Description

Technical Field

[0001] The present invention relates to the field of seismic isolation and vibration reduction of building structures, and more particularly, to a seismic isolation and vibration reduction floor system for electrical equipment. Background Art

[0002] As a facility in the power system that transforms, receives, and distributes electrical energy in terms of voltage and current, a substation is an important node to ensure the stable and safe transmission of electrical energy. However, the experience of multiple major earthquakes in recent years has shown that the electrical equipment in substations has poor seismic resistance due to the relatively weak strength and ductility of some components. It is extremely vulnerable to damage in strong earthquakes, and it is difficult to quickly restore power supply after the earthquake, which will seriously affect the earthquake relief work in the affected areas and even the social operation and economic development for a long period.

[0003] Currently, indoor substations usually arrange a large number of electrical equipment on the second floor or even higher floors. Under the action of an earthquake, as the floor height increases, the building structure will significantly amplify the ground acceleration, and the seismic action suffered by the electrical equipment on the high floors will increase exponentially. For high-intensity areas, it is more difficult for the existing seismic design of indoor substation building structures to meet the normal use limits of electrical equipment in terms of floor acceleration and other indicators.

[0004] Therefore, in order to avoid the damage of power equipment in indoor substations in high-intensity areas under the action of an earthquake and ensure normal power supply during the earthquake or rapid power restoration after the earthquake, the seismic isolation and vibration reduction measures for the electrical equipment floor are urgent problems to be solved.

[0005] To date, no effective solutions have been proposed for the above problems. Summary of the Invention

[0025] According to an embodiment of the present invention, there is provided an embodiment of a seismic isolation and vibration reduction floor system for electrical equipment. The seismic isolation and vibration reduction floor system includes: seismic isolation bearings and frame beams; a seismic isolation and vibration reduction floor, which is connected to the frame beams through the seismic isolation bearings, and various electrical equipment are arranged on the seismic isolation and vibration reduction floor; oil dampers, which are fixedly connected to the lower part of the seismic isolation and vibration reduction floor and are used to move together with the seismic isolation and vibration reduction floor in the event of an earthquake; viscous dampers, which are horizontally arranged between the oil dampers and the frame beams, and the viscous dampers are used to weaken the seismic action transmitted to the seismic isolation and vibration reduction floor.

[0026] Figure 1 is a schematic diagram of a cross-section of a seismic isolation and vibration reduction floor structure for electrical equipment according to an embodiment of the present invention, as Figure 1As shown in the figure, it includes: the seismic isolation and vibration reduction floor 1, the isolation bearing 2, the viscous damper 3, the oil damper 4, the oil damper medium 5, the frame beam 6, and the electrical equipment 7.

[0027] In this embodiment, the seismic isolation and vibration reduction floor 1 is connected to the frame beam 6 through the isolation bearing 2. A variety of electrical equipment 7 is arranged on the seismic isolation and vibration reduction floor 1, which can ensure the transfer of the load of the floor electrical equipment to the main frame, effectively weaken the seismic amplification effect of the main frame, and protect the safety of the electrical equipment.

[0028] Optionally, the seismic isolation and vibration reduction floor adopts a precast concrete floor slab.

[0029] In this embodiment, the seismic isolation and vibration reduction floor 1 can be cast-in-place with reinforced concrete or prefabricated in the factory, which can enhance the practicability.

[0030] Another option is that the types of isolation bearings include at least one of the following: rubber type, sliding type, and composite type.

[0031] In this embodiment, the isolation bearing 2 can adopt one or more of the rubber type, sliding type, and composite type, and its model and layout spacing can be set through special calculations, which are not limited here.

[0032] In this embodiment, the oil damper 4 is fixedly connected to the lower part of the seismic isolation and vibration reduction floor 1 and moves together with the seismic isolation and vibration reduction floor 1 during an earthquake, which can weaken the vibration of the seismic isolation and vibration reduction floor, improve the anti-overturning ability of the seismic isolation and vibration reduction floor, and protect the safety of the electrical equipment.

[0033] Optionally, an oil drain port is provided at the bottom of the oil damper, and a maintenance port is provided at the top of the oil damper.

[0034] Another option is that an oil damper medium is arranged inside the oil damper, and the types of the oil damper medium include: oil liquid, or a combination of oil liquid and pebbles.

[0035] In this embodiment, the oil damper 4 can also be cast-in-place with reinforced concrete or prefabricated in the factory to form an integral body with the seismic isolation and vibration reduction floor 1. During construction, anti-seepage measures can be taken inside the oil damper 4, an oil drain port is provided at the bottom, and a maintenance port is provided at the top for the daily maintenance of the internal medium. The internal medium of the oil damper 4 (i.e., the oil damper medium 5) can adopt oil liquid or a combination of oil liquid and pebbles, and the quantity of the oil liquid and pebbles arranged is set through special calculations. During an earthquake, the horizontal vibration of the seismic isolation and vibration reduction floor 1 can be reduced through the sloshing of the internal medium of the oil damper 4, and at the same time, the anti-overturning ability of the seismic isolation and vibration reduction floor is improved.

[0036] In this embodiment, a viscous damper 3 is horizontally arranged between the oil damper 4 and the frame beam 6.

[0037] Optionally, the viscous dampers are respectively fixedly connected to the side surface of the frame beam and the side of the oil damper.

