[0002] Power towers are very important components in the power transmission system, mainly used to support and suspend transmission lines to ensure that electricity can be transmitted safely and stably to various regions. Common types of power towers include angle steel towers, steel pipe towers, etc. Angle steel towers are assembled from angle steel and have a relatively stable structure, while steel pipe towers usually have better wind resistance.

[0003] Power towers can support transmission lines to maintain a certain height and spacing in the air, reduce mutual interference between lines, and improve transmission efficiency. Power towers can adapt to complex terrains, cross various complex terrains such as mountains, rivers, and valleys, enabling power transmission to be unrestricted by geographical conditions. When there is a height difference, by adjusting the height of the support base, the tower can stand steadily, avoiding tilting or collapsing of the tower due to terrain reasons.

[0004] When installing the existing support device for power towers, when there is a height difference, the height of the moving plate is usually adjusted by rotating the threaded rod so that the moving plate moves to the position of the screw hole, facilitating the alignment of the bolts on the support device with the screw holes on the power tower. However, only rotating the threaded rod easily causes the threaded rod to wear faster and is time-consuming and laborious. For this reason, an adjustable-height power tower support device is proposed to solve the above problems. Content of the Utility Model

A first mounting seat 8 is slidably connected to the inner wall of the upper end of the fixed seat 2. The first mounting seat 8 provides support for the rotation of the support plate 7. A support plate 7 is rotatably connected to the inner wall of the upper end of the first mounting seat 8. The support plate 7, the moving plate 5, and the base 1 are arranged in a triangle, making the support device more stable. The outer wall of the rear end of the support plate 7 is rotatably connected to the inner wall of the front end of the second mounting seat 6. A threaded rod 12 penetrates and is threadedly connected to the inner wall of the front end of the moving block 11. The outer wall of the rear end of the threaded rod 12 is rotatably connected to the inner wall of the front end of the first mounting seat 8. By rotating the threaded rod 12, the movement of the first mounting seat 8 is driven. An adjusting component is arranged on the outer wall of the upper end of the base 1. The adjusting component is used to adjust the height.

[0031] Referring to Figure 1 and Figure 3 , the adjusting component includes vertical plates 3. There are two vertical plates 3, and the two vertical plates 3 are symmetrically arranged. The vertical plates 3 provide support for the sliding of the moving plate 5. The outer wall of the bottom end of the vertical plates 3 is fixedly connected to the outer wall of the upper end of the base 1. A moving plate 5 is slidably connected to the inner wall of the left end of the vertical plates 3. The moving plate 5 is arranged in a T shape.

[0033] Working principle: The base 1 is fixed at the required position through the positioning holes and positioning screws around the base 1. The limit on the moving block 11 is released by moving the insert block 9. Moving the moving block 11 drives the first mounting seat 8 to slide on the inner wall at the upper end of the fixed seat 2. By releasing the insert block 9 and clamping it on the inner wall at the upper end of the fixed seat 2 to fix the position of the moving block 11, a rough adjustment of the position of the first mounting seat 8 can be achieved. Subsequently, by rotating the threaded rod 12 to drive the first mounting seat 8 to move, a fine adjustment of the position of the first mounting seat 8 is carried out. The moving plate 5 is T-shaped and slides on the inner wall at the left end of the vertical plate 3. When the angle of the support plate 7 changes, it will push or pull the moving plate 5 to slide on the vertical plate 3, thereby realizing the height adjustment of the entire support device. The power tower is fixed by installing the positioning screws on the moving plate 5.
