Description

Waterproof electrical cabinet

technical field

The utility model relates to an electric cabinet, in particular to a waterproof electric cabinet.

Background technique

For electrical cabinets installed outdoors, such as power savers placed on the roadside, the adaptation to the environment is an important performance that such electrical cabinets need to have. For example, in rainy weather, the electrical cabinet needs to have a certain waterproof function. , which can not only increase the service life of the electrical cabinet, but also have a certain protective effect on the electrical equipment in the electrical cabinet, and can prevent the occurrence of dangerous accidents.

At present, most of the electrical cabinets installed outdoors do not have rainproof protection facilities, especially there are no protective devices at the air inlet and outlet of the ventilation device to prevent rainwater from entering, which greatly reduces the service life of the electrical cabinet and increases Reduce the maintenance and use cost of the electrical cabinet.

Utility model content

The technical problem to be solved by the utility model is to provide a waterproof electrical cabinet to solve the problems that the electrical cabinet cannot be waterproof and has a low service life when it works outdoors.

In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a waterproof electrical cabinet, including a housing, the housing is provided with an air inlet and an air outlet, and a first downward opening is provided on the outside of the air inlet. A water shield is provided outside the air outlet with a second water shield that opens downward.

As an improvement, the air inlet is arranged at the lower part of the rear wall of the casing, and the air outlet is arranged at the top wall of the casing;

As a further improvement, a first ventilation fan is installed at the air inlet;

As a further improvement, a second ventilation fan is installed at the air outlet;

As a further improvement, a partition for placing electrical components is provided inside the housing, and a third ventilation fan is provided on the partition;

As a further improvement, protective nets are fixedly installed at the air inlet and the air outlet.

Due to the adoption of the above technical solution, the waterproof electrical cabinet includes a casing, the casing is provided with an air inlet and an air outlet, and a first water shield with an opening downward is provided outside the air inlet. The outer side of the air outlet is provided with a second water shield with the opening downwards. Through the water shield, rainwater can be prevented from entering the electrical cabinet through the air inlet and outlet, so as to ensure that the electrical equipment in the cabinet is not invaded by rainwater, etc., improving all The working environment of the electric cabinet, thereby greatly improving the service life of the electric cabinet and electrical equipment.

Description of drawings

Accompanying drawing is the structural representation of the utility model embodiment.

Detailed ways

As shown in the drawings, the waterproof electrical cabinet includes a housing 1, the housing 1 is provided with an air inlet 2 and an air outlet 3, the air inlet 2 is arranged at the lower part of the rear wall of the housing 1, and the air outlet 3 is provided On the top wall of the housing, the air inlet 2 and the air outlet 3 are fixed with a protective net 7, the protective net 7 prevents debris from entering the cabinet, and protects the electrical equipment in the cabinet from damage On the outside of the air inlet 2, a first water shield 4 with an opening downward is provided. The first water shield 4 is a square with an opening below and an inclined top surface, and is fixedly installed on the housing 1 On the rear wall of the electrical cabinet, the first water shield 4 prevents rainwater from entering the electrical cabinet from the air inlet 2 in windy and rainy days to corrode and damage the electrical equipment in the electrical cabinet; on the outside of the air outlet A second water-shielding cover 5 with an opening downward is provided, and the bottom surface of the second water-shielding cover 5 is larger than the top surface of the housing 1 to cover the air outlet 3 to prevent water or rain from entering.

The first ventilation fan 21 is installed at the air inlet 2, and the first ventilation fan 21 is an air intake fan, and the air passes through the opening of the first water shield 4 by the first ventilation fan 21. Into the electrical cabinet; the second ventilation fan 31 is installed at the air outlet 3, and the second ventilation fan 31 is an exhaust fan, which discharges the air that completes the heat exchange in the electrical cabinet to the outside of the cabinet; The inside of the housing 1 is provided with a partition 6 for placing electrical components, and the partition is provided with a third ventilation fan 61, and the third ventilation fan 61 is also an exhaust fan. The air circulation is smoother, the convection of the air inside and outside the cabinet is accelerated, the temperature of the electrical components in the cabinet is reduced, and the normal operation of the equipment is guaranteed.

The working environment of the electrical cabinet working outdoors is very harsh, especially in rainy weather, this embodiment has greater advantages, its second water shield 5 can keep out the rain, and the first water shield 4 can prevent the rain from being blown by the wind. Blow into the cabinet, thus improving the working environment of the electrical cabinet.
