DEVICE AND SYSTEM AFFORDING PROTECTION AGAINST SHORELINE EROSION

摘要

The present invention relates to a submersible device DSP comprising a screen SCR having a plurality of openings, an anchor means AM for anchoring a first end of said screen SCR, here a bottom end, to the ground and means (FM, C1, C2, C3) for holding a second end of said screen SCR, here a top end, up. According to the invention, the holding-up means (FM, C1, C2, C3) include means for adjusting the height of said second end between a minimum height h and a maximum height H. The invention allows the screen SCR to be configured in such a way that it is partially folded, rather than completely collapsed against the ground. This allows the surface area presented to the current to be reduced temporarily particularly with a view to safeguarding the physical integrity of the device in the event of a storm, it being easy for the screen to be redeployed once the storm has passed.
