The primary information monitored by traditional earthquake alarms is usually seismic wave information, namely ground tilting and micro-motions caused by the pre-release of ground stress before an earthquake. This limited information monitoring by traditional earthquake alarms affects their earthquake early warning effectiveness. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1:

[0030] This utility model provides an earthquake and geological disaster monitoring and alarm device, referenced Figures 1 to 3 As shown, the earthquake geological disaster monitoring and alarm device includes an alarm housing 1, a monitoring device 2, and an alarm device 3.

[0031] The monitoring device 2 is installed inside the alarm housing 1. The monitoring device 2 includes an electric field signal receiver 21, a magnetic pendulum assembly 22, and an electromagnetic sensor 23. The electric field signal receiver 21 is used to receive the electric field signal before the earthquake. The magnetic pendulum assembly 22 is vertically suspended. The electromagnetic sensor 23 is equipped with an electromagnetic induction coil 231, which is located directly below the magnetic pendulum assembly 22. The electromagnetic sensor 23 can sense the electromagnetic signal when the magnetic pendulum assembly 22 swings and the electromagnetic wave signal before the earthquake.

[0032] The alarm device 3 is installed inside the alarm housing 1 and is electrically connected to the monitoring device 2.

[0033] Before an earthquake occurs, ground tilting and micro-motion will occur due to the pre-release of ground stress, which will also generate certain changes in electric field and magnetic field. When ground tilting and micro-motion occur, the magnetic pendulum assembly 22 will swing, thereby generating a voltage in the electromagnetic induction coil 231. The electromagnetic sensor 23 can monitor the electromagnetic signal by sensing the voltage signal of the electromagnetic induction coil 231, and can also monitor the pre-earthquake electromagnetic wave signal. At the same time, the electric field signal receiver 21 receives the pre-earthquake electric field signal in real time.

[0034] In practical applications, when the monitoring device 2 monitors at least one of the pre-earthquake electric field signal, the electromagnetic signal of the electromagnetic induction coil 231 when the magnetic pendulum assembly 22 swings, and the pre-earthquake electromagnetic wave signal, it will issue an alarm to warn of an earthquake.

[0035] This invention monitors earthquakes from three aspects: the pre-earthquake electric field signal, the electromagnetic signal of the electromagnetic induction coil 231 when the magnetic pendulum assembly 22 swings, and the pre-earthquake electromagnetic wave signal. This allows for the prediction and monitoring of earthquake occurrences. Combined with the alarm device 3, the early warning effect is significant.

[0036] Example 2:

[0037] Example 2 is based on Example 1:

[0038] like Figures 1 to 3 As shown, the alarm housing 1 includes a base and an upper shell disposed on the upper side of the base. The upper shell has a first accommodating cavity 11 and a second accommodating cavity 12 arranged sequentially from the inside to the outside.

[0039] The magnetic pendulum assembly 22 is disposed in the first accommodating cavity 11; the electric field signal receiver 21 is disposed in the second accommodating cavity 12 and is located at the upper position.

[0040] As an optional implementation, the electromagnetic sensor 23 includes an amplifier circuit 232 and a frequency divider circuit 233.

[0041] When the magnetic pendulum assembly 22 swings before the vibration, the electromagnetic induction coil 231 generates a small induced voltage. The amplifier circuit 232 is used to amplify this induced voltage, thereby amplifying the electromagnetic signal and facilitating the induction of the electromagnetic signal.

[0042] The frequency divider circuit 233 has a first frequency channel and a second frequency channel with different frequency bands, corresponding to the electromagnetic signal and the pre-earthquake electromagnetic wave signal, respectively. In this way, the electromagnetic signal and the pre-earthquake electromagnetic wave signal can be processed in a targeted manner, thereby realizing the monitoring of the electromagnetic signal and the pre-earthquake electromagnetic wave signal.

[0043] Specifically, the first frequency channel corresponds to a frequency band of 0~10Hz, and the second frequency channel corresponds to a frequency band of 10~20Hz.

[0044] As an optional implementation, the magnetic pendulum assembly 22 includes a pendulum wire 222 and a magnetic pendulum 223. The top end of the pendulum wire 222 is connected to the alarm housing 1, and the bottom end of the pendulum wire 222 is connected to the magnetic pendulum 223. The magnetic pendulum 223 is located directly above the electromagnetic induction coil 231.

[0045] Thus, when the ground tilts or tremors occur before an earthquake, the magnetic pendulum 223 swings under the traction of the pendulum wire 222, and the electromagnetic induction coil 231 generates electromagnetic induction.

[0046] As an optional implementation, the magnetic pendulum assembly 22 includes a threaded adjustment member 221. The top of the alarm housing 1 is provided with a threaded hole in the vertical direction. The threaded adjustment member 221 is threadedly connected in the threaded hole, and its bottom end is connected to the top end of the pendulum wire 222.

[0047] In actual use, rotating the threaded adjustment component 221 causes it to move axially under the guidance of the threaded hole, thereby pulling the magnetic pendulum 223 to move via the oscillating wire 222. This allows for adjustment of the distance between the magnetic pendulum 223 and the electromagnetic induction coil 231, and thus adjustment of the alarm sensitivity.

[0048] The threaded structure allows for easy adjustment of the spacing simply by rotating the screw, while also providing a self-locking function to securely lock the spacing.

[0049] As an optional implementation, the alarm device 3 is configured as an audible and visual alarm device 3; the audible and visual alarm device 3 includes a first indicator light 31 and a first buzzer 32.

[0050] When the signal is abnormal, the first indicator light 31 lights up and emits light, and the first buzzer 32 sounds. The combination of sound and light has a significant warning effect.

[0051] Example 3

[0052] Example 3 is based on Example 2:

[0054] As an optional implementation, the earthquake geological disaster monitoring and alarm system further includes a master alarm device 5 and a slave alarm 4. The master alarm device 5 includes a wireless transmitter 51 and a slave receiver 52.

[0055] The wireless transmitter 51 and the sub-receiver 52 are respectively installed on the alarm housing 1 and the sub-alarm 4. The sub-receiver 52 can receive the alarm signal emitted by the wireless transmitter 51.

[0056] In practical applications, the earthquake and geological disaster monitoring and alarm device is equivalent to a monitoring and main alarm. It and the sub-alarms are set in different locations, which can cover warnings in multiple different locations. Taking a home as an example, the earthquake and geological disaster monitoring and alarm device is set in the living room, and each bedroom is equipped with a sub-alarm 4.

[0057] As an optional implementation, the sub-alarm 4 is equipped with a sub-audio-visual alarm device; the sub-audio-visual alarm device includes a second indicator light 41 and a second buzzer 42, so that the sub-alarm 4 can also issue an audio-visual warning, further improving the warning effect.

[0058] As an optional implementation, the earthquake geological disaster monitoring and alarm system also includes a monitoring, analysis and early warning platform 6, and the earthquake disaster monitoring and alarm device is communicatively connected to the monitoring, analysis and early warning platform 6.

[0059] In actual use, when an abnormal signal is detected, the earthquake geological disaster monitoring alarm will transmit the alarm signal to the sub-receiver 52 and the monitoring analysis and early warning platform 6 at the same time, so that relevant management personnel can grasp the earthquake information in a timely manner.
