[0022] The main switch 3 is electrically connected to the battery 14. The battery 14 is provided with four power output terminals. The first button 4, the second button 5, the third button 6 and the fourth button 7 are electrically connected to the four power output terminals respectively.

[0023] Specifically, the main switch 3 is used to control the total power of the battery 14, the first button 4 is used to control the power through the high-heat appliance plug 20, the second button 5 is used to control the power through the printer plug 22, the third button 6 is used to control the power through the audio-visual equipment plug 24, and the fourth button 7 is used to control the power through the computer plug 26.

[0024] The first button 4 is electrically connected to the first induction lamp 9 and the first overload protector 17 , the second button 5 is electrically connected to the second induction lamp 10 and the second overload protector 27 , the third button 6 is electrically connected to the third induction lamp 11 and the third overload protector 28 , and the fourth button 7 is electrically connected to the fourth induction lamp 12 and the fourth overload protector 29 .

[0025] Specifically, the lights of the first induction lamp 9, the second induction lamp 10, the third induction lamp 11, and the fourth induction lamp 12 are divided into red and green colors. When the wires are not damaged and the electricity is not overloaded, the lights of the first induction lamp 9, the second induction lamp 10, the third induction lamp 11, and the fourth induction lamp 12 will all emit green light. When the ultrasonic sensor 19 detects that the wires are damaged or the first overload protector 17 detects that the electricity is overloaded, the lights of the first induction lamp 9, the second induction lamp 10, the third induction lamp 11, and the fourth induction lamp 12 will all emit red light and turn off the corresponding power supply. When the humidity sensor 15 detects that the inside of the power connection box is damp, the lights of the first induction lamp 9, the second induction lamp 10, the third induction lamp 11, and the fourth induction lamp 12 will all emit yellow light.

[0026] The first induction lamp 9 , the second induction lamp 10 , the third induction lamp 11 , and the fourth induction lamp 12 are all connected to the ultrasonic sensor 19 by signal, and the humidity sensor 15 is connected to the main switch 3 by signal.

[0027] Specifically, the ultrasonic sensor 19 will receive ultrasonic signals generated by partial discharge when detecting a damaged wire. Partial discharge is a phenomenon that occurs when the insulating material of the wire degrades. When cracks, damage or defects appear in the insulation layer of the wire, discharges may occur at these defects under the action of a high-voltage electric field. This discharge generates ultrasonic waves, which can be captured by the ultrasonic sensor 19. When one of the ultrasonic sensors 19 detects the discharged ultrasonic wave, the corresponding first sensor light 9, second sensor light 10, third sensor light 11, and fourth sensor light 12 will emit red light, and the power supply passing through the wire will be turned off. When the wire is not damaged, the ultrasonic sensor 19 may receive environmental background noise, which comes from other ultrasonic sources in the surrounding environment, such as mechanical vibration, air flow, etc. Since the wire is well insulated and no partial discharge occurs, the ultrasonic sensor 19 will not receive the ultrasonic noise generated by the damaged wire. Specific ultrasonic signal. When one of the ultrasonic sensors 19 does not detect the discharged ultrasonic wave, the corresponding first sensor light 9, second sensor light 10, third sensor light 11, and fourth sensor light 12 will emit green light, indicating that they can be used normally. The humidity sensor 15 is used to monitor the humidity level in the power connection box to ensure that it works under safe and appropriate operating conditions. When the inside of the power connection box becomes humid, the humidity sensor 15 will detect the increase in the humidity level. When the humidity exceeds the preset safety threshold, the first sensor light 9, the second sensor light 10, the third sensor light 11, and the fourth sensor light 12 will all light up yellow, and the main switch 3 will automatically turn off the main power of the battery 14 to prevent the insulation performance of the power supply from being reduced due to humidity, increasing the risk of short circuit and leakage. When the inside of the power connection box is dry and the humidity is appropriate, the humidity sensor 15 will display normal humidity readings. Usually, within a safe range, the power connection box can be used normally.

[0028] The charging plug 13 is electrically connected to the battery 14 , the first overload protector 17 is electrically connected to the high-heat appliance plug 20 , the second overload protector 27 is electrically connected to the printer plug 22 , the third overload protector 28 is electrically connected to the audio-visual device plug 24 , and the fourth overload protector 29 is electrically connected to the computer plug 26 .

[0029] The first card block 18 , the second card block 21 , the third card block 23 , and the fourth card block 25 are all provided with wire through holes, and the wire through holes are used for passing wires. The detection end of the ultrasonic sensor 19 is aligned with the inside of the wire through holes.

[0030] A charging plug 13 is slidably connected inside the box body 1 , and a handle 8 is hinged on the front side of the box body 1 .

[0032] Specifically, the battery 14 can store electricity. When the electricity is insufficient, the battery 14 is stored by inserting the charging plug 13 into the socket. The rubber cover 30 is used to prevent dust or water from flowing into the high-heat electrical appliance plug 20, the printer plug 22, the video equipment plug, the computer plug 26, and the charging plug 13.

[0033] The following steps are involved:

[0034] S1: Turn on the main power supply of the battery 14 through the main switch 3 and take out the adapted power connector;

[0035] S2: When a person pulls out or retracts the wire, the ultrasonic sensor 19 detects damage on the surface of the wire, and the first sensor light 9, the second sensor light 10, the third sensor light 11, and the fourth sensor light 12 emit lights of different colors to remind the person according to the detection results;

[0036] Specifically, when a person needs to use a high-calorie appliance, the first button 4 is pressed, the first induction lamp 9 lights up green, the high-calorie appliance plug 20 is powered on, the rubber cover 30 of the high-calorie appliance plug 20 is opened, and the high-calorie appliance plug 20 is pulled out. During the pulling-out process, the ultrasonic sensor 19 continuously detects damage to the surface of the wire. When the surface of the wire is damaged, the ultrasonic sensor 19 detects the discharged ultrasonic wave, the first induction lamp 9 lights up red, and the first button 4 turns off the power of the high-calorie appliance plug 20 to remind the person to replace the line. When the surface of the wire is not damaged, the ultrasonic sensor 19 detects other noise ultrasonic waves, and the first induction lamp 9 lights up red. The response light 9 continuously lights up green to remind personnel that the line is intact and can be used. By bringing together various types of power connectors, when one of the devices needs to be charged, the appropriate power connector is pulled out to achieve the effect of connecting devices of different models. When the wires are pulled out or retracted, the ultrasonic sensor 19 automatically detects damage to the surface of the wires. The first induction light 9, the second induction light 10, the third induction light 11, and the fourth induction light 12 emit lights of different colors according to the detection results, thereby reminding personnel whether the wires can be used normally, effectively preventing the phenomenon of wire damage and leakage during use, and achieving a high safety effect.

[0037] S3: When the power connection box is working, the humidity sensor 15 detects the humidity value inside the power connection box, and determines whether the power connection box is wet according to the humidity value, thereby shutting down the total power supply of the battery 14;

[0038] S4: The first overload protector 17, the second overload protector 27, the third overload protector 28, and the fourth overload protector 29 respectively detect the electrical load of the corresponding circuits, and automatically shut down the power supply of the corresponding circuits when the electricity is overloaded.
