[0041] One end of a screw rod 103 is connected to the rotor of the motor 102; the screw rod 103 is driven by the motor 102 to rotate;

[0042] The other end of the screw rod 103 is disposed on another side wall of the structural frame 101;

[0043] The screw rod 103 is provided with a nut 104 which matches with the screw rod;

[0044] A first movable support rod 105 is disposed on the nut 104; the nut 104 and the first movable support rod 105 are connected to the first movable support rod 105 via a first hinge 106;

[0045] A second movable support rod 116 is disposed on the first movable support rod 105; the first movable support rod 105 and the second movable support rod 116 are connected via a third hinge 107;

[0046] One end of the second movable support rod 116 is connected to the structural frame 101 via a fourth hinge 108;

[0047] The second movable support rod 116 is driven by the first movable support rod 105 to rotate around the fourth hinge 108 provided on the structural frame 101;

[0048] A movable support plate 110 is arranged on the second movable support rod 116, and the second movable support rod 116 is connected to the movable support plate 110 via a second hinge 109; the movable support plate 110 rotates along the second hinge 109 under the push of the second movable support rod 116, and the movable support plate 110 plays a supporting role during the process of the sail 1 being erected and tilted.

[0049] The winch mechanism 200 includes a winch 201 and a steel wire rope 202 connected to the winch 201 . The other end of the steel wire rope 202 is connected to the side wall of the sail 1 through a guide pulley 203 .

[0050] The winch 201 is arranged on the top of the common base 400 ; the guide pulley is arranged on the top of the support rod structure 204 , and the bottom of the support rod structure 204 is arranged on the top of the common base 400 .

[0051] A sail support 111 is disposed on the top of the structural frame 101 , and the sail support 111 supports the sail 1 when the lifting device 100 is in a tilted state, that is, when the sail 1 is in a tilted state.

[0052] When the sail 1 is in the tilted state, the movable support plate 110 is arranged horizontally, and its height is lower than the height of the sail body support 111 in the horizontal state.

[0053] One end of the pushing device 300 is fixedly arranged on the top of the common base 400, and the other end of the pushing device 300 is located at the bottom of the sail 1 in a vertical state.

The sail body support 111 is higher than the structural frame 101 and plays a role in vertically supporting the sail body 1.

[0057] When the sail 1 is tilted to stand upright, a large initial torque needs to be overcome in the initial state.

Figure 5 As shown, during this process, the movable support plate 110 is separated from the hull of the sail 1, and the hull of the sail 1 is completely erected by the winch mechanism 200.

[0059] When the sail 1 is in the process of being tilted from being upright, the winch 201 cooperates with the pushing device 300 to tilt the sail 1 in the initial state. When the sail 1 is in the range of 70°-80°, the lifting device 100 receives the sail 1. Figure 4 After that, the motor 102 rotates in reverse, and the lifting device 100 slowly tilts the sail 1 until it is completely tilted. During this process, the winch 201 simultaneously loosens the wire rope 202 to assist in tensioning.
