[0039] Reference below Figure 1-Figure 6 A seismic resistant device 100 for a large aqueduct 200 according to an embodiment of the present invention is described.

[0040] Reference Figure 6 According to the earthquake-resistant device 100 for a large aqueduct 200 described in an embodiment of the present invention, the large aqueduct 200 has a trough pier 210 and a trough body 220, and a support 240 is provided between the trough pier 210 and the trough body 220. The support 240 can transfer the load of the trough body 220 to the trough 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 anti-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 arranged on the groove body 220, the second connecting seat 120 is arranged on the groove pier 210, and the first connecting seat 110 and the second connecting seat 120 are spaced apart in the first direction, and the shock absorber 130 is connected between the first connecting seat 110 and the second connecting seat 120.

[0042] It should be noted that the “first direction” can be understood as the length direction of the large aqueduct 200. For specific directions, please refer to Figures 1 to 6 shown.

[0043] Exemplarily, 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, and the first connecting seat 110 and the second connecting seat 120 are spaced apart in the first direction so that 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 the second direction; wherein the first direction and the second direction are both horizontal directions, and the first direction and the second direction are perpendicular to each other.

[0045] It should be noted that the “second direction” can be understood as the width direction of the large aqueduct 200. For specific directions, please refer to Figures 1 to 6 shown.

[0046] By making the shock absorber 130 slideably cooperate with the first connecting seat 110 and the second connecting seat 120, under normal use, the shock absorber 130 can slide relative to the first connecting seat 110 and the second connecting seat 120 along the second direction. Considering that the support 240 may be deformed due to the influence of temperature, making the shock absorber 130 slide relative to the first connecting seat 110 and the second connecting seat 120 along the second direction can adapt to the deformation direction of the support 240; and in the case of a small earthquake, the support 240 has a tendency to deform along the second direction. By making the moving 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 is prevented from hindering the deformation of the support 240. At the same time, the shock absorber 130 can be subjected to force together with the support 240 in the first direction to further reduce the seismic force on the support 240, which is conducive to further reducing the risk of damage to the support 240.

[0047] In the event of a major earthquake, the shock absorber 130 can yield and dissipate energy to absorb the seismic energy transmitted to the support 240, which is beneficial to reducing the seismic energy transmitted to the trough pier 210, and the shock absorber 130 can still maintain a certain yield force after yielding to limit the trough body 220 and prevent the trough body 220 from colliding with the trough pier 210, thereby reducing the risk of beam falling of the large-scale aqueduct 200 in the event of a major earthquake, which is beneficial to improving the structural stability and safety of the large-scale aqueduct 200.

[0048] In the related art, the support is the weak part of the large aqueduct. When an earthquake occurs, the support is easily damaged, which causes the trough body and the trough pier to collide easily, resulting in poor structural safety of the large aqueduct.

[0049] The present application arranges the first connecting seat 110 and the second connecting seat 120 on the trough body 220 and the trough pier 210 respectively to facilitate the arrangement of the shock absorber 130, and enables the shock absorber 130 to slide along the second direction relative to the first connecting seat 110 and the second connecting seat 120 to coordinate with the deformation direction of the support 240. At the same time, in the case of a small earthquake, 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 be subjected to force together with the support 240 in the first direction to reduce the seismic force on the support 240 and reduce the risk of damage to the support 240. In the case of a large earthquake, the shock absorber 130 can yield and dissipate energy to reduce the risk of collision between the trough pier 210 and the trough body 220, which is beneficial to improving the structural stability and safety of the large-scale aqueduct 200.

