Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a rudder angle signal feedback device and a ship. Background Technology

[0002] Ships play a vital role in modern transportation and long-distance logistics. Ships typically adjust their direction using rudders. A single steering gear usually houses both the rudder angle feedback device and the rudder angle indicator transmitter of an automatic steering system. The installation position and accuracy of these two devices directly affect the accurate operation of the steering system, control system commands, and instrument displays, making them crucial for ensuring safe navigation and precise control. In current technology, the rudder angle feedback device and rudder angle transmitter on a rotary steering gear are usually mounted non-coaxially, leading to signal deviations that negatively impact navigation safety and control precision.

[0003] Therefore, a rudder angle signal feedback device and a ship are needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a rudder angle signal feedback device and a ship that can eliminate the signal deviation between the rudder angle feedback device and the rudder angle transmitter, thereby ensuring the navigation safety and control accuracy of the ship.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The rudder angle signal feedback device includes:

[0007] A rudder angle transmitter, the rudder angle transmitter having a first angle deflection rod;

[0008] The rudder angle feedback device is located on both sides of the servo motor, and the rotation center point of the rudder angle transmitter, the rotation center point of the rudder angle feedback device and the rotation center point of the servo motor are on the same straight line. The rudder angle feedback device has a second angle deflection rod.

[0009] Mounting components are mounted on the servo motor and are located on the line connecting the rotation center point of the servo motor and the zero angle line;

[0010] A first link, one end of which is rotatably connected to the mounting assembly, and the other end of which is rotatably connected to the first angle deflection rod;

[0011] The second link has one end rotatably connected to the mounting assembly and the other end rotatably connected to the second angle deflection rod.

[0012] The line connecting the rotation center point of the rudder angle feedback device and the rotation center point of the rudder angle transmitter, the first angle deflection rod, the first connecting rod, the second connecting rod, and the second angle deflection rod form a parallelogram structure.

[0013] In some embodiments, the mounting assembly includes a mounting post and a spacer, the mounting post being disposed on the servo, the spacer being sleeved on the mounting post, and the spacer being located between the first link and the second link.

[0014] In some embodiments, the servo motor has a threaded hole, the lower end of the mounting column has an external thread, and the mounting column is screwed into the threaded hole.

[0015] In some embodiments, the mounting assembly further includes a locking element disposed at the end of the mounting post away from the servo motor.

[0016] In some embodiments, the first link includes a first rod portion, an intermediate rod portion, and a second rod portion connected in sequence, wherein the first rod portion is rotatably connected to the mounting assembly, and the second rod portion is rotatably connected to the first angle deflection rod.

[0017] In some embodiments, the two ends of the intermediate rod are provided with a first threaded hole and a second threaded hole. The first rod has a first external thread, and the second rod has a second external thread. The first rod is connected to the first threaded hole through the first external thread, and the second rod is connected to the second threaded hole through the second external thread.

[0018] In some embodiments, the first external thread and the second external thread have opposite directions of rotation.

[0019] In some embodiments, a first mounting base is also included, on which the rudder angle transmitter is disposed.

[0020] In some embodiments, a second mounting base is also included, on which the rudder angle feedback device is disposed.

[0021] The vessel includes a hull and a rudder angle signal feedback device as described above, wherein the rudder angle signal feedback device is disposed in the hull.

[0022] The beneficial effects of this invention are:

[0023] This invention provides a rudder angle signal feedback device, in which a rudder angle transmitter and a rudder angle feedback device are located on opposite sides of a servo motor. The rotation center points of the rudder angle transmitter, the rudder angle feedback device, and the servo motor's rotation center point are collinear. A mounting assembly is mounted on the servo motor and is located on the line connecting the servo motor's rotation center point and the zero-angle line. One end of a first connecting rod is rotatably connected to the mounting assembly, and the other end is rotatably connected to a first angle deflection rod. One end of a second connecting rod is rotatably connected to the mounting assembly, and the other end is rotatably connected to a second angle deflection rod. The line connecting the rotation center points of the rudder angle feedback device and the rudder angle transmitter, the first angle deflection rod, the first connecting rod, the second connecting rod, and the second angle deflection rod form a parallelogram structure. During servo motor rotation, the mounting assembly drives the first and second angle deflection rods to rotate via the first and second connecting rods, and the rudder angle transmitter and rudder angle feedback device acquire the corresponding rudder angle. Since the line connecting the rotation center point of the rudder angle feedback device and the rotation center point of the rudder angle transmitter, the first angle deflection rod, the first connecting rod, the second connecting rod, and the second angle deflection rod form a parallelogram structure, as the rudder motor rotates, the rotation angles of the first angle deflection rod and the second angle deflection rod are consistent, which can eliminate the signal deviation phenomenon between the rudder angle feedback device and the rudder angle transmitter, thereby ensuring the navigation safety and control accuracy of the ship.

