Description

Technical Field

[0001] The invention relates to the technical field of wind-assisted rotors, and in particular to a limiting wheel device for a wind-assisted rotor. Background Art

[0002] The working principle of the wind-assisted rotor is the Magnus effect. When a ship equipped with a wind-assisted rotor is in a crosswind or oblique wind state, adjusting the rotation direction of the rotor can make the ship generate thrust in the forward direction, thereby achieving a boosting effect. The wind-assisted rotor includes a base, an inner tower and an outer cylinder. The inner tower is fixed to the base, and the outer cylinder is rotatably sleeved on the outer side of the inner tower. The wind-assisted rotor is usually very tall, with a maximum diameter of 6 meters and a maximum height of nearly 40 meters. The outer cylinder rotates at high speed around the central axis of the inner tower. The rotation linear speed of the outer cylinder is very high, and the moment of inertia of the outer cylinder is very large, which puts a large impact load on the limiting wheel device. To reduce the vibration value and shaking amount of the outer cylinder and ensure the high-speed and stable operation of the outer cylinder, higher requirements are placed on the multiple limiting wheel devices evenly arranged at the bottom of the outer cylinder.

[0003] The roller in the existing limiting wheel device runs at high speed under the drive of the outer cylinder and bears the impact load from the outer cylinder. When the roller is slightly damaged, the rubber coating on the roller will quickly be damaged over a large area due to the performance factors of the material itself, and even the rubber coating will fall off.

[0034] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0035] like Figures 1 to 4 As shown, this embodiment provides a limiting wheel device for a wind-assisted rotor, the wind-assisted rotor comprises a base 1, an inner tower 2 and an outer cylinder 3, the inner tower 2 is fixedly arranged on the base 1, the outer cylinder 3 is rotatably sleeved on the outer side of the inner tower 2, the limiting wheel device comprises: a mounting member 4 and a roller assembly, the mounting member 4 is connected to the inner tower 2, and a receiving cavity is arranged inside the mounting member 4, the mounting member 4 has a first opening and a second opening communicating with the receiving cavity, the first opening is closer to the outer cylinder 3 than the second opening, the roller assembly comprises a plurality of rollers 5, the plurality of rollers 5 are mounted on the mounting member 4 and placed in the receiving cavity, the plurality of rollers 5 partially extend out of the first opening, and each roller 5 is in rolling contact with the outer cylinder 3. With such a configuration, when the roller 5 in the limiting wheel device is damaged and needs to be replaced, the maintenance personnel can directly remove and replace the damaged roller 5 through the second opening without disassembling the mounting member 4, which effectively improves the replacement efficiency of the roller 5 in the limiting wheel device and reduces the workload of the maintenance personnel.

[0036] Optionally, the roller assembly further includes a main shaft 6, and a plurality of rollers 5 are rotatably connected to the main shaft 6, and any two adjacent rollers 5 are spaced apart, and both ends of the main shaft 6 are respectively mounted on the mounting member 4. In this arrangement, the main shaft 6 effectively supports the plurality of rollers 5 to ensure the stability of their rotation, and at the same time, a gap is left between any adjacent rollers 5, which effectively increases the heat dissipation area between the rollers 5, so that the heat generated by the interaction between the rollers 5 and the outer cylinder 3 can be dissipated more fully and quickly, further extending the service life of the rubber coating material of the rollers 5.

[0037] In this embodiment, please refer to Figure 5 and Figure 6As shown, in order to further effectively enhance the heat dissipation effect of the roller 5, a plurality of cooling slots 51 penetrating the roller 5 are provided on the end surface of the roller 5. The cooling slots 51 are arranged along the circumferential direction, and the extension direction of the cooling slots 51 is the same as the axial direction of the main shaft 6; or, the extension direction of the cooling slots 51 is arranged at an angle to the axial direction of the main shaft 6. With such an arrangement, when the roller 5 rotates at a high speed, the cooling slots 51 can push the surrounding gas to flow along the axial direction of the roller 5 itself, thereby more fully dissipating the heat of the roller 5 itself.

[0038] Optionally, in order to support the rotation of the roller 5, reduce the friction coefficient during its movement, and ensure the rotation accuracy, the roller assembly also includes a plurality of bearings, and the plurality of bearings are arranged one-to-one corresponding to the plurality of rollers 5, and the inner ring of the bearing is fixedly connected to the main shaft 6, and the outer ring of the bearing is fixedly connected to the roller 5.

