Considering when meeting the rainwater weather, falling on ground and the rainwater that splashes can enter into cabinet 11 through exhaust hole 18, the side that sets up exhaust hole 18 at cabinet 11 is provided with curb plate 16, leave the clearance between cabinet 11 and the curb plate 16, connect through a plurality of flourishing water board 19 that is curved between cabinet 11 and the exhaust hole 18 simultaneously, make curb plate 16 fix in one side of cabinet 11, install gauze 17 in one side of curb plate 16 simultaneously, when meeting rainy day air, lid 2 shelters from the top of cabinet 1, the rainwater that falls on ground and splashes is blockked by gauze 17 at first, the rainwater that sees through gauze 17 is blockked by curb plate 16 again, so just avoid the rainwater to enter into the possibility in the cabinet 11.
Meanwhile, in order to improve the heat dissipation effect of the device, a plurality of holes are formed in the side plate 16, external rainwater falls on the water containing plate 19 through the holes in the side plate 16, when weather is hot, water in the water containing plate 19 cools the cabinet 11 through evaporation, so that the overall cooling effect of the device is enhanced, meanwhile, when the weather is hot, the side plate 16 blocks external sunlight, sunlight can not directly irradiate on the cabinet 11, a gap between the side plate 16 and the cabinet 11 can be used as a chamber for isolating temperature, when air flows through the gap between the side plate 16 and the cabinet 11, heat on the cabinet 11 can be carried away, and therefore the heat dissipation speed of the cabinet 11 is accelerated.
The cover 2 comprises a middle block 21 and shielding plates 22 fixed on two sides of the middle block 21, the middle block 21 is placed at the top of the cabinet 11, two ends of the shielding plates 22 extend outwards, one end of each shielding plate 22 extends out of the space occupied by the cabinet 11, the shielding plates 22 are convenient to shield the cabinet 11, two sides of the middle block 21 also extend outwards, the cover 2 covers the top of the cabinet 1 completely, rainwater cannot fall into the space between the cabinet 1 and the cover 2 when the rainy day is met, meanwhile, the shielding plates 22 are fixed at four corners of the top of the cabinet 11 through screws, the cover 2 is fixed at the top of the cabinet 1, and stability of the cover 2 in normal working is ensured.
In order to enable the heat generated in the cabinet 11 to be rapidly discharged to the outside, the top of the cabinet 11 is communicated with the outside, a ventilation space through which the air flows passes is reserved between the shielding plate 22 and the top of the cabinet 11, the ventilation space is communicated with the outside of the cabinet 11, hot air in the cabinet 11 and the air flow outside the cabinet 11 can pass through the ventilation space, in order to enable the air flow to move better in the ventilation space, a guide cambered surface 24 is arranged on the lower side of the shielding plate 22, the guide cambered surface 24 is arc-shaped, one end of the guide cambered surface 24, close to the middle block 21, extends downwards, when the air flow is blown by the outside, the air flow flows towards the inside of the cabinet 11 along the track of the guide cambered surface 24 after entering the ventilation space, the air flow enters the cabinet 11, and the air flow entering the inside of the cabinet 11 blows the electric appliance inside the cabinet 11, and the heat generated during working is blown away, the downward air flow is discharged through the exhaust hole 18 of the lower half part of the cabinet 11, so that the heat is carried away from the device in a normal weather mode of carrying away the heat from the cabinet through the inside when the weather is met.
When no air flow exists outside, hot air in the cabinet 11 moves upwards, and is guided by the guiding cambered surface 24 to be discharged to two sides of the cabinet 11, heat is prevented from accumulating in the cabinet 11, the whole heat dissipation of the device is ensured, meanwhile, in order to enable the device to dissipate heat rapidly in a windless state, an electric fan is arranged in the cabinet 11 and on the side wall of the cabinet 11, air flow blown by the electric fan moves transversely in the cabinet 11, namely moves along the horizontal direction, heat generated on an electric appliance is blown away, and then the air with the heat moves upwards or downwards, so that the heat leaves the device.
Considering that when there is airflow flowing outside, there may be large impurities such as small plastic bags, leaves and other impurities brought into the cabinet 11, and in order to avoid the entry of impurities, a plurality of bars 15 are symmetrically fixed on the top of the cabinet 11, gaps are left in front of the plurality of bars 15, the airflow entering the ventilation space enters the cabinet 11 through the gaps between the bars 15, and large particle impurities carried in the airflow are blocked by the bars 15 (the large particle impurities are particles with a size larger than the gaps between the two bars 15), so that the impurities are blocked under the condition of ensuring normal heat dissipation of the device.
In order to increase the amount of external airflow entering the cabinet 11, an upper guide plate 12 is fixed on the cabinet 11 at the lower side of the shielding plate 22, the upper guide plate 12 guides part of external airflow to flow towards the ventilation space, when the air is in windy weather, rainwater possibly falls onto the upper guide plate 12 and enters the cabinet 11 through the upper guide plate 12, so that electric appliances in the cabinet 11 are soaked, a water blocking strip 14 extending towards the ventilation space is fixed at one end of the upper guide plate 12, one end of the water blocking strip 14 is inclined upwards, and the inclined water blocking strip 14 blocks the rainwater falling onto the upper guide plate 12 and guides the airflow to flow towards the shielding plate 22, so that the rainwater is prevented from entering the cabinet 11.
When the external air flow direction is not on one side of the cabinet 11 but the air flows from the adjacent side of the shielding plate 22, in order to ensure that the air flow enters the cabinet 11, side guide grooves 26 inclined inwards are arranged at positions, close to the bottoms, of the two ends of the middle block 21, the side guide grooves 26 guide the external air flow to the cabinet 11, and side guide plates 13 inclined towards the upper side of the cabinet 11 are fixed at positions, corresponding to the side guide grooves 26, on the cabinet 11, the side guide plates 13 block external rainwater, so that heat in the cabinet 11 is guaranteed to be taken away.
