A kind of pendulum and spring ram public earthquake alarm for city and town
One, technical field
The present invention relates to a kind of pendulum and spring ram public earthquake alarm for city and town, it adds rocking of spring tup with plug in stock under many groups pendulum and the collision of fixed contact generation on every side is the warning benchmark, belongs to the imminent earthquake alarm technique that rocks the trigger circuit closo.Form because of this alarm is mixed by many groups of multiple pendulums, can tackle the imminent earthquake ripple from different azimuth and different-waveband, particularly its number of times that can rock along with the face of land and giving the alarm does not promptly need to add adjusting again and can implement auto-alarm-signal keying device continuously.Use with the independent public earthquake automatic alarm as a county town or small towns and village of activation, the earthquake automatic alarm net that also can form an area uses.
Two, background technology
The time by now, though it is more also very advanced to be used for the instrument kind of prediction about imminent earthquakes and monitoring, but because people are to the origin cause of formation of earthquake with select monitoring place etc. to lack knowledge and skills, difficulty can be made accurate forecast before violent earthquake was arrived, everybody can only lean on the good fortune of destiny temporarily when violent earthquake comes, violent earthquake 80,000 people in Wenchuan are wrecked to be exactly a miserable example, and consequently, people urgently wish to have a kind of public alarm facility.
Three, summary of the invention
Rocking ripple because of the destructiveness of earthquake also is to be come by little increase, and to rock each time of ripple also inequality on the face of land of imminent earthquake, even the earthquake that has even shake the preceding face of land and can occur rocking several times, so, the present invention seeks to design a kind of pendulum and spring ram public earthquake alarm for city and town, the number of times that it can rock along with the face of land and giving the alarm does not promptly need to be regulated again and can implement auto-alarm-signal keying device continuously.This alarm can independently use as the public automatic imminent earthquake warning system in a county town and small towns and village, and the earthquake automatic alarm net that also can form an area uses.And can be used as automatically the transmitter of cities and towns spreading and propagation imminent earthquake alerting signal towards periphery again.And this alarm can also send single the kind and multiple imminent earthquake alarm, makes the common people in earthquake region can get the face of land and rocks alarm, common evacuation alarm, emergency evacuation alarm etc.Also can solve people preferably and begin in advance before the earthquake to evacuate directly not feeling, evacuate in advance simultaneously and mean that also egress door is not opened by distortion easily yet, it is minimum to make earthquake cause injures and deaths to reduce to.
For achieving the above object, the solution that the present invention takes is: a kind of pendulum and spring ram public earthquake alarm for city and town, it is mainly mixed by many groups of multiple pendulums and forms, and produce collision with rocking of stock and spring tup with fixed contact on every side and be the warning benchmark of each group, genus rocks the imminent earthquake alarm technique of trigger circuit closo.Warning circuit is for disconnecting when awaiting orders, and during enforcement, reports to the police and cities and towns transmitting signal towards periphery thereby warning circuit produces closed sending.
Feature and advantage of the present invention are that this alarm can send single the kind or simultaneously multiple imminent earthquake alarm, and people can be evacuated and the multiple different information of emergency evacuation usually.It is simple in structure, and all functions all belong to general physics, long service life.And pendulum stock and spring tup rock warning reference range scalable, rock misleading or the false declaration that is produced a little less than eliminating.When the pendulum of this alarm can not give the alarm when static, promptly in this state, can never produce buildings and cave in without foundation.When if pendulum begins to rock alarm and gives the alarm, be exactly that the face of land is in rocking, also before the earthquake million.Particularly working as earthquake in the late into the night comes interim, the people that the alarm sound of this alarm can not only wake up in the sleep hasten to flee from, and evacuation in advance means that also lighting lamp is also for normal, avoid crowded mutually from pitch-dark flurried evacuation, not opened easily by distortion with egress door road early, it is minimum to make earthquake cause injures and deaths to reduce to.

Five, embodiment
With reference to the accompanying drawings the present invention is remake description below.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of pendulum and spring ram public earthquake alarm for city and town, comprise an alarm cabinet chassis (1), below, chassis (1) is established a cabinet lower bottom base (2) is installed, an alarm cabinet shell (3) is established in top, chassis (1), a plurality of contactors (4) and many miniature relays (5) are installed on two walls about cabinet shell (3), set up a warning piece device frame (6) at the cabinet central part, settle an A group imminent earthquake blue light (7) on device frame (6) panel, a B group imminent earthquake blue light (8), a C group imminent earthquake blue light (9) and a D group imminent earthquake blue light (10).Establish a plurality of pendulum point cutting edge of a knife or a sword axle pedestals (11) in warning piece device frame (6) panel upper end, each pedestal (11) is fixing with four screws (12), stretch out pendulum point cutting edge of a knife or a sword axle (13) from each pendulum point cutting edge of a knife or a sword axle pedestal (11) middle part, each pendulum point cutting edge of a knife or a sword axle (13) pendulum point cutting edge of a knife or a sword axle sleeve (15) that matches, the anti-sway toe cutting edge of a knife or a sword axle sleeve banking pin (14) that portals is established in axle sleeve (15) top, and pendulum point cutting edge of a knife or a sword axle sleeve (15) can not be shifted out outside the pivot cutting edge of a knife or a sword.Each sharp cutting edge of a knife or a sword axle sleeve (15) below connects pendulum connecting rod (16), connecting rod (16) the lower end pendulum (17) that joins, and when the imminent earthquake face of land began slightly to rock, pendulum (17) produced the inertia interaction energy of returning and increases intensity and the amplitude of rocking.Plug in a stock (18) in pendulum (17) below, the lower end of stock under the pendulum (18) is overlapped one again and is increased and rock soft spring (19), a tup (20) is established in the soft spring lower end, owing to obtain stock under the pendulum (18) and increase the lengthening that rocks soft spring (19), make the shaking amplitude of spring lower end tup (20) bigger.Around the tup of spring lower end, be provided with a plurality of fixed contacts (21), each fixed contact (21) rear all is provided with an adjusting fixed contact seat (22) and contact range screw (23) is rocked in one piece of adjusting, rock contact range screw (23) by fixed contact seat (22) and adjusting and can in time proofread and correct and to rock the gap, guarantee the sensitivity of alarm.And be provided with an insulcrete in fixed contact (21) below, make the warning circuit of the attitude of awaiting orders can not be unobstructed.Each pendulum group all is provided with an energising number of times register (25) on warning piece device frame (6) panel, is the highest earthquake magnitude of minute book secondary earthquake.On warning piece device frame (6) panel, also establish six electroclocks (26), can write down the time of at every turn sending warning.Be provided with at four angles that cabinet is installed lower bottom base and land mounting screw (27).Before and after cabinet, respectively be provided with a pair of cabinet door (28), the handle that opens the door (29) all is housed on the cabinet door.
