The principle of operation of the present invention will now be described as follows: each of the power distribution members is installed in a corresponding installation cavity 94 (power distribution member such as a surge protector, a circuit breaker, a fuse, a disconnecting switch, a relay, etc.), and then each member is connected through a terminal block 95 according to design requirements, and an external line is connected with the power distribution member inside the case 1, and at the same time, the control board 3 is connected with a power supply line, and then the control board 3 is started;
Initially, outdoor sunlight irradiates on the top of the annular reflective heat-insulating film 6, the annular reflective heat-insulating film 6 can reflect sunlight, and at the same time, heat conducted to the heat-insulating ceiling 2 by the sunlight irradiation is reduced, but as the sunlight irradiation time increases, the annular reflective heat-insulating film 6 can reflect sunlight and block heat conduction, but since any heat-blocking material cannot completely block heat conduction (heat is always conducted from a high temperature region to a low temperature region, the heat-blocking material is relatively poorer in heat conduction property than a common material, and cannot completely block heat conduction), the upper temperature measuring probe 82 detects the temperature rise of the side of the annular reflective heat-insulating film 6 close to the heat-insulating ceiling 2, and when the temperature reaches 55 ℃ ±3 ℃ (at this time, the portion of the annular reflective heat-insulating film 6 above the heat-insulating ceiling 2 is indicated to rise due to heat accumulation, the heat insulation performance is poor and the heat insulation requirement of the heat insulation ceiling 2 cannot be met continuously), the upper temperature probe 82 can detect that the temperature reaches the threshold range, so the upper temperature probe 82 can output an electric signal to the control board 3, at the moment, the control board 3 can control the two motor driving roller assemblies 74 to work for 1 minute at regular time, the two motor driving roller assemblies 74 can drive the roller members of the two motor driving roller assemblies to rotate in the same direction, and under the cooperation of the upper rotating roller 73, the annular reflective heat insulation film 6 is rotated clockwise or anticlockwise at a constant speed, at this time, the part of the annular reflective heat insulation film 6 above the heat insulation ceiling 2 is gradually transferred to the lower part of the heat insulation ceiling 2, while the part of the annular reflective heat insulation film 6 originally below the heat insulation ceiling 2 is moved to the upper part of the heat insulation ceiling 2, because the part of the annular reflective heat insulation film 6 is below the heat insulation ceiling 2, the temperature of the heat insulation ceiling is lower because the heat insulation ceiling is not directly irradiated by sunlight, and the annular reflective heat insulation film 6 replaces the annular reflective heat insulation film 6 which is excessively heated by sunlight irradiation, so that the top of the heat insulation ceiling 2 can be continuously subjected to reflective and heat insulation treatment, and the heat insulation ceiling 2 can maintain a better heat insulation performance;
While when the distribution box works normally, the control board 3 controls the forward fan 102 and each lower temperature measuring probe 105 to work, as the distribution work proceeds, the temperature inside each installation cavity 94 rises (because the distribution load is different, the distribution demand is different, the temperature generated when each installation cavity 94 works is not uniform, for example, the heat generated by low-load distribution is lower than the heat generated by full-load distribution when the distribution is full-load distribution or low-load distribution), each lower temperature measuring probe 105 detects the temperature inside the installation cavity 94 and converts the temperature into an electric signal to be output to the control board 3, the control board 3 controls the output power of the forward fan 102 according to the electric signal intensity output by each lower temperature measuring probe 105, for example, when the temperature inside each installation cavity 94 is higher, the electric signal intensity output by each lower temperature measuring probe 105 to the control board 3 is high, the control board 3 controls the output power of the forward fan 102 to increase, so that when the temperature inside the installation cavity 94 increases, the output power of the forward fan 102 is enough to meet the heat dissipation requirement, meanwhile, the control board 3 controls the corresponding electromagnetic suction rod 132 to supply current with corresponding magnitude according to the intensity of the electric signal output by each lower temperature measurement probe 105, for example, when the temperature inside the installation cavity 94 is high, the intensity of the electric signal output by the lower temperature measurement