Description

Technical Field

[0001] This utility model relates to a simulation measurement device, belonging to the field of popular science in earthquake monitoring networks, and particularly to a popular science device for simulating and determining the location of earthquake sources. Background Technology

[0002] In the context of frequent global earthquakes, popularizing earthquake science is of great importance. This includes popularizing basic earthquake knowledge. However, there is relatively little popularization about the location of the hypocenter. The hypocenter is the starting point of an earthquake, and accurately determining the hypocenter is a core part of seismological research and disaster prevention. Therefore, popularizing knowledge about the hypocenter is essential.

[0003] Chinese patent application number 201720459967.5, filed on April 27, 2017, discloses a simulated earthquake test platform, including: a control system, a reaction foundation, and a vibration table located on the reaction foundation; wherein the control system is connected to a hydraulic system, and drives the vibration table to simulate earthquake vibration through the hydraulic system; the vibration table includes: a support platform, horizontal servo actuators hinged to adjacent sides of the support platform, and several vertical servo actuators hinged to the bottom of the support platform; the hydraulic system supplies hydraulic energy to each horizontal and vertical servo actuator through a distributor and hydraulic lines; corresponding acceleration sensors are respectively provided at the bottom of the vibration table and at the hinge positions of each horizontal and vertical servo actuator; displacement and acceleration signal data of the vibration table are collected through each acceleration sensor. Although this design uses a hydraulic system to drive the vibration table to simulate earthquake vibration, it still has the following drawbacks:

[0004] This design can only simulate the vibration process of an earthquake, but cannot display the location of the epicenter, nor can it provide popular science information about the location of the epicenter.

[0014] The outer surface of the vibration sensor is connected to the inner surface of the fixing ring. One end of the fixing ring located on the left side of the vibration sensor is connected to one end of the first inclined rod, and one end of the fixing ring located on the right side of the vibration sensor is connected to one end of the second inclined rod.

[0015] The measuring device includes a housing, which is frustum-shaped, with a measuring groove at the bottom and a hollow structure in the middle. The bottom of the housing is filled with vibration-guiding material.

[0016] The display device includes a display housing, a display main controller, and a display panel.

One end of the left adjustment frame is provided with a left cylindrical end, and the middle part of the left cylindrical end is a hollow structure. The other end of the left adjustment frame is perpendicularly connected to one end of the middle adjustment frame.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This utility model discloses a popular science device for simulating and determining the location of an earthquake source. The device includes multiple measuring devices and a display device. Each measuring device includes a measuring groove and a vibration sensor. The measuring groove includes a first fixed rod and a second fixed rod. The first fixed rod is connected to the left side of the vibration sensor, and the second fixed rod is connected to the right side of the vibration sensor. The vibration sensor is connected to the display device via a signal connection. In application, multiple measuring devices are first placed in random positions on a table. Then, the multiple measuring devices report their three-dimensional position coordinates to the display device. The display device then displays the positions of all measuring devices to simulate the effect of displaying the position of a measuring station at the center of a seismic network. Next, a random position on the table is tapped, causing the table to vibrate. The measuring groove receives the vibration and transmits it to the vibration sensor. The vibration sensor then receives an electrical signal and obtains the arrival time of the vibration based on the electrical signal. All arrival times are then sent to the display device. The display device calculates the location coordinates of the earthquake source based on the three-dimensional position coordinates and arrival times. Finally, the display device displays the location coordinates of the earthquake source. The advantages of this utility model also include:

[0023] First, it can obtain the location of the earthquake source by measuring vibration, thus having the function of displaying the location of the earthquake source. It can also simulate the process of obtaining the location of the earthquake source in actual earthquake observation, which has a good effect on popularizing the science of the location of the earthquake source.

