Description

Technical Field

[0001] The utility model relates to the technical field of power distribution panels, in particular to a direct current power distribution panel with a lightning protection mechanism. Background Art

[0002] The DC distribution panel is also called the DC operating power supply system, which can provide DC power for power operating equipment. There are many electronic components installed in the distribution panel. When the distribution panel is set up outdoors, it is easy to be struck by lightning during thunderstorms, causing damage to the internal electronic components. The lightning rod installed on the existing DC distribution panel is fixed at a fixed height and directly installed on the top of the DC distribution panel. When it is windy outdoors, it is very easy to blow up garbage such as plastic bags and cloth and finally hang on the lightning rod, which is easy to cause a fire during lightning protection. Utility Model Content

[0003] The utility model provides a DC power distribution panel with a lightning protection mechanism. The lifting lightning rod can be retracted in non-thunderstorm weather to play a protective role.

At this time, the lightning rod can play a lightning protection role. When the lightning rod is connected to electricity to avoid lightning, the lightning is transmitted to the grounding wire through the lightning rod, and then transmitted to the ground through the grounding wire. The lifting lightning rod can be retracted in non-thunderstorm weather to play a protective role.

[0007] Preferably, the lifting assembly includes a motor, a threaded rod connected to the bottom of the motor output shaft, and a slider screwed to the threaded rod.

[0008] Through the above solution, the motor can drive the threaded rod to rotate, so that the sliding block can move in the vertical groove.

[0009] Preferably, a through hole is formed on the top outer wall of the rain shield.

[0010] Through the above solution, the insulating column and the lightning rod can pass through the through hole during the rising process.

[0011] Preferably, the slider is slidably connected to the inner wall of the vertical groove, a threaded through hole is opened on the outer wall at the top of the slider, and the slider is threadedly connected to the threaded rod.

[0012] Through the above solution, when the threaded rod rotates, the sliding block is limited by the inner wall of the vertical groove and does not rotate with the rotation of the threaded rod, but moves on the inner wall of the vertical groove.

[0013] Preferably, both ends of the top of the rain shield are inclined structures.

[0014] Through the above scheme, water flow is convenient.

[0015] Preferably, the motor is connected to a control switch via a wire, and the control switch is connected to an external power source via a power line.

At this time, the lightning rod can play a lightning protection role. When the lightning rod is connected to electricity to avoid lightning, the lightning is transmitted to the grounding wire through the lightning rod, and then transmitted to the ground through the grounding wire. The lifting lightning rod can be retracted in non-thunderstorm weather to play a protective role. BRIEF DESCRIPTION OF THE DRAWINGS
