Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to a modular pumped storage power station support structure. Background Technology

[0002] A pumped-storage power station is an energy storage facility that utilizes water level differences and the principle of power generation via pumps. It pumps water to an upstream reservoir using electricity during off-peak hours and releases the water to generate electricity during peak hours, thereby regulating the load on the power grid and improving the stability and reliability of the power supply. The support structure of a pumped-storage power station is the basic structure used to support and install various equipment. It typically consists of a base plate, main beams, support beams, and seismic isolation mechanisms. Using a pumped-storage power station support structure ensures stable equipment installation, enhances the overall structure's seismic resistance and load-bearing capacity, and improves the safety and durability of the power station. Furthermore, the design of the support structure effectively reduces the impact of external vibrations on the power station equipment, extends the equipment's service life, and ensures the long-term stable operation of the power station in high-intensity working environments.

[0003] A search revealed Chinese patent publication number CN221767402U, which discloses a support for high-voltage equipment in a substation. The support includes a base plate, with a support body fixedly connected to the top of the base plate. A motor is mounted at the center of the top of the base plate, and a threaded rod is fixedly connected to the drive end of the motor. A connecting collar is threaded onto the outer side of the threaded rod, and connecting rods are fixedly connected to both sides of the connecting collar. A connecting frame is fixedly connected to the outer side of each connecting rod. Fixed columns are fixedly connected to the four corners of the bottom of the base plate, and each of the four fixed columns contains a buffer assembly. This invention allows for height adjustment of the connecting frame, enabling fine-tuning after the support is installed to ensure correct installation and operation of the equipment. It is adaptable to different types and sizes of high-voltage equipment and provides buffering at the bottom of the base plate, enhancing the safety of the equipment and support body during earthquakes.

[0004] In existing technologies, some pumped storage power station supports use springs and dampers as vibration reduction mechanisms. While this design can effectively mitigate vibrations, its effectiveness is limited compared to the seismic resistance requirements of modern pumped storage power stations. The vibration reduction capacity of springs and dampers is usually insufficient to cope with strong earthquakes or prolonged vibrations, resulting in insufficient stability of the supports and equipment, thereby affecting the overall operational safety of the power station. Utility Model Content

[0005] The purpose of this application is to provide a modular pumped storage power station support structure, which aims to improve the existing technology where some pumped storage power station supports use springs and dampers as vibration reduction mechanisms, but compared with vibration isolation methods, they cannot meet the current seismic requirements.

[0006] The modular pumped storage power station support provided in this application adopts the following technical solution: A modular pumped storage power station support includes a base plate, a main beam fixedly connected to the top of the base plate, multiple fixed plates fixedly connected to the outside of the main beam and the base plate, multiple support beam structures fixedly connected to the outside of the main beam, a top cover fixedly connected to the top of the main beam, a vibration isolation mechanism fixedly connected to the bottom of the base plate, and a base fixedly connected to the bottom of the vibration isolation mechanism, with the bottom of the base in contact with the ground;

[0007] The vibration isolation mechanism includes multiple connecting plates, which are divided into two groups. One group is fixedly connected to the top of the base, and the other group is fixedly connected to the bottom of the base plate. A limiting shaft is fixedly connected to the adjacent side of the two groups of connecting plates, and a connecting base is fixedly connected to the adjacent side of the two groups of connecting plates. A support shaft is fixedly connected to the adjacent side of the connecting base, and multiple sliding pads are slidably connected to the outside of the support shaft. A guide limiting component is fixedly connected to the adjacent side of the base and the base plate.

[0008] Through the above technical solution, the modular pumped storage power station support structure forms a stable frame through a base plate, main beams, and fixed plates, while the supporting beam structure and top cover complete the overall architecture. In the seismic isolation mechanism, components such as connecting plates and limiting shafts work together to effectively buffer vibrations; the guiding and limiting components ensure sliding stability, reducing the impact of external vibrations on the support structure and improving its stability and the reliability of the power station operation.

