Description

Technical Field

[0001] This utility model relates to the field of ship roll reduction technology, specifically to a carrier, a roll reduction gyroscope having the same, and a ship. Background Technology

[0002] A roll-damping gyroscope is a device used to reduce roll on a ship's hull. When in operation, its flywheel rotates not only around its own axis of rotation but also oscillates back and forth around a precession axis perpendicular to its own axis of rotation. By applying a control torque along the precession axis of the flywheel, a roll-damping torque is output in a direction orthogonal to both the rotation and precession axes, thus suppressing the ship's roll. The roll-damping gyroscope has a base that not only indirectly mounts the flywheel but also needs to be securely connected to the hull to transmit the roll-damping torque to the hull. Therefore, the control system of the roll-damping gyroscope must avoid the screw mounting space required to fix the base to the hull during installation, which makes the installation of the control system challenging. Summary of the Invention

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] To address this, this utility model provides a carrier that offers an installation position on the upper circumferential side of the flywheel, allowing accessories to be installed on the upper circumferential side of the flywheel and making use of the space there. This avoids the installation difficulties encountered when accessories such as the control system of existing anti-roll gyroscopes are arranged on the base due to the need to avoid the installation space of the base connecting screws.

[0005] The carrier of this utility model embodiment is disposed on the outer periphery of the upper part of the flywheel of the anti-roll gyroscope. The precession axis of the flywheel extends in the vertical direction. The cross-sectional area of ​​the cavity of the carrier gradually increases from top to bottom. The lower end of the cavity is located between the rotation axis of the flywheel and the upper end of the flywheel.

The flywheel is connected to the rotary support through the bearing so that the flywheel can rotate along a precession axis extending vertically. A carrier is provided on the outer periphery of the upper part of the flywheel. The carrier is as described in any of the above embodiments. The periphery of the lower end of the carrier is connected to the support. An accessory is fitted onto the side of the carrier away from the flywheel, and the projection of the accessory on the horizontal plane at least partially coincides with the projection of the flywheel's rotation trajectory on the horizontal plane.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] like Figure 1 As shown, the carrier 100 in this embodiment of the utility model can be an integral structure. For example, the carrier 100 can be integrally stamped from sheet metal or other plates. In some other embodiments, the carrier 100 can also be processed by casting or other methods, or it can be formed by bending and welding sheet metal.

[0023] The carrier 100 can be a cylindrical structure, meaning its top can be open. In use, the carrier 100 can be mounted on top of the flywheel 400 of the anti-roll gyroscope, and the carrier 100 can cover the outer periphery of the upper part of the flywheel 400. The precession axis of the flywheel 400 extends in the vertical direction.

[0024] The internal space of the carrier 100 can form a cavity, and the cross-sectional area of ​​the cavity can gradually increase from top to bottom. For example, the cavity as a whole can be a quadrangular prism, the cross-section of the cavity can be rectangular, and the cross-section of the cavity can gradually increase from top to bottom. This facilitates the insertion of the flywheel 400.

[0025] The flywheel 400 may have a horizontally extending axis of rotation, which can be the axis around which the flywheel 400 rotates. In the vertical direction, the lower end of the cavity may be located between the axis of rotation of the flywheel 400 and the top of the flywheel 400. Specifically, the flywheel 400 can be rotatably assembled via a corresponding bearing 31, in which case the axis of rotation of the flywheel 400 can be considered as the axis of the bearing 31. This allows the pivot of the flywheel 400 to be offset and spaced apart from the carrier 100 in the vertical direction, facilitating the inspection and maintenance of the flywheel 400 and avoiding interference between the pivot and the carrier 100.

[0026] The surface of the carrier 100 facing away from the cavity is used to mount the accessory 500 of the roll stabilizer gyroscope. For example, the upper surface of the carrier 100 can be used to mount the accessory 500, which can specifically be a circuit board, controller, or other functional components of the roll stabilizer gyroscope. Since the cross-sectional area of ​​the cavity of the carrier 100 gradually increases from top to bottom, and the lower end of the cavity is located between the rotation axis of the flywheel 400 and the upper end of the flywheel, the surface of the carrier 100 facing away from the cavity has a relatively gentle slope. At the same time, the carrier 100 is less likely to interfere with the flywheel 400. When the circuit board, driver, or other accessories 500 are mounted on the surface of the carrier 100 facing away from the cavity, the accessories can be supported by a certain upward component force of the carrier 100, and the accessories 500 can be fixed relatively stably.

