AI Technical Summary
Technical Problem
The process of laying DC cables for photovoltaic strings is inefficient, requiring a lot of manpower and time, resulting in high labor intensity and low efficiency.
Method used
A cable-laying tool was designed, including a spindle, cable reel, rotary bearing, rotating rod, and guide pulley structure. The cable is pulled out of the cable reel through a support frame, reducing the number of operators and improving cable-laying efficiency.
Benefits of technology
Two people can complete the cable laying task, reducing labor intensity, improving laying efficiency, shortening the construction period, avoiding cable damage, and applicable to cable reels of different diameters.

Abstract
The application provides a pay-off tool for a photovoltaic string DC cable. The pay-off tool comprises a main shaft, a cable reel, a rotary bearing, a reel moving rod, a support frame, a first guide pulley and a second guide pulley. The main shaft is vertically arranged, the main shaft is arranged in the axial center of the cable reel, the cable reel is configured to wind the cable, the inner ring of the rotary bearing is sleeved and fixed to the main shaft and the rotary bearing is located above the cable reel, the reel moving rod is connected to the outer ring of the rotary bearing, the support frame comprises a vertical arm and a horizontal arm which are connected to each other, the vertical arm is connected to the outer ring of the rotary bearing, the first guide pulley is installed at the end of the horizontal arm, the second guide pulley is installed above the support frame, and the cable passes through the first guide pulley and the second guide pulley in sequence. The cable in the cable reel is withdrawn through the support frame, the number of operators can be reduced during the whole pay-off process, the labor intensity is reduced, and the pay-off efficiency can be effectively improved.
