Problems solved by technology
The utility model utilizes the working principle of the single pendulum, that is, through the shaking of the pendulum of the instrument just after the earthquake occurs and before the main shock arrives, the alarm circuit is connected, and the sound and light signals are issued to give an alarm; it connects both ends of the trigger signal of the electronic alarm Connect the wire with the pendulum and the conductive strip separately. Since the conductive strip and the wire are fixed on the suspension plate in parallel, and there are conductive sliders that slide up and down on the conductive strip, there are too many electrical connection points, which are often affected by poor contact. Its functions are brought into play; and because it lacks the specific design of its mechanical parts, the utility model lacks a carrier and is difficult to implement

The present invention provides a mono-pendulum type earthquake alarming instrument which comprises an electronic alarm and a lead with pendulum. The mono-pendulum type earthquake alarming instrument is characterized in that: a casing is designed, the casing is formed by the match of a casing cover and a base plate, two ends of a triggering signal of the electronic alarm connect with a conductive plate and the lead with pendulum respectively, wherein, the conductive plate is provided with a centre hole; the conductive plate is fixed on a gap bridge of the casing cover, one end of the lead withpendulum is fixed on the top end of the casing cover and is overhung on the centre of the centre hole of the conductive plate. The mono-pendulum type earthquake alarming instrument has advantages of scientific design, reasonable structure, high sensitivity, low cost and strong practicability, which provides a simple equipment for sending out an early alarming signal before majorearthquake.
Description
Technical field [0001] The invention relates to an earthquake warning device. Background technique [0002] Chinese patent ZL200720018296.5 discloses a wall-mounted simple earthquake alarm, which is characterized in that an electronic alarm is installed on a suspension board, and both ends of the trigger signal of the electronic alarm are connected to a wire with a pendulum and a conductive strip. The wire is hung on the upper part of the suspension board. The conductive strip and the wire are fixed on the suspension board in a parallel direction. There is a conductive slider that can slide up and down on the conductive strip. The wire passes through the hole of the conductive slider. In the center of the hole. Through the circuit of the electronic alarm, an electronic switch can be controlled to automatically turn on the light. When an earthquake occurs, the light is automatically turned on to prevent people from finding the light switch in a panic and discrediting behavior. T...
