Abstract
Description
Technical Field
[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a power distribution cabinet with multiple rainproof designs. Background Technology
[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.
[0003] Because the power distribution cabinet contains a large number of electronic devices that generally need to be powered, it is necessary to protect the cabinet from rain. If the cabinet is tightly sealed, it will affect heat dissipation. Therefore, ventilation holes need to be designed. However, under normal circumstances, rainwater will seep through the ventilation holes. Rainfall is usually accompanied by strong winds, which will blow the rainwater into the ventilation holes. Therefore, a power distribution cabinet with multiple layers of rain protection is needed, which can also ensure heat dissipation. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a power distribution cabinet with multiple rainproof designs.
[0005] This utility model provides a power distribution cabinet with multiple rainproof designs, including: an outer shell and a switch door installed on the outer shell; first rainproof components are provided on both sides of the outer shell; a second rainproof component is also provided inside the outer shell for cooperating with the first rainproof components; a collection component for collecting water resources is also provided on the outer shell; a shielding component for shielding the top of the outer shell is also provided on the outer shell, and the shielding component is also provided with a locking member for locking the switch door.
[0006] Preferably, the first rainproof component includes a rain shield installed on the side of the housing. The rain shield is installed on the side of the housing by bolts, and the rain shield has heat dissipation strips that are inclined.
[0007] Preferably, the second rainproof component includes a first shield and a second shield installed on the inner wall of the housing. The first shield is located between the rainproof plate and the second shield, and the first shield and the second shield are arranged at intervals. Heat dissipation components are provided on the first shield and the second shield.
[0008] Preferably, the heat dissipation component consists of a first heat dissipation hole on a first shield and a second heat dissipation hole on a second shield, with the first heat dissipation hole and the second heat dissipation hole arranged at intervals.
[0009] Preferably, the collecting component is a collecting plate installed on the bottom wall of the inner shell, and the shell is also provided with a water outlet channel, which is at the same horizontal plane as the collecting plate.

[0011] Compared with related technologies, the power distribution cabinet with multiple rainproof designs provided by this utility model has the following beneficial effects: the rain shield can effectively prevent rainwater from entering the casing from the side, but some rainwater will reach the first shield through the heat dissipation strip. The first shield can effectively block the rainwater. The rainwater will reach the second shield through the first heat dissipation hole on the first shield. Not much rainwater will reach the second shield. At this time, the second shield will effectively block the rainwater. The rainwater will flow into the collection component. The excess rainwater will flow away through the water outlet channel.
[0012] The design of the shielding components can effectively block rainwater from the top of the casing;
[0013] The design of the first and second heat dissipation holes, water outlet channels, and heat dissipation strips can effectively dissipate heat from the inside of the casing. Attached Figure Description

[0026] The second rainproof component includes a first shield 7 and a second shield 8 installed on the inner wall of the outer casing 1. The first shield 7 is located between the rainproof plate 2 and the second shield 8. The first shield 7 and the second shield 8 are arranged at intervals.
