Summary: | A truss type buoyancy pillar flexible net cage capable of rising and falling along with the water level provided with a damping and anti-swinging plate is characterized in that one section of a truss is sealed with steel plates or composite skin to form a permanent buoyant tank assembly and a variable buoyant tank, the permanent buoyant tank assembly and the variable buoyant tank are completely immersed in water, so that generated buoyancy is larger than 1.3 times of net buoyancy, the variable buoyant tank is provided with a water inlet/outlet pipe valve and an air inlet/outlet pipe valve, and an anti-sinking shoe type heavy aggregate concrete carrier for balancing redundant buoyancy is hung on the bottom of the truss in an inserted mode, so that a truss type buoyancy pillar which can rise and fall is formed; an upper main mooring rope, a lower main mooring rope and a mooring rope are tied onto proper positions of the truss type buoyancy pillar, the upper portion and lower portion of a cultivation net are hung onto the main mooring ropes, the damping and anti-swinging plate is arranged on the bottom of the truss type buoyancy pillar in a tensioned mode, and multi-functional shifting blocks are connected between adjacent stand columns through mooring ropes. The novel net cage is suitable for open sea areas where ocean currents are rapid, and the arrangement of the damping and anti-swinging plate is important for modern ecological and environmentally-friendly mariculture. |
