Description

Technical Field

[0001] This utility model relates to the field of sail rotor technology, and more specifically, it relates to a sail rotor cage. Background Technology

[0002] A sail rotor is a ship auxiliary propulsion device based on the Magnus effect. It generates thrust perpendicular to the wind direction by rotating a cylindrical rotor, providing additional power to the ship and reducing fuel consumption and carbon emissions. Sail rotors, which are manufactured by fiber winding, are usually placed on a cage to support the sail rotor and maintain its shape.

[0003] Existing sail rotor cages typically provide support for sail rotors through an arc-shaped bracket that fits against the outer ring of the sail rotor. However, such sail rotor cages are only suitable for storing sail rotors of a single size and cannot be used for storing sail rotors of other sizes. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a sail rotor holder that can be used to store sail rotors of different sizes.

[0005] To achieve the above objectives, the technical solution of this utility model is to provide a sail rotor cage, comprising: A bottom support, wherein the length direction of the bottom support is a first direction, and the width direction of the bottom support is a second direction perpendicular to the first direction; The support mechanism includes at least two sets of support components spaced apart along the first direction. Each set of support components includes two centrally symmetrically arranged support units. The two support units of the same set of support components are movably mounted on the bottom bracket along the second direction. Each support unit includes an adjusting member movably mounted on the bottom bracket, an L-shaped rotating frame rotatably connected to the adjusting member via a first rotating shaft, and two support wheels rotatably connected to both ends of the rotating frame via two second rotating shafts. The axial directions of the first rotating shaft and the second rotating shaft are both along the second direction. A drive mechanism is connected to the adjusting member, and the drive mechanism is used to drive the adjusting member to move along the second direction.

[0006] Preferably, the sail rotor retainer further includes two servo motors, which are respectively fixedly mounted on two adjusting members of the same set of support components. The output ends of the two servo motors are respectively driven connected to two first rotating shafts of the same set of support components. The first rotating shafts are rotatably connected to the adjusting members and fixedly connected to the rotating frame. This design is beneficial for the long-term storage of the sail rotor.

[0007] Preferably, the bottom support includes two sets of parallel longitudinal frames and at least two sets of parallel transverse frames. The longitudinal frames are oriented along the first direction, and the transverse frames are oriented along the second direction. Both ends of the transverse frames are fixedly connected to the two longitudinal frames, and the adjusting member is movably mounted on the transverse frames. This design provides stable support for the adjusting member via the transverse frames, facilitating position adjustment.

[0008] Preferably, the transverse frame includes two parallel I-beams, the length direction of which is along the second direction. The adjusting component includes a slide block, the bottom of which is fixedly connected to two sliders. The two sliders are slidably connected to the upper flanges of the two I-beams that are close to each other. This design helps ensure that the drive mechanism drives the slide block to slide stably along the second direction.

[0009] Preferably, the driving mechanism includes a driving assembly, a third rotating shaft, and a gear. The driving assembly is mounted on the bottom bracket, the third rotating shaft is rotatably mounted on the driving assembly, and the gear is fixedly sleeved on the outer ring of the third rotating shaft. A rack extending along the second direction is fixedly connected to one of the sliders of the support unit. The number of gears, third rotating shafts, and racks is the same, and the gears and racks are meshed one-to-one. The driving assembly is used to drive all the third rotating shafts to rotate synchronously and in phase. This design, by driving the third rotating shafts and gears to rotate synchronously and in phase through the driving assembly, allows for the position adjustment of all support units.

[0010] Preferably, the drive assembly includes a fixed frame, sprockets, a chain, and a stepper motor. The number of fixed frames, sprockets, and gears is consistent and corresponds one-to-one. The fixed frame is fixedly connected to the transverse frame. The third rotating shaft is rotatably mounted on the fixed frame. The sprockets are fixedly sleeved on the outer ring of the third rotating shaft. All sprockets are meshed with the chain. The stepper motor is fixedly mounted on one of the fixed frames, and the output end of the stepper motor is driven by the third rotating shaft. In this design, the stepper motor drives one of the third rotating shafts and sprockets to rotate. This sprocket drives the other sprockets and the third rotating shaft to rotate via the chain, thereby making all the third rotating shafts rotate synchronously and in the same phase.

[0011] Preferably, the I-beam has through holes. This design facilitates the installation and transmission of the chain.

[0012] Preferably, the slide includes a pad and a mounting base. The pad is fixedly connected to the slider, the mounting base is fixedly mounted on the pad, the servo motor is fixedly mounted on the mounting base, and the first rotating shaft is rotatably connected to the mounting base. This design avoids interference between the sail rotor and the bottom support.

[0013] The beneficial effects of this utility model are as follows: By using the sail rotor retainer described in this utility model, the distance between two support units in the same set of support components can be adjusted by the drive mechanism, and the support wheels of the support units can provide support for the sail rotor. This allows the sail rotor retainer to be adapted to sail rotors of different sizes, thus improving the applicability of the sail rotor retainer. Attached Figure Description

[0016] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0017] To better understand this utility model, the following is in conjunction with... Figures 1-9 This invention provides a detailed description of a sail rotor cage.

