Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further clarified by combining the specific drawings.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

It is known to those skilled in the art that when an earthquake occurs, the dislocation of the earth crust causes intermittent intensity changes among the earth magnetic field S, N, and if information about the change of the earth magnetic field before the earthquake can be captured, the earthquake can be predicted. Therefore, as shown in fig. 1, the present invention provides an earthquake predictor made of a magnetic field detection device and a magnetic sensor, which comprises a box 10, a thimble 20, a lever 30, a fixed base 60 and an a/D conversion circuit.

The box body 10 has an accommodating space 11, and a supporting surface 12 extending horizontally is provided at the bottom of the accommodating space 11. In the present invention, the box 10 is used as a bearing component of the earthquake predictor, and plays a role of supporting and fixing, and is used for installing and arranging parts such as the thimble 20, the lever 30, the fixed seat 60, and the like.

The thimble 20 is vertically movably disposed on the supporting surface 12, and the thimble 20 is vertically movable on the supporting surface 12 to facilitate adjustment of the height of the strong magnetic bead 50.

The fulcrum position of the lever 30 is arranged at the upper end of the thimble 20 through a micro glass ball 40 with a taper hole, two cantilevers of the lever 30 are provided with downwardly extending support rods 31, the bottom ends of the support rods 31 are respectively fixed with strong magnetic beads 50, and the S poles of the strong magnetic beads 50 are arranged outwards; the fixed seat 60 is arranged on the supporting surface 12 and used for installing and fixing the magnetic sensor, and the fixed seat 60 is arranged at the supporting surface 12 corresponding to the strong magnetic bead 50 on the lever 30 when the strong magnetic bead 50 is in a standing state, so that the magnetic sensor arranged on the fixed seat 60 and the strong magnetic bead 50 are arranged at an interval; the A/D conversion circuit is electrically connected with the magnetic sensor and is used for displaying a voltage signal output by the magnetic sensor.

The earthquake predictor provided by the invention utilizes the principle that like poles of magnetic fields repel and opposite poles attract, when in specific use, two strong magnetic beads 50, specifically, a strong micro magnetic bead A and a strong micro magnetic bead B shown in figure 1 are fixed at the bottom end of a supporting rod 31, S poles of the strong micro magnetic bead A and the strong micro magnetic bead B are arranged outwards, then a lever 30 is arranged at the upper end of a thimble 20 through a micro glass ball 40 with a taper hole in the middle, and the lever 30 and the supporting rod 31 are both made of light nonmagnetic materials;

at this time, the powerful micro magnetic beads a and the powerful micro magnetic beads B at the bottom end of the supporting rod 31 are suspended in the accommodating space 11 of the box body 10, and the lever 30 suspended in the box body 10 is stopped at a position of 45 degrees in the direction of the earth magnetic field S, N under the action of the repulsion of the earth S-pole magnetic field and the attraction of the earth N-pole magnetic field. When earthquake happens in the process of breeding a geoball, S, N polar magnetic field of the earth has strong and weak intermittent frequency change of 60-120 times per minute, S polar magnetic field of the earth is weakened, and the lever 30 suspended in the box body 10 is turned to be close to S polar of the earth; the earth S pole magnetic field becomes stronger, and the lever 30 suspended in the box 10 turns away from the earth S pole; by repeating the above steps, the lever 30 suspended in the cartridge 10 and fixed with the strong magnetic beads 50 swings in the horizontal direction and the swing frequency changes according to the strength and frequency of the magnetic field. Thus, the change of the intensity of the earth magnetic field is converted into the mechanical energy of the left-right swing of the lever 30.

In the invention, the magnetic sensor can be a linear magnetic sensor, for example, the magnetic sensor with the model number of CC6501 is a three-terminal IC (integrated circuit) and is a non-contact device which is very sensitive to a magnetic field, the linear output range of the CC6501 linear magnetic sensor is wider, the output voltage of an OUT pin is half of the power supply voltage under the condition of no magnetic field, the output voltage is close to the power supply voltage under the magnetic field of an N pole, the output voltage is close to zero under the magnetic field of an S pole, and particularly, under the condition of the power supply voltage of 5V, the OUT pin can have the characteristic of linear change along with the magnetic field at 0.5-4.5V. In the invention, the magnetic sensor is arranged on a fixed seat 60, the fixed seat 60 is arranged at the corresponding supporting surface 12 when the strong magnetic bead 50 on the lever 30 is in a standing state, and the magnetic sensor arranged on the fixed seat 60 is arranged close to and at an interval with the strong magnetic bead 50;

when the S and N pole magnetic fields of the earth fluctuate, the strength change of the magnetic field of the earth can be converted into the change of the voltage output magnitude. Specifically, the magneto sensor before the 3-level earthquake has the voltage output of +/-20 mu V, and the magneto sensor before the 6-level earthquake has the voltage output of +/-75 mu V.

