Conical Storm-Resistant Deep-Sea Cage Net Design

2025-03-26

Targeted Design Background

Developed specifically for high-wave regions like the South China Sea (Hainan, Zhanjiang), addressing:

  • Net tearing during typhoons (annual losses >¥10M)

  • PE net corrosion (traditional nets require replacement every 5 years)

  • Space compression from strong currents (effective volume <60%)

Revolutionary Structural Design

1)Inverted Conical Storm-Resistant Structure

  • Top diameter > Bottom (e.g., Φ30m→Φ25m):
     Lowers center of gravity (resists waves ≥12m)
    Reduces wave impact by 35% (tested in wave tanks)

  • PE Twisted Knotless Net:
    10+ year lifespan 
    Anti-snag design (damage rate <0.5%/year)

2) South China Sea-Specific Enhancements
      Mooring System:

       8-point radial anchor chains (each anchor ≥3 tons)

       Elastic buffer joints
       Anti-Corrosion Treatment:

       UV + anti-fouling dual coating (5-year efficacy)
