DETAILED DESCRIPTION
[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0021] The utility model embodiment provides a seismic-resistant substation architecture, such as Figure 1-4 As shown, the earthquake-resistant substation architecture includes: a framework base 1, on the top of which a plurality of mounting blocks 2 are symmetrically fixedly installed; a first slide bar 3, which is fixedly installed on the corresponding mounting block 2; a first spring 4, which is sleeved on the first slide bar 3; a sleeve block 5, which is sleeved on the first slide bar 3; a first damping block 6, which is sleeved on the first slide bar 3, and one side of the first damping block 6 is in contact with one end of the first spring 4; an assembly shell 7, which is fixedly installed on the sleeve block 5; an isolation layer 8, which is arranged on the assembly shell 7; an assembly plate 9 for carrying and installing a small substation body 10, which is fixedly installed on the top of the isolation layer 8; a buffer mechanism for longitudinal earthquake-resistant buffering, which is arranged in the assembly shell 7.
[0022] It should be noted that most small substations currently still use the traditional fixed installation method, that is, directly fixing them on the concrete base. Although this installation method is simple to construct, relatively low in cost, and can remain stable in daily operation, its limitations are exposed when facing natural disasters such as earthquakes. Specifically, when an earthquake occurs, the ground will produce strong vibrations, which will be directly transmitted to the substation fixed on the concrete base. Due to the lack of sufficient buffering and seismic isolation measures between the substation and the base, the main structure and internal equipment of the substation will be subject to strong impact and shaking. Such impact and shaking may not only cause the equipment connection to loosen or fall off, but may also damage the components inside the equipment, and even cause safety accidents such as electrical failures and fires. In addition, due to the uncertainty of the intensity and duration of earthquakes, traditional fixed installation methods are difficult to effectively cope with earthquake disasters of different levels. Under the influence of strong earthquakes, substations may not be able to withstand the violent vibration of the foundation and may suffer serious consequences such as overall tilt and collapse, resulting in the interruption of the operation of the entire power system and causing huge losses to social and economic development. Therefore, in order to solve the vulnerability of current small substations to natural disasters such as earthquakes and improve the seismic resistance and safety of power systems, it is particularly important to develop a new substation architecture with seismic resistance.
[0023] In this embodiment, the frame base 1 serves as the basis of the entire frame, and the mounting block 2 is symmetrically fixedly installed on the top of the frame base 1 for supporting and fixing subsequent components; the symmetrical installation ensures the stability and balance of the structure and provides a solid foundation for the seismic resistance of subsequent components; the first slide bar 3 is fixedly installed on the mounting block 2, the sleeve block 5 and the first damping block 6 are both sleeved on the slide bar, and the first spring 4 is sleeved on the slide bar and in contact with the first damping block 6. This design forms an elastic damping mechanism; during an earthquake, the first spring 4 and the first damping block 6 can absorb and reduce the impact force of the seismic waves on the substation through elastic deformation and damping, thereby protecting the substation body and its internal equipment from damage; the assembly shell 7 is fixedly mounted on the sleeve block 5, and the seismic isolation layer 8 is arranged on the assembly shell 7; the seismic isolation layer 8 can effectively isolate the direct impact of seismic waves on the substation body, and the assembly shell 7 provides a solid shell protection, thereby enhancing the seismic performance of the overall structure; the assembly plate 9 is fixedly mounted on the top of the seismic isolation layer 8, and is used to carry and install the small substation body 10; the design of the assembly plate 9 enables the substation body to be stably installed on the seismic isolation layer while maintaining relative independence from the foundation structure, further reducing the impact of the earthquake on the substation body; the buffer mechanism is arranged in the assembly shell 7, for realizing longitudinal seismic buffering; the buffer mechanism can provide additional longitudinal seismic resistance during an earthquake, further reduce the longitudinal impact of seismic waves on the substation, and improve the seismic stability of the substation.
[0024] In a further preferred embodiment of the utility model, the buffer mechanism includes: a plurality of second sliding rods 11 symmetrically fixedly installed in the assembly shell 7; a plurality of sets of second springs 12 sleeved on the corresponding second sliding rods 11; a plurality of sets of second damping blocks 13 sleeved on the corresponding second sliding rods 11, one side of the corresponding second damping block 13 contacts one end of the corresponding second spring 12; a plurality of sets of brackets 14 sleeved on the corresponding second sliding rods 11; a groove block 15 sleeved on the top end of the bracket 14, and the top end of the groove block 15 is fixedly connected to the seismic isolation layer 8.
[0025] In this embodiment, the second slide bar 11 is symmetrically fixedly installed in the assembly shell 7, providing stable support and sliding tracks for other components; the symmetrical installation ensures the balance and stability of the structure, and the design of the slide bar enables the relevant components to slide along it during an earthquake to achieve a buffering effect; the second spring 12 and the second damping block 13 are both sleeved on the second slide bar 11, and one side of the second damping block 13 is in contact with one end of the second spring 12. This combination forms a longitudinal elastic damping system; when an earthquake occurs, the second spring 12 can undergo elastic deformation to absorb the energy generated by the earthquake, while the second damping block 13 reduces the transmission of vibration through damping; the two work together to significantly improve the longitudinal seismic resistance of the substation; the design of the bracket 14 makes the entire buffer mechanism more stable, able to maintain the integrity of the structure during an earthquake, and at the same time ensure the realization of the buffering effect; the groove block 15 is sleeved on the top of the bracket 14 and fixedly connected to the seismic isolation layer 8. This design allows the buffer mechanism to be tightly connected to the seismic isolation layer to form a whole; through the connection of the groove block 15, the buffer mechanism can effectively transfer the impact force generated by the earthquake wave to the seismic isolation layer, further reducing the impact of the earthquake on the main body of the substation. At the same time, this tight connection also enhances the stability and seismic resistance of the entire structure.
