In the description of this invention, unless otherwise stated, "a plurality of" means two or more.
[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0039] The following is for reference. Figures 1-6 An anti-seismic device 100 for a large aqueduct 200 according to an embodiment of the present invention is described.
[0040] Reference Figure 6 According to the embodiments of the present invention, the anti-seismic device 100 for a large aqueduct 200 includes a pier 210 and a body 220. A support 240 is provided between the pier 210 and the body 220. The support 240 can transfer the load of the body 220 to the pier 210, which is beneficial to improving the structural stability and safety of the large aqueduct 200.
[0041] Combination Figure 1 and Figure 6 The seismic device 100 includes a first connecting seat 110, a second connecting seat 120, and a shock absorber 130. The first connecting seat 110 is disposed on the groove body 220, the second connecting seat 120 is disposed on the groove pier 210, and the first connecting seat 110 and the second connecting seat 120 are spaced apart in a first direction. The shock absorber 130 is connected between the first connecting seat 110 and the second connecting seat 120.
[0042] It should be noted that "first direction" can be understood as the length direction of the large aqueduct 200. For a specific direction diagram, please refer to [reference needed]. Figures 1 to 6 As shown.
[0043] For example, the first connecting seat 110 is connected to the trough body 220, and the second connecting seat 120 is connected to the trough pier 210. By making the first connecting seat 110 and the second connecting seat 120 spaced apart in the first direction, the shock absorber 130 can be arranged between the first connecting seat 110 and the second connecting seat 120. When an earthquake occurs, the shock absorber 130 can consume the energy of the seismic wave, which is beneficial to improving the stability of the large aqueduct 200, reducing the risk of damage to the large aqueduct 200, and extending the service life of the large aqueduct 200.
[0044] The shock absorber 130 can slide relative to the first connecting seat 110 and the second connecting seat 120 along a second direction; wherein the first direction and the second direction are both horizontal, and the first direction and the second direction are perpendicular to each other.
[0045] It should be noted that "second direction" can be understood as the width direction of the large aqueduct 200. A detailed diagram of the direction can be found in [reference needed]. Figures 1 to 6 As shown.
[0046] By allowing the shock absorber 130 to slide relative to the first connecting seat 110 and the second connecting seat 120 in a sliding engagement, under normal use, the shock absorber 130 can slide relative to the first connecting seat 110 and the second connecting seat 120 in a second direction. Considering that the support 240 may deform due to temperature, allowing the shock absorber 130 to slide relative to the first connecting seat 110 and the second connecting seat 120 in a second direction can adapt to the deformation direction of the support 240. Furthermore, under minor earthquake conditions, the support 240 tends to deform in a second direction. By making the movement direction of the shock absorber 130 relative to the first connecting seat 110 and the second connecting seat 120 the same as the deformation direction of the support 240, the shock absorber 130 can prevent the deformation of the support 240 from being hindered. At the same time, the shock absorber 130 can share the force with the support 240 in the first direction, thereby further reducing the seismic force on the support 240 and helping to further reduce the risk of damage to the support 240.
[0047] In the event of a major earthquake, the damper 130 can yield and dissipate energy to absorb the seismic energy transmitted to the support 240, which helps to reduce the seismic energy transmitted to the pier 210. Furthermore, after yielding, the damper 130 can still maintain a certain yield force to limit the trough body 220 and prevent the trough body 220 from colliding with the pier 210. This reduces the risk of the large aqueduct 200 falling off during a major earthquake and helps to improve the structural stability and safety of the large aqueduct 200.
[0048] In related technologies, the supports are the weak points of large aqueducts. When an earthquake occurs, the supports are easily damaged, which can cause the aqueduct body and the piers to collide, resulting in poor structural safety of large aqueducts.
