Description

Technical Field

[0002] In recent years, the requirements for the green level of ships have been increasing, and countries around the world have actively developed various energy-saving and emission-reduction technologies.

The hard wing sail product adopts a mast and sail blade structure. By setting up a lifting system and a slewing system, the automatic lifting and angle adjustment of the sail blade can be realized, thereby effectively utilizing wind resources. During the lifting process of the hard wing sail, the mast and sail blade must be upright, which makes it difficult to maintain the sail, causing a series of problems such as limited driving vision and poor ship type applicability for ship layout and navigation.

Since the tiltable sail body adopts non-metallic fiber material, the weight of the sail body is greatly reduced, and the weight of a single sail body is about within 20 tons. Although the weight of the sail body is greatly reduced, due to the high height of the tiltable sail body, the 30m high hard wing-shaped sail blade, depending on the width of the sail blade and the selection of the sail blade material, its maximum weight can reach nearly 100 tons. During the tilting process, the gravity resistance torque that needs to be overcome by the sail blade of this weight is as high as 15000kNm. This resistance torque needs to be overcome by the driving mechanism to generate sufficient power torque, and it needs to be arranged in the limited deck space of the ship, and adapt to the periodic roll, pitch, heave load of the ship and the sudden impact of wind power load, which has high requirements for the tiltable sail device, and the prior art tiltable sail device cannot meet the above requirements.

[0033] Preferred embodiment 1

[0034] A tiltable sail device capable of overcoming large overturning resistance is characterized by comprising: a sail blade 1;

[0035] A slewing bearing 3 driving the sail blade to rotate in the vertical direction;

[0036] A slewing bearing upper seat 2 connecting the sail blade 1 and the slewing bearing 3;

[0037] A sail base 10 disposed on the deck for supporting the sail blade 1;

[0038] A slewing support lower seat 4 connecting the slewing support 3 and the sail base 10;

[0039] A driving mechanism 100 for driving the sail blade 1 to pitch;

[0040] The driving mechanism 100 is arranged between the sail base 10 and the deck, and is a mechanism that can simultaneously withstand the alternating loads of tension and pressure of the sail blade 1 during the pitching process; the driving mechanism 100 is a two-section hinge structure, one end of the driving mechanism 100 is hinged to the deck; the other end of the driving mechanism 100 is hinged to the sail base 10.

[0041] The sail base 10 is hingedly connected to the slewing support lower seat 4 via a pitch hinge shaft 9 .

[0042] The driving mechanism 100 includes a driving device 101 for driving the sail blade 1 to pitch; and a moment arm 5 fixedly connected to the slewing bearing lower seat 4 and hingedly connected to the sail base 10 through a pitch hinge shaft 9; one end of the driving device 101 is hingedly connected to the moment arm 5; and the other end of the driving device 101 is connected to the deck.

[0043] The driving device 101 is connected to the deck via a driving device base 102 . The driving device 101 is hinged to the moment arm 5 , and the driving device base 102 is fixedly connected to the deck.

[0044] The driving device base 102 is arranged on the side of the tilting direction of the sail blade 1. Figure 4 and Figure 5 As shown, when the sail blade 1 is in the tilted state, the piston rod 602 is in the fully extended state. When the sail blade 1 is in the upright operation, the piston rod 602 is retracted to provide a huge pulling force, and the piston rod hinge shaft 11 drives the moment arm 5 to rotate clockwise around the pitch hinge shaft 9, thereby driving the sail blade 1 to rotate clockwise until the sail blade 1 is in the upright state, and the piston rod 602 is fully retracted. During this rotation process, the piston rod 602 may be subjected to tension or pressure.

[0045] The driving device 101 is a double-acting oil cylinder 6 ; the driving device base 102 is an oil cylinder base 8 .

The wind energy of the relative wind speed of the ship is converted into the forward thrust of the ship through the structure of the sail blade 1 itself.

[0048] The slewing bearing upper seat 2 is a transitional steel structure connecting the sail blade 1 and the slewing bearing 3 .

The setting of the moment arm 5 can greatly reduce the driving force load of the driving mechanism 100 .

