Problems solved by technology

Most of the current sail telescopic devices adopt the scissor type, multi-stage screw nut superimposition, and hydraulic lifting rod to fold and deform the sail. The above devices are relatively bulky and take up a lot of space, which does not meet the lightweight design of marine vehicle deformation devices. principle, and the folding rate is limited

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, a folding sail with a variable area and a large folding rate, the folding sail includes: a skeleton component 1, a flexible skin 2, and a wire drive component 3; wherein the flexible skin 2 is consolidated on the skeleton On the component 1 , the line drive component 3 is connected with the skeleton component 1 .

[0030] Such as figure 2 As shown, the skeleton assembly 1 includes: 1 piece of driving skeleton 11 , 4 pieces of follow-up skeletons 12 , 13 , 14 , 15 , and 1 piece of fixed skeleton 16 . The driving skeleton 11 is located at the top of the skeleton assembly 1, the fixed skeleton 16 is located at the bottom of the skeleton assembly 1, and the four follow-up skeletons 12, 13, 14, 15 are sequentially located between the driving skeleton 11 and the fixed skeleton 16; all skeletons 11, 12 , 13 , 14 , 15 , 16 are connected to...

Abstract

The invention discloses a single-degree-of-freedom foldable and deployable wing sail, comprising a skeleton component, a flexible skin and a wire drive component; wherein, the flexible skin is fixed on the skeleton component, and the wire drive component is connected with the skeleton component; The driving frame, the follower frame and the fixed frame are arranged in sequence from top to bottom; the follower frame is composed of a first aluminum alloy rod and a first carbon fiber rod; the driving frame includes a second aluminum alloy rod and a second carbon fiber rod , an unfolding line fixing shaft, a folding line fixing shaft, and a rotating disk; the fixing frame includes a third carbon fiber rod, a first threaded rod, a connecting rod assembly and a second threaded rod. The invention changes the area of ​​the wing sail by unfolding different numbers of skeletons to adapt to different wind speeds and wind directions on the sea surface, so that the wing sail has a better thrust performance and a relatively stable sailing attitude, and in addition, all the skeletons are folded together to achieve a larger folding rate, so that the craft can be converted from sail drive mode to propeller propulsion or dive sailing motion mode.

Description

technical field [0001] The invention relates to a wing sail for a marine vehicle with multi-movement modes, in particular to a single-degree-of-freedom foldable wing sail with an adjustable area and a large folding rate. Background technique [0002] At present, in order for marine vehicles to conduct long-term on-site observation of the air-sea interface, it is necessary to use natural energy wind energy as the driving force to enable the vehicle to have long-term navigation capabilities on the surface. In addition, when the vehicle needs to switch to propeller propulsion or In the submersible mode, the wing sail needs to have a larger folding rate. Most of the current sail telescopic devices adopt the scissor type, multi-stage screw nut superimposition, and hydraulic lifting rod to fold and deform the sail. The above devices are relatively bulky and take up a lot of space, which does not meet the lightweight design of marine vehicle deformation devices. principle, and the...
