Water bottle (seeing Fig. 2 water bottle synoptic diagram) top is that the garden is tapered, surface level is in tapered face portion on the lower side, photoelectric tube is below surface level, and the light when LED photoelectric tube (14. photoemission cell) sends shines the water surface, according to the reflection of light principle, incident angle=emergence angle, 16. photoelectric receiving tubes receive emergent light, as long as slight vibrations are arranged, the water surface just has the ripples fluctuation, emergent light just changes, and the electric current of 16. photoelectric receiving tubes will diminish, and voltage raises, 17. electric capacity charging, 18. triode b pole tension raises, electric current increases, and constitutes signal inversion, be the ripples fluctuations, 16. the photoelectric receiving tube electric current diminishes, phase inverter voltage raises, and 18. triode b pole tensions raise, the triode conducting, the water level fluctuation signal that just responds out output.20. triode b electrode current increases, the triode conducting, and the 20. triode b utmost points extremely link to each other with 18. triode c, and the water level fluctuation signal amplifies output.Played the effect that the vibration signal collection is oppositely amplified.
The principle (see figure 1) of DC power voltage stabilizing circuit:
The family expenses alternating current is through 6～9 volts direct currents of transformation rectification output, through 1. sockets, through 2. electric capacity, 3. electric capacity, 4. stabilivolt, 5. electric capacity, 6. electric capacity is stabilized in 5 volts with voltage, output to 10. switches and power.11. resistance and 12. pilot lamp (light emitting diode) link, whether the pilot lamp indicating circuit has.
The beneficial effects of the utility model are:
Can monitoring also can report to the police from the slight vibrations of any direction of three dimensions.Simple in structure, cost is low.Can be used for household earthquake monitoring or vibration monitoring.
Illustrate:
The distant relative must be upwards static with the placement of earthquake ripples alarm, can not rotate, and is placed on the place that can react vibrations.
