[0047] The implementation principle of the ring network box with an anti-misoperation aviation plug module in the embodiment of the present application is as follows: the desiccant 54 is placed in the breathable bag 53, the cabinet door 134 is closed, the sealing ring 51 makes the cabinet door 134 and the instrument chamber 131 sealed, the first fan 55 rotates to accelerate the air flow in the receiving tank 1311, so that the gas temperature distribution is more uniform, the desiccant 54 is accelerated to absorb water vapor in the air, and condensation is reduced. The instrument chamber 131 is sealed and not easy to exchange heat with the outside world. The gas enters from the air inlet 1314 and is discharged from the air outlet 1313 through the heat dissipation channel 1312 to achieve heat dissipation for the instrument chamber 131. The filter 61 filters impurities and the waterproof breathable membrane 62 filters water vapor, so that the water vapor content in the heat dissipation channel 1312 is small and not easy to rust. When the temperature in the receiving tank 1311 is high, the memory alloy 671 deforms and elongates, the switch 673 is turned on, and the second fan 63 rotates. To dissipate heat, when the temperature in the accommodating groove 1311 drops to normal temperature, the memory alloy 671 contracts, the abutment plate 672 abuts the switch 673, causing the second fan 63 to stop rotating, and the sliding plate 66 slides to block the air outlet 1313, reducing external impurities and water vapor from entering the heat dissipation channel 1312. The moisture-absorbing cotton 64 filters impurities and water vapor. When the air outlet 1313 is connected, the second fan 63 rotates to dry the moisture-absorbing cotton 64. When the outer box 11 is damaged or in extreme weather, external water enters the fixed groove 111, and the water-absorbing block 684 absorbs water with increased gravity, pulling the second pull rope 683 to move, causing the waterproof plate 681 to block the air outlet 1313. When the second fan 63 is rotating, the air discharged by the second fan 63 pushes the waterproof plate 681 against the elastic waterproof pad 69. When the second fan 63 stops rotating, the sliding plate 66 slides, causing the waterproof plate 681 to press against the elastic waterproof pad 69.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
