Abstract

The utility model provides an alarm system for an earthquake, which realizes automatic alarm when an earthquake occurs. The utility model is composed of a vibration sensor, a triggering rod, an alarm sound generator, etc. The utility model is characterized in that a steel ball is arranged on a tray and does not fall down without vibration; when the earthquake occurs, the ground shakes, the steel ball falls down, and the alarm is triggered to send out alarm sounds to tell or wake up people who sleep. Effective measures are rapidly taken for avoidance of earthquakes and self help by utilizing dozens of seconds before a major earthquake occurs. The utility model has the characteristics of simple structure, convenient operation, high sensitivity, practicability, etc.

Description

Earthquake Alarm

The utility model relates to the warning articles for use, especially a kind of automatic earthquake alarm of mechanical sounding.

Earthquake disaster is first of the various disasteies, can cause great loss to people's lives and properties.But, up to the present, human forecast to earthquake, it is accurate and effective to resemble weather forecast, and this humanly is difficult to take timely, effective strick precaution to earthquake with regard to making, according to the statistics of former generation earthquake and scientist's explanation, earthquake mostly occurs in night (because lunar gravitation influence), because this moment people are in and sleep soundly, if the alarm free device, just can't take emergent effective measures shock-absorbing, thereby cause harm just to be difficult to avoid the human life.Therefore, develop a kind of automatic earthquake alarm and just seem necessary, but up to the present, domestic still desirable without comparison household earthquake warning device.

The purpose of this utility model provides a kind of alarm that can trigger automatically and sends a kind of warning device that sound equipment is reported to the police when earthquake begins to take place, be used for reminding or waking the people that sleep soundly, and adopts an effective measure rapidly, and shock-absorbing is saved oneself.

Technical solution of the present utility model is: earthquake Alarm: by shock sensor, guide-track groove, frizzen and alarm sound generator constitute.Structure as shown in Figure 1

Said shock sensor is made up of the screw (3) of steel ball (1), plastic pallet (2) and the fastening pallet of spheroidal, the surface of pallet is slightly concave, the surface up, horizontal positioned, steel ball are placed on above it, do not fall down when not shaking, the bottom of pallet and a spheroid connect into an integral body, spheroid can be gone up universal rotation at basetray (4), makes tray surface maintenance level, and screw is used for fixing pallet.

Said guide-track groove is made up of plastic pallet base (4), conduit (5) and steel ball outlet (6), base and fixed support (17) fuse, and the conduit upper port is big, and the bottom is young to be funnel-form, catheter diameter is more bigger than steel ball, is used for accurately guiding steel ball to fall to hitting frizzen.

Said frizzen (7) utilizes ready-made mechanical alarm clock jingle bell control lever, be fixed with the preceding bar (14) of hammer of the usefulness of ringing a bell on the bar, bar (8) behind the hammer of location usefulness, swing span (13) and frizzen button (18), wherein the preceding bar of hammer has connected the bell clapper (15) of the usefulness of ringing a bell again.

Said alarm sound generator utilizes ready-made mechanical alarm clock part, and clockwork spring (10), gear (11), transmission gear (12), frizzen (7), washer (9) and steel bell (16) are installed between two fixed supports (17).

The said steel ball of the utility model is placed on tray surface, can not fall down when not shaking, and when earthquake took place, vibrations made steel ball weightlessness and fall down from pallet, and it vertically hits the pressure frizzen along conduit, makes the alarm clock sounding alarm.

The utility model is owing to adopted shock sensor that the carrying out of earthquake monitored automatically, and can trigger automatically at the initial stage that earthquake takes place and report to the police, thereby guaranteed in time to wake heavy sleepers' shock-absorbing of taking measures rapidly, it can't accurately forecast and not have the present situation of earthquake siren for household to present earthquake, play shockproof combating a natural disaster, the effect for people provide the chance of saving oneself has simple in structure simultaneously, easy to use, advantages such as practicality.

Below in conjunction with accompanying drawing the utility model is illustrated:

Fig. 1 is the earthquake Alarm structural representation

Fig. 2 is the pallet synoptic diagram of spheroidal for the surface

Fig. 3 is the steel ball synoptic diagram on plane for the bottom surface

As shown in Figure 1: plastic pallet base (4) is fixed on the fixed support (17), and make the vertical component of conduit (5) aim at frizzen (7), fully-wound (10), frizzen button (18) is up pressed, hammer back bar (8) is stuck on the washer (9), swing span (13) can't be swung, steel bell this moment (16) is noiseless, again complete machine is fixed on the wall, steel ball (1) is placed on pallet (2) surface, regulate pallet holding tray surface level, steel ball is not rolled down, screw holding screw (3) then, pallet is fixed, this moment, alarm was on the alert.Earthquake can produce compressional wave and shear wave when taking place, longitudinal wave motion is fastest, it arrives ground than shear wave elder generation in general tens seconds in advance, compressional wave is little to building destruction, and the destructiveness of shear wave is greatly, therefore, and when earthquake takes place, compressional wave at first arrives ground and makes the house vibrations, steel ball just tumbles from pallet, and it vertically hits frizzen along conduit (5), and frizzen is pressed down, hammer back bar (8) just breaks away from washer (9), swing span is not stuck, at clockwork spring (10) and gear (11), (12) under the effect, swing span begins swing, it drives preceding bar (14) of hammer and bell clapper (15) swing, bell clapper impacts the warning of sounding of steel bell, after people hear chimes of doom, utilizes tens times in second before shear wave arrives, hide rapidly to the safe place, shock-absorbing is saved oneself.

Shock sensor is except the steel ball that adopts the surface to be the pallet of slightly concave and spheroidal cooperates, also can adopt the surface to be the pallet (Fig. 2) of spheroidal and steel ball (Fig. 3) that the bottom surface is plane (or slightly concave) cooperates, this moment the tray bottom can be directly and base be connected and fixed, need not universal rotation, during work the baseplane of steel ball is placed on the ball top of pallet, and making it steady, steel ball fell down to trigger from pallet ball top and reports to the police when earthquake took place.

Claims

1, a kind of earthquake Alarm that is made of shock sensor, guide-track groove, frizzen and alarm sound generator is characterized in that:

(1) described shock sensor comprises: steel ball (1), pallet (2) and holding screw (3).

(2) described guide-track groove comprises basetray (4), conduit (5) and steel ball outlet (6), and the internal diameter of vertical pipe is more bigger than steel ball.

(3) be fixed with on the frizzen (7): bar (14), hammer back bar (8) and button (18), frizzen can move at axis direction before swing span (13), the hammer.

(4) described alarm sound generator comprises: clockwork spring (10), gear (11), (12), bell clapper (15) and steel bell (16) constitute.

2, earthquake Alarm according to claim 1, it is characterized in that: steel ball (1) makes spheroidal or ball by the bigger object of proportions such as steel or iron or copper or lead but there is the individual plane shape of (or being slightly concave) bottom surface, pallet (2) surface is slightly concave or spheroidal, place up on the surface, the bottom of pallet is spherical in shape and can universal rotation on base, so that tray surface keeps level.

3, earthquake Alarm according to claim 2 is characterized in that: steel ball is placed on the tray surface, can not fall down when not shaking, and when vibrations, steel ball rolls down or slides because of weightless, leans on the gravity of steel ball directly or indirectly to go to trigger alarm equipment alarm.
