Embodiment

[0014] Example: refer to Figure 1 to Figure 3 , a double-pipe raft frame, including a rope 4 with an anchor, wherein: the rope 4 is connected to a pair of floating pipes 1 arranged in parallel; the floating pipe 1 is an airtight hollow structure; the lower side of the floating pipe 1 is equipped with a sinking mesh 3; The end of the floating pipe 1 is connected with a control device capable of inflating or draining the floating pipe 1; a balance floating ball 11 is moored on the floating pipe 1 between the mesh sheets 3. The mesh 3 can effectively mount shellfish for intensive cultivation. Adopting the inflatable floating tube 1 can resist waves better, and can drain water and sink to avoid wind and waves when the wind and waves are relatively large. The long and narrow structure is more conducive to reducing the traction force of the directional water flow. The combination of the advantages of the two greatly improves the safety. The balance float 11 can play a pulling ef...

Abstract

The invention discloses a double-tube raft frame which comprises ropes which are provided with anchors. The ropes are connected with a pair of floating tubes which are arranged in parallel. Each floating tube is in a closed hollow structure. Sink type mesh pieces are arranged at the lower side of each floating tube. A control device which is capable of charging air or discharging the air for the floating tubes is connected with the end portion of each floating tube. Balance floating balls are arranged on the floating tubes between the mesh pieces in a berthing mode. The mesh pieces are capable of effectively hanging and loading shellfish to conduct concentrated aquaculture. The double-tube raft frame is capable of well resisting waves by adopting the inflatable floating tubes. When stormy waves are heavy, the double-tube raft frame is capable of draining off water and sinking to avoid the stormy waves. The long and narrow structure is relatively beneficial for reducing tractive effort of directional water current. When the floating tubes are sunk at the bottom, the balance floating balls play a role of pulling and are capable of preventing the floating tubes from rupturing due to overlarge gravity. The double-tube raft frame has the advantages of being low in cost, resistant to high flow rate and high waves, firm in structure, high in aquaculture capacity and good in water flow performance.

Description

technical field [0001] The invention relates to an offshore aquaculture facility, in particular to a double-pipe raft frame. Background technique [0002] Shellfish and algae are the main species of marine aquaculture in my country, and the output of the two accounts for about 90% of the total output of marine aquaculture in my country. It is estimated that 70,000 tons of inorganic nitrogen, 8,000 tons of inorganic phosphorus, and more than 1.2 million tons of carbon can be removed from coastal waters every year by harvesting shellfish, which is very important for controlling eutrophication in coastal waters and global carbon dioxide. The greenhouse effect played an important role. It can be said that the proper development of shallow sea shell algae farming can not only provide a large amount of high-quality seafood for humans, but also effectively control marine eutrophication and prevent red tides. It has significant ecological and environmental benefits and is a win-win...
