Description

Technical Field

[0001] The invention belongs to the field of tiltable sails and relates to a tiltable sail device with compact structure and low power consumption. Background Art

[0002] With the increasing requirements for the green level of ships, countries around the world 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 propulsion, as the oldest energy-saving technology, has returned to the stage of green application in shipping. How to improve the lightweight and intelligent operation of the sail device, improve the convenience of maintenance and the applicability of the ship type, has become the key direction of the research and development of the sail propulsion device in the future. 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, and causes a series of problems such as limited driving vision and poor ship applicability for ship layout and navigation.

[0003] The prior art tiltable sail device can tighten and release the wire rope through the wire rope winch set on the common base of the sail to achieve the upright and tilting operation of the sail body. 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 less than 20 tons. Although the weight of the sail body is greatly reduced, due to the high height of the tiltable sail body, usually around 30m, during the tilting or upright operation, the gravity alone will produce a large overturning resistance torque, which needs to be overcome by the driving mechanism to generate sufficient power torque, and the power consumption demand of the driving mechanism is very large. The transmission layout space structure is complex and occupies a large space, which is not conducive to the deck layout of the sail device. The transmission accuracy and efficiency are low, the failure rate is high, the operation reliability is low, the manufacturing cost and maintenance cost are high, and the service life is short. Summary of the invention

[0004] The present invention aims to solve the problems that the existing tiltable sail device has a high power consumption requirement for the driving mechanism when the sail body is pulled up from the tilted state by the steel wire rope. The transmission layout space structure is complex and occupies a large space, which is not conducive to the deck layout of the sail device, and the transmission accuracy and efficiency are low, the failure rate is high, the operation reliability is low, and the manufacturing cost and maintenance cost are high. A tiltable sail device with a compact structure and low power consumption is provided, which is characterized by: comprising a gear drive mechanism, and a pitch mechanism coupled with the gear drive mechanism,

[0005] The gear drive mechanism is a speed reduction mechanism, and the driving torque and driving speed of the gear drive mechanism are adjustable.

[0006] According to the above-mentioned compact and low-power tiltable sail device, it is characterized in that the gear drive mechanism is an open gear mechanism.

[0017] The pitch mechanism comprises: a pitch hinge axis;

[0018] The pitch hinge shaft is connected to the sail blade, and the pitch hinge shaft drives the sail blade to tilt and stand upright during the rotation process;

[0019] The pitch hinge shaft and the sail blade are connected through a slewing mechanism.

[0020] The compact and low-power tiltable sail device described above is characterized in that the motor, brake, reducer, bearing seat and pinion are all fixedly arranged on the driving base.

[0021] According to the above-mentioned compact and low-power tiltable sail device, it is characterized in that the pitch hinge axis is rotatably arranged on the base of the sail.

[0022] According to the above-mentioned compact and low-power tiltable sail device, it is characterized in that the rotation axis of the large gear is coaxial with the rotation axis of the pitch hinge axis.

[0023] According to the above-mentioned compact and low-power tiltable sail device, it is characterized in that the large gear is a fan-shaped structure, and the gear teeth of the gear are distributed on the circular arc of the fan-shaped structure.

[0024] According to the above-mentioned compact and low-power tiltable sail device, it is characterized in that the central angle of the fan-shaped structure of the large gear is 90°-145°.

[0025] According to the above-mentioned compact and low-power tiltable sail device, it is characterized in that the gear drive mechanism and the pitch mechanism are symmetrical structures arranged on both sides of the base.

[0026] According to the above-mentioned compact and low-power tiltable sail device, it is characterized in that the motor is a variable frequency speed regulating motor.

[0027] The advantages of the present invention compared with the prior art are:

[0028] 1. The present invention adopts a gear drive mechanism, which reduces the requirements for motor output torque and motor power through gear speed reduction, that is, it plays a role in reducing energy consumption. At the same time, the gear transmission structure is compact, which is conducive to the deck layout of the sail device, and the gear transmission has high accuracy and efficiency, low failure rate, reliable operation, low manufacturing cost and maintenance cost, and long service life.

[0029] 2. The tiltable sail device arranged on the deck of the ship includes a large gear, a small gear, a motor, a reducer, etc. The torque is amplified by the reducer, and the transmission ratio is increased by the small gear and the large gear at the reducer end, so as to amplify the output torque again and improve the carrying capacity of the device.