[0050] Alternatively, the shock absorber 130 may 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 seat 132 and a second mounting seat 133, the first mounting seat 132 is connected to the first side of the shock absorber body 131 in the first direction, and the first mounting seat 132 is slidably mounted on the first connecting seat 110 along the second direction, the second mounting seat 133 is connected to the second side of the shock absorber body 131 in the first direction, and the second mounting seat 133 is slidably mounted on the second connecting seat 120 along the 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] Exemplarily, the shock absorber body 131 is provided with a first mounting seat 132 and a second mounting seat 133 extending in the first direction away from the shock absorber body 131 on both sides in the first direction, and the first mounting seat 132 is slidably matched with the first connecting seat 110, and the second mounting seat 133 is slidably matched 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 the second direction. In the case of a small earthquake, the first mounting seat 132 and the second mounting seat 133 are slidably matched with 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 jointly subjected to force in the first direction to protect the support 240 and reduce the risk of damage to the support 240. In the event of a large earthquake, the shock absorber body 131 yields and consumes energy, and the shock absorber body 131 still maintains a certain yield force after yielding to limit the trough body 220 and prevent the trough body 220 from colliding with the trough pier 210.

[0054] By arranging the first mounting seat 132 and the second mounting seat 133 on the shock absorber body 131 , it is convenient to assemble the shock absorber 130 with the first connecting seat 110 and the second connecting seat 120 , which is beneficial to improve the assembly efficiency of the anti-seismic device 100 .

[0059] Since the first connecting seat 110 and the second connecting seat 120 cooperate with the trough body 220 and the trough pier 210 respectively, the shock absorber 130 is arranged between the trough pier 210 and the trough body 220, so that the shock absorber 130 can play a shock-absorbing and energy-consuming effect between the trough pier 210 and the trough body 220.

[0078] Optionally, a first connection portion 112 is provided on the top of the first connection seat 110, and a second connection portion 122 is provided on a side surface of the second connection seat 120 away from the first connection seat 110 in the first direction, so as to realize the connection between the seismic anti-seismic device 100 and the trough pier 210 and the trough body 220 respectively.

[0079] Among them, the first connecting part 112 and the second connecting part 122 can be provided in plurality 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 pier 210. It can be understood that the number of the first connecting part 112 and the second connecting part 122 can be determined according to actual assembly requirements and is not specifically limited here.

The earthquake-resistant device 100 can also be directly installed during the construction of the large-scale aqueduct 200 to improve the earthquake-resistant capacity of the large-scale aqueduct 200, thereby improving the scope of application of the earthquake-resistant 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-reducing groove 113 .

[0082] Exemplarily, a first weight-reducing groove 113 may be provided on the surface of at least one side of the first connecting seat 110 in the second direction. The first weight-reducing groove 113 is recessed from the side surface of the first connecting seat 110 in the second direction along the second direction toward a direction away from the side surface. By providing the first weight-reducing groove 113, it is helpful to reduce the weight of the first connecting seat 110, and further helps to realize the lightweight design of the anti-seismic device 100, facilitate the assembly of the anti-seismic device 100, and help to reduce the material cost of the anti-seismic device 100.

[0083] Combination Figure 3 and Figure 4 The second connecting seat 120 is provided with a second weight-reducing groove 123 .

[0084] Exemplarily, a second weight-reducing groove 123 is provided on one side surface of the second connecting seat 120 in the second direction. The second weight-reducing groove 123 is recessed from one side surface of the second connecting seat 120 in the second direction along the second direction toward a direction away from the side surface. By providing the second weight-reducing groove 123, it is helpful to reduce the weight of the second connecting seat 120, and further helps to realize a lightweight design of the anti-seismic device 100, facilitates the assembly of the anti-seismic device 100, and helps to reduce the material cost of the anti-seismic 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 facilitating further reducing the weight of the anti-seismic device 100, facilitating the assembly of the anti-seismic device 100, and facilitating further reducing the material cost of the anti-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 is not specifically limited 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-scale aqueduct 200 according to the embodiment of the present invention includes the above-mentioned earthquake-resistant device 100.