[0049] This application provides a first connecting seat 110 and a second connecting seat 120 on the aqueduct body 220 and the aqueduct pier 210, respectively, to facilitate the arrangement of the shock absorber 130. By allowing the shock absorber 130 to slide relative to the first connecting seat 110 and the second connecting seat 120 in a second direction, it coordinates with the deformation direction of the support 240. In the case of minor earthquakes, the movement direction of the shock absorber 130 is the same as the deformation direction of the support 240 to prevent the shock absorber 130 from hindering the deformation of the support 240. At the same time, the shock absorber 130 can share the force with the support 240 in the first direction to reduce the seismic force on the support 240 and reduce the risk of the support 240 being damaged. In the case of major earthquakes, the shock absorber 130 can yield and dissipate energy to reduce the risk of collision between the aqueduct pier 210 and the aqueduct body 220, which is beneficial to improving the structural stability and safety of the large aqueduct 200.
[0050] Alternatively, the shock absorber 130 can be configured as a high-tonnage friction damper.
[0051] Combination Figure 1 and Figure 2 In some embodiments of the present invention, the shock absorber 130 includes: a shock absorber body 131, a first mounting base 132 and a second mounting base 133. The first mounting base 132 is connected to a first side of the shock absorber body 131 in a first direction and is slidably mounted on a first connecting base 110 in a second direction. The second mounting base 133 is connected to a second side of the shock absorber body 131 in a first direction and is slidably mounted on a second connecting base 120 in a second direction.
[0052] It should be noted that "the first side of the shock absorber body 131 in the first direction" can be understood as the side of the shock absorber body 131 close to the first connecting seat 110 in the first direction, and "the second side of the shock absorber body 131 in the first direction" can be understood as the side of the shock absorber body 131 close to the second connecting seat 120 in the first direction.
[0053] For example, the shock absorber body 131 has a first mounting seat 132 and a second mounting seat 133 on both sides of the first direction, extending in a direction away from the shock absorber body 131. The first mounting seat 132 is slidably engaged with the first connecting seat 110, and the second mounting seat 133 is slidably engaged with the second connecting seat 120, so that the shock absorber 130 can slide relative to the first connecting seat 110 and the second connecting seat 120 in a second direction. Under small vibration conditions, the first mounting seat 132 and the second mounting seat 133 slide relative to the first connecting seat 110 and the second connecting seat 120. The second direction slides relative to the first connecting seat 110 and the second connecting seat 120 respectively to prevent the shock absorber 130 from hindering the deformation of the support 240. At the same time, the shock absorber 130 and the support 240 are subjected to force together in the first direction to protect the support 240 and reduce the risk of the support 240 being damaged. Under the condition of a large earthquake, the shock absorber body 131 yields and dissipates energy, and the shock absorber body 131 still maintains a certain yield force after yielding to limit the groove body 220 and prevent the groove body 220 from colliding with the groove pier 210.
[0054] By providing a first mounting base 132 and a second mounting base 133 on the shock absorber body 131, the assembly of the shock absorber 130 with the first connecting base 110 and the second connecting base 120 can be facilitated, which helps to improve the assembly efficiency of the anti-seismic device 100.
[0055] Combination Figures 1 to 4 In some embodiments of the present invention, the first connecting seat 110 is provided with a first mounting groove 111 that is recessed to the first side and open to the second side, and the first mounting groove 111 is used to install the first mounting seat 132.
[0056] For example, the first connecting seat 110 has a first mounting groove 111 on the side surface opposite to the shock absorber 130 in the first direction. The first mounting groove 111 is recessed in the direction away from the shock absorber 130 along the first direction, and the side of the first mounting groove 111 opposite to the shock absorber 130 is open. The first mounting seat 132 extends into the first mounting groove 111 to realize the connection and cooperation between the shock absorber 130 and the first connecting seat 110. The first mounting groove 111 extends in the second direction so that the first mounting seat 132 can slide in the first mounting groove 111.
[0057] Combination Figure 1 , Figure 2 and Figure 5 The second connecting seat 120 is provided with a second mounting groove 121 that is recessed to the second side and open to the first side. The second mounting groove 121 is used to install the second mounting seat 133, and the first mounting groove 111 and the second mounting groove 121 are arranged opposite to each other in the first direction.
[0058] For example, the second connecting seat 120 has a second mounting groove 121 on the side surface opposite to the shock absorber 130 in the first direction. The second mounting groove 121 is recessed in the direction away from the shock absorber 130 along the first direction, and the first mounting groove 111 is open on the side opposite to the shock absorber 130. The second mounting seat 133 extends into the second mounting groove 121 to realize the connection and cooperation between the shock absorber 130 and the second connecting seat 120. The second mounting groove 121 extends in the second direction so that the second mounting seat 133 can slide in the second mounting groove 121 in the second direction.
