Description

Technical Field

[0001] This invention relates to the field of wind-powered propulsion rotor technology, and more particularly to a limiting device and a wind-powered propulsion system for wind-powered propulsion rotors. Background Technology

[0002] The working principle of the wind-powered propulsion rotor is the Magnus effect. When a ship equipped with a wind-powered propulsion rotor is in crosswind or diagonal wind conditions, adjusting the rotation direction of the rotor can generate thrust in the forward direction of the ship, thereby achieving a propulsion effect.

[0003] A wind-powered propulsion rotor generally includes a base, an inner tower, and an outer cylinder. The inner tower is fixed to the base, and the outer cylinder is rotatably fitted onto the outside of the inner tower. Due to manufacturing processes and the operating environment, there may be a misalignment between the coaxiality of the outer cylinder axis and the inner tower axis. To limit the radial runout of the outer cylinder, multiple limiting wheel devices are generally installed along the circumference of the outer cylinder. The limiting wheel devices include limiting wheels that abut against the cylinder wall of the outer cylinder to restrict the radial runout of the outer cylinder.

[0004] Wind-powered rotors are typically very tall, with a maximum diameter of six meters and a maximum height of nearly forty meters. The outer cylinder needs to rotate at high speed around the central axis of the inner tower. The outer cylinder has a high rotational linear velocity and a very large moment of inertia. To ensure the smooth and high-speed operation of the outer cylinder and reduce its sway, high requirements are placed on the limiting wheel device at the bottom of the outer cylinder.

[0005] In existing limit wheel devices, the axles of the limit wheels are slidably mounted on the base. This results in low contact stability between the limit wheels and the outer cylinder, leading to drawbacks such as high assembly workload and difficulty in controlling installation accuracy. If the assembly error of each limit wheel device is too large, the rotor outer cylinder will experience severe shaking during high-speed operation, increasing the roller load and directly affecting its service life. Furthermore, it cannot guarantee continuous and stable rotor operation, causing the outer cylinder speed to fall below design requirements. Additionally, significant internal stress and torsional deformation may occur locally within the outer cylinder, potentially leading to rotor safety accidents. Summary of the Invention

[0006] The purpose of this invention is to provide a limiting device and a wind-powered boosting system for a wind-powered rotor. The device has a simple structure, is easy to assemble and adjust, and improves the stability of the contact between the limiting roller and the outer cylinder, thereby ensuring the smoothness of the outer cylinder during high-speed operation.

[0043] like Figure 1-6As shown, this embodiment provides a limiting device for a wind-powered booster rotor. The wind-powered booster rotor includes a base 100, an inner tower 200, and an outer cylinder 300. The inner tower 200 is fixed to the base 100, and the outer cylinder 300 is rotatably sleeved on the outside of the inner tower 200. The limiting device for the wind-powered booster rotor includes a plurality of limiting units 1 distributed along the outer or inner circumference of the outer cylinder 300. Each limiting unit 1 includes a roller mechanism 11, an adjusting mechanism 12, and an elastic element 13. The roller mechanism 11 includes a limiting roller 111 and a mounting bracket 112. The mounting bracket 112 has a limiting roller 111 along the first... The first end 1121 and the second end 1122 are distributed in opposite directions. The first end 1121 is rotatably disposed on the base 100 or the inner tower 200. The limiting roller 111 is rotatably disposed on the second end 1122. The outer peripheral surface of the limiting roller 111 abuts against the outer wall or inner wall of the outer cylinder 300. The adjustment mechanism 12 includes an adjustment component 121. One end of the adjustment component 121 abuts against the second end 1122. The adjustment component 121 is used to adjust the force between the limiting roller 111 and the outer cylinder 300. The elastic element 13 is clamped between the adjustment component 121 and the second end 1122.

