Description

Technical Field

[0001] This invention belongs to the field of ship maneuvering and control system technology, and more specifically, relates to a modular ship maneuvering and control system and its usage method. Background Technology

[0002] With the development of maritime and marine technology, ships are equipped with a wide variety of propellers. The ship's steering controller has become an indispensable control component for these propellers. By controlling the speed of the propellers forward and backward using the controller's lever, or by adjusting the direction of the propellers through circumferential rotation of the controller's lever, the ship's speed and direction are ultimately controlled. Steering controllers generally have two uses: one is to adjust speed during main thrust or side thrust, and the other is to adjust speed and direction simultaneously during a full azimuth. The structural forms of the steering controllers corresponding to these two functions differ.

[0003] For control systems that only require speed adjustment, such controllers are mainly used in propulsion control systems. The control is further divided into individual control and synchronous control. The propulsion control system will equip each main engine or side thruster with a control controller. For control systems that require both speed and direction adjustment, such controllers are mainly used in azimuth propulsion systems. In terms of structural layout, speed adjustment is integrated into direction adjustment.

[0004] Currently, the existing control controllers have some problems. The existing speed control controllers have the following issues: (1) increasing the number of control controllers on the cab control panel. (2) in cases with dual main engines, the controllers are arranged separately, making it impossible to intuitively compare the commands given by the main engines. (3) if it is necessary to adjust the speed of the dual main engines synchronously, the requirements for the helmsman are very high, and it is very easy to cause the main engine speeds to be out of sync or to cause misoperation.

[0005] Existing control controllers for adjusting speed and direction: (1) Existing control controllers use a gear and rack composite structure, and the rack is designed as a cylindrical distribution structure, which requires high processing and manufacturing. (2) In direction adjustment, the zero position, quadrant position and damping are all inside the controller, which can only be adjusted before leaving the factory. They cannot be adjusted during use and cannot meet the actual use requirements. (3) In speed adjustment, the electrical wiring has a problem of tangling during rotation. Summary of the Invention

[0006] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a modular ship maneuvering control system, characterized by comprising: a speed module, a direction module, a single-lever control controller composed of a single speed module and a control stick, a dual-lever control controller, and a full-rotation control controller assembled from the single-lever control controller and the direction module; wherein,

[0007] The single-lever control controller includes a first speed housing, a single control lever located on the top of the single-lever control controller for controlling speed propulsion, a first end cap located at the right end of the single-lever control controller, a first base for fixing the single-lever control controller, and a speed module fixed by the first speed housing.

[0008] The dual-lever control controller is assembled from the single-lever control controller and also includes a first dual-lever, a second dual-lever, and a locking member disposed on the second dual-lever. The first dual-lever and the second dual-lever are symmetrically arranged and can respectively give speed signals to the two speed modules.

[0009] The full-rotation control controller is composed of modules, including a single-lever control controller, a direction module, a square panel, a transition piece, and an outer cover. One end of the transition piece is fixedly connected to the connection hole reserved in the first base by bolts, and the other end is connected to the hollow shaft and fixed to the square panel by bearing clamps. The direction module is installed on the square panel to form a speed signal given by the control lever. The speed module rotates as a whole to adjust the direction of the thruster.

[0010] Furthermore, the speed module includes an outer plate, studs, an inner plate, a potentiometer, a potentiometer gear, a zero-position component, a speed shaft, a damping component, and a speed gear X; the outer plate is fixedly connected to the inner plate as a whole by studs, the potentiometer is fixed on the inner plate, and the potentiometer gear located at the right end of the potentiometer meshes with the speed gear X.

[0011] Furthermore, the zero-position component includes a zero-position wheel, a zero-position seat, a first adjusting screw, a spring, an adjusting block, a pin, and a roller.

[0012] Furthermore, one end of the zero-position seat is fixed to the inner plate, and the other end is engaged with the zero-position wheel, which is fixed to the zero-position wheel on the speed shaft of the speed module.

[0013] Furthermore, the damping component includes an anti-rotation stud, a clamping body, and a second adjusting screw, with the clamping body passing through the speed shaft of the speed module.

[0014] Furthermore, the anti-rotation stud is hexagonal, which fits perfectly inside the circular hollow core, and the anti-rotation function is achieved through the anti-rotation edges.

[0015] Furthermore, the locking component is characterized by comprising a locking pin, a positioning pin, and a compression spring. When the dual-lever control controller needs to adjust the speed synchronously, the locking component extends out and is inserted into the pre-drilled hole of the first dual-lever control to achieve synchronous control.

