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 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 to lean on the alarm of ground machine vibration work, receive surrounding environment influence bigger, the easy wrong 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 objective of the invention is to realize 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, form 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 with two rigid rods on the flexible strand both sides, 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 have an aperture near switch and a convex spherical guide rail 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, and on the gusset around the convex spherical guide rail, has annular groove, and 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, voice module are equipped with in warning device housing bottom left side, and direct current generator and reduction gear, jingle bell, loudspeaker are equipped with in the right side, and front end has two auxiliary reclays.

When earthquake took place, the house can produce and rock, and can drive immediately with ceiling to rock with the earthquake alarming device that rigid rod connects; The pendulum that dangles that is suspended on the ceiling with flexible strand simultaneously also produces swing, facts have proved that the amplitude of fluctuation that causes between rigid suspended thing and the flexible strand hanger is inequality, and 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 tumble to the annular groove of gusset from convex spherical guide rail top, by the copper cash of the magnet attracts communication groove edge placement of bottom portion of groove placement; This moment, the tinkle of bells warning circuit was connected; The intermediate relay I normally opened contact is closed, and direct current generator starts, and drives reduction gear and rotates and make the ratchet rotation on the output shaft; 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, the intermediate relay II normally opened contact is closed, 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 the flexible strand suspension; The pendulum that dangles of flexible strand suspension is responsive to the horizontal vibration that shear wave produces; Up-down vibration reaction to compressional wave produces is very little, thereby horizontal shear wave comes to dangle temporarily and between pendulum and convex spherical guide rail 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.

Description of drawings: the present invention is further specified below in conjunction with accompanying drawing and embodiment.
