Abstract
The invention discloses an earthquake alarm which mainly comprises an inductor, a relay, a main control switch, an alarm loudspeaker, an alarm indication lamp and a power supply which are connected in series, wherein the inductor is fixed on a ceiling of a building through the top surface of the inductor or on a wall through the side surface of the inductor. In a static condition, a metal disc and a concave round cavity are both in a balance state, a gap is formed between the metal disc and the concave round cavity, namely the metal disc is not in contact with the concave round cavity, and the two lead-out wires of the inductor are in a disconnected state; when the building quakes or deflects with a certain amplitude, the metal disc and the concave round cavity swing oppositely and come into contact with each other, and the two lead-out wires of the inductor are in a connected state. The earthquake alarm can send out an alarm so as to win escape time for people before a destructive earthquake occurs or when a house collapse is possibly caused due to a violent explosion.
Description
Technical field
The present invention relates to a kind of prior-warning device, be specifically related to a kind of earthquake Alarm.
Background technology
Show according to relevant expert's research and recent phenomenon, the present earth has progressed into the earthquake frequent phase, and earthquake is for will as the blowing and raining in daily life us.Annual about generation more than 500 ten thousand secondary earthquakes on the earth, that is, will there is secondary earthquake up to ten thousand in every day.Just domestic, earthquake disaster is very serious, the compatriot that the Wenchuan violent earthquake in such as China in May, 2008, the cajaput violent earthquake in March, 2009 and the Yaan earthquake on April 20th, 1 cause us a lot of lives in misery, and makes the lives and properties of people be subject to huge loss.
According to statistics, in 20th century, existing more than 50 ten thousand people of China die from earthquake, account for the half of the whole world earthquake toll same period.One, we are known today is that a lot of earthquake occurs in people's lunch break or has a rest evening in the time period of sleep, a lot of people also dies from earthquake disaster under unconscious sleep state, and the time of nearly 1/3rd that has in life of people is spent in sleep; Its two, when earthquake, people are in inside the inside or office buildings, after human body instinct experiences violent seismaesthesia, basic not free to flee from, are originally trapped in the inside lethal when building collapsing.As long as sometimes ten seconds time during coming earthquake required for escape, so the earthquake Alarm shifting to an earlier date the warning of a bit of time in order to the design that can avoid the coming trouble is a kind of is necessary.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of earthquake Alarm, its can before ruinous earthquake occurs or because of severity explode generation may cause house collapse time, send warning, strive for escape time to people.
For solving the problem, a kind of earthquake Alarm designed by the present invention, primarily of the inductor of mutually connecting, relay, master control switch, alarming horn, alarm lamp and power supply composition; Wherein
Inductor comprises casing, permanent magnet, 2 small balls, rosette and spill cylindrical cavities; Casing is an airtight square hollow housing, is made up bottom it of metal material; Wherein central authorities of being extremely vertically fixed on box inside top of permanent magnet, permanent magnet another extremely on be fixed with a small ball; Spill cylindrical cavity is the flat-shaped cylindrical or truncated cone-shaped cavity of hollow, and the center at spill cylindrical cavity top is provided with opening, and the bottom of spill cylindrical cavity is fixed on upper bottom box inside and the center of spill cylindrical cavity and is in central authorities bottom box inside; Rosette is suspended in the internal cavities of spill cylindrical cavity, and spill cylindrical cavity is looped around the periphery of rosette; The circle centre position of rosette is fixed with No. two small balls, and these No. two small balls stretch out from the opening part at spill cylindrical cavity top, and to be contacted by magnetic force with the small ball be fixed on permanent magnet and connect together, rosette equalizing suspension system is in spill cylindrical cavity; A small ball and spill cylindrical cavity are respectively drawn wire by one and are drawn, and are connected to the two ends of relay switch;