[0024] The present invention provides a ship, including a hull and a rudder angle signal feedback device as described above, which can eliminate the signal deviation between the rudder angle feedback device and the rudder angle transmitter, thereby ensuring the ship's navigation safety and control accuracy.

[0031] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0032] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0033] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0034] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0035] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0036] In order to eliminate the signal deviation between the rudder angle feedback device and the rudder angle transmitter, thereby ensuring the navigation safety and control precision of the ship, such as Figures 1-3 As shown, the present invention provides a rudder angle signal feedback device. The rudder angle signal feedback device includes a rudder angle transmitter 1, a rudder angle feedback device 2, a mounting assembly 5, a first connecting rod 3, and a second connecting rod.

[0037] The rudder angle transmitter 1 has a first angle deflection rod 11. The rudder angle transmitter 1 and the rudder angle feedback device 2 are located on opposite sides of the servo motor 100, and the rotation center points of the rudder angle transmitter 1, the rudder angle feedback device 2, and the servo motor rotation center point 110 of the servo motor 100 are on the same straight line. The rudder angle feedback device 2 has a second angle deflection rod 21. The mounting assembly 5 is mounted on the servo motor 100 and is located on the line connecting the servo motor rotation center point 110 and the zero angle line. One end of the first connecting rod 3 is rotatably connected to the mounting assembly 5, and the other end of the first connecting rod 3 is rotatably connected to the first angle deflection rod 11. One end of the second connecting rod 4 is rotatably connected to the mounting assembly 5, and the other end of the second connecting rod 4 is rotatably connected to the second angle deflection rod 21. The line connecting the rotation center point of the rudder angle feedback device 2 and the rotation center point of the rudder angle transmitter 1, the first angle deflection rod 11, the first connecting rod 3, the second connecting rod 4, and the second angle deflection rod 21 form a parallelogram structure.

[0038] During the rotation of the rudder 100, the mounting assembly 5 drives the first angle deflection rod 11 and the second angle deflection rod 21 to rotate via the first link 3 and the second link 4. The rudder angle transmitter 1 and the rudder angle feedback device 2 collect the corresponding rudder angle. Since the line connecting the rotation center point of the rudder angle feedback device 2 and the rotation center point of the rudder angle transmitter 1, the first angle deflection rod 11, the first link 3, the second link 4, and the second angle deflection rod 21 form a parallelogram structure, as the rudder 100 rotates, the rotation angles of the first angle deflection rod 11 and the second angle deflection rod 21 are consistent, which can eliminate the signal deviation phenomenon between the rudder angle feedback device 2 and the rudder angle transmitter 1, thereby ensuring the navigation safety and control accuracy of the ship.

[0039] In some embodiments, the mounting assembly 5 includes a mounting column 51 and a spacer 52. The mounting column 51 is mounted on the servo motor 100, and the spacer 52 is fitted onto the mounting column 51, with the spacer 52 positioned between the first link 3 and the second link 4. The mounting column 51 facilitates a rotatable connection with the first link 3 and the second link 4. The spacer 52 prevents contact between the first link 3 and the second link 4, thereby reducing friction and ensuring the flexibility of rotation of the first link 3 and the second link 4. To further enhance rotational flexibility, two bearings can be fixedly fitted onto the mounting column 51, with the first link 3 and the second link 4 engaging with the two bearings.

[0040] In some embodiments, the servo motor 100 has a threaded hole, and the lower end of the mounting column 51 has an external thread, with the mounting column 51 screwed into the threaded hole. By using a threaded hole and external thread to fix the mounting column 51, assembly is facilitated, and the positioning accuracy during the threading process is ensured, thus improving signal feedback accuracy after the column 51 is installed. In this embodiment, the threaded hole is located on the servo angle pointer 120 of the servo motor 100.

