Description

[Technical Field]

[0001] This application claims priority from a Chinese patent application bearing application number 202310071901.9, filed with the China Patent Office on February 7, 2023, the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the technical field of wind propulsion auxiliary rotors, for example, to a position regulation device for a wind propulsion auxiliary rotor and a wind propulsion auxiliary system. [Background technology]

[0003] The working principle of the wind propulsion auxiliary rotor is the Magnus effect, and a ship equipped with a wind propulsion auxiliary rotor can generate forward thrust on the ship by adjusting the rotation direction of the rotor in crosswind or angled wind conditions, thereby achieving the effect of propulsion assistance.

[0004] A wind propulsion auxiliary rotor generally comprises a base, an inner tower fixed to the base, and an outer cylinder rotatably fitted around the inner tower. Due to the influence of manufacturing and the usage environment, there is a deviation in the coaxiality between the outer cylinder axis and the inner tower axis. In order to limit the radial runout of the outer cylinder, a plurality of positioning roller devices are generally provided around the outer cylinder, and the positioning roller devices include positioning rollers that abut against the wall of the outer cylinder to limit the radial runout of the outer cylinder.

[0005] Wind propulsion auxiliary rotors are usually very tall, with a maximum diameter of 6 meters and a maximum height of nearly 40 meters. The outer cylinder must rotate at high speed around the central axis of the inner tower, and since the linear speed of rotation of the outer cylinder is high and the moment of inertia of the outer cylinder is very large, very high requirements are placed on the position-regulating roller device at the bottom of the outer cylinder to ensure stable and high-speed operation of the outer cylinder and reduce the amount of shaking of the outer cylinder.

[0006] In the positioning roller devices of the related art, the roller shafts of the positioning rollers are all slidably mounted on the base, which results in poor contact stability between the positioning rollers and the outer cylinder, a large amount of assembly work, and difficulty in controlling installation accuracy, etc. If the assembly error of multiple positioning roller devices is too large, the outer cylinder will experience severe vibration during high-speed operation, increasing the roller load and directly affecting its service life. At the same time, it is impossible to ensure continuous and stable operation of the rotor, which not only prevents the outer cylinder from meeting the design requirements, but also generates large internal stresses and torsional deformations locally in the outer cylinder, potentially causing a safety accident for the rotor. Summary of the Invention

[0007] The present application provides a position control device for a wind propulsion auxiliary rotor and a wind propulsion auxiliary system that has a simple structure, is easy to assemble and adjust, and improves the contact stability between the position control roller and the outer cylinder, thereby ensuring stability during high-speed operation of the outer cylinder.

[0025] The following describes embodiments of the present application, examples of which are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are merely illustrative and are intended to help interpret the present application, and should not be understood as limiting the present application.

[0026] As shown in FIGS. 1 to 6, this embodiment is a position regulating device for a wind-propelled auxiliary rotor, the wind-propelled auxiliary rotor comprising a base 100, an inner tower 200 fixed to the base 100, and an outer cylinder 300 rotatably fitted to the outside of the inner tower 200, the position regulating device for the wind-propelled auxiliary rotor comprising a plurality of position regulating units 1 distributed along the outer periphery or the inner periphery of the outer cylinder 300, each position regulating unit 1 being a roller mechanism 11 comprising a position regulating roller 111 and a mounting bracket 112, the mounting bracket 112 being a first direction, Provided is a position control device comprising: a roller mechanism (11) having one end (1121) and a second end (1122), the first end (1121) being rotatably mounted on a base (100) or an inner tower (200), a position control roller (111) being rotatably mounted on the second end (1122), and the outer peripheral surface of the position control roller (111) abutting against the outer wall or inner wall of an outer tube (300); an adjustment mechanism (12) having an adjustment assembly (121) having one end abutting against the second end (1122) for adjusting the acting force between the position control roller (111) and the outer tube (300); and an elastic member (13) sandwiched between the adjustment assembly (121) and the second end (1122).

