Abstract
The utility model discloses an earthquake early warning device comprising a box; wherein a steel ring is suspended at a top inside the box through a copper wire; a periphery of an inner part of the box, which is close to the steel ring, is provided with a metal induction device; an alarm circuit is arranged below the metal induction device; the steel ring, the copper wire, the metal induction device and the alarm circuit are connected in order through leads; the alarm circuit consists of a power supply, a delay trigger, and an alarm; and the delay trigger is respectively connected with the copper wire and the metal induction device through leads, the power supply is respectively connected with the metal induction device and the copper wire through leads, the alarm is connected with the delay trigger through a lead. The earthquake early warning device of the utility model has a simple structure, and can emit an early warning in the first time, therefore, the earthquake early warning device of the utility model is a small-sized earthquake early warning device especially suitable for a family.
Description
Technical field
The utility model belongs to disaster alarm device technique field, relates to a kind of earthquake pre-warning device.
Background technology
At present; The earthquake pre-warning device of using on the market costs an arm and a leg mostly, complicated operation, and it is uncommon to be used for the small-sized earthquake pre-warning device of family, especially when night, people slept soundly, is neglectful in taking precautions; Can not hide timely and shift, thereby cause huge property loss and casualties.
Summary of the invention
The purpose of the utility model provides a kind of earthquake pre-warning device, has solved the problem of the small-sized earthquake pre-warning device complicated operation that is used for family in the prior art.
The technical scheme that the utility model adopted is; A kind of earthquake pre-warning device; Comprise box body, the top in the box body is through the copper cash steel loop that suspended, and is provided with the metal inductive device in the inside of box body around near steel loop; Below the metal inductive device, be provided with warning circuit, steel loop, copper cash, metal inductive device are connected through lead with warning circuit successively; Warning circuit is by power supply, and time-delay trigger and alarm are formed, and time-delay trigger is connected with the metal inductive device with copper cash respectively through lead, and power supply is connected with copper cash with the metal inductive device respectively through lead, and alarm is connected with time-delay trigger through lead.
The beneficial effect of the utility model is, and is simple in structure, can send earthquake pre-warning in the very first time, is specially adapted to the small-sized earthquake alarming device of family.
Description of drawings
Fig. 1 is the structural representation of the utility model earthquake pre-warning device;
Fig. 2 is the utility model earthquake pre-warning manipulated or operated apparatus.
Among the figure, 1. box body, 2. copper cash, 3. steel loop, 4. power supply, 5. metal inductive device, 6. warning circuit, 7. time-delay trigger, 8. alarm.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
The structure of a kind of earthquake pre-warning device of the utility model; As shown in Figure 1; Comprise box body 1, the top in the box body 1 is through copper cash 2 steel loop 3 that suspended, and is provided with metal inductive device 5 in the inside of box body 1 around near steel loop 3; Below metal inductive device 5, be provided with warning circuit 6, said steel loop 3, copper cash 2, metal inductive device 5 are connected through lead with warning circuit 6 successively; Warning circuit 6 is by power supply 4; Time-delay trigger 7 is formed with alarm 8; Time-delay trigger 7 is connected with metal inductive device 5 with copper cash 2 respectively through lead, and power supply 4 is connected with copper cash 2 with metal inductive device 5 respectively through lead, and alarm 8 is connected with time-delay trigger 7 through lead.
The principle of work of the utility model earthquake pre-warning device is this device to be fixed on the ground, in case there is earthquake to take place; The annular steel loop 3 that box body 1 top suspends will perception arrive ground and difficult by the compressional wave of people institute perception earlier; Swing takes place and contacts with metal inductive device 5 in steel loop 3 meetings this moment, and the trigger pip of time-delay trigger 7 becomes high level by low level, triggers delay trigger circuit; Make alarm 8 energized, and in delay time, report to the police.Because the velocity of propagation of electric current is far longer than propagation of seismic wave speed, therefore report to the police and can send in former seconds even a few minutes that seismic event arrives, win the time of escape for people.