[0039] In this embodiment, the roller 5 adopts a double-wheel or multi-wheel structure. During the actual operation, even if a roller 5 is damaged, it is only necessary to replace the damaged roller 5, and it is not necessary to replace all of them, which greatly saves the production cost. At the same time, when a roller 5 in the limiting wheel device is damaged, the other rollers 5 can continue to support the rotation of the outer cylinder 3, which has little effect on the high-speed operation of the outer cylinder 3, thereby ensuring the stability and safety of the outer cylinder 3 when running at high speed.

[0040] Optionally, the limiting wheel device also includes a first slide rail and a first slider 7, the first slider 7 is connected to one end of the main shaft 6, the first slide rail is protruding on the outer wall of the mounting member 4, and the first slide rail is extended along the first direction, and the first slider 7 is slidably set on the first slide rail. Further, the limiting wheel device also includes a second slide rail and a second slider 8, the second slider 8 is connected to the other end of the main shaft 6, the first slide rail and the second slide rail are opposite to and spaced apart on the two outer walls of the mounting member 4 along the second direction, the second slide rail is extended along the first direction, the second slider 8 is slidably set on the second slide rail, and the first direction is perpendicular to the second direction. With such a configuration, the first slider 7 and the second slider 8 can drive the main shaft 6 to move along the first direction, so that when the roller 5 is subjected to a strong impact load of the outer cylinder 3, a certain buffer space is provided for the roller 5. It should be noted that the first direction and the second direction are respectively as follows: Figure 3 The two arrows in the diagram indicate the direction.

[0041] Specifically, the following scheme is exemplarily given in this embodiment: the first slide rail includes two first rails 11, the second slide rail includes two second rails 12, a first slot 13 and a second slot 14 are opened on the mounting member 4, the first slot 13 and the second slot 14 are both connected to the second opening, the first slot 13 is located between the two first rails 11, the second slot 14 is located between the two second rails 12, and both ends of the main shaft 6 extend out of the first slot 13 and the second slot 14 respectively.

[0042] Optionally, in order to limit the first slider 7 and the second slider 8 in the first direction, the limiting wheel device also includes a cover plate 9, which is connected to the mounting member 4 and is used to close the second opening. The first slider 7 and the second slider 8 can both abut against the cover plate 9 along the first direction.

[0043] Furthermore, the limiting wheel device further includes a first buffer pad 10 and a second buffer pad, wherein the first buffer pad 10 is arranged between the first slider 7 and the cover plate 9, and the second buffer pad is arranged between the second slider 8 and the cover plate 9. With such arrangement, when the roller 5 is subjected to the impact load of the outer cylinder 3, the roller 5 can slide along the first direction, and the first buffer pad 10 and the second buffer pad further play a buffering and shock absorbing role, buffering and absorbing the load generated by the outer cylinder 3 when running at high speed, and ensuring that the outer cylinder 3 can continue to run smoothly at high speed.

[0044] Furthermore, the limiting wheel device further includes a plurality of bolts, all of which penetrate the cover plate 9 and are threadedly connected to the mounting member 4. In this configuration, the cover plate 9 is connected to the mounting member 4 by bolts, and the cover plate 9 is in contact with the first buffer pad 10 and the second buffer pad at the same time. The tightness of the bolts can be adjusted to adjust the pressing degree of the roller 5 on the outer cylinder 3, ensuring that each roller 5 is pressed against the outer cylinder 3, which is conducive to ensuring the running stability of the outer cylinder 3 and improving the service life of the roller 5.

[0045] It should be noted that when the roller 5 needs to be replaced, it is only necessary to remove the cover plate 9 first, and the roller assembly, the first slider 7 and the second slider 8, the first buffer pad 10 and the second buffer pad can be directly removed from the second opening of the mounting member 4 without removing the mounting member 4. This is convenient and quick, greatly reducing the workload of disassembling and assembling the roller 5 and improving work efficiency.

[0046] Optionally, an outer side wall of the mounting member 4 is provided with a mounting ear protruding therefrom, and the mounting ear is used to be connected to the inner tower 2 .

[0047] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods 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.
