Abstract
The invention relates to an automatic temperature-sensing piezoelectricity generator which is characterized by comprising a temperature-sensing glass ball and a piezoelectric crystal, wherein the impact hammer in the tube cavity of the shell is opposite to the piezoelectric crystal; the piezoelectric crystal in insulating cement is provided with a negative wire and a high-voltage positive wire which pass through the shell and are linked with an ignition head without a bridge wire; the rear end of the impact hammer is compressed in the tube cavity through a spring and a nut; the middle part of the shell is communicated with a hollow bracket; the upper end of the temperature-sensing glass ball of the tube body in the hollow bracket center abuts against the right center at the bottom edge of a triangular impact hammer fixture block; the obtuse angle end of the impact hammer fixture block locks the edge of the impact hammer; and the top wire abuts against the other end of the temperature-sensing glass ball tube body. When the environment temperature reaches or exceeds the blasting temperature of the temperature-sensing glass ball, the temperature-sensing glass ball blasts; the impact hammer fixture block falls off; a compression spring pushes the impact hammer to rapidly impact the piezoelectric crystal; the 6,000-30,000 volt voltage is instantly generated; and the ignition head without the bridge wire which is linked with the high-voltage positive and negative wires is ignited, thus a power supply does not need to automatically ignite an aerosol generating agent or ignite an explosive material to start an extinguishing agent release valve and start an extinguishing device.
Description
Technical field
The present invention relates to automatic fire extinguisher, the automatic piezo-electric generator of a kind of temperature-sensitive.
Technical background
The miniature igniter of electrically-ignited piezoelectric ceramic type fireworks and firecrackers of the prior art, Chinese patent Granted publication CN200720117021.7, this utility model comprises igniter head of cavity, top cover, bottom, band point heated filament, be arranged on the security insurance spring, piezoelectric ceramics and the positive and negative electrode lead that are arranged on the button below in button on the top cover, the cavity, piezoelectric ceramics top connects button by the security insurance spring, and piezoelectric ceramics connects positive and negative electrode lead tie point duration and degree of heating respectively.This design utilizes piezoelectric ceramics to produce instantaneous pressure by pressure and lights fireworks and firecrackers.
The advantage of the miniature igniter of this electrically-ignited piezoelectric ceramic type fireworks and firecrackers is: must start manually, need not to get angry, have higher security.
See the starter of a kind of aerosol fire-extinguishing device of the prior art again, Chinese patent Granted publication CN201558439U sees Fig. 1, it is characterized in that described voltage starting power supply 1 is made up of starting switch 2, impact block 3 and piezo-electric crystal 4; The input of piezo-electric crystal 4, output join with the lead that the parallel root that is provided with of the bar in twos of igniter head 5 does not have overlap joint respectively; Starting switch 2 is vertically mounted on the top of starter; Impact block 3 is fixedlyed connected with starting switch 2; Has the gap between impact block 3 and the piezo-electric crystal 4.When starting power supply 1 by lower piezoelectric, the no bridge silk igniter head 2 that ignites, igniter head 2 aerogel generating agent that ignites starts aerosol fire-extinguishing device and puts out a fire.
The shortcoming of the starter of this aerosol fire-extinguishing device is: when breaking out of fire, must start aerosol fire-extinguishing device manually, so the essential Attended mode of aerosol fire-extinguishing device can not be used in unattended position.
Using piezoelectric ceramics ignition and blasting technology in fact, had been widely-used before foregoing invention.During World War II, the ammunition expert uses piezo-electric effect to detonate the device, and loads onto the crystal of piezoelectric ceramics class at the front end of bomb, and when the bomb front end is under pressure when impacting, piezoelectric ceramics moment produces high voltage electricity, detonates the device.After the World War II, Japanese's success piezoelectric ceramics is used on the lighter.
Summary of the invention
The purpose of this invention is to provide the automatic piezo-electric generator of a kind of temperature-sensitive, can need not the power supply automatic constant temperature aerogel generating agent that ignites, start the aerosol fire-extinguishing device fire extinguishing; Or the explosive that ignites starts the extinguishing chemical relief valve, the fire extinguishing of startup extinguishing device.
The automatic piezo-electric generator of a kind of temperature-sensitive, comprise column temperature-sensitive glass marble, piezo-electric crystal, it is characterized in that in the piezo-electric generator housing tube chamber: impact hammer is with to be positioned at housing cecum piezo-electric crystal relative, being worth in the piezo-electric crystal of insulation in the fixing glue has high-voltage positive electrode lead, the cathode conductor that passes the no bridge silk igniter head of housing link, and impact hammer rear end contact spring also is compressed in the tube chamber by nut; Communicate with piezo-electric generator housing hollow out support in the middle of the piezo-electric generator housing, the hollow out support center of circle holds column temperature-sensitive glass marble, the edge that impact hammer is withstood in column temperature-sensitive glass marble upper end blocks impact hammer, withstands column temperature-sensitive glass marble in the hollow out bracket end by jackscrew.Come off after the explosion of column temperature-sensitive glass marble temperature-sensitive, the impact hammer of pinning rapid percussive pressure electric crystal under the promotion of compression spring makes piezo-electric crystal moment produce high-tension electricity, no bridge silk igniter head that high tension electric ignition and positive wire, negative conductor link.
When work, when environment temperature meets or exceeds column temperature-sensitive glass marble explosion temperature, the explosion of column temperature-sensitive glass marble, come off after blocking the column temperature-sensitive glass marble explosion of impact hammer, the compression spring promotes the rapid percussive pressure electric crystal of impact hammer, make 6000～30000 volts of high-tension electricities of piezo-electric crystal moment generation, light, start the aerosol fire-extinguishing device fire extinguishing by no bridge silk igniter head of piezo-electric crystal high pressure both positive and negative polarity wire link.This is to use extinguishing chemical relief valve opening ways very widely.
The present invention has heat detection and starts the incorporate advantage of extinguishing device.Outstanding advantage is to need not the automatic temperature-sensitive of the power supply aerogel generating agent that ignites, and starts the aerosol fire-extinguishing device fire extinguishing.According to environment for use fire prevention temperature requirement, the different explosion temperature of column temperature-sensitive glass marble are set, can make like this that this product range of application is wider, safety, safety factor is higher.
