This method eliminates the need for excavating a foundation pit when fixing the ground anchor, offering good convenience. Furthermore, the use of multiple fixing nails and spiral fixing blades to fix the anchor plate base enhances its practicality.

Description

Technical Field

[0001] This utility model relates to the field of high-voltage transmission line tensioning technology, and more specifically, to a ground anchor device for high-voltage transmission line tensioning. Background Technology

[0002] High-voltage power transmission is a method of transmitting electricity by stepping up the voltage output from generators using transformers at power plants. This method is chosen because, for the same transmission power, higher voltage results in lower current. This reduces the current during transmission, thereby lowering heat loss and material costs associated with long-distance transmission. During high-voltage transmission, power lines are erected on poles. To prevent damage from strong winds, the stability of the pole bases needs to be increased in areas with soft soil. Currently, the main method involves inserting ground anchors into the ground and then connecting them to the utility poles via ropes. The ground anchors are used to pull the utility poles, making them more stable. However, existing ground anchors require pre-dug pits for installation, which is inconvenient. Furthermore, they are only fixed with a single anchor nail, resulting in insufficient stability. After the ground anchor is installed, the utility pole is pulled only by the pull ring and rope on the ground anchor. When the pull ring is under force, it experiences a large lateral tension, affecting the quality of the ground anchor tension. Therefore, we propose a ground anchor device for tensioning high-voltage transmission lines. Utility Model Content