[0059] Since the first connecting seat 110 and the second connecting seat 120 cooperate with the groove body 220 and the groove pier 210 respectively, the shock absorber 130 is arranged between the groove pier 210 and the groove body 220, so that the shock absorber 130 can play the role of shock absorption and energy dissipation between the groove pier 210 and the groove body 220.
[0060] In some embodiments of the present invention, the inner wall surface of the first mounting groove 111 is provided with a first wear-resistant coating, which can be formed as a polytetrafluoroethylene coating to reduce the friction between the inner wall surface of the first mounting groove 111 and the first mounting seat 132, improve the sliding convenience of the first mounting seat 132 in the first mounting groove 111, and help reduce the wear of the first mounting seat 132 and the first mounting groove 111, thereby helping to improve the service life of the anti-vibration device 100.
[0061] The inner wall of the second mounting groove 121 is provided with a second wear-resistant coating, which can be formed as a polytetrafluoroethylene coating to reduce the friction between the inner wall of the second mounting groove 121 and the second mounting seat 133, improve the sliding convenience of the second mounting seat 133 in the second mounting groove 121, and help reduce the wear of the second mounting seat 133 and the second mounting groove 121, thereby helping to improve the service life of the anti-vibration device 100.
[0062] Optionally, a first wear-resistant coating may be provided separately on the inner wall surface of the first mounting groove 111, or a second wear-resistant coating may be provided separately on the inner wall surface of the second mounting groove 121, to reduce the production cost of the shock absorber 100; or, while the inner wall surface of the first mounting groove 111 is provided with a first wear-resistant coating, the inner wall surface of the second mounting groove 121 may be provided with a second wear-resistant coating, to improve the sliding convenience of the shock absorber 130 relative to the first connecting seat 110 and the second connecting seat 120, and to further improve the service life of the shock absorber 100.
[0063] Combination Figures 1 to 4 In some embodiments of the present invention, the first mounting groove 111 is provided with a first sliding groove 1111 recessed in the vertical direction and extending in the first direction, and the first mounting base 132 is provided with a first slider 1321, which slides in cooperation with the first sliding groove 1111.
[0064] It should be noted that "vertical direction" can be understood as the height direction of the large aqueduct 200, which is perpendicular to the first and second directions. A detailed directional diagram can be found in [reference needed]. Figures 1 to 6 As shown.
[0065] For example, the first slider 1321 is disposed at one end of the first mounting base 132 away from the shock absorber body 131 in the first direction, and the first slider 1321 protrudes vertically from the first mounting base 132. The first mounting groove 111 is provided with a first sliding groove 1111 on the side away from its open end in the first direction. In the projection in the first direction, the orthographic projection plane of the first mounting groove 111 falls within the orthographic projection range of the first sliding groove 1111. That is, the first sliding groove 1111 protrudes vertically from the first mounting groove 111. The first slider 1321 is embedded in the first sliding groove 1111 and can slide in the first sliding groove 1111 along the second direction. At the same time, the inner groove wall of the first sliding groove 1111 can abut against the first slider 1321 to limit the first slider 1321 in the first direction and the vertical direction, preventing the first slider 1321 from coming out of the first sliding groove 1111, which is beneficial to improving the reliability of the fit between the shock absorber 130 and the first connecting base 110.
[0066] Combination Figures 1 to 5The second mounting groove 121 is provided with a second sliding groove 1211 that is recessed in the vertical direction and extends in the first direction, and the second mounting base 133 is provided with a second slider 1331, which slides in cooperation with the second sliding groove 1211.
