[0040] like Figure 2 As shown, a door 31 is rotatably mounted on one side of the box body 1 .

[0041] A method for using a power distribution box with a rainproof function, the method comprising:

[0042] S1. Before use, first bury the device at the location where it needs to be installed. When burying it, it is necessary to pay attention to burying half of the water tank 25 underground, then open the box door 31 and install the power supply accessories and electronic components that need to be installed on the installation plate 2 to complete the installation;

[0043] S2. When it rains during use, the inclined side of the waterproof top 3 guides the rainwater to the surroundings to avoid directly adhering to the box body 1. Meanwhile, the excess rainwater falls on the groove on the upper side of the waterproof top 3 and electrically connects the positive trigger 19 and the negative trigger 20, thereby triggering the sealing component. The sealing component seals the air inlet and the air outlet of the box body 1 at the same time, so that the interior of the box body 1 is completely sealed to prevent rainwater from entering the interior of the box body 1 through the air inlet and the air outlet. Meanwhile, the rainwater in the groove is collected into the water tank 25 through the water collecting pipe 24 to replenish the water in the water tank 25.

[0044] S3. When the weather is hot, the temperature sensor 32 will be used for monitoring. When the temperature inside the box 1 is high, the heat dissipation motor 30 can be started to dissipate the heat inside the box 1. At the same time, the water pump 27 can also be started. The water pump 27 transports the water in the water tank 25 through the pumping pipe 26 and the delivery pipe 28 to the nozzle 29, and sprays it out from the nozzle 29, so that water mist is formed above the device to cool down the area around the box 1.

[0045] Working principle of the present invention:

[0046] During use, when encountering thunderstorm weather, rainwater will be diverted along the waterproof top 3 to prevent the surface of the box body 1 from getting wet. At the same time, the connecting groove 22 in the waterproof top 3 will enter the rain, and the rainwater is conductive, which will make the positive trigger 19 and the negative trigger 20 form a passage. At this time, the driving motor 21 will be started, and the driving motor 21 will drive the threaded rod 10 to rotate, the threaded rod 10 will drive the driving block 17 to move, the driving block 17 will drive the moving plate 6 to move, the moving plate 6 will drive the spring 7 to move, the spring 7 will drive the sealing plate 8 to move, the sealing plate 8 will drive the sealing strip 9 to move, so that the sealing strip 9 moves to the gap of the dustproof net 4, and the gap of the dustproof net 4 is blocked and sealed. At the same time, the threaded rod 10 drives the primary bevel gear 11 to rotate. The primary bevel gear 11 drives the secondary bevel gear 18 to rotate, the secondary bevel gear 18 drives the transmission rod 12 to rotate, the transmission rod 12 drives the rotating rod 13 to rotate, the rotating rod 13 drives the movable plate 16 to rotate in the opposite direction through the driving block 17, so that the movable plate 16 and the ventilation plate 15 are misaligned, and the ventilation plate 15 is blocked and sealed, so that a sealed environment is formed inside the box body 1 to prevent rainwater from entering the inside of the box body 1 and causing damage to electronic components. When the rain stops, the rainwater in the connecting groove 22 is evaporated due to evaporation, so that the positive trigger 19 and the negative trigger 20 are disconnected, and the driving motor 21 will rotate in the opposite direction at this time, so that the sealing strip 9 and the movable plate 16 are reset, and the ventilation inside the box body 1 is restored;

[0047] When the box body 1 is protected from rain, excess rainwater will be transported to the water tank 25 through the water collecting pipe 24 to replenish the water in the water tank 25. When the weather is hot, it will be monitored by the temperature sensor 32. When the temperature inside the box body 1 is high, the heat dissipation motor 30 can be started. The heat dissipation motor 30 sucks air through the air inlet and discharges it through the air outlet to discharge the heat inside the box body 1. At the same time, the water pump 27 is started. The pump transports the water in the water tank 25 through the pumping pipe 26 and the delivery pipe 28 to the nozzle 29, and sprays it out from the nozzle 29, so that water mist is formed above the device, which cools down the area around the box body 1, thereby achieving the effect of cooling down the inside and outside of the box body 1.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
