[0034] Reference Signs List Figure 1and Figure 2 The application provides an anti-seismic support prediction system with an early warning earthquake function, which comprises a support assembly, the support assembly comprising a first support 100 connected between a fixed body 500 and a pipeline 400 in a vertical direction Z, the first support 100 being provided with a first sensor 001 for detecting force in the vertical direction, the first support 100 and the fixed body 500 being provided with a second sensor 002 for detecting force in the circumferential direction of the first support 100; a second support 200 connected between the fixed body 500 and the pipeline 400 in a first direction, the second support 200 being provided with a third sensor 003 for detecting force in the first direction, the first direction and the vertical direction being along a first plane, and the first direction and the vertical direction forming a first included angle, the size of the first included angle being 0-90 degrees, for example, 45 degrees; a third support 300 connected between the fixed body 500 and the pipeline 400 in a second direction, the third support 300 being provided with a fourth sensor 004 for detecting force in the second direction, the second direction and the vertical direction being along a second plane, and the second direction and the vertical direction forming a second included angle, the size of the second included angle being 0-90 degrees, for example, 45 degrees; and a controller electrically connected with the first sensor 001, the second sensor 002 and the third sensor 003, for acquiring sensing signals of the first sensor 001, the second sensor 002 and the third sensor 003, and calculating parameter information for early warning of an earthquake according to the acquired sensing signals; wherein the first support 100 and the fixed body 500 are rotatably connected, the second sensor 002 is a torque sensor, the first sensor 001, the third sensor 003 and the fourth sensor 004 are pressure or tension sensors, and the first sensor 001 is arranged in the first support 100, the third sensor 003 is arranged in the second support 200, and the fourth sensor 004 is arranged in the third support 300.
[0035] According to the scheme provided in the embodiment, the support assembly can support and stabilize the pipeline 400 to bear force from different directions in an earthquake, so that the pipeline 400 can be prevented from being damaged in the earthquake, and different sensors are arranged in combination with the structures and functions of the first support 100, the second support 200 and the third support 300, so that early warning of an earthquake can be realized by analyzing and calculating information sensed by the sensors.
[0036] In the embodiment, the first support 100, the second support 200 and the third support 300 can be in the form of rods and are made of high-strength metal materials. The pipeline 400 can be a circular pipeline 400, the pipeline 400 is provided with a hanger 410, and the first support 100 and the second support 200 are connected to different connection parts of the hanger 410 through hinges.
[0037] When the fluid in the pipeline is flammable or other dangerous substances, if an earthquake occurs, the pipeline is prone to rupture when the position of the pipeline in different directions is offset, thereby causing dangerous goods leakage or explosion accidents, and the related technology only strengthens and stabilizes the pipeline, if an earthquake occurs, due to the dispersion and imbalance of the earthquake force, these reinforcing devices are prone to damage due to stress concentration in a certain place. In a sequence of earthquakes, the first few ground vibrations are called foreshocks. Followed by the main shock, the ground shakes. The power of the main shock is enough to shake the objects on the table or enough to destroy the building. The scheme provided by the embodiment, when the foreshock first occurs, due to the vertical and horizontal earthquake forces of the foreshock, the vertical earthquake force makes the pipeline 400 vibrate up and down, and the horizontal earthquake force makes the pipeline 400 vibrate in different horizontal directions. The first sensor 001 on the first support 100 can sense the force vibrating in the vertical direction, the third sensor 003 on the second support 200 can sense the force vibrating in the first horizontal direction, and the fourth sensor 004 on the third support 300 can sense the force vibrating in the second horizontal direction. Therefore, when at least one of the first sensor, the third sensor and the fourth sensor senses a pressure of a predetermined frequency, it is determined that an earthquake exists. For example, the frequency range of the main shock wave of an earthquake is generally in the range of 2-90Hz, when the pressure change signal is related or similar to the frequency, it is determined that an earthquake exists.
[0038] Since the vibration in different horizontal directions can make the pipeline 400 swing in different length positions, when the pipeline 400 swings, the internal fluid will shake due to the inertial force, which will cause the different parts of the pipeline 400 (for example, the parts outside the first support 100, the second support 200 and the third support 300) to move in the opposite horizontal direction, thereby causing the first support 100 to rotate by a certain angle, at this time the second sensor 002 can sense the rotation angle information.