[0038] In this embodiment, viscous dampers 3 can be horizontally arranged between the four sides of the oil damper 4 and the corresponding frame beams 6. Parameters such as the viscous coefficient of the viscous damper 3 and the number arranged on each side can be specifically calculated. The viscous dampers 3 are fixedly connected to the side of the frame beam 6 and the side of the oil damper 4 respectively. During an earthquake, the viscous dampers 3 can weaken the earthquake action transmitted to the seismic isolation and isolation floor 1 by consuming energy, and can also limit the maximum relative displacement between the seismic isolation and isolation floor 1 and the main frame, preventing damage to relevant electrical equipment due to excessive relative displacement of the isolation floor during an earthquake.

[0039] Figure 2 is a schematic three-dimensional diagram (upper part) of a seismic isolation and isolation floor for electrical equipment according to an embodiment of the present invention. As Figure 2 shown, it includes: a seismic isolation and isolation floor 1, a seismic isolation bearing 2, a viscous damper 3, an oil damper 4, a frame beam 6, electrical equipment 7, and a frame column 8.

[0040] Figure 3 is a schematic three-dimensional diagram (lower part) of a seismic isolation and isolation floor for electrical equipment according to an embodiment of the present invention. As Figure 3 shown, it includes: a seismic isolation and isolation floor 1, a seismic isolation bearing 2, a viscous damper 3, an oil damper 4, a frame beam 6, electrical equipment 7, and a frame column 8.

[0041] In this embodiment, as Figure 2 and Figure 3 shown, the seismic isolation and isolation floor 1 is arranged on the frame beam through the seismic isolation bearing 2. The lower part of the seismic isolation bearing 2 is fixedly connected to the connector embedded in the frame beam 6 through rigid materials such as bolts. The upper part of the seismic isolation bearing 2 can be fixedly connected to the seismic isolation and isolation floor 1 through anchor nails, bolts, cover plates, etc. The anchoring strength of the rigid material can be specifically checked. The seismic isolation and isolation floor 1 and its upper load are transmitted to the frame beam 6 through the seismic isolation bearing 2 and then transmitted to the frame column 8 through the frame beam 6. During an earthquake, the seismic isolation bearing 2 can effectively weaken the earthquake action transmitted from the main frame beam 6 to the seismic isolation and isolation floor 1, thereby reducing the floor acceleration and weakening the impact of the earthquake on the electrical equipment 7.

[0042] Alternatively, the frame beam 6 is connected to the base floor or other floors through the frame column 8, and a seismic isolation zone is provided between the frame column 8 and the seismic isolation and isolation floor 1. Among them, the seismic isolation zone is filled with a material with a hollow or preset flexibility.

[0043] In this embodiment, a seismic isolation zone is arranged around the frame column 8 of the seismic isolation and isolation floor 1. The width of the seismic isolation zone can be specifically checked to ensure that the floor 1 and the frame column 8 do not collide under earthquake action. According to the requirements of the use function, the seismic isolation zone can be hollow or filled with a material with a preset flexibility (the flexibility value can be set according to the specific situation).

[0044] Figure 4 is an optional bottom plane schematic diagram of a seismic isolation and vibration reduction floor for electrical equipment according to an embodiment of the present invention, as Figure 4 shown, including: viscous damper 3, oil damper 4, frame beam 6, and frame column 8.

[0045] In this embodiment, the seismic isolation and vibration reduction floor 1 is connected to the frame beam 6 through seismic isolation bearings 2. The oil damper 4 is fixedly connected below the seismic isolation and vibration reduction floor 1 and moves together with the seismic isolation and vibration reduction floor 1 during an earthquake. A viscous damper 3 is horizontally arranged between the oil damper 4 and the frame beam 6. Electrical equipment 7 with different functions is arranged on the seismic isolation and vibration reduction floor slab 1. The frame beam 6 is connected to the base floor or other floors through the frame column 8. An isolation belt is provided between the frame column 8 and the seismic isolation and vibration reduction floor 1, which can effectively weaken the seismic action on the electrical equipment on the floor, thereby reducing the impact of the earthquake on the electrical equipment on the floor, and thus ensuring normal power supply during the earthquake or rapid power restoration after the earthquake.

[0046] In the embodiment of the present invention, by proposing a seismic isolation and vibration reduction floor system suitable for electrical equipment in indoor substations in high-intensity seismic areas, the following beneficial effects can be achieved:

[0047] (1) The seismic isolation and vibration reduction floor is connected to the frame beam through seismic isolation bearings, which not only ensures the transfer of the load of the electrical equipment on the floor to the main frame but also weakens the seismic amplification effect of the main frame.

[0048] (2) By arranging an oil damper below the seismic isolation and vibration reduction floor, the vibration of the seismic isolation and vibration reduction floor can be weakened during an earthquake, and the anti-overturning ability of the seismic isolation and vibration reduction floor can be improved.

[0049] (3) By arranging a viscous damper between the oil damper and the frame beam, the seismic action can be weakened through energy dissipation during an earthquake, and the maximum relative displacement between the seismic isolation and vibration reduction floor and the main frame can be limited, preventing damage to relevant power facilities due to excessive relative displacement of the seismic isolation and vibration reduction floor during an earthquake.

[0050] (4) By arranging isolation belts around the seismic isolation and vibration reduction floor and the frame column and filling them with materials with relatively large flexibility, a certain degree of relative movement space between the seismic isolation and vibration reduction floor and the main frame during an earthquake is provided, without affecting normal use in peacetime.

[0051] (5) The seismic isolation and vibration reduction floor can be prefabricated in a factory, which can enhance practicality.
