Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line foundations, and in particular to a modular foundation of a power transmission tower with multi-dimensional energy consumption functions and an energy consumption method thereof. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Since transmission towers are usually located in open areas, they are easily affected by wind, especially under extreme weather conditions such as typhoons and strong winds. Wind vibration effects may cause structural damage or even collapse of transmission towers.

[0004] At present, the most common wind-vibration-resistant measure for transmission towers is to install tuned mass dampers (TMDs) to adjust the natural frequency of the structure and reduce the displacement caused by wind vibration. TMDs are often installed on the top or crossarms of transmission towers because these parts are most affected by wind vibration and TMDs can absorb and dissipate vibration energy more effectively.

[0005] But at the same time, it also brings many problems: first, TMD will increase the weight of the top of the transmission tower, which may affect the stability of the structure, especially in high wind speeds or earthquakes; second, the top of the tower is usually difficult to access, and the installation, inspection and maintenance of TMD are difficult and costly; third, it has high requirements for frequency tuning and may not work.

[0006] The development of prefabricated foundations is of great necessity. First, prefabricated foundations can significantly improve construction efficiency. Through factory-based production of prefabricated components, the on-site construction period can be greatly shortened, and rapid construction can be achieved. This is of great significance for accelerating the process of urbanization and alleviating labor shortages and cost increases in the construction industry. Secondly, the environmental friendliness of prefabricated foundations is reflected in the reduction of on-site waste generation, which meets the requirements of green buildings and sustainable development and helps achieve the energy-saving and environmental protection goals of the construction industry.

[0007] However, due to the large aspect ratio of tall structures such as transmission towers, it is difficult to effectively implement prefabricated foundations using traditional technologies, and there is little research on prefabricated foundations in terms of vibration reduction and seismic resistance of transmission towers at this stage. Summary of the invention

[0008] In order to solve the above problems, the present invention proposes a modular foundation of a transmission tower with multi-dimensional energy dissipation function and an energy dissipation method thereof, which ensures that the transmission tower foundation is easy to transport and install, while improving the earthquake resistance and wind vibration resistance of the transmission tower foundation, assisting the transmission tower line to dissipate wind vibration energy, and reducing the damage to the transmission tower caused by vibration, thereby solving the problems of the current lack of research on assembled foundations of transmission towers, poor structural forms, and long-term vibration influence on transmission lines.

[0018] As an optional implementation, the top of the step module is provided with a bolt hole, and the bolt hole is used to pass the anchor bolt; the bottom of the column is designed with a large foot, and the column and the step module are connected by the anchor bolt.

[0019] As an optional implementation, the elastic ropes in different directions in the energy dissipation middle layer are gathered into a bundle and then extended to the energy dissipation lower layer.

[0020] As an optional implementation, the sliding of the slider drives the mass block to move in the shear thickening liquid, the mass block shears the shear thickening liquid, the shear thickening liquid becomes thicker, and then the vibration energy is dissipated through friction between the mass block and the shear thickening liquid.

[0021] As an optional implementation, the elastic cord is vibrated to pull the elastic cord retracting and releasing device, thereby driving the rotation of the turntable, thereby enhancing the collision between the balls and dissipating the vibration energy.

[0030] The present invention proposes a modular foundation for a transmission tower with multi-dimensional energy dissipation functions, aiming to solve the problems of little research on prefabricated foundations of transmission towers, poor structural forms and long-term vibration influence on transmission lines at the current stage. On the one hand, while ensuring that the prefabricated foundation is easy to transport, construct and install, the division of modules is conducive to improving the integrity of the foundation and facilitating earthquake resistance; on the other hand, by setting up energy dissipation and vibration reduction modules, energy dissipation is assisted by dissipating the vibration response transmitted to the bottom of the tower, thereby reducing the influence of vibration.

[0031] In view of the fact that transmission towers are susceptible to vibration under the action of wind, the modular foundation of the transmission tower of the present invention is designed with a vibration reduction module with a multi-level energy dissipation mechanism. The vibration reduction module is composed of a multi-layer structure that works together to quickly respond to and dissipate vibration energy caused by natural phenomena such as wind and earthquakes, reduce the impact on the upper structure, significantly improve the stability and safety of the transmission tower, and effectively reduce the potential damage of vibration to the structure.

