Description

Technical Field

[0001] The present invention relates to the technical field of earthquake resistance of building foundations, and more specifically, to an anti-fault buffer device suitable for high-cold, high-altitude and high-seismic intensity conditions. Background Art

[0002] With the rapid development of my country's economy and the acceleration of urbanization, the demand for electricity continues to grow, and the construction of power transmission networks is becoming increasingly important. In particular, with the widespread application of renewable energy (such as wind energy and solar energy), DC transmission technology has attracted attention due to its high efficiency and low loss characteristics in long-distance transmission. The country vigorously promotes ultra-high voltage direct current transmission projects to achieve cross-regional power dispatching and optimal resource allocation to ensure the safety and stability of power supply. However, with the extension of transmission lines, especially in high-cold, high-altitude and high-seismic intensity areas, the design and construction of line foundations face new challenges. The foundation includes the tower foundation. The tower body of the tower is generally called the superstructure, and the part of the tower other than the superstructure is called the foundation.

[0003] Under conditions of high cold, high altitude and high seismic intensity, the existing transmission line foundation design technology has many shortcomings. First, the low temperature environment in high cold areas may cause the embrittlement of traditional materials, affecting the bearing capacity and stability of the foundation. Secondly, the special geological conditions and climate change in high altitude areas make the soil characteristics complex, and traditional foundation design is difficult to adapt. In addition, in areas of high seismic intensity, the existing seismic design is often unable to effectively cope with extreme seismic loads, resulting in foundation misalignment, deformation or failure, thus affecting the safety of power transmission. Therefore, a new type of anti-misalignment buffer technology is urgently needed to improve the adaptability and risk resistance of the foundation under these extreme conditions. Summary of the invention

[0004] In order to overcome the defect of the above-mentioned prior art that it cannot adapt to extreme cold, high altitude and / or high seismic intensity conditions, the present invention provides an anti-fault buffer device suitable for extreme cold, high altitude and high seismic intensity conditions, which can maintain good performance under extreme cold, high altitude and / or high seismic intensity conditions.

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0006] The anti-fault buffer device suitable for high-cold, high-altitude and high-seismic intensity conditions includes a basic frame, connecting components, load-bearing components, and a buffer component for buffering external pressure and seismic energy;

[0007] Among them, the interior of the basic frame is hollow, the load-bearing component and the buffer component are arranged in the basic frame, the first end of the connecting component is located in the basic frame and connected to the load-bearing component, the second end of the connecting component passes through the outside of the basic frame and is connected to the device requiring anti-misalignment buffer outside the anti-misalignment buffer device, one end of the buffer component is connected to the load-bearing component, and the other end is connected to the inner surface of the basic frame.

[0008] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0009] The basic frame is used to protect the components within the basic frame, and the load-bearing components are used to provide support for the devices that require anti-misconnection buffering, thereby enhancing the bearing capacity and stability of the anti-misconnection buffering device. The buffering components are used to buffer the impact force caused by abnormal conditions such as earthquakes, and prevent the anti-misconnection buffering device from misconnecting, deforming or failing. This makes the anti-misconnection buffering device have adaptability and risk resistance under extreme conditions of high cold, high altitude and high earthquake. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The accompanying drawings are only used for illustrative purposes and should not be construed as limiting the present embodiment;

[0016] In order to better illustrate the present embodiment, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product;

[0017] It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0018] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] Example 1

[0020] This embodiment proposes an anti-fault buffer device suitable for high-cold, high-altitude and high-seismic intensity conditions. Figure 1 A schematic cross-sectional structure diagram of the anti-fault buffer device proposed in this embodiment, which is suitable for high-cold, high-altitude and high-seismic intensity conditions; Figure 2 This is a schematic diagram of the structure of the anti-fault buffer device proposed in this embodiment, which is suitable for high-cold, high-altitude and high-seismic intensity conditions;

