Description

Technical Field

[0001] The utility model relates to a technical field, in particular to a waterproof structure of an outdoor power distribution cabinet. Background Art

[0002] The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in situations where the load is relatively dispersed and there are fewer circuits. It distributes the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] Although waterproof design has been considered in the existing outdoor distribution cabinet design, the following shortcomings still exist: First, traditional waterproof materials are prone to aging during long-term use, resulting in a decrease in waterproof performance; second, the existing waterproof structure design cannot completely prevent moisture penetration, especially under the vibration and impact generated during equipment operation; third, during the use of the equipment, the distribution cabinet door needs to be opened frequently due to maintenance and overhaul, which will also affect the waterproof performance. Utility Model Content

[0004] The utility model aims to provide a waterproof structure of an outdoor power distribution cabinet to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waterproof structure of an outdoor power distribution cabinet, comprising a cabinet body, an equipment rack and a filling layer, two groups of waterproof covers are fixedly installed on both sides of the exterior of the cabinet body, air inlets are opened on both sides of the cabinet body, a waterproof groove is arranged at the lower part of the interior of the cabinet body, two groups of equipment racks are installed inside the cabinet body, a door is installed on the front side of the cabinet body through a hinge, a sealing ring is installed on the back of the door, the cabinet body comprises an outer liner, an inner liner and a filling layer, and a filling layer is arranged between the outer liner and the inner liner.

[0006] When the device is used outdoors for a long time, the outer and inner shells are made of metal materials with corrosion resistance and anti-aging properties, and a double-layer design is adopted with a filling layer material filled inside, so that the device has excellent waterproof, dustproof and aging resistance. When water enters the cabinet, the waterproof groove can be used to collect and export the moisture that may enter the cabinet. When the device is ventilated and dissipated through the air inlet, the waterproof cover can protect the air inlet to prevent water from entering the interior of the cabinet through the air inlet. Due to the needs of maintenance and overhaul, the device allows the door to be opened and closed frequently without affecting the waterproof performance.

[0007] Preferably, the filling layer is made of polyurethane foam material.

[0008] Polyurethane rigid foam is a new type of synthetic material with thermal insulation and waterproof functions. It has low thermal conductivity and good waterproof performance, which can effectively improve the waterproof ability of the device.

[0009] Preferably, a handle is installed on the front side of the door, and a window is installed inside the door.

[0010] The handle can provide a gripping position for the staff's hands, making it convenient for the staff to grip the handle to open the box door.

[0011] Preferably, a magnetic ring is installed on the front of the cabinet, and a mounting hole is opened inside the equipment rack.

[0012] The magnetic ring has a certain magnetic attraction ability. The magnetic attraction force generated by the magnetic ring on the cabinet can improve the sealing of the door and the cabinet when they are closed.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] When the utility model is used outdoors for a long time, the outer liner and the inner liner are made of metal materials with corrosion resistance and anti-aging performance, and a double-layer design is adopted, and the filling layer material is filled inside, so that the device has excellent waterproof, dustproof and aging resistance. When water enters the cabinet, the waterproof groove can be used to collect and guide out the moisture that may enter the cabinet. When the device is ventilated and heats up through the air inlet, the waterproof cover can protect the air inlet to prevent water from entering the interior of the cabinet through the air inlet. Due to the needs of maintenance and overhaul, the device allows the box door to be opened and closed frequently without affecting the waterproof performance. BRIEF DESCRIPTION OF THE DRAWINGS