[0067] For example, the second slider 1331 is disposed at one end of the second mounting base 133 away from the shock absorber body 131 in the first direction, and the second slider 1331 protrudes from the second mounting base 133 in the vertical direction. The second mounting groove 121 is provided with a second sliding groove 1211 on the side away from its open end in the first direction. In the projection in the first direction, the orthographic projection plane of the second mounting groove 121 falls within the orthographic projection range of the second sliding groove 1211. That is, the second sliding groove 1211 protrudes from the second mounting groove 121 in the vertical direction. The second slider 1331 is embedded in the first sliding groove 1111 and can slide in the second sliding groove 1211 in the second direction. At the same time, the inner groove wall of the second sliding groove 1211 can abut against the second sliding groove 1211 to limit the second slider 1331 in the first direction and the vertical direction, preventing the second slider 1331 from coming out of the second sliding groove 1211, which is beneficial to improving the reliability of the fit between the shock absorber 130 and the second connecting base 120.
[0068] It should be noted that when the first mounting groove 111 is provided with the first wear-resistant coating, the first sliding groove 1111 is also provided with the first wear-resistant coating, and when the second mounting groove 121 is provided with the second wear-resistant coating, the second sliding groove 1211 is also provided with the second wear-resistant coating.
[0069] In some embodiments of the present invention, the outer wall surface of the first slider 1321 is provided with a third wear-resistant coating, which can be formed as a polytetrafluoroethylene coating to reduce the friction between the first slider 1321 and the first slide groove 1111, improve the sliding convenience of the first slider 1321 in the first slide groove 1111, and help reduce the wear of the first slider 1321 and the first slide groove 1111, thereby helping to improve the service life of the anti-vibration device 100.
[0070] The outer wall surface of the second slider 1331 is provided with a fourth wear-resistant coating, which can be formed as a polytetrafluoroethylene coating to reduce the friction between the second slider 1331 and the second slide groove 1211. This helps to improve the sliding convenience of the second slider 1331 in the second slide groove 1211 and also helps to reduce the wear between the second slider 1331 and the second slide groove 1211, thereby helping to improve the service life of the anti-vibration device 100.
[0071] Optionally, a third wear-resistant coating may be provided separately on the outer wall surface of the first slider 1321, or a fourth wear-resistant coating may be provided separately on the outer wall surface of the second slider 1331, to reduce the production cost of the shock absorber 100; or the outer wall surface of the first slider 1321 may be provided with a third wear-resistant coating while the outer wall surface of the second slider 1331 is provided with a fourth wear-resistant coating, to improve the sliding convenience of the shock absorber 130 relative to the first connecting seat 110 and the second connecting seat 120, and to further improve the service life of the shock absorber 100.
[0072] Preferably, the first mounting groove 111 and the first sliding groove 1111 are provided with a first wear-resistant coating, the first slider 1321 is provided with a third wear-resistant coating, the second mounting groove 121 and the second sliding groove 1211 are provided with a second wear-resistant coating, and the second slider 1331 is provided with a fourth wear-resistant coating, so as to further improve the friction between the shock absorber 130 and the first connecting seat 110 and the second connecting seat 120, which is conducive to further improving the sliding convenience of the shock absorber 130 relative to the first connecting seat 110 and the second connecting seat 120, and at the same time, it is conducive to further improving the service life of the anti-vibration device 100.
[0073] The materials used to form the first connecting seat 110, the second connecting seat 120, the first slider 1321, and the second slider 1331 can all be steel to ensure the structural strength of the seismic device 100.
[0074] Combination Figure 1 and Figure 6 In some embodiments of the present invention, a first connecting seat 110 is provided at the bottom of the groove body 220, and a first connecting part 112 is provided at the top of the first connecting seat 110, the first connecting part 112 being used to connect with the groove body 220.
[0075] For example, a first connecting part 112 may be provided on the top wall of the first connecting seat 110. The first connecting part 112 may be formed as a threaded hole. The first connecting part 112 may be fixedly connected to the bottom of the groove body 220 by a high-strength bolt, thereby realizing the connection between the first connecting seat 110 and the bottom of the groove body 220. This is beneficial to improving the connection strength between the first connecting seat 110 and the groove body 220, and also beneficial to improving the ease of disassembly and assembly of the first connecting seat 110 and the groove body 220.
[0076] Combination Figure 1 and Figure 6 The second connecting seat 120 has a second connecting part 122 on the side surface opposite to the first connecting seat 110 in the first direction. The second connecting part 122 is used to connect with the trough block 210.
