[0030] Embodiment 1: An outdoor distribution box with protection function, such as Figure 1-Figure 4 As shown, it comprises: a distribution box 1 and a breathable plate 2, wherein the front bottom of the distribution box 1 is fixedly provided with a breathable plate 2, and a grid opening with a filter is provided in the breathable plate 2; a waterproof top cover 3, fixedly provided on the top of the distribution box 1, the waterproof top cover 3 can cover the entire top of the distribution box 1, and is used to block rainwater falling into the distribution box 1; an air-drying box 4, the upper rear side of the distribution box 1 is sealed and connected to the air-drying box 4 through an opening, the distribution box 1 and the air-drying box 4 are connected as a whole, and the rear side of the air-drying box 4 is an opening; an air-drying component 5, arranged between the distribution box 1 and the air-drying box 4, the air-drying component 5 is used to blow air inside the entire distribution box 1, so that the distribution box 1 has the function of air-drying the moisture attached thereto; the air-drying component 5 comprises: a mounting block 51, which is set to two symmetrical blocks on the left and right and fixedly provided on the top side of the inner wall of the air-drying box 4; a drying fan group 52, rotatably installed between the two mounting blocks 51, The end of the rotating shaft of the drying fan group 52 passes through the outside of the air drying box 4, and the drying fan group 52 is provided with multiple groups of fans for drying; the spur gears 53 are symmetrically fixedly installed on the two ends of the rotating shaft of the drying fan group 52; the reset spring 54 is arranged between the inner wall of the air drying box 4 and the drying fan group 52, and the number of the reset springs 54 is not less than two; the baffle member 6 is arranged at the opening on the rear side of the air drying box 4, the baffle member 6 can seal and block the opening on the rear side of the air drying box 4, and the baffle member 6 is used to cooperate with the drying fan group 52, then open the opening on the rear side of the air drying box 4 and speed up the drying rate of the inside of the distribution box 1. When it rains, when part of the rainwater or water vapor penetrates into the inside of the distribution box 1 through the gap, the water vapor inside the distribution box 1 can be removed by activating the drying fan group 52 to prevent the distribution box 1 from being damp for a long time in rainy weather and affecting normal operation.

[0031] like Figure 1 , Figure 8 and Fig. 9As shown, a sealing baffle 21 is provided on the air permeable plate 2, and the sealing baffle 21 is rotatably installed on the inner bottom of the air permeable plate 2, and a torsion spring is provided on the rotating shaft of the sealing baffle 21 connected to the air permeable plate 2. Initially, the sealing baffle 21 seals and blocks the grid opening on the air permeable plate 2, and the sealing baffle 21 is tightly fitted on the air permeable plate 2 through the elastic force of the torsion spring, and the grid opening is sealed and closed. When the drying fan group 52 is used to dehumidify and dry the distribution box 1 on a sunny day, the sealing baffle 21 can be opened to increase the air flow exchange rate inside and outside the distribution box 1, thereby improving the dehumidification efficiency of the distribution box 1.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the baffle member 6 includes a bellows baffle 61, a mounting rotating plate 62 and a spur rack 63. The mounting rotating plate 62 is symmetrically rotatably installed on the left and right side walls of the outside of the air-drying box 4. The bellows baffle 61 is slidably installed at the rear opening of the air-drying box 4 through the two mounting rotating plates 62. A sliding groove frame adapted to the mounting rotating plate 62 is provided on the outer surface of the bellows baffle 61. Under the limit of the mounting rotating plate 62, the bellows baffle 61 can slide horizontally from the air-drying box 4 to realize the opening and closing of the rear opening of the air-drying box 4. A spur rack 63 is fixedly provided on the inner side of the bellows baffle 61 near the distribution box 1. The spur rack 63 is provided with two and is slidably connected to the inner wall of the air-drying box 4. By sliding on the air-drying box 4 The bellows baffle 61 is slid up and closed so that the bellows baffle 61 covers the air-drying box 4 on rainy days. The bellows baffle 61 is slid open on the air-drying box 4 to open the opening of the air-drying box 4 so as to cooperate with the drying fan group 52 for air-drying. The edges of the sealing baffle 21 and the bellows baffle 61 are provided with waterproof pads, which are used to improve the sealing and waterproof properties of the sealing baffle 21 and the bellows baffle 61 when they are closed, so that liquids such as rainwater cannot penetrate into the inside of the distribution box 1 from the grid opening of the air permeable plate 2. After the bellows baffle 61 closes the air-drying box 4, rainwater cannot enter into the distribution box 1 from the air-drying box 4, so that the distribution box 1 has good sealing properties.

