[0003] Outdoor meter boxes are enclosures installed outdoors to centrally house electricity metering instruments (such as meters) and related power distribution equipment. They are mainly suitable for outdoor areas such as residential buildings, commercial buildings, and industrial sites. However, when using existing outdoor meter boxes, external dust can easily enter the box and adhere to the equipment surface, affecting heat dissipation and normal operation. Furthermore, when there is a large temperature difference between day and night, water droplets can easily form inside the box, causing excessive humidity and potentially leading to safety hazards such as short circuits and electrical leakage. At the same time, long-term exposure to the outdoors can cause problems such as aging, deformation, and corrosion, resulting in a decrease in the box's sealing performance and making it difficult to provide a reliable protective environment for the internal equipment. Summary of the Invention

[0004] The main purpose of this utility model is to provide a corrosion-resistant and weather-resistant outdoor meter box, which aims to solve the problems of existing outdoor meter boxes where external dust can easily enter the box and adhere to the equipment surface, affecting heat dissipation and normal operation. Furthermore, when there is a large temperature difference between day and night, water droplets can easily form inside the box, causing excessive humidity and potentially leading to short circuits, leakage, and other safety hazards. At the same time, the box body is prone to aging, deformation, and corrosion when exposed to the outdoors for a long time, resulting in a decrease in the box's sealing performance and making it difficult to provide a reliable protective environment for the internal equipment.

[0005] To achieve the above objectives, this utility model proposes a corrosion-resistant and weather-resistant outdoor meter box, comprising a meter box structure, an air inlet louver assembly bolted to the left side of the meter box structure, an air outlet louver assembly bolted to the right side of the meter box structure, a drying box provided on the inner wall of the meter box structure, a heating assembly bolted to the inner wall of the meter box structure, a fan assembly provided on the inner wall of the meter box structure, a dust filter rack snapped onto the inner wall of the meter box structure, a base layer, a reinforcing layer provided on the surface of the base layer, a weather-resistant layer provided on the surface of the reinforcing layer, and an anti-corrosion layer provided on the surface of the weather-resistant layer.

[0006] Preferably, the reinforcing layer is made of zinc-aluminum alloy, the weather-resistant layer is made of polyvinylidene fluoride, and the anti-corrosion layer is made of nano-silica.

[0007] Preferably, a rack is bolted to the inner wall of the meter box structure, and the drying box is placed on the inner wall of the rack.

[0008] Preferably, the inner wall of the placement rack is provided with a placement groove for use with the drying box, and the inner wall of the drying box is filled with desiccant.

[0009] Preferably, connecting blocks are bolted to both the front and rear sides of the fan assembly, and insert blocks are bolted to the bottom of the connecting blocks.

[0010] Preferably, the inner wall of the meter box structure is bolted with a fixing frame, and the surface of the plug is inserted into the inner wall of the fixing frame.

[0011] Preferably, the inner wall of the meter box structure is bolted with a telescopic assembly, and a pressure block is bolted to the bottom of the telescopic assembly, with the bottom of the pressure block contacting the top of the dust filter rack.

[0012] Preferably, a limiting block is bolted to the inner wall of the meter box structure, a limiting plate is bolted to the bottom of the dust filter rack, and the surface of the limiting plate is inserted into the inner wall of the limiting block.

[0013] In this utility model's technical solution, by setting up an electric meter box structure, an air inlet louver assembly, an air outlet louver assembly, a drying box, a heating assembly, a fan assembly, and a dust filter rack, the outdoor electric meter box structure forms an air convection channel through the air inlet and outlet louver assemblies. Combined with the internal fan assembly, this effectively promotes air circulation within the electric meter box structure, reducing heat accumulation caused by equipment operation. Simultaneously, the dust filter rack intercepts dust in the air, preventing it from entering the electric meter box structure and affecting equipment operation. The drying box and heating assembly regulate the humidity within the electric meter box structure, preventing short circuits or corrosion caused by condensation, effectively ensuring the safe and stable operation of the internal equipment. Furthermore, the multi-layered composite structure of the base layer, reinforcing layer, weather-resistant layer, and anti-corrosion layer in the electric meter box structure provides progressive support from mechanical strength to environmental protection. The base layer provides the structural foundation, the reinforcing layer enhances the box's strength, the weather-resistant layer resists erosion from ultraviolet rays, wind, rain, and other natural environmental factors, and the anti-corrosion layer isolates corrosive substances such as acids and alkalis, improving the electric meter box structure's anti-aging and corrosion resistance in complex outdoor environments, extending its service life, and reducing maintenance costs.

[0028] This utility model provides a corrosion-resistant and weather-resistant outdoor meter box, which aims to solve the problems of existing outdoor meter boxes where external dust can easily enter the box and adhere to the equipment surface, affecting heat dissipation and normal operation. Furthermore, when there is a large temperature difference between day and night, water droplets can easily form inside the box, causing excessive humidity and potentially leading to short circuits, leakage, and other safety hazards. In addition, the box body is prone to aging, deformation, and corrosion when exposed to the outdoors for a long time, resulting in a decrease in the box's sealing performance and making it difficult to provide a reliable protective environment for the internal equipment.

