Description

Technical Field

[0001] This invention relates to the field of marine technology, specifically to a ship rotary sail device and method with anti-roll function. Background Technology

[0002] A ship's rotary sail is a wind-assisted propulsion device based on the Magnus effect. It uses an electric motor to drive a rotating drum. When wind blows perpendicularly to the drum from the side, the air pressure on the surface of the side rotating against the wind increases, while the air pressure on the surface of the side rotating with the wind decreases. This generates a force perpendicular to the airflow direction, which, when projected onto the ship's direction of travel, becomes the thrust propelling the ship forward. This principle is similar to the force that propels a football ball in an arc through the air. It offers advantages such as energy saving and emission reduction, wide adaptability to different ship types, low operating and maintenance costs, and convenient installation.

[0003] Chinese invention patent CN117885881A discloses a ship rotary sail device and its application method with anti-roll function. The device includes: a vent, a high-level vent valve, a mid-level water valve, a low-level water valve, a high-level water tank, a mid-level water tank, a low-level water tank, a bearing, a high-level liquid level sensor, a mid-level liquid level sensor, a low-level liquid level sensor, a drain pipe, a three-way valve, a water pump, a central shaft, a rotary sail, a water supply pipe, and a water inlet pipe. This invention addresses the issue of ship stability being affected during the application of rotary sails. By utilizing the hollow nature of the rotary sail, the overall mass of the rotary sail is increased, thereby increasing the moment of inertia of the rotary sail and improving the stability of the ship during navigation. Regarding the aforementioned technologies, the inventors believe that the following defects exist: the high-level water tank, the middle-level water tank, and the low-level water tank are set up, and water is supplied to the high-level water tank, the middle-level water tank, and the low-level water tank in sequence to increase the mass of the rotary sail. This results in the rotary sail having only three mass variations, and the difference between the three mass variations is large. Therefore, it is not possible to make more precise adjustments to the ship's rolling amplitude. Summary of the Invention

The circular toothed rack is controlled by the limiting mechanism to insert into the limiting hole to limit the water level control unit.

[0011] The upper part of the water storage tank is equipped with a laser rangefinder for monitoring the distance of the water level control frame. The laser rangefinder controls the height of the water level control frame so that the toothed rack and one of the limiting holes are coaxial.

[0012] Preferably, there are two sets of outer cylinder limiting plates and inner cylinder limiting plates, which are symmetrically distributed inside the water storage tank;

[0013] The outer cylinder limiting plate is fixedly connected to the outer cylinder, and the inner cylinder limiting plate is fixedly connected to the inner cylinder.

[0014] Preferably, the limiting mechanism includes a bidirectional telescopic rod fixed to the upper end of the water level control frame. Both ends of the bidirectional telescopic rod are provided with racks. The two racks are respectively meshed with two gears. The two gears are rotatably mounted on the upper end of the water level control frame via a rotating shaft.

[0015] A second fixing plate is provided on one side of the limiting hole, and the round rack is slidably connected to the second fixing plate, and the round rack is meshed with a second gear;

[0016] The upper end of the water level control frame is slidably connected to an arc-shaped guide post via a bracket. The two ends of the arc-shaped guide post are respectively provided with an arc-shaped rack one and an arc-shaped rack two. The arc-shaped rack one is meshed with a gear one, and the arc-shaped rack two is meshed with a gear two.

[0017] Preferably, the upper end of the water level control frame is provided with a fixing plate, and the fixing plate is located on the other side of the limiting hole. A pressure sensor is provided on one side of the fixing plate for detecting whether the circular rack is inserted into the limiting hole.

[0018] Preferably, the water level control frame includes an upper ring and a lower ring, which are fixedly connected by multiple connecting columns;

[0019] The upper and lower rings are symmetrically provided with two sets of sliders, and the sliders are slidably connected to the slide grooves.

[0020] Preferably, the sealing airbag includes two sets of notches, and the two sets of notches correspond to two sets of outer cylinder limiting plates and inner cylinder limiting plates;

[0022] Preferably, the bottom of the water level control frame is provided with a floating ring for improving the buoyancy of the water level control unit.

[0023] Preferably, the vortex cylinder has air holes near its upper end for stabilizing the air pressure inside the water storage tank.

[0024] Preferably, the central shaft is provided with multiple bearings on its exterior, the rotating cylinder is rotatably connected to the central shaft through the bearings, and the rotating cylinder is driven to rotate by a motor.

[0025] A method for using a ship's rotary sail with anti-roll function, in conjunction with a ship's rotary sail device with anti-roll function, includes the following steps:

[0026] S1. Water is supplied to the water storage tank through the water supply and drainage unit, which increases the mass of the rotating drum, increases the moment of inertia, and suppresses the swaying amplitude.