This alarm is respectively equipped with 8 pendulum groups, increasing of A pendulum group leader bar (18) lower end institute socket rocked soft spring (19) for the longest, increasing of D pendulum group leader bar (18) lower end institute socket rocked soft spring (19) for the shortest, and increasing of B, C, the socket of pendulum group leader bar (18) lower end institute rocked soft spring (19) between two parties.E pendulum group does not have the spring tup, and tup is for the most following.F pendulum group does not have the spring tup, and tup be on, G pendulum group does not have the spring tup, and tup be in down, H pendulum group does not have the spring tup, and tup is for going up most.The tup of each pendulum group has height like this, can send different warnings in rock on the face of land of different earthquake magnitudes and different seismic waves.A, B, C, D pendulum group are in the place ahead of cabinet, and E, F, G, H pendulum group are in the rear of cabinet.In a word, this alarm demonstrates separately function and effect by the height that increases the length of rocking soft spring (19) and pendulum.
Referring to Fig. 4, Fig. 5, this alarm mainly is provided with a circumscripted power line (30), and each pendulum group all has identical circuit, establishes one and leads to the power lead (31) of respectively organizing pendulum.Each pendulum group is all established an electric wire (32) that transfers to energising number of times register and electroclock switch, and output line (33) is connected in a fixed contact collision, and one transfers to public alert speaker line (34) and is connected imminent earthquake alarm signal lamp line (35) with one.Each bar transfers to public alert speaker line (34) and all is pooled to public alert speaker (36).Be provided with 2 miniature relays in circumscripted power line (30) lower end and be respectively AC power and direct supply (A1) (A2).Article 8, fixed contact collision connect output line (33) establish 8 miniature relays (C1) (C2) (C3) (C4) (C5) (C6) (C7) (C8) be connection terminal, each miniature relay all connects a public warning light.All establish during each miniature relay is closed circuit a time relay (B1) (B2) (B3) (B4) (B5) (B6) (B7) (B8), if make like this give the alarm at every turn the back face of land stop to rock, alarm also can stop alarm automatically when the time comes.When treating that the next face of land occurs rocking again, alarm can give the alarm again automatically.Alarm can be kept repeatedly and give the alarm automatically thus.
If this alarm has been installed in a certain county town or small towns and village, when the earthquake arriving face of land begins slightly to rock, the alarm cabinet chassis (1) and the warning piece device frame (6) that are fixed on the face of land are also followed the generation slight wobble, and this slightly rocks by passing to pendulum (17) under the pendulum connecting rod (16).Pendulum (17) is also produced rock, and under the effect of returning of the inertia of pendulum (17), increased intensity and the amplitude of rocking.Cause the stock (18) or the spring top tup (20) of pendulum lower end in rocking greatly, to connect circuit for alarming with fixed contact (21) generation collision on every side, electric current is transported to miniature relay (C1) back and produces closed, the output alarm signal is disseminated to alarm speaker (36), thereby sends the imminent earthquake alarm.Owing to all have one the tunnel to connect energising number of times register (25) and electroclock (26) in every group of alarm signal output line, make behind the every grade of signal that gives the alarm at energising number of times register (25) and increased a numeral and electroclock (25) has write down the time, consequently, learn the alarm number of times of this secondary earthquake, also know the time of each alarm simultaneously.
Because of mixing institute by 8 kinds of multi-form pendulum groups, this alarm forms, can rock ripple by the various imminent earthquakes of reply, next interim when the earthquake of a certain cities and towns, it can send the imminent earthquake alarm in the very first time, make people obtain evacuation alarm the earliest, so that reach and alleviate the number of casualties that earthquake causes.This warning system is a console mode, general cabinet height is about 1.5--3 rice, if pendulum (17) has when slightly rocking, the stock (18) of pendulum (17) below and its shaking amplitude of spring top tup (20) are than big several times of pendulum (17), and this connecting circuit mode belongs to directly and do not amplify through more original paper again, reaches accurately simple again.When the pendulum (17) of alarm can not give the alarm when static, promptly can never produce buildings and cave in without foundation.When if pendulum (17) begins to rock alarm and gives the alarm, be exactly that the face of land is in rocking, also before the earthquake million.From the development progress of the forecast and the monitoring of current earthquake, it is impossible making accurate forecast before earthquake is arrived, even understand the origin cause of formation of earthquake from now on fully, also difficulty can forecast that earthquake can take place somewhere some time one day.Have this public autoalarm only and be the most desirable earthquake counter measure that can realize again.
