The same reference numbers in the drawings identify the same or similar elements or components. Those skilled in the art will appreciate that the drawings are not necessarily drawn to scale.

Referring to fig. 1, the utility model provides a boats and ships driving system of intelligent propulsion, location and anti-rolling, the output shaft of host computer 1 passes through

shaft coupling

In this example, 5 blades 12 are uniformly arranged around the central axis of the rotary box body in the circumferential direction, a blade shaft 16 is rigidly connected to the root of each blade 12, the blade shaft 16 is mounted in a mounting hole of the rotary box body 15 through a bearing, and the central line of the blade shaft 16 is parallel to the central axis of the rotary box body 15.

Referring to fig. 3, a regular pentagonal support is installed at the center of the rotary box body 15, each side of the support is provided with a hinge point, one end of the servo cylinder 14 is hinged with the support at the hinge point, a piston rod at the other end is fixedly connected with the connecting rod 11, and the connecting rod 11 is fixedly connected with the installation point of the blade shaft 16. The mounting point on the blade shaft 16 is offset from the position of the blade shaft centerline, thereby enabling the linear motion of the piston rod of the servo cylinder 14 to be translated into rotation of the blade 12 about the blade shaft centerline.

An integrated control valve group 13 is further mounted on a support in the rotary box body 15, an oil outlet of the integrated control valve group 13 is connected to an oil inlet of the servo cylinder 14 through a pipeline, and an oil inlet of the integrated control valve group 13 is connected with the hydraulic rotary joint 6 through a pipeline. Hydraulic pressure rotary joint 6 divide into rotating part and fixed part two parts, and the rotating part passes through rotary joint

The propeller base 8 is also provided with a hydraulic power unit 9 outside, which is communicated with the fixed part of the hydraulic rotary joint 6 through a pipeline to provide a power oil source for the system.

For rotating between rotatory box 15 and the propeller base 8 and being connected, propeller base 8 passes through the bolt fastening to hull base 10 on, 8 stationary propeller bases, rotatory box 15 around center pin rotary motion.

Referring to fig. 4 to 7, the present invention provides a method for operating a power system of a ship, which is capable of intelligently propelling, positioning and stabilizing, and for convenience of description, a straight line passing through the center of mass of a blade and perpendicular to the inner side of the blade is called as a center of mass perpendicular line.

The utility model makes the mass center vertical lines of all the blades 12 meet at a convergence point, and adjusts the magnitude and direction of the thrust generated by the ship power system by controlling the distance between the convergence point and the horizontal central line and the vertical central line of the rotating box body 15; for example: if the convergence point falls in the positive direction of the horizontal center line, a positive vehicle thrust (as shown in fig. 4) is generated, and if the convergence point falls in the negative direction of the horizontal center line, a reverse vehicle thrust (as shown in fig. 5) is generated; if the convergent point is in the positive direction of the vertical central line, a left thrust is generated (as shown in fig. 6); the convergence point is in the negative direction of the vertical centerline, producing a right thrust (as shown in fig. 7).

Referring to fig. 2, in the present example, two sets of ship power systems are installed on both sides of the stern portion or both sides of the bow portion of the ship, and the blades 12 are extended from the bottom of the ship and submerged in the water.

Referring to fig. 3, the angle of 5 blades 12 in the figure is the initial installation angle, i.e. the horizontal section center line of the blade is parallel to the circumferential tangential direction of the revolution, and in this state, the blades 12 revolve around the central axis along with the rotating box 15 without generating any thrust in any direction.

In the revolution process of the blades 12, the angles of the blades are in a constantly changing state, and the process is seen continuously, namely, the blades oscillate back and forth around the central line of the blade shaft while the blades 12 revolve around the central shaft along with the rotating box body 15. An angle sensor is arranged on the paddles 12, the positions of the paddles 12 in the revolution are fed back to the control system in real time, and meanwhile, a stroke sensor is arranged on the servo cylinder 14 to feed back the angle of each paddle 12. After receiving the feedback signal, the control system compares the feedback signal with the calculated value, analyzes the comparison result and sends an instruction signal to the integrated control valve group 13, and the integrated control valve group 13 controls the servo cylinder 14 to push the connecting rod 11 to correct the angle of the paddle 12. Each blade 12 is controlled by a separate servo cylinder 14, control accuracy and reliability can be guaranteed, and maintenance is easy.