[0041] In some embodiments, the mounting assembly 5 further includes a locking member 53, which is disposed at the end of the mounting column 51 away from the servo motor 100. By providing the locking member 53, the axial position of the first link 3 and the second link 4 on the mounting column 51 can be restricted, preventing the first link 3 and the second link 4 from moving up and down axially on the mounting column 51, thereby ensuring the accuracy of the feedback rudder angle signal.

[0042] In some embodiments, the first connecting rod 3 includes a first rod portion 31, an intermediate rod portion 32, and a second rod portion 33 connected in sequence. The first rod portion 31 is rotatably connected to the mounting assembly 5, and the second rod portion 33 is rotatably connected to the first angle deflection rod 11. This arrangement facilitates the machining of eyelets at the ends of the first connecting rod 3 and the second connecting rod 4, and allows for direct replacement of the first rod portion 31 and the second rod portion 33 after wear. In other embodiments, the first connecting rod 3 can also be designed as an integrated structure, saving installation steps and improving assembly efficiency.

[0043] In some embodiments, the intermediate rod portion 32 has a first threaded hole and a second threaded hole at both ends. The first rod portion 31 has a first external thread, and the second rod portion 33 has a second external thread. The first rod portion 31 is connected to the first threaded hole via the first external thread, and the second rod portion 33 is connected to the second threaded hole via the second external thread. Assembling the first connecting rod 3 using a threaded connection facilitates installation and allows adjustment of the screwing depth of the first rod portion 31 and the first threaded hole, as well as the screwing depth of the second rod portion 33 and the second threaded hole, according to actual needs, thereby achieving the purpose of adjusting the length of the first connecting rod 3. In other embodiments, the first threaded hole can be provided on the first rod portion 31, the second threaded hole can be provided on the second rod portion 33, and the first and second external threads can be provided at both ends of the intermediate rod portion 32. Alternatively, external threads can be provided on the first rod portion 31, the intermediate rod portion 32, and the second rod portion 33, and nuts can be used to connect the first rod portion 31 and the intermediate rod portion 32, as well as the second rod portion 33 and the intermediate rod portion 32. No further limitations are imposed here. Similarly, the second link 4 can also adopt the segmented connection structure of the first link 3, which will not be elaborated on here.

[0044] In some embodiments, the first external thread and the second external thread have opposite directions of rotation. With the above configuration, during the assembly of the first connecting rod 3, only the intermediate rod portion 32 needs to be rotated to adjust the first rod portion 31 and the second rod portion 33 to move closer or further apart, thus enabling rapid adjustment of the length of the first connecting rod 3.

[0045] In some embodiments, the rudder angle signal feedback device further includes a first mounting base 6, on which the rudder angle transmitter 1 is mounted. By using the first mounting base 6, the rudder angle transmitter 1 can be effectively fixed and supported, thereby ensuring that the relative position of the rudder angle transmitter 1 on the hull remains unchanged and guaranteeing the accuracy of the rudder angle signal acquisition. To ensure a stable connection between the first mounting base 6 and the lower deck of the hull, a first reinforcing plate 61 is provided between the first mounting base 6 and the lower deck. One end of the first reinforcing plate 61 is connected to the first mounting base 6, and the other end of the first reinforcing plate 61 is connected to the lower deck.

[0046] In some embodiments, the rudder angle signal feedback device further includes a second mounting base 7, on which the rudder angle feedback device 2 is mounted. By providing the second mounting base 7, the rudder angle signal feedback device can be effectively fixed and supported, thereby ensuring that the relative position of the rudder angle signal feedback device on the hull remains unchanged and guaranteeing the accuracy of rudder angle signal acquisition. To ensure a stable connection between the second mounting base 7 and the hull structure, a second reinforcing plate 71 is provided between the second mounting base 7 and the hull structure. One end of the second reinforcing plate 71 is connected to the second mounting base 7, and the other end is connected to the hull structure.

[0047] This embodiment also provides a ship, which includes a hull and the rudder angle signal feedback device as described above. The rudder angle signal feedback device is installed in the hull and can eliminate the signal deviation between the rudder angle feedback device 2 and the rudder angle transmitter 1, thereby ensuring the navigation safety and control accuracy of the ship.

[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
