Abstract
The utility model relates to an indoor earthquake voice alarm machine, which is mainly suitable for an indoor earthquake forecasting alarm device with sound prompting. The indoor earthquake voice alarm machine is mainly composed of a sensing part, a control part, and an alarm part. A key seismic longitudinal wave sensor is mainly composed of Hall elements. The utility model has the advantages of timely, correct, and rapid alarm, simple structure, small size, light weight, and convenient installation and operation, which is suitable for households and other rooms.
Description
The utility model mainly is applicable to the indoor warning machine that has voice suggestion that predicts an earthquake.
Earthquake is a kind of irresistible disaster, and predicting an earthquake effectively is in the world a great problem.Common earthquake, will produce two kinds of ripples, it passes first compressional wave toward ground from the earthquake centre with the fastest speed, and accompany by the overcast rumbling sound, be difficult in time being realized, especially when earthquake occurs in that night, people slept soundly by people, or relatively more noisy indoor place, more can't discover coming of disaster, this compressional wave also can be described as pre-seismic wave, and its destruction is little.It two is shearing waves of earthquake, it than compressional wave slow about 30 seconds, it breaks with tremendous force, impact failure power is big.Present various prediction and alarm devices, as " earthquake siren for household " (patent No. is 94240014.3) and " earthquake early warning clock " (patent No. 89210162.8) or the like, wherein weak point is an inductor manufacture technology requirement height, sluggish to the compressional wave induction, there is not voice prompt alarm in addition, have only sound and light alarm, easily make people in high-pressure and fear, be at a loss.Also have to cut into a mountain, seismic survey, rainmaking and other accidental explosion accident easily report by mistake, consequence is serious ....
The utility model mainly is to utilize primary seismic wave to be sensed as the master just can report to the police, and a kind of warning device of voice suggestion is arranged again.
The utility model is to realize like this, this machine mainly partly is made up of sensing, control and warning, utilize the compressional wave (its leading shearing wave is about 30 seconds) of earthquake just can report to the police, (be exactly the circuit that utilizes Hall element to form mainly by primary wave sensor, flashing and the earthquake voice prompt alarm, more particularly, is exactly when earthquake takes place, at first by the Sensor section turn-on control circuit, this control circuit conducting sound circuit immediately sends voice and luminous warning.And transducing part is mainly by ining succession small magnet under the spring, and corresponding primary wave sensor, and the compressional wave sensor mainly is made up of Hall element, its connection controllable silicon and audio alert and luminous warning part.
The utility model can be realized the forecast of certain earthquake magnitude by the size of selecting to hang the small magnet spring, report to the police in time, correctly rapid, simple in structure, volume is little, in light weight, easy for installation, the place that can be placed in indoor wall, window wall separately or be difficult for being bumped by the people, also can constitute it and crystal clock, perhaps be combined into indoor earthquake alarm system with pendent lamp or wall lamp, this all is convenient to indoor popularization.
Further specify below in conjunction with accompanying drawing: Fig. 1 is a chamber earthquake audio alert machine circuit principle of work synoptic diagram, and Fig. 2 is the schematic appearance of chamber with earthquake audio alert machine.
Fig. 1 primary wave sensor (HC), the pin 2 output noble potentials of sensor (HC) are connected integrated of voice (SR) for the conducting of controllable silicon (SCR) control panel, drive loudspeaker (Y) and send audio alert, while is conducting light emitting diode (D) also, makes it to send luminous warning.Integrated (SR) positive pole of voice connects sensor (HC) pin 1 by switch (K), and negative pole connects (HC) pin 3, and both positive and negative polarity is also corresponding to voice sheet (SR), and resistance R 1 and R2 are respectively the current-limiting resistance of sensor (HC) and light emitting diode (D).Spring-hanging board (6) is connecting spring (7) and small magnet (B), small magnet (B) and sensor (HC) partition distance (H).
Fig. 2 is after this cover warning machine is installed, and user mode of living in can be seen from perspective window (8), is suspended in the induction small magnet (9) that plays below the spring (7) on the spring-hanging board (6).When earthquake takes place, at first in time sense the impact of the primary seismic wave that people are difficult for feeling by the small magnet (9) of transducing part, when impulsive force surpasses the certain earthquake magnitude value set, the small magnet that is draped (9) is by hanging Hall element (HC) sensitizing range of extension spring (7) in correspondence, do upper and lower motion, make Hall element (HC) induce certain pulse electrical signal, trigger controllable silicons (SCR) by 2 pin output and led to circuit and power up, make sound circuit (SR) drive loudspeaker (Y) 4 and send brief (earthquake! An earthquake! Not frightened busy, hasten to seek point of safes! Deng) warning of flashing of voice suggestion and illuminating circuit.Switch (3) is a total power switch, battery (11) power supply.
Claims (2)
1, chamber earthquake audio alert machine, it partly is made up of sensing, control and warning, it is characterized in that transducing part is mainly by the small magnet of ining succession under the spring, and corresponding primary wave sensor, the compressional wave sensor mainly is made up of Hall element, but and is connecting silicon and audio alert and luminous warning part.
2, by the described chamber of claim 1 earthquake audio alert machine, integrated (SR) positive pole of voice that it is characterized in that the audio alert part connects sensor (HC) pin 1 by switch (K), negative pole connects sensor (HC) pin 3, both positive and negative polarity is corresponding to voice sheet (SR), resistance R 1 and R2 are respectively the current-limiting resistance of sensor (HC) and light emitting diode (D), spring-hanging board (6) is connecting spring (7) and small magnet (B), small magnet (B) and sensor (HC) partition distance (H).
