Abstract

The invention relates to a pendulum mass-spring hammer head type urban public automatic impending earthquake warning system, which is mainly mixed by groups of various pendulum masses, and uses the collision generated by the shaking of a long rod and a spring hammer head with surrounding fixed contact terminals as the warning datum, belonging to the shaking trigger circuit closing type impending earthquake warning technology. When in ready, a warning circuit is off, and the warning circuit is closed to send out warnings and spread signals to surrounding towns when in operation. The invention can be independently used as a public automatic impending earthquake warning system of a county town, a town and a county, and can simultaneously send out various warnings. If the automatic warning device is installed on one town, warning can not be sent out when the pendulum mass is still, namely that buildings can never fall down in the state. And the warning device sends out warnings when the pendulum mass starts to shake, which means the surface shaking, as the premonition of an earthquake. Thus the automatic warning device can be installed to evacuate people in advance before people directly feel the earthquake.

Description

A kind of pendulum and spring ram public earthquake alarm for city and town
One, technical field
The present invention relates to a kind of pendulum and spring ram public earthquake alarm for city and town, it adds rocking of spring tup with plug in stock under many groups pendulum and the collision of fixed contact generation on every side is the warning benchmark, belongs to the imminent earthquake alarm technique that rocks the trigger circuit closo.Form because of this alarm is mixed by many groups of multiple pendulums, can tackle the imminent earthquake ripple from different azimuth and different-waveband, particularly its number of times that can rock along with the face of land and giving the alarm does not promptly need to add adjusting again and can implement auto-alarm-signal keying device continuously.Use with the independent public earthquake automatic alarm as a county town or small towns and village of activation, the earthquake automatic alarm net that also can form an area uses.
Two, background technology
The time by now, though it is more also very advanced to be used for the instrument kind of prediction about imminent earthquakes and monitoring, but because people are to the origin cause of formation of earthquake with select monitoring place etc. to lack knowledge and skills, difficulty can be made accurate forecast before violent earthquake was arrived, everybody can only lean on the good fortune of destiny temporarily when violent earthquake comes, violent earthquake 80,000 people in Wenchuan are wrecked to be exactly a miserable example, and consequently, people urgently wish to have a kind of public alarm facility.
Three, summary of the invention
Rocking ripple because of the destructiveness of earthquake also is to be come by little increase, and to rock each time of ripple also inequality on the face of land of imminent earthquake, even the earthquake that has even shake the preceding face of land and can occur rocking several times, so, the present invention seeks to design a kind of pendulum and spring ram public earthquake alarm for city and town, the number of times that it can rock along with the face of land and giving the alarm does not promptly need to be regulated again and can implement auto-alarm-signal keying device continuously.This alarm can independently use as the public automatic imminent earthquake warning system in a county town and small towns and village, and the earthquake automatic alarm net that also can form an area uses.And can be used as automatically the transmitter of cities and towns spreading and propagation imminent earthquake alerting signal towards periphery again.And this alarm can also send single the kind and multiple imminent earthquake alarm, makes the common people in earthquake region can get the face of land and rocks alarm, common evacuation alarm, emergency evacuation alarm etc.Also can solve people preferably and begin in advance before the earthquake to evacuate directly not feeling, evacuate in advance simultaneously and mean that also egress door is not opened by distortion easily yet, it is minimum to make earthquake cause injures and deaths to reduce to.
For achieving the above object, the solution that the present invention takes is: a kind of pendulum and spring ram public earthquake alarm for city and town, it is mainly mixed by many groups of multiple pendulums and forms, and produce collision with rocking of stock and spring tup with fixed contact on every side and be the warning benchmark of each group, genus rocks the imminent earthquake alarm technique of trigger circuit closo.Warning circuit is for disconnecting when awaiting orders, and during enforcement, reports to the police and cities and towns transmitting signal towards periphery thereby warning circuit produces closed sending.
Feature and advantage of the present invention are that this alarm can send single the kind or simultaneously multiple imminent earthquake alarm, and people can be evacuated and the multiple different information of emergency evacuation usually.It is simple in structure, and all functions all belong to general physics, long service life.And pendulum stock and spring tup rock warning reference range scalable, rock misleading or the false declaration that is produced a little less than eliminating.When the pendulum of this alarm can not give the alarm when static, promptly in this state, can never produce buildings and cave in without foundation.When if pendulum begins to rock alarm and gives the alarm, be exactly that the face of land is in rocking, also before the earthquake million.Particularly working as earthquake in the late into the night comes interim, the people that the alarm sound of this alarm can not only wake up in the sleep hasten to flee from, and evacuation in advance means that also lighting lamp is also for normal, avoid crowded mutually from pitch-dark flurried evacuation, not opened easily by distortion with egress door road early, it is minimum to make earthquake cause injures and deaths to reduce to.