[0027] The outer surface of the position restriction roller 111 abuts against the outer wall or inner wall of the outer cylinder 300, and the adjustment assembly 121 can be used to adjust the force between the position restriction roller 111 and the outer cylinder 300 so that the force between each position restriction roller 111 and the outer cylinder 300 is approximately equal. The elastic member 13 allows the position restriction roller 111 to have a certain range of displacement, absorbing and cushioning the load generated when the outer cylinder 300 operates at high speed, ensuring stability when the outer cylinder 300 operates at high speed and contributing to extending the service life of the position restriction 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 position control roller 111 is rotatably mounted on the second end 1122 of the mounting bracket 112. Compared to the related art, this not only makes it easier to install and remove the position control roller 111, but also makes it easier to adjust the pressing force of the position control roller 111, thereby improving the contact stability between the position control roller 111 and the outer tube 300.

[0028] Whether the position regulating units 1 are distributed on the outer periphery or the inner periphery of the outer cylinder 300 can be determined depending on the diameter of the outer cylinder 300. To facilitate the installation of the position regulating units 1 and ensure stable contact between the position regulating rollers 111 and the outer cylinder 300, when the diameter of the outer cylinder 300 is small, multiple position regulating units 1 are attached to the base 100, in other words, multiple position regulating units 1 are distributed along the outer circumference of the outer cylinder 300, the first end 1121 of the mounting bracket 112 is rotatably mounted on the base 100, and the outer surfaces of the position regulating rollers 111 abut against the outer wall of the outer cylinder 300; when the diameter of the outer cylinder 300 is large, multiple position regulating units 1 are attached to the inner tower 200, in other words, multiple position regulating units 1 are distributed along the inner circumference of the outer cylinder 300, the first end 1121 of the mounting bracket 112 is rotatably mounted on the inner tower 200, and the outer surfaces of the position regulating rollers 111 abut against the inner wall of the outer cylinder 300.

[0029] Preferably, the first end 1121 of the mounting bracket 112 is provided with a rotating shaft 1123, the first end of which is fixedly connected to the first end 1121 and the second end of which is rotatably connected to the base 100 or the inner tower 200. For example, in order to improve the smoothness of rotation of the mounting bracket 112, the second end of the rotating shaft 1123 may be rotatably connected to the base 100 or the inner tower 200 via a rotation support member, such as a bearing. With this configuration, the rotating connection between the mounting bracket 112 and the base 100 is realized, and when adjusting the pressing force between the position limiting roller 111 and the outer cylinder 300, the position limiting roller 111 can flexibly move in the radial direction. This is advantageous for accurately adjusting the pressing force of the position limiting roller 111 on the outer cylinder 300 and improves the stability of contact between the position limiting roller 111 and the outer cylinder 300.

[0030] Preferably, the adjustment mechanism 12 further includes a pressure sensing member 122, such as a load cell, configured to detect the pressure between the adjustment assembly 121 and the second end 1122. In this manner, the pressure between the adjustment assembly 121 and the second end 1122 can be detected in real time by the pressure sensing member 122, which facilitates controlling the forces acting between the position restriction rollers 111 and the outer cylinder 300 to be consistent, which is advantageous for improving the installation accuracy of the position restriction rollers 111 and improving the operational stability of the outer cylinder 300.

[0031] Preferably, the position control device for a wind propulsion auxiliary rotor further includes an alarm mechanism 400 that issues an alarm notification in response to the detection result of the pressure detection member 122. When the pressure detection member 122 detects that the pressing force of the position control roller 111 on the outer cylinder 300 exceeds the limit range, the alarm mechanism 400 can issue an alarm notification, and immediately notify an operator to operate the corresponding adjustment assembly 121 to adjust the pressing force of the position control roller 111 on the outer cylinder 300, thereby avoiding problems such as shaking caused by uneven force applied to the outer cylinder 300. The alarm notification may be an audio alarm, an alarm using a light, or may be in the form of text displayed on a display, image information, or the like, and is not limited thereto.