[0018] Example 1: like Figures 1-4 As shown, a sail rotor cage includes: Bottom bracket 1, the length direction of bottom bracket 1 is a first direction, and the width direction of bottom bracket 1 is a second direction perpendicular to the first direction; The support mechanism 2 includes at least two sets of support components 20 spaced apart along a first direction. Each set of support components 20 includes two centrally symmetrically arranged support units 200. The two support units 200 of the same set of support components 20 are movably arranged on the bottom bracket 1 along a second direction. The support unit 200 includes an adjusting member 210 movably arranged on the bottom bracket 1, an L-shaped rotating frame 230 rotatably connected to the adjusting member 210 via a first rotating shaft 220, and two support wheels 250 rotatably connected to the two ends of the rotating frame 230 via two second rotating shafts 240 respectively. The axial directions of the first rotating shaft 220 and the second rotating shaft 240 are both along the second direction. The drive mechanism 3 is connected to the adjusting member 210 and is used to drive the adjusting member 210 to move along the second direction.

[0019] It should be noted that the two support units 200 of the same set of support components 20 are symmetrically arranged about the center of the symmetry plane along the length direction of the bottom bracket 1. The adjusting member 210 can achieve relative displacement with the bottom bracket 1 through one of the sliding connection, roller connection, and ball screw connection. The driving mechanism 3 drives the two adjusting members 210 of the same set of support components 20 to move closer or further away from each other, thereby driving the corresponding rotating frame 230 and support wheel 250 to move, and completing the adjustment of the distance between the two support units 200 to adapt to sail rotors of different sizes. The sail rotor, which is wound with fibers, has a certain strength and elasticity. When subjected to external force, the sail rotor tends to maintain its cylindrical shape. During the process of placing the sail rotor on the support mechanism 2, when the sail rotor comes into contact with the support wheel 250, the rotating frame 230 rotates adaptively under the pressure of the sail rotor until the outer ring of all the support wheels 250 is in contact with the outer ring of the sail rotor. The four support wheels 250 of the same support component 20 provide support to the sail rotor in four directions in the circumferential direction, thereby maintaining the shape of the sail rotor in the vicinity of the support component 20. And because the sail rotor is elastic, when the sail rotor is placed, the sail rotor maintains its initial cylindrical state. In addition, after the sail rotor is placed on the sail rotor holder, a support frame can be installed inside the sail rotor to help maintain the shape of the sail rotor.

[0020] In this embodiment, five sets of support components 20 are provided, and the five sets of support components 20 are linearly arrayed along the first direction to provide uniform support for the sail rotor, thereby helping to maintain the shape of the sail rotor.

[0021] By using the sail rotor retainer of this utility model, the distance between two support units 200 in the same set of support components 20 can be adjusted by the drive mechanism 3, and the support wheel 250 of the support unit 200 can provide support for the sail rotor. This allows the sail rotor retainer to be adapted to sail rotors of different sizes, thus improving the applicability of the sail rotor retainer.

[0022] Example 2: As an optimization of Example 1, such as Figure 1 and Figure 4 As shown, the sail rotor retainer also includes two servo motors 4. The two servo motors 4 are respectively fixedly installed on two adjusting members 210 of the same set of support components 20. The output ends of the two servo motors 4 are respectively driven connected to two first rotating shafts 220 of the set of support components 20. The first rotating shafts 220 are rotatably connected to the adjusting members 210 and are fixedly connected to the rotating frame 230.

[0023] It should be noted that after all the adjusting components 210 are adjusted to the first preset position by the drive mechanism 3, the two servo motors 4 drive the two first rotating shafts 220 of one set of support components 20 to rotate, thereby driving the corresponding rotating frame 230, second rotating shaft 240 and support wheel 250 to rotate synchronously to the second preset position. At the second preset position, the diameter of the smallest circle tangent to the outer ring of the four support wheels 250 of the set of support components 20 is equal to the outer ring diameter of the sail rotor. With this design, the angle of the two rotating frames 230 of one set of support components 20 is actively adjusted by the servo motors 4, so that the four support wheels 250 of the set of support components 20 can maintain the shape of the sail rotor. The other rotating frames 230 are adaptively adjusted during the placement of the sail rotor, which is beneficial for the long-term storage of the sail rotor. If the servo motors 4 are not set, all the first rotating shafts 220 will not have a structure to limit their own rotation. The sail rotor may be deformed if stored on the sail rotor holder for a long time, which is not conducive to the long-term storage of the sail rotor.

[0024] Example 3: As an optimization of Example 2, such as Figure 1 and Figure 2 As shown, the bottom support 1 includes two sets of parallel longitudinal frames 110 and at least two sets of parallel transverse frames 120. The length direction of the longitudinal frames 110 is along a first direction, and the length direction of the transverse frames 120 is along a second direction. The two ends of the transverse frames 120 are fixedly connected to the two longitudinal frames 110 respectively, and the adjusting member 210 is movably disposed on the transverse frame 120.