[0039] In the embodiment, when the sensing information of the first sensor 001, the second sensor 002, the third sensor 003 and the fourth sensor 004 is sensed at the same time, and the sensing information of the first sensor 001, the second sensor 002, the third sensor 003 and the fourth sensor 004 has a preset correlation, it is determined that an earthquake exists. The correlation can be that the frequencies of the sensing information are the same. In this way, it can be avoided that the pipeline 400 is stressed by a non-earthquake external force and is mistaken as an earthquake. The non-earthquake external force is generally single in direction and is difficult to cause the movement of different parts of the entire pipeline 400 and the shaking of the internal fluid, so the non-earthquake external force is difficult to cause the rotation of the first support 100, and therefore the second sensor 002 cannot sense the torque signal.
[0040] In this embodiment, since the foreshock also has a certain vibration frequency, the sensor can sense continuous multiple different signals, and since each signal is relatively weak, the sensed signals in a certain period of time can be accumulated to obtain a sensing parameter in a certain direction. The sensing parameter can be calculated by the following formula, wherein X2, Y2, and Z2 are the accumulated sensing parameters of the sensors of the first support 100, the second support 200, and the third support 300. When the change frequency of the parameter is related to the frequency of the seismic wave, it can be judged that the earthquake exists. X1, Y1, and Z1 are the single vibration sensing information of the sensors of the first support 100, the second support 200, and the third support 300, and X2, Y2, and Z2 can be calculated according to the following formula:
[0041] X2 =∑X1
[0042] Y2 =∑Y1
[0043] z2 =∑Z1
[0044] Referring to Figure 5 In some embodiments, a plurality of support assemblies are arranged at intervals along the length direction of the pipeline 400, and a fourth sensor 004 can be installed on the pipeline between two adjacent support assemblies A and B. The fourth sensor can be located at the midpoint of the support assemblies A and B. The fourth sensor 004 can be a gyroscope, and the gyroscope is electrically connected to the controller. The gyroscope can sense the position change information of the pipeline between the two adjacent support assemblies.
[0045] The position change of the part of the pipeline not supported is more obvious when vibrating. Before the earthquake occurs (i.e., before the foreshock occurs), the position of the fourth sensor 004 does not change and is at the origin. After the foreshock occurs, the position of the fourth sensor 004 changes slightly. After the foreshock occurs for the first time, the fourth sensor 004 deviates from the origin to a target point by a certain distance. The coordinate system is established at the origin and the target point, respectively. The coordinates of the fourth sensor in the first coordinate system can be, for example, The coordinates of the fourth sensor in the second coordinate system can be, for example, When the trajectory of the fourth sensor from the coordinate origin (0, 0, 0) to the target point is S, the projection of the trajectory S in one plane of the second coordinate system (r) is S'. In the formula, S is the length of the fourth sensor deviating from the coordinate origin (0, 0, 0) to the target point, and t represents the displacement time of the displacement block corresponding to the target point. The coordinate mapping relationship of the fourth sensor between the second coordinate system and the first coordinate system can be shown in the following formula:
[0046]
[0047]
[0048]
[0049] When the fourth sensor 004 is in the first quadrant of the second coordinate system, it can be determined that the pipeline 400 is twisted, and when the torque sensor senses a torque signal, the parameters and frequencies of X2, Y2, and Z2 can be combined to determine that an earthquake exists. Therefore, in the present embodiment, the controller can obtain parameter information after an earthquake occurs, and early warning can be achieved before the main earthquake occurs.
[0050] Referring to Figure 3 In some embodiments, the first support 100 includes a first connecting body 110 and a second connecting body 120, which are nested with each other, for example, the first connecting body is hollow and surrounds the second connecting body 120, and the first connecting body 110 and the second connecting body 120 are relatively movable in the length direction.
