Problems solved by technology

Since the length of the anchor chain does not change after it is tightened, the impact load has no buffer and energy dissipation, which makes the cage and mooring foundation prone to damage under the action of large wind and waves

Embodiment Construction

[0028] See attached picture:

[0029] An energy-dissipating net cage anchor chain system, which includes a common anchor chain 19 and an elastic cable 18. The elastic cable 18 is assembled by an internal tie rod, a spring, a barrel, and a bottom sealing plate. The spring 15 is under anchoring force. Large compression and elastic deformation can occur. The cage anchor chain system assembled by connecting the anchor chain 19 and multiple elastic cables 18 end to end has the function of absorbing and consuming part of the impact energy of wind and waves, which is helpful for improving the safety of the cage or anchoring foundation. Sexually favorable.

[0030] The bottom sealing plate 4 of the elastic cable 18 is a circular steel plate, and a connecting hole (bolt hole) 5 is evenly provided on the circumference. A fixed rod 2 is provided at the center of one side of the circular steel plate, and a mooring is provided at the end of the fixed rod 2 Ring 1, the fixed rod 2 and the botto...

Abstract

The invention discloses a net cage anchor chain system with energy dissipation function, including an anchor chain and multiple elastic cables, wherein each elastic cable comprises a barrel, and the barrel is provided with a pull rod, one end of the pull rod extrudes the top plate of the barrel and is provided with mooring ring 1, the other end of the pull rod is on the barrel and is provided with a support plate, the pull rod is sleeved with a spring, both ends of the spring withstand the support plate and barrel top plate, the opening end of the barrel is installed with bottom blanking plate, the center in the outer wall of the bottom blanking plate is provided with a fixing rod, end of the fixing rod is tied with mooring ring 2, and a single anchor chain is distributed with multiple elastic cables whose head and tail are connected. The internal spring of the elastic cable of the invention has bigger and recoverable elastic deformation under anchor force to connect anchor chain and head and tail of multiple elastic cables to form a net cage anchor chain, which can have bigger deformation under wind wave to positively adapt to high frequency vibration and impact load, with energy dissipation function. The net cage anchor chain system can protect net cage and anchoring foundation and improve capacity of resisting wind wave.

Description

[0001] Technical field: [0002] The present invention relates to an anchor chain system for mariculture cages, and more specifically, to a cage anchor chain system with energy dissipation function. [0003] Background technique: [0004] Generally, mariculture cages are connected to the mooring foundation on the seabed by anchor chains. The anchor chain plays the role of mooring and fixing the sea aquaculture cage, and the wind and wave effect of the cage is transmitted to the anchoring foundation through the anchor chain. [0005] Commonly used anchor chains are connected by many steel links. According to the manufacturing method, they are divided into cast steel anchor chains, flash welded anchor chains, and forged anchor chains. According to the link structure, they are divided into gear chains and non-gear chains. The anchor chain can be composed of several "sections", and the sections are connected by chain links or shackles. The strength of the anchor chain is relatively large...
