Description

Seismic isolation foundation for preventing uneven settlement of supporting power equipment Technical Field

[0001] The present invention relates to the field of power transmission, and in particular to a seismic isolation foundation for preventing uneven settlement of supporting power equipment. Background Art

[0002] The southwest region is an important energy base in my country, but the risk of earthquakes in the southwest region is relatively high, posing a huge threat to local power facilities. In addition, the environment in Tibet's high-altitude areas is harsh and permafrost is widespread. The seasonal freeze-thaw cycle of permafrost can cause uneven settlement of the foundation, causing relative deformation between equipment in the coupling circuit, resulting in excessive deformation of hardware, jamming, or even damage. Currently, the main method used for seismic isolation of supporting power equipment is swing-type bearings, which have seismic isolation functions but are difficult to deal with uneven settlement problems. In terms of settlement caused by the freeze-thaw cycle of permafrost, the main methods used are foundation treatment, preventing permafrost from freezing, and setting deep foundations, but these methods cannot achieve seismic isolation effects.

[0003] Summary of the Invention

[0004] Based on this, it is necessary to provide a seismic isolation foundation for preventing uneven settlement of pillar power equipment in order to solve the problem that the current seismic isolation foundation of pillar power equipment cannot simultaneously have the functions of seismic isolation and prevention of uneven settlement.

[0005] The technical solution is as follows:

[0006] On the one hand, a seismic isolation foundation for preventing uneven settlement of supporting power equipment is provided, comprising:

[0007] a base layer, the base layer being disposed on the fill layer, a mounting hole being provided on a top of the base layer, the mounting hole extending to the fill layer; and

[0008] The swing isolation assembly includes an energy-absorbing member and a swing member. The swing member is arranged in the mounting hole at intervals, and the energy-absorbing member is arranged between the swing member and the inner side wall of the mounting hole.

[0009] The isolation foundation for preventing uneven settlement of pillar power equipment in the above embodiment is used. When the pillar power equipment is installed on the fill layer through the equipment bracket isolation foundation, and two adjacent pillar power equipment can be electrically connected through hardware to achieve the installation of the pillar power equipment. When the fill layer undergoes local uneven settlement, since the foundation layer is a whole, the contact area between the foundation layer and the fill layer is large, and the rigidity of the foundation layer is also large, it is ensured that the foundation layer will not undergo obvious deformation, and the foundation layer and the swing isolation assembly can be separated, thereby ensuring the stability of the energy-absorbing parts and the shape of the swing parts installed in the installation hole, and achieving the effect of preventing uneven settlement. When an earthquake occurs in the fill layer, causing the swing part to swing, the swing part will squeeze the energy-absorbing part, and then the energy-absorbing part can undergo elastic deformation to consume the kinetic energy of the swing part, thereby reducing the swing amplitude of the swing part and achieving the isolation effect. Compared to existing isolation foundations for pillar power equipment, the isolation foundation in this application, designed to prevent uneven settlement of pillar power equipment, combines both uneven settlement prevention and seismic isolation through the coordination of the foundation layer and the rocking isolation assembly, ensuring stable and reliable operation of the pillar power equipment. Furthermore, the isolation foundation eliminates the need for additional isolation bearings, creating a clear interface between civil engineering and power construction, facilitating the construction of equipment supports, pillar power equipment, and hardware.

[0010] The technical solution is further described below:

[0011] In one embodiment, the rocking isolation assembly further includes a support member, which is disposed in the fill layer and extends to the bottom of the mounting hole. The support member is used to support the rocking member so that the top of the support member is the rotation center of the rocking member.

[0012] In one embodiment, a rocking end is provided at the bottom of the rocking member, and the rocking end is movably disposed on the top of the support member.

[0013] In one embodiment, the rocking end is a conical surface or an arc surface.

[0014] In one embodiment, the inner side wall of the mounting hole, the energy absorbing member, the swing end and the fill layer form a filling space, and the swing isolation assembly further includes a fluid member, which fills the filling space.

[0015] In one embodiment, the rocking member is provided with a cavity.

[0016] In one embodiment, the outer contour of the outer side wall of the energy dissipation component matches the inner contour of the inner side wall of the mounting hole, and the outer side wall of the energy dissipation component is in contact with and connected to the inner side wall of the mounting hole.

