Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 5, a waterproof incoming line cabinet comprises an inverted V-shaped cabinet top, a left side plate 2 and a right side plate 3 are arranged below two sides of the inverted V-shaped cabinet top in a extending manner, a front panel 1 and a rear panel 4 are respectively arranged below two ends of the cabinet top in the length direction, a water-proof bottom plate 5 is arranged at the bottom, a cabinet door 6 is arranged on one side surface of the water-proof bottom plate 5, a plurality of vent holes 7 are formed in the water-proof bottom plate 5, and a metal protective net is fixed on the surface of the water-proof bottom plate 5 to cover the vent holes 7; supporting columns 9 are arranged at four corners of the bottom of the waterproof bottom plate 5, a waterproof top plate 10 is horizontally arranged at the tops of the left side plate 2 and the right side plate 3, and a ventilation device is arranged on the waterproof top plate 10 to blow air into the cabinet body; the top of the cabinet is provided with a rain-proof ventilation structure.
That is, when the ventilation device arranged on the waterproof top plate 10 blows air downwards, hot air gathered at the top of the incoming cabinet is taken away from the ventilation holes 7 on the waterproof bottom plate 5 at the bottom of the incoming cabinet due to air convection, so that the temperature in the incoming cabinet is reduced, the ventilation is enhanced, and the dryness of the incoming cabinet is kept; the closed cabinet top, the left side plate 2, the right side plate 3, the front panel 1 and the rear panel 4 form a closed whole without an opening, and the waterproof performance is good.
As shown in fig. 3, in order to ensure the inlet wire cabinet to have better waterproof property and ensure its ventilation and heat dissipation, it is better that: the rain-proof ventilation structure is that the cabinet top both ends set up vertical triangular plate body 14 respectively, be equipped with a plurality of ventilation seam 8 in bank on the triangular plate body 14, 8 length direction levels of ventilation seam and opening are down. Specifically, when the ventilating device blows air downwards, outside cold air can be brought into the incoming line cabinet from the ventilating slot 8, the temperature in the incoming line cabinet is further reduced while accumulated hot air is dispersed, and the ventilating slot 8 is arranged on the top of the cabinet, so that the brought cold air is dry and not wet, the incoming line cabinet has good ventilation and heat dissipation, and the moisture-proof effect is achieved; and the opening of the ventilation seam 8 is downward, on one hand, the contact area with cold air is increased, the efficiency of the ventilation device for sucking the cold air is improved, and on the other hand, the opening is used for preventing side rainwater from flowing into the wire inlet cabinet along the opening.
Further, a protective net is arranged on the inner side of the ventilation seam 8. In order to avoid that the sundries (such as leaves, stalks, paper, etc.) are rolled into the ventilating slot 8 by wind.
As shown in FIG. 5, a rain-proof ventilation structure can also be adopted, wherein the rain-proof ventilation structure is a waterproof board 15 respectively arranged at the upper ends of the front panel 1 and the rear panel 4, the upper ends of the two waterproof boards 15 are inclined oppositely and are separated from the cabinet top, and a metal protective net 16 is arranged in the separated area. The waterproof board 15 is fixedly connected with the upper ends of the front panel 1 and the rear panel 4, the left side and the right side of the waterproof board are fixedly connected with the cabinet top, and the upper end of the waterproof board is separated from the cabinet top by a ventilating distance.
The specific structure of the ventilation device to realize the above functions can be various, for example, a heat dissipation fan can be hoisted on the water-proof top plate 10, the heat dissipation fan blows downwards, a through hole is formed in the water-proof top plate 10, and cold air enters through the through hole. More preferably: the ventilation device comprises at least one heat dissipation fan 11, the heat dissipation fan 11 is installed in an installation groove formed in the middle of the waterproof top plate 10, and a dust screen 12 is arranged above the heat dissipation fan 11. That is to say, the heat dissipation fan 11 is directly arranged in the installation groove, and no additional hole needs to be formed in the waterproof top plate 10, so that the integrity of the waterproof top plate 10 is ensured, even if water splashes into the waterproof top plate, the water is only gathered on the waterproof top plate 10 and does not flow downwards, and the waterproof performance of the whole incoming cabinet is improved; the dust screen 12 is arranged above the heat radiation fan 11 to prevent unnecessary damage of foreign matters to the electrical equipment in the incoming cabinet.
the mounting groove can be further optimized as follows: the installation groove is provided with a rubber waterproof sealing strip 13 around the opening. Can prevent that water from flowing into the cubical switchboard along the notch, can also be convenient for fixed mounting cooling fan 11, reduce the vibrations that cooling fan 11 produced when moving.
Furthermore, the contact parts of the cabinet door 6 and the door frame are provided with waterproof sealing strips. The waterproof performance of the cabinet door 6 is improved, the cabinet door can be opened or closed frequently, a gap is formed at the contact position of the cabinet door and the door frame inevitably due to installation or use, and water can flow into the inlet cabinet along the gap.
It should be noted that, in the technical scheme, the cooling fan 11 is an outsourced component, which is also common in the prior art, and the structure and the connection mode of the cooling fan can be selected and installed according to actual situations in specific implementation, so that the structure and the connection mode of the cooling fan do not need to be described in the technical scheme.
Specifically, as shown in fig. 1 to 5, when the heat dissipation fan 11 (of a self-powered type or a type requiring a connection socket) works, air convection in the inlet cabinet is enhanced, external cold air is brought into the inlet cabinet through the ventilation seam 8, the internal temperature is reduced, and hot air gathered at the top of the inlet cabinet is taken away from the ventilation hole 7 on the water-proof bottom plate 5 at the bottom of the inlet cabinet, so that good ventilation and heat dissipation performance of the device is ensured; the left side plate 2, the right side plate 3, the front panel 1 and the rear panel 4 are not provided with openings to form a closed whole, although the triangular plate body 14 of the cabinet top is provided with the ventilation seams 8, the ventilation seams 8 are arranged in rows and have downward openings, rainwater cannot flow into the openings, and even if water splashes into the openings, the rainwater only can float and gather on the waterproof top plate 10 and cannot flow downward; the waterproof plates 15 arranged at the upper ends of the front panel 1 and the rear panel 4 can better ensure the waterproofness of the incoming cabinet, and rainwater on the side surface only can float on the waterproof plates 15 and then fall along the surface of the waterproof plates 15, so that the rainwater cannot flow into the incoming cabinet to soak electrical equipment.
The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalent replacements and are within the scope of the present invention.
