When the rain falls outside, the influence of the rain on the water inlet of the switch cabinet is different due to different rainfall, when the rainfall is small, the rainwater cannot enter the cabinet body 1 through the gap of the shutter blades 4, when the rainfall is large, the rainwater is easy to splash or shower into the switch cabinet from the bottom of the shutter due to the splashing of the rainwater or wind power, so that the humidity inside the switch cabinet is influenced, the normal use of the switch cabinet is influenced, when the rainfall is large, a certain amount of rainwater can be dynamically remained inside the collecting box 9 all the time during the drainage period due to the small aperture of the drainage pipe 3, under the action of gravity, the collecting box 9 starts to move downwards, meanwhile, the bottom end of the collecting box 9 extrudes the first spring 11 downwards through the pressing block 12, so as to drive the vertical plate 13 to move downwards, the rack 30 on the vertical plate 13 is meshed with the transmission gear 23 for transmission, so that the shutter blades 4 are closed, and the rainproof effect is achieved, and the larger the outside rainfall is, the smaller the included angle formed between the bottom of the louver blade 4 and the outer wall of the cabinet body 1 is, so that the self-adaptive angle adjustment along with the outside rainfall can be realized, and the rainwater is prevented from entering the inside of the cabinet body 1 when the outside rainfall is larger.
When shutter blade 4 closes, the inside whole of cabinet body 1 is in comparatively confined state, and the inside radiating effect of cubical switchboard can worsen, opens driving motor 27 this moment, drives the inside air flow speed of flabellum 28 high-speed rotation improvement cubical switchboard through driving motor 27, increases inside thermal heat exchange, improves the heat exchange efficiency of the less gap department of shutter to reduce shutter blade 4 and close the radiating influence to the cabinet body 1.
When rain stops, because there is not the rainwater at collecting box 9 top and continuously flows in, the inside rainwater of collecting box 9 can be ceaselessly discharged from drain pipe 3, along with the reduction of the whole weight of collecting box 9, first compression spring 11, second compression spring 18 upward movement resets collecting box 9, and simultaneously, drive riser 13 upward movement, rack 30 through riser 13 drives drive gear 23 and rotates, make shutter blade 4 open, improve cubical switchboard and external air heat exchange efficiency, carry out better heat dissipation, shutter blade 4's automatic opening reset has been realized.
Furthermore, in order to prevent the top of the collecting box 9 from being influenced by the increase of the whole weight of the collecting box 9 due to the falling of other sundries such as branches and the like, the top of the collecting box 9 is designed to be of a trapezoidal structure, when the external sundries fall onto the top of the collecting box 9, the external sundries can easily slide down under the action of gravity or wind power, the external sundries are effectively prevented from directly scattering onto the collecting box 9, the sundries can be prevented from entering the collecting box 9 to influence the use through the filter screens 2 arranged around the top end of the collecting box 9, meanwhile, the drain pipe 3 is prevented from being blocked, the drain rate of the drain pipe 3 can be further adjusted according to the valve, and the dynamic water storage amount of the collecting box 9 can be adjusted in the actual use process to further adjust the opening and closing degree of the shutter blades 4.
It should be noted that the invention is an outdoor rainproof heat-dissipation switch cabinet, when the rainfall is small, the rainwater dropped in the collection box 9 is discharged to the outside of the cabinet body 1 through the drain pipe 3, when the rainfall is continuous and the rainfall is large, because the aperture of the drain pipe 3 is small, during the drainage period, a certain amount of rainwater can be remained in the collection box 9, under the action of gravity, the collection box 9 starts to move downwards, at the same time, the bottom end of the collection box 9 extrudes the first spring 11 downwards through the pressing block 12, so as to drive the vertical plate 13 to move downwards, the rack 30 on the vertical plate 13 is in meshing transmission with the transmission gear 23, so that the louver blade 4 is closed, so as to play a rainproof role, after the rainfall stops, the water in the collection box 9 is slowly reduced to the whole through the drain pipe 3 and is discharged out of the cabinet body 1, the vertical plate 13 is bounced under the action of the second compression spring 18, so as to move upwards, the rack 30 on the vertical plate 13 is in meshing transmission with the transmission gear 23, thereby driving the second chain wheel 20 to rotate, the second chain wheel 20 drives the first chain wheel 15 to rotate under the action of the chain 21, the first chain wheel 15 drives the belt pulley 24 to rotate through the first rotating shaft 22, the louver blades 4 are opened under the action of the second rotating shaft 29, meanwhile, the driving motor 27 at the bottom end inside the cabinet body 1 drives the fan blades 28 to rotate through the third rotating shaft 16, heat generated by electric appliances inside the cabinet body 1 is blown into the second cavity 17 through the heat dissipation holes, and is finally discharged through the louver blades 4, when the rainfall is very low, rainwater enters the collection box 9 through the filter screen 2 at the top end of the collection box 9 and is finally discharged through the drain pipe 3, at the moment, the first compression spring 11 above the vertical plate 13 slowly lifts the collection box 9 through the pressing block 12, the rack 30 on the vertical plate 13 keeps the louver blades 4 in an opened state under the combined action of the transmission gear 23, the chain 21, the first chain wheel 15 and the second rotating shaft 29, through this setting, the radiating effect of the cabinet body 1 is improved, the damage of the electric appliance in the cabinet body 1 is avoided, and the working efficiency is improved.
