Description

Technical Field

[0001] The present invention relates to the field of ice slurry storage, and in particular to an ice slurry storage device and a control method for an offshore floating power generation platform. Background Art

[0002] Deep-sea floating power generation platforms are favored because they do not occupy land and because there are abundant offshore wind, solar and wave energy resources. However, how to effectively utilize the converted electrical energy is a problem faced by deep-sea floating power generation platform technology. On-site consumption through ice slurry cold storage is one of the important technical routes. The stored ice slurry can be used for ice addition for offshore fishing boats and cooling for islands and reefs. Among them, efficient storage of ice slurry is a key issue in this technical route.

[0003] At present, most traditional ice storage methods use rigid containers, such as patents CN214620207U (grant number), CN201810438536 (application number), CN213273316U (grant number), etc., all of which use containers made of rigid materials. However, due to differences in the use environment, transportation costs, and installation costs, the use of rigid ice storage devices on deep-sea floating power generation platforms will cause costs to rise sharply. From the installation point of view, flexible ice storage devices do not have to occupy the effective use area of ​​the floating platform, greatly improving its practicality. Although there are patents such as medical ice bags and related research, medical ice bags are very different from floating power generation platform ice storage devices in terms of magnitude, use, and control strategy. At present, no related devices for ice storage on offshore floating platforms have been found, and there is also a lack of related research on the control methods of ice slurry input and output. Summary of the invention