In the invention, the A/D conversion circuit is specifically made of a GC7107C three-and-half LED and an A/D converter, and the GC7107 is a high-performance and low-power-consumption integrated circuit and comprises 7 sections of decoders and a display driver, and can directly drive the LED. Therefore, once an earthquake happens, the change of the intensity of the earth magnetic field is converted into voltage which can be directly displayed by an LED nixie tube, and the magnitude of the earthquake can be directly forecasted according to the display voltage.

Further, according to the present invention, in a specific embodiment of the present invention, the earthquake predictor further includes a voltage amplifier and an array display module, wherein the voltage amplifier is electrically connected to the magnetic sensor and is configured to amplify a weak voltage signal output by the magnetic sensor;

in the embodiment of the invention, the voltage amplifier adopts an LM358 chip, and specifically, the voltage amplifier consists of a dual operational amplifier LM358, wherein an operational amplifier A and a triode Q1 are in forward input amplification, an operational amplifier B and a triode Q2 are connected into reverse amplification, a resistor R5, a resistor R6, a resistor R7 and an adjustable resistor W1 form a voltage comparison balance input circuit, under the condition that the earth magnetic field is stable, the output voltage of an OUT pin of a magnetic sensor is not fluctuated, the adjustable resistor W1 is adjusted to enable the voltages of output ends 1 and 7 of A, B of the LM358 to be zero, and the collectors of the triode Q1 and the triode Q2 are not output voltage; under the condition that the output voltage of the magnetic sensor does not fluctuate, the output parts of the two positive and negative amplifiers are zero.

The array display module comprises an array display circuit formed by two LM3914 integrated circuits, and the LM3914 integrated circuit controls the quantity of the lighted light-emitting diodes by controlling the voltage of the 5 th pin control end.

In the embodiment of the invention, the LM3914 IC can sequentially light 10 leds, and as shown in fig. 2, the LM3914 IC3 is connected to sequentially light 10 leds to the left, and the LM3914 IC4 is connected to sequentially light 10 leds to the right. Once an earthquake occurs, the earth crust in the earthquake rubs, the intensity of the earth magnetic field S and the intensity of the N pole are affected, and the frequency changes, at this time, the strong magnetic beads 50 suspended in the box body 10 are repelled by the earth magnetic field S pole, the N pole is attracted, further, the 45-degree angle of the N pole on the earth S and the N pole can synchronously swing in the left-right amplitude and the frequency, the variation of the intensity of the magnetic field is different, the amplitude of the left-right swing of the strong magnetic beads 50 on the lever 30 is also different, the voltage output by the magnetic sensor is also different, and the voltage amplifier is used for synchronously amplifying the voltage, so that an array circuit formed by the LM3914 can clearly and visually see the variation of the intensity and the frequency of the magnetic field of the earth, and can light a plurality of light emitting diodes according to the variation, and can predict the grade of the earthquake.

Further, according to the present invention, in a specific embodiment of the present invention, the earthquake predictor further comprises a precision voltage-stabilized power supply and a standby power supply, wherein the precision voltage-stabilized power supply is used for supplying electric energy to the magnetic sensor, the voltage amplifier and the array display module, and the standby power supply is used for emergency use in case of power failure; specifically, as shown in fig. 1, IC6 and IC7 constitute a precision regulated power supply and a standby power supply.

Further, according to the present invention, in a specific embodiment of the present invention, the earthquake predictor further includes a glass horizontal bubble 13 and an adjustable foot pin 14, wherein the glass horizontal bubble 13 is provided with two supporting surfaces 12 at the bottom of the accommodating space 11; the number of the adjustable pins 14 is at least three and is positioned at the bottom of the box body 10; the adjustable foot nails 14 can adjust the level of the supporting surface 12 at the bottom of the accommodating space 11 and judge the level degree through the glass level bubble 13.

In the invention, the earthquake predictor also comprises a box cover 15, wherein the box cover 15 is arranged at the upper part of the box body 10 and is used for sealing the accommodating space 11 so as to create a measuring environment which is not influenced by the external environment in the box body 10.

The invention provides an earthquake predictor which has the disadvantages that the pointing location of the earthquake to be generated cannot be specifically guided, however, when the earthquake is predicted, the variation of the magnetic field of the earth in the epicenter is different from that of the magnetic field of the earth around the epicenter, the variation of the magnetic field in the epicenter is strong, the variation of the magnetic field around the epicenter is weak, the signal near the epicenter is strong, and the signal far from the epicenter is weak.

Specifically, as shown in fig. 3, 25 small areas are divided into a large area, and the 25 small areas are all provided with the earthquake prediction instruments, and if the voltage measured in the 5 area is 3V, and the voltages measured in the 1-4 area and the 6-9 area are 2.5V, it is determined that the 5 area will have an earthquake of more than 3 levels and less than 4 levels.

The earthquake predictor provided by the invention can send earthquake early warning information to people more timely by means of the force of the Internet, and remind people to avoid disasters timely.

The foregoing shows and describes the general principles, essential features, and inventive features of this invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