[0027] S2. After the water tank is filled with water, the water level control unit floats above the water level. The height of the water level control frame is monitored in real time by a laser rangefinder. When the water level control frame reaches the predetermined height, the water supply and drainage unit stops supplying water. The limit mechanism drives the rack to insert into the limit hole to fix the water level control frame. The pressure sensor can detect whether the rack is fully inserted into the limit hole.

[0028] S3. Inflate the sealing airbag with an air pump to make the sealing airbag bulge inside the water level control frame and seal the water level.

[0029] S4. The motor drives the rotating drum to increase the ship's thrust and reduce the sway amplitude.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] The present invention can supply water to the water storage tank through the water supply and drainage unit. After water is stored in the water storage tank, the mass of the rotating cylinder can be increased, thereby increasing the moment of inertia and suppressing the swaying amplitude.

[0032] When the water supply and drainage unit supplies water to the water storage tank, the floating ring makes the water supply and drainage unit float at the top of the water level. As the water level inside the water storage tank rises, the slider on the water level control frame slides upward in the groove. The laser rangefinder can monitor the height of the water level control frame in real time. When the water level control frame reaches the predetermined height, the water supply and drainage unit stops supplying water. The limit mechanism drives the rack to insert into the limit hole to fix the water level control frame. The rack is inserted into the limit hole at different heights, which represents different water storage volumes in the water storage tank. By setting several limit holes at different heights, the water storage volume in the water storage tank can be adjusted more precisely, thereby precisely adjusting the mass of the rotating drum. Therefore, the ship's rolling amplitude can be adjusted more precisely.

[0033] Once the water level control frame is fixed, the air pump inflates the sealing airbag, causing it to bulge inside the frame and seal the water level, thus keeping the water inside the storage tank in a relatively stable state. Attached Figure Description

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1-8 The present invention provides a technical solution: a ship rotary sail device with anti-roll function, including a base 1, a central shaft 11 is provided at the middle of the upper end of the base 1, a rotary cylinder 2 is rotatably installed on the outside of the central shaft 11, a plurality of bearings 10 are provided on the outside of the central shaft 11, the rotary cylinder 2 is rotatably connected to the central shaft 11 through the bearings 10, and the rotary cylinder 2 is driven to rotate by a motor.

[0045] The vortex 2 includes an inner cylinder 21 and an outer cylinder 22, and a water storage chamber 23 is formed between the inner cylinder 21 and the outer cylinder 22. The water storage chamber 23 is annular in shape. The bottom of the water storage chamber 23 is provided with a water supply and drainage unit 3 for storing and draining water. Near the upper end of the vortex 2, there is an air hole 28 for stabilizing the internal air pressure of the water storage chamber 23.

[0046] The water supply and drainage unit 3 can supply water to the water storage tank 23. After water is stored inside the water storage tank 23, the mass of the rotating cylinder 2 can be increased, thereby increasing the moment of inertia and suppressing the swaying amplitude. When the water supply and drainage unit 3 supplies water to the water storage tank 23, the air inside the water storage tank 23 can be discharged from the air hole 28, so that the air pressure inside and outside the water storage tank 23 is in a stable state.

[0047] The water storage tank 23 is equipped with a water level control unit for controlling the water level height, and the water level control unit floats inside the water storage tank 23 by the buoyancy of the water.

[0048] The water level control unit includes a water level control frame 4. The water storage tank 23 is provided with an outer cylinder limiting plate 24 and an inner cylinder limiting plate 25 for limiting the water level control frame 4. There are two sets of outer cylinder limiting plates 24 and inner cylinder limiting plates 25, which are symmetrically distributed inside the water storage tank 23. The outer cylinder limiting plate 24 is fixedly connected to the outer cylinder 22, and the inner cylinder limiting plate 25 is fixedly connected to the inner cylinder 21. A sliding groove 26 is provided between the outer cylinder limiting plate 24 and the inner cylinder limiting plate 25. The water level control frame 4 is connected to move up and down in the sliding groove 26. The inner cylinder limiting plate 25 has a number of limiting holes 27 evenly arranged in the upper and lower parts.

[0049] The water level control frame 4 includes an upper ring 43 and a lower ring 44, which are fixedly connected by multiple connecting columns 45. The upper ring 43 and the lower ring 44 are symmetrically provided with two sets of sliders 46, which are slidably connected to the slide groove 26.

[0050] The bottom of the water level control frame 4 is equipped with a floating ring 9 to improve the buoyancy of the water level control unit;

[0051] A circular rack 61 is movably provided on the upper end of the water level control frame 4, and the circular rack 61 is located on one side of the limiting hole 27. The circular rack 61 is inserted into the limiting hole 27 by the limiting mechanism 6 to limit the water level control unit.

