- a plurality of first buoyancy devices 20 can be evenly distributed along the length direction of the dynamic cable 10; or a plurality of first buoyancy devices 20 can be a group, and each group of first buoyancy devices 20 can be evenly distributed along the length direction of the dynamic cable 10. Distribution, the first buoyancy devices 20 in each group are arranged in sequence.
- the number of the first buoyancy devices 20 can be flexibly set according to the use requirements, and there is no specific limit here.
- the buoyancy power generation device 81 and the adjacent second buoyancy device 30 are connected through the second connection device 50.
- Such a structure can limit the activity range of the second buoyancy device 30 and avoid the second buoyancy force. Excessive range of movement of the device 30 will cause the linear shape of the dynamic cable 10 to change too much, and even cause serious pulling on the fixing device 82 , which is beneficial to keeping the linear shape of the dynamic cable 10 in a stable state.
