[0054] This application discloses a lightning protection device for OPGW power distribution lines.

[0055] Please see Figure 1 An embodiment of a lightning protection device and its usage method for an OPGW power distribution line provided in this application includes:

[0056] The composite insulator skirt 2 is located on the lower side of the cable 1, the lightning rod 4 is fixedly installed on the upper side of the surface of the composite insulator skirt 2, the lightning conductor rod 6 cooperates with the lightning rod 4, and the connecting mechanism 5 is located at the bottom of the composite insulator skirt 2.

[0057] The connecting mechanism 5 includes an adjusting component 51. The adjusting component 51 includes an insulating porcelain base 511 fixedly connected to the bottom end of the composite insulator skirt 2. A U-shaped guide rail 512 is fixedly connected to the side surface of the insulating porcelain base 511. An end seat 513 is movably connected to the inner side of the U-shaped guide rail 512, and slots 514 are provided on both sides of the inner wall of the U-shaped guide rail 512. Two retaining edges 515 are provided on both sides of the surface of the end seat 513. The two retaining edges 515 are slidably connected to the slots 514 on the same side, and the connection between the retaining edges 515 and the slots 514 can be locked. The lightning rod 6 is fixedly connected to the end seat 513. In use, simply unlock the connection between the retaining plate and the slots 514, and then adjust the gap between the lightning rod 6 and the lightning conductor 4 by pushing the end seat 513. After adjustment, lock the connection between the retaining plate and the slots 514. This method has better adjustment efficiency compared to the traditional method of continuously turning the adjusting component.

[0058] The above is Embodiment 1 of a lightning protection device for an OPGW distribution line provided in this application. The following is Embodiment 2 of a lightning protection device for an OPGW distribution line provided in this application. Please refer to the following for details. Figures 1 to 6 .

[0059] Based on the solution of Embodiment 1 above:

[0060] Furthermore, a circular groove 516 is formed on the side surface of the end seat 513, and a rotating core 517 is rotatably connected inside the circular groove 516. A slot 518 is formed at the outer end of the rotating core 517, and a notch 519 is formed at the end edge of the rotating core 517. A roller 5110 is rotatably connected inside the notch 519. Part of the wheel edge of the roller 5110 is located inside the slot 518, and a torsion spring 5111 is embedded at the connection between the roller 5110 and the notch 519. A latch 5112 is fixedly connected to the surface of the roller 5110. A groove 5113 is formed at the opening of the circular groove 516 to cooperate with the latch 5112. An insulating operating rod 5114 that cooperates with the roller 5110 is movably inserted into the slot 518. A latch groove 5115 that cooperates with the latch 5112 is formed on the surface of the insulating operating rod 5114. Insert the insulating operating rod 5114 into the slot 518. When the insulating operating rod 5114 is inserted into the slot 518, it drives the roller 5110 to rotate accordingly, so that the latch 5112 on the roller 5110 rotates out from the groove 5113 until the latch 5112 engages in the latch groove 5115 on the surface of the insulating operating rod 5114. At this time, the rotating core 517 unlocks in the circular groove 516 and can be rotated.

[0061] The side surface of the end seat 513 has a through groove 5116 that connects to the circular groove 516, and a sliding tongue 5117 is slidably connected inside the through groove 5116. The surface of the rotating core 517 has an annular tooth groove 5118, and the surface of the sliding tongue 5117 has a tooth surface 5119 that meshes with the annular tooth groove 5118. The outer end of the sliding tongue 5117 and the inner side of the U-shaped guide rail 512 both have locking teeth 5120 that cooperate with each other. The rotating core 517 uses the annular tooth groove 5118 and the tooth surface 5119 to pull the sliding tongue 5117 to slide inward along the through groove 5116, so that the outer end of the sliding tongue 5117 is released from the lock with the U-shaped guide rail 512. Conversely, when the rotating core 517 uses the ring tooth groove 5118 to engage with the tooth surface 5119 to pull the sliding tongue 5117 along the through groove 5116 to mesh with the locking teeth 5120 on the inner side of the U-shaped guide rail 512, that is, the connection between the locking plate and the slot 514 is locked. By rotating the core 517 counterclockwise using the insulating operating rod 5114 and the latch 5112, the rotating core 517 uses the ring tooth groove 5118 and the tooth surface 5119 to pull the sliding tongue 5117 along the through groove 5116, so that the outer end of the sliding tongue 5117 is released from the lock of the U-shaped guide rail 512. At this time, the user can use the insulating operating rod 5114 to push and pull the end seat 513 and the locking edge 515 to move along the U-shaped guide rail 512, thereby adjusting the gap distance between the lightning rod 6 and the lightning attractor 4. The whole operation only requires half a turn of rotation and push and pull, which greatly simplifies the adjustment steps and has better operating efficiency compared to continuous turning.

[0062] Furthermore, in order to facilitate the assembly and disassembly of the lightning rod 6, the connecting mechanism 5 also includes an assembly component 52, and the end seat 513 and the locking edge 515 are connected by a locking mechanism 52.

