Inflation and exhaust type buoy lifting shellfish culture raft frame

Abstract

The invention relates to a culture raft frame for scallop and mussel culture, which is suitable for artificial culture of marine products including shallow sea scallops and mussels. The culture raft frame comprises a large culture stalk, inflation and exhaust type buoys, a culture cage, pulleys, an inflation and exhaust hose and an air valve core sealing valve, wherein the large culture stalk is connected with the buoys by regulating cables, one buoy is corresponding to a regulating cable, a universal lock catch is arranged below each buoy, a water depth graduation mark is arranged on each regulating cable, the inflation and exhaust type buoys are uniformly arranged on the large culture stalk and connected with the large culture stalk by cables and cable padlocks, water charging and drainage holes are uniformly arranged below the inflation and exhaust type buoys along the circumferential direction, and double pulleys are respectively arranged at both ends of the large culture stalk. The raft frame can realize upward floating and sinking of the large culture stalk within a depth range of 2-12m under the sea level, thereby satisfying various requirements of the cultured marine products on water depth and water temperature in different sea conditions and different seasons.

Description

technical field [0001] The invention relates to an inflatable and exhaust type buoy elevating shellfish culture rack, which is especially suitable for the elevating culture raft rack for shallow sea scallop and mussel culture. Background technique [0002] Raft farming technology is widely used in the cultivation of oysters, scallops and macroalgae in countries such as Europe and the United States. Since the perfection and maturity of kelp raft farming technology in the 1950s in my country, it has developed into a culture involving algae (kelp, seaweed, etc.). , Asparagus, Eucheuma, Geliflower, Hijiki), shellfish (scallops, oysters, mussels), abalone, ginseng, sea urchin, crabs and other varieties of raft farming.

Problems solved by technology

[0003] The equipment used in the known raft culture technology is inconvenient to adjust the position of the raft culture stalk in the water during the process of putting in the seedlings of seafood to the mature harvest of the product. For the cultured seafood, the water temperature and water depth When there are special requirements, it will not be able to meet the breeding requirements very well, which will affect the yield rate of seafood harvest.
