Embodiment Construction

[0012] In Fig. 1, the alarm indicator light (8), the alarm loudspeaker (11), and the voice board (12) are connected in parallel with the mercury switch (13) in series.

[0013] In the embodiment shown in Figure 2, the structure and working principle of the mercury switch (13): there is a dimple (2) in the center, on which mercury beads (1) are stored, and positive and negative contacts (3) are respectively set on its four sides , between each pair of positive and negative contacts (3) is an insulating partition (4); when an earthquake occurs, the shock wave makes the ground object vibrate, and the vibration of the ground object is transmitted to the mercury switch (13), then the mercury switch (13 ) vibrates and tilts, thereby driving the mercury beads (1) in it to leave the dimple (2) tilting and rolling to contact with the positive and negative contacts (3) on the side to open the current switch, and the current switch is opened Figure three The alarm system in is working. ...

Abstract

An alarmer capable of timely alarming earthquake includes a mercury switch, an ICB, batteries, a charger, a pilot lamp, an alarm loudspeaker, a phonetic plate sequently connected in a hard shell which is set in or on an indoor subject to accept earthquake wave fully and timely.

Description

Technical field [0001] The invention relates to an alarm device for warning the occurrence of an earthquake, in particular to an alarm device capable of timely and fully alarming people at the beginning of an earthquake. Background technique [0002] At present, there are two kinds of known earthquake prevention measures: the one is to warn the residents through the shock wave effect of the initial earthquake, if the shock wave of the initial earthquake is small or the people can't feel it in sleep, the residents will be affected by the destructive earthquake. The second is that when an earthquake first occurred, the earthquake monitoring network could remotely sense the occurrence of the earthquake, and then the earthquake monitoring network issued an alarm, and the occurrence of the first earthquake may have caused a disaster. Contents of the invention [0003] In order to overcome the deficiency that the existing earthquake prevention measures cannot timely and fully al...