[0009] As a further description of the above technical solution: the support beam structure includes multiple splicing blocks, the external parts of the multiple splicing blocks are slidably connected to the inside of the main beam, the outer side of the multiple splicing blocks is fixedly connected to a support beam shell, the inner side of the support beam shell is fixedly connected to a honeycomb inner plate, and the inner side of the support beam shell is fixedly connected to a bolt anti-loosening component.

[0010] The above solutions employ a sliding connection between the support beam structure and the main beam, enabling flexible splicing and length adjustment to suit different installation requirements. The honeycomb inner panel enhances the strength and stability of the support beam shell. The bolt anti-loosening component prevents the connectors from loosening. These multiple designs ensure the stability of the support beam and improve the overall reliability and durability of the modular pumped storage power station support system.

[0011] As a further description of the above technical solution: the guide limiting component includes a top guide block and a bottom guide block. The top of the top guide block is fixedly connected to the bottom of the base plate, and the bottom of the bottom guide block is fixedly connected to the top of the base. Sliding blocks are slidably connected to the outside of the top guide block and the bottom guide block.

[0012] The above-described design involves a top-level guide block connected to the base plate and a bottom-level guide block connected to the foundation, with the two connected by a sliding block. This design precisely guides the base plate to slide smoothly relative to the foundation, ensuring stable movement of the support structure during operation of the seismic isolation mechanism, preventing offset and swaying, and enhancing the seismic performance and structural stability of the modular pumped storage power station support structure.

[0013] As a further description of the above technical solution: the bolt anti-loosening assembly includes a fixing bolt, the fixing bolt being externally slidably connected to the inside of the support beam housing, a buffer pad being externally slidably connected to the fixing bolt, a first anti-slip pad being externally slidably connected to the fixing bolt, a second anti-slip pad being externally slidably connected to the fixing bolt, and a plurality of anti-slip teeth being fixedly connected to the adjacent side of the first anti-slip pad and the second anti-slip pad, the anti-slip teeth being interlocked with each other.

[0014] The above solution involves a bolt anti-loosening component that uses fixed bolts to penetrate the outer shell of the support beam. Combined with buffer pads, it reduces vibration and impact. The anti-slip teeth on the first and second anti-slip pads mesh with each other to form a double anti-loosening structure. This effectively resists high-frequency vibrations during the operation of the pumped storage power station, prevents bolts from loosening, ensures the stability of the support beam structure, and improves the overall safety and reliability of the support system.

[0015] As a further description of the above technical solution: a fixing groove is provided inside the main beam, the outside of the splicing block is slidably connected inside the fixing groove, and the bottom of the top cover is in contact with the top of the splicing block.

[0016] The above solution involves: a fixed groove inside the main beam for the splicing blocks to slide, enabling flexible assembly and position adjustment of the support beam structure to adapt to different module layout requirements; the bottom of the top cover fits into the top of the splicing blocks to form a limiting constraint, enhancing the connection rigidity between the support beam and the main beam, improving the overall stability and deformation resistance of the modular pumped storage power station support, and ensuring structural safety and reliability.

[0017] As a further description of the above technical solution: both the top guide block and the bottom guide block have guide grooves inside, and the sliding block is slidably connected inside the guide grooves.

[0018] The above scheme involves opening guide grooves in the top and bottom guide blocks, allowing the sliding block to slide within the grooves. This provides precise guidance for the sliding of the seismic isolation mechanism, effectively constraining the relative motion trajectory between the base plate and the foundation, preventing deviation or jamming during the seismic isolation process, ensuring the modular pumped storage power station support remains stable under vibration, and improving the seismic isolation effect and structural reliability.

[0019] As a further description of the above technical solution: the fixing plate adopts a right-angle plate design, and a triangular plate is fixedly connected to the center of the fixing plate.

[0020] The above solution employs a design combining right-angle plates and triangular plates for the fixing plate. The right-angle plates provide a stable connection foundation between the base plate and the main beam, while the triangular plates, with their unique geometric stability, effectively enhance the fixing plate's resistance to deformation. The combined effect of these two elements disperses the stress on the support structure, improves the overall strength and stability of the modular pumped storage power station support structure, and ensures the safe operation of the power station.

