[0035] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Specific implementation examples are given below.

[0037] Example 1:

[0038] Please see Figures 1 to 7 This utility model provides a power transmission and distribution equipment with lightning protection function, including: a box 1, a lightning protection component 3, a heat dissipation component 4 and a protection component 5, and a top plate 2 fixedly installed on the upper end of the box 1.

[0039] In this embodiment, the lightning protection component 3 guides the lightning that strikes the box 1 to the ground, preventing the lightning from damaging the internal structure of the box 1 and ensuring the normal use of the power transmission and distribution equipment. At the same time, the heat dissipation component 4 ensures the heat dissipation capacity of the box 1 and prevents excessive heat accumulation inside from damaging the parts. The protection component 5 prevents the heat dissipation component 4 from being damaged by impact and also prevents rainwater from entering the box 1 and causing damage to the internal parts of the box 1.

[0040] Example 2:

[0041] Based on Embodiment 1, a lightning protection component 3 is further disclosed. The lightning protection component 3 is installed on the upper end of the top plate 2 to prevent the power transmission and distribution equipment from being damaged by lightning strikes.

[0042] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the lightning protection assembly 3 includes: an installation block 301 fixedly installed on the upper end of the top plate 2; a stabilizing block 302 overlapping the upper end of the installation block 301; a first conductive block 303 fixedly installed inside the stabilizing block 302; a connecting block 304 fixedly installed at the lower end of the stabilizing block 302; a slot 305 opening at the lower end of the connecting block 304; a locking block 306 slidably connected inside the installation block 301; a first spring 307 provided between the locking block 306 and the installation block 301; an insulating sleeve 308 slidably connected to the outside of the installation block 301; a second conductive block 309 fixedly installed in the middle of the installation block 301; a ground wire 310 electrically connected to the rear end of the second conductive block 309; a buckle 311 fixedly installed at the rear end of the housing 1; and a lightning rod 312 fixedly installed on the upper end of the first conductive block 303.

[0043] In this embodiment, when lightning strikes the housing 1, the lightning is attracted by the lightning rod 312 and then transmitted to the first conductive block 303. The first conductive block 303 and the second conductive block 309 are in contact, and the current is then transmitted to the ground wire 310 connected to the second conductive block 309. The ground wire 310 is deeply buried in the ground, conducting the current underground to prevent damage to the housing 1 and protect its safety. Simultaneously, when the lightning rod 312 needs replacement, the insulating sleeve 308 is slid down, disengaging it from the connection between the mounting block 301 and the stabilizing block 302. Then, the stabilizing block 302 is slid. The upper end of the locking block 306 has a semi-circular design. When a certain amount of force is applied to slide the stabilizing block 302, the stabilizing block 302 drives the connecting block 304 to slide, thereby squeezing the locking block 306 and disengaging it from the slot 305, releasing the connection between the connecting block 304 and the locking block 306. Locking is then performed, followed by sliding the stabilizing block 302, which causes the first conductive block 303 to disengage from the second conductive block 309, thus enabling the stabilizing block 302 to be disassembled. This facilitates the replacement of the lightning rod 312 and ensures the normal operation of the lightning protection function. When installing a new lightning rod 312, the mating block 304 on the stabilizing block 302 is aligned with the mounting block 301 and inserted. Once the stabilizing block 302 is inserted, the first spring 307 resets, causing the locking block 306 to slide into the slot 305, thereby locking the mating block 304 and the stabilizing block 302. Subsequently, the insulating sleeve 308 is slid to cover the connection between the mounting block 301 and the stabilizing block 302, ensuring the stability of the lightning rod 312 after installation and improving its safety during use. At the same time, both the first spring 307 and the locking block 306 are insulated, ensuring the safety of the lightning protection assembly 3.

[0044] Example 3:

[0045] Based on Embodiment 1, a heat dissipation component 4 is further disclosed. The heat dissipation component 4 is installed on the left and right sides inside the housing 1 to improve the heat dissipation capacity of the housing 1.

[0046] like Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, the heat dissipation assembly 4 includes: heat dissipation grooves 401 opened on the left and right sides inside the housing 1; a connecting frame 402 slidably connected inside the heat dissipation grooves 401; a locking block 403 slidably connected inside the housing 1 at the front and rear ends of the connecting frame 402; a second spring 404 provided between the locking block 403 and the housing 1; a toggle block 405 fixedly installed on the side of the locking block 403 away from the central axis; locking grooves 406 opened on the left and right sides of the connecting frame 402; and a filter plate 407 fixedly installed inside the connecting frame 402.

[0047] In this embodiment, when the housing 1 is in use, outside air enters the housing 1 through the heat dissipation groove 401, ensuring air circulation inside the housing 1 and improving the heat dissipation capacity of the housing 1. At the same time, the filter plate 407 on the connecting frame 402 filters the air to prevent dust and impurities from entering the housing 1 from the heat dissipation groove 401 and causing corrosion to the internal structure of the housing 1. When it is necessary to replace or clean the filter plate 407, pull the lever 405 to drive the locking block 403 to slide, so that the locking block 403 is disengaged from the locking groove 406 and compresses the second spring 404. Then, pull the connecting frame 402 to disengage the connecting frame 402 from the heat dissipation groove 401, which facilitates the disassembly and installation of the filter plate 407, facilitates the replacement and cleaning of the filter plate 407, and prevents the filter plate 407 from becoming clogged and affecting the heat dissipation capacity of the heat dissipation groove 401.

[0048] Example 4:

[0049] Based on Embodiment 1, a protective component 5 is further disclosed. The protective component 5 is installed on one side of the heat dissipation component 4 and is used to provide protection for the heat dissipation component 4.

[0050] like Figure 1 , Figure 3 and Figure 4 As shown, the protective component 5 includes: a protective frame 501 that overlaps the connecting frame 402 on the side away from the central axis, a baffle 502 that is fixedly installed inside the protective frame 501, threaded posts 503 that are fixedly installed at the upper and lower ends of the connecting frame 402 on the side away from the central axis, a locking knob 504 that is threadedly connected to the outside of the threaded post 503, and a rubber pad 505 that is adhered to the side of the locking knob 504 near the central axis.

[0051] In this embodiment, several baffles 502 are installed on the protective frame 501, and the baffles 502 are designed to be inclined downwards to intercept rainwater and allow it to slide down, preventing rainwater from entering the housing 1 from the heat dissipation groove 401 and damaging the internal parts. At the same time, it also prevents the filter plate 407 from being damaged by external impacts. When the protective frame 501 needs to be replaced, turn the locking knob 504 to unscrew the locking knob 504 from the threaded post 503, then pull the protective frame 501 to disengage it from the connecting frame 402. Then, attach the new protective frame 501 to the connecting frame 402, and let the threaded post 503 observe the protective frame 501. Then, screw the locking knob 504 on. The rubber pad 505 makes the locking knob 504 make flexible contact with the protective frame 501, preventing the locking knob 504 from causing friction damage to the protective frame 501 when tightened, and facilitating the disassembly and replacement of the protective frame 501.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