probe 105 at the position to the control board 3 is large, at this time, the current input by the control board 3 to the electromagnetic suction rod 132 corresponding to the lower temperature measurement probe 105 is large, and when the current supplied by the electromagnetic suction rod 132 is large, the magnetic attraction generated by the electromagnetic member inside the electromagnetic suction rod is large, so that the distance for driving the corresponding piston ring 133 to move is large, at this time, the number of the through-air holes 104 leaked out by the cylinder 103 is increased, so that more air flows can pass through the inside the installation cavity 94, to meet the heat dissipation requirement of the installation cavity 94 (because the power distribution components installed in each installation cavity 94 are different, the heat generated by each power distribution component is different, under the same power of the forward fan 102, the ventilation quantity in the installation cavity 94 with high temperature is increased, the ventilation quantity in the installation cavity 94 with low temperature is reduced, the heat dissipation airflow can be more reasonably utilized, the cooling speed in the high temperature area can be improved under the condition of meeting the cooling speed in the low temperature area, and the output power of the forward fan 102 is not required to be increased, so that the energy-saving effect is achieved to a certain extent);
When the outdoor sunlight intensity is low, the air humidity is usually higher (such as rainy days, nights, etc.), so that the air flow can pass through the hygroscopic filler 112 in the frame plate 111 before entering the inside of the box body 1 by the way that the forward fan 102 radiates heat inside the box body 1, and the hygroscopic filler 112 can adsorb water vapor in the air flow, so that the entering air flow can be dried, and the influence of external water vapor on power distribution components in the box body 1 is reduced;
When the outdoor sunlight intensity is high, the annular reflective heat insulation film 6 is heated up due to the irradiation of high-intensity sunlight, and the upper temperature measurement probe 82 detects the heating phenomenon of the annular reflective heat insulation film 6, so that when the upper temperature measurement probe 82 outputs an electric signal to the control board 3, the control board 3 controls the motor drive roller assembly 74 to work in a timing manner, and controls the reverse fan 124 to work, when the reverse fan 124 works (the control board 3 also controls the output power of the reverse fan 124 according to the electric signal intensity output by each lower temperature measurement probe 105), the reverse fan 124 can discharge air in the box 1, at this time, the external air can pass through the inside of the installation cavity 94 through the strip-shaped hole 106 (when the sunlight is strong, the air temperature is rapidly increased, the capacity of the air to contain water vapor is enhanced, so that the relative humidity is reduced, and the air flow with low humidity is not easy to influence the normal operation of power distribution components in the box 1), so that the heat of the inside of each installation cavity 94 can be dissipated, the high-heat air flow in the installation cavity 94 can enter the ventilating duct 93 through the air passing holes 104 and be discharged into the frame plate 111 through the reversing fan 124 and be discharged from the ventilating holes 113 on the side wall of the frame plate 111 through the hygroscopic filler 112, meanwhile, the excessively-warmed part of the annular reflective heat insulation film 6 due to the direct sunlight can be transferred to the lower part of the heat insulation ceiling 2, at the moment, the heat generated by the annular reflective heat insulation film 6 can be conducted to the hygroscopic filler 112 through the heat conducting frame 114, the hygroscopic filler 112 is subjected to the heat conduction effect of the annular reflective heat insulation film 6, and the steam absorbed in the inside of the hygroscopic filler 112 can be evaporated and separated through the hot air flow discharged from the inside of each installation cavity 94, so that the hygroscopic filler 112 is dried, so that when the subsequent forward fan 102 works, the hygroscopic filler 112 maintains good hygroscopic properties;
After the control board 3 receives the electrical signal output by the upper temperature measurement probe 82, the control board 3 controls the reverse fan 124 to operate regularly for 1 hour (during this period, the forward fan 102 will not operate), and after the end of the timing operation of the reverse fan 124, if the control board 3 still receives the electrical signal output by the upper temperature measurement probe 82, the control board 3 controls the reverse fan 124 to operate regularly for 1 hour again until the control board 3 does not receive the electrical signal output by the upper temperature measurement probe 82, at this time, the control board 3 will control the forward fan 102 to operate again.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