[0044] The outer circumferential surface of the limiting roller 111 abuts against the outer or inner wall of the outer cylinder 300. The force between the limiting roller 111 and the outer cylinder 300 can be adjusted by the adjusting component 121 to ensure that the force between each limiting roller 111 and the outer cylinder 300 is basically consistent. The elastic element 13 allows the limiting roller 111 to have a certain range of displacement, absorbing and buffering the load generated by the outer cylinder 300 during high-speed operation, ensuring the stability of the outer cylinder 300 during high-speed operation, and helping to extend the service life of the limiting roller 111. At the same time, the first end 1121 of the mounting bracket 112 is rotatably mounted on the base 100 or the inner tower 200, and the limiting roller 111 is rotatably mounted on the second end 1122 of the mounting bracket 112. Compared with the prior art, this not only facilitates the installation and disassembly of the limiting roller 111, but also facilitates the adjustment of the clamping force of the limiting roller 111, improving the contact stability between the limiting roller 111 and the outer cylinder 300.

[0045] It should be noted that the distribution of the limiting units 1 on the outer or inner circumference of the outer cylinder 300 can be determined according to the diameter of the outer cylinder 300. Specifically, in order to facilitate the installation of the limiting units 1 and ensure the contact stability between the limiting roller 111 and the outer cylinder 300, when the diameter of the outer cylinder 300 is small, multiple limiting units 1 are installed on the base 100. In other words, multiple limiting units 1 are distributed along the outer circumference of the outer cylinder 300. Specifically, the first end 1121 of the mounting bracket 112 is rotatably provided on the base 100, and the outer circumferential surface of the limiting roller 111 abuts against the outer wall of the outer cylinder 300. When the diameter of the outer cylinder 300 is large, multiple limiting units 1 are installed on the inner tower 200. In other words, multiple limiting units 1 are distributed along the inner circumference of the outer cylinder 300. Specifically, the first end 1121 of the mounting bracket 112 is rotatably provided on the inner tower 200, and the outer circumferential surface of the limiting roller 111 abuts against the inner wall of the outer cylinder 300.

[0046] Optionally, the first end 1121 of the mounting bracket 112 is provided with a rotating shaft 1123. One end of the rotating shaft 1123 is fixedly connected to the first end 1121, and the other end is rotatably connected to the base 100 or the inner tower 200. For example, the other end of the rotating shaft 1123 can be rotatably connected to the base 100 or the inner tower 200 through a rotating support such as a bearing, so as to improve the smoothness of the rotation of the mounting bracket 112. This configuration realizes the rotatable connection between the mounting bracket 112 and the base 100, and when adjusting the clamping force between the limiting roller 111 and the outer cylinder 300, the limiting roller 111 can move radially flexibly, which is beneficial for accurately adjusting the clamping force of the limiting roller 111 on the outer cylinder 300 and improving the stability of the contact between the limiting roller 111 and the outer cylinder 300.

[0047] Optionally, the adjustment mechanism 12 also includes a pressure detection element 122, such as a force sensor, which is used to detect the pressure between the adjustment component 121 and the second end 1122. This allows the pressure between the adjustment component 121 and the second end 1122 to be detected in real time, facilitating the control of the force between each limit roller 111 and the outer cylinder 300, improving the installation accuracy of the limit rollers 111, and enhancing the smoothness of the outer cylinder 300's operation.

[0048] Optionally, the limiting device for the wind-powered rotor also includes an alarm mechanism, which can issue an alarm based on the detection result of the pressure detection element 122. When the pressure detection element 122 detects that the clamping force of the limiting roller 111 on the outer cylinder 300 exceeds the limit range, an alarm can be issued through the alarm mechanism to promptly prompt the operator to operate the corresponding adjustment component 121 to adjust the clamping force of the limiting roller 111 on the outer cylinder 300, thus preventing the outer cylinder 300 from shaking due to uneven force. It should be noted that the alarm can be an audible alarm, a visual alarm, or an alarm displayed on a monitor with text or image information, etc., and will not be specifically limited here.

