Abstract
The utility model relates to an earthquake alarm with high sensitivity, which comprises a ball seat, a copper ball and a high-decibel alarming integration block. The earthquake alarm with high sensitivity is characterized in that the lower part of a box body (1) is provided with an insulated baffle plate (3), the ball seat (4) is fixedly arranged on the baffle plate, the upper part of the ball seat is cylindrical, the bottom of the ball seat is made of copper or graphite, the periphery of the ball seat is provided with a bowl-shaped fence (5), the bottom of the fence and the bottom of the ball seat form an arc-shaped groove (6), a gap (7) is arranged between the fence and the ball seat, and the top end of the ball seat is provided with the copper ball (8). The utility model overcomes the defect that an alarm at present can be out of action because of surface oxidation after a long time, and has various advantages of good oxidation resistance, large contact area, high sensitivity and simple manufacturing process.
Description
Technical field
The utility model relates to the earthquake alarming device field, a kind of more precisely earthquake Alarm that can report to the police immediately that utilizes Metal Ball, deep-slotted chip breaker design.
Background technology
Earthquake is that the Nature destroys the most serious a kind of disaster to the mankind, and ruinous earthquake occupies second of city potential safety hazard.The miserable sight of China's Tangshan earthquake, Wenchuan earthquake, people remember clearly so far.Accurate forecast can't be made to earthquake in countries in the world before shake, earthquake comes interim, and people's reaction is not come, and especially at dead of night, waits when reacting the room that collapses, room, and people's lives and properties have been caused heavy losses.At present, be subjected to the threat of earthquake for fear of people's life, numerous household seismic warning devices occur successively, and in theory, these devices are feasible fully, but because the probability of happening of earthquake is very low, 1 year, 2 years, 10 years, 8 years in addition a lifetime this area can not take place yet, present earthquake Alarm generally all adopts steel ball, copper-clad plate or copper ring, wire producing, long surface oxidation of time one can be ineffective.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of antioxygenic property good, the high sensitivity earthquake alarm that contact area is big.
The purpose of this utility model adopts following technical measures to realize: a kind of high sensitivity earthquake alarm, by ball seat, copper ball, high-decibel warning integrated package is formed, it is characterized in that: on the box body made from transparent plastics or organic glass, a lid is arranged, box body bottom dress insulating barrier, ball seat fixedly is housed on the dividing plate, ball seat is that top is cylindrical, make with copper or graphite the bottom, one bowl-shape shape fence is arranged around the ball seat, the fence bottom forms an arc groove with the ball seat bottom, its camber ratio copper ball slightly larger in diameter, both combined closely when ball was fallen, and increased contact area, had one between the two at interval, tee top is equipped with copper ball, on the box body bottom faces loudspeaker is housed, power switch, box body is equipped with battery in the bottom, high-decibel warning integrated package, lead joins respectively with at the bottom of the ball seat and at the bottom of the fence, high-brightness LED lamp is housed on the box body surface, and lamp has transparent casing outward.
Remarkable result of the present utility model: owing to adopt copper to make spheroid and make base with copper or graphite, antioxygenic property is good, and contact area is big, and is highly sensitive, and manufacture craft is simple.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is an electric principle assumption diagram of the present utility model.
Below in conjunction with accompanying drawing the utility model is further elaborated.
Embodiment
Referring to figure, one lid 2 is arranged on the box body made from transparent plastics or organic glass 1, box body bottom dress insulating barrier 3, ball seat 4 fixedly is housed on the dividing plate, ball seat is that top is cylindrical, make with copper or graphite the bottom, one bowl-shape shape fence 5 is arranged around the ball seat, the fence bottom forms an arc groove 6 with the ball seat bottom, its camber ratio copper ball slightly larger in diameter, and both combined closely when ball was fallen, increase contact area, one interval 7 is arranged between the two, and tee top is equipped with copper ball 8, and loudspeaker 9 is housed on the box body bottom faces, power switch 10, box body is equipped with battery 11 in the bottom, high-decibel warning integrated package 12, lead 13 joins respectively with at the bottom of the ball seat and at the bottom of the fence, and high-brightness LED lamp 14 is housed on the box body surface, and lamp has transparent casing 15 outward.
