Classified by purpose, it can be divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. Power distribution cabinets are used to distribute power to equipment such as motors; lighting distribution cabinets are used to distribute lighting power; and metering cabinets are used to measure electrical energy. Existing distribution cabinets must be protected from lightning when in use to ensure a stable power supply. If a distribution cabinet is struck by lightning, a surge will occur, damaging electrical components and adversely affecting their daily use. Therefore, we propose a power distribution cabinet with lightning protection.

[0004] In view of the above description, the applicant believes that the following problems exist: This power distribution cabinet with lightning protection function uses a cabinet body, an extension rod, a lightning rod body, etc. to achieve lightning protection effect. This lightning rod cannot remove dust and debris attached to the surface when used for a long time, which affects the conductive effect. The lightning rod is installed on the right side of the distribution cabinet. When lightning strikes, the lightning rod may generate strong electromagnetic induction nearby during the process of leading lightning into the ground, inducing high voltage and large current in the lines and equipment of the distribution cabinet, which may cause damage to the electrical components in the distribution cabinet.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The power distribution cabinet with lightning protection function has a lightning protection component. When the distribution cabinet body is used and the lightning rod is placed in the mounting seat for installation and use, the servo motor drives the first threaded rod to drive the moving frame and the limit frame to rise and fall, so that the first cleaning brush cleans the lightning rod, which can effectively remove dust, debris, etc. on the lightning rod, ensuring that it is always in a good conductive state, improving the lightning protection effect, and under the action of the limit frame, it can further support and protect the lightning rod to ensure the stability of the lightning rod.

[0017] 2. The power distribution cabinet with lightning strike prevention function has an installed assembly. When the lightning rod is inside the mounting seat and the first threaded rod rotates, the second threaded rod is driven to rotate through the first pulley, the transmission belt and the second pulley, so that the rectangular plate moves up and down along the first threaded rod. When the rectangular plate moves, the connecting shaft and the first extrusion shaft are driven to move, and the first extrusion shaft squeezes the second extrusion shaft, so that the plug block is inserted into the mounting seat and the lightning rod, and the third spring is deformed, which can further limit and fix the lightning rod, ensure the stability of the lightning rod and facilitate installation and disassembly.

[0018] 3. The power distribution cabinet with the function of preventing lightning strikes has a lightning-inducing ground mechanism. When the distribution cabinet body is in use and the lightning rod is installed and used, the first grounding wire is connected to the mounting base to introduce lightning into the ground. The first grounding wire, the connecting plate and the second grounding wire are in a connected state, and the second grounding wire is connected to the grounding plate, which further enhances the reliability of grounding. The rod at the bottom of the grounding plate is inserted into the ground to increase the grounding area. The auger can be rotated by the knob to go deeper into the ground, thereby improving the grounding effect, effectively ensuring the safety of the power distribution cabinet during lightning strikes, and playing a role in lightning protection. In the process of connecting the first grounding wire to the mounting base, the linkage effect in work is realized, further expanding the role of lightning protection.

[0019] 4. The power distribution cabinet with lightning strike prevention function, through the provided limiting mechanism, when under the driving action of the first threaded rod, the second extrusion shaft is limited by the first extrusion shaft under the action of the first pulley, the second pulley, the transmission belt and the second threaded rod, so that the plug block is inserted into the interior of the lightning rod and its installation and fixation are completed, the electric telescopic rod in the installation frame can push the connecting sleeve to insert or pull out the limiting rod into or out of the limiting disk, thereby limiting the second threaded rod, thereby limiting the second pulley, so that the transmission belt cannot continue to drive the second pulley to work, thereby ensuring that the second threaded rod does not continue to rotate with the first threaded rod, thereby ensuring the stability of the plug block when working, and the limiting rod is connected to the electric telescopic rod by a fixing pin and a connecting sleeve. When the electric telescopic rod is damaged, it is easy to disassemble and replace. BRIEF DESCRIPTION OF THE DRAWINGS

Example 4

[0032] See Figure 1-10 On the basis of Example 1, Example 2, and Example 3, the limiting mechanism 4 is further obtained to include a mounting frame 41, the mounting frame 41 is fixedly connected to the left side of the load-bearing frame 213, an electric telescopic rod 42 is slidably connected inside the mounting frame 41, a connecting sleeve 43 is fixedly connected to the right side of the electric telescopic rod 42, a limiting rod 45 is inserted into the connecting sleeve 43, the limiting rod 45 is slidably connected to the inside of the load-bearing frame 213, a fixing pin 44 is threadedly connected to the inside of the limiting rod 45, a limiting disk 46 is inserted into the periphery of the limiting rod 45, and the limiting disk 46 is fixedly connected to the periphery of the second threaded rod 225.

