Abstract
The utility model relates to a novel earthquake alarm device which comprises a vibration circuit breaker and an alarm circuit arranged in a shell; the vibration circuit breaker comprises at least foursteel columns and two conductive films; the steel columns are overlaid on one conductive film, and the other conductive film is arranged under the first steel column. The novel earthquake alarm device has the advantages of reasonable design, high earthquake alarm sensitivity and good reliability, can well remind the people of avoid in time, so as to reduce and prevent the harm and economic loss caused by the earthquake.
Description
Technical field:
Technical scope is observed and predicted in the shake of the utility model possession, relates to a kind of earthquake Alarm.
Background technology:
Earthquake is a kind of disaster, and precipitate violent earthquake often causes a large amount of casualties and enormous economic loss.For implementing the prediction of earthquake, country has set up huge surveillance network, and many common people also are provided with earthquake Alarm, for enormous function has been brought into play in prediction, the warning of earthquake.Earthquake Alarm kind of the prior art is a lot, though all fairly simple, sensitivity is low mostly, and poor reliability is difficult to accomplish timely warning, and the prompting people hide the purpose of earthquake disaster fast.And can not realize that the power failure that causes because of earthquake reports to the police.
Summary of the invention:
The purpose of this utility model provides a kind of novel earthquake Alarm, in order to overcome the existing above-mentioned drawback of prior art earthquake Alarm effectively.The purpose of this utility model realizes with following technical scheme: it is made of with the warning circuit two parts that are installed in housing and the housing a vibrations tripper, said warning circuit has successively transformer BG and the rectifier DL that connects with AC power, and the positive terminal of rectifier DL connects a K switch
1, K switch
1The other end divide four joints, joint connects relay J

1Second group of contact J
1-2Normally closed contact connect; J
1-1Moving contact and alarming horn LB connect J
1-2The moving contact K switch of connecting
2Back and relay J
2Second group of contact J
2-2Normally closed contact connect J
2-2Moving contact connect alarming horn LB, J
2-1Normally opened contact resistance in series R and pilot lamp RD after connect relay J
2The other end; Said vibrations tripper is made up of at least four steel columns and two conducting strips, and two conducting strips are negative pole and the relay J by flexible circuit conductor and rectifier DL respectively
2The other end connect, steel column is stacked on the conducting strip, another conducting strip be placed on several first steel columns below.
The utility model is reasonable in design, and its earthquake alarm is highly sensitive, and good reliability can be pointed out people preferably, in time hides, thereby alleviates and avoid injury and the economic loss that earthquake causes.
Description of drawings:
Accompanying drawing is electric principle of the present utility model and structural representation
Embodiment:
Accompanying drawing has provided a specific embodiment of the present utility model, with reference to the accompanying drawings, 2 is warning circuits among the figure, can be installed in housing and the housing, this warning circuit has successively transformer BG and the rectifier DL that connects with AC power, and the positive terminal of rectifier DL connects K switch
1, K switch
1The other end divide four joints, joint connects relay J
1, second joint connects relay J
1Second group of contact J
1-2Normally opened contact, the 3rd joint connects relay J
2, the 4th joint connects relay J
2First group of contact J
2-1Moving contact; Rectifier DL negative pole end connects relay J
1The other end and relay J
1First group of contact J
1-1Normally opened contact, J
1-1Normally closed contact connect the negative pole of direct supply V, the positive pole of direct supply V and relay J
1Second group of contact J
1-2Normally closed contact connect; J
1-1Moving contact and alarming horn LB connect J
1-2Moving contact tandem tap K
2Back and relay J
2Second group of contact J
2-2Normally closed contact connect J
2-2Moving contact connect alarming horn LB, relay J
2First group of contact J
2-1Normally opened contact resistance in series R and pilot lamp RD after connect relay J
2The other end; The 1st, the vibrations tripper, this device is made up of 6 steel column 1-3 and two conducting strip 1-1 and 1-2, and conducting strip 1-1 is by the negative pole connection of flexible circuit conductor and rectifier DL, conducting strip 1-2 and relay J
2The other end connect, 6 steel columns are stacked on the conducting strip 1-1, another conducting strip 1-2 be placed on several first steel column 1-3 below.During use, the housing that warning circuit is installed is positioned over the indoor appropriate location of being convenient to operate, will shakes tripper and place the quiet place to fold, plug in then, open K switch
1And K
2, pilot lamp is bright, at this moment, then is in normal operating conditions.When earthquake took place, the vibrations that seismic event produces made the steel column 1-3 of vibrations tripper rock to collapse to open circuit relay J
2Lose power supply, its second group of contact J
2-2Moving contact and normally closed contact connect, alarming horn LB circuit turn-on, thus implement to report to the police.When earthquake causes grid power blackout, relay J
1And J
2All lose power supply, relay J
2Second group of contact J
2-2Moving contact and normally closed contact connect relay J
1Two groups of contact J
1-1, J
1-2Moving contact all connect with normally closed contact, alarming horn LB circuit is also implemented to report to the police by direct supply V power supply conducting.If belong to the normal warning that has a power failure and cause, but people's off switch K
2, with alarm release.When people go out, can be with switch
2Close, can not in time remove because of the normal warning that causes that has a power failure avoiding.
