Description
technical field [0001] The invention relates to the technical field of cable transmission, in particular to a constant tension control device for shore power cable transmission. Background technique [0002] When the ship is docked, the ship's power system is mainly powered by the port. In the past, most of the cables were used to connect the ship's power system and the electric piles on the shore manually. When the ship left the port, the cable was manually retracted. Damage the cable, causing safety hazards. Therefore, the cable conveying device is usually used to convey the cable from the reel to the designated position of the ship. However, due to the full load and empty load of the ship, the rise and fall of the tide and other reasons, the position of the ship will change, which will cause excessive tension or relaxation of the cable, which will affect the life of the cable and the reliability of the cable conveying device. Security risks. Contents of the invention ...