[0021] As a further description of the above technical solution: both the upper and lower ends of the support shaft are provided with connecting grooves, the outside of the connecting base is slidably connected to the inside of the connecting groove, and the inside of the connecting groove is provided with a cross-shaped sliding groove.

[0022] The above-described design features connecting grooves at the upper and lower ends of the support shaft, allowing the connecting base to slide within these grooves. Furthermore, the cross-shaped sliding grooves within the grooves further regulate the sliding path, ensuring both flexibility and stability in the connection between the connecting base and the support shaft. During operation of the modular pumped storage power station support structure, this design effectively buffers vibrations through the seismic isolation mechanism, prevents component misalignment, and enhances the overall seismic performance and structural reliability of the support structure.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. In this utility model, when vibration occurs, the ground causes the base to slide. When the base slides, under the guidance of the bottom guide block and the sliding block, the support shaft and the sliding pad slide, thereby isolating the connection between the bottom plate and the base, and thus absorbing the impact force generated by the vibration, which greatly improves the shock resistance of the device.

[0025] 2. The support beam structure utilizes the honeycomb design of its internal honeycomb inner panel to enhance its structural strength while reducing its weight. This, combined with the fixing grooves and splicing blocks within the main beam, enables rapid installation, thus improving the device's practicality. The outer shell of the support beam, along with bolt anti-loosening components, reinforces the connection. External buffer pads on the fixing bolts provide necessary cushioning to prevent breakage. Furthermore, the first and second anti-slip pads, coupled with anti-slip teeth, prevent the fixing bolts from loosening, thereby addressing the issue of bolted connections being prone to loosening under dynamic loads.

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0032] Example: A modular pumped storage power station support structure, referring to... Figure 1 , Figure 2 The system includes a base plate 1, which forms the foundation of the support structure and supports the entire structure. A main beam 3 is fixedly connected to the top of the base plate 1. The main beam 3 is the core load-bearing structure of the support system, supporting the top cover 9 and connecting the various support beam structures 7. The main beam 3 is made of high-strength steel, possessing high bending strength and rigidity. Multiple fixing plates 2 are externally fixed to the main beam 3 and the base plate 1. The fixing plates 2 are designed with right angles to secure the connection between the main beam 3 and the base plate 1. A triangular plate is fixedly connected at the center inside, enhancing the stability and strength of the structure and preventing deformation or damage to the fixing plates 2 due to uneven stress. Multiple support beam structures 7 are externally fixed to the main beam 3, and a top cover 9 is fixedly connected to the top of the main beam 3, protecting and enclosing the support system. The top cover 9 restricts the support beam structure 7 to be fixed on the top of the main beam 3 to ensure the stability of the entire structure. The bottom of the base plate 1 is fixedly connected to the vibration isolation mechanism 5, and the bottom of the vibration isolation mechanism 5 is fixedly connected to the base 4. The base 4 is the bottom structure of the support. The base 4 provides a stable foundation for the entire support by combining with the vibration isolation mechanism 5. The bottom of the base 4 is in contact with the ground. The fixing plate 2 adopts a right-angle plate design, and a triangular plate is fixedly connected to the center of the inside of the fixing plate 2.

[0033] Specifically, when constructing the modular pumped storage power station support structure, the base 4 is first placed with its bottom in contact with the ground, and the vibration isolation mechanism 5 is installed on top of the base 4. Next, the bottom of the base plate 1 is fixed to the vibration isolation mechanism 5, and the main beam 3 is fixed to the top of the base plate 1 using a fixing plate 2 with a right-angle plate design and internal triangular plates. Subsequently, multiple support beam structures 7 are installed on the outside of the main beam 3, and finally, the top cover 9 is fixed to the top of the main beam 3, completing the overall support structure construction and providing support for the pumped storage power station.