[0030] 3. The present invention can adjust the pitch angular velocity of the sail blade by frequency conversion speed regulation of the motor. When the external load borne by the sail blade is relatively small relative to the rated torque of the motor, the pitching speed of the sail blade can be increased by frequency conversion speed regulation, and vice versa, the pitching speed of the sail blade can be reduced. By adopting this scheme, while fully utilizing the output torque of the motor, it can also ensure that the operating speed of the sail pitch mechanism is reasonable and reduce the impact of the external load on the pitch drive. The transmission accuracy is high, and the pitch angle of the sail blade can be accurately positioned. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] Preferred Embodiments

[0037] The compact and low-power tiltable sail device comprises a gear drive mechanism 100 and a pitch mechanism 200 coupled to the gear drive mechanism 100.

[0038] The gear drive mechanism 100 is a speed reduction mechanism, and the driving torque and driving speed of the gear drive mechanism 100 are adjustable.

[0039] The gear drive mechanism 100 is an open gear mechanism.

[0040] The gear drive mechanism 100 comprises: a motor 1; a reducer 4 connected to the motor 1;

[0041] A high-speed end coupling 2 is connected between the motor 1 and the input end of the reducer 4;

[0042] A brake 3 is provided on the high-speed end coupling 2 to brake the reducer 4;

[0043] A pinion 10 connected to the output end of the reducer 4;

[0044] A low-speed end coupling 5 is provided between the output end of the reducer 4 and the pinion 10;

[0045] Bearing seats 6 are provided on both sides of the pinion 10 to support the pinion 10;

[0046] A large gear 7 meshing with a small gear 10;

[0047] The pitch mechanism 200 comprises: a pitch hinge shaft 13;

[0048] The pitch hinge shaft 13 is connected to the sail blade 8, and the pitch hinge shaft 13 drives the sail blade 8 to tilt and stand upright during the rotation process;

[0049] The pitch hinge shaft 13 is connected to the sail blade 8 via a slewing mechanism 9 .

[0050] The motor 1 , the brake 3 , the reducer 4 , the bearing seat 6 , and the pinion 10 are all fixedly arranged on the driving base 11 .

[0051] The pitch hinge shaft 13 is rotatably arranged on the base 12 of the sail.

[0052] The rotation axis of the large gear 7 is coaxial with the rotation axis of the pitch hinge axis 13 .

[0053] The large gear 7 is a sector-shaped structure, and the gear teeth thereof are distributed on the circular arc of the sector-shaped structure.

[0054] The central angle of the sector-shaped structure of the large gear 7 is 90°-145°.

[0055] The gear driving mechanism 100 and the pitch mechanism 200 are symmetrical structures disposed on both sides of the base 12 .

[0056] The motor 1 is a variable frequency speed regulating motor.

[0057] like Figure 2 As shown in the figure, when the tiltable sail device is in the tilting and recovery state, the small gear 7 is meshed with the large gear 10 on the right side of the large gear 7. When the motor 1 drives the small gear 10 to rotate clockwise, the small gear 10 drives the large gear 7 to rotate counterclockwise. Since the large gear 7 and the pitch hinge shaft 13 at the root of the sail blade 8 are relatively stationary, the sail blade 8 is driven to complete the upright operation through the clockwise positive rotation of the motor 1. The upright state is shown in Figure 1. At this time, the small gear 10 is meshed with the large gear 7 on the left side of the large gear 7. The sail blade 8 is controlled to complete the pitching action by controlling the motor 1 to rotate forward and reverse.

[0058] The pitching angular velocity of the sail blade 8 can be adjusted by the variable frequency speed regulation of the motor 1. When the external load borne by the sail blade 8 is relatively small relative to the rated torque of the motor 1, the pitching speed of the sail blade 8 can be increased by the variable frequency speed regulation, and vice versa, the pitching speed of the sail blade 8 can be reduced. This solution can not only fully utilize the output torque of the motor, but also ensure that the operating speed of the sail pitching mechanism is reasonable and reduce the impact of the external load on the pitching drive.

[0059] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any person familiar with the technical field can make equivalent replacements or changes according to the technical solution and inventive concept of the present invention within the technical scope disclosed by the present invention, which are all covered by the protection scope of the present invention. For example: placing the slewing mechanism 9 below the pitch hinge shaft 13; replacing the variable frequency motor of the motor 1 with other types of motors; changing the motor series reducer to a reduction motor or a hydraulic motor; integrating the reducer 4 with the large gear 7, that is, a set of large speed ratio reducers or several reducers in series, such as a gearbox reducer in series with a planetary reducer.
