Description

Technical Field

[0001] The present invention relates to the technical field of seismic isolation system design. Specifically, it is to design a seismic isolation system layout and a standardized design method. Background Art

[0002] Cabinet is an important device needed in daily production and life, including railway communication cabinets, aerospace signal processing cabinets, enterprise and institution electrical control cabinets, etc. During the operation of the cabinet, ensuring its installation and operation stability is an important way to maintain its normal operation. And China has multiple seismic belts, and the vibrations brought by earthquakes or other vibrations pose a huge threat to the operation of the cabinet. In order to ensure the stable operation of the cabinet, a seismic isolation device is a common cabinet installation protection system.

[0003] Existing cabinet seismic isolation devices mostly include motion buffer structures in two mutually perpendicular directions. The cabinet can be placed on the seismic isolation device to achieve the seismic isolation function. However, existing seismic isolation devices mostly support and isolate a single cabinet. There are also some foreign seismic isolation devices (such as THK in Japan and ISO-BASE in the United States) that can achieve seismic isolation design for multiple cabinets. However, the design idea of such seismic isolation is that two adjacent seismic isolation devices simultaneously isolate a single cabinet, and the distance between the seismic isolation devices is equal to the width of the cabinet. This results in a large density of seismic isolation devices and a large design investment when arranging the seismic isolation devices.

[0004] In addition, the anti-static floor is an important part of the data center infrastructure. It can prevent static electricity from harming the normal operation of equipment and can optimize wiring, heat dissipation, and operation and maintenance efficiency through structured design. When no seismic isolation device is used, the data cabinet is directly fixed or placed on the anti-static floor; when a seismic isolation device is used, there is a spatial displacement contradiction between the seismic isolation device and the anti-static floor, resulting in the need to place the seismic isolation device on the anti-static floor, or when installed at the opening of the anti-static floor, the upper side of the seismic isolation device needs to be exposed on the surface of the anti-static floor, which will affect the aesthetics of the entire anti-static floor and also cause a problem of large space occupation.

[0005] Therefore, there is a need for a seismic isolation system that can be designed for different electromechanical systems and a standardized design for the seismic isolation system. Summary of the Invention

[0006] In order to overcome the deficiencies of the existing technology, the present invention provides a seismic isolation system layout and a standardized design method.

[0007] The technical solution of the present invention is as follows:

[0008] On the one hand, a seismic isolation system arrangement is installed at the installation opening of the floor, and is characterized in that it includes one or more rows of seismic isolation modules. Each row of the seismic isolation modules includes more than one seismic isolation unit, and each seismic isolation unit includes:

[0009] Two seismic isolation devices, the two seismic isolation devices are arranged side by side and spaced from each other in the first direction, and each seismic isolation device is located under the adjacent two cabinets;

[0010] A cross beam, the cross beam is located above the two seismic isolation devices, so that the adjacent two seismic isolation devices form an integral body, and the upper surface of the cross beam is higher than the upper surface of the floor, and the lower surface of the cross beam is lower than the lower surface of the floor.

[0011] According to the present invention of the above solution, it is characterized in that each seismic isolation unit further includes a middle connecting member arranged in the first direction, and the sides of the adjacent two seismic isolation devices are connected by the middle connecting member, so that the adjacent two seismic isolation units move synchronously.

[0012] According to the present invention of the above solution, it is characterized in that the cross beam is installed on the corresponding seismic isolation device through a cross beam fixing member.

[0013] According to the present invention of the above solution, it is characterized in that in each seismic isolation unit, an end connecting member is provided at the end of the cross beam, and the cabinet is installed on the cross beam and supported above the end connecting member.

[0014] According to the present invention of the above solution, it is characterized in that a unit connecting member is further provided between two adjacent seismic isolation units in the same row, and the unit connecting member is used to connect the adjacent two seismic isolation units, so that the two seismic isolation units move synchronously.