[0034] The vibration isolation mechanism 5 includes multiple connecting plates 51, which are fixed to the top of the base 4 and the bottom of the base plate 1 respectively, to isolate ground vibration and reduce the impact of external vibration on the support structure. The multiple connecting plates 51 are divided into two groups, one group is fixedly connected to the top of the base 4 and the other group is fixedly connected to the bottom of the base plate 1. A limiting shaft 52 is fixedly connected to the adjacent side of the two groups of connecting plates 51. A connecting base 55 is fixedly connected to the adjacent side of the two groups of connecting plates 51. A support shaft 54 ​​is fixedly connected to the adjacent side of the connecting base 55. Multiple sliding pads 53 are slidably connected to the outside of the support shaft 54. The connecting base 55 and the support shaft 54 ​​are the core components for achieving the vibration isolation effect. Multiple sliding pads 53 are slidably connected to the support shaft 54 ​​to play the role of shock absorption and buffering. A guide limiting component 6 is fixedly connected to the adjacent side of the base 4 and the base plate 1. Connecting grooves are opened at both the upper and lower ends of the support shaft 54. The outside of the connecting base 55 is slidably connected to the inside of the connecting groove. A cross groove is opened inside the connecting groove.

[0035] Specifically, when installing the seismic isolation mechanism 5, first fix the two sets of connecting plates 51 to the top of the base 4 and the bottom of the base plate 1 respectively. Install the upper limit shaft 52 and the connecting base 55 on the side of the two sets of connecting plates 51 that are close to each other. Align the connecting grooves at both ends of the support shaft 54 ​​with the connecting base 55 and insert it. Use the cross-shaped sliding groove in the connecting groove to complete the fit. Put multiple sliding shims 53 on the outside of the support shaft 54. Finally, install the guide and limit assembly 6 on the side of the base 4 and the base plate 1 that are close to each other to complete the assembly of the seismic isolation mechanism 5 and the main body of the bracket.

[0036] The guide and limiting assembly 6 includes a top guide block 61 and a bottom guide block 63. The top of the top guide block 61 is fixedly connected to the bottom of the base plate 1, and the bottom of the bottom guide block 63 is fixedly connected to the top of the base 4. A sliding block 62 is slidably connected to the outside of both the top and bottom guide blocks 61 and 63, allowing the bracket to slide smoothly during installation. The guide groove design ensures smooth movement of the sliding block 62, avoiding component wear and installation difficulties caused by excessive friction. Guide grooves are provided inside both the top and bottom guide blocks 61 and 63, and the sliding block 62 is slidably connected inside these guide grooves.

[0037] Specifically, when installing the guide and limit assembly 6, first fix the top guide block 61 to the bottom of the base plate 1 and the bottom guide block 63 to the top of the base 4. Then, insert sliding blocks 62 sequentially into the guide grooves of the top guide block 61 and the bottom guide block 63, ensuring that the sliding blocks 62 can slide smoothly within the guide grooves. This completes the installation of the guide and limit assembly 6, enabling it to cooperate with the vibration isolation mechanism 5 and assist in the relative sliding operation between the base plate 1 and the base 4.

[0038] Reference Figure 3 , Figure 4 The support beam structure 7 includes multiple splicing blocks 73. The external parts of the multiple splicing blocks 73 are slidably connected to the inside of the main beam 3. The outer side of the multiple splicing blocks 73 is fixedly connected to the support beam shell 71. The inner side of the support beam shell 71 is fixedly connected to the honeycomb inner panel 72. The inner side of the support beam shell 71 is fixedly connected to the bolt anti-loosening component 8. The core function of the bolt anti-loosening component 8 is to prevent the various parts of the support from loosening when connected by bolts, so as to ensure the long-term stability of the structure. The main beam 3 has a fixing groove inside, and the external parts of the splicing blocks 73 are slidably connected to the inside of the fixing groove. The bottom of the top cover 9 is in contact with the top of the splicing blocks 73.

