Abstract
The utility model relates to a domestic emergency earthquake alarm device, which is composed of a box body, a direct current (dc) power supply, a sound integrated circuit buzzer, a horizontal vibration sensor, and a vertical vibration sensor. Touch seats of two sensors are electrically connected with the negative electrodes of the power source, contact terminals of the two sensors are electrically connected with the positive electrodes of the power source by the sound integrated circuit and the buzzer. Compared with prior art, the utility model has the advantages of testing omni-direction vibration with sensitivity, sound and optics alarm at the same time; the alarm device can be used for alarm of a near term earthquake.
Description
The utility model relates to a kind of household seismic warning device.
Existing home-use earthquake alarming device sends alerting signal to people when mostly being used for the earthquake generation, and the prompting people hide injury.For example Chinese patent CN2055959U disclosed " sound equipment earthquake Alarm " is exactly wherein a kind of.Vibration transducer that this alarm is made of joint, touch base, messenger wire, lead and electronics news are rung circuit and are constituted, and have simple in structurely, with low cost, are suitable for the characteristics of family.When earthquake took place, along with the vibration of the earth, alarm sound can take place in this alarm.But the structures shape of this alarm it only to the vibration sensing of horizontal direction, and insensitive to the vibration of vertical direction, therefore when the vibration of seismic event generation is vertical direction, this alarm might detect less than.
The purpose of this utility model is to provide a kind of family earthquake alarming device of meeting an urgent need, the vibration that this device can not only the Sensitive Detection horizontal direction, and can detect the vibration of vertical direction delicately.
For achieving the above object, the utility model adopts following technical scheme: it mainly comprises a box body, direct supply, audio ic, news Chinese percussion instrument, horizontal vibration sensor and vertical vibrating sensor, the horizontal vibration sensor is by main pendulum, and suspension bracket, secondary pendulum, contact, touch base constitute.Vertically vibration sensor is by weight, and main reed, auxiliary spring sheet, contact, touch base constitute.Touch base in the two sensors is electrically connected with power cathode, and the contact of two sensors is electrically connected with positive source through audio ic Homeway.com Chinese percussion instrument.When earthquake takes place, the vibration of horizontal vibration sensor horizontal direction, the vibration of vertical vibrating sensor vertical direction, because the swing displacement of main pendulum or weight makes corresponding contact, touch base is connected circuit, the news Chinese percussion instrument sends alarm sound.
For making the utility model can send sound equipment, can send light again, can also be at news Chinese percussion instrument end warning light in parallel.
Because the utility model is provided with horizontal vibration sensor and vertical vibrating sensor, compared with the prior art, has the advantage that comprehensive vibration of Sensitive Detection and acousto-optic are reported to the police simultaneously.
Further describe embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 the utility model horizontal vibration sensor
Fig. 2 the utility model vertical vibrating sensor
Fig. 3 the utility model electrical schematic diagram
Fig. 4 suspension bracket synoptic diagram (Figure 1A is to view)
The utility model (referring to accompanying drawing) mainly comprises direct supply 18, switch 19, and vertical vibrating sensor 21, horizontal vibration sensor 20, warning light 15, audio ic 16 Homeway.com Chinese percussion instruments 17, this news Chinese percussion instrument are a Microspeaker.Above-mentioned whole element assembles, and is contained in the box body 13, and the horizontal vibration sensor is made of main pendulum 1, secondary pendulum 2, suspension bracket 7, contact 4, touch base 3.Main pendulum is hung on metal suspension bracket by metal fork 6, and suspension bracket is fixed on the box body roof, and has lead 14 to be electrically connected with suspension bracket.Contact is fixed on the metal fork, secondary pendulum is hung by fine wire and is fixed on the box body roof, also be electrically connected with it by lead 14, be provided with touch base below the secondary pendulum, touch base is a loop configuration, be sleeved on the contact, and maintain certain interval, this gap is after installing setting, do not change with the utility model placement location, even it is placed on comparatively on the plane inclined, main pendulum and secondary pendulum also will keep same vertical state, above-mentioned gap is remained unchanged, and can not influence the sensitivity of this sensor.The weight 12 of vertical vibrating sensor is fixed on the sidewall of box body by main reed 11, main reed is provided with contact 10, the corresponding with it touch base 9 that is provided with is fixed on the box side wall by auxiliary spring sheet 8, and main reed and auxiliary spring sheet are sheet metal and are provided with thereon draws lead 14.The touch base of the touch base of horizontal vibration sensor and vertical sensor is electrically connected with power cathode through lead.The contact of two sensors is connected to positive source by lead and audio ic, Microspeaker after contacting.Close a switch 19, the utility model just can be devoted oneself to work.For guaranteeing that the utility model is long-term effectively sensitive, contact and touch base are all done silver-plated processing.
Claims (2)
1, a kind of family earthquake alarming device of meeting an urgent need, box body is arranged, direct supply, the electronics news are rung circuit, vibration transducer, it is characterized in that, it is audio ic Homeway.com Chinese percussion instrument that described electronics news are rung circuit, described vibration transducer is by main pendulum, suspension bracket, secondary pendulum, contact, the horizontal vibration sensor that touch base constitutes and by weight, main reed, the auxiliary spring sheet, contact, the vertical vibrating sensor that touch base constitutes, touch base in the two sensors is electrically connected with described dc power cathode, and the contact in the two sensors is electrically connected with dc power anode through audio ic Homeway.com Chinese percussion instrument.
