The existing high and low voltage distribution cabinets are simply opened with heat dissipation holes to dissipate heat for the high and low voltage distribution cabinets, and the heat dissipation efficiency is low. When the temperature of the electrical appliances inside the high and low voltage distribution cabinets is too high, it will cause damage to the electrical appliances and even the risk of fire. The heat dissipation practicality of the high and low voltage distribution cabinets is poor; some of them are cooled by fans, and dustproof nets are installed at the air inlets. However, rainwater can easily enter the distribution cabinet through the dustproof net on rainy days, causing damage to the internal electrical appliances; for this reason, the present application proposes a high and low voltage distribution cabinet with good heat dissipation function.

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a high and low voltage power distribution cabinet with good heat dissipation function, including:

[0021] The power distribution cabinet 1 has exhaust ducts 2 installed at the lower ends of both sides of the power distribution cabinet 1. A retaining net can be installed in the exhaust duct 2 to prevent flying insects from flying into the power distribution cabinet 1.

[0022] A heat dissipation component used for the inside of the power distribution cabinet 1; the heat dissipation component includes a V-shaped plate 3 fixed to the upper end of the power distribution cabinet 1 and arranged inverted, the V-shaped plate 3 is welded to the upper end of the power distribution cabinet 1, and a stable connection between the V-shaped plate 3 and the power distribution cabinet 1 is ensured by welding; the rear side of the V-shaped plate 3 is sealed, and a triangular sealing plate 8 is fixed to the rear side of the V-shaped plate 3, and the sealing plate 8 is connected to the V-shaped plate 3 by welding.

[0023] The front side of the V-shaped plate 3 is blocked by the filter plate 4, the bottom of the filter plate 4 is against the upper end of the distribution cabinet 1, and the back side of the filter plate 4 is against the triangular plate 10; the filter plate 4 is limited by three limiting mechanisms, the limiting mechanism includes a short rod 6 installed on the V-shaped plate 3 and the distribution cabinet 1, a limiting block 5 is rotatably installed on the short rod 6, a torsion spring is installed between the limiting block 5 and the short rod 6, and the upper end of the filter plate 4 is slidably connected to the bottom of the V-shaped plate 3; the filter plate 4 is not easy to move through the support and limitation of the distribution cabinet 1 and the triangular plate 10, the torsion spring enables the limiting block 5 to be positioned, and the limiting block 5 is against the front side wall of the filter plate 4, so that the filter plate 4 can be limited and it is not easy to separate from the distribution cabinet 1.

[0024] When the filter plate 4 needs to be disassembled and cleaned, the staff cooperate to rotate the limit block 5 so that it is not opposite to the filter plate 4, and the filter plate 4 can be removed for cleaning; in order to ensure the filtering effect of the filter plate 4, a dustproof net, such as a nylon net, etc., can be installed on the inner or outer side of the filter plate 4 to improve the dust filtering effect.

[0025] A triangular plate 10 is fixed to the upper end of the distribution cabinet 1, and a spacer is provided between the V-shaped plate 3 and the distribution cabinet 1, and the spacer is arranged opposite to the lower end of the triangular plate 10, so that rainwater entering through the filter plate 4 falls on the triangular plate 10, and the rainwater flows to the spacer on the triangular plate 10, and the rainwater can be discharged.

[0026] A fixed fan 9 is provided through the upper end of the triangular plate 10 and the power distribution cabinet 1. An air inlet tube 11 is installed at the air inlet end of the fan 9. A rain shield tube 7 is fixed to the bottom of the V-shaped plate 3. When the fan 9 is working, the external air enters the V-shaped plate 3 through the filter plate 4, and the air enters the air inlet tube 11 through the rain shield tube 7, and finally blows into the power distribution cabinet 1. The air is discharged through the exhaust tube 2, so that the air circulation is realized, and the heat inside the power distribution cabinet 1 can be dissipated;

[0027] Since the rain shield tube 7 is arranged on the outside of the air inlet tube 11, the inner diameter of the rain shield tube 7 is larger than the outer diameter of the air inlet tube 11, and the bottom of the rain shield tube 7 is lower than the upper end of the air inlet tube 11, rainwater will be blocked by the rain shield tube 7 after passing through the filter plate 4, preventing rainwater from entering the distribution cabinet 1.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
