research and develop special-purpose electric detonator, and increase blocking device, to solve mistake spray problem, life problems and the startup integrity problem of aerosol fire-extinguishing device.
In order to overcome the shortcoming of prior art, need to research and develop a kind of high reliability electronic ignition device that has, it is under the situation of external power-supply fluctuation or under strong electromagnetic interference situation, under strong electromagnetic interference situation such as lightning induction, the induction of charged cloud layer, radio frequency electricity, static, spuious surge current, can not excite electric detonator, the mistake spray does not take place.