[0088] Since the large-scale aqueduct 200 is provided with the above-mentioned earthquake-resistant device 100, the first connecting seat 110 and the second connecting seat 120 are respectively provided on the trough body 220 and the trough pier 210 to facilitate the arrangement of the shock absorber 130. The shock absorber 130 is made to slide relative to the first connecting seat 110 and the second connecting seat 120 along the second direction to coordinate with the deformation direction of the support 240. Meanwhile, in the case of a small earthquake, the moving 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 be subjected to force together 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 a large earthquake, the shock absorber 130 can yield and dissipate energy to reduce the risk of collision between the trough pier 210 and the trough body 220, which is beneficial to improving the structural stability and safety of the large-scale aqueduct 200.

[0089] Combination Figures 1 to 6In some embodiments of the present invention, the large-scale 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 arranged on the anti-seismic device 100, and the acceleration sensor 231 can measure the acceleration time course of the anti-seismic device 100. Since the anti-seismic device 100 is connected to the large-scale aqueduct 200, the large-scale aqueduct 200 and the anti-seismic device 100 have the same acceleration time course, so the acceleration sensor 231 can measure the acceleration time course of the large-scale aqueduct 200. The acceleration sensor 231 is electrically connected to the wireless transmission device 233, and the wireless transmission device 233 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-scale aqueduct 200.

[0090] The force sensor 232 is arranged on the seismic resistant device 100. The force sensor 232 can measure the reaction force of the shock absorber 130 when an earthquake occurs, and the force sensor 232 is electrically connected to the wireless transmission device 233. The wireless transmission device 233 can also collect the measurement data of the force sensor 232 and transmit the measurement data of the force sensor 232 remotely. Seismic inversion is performed based on the measurement data of the force sensor 232 to evaluate the structural damage state of the large aqueduct 200 after the earthquake, and to infer whether the large aqueduct 200 is destroyed, so as to realize the seismic analysis of the large aqueduct 200, which can also be understood as realizing the post-earthquake evaluation of the large aqueduct 200.

[0091] Therefore, by providing the monitoring component 230 , it is convenient to monitor the health status of the large-scale aqueduct 200 in real time and to conduct a post-earthquake evaluation of the large-scale 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 arranged on the first connecting seat 110 and is used to obtain the acceleration time series of the first connecting seat 110. Since the first connecting seat 110 is connected to the slot body 220, the acceleration time series of the first connecting seat 110 obtained by the first acceleration sensor 2311 is equivalent to obtaining the acceleration time series of the slot body 220.

[0093] The acceleration sensor 231 also includes a second acceleration sensor 2312, which is arranged on the second connecting socket 120 and is used to obtain the acceleration time series of the second connecting socket 120. Since the second connecting socket 120 is connected to the groove pier 210, the acceleration time series of the second connecting socket 120 obtained by the second acceleration sensor 2312 is equivalent to the acceleration time series of the groove pier 210.

[0094] By measuring the acceleration time histories of the channel body 220 and the channel pier 210 respectively and performing modal analysis on the acquired data, the state of the large-scale aqueduct 200 can be inferred, thereby realizing the seismic analysis of the large-scale 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, and there is no need to design an installation space for the first acceleration sensor 2311 on the first connecting seat 110 separately, which is beneficial to improving the space utilization on the first connecting seat 110 and facilitating the installation of the first acceleration sensor 2311.

[0096] The second acceleration sensor 2312 can be arranged in the second weight reduction groove 123, and there is no need to design an installation space for the second acceleration sensor 2312 on the second connecting seat 120 separately, which is beneficial to improving the space utilization on the second connecting seat 120 and facilitating the installation of the second acceleration sensor 2312.

[0097] Among them, the wireless transmission device 233 and the force sensor 232 can be arranged in the first weight reduction groove 113 or the second weight reduction groove 123. The installation positions of the wireless transmission device 233 and the force sensor 232 are not specifically limited here, as long as the wireless transmission device 233 can be electrically connected to the force sensor 232 and the acceleration sensor 231 respectively.
