Abstract
Description
Technical Field
[0001] This utility model relates to the field of lightning protection technology, and in particular to a lightning protection device for power distribution networks. Background Technology
[0002] A power distribution network refers to a power grid that receives electrical energy from the transmission network or regional power plants and distributes it locally or in stages according to voltage to various users through distribution facilities. It consists of overhead lines, cables, poles, distribution transformers, disconnect switches, reactive power compensators, and some auxiliary facilities. It plays an important role in distributing electrical energy in the power grid. For the convenience of long-distance power transmission and for safety considerations, power is generally transmitted through poles and overhead lines. However, because poles are generally built relatively high, they are susceptible to lightning strikes. Lightning strikes can easily damage poles and paralyze local power grids. By installing lightning rods at the top of the poles, lightning can be guided to discharge to the lightning rods, and then the lightning current can be introduced into the ground through grounding wires and grounding devices, thus protecting the poles from lightning strikes.
[0003] Because lightning rods may suffer from ablation, breakage, or decreased conductivity after being subjected to lightning strikes for a long time, and if a damaged lightning rod is not replaced in time, its lightning attraction ability will be significantly reduced, or it may even lose its lightning protection function. Therefore, lightning rods need to be replaced regularly. However, since the main body of a lightning rod is usually installed by bolts, the threads of the main body of the lightning rod may strip due to frequent disassembly and assembly. Stripped threads will cause the bolts to be removed, and the lightning rod cannot be fixed. Based on the above problems, this application proposes a lightning protection device for power distribution networks. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a lightning protection device for power distribution networks to solve the aforementioned problems.

[0012] Preferably, the push column has a rectangular structure, and the longitudinal cross-sectional area of the push column is the same as the longitudinal cross-sectional area of the locking groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This lightning protection device for power distribution networks releases the fixing effect of the disassembly and assembly components on the T-shaped mounting block, allowing the lightning rod body to move the T-shaped mounting block out of the mounting groove. The T-shaped mounting block is then inserted into the mounting groove using the replacement lightning rod body, and the position of the T-shaped mounting block is fixed by the disassembly and assembly components.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: Refer to Figure 1-5A lightning protection device for power distribution networks includes a mounting frame 1. A lateral adjustment assembly is installed inside the mounting frame 1. Mounting plates 2 are installed on the left and right sides of the mounting frame 1 via the lateral adjustment assembly. A mounting groove 3 is provided through the top of the mounting plate 2. A T-shaped mounting block 4 is overlapped inside the mounting groove 3. A lightning rod body 5 is fixedly installed on the top of the T-shaped mounting block 4. A pushing assembly includes a pushing plate 13 slidably disposed inside a mounting housing 6. A pushing post 14 is fixedly installed on the side of the pushing plate 13 near the locking post 12. The pushing post 14 has a rectangular structure, and its longitudinal cross-sectional area is the same as that of the locking groove 9. The locking pin 12 is overlapped with the push plate 13. A moving rod 15 is fixedly installed on the side of the push plate 13 away from the push pin 14. The moving rod 15 is slidably installed inside the mounting housing 6. A pressing round plate 16 is fixedly installed at the end of the moving rod 15. The pressing round plate 16 drives the push plate 13 to move through the moving rod 15, so that the push pin 14 pushes the locking pin 12 out of the locking groove 9. This causes the locking pin 12 to push the moving plate 11 to push the spring 10 to compress, so that the lightning rod body 5 that needs to be replaced can be removed. This makes the disassembly of the lightning rod body 5 more convenient and the replacement speed of the lightning rod body 5 faster. The bottom of the mounting plate 2 is provided with a disassembly and assembly component, and the front of the mounting frame 1 is provided with an installation component. The assembly includes a mounting housing 6 fixedly installed at the bottom of the mounting plate 2. A limiting plate 7 is fixedly installed inside the mounting housing 6. A locking groove 9 is provided through the surface of the limiting plate 7. A movable frame 8 is overlapped inside the limiting plate 7 and fixedly installed at the bottom of the T-shaped mounting block 4. A movable plate 11 is slidably installed inside the movable frame 8. The movable plate 11 has a rectangular structure and is slidably connected to the T-shaped mounting block 4. A locking post 12 has a trapezoidal structure and is made of metal. A spring 10 connects the facing surfaces of the movable plates 11. A locking post 12 is fixedly installed on the side of the movable plate 11 away from the spring 10, and the locking post 12 is slidably connected to the locking groove 9. The connection setup includes a pushing component inside the housing 6. The pushing column 14 pushes the locking column 12 out of the locking groove 9. The lightning rod body 5 moves the T-shaped mounting block 4 upward, allowing the lightning rod body 5 to be removed. The replaced lightning rod body 5 pushes the T-shaped mounting block 4 into the mounting groove 3, causing the mounting plate 2 to push the locking column 12 to move via the inclined surface of the locking column 12. When the locking column 12 is horizontally aligned with the locking groove 9, the spring 10 pushes the locking column 12 into the locking groove 9 via the moving plate 11. This allows the moving frame 8 to fix the position of the lightning rod body 5 via the T-shaped mounting block 4, enabling the lightning rod body 5 to be quickly replaced.