In this example, the ship power system realizes stepless adjustment of the thrust direction and magnitude, in the state shown in fig. 6, the angles of the blades 12 follow a certain mathematical relationship, and the blades 12 always keep the mathematical relationship between the angles of the blades 12 unchanged in the revolution process, so that the blades can swing at the same speed, and the constant thrust direction is ensured. When this angular relationship is changed, the thrust direction is also changed.

The relationship between the angles of each blade 12 is: the vertical line which is vertical to the central line of the horizontal section of the blade through the stress point of the blade is converged at one point, and the point falls in the positive direction of the horizontal central line to generate the forward thrust; the point falls on the negative direction of the horizontal center line to generate backing thrust; the point is in the positive direction of the vertical central line to generate left thrust; this point falls in the negative direction of the vertical centerline, producing a right thrust. The control system is used for calculating the angle of each blade and controlling the position of the virtual control point, so that stepless adjustment of the thrust direction can be realized.

The magnitude of the thrust can be varied when the angular relationship between the blades 12 is unchanged, but only the value of the angle itself is varied.

The stepless adjustment of the thrust direction and magnitude is realized in the above manner, fig. 4 is one of the limit states of the present example, fig. 5, fig. 6 and fig. 7 respectively illustrate a reverse maximum thrust state, a left thrust maximum thrust state and a right thrust maximum thrust state in the operation process of the present example, the operation principle and the operation process are similar to the forward maximum thrust state shown in fig. 6, and no further description is provided here, and the difference is only that the angle relationship between the blades 12 is different. After the control system calculates the matching parameters of the positions and the angles of the extreme states, the matching parameters are preset to be functional modules of the states, and an operator only needs to select different state options to realize the functions of the control system.

In the embodiment, the ship power system can provide a propelling function and a positioning and stabilizing function, and the system controls the angle of the blades 12 in a hydraulic mode, so that stepless adjustment of the direction and the size of the thrust is achieved, for example, when sudden storms or torrents occur on the sea surface and the ship body needs to be positioned, the system can also adjust the size and the direction of the thrust quickly to resist, and therefore the positioning function is achieved.

Referring to fig. 8, preferably, an acceleration sensor is installed on the propeller base, and can sense the direction and angle of the ship hull rolling and feed back to the control system, and the control system sends out commands to control the angle change of the blades 12, so as to generate a stable moment resisting the rolling, thereby realizing the function of stabilizing the rolling. Because the system is active stabilization, the stabilization can be carried out no matter the ship is stopped, sailing or positioned, particularly, the sailing power of the ship is preferentially ensured in the sailing state of the ship, and the stabilization is carried out by utilizing extra effective power, namely, the full-speed stabilization is realized.

The utility model has the advantages that:

1. the angle of the paddle is controlled by hydraulic pressure, so that the direction and the magnitude of the thrust can be adjusted in a stepless manner, the rudder direction can be changed within a very short time, the time for switching from full-speed forward driving to full-speed reverse driving is only about 3 seconds, and the ship can rotate fully at 360 degrees in situ;

2. the functions of propulsion, positioning and stabilization are integrated, and the function modules are preset, so that the operation is convenient and simple;

3. each blade is controlled by an independent servo cylinder, so that the control precision is high, the reliability is high, and the maintenance is easy;

4. the paddle is forged by stainless alloy steel materials, is corrosion-resistant and high in strength, has a firmer structure and higher impact resistance, and can bear higher torque particularly at low working rotating speed;

5. the pressure distribution of the blades on the vertical chord length is uniform, even if part of the blades are exposed out of the water surface, the thrust can be provided, the normal operation of the ship is maintained, and the reduction of the thrust is gentle along with the increase of the exposed area of the blades.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