The uniqueness of this design lies in its adaptability, which can adapt to various complex terrains and environmental conditions. At the same time, its multi-level energy dissipation mechanism dissipates vibration energy through physical principles, reduces the impact on the superstructure, and improves the stability and economic efficiency of the entire power transmission system.

[0033] The present invention proposes a modular design of the transmission tower foundation, which realizes rapid construction and efficient transportation through factory-produced prefabricated components, speeds up the construction progress, and reduces the impact of on-site construction on the environment. The integrity and seismic resistance of the transmission tower foundation are strengthened by prestressed steel strands and anchor bolts.

[0052] In this embodiment, the base plate 1 includes a convex plate 11 and a concave plate 12. The base plate 1 is composed of the convex plate 11 and the concave plate 12 spliced ​​end to end. A limiting block 13 is provided on the convex plate 11, and a limiting groove 14 is provided on the concave plate 12 to facilitate precise alignment during construction.

[0053] As an optional implementation, the base plate 1 is configured to be four pieces, two convex plates 11 and two concave plates 12 , which are precisely aligned and spliced ​​by the limiting blocks 13 and the limiting grooves 14 , and the hollow portion formed is used to place the step module 2 .

[0054] As an optional embodiment, a prestressed hole 23 is provided on the base plate 1, and a prestressed steel strand 4 passes through the prestressed hole 23, which is used to apply prestress to the base plate 1 through the prestressed steel strand 4 for splicing.

[0055] In this embodiment, a prestressed hole 23 is provided at the bottom of the step module 2, and a prestressed steel strand 4 passes through the prestressed hole 23 to connect the bottom plate 1 and the step module 2;

[0056] Connecting blocks 5 are provided on four surfaces of the connection between the bottom plate 1 and the step module 2, and the connection between the bottom plate 1 and the step module 2 is strengthened by connecting bolts 6;

[0057] When connecting the base plate 1 and the step module 2, prestress is applied to the base plate 1 through the prestressed steel strands 4, and the connecting bolts 6 are tightened at the same time to enhance the stability of the overall structure.

[0058] As an optional embodiment, the connecting block 5 is an angle steel, and the prestress applied by the prestressed steel strands 4 and the pre-tightening force of the connecting bolts 6 strengthen the connection between the base plate 1 and the step module 2, so that the foundation has a stronger integrity and improves the earthquake resistance.

[0059] In this embodiment, a bolt hole 214 is provided at the top of the step module 2, and the bolt hole 214 is used to pass the anchor bolt 7; the bottom of the column 3 is designed with a large foot, and the column 3 and the step module 2 are connected by the anchor bolt 7 to ensure the rigidity of the connection.

[0060] In this embodiment, the base plate 1, the step module 2 and the column 3 are all prefabricated in the factory. The base plate 1 is prestressed on site by prestressed steel strands 4, and the base plate 1 and the step module 2 are connected by connecting bolts 6, and the step module 2 and the column 3 are connected by anchor bolts 7, thereby forming an integral structure.

[0061] Specifically, first, the convex plate 11 and the concave plate 12 are spliced ​​together to form a hollow part for placing the step module 2; then, prestress is applied to the base plate 1 through the prestressed steel strands 4, and the connecting bolts 6 are tightened at the same time to enhance the stability of the overall structure; finally, the column 3 is placed in the step module 2, and the column 3 is connected to the step module 2 using the anchor bolts 7 to ensure the rigidity of the connection.

[0062] In this embodiment, if Figure 3-Figure 5 As shown, the vibration reduction module 21 includes an energy-absorbing top layer, an energy-absorbing middle layer and an energy-absorbing lower layer, which work together to dissipate vibration energy caused by external factors such as wind.

[0063] In this embodiment, if Figure 3 and Figure 4As shown, the energy dissipation top layer includes a ball 2111, a rotating disk 2112, an elastic cord retracting device 2114 and an elastic cord 2113;

[0064] The ball 2111 is placed on the rotating disk 2112, and the collision between the ball 2111 and the rotating disk 2112 is used to dissipate energy;

[0065] The elastic cord retracting device 2114 is placed on a support under the center of the rotating disk 2112;

[0066] The elastic rope 2113 penetrates through the three-layer structure of the energy-absorbing top layer, the energy-absorbing middle layer and the energy-absorbing lower layer of the vibration reduction module 21 . In the energy-absorbing top layer, the elastic rope 2113 is wound around the elastic rope retracting and releasing device 2114 .

