Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, and in particular to a multi-support wind-assisted propulsion rotor. Background Art

[0002] Wind-assisted rotors are usually installed on the deck of a ship. The wind-assisted rotors utilize the Magnus principle to obtain forward momentum when the ship is in a crosswind or oblique wind state. The wind-assisted rotors in the prior art 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 side of the inner cylinder is sleeved with the outer cylinder. The outer cylinder rotates under the push of oblique wind or crosswind, thereby enabling the ship to obtain forward momentum.

[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 a 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 will also affect the life of the connection between the outer cylinder and the inner cylinder. Summary of the invention

[0004] The purpose of the present invention is to provide a multi-support wind-assisted rotor to solve the problem of shaking and deformation of the lower outer cylinder during rotation in the prior art.

[0012] Preferably, a rolling groove is formed on the inner wall of the outer cylinder, and the limiting wheel device rolls in the rolling groove.

[0013] Beneficial effects: By adding limiting wheel devices in the circumferential and axial directions of the inner cylinder, the contact points between the inner cylinder and the outer cylinder are increased, and limiting wheel devices are set in the circumferential direction of the outer cylinder for limiting, the stress and deformation of the outer cylinder are limited.

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0018] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

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

[0020] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description 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 a high speed, the outer cylinder will shake, causing the contact point between the outer cylinder and the inner cylinder to deform.

[0022] In order to solve the above problems, Figure 1 to Figure 2 As shown, the present invention 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, a limiting wheel device 3 is installed on the side wall of the inner cylinder 6, the limiting wheel device 3 is in contact with the inner wall of the outer cylinder 2, and 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 shaking amplitude of the outer cylinder 2, reduce the stress value and deformation of the outer cylinder 2, and thus increase 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 particularly 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 need 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, thereby improving the stability between the outer cylinder 2 and the inner cylinder 6 and reducing the amplitude of the outer cylinder 2 shaking. At the installation height of each layer of the limiting wheel device 3, 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 in the inner cylinder 6, and the propulsion device pushes the limiting wheel device 3 to move in a direction perpendicular to the axis of the inner cylinder 6, and the propulsion device corresponds to the limiting wheel device 3 one by one. The propulsion device can push the limiting wheel device 3 to move radially, so that the limiting wheel device 3 adjusts 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, so that when the outer cylinder 2 faces different directions of crosswinds that can cause vibrations in different directions, the limiting wheel device 3 can be used to press the area of ​​the outer cylinder 2 with larger vibrations, thereby reducing the vibration amplitude of the outer cylinder 2 and extending the service life of the multi-support wind-assisted rotor.

[0026] The present invention can use a linear cylinder as a power input source. The linear cylinder pushes the telescopic rod to move, and a limiting wheel device 3 is rotatably installed at the end of the telescopic rod. 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 the telescopic cylinder is flexibly adjusted.

[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 stress of the bracket is dispersed through the radial bracket to extend the 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 to prevent 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 embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