[0025] It should be noted that the adjusting member 210 can achieve relative displacement with the transverse frame 120 through one of the following methods: sliding connection, roller connection, or ball screw connection. The driving mechanism 3 drives the adjusting member 210 to move on the transverse frame 120. During this process, the transverse frame 120 provides stable support for the adjusting member 210, which facilitates the position adjustment of the adjusting member 210.

[0026] In this embodiment, the number of horizontal frames 120 and support components 20 are the same and correspond one-to-one. That is, there are also five sets of horizontal frames 120, and the horizontal frames 120 are linearly arrayed along the first direction. The five support components 20 are respectively movably mounted on the five horizontal frames 120.

[0027] Example 4: As an optimization of Example 3, such as Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the transverse frame 120 includes two parallel I-beams 121 with their length direction along the second direction. The adjusting member 210 includes a slide 211 with two sliders 212 fixedly connected to the bottom of the slide 211. The two sliders 212 are slidably connected to the upper flanges of the two I-beams 121 that are close to each other.

[0028] It should be noted that by setting the I-beam 121 and the slider 212, it is beneficial to ensure that the drive mechanism 3 drives the slide block 211 to slide stably in the second direction.

[0029] Example 5: As an optimization of Example 4, such as Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the drive mechanism 3 includes a drive assembly 310, a third rotating shaft 320, and a gear 330. The drive assembly 310 is mounted on the bottom bracket 1, the third rotating shaft 320 is rotatably mounted on the drive assembly 310, and the gear 330 is fixedly sleeved on the outer ring of the third rotating shaft 320. A rack 213 extending in the second direction is fixedly connected to one of the sliders 212 of the support unit 200. The number of gears 330, third rotating shafts 320, and racks 213 is the same, and the gears 330 and racks 213 are meshed one by one. The drive assembly 310 is used to drive all the third rotating shafts 320 to rotate synchronously and in the same phase.

[0030] It should be noted that the two racks 213 of the same set of support components 20 are symmetrically arranged about the center of the plane of symmetry of the bottom bracket 1 along the length direction. The drive component 310 can be set as a synchronous belt and synchronous pulley structure or a sprocket and chain structure. The drive component 310 drives all the third rotating shafts 320 to rotate synchronously and in the same phase, thereby driving all the gears 330 to rotate synchronously and in the same phase, and then driving all the racks 213 to move. The two racks 213 of the same set of support components 20 are closer to each other or further away from each other, so that the two adjusting parts 210 of the same set of support components 20 are closer to each other or further away from each other. By driving the third rotating shafts 320 and gears 330 to rotate synchronously and in the same phase through the drive component 310, the position adjustment of all support units 200 can be completed, and the adjustment is convenient and quick.

[0031] Example 6: As an optimization of Example 5, such as Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the drive assembly 310 includes a fixed frame 311, a sprocket 312, a chain 313, and a stepper motor 314. The number of fixed frames 311, sprockets 312, and gears 330 are the same and correspond one-to-one. The fixed frame 311 is fixedly connected to the transverse frame 120. The third rotating shaft 320 is rotatably mounted on the fixed frame 311. The sprockets 312 are fixedly sleeved on the outer ring of the third rotating shaft 320. All sprockets 312 are meshed with the chain 313. The stepper motor 314 is fixedly mounted on one of the fixed frames 311, and the output end of the stepper motor 314 is drivenly connected to the third rotating shaft 320.

[0032] It should be noted that one end of the fixed frame 311 is fixedly connected to the web of one of the I-beams 121 of one of the transverse frames 120, and the other end of the fixed frame 311 is fixedly connected to the web of another I-beam 121 of the same transverse frame 120. The stepper motor 314 drives one of the third rotating shafts 320 to rotate and the sprocket 312 fixedly sleeved on the third rotating shaft 320 to rotate. The sprocket 312 drives the other sprockets 312 and the third rotating shaft 320 to rotate synchronously and in the same phase through the chain 313, so that all the third rotating shafts 320 rotate synchronously and in the same phase.

[0033] In this embodiment, the sprocket 312 is located below the gear 330 to avoid interference with the slide block 211, and the chain 313 is in the shape of a square ring.

[0034] Example 7: As an optimization of Example 6, such as Figure 5 As shown, the I-beam 121 has a through hole 1211.

[0035] It should be noted that the perforation 1211 is located on the web of the I-beam 121, and the size of the perforation 1211 is slightly larger than the cross-sectional size of the chain 313. The perforation 1211 is provided to facilitate the installation and transmission of the chain 313.

[0036] Example 8: As an optimization of Example 7, such as Figure 3 and Figure 4 As shown, the slide 211 includes a pad 2111 and a mounting base 2112. The pad 2111 is fixedly connected to the slide 212, the mounting base 2112 is fixedly mounted on the pad 2111, the servo motor 4 is fixedly mounted on the mounting base 2112, and the first rotating shaft 220 is rotatably connected to the mounting base 2112.

[0037] It should be noted that the mounting base 2112 is fixedly mounted on the pad 2111 by bolts and nuts. By setting the pad, interference between the sail rotor and the bottom bracket 1 can be avoided.
