Description
Technical Field
The invention relates to a variable-structure wave self-adaptive catamaran, and belongs to the field of ship mechanical equipment.
Background
The marine stable platform is an important ship facility and provides stable operation space for various operation equipment of ships. As the search pace of the ocean increases, the demand for stable platforms at sea increases. For example, the safety of unmanned aerial vehicle takes off and land when unmanned aerial vehicle is in coordination with the battle, the normal work of equipment such as sonar when submarine topography surveys, the normal operation of relevant equipment when salvaging at sea all urgently need the highly stable of platform. However, the wind and the wave always influence the navigation and the operation of the ship, so that the development and the construction of the offshore stable platform are challenging.
In order to reduce the swing of the ship caused by wind waves, besides the anti-rolling device arranged on the ship, the stability of the ship body can be improved to a certain extent due to the optimized design of the ship structure. Catamarans are more stable than conventional monohull vessels, and the area of the deck platform is much larger than a monohull vessel of equivalent displacement. The application of the front edge technology in the catamaran along with wave self-adaptation at present ensures that the catamaran has higher stability and can keep the stability of the deck platform even under the condition of wave-following shaking.
Because the structure of the wave self-adaptive catamaran is fixed, and the load of a common platform is smaller, the length and the width of the hull can be increased only when a large load is required, and the cost of additionally manufacturing one catamaran can be greatly increased.
Therefore, how to design a catamaran with stronger wave self-adaptation and capability of changing the occupied space of the hull and meeting the requirements of load equipment becomes a technical problem to be solved.

The two groups of hydraulic deformation mechanisms 3 are respectively arranged at the front end and the rear end of the deck platform 4, namely, the two ends along the direction of the transverse axis of the catamaran. Each group of hydraulic deformation mechanisms 3 is connected with the two spring shock absorbers 2 through the left and right support bases, and the whole structure is symmetrically distributed along the roll axis.