[0026] In a further preferred embodiment of the present invention, a bolt 16 for limiting the position of the bracket 14 is disposed on the groove block 15 , and the bolt 16 passes through the bracket 14 through a thread.
[0027] In this embodiment, the bolt 16 is arranged on the groove block 15 and is threaded through the bracket 14 to limit the bracket 14; through the tightening action of the bolt 16, the bracket 14 can be more stably fixed on the groove block 15, thereby enhancing the stability of the entire buffer mechanism. This design can effectively prevent the bracket 14 from loosening or shifting when an earthquake occurs, ensuring that the buffer mechanism can continue to function. At the same time, the adjustability of the bolt 16 also makes the installation and removal of the bracket 14 more convenient, which is convenient for subsequent maintenance and replacement.
[0028] In a further preferred embodiment of the utility model, a guide groove 17 is provided on the top of the frame seat 1, and the guide groove 17 is adapted to the sleeve block 5. A ball is embedded on the bottom end of the sleeve block 5, and the ball contacts the bottom inner wall of the guide groove 17.
[0029] In this embodiment, the guide groove 17 is provided at the top of the frame seat 1, and is adapted to the sleeve block 5. This means that the sleeve block 5 can slide or move in the guide groove 17; the guide groove 17 provides a clear movement path for the sleeve block 5, ensuring that it can move in a predetermined direction when an earthquake occurs, rather than shaking randomly; this design improves the stability and controllability of the entire structure, and helps to reduce the impact of earthquakes on the substation; the introduction of the ball greatly reduces the friction resistance of the sleeve block 5 when it moves in the guide groove 17. When an earthquake occurs, the sleeve block 5 can slide more smoothly along the guide groove, thereby more effectively absorbing and dispersing earthquake energy. This design not only improves the seismic performance, but also extends the service life of the structure and reduces the wear caused by friction.
[0030] In a further preferred embodiment of the utility model, a shielding shell 19 for shielding rainwater is fixedly mounted on the assembly plate 9, and a drainage pipe 18 is fixedly connected to the assembly shell 7.
[0031] In this embodiment, in an outdoor environment, the substation is often attacked by rainwater. The design of the shielding shell 19 can effectively reduce the rainwater from falling into the assembly shell 7, thereby extending the service life of the components inside the assembly shell 7; the drainage pipe 18 is fixedly connected to the assembly shell 7 and is used to drain the accumulated water inside the assembly shell 7; in rainy weather, a certain amount of rainwater may accumulate inside the assembly shell 7. Through the design of the drainage pipe 18, the accumulated water can be smoothly discharged, thereby preventing the accumulated water from damaging the internal structure and equipment of the assembly shell 7.
[0032] In a further preferred embodiment of the utility model, a plurality of embedded columns are symmetrically fixedly installed on the bottom of the frame base 1, and a limiting plate is fixedly installed on the bottom end of the embedded column, and reinforcing ribs are arranged on the limiting plate.
[0033] In this embodiment, the bottom structure of the frame base 1 is significantly strengthened through the combined design of embedded columns, limit plates and reinforcing ribs. This design makes the entire earthquake-resistant substation structure have better stability and load-bearing capacity when facing natural disasters such as earthquakes, and can effectively resist external impacts and protect the safe operation of the substation.
[0034] In a further preferred embodiment of the utility model, a limit block is fixedly installed on the top end of the second slide rod 11 , and a water-blocking shell for protecting the second damping block 13 is fixedly installed in the assembly shell 7 .
[0035] In this embodiment, the limit block is fixedly installed at the top end of the second slide bar 11, and is used to limit the movement range of related components (such as the second damping block 13) on the second slide bar; under the action of an earthquake or other external force, the limit block can prevent the second damping block 13 from sliding off the second slide bar 11 or moving excessively; this ensures the stability and reliability of the entire buffer mechanism, and avoids performance degradation or damage caused by component displacement; the water-blocking shell is fixedly installed in the assembly shell 7, and its main function is to protect the second damping block 13 from moisture erosion.
[0036] In summary, the earthquake-resistant substation architecture provided by this technical solution effectively improves the earthquake resistance of small substations by combining multiple earthquake-resistant technologies such as seismic isolation, damping and buffering. When an earthquake occurs, this architecture can significantly reduce the impact and damage of seismic waves on the substation, ensure the stable operation of the power system, reduce the occurrence of safety accidents, and provide reliable power guarantee for social and economic development.
[0037] Compared with the related art, the stability and balance of the entire structure are ensured by symmetrically installed components such as the mounting block 2 and the second slide bar 3; this design enables the structure to maintain structural integrity and reduce the risk of deformation and damage when facing external forces such as earthquakes; by setting an elastic damping system (including springs and damping blocks) on the first slide bar 3 and the second slide bar 11, as well as a seismic isolation layer, a multi-level seismic buffering effect is achieved. These components can work together during an earthquake to absorb and disperse seismic energy, significantly reducing the impact on the small substation body 10, avoiding equipment damage, operation interruption, and causing more serious safety accidents.
