A dustproof component is fixedly connected to the side of the surface of the main body 1 close to the heat sink 6. The dustproof component includes a dustproof net 4. Rainwater passes through the top plate 31 and collects in the water storage tank 32, flows into the water storage pipe 34 through the guide pipe 33, and the surface of the dustproof net 4 is flushed through the cleaning pipe 35 to clean the dust attached to the dustproof net 4 to avoid blockage. At the same time, the ventilation hole 64 is designed at 45 degrees. During the flushing process, rainwater will not penetrate into the distribution box to cause a short circuit, thereby improving the heat dissipation effect and safety of the distribution box.

[0024] like Figure 1-4 As shown, the dustproof net 4 is fixedly installed on the surface of the main body 1 close to the heat sink 6 by a pin 41, and the dustproof net 4 completely covers the ventilation hole 64. Due to the effectiveness of the dustproof net 4, external dust is blocked to avoid short circuit inside the distribution box, thereby extending the service life of the device.

[0025] like Figure 1-4 As shown, a door 2 is hinged on one side of the main body 1, and a handle 21 is fixedly connected to one side of the surface of the door 2. Holding the handle 21, the door 2 is driven to seal the distribution box to avoid accidental touch or misoperation.

[0026] like Figure 1-4 As shown, a plurality of equidistantly arranged heat dissipation slots 61 are provided on one side of the heat sink 6 away from the ventilation holes 64, and a rotor 62 is rotatably connected to the inner wall of the heat sink 6, and a fan blade 63 is fixedly connected to one end of the rotor 62. When the rotor 62 is energized, the fan blade 63 is driven to rotate, thereby dissipating heat inside the distribution box, avoiding damage caused by excessive temperature inside the distribution box, and further extending the service life of the device.

One side of the lower surface of the battery 5 is fixedly connected with a plurality of equidistantly arranged induction lights 51.

[0028] like Figure 1-4 As shown, a temperature sensor 52 is fixedly connected to one side of the lower surface of the battery 5 near the induction lamp 51, and a motor 53 is fixedly connected to one side of the lower surface of the battery 5 near the temperature sensor 52.

When the temperature exceeds a preset threshold value, the temperature sensor 52 sends an instruction to restore the power supply of the motor 53. The motor 53 drives the rotor 62 to rotate through the wire 54, and the rotor 62 drives the fan blades 63 to dissipate heat inside the distribution box. When the temperature drops below the threshold value, the temperature sensor 52 controls the motor 53 to cut off the power, so that the inside of the distribution box is always in a constant temperature state.

[0029] Working principle:

[0030] When in use, the distribution box is installed in a designated outdoor area, the handle 21 is pulled outward to open the box door 2, and the circuit inside the main body 1 is assembled. When it rains, rainwater drops on the surface of the top plate 31 and then slides around to the water storage tank 32 for storage;

[0031] When the temperature inside the distribution box is too high and needs to be cooled, the temperature sensor 52 is triggered, and the temperature sensor 52 sends a command to the motor 53. The motor 53 supplies power to the rotor 62 through the wire 54. The rotor 62 drives the fan blades 63 to rotate and blows the heat inside the main body 1 to the outside through the heat dissipation slots 61 and the ventilation holes 64. The ventilation holes 64 are designed at 45 degrees, and the dissipated heat is dissipated to the outside at 45 degrees.

[0032] The dustproof net 4 is fixedly installed on the side of the main body 1 surface close to the heat sink 6 by a pin 41, and the dustproof net 4 fully wraps the ventilation hole 64 to block the dust and prevent external dust from entering the distribution box. After a long period of use, a large amount of dust will accumulate on the surface of the dustproof net 4, causing blockage, which affects the heat dissipation effect. When the dustproof net 4 is blocked, rainwater passes through the top plate 31 and collects in the water storage tank 32, flows into the water storage pipe 34 through the guide pipe 33, and the surface of the dustproof net 4 is flushed through the cleaning pipe 35 to clean the dust attached to the dustproof net 4. The ventilation hole 64 is designed at 45 degrees. During the flushing process, rainwater will not penetrate into the distribution box to cause a short circuit. The safety of the device is guaranteed, and it is suitable for large-scale promotion.
