Description

Technical Field

[0001] The present invention relates to the technical field of wind resistance of transmission towers, in particular to an anti-wind resistance device capable of dynamically adjusting the force applied to angle steel rods of transmission towers. Background Art

[0002] Transmission towers, critical load-bearing structures in power transmission networks, are often constructed in open, wild areas. These locations offer abundant wind resources, but this also means that transmission tower structures are subject to significant wind loads year-round. Wind, especially transient strong winds and eddy currents, is the primary culprit for structural fatigue, vibration, and even instability and collapse. Therefore, improving the wind resistance of transmission towers to ensure structural stability in adverse weather conditions is crucial.

[0003] To improve the wind resistance of transmission towers, the industry has implemented a variety of measures. One approach involves manually enhancing their structural strength by optimizing the tower structure and increasing the cross-section of the rods. However, this approach often results in a significant increase in steel usage, which in turn drives up construction costs. Furthermore, its effectiveness in combating sudden, unsteady strong winds remains limited.

[0004] On the other hand, some transmission towers introduce auxiliary vibration reduction or reinforcement devices. For example, mechanical or hydraulic dampers are installed to dissipate the energy of wind-induced vibrations. However, these damping devices usually have some inherent problems. Their damping parameters are fixed after installation, which means they are designed for a specific vibration frequency or wind force level. Faced with the ever-changing and irregular wind in reality, this "unchanging" damping strategy seems somewhat powerless. When the wind is weak, it may not be effectively excited and play no role in vibration reduction; and when encountering instantaneous strong winds far exceeding the design value, it may not be able to effectively absorb the impact energy due to insufficient damping force, and may even be damaged.

[0005] Furthermore, traditional wind-resistant structural designs employ a fixed force transmission path. This means that no matter the angle or force of the wind, the impact force is always transmitted along a predetermined path, ultimately converging at specific nodes on the tower. The problem with this design approach is that it leads to stress concentration. Over time, these nodes and members, subjected to repetitive, impactful loads, are prone to metal fatigue and cumulative damage. Summary of the Invention

[0026] The tensioning mechanism 8 is mounted on the upper surface of the base 1 and is used to stabilize the tower body; the tensioning mechanism 8 includes a support block 802 and a limit frame 805.

The tensioning rope 11 is limited by the first limiting wheel 806 and the second limiting wheel 807, so that the tensioning rope 11 forms an angle with the power tower 2, thereby improving the traction effect.

[0027] A vibration-isolating mechanism 9 is mounted on the upper surface of the tensioning mechanism 8 to eliminate vibration. The vibration-isolating mechanism 9 is relatively fast, comprising a second connecting rod 901, the outer wall of which is fixedly connected to the limiting frame 805, the outer wall of which is rotatably connected to a second limiting rod 902, one end of which is fixedly connected to a limiting block 903, the outer wall of which is fixedly connected to a vibration-isolating block 904, the inner portion of which is slidably connected to the outer wall of the tensioning rope 11; Specifically, the angle of the limit block 903 is adjusted by rotating the second limit rod 902, and the tensioning rope 11 is passed through the limit block 903. When the tensioning rope 11 is shaken by the wind, the limit block 903 is driven to shake and the vibration-absorbing block 904 is caused to swing, thereby consuming the shaking force and reducing the shaking of the tensioning rope 11.

[0028] The inner wall of the power tower 2 is symmetrically fixedly connected with a connecting plate 13, and the inner wall of the power tower 2 is symmetrically fixedly connected with a second supporting plate 14.

The damping coefficient is adjusted by the control box 12 to cause the first electromagnetic damper 403 to contract to consume the force, thereby reducing the influence of the instantaneous impact force of the wind on the angle steel rod frame 3 and the power tower 2. The second motor 803 is started to drive the winding wheel 804 to wind up the tensioning rope 11, so that the tensioning rope 11 slides on the first limiting wheel 806 and the second limiting wheel 807. One end of the tensioning rope 11 is fixed to the traction plate 15, so that the tensioning rope 11 is tightened, thereby maintaining the stability of the power tower 2 when there is wind. The tensioning rope 11 is limited by the first limiting wheel 806 and the second limiting wheel 807, so that the tensioning rope 11 forms an angle with the power tower 2. The angle of the limiting block 903 is adjusted by rotating the second limiting rod 902, and the tensioning rope 11 is passed through the limiting block 903. When the tensioning rope 11 is shaken by the wind, the limiting block 903 is driven to shake and the vibration-damping block 904 is swung, thereby consuming the shaking force and reducing the shaking of the tensioning rope 11.
