Laminated rubber has a large vertical bearing capacity and vertical stiffness, and at the same time has good flexibility in the horizontal direction. Lead rubber bearings can extend the natural vibration period of the superstructure through the good horizontal shear deformation of the rubber and the lead core, reduce the seismic response of the superstructure, and achieve a seismic isolation effect.

[0030] Embodiment 1

[0031] like Figure 1 As shown, the seismic isolation bearing provided by the embodiment of the present invention includes a top plate 11, a bottom plate 12, a lead column 4, a rubber layer 3, a steel plate layer 2 and a sensor 5. Among them, the top plate 11, the bottom plate 12 and the steel plate layer 2 are all circular structures, the steel plate layer 2 is provided with a center hole 22, and the nine layers of steel plate layers 2 and the eight layers of rubber layers 3 are alternately stacked between the top plate 11 and the bottom plate 12. The lead column 4 penetrates the center hole 22 and the rubber layer 3 of each layer of the steel plate layer 2, and the upper and lower ends of the lead column 4 are fixedly connected to the top plate 11 and the bottom plate 12 respectively. Among them, both the top plate 11 and the bottom plate 12 are provided with mounting holes for installation, and the sensor 5 includes a resistive strain gauge.

[0032] like Figure 2 As shown, the sheet structure of the commonly used resistance strain gauge has two connection points 51 (i.e., welding points) for the lead-out circuit part, and the two connection points 51 are located on the same side of the resistance strain gauge. In the conventional installation method, the other side of the resistance strain gauge away from the connection point 51 is completely bonded and fixed on the surface of the steel plate layer 2 to improve the bonding quality of the resistance strain gauge on the steel plate layer 2, so as to achieve accurate measurement of the deformation of the steel plate layer 2. Accordingly, the connection point 51 of the resistance strain gauge and the wire 6 fixedly connected to the connection point 51 are both buried and pressed in the rubber layer 3.

[0033] The applicant has discovered through research that, for the resistive strain gauge installed by the conventional method, when a large horizontal relative displacement occurs between the top plate 11 and the bottom plate 12 of the seismic isolation bearing and misalignment yields, and a large deformation displacement occurs in the rubber layer 3 relative to the steel plate layer 2, the deformation of the rubber layer 3 drags the wire 6, causing the connection point 51 to be disconnected, thereby affecting the normal transmission of the signal of the resistive strain gauge.

[0034] like Figure 1 , Figure 3 , Figure 4 as well as Figure 5 As shown, the fifth steel plate layer 2 in the seismic isolation bearing of the embodiment of the present invention is provided with four through holes 21 in the thickness direction, and the four through holes 21 are evenly and symmetrically distributed around the central hole 22 of the steel plate layer 2. The number of sensors 5 is 4, and each sensor 5 is installed on the upper surface of the fifth steel plate layer 2, and the wire 6 connecting the sensor 5 is led out from the rubber layer 3 on the lower surface of the fifth steel plate layer 2 by means of the through hole 21. Among them, the through hole 21 is a circular hole or a strip hole, and the through hole 21 is also used to accommodate the connection point 51 between the resistance strain gauge and the wire 6. This embodiment adopts a strip hole structure to accommodate two connection points 51 on the resistance strain gauge.

[0035] When the resistance strain gauge is installed, the four resistance strain gauges are evenly distributed around the lead core column 4, and the surface on the same side as the connection point 51 of each resistance strain gauge is bonded and fixed to the upper surface of the steel plate layer 2, and the two connection points 51 on the resistance strain gauge are located in the through hole 21 to ensure the flatness and bonding quality of the resistance strain gauge installation. Among them, the part of the wire 6 in the through hole 21 can be set to a spiral or folded shape to retain the tensile redundancy of the deformation of the wire 6.

[0036] When the installation is completed, the rubber layer 3 and the steel plate layer 2, the rubber layer 3 and the top plate 11, and the rubber layer 3 and the bottom plate 12 are connected by vulcanization bonding to ensure good shock absorption performance with the steel plate layer 2 after the rubber is cured. Among them, each wire 6 connected to the resistance strain gauge is pressed by the rubber layer 3 on the lower surface of the steel plate layer 2 before vulcanization bonding and led out to the outside of the seismic isolation support.

