The inner wall of the box body 1 is fixedly connected to a temperature sensor 20 , the temperature sensor 20 is electrically connected to a PLC controller, and the PLC controller is electrically connected to a buzzer 21 . The outer surface of the casing 31 is fixedly connected to the display 22 , and the display 22 is electrically connected to the temperature sensor 20 .

Specifically, the working process or working principle of a low-voltage power distribution box with heat dissipation function in a low-voltage power distribution area is as follows: when in use, move the casing 31 to a place where it needs to be used and is stable, and then fix and install the electrical components in the box. The positioning plate 16 inside the body 1, and electrically connect the electrical components with the external power supply, so that the distribution box can be used normally. At the same time, the fan 32 and the temperature sensor 20 inside the box body 1 are also connected to the external power supply. When the components inside the body 1 are in normal use, the fan 32 will also work normally. After the components inside the box 1 work for a period of time, a certain amount of heat will be generated. At this time, the heat inside the box 1 will be sucked out by the fan 32 and passed through the box The exhaust hole 33 on the top of the body 1 discharges the heat from the inside of the casing 1, and then discharges it into the atmosphere from the exhaust hole 33 on the top of the casing 31 to dissipate heat inside the casing 1.

Because the bottom surface of housing 31 is provided with air inlet 7, and the bottom surface of casing 1 is provided with through hole 8, the outside air can enter from air inlet 7 naturally, and enters the inside of casing 1 through through hole 8, to casing 1 At the same time, when the air inside the box 1 is sucked by the fan 32, part of the hot air will be discharged from the inside of the box 1 through the position of the heat dissipation hole 5, which can improve the internal heat dissipation effect of the box 1. Through the heat dissipation hole 5 The exhausted air will rise naturally, and the air will be discharged into the atmosphere through the position of the round hole 4, so that the hot air inside the box body 1 can be discharged into the atmosphere in time, so as to quickly dissipate the heat inside the box body 1. If the box When the temperature inside the body 1 is too high, the temperature inside the box 1 is detected by the temperature sensor 20, and the temperature is displayed on the display 22. At the same time, the buzzer 21 is controlled by the PLC controller to give an alarm, so as to remind the staff to timely pair The electrical box stops working to avoid danger.

When transporting the whole, manually pull the handle 13, and drive the connecting rod 311 to move by pulling the handle 13, so that the hand can hold the handle 13, and the whole can be lifted to move to other positions that need to be used, and then the whole device can be laid flat After that, the handle 13 is released, and now the handle 13 will be contracted by the spring 12, so that the handle 13 is attached to the outer surface of the shell 31, which does not take up space and is convenient to use.

By setting the dustproof plate 18 on the top of the housing 31, it is possible to prevent external dust and impurities from entering the inside of the box body 1 through the exhaust hole 33, effectively protecting the internal components of the box body 1, and prolonging the service life of the components. The heat dissipation of the distribution box can also prevent external dust and impurities from entering the inside of the box body 1, thereby protecting the internal components of the box body 1 and avoiding damage.

It should be noted that the temperature sensor 20, the buzzer 21 and the display 22 are devices or equipment existing in the prior art, or devices or equipment that can be realized in the prior art. It is clear to the personnel, so it will not be described in detail.
