[0002] Wind-assisted propulsion rotors are usually installed on the deck of a ship. They utilize the Magnus principle to obtain forward propulsion when the ship is in a crosswind or oblique wind state. The wind-assisted propulsion rotors in existing technology mainly include an outer cylinder and an inner cylinder. The inner cylinder is fixed to the deck of the ship through a base, and the outer cylinder is sleeved on the outer side of the inner cylinder. The outer cylinder rotates under the push of the oblique wind or crosswind, thereby enabling the ship to obtain forward propulsion.

[0003] However, during the rotation process, the outer cylinder has a large weight and rotational inertia. At the same time, there are fewer connection points between the outer cylinder and the inner cylinder. When the outer cylinder rotates at high speed, the outer cylinder itself will shake greatly, which will cause the outer cylinder to deform greatly, increasing the design cost and difficulty of the outer cylinder, and also affecting the life of the connection between the outer cylinder and the inner cylinder.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0018] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0019] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0020] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0021] In the prior art, only two sets of connection points are installed between the outer cylinder and the inner cylinder. Thus, when the outer cylinder rotates at high speed, the outer cylinder will shake, causing the contact points between the outer cylinder and the inner cylinder to deform.

[0022] In order to solve the above problems, Figures 1 to 2 As shown, the utility model provides a multi-support wind-assisted rotor, including a base 1, an inner cylinder 6 is fixed on the base 1, an outer cylinder 2 is sleeved on the inner cylinder 6, and a limiting wheel device 3 is installed on the side wall of the inner cylinder 6. The limiting wheel device 3 abuts against the inner wall of the outer cylinder 2. At the same axial height of the inner cylinder 6, the limiting wheel device 3 includes at least two groups. The limiting wheel devices 3 are installed at equal intervals around the circumference of the inner cylinder 6, and the limiting wheel devices 3 are installed at equal intervals on the inner cylinder 6 along the axial direction of the inner cylinder 6.

[0023] By installing multiple sets of limiting wheel devices 3 in the circumferential direction at the same height of the inner cylinder 6, the number of contacts between the limiting wheel devices 3 and the outer cylinder 2 is increased. During the rotation of the outer cylinder 2, the limiting wheel devices 3 can limit the shaking of the outer cylinder 2 in various directions and heights, reduce the amplitude of the shaking of the outer cylinder 2, reduce the stress value and deformation of the outer cylinder 2, and thus improve the service life of the outer cylinder 2; reduce the vibration of the multi-support wind-assisted rotor, and improve the operating stability of the multi-support wind-assisted rotor; reduce the design and manufacturing difficulty of the multi-support wind-assisted rotor, and greatly reduce the research and development and manufacturing costs of the outer cylinder 2. Since the shaking amplitude of the outer cylinder 2 is reduced, the number of impacts on the limiting wheel device 3 will also be reduced, thereby extending the service life of the roller in the limiting wheel device 3.

[0024] At the same axial height of the inner cylinder 6, the limiting wheel device 3 includes eight groups. By arranging 8 groups of limiting wheel devices 3 at the same height, it should be noted that an even number of limiting wheel devices 3 are installed at the same height of the inner cylinder 6. The number of limiting wheels can be 6 groups or ten groups, which needs to be installed according to the inner cylinder 6 of different diameters. Increasing the contact points between the limiting wheel device 3 and the outer cylinder 2 will increase the stability between the outer cylinder 2 and the inner cylinder 6 and reduce the amplitude of the outer cylinder 2 shaking. At the height of each layer of the limiting wheel device 3 installation, multiple groups of limiting wheel devices 3 are arranged to abut against the outer cylinder 2, so that the contact positions of the outer cylinder 2 and the limiting wheel device 3 are increased, the outer cylinder 2 is more restricted, and the amplitude of the outer cylinder 2 shaking is reduced.

[0025] A propulsion device is installed within the inner cylinder 6. The propulsion device propels the limiting wheel device 3 to move in a direction perpendicular to the axis of the inner cylinder 6. There is a one-to-one correspondence between the propulsion device and the limiting wheel device 3. The propulsion device can propel the limiting wheel device 3 to move radially, allowing the limiting wheel device 3 to adjust the pressing force between the limiting wheel device 3 and the outer cylinder 2. During the rotation of the outer cylinder 2, the pressing force between the limiting wheel device 3 and the outer cylinder 2 can be dynamically adjusted. When the outer cylinder 2 faces different crosswinds that can cause vibrations in different directions, the limiting wheel device 3 can compress the areas of the outer cylinder 2 with greater vibration, thereby reducing the vibration amplitude of the outer cylinder 2 and extending the service life of the multi-support wind-assisted propulsion rotor.

[0026] The utility model can use a linear cylinder as a power input source. The linear cylinder pushes the telescopic rod to move, and the end of the telescopic rod is rotatably installed with a limiting wheel device 3. When the telescopic rod in the linear cylinder is extended, the pressure between the limiting wheel device 3 and the outer tube 2 increases. Conversely, when the telescopic rod is retracted, the pressure is reduced, and it is flexibly adjusted through the telescopic cylinder.

[0027] A pressure sensor is installed on the limiting wheel device 3. The pressure sensor can detect the pressure between the limiting wheel device 3 and the outer tube 2. The pressure sensor is electrically connected to the controller, and the controller is electrically connected to the linear cylinder. When the pressure sensor detects that the vibration at a specific position of the outer tube 2 is large, the controller can control the telescopic cylinder to extend the telescopic rod to suppress the vibration in the above-mentioned area. The amplitude of the vibration of the outer tube 2 can be automatically controlled by the controller.

[0028] A bearing is installed on the top of the inner cylinder 6, and a rotating shaft 4 is installed on the inner ring of the bearing. The rotating shaft 4 is connected to the inner top of the outer cylinder 2. The entire outer cylinder 2 is supported by the rotating shaft 4 at the top of the inner cylinder 6, so that the outer cylinder 2 can rotate independently of the inner cylinder 6.

[0029] The rotating shaft 4 is connected to the outer cylinder 2 through a bracket. The crossbeam on the bracket is radial and connected to the outer cylinder 2. The rotating shaft 4 is installed at the center of the bracket, so that the stress in the area of ​​the outer cylinder 2 on the upper side of the rotating shaft 4 becomes smaller. At the same time, the radial bracket disperses the stress of the bracket and extends its service life.

[0030] A rolling groove 5 is provided on the inner wall of the outer cylinder 2, and the limiting wheel device 3 rolls in the rolling groove 5. The rolling groove 5 can limit the rolling area of ​​the limiting wheel device 3, thereby preventing the limiting wheel device 3 from shaking up and down along its own circumference, so that the outer cylinder 2 is more stable when rolling relative to the inner cylinder 6.

[0031] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
