Self-elevating box-type culture platform

Abstract

The invention discloses a self-elevating box-type culture platform which comprises a culture net cage and a structural ship body surrounding the periphery of the culture net cage, wherein the structural ship body comprises a lifting device and a locking system, pile legs penetrate through the structural ship body and are slidably connected with the structural ship body through the lifting device, and pile shoes are arranged at the bottoms of the pile legs; and a locking structure matched with the locking system is arranged on the upper portion of the culture net cage, and a guide structure used for moving up and down along the pile legs of the structural ship body is arranged on the lower portion of the culture net cage. The culture platform has the functions of capable of resisting typhoon, being autonomously positioned and installed on the sea, improving the safety of living and operation of culture personnel and workers, having a large feed storage space, reducing the platform supply period, reducing water in the net cage by independently lifting the net cage, facilitating offshore fish collection and netting cleaning and replacement, protecting the culture net cage during construction and dragging and the like.

Description

technical field [0001] The present invention relates to an offshore culture platform, more specifically, to a self-elevating box-type culture platform. Background technique [0002] Due to the large truss structure assembled by steel pipes, the cages of conventional offshore farming platforms are difficult to be dragged by tugboats when the cages are moved at sea. If the cages are not operated properly, the cages will be deformed or even damaged. [0003] Conventional fixed offshore aquaculture platforms usually have no buoyancy in order to reduce construction costs. After the platform is completed, it needs to be transported from the construction location to the aquaculture sea area through the joint operation of super large offshore floating cranes and semi-submersible ships. Then it is necessary to drive piles by piling boats to fix the farming platform to the sea; the transportation and offshore installation costs of the farming platform are very high.

AI Technical Summary

Problems solved by technology

Then it is necessary to drive piles by piling boats to fix the farming platform to the sea; the transportation and offshore installation costs of the farming platform are very high

[0004] Conventional floating offshore farming platforms need to be fixed to the seabed through anchors and anchor chains, but the platform itself cannot lay positioning anchors and anchor chains. It must be completed by a special anchor ship, and the laying of anchors and anchor Very long time, resulting in very high cost of offshore installation

[0005] After the conventional fixed farming platform is fixed at sea, it cannot be dismantled and moved to other sea areas normally, and repeated farming operations cannot be realized

[0006] During the farming operation of the conventional floating offshore farming platform, although the platform is fixed on the sea through the mooring positioning system, the platform is still in a floating state, and the platform will sway under the influence of waves, which affects the living and safety of the operators.

[0007] When a typhoon comes to a conventional floating offshore farming platform, either the cages are raised or the cages are submerged underwater. This is not only very troublesome to operate, but also changes the living area of ​​the fishes in the water. This has a great impact on the farmed fish, and the most serious one is the death of fish due to the change of air pressure
