[0018] 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 of the embodiments.

[0019] Example 1

[0020] Reference Figure 1-3 A lightning protection device for electric power equipment comprises a base 1, which is installed on the electric power equipment that needs lightning protection. A metal cylinder 3 is vertically fixedly connected to the base 1, and the metal cylinder 3 is connected to the grounding wire. A lightning rod 2 is abutted on the metal cylinder 3. A plurality of hinged rods 4 are hinged at equal distances on the lightning rod 2, and a plurality of hinged rods 4 are hinged at the lower ends of the plurality of hinged rods 4. The plurality of hinged rods 4 are hinged to moving blocks 5, and the plurality of moving blocks 5 are moved by a moving mechanism, and the moving blocks 5 are moved to adjust the inclination angles of the plurality of hinged rods 4, so as to adjust the height of the lightning rod 2, thereby adjusting the protection range of the lightning rod, which is beneficial to improving the adaptability of the device. At the same time, since the lightning rod is installed at a higher position, the hinged rod 4 is used to play a supporting role, which is beneficial to the stability of the lightning rod and prevents strong winds from affecting the stability of the lightning rod.

[0021] Through holes are provided on the plurality of moving blocks 5 , and a slide bar 7 is fixedly connected to the base 1 . The slide bar 7 passes through the through holes to limit the moving blocks 5 , which is beneficial to the stability of the moving blocks 5 when moving.

[0022] Example 2

[0023] In Example 1, when adjusting the moving block 5, it is necessary to adjust the multiple moving blocks 5 separately, which makes the operation complicated and cumbersome. Figure 1-3 As another preferred embodiment of the utility model, on the basis of embodiment 1, the moving mechanism includes a gear 6, which is rotatably connected to the metal cylinder 3 through a bearing, and multiple moving blocks 5 are fixedly connected to connecting edges 9, and multiple connecting edges 9 are fixedly connected to racks 8, and multiple racks 8 are meshed with the gear 6. A fixing mechanism is provided on the gear 6. By adopting the design of the gear 6, when rotating, it will drive multiple racks 8 to move simultaneously, thereby driving multiple moving blocks 5 to move simultaneously, which is beneficial to the convenience during operation.

[0024] The fixing mechanism includes a connecting block 11, which is vertically fixedly connected to the gear 6. A fixing bolt 12 is threadedly penetrated on the connecting block 11. A plurality of fixing holes 10 are equidistantly arranged on the circumference of the metal cylinder 3. The fixing bolt 12 is threadedly connected to the fixing hole 10. The fixing bolt 12 is a rust-proof bolt. By fixing the fixing bolt 12 to the fixing holes 10 at different positions, the position of the gear 6 after rotation is fixed, thereby fixing the position of the moving block 5.

[0025] A handle is fixedly connected to the connecting block 11, and the handle is used for easy grasping so as to drive the gear 6 to rotate.

[0026] When in use, by grasping the handle, the gear 6 is driven to rotate, so that the gear 6 drives multiple racks 8 to move simultaneously, thereby driving multiple moving blocks 5 to move, and adjusting the inclination angle of multiple hinged rods 4, and adjusting the height of the lightning rod 2, thereby adjusting the protection range of the lightning rod.

[0027] Example 3

[0028] Reference Figure 4 As another preferred embodiment of the utility model, on the basis of embodiment 1, a mounting groove 13 is opened on the inner wall of the through hole, and a roller 14 is installed in the mounting groove 13. The roller 14 abuts against the slide bar 7. By adopting the design of the roller 14, rolling friction replaces sliding friction, reducing frictional resistance, which is beneficial to the movement of the moving block 4.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