[0015] According to the present invention of the above solution, it is characterized in that an inter-row connecting member is further provided between two adjacent rows of seismic isolation modules, and the inter-row connecting member is used to connect the adjacent two seismic isolation modules, so that the two seismic isolation modules move synchronously.

[0016] On the other hand, a seismic isolation system standardization design method is characterized in that, based on the above seismic isolation system arrangement, it includes the following steps:

[0017] S1. Select seismic waves to conduct ground motion simulation on the seismic isolation device, and obtain the maximum displacement of the seismic isolation device under the set conditions as the minimum installation threshold;

[0018] S2. Select a cross beam model, the height of the cross beam is greater than the thickness of the floor, and the distance between the edge of the seismic isolation device in the natural state and the surrounding floor, and the distance between the end of the cross beam and the surrounding floor are not less than the minimum installation threshold;

[0019] S3. Standardize the layout of the seismic isolation units so that the two seismic isolation devices are respectively located directly below the connection positions of the two cabinets at both ends in the first direction;

[0020] S4. Standardize the length of the cross beam. Perform finite element analysis based on the bearing capacity and structural performance of the seismic isolation device, and the weights of the cabinet and internal equipment to determine the length of the cross beam;

[0021] S5. Determine the layout and connection relationship of each seismic isolation unit in the seismic isolation system according to the layout requirements;

[0022] S6. Construct a force-dispersing frame so that after the seismic isolation unit is installed on the force-dispersing frame, the upper surface of the cross beam is higher than the upper surface of the floor, and the lower surface of the cross beam is lower than the lower surface of the floor.

[0023] The present invention according to the above solution is characterized in that in step S1, 7 seismic waves are selected and ground motion simulation is carried out according to the rare earthquake of intensity 9.

[0024] The present invention according to the above solution is characterized in that in step S4, the length of the cross beam is standardized, that is, it satisfies: L≤nD - 2W - 2T,

[0025] where L is the length of the cross beam, n is a positive integer, D is the width of each cabinet, W is the minimum installation threshold, and T is the thickness of the end connector.

[0026] The present invention according to the above solution is characterized in that after the design of the seismic isolation unit or the design of the seismic isolation system is completed, layout debugging and optimization are carried out: perform finite element analysis and verification on the seismic isolation unit or the seismic isolation system. For the design model that does not meet the seismic isolation requirements, shorten the cross beam model by the width dimension of one cabinet and then perform finite element analysis again until the system requirements are met.

[0027] The beneficial effect of the present invention according to the above solution is that the present invention uses a cross beam to connect two seismic isolation devices, combines the two seismic isolation devices to form a seismic isolation unit, and then designs a large number of seismic isolation systems based on the seismic isolation unit, so that it can be applied to the electromechanical system with multiple cabinet installations, enabling multiple seismic isolation units to be assembled into a complete whole without mutual influence. At the same time, the application quantity of the seismic isolation units can be reduced, and the load-bearing performance of the seismic isolation units can be guaranteed, which is beneficial to the seismic isolation of large data cabinet systems such as cabinet micro-modules.

[0028] Through the mutual cooperation of structures such as the seismic isolation device and the cross beam, the present invention can make the seismic isolation device hidden at the installation opening of the floor, with better aesthetics of the whole system, and can realize the full and reasonable utilization of the floor space.

[0029] Through the standardized design of the crossbeam and the standardized design of the seismic isolation unit, the present invention can reasonably design the cooperation relationship between the seismic isolation system and the cabinet while solving the contradiction between the displacement of the floor and the seismic isolation system and achieving an aesthetic design. The design of the seismic isolation system is simpler and faster, and the application of the seismic isolation system is safer.

[0030] In the present invention, the seismic isolation units are distributed at the middle positions between two adjacent cabinets, so that the force on the seismic isolation units is more uniform, the line layout below the cabinets is not affected, and the standardized design of each connecting piece can also be achieved.