[0037] The test method of the seismic isolation support is as follows: fix the vertical seismic isolation support bottom plate 12, apply thrust to the top plate 11 in the horizontal direction perpendicular to the lead core column 4 to tilt the lead core column 4 to a preset tilt angle and simultaneously detect the on / off state of the resistance strain gauge. Among them, at least one of the four conductors 6 is guaranteed to be consistent with the force direction.

[0038] Table 1

[0039]

[0040] It should be noted that the preset tilt angle is the angle between the length direction of the lead column 4 and the vertical direction of gravity. The difference between the comparative embodiment and the embodiment of the present invention is that the comparative embodiment adopts the conventional installation method mentioned above to fix the resistance strain gauge.

[0041] Among them, Table 2 is a comparison table of the on-off states of the sensor 5 in the embodiment of the present invention and the comparative embodiment. It can be seen from the comparison with Table 1 that when a large displacement occurs between the top plate 11 and the bottom plate 12 of the seismic isolation support in the comparative embodiment, that is, when the preset inclination angle of the lead column 4 is 60°, the wire 6 is stretched and dragged by the rubber layer 3 and is completely disconnected from the connection point 51 to produce an open circuit state. In comparison, the inner wire 6 of the seismic isolation support in the embodiment of the present invention has a stretching redundancy in the through hole 21, so that when the rubber layer 3 is deformed and drags and stretches the wire 6, the wire 6 can still be in a good path state with the resistive strain gauge, ensuring the normal transmission of the measurement signal of the resistive strain gauge.

[0042] Embodiment 2

[0043] like Figure 1As shown, the seismic isolation bearing provided by the embodiment of the present invention includes a top plate 11, a bottom plate 12, a lead column 4, a rubber layer 3, a steel plate layer 2 and a sensor 5. Among them, the top plate 11, the bottom plate 12 and the steel plate layer 2 are all circular structures, the steel plate layer 2 is provided with a center hole 22, and the nine layers of steel plate layers 2 and the eight layers of rubber layers 3 are alternately stacked between the top plate 11 and the bottom plate 12. The lead column 4 penetrates the center hole 22 and the rubber layer 3 of each layer of the steel plate layer 2, and the upper and lower ends of the lead column 4 are fixedly connected to the top plate 11 and the bottom plate 12 respectively. Among them, both the top plate 11 and the bottom plate 12 are provided with mounting holes for installation, and the sensor 5 adopts a resistive strain gauge.

[0044] like Figure 2 As shown, the sheet structure of the commonly used resistance strain gauge has two connection points 51 (i.e., welding points) for the lead-out circuit part, and the two connection points 51 are located on the same side of the resistance strain gauge. In the conventional installation method, the other side of the resistance strain gauge away from the connection point 51 is completely bonded and fixed on the surface of the steel plate layer 2 to improve the bonding quality of the resistance strain gauge on the steel plate layer 2, so as to achieve accurate measurement of the deformation of the steel plate layer 2. Accordingly, the connection point 51 of the resistance strain gauge and the wire 6 fixedly connected to the connection point 51 are both buried and pressed in the rubber layer 3.

[0045] like Figure 1 , Figure 3 , Figure 4 as well as Figure 5 As shown, the fifth steel plate layer 2 in the seismic isolation bearing of the embodiment of the present invention is provided with four through holes 21 in the thickness direction, and the four through holes 21 are evenly and symmetrically distributed around the central hole 22 of the steel plate layer 2. The number of sensors 5 is 4, and each sensor 5 is installed on the upper surface of the fifth steel plate layer 2, and the wire 6 connecting the sensor 5 is led out from the rubber layer 3 on the lower surface of the fifth steel plate layer 2 by means of the through hole 21. Among them, the through hole 21 is a strip hole, and the through hole 21 is also used to accommodate the connection point 51 between the resistance strain gauge and the wire 6. This embodiment adopts a strip hole structure to accommodate two connection points 51 on the resistance strain gauge.