[0049] Optionally, the adjusting assembly 121 includes a fixed base 1211, a screw 1212, and a locking member 1213. The fixed base 1211 is fixed to the base 100 or the inner tower 200. The screw 1212 passes through the fixed base 1211 and abuts against the elastic member 13, and the screw 1212 is threadedly connected to the fixed base 1211. The locking member 1213 is used to lock or unlock the screw 1212 and the fixed base 1211. In this embodiment, the locking member 1213 is a nut, and the number of nuts can be set according to requirements and is not limited here. When adjusting the clamping force between the limiting roller 111 and the outer cylinder 300, simply unlock the locking member 1213 and screw the screw 1212 to control the screw 1212 to move forward to increase the clamping force of the limiting roller 111 on the outer cylinder 300, or control the screw 1212 to move backward to decrease the clamping force of the limiting roller 111 on the outer cylinder 300. Meanwhile, when it is necessary to replace the limit roller 111, simply loosen the locking piece 1213 and control the screw 1212 to retract so that the limit roller 111 is separated from the outer cylinder 300, and the limit roller 111 can be removed from the mounting bracket 112. Compared with the existing technology, it is easier to quickly replace the new limit roller 111, greatly reducing the workload and improving work efficiency.

[0050] Optionally, the number of limiting units 1 is even, and the multiple limiting units 1 are evenly distributed at intervals along the outer or inner circumference of the outer cylinder 300. Preferably, the even number of limiting units 1 are arranged opposite each other in pairs along the radial direction of the outer cylinder 300, so that the outer cylinder 300 is subjected to more uniform force and the stability of the outer cylinder 300 at high speed is improved.

[0051] Optionally, the elastic element 13 has a cylindrical structure, with its two ends along its axial direction abutting against the adjusting component 121 and the second end 1122, respectively. The cylindrical structure of the elastic element 13 provides better elasticity and higher contact stability with the adjusting component 121 and the second end 1122 of the mounting bracket 112.

[0052] Optionally, the elastic element 13 includes a main body, with a first transition portion at one end along the second direction. The first transition portion has a frustum-shaped structure, and its large-diameter end is connected to the main body, while its small-diameter end abuts against the adjusting component 121. It should be noted that, to ensure the elastic effect of the elastic element 13, the diameter of the main body of the elastic element 13 is typically larger, while the size of the adjusting component 121 is smaller. This arrangement, by adapting the small-diameter end of the first transition portion to the adjusting component 121, improves the contact stability between the elastic element 13 and the adjusting component 121, which is beneficial for improving the elastic effect of the elastic element 13 and extending its service life.

[0053] Preferably, the diameter of the large-diameter end of the first adapter is the same as the diameter of the main body, the diameter of the small-diameter end of the first adapter is the same as the diameter of the screw 1212, and the contact area between the first adapter and the screw 1212 is equal to the cross-sectional area of ​​the small-diameter end of the first adapter (the cross-section is a section perpendicular to the axial direction of the first adapter), so as to make the contact stability between the elastic member 13 and the adjusting assembly 121 higher.

[0054] Optionally, a second transition portion is provided at one end of the main body along the second direction. The second transition portion has a frustum-shaped structure, and the large-diameter end of the second transition portion is connected to the main body, while the small-diameter end of the second transition portion abuts against the second end 1122. It should be noted that, in order to ensure the elastic effect of the elastic element 13, the diameter of the main body of the elastic element 13 is usually larger, while the size of the second end 1122 of the mounting bracket 112 is smaller. With this arrangement, the contact stability between the elastic element 13 and the second end 1122 of the mounting bracket 112 can be improved by adapting the small-diameter end of the second transition portion to the second end 1122 of the mounting bracket 112, which is beneficial to improving the elastic effect of the elastic element 13 and extending the service life of the elastic element 13.

[0055] Preferably, the diameter of the large-diameter end of the second adapter is the same as the diameter of the main body, the diameter of the small-diameter end of the second adapter is the same as the thickness of the second end 1122 of the mounting bracket 112, and the contact area between the second adapter and the second end 1122 of the mounting bracket 112 is equal to the cross-sectional area of ​​the small-diameter end of the second adapter (the cross-section is a section perpendicular to the axial direction of the second adapter), so as to make the contact stability between the elastic member 13 and the second end 1122 of the mounting bracket 112 higher.

[0056] This embodiment also provides a wind-powered propulsion system, including the limiting device for the wind-powered propulsion rotor as described above.
