Abstract
The utility model discloses a domestic earthquake alarm device, which comprises a power supply, an insulated cylindrical casing, a conductive ball, a cone-shaped conductive supporting platform, a conductive ring and an alarm sounder. The conductive ring is arranged on the circumference of the inner wall of the cylindrical casing, the cone-shaped conductive supporting platform is fixedly arranged in the cylindrical casing and located in the middle of the conductive ring, the conductive ball is arranged at the top of the cone-shaped conductive supporting platform, the distance between the bottom edge of the cone-shaped conductive supporting platform and the inner edge of the conductive ring is less than the diameter of the conductive ball, a positive pole of the power supply is connected with a positive pole of the alarm sounder, the conductive ring is connected with a negative pole of the power supply, and the cone-shaped conductive supporting platform is connected with a negative pole of the alarm sounder. During earthquakes, the conductive ball rolls down, the conductive ring and the cone-shaped conductive supporting platform are communicated through the conductive ball so as to enable the alarm sounder and the positive electrode and the negative electrode of the power supply to be communicated to form a return circuit, and the alarm sounder raises alarm to remind users to take refuge in time. The domestic earthquake alarm device is simple in structure, small in size, low in cost, convenient to use and particularly suitable for household use.
Description
Technical field
The instrument of warning usefulness related in particular to a kind of household earthquake warning device when the utility model related to a kind of earthquake.
Background technology
At present, the instrument kind that is used for the household earthquake warning device is more and more, but belongs to special-purpose, large-scale, accurate, expensive warning instrument mostly, only adapts to earthquake speciality office and uses.Though earthquake can't be accomplished accurate forecast, can early warning.If can when earthquake be about to take place or just begun to take place, just capture seismic signal and in time send earthquake pre-warning; Just can reminds people in time take refuge; Thereby avoid or reduce casualty loss; Often pre-shock many times can take place in a special violent earthquake usually before outburst, just seemed particularly important if can capture these pre-shock signals.Household earthquake warning device complex structure of the prior art, cost an arm and a leg, incompatibility family uses.
The utility model content
To above-mentioned weak point, the utility model provides a kind of small-sized, household earthquake warning device cheaply that adapts to that family uses, and this household earthquake warning device is simple in structure, easy to use.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme: the household earthquake warning device comprises the circular cylindrical shell, conducting sphere of power supply, insulation, conical conduction saddle, conducting ring and warning acoustical generator; Said conducting ring is located on the inwall circumference of circular cylindrical shell; Said conical conduction saddle fixedly is located in the circular cylindrical shell and is positioned at the middle part of conducting ring; Conducting sphere is shelved on the top of conical conduction saddle, and the distance between the bottom margin of conical conduction saddle and the inward flange of conducting ring is less than the diameter of conducting sphere; The positive pole of said power supply is connected with the positive pole of warning acoustical generator, and conducting ring is connected with the negative pole of power supply, and said conical conduction saddle is connected with the negative pole of warning acoustical generator.
As a kind of preferred version of the utility model, said conical conduction saddle is fixed on the bracing frame, and the bottom of support frame as described above is fixed on the bottom of circular cylindrical shell.
As the another kind of preferred version of the utility model, the top drilling of said circular cylindrical shell, the warning acoustical generator is embedded in the top-portion apertures of circular cylindrical shell.
As another preferred version of the utility model, the top of said circular cylindrical shell is provided with carrying handle.
The beneficial effect of the utility model is: the utility model is employed on the conical conduction saddle and shelves conducting sphere; During earthquake; Conducting sphere tumbles, and conducting ring is communicated with through conducting sphere with conical conduction saddle, the warning acoustical generator is communicated with the both positive and negative polarity of power supply forms the loop; The warning acoustical generator gives the alarm, and reminds people is in time taken refuge; This household earthquake warning device is simple in structure, volume is little, cost is low, easy to use, adapt to family especially and use.
Description of drawings
Fig. 1 is the structural representation of household earthquake warning device.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done to describe in further detail.
As shown in Figure 1, the household earthquake warning device comprises circular cylindrical shell 1, conducting sphere 2, conical conduction saddle 3, conducting ring 4, warning acoustical generator 5 and the bracing frame 6 of power supply, insulation.Conducting ring 4 is arranged on the inwall circumference of circular cylindrical shell 1; The bottom of bracing frame 6 is fixed on the bottom centre position of circular cylindrical shell 1; Upwards stretch out from the endoporus of conducting ring 4 at the top, and conical conduction saddle 3 is fixed on the top of bracing frame 6, and conical conduction saddle 3 is positioned at the middle part of conducting ring 4; Conducting sphere 2 is shelved on the top of conical conduction saddle 3, and the distance between the bottom margin of conical conduction saddle 3 and the inward flange of conducting ring 4 is less than the diameter of conducting sphere 2.The positive pole of power supply is connected with the positive pole of warning acoustical generator 5, and conducting ring 4 is connected with the negative pole of power supply, and conical conduction saddle 3 is connected with the negative pole of warning acoustical generator 5.When earthquake takes place when; Conducting sphere 2 tumbles from taper shape conduction saddle 3; Conducting sphere 2 contacts with conducting ring 4 with conical conduction saddle 3, and conical conduction saddle 3 and conducting ring 4 make warning acoustical generator 4 be communicated with the positive and negative polarities of power supply and give the alarm through conducting sphere 2 conductings.
The top drilling of circular cylindrical shell 1, warning acoustical generator 5 is embedded in the top-portion apertures of circular cylindrical shell 1.The top of circular cylindrical shell 1 is provided with carrying handle 7, can move the household earthquake warning device at any time through carrying handle 7, and it is very convenient to use, and battery main switch can be located at outside the circular cylindrical shell 1, is convenient to control the power supply in the circular cylindrical shell 1.Circular cylindrical shell 1 adopts transparent material to process, and whether the observer can be shelved on the conical conduction saddle 3 by comprehensive observation conducting sphere 2.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