[0016] Furthermore, the directional module is characterized by comprising a hollow shaft, an encoder component, an upper plate, a lower plate, a mounting post, and a directional gear.

[0017] Furthermore, the direction module also includes a photoelectric slip ring, a second locking ring, and a tightening screw. The moving end of the photoelectric slip ring is fixed by the tightening screw and the hollow shaft, and the stationary end of the photoelectric slip ring is fixed to the lower plate of the direction module by the screw, so as to avoid the speed module potentiometer wires from getting tangled during rotation.

[0018] A method for using a modular ship maneuvering control system includes the following steps:

[0019] S100: Assemble the corresponding control unit in advance as needed;

[0020] S200: Install the control controller on the control system console and connect the encoder wiring to the system through the hollow base;

[0021] S300: In single-lever mode, the speed can be adjusted by pushing a single control lever;

[0022] S400: In dual-lever mode, when controlled individually, the first and second dual-lever control levers are controlled separately to give different speed control commands. When controlled synchronously, the locking member extends to connect the two levers into a whole. By pushing the connected levers, the speed can be adjusted and the speed of the thruster can always be kept synchronously changed.

[0023] S500: In the full rotation state, when a thruster speed signal is given, the thruster speed can be adjusted by pushing the control lever on the single-lever control controller. When a direction signal is required, the entire top of the control controller is rotated, which drives the rotation shaft and thus the direction module to work, thereby adjusting the direction of the thruster. Overall, compared with the prior art, the above technical solution conceived by this invention can achieve the following beneficial effects:

[0024] 1. The present invention provides a modular ship maneuvering control system and its usage method, which combines and assembles a speed module and a direction module to form a maneuvering controller, making the product layout more compact and reasonable, and this technical solution is more conducive to production, processing, installation, debugging and maintenance.

[0025] 2. The present invention provides a modular ship maneuvering control system and its usage method. By adding a locking component through partial modification of the dual-lever control controller, it is possible to quickly and conveniently switch between individual control and synchronous control modes. The locking component connects the two control levers, ensuring that the speed commands given by the left and right control levers are exactly the same in synchronous control mode, resulting in good synchronization performance.

[0026] 3. The modular ship maneuvering control system and its usage method of the present invention effectively avoid the problem of speed signal lines tangling above the azimuth control controller by designing the shaft as a hollow shaft and using a cap-type photoelectric slip ring, thereby extending the service life of the product.

[0027] 4. The present invention provides a modular ship maneuvering control system and its usage method. After prolonged use, the damping and zero-position wear of the full-turn maneuvering controller will change the feel of the maneuvering. The present invention can restore the maneuvering feel by adjusting the damping and zero position, thus meeting the operator's usage habits. Attached Figure Description

[0048] Depend on Figures 1-10 This invention discloses a modular ship maneuvering control system, comprising: a single-lever control controller 1, a dual-lever control controller 2, and a full-rotation control controller 3. The three controllers are used in different operating modes. The dual-lever control controller 2 is used in a dual-engine configuration to adjust speed. In individual control mode, speed commands are given by advancing the left and right control levers. In synchronous control mode, the two control levers are connected by a locking mechanism to ensure identical speed commands. This achieves both individual and synchronous control through partial operation, reducing operational difficulty and the possibility of misoperation. The full-rotation control controller 3 is used to adjust speed and direction, using a transition mechanism to achieve these adjustments. The single-lever control controller 1 can be quickly expanded into a dual-lever control controller 2 by adding a speed module and replacing the control lever. The single-lever control controller 1 can also be assembled into a full-rotation controller by adding a transition mechanism, a square panel, and a direction module.

[0049] Depend on Figure 1 As can be seen, the single-lever control controller 1 includes: a first speed housing 11, a single joystick 12 located on the top of the single-lever control controller 1 for controlling speed propulsion, a first end cap 13 located at the right end of the single-lever control controller 1, a first base 14 for fixing the single-lever control controller 1, and a speed module 4 fixed by the first speed housing 11. The single-lever control controller 1 has a speed module 4, with both ends of the speed module 4 connected by the single joystick 12, and the lower side fixed to the first base 14. The three components are connected to the empty space at the other end, forming a whole in appearance. The first base 14 is hollow, which facilitates the signal wire to pass through the middle.

[0050] In this embodiment, the single-lever control controller 1 is used as follows: First, the encoder installed on the control console system and then protruding from the hollow hole in the first base 14 is connected to the control system. Then, by pushing the single lever 12 forward, the gear on the rotating shaft and the encoder output are driven, thereby achieving the purpose of adjusting the speed of the thruster.