[0063] Furthermore, the assembly component 52 includes a ring 521; the ring 521 is fixedly connected between two locking edges 515; an end seat 513 is movably connected inside the ring 521, and a stop edge 522 that cooperates with the ring 521 is fixedly connected to the top of the end seat 513; a locking groove 523 with the same diameter as the through groove 5116 is opened on the surface of the ring 521, and a sliding tongue 5117 is movably inserted into the locking groove 523. By further rotating the rotating core 517 through the insulating operating rod 5114, the sliding tongue 5117 is pulled inward to a deeper depth, and the sliding tongue 5117 slides out from the locking groove 523 on the ring 521 to unlock. When it is necessary to disassemble the lightning rod 6, the sliding adjustment function can be unlocked by inserting the insulating operating rod 5114 into the slot 518. Then, by operating the insulating operating rod 5114, the rotating core 517 can be further rotated to pull the sliding tongue 5117 inward. The sliding tongue 5117 slides out from the locking groove 523 on the ring sleeve 521 to unlock. At this time, the end seat 513 and the lightning rod 6 can be lifted off the ring sleeve 521 using the insulating operating rod 5114. This achieves quick disassembly and assembly of the lightning rod 6. The adjustment and disassembly are phased linear operations, which do not require separate operations. The overall use is convenient. Moreover, the lightning rod 6 will not move after static unlocking, which has better operational safety. This solves the technical problem in the prior art that the lightning rod 6 is prone to falling due to the direction of force when disassembling it, which poses a certain safety hazard.

[0064] In this application, the rotating core 517, the latch 5112, the sliding tongue 5117 and other related operating components are integrated into the end base 513. Two sets of functional controls can be realized with a single operating process. On the one hand, the overall structure is reduced, and on the other hand, the operating components are not exposed to the outside, which reduces the possibility of accidental activation caused by strong winds blowing plastic bags, branches and other debris.

[0065] Furthermore, the U-shaped guide rail 512 is provided with a gap corresponding scale that matches the end seat 513. By observing the gap corresponding scale, the current adjustment status of the end seat 513 can be easily understood.

[0066] Furthermore, a rotation damper is fixedly installed inside the circular groove 516; the inner ring of the rotation damper is fixedly sleeved on the surface of the rotating core 517. The rotation damper can restrict the rotating core 517 to a certain extent within the circular groove 516, and can prevent the end seat 513 and the lightning rod 6 from deflecting in the opposite direction along the rotating core 517, thus ensuring the stability of disassembly and removal.

[0067] Furthermore, the lightning rod 4 is inclined along the surface of the composite insulator skirt 2, facilitating the formation of a triangular structure between the lightning rod 4 and the composite insulator skirt 2 through a corresponding connecting structure, thereby increasing the installation stability of the lightning rod 4. Specifically, a bracket is fixedly connected between the composite insulator skirt 2 and the lightning rod 4, and this bracket forms the connecting structure. The lightning rod 4, the composite insulator skirt 2, and the bracket together form a triangular structure, which effectively increases the installation stability of the lightning rod 4.

[0068] Furthermore, the top of the composite insulator skirt 2 is fixedly connected to a power fitting 3, and is fixedly installed on the cable 1 by the power fitting 3.

[0069] This application also discloses a method for using a lightning protection device applied to the OPGW distribution line of the above embodiment two, including the following steps:

[0070] S1. Insert the insulating operating rod 5114 into the slot 518 until the latch 5112 engages in the latch groove 5115 on the surface of the insulating operating rod 5114, so that the rotating core 517 is unlocked in the circular groove 516 and can be rotated; specifically, the user inserts the insulating operating rod 5114 into the slot 518. When the insulating operating rod 5114 is inserted into the slot 518, it drives the roller 5110 to rotate accordingly, so that the latch 5112 on the roller 5110 rotates out from the groove 5113 until the latch 5112 engages in the latch groove 5115 on the surface of the insulating operating rod 5114. At this time, the rotating core 517 is unlocked in the circular groove 516 and can be rotated.

[0071] S2. Operate the insulating operating rod 5114 to rotate the rotating core 517 counterclockwise, so that the sliding tongue 5117 slides along the through groove 5116 until the outer end of the sliding tongue 5117 is released from the lock with the U-shaped guide rail 512. Then, operate the insulating operating rod 5114 to push and pull the end seat 513 and the locking edge 515 to move them along the U-shaped guide rail 512 to adjust the gap between the lightning rod 6 and the lightning attractor 4. Specifically, the user rotates the rotating core 517 counterclockwise by using the insulating operating rod 5114 in conjunction with the latch 5112. 17. Using the ring tooth groove 5118 and tooth surface 5119, the sliding tongue 5117 is pulled along the through groove 5116, so that the outer end of the sliding tongue 5117 is released from the lock with the U-shaped guide rail 512. At this time, the user can use the insulating operating rod 5114 to push and pull the end seat 513 and the locking edge 515 to move along the U-shaped guide rail 512, thereby adjusting the gap distance between the lightning rod 6 and the lightning attractor 4. The whole operation only requires half a turn of rotation and push and pull, which greatly simplifies the adjustment steps and has better operating efficiency compared to continuous turning.

[0072] S3. Operate the insulating operating rod 5114 to further rotate the rotating core 517, so that the sliding tongue 5117 retracts deeply until the sliding tongue 5117 slides out of the locking groove 523 on the ring sleeve 521 to unlock. Then operate the insulating operating rod 5114 to remove the end seat 513 and the lightning rod 6 from the ring sleeve 521. Specifically, when it is necessary to disassemble the lightning rod 6, the insulating operating rod 5114 can be inserted into the slot 518 to operate the unlocking sliding adjustment function, and then the insulating operating rod 5114 can be further rotated. Rotate the core 517 to pull the sliding tongue 5117 inward to a deeper depth. The sliding tongue 5117 slides out from the locking groove 523 on the ring sleeve 521 to unlock. At this time, the end seat 513 and the lightning rod 6 can be lifted off the ring sleeve 521 using the insulated operating rod 5114, thereby realizing the quick assembly and disassembly of the lightning rod 6. The adjustment and disassembly are staged linear operations, which do not require separate operation. The overall use is convenient. Moreover, the lightning rod 6 will not move after static unlocking, which has better operational safety.

[0073] The lightning protection device and its usage method for an OPGW power distribution line provided in this application have been described in detail above. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the ideas of the embodiments of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
