[0002] 3-AXIS ELECTROMECHANICAL SEISMOMETER

[0003] Field of the Invention

[0004] The present invention relates to the axial electromechanical seismometer, which aims to obtain clearer measurements of earthquake waves by combining three axes in one device, instead of measuring the waves formed in the axes of the mechanical seismometers used in earthquake magnitude measurements in separate devices.

[0005] In particular, the present invention relates to measuring the energy generated by earthquake waves by using electromechanical measurement of the waves formed in the x, y and z axes with electronic sensors in only one device.

[0006] State of the Art

[0007] Today, the magnitude of earthquakes can be measured with many different technologies. Earthquakes have different types of waves, such as S and P waves, as well as surface waves. The waves created by earthquakes are measured by the axial oscillations of mechanical pendulums found with various devices.

[0008] Mechanical pendulum and pen seismometers are devices that have been used since ancient times to measure the magnitude of earthquakes. The weight in the seismometers is the most important part of the system. There is a pen or printer on top of the weight attached to the fixed structure. This pen moves according to the direction of the earthquake and draws lines on the paper in the rotating roll. These seismometers are made as different devices, horizontal and vertical, and thus can measure the vertical and horizontal movements of the earthquake. Different devices are required for these vertical and horizontal measurements.

[0009] The sensitivity of these systems is limited. They may not be very realistic in giving actual detailed measurements. Electronic systems are faster than these old pendulum systems, old pendulum systems are much slower. Horizontal Seismometers: It measures horizontal movement in earthquakes occurring on the ground surface and can measure both east-west and north-south lateral movements. This measurement is made with the help of a pendulum placed perpendicular to the ground. There is a weight and a pencil at the end of the pendulum. Lines are formed on the paper at the tip of the pen by oscillating according to the lateral movements occurring on the ground surface. The length and movement of these lines depend on the magnitude of the earthquake's waves.

[0010] Vertical Seismometers: It measures vertical movement in earthquakes occurring on the ground surface, and can measure movements both underground and above ground, that is, perpendicular to the ground. This measurement is made with the help of a pendulum placed parallel to the ground. There is a weight and a pencil at the end of the pendulum. The pendulum oscillates according to the vertical movements occurring on the ground surface and creates lines on the paper at the tip of the pen. The length and movement of these lines depend on the magnitude of the earthquake's waves.

[0011] Quartz Crystal Seismometers: These are systems that measure using piezoelectric properties. Earthquakes create tension in the crystal. As a result of this voltage data, the earthquake magnitude is measured.

[0012] Object of the Invention

[0013] The object of the present invention is to design mechanical seismometers to perform more detailed earthquake magnitude measurements on a single device.

[0014] The most important feature of the system is that it measures in detail the direction and axial movements of earthquakes that will occur on the earth with sensors positioned at equal distances on a spherical structure. The object of the present invention is to make detailed measurements by measuring all earthquake waves occurring in the x, y and z axes. With the help of the 112 sensors in the system, very detailed measurements can be made. Another object is to simulate earthquake movements as a result of the measurement.

[0015] The system will be able to make measurements without being affected by climatic temperatures, magnetic fields, electrostatic fields, radiation types, loud sounds and electrical and electronic noise. Description of the References in the Figures

[0025] Detailed Description of the Invention

[0026] The present invention is an electromechanical seismometer designed to measure the magnitude of an earthquake by measuring the seismic waves generated during the earthquake. When an earthquake occurs, wave oscillations occur on the earth's surface according to the earthquake strength. The earthquake magnitude can be found by measuring the duration of these wave oscillations and the distance to the earthquake center.

[0027] In order to detect earthquake waves accurately, the invention is fixed perpendicular to the ground surface on a fixed platform (5) at 90 degrees to the x, y and z axes. This stabilization process is important for accurate measurement of future waves. It is not affected by the tremors and ensures that the seismometer device remains stable and in the same position.

[0028] 3-axis electromechanical seismometer that measures the magnitude of the earthquake by recording the oscillations of the moment sphere (2) of the waves formed during the earthquake and the distances they form during the earthquake to the proximity sensors (1) and then making logarithmic calculations, characterized by comprising

[0029] • During an earthquake, the shaking caused by P and S waves being measured by moving the moment sphere (2) in three axes, namely the x, y, and z axes, on a fixed platform (5) system, the wave amplitude being measured based on the distances formed by the proximity sensors (1) inside the seismometer sphere (4) and the duration of the movement

[0030] • 112 proximity sensors (1) being in a circular shape on the seismometer sphere (4) and the moment (2) sphere, which moves with the earthquake wave, oscillates, allowing very detailed measurements to be made with the data measured by the distance sensors (1) according to time.

[0031] Earthquake waves can come from any direction and along any axis. These waves can have vertical and horizontal oscillation depending on the direction of incidence. A three-axis seismometer was designed to measure these oscillatory waves. The earthquake wave that is formed can first oscillate in three axes according to the direction of the wave energy coming to the moment sphere (2). The moment sphere (2) that oscillates according to the waves is connected to the top of the system by a helical spring (3). The helical spring (3) is a spring that is very little affected by temperature and external factors. The moment sphere (2) will be able to oscillate in very detailed ways, thanks to the helical spring (3), according to the direction of the seismic waves created by the earthquake, and these oscillations will be in the x, y and z axis directions. The movements of the moment sphere (2) towards the proximity sensors (1) located on the seismometer sphere (4) during oscillation will be recorded along with the distance and time. In other words, in order to measure the waves formed during an earthquake, the oscillating moment sphere (2) oscillates towards the proximity sensors (1) in the system and the wave amplitude is measured by the distance between the proximity sensors. The magnitude of the earthquake will be measured by applying logarithmic calculations to these records. The number of proximity sensors (1) in the seismometer sphere (4) is 112. With the help of these 112 proximity sensors (2), very detailed measurements can be made. With the help of the proximity sensors (1) at equal and symmetrical distances located on the seismometer sphere (4), the direction of the earthquake can be determined in great detail. Proximity sensors (1) operate between -5 and 5 volts. When the moment sphere (2) approaches the proximity sensor (1), the voltage will be positive, and when it moves away, the voltage will be negative. In this way, 112 separate voltage data are recorded according to the duration of the oscillation that occurs during the earthquake, thanks to the oscillation made by the 112 proximity sensors (1) and the moment sphere (2). These data can then be converted into logarithmic calculations to measure earthquake magnitude.
