Description

A kind of earthquake Alarm

Technical field

The utility model relates to the earthquake alarming equipment technical field.

Background technology

Earthquake Alarm is alerting signals such as sound, light are sent in a kind of earthquake when taking place to people a warning device.As everyone knows, earthquake is the most fearful, least predictable a kind of in the human disaster that meets with, cause heavy losses often for human lives and properties, and earthquake often occurs in the late into the night that people sleep soundly, people often can not get any warning and prompting, huge disaster just comes suddenly, and people are felt simply helpless.The special violent earthquake of Wenchuan, Sichuan in 2008 burst, it really is bolt from the blue, suddenly very dizzy, mountains collapse and the earth crack up, highway bridge damage, interruptions such as traffic, communication, electric power, tap water, house collapse, become ruins between the momentariness of village, city, ten hundreds of people have lost life, and earthquake has caused tremendous loss to the country and people.According to the data introduction, when earthquake takes place, the house at first is to produce to rock, even the sharpest earthquake, rocking to collapse from the house also needs the regular hour, from several seconds to one minute or longer, if can know the generation of earthquake when beginning to occur rocking in the house, impel people to leave building as early as possible, hide to harbor, perhaps take other defence measure, will reduce a lot of casualties and economic loss.Existing national earthquake early-warning system need certain hour again when ordinary people is circulated a notice of when detecting earthquake information, and earthquake takes place extremely rapidly, and ordinary people is just received earthquake information often after the earthquake, lose unavoidable.Existing earthquake Alarm, the complex structure that has involves great expense; The defective that has owing to design, sensitivity is unadjustable, and alerting signal is discontinuous, is difficult to really play the effect of warning when people sleep soundly at dead of night, occupy above reason, and existing earthquake Alarm is seldom applied in ruck.

The utility model content

The purpose of this utility model be to provide a kind of volume little, in light weight, put flexibly, highly sensitive and scalable, alerting signal is not interrupted continuously, earthquake pre-warning is accurate, simple in structure, cheap, be suitable for the local earthquake Alarm that uses in family, office space, school etc.

In order to solve the problems of the technologies described above, a kind of earthquake Alarm of the utility model, comprise outer container, earthquake sensing device and warning circuit, the sidewall of described outer container is provided with supply hub, emergency alarm bell and switch, and described earthquake sensing device and warning circuit are arranged in the outer container.Described earthquake sensing device comprises an insulating cylinder, be provided with the little cylinder of hollow insulation in the undersetting center of insulating cylinder, coboundary at little cylinder is provided with a metal ring plate, top cover center at insulating cylinder is provided with a through hole, a warning wire is set to be overhang in the insulating cylinder by through hole, the lower end of warning wire is connected with a taper gravity drop hammer, the tapering of taper gravity drop hammer overhangs in the metal ring plate, the upper end of warning wire is connected with the zero line of warning circuit, and the metal ring plate is connected with the contact A1 of relay by lead; Described warning circuit comprises relay, power transformer and rectifier bridge, is provided with one and connects lead between the contact B2 of relay and zero line.

Circular diameter is not less than the interior circular diameter of metal ring plate at the bottom of the awl of described taper gravity drop hammer.

The bonnet of described outer container is set to detachable removable cover.

The principle of work of the utility model earthquake Alarm is: earthquake Alarm is placed within doors, energized, when earthquake takes place, ground, house and the vibrations of various object are rocked, the outer container of earthquake Alarm rocks, and the taper gravity drop hammer is swung thereupon and contacted with the metal ring plate, and electric current is by relay contact A1---and A2 makes relay adhesive energized, other contact of relay, B1---the equal energized of B2, C1---C2 and D1---D2; When the metal ring plate was left in the backswing of taper gravity drop hammer, electric current is by relay contact B2---B1---, and A1 made relay still keep the attracting state energized, and earthquake Alarm works on.

The beneficial effects of the utility model: circular diameter is not less than the interior circular diameter of metal ring plate at the bottom of the awl of the utility model taper gravity drop hammer, guarantees that the taper gravity drop hammer can not fall into below the metal ring plate, thereby avoids the earthquake generation and earthquake Alarm does not have the phenomenon of response; The warning wire length scalable that is connected with the taper gravity drop hammer, control the degree of tilt that the taper gravity drop hammer contacts with the metal ring plate with this, therefore, thus can regulate the sensitivity of earthquake Alarm according to the structure, one-storey house or the building that whether are in earthquake-prone region, residential building and individual demand free adjustment lead length; The ingenious design of the utility model warning circuit, promptly between the contact B2 of relay and zero line, be provided with one and connect lead, make as long as earthquake one takes place, the swing of taper gravity drop hammer contacts with the metal ring plate, earthquake Alarm just work sends alerting signal, when the metal ring plate is left in the backswing of taper gravity drop hammer, therefore electric current does not interrupt, relay still keeps the attracting state energized, earthquake Alarm works on, for till turning off power supply, avoid alerting signal discontinuous up to the people, be difficult for the defective that causes that people pay close attention at dead of night.The utility model volume is little, in light weight, put flexibly, and is simple in structure, cheap, is suitable for using in that family, office space, school etc. are local, has good social benefit and economic benefit.
