Abstract

The invention discloses a folding and unfolding device of a foldable catamaran. The device comprises a front folding and unfolding device, a rear folding and unfolding device, two floating bodies, an operation platform, and a front base and a rear base which form the foldable catamaran. The operation platform and the floating bodies are connected through retracting and releasing mechanisms, unfolding and folding can be carried out, the stability of water surface navigation can be improved when the device is unfolded, the size is smaller when the device is folded, and carrying, transportation and storage are convenient. The folding and unfolding device is composed of symmetrical hinge four-bar mechanisms, the kinematics of the folding and unfolding device meets the condition that a hinge four-bar mechanisms have determined motion, the folding and unfolding system can form a truss structure after being unfolded, and the folding and unfolding device has high strength and rigidity. All the assemblies of the whole ship body can be detached, and installation, debugging, transportation and storage are convenient. The operation platform is free in design, a user can carry out refitting design on the operation platform according to own requirements, and the requirements of different application fields of the ship can be met.

Description

technical field [0001] The invention belongs to the field of ships, in particular to a retractable device for a catamaran. Background technique [0002] At present, more and more catamarans appear in people's field of vision. It has the characteristics of high stability, good maneuverability, and good stealth, and it is constantly developing in the direction of large-scale and rapid development. The unique structure of the catamaran makes its transverse dimension much larger than that of ships of the same tonnage, which makes the space utilization rate of the catamaran lower during transportation and storage. [0003] However, most catamarans have a one-piece hull. When this type of ship is for home use, special vehicles are required for transportation, which increases expenses; when it is for commercial use, larger catamarans will have transportation difficulties and even traffic restrictions. Contents of the invention [0004] The purpose of the present invention is to...