The fixing pin 44 is threadedly connected to the limiting groove, so that the limiting rod 45 can be connected to the electric telescopic rod 42 through the connecting sleeve 43 under the action of the fixing pin 44, and it is also convenient for assembly.

[0034] In actual operation, when this device is used, when the power distribution cabinet body 1 is used and the lightning rod 2192 is placed in the mounting seat 2193 for installation, the first threaded rod 214 is driven by the servo motor 211. When the first threaded rod 214 rotates, the second threaded rod 225 is driven to rotate through the first pulley 221, the transmission belt 222 and the second pulley 223, so that the rectangular plate 224 moves up and down along the first threaded rod 214. When the rectangular plate 224 moves, it drives the connecting rod 225 to rotate. The shaft 227 and the first extrusion shaft 228 move, and at the same time, the first extrusion shaft 228 squeezes the second extrusion shaft 229, so that the plug 2293 is inserted into the mounting seat 2193 and the interior of the lightning rod 2192, and at the same time, the third spring 2292 is deformed, which can further limit and fix the lightning rod 2192, ensuring the stability of the lightning rod 2192 while facilitating installation and removal. When the second threaded rod 225 rotates, the plug 2293 is inserted into the interior of the lightning rod 2192; The electric telescopic rod 42 in the mounting frame 41 can push the connecting sleeve 43, so that the limiting rod 45 is inserted into or pulled out of the limiting plate 46, thereby limiting the second threaded rod 225, thereby limiting the second pulley 223, so that the transmission belt 222 cannot continue to drive the second pulley 223 to work, thereby ensuring that the second threaded rod 225 does not continue to rotate with the first threaded rod 214, ensuring the stability of the insert block 2293 when working. The limiting rod 45 is connected to the electric telescopic rod 42 through the fixing pin 44 and the connecting sleeve 43. When the electric telescopic rod 42 is damaged, it is easy to disassemble and replace; When the lightning rod 2192 is installed, the first threaded rod 214 rotates and drives the movable frame 218, the limiting frame 219 and the first cleaning brush 2191 to move, so that the first cleaning brush 2191 cleans the lightning rod 2192, which can effectively remove dust, debris, etc. on the lightning rod 2192, ensuring that it is always in a good conductive state, improving the lightning protection effect, and under the action of the limiting frame 219, it can further support and protect the lightning rod 2192, ensuring the stability of the lightning rod 2192, and at the same time The first threaded rod 214 drives the half gear 2195 to rotate through the rotating rod 2194 under the action of the first sprocket 212, the chain 215 and the second sprocket 216. The half gear 2195 engages with the rack 2196, causing the mounting frame 2197 to move back and forth, and causing the rack 2196 to slide around the outer periphery of the first slide rod 2199 to squeeze the first spring 21991. The second cleaning brush 21992 cleans the right side of the power distribution cabinet body 1 to prevent dust accumulation from affecting the air intake effect, thereby improving the heat dissipation effect of the power distribution cabinet body 1. When the first threaded rod 214 drives the movable frame 218 to move to the top, the half gear 2195 can rotate one circle. When the half gear 2195 does not engage with the rack 2196 during the rotation, the rack 2196 can return to the initial position under the elastic action of the first spring 21991, waiting for the half gear 2195 to re-engage, thereby ensuring the back and forth reciprocating work of the second cleaning brush 21992. The second cleaning brush 21992 is fixed to the inside of the mounting frame 2197 by the second spring 21994, the pull ring 21995 and the block 21996, which not only ensures the stability of the second cleaning brush 21992, but also facilitates the replacement of the second cleaning brush 21992. A servo motor 211 and a first threaded rod 214 can realize the linkage of cleaning the air inlet of the distribution cabinet and cleaning the lightning rod 2192 at the same time, which greatly improves the cleaning efficiency and can complete the two cleaning tasks in a shorter time. When the lightning rod 2192 is in use, the first grounding wire 31 is connected to the mounting base 2193 to introduce lightning into the ground. The first grounding wire 31, the connecting plate 32 and the second grounding wire 33 are in a connected state, and the second grounding wire 33 is connected to the grounding plate 36, further enhancing the reliability of the grounding. The plug rod 37 at the bottom of the grounding plate 36 is inserted into the ground to increase the grounding area. The auger 38 can be rotated by the knob 35 to further penetrate the ground, thereby improving the grounding effect, effectively ensuring the safety of the power distribution cabinet during lightning strikes, and playing a role in lightning protection. In the process of connecting the first grounding wire 31 to the mounting base 2193, a linkage effect is achieved during work, further expanding the role of lightning protection.
