Storm-resisting nori cultivation raft shelf and cultivation method

Abstract

The invention discloses a storm-resisting nori cultivation raft shelf and a cultivation method. The raft shelf comprises a frame and a cultivation mesh curtain, wherein the frame is a hollow waist drum type frame, the inner edge of the waist drum type frame is provided with the cultivation mesh curtain, the outer edge of the waist drum type frame is uniformly provided with four fixed screw holes,the fixed screw holes are connected with screw rods, and the outer edge of the waist drum type frame is also provided with an anchor ear, thus the waist drum type frame can reduce the stress of storm, basically does not fall apart and deform after being impacted by the storm, and has strong storm-resisting capacity. When cultivation is carried out, because the waist drum type frame is of an integrated structure, the frame is not necessary to be repeatedly assembled when in installation, simultaneously, support legs are saved, various adjacent nori cultivation raft shelves are in bolt connection by using the screw rods when the cultivation is carried out to constitute a conjoined cultivation unit, thus installation is convenient and installation operation difficulty is small; and when being impacted by the storm, because the various adjacent nori cultivation raft shelves are fixed by bolt connection, strike and mutual tangle phenomena are not generated, the cultivation unit has stronger whole storm-resisting capacity and small cultivation risk.

Description

technical field [0001] The invention relates to laver cultivation technology, in particular to a wind and wave resistant laver cultivation raft and a cultivation method. Background technique [0002] As the cultivation area of ​​laver continues to expand and extends from the intertidal zone to the tidal zone, the requirements for the rafts of laver cultivation to resist wind and waves are also getting higher and higher. A conventional laver culture raft frame includes a frame, outriggers and a culture net curtain. The frame is composed of four floating bamboos. Each row of laver culture raft frame is provided with side cables, and the two ends of the side cables are connected with cables. The cables are fixedly connected with anchor piles to achieve a fixed Raft function of laver culture. Authorized notification number is the patent of invention of CN1316875, then discloses to replace side cable with the side rope of cultured net curtain, and side rope is lighter than side...

AI Technical Summary

Problems solved by technology

But above-mentioned seaweed cultivation raft frame with floating bamboo as the frame needs to reassemble the frame every time it is cultivated, fix the legs and the cultivation net curtain, that is, the seaweed cultivation raft frame is reassembled at sea, so the difficulty of offshore installation is high, and it is composed of floating bamboo. The frame is easy to deform and fall apart when it is impacted by a large wind and wave. The frames are fixed with side ropes or side cables, and they are easy to collide and entangle with each other, resulting in falling apart and loss. Therefore, the anti-wind and wave ability is weak and the risk of breeding is high.
