The invention relates to a device and a method for laying and recycling cables. The device comprises a floating drum, a steel cable and a suspension component. A cable storage disc is arranged on the upper portion of the floating drum, and a cable outlet pipeline is arranged in the floating drum. One end of the steel cable is wound and fixed to the cable storage disc, the other end of the steel cable penetrates through the cable outlet pipeline and is fixedly connected with the suspension component, a locating component is fixedly connected to the outer wall of the middle of the suspension component, the locating component is connected with the steel cable, and the suspension component clamps the cable and fixes the cable in a through hole. The method comprises the steps that the initial distance between the suspension component and a device platform is determined according to a catenary analytical calculation formula; a crane places the floating drum, the suspension component and the cable into water at the position with the initial distance away from the device platform; a cable laying ship carries out line navigation at a low speed in the direction away from device platform; a cable winch releases cables continuously along with moving of the cable laying ship. The device and method can lay cables rapidly and conveniently, can recycle cables effectively for reutilization, cost is lowered greatly, and economic performance is improved greatly.
