Technical Field
The invention relates to the technical field of marine fishery breeding equipment, in particular to a folding floating type marine fishery breeding platform.
Background
In recent years, with the development of socioeconomic performance of China, the total demand of aquatic products is remarkably increased. As the traditional offshore cage culture faces the development dilemma of water quality deterioration in offshore sea areas, frequent fish diseases and the like, fishery culture begins to develop to deep and open sea areas in order to seek for new development space. The traditional simple net cage cannot adapt to complex stormy wave conditions in open sea, the development direction is gradually developed for the field of ocean engineering and aquaculture equipment, and the design concept of a large-scale floating fishery aquaculture platform is formed.
Most of the floating fishery culture platforms designed and developed at home and abroad currently are large truss-type structures. The floating culture platform provides huge culture water bodies and also causes a plurality of problems in the process of building, transporting and installing. Firstly, different from the slender configuration of a ship, the culture platform has large dimension and approximate length-width dimension, and the width of a dock is higher in the platform construction process, so that most shipyards do not have the construction capability of the culture platform; secondly, the culture platform is large in size, large-area netting has large wind resistance, a large semi-submersible barge is required to be used for dry towing or a large number of towing wheels are required to be used for wet towing in the transportation process, and the transportation cost is high; finally, in the installation process of the culture platform, because the culture platform has a huge volume and needs a certain number of engineering ships for matching, the culture platform can only be installed and positioned in an open sea area, and cannot be arranged in relatively narrow sea area spaces such as narrow bays, offshore wind farms and the like, so that the application range of the culture platform is limited.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 to 4, the invention comprises an upper building 1 and a platform main body, wherein the platform main body is of a polygonal structure formed by a plurality of rod pieces, an upright post 2 is positioned in the center of the platform main body, the upper part of the upright post 2 is connected with the upper building 1, the lower part of the upright post 2 penetrates through a control buoyancy tank 4 and is connected with a lower buoyancy tank 3, a plurality of groups of support rods 6 and connecting rods 5 are uniformly distributed around the upright post 2 at an alpha angle, the angle range of the alpha angle is 30-60 degrees, one end of the connecting rod 5 in a straight rod form is hinged on the top of the control buoyancy tank 4, the other end of the connecting rod 5 is hinged on the middle part of the support rods 6, one end of the support rods 6 in a folding rod form is hinged on the upper part of the lower buoyancy tank 3 of the platform, the other end of the support rods 6 in a folding rod form is connected with the upper building 1 through a cable 7, the support rods 6 in a folding rod form has an included angle beta, the angle range of the beta angle is 120-150 degrees, and a netting 8 is connected between the support rods 6 which are adjacent to each other along the circumferential direction. The control flotation tank 4 is the telescopic type structure of internal diameter and 2 assorted stands, and 4 tops of control flotation tank are the disc, all establish a plurality of recesses on the disc, and the middle part is cylindrical, and the lower part is for invering round platform shape, and the telescopic structure of control flotation tank 4 is inside to be the cavity, holds the ballast water that is used for controlling that the culture platform folds and expands in the cavity. When ballast water is pumped into the control buoyancy tank 4, the control buoyancy tank 4 moves downwards relative to the upright post 2, so that the support rods 6 rotate outwards along the radial direction under the pushing of the connecting rods 5 to realize the expansion of the rod pieces; when the control buoyancy tank 4 is used for emptying ballast water, the control buoyancy tank 4 moves upwards relative to the upright post 2, so that the support rod 6 rotates inwards along the radial direction under the pulling of the connecting rod 5, and the folding of the rod piece is realized.
