Further, still be provided with control box 14 on box 1, be provided with the core control ware in the control box 14, box 1 is provided with temperature sensor 15 in inside, is provided with rain sensor 16 on roof 10, and temperature sensor 15 and rain sensor 16 all are connected with the core control ware electricity, and electronic jar 5 and fan 6 also are connected with the core control ware electricity, consumer such as temperature sensor 15, rain sensor 16, fan 6, electronic jar 5 and core control ware all can directly get the electricity in the transformer substation, or adopt solar cell panel and battery cooperation to use and supply power.

The specific working principle is as follows:

under the natural ventilation state, hot air generated in the box floats upwards, enters the airflow channel 2 from the upper fan 601, diffuses towards the left side and the right side, and is then discharged to the outside from the air outlet 8, outside air enters from the air inlet 7, and most of the air entering from the outside naturally flows through the air outlet 3 and enters the box body 1 because the air inlet 7 and the air outlet 3 are arranged right, cooler air enters from the lower part, and hot air is discharged from the upper part to form natural convection circulation for heat dissipation.

When the temperature sensor 15 detects that the internal temperature is high, the core controller starts the upper fan 601 and the lower fan 602 to operate, so that the air circulation speed is increased, and active heat dissipation is performed; the hot air is discharged to the outside more rapidly under the influence of the upper fan 601, and the outside air entering from the air inlet 7 does not naturally enter the inside of the box body 1 from the air vent 3, and flows along the lower part of the airflow channel 2 under the action of the lower fan 602, and is blown to the inside of the box body 1 by the lower fan 602.

When raining, the rain sensor 16 on the top plate 10 detects rain water and sends a signal to the core controller in the control box 14, the core controller controls the electric cylinder 5 to extend out, the blocking plate 4 is pushed upwards, so that the solid area on the blocking plate 4 blocks the air outlet 8, the air inlet 7 and the air vent 3, external rain water and moist air are prevented from entering the interior of the box body 1, meanwhile, the fan 6 continuously works to continuously circulate the air in the box body 1, the air flows in a manner shown in fig. 3, hot air is discharged from the upper fan 601 above, circularly flows in a half circle in the air flow channel 2 and then flows back to the interior of the box body 1 from the lower fan 602, when the air flows in the air flow channel, the rain water is guided by the guide grooves 12 on the top plate 10, and the rain water is guided to the outer surface of the outer wall 102 of the box body 1 through the baffle plate 11 and the drain holes 13 on the baffle plate, make microthermal rainwater constantly wash away outer wall 102, take away a large amount of heats, the lower outer wall 102 of temperature will absorb the heat of the air in airflow channel 2, it is simply just to utilize the rainwater to cool down the air in airflow channel 2, and still be provided with hollow heat radiation fins 9 on the outer wall 102, some air still can get into among the heat radiation fins 9, reach the radiating effect of change, so the air flows half a circle back temperature in airflow channel 2 and descends by a wide margin, with this realize that the air can carry out the inner loop heat dissipation in box 1 when rainy day is angry, when preventing that rainwater and humid air from getting into box 1 inside, can also keep comparatively good radiating effect.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included within the protection scope of the present invention.