[0051] Depend on Figure 2It is understood that the dual-lever controller 2 includes: a second speed housing 21, a first dual-lever 22, a second dual-lever 23, second end caps 24 located at both ends of the speed modules, a locking member 25, and a second base 26 for fixing the dual-lever controller 2. The dual-lever controller 2 has two speed adjustment modules. The levers are in a split form, allowing control commands to be given to the speed modules separately. The first dual-lever 22 on the left and the second dual-lever 23 on the right are symmetrically arranged. The locking member 25 is located on the second dual-lever 23. When synchronous control is required, the first dual-lever 22 and the second dual-lever 23 are connected into a whole through the locking member 25 to achieve the effect of synchronously controlling the two speed modules 4.

[0052] In this embodiment, the dual-lever control controller 2 is used as follows: First, the encoder installed on the control console system and then protruding from the hollow hole in the second base 26 is connected to the control system. When different speeds of the thruster are required, i.e., individual control, the first dual-lever 22 and the second dual-lever 23 are controlled to give different speed control commands. When the thruster speed is required to be the same and can be synchronously adjusted, i.e., synchronous control, the locking member 25 located at the lower end of the second dual-lever 23 is pushed out to connect the two levers into a whole. By pushing the connected levers, the speed is adjusted and the speed of the thruster is always kept synchronously changing.

[0053] Depend on Figure 3 It is understood that the locking component 25 includes: a locking pin 251, a positioning pin 252, and a compression spring 253. The locking pin 251 is disposed inside the second double control lever 23, the compression spring 253 is sleeved on the end of the locking pin 251, and the positioning pin 252 is arranged perpendicularly to the locking pin 251. When the double control lever 2 needs to be adjusted or controlled synchronously, the positioning pin 252 causes the locking pin 251 to slide and be positioned in the groove of the second double control lever 23, and the locking pin 251 is extended and inserted into the reserved hole on the end face of the first double control lever 22, so that the first double control lever 22 and the second double control lever 23 are fixedly connected, reducing the difficulty for the operator to perform synchronous adjustment and avoiding the probability of misoperation.

[0054] Depend on Figure 4It is known that the full-rotation control controller 3 includes: a single-lever control controller 1, a speed module 4, a direction module 5, a square panel 31, a transition piece 32 connecting the single-lever control controller 1 and the direction module 5, and an outer cover 33. The full-rotation control controller 3 is composed of modules. Based on the single-lever control controller 1, a transition piece 32 is added to connect the direction module 5. When direction adjustment is required, the speed module 4 is rotated into the direction module 5 through the transition piece 32 to realize the input of direction adjustment. One end of the transition piece 32 is fixedly connected to the connection hole reserved in the first base 14 by bolts, and the other end is connected to the hollow shaft and fixed to the square panel 31 by bearing clamps. The direction module 5 is installed on the square panel 31 and the outer cover 33, thus forming a control lever to adjust the speed, and the speed module 4 rotates as a whole to adjust the direction of the thruster.

[0055] In this embodiment, the azimuth control controller 3 is used as follows: The azimuth control controller 3 is assembled modularly and fixedly connected to the control system console. The control system is then connected to the signal terminal on the azimuth control controller 3. When a thruster speed signal is required to operate the azimuth control controller 3, the thruster speed can be adjusted by pushing the control lever on the single-lever control controller 1. When a direction signal is required, the entire top of the control controller is rotated, which drives the rotation shaft, thereby activating the direction module 5 to adjust the thruster's direction.

[0056] Depend on Figure 5 It is known that the transition piece 32 includes: a connecting hole 321, a hollow shaft mounting hole 322, and a fixing slot 323. The connecting hole 321 is fixedly connected to the first base 14 by bolts, connecting the transition piece 32, the speed module 4, and the direction module 5 into a whole, which facilitates the adjustment of the direction module by the full-rotation control controller 3. The hollow shaft mounting hole 322 is pre-drilled and fixedly connected to the hollow shaft in the direction module 5 by bolts. The fixing slot 323 is engaged with the bearing to achieve effective connection.

[0057] Depend on Figure 6-8As can be seen, the speed module 4 includes an outer plate 41, a stud 42, an inner plate 43, a potentiometer 44, a potentiometer gear 45, a first locking ring 46, a zero-position component 47, a speed shaft 48, a damping component 49, and a speed gear 4X. The outer plate 41 is located on the outside of the speed module 4 and is connected to the inner plate 43 located on the inside of the speed module 4 via the stud 42. One end of the stud 42 is connected to the inner plate 43, and the other end is connected to the outer plate 41, forming a whole. The speed shaft 48 is fixed to the outer plate 41 and the inner plate 43 by bearings. The left side of the speed shaft 48 is provided with a zero-position component 47 and a first locking ring 46. The right side of the first locking ring 46 is equipped with a speed gear 4X. The right side of the speed gear 4X is equipped with a damping component 49. The potentiometer 44 is fixed to the upper inner plate 43, and the shaft-end potentiometer gear 45 meshes with the speed gear 4X.

