Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a cross-sectional view of a heat-dissipating louver.
Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the ventilation duct of the distribution box comprises a cover body 2 covering a heat dissipation opening 5 of the distribution box 1, wherein heat dissipation shutters 3 and ventilation holes 4 are respectively arranged on two sides of the front surface of the cover body 2, a water outlet is arranged at the bottom of the cover body 2, and a plug is arranged at the water outlet.
The 1 thermovent 5 of block terminal is higher than the cover body 2 inner chamber bottom surfaces, even water gets into the cover body 2 like this, also can't get into block terminal 1 through 1 thermovent 5 of block terminal.
The heat dissipation port 5 of the distribution box 1 is provided with a dustproof net, so that dust prevention is facilitated.
The heat dissipation shutter 3 is located on the right side of the front face of the cover body 2 and is opposite to the heat dissipation port 5 of the distribution box 1, and when water is sprayed, water energy facing the heat dissipation port 5 of the distribution box 1 can be blocked by the heat dissipation shutter 3.
The heat-dissipating louver 3, as shown in fig. 2, includes a window 7, an inner louver 8, and an outer louver 6. The outer louver 6 is positioned outside the window 7, the top edge of the outer louver 6 is fixed with the top edge of the window 7, the bottom edge of the outer louver 6 is flush with the bottom edge of the window 7, a gap is reserved between the bottom edge of the outer louver 6 and the bottom edge of the window 7, the inner louver 8 is positioned inside the window 7, the top edge of the inner louver 8 is fixed with the top edge of the window 7, the bottom edge of the inner louver 8 is higher than the bottom edge of the window 7, and a gap is reserved between the bottom edge of the inner louver 8 and the bottom edge of the window 7.
The heat dissipation shutter 3 with the structure has stronger water retaining effect, sprayed water is firstly blocked by the outer shutter 6, part of splashed water splashes into gaps between the outer shutter 6 and the window 7, the direction of the splashed water is from bottom to top, and the water hits the inner shutter 8 to form water flow which flows into the cover body 2 and cannot enter the distribution box 1; meanwhile, the bottom edge of the inner louver 8 is higher than that of the window 7, so that normal heat dissipation is not influenced.
The utility model discloses cover 1 thermovent 5 of block terminal, when the water spray, the cover body 2 can be advanced to water at most, can't get into block terminal 1, has guaranteed distribution safety.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
