Embodiment
As shown in Figure 1 and Figure 2, earthquake Alarm, comprise at least one seismic sensor cable device, and the warning circuit that links to each other with the seismic sensor cable device, it is characterized in that, described seismic sensor cable device comprises shell 1, elastic component 2, ball 3 and telescopic joint, described shell 1 bottom inwall is provided with the base 4 that extends to shell 1 bottom center, telescopic joint is installed on the base 4, ball 3 is positioned at directly over the telescopic joint, and be fixed in elastic component 2 lower ends, and shell 1 inwall top is fixed in the upper end of elastic component 2, and described elastic component is a spring.
By regulating the nut 7 of telescopic joint, can regulate the flexible of telescopic joint arbitrarily, i.e. distance between regulating spring and the ball 3, thus the sensitivity of earthquake Alarm is promptly regulated in the warning when regulating the different earthquake intensity of earthquake.
The structure of the shell 1 similar electron tube of seismic sensor cable device, avoid air turbulence by vacuumizing (vacuum tightness is less demanding) as far as possible, avoid filth and the oxidation of dust and moisture simultaneously, make earthquake Alarm keep higher sensitivity, and prolong life of product greatly hard contact.
Under the normal condition, ball 3 and spring are in relative static conditions, when earthquake takes place when, at first, primary seismic wave (P ripple) is delivered to the seismic sensor cable device, and telescopic joint and shell 1 move upward together, and the spring upper end is fixed with shell 1 and also moved upward simultaneously, because the architectural characteristic of spring has determined that the spring lower end will overcome the elastic deformation that ball 3 brings, therefore will just move upward behind the hysteresis certain hour with ball 3.But before ball 3 moved upward, ball 3 was in relative static conditions, and telescopic joint and shell 1 etc. move upward together, when telescopic joint and ball 3 touch a time-out, connected trigger circuit.When the trigger in the warning circuit detects rising edge, postpone 1-2ms (can eliminate the error of the spacing of ball and telescopic joint like this, also eliminate the discrete discrepancy of spring and electronic devices and components).When 2-3 seismic sensor cable device sensed earthquake simultaneously, when both the trigger of 2-3 connection seismic sensor cable device all has rising signals to transmit, just trigger compressional wave and report to the police, start the shear wave warning circuit simultaneously.Signal by 2-3 seismic sensor cable device compares, and can effectively prevent wrong report.
When the earthquake shear wave was delivered to the seismic sensor cable device, the ball level was waved, when ball 3 contacts with copper ring 9, connect trigger circuit, when trigger detects rising edge, postpone 1-2ms (eliminate the error of ball 3 and copper ring 9 spacings, also eliminate the discrete discrepancy of spring and electronic devices and components simultaneously).When 2-3 seismic sensor cable device sensed earthquake simultaneously, just trigger shear wave and report to the police, eliminate wrong report to greatest extent, close the compressional wave warning circuit simultaneously, avoid repetition of alarms.After postponing 15 minutes, alarm resets, and restarts warning circuit.
Alarm sound can set up on their own in warning circuit, as: earthquake P ripple has come, and primary seismic wave has come! Earthquake S ripple has come, and secondary wave has come! Or the like alarm voice.
Warning light generally adopts the LED light warning of flicker.
In the Wenchuan earthquake aftershock, the utility model detects the 3.7 grades of earthquakes in Wenchuan on May 19th, 2009 in Chengdu, and has sent alerting signal.But 3.7 grades of earthquakes take place in the Wenchuan, and the seismic intensity that passes to Chengdu should be lower than 3 degree, and this shows that sensitivity of the present utility model is too high.Turning down sensitivity, promptly adjusting telescopic joint and change between telescopic joint and the ball after the distance the 3.8 grades of earthquakes in Wenchuan on June 3rd, 2009, not warning when the utility model test in Chengdu.This shows, the utlity model has very high sensitivity, and can realize any adjusting of sensitivity by adjusting telescopic joint.