[0031] The seismic isolation units in the present invention are connected by middle connecting pieces, which can not only ensure the synchronous movement of the seismic isolation units in the transverse direction, but also increase the integrity of the seismic isolation system and further improve the load-bearing capacity of the seismic isolation system.

[0032] Through the mutual cooperation of the seismic isolation unit, the crossbeam and the middle connecting piece, the present invention can achieve the standardized design of the seismic isolation system, so that the seismic isolation system can be applied to different installation occasions, which is beneficial to designing different installation methods according to different requirements. The design of the seismic isolation system is simpler and faster, and the application of the seismic isolation system is safer. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0050] The present invention will be further described below in conjunction with the accompanying drawings and the implementation manner:

[0051] As Figures 1 to 15 shown, in order to achieve seismic isolation support for grouped electromechanical equipment and adapt to the standardized design process, the present invention provides a seismic isolation system layout and a standardized design method, which can assemble multiple seismic isolation units into one body, ensuring both the integrity of the system and improving the load-bearing capacity of the seismic isolation system, and can also achieve standardized design.

[0052] As Figures 1 to 15 shown, the present invention provides a seismic isolation system layout, which is installed at the installation opening 610 of the floor 600, used to support the cabinet 500 above the floor and hide components such as the seismic isolation system. The floor 600 in the present invention is preferably an anti-static floor, which is supported by brackets in places such as computer rooms.

[0053] The seismic isolation system layout includes one or more rows of seismic isolation modules. Each row of seismic isolation modules can support and isolate multiple cabinets 500 in the same row. The system formed by connecting multiple rows of seismic isolation modules to each other can also isolate the cabinet micro-module. In the present invention, one row of seismic isolation modules is mostly applied to the case where multiple cabinets 500 are arranged side by side, and more than two rows of seismic isolation modules are mostly used in the application scenario of the cabinet micro-module. The cabinet micro-module is a software and hardware integration solution that integrates computing, storage, and network resources in a standardized module. The seismic isolation design must ensure the consistency of the overall movement of the cabinet micro-module during an earthquake. Otherwise, problems such as damage to connecting parts and cracking of skylight glass will occur. Therefore, the seismic isolation system layout of the present invention can ensure the consistency of the movement of the cabinets during an earthquake while achieving an aesthetic structural design and a stable system structure.

[0054] Each row of seismic isolation modules includes more than one seismic isolation unit. Each seismic isolation unit includes two seismic isolation devices 100 and a crossbeam 200 connecting the two seismic isolation devices. The two seismic isolation devices 100 are arranged side by side and spaced apart in the first direction. Each seismic isolation device 100 is located under the adjacent two cabinets 500 to support and isolate the two cabinets 500 respectively; the crossbeam 200 is arranged along the first direction, and the crossbeam 200 is located above the two seismic isolation devices 100, so that the adjacent two seismic isolation devices 100 form an integral body, and the upper surface of the crossbeam 200 is higher than the upper surface of the floor 600, and the lower surface of the crossbeam 200 is lower than the lower surface of the floor 600. Through the mutual cooperation of the two seismic isolation devices 100 and the crossbeam 200, they form an integral body to ensure the consistency of the movement of all cabinets during an earthquake and avoid problems such as damage to connecting parts and cracking of skylight glass.

[0055] Each seismic isolation device 100 is located under the adjacent two cabinets 500, which can not only enable the seismic isolation device 100 to support a row of cabinets at the same time, effectively exert its supporting ability, reduce the application of the seismic isolation device 100, but also ensure the stability of the cabinet 500, and facilitate the routing and layout of pipelines under the cabinet. In a specific embodiment, each seismic isolation device includes a base assembly, a sliding assembly, and a top plate assembly arranged in sequence from bottom to top. The crossbeam is installed on the corresponding top plate assembly through a crossbeam fixing member, so that the crossbeam and the cabinet above it reciprocate in the second direction relative to the floor and reciprocate in the first direction relative to the sliding assembly. Since the structure of the seismic isolation device is not an improvement of the present invention, the functions described in the present invention can be realized by using various existing seismic isolation devices. Therefore, the present invention does not limit the specific structure of the seismic isolation device. The first direction and the second direction in the present invention are perpendicular to each other.