[0024] Secondly, by connecting the vibration sensor to the measuring slot through the first and second fixing rods, the vibration can not only be transmitted to the vibration sensor, but also the vibration sensor can be limited to prevent the vibration sensor from shifting when the table vibrates greatly. This makes the vibration sensor match the three-dimensional position coordinates it sends, resulting in a better measurement effect for the arrival time. Therefore, the accuracy of the vibration source position coordinates is high.

[0025] Thirdly: The measuring device is truncated cone-shaped, making it easy to grasp when placing it; there is no need to directly grasp the vibration sensor to avoid damaging it.

[0026] Therefore, this utility model has the function of displaying the location of the seismic source, and the accuracy of the seismic source location coordinates is high.

[0027] 2. In this utility model, a popular science device for simulating and determining the location of an earthquake source, a fixing ring is fitted around the outside of the vibration sensor. The left side of the fixing ring is connected to a first inclined rod, and the right side of the fixing ring is connected to a second inclined rod. The other ends of the first and second inclined rods are connected to a measuring groove. In application, the vibration sensor is limited by the fixing ring, the first inclined rod, and the second inclined rod to ensure a stable connection between the vibration sensor and the measuring groove. Therefore, this utility model has a good limiting effect on the vibration sensor.

[0028] 3. In this utility model, a science popularization device for simulating and determining the location of an earthquake source, the measuring device includes a shell. The shell has a hollow structure, and the bottom of the shell is filled with a vibration-guiding material. In application, the vibration of the tabletop is absorbed by the vibration-guiding material, which then transmits the vibration. The vibration-guiding material can transmit vibration efficiently, so the vibration sensor receives the vibration quickly, resulting in accurate measurement of the arrival time. Therefore, this utility model provides accurate measurement of the arrival time.

[0029] 4. In this utility model, a science popularization device for simulating and determining the location of an earthquake source, the display device includes a display shell, a main display controller, and a display panel. The main display controller is connected to the display panel and the vibration main control via signals. The display shell is connected to an adjustment frame. In application, the vibration main control transmits the three-dimensional position coordinates and arrival time to the main display controller, which then calculates the earthquake source position coordinates. The display panel then displays the earthquake source position coordinates. When the angle of the display panel is not suitable for viewing, the adjustment frame can be rotated to adjust the viewing angle of the display panel. Therefore, this utility model allows for adjustment of the viewing angle.

[0030] 5. In this utility model, a science popularization device for simulating and determining the location of an earthquake source includes a striking rod, which comprises a rod body and a striking block. In use, one end of the rod body is held, and the striking block is used to strike the tabletop to achieve a vibration effect. Using the striking rod is convenient and simulates the effect of an earthquake releasing energy from its epicenter, thus providing a good simulation of the earthquake's occurrence process. Therefore, this utility model provides a good simulation of the earthquake's occurrence process. Attached Figure Description

[0056] The display device 2 includes a display housing 21, a display main controller 22, and a display panel 23. The display main controller 22 is located inside the display housing 21. The display main controller 22 is signal-connected to the display panel 23 and to the vibration main controller 15. The display panel 23 is located on top of the display housing 21.

[0057] The left side of the display housing 21 is connected to the left side of the adjustment frame 3, and the right side of the display housing 21 is connected to the right side of the adjustment frame 3. The movement stroke of the adjustment frame 3 is a rotation around the plane where the display housing 21 is located.

[0058] The adjustment frame 3 includes a left adjustment frame 31, a middle adjustment frame 32, and a right adjustment frame 33.

[0060] The device includes a striking rod 4, which includes a rod body 41 and a striking block 42, with one end of the rod body 41 connected to the middle of the striking block 42.

