Abstract

The invention discloses an earthquake alarm with ringtone and voice double functions. When an earthquake happens, a house shakes and drives the earthquake alarm which is connected with a ceiling by a rigid rod to shake while a suspension plummet which is hung on the ceiling in a suspension way by a flexible rope oscillates; and due to the different amplitudes of oscillation of the earthquake alarm and the suspension plummet, the suspension plummet hung by the flexible rope in a suspension way and a convex spherical face in the alarm move relatively, the suspension plummet drives a steel ball to roll down from the top of a guide rail of the convex spherical face into an circular groove of a connection plate first, a ringtone alarm circuit is turned on, a direct current motor is started to drive a reducer to rotate and a ratchet on an output shaft to rotate, so that an oscillating pawl and a plummet are driven to oscillate to strike a bell to give an mechanical alarm. When the steel ball rolls down from the top of the guide rail of the convex spherical surface, an approach switch is closed, a voice alarm circuit is turned on and a voice module works, so that a loudspeaker gives a voice alarm.

Description

The difunctional earthquake alarming device of the tinkle of bells and voice

Technical field: the present invention relates to a kind of earthquake alarming device of electromechanical integration technology, can in time send a kind of earthquake alarming device that existing the tinkle of bells has voice again when earthquake specifically takes place.

Background technology: earthquake is the great disaster of a kind of harmfulness, and casualties that ruinous earthquake causes and property loss are huge, if earthquake occurs in the late into the night, in people slept soundly, that consequence was hardly imaginable especially.If can before violent earthquake is attacked or before the earthquake generation destructive lesion, in time report to the police, even only be several seconds, people are prepared in advance or timely hedging, reduce personal injury and property loss greatly.

Abroad, Japan develops " urgent rapid earthquake information report " system, but this system price is very expensive, and every about 200,000, also need to set up special observation pier, civilian property is poor, is not suitable for large tracts of land popularization and use; At home, also have the development of civil earthquake alarm to occur, the part alarm is to utilize the mistiming of primary seismic wave and shear wave to design, but is not very big for the skyscraper applicability, and price is higher relatively; Also have some alarms by ground machine vibration work, be subjected to surrounding environment influence bigger, easily report by mistake, accuracy is low; Among the people also have some homemade alarms, but be simply equipped, and sensitivity is very low, is difficult to reach the effect of reporting to the police accurately.

Summary of the invention: the purpose of this invention is to provide the earthquake alarming device that a kind of existing the tinkle of bells has voice again, reminds people is in time taked the hedging measure when earthquake takes place, and reduces personal injury.

The object of the present invention is achieved like this: the difunctional earthquake alarming device of the tinkle of bells and voice is by rigid rod, flexible strand, the pendulum that dangles, steel ball, convex spherical guide rail, warning device housing, be formed by combining near switch, gusset, jingle bell, hand hammer, direct current generator and reduction gear, loudspeaker, intermediate relay I, intermediate relay II, accumulator, voice module, lighting bulb, ratchet, swing ratchet.

On the ceiling in room, hang the pendulum that dangles that a bottom has endoporus with flexible strand, the warning device housing is fixed on the ceiling in room on the flexible strand both sides with two rigid rods, lighting bulb is equipped with in warning device housing bottom surface central authorities, a gusset has been installed in the lighting bulb top, the gusset center fixed one near switch and a convex spherical guide rail, have an aperture at convex spherical guide rail top, its position is over against the hole of the pendulum bottom of dangling, steel ball is placed in pushes down on the aperture near switch, steel ball top just in time is buckled in the hole of the pendulum bottom of dangling, on the gusset around the convex spherical guide rail, have annular groove, two circle copper cash are arranged in the annular groove two edges, the annular groove bottom is placed polylith magnet and is covered with the full annular groove, accumulator is equipped with in warning device housing bottom left side, voice module, direct current generator and reduction gear are equipped with in the right side, jingle bell, loudspeaker, front end have two auxiliary reclays.

When earthquake takes place, the house can produce and rock, can drive immediately with ceiling and rock with the earthquake alarming device that rigid rod connects, the pendulum that dangles that is suspended on the ceiling with flexible strand also produces swing simultaneously, facts have proved that the amplitude of fluctuation that causes between rigid suspended thing and the flexible strand hanger is inequality, the latter is greater than the former, therefore with producing relative motion between the convex spherical guide rail in the dangle pendulum and the warning device of flexible strand suspension, the pendulum that dangles can drive steel ball and roll down to the annular groove of gusset from convex spherical guide rail top, the magnet of being placed by bottom portion of groove holds the copper cash of communication groove edge placement, this moment, the tinkle of bells warning circuit was connected, intermediate relay I normally opened contact closure, direct current generator starts, drive the reduction gear rotation and the ratchet on the output shaft is rotated, thereby drive the swing of swing ratchet, swing the hand hammer that is connected on the ratchet, when hand hammer is swung with the swing ratchet, knock jingle bell, send mechanical alarm sound.When steel ball when convex spherical guide rail top tumbles, near switch closure, voice alarm circuit is connected, intermediate relay II normally opened contact closure, voice module work, loudspeaker sends audio alert sound, lighting bulb begins illumination.

Because the difunctional earthquake alarming device of the tinkle of bells and voice adopts rigid rod to be fixed on the ceiling in room, and the pendulum that dangles adopts flexible strand to hang, the horizontal vibration sensitivity that the pendulum that dangles that flexible strand hangs produces shear wave, very little to the up-down vibration reaction that compressional wave produces, thereby horizontal shear wave dangle temporarily the pendulum and the convex spherical guide rail between relative motion takes place immediately, so the sensitivity of this tinkle of bells and the difunctional earthquake alarming device of voice is good, reaction velocity is fast.Report to the police and audio alert owing to adopted dual mutually noninterfere circuit to control the tinkle of bells respectively, also can in time report to the police even some breaks down, so the difunctional earthquake alarming device reliable operation of this tinkle of bells and voice.
