Abstract
The utility model discloses an earthquake alarm instrument which relates to an electrical transmission audible signal device technique. The earthquake alarm instrument comprises a chassis (1), a bracket (3), a heavy hammer (5), a ring (4) and an alarm device (8) connected with the heavy hammer (5) and the ring (4), wherein, the bracket (3) is inserted in the chassis (1); the heavy hammer (5) is hung on the bracket (3); the ring (4) is fixed to bracket (3); the alarm device (8) is connected with the heavy hammer (5) and the ring (4). The utility model can send out alarm signals when small earthquake occurs and before a big earthquake occurs, so indoor persons can escape and shelter immediately.
Description
The utility model belongs to the technical field of the telltale of listening of electricity consumption transmission.
Report according to a large amount of relevant earthquake knowledge aspects, all destructive earthquakes, before earthquake except that having earthquake sounds, the flash of light preceding an earthquake and various animals and plants change, before all showing as shake slight earthquake is arranged, but people are often imperceptible, have only when big and shake temporarily, and people just feel, but when being with evening, thereby the chance that makes the people lose many escapes and hide.
When providing a kind of little shake before big shake is arrived, the purpose of this utility model sends the earthquake alarm of warning to people.
This earthquake alarm comprises base, and support is housed on base, top at support is fixed with tinsel, has hung weight in lower end wiry, is fixed with ring with the weight equal-height position on support, with tinsel and the lead that is connected of ring, the warning horn that is connected with power supply with lead.
Because lead and tinsel and ring link to each other, therefore when slight earthquake took place, weight was promptly swung, and makes weight and loop contacts, thereby the power supply of connection alarm makes alarm send audible alarm, thereby made the instant escape of people and hide.
Below in conjunction with accompanying drawing the utility model is described in detail.
Earthquake alarm as shown in the figure, comprise circular base plate 1, on 1 side, chassis, level meter 2 is housed, be inserted in The One On The Chassis support 3, and support 3 is inverted U-shaped, the upper end is pressed in the tinsel 6 on support 3 tops with screw, be hung in the weight 5 of tinsel 6 lower ends, the becket of fixing with screw with weight 5 equal-height positions on support 34 with tinsel 6 and ring 4 two leads 7 that are connected, is connected on the loudspeaker warner 8 on two leads 7 and the power supply respectively.
Weight and becket are static with gapped at ordinary times, when slight earthquake takes place, because weight and tinsel are very sensitive, thereby the weight swing contacts with becket, thereby connect the power supply of loudspeaker warner, loudspeaker warner sends audible alarm, promptly flees from indoor or hides nearby morning thereby make indoor personnel, thus the injures and deaths of avoiding.
Claims (3)
1, a kind of earthquake alarm, comprise base (1), it is characterized in that on base (1), being equipped with support (3), be fixed with tinsel (6) on the top of support (3), hung weight (5) in the lower end of tinsel (6), go up with weight (5) equal-height position at support (3) and to be fixed with ring (4), with tinsel (6) with encircle the lead (7) that (4) are connected, the alarm (8) that is connected with power supply with lead (7).
2, earthquake alarm according to claim 1 is characterized in that on base (1) side level meter (2) being housed.
