Abstract
A domestic seismic alarm disclosed by the utility model includes a stand, a magnet a and a magnet b with opposite setting anode and cathode, wherein, a spring is suspended in the central of the stand top, the lower end section of the spring is connected to the magnet a, the magnet b is connected to the batteries through wires, and the loudspeaker is respectively connected to the batteries and spring through the wires. The domestic seismic alarm of the utility model has simple structure, convenient operations, high sensitivity and low prices.
Description
Technical field
The utility model belongs to the warning Instrument technology field, is specifically related to the earthquake siren for household that uses in a kind of suitable family.
Background technology
The instrument that is used at present to forecast earthquake and tests is a lot, but complex structure mostly, volume is very big, cost an arm and a leg, be not suitable for, and China is the country of an earthquake pilosity in domestic. applications, if it is untimely to forecast earthquake in average family, will threaten personnel component life.
Summary of the invention
The purpose of this utility model provides a kind of earthquake siren for household, is fit to family and uses, and is simple in structure, easy to operate, highly sensitive.
The technical scheme that the utility model adopted is, earthquake siren for household, comprise support, the central mounting of propping up top of the trellis has spring, also comprise magnet a and magnet b that both positive and negative polarity is oppositely arranged, the bottom of described spring is connected with magnet a, and described magnet b is connected with battery by electric wire, and loudspeaker is connected with spring with battery respectively by electric wire.
The beneficial effects of the utility model are that by relative magnet a of both positive and negative polarity and magnet b are set on support, magnet attracts each other during earthquake, thereby the detonator circuit closure makes the loudspeaker sounding of base lower end, reaches the purpose of warning, and is simple in structure, easy to operate, highly sensitive, low price.
Description of drawings
Fig. 1 is the structural representation of the utility model earthquake siren for household.
Among the figure, 1. insulating screw, 2. support, 3. spring, 4. can a, 5. magnet a, 6. can b, 7. magnet b, 8. battery, 9. loudspeaker, 10. electric wire.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The structure of the utility model earthquake siren for household, as shown in Figure 1, comprise support 2, the central mounting at support 2 tops has spring 3, spring 3 belows are hung with a magnet a5 who is wrapped in by can a4, and the below, bottom of support 2 is connected with loudspeaker 9, and top, the bottom of support 2 is connected with battery 8 simultaneously, the top of battery 8 is connected with a magnet b7 who is wrapped in by can b6, and loudspeaker 9 is connected with spring 3 by electric wire 10.
The course of work of the utility model earthquake siren for household:
Support 2 usefulness insulating screws 1 are fixed on the ceiling, the magnet a5 that is wrapped in by can a4 and be oppositely arranged by the magnet b7 both positive and negative polarity that can b6 is wrapped in, the length of regulating spring 3, magnet a5 and magnet b7 are not just attracted, when earthquake takes place, longitudinal wave propagation speed is fast, thereby causing the face of land pitches, spring 3 vertical tremors initiation magnet a5 and magnet b7 attract each other and make closing of circuit, thereby loudspeaker 9 sounding, reach the purpose of warning, allow people before shear wave arrives ground, just flee from rapidly.
The utility model earthquake siren for household, by relative magnet a of both positive and negative polarity and magnet b are set on support, magnet attracts each other during earthquake, thereby the detonator circuit closure makes the loudspeaker sounding of base lower end, reaches the purpose of warning, and is simple in structure, easy to operate, highly sensitive, low price.
