[0001] The utility model relates to the technical field of power transmission iron towers, in particular to a ground wire bracket of a power transmission iron tower. Background Art

[0002] Power transmission tower ground wire supports are devices used to support and secure the ground wire (also known as the lightning conductor) in power transmission lines. In power systems, ground wires are primarily used to protect transmission lines from overvoltages such as lightning strikes, ensuring their safe operation.

[0003] In existing technical practices, ground wire brackets typically use bolts and nuts as fixing elements to anchor the ground wires directly to the bracket structure. However, due to the lack of effective organization and sorting mechanisms, the ground wires are arranged in a chaotic manner, which not only affects the overall aesthetics and structural integrity, but also brings inconvenience to subsequent maintenance and upkeep, increasing the time cost and labor intensity of the operation.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-Figure 3 A ground wire support for a power transmission tower comprises two main frames 1, each of which is fixedly connected to a common top plate 2. The arrangement of this common top plate 2 ensures the stability and reliability of the overall structure. Multiple I-shaped supports 3 are arranged on the top surface of top plate 2, arranged in pairs. The purpose of this symmetrical arrangement is to ensure balanced force distribution. Plates 4 are provided on opposite sides of the two I-shaped supports 3 in the same pair, and a limit plate 11 is provided at the bottom of each plate 4. This limit plate 11 facilitates the individual removal and assembly of each plate 4.

[0022] The I-shaped seat 3 is provided with a limiting structure for limiting the plate body 4 and the limiting plate 11 , and the plate body 4 is provided with a wire harness structure for limiting the wire harness.

[0023] The wiring harness structure includes an arc-shaped base 5 fixedly connected to the top of the plate 4. A screw 6 is rotatably connected to the top curved surface of the arc-shaped base 5. A slide rod 7 is fixedly connected to the top curved surface of the arc-shaped base 5. The slide rod 7 is provided to ensure that the arc-shaped top seat 8 can move vertically stably along the axis of the screw 6 and relative to the arc-shaped base 5. The arc-shaped top seat 8 is threadedly connected to the screw 6, and the arc-shaped top seat 8 and the slide rod 7 are vertically slidably connected. The arc-shaped top seat 8 and the arc-shaped base 5 are relatively limited and fixed to the ground wire.

[0024] The arc-shaped top seat 8 and the arc-shaped base 5 are arranged correspondingly, thereby ensuring the stable position limitation of the ground wire.

[0025] The limiting structure includes a sliding slot 9 on the I-shaped seat 3, which is adapted to fit within a limiting plate 11. The limiting plate 11 slides horizontally within the sliding slot 9. The I-shaped seat 3 is provided with a pair of sockets 10, and a slot 12 is formed at the top of the limiting plate 11. A rod 13 slides vertically within the sockets 10. The rod 13 is vertically connected to the socket 10 and then inserted into the slot 12. The top of the rod 13 is fixedly connected to an upper plate 15. A spring 17 is sleeved around the rod 13, and its ends are fixedly connected to the I-shaped seat 3 and upper plate 15, respectively. The rod 13 is reset and removed from the slot 12 by pulling on the spring 17.

[0026] The I-shaped seat 3 is provided with an auxiliary part for limiting the position of the plate body 4 separately.

[0027] The auxiliary component includes a second rod 14 that slides vertically with the socket 10. The top of the second rod 14 is fixedly connected to the second upper plate 16. A second spring 18 is mounted on the second rod 14, and the two ends of the second spring 18 are fixedly connected to the I-beam 3 and the second upper plate 16 respectively. A limit slot is formed on the top of the plate body 4 to match the second rod 14. By pulling the second spring 18, the second rod 14 is moved away from and inserted into the limit slot.

[0028] I-shaped seat 3 and top plate 2 are threadedly connected with bolt 19. The provision of bolt 19 is convenient for disassembling and assembling I-shaped seat 3 and for its maintenance and care.

[0029] The functional principle of this utility model can be explained through the following operation modes:

[0030] Place the ground wire on top of the arc base 5 and ensure that it is in the correct position. Tighten the bolt 19 to move the arc top seat 8 downward along the axis of the screw 6 to compress the ground wire. The function of the slide bar 7 is to ensure that the arc top seat 8 can move stably and vertically.

[0031] When it is necessary to select a different arc base 5 according to the actual ground line, the upper plate 16 is pulled vertically, the spring 18 is pulled, and the insertion rod 14 is away from the limiting groove, thereby removing the arc base 5 and the arc top seat 8 together.

[0032] When the limiting plate 11 needs to be disassembled, maintained and serviced, after removing the arc base 5, the upper plate 15 is pulled vertically upward to drive the insertion rod 13 away from the slot 12, and then the limiting plate 11 is removed horizontally.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