[0061] The supplementary description of this utility model is as follows:

[0062] The calculated location coordinates of the earthquake source according to this utility model are: the main control unit 22 first obtains the location coordinates (x, y) of multiple measuring devices 1. i y i , z i ) and arrival time t i Then, multiple position coordinates (x i y i , z i ) and arrival time t i Substitute the following equations into the calculation:

[0063]

[0064] t = t i t0

[0065] In the formula: x i Let x0 be the x-coordinate of the multiple measuring devices 1, and y be the x-coordinate of the seismic source. i Let y0 be the ordinate of multiple measuring devices 1, z be the ordinate of the seismic source, and z be the ordinate of the seismic source. i The vertical coordinates of multiple measuring devices 1 are given (in reality, the vertical coordinate values ​​of measuring stations are different; in this invention, since the measuring devices 1 are all on the desktop 6, the vertical coordinate Z is given). i(Similarly, this is a simulation calculation), z0 is the vertical coordinate of the earthquake source, v is the seismic wave propagation velocity, and t is the time difference between the arrival time and the earthquake occurrence time. i t0 represents the arrival time of multiple measuring devices 1, and t0 represents the time of the earthquake.

[0066] Then, the coordinates of the epicenter (x0, y0, z0) and the time of the earthquake t0 are obtained. The display device then displays the position of the epicenter on the desktop 6 (i.e. the position of the tapping point 8) and the time of the earthquake.

[0067] The seismic network described in this utility model is the core infrastructure of the earthquake monitoring system, which includes tens of thousands of monitoring stations. When an earthquake occurs, the monitoring stations capture seismic wave signals and transmit them to the seismic network center, which then generates earthquake information such as the epicenter location.

[0068] Example 1:

[0069] Please see Figure 1 — Figure 15 A popular science device for simulating and determining the location of an earthquake source is disclosed. The device includes multiple measuring devices 1 and a display device 2. The bottom of each measuring device 1 includes a measuring groove 11 and a vibration sensor 12. The measuring groove 11 includes a left wall 111 and a right wall 112. One end of a first fixing rod 13 is fixed to one end of the left wall 111, and the other end of the first fixing rod 13 is connected to the left side of the vibration sensor 12. The right side of the vibration sensor 12 is connected to one end of a second fixing rod 14, and the other end of the second fixing rod 14 is connected to one end of the right wall 112. The vibration sensor 12 is connected to the display device 2 via a signal line 193. The number of measuring devices 1 is greater than or equal to five. Preferably, the vibration sensor 12 includes a sensing unit 121, a vibration control unit 122, and a positioning module 123. The sensing unit 121 is connected to the vibration control unit 122, the vibration control unit 122 is connected to the positioning module 123, and the vibration control unit 122 is connected to the display device 2.

[0070] In application, multiple measuring devices 1 are first randomly placed on the tabletop 6. The placement of the measuring devices 1 is as irregular as possible, and multiple measuring devices 1 cannot be located on the same circumference. This simulates the effect of measuring stations being located throughout the country and facilitates the generation of as many different three-dimensional position coordinates and arrival times as possible, so as to ensure the accuracy of subsequent calculation of the earthquake source position coordinates. Then, multiple positioning modules 123 are used to obtain the three-dimensional position coordinates of multiple vibration sensors 12. The three-dimensional position coordinates of multiple vibration sensors 12 are then sent to the display main control 22 to simulate the effect of multiple measuring stations sending three-dimensional position coordinates to the network center. Then, any point on the tabletop 6 is tapped to simulate the vibration process generated when an earthquake occurs. The tabletop 6 then vibrates from the tapped point, and the vibration is received by the measuring slot 11. The measuring slot 11 then transmits the vibration to the first fixed rod 13. The vibration is transmitted to the sensing unit 121 via the second fixed rod 14, the first fixed rod 13, and the second fixed rod 14. The sensing unit 121 measures the vibration to obtain an electrical signal, which is then sent to the vibration master controller 122. The vibration master controller 122 optimizes the electrical signal to obtain an optimized electrical signal. The vibration master controller 122 samples the optimized electrical signal to capture the amplitude value of the electrical signal at a precise moment and then determines the arrival time (here, the arrival time can be determined by an amplitude threshold or by waveform characteristics). The vibration master controller 122 then sends all arrival times to the display device 2. The display device 2 then substitutes all three-dimensional position coordinates and arrival times into the equation to calculate the source position coordinates and the earthquake occurrence time, that is, the striking position coordinates and striking time. The display device 2 then displays the aforementioned information, in the following format: Figure 15 As shown, the waveform diagram collected by the vibration sensor 12 is also displayed next to the vibration sensor 12 on the display device 2; in the aforementioned process, the precise time can be obtained by the clock source in the vibration master controller 122; the first fixed rod 13 and the second fixed rod 14 transmit to the vibration sensor 12 while limiting the vibration sensor 12, so the vibration sensor 12 can measure the vibration at its location; the number of measuring devices 1 is at least five, so as to obtain the three-dimensional position coordinates and arrival time of the five measuring devices 1, thereby completing the solution and verification of the equation.