[0029] like Figure 1-7 As shown in the figure, an outdoor meter box with corrosion resistance and weather resistance provided by this utility model includes a meter box structure 1. An air inlet louver assembly 2 is bolted to the left side of the meter box structure 1, and an air outlet louver assembly 3 is bolted to the right side of the meter box structure 1. A drying box 4 is provided on the inner wall of the meter box structure 1. A heating assembly 5 is bolted to the inner wall of the meter box structure 1. A fan assembly 6 is provided on the inner wall of the meter box structure 1. A dust filter rack 7 is snapped onto the inner wall of the meter box structure 1. The meter box structure 1 includes a base layer 101. A reinforcing layer 102 is provided on the surface of the base layer 101. A weather-resistant layer 103 is provided on the surface of the reinforcing layer 102. An anti-corrosion layer 104 is provided on the surface of the weather-resistant layer 103.

[0030] In this utility model's technical solution, by setting up an electric meter box structure 1, an air inlet louver assembly 2, an air outlet louver assembly 3, a drying box 4, a heating assembly 5, a fan assembly 6, and a dust filter rack 7, the outdoor electric meter box structure 1 forms an air convection channel through the air inlet louver assembly 2 and the air outlet louver assembly 3. Combined with the internal fan assembly 6, this effectively promotes air circulation within the electric meter box structure 1, reducing heat accumulation caused by equipment operation. Simultaneously, the dust filter rack 7 intercepts dust in the air, preventing it from entering the electric meter box structure 1 and affecting equipment operation. The drying box 4 and the heating assembly 5 can regulate the humidity within the electric meter box structure 1. To prevent short circuits or corrosion caused by condensation and effectively ensure the safe and stable operation of internal equipment, the multi-layered composite structure of the meter box structure 1, consisting of a base layer 101, a reinforcing layer 102, a weather-resistant layer 103, and an anti-corrosion layer 104, provides progressive support from mechanical strength to environmental protection. The base layer 101 provides the structural foundation, the reinforcing layer 102 enhances the strength of the box, the weather-resistant layer 103 resists the erosion of natural environments such as ultraviolet rays and wind and rain, and the anti-corrosion layer 104 isolates corrosive substances such as acids and alkalis. This improves the anti-aging and corrosion resistance of the meter box structure 1 in complex outdoor environments, extends its service life, and reduces maintenance costs.

[0031] Please refer to the following: Figure 7The reinforcing layer 102 is made of zinc-aluminum alloy, the weather-resistant layer 103 is made of polyvinylidene fluoride, and the anti-corrosion layer 104 is made of nano-silica. In this embodiment, the zinc-aluminum alloy of the reinforcing layer 102, with its excellent electrochemical protection characteristics and mechanical strength, can protect the base metal 101 from corrosion through the sacrificial anode principle and enhance the overall structural rigidity of the meter box structure 1. The polyvinylidene fluoride of the weather-resistant layer 103 has excellent resistance to ultraviolet rays and aging, and can withstand long-term corrosion from harsh outdoor climates. The nano-silica of the anti-corrosion layer 104 can form a dense protective film with ultra-small particle size, which is not only hard and wear-resistant, but also self-cleaning and hydrophobic. The three layers work together to improve the corrosion resistance and weather resistance of the meter box structure 1.

In this embodiment, the placement groove 9 on the inner wall of the placement rack 8 facilitates the placement of the drying box 4 on the inner wall of the placement rack 8. By placing desiccant 10 on the inner wall of the drying box 4, it can actively absorb humid air inside the meter box structure 1. In conjunction with the heating component 5, it can more efficiently reduce the humidity inside the meter box structure 1, effectively prevent condensation, and create a safe and stable operating environment for the equipment inside the meter box structure 1.

[0035] Additionally, please refer to Figure 5 A fixing bracket 13 is bolted to the inner wall of the meter box structure 1, and the surface of the plug 12 is inserted into the inner wall of the fixing bracket 13. In this embodiment, by setting the fixing bracket 13, the meter box structure 1 is fixed in place by the fixing bracket 13 during use, which facilitates the subsequent insertion of the fan assembly 6 into the inner wall of the fixing bracket 13, thereby facilitating the quick installation of the fan assembly 6.

[0036] Additionally, please refer to Figure 4 A telescopic assembly 14 is bolted to the inner wall of the meter box structure 1, and a pressure block 15 is bolted to the bottom of the telescopic assembly 14. The bottom of the pressure block 15 contacts the top of the dust filter rack 7. In this embodiment, by setting the telescopic assembly 14 and the pressure block 15, the position of the telescopic assembly 14 and the pressure block 15 is used to fix the dust filter rack 7, which facilitates the subsequent stable installation of the dust filter rack 7 and prevents the dust filter rack 7 from shaking randomly during use.

[0037] Additionally, please refer to Figure 4 A limiting block 16 is bolted to the inner wall of the meter box structure 1, and a limiting plate 17 is bolted to the bottom of the dust filter rack 7.