[0021] The anti-fault buffer device suitable for high-cold, high-altitude and high-seismic intensity conditions proposed in this embodiment includes a basic frame 1, a connecting component 2, a load-bearing component 3, and a buffer component 4 for buffering external pressure and seismic energy;

[0022] Among them, the interior of the basic frame 1 is hollow, the load-bearing component 3 and the buffer component 4 are arranged in the basic frame 1, the first end of the connecting component 2 is located in the basic frame 1 and connected to the load-bearing component 3, the second end of the connecting component 2 passes through the outside of the basic frame 1 and is connected to the device requiring anti-misalignment buffer outside the anti-misalignment buffer device, one end of the buffer component 4 is connected to the load-bearing component 3, and the other end is connected to the inner surface of the basic frame 1.

[0023] During the specific implementation process, the basic frame is used to protect the components within the basic frame, and the load-bearing components are used to provide support for the device that needs to resist misalignment and buffering, thereby enhancing the bearing capacity and stability of the anti-misalignment buffer device, and the buffer components are used to buffer the impact force caused by abnormal conditions such as earthquakes, to prevent the anti-misalignment buffer device from misalignment, deformation or failure, etc., so that the anti-misalignment buffer device has adaptability and risk resistance under extreme conditions of high cold, high altitude and high earthquake.

[0024] In an optional embodiment, the load-bearing component 3 includes a pressure plate 31 and a support rod 32, one plane of the pressure plate 31 is connected to the first end of the connecting component 2, the other plane of the pressure plate 31 is connected to one end of the support rod 32, the other end of the support rod 32 is connected to the inner surface of the base frame 1, and the four side surfaces of the pressure plate 31 are connected to the inner surface of the base frame 1.

[0025] As an exemplary illustration, the number of support rods 32 can be adjusted according to actual needs. In this embodiment, four support rods are selected. From the perspective of construction cost: four support columns may be slightly higher than three, but it is more cost-effective than five, because one more support column will significantly increase the material and construction costs. Four support columns are relatively simpler to construct, especially under complex terrain and conditions. The installation of five columns may require more complex technology and more human resources. The maintenance of four support columns is relatively simple, the number of columns is moderate, the workload of inspection and maintenance is less, and it is not easy to cause maintenance difficulties due to increased complexity. From the perspective of supporting force: four support columns provide a more balanced force distribution, compared with three columns, reducing the risk of a single column bearing excessive load. Under conditions of high cold, high altitude and high seismic intensity, the design of four support columns can effectively disperse seismic stress and improve seismic performance. One more than three support columns provides a certain redundancy and improves the safety of the overall structure. If one of the columns has a problem, the other columns can share more load. Compared with five support columns, the four-column design simplifies the mechanical calculations, ensures the uniform distribution of supporting force without being too complicated, provides better anti-dislocation and buffering effects, and adapts to harsh environmental conditions.

[0026] In an optional embodiment, a plurality of frame rods 5 are further provided in the base frame 1 , and the frame rods 5 are used to support the base frame 1 .

[0027] In an optional embodiment, the anti-disconnection buffer device further includes a buffer pad 6 , and the buffer pad 6 is arranged between the frame rod 5 and the pressure plate 31 .

[0028] As an example, Figure 1 As shown, a plurality of frame rods 5 are arranged in the base frame 1, and the frame rods 5 are divided into two parts. The two ends of the frame rods 5 of the first part are respectively connected to the two side surfaces of the base frame 1, and the two side surfaces are opposite to each other, and the two ends of the frame rods 5 of the second part are respectively connected to the top surface and the bottom surface of the base frame (1); as an exemplary illustration, Figure 1 As shown, the buffer pad 6 is arranged between the frame rod 5 of the first part and the pressure plate 31.

[0029] In an optional embodiment, the pressure plate 31 includes a first sub-pressure plate 311, a second sub-pressure plate 312 and a third sub-pressure plate 313 connected in sequence, the first sub-pressure plate 311 and the third sub-pressure plate 313 are used to bear pressure, and the second sub-pressure plate 312 is used to absorb external force.