[0071] Example 2:

[0072] The basic content is the same as in Example 1, except that:

[0073] Please see Figure 1 — Figure 7The left side of the vibration sensor 12 is connected to one end of the first inclined rod 131, and the other end of the first inclined rod 131 is connected to one end of the left wall 111 of the groove. The right side of the vibration sensor 12 is connected to one end of the second inclined rod 141, and the other end of the second inclined rod 141 is connected to one end of the right wall 112 of the groove. The outer surface of the vibration sensor 12 is connected to the inner surface of the fixing ring 124. One end of the fixing ring 124 located on the left side of the vibration sensor 12 is connected to one end of the first inclined rod 131, and one end of the fixing ring 124 located on the right side of the vibration sensor 12 is connected to one end of the second inclined rod 141. Preferably, there are two first fixing rods 13, two first inclined rods 131, two second fixing rods 14, and two second inclined rods 141. The first fixing rods 13 and 14 are symmetrically distributed along the vibration sensor 12, and the first inclined rods 131 and 141 are symmetrically distributed along the vibration sensor 12.

[0074] In application, the first inclined rod 131, the second inclined rod 141, and the fixing ring 124 further limit the vibration sensor 12 to stabilize its position. The first inclined rod 131, the first fixing rod 13, and the left wall 111 of the groove form a stable triangular connection, and the second inclined rod 141, the second fixing rod 14, and the right wall 112 of the groove form a stable triangular connection, further improving structural stability. The number of the first fixing rod 13, the second fixing rod 14, the first inclined rod 131, and the second inclined rod 141 can be increased or decreased according to requirements, and their distribution can be symmetrical along the vibration sensor 12 to achieve a better limiting effect.

[0075] Example 3:

[0076] The basic content is the same as in Example 1, except that:

[0077] Please see Figure 1 — Figure 7 The measuring device 1 includes a housing 19, which is frustum-shaped. The bottom of the housing 19 is a measuring groove 11, the middle part of the housing 19 is a hollow structure 191, and the bottom of the housing 19 is filled with a vibration guiding material 192.

[0078] In application, when the desktop 6 vibrates, the vibration guiding material 192 enhances the receiving effect of the shell 19 on the vibration of the desktop 6. The vibration guiding material 192 can efficiently transmit vibration, so the vibration sensor 12 receives the vibration faster, and the arrival time measurement is accurate.

[0079] Example 4:

[0080] The basic content is the same as in Example 1, except that:

[0081] Please see Figure 1 — Figure 13 The display device 2 includes a display housing 21, a display main controller 22, and a display panel 23. The display main controller 22 is located inside the display housing 21 and is signal-connected to the display panel 23 and the vibration main controller 15. The display panel 23 is located on top of the display housing 21. The left side of the display housing 21 is connected to the left side of the adjustment frame 3, and the right side of the display housing 21 is connected to the right side of the adjustment frame 3. The adjustment frame 3 rotates around the plane of the display housing 21. The adjustment frame 3 includes a left adjustment frame 31, a middle adjustment frame 32, and a right adjustment frame 33. One end of the left adjustment frame 31 has a left cylindrical end 311, the middle of which is hollow. The other end of the left adjustment frame 31 is perpendicularly connected to one end of the middle adjustment frame 32, and the other end of the middle adjustment frame 32 is perpendicularly connected to one end of the right adjustment frame 33. The other end of the right adjustment frame 33 has a right cylindrical end 331, the middle of which is hollow. A left rotating shaft 211 is located on the left side of the display housing 21, one end of which is inserted into the left cylindrical end 311. A right rotating shaft 212 is located on the right side of the display housing 21, one end of which is inserted into the right cylindrical end 331. Preferably, the inner surface of the left cylindrical end 311 is damped and the outer surface of the left rotating shaft 211 is damped, and the inner surface of the right cylindrical end 331 is damped and the outer surface of the right rotating shaft 212 is damped.

[0082] In application, when the main display controller 22 receives multiple arrival times, it substitutes these arrival times and their corresponding three-dimensional position coordinates into an equation for calculation to obtain the source coordinates and earthquake occurrence time. Then, the main display controller 22 sends the source coordinates and earthquake occurrence time to the display panel 23, which displays them. If the viewing angle of the display panel 23 is uncomfortable, the angle between the adjustment bracket 3 and the display panel 23 can be adjusted. When the display panel 23 needs to be upright, first lift the display panel 23, then move the middle adjustment bracket 32 ​​downwards. At this time, the middle adjustment bracket 32 ​​moves the left adjustment bracket 31 downwards. When one end of the right adjustment bracket 33 moves downward, the left cylindrical end 311 and the right cylindrical end 331 rotate around the left rotation axis 211 and the right rotation axis 212 to adapt, so the angle between the adjustment bracket 3 and the display panel 23 becomes smaller, and the display panel 23 appears to be in a vertical position. When the display panel 23 needs to be placed horizontally, first pick up the display panel 23, and then move the middle adjustment bracket 32 ​​upward. At this time, the middle adjustment bracket 32 ​​drives one end of the left adjustment bracket 31 and one end of the right adjustment bracket 33 to move upward. At this time, the left cylindrical end 311 and the right cylindrical end 331 rotate around the left rotation axis 211 and the right rotation axis 212 to adapt, so the angle between the adjustment bracket 3 and the display panel 23 becomes larger, and the display panel 23 appears to be in a horizontal position.

[0083] Example 5:

[0084] The basic content is the same as in Example 1, except that:

[0085] Please see Figure 1 — Figure 14 The device includes a striking rod 4, which includes a rod body 41 and a striking block 42, with one end of the rod body 41 connected to the middle of the striking block 42.

[0086] When using it, first hold one end of the rod 41, then move the rod 41 toward the table 6, and then strike the table 6 with the striking block 42 to make the table 6 vibrate. It is more convenient to use the striking rod 4 to strike, and one end of the striking block 42 can be used to strike the table 6, so the force point on the table 6 is smaller, and the vibration effect on the table 6 is better.

[0087] Example 6:

[0088] The basic content is the same as in Example 1, except that:

[0089] Please see Figure 1 — Figure 13The vibration control unit 122 is connected to the WIFI signal transmitting module 5, the WIFI signal transmitting module 5 is connected to the WIFI signal receiving module 51, and the WIFI signal receiving module 51 is connected to the display control unit 22.

[0090] In application, the vibration controller 122 sends multiple arrival times to the WIFI signal transmitting module 5, which then sends the multiple arrival times to the WIFI signal receiving module 51, and finally the WIFI signal receiving module 51 sends the multiple arrival times to the display controller 22. When there are many measuring devices 1, it is more convenient to transmit arrival times via WIFI. Moreover, it does not limit the distance between the measuring device 1 and the display device 2, so it is convenient to place the measuring device 1 and also convenient to store the measuring device 1.
