Description
Technical Field
[0001] The utility model relates to the technical field of electric power engineering, and particularly relates to a lightning protection overhead line for electric power engineering. Background Technique
[0002] An overhead line is a transmission line that uses insulators to fix transmission conductors on poles standing upright on the ground to transmit electric energy. It consists of conductors, overhead ground wires, insulator strings, poles, grounding devices, etc.
[0003] In the existing lightning protection overhead line for electric power engineering, the installation process of the fixing structure on the pole body is relatively troublesome and the installation speed is slow, resulting in low work efficiency. Moreover, when the current overhead wire body is installed in the wire guiding cylinder, it is not in a completely fitting state with the cylinder wall. Therefore, the overhead wire body may move or shake randomly in the wire cylinder due to external factors, and long-term shaking may pose a safety hazard. Therefore, we introduce a new lightning protection overhead line for electric power engineering. Content of the Utility Model

[0012] Preferably, the wire routing device includes a wire routing cylinder. A fixing block is arranged at the left part of the inner surface of the wire routing cylinder. A first clamping plate is fixedly installed at one end of the fixing block close to the overhead wire body.

[0013] By adopting the above technical solution: By utilizing the cooperation of the threaded rod and the movable sleeve, the position of the second clamping plate can be adjusted through the rotary knob, facilitating the fixing of the overhead wire body. The lightning arrester can provide effective lightning protection for the overhead wire body.

[0015] By adopting the above technical solution: Ensure that the overhead wire body is firmly clamped in the wire routing cylinder, reducing the shaking and displacement of the overhead wire body.
[0016] Preferably, the wire routing cylinder is located between the insulator and the lightning arrester.