[0030] As an example, Figure 3 This is a schematic diagram of the structure of the pressing plate proposed in this embodiment. Figure 3It is shown that the pressing plate 31 includes a first sub-pressing plate 311, a second sub-pressing plate 312 and a third sub-pressing plate 313 which are connected in sequence.

[0031] As an example, Figure 3 As shown, one side of the first sub-pressing plate 311 is connected to the connecting part 2, and the other side is connected to one side of the second sub-pressing plate 312. The other side of the second sub-pressing plate 312 is connected to one side of the third sub-pressing plate 313, and the other side of the third sub-pressing plate 313 is connected to the support rod.

[0032] In an optional embodiment, the material of the first sub-pressing plate 311 and the third sub-pressing plate 313 includes alloy material.

[0033] As an exemplary description, the first sub-pressing plate 311 and the third sub-pressing plate 313 are made of a rigid material. Preferably, the rigid material is an alloy material. Preferably, the rigid material is steel.

[0034] In an optional embodiment, the material of the second sub-pressing plate 312 includes rubber, polyurethane or other elastic composite materials.

[0035] As an exemplary illustration, the second sub-pressing plate 312 is made of a flexible material. Preferably, the flexible material is rubber, polyurethane or other elastic composite materials.

[0036] In this optional embodiment, the purpose of using three layers of buffer pressure plates is to enhance the seismic resistance and anti-fracture ability of the structure. The uppermost and lowermost rigid buffer pressure plates can bear the pressure of the upper structure to ensure the stability and bearing capacity of the structure. The middle flexible buffer pressure plate absorbs and disperses the stress generated by the earthquake, reduces the impact on the overall structure, and improves the seismic performance. Compared with the two-layer buffer pressure plate, the three-layer buffer design can provide an additional buffer, further reduce the impact of the earthquake on the structure, and improve the overall safety and durability. The rigid buffer pressure plate can be made of high-strength steel or other high-strength alloy materials, which can provide sufficient strength and durability. The flexible buffer pressure plate can use rubber, polyurethane or other elastic composite materials to effectively absorb and buffer vibrations and shocks.

[0037] Example 2

[0038] This embodiment proposes an anti-fault buffer device suitable for high-cold, high-altitude and high-seismic intensity conditions, and improves on the anti-fault buffer device suitable for high-cold, high-altitude and high-seismic intensity conditions proposed in Embodiment 1.

[0039] The anti-fault buffer device suitable for high-cold, high-altitude and high-seismic intensity conditions proposed in this embodiment includes a basic frame 1, a connecting component 2, a load-bearing component 3, and a buffer component 4 for buffering external pressure and seismic energy;

[0040] Among them, the interior of the basic frame 1 is hollow, the load-bearing component 3 and the buffer component 4 are arranged in the basic frame 1, the first end of the connecting component 2 is located in the basic frame 1 and connected to the load-bearing component 3, the second end of the connecting component 2 passes through the outside of the basic frame 1 and is connected to the device requiring anti-misalignment buffer outside the anti-misalignment buffer device, one end of the buffer component 4 is connected to the load-bearing component 3, and the other end is connected to the inner surface of the basic frame 1.

[0041] During the specific implementation process, the basic frame is used to protect the components within the basic frame, and the load-bearing components are used to provide support for the device that needs to resist misalignment and buffering, thereby enhancing the bearing capacity and stability of the anti-misalignment buffer device, and the buffer components are used to buffer the impact force caused by abnormal conditions such as earthquakes, to prevent the anti-misalignment buffer device from misalignment, deformation or failure, etc., so that the anti-misalignment buffer device has adaptability and risk resistance under extreme conditions of high cold, high altitude and high earthquake.