[0046] When the resistance strain gauge is installed, the four resistance strain gauges are evenly distributed around the lead core column 4, and the surface on the same side as the connection point 51 of each resistance strain gauge is bonded and fixed to the upper surface of the steel plate layer 2, and the two connection points 51 on the resistance strain gauge are located in the through hole 21 to ensure the flatness and bonding quality of the resistance strain gauge installation. Among them, the part of the wire 6 in the through hole 21 can be set to a spiral or folded shape to retain the tensile redundancy of the deformation of the wire 6.

[0047] like Figure 5 and Figure 7As shown, a wire groove 23 is provided on the lower surface of the steel plate layer 2, one end of the wire groove 23 is connected to the through hole 21, and the other end of the wire groove is open to the outside of the seismic isolation support. Each connected wire 6 is led out of the seismic isolation support along the wire groove 23. Among them, the four wire grooves 23 are distributed along the radial straight line.

[0048] In a preferred embodiment, the wire accommodating groove 23 includes a bending area 231, and the bending area 231 is used to prevent the wire 6 from being pulled out due to external force. Figure 6 As shown, a cross-shaped bending area 231 is formed in the middle of the wire-accommodating groove 23 distributed along the radial direction.

[0049] When the installation is completed, the rubber layer 3 and the steel plate layer 2, the rubber layer 3 and the top plate 11, and the rubber layer 3 and the bottom plate 12 are connected by vulcanization bonding to ensure good shock absorption performance with the steel plate layer 2 after the rubber is cured. Among them, each wire 6 connected to the resistance strain gauge is wired into the wire groove 23 before vulcanization bonding, and the rubber layer 3 is vulcanized to encapsulate the wire 6 in the linear groove and lead it out to the outside of the seismic isolation support.

[0050] When the wire 6 is dragged outside the seismic isolation support, the wire 6 is fixed in the bending area 231 of the linear groove to prevent the wire 6 from being directly pulled out. In addition, when the rubber layer 3 is horizontally displaced and deformed relative to the steel plate layer 2, the wire accommodating groove 23 can retain the wire 6 as a whole in the wire accommodating groove 23, thereby preventing the wire 6 from being stretched and dragged by the rubber layer 3.

[0051] It should be noted that the structure of the bending zone 231 is not limited to the above-mentioned "X"-shaped structure. According to practical applications, those skilled in the art may also set the bending zone 231 to any one of an S-shaped structure, a U-shaped structure or a Z-shaped structure.

[0052] The testing method of the seismic isolation bearing is as follows: the vertical seismic isolation bearing bottom plate 12 is fixed, and a thrust is applied to the top plate 11 in the horizontal direction perpendicular to the lead core column 4 to tilt the lead core column 4 to a preset tilt angle and simultaneously detect the on-off state of the resistive strain gauge.

[0053] Table 2

[0054]

[0055] It should be noted that the preset tilt angle is the angle between the length direction of the lead column 4 and the vertical direction of gravity. The difference between the comparative embodiment and the embodiment of the present invention is that the comparative embodiment adopts the conventional installation method mentioned above to fix the resistance strain gauge.

[0056] Among them, Table 2 is a comparison table of the on-off states of the sensor 5 in the embodiment of the present invention and the comparative embodiment. It can be seen from the comparison of Table 2 that when a large displacement occurs between the top plate 11 and the bottom plate 12 of the seismic isolation support in the comparative embodiment, that is, when the preset inclination angle of the lead column 4 is 60°, the wire 6 is stretched and dragged by the rubber layer 3 to be completely disconnected from the connection point 51 and produce an open circuit state. In comparison, the inner wire 6 of the seismic isolation support in the embodiment of the present invention has a stretching redundancy in the through hole 21 and the bending area 231 of the linear groove can fix the wire 6, so that when the rubber layer 3 is deformed and drags and stretches the wire 6, the wire 6 can still be in a good path state with the resistive strain gauge, ensuring the normal transmission of the measurement signal of the resistive strain gauge.

