Description

Technical Field

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

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power 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] At present, when the distribution cabinet is installed outdoors, the gap is only sealed by a sealing gasket when the cabinet door and the cabinet cover are closed. Long-term use can easily lead to a loose fit between the sealing gasket and the gap, resulting in a decrease in the sealing effect. The outdoor environment is harsh and rainy, and it is easy for rainwater to flow into the distribution cabinet from the gap and damage the internal electrical components.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0008] A card frame is fixed on the rear side of the safety door, a wedge-shaped gasket is fixed on the inner wall of the card frame, and a rubber airbag is fixed on the outer surface of the card frame.

[0009] Optionally, the inner wall of the sealing frame is flush with the inner wall of the fixing frame, and the clamping frame is clamped on the outer side of the sealing frame.

[0010] Optionally, a gap is left between the outer surface of the card frame and the inner wall of the power distribution cabinet body, and the inner wall of the wedge-shaped gasket fits with the outer surface of the sealing frame.

[0011] Optionally, the outer surface of the rubber airbag is in contact with the inner wall of the power distribution cabinet body, and a groove is provided on the inner bottom surface of the power distribution cabinet body near the front edge.

[0012] Optionally, a plurality of through openings are equidistantly formed on the inner bottom surface of the groove, and card slots are formed on the rear side of the power distribution cabinet body near the top and bottom edges.

[0013] Optionally, a handle groove is provided on the front side of the safety door near one side edge, and a rubber sleeve is provided on the top of the power distribution cabinet body near one side edge.

[0014] Optionally, the rubber sleeve penetrates into the interior of the power distribution cabinet body, and a plurality of mounting rails are fixed at equal intervals on the rear inner wall of the power distribution cabinet body.

[0015] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0016] 1. In the utility model, a fixing frame is first installed between the inner walls of the power distribution cabinet body, and then a sealing frame is installed on the front side of the fixing frame so that it can be engaged with the card frame on the rear side of the safety door. When engaged, the wedge-shaped gasket on the inner side of the card frame fits with the outer surface of the sealing frame to seal the joint with the outer surface of the sealing frame. The outer surface of the rubber airbag fits with the inner wall of the power distribution cabinet body, and the expansion of the rubber airbag can improve its sealing performance, thereby sealing the joint to prevent the formation of gaps.

[0017] 2. In the utility model, a groove is provided at the bottom of the power distribution cabinet body near the front side, and a plurality of through-holes penetrating to the bottom of the power distribution cabinet body are provided on the inner bottom surface of the groove, so that when the safety door is closed, when the rubber airbag contacts the inner wall at the front edge of the power distribution cabinet body, the water attached to the inner wall is pushed inward, and then discharged from the through-holes of the groove, thereby preventing accumulation inside the closed volume between the rear side of the card frame and the front side of the fixed frame.