[0042] In an optional embodiment, the load-bearing component 3 includes a pressure plate 31 and a support rod 32, one plane of the pressure plate 31 is connected to the first end of the connecting component 2, the other plane of the pressure plate 31 is connected to one end of the support rod 32, the other end of the support rod 32 is connected to the inner surface of the base frame 1, and the four side surfaces of the pressure plate 31 are connected to the inner surface of the base frame 1.

[0043] In an optional embodiment, the buffer assembly 4 includes a first spring 41 and / or a second spring 42;

[0044] When the buffer assembly 4 includes a first spring 41, the support rod 32 is connected to the inner surface of the base frame 1 through the first spring 41;

[0045] When the buffer assembly 4 includes a second spring 42, the total number of the second springs 42 is greater than or equal to 1, and the second spring 42 is used to connect the side of the support rod 32 and the inner surface side of the base frame 1. If the number of the support rods 32 is greater than 1, the second spring 42 is also used to connect the support rods 32 and the support rods 32 together.

[0046] As an exemplary illustration, when the buffer assembly 4 includes the second spring 42 , the buffer assembly 4 also includes a connecting bolt 43 , and the connecting bolt 43 is used to fix the second spring 42 .

[0047] As an exemplary explanation, under normal stress state, the first spring 41 and the second spring 42 are both in a non-deformed state. When the external environment suddenly changes and an abnormal external force is applied to the device, the first spring 41 and the second spring 42 are deformed to generate resistance to buffer the abnormal external force, so as to prevent the abnormal external force from impacting the anti-misbreak buffer device, thereby preventing the device from misbreak, deformation or failure. For example, when the second spring 42 is Figure 1 When the connection is generally horizontal, if an earthquake occurs, the second spring 42 can effectively offset the earthquake force in the horizontal direction.

[0053] The key points of this embodiment include the design of a special anti-fault structure, combined with high-performance buffer materials, which effectively absorbs the impact of seismic waves and enhances the stability and safety of the foundation. In addition, this embodiment also covers the selection of materials adapted to extreme climates and construction and maintenance methods in high-altitude areas to ensure the reliability and durability of infrastructure in harsh environments. These innovations together constitute comprehensive protection for this embodiment, aiming to improve the operating safety of DC lines under extreme conditions.

[0054] It can be understood that the anti-fault buffer device of this embodiment improves the method of embodiment 1, and the options in the above embodiment 1 are also applicable to this embodiment, so they are not described repeatedly here.

[0055] Example 3

[0056] Based on Example 1 and Example 2, this embodiment proposes an anti-fault buffer device suitable for high-cold, high-altitude and high-seismic intensity conditions, and proposes a specific implementation example.

[0057] In this embodiment, the base 21 is a cup mouth base, the first spring 41 is called a buffer spring, the second spring 42 is called a sliding assembly, and the pressure plate 31 is called a top pressure plate.

[0058] The overall structure of the device proposed in this embodiment includes a base frame, a buffer spring, a support rod, a sliding assembly, a top pressure plate, a seismic filler and a connecting bolt. The design of each part has its own unique function to ensure the safety and stability of the system. The base frame is the core skeleton of the entire device and is made of high-strength weather-resistant materials. This material can provide excellent durability and stability under high-cold, high-altitude and high-seismic intensity environmental conditions. The top pressure plate is composed of two seismic-resistant materials. The design of the frame is to enhance its resistance to fracture under extreme climatic conditions, especially under high vibration and external force impact. The buffer spring is installed under the support rod and is one of the key components of the device. They are designed to absorb and mitigate external impact and seismic energy, reducing the risk of vibration transmitted to the upper structure. The material and design of the spring are strictly selected to ensure that it can provide sufficient support when it is impacted and adapt to certain deformation, thereby reducing the possibility of structural damage. The support rod plays the role of connecting and transferring loads to ensure the stability between the buffer spring and the top pressure plate. The sliding assembly allows the support structure to be slightly adjusted when it is stressed to adapt to the deformation caused by external forces and reduce the risk of overall structural fracture. This design improves the flexibility and stability of the system under external impact. The top pressure plate is tightly connected to the outer shell by bolts to further disperse the pressure from the outside. The design of the pressure plate can not only resist fatigue loss caused by high vibration, but also remain stable under long-term high-pressure conditions. The seismic-damping filler is directly connected to the superstructure through prefabricated solid piers. The seismic-damping filler surrounds the superstructure. The seismic-damping filler has multiple characteristics such as compressibility, vibration resistance, and compactness. Taking into account the stress conditions of the superstructure, the distribution of the seismic-damping filler on the vertical section is also a trapezoidal distribution with larger top and smaller bottom, such as Figure 1 shown.