[0027] Since accessories such as circuit boards and drivers can be mounted on the carrier 100 instead of the base 21 near the flywheel 400, there is no need to avoid the mounting screw positions of the base 21, and there is a large installation space, which avoids the additional space occupied by the accessory 500 and reduces the installation difficulty of the accessory 500.

[0028] In some embodiments, such as Figure 1 As shown, the carrier 100 of this embodiment may include a plurality of carrier plates 12, which are arranged sequentially around the precession axis of the flywheel and form the aforementioned cavity. The plurality of carrier plates 12 may form a polygonal shape with a cross-section, such as a quadrilateral, pentagon, hexagon, heptagon, etc. Each carrier plate 12 may be arranged inclined downwards in a top-to-bottom direction, wherein each carrier plate 12 is inclined outwards from the carrier 100, and the upper surface of each carrier plate 12 forms a mounting surface for assembling accessories for the anti-roll gyroscope.

[0029] It is understandable that the carrier 100 may also be conical, partially spherical, etc.

[0030] In some embodiments, at least a portion of the carrier plate 12 is provided with a perforation, which communicates the cavity with the outside of the carrier plate 12. For example, as Figure 1 As shown, the perforation can be a round hole, and in some other embodiments, it can also be a square hole, an elliptical hole, etc. Each carrier plate 12 can have a perforation, which can penetrate the carrier plate 12 along its thickness direction.

[0031] The perforated design serves two purposes: firstly, it avoids direct contact and interference between the rotating flywheel 400 and the carrier plate 12, ensuring its normal operation; secondly, the rotation of the flywheel 400 drives airflow through the perforated holes, which helps dissipate heat from the circuit board, controller, and other electronic components, thus improving heat dissipation. Additionally, the perforated design also reduces material consumption and weight.

[0032] In some embodiments, the carrier plate 12 is a flat plate with a central area. The distance between the carrier plate 12 and the rotation trajectory of the flywheel 400 is limited at the central area, and the perforation is provided in the central area.

[0033] For example, such as Figure 1 As shown, each carrier plate 12 can be a flat plate, meaning that the carrier plates 12 are generally located in the same plane. The central area can be the region in the middle of the carrier plate 12. When the flywheel 400 rotates, it will form a rotation trajectory. The distance between the rotation trajectory of the carrier plate 12 and the flywheel 400 can be minimized at the central area, and the hollow area can be arranged at the central area, thereby effectively avoiding the situation where the rotating flywheel 400 touches the carrier plate 12.

[0034] In some embodiments, at least partially adjacent joint portions 13 of two carrier plates 12 are provided with notches 14 in the circumferential direction. For example, as Figure 1 As shown, the four carrier plates 12 can form four joint portions 13 in the circumferential direction. The joint portion 13 can be specifically regarded as the connection position or mating position of two adjacent carrier plates 12. Each joint portion 13 can be provided with a notch 14, which can be a rectangular groove, a long groove, a triangular groove, etc. After the carrier 100 is assembled, the notch 14 can be inserted into the drive component 600, thereby avoiding the action of the drive component 600. This also helps to reduce the overall space and improve the space utilization rate.

[0035] In some embodiments, the joining portion 13 includes a first joining section 131 and a second joining section 132, wherein the first joining section 131 is located between the upper end of the carrier plate and the second joining section 132. For example, as Figure 1As shown, depending on the style, the joint portion 13 can be divided into two segments, namely the first joint segment 131 and the second joint segment 132, wherein the first joint segment 131 can be located above the second joint segment 132.

[0036] In the first joint section 131, two adjacent carrier plates 12 are connected. For example, as shown... Figure 1 As shown, at the first joint section 131, the sides of two adjacent carrier plates 12 can be joined together to form an edge. This can enhance the overall structural strength of the carrier 100.

[0037] In the second joint section 132, two adjacent carrier plates 12 are spaced apart to define the notch 14. For example, as Figure 1 As shown, at the second joint section 132, the two sides of two adjacent carrier plates 12 can be separated in the circumferential direction, so that the notch 14 can be formed between the two separated sides of the two carrier plates 12.

[0038] In some embodiments, at least a portion of the notch 14 has an increasing width dimension along the direction from the first engagement segment 131 to the second engagement segment 132.

[0039] For example, such as Figure 1 As shown, the upper half of each notch 14 can be generally triangular, and the width of the notch 14 in the circumferential direction can gradually increase from top to bottom. This part with the gradually changing width can be located in the vertical plane, so as to match the insertion of the drive member 600 in the vertical direction and fully avoid contact and interference with the drive member 600.

