[0022] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a power distribution cabinet with a waterproof structure, comprising a power distribution cabinet body 1 and heat dissipation holes 2, heat dissipation holes 2 are opened on both sides of the power distribution cabinet body 1, and the heat dissipation holes 2 can be used to discharge the heat inside the power distribution cabinet body 1, and a waterproof mechanism 3 is provided on the power distribution cabinet body 1 to prevent rainwater from penetrating into the heat dissipation holes 2. By setting the waterproof mechanism 3, rainwater can be prevented from penetrating into the inside of the power distribution cabinet body 1 through the heat dissipation holes 2.

[0023] The above-mentioned waterproof mechanism 3 includes a rain shield 31, one side of the rain shield 31 is hinged to the inner wall of the heat dissipation hole 2, and the other side of the rain shield 31 is hinged with a connecting rod 34, the sliding rod 32 is slidably connected to the top of the distribution cabinet body 1, and the sliding rod 32 runs through the distribution cabinet body 1, the top of the sliding rod 32 is fixedly installed with a limit block 36, and the bottom of the sliding rod 32 is fixedly installed with a water collecting box 35. The water collecting boxes 35 on both sides of the distribution cabinet body 1 will collect rainwater on rainy days. When the rainwater in the water collecting box 35 gradually increases, the mass of the water collecting box 35 will gradually become heavier. At this time, under the guiding action of the sliding rod 32, the water collecting box 35 will gradually move down and compress the spring 38. One end of the connecting rod 33 is hinged at the bottom of the water collecting box 35, and the other end of the connecting rod 33 is hinged at the top of the connecting rod 34. Through the up and down movement of the water collecting box 35, the connecting rod 33 and the connecting rod 34 can drive multiple groups of rain shields 31 to rotate synchronously, thereby controlling the opening and closing of the heat dissipation hole 2 When the water level in the water collecting box 35 reaches the height of the overflow pipe 39, the water will be discharged to the bottom of the water collecting box 35 through the overflow pipe 39 to prevent rainwater from overflowing and splashing on the outer wall of the distribution cabinet body 1.

[0024] Working principle: When the distribution cabinet body 1 is set outdoors and exposed to rain, the water collecting boxes 35 on both sides of the distribution cabinet body 1 will collect rainwater. When the rainwater inside the water collecting box 35 gradually increases, the mass of the water collecting box 35 will gradually become heavier. At this time, under the guidance of the slide bar 32, the water collecting box 35 will gradually move downward and compress the spring 38. At this time, the water collecting box 35 will push the connecting rod 33 to move downward, and at the same time, the connecting rod 33 will squeeze the connecting rod 34. At this time, the connecting rod 34 will push multiple groups of rain shields 31, so that the multiple groups of rain shields 31 will rotate downward synchronously and fit on the outer wall of the distribution cabinet body 1, so that the rain shields 31 will cover the heat dissipation holes 2 to prevent rainwater from splashing into the interior of the distribution cabinet body 1 through the heat dissipation holes 2. When the water level inside the water collecting box 35 reaches the height of the overflow pipe 39, the water flow will be discharged to the bottom of the distribution cabinet body 1 through the overflow pipe 39 to prevent rainwater from overflowing and splashing on the outer wall of the distribution cabinet body 1.