[0067] When vibration occurs, the collision of the ball 2111 and the rotation of the turntable 2112 excite the vibration of the elastic rope 2113, and the elastic rope retracting device 2114 responds and dissipates energy; that is, the elastic rope retracting device 2114 continuously applies a pulling force on the elastic rope 2113, thereby ensuring that the elastic rope 2113 can reciprocate and continue to consume energy.

[0068] As an optional implementation, the elastic rope 2113 is made of carbon fiber material.

[0069] As an optional implementation, the elastic rope retracting and releasing device 2114 is driven by hydraulic power.

[0070] In this embodiment, if Figure 3 and Figure 5 As shown, the energy dissipation middle layer includes an annular rack 2121 and a spiral pair 2122, as well as a housing 2124 filled with a viscous damping fluid 2123 and a blade 2125;

[0071] The housing 2124 is filled with a viscous damping fluid 2123, the paddles 2125 are disposed inside the housing 2124, and a pair of paddles 2125 are disposed opposite to each other inside the housing 2124;

[0072] The spiral pair 2122 is arranged at the center of the blade 2125;

[0073] In the energy dissipation middle layer, the elastic rope 2113 passes through the middle position of the outer shell 2124 and the center position of the blade 2125, and a ring rack 2121 is provided on the outer side of the elastic rope 2113 between a pair of blades 2125;

[0074] The elastic ropes 2113 in four directions are gathered into a bundle at the support and extended to the energy dissipation lower layer.

[0075] The vibration of the elastic rope 2113 on the top energy-absorbing layer is transmitted to the middle energy-absorbing layer, and the vibration of the elastic rope 2113 drives the linear motion of the annular rack 2121, thereby driving the spiral pair 2122 at the center of the blade 2125 to move, thereby driving the rotation of the blade 2125. Through the coordinated action of the annular rack 2121 and the spiral pair 2122, the linear motion of the elastic rope 2113 is converted into the rotational motion of the blade 2125, and the blade 2125 cuts the viscous damping fluid 2123 for further energy consumption.

[0076] In this embodiment, if Figure 3 As shown, the energy dissipation lower layer includes a slider 2131, a mass block 2132, a shell 2133 and a shear thickening liquid 2134;

[0077] The housing 2133 is disposed on the slider 2131 , a mass block 2132 is disposed in the housing 2133 , and the housing 2133 is filled with a shear thickening liquid 2134 ;

[0078] The elastic rope 2113 of this embodiment passes through the three-layer structure of the vibration reduction module 21; wherein, in the energy-absorbing top layer, the elastic rope 2113 is wound around the elastic rope retracting and releasing device 2114; in the energy-absorbing middle layer, the elastic rope 2113 passes through the middle position of the shell 2124 and the center position of the blade 2125, and a ring rack 2121 is provided on the outer side of the elastic rope 2113 between a pair of blades 2125, and the elastic ropes 2113 in four directions are gathered into a bundle and extended to the energy-absorbing lower layer;

[0079] When the vibration energy is transferred to the energy dissipating lower layer, the mass block 2132 moves in the shear thickening fluid 2134, further dissipating the energy through physical friction;

[0080] The slider 2131 is connected to the elastic rope 2113. The sliding movement of the slider 2131 pulls the elastic rope 2113 at the same time, forming a closed loop of energy dissipation, thereby enhancing the energy dissipation effect of the entire vibration reduction module.

[0081] As an optional implementation, the shell 2133 is an anti-collision shell.

[0082] In this embodiment, the vibration reduction module adopts physical principles to dissipate vibration energy through a multi-level energy dissipation mechanism, thereby reducing the impact on the superstructure and improving the stability and economic efficiency of the power transmission system.

