[0002] At present, the level of ship greening is increasing day by day, and countries are actively developing various energy-saving and emission-reduction technologies. Among them, with the research and development of information technology and modern sail theory, sail boosting, as the oldest energy-saving technology, has returned to the stage of green application in shipping. In recent years, rigid airfoil sails have been demonstrated and applied on ultra-large VLCC oil tankers. The sail-boosted "Kaili Wheel" VLCC fully proves the effectiveness of airfoil rigid sails in ship energy conservation and emission reduction, marking a breakthrough in the popularization and application of ship sail resources in China. At present, in the engineering application research of sails, the number of airfoil sails has been increased from a pair of sails equipped on the "Kaili Wheel" to two pairs of sails equipped on the "New Yidun", and the sail blades have been upgraded from metal to non-metallic carbon fiber materials. Through actual ship tests, the application effect of the project's sail boosting is remarkable. How to improve the lightweight and intelligent operation of the sail device, and enhance the maintenance convenience and ship type applicability has become the key research direction for future sail-boosting device development.

[0074] The pitching rotating shaft 201 is a through shaft and is connected to both sides of the rotating driving equipment room 310; or it is two short shafts, which are respectively located on both sides of the base frame 401 and the rotating driving equipment room 310 and are symmetrically arranged; there is one stop arm 202 and one stop arm clamping projection 203 respectively, and the stop arm 202 is arranged at the bottom of the rotating driving equipment room 310; there is one driving equipment room clamping projection 311, which is arranged on the side wall of the driving equipment room 310;

[0075] The locking claw 206 includes a base clamping projection 404, a limit clamping projection, a locking claw, a claw driving mechanism, and a claw driving mechanism support.

[0076] Among them, the base clamping projection 404 is fixed above the base frame. Preferably, the base clamping projection 404 has a trapezoidal convex cross-section, and the convex platform faces horizontally towards the outside of the base. There are 2 base clamping projections 404, which are arranged symmetrically left and right along the Y direction, and a limit clamping projection is arranged in the middle of the base clamping projections 404;

[0077] The limit clamping projection refers to the clamping projection 311 between the driving devices or the clamping projection 203 of the stop arm. The clamping projection 311 between the driving devices and the clamping projection 203 of the stop arm are respectively fixed on the driving device room 310 between the rotary driving devices and the stop arm 202. When the sail is in the upright state, the clamping projection 311 between the driving devices acts as the limit clamping projection. At this time, the clamping projection 311 between the driving devices is arranged in the middle of the 2 base clamping projections 404, and the clamping projection 311 between the rotary driving devices is mechanically limited by the 2 base clamping projections 404 in the Y direction and cannot move; when the sail is in the tilted state, the clamping projection 203 of the stop arm acts as the limit clamping projection.

[0079] The locking claw 206 is arranged on the claw driving mechanism 205. The claw driving mechanism 205 realizes the horizontal movement of the locking claw 206 along the claw driving mechanism support 403, and realizes the mechanical meshing and disengagement of the locking claw 206 with the base clamping projection 404 and the limit clamping projection.

[0080] The claw driving mechanism support 403 is fixed on the upper part of the base frame 401 to realize the supporting effect on the claw driving mechanism 205.

[0081] When the locking claw 206 is in the released state, the limit clamping projection is in an unconstrained state. At this time, the locking claw 206 is driven by the claw driving mechanism 205 to approach one end of the claw driving mechanism support 403;

[0082] When the claw of the locking claw 206 is in the ready-to-position state, the limit clamping projection is driven by the folding mechanism 100 to move to the locking and positioning position. At this time, the limit clamping projection and the upper inclined surface 414, the convex vertical surface 424, and the lower inclined surface 444 of the convex of the base clamping projection 404 are respectively in a coincident state;

At this time, the limit clamping protrusion is in a fully constrained state in the X, Y and Z directions, and the limit clamping protrusion cannot move.

[0084] There is one locking claw 206, which is set at the top of the base frame 401 and corresponds to the position of the base protrusion 404; the claw driving mechanism 205 has a manual emergency operation function. When the power of the claw driving mechanism 205 fails, the locking claw 206 can be disengaged and locked through manual emergency operation.

[0085] There are two claw driving mechanisms 205.

[0088] The top of the base frame 401 is symmetrically provided with oil cylinder through holes 411 to prevent the oil cylinder piston rod 113 of the folding mechanism 100 from interfering with the base frame 401 during the extension and retraction process.

[0089] A pitch rotation shaft sleeve 211 is fixedly set on the top of the base frame 401. The pitch rotation shaft sleeve 211 cooperates with the pitch rotation shaft 201. The pitch rotation shaft sleeve 211 can be a shaft sleeve structure or a bearing structure.