[0033] When the outdoor distribution box 1 is used outdoors, when encountering rainy and humid weather, the waterproof top cover 3 will block the top of the distribution box 1, so that the falling rainwater is blocked by the waterproof top cover 3 and diverted to the periphery of the distribution box 1, and part of the diverted rainwater will slide from the waterproof top cover 3 to the air drying box 4. At this time, since the bellows baffle 61 is closed at the opening of the air drying box 4, it cannot flow into the inside of the air drying box 4. At the same time, the rainwater falling on the air permeable plate 2 will also be blocked on the outside of the distribution box 1 by the closed sealing baffle 21. When the distribution box 1 is in rainy and humid weather for a long time, part of the rainwater will inevitably cover the outside of the distribution box 1, and part of the water vapor will enter the box through the gap of the distribution box 1. At this time, by activating the drying fan group 52, the drying fan group 52 can blow and dry the water vapor that penetrates into the inside of the distribution box 1, thereby reducing the influence of water vapor on the electrical components inside the distribution box 1.

[0034] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a linkage assembly 7 is provided on the outside of the air-drying box 4, and the linkage assembly 7 includes: a U-shaped sliding frame 71, which is slidably installed on the outside of the air-drying box 4, and the U-shaped sliding frame 71 spans from the bottom side of the air-drying box 4 to the left and right sides, and the vertical ends of the U-shaped sliding frame 71 are tightly attached to and slidably installed on the left and right outer walls of the air-drying box 4; an L-shaped rack 72, which is provided with two symmetrical left and right racks and is respectively fixedly arranged at the middle of the left and right vertical ends of the U-shaped sliding frame 71, and the L-shaped racks 72 are both slidably connected to the left and right outer walls of the air-drying box 4; a double-layer gear 73, which is symmetrically rotatably installed on the left and right side walls of the air-drying box 4, and the inner gear of the double-layer gear 73 is located on the inner side of the air-drying box 4, and the outer gear of the double-layer gear 73 is located on the outer side of the air-drying box 4, wherein the inner gears are all aligned with the corresponding The straight rack 63 is meshed with the outer gears, and the outer gears are meshed with the corresponding L-shaped racks 72; the linkage racks 74 are symmetrically fixed on the top of the vertical ends of the U-shaped sliding frame 71, and the linkage racks 74 are meshed with the corresponding spur gears 53 on the same side. By pulling the bellows baffle 61 to slide horizontally, the bellows baffle 61 will drive the straight rack 63 to mesh with the double-layer gear 73, and then the double-layer gear 73 is meshed to drive the U-shaped sliding frame 71 and the L-shaped rack 72 to rise and fall as a whole. Finally, the rising and falling linkage rack 74 meshes and drives the spur gear 53 to rotate, thereby driving the drying fan group 52 to flip over in the air drying box 4, so that the drying fan group 52 adapts to the bellows baffle 61 and improves the drying rate of the distribution box 1.

[0035] like Figure 2 , Figure 6 and Figure 7As shown, a locking member 10 is provided on the outside of the air drying box 4, and the locking member 10 is used to lock the double-layer gear 73. The locking member 10 includes a U-shaped connecting rod 101 and an elastic block 102. The U-shaped connecting rod 101 is slidably installed on the outside of the top of the air drying box 4, and the elastic block 102 is symmetrically arranged on the left and right ends of the U-shaped connecting rod 101. The elastic block 102 is connected to the air drying box 4, and the elastic block 102 and the U-shaped connecting rod 101 constitute a locking member 1 0 as a whole, initially, the elastic card block 102 is respectively clamped on the outer gear of the corresponding double-layer gear 73 on the same side under the action of its internal spring, and the locked double-layer gear 73 will limit the bellows baffle 61 through the corresponding spur rack 63, so that the bellows baffle 61 is initially sealed and closed at the rear opening of the air-drying box 4, and under the locking of the locking member 10, the bellows baffle 61 cannot be opened at will, thereby improving the stability of the bellows baffle 61 in covering the air-drying box 4.

