Abstract

The utility model relates an early warning device, in particular to an earthquake reminding instrument. Aiming at the problems, the utility model provides an earthquake reminding instrument which is simple in structure, convenient to use, and high in sensitivity, and can detect the longitudinal wave to early warn. The earthquake reminding instrument has the following main principle that: when an earthquake occurs, the earthquake wave transmits immediately, and the lengthways shaking caused by the lengthways wave and the transverse shaking caused by the transverse wave are necessarily and mutually contacted with a horizontal guide wire (12) due to the T-shaped line structure of a vertical guide wire (11), so that a circuit is switched on, and an alarm lamp (15) and a loudspeaker (16) start to alarm. The earthquake reminding instrument has the benefit effects of being simple in structure and convenient to use, being high in sensitivity to be capable of detecting the previously-reached lengthways wave so as to lead persons to have enough time to evacuate before the transverse wave with great destructive power reaches, and being capable of alarming even under the condition of the interruption of power supply due to the charging and discharging device.

Description

The earthquake prompting instrument

Technical field

The utility model relates to a kind of prior-warning device, is specially a kind of earthquake prompting instrument.

Background technology

Be that the earth interior medium is local rapid breaking take place in earthquake, the seismic wave of generation, thus cause the phenomenon of ground vibration within the specific limits.Earthquake usually causes serious casualties and destroys job facilities such as house, especially in public places with densely populated place, causes serious loss easilier.Therefore earthquake is reminded and is just seemed particularly important, but the seismic monitoring instrument of current earthquake prediction department is complex structure all, the cost costliness, be not suitable in public places, the local use such as family, just make the early warning of earthquake lag behind than the earthquake that takes place rapidly, make people when earthquake takes place, can not get in time, remind accurately, thereby wasted the gold 12 seconds when earthquake takes place.In the middle of the present disclosed patent document, as the patent No. is that 95218630.6 the pendulum tilting household earthquake instrument by name and the patent No. are described in 200810080028.5 the earthquake siren for household by name, all be that seismograph is placed on the horizontal, occupation of land side very, inconvenient, and wherein vertical wires is connected through swing and horizontal wire, start alarm, but when earthquake takes place, compressional wave and shear wave are arranged in the seismic event, and compressional wave at first arrives, and it makes that ground is vertical tremor, and this is, act on less than a bit by waving the device of reporting to the police in the middle of the public technology, being only of arriving afterwards makes about ground, the shear wave that rocks back and forth, this also is the main cause that causes harm such as buildingss, at this moment withdraws and has lost the best opportunity.

Summary of the invention

The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, easy to use, highly sensitive, can detect the earthquake prompting instrument that therefore compressional wave more early gives the alarm.

The utility model earthquake prompting instrument is made up of fixed support (1), lower bottom base (2), upper bed-plate (3), screw rod (4), nut (5), balancing spring (6), balance knob (7), screw (8), shell (9), balance bob (10), vertical wires (11), horizontal wire (12), vibrating spring (13), power supply indication (14), alarm lamp (15), loudspeaker (16), storage battery and charger (17), plug (18); It is characterized in that: lower bottom base (2) two bottom sides is separately fixed on two fixed supports (1), and fixed support (1) is " 7 " font, and two screws are respectively arranged on vertical plate; Four screw rods (4) bottoms is separately fixed at the centre on each limit of lower bottom base (2), and passes upper bed-plate (3) and be connected with it, is fixed by nut (5) at last; Balancing spring (6) is placed in place, (2) four angles of lower bottom base, and supports upper bed-plate (3), and the upper bed-plate corresponding position is provided with balance knob (7), and balance knob (7) passes the length that upper bed-plate (3) is controlled corresponding balancing spring (6); Shell (9) is fixed on upper bed-plate (3) middle part by the screw (8) on four angles respectively; Shell (9) top is provided with loudspeaker (16), front upper is respectively equipped with power supply indication (14) and alarm lamp (15), vertical wires (11) and centre that inside is provided with band balance bob (10) are the horizontal wire of copper ring (12), vertical wires (11) top is parallel with vibrating spring (13), pass the copper ring of middle part in the middle of horizontal wire (12), vertical wires (11) is passed the copper conductor of the part of copper ring for no skin, and on this no skin copper conductor, the position slightly higher than copper ring is provided with a length does not again have the skin copper conductor greater than the level of copper ring radius; Plug (18) connects storage battery and charger (17) is positioned at lower bottom base bottom (2).

The utility model earthquake prompting instrument cardinal principle is, when earthquake produces, seismic event transmits immediately, no matter be the shake up and down that compressional wave causes, still the rocking all around that cause of shear wave is because the capable structure of horizontal " fourth " word of vertical wires (11) will inevitably be in contact with one another with horizontal wire (12), circuit is connected, the warning of starting working of alarm lamp (15) and loudspeaker (16); Its beneficial effect is: simple in structure, easy to use; Highly sensitive, can detect the compressional wave of previous arrival, before the huge shear wave of destructive power arrives, allow people again time enough withdraw; Self has charge and discharge device, even also can give the alarm under the situation of outage.

Embodiment

Example 1

The utility model earthquake prompting instrument when mounted, as Fig. 1, shown in Figure 2, earlier the fixed support (1) that supports lower bottom base (2) is installed on the metope, again upper bed-plate (3) is installed on four screw rods (4) and four balancing springs (6) on the lower bottom base (2), fix nut (5), fix storage battery and charger (17), (18) plug in, energized, at this moment loudspeaker (16) sounds, and alarm lamp (15) also can glimmer, adjustment knob (7), extinguish until alarm lamp (15), loudspeaker (16) stops, and the earthquake prompting instrument promptly is adjusted to optimum condition, the debugging installation.The earthquake prompting instrument should be installed in apart from two meters high on ground and be difficult for allowing on the body of wall that other people touch, and slotting good plug guarantees the long-term sufficient power of power supply, at any time be in holding state, when earthquake takes place when, earthquake prompting instrument loudspeaker (15) will send loud alarm song, alarm lamp (15) is bright simultaneously, and the reminds people earthquake has taken place.When slight earthquake or earthquake prompting instrument are far apart from the earthquake centre, the sound that earthquake prompting instrument loudspeaker (15) sends is less and very very brief, when larger earthquake or earthquake prompting instrument taking place when nearer apart from the earthquake centre, the loudspeaker of earthquake prompting instrument (15) then can send very big continuous alarm song.

Example 2

The utility model earthquake prompting instrument in use, circuit operation and control are as shown in Figure 3, Figure 4, the relation of vertical wires (11) and horizontal wire (12) is as switch, when earthquake takes place, vertical wires (11) vertical tremor or all around rock, no skin copper conductor all can touch the copper ring of horizontal wire (12), both switch closure, the warning of starting working of circuit communication then, alarm lamp (15) and loudspeaker (16); Alarm lamp (15) and loudspeaker (16) stability that improves circuit in parallel; Power supply indication (14) is a diode, and (18) power connection that plugs in then lights voluntarily; Two resistance of the setting in the circuit guarantee the safety of electronic component and stablizing of circuit respectively.