[0032] Preferably, the adjustment assembly 121 includes a fixed seat 1211 fixed to the base 100 or the inner tower 200, a screw 1212 drilled into the fixed seat 1211, abutted against the elastic member 13, and screwed into the fixed seat 1211, and a locking member 1213 configured to lock or unlock the screw 1212 relative to the fixed seat 1211. In this embodiment, the locking member 1213 is a nut, and the number of nuts may be set according to needs and is not limited herein. To adjust the pressing force between the position limiting roller 111 and the outer cylinder 300, simply unlock the locking member 1213 and turn the screw 1212 to advance the screw 1212 to increase the pressing force of the position limiting roller 111 against the outer cylinder 300, or to retreat the screw 1212 to decrease the pressing force of the position limiting roller 111 against the outer cylinder 300. At the same time, when it becomes necessary to replace the position restriction roller 111, the position restriction roller 111 can be removed from the mounting bracket 112 simply by loosening the locking member 1213 and controlling the screw 1212 to retract, thereby separating the position restriction roller 111 from the outer cylinder 300. Compared to the related art, this makes it easier to quickly replace the position restriction roller 111 with a new one, significantly reducing the amount of work and improving work efficiency.

[0033] Preferably, the number of position regulating units 1 is an even number, and the position regulating units 1 are uniformly distributed at intervals along the outer or inner circumference of the outer cylinder 300. Preferably, the even number of position regulating units 1 are arranged two by two opposite each other along the radial direction of the outer cylinder 300, which makes the force applied to the outer cylinder 300 more uniform and improves the stability of the outer cylinder 300 during high-speed operation.

[0034] Preferably, the elastic member 13 has a cylindrical structure, and a first end and a second end of the elastic member 13 along the axial direction thereof abut against the adjustment assembly 121 and the second end 1122, respectively. The cylindrical elastic member 13 has better elasticity and higher contact stability with the adjustment assembly 121 and the second end 1122 of the mounting bracket 112.

[0035] Preferably, the elastic member 13 includes a main body 131, and a first adapter part 1311 having a truncated cone shape at a first end of the main body 131 in the second direction, the first adapter part 1311 having a large diameter end connected to the main body 131 and a small diameter end abutting the adjustment assembly 121. To ensure the elastic effect of the elastic member 13, the main body 131 of the elastic member 13 usually has a large diameter and the adjustment assembly 121 is small in size. With this configuration, the small diameter end of the first adapter part 1311 fits into the adjustment assembly 121, improving the contact stability between the elastic member 13 and the adjustment assembly 121, which is advantageous for improving the elastic effect of the elastic member 13 and extending the service life of the elastic member 13.

[0036] Preferably, the diameter of the large diameter end of the first adapter part 1311 is the same as the diameter of the main body part 131, the diameter of the small diameter end of the first adapter part 1311 is the same as the diameter of the screw 1212, and the contact area between the first adapter part 1311 and the screw 1212 is equal to the cross-sectional area of ​​the small diameter end of the first adapter part 1311 (the cross-section is a cross section perpendicular to the axial direction of the first adapter part 1311), thereby providing greater contact stability between the elastic member 13 and the adjustment assembly 121.

[0037] Preferably, a second end of the main body portion 131 in the second direction is provided with a second adapter portion 1312 having a truncated cone shape, with a large diameter end connected to the main body portion 131 and a small diameter end abutting the second end 1122. In order to ensure the elastic effect of the elastic member 13, the diameter of the main body portion 131 of the elastic member 13 is usually large and the size of the second end 1122 of the mounting bracket 112 is small. With this configuration, the small diameter end of the second adapter portion 1312 fits into the second end 1122 of the mounting bracket 112, thereby improving the contact stability between the elastic member 13 and the second end 1122 of the mounting bracket 112, which is advantageous for improving the elastic effect of the elastic member 13 and extending the service life of the elastic member 13.

[0038] Preferably, the diameter of the larger diameter end of the second adapter part 1312 is the same as the diameter of the main body part, the diameter of the smaller diameter end of the second adapter part 1312 is the same as the thickness of the second end 1122 of the mounting bracket 112, and the contact area between the second adapter part 1312 and the second end 1122 of the mounting bracket 112 is equal to the cross-sectional area of ​​the smaller diameter end of the second adapter part 1312 (the cross-section is a cross section perpendicular to the axial direction of the second adapter part 1312), thereby increasing the contact stability between the elastic member 13 and the second end 1122 of the mounting bracket 112.
