The electronic sensor for an earthquake alarm device is suitable for bulk production and is also is provided with a helping button which is convenient for rescue workers to search.

Description

The sensor of electronic earthquake warning device

The utility model relates to the vibrations warning device, particularly relates to detecting the sensor construction that rock on the face of land.

The earthquake alarming device of prior art, it detects the face of land and rocks the mechanical contact mode of generally all using, and uses the tinsel suspended pendulum as moving contact exactly, puts becket as stationary contact simultaneously around pendulum.In order to detect sensitivity, tinsel must guarantee enough pliabilitys, so that pendulum can freely swing, so all select thinner tinsel, the result is when transportation and installation, and the up and down suspension wire that usually causes of pendulum is damaged.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of simple in structure, with low cost, being fit to earthquake prone areas family uses, and the sensor, particularly a rolling dynamic sensor of the electronic earthquake warning device of aspect transportation and installation without suspension wire.

The purpose of this utility model can reach by taking following measure: making a kind of sensor of electronic earthquake warning device, is a kind of rolling dynamic sensor, comprises hook, metal tube, suspension rod and cylinder.Metal tube places in the ring-shaped protrusion of outer casing base, and plastic cap is placed in the plastic cap medium pore draw-in groove in the top of metal tube

The hook of shape, the upper end boring of suspension rod, hook penetrates wherein, and the Lower Half of suspension rod is through in the cylinder axial center hole, and locate up and down with nut at two ends.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the sensor of the utility model warning device---the structural representation of rolling dynamic sensor;

Fig. 2 is signal transmitting circuit and the sound generation device functional-block diagram that cooperates the working sensor of described warning device.

Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.The rolling dynamic sensor of the utility model warning device and signal transmitting circuit, sound generation device are assemblied in the shell jointly.The function of described warning device is in time to report to the police when earthquake takes place, and reminds people is selected from the explosive area, and earthquake especially takes place at night, and the sound equipment that warning device is ear-piercing wakes people so that in time make a response up from sleep.Described rolling dynamic sensor as shown in Figure 1, comprises hook 2, metal tube 3, suspension rod 4 and cylinder 6.Metal tube 3 places in the ring-shaped protrusion of outer casing base 8, has screw 14 to run through wherein on this jut, and directly being screwed on metal tube 3 tube walls has in the hole of female screw, with fixing metal pipe 3.The head of a nail of screw 14 down and crimping one plate electrode 13 is used to draw and rocks signal.Plastic cap 1 is placed on the top of metal tube 3.There is pin thread on this plastic cap Lower Half surface, in order to screw in metal tube 3 from top, cooperates with the female screw in it.Place in the plastic cap 1 medium pore draw-in groove

The hook 2 of shape, this hook is pressed into tinsel is curved, and its both wings are fixed on the end face of plastic cap 1 with screw 9 and 11, and the head of a nail of one piece of screw crimping one plate electrode 12 also down wherein is used to draw and rocks signal.

Fig. 1 middle hanger 4 is metal round rod, and both sides, upper end facing cut is flat, and in the plane central bore, hook 2 penetrates wherein, is suspended in the metal tube 3.The Lower Half surfacing cut of suspension rod 4 has pin thread, and there is axial through hole in cylinder 6 central authorities, and the Lower Half of suspension rod 4 penetrates wherein, and locate with

nut

5 and 7 at two ends.The top of suspension rod 4 is welded with ductile metal silk 10, and this tinsel other end is welded on the electrode 12.

Dress is with the warning device of the utility model sensor at ordinary times on the horizontal positioned floor, or fixing on the wall by the hook on its side wall of outer shell.Metal cylinder 6 is sagging naturally under the normal condition, does not contact with metal tube 3, and obstructed electric current between the electrode 12 and 13 is equivalent to the contact and disconnects.When earthquake took place, the face of land was rocked and is caused cylinder 6 to wave and metal tube 3 inwall intermittent contacts, and electrode 12 and 13 is communicated with frequently, closed when breaking when being equivalent to the contact, sent switching signal.

The dress warning device of the utility model sensor, its signal transmitting circuit and sound generation device all are prior aries, with 1.5 volts of dry cells, three joint series-feds.Fig. 2 is their functional-block diagram.Described warning device is ready under the normal condition.When earthquake took place, sensor was sent switching signal here, postponed a short time through the locking delay circuit, then gave sound control I signal, by its control audio oscillator and power-amplifier stage, made loudspeaker send rapid ear-piercing tweeting sound, and the report earthquake takes place.

The signal transmitting circuit of described warning device is provided with the emergency button.In the time of can't the flee danger district if people are stranded, can be at one's side described warning device band, flicking emergency button, the distress signal lock-in circuit promptly locks this switching signal, and give sound it and control II, reset with seasonal seismic signal locking delay circuit, sound control II starts sound generation device, and promptly audio frequency oscillator, power-amplifier stage and loudspeaker send an SOS.If the energy content of battery is about to exhaust, when testing circuit detects cell voltage and is lower than required value, promptly send low voltage signal and control II to sound, start sound generation device and send same distress signal.The effect of reset switch is, can be when not needing audible alarm with its closure, and seismic signal locking time-delay and distress signal lock-in circuit all are reset, and described warning device pursues does not do audible alarm.

With prior art relatively, the utility model has the advantage of: directly adopt hook to hang suspension rod and copper coin Post has been avoided hanging the transportation that causes and installing inconvenient with wire. The utility model compact conformation, body Long-pending little, each parts machining is simple, is fit to batch production. The circuit that cooperates the utility model working sensor Part is prior art, and reliable operation especially is provided with the emergency button, can make things convenient for the rescue personnel to search.