[0051] The first connecting body 110 is provided with a first limiting portion 112, and the second connecting body 120 is provided with a second limiting portion 121. The first limiting portions 112 of the first support 100 are spaced apart in the length direction of the first support 100, and the second connecting body 120 can pass through the first limiting portions. One end of the second connecting body 120 passing through the first limiting portions 112 is provided with the second limiting portion 121. The first limiting portion is provided with a pressure sensor 111, and the first limiting portion 112 and the second limiting portion 121 are provided with a first compression spring 113. When the first compression spring 113 is compressed to the limit state, the first limiting portion 112 or the second limiting portion 121 approaches each other and exerts pressure on the pressure sensor 111, thereby causing the pressure sensor to sense the pressure information. Therefore, when the earthquake occurs, the force exerted by the earthquake on the pipeline 400 in the vertical direction can be sensed by the pressure sensor 113.
[0052] The first limiting portion 112 or the second limiting portion 121 is limited in the circumferential direction of the first support 100 with the second connecting body 120, that is, no relative rotation occurs in the circumferential direction. When the pipeline is twisted around the support assembly as the axis, the first connecting body 120 and the second connecting body 110 can rotate simultaneously, thereby rotating the first trigger portion 124.
[0053] In some embodiments, the second connecting body is provided with a spring 114 at the end away from the pipeline, one end of the spring 114 abuts against the axial end of the first support 100 away from the pipeline 400, and the other end of the spring 114 abuts against the axial end of the second connecting body 120 away from the pipeline 400. Under the combined action of the first compression spring 113 and the spring 114, after the second connecting body 120 moves in the vertical direction to one end, it can be reset to the other end in time, so that the force exerted by the vertical seismic wave of each earthquake on the pipeline can be sensed by the pressure sensor 111.
[0054] Referring to Figure 4In some embodiments, the second support 200 and the third support 300 include two connecting pieces 223 and 224, which are arranged on the side of the second support 200 and connected to the fixed body 500 and the pipeline 400 through rotating connectors. The rotating direction of the rotating connector of the second support 200 is parallel to the length direction of the pipeline 400, and the rotating direction of the rotating connector of the third support 300 is perpendicular to the length direction of the pipeline 400.
[0055] In the embodiment, the second support and the third support each include a third connecting body 220 and a fourth connecting body 210 sleeved on the periphery of the third connecting body 220. The third connecting body 220 is internally provided with a third limiting portion 221, and the fourth connecting body 220 is provided with a fourth limiting portion 211. A pressure sensor 222 and a second compression spring 225 are arranged between the third limiting portion 221 and the fourth limiting portion 211.
[0056] The third connecting body 220 is axially slidable relative to the fourth connecting body 210. The fourth limiting portion 211 is fixed in the interior of the fourth connecting body 210, and the third connecting body 220 passes through the fourth limiting portion 211 in the axial direction. When the third connecting body 220 and the fourth connecting body 210 are subjected to forces in opposite directions, the second compression spring 225 is compressed. When the second compression spring 225 is compressed to the limit, the third limiting portion 221 comes into contact with the second pressure sensor 222, so that the second pressure sensor 222 senses a signal.
[0057] When the earthquake exerts a horizontal force on the pipeline, since the second support 200 and the third support 300 are arranged to be inclined relative to the vertical direction and supported between the pipeline 400 and the fixed body 500, the horizontal force is decomposed into an oblique force along the length direction of the second support 200 and the third support 300, which can be sensed by the second pressure sensor.
[0058] It can be seen that the present application is a force sensing scheme. The support assembly not only supports the pipeline in various directions, but also senses the force in the corresponding direction, thereby realizing the prediction of the earthquake.
[0059] In some embodiments, the second support 200 and the third support 300 of the same support assembly are provided in two groups and symmetrically arranged with the axis of the pipeline 400 as the symmetry axis. After such arrangement, when the pipeline 400 swings, the second support 200 and the third support 300 can support the pipeline 400 in the corresponding direction, limit the swing amplitude at the support assembly, and further make the rotation of the first support 100 more reliable. In addition, the rotating connector can play a buffering role, avoiding the deformation of the hanger 410 due to stress concentration, causing the first support 100 to tilt, and further affecting the angle sensing of the torque sensor.
