The embodiment of the application provides an electric construction is with implementation principle of safe type fire prevention switch board does: the desiccant bed 13 does not absorb moisture yet and the cabinet 11 has a small weight, so that the spring 173 moves the cabinet 11 upward through the support rod 172, and the cabinet 11 is separated from the switch button 18. First fan 5 starts, and the air of the 1 outside of the cabinet body gets into the 1 inside of the cabinet body from second air inlet 4 and first air inlet 3 in proper order, and later the air takes away the heat that the components and parts of the 1 inside of the cabinet body gived off from first gas outlet 7 and discharges to reduce the heat of the 1 inside of the cabinet body, and then improve the fire behavior of switch board.
When air enters the cabinet 1, the air firstly passes through the desiccant layer 13, and the desiccant layer 13 absorbs moisture 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 the components inside the cabinet body 1 by water vapor is reduced. The components and parts in the cabinet body 1 are corroded by water vapor, so that the heat emitted by the components and parts is reduced. The heat that components and parts distribute is few to make the temperature of the 1 inside of cabinet body low, and then improve the fire behavior of switch board.
The moisture absorbed in the desiccant layer 13 is increased, the weight of the desiccant layer 13 is increased, and the drying container 11 is moved downward, the switch button 18 is pressed by the drying container 11, and the first magnet 19 and the second magnet 20 are attracted to each other. The heating duct 16, the first motor 61 and the second motor 10 are started and the first fan 5 is switched off.
The heating pipe 16 bakes the desiccant layer 13, thereby gradually evaporating the moisture of the desiccant layer 13. The first motor 61 drives the fan blades 62 to send the 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 discharged from the first air inlet 3 and the second air inlet 4 in sequence, so that the heat emitted by the heating pipe 16 is reduced and the situation inside the cabinet body 1 is avoided. 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 blockage of the first filter screen plate 8 and the second filter screen plate 9 is reduced.
The moisture in the desiccant layer 13 is evaporated continuously, and when the sum of the attraction force between the first magnet 19 and the second magnet 20 and the weight of the drying box 11 is less than the force of the spring 173 restoring the deformation, 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 turned off, and the first fan 5 is started. The drying agent layer 13 can automatically dry after absorbing much water vapor, so that the situation that the water vapor in the air enters the cabinet body 1 is reduced. The components and parts in the cabinet body 1 are corroded by water vapor, so that the heat emitted by the components and parts is reduced. The heat that components and parts distribute is few to make the temperature of the 1 inside of cabinet body low, and then improve the fire behavior of switch board.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