[0017] In one embodiment, the rocking isolation assembly further includes a shielding member, which is located above the energy dissipation member and covers a gap between the rocking member and an inner side wall of the mounting hole.

[0018] In one embodiment, there are at least two mounting holes, and two adjacent mounting holes are spaced apart from each other. There are at least two rocking isolation assemblies, and each rocking isolation assembly is corresponding to each mounting hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0026] The inventors conducted further research and analysis on the seismic isolation foundations of current pillar power equipment and found that the seismic isolation foundations of current pillar power equipment still have the following problems: (1) Seismic isolation supports need to be additionally provided, and these supports are unstable under the influence of wind, earthquakes, etc., that is, under large deformation, the entire structure may overturn. (2) Existing anti-settlement technology is mainly aimed at single equipment, while there are many devices in the coupling circuit, and their uneven settlement has a greater impact on the hardware, so the foundation setting of the entire circuit also needs to be considered.

[0027] Based on this, the following embodiments of the present application are designed to provide an isolation foundation 400 and a power transmission system 10 for preventing uneven settlement of supporting power equipment 200 to solve the above technical problems.

[0028] As shown in Figures 1 and 2, in one embodiment, a seismic isolation foundation 400 for preventing uneven settlement of supporting power equipment 200 is provided, comprising a foundation layer 410 and a rocking isolation assembly 420. The foundation layer 410 is disposed on a fill layer 500, and a mounting hole 411 is defined at the top of the foundation layer 410, extending into the fill layer 500. The rocking isolation assembly 420 comprises an energy dissipation member 421 and a rocking member 422, wherein the rocking member 422 is spaced apart within the mounting hole 411, and the energy dissipation member 421 is disposed between the rocking member 422 and the inner wall of the mounting hole 411.

[0029] In the above-mentioned embodiment, the seismic isolation foundation 400 for preventing uneven settlement of the pillar power equipment 200 is used. When the pillar power equipment 200 is installed on the fill layer 500 via the equipment bracket 100 and the seismic isolation foundation 400, two adjacent pillar power equipment 200 can be electrically connected via the hardware 300 to achieve the installation of the pillar power equipment 400. When the fill layer 500 undergoes local uneven settlement, since the foundation layer 410 is a whole, the contact area between the foundation layer 410 and the fill layer 500 is large, and the rigidity of the foundation layer 410 is also large, ensuring that the foundation layer 410 will not undergo significant deformation, and the foundation layer 410 and the rocking isolation group 420 can be separated, thereby ensuring the shape stability of the energy dissipation component 421 and the rocking component 422 installed in the mounting hole 411, achieving the effect of preventing uneven settlement. When an earthquake occurs in the fill layer 500, causing the rocking member 422 to rock, the rocking member 422 will squeeze the energy-absorbing member 421, thereby causing the energy-absorbing member 421 to undergo elastic deformation to consume the kinetic energy of the rocking member 422, thereby reducing the swing amplitude of the rocking member 422 and achieving the effect of seismic isolation. Compared with the existing seismic isolation foundation 400 of the pillar power equipment 200, the seismic isolation foundation 400 in the present application for preventing uneven settlement of the pillar power equipment 200 cooperates with the base layer 410 and the rocking isolation assembly 420 to have both the functions of preventing uneven settlement and seismic isolation, thereby ensuring that the pillar power equipment 200 can operate stably and reliably. In addition, the seismic isolation foundation 400 does not require additional seismic isolation bearings, and the interface between civil engineering and power construction is clear, which facilitates the construction of equipment such as equipment brackets 100, pillar power equipment 200 and hardware 300.

[0030] The energy dissipation member 421 may be a spring, a damper or other energy dissipation structures, and the rocking member 422 may be a rocking hemisphere, a rocking cone or other rocking structures.

[0031] Specifically, in this embodiment, the fill layer 500 can be a ground layer. The foundation layer 410 can be a reinforced concrete foundation slab. The energy dissipation component 421 can be a damper. This provides high stability for the seismic isolation foundation 400. Specifically, during earthquakes or strong winds, the damper's stiffening effect allows for controllable deformation of the entire hardware 300.

[0032] The number of dampers can be flexibly adjusted based on actual usage needs. The dampers are annular, with at least two dampers provided, each positioned along the axis of the mounting hole. In other embodiments, the energy dissipation element 421 can be a wire rope isolator, which has three-dimensional deformation capability and high damping and energy dissipation capacity.