[0060] In the embodiment, the stiffness coefficient of the compression spring is in a positive correlation with the diameter of the pipeline, and the stiffness of the compression spring is calculated by the following formula:
[0061]
[0062] Wherein, G is the shear modulus of elasticity [MPa] (72000-80000), d is the linear diameter [2.5mm-5mm], n is the effective number of turns [10-15n], and D is the central diameter [5-8mm]. After such setting, the parameters of the compression spring are adapted to the internal space of the bracket, so that the pressure sensor can more easily detect the pressure value generated by each vibration, and the detection is more accurate.
[0063] In some embodiments, the stiffness of the first compression spring and the second compression spring has a preset correlation with the pipe diameter of the pipeline, for example, the larger the pipe diameter of the pipeline, the greater the stiffness of the first compression spring and the second compression spring.
[0064] Continuing to refer to Figure 3 In the embodiment, the second connecting body 110 of the first bracket 100 is connected with the fixed body, the second sensor 002 is fixed on the fixed body, the first trigger part 124 is arranged on the part of the second connecting body 110 away from the axis of the second connecting body 110, the first trigger part 124 is connected with the second trigger part 012 of the second sensor 002, and when the first trigger part 124 rotates, the first trigger part 124 drives the second trigger part 012 to rotate. Wherein, the first trigger part 124 can be a protrusion fixed on the side of the first bracket 100, the second sensor 002 is cylindrical, the first bracket 100 and the second sensor 002 are arranged along the same vertical axis, when the first trigger part 124 drives the second trigger part 012 to rotate, the second sensor 002 can sense the torque information, and then send the torque information to the controller.
[0065] In some embodiments, the second bracket 200 and the third bracket 300 of the same bracket assembly are provided with two groups, and are symmetrically arranged with the axis of the pipeline 400 as the axis of symmetry, the plane where the second bracket 200 in the two groups is perpendicular to the length direction of the pipeline 400, the plane where the third bracket 300 in the two groups is parallel to the length direction of the pipeline 400, and passes through the center line of the pipeline 400.
[0066] Referring to Figure 6In some embodiments, the control terminal 700 is further connected with the controller 600 to obtain the earthquake warning information calculated by the controller 600; the communication module is configured to wirelessly or wire-connected the control terminal with the controller. The electronic valve device 800 is further arranged in the pipeline 400 and electrically connected with the control terminal 700, and when the control terminal 700 determines that there is an earthquake, the control terminal 700 sends a closing signal to the electronic valve device 800 to cut off the fluid in the pipeline.
[0067] In some embodiments, the power supply device is further configured to provide power for the controller 600, the communication module and the sensors.
[0068] In some embodiments, the fixing body comprises a mounting plate, the first support 100, the second support 200 and the third support 300 of the support assembly are connected with the mounting plate, and the controller, the communication module and the second sensor are arranged on the side of the mounting plate opposite to the support assembly.
[0069] In the embodiment, when the controller 600 calculates the earthquake warning information, the control terminal can obtain the earthquake warning information and send a closing control signal to the electronic valve device 800. After the arrangement, the coming earthquake can be predicted before the main earthquake occurs, and the electronic valve device 800 can be closed through the control terminal to avoid the fluid leakage in the pipeline 400 caused by the main earthquake and the resulting accidents. In addition, when it is determined that there is no earthquake, the fluid circulation state is maintained, so that the opening and closing of the electronic valve device 800 can be flexibly switched according to the prediction of the earthquake.
[0070] The scheme of the embodiment further comprises an alarm device 900 electrically connected with the control terminal 700, and the alarm device 900 is configured to send an alarm signal.
[0071] In some embodiments, the control terminal further comprises an earthquake intensity prediction module and an alarm information publishing module, and the control terminal can calculate the epicenter longitude and latitude, focal depth, earthquake time, earthquake magnitude and other information of the coming earthquake according to the obtained different earthquake warning information and send corresponding alarm information to the alarm device.
[0072] Since the sensors of the application can accumulate the weak signals of different frequencies generated in the foreshock to obtain the parameters of the predicted earthquake, the parameters are amplified, and the misjudgment caused by non-earthquake factors is avoided, and the prediction accuracy is improved. In addition, when the seismic force is not obvious, it is difficult for human beings to intuitively feel, but the scheme of the application can more sensitively sense the earthquake parameter information, and send a warning and close the electronic valve device in advance, effectively improving the safety of personnel and facilities and winning time for orderly evacuation.