[0040] In some embodiments, the carrier 100 further includes a connecting plate whose thickness direction is vertical, and the upper ends of the plurality of carrier plates are all connected to the connecting plate.

[0041] For example, such as Figure 1 As shown, the connecting plate 11 can be a quadrilateral, specifically a square. In other embodiments, the connecting plate 11 can also be a triangle, pentagon, hexagon, heptagon, or other shapes.

[0042] Each of the aforementioned carrier plates 12 is connected to the connecting plate 11. Multiple carrier plates 12 are arranged at intervals along the circumference of the connecting plate 11. Multiple carrier plates 12 and the connecting plate 11 form a cavity for inserting the flywheel 400. At least a portion of the carrier plates 12 are used to mount the accessory 500 of the anti-roll gyroscope on the surface away from the cavity.

[0043] For example, such as Figure 1As shown, when the connecting plate 11 is a square plate, four carrier plates 12 can be provided, matching the number of sides of the connecting plate 11. The four carrier plates 12 can be connected to the four sides of the connecting plate 11 respectively, and the four carrier plates 12 can be arranged at equal intervals along the circumference of the connecting plate 11. Specifically, the top side of each carrier plate 12 can be connected to the corresponding side of the connecting plate 11, and each carrier plate 12 can be arranged inclined downwards from top to bottom, with each carrier plate 12 inclined outwards towards the carrier 100. The connecting plate 11 not only increases the structural strength of the carrier 100 itself, but also can support the attachment 500 of the anti-roll gyroscope. The attachment 500 can be a component of the control system, such as a circuit board, driver, relay, etc., or a component of the cooling system, such as a water pump, water tank, etc.

[0044] In some embodiments, a baffle 15 is provided on the side of the carrier plate 12 away from the connecting plate 11. The baffle 15 is used to connect to or abut against the housing 200 of the anti-roll gyroscope. For example, as Figure 1 As shown, a baffle 15 can be provided at the bottom edge of each carrier plate 12, and the baffle 15 can be integrally formed on the corresponding carrier plate 12. In some other embodiments, the baffle 15 can also be fixed to the carrier plate 12 by welding or other means.

[0045] like Figure 1 As shown, the baffle 15 may include a horizontal section 151 and a vertical section 152, wherein the horizontal section 151 may be arranged horizontally and may be connected to the bottom edge of the carrier plate 12, and the vertical section 152 may be connected to the outer edge of the horizontal section 151, and the vertical section 152 is generally located in a vertical plane.

[0046] During assembly, the vertical section 152 of the baffle 15 can be connected, fixed, or abutted against the inner wall of the housing 200 of the anti-roll gyroscope, which facilitates the assembly of the carrier 100 and improves the overall structural strength.

[0047] The following describes an embodiment of the anti-roll gyroscope of this utility model.

[0048] like Figure 2 As shown, the anti-roll gyroscope of this utility model embodiment includes a carrier 100, a housing 200, a rotation support 300, a flywheel 400, and an accessory 500.

[0049] The housing 200 has a base 21 and a support 24 extending upward from the periphery of the base 21. The slewing support 300 is connected to the bottom of the housing 200. For example, the bottom of the housing 200 may include a base 21, which may be a rectangular plate structure, and the slewing support 300 may be fixed to the base 21. Specifically, the slewing support 300 may include an inner ring and an outer ring, wherein the inner ring may be directly fixedly connected to the base 21, and the outer ring may be fitted around the outer periphery of the inner ring, and the outer ring may rotate freely around the inner ring.

[0050] The flywheel 400 is supported on a bearing 31 and can rotate about a horizontally extending axis of rotation. The flywheel 400 is connected to the slewing support 300 via the bearing 31, so that the flywheel 400 can rotate along a precession axis extending vertically. For example, as... Figure 2 and Figure 3 As shown, two bearing seats 31 can be fixed on the outer ring of the slewing support 300. The two bearing seats 31 can be ear-shaped and can be arranged opposite each other along the radial direction of the slewing support 300. The flywheel 400 can be rotatably mounted between the two bearing seats 31 via a pivot. In use, the flywheel 400 rotates about its horizontally extending axis of rotation. The drive unit 600 controls the flywheel 400 to rotate and oscillate about its vertically extending precession axis by driving the outer ring of the slewing support 300. The anti-roll gyroscope outputs a torque orthogonal to the axis of rotation and the precession axis to the base 21. When the anti-roll gyroscope is installed on a ship, this torque will suppress the ship's rolling, thus achieving the effect of anti-roll.

