Abstract
The utility model relates to an earthquake alarm which comprises a bracket capable of being fixedly connected with a wall. A supporting body is fixedly arranged above the bracket, a push rod is arranged in the supporting body, the top end of the push rod slightly extends out of the top end of the supporting body, and the top end of the supporting body is provided with a heavy round ball which presses against the top end of the push rod and is arranged on the top end of the supporting body; the push rod is linked with a microswitch of a control circuit which also comprises an alarm circuit, and the microswitch is connected with the alarm circuit and also controls the alarm circuit. The earthquake alarm can perceive the shake of the wall through the bracket and further transmit the shake to the heavy round ball positioned on the top end of the supporting body when an earthquake generates so as to enable the heavy round ball to fall down from the top end of the supporting body and release the pressure on the push rod, and the push rod also drives the microswitch to operate to control the work of the alarm circuit, thereby the purpose for alarm is achieved.
Description
Technical field
The utility model relates to a kind of earthquake Alarm.
Background technology
The forecast of earthquake still is the science difficult problem in the world at present, information when " seismograph " of a weighing apparatus invention in 132 years Christian eras can detect the earthquake generation, what his " seismograph " utilized is the principle of " freely falling body ", and practice explanation serviceability is reliable.But because it is complicated to make system, the expense costliness needs special-purpose place, special messenger's monitoring, does not have reasons such as modern sound equipment electric light is direct, can not popularize so far and is utilized by broad masses.
The utility model content
The utility model has overcome above-mentioned shortcoming, and a kind of earthquake Alarm simple in structure, easy to use, widely used is provided.
The technical scheme in the invention for solving the technical problem is: a kind of earthquake Alarm, comprise the carriage that can be connected with wall mounted, described carriage upper fixed is provided with supporter, be provided with push rod in the described supporter, the top of supporter is stretched out on the top of described push rod slightly, the top of described supporter is placed with the heavy ball, described heavy ball is pushed down the top of described push rod, be positioned over the top of described supporter, microswitch interlock in described push rod and the control circuit, also comprise a warning circuit in the described control circuit, described microswitch connection is also controlled described warning circuit.
Described carriage can comprise the vertical wall board and the pallet of level, and described wall board is at right angles fixedlyed connected mutually with pallet.
Described supporter can be hollow structure, and described control circuit places the hollow structure of described supporter.
Can comprise the ac power input end, rectification circuit, mu balanced circuit and the warning circuit that connect successively in the described control circuit.
Described ac power input end also can be parallel with the coil of a relay, a normally opened contact of described relay is connected between described mu balanced circuit and the warning circuit, another normally closed contact is connected with a Battery pack, and the circuit after the series connection is in parallel with the input end of warning circuit.
Described warning circuit can comprise audible alarm circuit and luminous warning circuit.
The utility model can be when earthquake takes place, by rocking of described carriage perception wall, and then transfer vibrations to the described heavy ball on described supporter top, the heavy ball is fallen from the top of supporter, release is to the pressure of described push rod, simultaneously described push rod drives the microswitch action, controls warning circuit work, reaches the purpose of warning, the utility model is simple in structure, be widely used, easy for installation, be adapted to uses such as family and public place.
Description of drawings
