CN201298278Y - Electronic seismoscope - Google Patents

Abstract

The utility model discloses an electronic seismoscope, which comprises a casing, a built-in circuit board in the casing, a shaking bar with a shaking rod, a buzzer, and an illumination lamp, wherein the bottom of the shaking bar is arranged and located in the shaking rod fixed base; an SR spherical spring in the fixed base is arranged at the lower part of the bottom of the shaking rod; a contact is arranged on the shaking bar and corresponds to a conductive sheet on a contact support; the illumination lamp is connected with the circuit board; and a wall mounting bracket is arranged on the casing. When the transverse wave from a seismic source is transmitted, the shaking bar can generate swing amplitude. The contact on the shaking rod can remain in contact with the conductive sheet when a certain degree of the amplitude is reached, meanwhile, the entire circuit is switched on to enable the buzzer and the illumination lamp to work, thereby reminding people to take measures as soon as possible for evacuation.

Description

The electronics seismograph

Technical field

The utility model relates to a kind of prior-warning device, is specially the seismograph that can respond to earthquake.

Background technology

At present, earthquake has brought very big disaster for the Sichuan people, and calamity also is accompanied by the irregular aftershock that often takes place later.Although big earthquake arriving early warning has national departments concerned to monitor, but people oneself have early warning to earthquake in order to allow in life at ordinary times, normally the beer bottle inversion is folded height on the table or with the mahjong piece, when if aftershock is come, break back or mahjong heap after beer bottle rocks and collapse, the people in will sleeping soundly wake up with a start and can take the measure of fleeing from.Such mode is more insensitive, even has some contingency, and the process that also is subjected to a lot of for example vehicles easily waits jolting of causing to wait some interference.

The utility model content

The purpose of this utility model is to provide a kind of electronics seismograph, and when ground was rocked to a certain degree, seismograph can be reported to the police, and reminds people takes measures to withdraw as early as possible.

For achieving the above object, be achieved by the following technical solution:

The electronics seismograph, comprise housing, housing is built-in with wiring board, have rock head rock bar, hummer, illuminating lamp, it is built-in spacing in rocking the bar holder to rock the bar bottom, have the spherical spring of SR to be arranged in the holder and rock bottom, bar bottom, rock and have the contact on the bar, the contact is corresponding with the conducting strip on the contact holder, illuminating lamp is connected with wiring board, and housing has the body of wall mounting bracket.

Described conducting strip has a V-type opening, and the contact of rocking on the bar can contact with conducting strip along with the shaking amplitude that rocks bar.

Described to rock head be a weight, thereby be to drive the swing rock bar in order to respond to rocking of ground better.

Seismic event has compressional wave and shear wave, and compressional wave can produce the vibration that pitches, and shear wave can produce rocking of horizontal direction, and shear wave is the main cause that causes building destruction.Adopt the electronics seismograph of said structure, when the shear wave conduction of earthquake focus is come, rock bar and can produce amplitude of fluctuation, when amplitude of fluctuation acquired a certain degree, the contact of rocking on the bar had touched conducting strip, at this moment, entire circuit is connected, buzzer warning, and illuminating lamp is bright.This product structure is simple, can be widely used in family.

Fig. 3 rocks structural representation in the bar holder for the utility model;

Fig. 4 is a circuit diagram of the present utility model.

Embodiment

As Fig. 1,2, shown in 3, the electronics seismograph, comprise housing 1, housing 1 is built-in with wiring board 2, have rock 3 rock bar 4, hummer 5, illuminating lamp 6, it is built-in spacing in rocking bar holder 7 to rock bar 4 bottoms, having the spherical spring 8 of SR to be arranged in the holder 7 rocks below bar 4 bottoms, rock and have contact 9 on the bar 4, contact 9 is corresponding with the conducting strip 11 on the contact holder 10, conducting strip 11 has a V-type opening 13, the contact 9 of rocking on the bar 4 can contact with conducting strip 11 along with the shaking amplitude that rocks bar 4, rocking 3 is a weight, thereby be to drive the swing of rocking bar 4 in order to respond to rocking of ground better, illuminating lamp 6 is connected with wiring board 2, and housing 1 has body of wall mounting bracket 12.When the shear wave conduction of earthquake focus is come, rock bar 4 and can produce amplitude of fluctuation, when amplitude of fluctuation acquired a certain degree, the contact 9 of rocking on the bar 4 had touched conducting strip 11, and at this moment, entire circuit is connected, buzzer warning, illuminating lamp is bright.

Claims (2)

1, electronics seismograph, comprise housing, it is characterized in that: housing is built-in with wiring board, have rock head rock bar, hummer, illuminating lamp, it is built-in spacing in rocking the bar holder to rock the bar bottom, have the spherical spring of SR to be arranged in the holder and rock bottom, bar bottom, rock and have the contact on the bar, the contact is corresponding with the conducting strip on the contact holder, illuminating lamp is connected with wiring board, and housing has the body of wall mounting bracket.

2, electronics seismograph as claimed in claim 1 is characterized in that: described conducting strip has a V-type opening, and the contact of rocking on the bar can contact with conducting strip along with the shaking amplitude that rocks bar.
