Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with a circuit protection mechanism. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet, which 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 the occasions where the load is relatively dispersed and there are fewer circuits. The motor control center is used in the occasions 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. Various protective devices such as fuses (fuses) to prevent short circuits and air switches to prevent overloads can be conveniently placed in the distribution cabinet to protect the lines and electrical equipment.

[0003] When the existing power distribution cabinet is in use, the top of the cabinet is easily deformed when subjected to force, and the accumulation of rain and snow can easily affect the normal use of the power distribution cabinet. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a power distribution cabinet with a circuit protection mechanism, comprising a cabinet body, a symmetrically arranged hinged seat fixedly connected to the top of the cabinet body, a bearing plate hingedly connected to the two hinged seats, a symmetrically arranged rubber seat fixedly connected to the bottom end of the bearing plate, a mounting plate fixedly connected to the side wall of the cabinet body, a mounting box fixedly connected to one side of the top of the mounting plate, a motor fixedly installed inside the mounting box, a transmission rod fixedly connected to the output end of the motor, a symmetrically arranged support plate fixedly connected to the side wall of the cabinet body, a guide rod fixedly connected between the two support plates, an active rack slidably connected to the guide rod, a transmission frame fixedly connected to the bottom end of the active rack, a rotating rod rotatably connected to the side wall of the cabinet body corresponding to the top position of the active rack, a lifting rod fixedly connected to the middle position of the rotating rod, and a driven gear fixedly connected to the rotating rod corresponding to the position of the active rack.

[0006] As a preferred solution of the utility model, the active rack is located at the bottom end of the driven gear, and the active rack is meshingly connected with the driven gear.

[0007] As a preferred solution of the utility model, the lifting rod is located at the bottom end of the bearing plate, and the top end of the lifting rod abuts against the bottom end of the bearing plate.

[0008] As a preferred solution of the present utility model, the transmission rod is transmission-connected to the transmission frame.

[0009] As a preferred solution of the present utility model, a base is fixedly connected to the bottom end of the cabinet.

[0010] Compared with the prior art, the beneficial effect of the power distribution cabinet with a circuit protection mechanism of the utility model is that: when clearing rain and snow, the cooperation of the active rack and the driven gear can make the various mechanisms linked to push the bearing plate upward, so that the rain and snow slide down from the top of the bearing plate, preventing the rain and snow from accumulating on the top of the bearing plate for a long time and affecting the normal use of the power distribution cabinet, and the linkage of the various mechanisms makes the motor output end rotate in the same direction all the time during operation to realize the up and down rotation of the bearing plate, which can ensure the service life of the motor and be more stable.