[0057] Embodiment 3

[0058] like Figure 1 and Figure 8 As shown, an embodiment of the present invention provides an earthquake monitoring system, which includes the seismic isolation support of embodiment 1 or embodiment 2 and a signal processing device electrically connected to the seismic isolation support. After the signal processing device is connected to the wire 6 on the seismic isolation support, the signal processing device receives and processes the signal from the sensor 5 installed in the seismic isolation support, and transmits the data obtained after the signal processing to the remote monitoring center for monitoring and analysis. Since the above-mentioned seismic isolation support can still maintain good signal transmission of the sensor 5 after a large deformation, the seismic isolation support is installed in the transmission station and the substation to meet the seismic monitoring of power equipment.

[0059] like Figure 8 As shown, the signal processing device of the embodiment of the present invention comprises a main control module, a signal conditioning module, a communication module, a storage module and a power supply module, wherein the signal conditioning module, the communication module and the power supply module are all electrically connected to the main control module.

[0060] The main control module adopts the combined architecture design of FPGA (field programmable gate array) and MCU (microcontroller) to realize the synchronous acquisition and processing of the signals of the four sensors 5 (resistance strain gauges) on the seismic isolation support. The CPU model in the MCU adopts the domestic Loongson LS2K2100, and the FPGA model adopts the domestic Unisplendour Tongchuang Logos-2 series PG2L100H.

[0061] The signal conditioning module of the embodiment of the present invention is used to filter the collected signal of the sensor 5. The signal conditioning module uses at least one of an AC coupling circuit, a low-pass filter circuit, an operational amplifier circuit or a voltage follower circuit.

[0062] AC coupling circuits can effectively reduce interference to DC signals, improve signal stability and accuracy, and thus improve the signal-to-noise ratio. This can better retain signal information and reduce the impact of noise on the signal. Low-pass filter circuits can filter out high-frequency noise and retain low-frequency signals, thereby improving the signal-to-noise ratio. By removing noise interference, the signal can be presented more clearly. Operational amplifier circuits can provide high gain and high input impedance, which helps to amplify signals and reduce the impact of noise. Operational amplification can improve the sensitivity and accuracy of signals, thereby improving the signal-to-noise ratio. Voltage follower circuits can make the output signal follow the changes in the input signal, maintain a certain phase and amplitude relationship, help stabilize signal transmission and reduce amplitude distortion, and improve signal quality and signal-to-noise ratio.

[0063] The signal conditioning circuit needs to suppress noise and interference within a certain frequency range. The low-pass filter circuit in this embodiment adopts a second-order Butterworth filter circuit to improve the signal-to-noise ratio of the circuit.

[0064] The communication module of the embodiment of the present invention wirelessly transmits data information to a remote monitoring center or a cloud terminal.

[0065] The communication module uses a combination of 4G or 5G network and wireless network to transmit the collected and processed data information from the remote monitoring center to the cloud terminal.

[0066] The power supply module of the embodiment of the present invention includes a storage battery and a photovoltaic panel. The storage battery and the photovoltaic panel ensure the stable operation of the signal processing device when the city power is cut off.

[0067] The signal processing device of the embodiment of the present invention further includes a data storage module electrically connected to the main control module, and the data storage module is used to store the data information obtained by the collection and processing. The data storage module uses the storage chip of Unigroup Guowei SCB13H4G160AF-11MI and GigaDevice GD25Q127CSIG.

[0068] The data storage module also includes a remote cloud storage service, which uploads the collected and processed data information to the cloud storage service terminal for storage through the communication module, facilitating the integration of storage resources, thereby realizing unified scheduling and monitoring of data, and greatly improving the efficiency of data use.

[0069] The earthquake monitoring system conducts earthquake monitoring on power equipment and can evaluate the status of power equipment in substations after an earthquake, thereby facilitating the repair efficiency of substations after an earthquake. The system has low deployment costs, and subsequent system updates, maintenance and upgrades are simple, making it easy to promote and apply on a large scale.
