The first magnet 19 and the second magnet 20 attract each other, so that the drying degree of the drying agent layer 13 is increased, and the conditions that the drying box 11 frequently and repeatedly lifts and opens and closes the heating pipe 16 are reduced.
Referring to fig. 7 and 8, the cabinet 1 is provided with a second fan 6, and the second fan 6 includes a first motor 61 and blades 62. The first motor 61 is fixedly installed at one side of the cabinet body 1 where the first air outlet 7 is formed, and the fan blades 62 are fixedly installed at the rotating shaft of the first motor 61. The fan blade 62 is located outside the cabinet 1, and the fan blade 62 faces the first air outlet 7. The first motor 61 is started, and the first motor 61 drives the fan blades 62 to rotate, so that air enters the cabinet 1 from the first air outlet 7.
The rotation shaft of the first motor 61 is provided with a reduction mechanism 21, and the reduction mechanism 21 includes a reduction gearbox 211, a first gear 212, and a second gear 213. The first gear 212 and the second gear 213 are both located inside the reduction gearbox 211, and the first gear 212 is fixedly mounted to the rotation shaft of the first motor 61. The first gear 212 and the second gear 213 are engaged with each other, and the number of teeth of the first gear 212 is smaller than the number of teeth of the second gear 213. The second gear 213 is fixedly provided with a rotary rod 22, and both sides of the first filter screen plate 8 are provided with first hairbrushes 23, and the first hairbrushes 23 are abutted against the first filter screen plate 8. The rotary rod 22 penetrates through the middle part of the first filter screen plate 8, and two first hairbrushes 23 are fixedly arranged on the rotary rod 22.
After the first motor 61 is started, the first motor 61 drives the first gear 212 to rotate, and the first gear 212 drives the second gear 213 to rotate. The second gear 213 drives the rotating rod 22 to rotate, and the rotating rod 22 drives the first hairbrush 23 to rotate, so that the first filter screen plate 8 is cleaned. By keeping the first screen 8 clean, it is reduced that the first screen 8 is blocked by debris and affects the heat dissipation of the cabinet 1. The number of teeth of the first gear 212 is smaller than that of the second gear 213, so that the rotation speed of the first brush 23 is reduced, and the damage caused by the high rotation speed of the first brush 23 is reduced.
Referring to fig. 3 and 4, the second brushes 24 are disposed on both sides of the second filter screen plate 9, and the second motor 10 is fixedly installed on one side of the second filter screen plate 9 away from the cabinet 1. The second brush 24 is fixedly arranged on the rotating shaft of the second motor 10, and the second brush 24 abuts against the second filter screen plate 9. The second motor 10 is started, and the second motor 10 drives the second hairbrush 24 to rotate to clean the second filter screen plate 9. By keeping the second screen 9 clean, the occurrence of clogging of the second screen 9 with debris is reduced.
The switch button 18 is also used to turn on and off the first motor 61, the second motor 10 and the first fan 5. After the drying oven 11 presses the switch button 18, the first fan 5 is turned off, and the first motor 61, the second motor 10 and the heating pipe 16 are started. After the drying cabinet 11 is separated from the switch button 18, the first fan 5 is started, and the first motor 61, the second motor 10 and the heating pipe 16 are turned off.
After the heating pipe 16 is started, the first fan 5 is turned off, and the first motor 61 drives the fan blades 62 to rotate, so that air outside the cabinet body 1 enters the cabinet body 1 from the first air outlet 7, and then is sequentially discharged from the first air inlet 3 and the second air inlet 4, and accordingly heat of the heating pipe 16 driven by the air is reduced to enter the cabinet body 1.
The embodiment of the application provides a safe fireproof power distribution cabinet for electrical construction, which is implemented by the following principle: the desiccant bed 13 has not absorbed moisture yet, and the weight of the drying box 11 is small, so that the spring 173 drives the drying box 11 to move upward through the support rod 172, and the drying box 11 is separated from the switch button 18. The first fan 5 starts, and the outside air of the cabinet body 1 gets into the cabinet body 1 inside from second air inlet 4 and first air inlet 3 in proper order, and afterwards the air takes away the heat that the components and parts of the internal portion of cabinet 1 give off and discharges from first gas outlet 7 to reduce the internal heat of cabinet body 1, and then improve the fire behavior of switch board.
When air enters the cabinet 1, the air passes through the desiccant bed 13, and the desiccant bed 13 absorbs water vapor in the air, so that the dryness of the air entering the cabinet 1 is improved. The air entering the cabinet body 1 keeps dry, so that the corrosion of components in the cabinet body 1 by water vapor is reduced. The components in the cabinet body 1 are corroded by water vapor, so that the heat emitted by the components is reduced. The heat emitted by the components is less, so that the temperature inside the cabinet body 1 is low, and the fireproof performance of the power distribution cabinet is improved.
More and more moisture is absorbed in the desiccant bed 13, and the weight of the desiccant bed 13 increases, so that the drying box 11 moves downward, the drying box 11 presses the switch button 18, and the first magnet 19 and the second magnet 20 attract each other. The heating pipe 16, the first motor 61 and the second motor 10 are started and the first fan 5 is turned off.
The heating pipe 16 bakes the desiccant layer 13 so that the moisture of the desiccant layer 13 gradually evaporates. The first motor 61 drives the fan blades 62 to send air outside the cabinet body 1 into the cabinet body 1 from the first air outlet 7, and then the air inside the cabinet body 1 is sequentially discharged from the first air inlet 3 and the second air inlet 4, so that the condition that heat emitted by the heating pipe 16 enters the cabinet body 1 is reduced. The first motor 61 drives the first hairbrush 23 to rotate to clean the first filter screen plate 8, and the second motor 10 drives the second hairbrush 24 to rotate to clean the second filter screen plate 9, so that the condition that the first filter screen plate 8 and the second filter screen plate 9 are blocked is reduced.
The moisture in the drying agent layer 13 is evaporated continuously, when the sum of the attractive force between the first magnet 19 and the second magnet 20 and the weight of the drying box 11 is smaller than the force of the restoring deformation of the spring 173, the spring 173 drives the drying box 11 to move upwards, the drying box 11 is separated from the switch button 18, the heating pipe 16, the first motor 61 and the second motor 10 are closed, and the first fan 5 is started. The drying agent layer 13 is used for automatically drying after absorbing more water vapor, so that the condition that the water vapor in the air enters the cabinet body 1 is reduced. The components in the cabinet body 1 are corroded by water vapor, so that the heat emitted by the components is reduced. The heat emitted by the components is less, so that the temperature inside the cabinet body 1 is low, and the fireproof performance of the power distribution cabinet is improved.
