Problems solved by technology

Intense axial movement may cause buckling or bending at the top of the buoyancy zone of the cold sea water pipe, and crush failure. If the top of the cold sea water pipe exhibits extreme tension, the cold sea water pipe may break
At the same time, the cold sea water pipe is subject to the impact of sea water flow at any time in the sea water, and it has to bear a large lateral force, which will also make the cold sea water pipe bend and deform

Abstract

The invention provides a cold seawater pipe operation system based on temperature difference energy power generation. The operation system comprises a platform device, a water taking pipe column, and a plurality of lifting devices arranged in the circumferential direction of the water taking pipe column; the platform device is provided with a moon pool for lowering the water taking pipe column; each lifting device comprises a first pulley mechanism fixed to the platform device; one end of a telescopic mechanism is connected with the first pulley mechanism; a second pulley mechanism is connected with the other end of the telescopic mechanism; a pull rope is wound on the pulleys of the first pulley mechanism and the second pulley mechanism and is connected with the water taking pipe column; and when the water taking pipe column ascends and descends, the second pulley mechanism can move between a first position and a second position under the interaction of the pull rope and the telescopic mechanism, and an acute angle is formed between the direction of the pull rope between the lifting device and the water taking pipe column and the axis direction of the water taking pipe column. According to the specification, the phenomena of bending, twisting and the like of the water taking pipe column during use can be avoided.

Description

technical field [0001] The present application relates to the technical field of ocean thermoelectric power generation, and in particular to a cold seawater pipeline operation system based on thermoelectric power generation. Background technique [0002] Ocean temperature difference energy is one of the most stable and high-density energy sources in ocean energy, and has good development and utilization value. Ocean temperature difference power generation is to use the temperature difference between the shallow and deep layers of seawater and the different heat sources of temperature and cold to generate electricity. The cold water pipeline is an important part of the ocean temperature difference power station, and it is the only channel for deep cold seawater to enter the temperature difference power generation system. [0003] The cold sea water pipe is connected with the offshore platform device, and is in a suspended state when the cold sea water pipe is lowered, workin...