[0033] As shown in Figures 1 and 2, optionally, there are at least two mounting holes 411, and adjacent mounting holes 411 are spaced apart. There are at least two swing isolation assemblies 420, and each swing isolation assembly 420 is correspondingly provided to each mounting hole 411. In this way, each swing member 422 can be mounted with a corresponding device bracket 100 and a pillar power device 200, and multiple pillar power devices 200 are electrically connected via hardware 300 to form a coupling loop, ensuring that the relative positions of the devices within the coupling loop remain fixed, preventing the hardware 300 from becoming stuck or even damaged due to excessive deformation, and improving the reliability and safety of the pillar power devices 200.

[0034] The plurality of mounting holes 411 may be arranged along a straight line, along a curve, or along a broken line.

[0035] As shown in Figures 1 and 2, in one embodiment, the rocking isolation assembly 420 further includes a support member 423, which is disposed in the fill layer 500 and extends to the bottom of the mounting hole 411. The support member 423 is used to support the rocking member 422, such that the top of the support member 423 serves as the rotation center of the rocking member 422. In this way, the support member 423 can vertically support the rocking member 422. When the fill layer 500 at the mounting hole 411 undergoes uneven settlement, the support member 423 can support the rocking member 422, thereby reducing the settlement clearance of the rocking member 422 and, in turn, reducing the settlement distance of the supporting power equipment 200 on the rocking member 422. This prevents the hardware 300 from being stuck or even damaged due to excessive deformation, thereby improving the reliability and safety of the supporting power equipment 200.

[0036] The support member 423 may be a support column, a support block, a support pile or other support structure. Specifically in this embodiment, the support member 423 is configured as a friction pile, and the center axis of the friction pile is aligned with the center axis of the mounting hole 411 .

[0037] As shown in Figures 2 and 3 , the bottom of the rocking member 422 is further provided with a rocking end 4221, which is movably mounted on the top of the support member 423. Thus, when an earthquake strikes the fill layer 500, causing the rocking end 4221 to rock about the top of the support member 423, the rocking end 4221 drives the rocking member 422 to swing along a predetermined trajectory, thereby squeezing the energy dissipation member 421. This, in turn, causes the energy dissipation member 421 to elastically deform, dissipating the kinetic energy of the rocking member 422. This reduces the rocking amplitude of the rocking member 422 and improves the reliability of the seismic isolation of the seismic isolation foundation 400.

[0038] Specifically, in this embodiment, the swing end 4221 can be configured as a conical surface. Thus, when an earthquake strikes the fill layer 500, causing the conical surface to swing about the top of the support member 423, the conical surface drives the swing member 422 to swing along a predetermined trajectory, squeezing the energy dissipation member 421. This causes the energy dissipation member 421 to elastically deform, dissipating the kinetic energy of the swing member 422. This reduces the swing amplitude of the swing member 422 and improves the reliability of the seismic isolation of the seismic isolation foundation 400.

[0039] In other embodiments, the swing end 4221 may also be configured as an arcuate surface. Thus, when an earthquake strikes the fill layer 500, causing the arcuate surface to swing about the top of the support member 423, the arcuate surface drives the swing member 422 to swing along a predetermined trajectory, squeezing the energy dissipation member 421. This causes the energy dissipation member 421 to elastically deform, dissipating the kinetic energy of the swing member 422. This reduces the swing amplitude of the swing member 422 and improves the reliability of the seismic isolation of the seismic isolation foundation 400.

[0040] As shown in Figures 2 and 3 , optionally, the inner wall of the mounting hole 411, the energy dissipation component 421, the swing end 4221, and the fill layer 500 enclose a filling space. The swing isolation assembly 420 further includes a fluid component 424 that fills the filling space. In this manner, the fluid component 424 within the filling space forms a fluid cushion. This fluid cushion is relatively loose and has low rigidity, facilitating the swinging of the swing component 422 within the mounting hole 411 to compress the energy dissipation component 421, thereby improving the reliability and stability of the seismic isolation foundation 400.

[0041] The flowing member 424 may be fine sand, fine stone or other flowing structures.