[0051] The carrier 100 is mounted on the outer periphery of the upper part of the flywheel 400, and the carrier 100 is connected to the support 24 of the housing 200. When the carrier 100 is connected to the circumferential support 24 of the base 21, the carrier 100 can be stably supported. At this time, the lower end of the carrier 100 can be located between the horizontal axis of the flywheel 400 and the upper end of the flywheel 400. The cross-sectional area of ​​the cavity of the carrier 100 gradually increases from top to bottom. The carrier 100 can avoid the flywheel 400 while forming a relatively gentle slope. When the accessory 500 is assembled on the surface of the carrier 100 away from the cavity, there is an upward component force to support the accessory 500. The accessory 500 can be firmly fixed on the carrier 100. At this time, the projection of the accessory 500 on the horizontal plane can at least partially coincide with the projection of the rotation trajectory of the flywheel 400 on the horizontal plane. The accessory 500 can be installed and fixed without occupying additional space on the plane.

[0052] In some embodiments, the support 24 includes a first portion 241 connected to the base 21 and a second portion 242 connected above the first portion 241, the periphery of the lower end of the carrier 100 is connected to the junction of the first portion 241 and the second portion 242, and the attachment 500 is located within the space defined by the carrier 100 and the second portion 242.

[0053] The lower periphery of the carrier 100 connects to the junction of the first part 241 and the second part 242, allowing the supports 24 extending upwards from the base 21 to connect and form a tight whole, thereby improving the overall stability of the supports 24. Simultaneously, the carrier 100, relying on the first part 241, can fix accessories above the base 21, meaning the accessories can be fixed to the outer periphery of the upper part of the flywheel 400. This provides ample installation space for the accessories 500, avoiding the installation difficulties encountered with existing anti-roll gyroscope control systems and other accessories on the base due to the need to avoid the mounting space of the base's connecting screws. Furthermore, the carrier 100 and the second part 242 can form a space to accommodate accessories, fully utilizing the top space of the housing 200. This space also protects the control system's circuit boards, drivers, and other accessories from impact damage.

[0054] In some other embodiments, the support 24 may also include only the first part 241, in which case the carrier 100 may be directly connected to the top side of the first part 241.

[0055] In some embodiments, the anti-roll gyroscope includes a drive member 600, which is mounted on the housing 200. One end of the drive member 600 is connected to the bottom of the housing 200, and the other end of the drive member 600 extends into the notch 14.

[0056] It should be noted that the drive component 600 can be arranged to extend along the vertical direction. The bottom end of the drive component 600 can be connected and fixed to the base 21 at the bottom of the housing 200, and the top end of the drive component 600 can be inserted into the corresponding notch 14. This helps to reduce the assembly height of the carrier 100, thereby further improving the overall space utilization.

[0057] In some embodiments, the housing 200 includes a frame and a cover plate 23. The frame includes a plurality of supports 22, which are arranged horizontally and sequentially along the circumference of the frame. The sides of the plurality of carrier plates away from the connecting plate 11 are respectively connected to or abutted by the plurality of supports 22.

[0058] For example, such as Figure 2 and Figure 3 As shown, the overall frame can be a rectangular structure, specifically comprising four columns. The four columns can be fixed at the four corners of the base 21, and each column extends vertically. The connecting members 22 can be rod-shaped, and there can be four connecting members 22. Each connecting member 22 can be connected between two corresponding columns, and the four connecting members 22 can be roughly located at the same horizontal level.

[0059] When assembling the carrier 100, the bottom edges of the four carrier plates 12 of the carrier 100 can respectively abut against the inner side of the corresponding support member 22, thereby facilitating the installation and fixing of the carrier 100. Secondly, the carrier 100 can also be used to connect the four support members 22, thereby improving the overall structural strength and stability of the frame.

[0060] Cover plate 23 covers the outer perimeter of the frame. For example, as Figure 4 As shown, multiple cover plates 23 are provided, which may include upper cover plates 231 and lower cover plates 232. There may be four upper cover plates 231, which can be fixed to the four sides of the frame and are all located above the four support members 22. The four lower cover plates 232 can be fixed to the four sides of the frame and are all located below the four support members 22.

[0061] The top side of the frame can also be sealed by a corresponding top cover plate 23. This achieves a seal on the housing 200, preventing damage to accessories 500 and other components from foreign objects.

[0062] In some other embodiments, the four carrier plates 12 of the carrier 100 may also be connected and fixed to the corresponding lower cover plates 232 respectively.