[0083] Specifically:

[0084] First, the vibration causes the ball 2111 to collide and the bottom slider 2131 to slide, and the mass block 2132 shears the shear thickening liquid 2134, and the shear thickening liquid 2134 becomes thicker, and then the energy is dissipated through the friction between the mass block 2132 and the shear thickening liquid 2134;

[0085] At the same time, the movement of the slider 2131 pulls the elastic rope 2113, so that the annular rack 2121 moves linearly along the tube wall, thereby driving the spiral pair 2122 at the center of the blade 2125 to move, thereby converting the linear motion into the rotation of the blade 2125, and the blade 2125 cuts the viscous damping fluid 2123 to consume energy;

[0086] At the same time, the elastic rope 2113 pulls the elastic rope taking-up and releasing device 2114, driving the turntable 2112 to rotate, and the turntable 2112 moves the balls 2111, further enhancing the collision between the balls 2111 and dissipating the vibration energy; when the vibration is transmitted to this point and dissipated, only a small amount of vibration energy will be transmitted back to the upper structure. After the vibration ends, the elastic rope taking-up and releasing device 2114 retracts the elastic rope 2113 and pulls the slider 2131 to the initial position.

[0087] In this embodiment, a rubber pad layer 22 is arranged outside the vibration reduction module 21 to further isolate the vibration and prevent further transmission of vibration. The rubber pad layer 22 is a steel plate rubber composite structure. When the tower body is affected by wind and generates wind vibration, it will be transmitted downward. When it reaches the vibration reduction module 21, the rubber pad layer 22 prevents the vibration from being further transmitted downward, and at the same time dissipates the vibration energy to reduce the re-transmission of vibration.

[0088] This embodiment proposes a modular foundation for a transmission tower with a multi-dimensional energy dissipation function, aiming to solve the difficulties in the construction of the transmission tower foundation in complex terrain areas and the problem of how to improve the seismic performance of the structure. The vibration reduction module with a multi-level energy dissipation mechanism is designed to dissipate vibration energy through physical principles, which can efficiently dissipate vibrations caused by natural phenomena such as wind and earthquakes, reduce the impact on the upper structure, and significantly improve the stability and safety of the transmission tower; at the same time, the modular design allows for rapid construction and efficient transportation, speeds up the construction progress, reduces the impact of on-site construction on the environment, improves the durability and long-term stability of the transmission tower, reduces long-term operating costs, and adapts to various complex terrains and environmental conditions.

[0089] Example 2

[0090] This embodiment provides an energy dissipation method for a transmission tower modular foundation with multi-dimensional energy dissipation function as described in Embodiment 1, including:

[0091] The prestressed steel strands 4 are used to apply prestress to the base plate 1, and the base plate 1 and the step module 2 are connected by the connecting bolts 6, and the step module 2 and the column 3 are connected by the anchor bolts 7 to form the overall structure of the modular foundation of the transmission tower;

[0092] The vibration causes the ball 2111 to collide and the slider 2131 to slide. The sliding of the slider 2131 drives the mass block 2132 to move in the shear thickening liquid 2134. The mass block 2132 shears the shear thickening liquid 2134, and the shear thickening liquid 2134 becomes thicker. Then, the energy is dissipated through the friction between the mass block 2132 and the shear thickening liquid 2134.

[0093] The sliding of the slider 2131 pulls the elastic rope 2113, thereby driving the annular rack 2121 to move linearly along the pipe wall, and then driving the action of the spiral pair 2122, thereby converting the linear motion into the rotation of the blade 2125, and the blade 2125 cuts the viscous damping fluid 2123 to consume energy;

[0094] The elastic rope 2113 pulls the elastic rope retracting device 2114, driving the turntable 2112 to rotate, and the turntable 2112 moves the balls 2111, further enhancing the collision between the balls 2111 and dissipating the vibration energy;

[0095] At the same time, the collision of the ball 2111 and the rotation of the turntable 2112 also stimulate the vibration of the elastic rope 2113, and the elastic rope retracting device 2114 continuously applies a pulling force on the elastic rope 2113, thereby driving the reciprocating motion of the elastic rope 2113 to consume energy;

[0096] After the vibration ends, the elastic cord retracting device 2114 retracts the elastic cord 2113 and pulls the slider 2131 to the initial position.

[0097] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