[0059] The connecting bolts ensure the tight connection between the components, preventing the risk of breakage caused by long-term stretching or extrusion. In addition, all core components are made of low-temperature resistant and anti-corrosion materials to protect the internal structure from erosion by the harsh environment. The selection of these materials can not only adapt to extreme climates, but also maintain good mechanical properties in high-cold and high-altitude areas. In short, the device effectively solves the problem of fracture and failure of traditional foundations under extreme conditions through sophisticated mechanical design and material selection. It significantly enhances the seismic and impact resistance of the DC line foundation, ensuring the safe and long-term stable operation of the power transmission system in complex environments.

[0060] The present invention first optimizes the design of the foundation structure and adopts a multi-level, multi-material combination foundation form to enhance its bearing capacity and anti-dislocation performance. The foundation design takes into account the special geological conditions of high-cold, high-altitude and high-seismic intensity areas to ensure that the foundation can effectively disperse and transfer loads and reduce lateral vibrations caused by earthquakes or other dynamic loads. The present invention includes two main parts: a pillar structure (load-bearing component) and a buffer system (buffer component). The pillar structure is all reinforced to withstand the harsh conditions of high-cold and high-altitude environments. A spring system is installed at the bottom of each pillar, which can be used to absorb and alleviate vibrations and impact forces caused by seismic activity. This spring configuration helps prevent excessive movement and damage to the foundation structure during an earthquake, and avoids the risk of dislocation of the upper structure, which leads to an interruption of the power system.

[0061] In terms of material selection, the present invention uses materials with excellent low-temperature performance and high-strength characteristics, such as modified polymers, special synthetic rubbers and high-strength composite materials. These materials can still maintain good elasticity and toughness in low-temperature environments, avoiding structural failure due to embrittlement. At the same time, the lightweight characteristics of the material also help to reduce the deadweight of the foundation and improve the overall stability. In addition, the foundations are connected by reinforced transverse connecting rods, which enhances the lateral stability of the overall structure, which is very important for resisting the lateral forces generated in earthquakes. This design not only improves the seismic performance of the foundation, but also effectively disperses and transmits seismic forces, reduces stress concentration at a single point, and improves the overall fracture resistance of the system.

[0062] The present invention introduces a novel anti-disconnection buffer system, which includes an elastic buffer layer (buffer component). The elastic buffer layer is arranged between the foundation and the ground, which can effectively absorb ground vibration energy and reduce the influence of lateral vibration.

[0063] In summary, the present invention provides a DC line foundation anti-fault buffer device suitable for high-cold, high-altitude and high-seismic intensity conditions, aiming to solve the problems of the existing technology in terms of the fragility and insufficient earthquake resistance of the foundation structure in extreme environments. The device significantly improves the foundation's anti-fault capability and overall stability by optimizing the foundation design, selecting new materials, and introducing advanced shock absorption and buffering mechanisms; it significantly improves the foundation's anti-fault capability by optimizing the design, innovating materials, and using advanced shock absorption mechanisms, providing a strong guarantee for the safe operation of the power transmission network in special environments. This technology has broad application prospects and provides innovative solutions for the development of future power infrastructure.
