Semi-submersible offshore fishing ground platform with lightweight frame structure

Abstract

The invention provides a semi-submersible offshore fishing ground platform of a lightweight frame structure. The semi-submersible offshore fishing ground platform comprises a main body frame, a control room arranged at the top of the main body frame and netting installed on the side wall and the bottom of the main body frame. The main body frame comprises a central stand column, a plurality of external stand columns which are uniformly arranged around the central stand column, an upper horizontal support, a lower horizontal support, an upper chord pipe, a middle chord pipe, a lower chord pipeand an inclined support; the center stand column and the exteranl stand columns are the same in structure and each comprise an upper float bowl arranged on the upper portion, a middle stand column fixedly connected with the bottom of the upper float bowl and a lower float bowl fixedly connected with the bottom of the middle stand column. The fishery platform is light and stable in structure, the inclination angle can be controlled within 20 degrees in a normal operation state, the motion amplitude does not exceed 1 / 5 of the diameter of the breeding platform, and safety and stability of the breeding platform can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of fishery platforms, in particular to a semi-submersible offshore fishery platform with a lightweight frame structure. Background technique [0002] Existing farming equipment is mostly used in offshore waters, and its ability to resist extreme wind, waves and currents is relatively weak. In addition, the density of offshore aquaculture cages is high, and the exchange of water bodies is weakened, causing eutrophication of water bodies and causing damage to the ecological environment. Traditional gravity cages lack the support of rigid structures, and are prone to deformation under the action of large water currents and waves, resulting in reduced living space for fish. Therefore, in order to solve the above problems and promote the sustainable development of aquaculture, aquaculture in deep and open seas is the only way to develop from near seas to far seas. The invention is a frame-type semi-submersible ...
