Description of drawings
Fig. 1 is the electrical schematic diagram of the utility model embodiment;
Fig. 2 is the structural representation of the utility model embodiment.
Embodiment
Below by embodiment and accompanying drawing thereof the utility model is described in further detail:
Referring to Fig. 1, Fig. 2, this acousto-optic earthquake alarming device comprises rectangular housing 1, controller.The loudspeaker Y, direct supply G, illuminating lamp LED, power switch K, the search switch that circuit board A are arranged in the controller and be electrically connected with it.Circuit board A, loudspeaker Y, direct supply G are located in the housing 1, illuminating lamp LED is located on the upside side plate of housing 1, also have some sound transmission aperture 11 on the upside side plate of housing 1, power switch K is located on the left side side plate of housing 1, and search switch control circuit board A is to realize sound and light alarm.Search switch is located in the housing 1 and comprises glass mercury conductive switch JK, a piezoelectric ceramic piece B, piezoelectric ceramic piece B is formed by stacking successively by silver layer, ceramic layer, copper sheet layer from top to down, piezoelectric ceramic piece B is bonded on the base plate in the housing 1 by the copper sheet layer, vertically be connected to feeler 2 on the downside of copper sheet layer, housing 1 (promptly stretching out base plate) is stretched out in the lower end of feeler 2, and the silver layer of piezoelectric ceramic piece B, copper sheet layer are connected with the control utmost point of controllable silicon VS, the negative electricity of direct supply G respectively.
For the purpose of saying something, housing 1, illuminating lamp LED, circuit board A, power switch K, piezoelectric ceramic piece B, feeler 2 only schematically draw among Fig. 2 brief and concisely.
When mercury cut-off JK is installed, make the mercury end down, two wires make progress, and at ordinary times, two wires are in nonconducting state; During the work of this acousto-optic earthquake alarming device, housing 1 is put on the ground, made the reliable kiss the earth in lower end of feeler 2.
After the power turn-on K switch, the principle of work of this acousto-optic earthquake alarming device is:
At ordinary times, controllable silicon VS is in cut-off state, and entire circuit is in monitoring and treats alarm condition (being state on duty, this not power consumption of state).When seismic activity, utilize feeler 2 can collect earthquake delicately and pass to ground earthquake sounds from crust depth at the beginning of taking place, piezoelectric ceramic piece B is shaken and is produced piezoelectric effect, produce the alternation induced voltage at its two ends, controllable silicon VS obtains the forward trigger current and conducting (in other words, direct supply G makes controllable silicon VS triggering and conducting through piezoelectric ceramic piece B) by piezoelectric ceramic piece B; And then, utilize glass mercury conductive switch JK can collect the seismic event (compressional wave that destructive power is little) that passes to ground bob after the earthquake from crust depth delicately, switch JK is jolted and closure, controllable silicon VS also can pass through resistance R 1, switch JK obtains the forward trigger current and conducting (in other words, direct supply G makes controllable silicon VS triggering and conducting through resistance R 1, switch JK).
After the controllable silicon VS conducting, make circuit board A electricly and work rapid.Aural signal promotes the loudspeaker Y sounding after transistor VT amplifies on the one hand, wakes owner up and notes, illuminating lamp LED lights on the other hand, can improve indoor environment brightness, is convenient for people to when night earthquake taking place, and meets an urgent need and hides.
Therefore, any one search switch (being connected to the piezoelectric ceramic piece B or the glass mercury conductive switch JK of feeler 2) all can be realized sound and light alarm, possesses the function of dual fail-safe, so that the performance quite stable of this acousto-optic earthquake alarming device.Like this, people can strive for escaping rapidly in tens seconds before the huge shear wave of destructive power arrives, and injures and deaths are reduced to minimum degree.
In case the generation sound and light alarm will continue endlessly, up to disconnecting power switch K, cut off the electric current of controllable silicon VS, alerting signal stops just now.In addition, this acousto-optic earthquake alarming device also can be placed in door and window etc. and locates, and brings into play antitheft effect.
The voltage of direct supply G is 6V, with obtaining after the 4 joint dry cell series connection; Power switch K is long closed form pushbutton switch; Piezoelectric ceramic piece B selects FT-27 or HTD27A-1 type for use; Glass mercury conductive switch JK selects the KG-205 type for use; Resistance R 1, R2 select RTX-1/8W type carbon film resistor for use; Controllable silicon VS selects plastic packaging one-way SCRs such as MCR100-6 or 2N6565 for use, requires control utmost point trigger current Ig≤30 μ A; Capacitor C is selected CD11-10V type electrolytic condenser for use; Illuminating lamp LED selects the high brightness white light-emitting diode for use; Circuit board A selects the KD9561 integrated package for use, and it can send the sound of police car, fire truck, ambulance and machine gun; Loudspeaker Y is selected 8 Ω small-sized electric loudspeaker for use; Transistor VT selects 9014 or 8050 type silicon NPN low-power transistors for use, requires currentamplificationfactor〉150.
Certainly, circuit board also can be selected the audio manifold block of other model for use, and piezoelectric ceramic piece also can adopt ZO
2Type high sensitivity sheet vibration module, the shape of shell also can be done circular or other suitable shapes, and such conversion all drops within the protection domain of the present utility model.