[0077] For example, the second connecting seat 120 is provided with a second connecting part 122 on the side surface opposite to the groove block 210 in the first direction. The second connecting part 122 can be formed as a threaded hole, and the second connecting part 122 can be fixedly connected to the side wall of the groove block 210 by a high-strength bolt, thereby realizing the connection between the second connecting seat 120 and the groove block 210. This is beneficial to improving the connection strength between the first connecting seat 110 and the groove block 210, and at the same time, it is beneficial to improve the ease of disassembly and assembly of the second connecting seat 120 and the groove block 210.
[0078] Optionally, while the top of the first connecting seat 110 is provided with a first connecting part 112, the second connecting seat 120 is provided with a second connecting part 122 on the side surface of the second connecting seat 120 facing away from the first connecting seat 110 in the first direction, so as to realize the connection between the anti-seismic device 100 and the trough pier 210 and the trough body 220 respectively.
[0079] The first connecting part 112 and the second connecting part 122 can be provided in multiple ways to further improve the connection reliability between the first connecting seat 110 and the groove body 220 and the connection reliability between the second connecting seat 120 and the groove support 210. It is understood that the number of the first connecting part 112 and the second connecting part 122 can be determined according to the actual assembly requirements, and no specific limitation is made here.
[0080] By providing a first connecting part 112 and a second connecting part 122 on the first connecting seat 110 and the second connecting seat 120 respectively, the seismic device 100 can be installed on the large aqueduct 200 that has been put into actual use, thereby improving the seismic resistance of the large aqueduct 200 that has been put into actual use. The seismic device 100 can also be directly installed during the construction process of the large aqueduct 200 to improve the seismic resistance of the large aqueduct 200, thereby expanding the applicability of the seismic device 100.
[0081] like Figure 5 As shown, in some embodiments of the present invention, the first connecting seat 110 is provided with a first weight reduction groove 113.
[0082] For example, the first connecting seat 110 may have a first weight-reducing groove 113 on at least one side surface in the second direction. The first weight-reducing groove 113 is recessed from one side surface of the first connecting seat 110 in the second direction in a direction away from that side surface. By providing the first weight-reducing groove 113, it is beneficial to reduce the weight of the first connecting seat 110, thereby facilitating the lightweight design of the anti-vibration device 100, making the assembly of the anti-vibration device 100 easier, and also helping to reduce the material cost of the anti-vibration device 100.
[0083] Combination Figure 3 and Figure 4 The second connecting seat 120 is provided with a second weight reduction groove 123.
[0084] For example, the second connecting seat 120 is provided with a second weight reduction groove 123 on one side surface in the second direction. The second weight reduction groove 123 is recessed from one side surface of the second connecting seat 120 in the second direction in a direction away from the side surface. By providing the second weight reduction groove 123, it is beneficial to reduce the weight of the second connecting seat 120, thereby facilitating the lightweight design of the shock-absorbing device 100, making the assembly of the shock-absorbing device 100 easier, and also helping to reduce the material cost of the shock-absorbing device 100.
[0085] Optionally, while the first connecting seat 110 is provided with a first weight-reducing groove 113, the second connecting seat 120 may be provided with a second weight-reducing groove 123 to reduce the weight of the first connecting seat 110 and the second connecting seat 120 respectively, thereby helping to further reduce the weight of the seismic device 100, facilitating the assembly of the seismic device 100, and also helping to further reduce the material cost of the seismic device 100.
[0086] It is understandable that the specific arrangement of the first weight-reducing groove 113 and the second weight-reducing groove 123 can be determined according to actual production requirements, and no specific limitation is made here, as long as the rigidity of the first connecting seat 110 and the second connecting seat 120 can meet the installation requirements.
[0087] Reference Figure 6 The large aqueduct 200 according to an embodiment of the present invention includes the above-described anti-seismic device 100.
[0088] Because the large aqueduct 200 is equipped with the aforementioned seismic device 100, the arrangement of the shock absorber 130 is facilitated by setting the first connecting seat 110 and the second connecting seat 120 on the aqueduct body 220 and the abutment 210, respectively. The shock absorber 130 can slide relative to the first connecting seat 110 and the second connecting seat 120 in a second direction to coordinate with the deformation direction of the support 240. At the same time, under small earthquake conditions, the movement direction of the shock absorber 130 is the same as the deformation direction of the support 240 to prevent the shock absorber 130 from hindering the deformation of the support 240. The shock absorber 130 can share the force with the support 240 in the first direction to reduce the seismic force on the support 240 and reduce the risk of the support 240 being damaged. Under large earthquake conditions, the shock absorber 130 can yield and dissipate energy to reduce the risk of collision between the abutment 210 and the aqueduct body 220, which is beneficial to improving the structural stability and safety of the large aqueduct 200.
