With the help of the clamping knob 25 on the side of the sleeve rod 2 near the bottom, the height and angle of the adapter frame 3 can be fixed, thereby adjusting the height and overall angle of the lighting lamp 4 connected to the bottom of the adapter frame 3; the ear plates 33 at both ends of the bottom of the adapter frame 3 are provided with threaded holes 34, and the positioning screw 5 passing through the holes has a pressure head 52 at the end facing the lighting lamp 4. The pressure head 52 presses into the lighting lamp 4. In the groove 44 on the side of the light lamp 4, the rotating joint 51 on the outside of the positioning screw 5 can be turned to tighten or loosen the light lamp 4, thereby completing the adjustment and fixation of the tilt angle of the light lamp 4. The lamp tube 43 at the bottom of the light lamp 4 not only provides lighting, but also facilitates quick replacement after damage. In terms of power supply, the guide frame 1 is fixed with a power connector 6 through the support plate 63. The wire connector 61 on its side is used to connect to the power supply line. The male connector 62 on the bottom is electrically connected to the female connector 42 at the top of the wire 41 of the light lamp 4 to realize power supply. At the same time, the built-in design of the power connector 6 shortens the length of the wire 41 and avoids the problem of the light lamp 4 being unable to move due to interference from the wire 41 during the movement. Finally, through the coordinated cooperation of various components, the lighting position, height, rotation angle and tilt angle can be flexibly adjusted to meet the diverse lighting needs during the maintenance of the box-type substation.

[0035] In summary, compared with the prior art, this application, by setting a guide frame 1, which is located on the top of the box-type substation, allows the position of the lighting lamp 4 to be adjusted along the guide frame 1, making it convenient to move the lighting lamp 4 to the part to be inspected.
