Abstract
The utility model relates to the teaching equipment field and the detection field, especially relates to an earthquake acousto-optic alarming device. The earthquake acousto-optic alarming device is characterized in that a bottom plate is provided; the bottom plate is provided with a support, and the support is provided with a conductive cycloid, which is hung vertically on the support; a lower part of the cycloid is provided with a counter weight, and a periphery of the cycloid is provided with a surrounding wire; a closed circuit can be formed by contacting the cycloid with the surrounding wire; an alarming device connected with the circuit is also provided; and the bottom plate is provided with a protruding bottom part. The earthquake acousto-optic alarming device is advantageous in that the structure is simple, the costs are low; no electric energy is consumed, when no alarm is given, therefore the device is environmental friendly and energy saving; by introducing the optic alarming function, the deaf-mutes can be aware of the earthquake; the device is suitable for the use and the production in households; compared to the professional earthquake precursor, the device is convenient and practical.
Description
Technical field
The utility model relates to instruments used for education field and field of detecting, relates in particular to earthquake acousto-optic alarm.
Background technology
China is between circum-Pacific seismic zone and the Eurasian seismic zone, is one of country that earthquake disaster is the most serious in the world.According to the measurement result that State Seismological Bureau announces, ruinous earthquake is taking place more than 5 grades for 20th century more than 3000 time in China altogether, reach 30 every year on average surplus time.Seismic event causes that building destruction mainly is the effect by seismic force, and namely longitudinal wave earthquake power pitches buildings, and destructive power is less relatively, mainly is to cause that the vertical structure of buildings is loosening.Shear wave earthquake power makes the buildings occurred level rock again subsequently, when inertia and seismic force surpass the bearing capacity of buildings, buildings is wrecked.Because the velocity of propagation of compressional wave is faster than shear wave, so people always feel " run earlier and afterwards shake " when meeting with earthquake.In order just to have arrived at compressional wave and can in time give the alarm to people during also no show of shear wave (buildings is not seriously damaged as yet), thereby win of short duration and valuable escape time for people.
The utility model content
The purpose of utility model: for provide a kind of simple in structure, fake cheaply, identification shakes earthquake acousto-optic alarm easily.
In order to reach as above purpose, the utility model is taked following technical scheme:
Earthquake acousto-optic alarm, it is characterized in that, comprise the chassis, on the described chassis support is arranged, sagging on the described support have a cycloid that can conduct electricity, and there is weight described cycloid below, and the contour that can conduct electricity is arranged around the described cycloid, described cycloid with enclose 3 and can constitute the closed circuit loop after contacting, also comprise the warning device of access in this loop.
The further technical scheme of the utility model is that described chassis is the chassis that protrude the below.
The further technical scheme of the utility model is that described chassis is circular.
The further technical scheme of the utility model is that described warning device is loudspeaker and/or warning lamp.
The further technical scheme of the utility model is that described support is three leg supports, and described contour is circle or spirality.
The further technical scheme of the utility model is that more than one screens is arranged on the described chassis, and described more than one screens is positioned on the different concentric circles in chassis, and described support can detachably be installed in screens.
The further technical scheme of the utility model is that described support is insulating material.
The further technical scheme of the utility model is that the weight of described cycloid below is cylindrical, and described cycloid is connected in this columniform center.
The further technical scheme of the utility model is that the profile on described chassis is shaped as zhou duicheng tuxing.
The further technical scheme of the utility model is that the profile on described chassis is shaped as paraboloidal.
Adopt as above the utility model of technical scheme, have following beneficial effect: simple in structure, cheap, consumed power not when not reporting to the police, environmental protection and energy saving.The introducing that light is reported to the police makes the deaf-mute that the possibility of knowing earthquake arranged, is highly suitable for to make in the family to use, and the earthquake prediction device of the specialty of comparing, convenient and practical.
Description of drawings
In order to further specify the utility model, further describe below in conjunction with accompanying drawing:
Fig. 1 is the plan structure synoptic diagram of utility model;
Fig. 2 is the main TV structure synoptic diagram of utility model;
Wherein: 1. screens; 2. support; 3. contour; 4. chassis; 5. weight; 6. cycloid; 7. switch; 8. loudspeaker; 9. warning lamp.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described, embodiment does not constitute restriction of the present utility model:
In conjunction with Fig. 1 and Fig. 2;
Earthquake acousto-optic alarm, it is characterized in that, comprise chassis 4, on the described chassis 4 support 2 is arranged, sagging on the described support 2 have a cycloid 6 that can conduct electricity, and there is weight 5 described cycloid 6 belows, around the described cycloid 6 contour 3 that can conduct electricity arranged, described cycloid 6 with can constitute the closed circuit loop after contour 3 contacts, also comprise the warning device of access in this loop.Cycloid 6 also can be spring, can measure compressional wave, can forecast this moment.
The chassis 4 that protrude for the below on described chassis 4.Described chassis 4 is circular.Described warning device is loudspeaker 8 and/or warning lamp 9.In case vibrations are arranged, the chassis 4 that protrude the below can be amplified vibrations, has strengthened the sensitivity of instrument.And then make cycloid 6 wave, and then make and loop works make warning device send alarm sound and warning radiance.
Described support 2 is three leg supports, and described contour 3 is circle or spirality.Its diameter can conveniently be adjusted.Realized that circular radius determines the digitizing of shockproofness.
More than one screens 1 is arranged on the described chassis 4, and described more than one screens 1 is positioned on the different concentric circles in chassis 4, and described support 2 can detachably be installed in screens 1.Support 2 is adjusted in the different screens 1, is different warning precision.
