Abstract
The utility model relates to an earthquake alarm device for domestic use, which belongs to a household earthquake alarm device, aiming to provide a civil earthquake alarm device with the combination of low cost and family decoration. The utility model is that a structure of an alarm circuit with connection in series is composed of an earthquake sensing ball which falls down by the vibration of an earthquake, a casing 5 which is used for bearing the earthquake sensing ball, an earthquake sensing switch K which is composed of two contacts 2, 3, an alarm electric bell R which is triggered by the earthquake sensing switch and a power supply. The utility model has the advantages of simple structure and practicality.
Description
The utility model belongs to the household earthquake warning device.
At present, earthquake alarm relies on the professional to Government Report, again in press to the disclosed Forecast Mode of the public.Usually, little earthquake magnitude is not reported, adds society and occurs rumour sometimes, causes the unnecessary fear of people easily.If an earthquake alarming device that cost is low, practical is installed within the family, other can increase the sense of security common people.
The utility model purpose is to propose a kind of civilian, and low cost is in conjunction with the earthquake alarming device of home decoration.
The utility model purpose is achieved in that
A kind of earthquake siren for household, it is characterized in that to earthquake seismaesthesia sensitivity by seismaesthesia ball 1, cylindrical case 5, the seismaesthesia K switch that seismaesthesia resilience contact 3 and fixed contact 2 formed; And the warning circuit structure that is in series of the warning electric bell R that triggers by the seismaesthesia K switch and power supply E; Described seismaesthesia ball is by cylindrical case 5 upper end hydraucone supports, and pressing seismaesthesia resilience contact 3, keeps seismaesthesia K switch off state, and seismaesthesia ball 1 is shaken by earthquake, and then 2 contacts (2,3) are connected, and electric bell is reported to the police.
In conjunction with the accompanying drawings, further specify the utility model content.
Fig. 1. the utility model circuit theory diagrams and seismaesthesia switch junctions composition
Fig. 2. the utility model seismaesthesia schematic diagram
Fig. 3. the utility model is implemented illustration
Identifier is as follows among the figure:
1 seismaesthesia ball, 2 switch fixed contacts, 3 seismaesthesia resilience contacts, 4 switch wires
The high R electric bell of 5 seismaesthesia switch housing h billiard tables K seismaesthesia switch
The E battery
Fig. 1 the utility model circuit theory diagrams and seismaesthesia switch junctions composition. Left figure is seismaesthesia K switch structure chart, and right figure is electricity The road schematic diagram. This seismaesthesia K switch is by seismaesthesia ball 1, switch fixed contact 2, seismaesthesia resilience contact 3, switch wire 4, seismaesthesia Switch housing 5 forms; And control circuit is by electric bell R, the seismaesthesia K switch, and battery E is in series. The former is outside the tubular seismaesthesia Shell 5 upper ends are horn-like, and support seismaesthesia ball 1, and the seismaesthesia ball is being pressed seismaesthesia resilience contact 3, make it admittedly not put the contact with switch 2 contacts, and keep off state; Latter's control circuit is contained in the cylindrical case 5, and electric bell outside.
When the Earthquake propagated sensation came, cylindrical case 5 upper end loudspeaker rests were fallen by shake at seismaesthesia ball 1, seismaesthesia resilience contact 3 bullets Return, and be communicated with switch fixed contact 2. So circuit is started working, electric bell R reports to the police.
Fig. 2 is the utility model seismaesthesia schematic diagram. The high hn of billiard table＜... h2＜h
1=r, 5 pairs of shakes of shell are depended in seismaesthesia sensitivity The support relation of sense ball 1, this support relation is corresponding to the support face size of 5 pairs of seismaesthesia balls 1 of shell. The support face is by on the shell The end horn mouth determines the billiard table that comprises formation of seismaesthesia ball. When the high hn of billiard table is changed to zero by sphere diameter r, then seismaesthesia spirit Sensitivity changes from low to high, and it corresponds respectively to earthquake magnitude from high to low.
Above described seismaesthesia ball 1 can be steel ball, also glass marble etc., according to own needs, the user can build dress in doors The alarm of several different earthquake magnitude sensitivity series is installed on the jewelry.
Fig. 3 is that the utility model is implemented illustration.A huge decoration painting is equipped with the alarm of 5 different earthquake magnitude sensitivity behind.
The utility model advantage:
Simple in structure, practicality is convenient to attaching on the building decoration thing.
Embodiment:
Fig. 3 is a huge decoration painting, and the alarm of 5 earthquake magnitude sensitivity is housed behind.The glass seismaesthesia ball horizontally-arranged of flash of light is at decorative cover top, i.e. K
1... K
53 volts of batteries are put in the cylindrical case 5, and electric bell is commercially available doorbell, and are hidden in the back side of picture.Through using, the simulation seismaesthesia can sensitively be reported to the police.
