[0041] Working principle: In this embodiment, the present invention also proposes a method for using the intelligent power distribution terminal, comprising the following steps:

[0042] Step 1: First, install the high and low voltage protection module 14, the fault detection module 15, the power distribution module 16 and the wireless communication module on the operation panel 6, and install the support column 17 and the positioning rod 18 on the operation panel 6, and at the same time, electrically connect the electronic valve 25 to the operation panel 6, then sleeve the heat dissipation cold source box 21 on the support column 17, and at the same time, pour the coolant into the heat dissipation cold source box 21, and make the anti-rotation grooves on the sides of the heat dissipation cold source box 21 clamp a positioning rod 18, so as to prevent the heat dissipation cold source box 21 from horizontal deflection after installation;

[0043] The second step is to install the cross plate 19 on the top of the four positioning rods 18, and fix the cross plate 19 on the top of the positioning rod 18 through the external threaded connecting tube 27, and then insert the guide rod 29 from the external threaded connecting tube 27 into the guide groove of the positioning rod 18, and install the lower nut 30, pressure spring 32, sleeve 31 and L-shaped pressing plate 33 on the guide rod 29 from the bottom end of the guide rod 29 one by one, and then screw the anti-dropping block on the bottom end of the guide rod 29 to prevent the sleeve 31 with the L-shaped pressing plate 33 from falling off the guide rod 29. At this time, the cooperation of the pressure spring 32 and the L-shaped pressing plate 33 can play the role of upper compression and limiting on the installed heat dissipation cold source box 21, so that the bottom surface of the heat dissipation cold source box 21 can be fitted to the power distribution unit, thereby improving the heat dissipation and cooling effect of the power distribution unit when in use; then push the assembled operation panel 6 with the positioning protrusion 13, the power distribution unit and the cooling mechanism into the protective cover 2;

[0044] Step three, when the positioning protrusion 13 on the operating panel 6 enters the annular groove 10 from the introduction groove 11, during this process, the operating panel 6 will squeeze the thrust ring 7 to rise, and the rise of the thrust ring 7 will facilitate the push rod 8 to compress the thrust spring 9, and when the operating panel 6 is installed into the protective cover 2, the abutment plate 20 will be abutted by the top surface of the protective cover 2, pushing the movable rod 22 toward the inside of the pressure chamber, and the return spring 23 can be compressed by the recovered movable rod 22. After the positioning protrusion 13 enters the annular groove 10 from the introduction groove 11, the positioning protrusion 13 is driven to rotate by horizontally rotating the operation panel 6. When the positioning protrusion 13 rotates horizontally in the annular groove 10, the operation panel 6 is pushed down by the thrust spring 9 and the return spring 23. Then, when the positioning protrusion 13 encounters the positioning groove 12, it can be automatically inserted into the positioning groove 12 under the action of the double thrust, and the magnetic attraction block 26 in the positioning groove 12 can magnetically fix the positioning protrusion 13 by plug-in type;

[0046] Step five, when in use, the connected external power distribution switch can be controlled by the power distribution module 16, and the high and low voltage protection module 14 arranged on the top of the operation panel 6 is convenient for realizing the protection of the power distribution module 16 during electrical connection, and the fault detection module 15 can perform real-time monitoring operation of the current grounding element of the device; after the power distribution module 16 is electrically connected to the wireless communication module, the power distribution module 16 is used to control the connected external power distribution switch and collect power measurement data; and the wireless communication module will send the power measurement data to the external central console through the 5G module, thereby achieving the purpose of intelligent power distribution monitoring, facilitating the realization of centralized line measurement, protection, control, signal monitoring and communication, and can also use the fire extinguishing dry powder 24 inside the support column 17 to timely extinguish the fire inside the protective cover 2, so as to avoid the situation where the surrounding electronic components are burned synchronously when a single electronic component catches fire, thereby improving the protection effect of the internal electronic components, and thus improving the fire prevention effect inside the equipment.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