[0056] The crossbeam 200 is installed on the corresponding seismic isolation device through the crossbeam fixing member 210 and self-tapping screws. Specifically, the crossbeam fixing member 200 is an angle steel, one side wall of which is installed on the seismic isolation device 100 through self-tapping screws, and the other side wall is installed on the side wall of the crossbeam 200 through self-tapping screws. Through this structure, the rapid assembly of the crossbeam 200 and the seismic isolation device 100 can be realized. After the seismic isolation system design is completed, the system assembly and the fixing of the cabinet 500 can be quickly realized according to the design model. Preferably, the crossbeam 200 spans all the seismic isolation devices 100 in the same row, and the end of the crossbeam 200 protrudes outside the seismic isolation device 100 at the end. On the one hand, all the seismic isolation devices 100 in the same group can be connected through the crossbeam 200, and the design that one seismic isolation device 100 is located in the middle of two cabinets 500 can be satisfied. In addition, the seismic isolation device 100 can be hidden under the cabinet 500, making the seismic isolation structure more beautiful.

[0057] The crossbeam 200 in the present invention is a hollow square tube. Through the square tube, its rapid fixation with the seismic isolation device 100 can be realized. At the same time, the cabinet 500 can be more conveniently installed on the square tube, and the weight of the structural components above the seismic isolation device 100 can be minimized. For example, a square tube with dimensions of 100mm×50mm×5mm and a load-bearing specification of 10.4kg / m can be selected for support, or a square tube with dimensions of 100mm×50mm×4mm and a load-bearing specification of 8.5kg / m can be used for support.

[0058] In each seismic isolation device 100, an end connector 400 is provided at the end of the crossbeam 200. The cabinet 500 is installed on the crossbeam 200 and supported on the upper side of the end connector 400. Specifically, the cross-section of the end connector 400 is L-shaped, one side wall of which is fixedly connected to the crossbeam 200, and the other side wall is used to support the cabinet 500; and the upper surface of the end connector 400 is flush with the upper surface of the crossbeam 200, so that the two can support the cabinet 500 synchronously to ensure the stability of the cabinet 500. In this installation method, the end connector 400 is installed at the end of the crossbeam 200 through self-tapping screws and can be fixed to the cabinet 500 through self-tapping screws. This installation method is more convenient and fast.

[0059] Preferably, the lower wall of the end connector 400 is higher than the surface of the floor 600 ( Figure 3 H1 in the figure), but since the edge cabinet 500 extends beyond the end connector 400, and at the same time, since the upper wall of the end connector 400 is higher than the floor 600, during the seismic isolation movement of the seismic isolation system, the collision between the end connector 400 and the floor 600 will not be caused, and at the same time, the support length of the crossbeam 200 can be extended to ensure the installation stability of the cabinet 500.

[0060] In the present invention, in the natural state, the distance between the edge of the seismic isolation device 100 and the edge of the installation opening 610, and the distance between the end of the cross beam 200 and the edge of the installation opening 610 are both not less than the minimum installation threshold. As Figure 4 shown, the dashed box represents the maximum displacement of the seismic isolation system during the seismic influence movement process (obtained by simulating ground motion according to the rare earthquake of intensity 9 through 7 seismic waves (5 actual strong earthquake seismic waves and 2 synthetic seismic waves)). In order to avoid mutual interference between the seismic isolation system and the floor 600, in the present invention: (1) the distance between the end of the cross beam 200 and the edge of the installation opening 610 is not less than the minimum installation threshold W; (2) the upper surface of the cross beam 200 is higher than the upper surface of the floor 600, and the lower surface of the cross beam 200 is lower than the lower surface of the floor 600. This enables the cabinet 600 to Figure 4 move within the range shown by the dashed box without causing mutual interference between the seismic isolation system and the floor.