[0036] When the rain stops and the sky clears, the user can, without moving the distribution box 1, first pull the U-shaped connecting rod 101 upward by overcoming the elastic force of the elastic block 102, so that the elastic block 102 is no longer stuck on the double-layer gear 73, and then directly pull the bellows baffle 61 from the air-drying box 4 to open it. The bellows baffle 61 will slide open horizontally away from the distribution box 1 with the cooperation of the mounting rotating plate 62. At this time, the bellows baffle 61 will drive the spur rack 63 to slide synchronously, and the spur rack 63 sliding away from the distribution box 1 will mesh with the corresponding double-layer gear 73. The inner gear drives the double-layer gear 73 to rotate, and the outer gear of the rotating double-layer gear 73 will mesh with and drive the corresponding L-shaped rack 72 to slide downward. The downwardly moving L-shaped rack 72 will drive the U-shaped sliding frame 71 to slide downward together. At this time, the sliding U-shaped sliding frame 71 will drive the linkage rack 74 on its top to move downward synchronously, and finally the linkage rack 74 will mesh with the spur gear 53 to rotate. The rotating spur gear 53 will act on the rotating shaft of the drying fan group 52, thereby driving the drying fan group 52 to overcome the elastic force of the reset spring 54. The force flips downward, and when the bellows baffle 61 is completely slid open from the opening at the rear side of the air-drying box 4, the U-shaped connecting rod 101 is loosened, so that the elastic block 102 is reset and stuck in the double-layer gear 73 under the action of its internal spring. The locked double-layer gear 73 will limit the sliding of the spur rack 63 by meshing, so that the bellows baffle 61 can maintain a stable open state at the rear side of the air-drying box 4. At this time, the drying fan group 52 will also change from blowing towards the bottom side of the air-drying box 4 to blowing air directly into the distribution box 1, and then cooperate with the air flow at the opening at the rear side of the air-drying box 4 to make the drying The fan group 52 can quickly dry the moisture or residual water inside the distribution box 1. When the inside of the distribution box 1 is dried, the bellows baffle 61 is slid closed on the drying box 4. Similarly, through the meshing action of the spur rack 63, the double-layer gear 73 and the L-shaped rack 72, the U-shaped sliding frame 71 is again meshed through the linkage rack 74 to drive the spur gear 53 to reset and rotate, and the restoring force of the reset spring 54 on the drying fan group 52 is cooperated to realize the automatic reset of the drying fan group 52 to the original position, thereby conveniently drying the damp distribution box 1.

[0037] Embodiment 3: Based on embodiment 2, Figure 6 and Figure 7 As shown, a dust filter frame 8 is also included. Symmetrical sliding slots are provided on both side walls of the rear opening of the air drying box 4. The dust filter frame 8 is slidably installed at the rear opening of the air drying box 4 through the sliding slots. The dust filter frame 8 is used to block dust from entering from the rear opening of the air drying box 4, so that when the wind box baffle 61 is slid open for ventilation and drying, dust in the air cannot enter the distribution box 1.

[0038] like Figure 3 , Figure 6 , Figure 8 and Fig. 9 As shown, a pulling assembly 9 is provided inside the distribution box 1, and the pulling assembly 9 includes a rope seat 91, a winding wheel 92 and a pull rope 93. The rope seat 91 is provided with two and fixedly provided on the bottom side of the distribution box 1. The winding wheel 92 is provided with two and fixedly installed on the bottom side of the air drying box 4, and the winding wheels 92 are respectively adapted to the corresponding rope seats 91. The two ends of the pull rope 93 are respectively fixedly connected to the top of the sealing baffle 21, and the two ends of the pull rope 93 are respectively passed through the corresponding rope seats 91, and the middle part of the pull rope 93 is wound around the two winding wheels 9. 2, the middle part of the pull rope 93 passes through the bottom opening of the air-drying box 4 and extends to the outer bottom side of the air-drying box 4. A hook is provided at the bottom of the U-shaped sliding frame 71, and the hook is used to adapt to and pull the pull rope 93. When the U-shaped sliding frame 71 descends, the hook at the bottom of the U-shaped sliding frame 71 will pull the pull rope 93 downward. After the pull rope 93 passes through the sliding guide of the rope seat 91 and the winding wheel 92, it will pull the sealing baffle 21 to rotate around its rotating axis to open, thereby automatically opening the sealing baffle 21 from the air-permeable plate 2 so as to adapt to the distribution box 1 for drying.
