[0002] The distribution box has the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint and environmental protection. It is the control center for commanding various components in the power supply line to reasonably distribute electric energy, the control link for reliably receiving upper power supply and correctly feeding load electric energy, and the key to obtaining user satisfaction with power supply quality. Improving the operational reliability of the power distribution box is the goal of creating high-quality projects.

[0003] With the continuous advancement of my country's urbanization process, distribution boxes play a vital role in urban infrastructure.

[0027] refer to Figure 3 As shown, the safety component 4 includes a mounting bracket 41 fixed inside the box body 1, a PLC controller 43 arranged on one side of the mounting bracket 41, and a voltage monitor 42 and a power-off switch 44 electrically connected to the PLC controller 43; by setting the voltage monitor 42, it is convenient to monitor the voltage fluctuation of electrical components.

[0028] Working principle: During use, when the temperature inside the box body 1 is too high, the water pump 221 in the water tank 21 starts, and the cold water is circulated and transported to the vicinity of the electrical components through the water supply pipe 222. When the cold water flows, it effectively takes away the heat generated by the electrical components and flows back to the water tank 21 through the return pipe 224, forming a continuous cycle. At the same time, the first motor 231 in the heat sink 23 drives the rotating rod 232 to rotate, driving the stirring blades 233 to stir the cooling water, thereby accelerating the heat dissipation of the cooling water. In addition, the exhaust fan 5 and the heat dissipation holes 234 work together to quickly discharge the heat of the cooling water returned to the inside of the water tank 21, thereby further improving the heat dissipation effect. When it rains, the water collecting bucket 241 can collect rainwater and filter out debris through the filter screen 242. The filtered rainwater enters the water tank 21 through the water injection pipe 243 , the water source evaporated when the circulating part 22 dissipates heat is replenished, automatic collection is realized, resources are saved, and maintenance costs are reduced. When an accidental fire occurs in the distribution box, the smoke alarm 35 quickly detects the burning smoke and transmits the alarm command to the PLC controller 43. After receiving the command, the PLC controller 43 immediately controls the second motor 321 to start, and the second motor 321 drives the gear 322 to rotate, and drives the sliding plate 324 to move in the sliding bin 31 through the meshing teeth 323. The movement of the sliding plate 324 further drives the connecting block 331 to slide in the slide groove 332, thereby opening the partition 333. At this time, the dry powder in the dry powder box 34 loses its obstruction and quickly pours down to extinguish the fire source in the distribution box, effectively preventing the spread of fire and improving the safety protection measures of the distribution box.