[0061] In Figure 3 , the dimension by which the upper surface of the cross beam 200 (actually the lower surface of the end connector 400) is higher than the upper surface of the floor 600 is H1; the dimension by which the lower surface of the cross beam 200 is lower than the lower surface of the floor 600 is H2. Preferably, the height of the cross beam 200 is greater than the thickness of the floor 600 by not less than 10 mm. Without considering the end connector 400, the upper surface of the cross beam 200 is 5 mm higher than the upper surface of the floor 600 (i.e., H1 = 5 mm), and the lower surface of the cross beam 200 is 5 mm lower than the lower surface of the floor 600 (i.e., H2 = 5 mm).

[0062] Each seismic isolation unit further includes a middle connector 300 arranged along the first direction. The sides of adjacent two seismic isolation devices 100 are connected by the middle connector 300, so that the adjacent two seismic isolation devices 100 move synchronously. The middle connector 300 of the present invention connects the front end parts and the rear end parts of adjacent two seismic isolation devices 100, which neither affects the installation of the cabinet 500, and at the same time can ensure the synchronous movement of multiple seismic isolation devices 100 in the left - right direction and the front - rear direction. Preferably, in the Figures 6 to 10 shown embodiment, the middle connector 300 is connected to the end parts of the sliding components of two seismic isolation devices 100, so that the two seismic isolation devices 100 can move synchronously in both the first direction and the second direction.

[0063] When the seismic isolation system of the present invention is applied to a single - row seismic isolation module, a unit connector 800 arranged along the first direction is provided between adjacent two seismic isolation units in the same row. The unit connector 800 is used to connect adjacent two seismic isolation units, so that the two seismic isolation units move synchronously. Preferably, in the same - row seismic isolation module, the layout of multiple seismic isolation units is symmetrically designed to ensure more balanced stress of the entire cabinet system.

[0064] Preferably, the unit connecting member 800 is connected to the adjacent seismic isolation devices 100 between two seismic isolation units. Specifically, the left side of the unit connecting member 800 is connected to the top plate assembly or the sliding assembly of the right seismic isolation device in the left seismic isolation unit, and the right side of the unit connecting member 800 is connected to the base assembly or the sliding assembly of the left seismic isolation device in the right seismic isolation unit to ensure that the two seismic isolation units can move synchronously in both the first direction and the second direction.

[0065] When the seismic isolation system of the present invention is applied to multiple rows of seismic isolation modules, based on the aforementioned single-row seismic isolation module, an inter-row connecting member 900 arranged in the second direction is provided between two adjacent rows of seismic isolation modules. The inter-row connecting member 900 is used to connect two adjacent seismic isolation modules to make the two seismic isolation modules move synchronously. In this case, the structural design of each row of seismic isolation modules is the same so that the inter-row connecting member can be installed on the corresponding seismic isolation units / seismic isolation devices between the two seismic isolation modules to ensure a more uniform layout of the entire system.

[0066] Preferably, the inter-row connecting member 900 is connected to the corresponding seismic isolation device 100 between two seismic isolation modules. Specifically, one end of the inter-row connecting member is connected to the top plate assembly of the seismic isolation device in a seismic isolation unit in the first row of seismic isolation modules, and the other end of the inter-row connecting member is connected to the top plate assembly of the seismic isolation device in the seismic isolation unit at the corresponding position in the second row of seismic isolation modules to ensure that the two seismic isolation modules can move synchronously in both the first direction and the second direction.

[0067] In the present invention, the seismic isolation system is installed on the force-dispersing frame 700. The support of the seismic isolation system is realized through the force-dispersing frame 700, and at the same time, it can cooperate with the design of the installation opening 610 of the floor 600 to meet the installation requirements.