[0054] A slewing bearing 3 driving the sail blade to rotate in the vertical direction;

[0055] A slewing bearing upper seat 2 connecting the sail blade 1 and the slewing bearing 3;

[0056] A sail base 10 disposed on the deck for supporting the sail blade 1;

[0057] A slewing support lower seat 4 connecting the slewing support 3 and the sail base 10;

[0058] A driving mechanism 100 for driving the sail blade 1 to pitch;

[0059] The driving mechanism 100 is arranged between the sail base 10 and the deck, and is a mechanism that can simultaneously withstand the alternating loads of tension and pressure of the sail blade 1 during the pitching process; the driving mechanism 100 is a two-section hinge structure, one end of the driving mechanism 100 is hinged to the deck; the other end of the driving mechanism 100 is hinged to the sail base 10.

[0060] The sail base 10 is hingedly connected to the slewing support lower seat 4 via a pitch hinge shaft 9 .

[0061] The driving mechanism 100 includes a driving device 101 for driving the sail blade 1 to pitch; and a moment arm 5 fixedly connected to the slewing bearing lower seat 4 and hingedly connected to the sail base 10 through a pitch hinge shaft 9; one end of the driving device 101 is hingedly connected to the moment arm 5; and the other end of the driving device 101 is connected to the deck.

[0062] The driving device 101 is connected to the deck via a driving device base 102 . The driving device 101 is hinged to the moment arm 5 , and the driving device base 102 is fixedly connected to the deck.

[0063] The driving device base 102 is arranged on the opposite side of the tilting direction of the sail blade 1. Figure 6 and Figure 7As shown, when the sail blade 1 is in the dumped state, the piston rod 602 is in the fully retracted state. When the sail blade 1 is in the upright operation, the piston rod 602 is extended to provide a huge pushing force, and the piston rod hinge shaft 11 drives the moment arm 5 to rotate clockwise around the pitch hinge shaft 9, thereby driving the sail blade 1 to rotate clockwise until the sail blade 1 is in the upright state, and the oil cylinder piston rod 602 is fully extended. In this process, the piston rod 602 may be subjected to pressure or tension.

[0064] The driving device 101 is a double-acting oil cylinder 6 ; the driving device base 102 is an oil cylinder base 8 .

[0065] The double-acting cylinder 6 includes a cylinder barrel 601, and a piston rod 602 is arranged in the cylinder barrel 601; the bottom hinge of the cylinder barrel 601 is provided with a cylinder base 7; the cylinder base 7 is fixedly connected to the cylinder base 8; the cylinder base 7 is hinged to the double-acting cylinder 6 through a cylinder barrel hinge shaft 12; the piston rod 602 is hinged to the moment arm 5 through a piston rod hinge shaft 11.

[0066] During the pitching process of the sail blade 1 switching from the upright state to the tilted state, the sail blade 1 is subjected to the superposition of three loads: wind force load, inertial acceleration load in the XOZ plane of the ship, and sail blade gravity load. Among them, affected by the change of wind direction and the change of the attitude of the sail blade 1, the wind force component of the sail blade 1 in the X and Z directions may have two sudden changes in the direction, that is, the longitudinal component of the wind force on the sail blade 1 may be F x1 , or possibly F x2 Due to the periodic pitching and heaving of the ship, the longitudinal acceleration and vertical acceleration of the sail blade 1 may change suddenly in two directions, that is, the vertical acceleration of the sail blade 1 may be a z1 , or it may be a z2 , the longitudinal acceleration of sail blade 1 may be a x1 , or it may be a x2 Therefore, during the pitching process of the sail blade 1, the load on the sail blade 1 is extremely complex, with a combination of multiple working conditions, and there is an instantaneous mutation superposition effect under the influence of the external environment. The present invention adopts a double-acting oil cylinder 6, and the oil cylinder piston rod 602 can simultaneously withstand the alternating loads of tension and pressure, ensuring that the operating speed of the sail blade 1 drive mechanism 100 is reasonable and reducing the impact of the external load on the drive mechanism 100. The double-acting oil cylinder 6 has the advantage of stepless speed change, which can adjust the angular velocity of the pitch of the sail blade 1, and can make full use of the push and pull force of the double-acting oil cylinder 6 to optimize the energy consumption of the device.
