Abstract
The utility model discloses a sound seismic alarm, which is composed of a tailor-made probe head K which measures an earthquake, an electronic delay circuit, a switching tube, an audio frequency oscillator, and a buzzer. When microseism occurs, the probe head K which measures the earthquake switches on, the circuit works, the buzzer sends out alarm sound to alarm draw near the earthquake rapidly and effectively. The utility model has the advantages of simple device, high reliability, low cost, and applicability. The alarm is suitable for families and units.
Description
The utility model relates to earthquake Alarm, relates in particular to a kind of family, unit use imminent earthquake sound equipment earthquake Alarm.
Existing seismic instrument, metering device mainly are to be used for measuring observation earthquake number of times, intensity and distribution abnormal conditions, Chinese patent CN87105023 announces a kind of sensitive earthquake alarm, it mainly is by active support by the weight ball, drive semi-circular lever transmission pointer by the ball axostylus axostyle, can measure seismic direction, the angle of inclination, the earthquake centre point, and can report to the police.But this warning device, inconvenience is carried, and the manufacturing process complexity costs an arm and a leg, and is difficult to enter family, unit.
The purpose of this utility model provides a kind of imminent earthquake sound equipment earthquake Alarm that is suitable for family, unit use.It is simple in structure, reliable, suitable, and is cheap, need not keep an eye at ordinary times, does not need the full-time staff to operate.
The purpose of this utility model can reach by following measure: a kind of sound equipment earthquake Alarm, comprise electronic delay circuit, switching tube, audio frequency oscillator, news Chinese percussion instrument, it is characterized in that designing the probe K of a special measurement earthquake, it is made up of contact 1, touch base 2, messenger wire 4, lead 5, fixed mount 6, and its function plays on-off action.
The utility model can also reach by following measure: contact 1 and touch base 2 adopt metal to make.Messenger wire 4 adopts nylon wire; Also can adopt other high strength union twist yarn.Lead 5 is around messenger wire 4 upper tops to the machine box 3; Consider also can adopt multi cord from intensity.
The utility model has following advantage than prior art: be suitable for family, unit use, and simple in structure, suitable, reliable; Cheap.
