Embodiment Construction

[0018] exist figure 1In the figure a on the left is the circuit diagram, as shown in the figure, a tubular mercury switch (4 ) and sensitivity switch (6), emergency knob switch (7), sound alarm release switch (8), interlock contactor (9), interlock contactor moving-on contact (10), moving-off button (11) , sound alarm (12), radio alarm (13), rechargeable battery (14), hand generator (15) and other components are electrically connected through wires, wherein the interlock contactor (9), interlock contactor The movable closing contact (10) and the movable breaking button (11) are electrically connected, and are combined with the mercury switch (4) and the sensitivity switch (6) circuit to form a parallel interlocking circuit. When an earthquake occurs, even if the mercury switch (4) It is only disconnected after the momentary vibration conduction once, and the parallel interlock circuit can also make the sound alarm (12) and radio alarm due to the action closure of the interloc...

Abstract

The invention discloses an earthquake alarm device capable of effectively generating high-decibel audible alarm and radio-wave alarm when an earthquake disaster happens. Elements such as a mercury switch or a heavy hammer switch, a sensitivity switch, an emergency knob switch, an audible alarm elimination switch, an interlocking contactor, an interlocking contactor normally-open contact, a normally-closed button, an audible alarm, a radio-wave alarm, a charge battery and a hand generator are electrically connected through lead wires and then are combined with elements such as an alarm housing, an alarm base, a resonance supporting spring and a radio-wave emission antenna in sequence respectively to form a mercury switch earthquake alarm device or a heavy hammer switch earthquake alarm device.

Description

technical field [0001] The invention relates to an earthquake alarm device capable of effectively issuing high-decibel sound alarms and radio wave alarms when earthquake disasters occur. In particular, it is an earthquake alarm device that can cause sudden earthquake disasters at night or when people are sleeping, effectively issue disaster warnings for sleeping people and can accurately indicate the rescue location of victims after the earthquake. Background technique [0002] At present, when an earthquake disaster breaks out, it is difficult for people to feel the earthquake disaster in time, especially when a disaster occurs late at night or when people are asleep, if they cannot perceive the sudden earthquake disaster in time, people will not be able to avoid it in time and cause serious loss. Contents of the invention [0003] In order to overcome the current shortage that people cannot perceive sudden earthquake disasters in time in the middle of the night or when ...
