[0021] As described above, the primary and secondary fusion ring network box with strong comprehensive protection performance of the present invention has the following beneficial effects:

[0022] 1. The protective shell is used to protect the ring network box. The ring network box generates heat during operation, and the heat is discharged through the heat dissipation windows for dissipation. The humidity sensor is used to detect the humidity of the air to determine whether it is raining. In case of rain, the shutter mechanism is used to close the heat dissipation windows to prevent rainwater from entering the protective shell and damaging the ring network box. On rainy days, the heat dissipation windows are closed and cannot directly dissipate the heat generated by the ring network box in the protective shell. Indirect heat dissipation is achieved through water cooling. The water storage tank is used to collect rainwater, which enters the water inlet pipe through the cooling water pipe and is discharged through the drain pipe. Since the cooling water pipe is arranged on the ring network box, the flow of water in the cooling water pipe can continuously absorb the heat generated by the ring network box and dissipate the heat from the ring network box. It has a simple structure and has good heat dissipation performance even on rainy days.

[0023] 2. The energy dissipation mechanism can effectively consume the energy generated by the impact of cars and other objects on the primary and secondary fusion ring network box and the energy generated by the vibration of the primary and secondary fusion ring network box by earthquakes, thereby improving the impact resistance and seismic resistance of the primary and secondary fusion ring network box; a number of energy dissipation columns are arranged between the main rod and the installation cylinder, which effectively improves the energy dissipation capacity of the energy dissipation support; and the energy dissipation support can be self-reset through the rebound component, and then the main rod can self-reset after the energy dissipation column produces plastic yield, which can achieve the effect of continuous energy dissipation.

[0055] Brief description of the process:

[0056] Heat dissipation control: On sunny days, the humidity sensor detects that the air humidity is low, the shutter mechanism 4 keeps the heat dissipation window 3 open, and the heat generated by the ring network box 2 is dissipated through natural convection;

[0057] On rainy days, the humidity sensor detects an increase in humidity and controls the motor 441 to drive the blades 42 to close the heat dissipation window 3 to prevent rainwater from entering; at the same time, the rainwater is collected by the water tank 51, flows through the cooling water pipe 53 through the surface of the ring network box 2 for water cooling and heat dissipation, and is finally discharged from the outlet pipe 55.

[0058] Impact and vibration resistance: When the protective shell 1 is subjected to external impact or vibration, the main rod 62 is compressed to push the energy dissipation column 63 to deform to absorb energy, and at the same time the elastic member 642 is compressed to store energy; after the impact ends, the elastic member 642 pushes the main rod 62 to reset, realizing the self-recovery function.

[0059] To sum up, the present invention realizes automatic closing of the heat dissipation window 3 on rainy days through the cooperation of the shutter mechanism 4 and the humidity sensor to prevent rainwater from intruding, and at the same time uses rainwater for water cooling to ensure that the ring network box 2 can still dissipate heat efficiently in harsh environments; the energy dissipation mechanism 6 effectively absorbs impact energy and automatically resets through the coordinated action of the energy dissipation column 63 and the elastic member 642, significantly improving the impact resistance and seismic resistance of the ring network box 2.
