The application discloses a cold
water pipe for ocean
temperature difference energy power generation, a lowering anti-swing device and a method, and relates to the technical field of ocean
temperature difference energy power generation. The cold
water pipe comprises an inner layer sleeve and an outer layer sleeve coaxially arranged, and has an accommodating cavity between the inner layer sleeve and the outer layer sleeve. The two ends of the accommodating cavity are blocked, and the accommodating cavity is filled with
thermal insulation material. The top end and the bottom end of the cold
water pipe are respectively connected with an
upper joint and a lower joint. The top end of the
upper joint is provided with an upper annular protrusion, and the bottom end of the lower joint is provided with a lower annular protrusion. The upper annular protrusion and the lower annular protrusion are connected by a clamp. The two ends of the cold water
pipe are connected by the clamp, which not only has a simple connection mode, but also has higher connection strength and can improve the connection efficiency. The lowering anti-swing device can obviously reduce the shaking amplitude of the cold water
pipe to be connected, and make the shaking direction and the shaking frequency of the cold water
pipe to be connected and the cold water pipe at the
wellhead of the ship body consistent, thereby reducing the connection difficulty of the two cold water pipes.