[0022] Specifically, the lateral adjustment assembly includes a worm gear 17 rotatably disposed inside the mounting frame 1. A knob 18 is fixedly disposed at the rear end of the worm gear 17. A worm wheel 19 is meshed on the surface of the worm gear 17. A screw 20 is fixedly disposed inside the worm wheel 19. The screw 20 is rotatably disposed inside the mounting frame 1. A moving block 21 is threaded on the surface of the screw 20. The moving block 21 is slidably connected to the mounting frame 1. An adjustment plate 22 is fixedly disposed on one side of the moving block 21. The mounting plate 2 is fixedly disposed on the side of the adjustment plate 22 extending outside the mounting frame 1. When it is necessary to adjust the position of the lightning rod body 5, the knob 18 drives the worm gear 17 to rotate, causing the worm gear 19 to rotate. The worm wheel 19 then drives the screw 20 to rotate inside the mounting frame 1. The screw 20 drives the moving block 21, which in turn moves the mounting plate 2. The mounting plate 2 then moves the lightning rod body 5 via the T-shaped mounting block 4, thereby adjusting the installation position of the lightning rod body 5.
[0023] Specifically, the installation components include an arc-shaped plate 23 fixedly installed on the front side of the installation frame 1, an arc-shaped plate 24 overlapping the front side of the arc-shaped plate 23, and a fixing stud 25 overlapping inside the arc-shaped plate 24. The fixing stud 25 is fixedly installed on the front side of the arc-shaped plate 23, and a washer nut 26 is threaded on the surface of the fixing stud 25. The arc-shaped plate 23 is placed on the installation rod through the installation frame 1, and the arc-shaped plate 24 is placed on the front side of the arc-shaped plate 23, so that the fixing stud 25 is inserted into the interior of the arc-shaped plate 24 and passes through the interior of the arc-shaped plate 24. The washer nut 26 is tightened on the surface of the fixing stud 25, so that the arc-shaped plate 23 and the arc-shaped plate 24 are clamped on the installation rod, thereby installing the lightning rod body 5 in the designated position.
[0024] In use: When the lightning rod body 5 needs to be replaced, press the circular plate 16 to push the moving rod 15 to move it. This causes the moving rod 15 to push the pushing plate 13 closer to the limiting plate 7. The pushing plate 13 then drives the pushing column 14 to insert into the locking groove 9. This pushes the locking column 14 out of the locking groove 9, causing the locking column 12 to push the moving plate 11 to compress the spring 10. This causes the lightning rod body 5 to move the T-shaped mounting block 4 upward, which in turn moves the moving frame 8 out of the mounting housing 6. The lightning rod body 5 can then be removed. The replacement lightning rod body 5 can then be pushed... The T-shaped mounting block 4 is inserted into the mounting groove 3, causing the mounting plate 2 to push the locking pin 12 to move via the inclined surface of the locking pin 12. This causes the locking pin 12 to push the moving plate 11 to compress the spring 10. When the T-shaped mounting block 4 pushes the moving frame 8 into the mounting housing 6, the locking pin 12 is horizontally aligned with the locking groove 9. The spring 10 then pushes the moving plate 11 back to its original position, causing the moving plate 11 to push the locking pin 12 into the locking groove 9, thus fixing the position of the moving frame 8. The moving frame 8 is then fixed to the position of the lightning rod body 5 via the T-shaped mounting block 4, thus completing the replacement process of the lightning rod body 5.
