Description

Technical Field

[0001] This invention belongs to the field of power facility protection, specifically relating to a vibration damping and stabilizing device for transmission line towers. Background Technology

[0002] In high-voltage transmission line systems, to improve the stability of transmission towers under dynamic excitations such as wind loads and conductor galloping, it is often necessary to suspend mass blocks inside the towers.

[0003] When the transmission tower begins to sway due to external forces (such as strong winds), the mass block will move in the opposite direction due to inertia, thereby offsetting part of the transmission tower's movement and achieving the effect of stabilizing the structure and reducing vibration.

[0004] Currently, most counterweights are made of high-density materials such as concrete, cast iron, or steel. While these traditional counterweights can provide the required mass, they are large in size and extremely heavy. During transportation and high-altitude installation, they require large hoisting equipment. Due to space constraints inside the power tower, construction is difficult and costly.

[0005] Therefore, we propose a vibration damping and stabilizing device for power transmission towers to solve the above problems. Summary of the Invention

[0006] In response to the problems that traditional counterweights can provide the required mass, but are large in size and extremely heavy, requiring large hoisting equipment for transportation and high-altitude installation, and are difficult and costly to construct due to space constraints inside the transmission tower, this invention provides a vibration damping and stabilizing device for transmission towers.

[0007] The solution adopted by the present invention to solve its technical problem is: a vibration reduction and stabilization device for transmission towers, including a suspension frame, a mass storage container and multiple sets of suspension components, wherein the suspension frame is fixedly installed on the tower body of the transmission tower by multiple sets of tower clamping components; The storage container is located below the suspension frame, and its top is equipped with a medium filling port for filling the storage container with medium. Multiple suspension components are connected between the suspension frame and the storage container, enabling the storage container to swing or shift.

[0008] Preferably, the medium is water.

[0009] Preferably, the medium is metal particles or dry sand.

[0010] Preferably, a filter plate is fixedly installed at the medium filling port.

[0011] Preferably, the side wall of the storage container is provided with an overflow pipe for automatically draining excess water when there is an overabundance of water inside the storage container.

[0012] Preferably, the storage container is equipped with multiple anti-wave plates fixed at intervals, and the anti-wave plates have connecting holes.

[0013] Preferably, a connecting ring is fixedly connected to the outside of the storage container.

[0014] Preferably, the suspension assembly consists of a steel cable and lugs fixed to both ends of the steel cable, with the upper and lower lugs respectively fixed to the bottom of the suspension frame and the top of the connecting ring.

[0015] Preferably, the tower clamp assembly includes a high-strength screw and a high-strength bolt. One end of the high-strength screw passes through a through hole in the suspension frame and extends to the outside of the suspension frame. A U-shaped clamp is fixedly connected to its outer end. Two nuts are threaded onto the high-strength screw, and the two nuts abut against the outer and inner sides of the suspension frame, respectively. The top and bottom walls of the U-shaped clamp are provided with aligned bolt holes, and the high-strength bolts are inserted into the bolt holes to fasten the U-shaped clamp to the main structure of the power transmission tower.

[0016] Preferably, multiple ribs are welded and fixed between the high-strength screw and the U-shaped clamp.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves a counterweight function by filling a storage container with water. The empty storage container is lightweight, which is convenient for transportation and installation. After the storage container is installed and fixed, the medium can be filled by manual water injection or by collecting rainwater from natural conditions. This greatly reduces the labor intensity and equipment dependence of high-altitude operations. It is especially suitable for the limited installation space inside transmission towers and significantly saves construction costs.

[0018] 2. This invention, by installing a wave-damping plate inside the storage container and guiding the flow of the medium through connecting holes, can effectively suppress the violent shaking of the medium inside the container, avoid the impact of medium fluctuations on the shock absorption effect, ensure that the storage container maintains a stable inertial counteracting effect during swinging or displacement, and improve the shock absorption effect.

[0019] 3. By setting up a filter plate, the present invention can prevent impurities from entering the storage container, avoid impurities from clogging the connecting holes, affecting the flow of the medium, and ensure the long-term stable operation of the device.

[0020] 4. The present invention can automatically discharge excess water when too much rainwater is collected through the overflow pipe, avoiding excessive counterweight that could cause the transmission tower to exceed the load limit, ensuring the safe operation of the device and the tower structure, and making the flexible and convenient water injection counterweight method both reliable and safe.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1-2 This invention provides a technical solution for a vibration damping and stabilization device for power transmission towers: Example 1: according to Figure 1 and Figure 2 As shown, it includes a suspension frame 1, a storage container 51, and multiple sets of suspension components. The suspension frame 1 is made of high-strength steel and welded with a cross 2 inside, which can significantly improve the overall structural strength and deformation resistance of the suspension frame 1.

[0025] The suspension frame 1 is fixedly installed on the tower body of the transmission line tower by multiple sets of tower clamping components. In this embodiment, there are four sets of tower clamping components, which are evenly distributed around the suspension frame 1.

