Description
Technical Field
The invention relates to a mariculture platform, in particular to a far-sea tubular pile purse net culture platform.
Background
Fish is a main source of the best quality protein of human beings in the 21 st century, and with the rapid exhaustion of offshore fishery resources in China, the fishing and the trans-culture become the correct direction for fishery development. Since China became the first country with the culture quantity exceeding the fishing quantity in the world in 1988, the aquatic product yield continuously occupies the first world in 28 years.
China is a big breeding country but not a strong breeding country. The method is characterized in that the aquaculture industry in China is still in a low-level development stage, still belongs to a resource consumption type industry, has high energy consumption, high pollution and low yield, has increasingly serious pollution and ecological damage to offshore areas and excessive extraction of underground water resources, has insufficient equipment and informatization degrees, has low quality of cultured aquatic products, sometimes has aquatic product safety problems, cannot meet the vigorous demand of the society on high-quality commercial fishes, has insufficient fine breed development and popularization strength, has a fine breed coverage rate of only about 30 percent, is far away from the fine breed coverage rate of 70 percent in developed aquaculture countries, and becomes a bottleneck problem restricting the development of the fishery in China.
The marine aquaculture seine in China is mostly a shallow sea seine which is mainly distributed in the sea areas of Zhejiang, fujian, guangdong and the like, and has the problems of high aquaculture density, low water body exchange rate, serious water body eutrophication, frequent diseases, high death rate and the like. The open reports about purse net culture in foreign mariculture are few, and the research and demonstration of the open-sea large-scale tubular pile purse net three-dimensional ecological high-efficiency culture technology based on the northern sea area of China are not reported yet.
The impact on the purse seine is huge because the far sea bottom water flow acting force is large. The purse seine fixed connection of the large open sea tubular pile purse seine culture platform is very important. The lower end of the purse net of the existing ocean farming platform generally adopts mechanisms such as a counterweight stretching anchor chain and the like to enable the bottom end of the purse net to be contacted with the sea floor surface. In a large-scale open sea tubular pile purse net culture platform, the common netting and the connection mode thereof have obvious defects, mainly the joint strength of the lower end of the purse net and the sea bottom is poor, and the purse net can be lifted from the bottom end by the water flow of the sea bottom to cause cultured organisms to escape.
According to different life habits, part of fishes feed on the water surface, and part of fishes (such as cynoglossus semilaevis) feed on the seabed. Therefore, the bait feeding device is necessary to be arranged at the seabed part. Because the impact force of the water flow on the seabed is large, the common bait feeding device installed on the seabed as the prior art is very complicated to operate and high in construction cost, and the common bait tank is difficult to meet the requirement of resisting the water flow impact.
A large open sea pipe pile purse net culture platform is a multifunctional aquaculture system independent in the sea area. The platform needs to transport related equipment, baits, fry, adult fishes and the like between land and a culture platform by means of ships, and the platform needs to be hoisted by a crane no matter transported in or out, so that the crane is very necessary to be installed in a platform system. The existing ocean farming platform is not suitable for directly installing a crane generally, because the base at the rear end of the boom bears large force and the force is uneven in all directions when the crane works, the structure of the platform can be directly influenced or even damaged, and the work safety is difficult to guarantee.

The invention adopts the L-shaped purse net, and is connected with the pipe piles below the seabed through the seabed connecting ropes; the bottom net is ensured to be attached to the sea bottom surface through the iron chain. When the connecting rope at a certain position of the seabed is invalid, the bottom net plays a role in supplementary protection. The purse seine is firm and reliable in connection and can effectively prevent cultured organisms from escaping.
The main breeding area of the invention can be also provided with a bait blocking dense net. The horizontal direction of the bait blocking dense net is vertical to the main flowing direction of the water flow in the culture sea area. When in use, the floating baits are thrown to the upstream side of the water flow of the bait blocking dense net. Therefore, bait loss from the net holes of the purse net can be effectively reduced.
The bottom bait trough consists of the dense net and the thick rope which are made of flexible materials, and can well meet the requirement of water flow impact resistance. During construction and installation, the dense net and the thick rope of the bottom bait groove can be connected to the bottom net of the inner ring purse net in advance to form the bottom bait groove, and the bottom bait groove and the inner ring purse net are installed on the seabed together. The problem of wasting time and energy that the installation bottom bait silo alone caused has been avoided.
According to the invention, the extension tubular pile is arranged on the outer side of the outer tubular pile, the reinforcing tubular pile is arranged between the extension tubular pile and the outer tubular pile, and the connecting flange is located and installed right above the reinforcing tubular pile through the reinforcing connecting piece and the group of reinforcing rib plates. The stress of each direction of the suspension arm is transmitted to each tubular pile and the connecting piece through the reinforcing connecting piece, the connecting flange and the reinforcing rib plate, and the downward stress is transmitted to the seabed, so the mechanism has the outstanding characteristics of firmness, stability, impact resistance and the like, and can effectively ensure the stable installation and safe operation requirements of the crane.
All the parts are made in a land modularized mode and then assembled into the open sea tubular pile purse net culture platform at sea. On one hand, the method can greatly improve the offshore installation efficiency and reduce construction waste; on the other hand, various components are produced and manufactured in an intensive mode, so that large-scale and standard marine ranches can be built in multiple sea areas conveniently, and the popularization and application of patent technologies are facilitated.