[0068] A method for the standardized design of a seismic isolation system, based on the above arrangement of the seismic isolation system, can realize the rapid standardized design of the cabinet seismic isolation system, making the design of the cabinet seismic isolation system more convenient and ensuring the safety of the seismic isolation system. The seismic isolation standardized design method includes the following steps:

[0069] 1. Determine the minimum installation threshold for the installation of the seismic isolation device.

[0070] Select seismic waves for the seismic isolation device and conduct ground motion simulation according to its seismic isolation performance, and obtain the maximum displacement of the seismic isolation device under the set conditions as the minimum installation threshold.

[0071] Specifically, 7 seismic waves are selected for ground motion simulation according to the rare earthquake of intensity 9. Preferably, among the 7 seismic waves, 5 are actual strong seismic waves and 2 are artificial synthetic seismic waves, so as to obtain a more comprehensive seismic isolation effect.

[0072] 2. Select the beam model.

[0073] The height of the selected cross beam is greater than the thickness of the floor, and the distances between the edges of the seismic isolation device in the natural state and the surrounding floor and between the ends of the cross beam and the surrounding floor are not less than the minimum installation threshold.

[0074] As Figure 3 shown, the height of the cross beam is greater than the thickness of the floor by not less than 10 mm, its upper surface is higher than the upper surface of the floor by H1 = 5 mm, and its lower surface is lower than the lower surface of the floor by H2 = 5 mm. This can not only make the gap of the installation opening smaller and ensure the aesthetics, but also prevent the floor from interfering with the movement of the cross beam.

[0075] 3. Standardized design of the layout of the seismic isolation units

[0076] Standardize the installation positions of the seismic isolation units so that the two seismic isolation devices are respectively located directly below the connection positions of the two cabinets at the two ends in the first direction, and the remaining cabinets are evenly arranged above the cross beam.

[0077] Preferably, considering that in the actual structure, the weights of the cabinets are not the same, when isolating vibration, install the cabinets with larger weights above the seismic isolation devices, and install the cabinets with smaller weights above the cross beam between the two seismic isolation devices.

[0078] 4. Standardized design of the length of the cross beam.

[0079] Standardize the length of the cross beam according to the number of cabinets. Based on the bearing capacity and structural performance of the seismic isolation device, and the weights of the cabinets and the internal equipment, perform finite element analysis to determine the length of the cross beam.

[0080] Specifically, the length of the cross beam adopts a standardized design, that is, it satisfies: L ≤ nD - 2W - 2T, where L is the length of the cross beam, n is a positive integer, D is the width of each cabinet, W is the minimum installation threshold, and T is the thickness of the end connector. In the present invention, n is an integer not less than 3, that is, the two seismic isolation devices can support and isolate at least three cabinets.

[0081] In the present invention, construct a mechanical analysis model of the seismic isolation device, the cross beam and the cabinet in a simulation software. Through finite element analysis, obtain the force model of the cross beam or the cross beam and the seismic isolation device, and determine whether the deformation amounts of the components after being stressed are within the threshold range. If the deformation amounts of all components after being stressed are within the allowed threshold range, it is determined that the model design is feasible. If the deformation amount of a component after being stressed exceeds the allowed threshold, reconstruct the model of the cross beam and perform mechanical analysis again until a suitable cross beam is selected. During the process of reconstructing the model of the cross beam, it is possible to choose to increase the wall thickness of the cross beam or reduce the size of the cross beam to reduce the number of cabinets supported by the seismic isolation unit composed of the two seismic isolation devices.

[0082] 5. Determine the layout and connection relationships of each isolation unit in the isolation system according to the layout requirements.

[0083] Specifically, according to the structure and spatial layout requirements of the electromechanical system, determine whether to construct a single-row isolation system or a multi-row isolation system, and determine the quantity and layout mode of the isolation units in each row of the isolation system.