[0029] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0030] A lightning protection overhead line for electric power engineering, including a pole body 1. A fixing device 2 is movably installed on the upper part of the outer surface of the pole body 1. Fixing frames 3 are arranged on the left part and the right part of the outer surface of the fixing device 2. Insulators 4 are arranged in front of and behind the middle of the upper ends of the two fixing frames 3. A wire routing device 5 is fixedly installed at the upper end of each of the four insulators 4. Connecting plates 6 are arranged at the front ends of the two fixing frames 3. First fixing holes 7 are arranged at the right ends of the two connecting plates 6. A first screw rod 8 is movably installed between the two first fixing holes 7. First nuts 9 are threadedly installed on the left part and the right part of the outer surface of the first screw rod 8. An overhead wire body 10 is arranged between the two wire routing devices 5 corresponding to the front and back.
[0031] In this embodiment, the fixing device 2 includes a first fixing clip 21. The right end of the first fixing clip 21 is movably installed with a second fixing clip 22 through a hinge. Rubber pads 23 are arranged on the inner surfaces of the first fixing clip 21 and the second fixing clip 22. Fixing plates 24 are arranged at the lower ends of the first fixing clip 21 and the second fixing clip 22. Second fixing holes 25 are arranged at one ends of the two fixing plates 24. A second screw rod 26 is movably installed between the two second fixing holes 25. Left and right parts of the outer surface of the second screw rod 26 are both provided with second nuts 27; both the first fixing clip 21 and the second fixing clip 22 are closely attached to the upper part of the outer surface of the rod body 1 through the rubber pads 23; the first fixing clip 21, the second fixing clip 22 and the two fixing frames 3 are fixedly connected to the rod body 1 through the first screw rod 8 and the second screw rod 26.
[0032] Through the above solution: First, open the first fixing clip 21 and the second fixing clip 22 through the hinge, and put the opened first fixing clip 21 and the second fixing clip 22 on the upper part of the outer surface of the rod body 1. Since the rubber pads 23 are arranged on the inner surfaces of the first fixing clip 21 and the second fixing clip 22, at this time, the rubber pads 23 are closely attached to the outer surface of the rod body 1, increasing the friction and stability, and at the same time protecting the surface of the rod body 1. Then, align the second fixing holes 25 on the two fixing plates 24, pass the second screw rod 26 through the rod body 1 and the two second fixing holes 25, and screw on and tighten the second nuts 27 on the left and right parts of the outer surface of the second screw rod 26, so that the first fixing clip 21 and the second fixing clip 22 are firmly fixed on the rod body 1. Pass the first screw rod 8 through the corresponding two first fixing holes 7, and screw on and tighten the nuts at both ends of the first screw rod 8, so as to realize the fixed connection with the rod body 1.
[0033] In this embodiment, the wire routing device 5 includes a wire routing cylinder 51. A fixing block 52 is arranged at the left part of the inner surface of the wire routing cylinder 51. A first clamping plate 53 is fixedly installed at one end of the fixing block 52 close to the overhead wire body 10. A threaded rod 54 is inserted and threadedly installed at the right part of the outer surface of the wire routing cylinder 51. A second clamping plate 55 is movably installed at one end of the threaded rod 54 close to the first clamping plate 53 through a movable sleeve. A rotary knob 56 is arranged at a point on the threaded rod 54 far from the second clamping plate 55. A lightning arrester 57 is arranged at the upper part of the outer surface of the wire routing cylinder 51 through a fixing seat; the inner surfaces of the first clamping plate 53 and the second clamping plate 55 are both closely attached to the outer surface of the overhead wire body 10; the wire routing cylinder 51 is located between the insulator 4 and the lightning arrester 57.
[0034] Through the above solution: First, place the overhead wire body 10 into the wire routing cylinder 51. The first clamping plate 53 fixedly installed on the fixed block 52 at the left part of the inner surface of the wire routing cylinder 51 plays a preliminary supporting and positioning role for the overhead wire body 10. The operator rotates the rotary knob 56 to drive the threaded rod 54 to rotate until the inner surfaces of the first clamping plate 53 and the second clamping plate 55 are both in close contact with the outer surface of the overhead wire body 10, firmly clamping the overhead wire body 10 in the wire routing cylinder 51. The lightning arrester 57 plays a lightning protection role for the overhead wire body 10 in the wire routing cylinder 51. Since the wire routing cylinder 51 is located between the insulator 4 and the lightning arrester 57, when the overhead wire body 10 transmits current, the insulator 4 first plays an insulating support role, and then the wire routing cylinder 51 guides and fixes the wire body. When there is a lightning overvoltage, the lightning arrester 57 promptly plays a lightning protection role.
[0035] It should be noted that the present utility model is a lightning protection overhead line for a power project. During use, first, open the first fixing clip 21 and the second fixing clip 22 through the hinge, and put the opened first fixing clip 21 and the second fixing clip 22 on the upper part of the outer surface of the rod body 1, so that the rubber pad 23 is in close contact with the outer surface of the rod body 1, increasing the friction and stability, and at the same time protecting the surface of the rod body 1. At this time, the second fixing holes 25 on the two fixing plates 24 are aligned, and the second screw rod 26 is passed through the corresponding holes on the rod body 1 and the two second fixing holes 25, and the second nuts 27 are screwed on the left outer surface and the right outer surface of the second screw rod 26 and tightened, so that the first fixing clip 21 and the second fixing clip 22 are firmly fixed on the rod body 1. The first screw rod 8 is passed through the corresponding two first fixing holes 7, and nuts are screwed on both ends of the first screw rod 8 and tightened, thereby realizing the secondary fixing with the rod body 1, making the overall fixing more stable. The overhead wire body 10 is passed through the two longitudinal wire routing cylinders 51, and the outer surface of the wire routing cylinder 51 is in contact with the two first clamping plates 53. The operator rotates the rotary knob 56 to drive the threaded rod 54 to rotate until the inner surfaces of the first clamping plate 53 and the second clamping plate 55 are both in close contact with the outer surface of the overhead wire body 10, so as to conveniently clamp the overhead wire body 10 firmly in the wire routing cylinder 51, ensuring that the overhead wire body 10 is firmly clamped in the wire routing cylinder 51 and preventing the problems of shaking and displacement of the overhead wire body 10 caused by the outside. When the overhead wire body 10 transmits current, the insulator 4 first plays an insulating support role. When there is a lightning overvoltage, the lightning arrester 57 promptly plays a lightning protection role.