[0052] The upper end of the water level control frame 4 is provided with a fixing plate 41, and the fixing plate 41 is located on the other side of the limiting hole 27. A pressure sensor 8 is provided on one side of the fixing plate 41 for detecting whether the circular rack 61 is inserted into the limiting hole 27.

[0053] The upper part of the water storage tank 23 is equipped with a laser rangefinder 7 for monitoring the distance of the water level control frame 4. The laser rangefinder 7 controls the height of the water level control frame 4 so that the circular rack 61 and one of the limiting holes 27 are in a coaxial state.

[0054] When the water supply and drainage unit 3 supplies water to the water storage tank 23, the floating ring 9 causes the water level control frame 4 to float at the upper end of the water level. As the water level inside the water storage tank 23 rises, the slider 46 on the water level control frame 4 slides upward in the groove 26. The laser rangefinder 7 can monitor the height of the water level control frame 4 in real time. When the water level control frame 4 reaches the predetermined height, the water supply and drainage unit 3 stops supplying water and drives the rack 61 to insert into the limiting hole 27 through the limiting mechanism 6 to fix the water level control frame 4. The rack 61 is inserted into the limiting hole 27 at different heights to represent water storage. Different water storage volumes within the storage tank 23 can be precisely adjusted by setting several limiting holes 27 of different heights, thereby precisely adjusting the mass of the rotating drum 2. This allows for more precise adjustment of the ship's sway amplitude. The pressure sensor 8 can detect whether the rack 61 is fully inserted into the limiting hole 27. When the rack 61 is fully inserted into the limiting hole 27, it will pass through the limiting hole 27 and squeeze the pressure sensor 8. Therefore, the system can indicate that the water level control frame 4 has been fixed, allowing the next step to proceed.

[0055] The limiting mechanism 6 includes a bidirectional telescopic rod 62 fixed to the upper end of the water level control frame 4. Both ends of the bidirectional telescopic rod 62 are provided with racks 63. The two racks 63 are respectively meshed with two gears 64. The two gears 64 are rotatably mounted on the upper end of the water level control frame 4 via a rotating shaft. A fixing plate 42 is provided on one side of the limiting hole 27. A circular rack 61 is slidably connected to the fixing plate 42, and the circular rack 61 is meshed with a gear 65. An arc-shaped guide post 66 is slidably connected to the upper end of the water level control frame 4 via a bracket. The two ends of the arc-shaped guide post 66 are respectively provided with an arc-shaped rack 67 and an arc-shaped rack 68. The arc-shaped rack 67 is meshed with the gear 64, and the arc-shaped rack 68 is meshed with the gear 65.

[0056] When the limiting mechanism 6 is working, the bidirectional telescopic rod 62 drives the straight racks 63 at both ends to move, causing the two gears 64 to rotate, causing the two arc racks 67 to move in an arc shape, causing the arc guide post 66 to slide on the bracket at the upper end of the water level control frame 4, causing the two arc racks 68 to drive the two gears 65 to rotate, causing the two round racks 61 to move and insert into the limiting hole 27, thereby fixing the water level control frame 4.

[0057] The water level control frame 4 is equipped with a sealing airbag 5 for sealing the water level. The sealing airbag 5 includes two sets of notches 51, and the two sets of notches 51 correspond to the two sets of outer cylinder limiting plates 24 and inner cylinder limiting plates 25.

[0058] The sealing airbag 5 is inflated by an air pump (not shown in the figure). When the water level control frame 4 is fixed, the air pump inflates the sealing airbag 5, causing the sealing airbag 5 to bulge inside the water level control frame 4, sealing the water level and keeping the water inside the water storage tank 23 in a relatively stable state.

[0059] A method for using a ship's rotary sail with anti-roll function, in conjunction with a ship's rotary sail device with anti-roll function, includes the following steps:

[0060] S1. Water is supplied to the water storage tank 23 through the water supply and drainage unit 3, which increases the mass of the rotating drum 2, increases the moment of inertia, and suppresses the swaying amplitude.

[0061] S2. After water enters the water storage tank 23, the water level control unit floats at the top of the water level. The height of the water level control frame 4 is monitored in real time by the laser rangefinder 7. When the water level control frame 4 reaches the predetermined height, the water supply and drainage unit 3 stops supplying water. The limit mechanism 6 drives the round rack 61 to insert into the limit hole 27 to fix the water level control frame 4. The pressure sensor 8 can detect whether the round rack 61 is fully inserted into the limit hole 27.

[0062] S3. Inflate the sealing airbag 5 with an air pump so that the sealing airbag 5 bulges inside the water level control frame 4 to seal the water level.

[0063] S4, the motor drives the rotating drum 2 to rotate, increasing the ship's thrust and reducing the sway amplitude.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