[0084] A. When determining to select a single-row isolation system to construct a single-row isolation system: First, determine the quantity of the isolation units. When selecting more than 2 isolation units, multiple isolation units are arranged in series in the first direction, and unit connectors are provided between adjacent two isolation units so that all the isolation units are connected in series in the first direction.

[0085] B. When determining to select a multi-row parallel isolation system to construct a multi-row isolation system:

[0086] (1) Determine the quantity of the isolation modules and the quantity of the isolation units in each row of the isolation modules;

[0087] (2) Arrange each row of the isolation modules respectively: First, determine the quantity of the isolation units in the isolation module. When selecting more than 2 isolation units, multiple isolation units are arranged in series in the first direction, and unit connectors are provided between adjacent two isolation units so that all the isolation units are connected in series in the first direction;

[0088] (3) After arranging multiple rows of the isolation modules, arrange inter-row connectors between adjacent two rows of the isolation modules so that all the isolation modules are connected in series in the second direction.

[0089] It should be noted that when constructing a multi-row isolation system, the layout modes of the isolation modules in each row are the same so that the inter-row connectors between adjacent isolation modules can connect different isolation units in adjacent two rows of the isolation modules along the second direction.

[0090] 6. Construct a force-dispersing frame.

[0091] Construct a force-dispersing frame so that after the isolation units are installed on the force-dispersing frame, the upper surface of the cross beam is higher than the upper surface of the floor, and the lower surface of the cross beam is lower than the lower surface of the floor.

[0092] After completing the design of the isolation units or the design of the isolation system, conduct layout debugging and optimization: Conduct finite element analysis and verification on the isolation units or the isolation system. For the design models that do not meet the isolation requirements, shorten the cross beam model by the width dimension of one cabinet and then conduct finite element analysis again until the system requirements are met.

[0093] After the design of the single-row seismic isolation system is completed, during actual installation: First, install the seismic isolation device on the dispersion rack, and form a complete seismic isolation system through the middle connecting piece and the unit connecting piece; then place the cabinet flat on the crossbeam according to the design, and connect the bottom of the cabinet to the crossbeam with screws; finally, adjust the support position of the floor so that the installation opening avoids the maximum displacement space of the seismic isolation device.

[0094] As Figures 1 to 10 shown, in this embodiment, 6 cabinets form a single-row distribution form: 2 seismic isolation units cooperate with each other, and in each seismic isolation unit, two seismic isolation devices support 3 cabinets at the same time. Therefore, 3 seismic isolation units form an arrangement of 3 + 3. As Figure 11 shown, in this embodiment, 14 cabinets form a single-row distribution method: 3 seismic isolation units cooperate with each other, and in each seismic isolation unit, two seismic isolation devices support 4, 5, and 5 cabinets respectively at the same time. Therefore, 3 seismic isolation units form an arrangement of 4 + 5 + 5.

[0095] After the design of the multi-row seismic isolation system is completed, during actual installation: First, install the seismic isolation device on the dispersion rack according to the design, and form a complete seismic isolation system through the middle connecting piece, the unit connecting piece, and the inter-row connecting piece; then place the cabinet flat on the crossbeam according to the design, and connect the bottom of the cabinet to the crossbeam with screws; finally, adjust the support position of the floor so that the installation opening avoids the maximum displacement space of the seismic isolation device.

[0096] As Figures 12 to 14 shown, in this embodiment, 32 cabinets form a distribution form of two rows with 16 cabinets in each row. A two-row seismic isolation system is adopted, and each row of the seismic isolation system has 4 seismic isolation units; two seismic isolation devices in the 4 seismic isolation units support 3, 5, 5, and 3 cabinets respectively at the same time. Therefore, the 4 seismic isolation units in each row of the seismic isolation module form an arrangement of 3 + 5 + 5 + 3.
