Description

Technical Field

[0001] This utility model belongs to the field of power construction technology, and in particular relates to a lighting device for power construction. Background Technology

[0002] Power construction refers to a series of tasks involving the construction, installation, maintenance, and repair of power equipment and facilities. Power engineering involves multiple stages such as planning, design, construction, supervision, and acceptance. By maintaining and repairing power equipment, the power supply and safe operation of power equipment can be guaranteed. However, when carrying out power construction-related operations at night or in conditions of insufficient light, appropriate lighting devices are required for illumination.

[0003] Traditional lighting devices mainly consist of a fixed rod and a telescopic support rod. A light is installed on the top of the support rod. Adjustment holes are provided on the fixed rod and the telescopic rod. By fixing bolts into the adjustment holes, the height of the lighting device can be adjusted, thereby adjusting the lighting position of the light.

[0004] However, the structure of the aforementioned traditional lighting devices is relatively simple, and they can only be adjusted to a single height. Due to the limitations of the illumination angle and the obstruction between different power equipment, the effective coverage area of ​​the light is limited, and they can only provide sufficient lighting for local areas. They lack flexibility in adjustment, so there is an urgent need to design a lighting device for power construction to solve the above problems. Utility Model Content