[0039] Specifically, when installing the support beam structure 7, firstly, multiple splicing blocks 73 are slidably embedded into the fixing grooves inside the main beam 3, ensuring that the splicing blocks 73 can move flexibly within the fixing grooves. Then, the support beam outer shell 71 is fixed on the opposite side of the splicing blocks 73, and a honeycomb inner panel 72 is installed inside the support beam outer shell 71. Next, the bolt anti-loosening component 8 is fixed inside the support beam outer shell 71. Finally, the top cover 9 is placed on top of the main beam 3, with its bottom contacting the top of the splicing blocks 73, completing the assembly of the support beam structure 7 and the main beam 3.

[0040] The bolt anti-loosening assembly 8 includes a fixing bolt 81, which is externally slidably connected to the inside of the support beam housing 71. A buffer washer 82 is externally slidably connected to the fixing bolt 81, as are a first anti-slip washer 83 and a second anti-slip washer 85. Multiple anti-slip teeth 84 are fixedly connected to adjacent sides of the first and second anti-slip washer 83 and 85, and these anti-slip teeth 84 are interlocked. The design of multiple anti-slip washer and anti-slip teeth 84 externally slidably connected to the fixing bolt 81, along with the interlocking anti-slip teeth 84 of the first and second anti-slip washer 83 and 85, prevents the bolt from loosening under vibration or impact. The buffer washer 82 absorbs the impact force during installation, protecting the bolt and connecting parts from damage.

[0041] Specifically, when installing the bolt anti-loosening component 8, first pass the fixing bolt 81 through the corresponding hole in the support beam housing 71, then put on the buffer pad 82 and the first anti-slip pad 83 in sequence, ensuring that the anti-slip teeth 84 of the first anti-slip pad 83 face upwards, then put on the second anti-slip pad 85 so that the two sets of anti-slip teeth 84 mesh with each other, and finally tighten the fixing bolt 81 to complete the installation of the component inside the support beam housing 71.

[0042] The implementation principle of this application embodiment is as follows: when vibration occurs, the ground drives the base 4 to slide. When the base 4 slides, under the guidance of the bottom guide block 63 and the sliding block 62, the support shaft 54 ​​and the sliding pad 53 slide, thereby isolating the connection between the bottom plate 1 and the base 4, and thus absorbing the impact force generated by the vibration, so that the shock resistance of the device is greatly improved.

[0043] The specific process of absorbing vibration is as follows: the base 4 drives the connecting plate 51 fixed on the top of the base 4, and the connecting plate 51 drives the connecting bases 55 and 56 fixed on the top of the connecting plate 51 to rotate. 56 serves as the core connection between the connecting base 55 and the connecting plate 51. Then, while the base 4 slides, it drives multiple sliding pads 53 located inside the limiting shaft 52 to slide. Finally, while the bottom connecting plate 51 slides, it reduces the vibration amplitude of the top connecting plate 51, thereby achieving the purpose of vibration isolation.

[0044] During the sliding process of the vibration isolation mechanism 5 following the base 4, the sliding block 62 slides along the bottom guide block 63 fixed on the top of the base 4 and the top guide block 61 fixed on the bottom of the base plate 1. Since the bottom guide block 63 and the sliding block 62 have limited lengths, the purpose of limiting the vibration amplitude is achieved.

[0045] The honeycomb design of the inner honeycomb plate 72 inside the support beam structure 7 and the main beam 3 improves the strength of the support beam structure 7 and the main beam 3 while reducing their weight. Then, the fixing groove and splicing block 73 inside the main beam 3 enable quick installation, thereby improving the practicality of the device. The outer shell 71 of the support beam is used with the bolt anti-loosening component 8 to achieve the purpose of strengthening the connection. The buffer pad 82 outside the fixing bolt 81 provides necessary buffer to prevent the fixing bolt 81 from breaking. The first anti-slip pad 83 and the second anti-slip pad 85 are coupled together through the anti-slip teeth 84 to prevent the fixing bolt 81 from loosening, thereby solving the problem of easy loosening of the bolt connection structure under dynamic load.

[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