[0042] As shown in Figures 2 and 3, in one embodiment, the rocking member 422 is provided with a cavity 4222. This cavity can reduce the mass of the rocking member 422 and improve the seismic isolation effect of the seismic isolation foundation 400. Specifically, in this embodiment, the cavity 4222 is located inside the rocking member 422.

[0043] Optionally, the rocking member 422 includes a rocking body and a cover plate. The rocking end 4221 is disposed at the bottom of the rocking body. The top of the rocking body is provided with a groove, and the cover plate is disposed in the groove. The rocking body and the cover plate enclose the cavity 4222, and the cover plate is made of steel. This further reduces the mass of the rocking member 422, thereby improving the seismic isolation effect of the seismic isolation foundation 400.

[0044] As shown in Figures 2 and 3 , the outer contour of the outer wall of the energy dissipation member 421 optionally matches the inner contour of the inner wall of the mounting hole 411, and the outer wall of the energy dissipation member 421 is in contact with the inner wall of the mounting hole 411. This allows the energy dissipation member 421 to separate from the foundation layer 410, reducing energy transfer between them and achieving base isolation. Furthermore, when the foundation layer 410 settles, the foundation layer 410 can sink relative to the energy dissipation member 421, reducing the impact of the foundation layer 410 on the settlement of the energy dissipation member 421 and the rocking member 422, thereby preventing uneven settlement.

[0045] As shown in Figures 2 and 3 , the rocking isolation assembly 420 optionally further includes a shielding member 425. The shielding member 425 is positioned above the energy dissipation member 421 and covers the gap between the rocking member 422 and the inner wall of the mounting hole 411. Thus, the shielding member 425 prevents rainwater from entering the gap between the rocking member 422 and the inner wall of the mounting hole 411, ensuring stable and reliable operation of the energy dissipation member 421 and improving the reliability and service life of the isolation foundation 400.

[0046] As shown in Figures 1 and 2, in one embodiment, a power transmission system 10 is provided, including an equipment bracket 100, a pillar power equipment 200, hardware 300 and a seismic isolation foundation 400. The equipment bracket 100 is installed on the top of the rocking member 422, the pillar power equipment 200 is installed on the equipment bracket 100, and the hardware 300 is used to electrically connect the pillar power equipment 200 with the adjacent pillar power equipment 200.

[0047] In the power transmission system 10 of the above embodiment, when in use, the support power equipment 200 is installed on the fill layer 500 via the equipment bracket 100 and the isolation foundation 400. Adjacent support power equipment 200 can be electrically connected via the hardware 300. This ensures that when the fill layer 500 experiences an earthquake or uneven settlement, the relative positions of the devices within the coupling circuit of the power transmission system 10 remain fixed, preventing the hardware 300 from becoming stuck or even damaged due to excessive deformation, thereby improving the reliability and safety of the power transmission system 10. When the fill layer 500 experiences local uneven settlement, the foundation layer 410, being a single unit, has a large contact area with the fill layer 500 and a high rigidity, ensuring that the foundation layer 410 does not significantly deform. Furthermore, the foundation layer 410 can be separated from the rocking isolation assembly 420, thereby maintaining the shape stability of the energy dissipation component 421 and the rocking component 422 installed in the mounting hole 411 and achieving the effect of preventing uneven settlement. When an earthquake occurs in the fill layer 500, causing the rocking member 422 to rock, the rocking member 422 will squeeze the energy-absorbing member 421, thereby causing the energy-absorbing member 421 to undergo elastic deformation to consume the kinetic energy of the rocking member 422, thereby reducing the swing amplitude of the rocking member 422 and achieving the effect of seismic isolation. Compared with the existing seismic isolation foundation 400 of the pillar power equipment 200, the seismic isolation foundation 400 in the present application for preventing uneven settlement of the pillar power equipment 200 has the functions of preventing uneven settlement and seismic isolation through the cooperation of the base layer 410 and the rocking isolation assembly 420, thereby ensuring that the pillar power equipment 200 can operate stably and reliably. In addition, the seismic isolation foundation 400 does not require additional seismic isolation bearings, and the interface between civil engineering and power construction is clear, which facilitates the construction of equipment such as the equipment bracket 100, the pillar power equipment 200 and the hardware 300, thereby improving the convenience and reliability of the power transmission system 10.

[0048] The power transmission system 10 may be configured as a transformer station or a converter station.
