Technical Field

[0001] The utility model belongs to the technical field of cable reels, in particular to a cable reel device for quickly laying out cables. Background Art

[0002] The photovoltaic inverter connects the photovoltaic array and the power grid, controls the charging and discharging of the battery, and can convert AC and DC. It is one of the main components of the photovoltaic power generation system and plays a key role in the long-term stable operation of the photovoltaic power station. The component small line refers to the 1*4mm between the photovoltaic panel and the inverter. 2 The cable drum for storing small component wires can contain several thousand meters or even tens of thousands of meters of small component wires. It takes a long time to manually rotate the small component wires one by one and then put them in the designated area. Therefore, a laying structure is used when laying cables.

[0003] Cable laying is a common electrical installation process, especially in large-scale construction projects, power facility construction and renovation projects. Traditional cable laying methods are usually completed by manual pulling or simple mechanical devices. This method often has the following problems:

[0004] Due to the lack of effective cable laying auxiliary equipment, the cable is prone to jamming during the laying process, resulting in low laying efficiency. When laying cables over longer distances, the unlaid portion of the cable is prone to sag, which not only affects the laying operation but may also cause safety hazards. Utility Model Content