[0089] Combination Figures 1 to 6In some embodiments of the present invention, the large aqueduct 200 further includes a monitoring component 230, which includes an acceleration sensor 231, a force sensor 232, and a wireless transmission device 233. The acceleration sensor 231 is disposed on the anti-vibration device 100 and can measure the acceleration time history of the anti-vibration device 100. Since the anti-vibration device 100 is connected to the large aqueduct 200 and the large aqueduct 200 and the anti-vibration device 100 have the same acceleration time history, the acceleration sensor 231 can measure the acceleration time history of the large aqueduct 200. The acceleration sensor 231 is electrically connected to the wireless transmission device 233, which can collect the measurement data of the acceleration sensor 231 and remotely transmit the measurement data of the acceleration sensor. The transmitted data can be used for modal analysis to monitor the health status of the large aqueduct 200.
[0090] Force sensor 232 is installed on the seismic device 100. Force sensor 232 can measure the reaction force of shock absorber 130 when an earthquake occurs. Force sensor 232 is electrically connected to wireless transmission device 233. Wireless transmission device 233 can also collect the measurement data of force sensor 232 and transmit the measurement data of force sensor 232 remotely. Seismic inversion is performed based on the measurement data of force sensor 232 to evaluate the structural damage state of large aqueduct 200 after earthquake and to estimate whether large aqueduct 200 is damaged, so as to realize the seismic analysis of large aqueduct 200, which can also be understood as realizing the post-earthquake assessment of large aqueduct 200.
[0091] Therefore, by setting up the monitoring component 230, it is convenient to monitor the health status of the large aqueduct 200 in real time and to conduct post-earthquake assessment of the large aqueduct 200.
[0092] Combination Figures 1 to 6 In some embodiments of the present invention, the acceleration sensor 231 includes: a first acceleration sensor 2311, which is disposed on the first connecting seat 110 and is used to acquire the acceleration time history of the first connecting seat 110. Since the first connecting seat 110 is connected to the groove body 220, the acceleration time history of the first connecting seat 110 acquired by the first acceleration sensor 2311 is equivalent to the acceleration time history of the groove body 220.
[0093] The acceleration sensor 231 also includes a second acceleration sensor 2312, which is disposed on the second connecting seat 120 and is used to acquire the acceleration time history of the second connecting seat 120. Since the second connecting seat 120 is connected to the trough pier 210, the acceleration time history of the second connecting seat 120 acquired by the second acceleration sensor 2312 is equivalent to the acceleration time history of the trough pier 210.
[0094] By measuring the acceleration time histories of the trough body 220 and the trough pier 210 respectively, and performing modal analysis on the obtained data, the state of the large aqueduct 200 can be inferred, thereby realizing the seismic analysis of the large aqueduct 200.
[0095] In some embodiments of the present invention, the first acceleration sensor 2311 can be arranged in the first weight reduction groove 113, without the need to design a separate installation space for the first acceleration sensor 2311 on the first connecting seat 110, which is beneficial to improve the space utilization on the first connecting seat 110 and facilitates the setting of the first acceleration sensor 2311.
[0096] The second acceleration sensor 2312 can be arranged in the second weight reduction slot 123, eliminating the need to design separate installation space for the second acceleration sensor 2312 on the second connecting seat 120. This improves the space utilization of the second connecting seat 120 and facilitates the installation of the second acceleration sensor 2312.
[0097] The wireless transmission device 233 and the force sensor 232 can be installed in the first weight reduction groove 113 or the second weight reduction groove 123. The installation position of the wireless transmission device 233 and the force sensor 232 is not specifically limited here, as long as it is convenient for the wireless transmission device 233 to be electrically connected to the force sensor 232 and the acceleration sensor 231 respectively.
