Abstract
The utility model discloses an earthquake alarm meter comprising an earthquake detection and sensing device, a trigger circuit, an alarm system and a power supply system, when the earthquake detection and sensing device detects the activities of the earthquake, trigger signals are generated so as to activate the trigger circuit, the trigger circuit starts working in the arrival of the trigger signals to start the alarm system and push the loudspeaker to work, thereby realizing automatic alarm function. The utility model is characterized in that: the existing earthquake detection and sensing equipment is added with automatic trigger alarming function, so that people can be prompted to avoid hazard and expand succor at the first time of the earthquake arrival, moreover the utility model provides an earthquake detection and sensing device composed of an earthquake movement sensing ball and an earthquake movement sensing head. The utility model has the advantages of simple structure, reliable operation and low cost, and is suitable to be popularized.
Description
Technical field
The utility model relates to a kind of seismic survey induction installation, relates to a kind of energy-conservation trigger circuit with secondary delay function again.
Background technology
Existing seismic sensor cable equipment is a lot, and is also very advanced, but be only limited to national scientific research department and relevant unit's use, do not have popularization and generalization, concerning the vast masses, do not have applicability.
The utility model can use the circuit with secondary delay function to make trigger circuit, and its patent No. is ZL 200520061999.7.Not power consumption under this circuit static state supporting down that dynamically secondary triggers, and the time-delay certain hour can be closed automatically after finishing last triggering, enters static state.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes prior art, provide a kind of higher to the seismic activity reaction sensitivity, can also send simultaneously the earthquake alarm of alerting signal automatically, the very first time reports to the police automatically in the time of can taking place in the little shake before earthquake is arrived or shaken greatly, reminds timely hedging of the masses and rescue.
Another purpose of the present utility model provides a kind of simple in structure, reliable, and cost is lower, is easy to the seismic sensor cable device of penetration and promotion.
More than first purpose adopt following technical scheme just can realize:
Scheme comprises seismic survey induction installation A, trigger circuit B, warning system C and electric power system D.
When seismic survey induction installation A detects seismic activity, produce trigger pip, remove to trigger trigger circuit B, trigger circuit are started working when trigger pip arrives, and start warning system C, promote speaker operation.
More than second purpose adopt following technical scheme to realize:
The centre of this scenario-frame is a seismic activity induction sphere 3-1, the induction sphere bottom contacts with a middle part base plate 3-2 low, that high, the gradient is suitable on every side, reaching the top all around then directly contacts with seismic activity inductive head 3-3 or keeps certain distance, each inductive head is separately fixed on the corresponding circuit board 3-4, the circuit board that is used for fixing inductive head around the induction sphere all is fixed on anchor post or the fixed head 3-5, forms a whole (see figure 3).
The utility model has the advantages that:
1. for first kind of technical scheme, owing to add automatic triggering warning function on existing seismic survey sensing apparatus, the timely hedging of very first time reminds people that can arrive in earthquake and carry out rescue reduces injures and deaths as far as possible.Like this, advanced scientific payoffs just can apply to human real life better, for the mankind benefit.
2. for second kind of technical scheme, simple in structure owing to what adopted, and higher sensitivity is arranged, thereby reliable, cost is not high, is fit to popularize and promote.
The utility model is more clear to be understood with being convenient in order to make, and below by drawings and Examples it is described in further detail.
Description of drawings
Fig. 1 is the principle of work block scheme of a kind of embodiment of the utility model.A is the seismic survey induction installation among the figure, and B is trigger circuit, and C is a warning system, and D is an electric power system.
Fig. 2 is the embodiment of electric power system D in the principle of work block scheme.F is a civil power among the figure, and G is a charging circuit, and H is an accumulator.
Fig. 3 is the front view after the parts of a kind of embodiment of the utility model assemble.3-1 is the seismic activity induction sphere among the figure, and 3-2 is a base plate, and 3-3 is the seismic activity inductive head, and 3-4 is a circuit board, and 3-5 is anchor post or fixed head.
Embodiment
Embodiment 1, sees Fig. 1.When seismic survey induction installation A detects seismic activity among the figure, produce trigger pip, remove to trigger trigger circuit B, trigger circuit are started working when trigger pip arrives, and start warning system C, promote speaker operation, thereby realize automatic warning function.
Embodiment 2, see Fig. 2.Present embodiment is on the basis of embodiment 1, a kind of embodiment that described electric power system D can adopt.Civil power F gives charging circuit G power supply, and charging circuit inserts the power supply of civil power accumulators, and accumulator is the final power supply output stage of electric power system D (referring to Fig. 1).When accumulator electric-quantity was not enough, charging circuit automatically switched to charged state, is charge in batteries; When accumulator electric-quantity was sufficient, charging circuit automatically switched to non-charged state; Between the civil power turnoff time, not power consumption of charging circuit.Select for use the advantage of this embodiment to be, the influence that the detection alarm function is not had or not by the short time civil power.
Embodiment 3, see Fig. 3.Present embodiment is on the basis of embodiment 1, the embodiment that described seismic survey induction installation A can adopt.The centre of this scenario-frame is a seismic activity induction sphere 3-1, the induction sphere bottom contacts with a middle part base plate 3-2 low, that high, the gradient is suitable on every side, reaching the top all around then directly contacts with seismic activity inductive head 3-3 or keeps certain distance, each inductive head is separately fixed on the corresponding circuit board 3-4, the circuit board that is used for fixing inductive head around the induction sphere all is fixed on anchor post or the fixed head 3-5, forms an integral body.
Claims (3)
1, a kind of earthquake alarm, comprise seismic survey induction installation A, trigger circuit B, warning system C and electric power system D, it is characterized in that: when seismic survey induction installation A detects seismic activity, produce trigger pip, remove to trigger trigger circuit B, trigger circuit are started working when trigger pip arrives, and start warning system C, promote speaker operation.
