Embodiment
As shown in accompanying drawing 1, Fig. 2 and Fig. 3, a kind of earthquake prediction apparatus, comprises ground warning system, surface seismic prognoses system and subsurface seismic prognoses system.
Ground warning system is made up of power supply 1, base 3, balancing spring 12, relay 4, cross bar 11, contactor 10, loudspeaker 9 and iron plate 18.
Relay 4 and balancing spring 12 are installed on the base 3, are provided with cross bar 11 above it, and iron plate 18 is arranged on the below that cross bar 11 has relay 4, and contactor 10 is arranged on above cross bar 11 other end.
Surface seismic prognoses system is by pendulum 5a, 5b, U-shaped connector 6a, 6b, cross bar 7a, 7b and bulb 8a, and 8b, 8c, 8d form.
U-shaped connector 6a, is provided with cross bar 7a, 7b above 6b, pendulum 5a, 5b hanging wire is by U-shaped connector 6a, 6b bottom centre.
Subsurface seismic prognoses system is made up of shell 15, base 13, spring 14, iron ball 17, coil 16 and iron ring 19.
Base 13 is provided with spring 14, spring 14 top is provided with cross, cross is provided with iron ball 17, and shell 13 position concordant with iron ball 17 is provided with coil 16, is provided with iron ring 19 inside coil 16.
Power supply 1 positive pole is connected with iron ring 19 with contactor 10, U-shaped connector 6a, 6b by switch 2b, power supply 1 negative pole and relay 4, loudspeaker 9 and bulb 8a, and 8b, 8c, 8d connect.
Power supply 1 is connected with coil 16 by switch 2a.
Bulb 8a, another pole of 8b, 8c, 8d and cross bar 7a, 7b connect, and cross bar 7a, 7b are connected with another pole of relay 4, and spring 14 is connected on contactor 10.
Ground warning system and surface seismic prognoses system are by a, b, c, d and a ', b ', c ', d ' tie point connects.
The principle of work of this earthquake prediction apparatus is as follows: when the earthquake initial stage, because vibrations make pendulum 5a, 5b shakes, and U-shaped connector 6a, 6b touch cross bar 7a, any one section of 7b, thus make bulb 8a, 8b, 8c, 8d are connected with power supply 1, bulb 8a, one or more in 8b, 8c, 8d light.Meanwhile, when U-shaped connector 6a, 6b touch cross bar 7a, any one section of 7b, relay 4 is connected with power supply 1, produces magnetic field, by cross bar 11 right-hand member toward drop-down, make cross bar 11 that iron plate 18 is connected 10 with contactor, thus loudspeaker 9 is connected with power supply 1 sound the alarm.Cut off the electricity supply with switch 2b, relay 4 loses magnetic field, and cross bar 11 is returned to original position by balancing spring 12.
By switch 2a, coil 16 is connected with power supply 1, coil 16 produces magnetic field.Because magnetic field strength in individual direction all with, the iron ball 17 on the cross of spring 14 top is still in coil 16 center.When earthquake generation generation is rocked, spring 14 is also along with rocking, and iron ball 17 is adsorbed by iron ring 19, thus relay 4 is energized, and by cross bar 12 toward drop-down, makes cross bar 11 that iron plate 18 is connected 10 with contactor, thus loudspeaker 9 is connected with power supply 1 sound the alarm.
The degree of depth its sensitivity darker that subsurface seismic prognoses system is embedded in underground is higher.
Two pendulums of surface seismic prognoses system are placed in north and south and east-west direction, thus can detect the earthquake wave of different directions.
After earthquake, or because of after other reasons warning, system can by cutting off and close a switch 2a and 2b recovery.
Power supply 1 can use 12 ~ 24V direct supply.