[0026] The tower clamp assembly includes a high-strength screw 31 and a high-strength bolt 35. One end of the high-strength screw 31 passes through a through hole in the suspension frame 1 and extends to the outside of the suspension frame 1. A U-shaped clamp 34 is fixedly connected to its outer end. Multiple ribs 33 are welded and fixed between the high-strength screw 31 and the U-shaped clamp 34. The ribs 33 are made of high-strength steel plate, which can effectively improve the connection strength between the high-strength screw 31 and the U-shaped clamp 34 and avoid deformation or breakage at the connection under long-term stress. Two nuts 32 are threaded on the high-strength screw 31. The two nuts 32 abut against the outer and inner sides of the suspension frame 1, respectively. The double nut 32 locking structure achieves a stable connection between the high-strength screw 31 and the suspension frame 1.

[0027] The top and bottom walls of the U-shaped clamp 34 are provided with aligned bolt holes, and high-strength bolts 35 are inserted into the bolt holes to fasten the U-shaped clamp 34 to the main material of the transmission tower. The inner side wall of the U-shaped clamp 34 conforms to the contour design of the main material of the transmission tower to ensure a tight fit and improve the stability of the fixation.

[0028] The mass storage container 51 is located below the suspension frame 1, and its top is provided with a medium filling port for filling the mass storage container 51 with a medium. In this embodiment, the medium is preferably water. Water is widely available and easy to obtain, which can significantly reduce the cost of use. If the application scenario is different, metal particles or dry sand can also be selected as the medium. The counterweight function is achieved by filling the mass storage container 51 with water. The empty mass storage container 51 is lightweight, which is not only convenient for transportation, but also convenient for installation. After the mass storage container 51 is installed and fixed, the medium can be filled by manually injecting water or by collecting rainwater using natural conditions. This greatly reduces the labor intensity and equipment dependence of high-altitude operations, and is especially suitable for the limited installation space inside the transmission tower, which significantly saves construction costs.

[0029] The side wall of the storage container 51 is equipped with an overflow pipe 53. When too much rainwater is collected, the overflow pipe 53 can automatically drain the excess water, avoiding excessive counterweight that could cause the transmission tower to exceed the load limit. This ensures the safe operation of the device and the tower structure, making the flexible and convenient water injection counterweight method both reliable and safe.

[0030] A connecting ring 52 is fixedly connected to the outside of the storage container 51. The connecting ring 52 is made of annular steel plate and is welded and fixed to the outer wall of the storage container 51.

[0031] In this embodiment, there are eight sets of suspension components. The eight sets of suspension components are evenly distributed between the suspension frame 1 and the connecting ring 52. Each set of suspension components consists of a steel cable 42 and lugs 41 fixed at both ends of the steel cable 42. The steel cable 42 is made of high-strength galvanized steel cable 42, which has good tensile strength and corrosion resistance. The upper and lower lugs 41 are respectively fixed to the bottom of the suspension frame 1 and the top of the connecting ring 52, so that the mass storage container 51 can swing or move freely when subjected to force, thereby achieving the shock absorption function.

[0032] In practical use, the vibration damping and stabilizing device for transmission towers of the present invention first raises the suspension frame 1 to a specified height and then attaches the four U-shaped clamps 34 to the outer contour of the main material of the transmission tower. Next, the nuts 32 on the high-strength screws 31 are tightened one by one to achieve a stable connection between the high-strength screws 31 and the suspension frame 1. Then, the high-strength bolts 35 are inserted through the bolt holes on the top and bottom walls of the U-shaped clamps 34 and tightened to ensure that the U-shaped clamps 34 are stably fixed on the main material of the transmission tower. After the suspension frame 1 is fixed and secure, the storage container 51 is placed directly below the suspension frame 1 and an appropriate amount of water is injected according to the design requirements. If the site has rainwater collection conditions, artificial water injection can be temporarily suspended and the container can be gradually filled by natural rainfall to reduce the intensity of high-altitude operations. When the transmission tower is subjected to the external force of wind, it will swing in the opposite direction to offset part of the vibration energy and achieve the function of vibration reduction and stabilization.

[0033] Example 2: Based on Example 1, such as Figure 1 and Figure 2 As shown, the storage container 51 is optimized and the specific improvements are as follows: Multiple anti-surge plates 6 are fixedly installed at intervals inside the mass storage container 51. The anti-surge plates 6 are made of stainless steel and are welded to the inner wall of the mass storage container 51. The anti-surge plates 6 have connecting holes 61. When the mass storage container 51 swings, the anti-surge plates 6 can block the violent shaking of the water. At the same time, the connecting holes 61 can guide the water flow to pass slowly, avoiding additional impact force caused by water fluctuations, and ensuring that the mass storage container 51 maintains a stable inertial counteracting effect during the swinging process.

[0034] A filter plate 54 is fixedly installed at the medium filling port. The filter plate 54 is made of stainless steel and has fine filter holes on its surface with a diameter of no more than 2mm. It can effectively filter impurities such as leaves, prevent impurities from entering the storage container 51, avoid impurities from clogging the connecting hole 61, affect the flow of the medium, and ensure the long-term stable operation of the device.
