Embodiment 1

[0033] Such as figure 1 As shown, the adjustable depth seaweed breeding floating bed includes a main anchor cable 2 and a seaweed breeding floating bed, wherein the upper end of the main anchor cable 2 is connected to the main floating ball 1 floating on the water surface, and the lower end is connected to a stable structure located on the seabed. The cable is provided with three sets of chain links 3 for fixing the floating bed for increasing seaweed; There is a bottom net 7, the cables in the main anchor cable 2 pass through the bottom net 7, and there is a purse net 8 around the buoyant frame 6; the bottom of the buoyant frame 6 is connected with a counterweight by a stay rope system, the counterweight system is connected to the link 3 on the cable; the seaweed breeding floating bed is connected to the link 3 of different heights through the counterweight system to adjust the predetermined water layer.

Embodiment 2

[0042] The floating bed constructed in the above-mentioned embodiment 1 is applied to the kelp seaweed in the sea area of ​​the remote sea island:

[0043] In this example, in December 2011, a seaweed breeding floating bed with a diameter of 4 meters was placed in the deep water area of ​​Rizhao Qiansan Island, 37 nautical miles away from the shore (water depth 25 meters). One kelp seedling rope is fixed on the surface, and the transplanting density of kelp is about 110 per plant, with an average initial length of 30.7 cm per plant. The floating bed is fixed at a depth of 10 meters underwater (the high tide period of the big flood). After breeding for two months, the growth of algae was monitored, and the algae grew well, the color was normal, and the length of the algae was 1.3m. The main body of the floating bed was in an upright state underwater without damage.

[0044] The results of the examples show that the facilities of the present invention can be used to increase s...

Abstract

The invention relates to a macrophytic algae aquaculture facility suitable for open type deep waters, in particular to an adjustable deep sea algae aquaculture floating bed, which substantially comprises a main anchor cable, a sea algae aquaculture floating bed and a weight system, wherein a mooring rope of the main anchor cable consists of a main float ball, a center circle, a chain ring, a lower circle, a rotating ring and a dropstone, and the sea algae aquaculture floating bed comprises a buoyancy framework, a bottom net, a purse net, a center circle, an oblique stay cord, a weight system and a guide plate. The adjustable deep sea algae aquaculture floating bed is a movable type floating bed frame, wherein the bottom portion of the adjustable deep sea algae aquaculture floating bed is provided with the bottom net, the middle portion of the bottom net is provided with a round iron ring, and the periphery of the movable type floating bed frame is inwardly obliquely provided with a circle of purse net. The weight system comprises a weight hanging rack, a weight block and a position card bolt. The adjustable deep sea algae aquaculture floating bed uses a double-buoyancy system, and can be guaranteed in an upright posture underwater through own bigger buoyancy of the movable type floating bed frame, can be accurately fixed on a scheduled water layer through a buoyancy system of the main anchor cable, and is more convenient to adjust the scheduled water layer by integrally arranging the adjustable deep sea algae aquaculture floating bed and the weight system in a micro buoyancy state.

Description

Technical field: [0001] The invention relates to a large-scale algae breeding facility suitable for open deep-water sea areas, in particular to a floating bed with adjustable depth for seaweed breeding. Background technique: [0002] The sea areas used by mariculture in my country are mainly concentrated within the 20-meter isobath. The area with a water depth of more than 20 meters is far from the shore, so it is less affected by land-based pollution, the water flow is smooth, and the water quality is clean. It is an important area for shallow sea habitat restoration and fishery resource recovery. The construction of large kelp beds is the key to repairing damaged marine habitats and effectively restoring fishery resources. Large algae in shallow sea areas mostly adopt raft culture. The advantage is that it is easy to manage, but the disadvantage is that the suitable sea area is relatively shallow, and the cultured algae live in the upper water body. Affected by wind and ...