[0058] The zero-position component 47 includes a zero-position wheel 471, a zero-position seat 472, a first adjusting screw 473, a spring 474, an adjusting block 475, a pin 476, and a roller 477. One end of the zero-position seat 472 is fixed to the inner plate 43, and the other end is engaged with the zero-position wheel 474. The zero-position wheel 474 is fixed to the speed shaft 48 of the speed module. The pin 474, adjusting block 475, and roller 477 connect the zero-position wheel 471 and the zero-position seat 472. The pin 474, adjusting block 475, and roller 477 are fixed together to form a whole. A spring 473 is provided on the right side of the adjusting block 475. The spring 473 can be used to drive the adjusting block 475, thereby driving the zero-position wheel 471. As the zero-position wheel 471 rotates, it engages in the corresponding position. The first adjusting screw 473 is located on the right side of the spring. By adjusting the first adjusting screw 473, the pressure of the spring is changed, thereby realizing the rotation of the zero-position wheel 471. The zero-position function is achieved by the ball bearing moving up and down in the groove of the zero-position disk and the zero-position component 57 in the direction module 5 under the action of elastic force.

[0059] The damping component 49 includes an anti-rotation stud 491, a clamping body 492, and a second adjusting screw 493. The clamping body 492 passes through the speed shaft 48 of the speed module. The anti-rotation stud 491 is located on the upper part of the damping component 49 and is fixed to the outer plate 41 of the speed module 4. It achieves anti-rotation through its anti-rotation angles. In this embodiment, the anti-rotation stud 491 is hexagonal, fitting perfectly inside the circular hollow core. The second adjusting screw 493 is located at the lower end of the damping component 49, perpendicular to and penetrating the clamping body 492. The end face of the screw is in close contact with the clamping body 492. The damping magnitude is adjusted by the second adjusting screw 493. The damping function is achieved by adjusting the tightness of the clamping body 492 through the second adjusting screw 493 and the rotation shaft at the lower end of the transition piece 32, thereby adjusting the damping of the direction module 5.

[0060] Depend on Figure 9-10It can be seen that the direction module 5 includes: hollow shaft 51, encoder component 52, upper plate 53, lower plate 54, photoelectric slip ring 55, second locking ring 56, mounting post 57, direction gear 58, and tightening screw 59. The hollow shaft 51 is located at the center of the direction module 5. The shaft is hollow inside and is fixed by the upper plate 53. The lower end has a second locking ring 56 and a tightening screw 59 on both sides. The bottom end face is fixed to the moving end of the photoelectric slip ring 55 by the tightening screw 59. The stationary end of the photoelectric slip ring 55 is fixed to the lower plate 54 of the direction module by the screw, so as to avoid the speed module potentiometer wires from getting tangled during rotation and increasing the maintenance difficulty. The upper plate 53 is fixed to the square panel 31 by the mounting post 57, and the lower plate 54 is fixed to the upper plate 53 by the mounting post 57. The damping module 49 in the direction module 5 is equipped with a direction gear 58. When the full rotation control controller 3 needs to give a direction adjustment command, the direction gear 58 drives the whole to rotate. The encoder component 52 is located at the left end of the direction gear 58. The encoder component includes an encoder and an encoder gear. The encoder is installed on the upper plate 53, and the encoder gear meshes with the direction gear 58.

A method of using a modular ship maneuvering control system as described in any one of claims 1-9, characterized in that, Includes the following steps: S100: Assemble the corresponding control unit in advance as needed; S200: Install the control controller on the control system console and connect the encoder wiring to the system through the hollow base; S300: In single-lever mode, the speed can be adjusted by pushing a single control lever; S400: In dual-lever state, when controlled individually, the first dual-lever (22) and the second dual-lever (23) are controlled to give different speed control commands. When controlled synchronously, the locking member is extended to connect the two levers into a whole. By pushing the connected levers, the speed is adjusted and the speed of the thruster is kept synchronously. S500: In the full rotation state, when a thruster speed signal is required, the thruster speed can be adjusted by pushing the lever on the single lever control controller (1). When a direction signal is required, the entire upper part of the control controller is rotated, which drives the rotation shaft at the lower end of the transition piece (32) to drive the direction module (5) to work, thereby adjusting the direction of the thruster.
