Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric wire wind resistance, especially to power transmission line wind resistance reinforcing device. BACKGROUND

[0002] Under strong wind conditions, power transmission lines can suffer severe physical damage, including tower collapse, conductor breakage or collision between cables, etc. These accidents not only directly lead to large-scale power outages, but also pose a threat to the life safety of maintenance personnel, increasing the time and cost of restoring power supply. Therefore, improving the wind resistance of power transmission lines is crucial to ensuring the stable operation of the power system.

[0003] After searching, the existing technology has the following aspects of research on power transmission line wind resistance reinforcing device:

[0004] 1. After searching, the authorized utility model patent, announcement number CN210858195U, is an anti-wind and anti-falling electric pole, which includes a pole body, a protection mechanism and a reinforcing mechanism. The protection mechanism includes a connecting section, which is segmented and connected to the outer surface of the pole body. The bottom end of the connecting section is fixedly connected with a connecting section clamping block, and the top end of the connecting section is provided with a connecting section clamping groove. The connecting section clamping block and the connecting section clamping groove are matched and clamped. Through the design of the connecting section, the outer surface of the pole body can be protected, which not only reduces the erosion of the pole body by rainwater, but also provides buffering and fixation when the pole body is impacted in windy weather. In addition, the head-to-tail splicing design of the connecting section makes it more convenient to install, disassemble and replace the connecting section, so that the damaged connecting section can be replaced when it is damaged in a collision. Through the design of the connecting piece and the threaded shaft, the head-to-tail connection between the connecting sections can be easily achieved.

[0005] 2. After searching, the authorized utility model patent, announcement number CN221761559U, is a power distribution line electric pole structure. The power distribution line electric pole structure includes a base that can be buried in the ground. The base is provided with a sinking prevention assembly at the bottom. A support column is provided at the upper end of the base. A support assembly that can be connected with the ground is detachably provided outside the support column. An electric pole is provided on the support column. A stay rope clamp that can be connected with an externally provided stay rope is provided at the upper part of the electric pole. A lightning rod is provided inside the electric pole along the length direction of the electric pole. The upper end of the lightning rod extends to the outside of the upper end of the electric pole. The lower end of the lightning rod extends to the outside of the bottom of the sinking prevention assembly through the support column and the inside of the base. The utility model can effectively prevent the electric pole from sinking, which is conducive to improving the wind pressure performance of the electric pole and can play a role in preventing inclination and reinforcing support.

[0006] The prior art contributes to the improvement of the wind-resistant reinforcing device for power transmission lines and proposes different solutions to related problems, but according to the practical experience and summary of the inventor, the wind-resistant reinforcing device for power transmission lines still has the following problems that can be improved by seeking technical solutions during use in harsh environments:

[0007] Based on the above patent (CN210858195U), the design of the connecting section facilitates the protection of the outer surface of the utility pole body, which not only reduces the rain erosion of the utility pole body, but also provides cushioning and fixation when the utility pole body is impacted in windy weather or when the utility pole body is impacted. In addition, the end-to-end splicing design of the connecting section makes it more convenient to install, disassemble and replace the connecting section, so that the damaged connecting section can be easily replaced when it is damaged in a collision. The design of the connecting piece and the threaded shaft facilitates the end-to-end connection between the connecting sections, and the design of the threaded shaft slot facilitates the placement of the threaded shaft inside the connecting piece, avoiding rain erosion of the threaded shaft. The design of the knob facilitates the rotation of the threaded shaft on the outside, but in this patent, in strong winds and other harsh weather conditions, although the sinking of the utility pole can be prevented to some extent by the utility pole body, the fixed column portion of the utility pole and the utility pole body is fixed to the ground through the chassis, and the force borne by the fixed column portion is large, which can easily damage the utility pole and cause the utility pole to tilt, and in some installation conditions that require the use of a stay wire, it is not suitable.

[0008] Based on the above patent (CN208573927U), the base is embedded in the concrete ground to provide a certain fixing effect, the anti-sinking assembly at the bottom of the base can prevent the base from sinking to some extent, and the base and the pole can be kept in a vertical state. In addition, according to the actual situation, when the pole needs to be constructed at a certain inclination angle, the base and the anti-sinking assembly can be embedded with the support assembly to provide additional support between the ground surface and the support column, which can further prevent tilting and reinforce the support of the pole. The support assembly can also provide a certain stabilizing effect when the pole is normally erected. The stay wire clamp and the external stay wire are connected together to enhance the balance and improve the wind pressure resistance of the pole. The lightning rod provided on the pole can conduct current from the bottom to the ground when struck by lightning to facilitate direct discharge and prevent lightning. Therefore, the utility model of a power distribution line utility pole structure can effectively prevent the pole from sinking, improve the wind pressure resistance of the pole, and prevent tilting and reinforcement support, but in this patent, when installing the cable transmission line, it is not convenient to adjust the height according to the installation requirements of the electric wire environment. The height of the power transmission line in different environments is different, and the fixed installation height cannot meet the needs of all scenarios, resulting in a significant reduction in the installation effect of the device in some situations.
