Abstract
Description
- The present invention relates to a technique regarding a vessel.
- Conventionally, a technique of an Arneson Surface Drive for a vessel is known. The Arneson Surface Drive is a drive system that drives a propeller by a propeller shaft via a universal joint and controls the vertical and horizontal directions of the propeller by a hydraulic cylinder (for example, Patent Document 1).
- In addition, a vessel is known in which only two right and left Arneson Surface Drives are disposed and propellers are controlled in the horizontal direction to steer the vessel. In such a vessel, right and left propellers are interlockingly controlled to steer the vessel. However, no vessel is disclosed which includes Arneson Surface Drives whose right and left propellers are controlled independently of each other in order to obtain propulsive force in an arbitrary direction.
- Patent Document 1:
JP H06-92286 A - An object of the present invention is to provide a vessel capable of obtaining propulsive force in an arbitrary direction.
- A vessel according to the present invention includes an Arneson Surface Drive which drives a propeller by a propeller shaft via a universal joint and which controls the propeller in a horizontal direction by a hydraulic cylinder. It is preferable that the vessel includes only two Arneson Surface Drives which are disposed on the right and left of a hull, and the propellers are controlled in the horizontal direction independently of each other.
- In the vessel according to the present invention, when there is an abnormality in the hydraulic cylinder, control is performed such that a current slidable region of the hydraulic cylinder is set as entirety of a subsequent slidable region.
- With the vessel according to the present invention, it is possible to obtain propulsive force in an arbitrary direction.

Fig. 1 is a schematic diagram showing a configuration of a vessel. -
Fig. 2 is a schematic diagram showing an effect of the vessel. -
Fig. 3 is a schematic diagram showing another effect of the vessel. - The configuration of a
vessel 100 will be described with reference toFig. 1 . - In
Fig. 1 , for the sake of easy understanding, ahull 10 is illustrated in a see-through manner. In the following description, front-back and right-left directions are determined assuming that a bow of thevessel 100 is a front of the vessel. - The
vessel 100 is an embodiment regarding a vessel according to the present invention. Thevessel 100 according to the present embodiment is a vessel with a twin-screw propulsion system including only two Arneson Surface Drives 40. Thevessel 100 includes thehull 10, twoengines 20, twoswitching clutches 30, the two Arneson Surface Drives 40, and a vessel steering device S. - The
engine 20 rotates apropeller 44 provided on the port side or the starboard side. Theengine 20 is disposed on each of the rear port side and the rear starboard side of thehull 10. The switchingclutch 30 is connected to an output shaft of eachengine 20. - The
engine 20 is provided with an engine control unit (hereinafter referred to as ECU) 52. The ECU 52 comprehensively controls theengine 20. The ECU 52 is connected to acontroller 50 to be described later. - The switching
clutch 30 outputs power transmitted from the output shaft of theengine 20 such that the rotation direction is switched over between a normal rotation direction and a reverse rotation direction. The output shaft of theengine 20 is connected to an input side of theswitching clutch 30. Apropeller shaft 41 is connected to an output side of theswitching clutch 30. - The operation of the switching
clutch 30 is controlled by ahydraulic circuit 53. Thehydraulic circuit 53 is provided with a plurality of solenoid valves (not shown) for performing circuit switchover or direction control. The solenoid valves are connected to thecontroller 50 to be described later. - The Arneson Surface Drive 40 is a drive system that drives the
propeller 44 by thepropeller shaft 41 via theuniversal joint 42 and controls the vertical and horizontal directions of the propeller by thehydraulic cylinder 43. - The
propeller 44 generates thrust in the front-back direction. Thepropeller 44 is connected to thepropeller shaft 41. Thepropeller 44 is rotationally driven by power of theengine 20 transmitted via thepropeller shaft 41. A plurality of blades is disposed around the rotation axis of thepropeller 44. The blades generate thrust by pushing water around the blades down and backwards. - The
propeller shaft 41 transmits power of theengine 20 to thepropeller 44. Thepropeller shaft 41 is provided so as to penetrate thehull 10 and reach the outside of the vessel. - The
universal joint 42 is provided in the middle of thepropeller shaft 41. Thepropeller shaft 41 is pivotally supported such that the propeller shaft can pivot around theuniversal joint 42 in the horizontal direction. - The
hydraulic cylinder 43 causes thepropeller 44 and thepropeller shaft 41 on a distal end side with respect to theuniversal joint 42 to pivot around theuniversal joint 42 in the horizontal direction. A base end of thehydraulic cylinder 43 is pivotally supported on a rear end of thehull 10. A distal end of thehydraulic cylinder 43 is pivotally supported on thepropeller shaft 41 on the distal end side with respect to theuniversal joint 42. - Operation of the
hydraulic cylinder 43 is controlled by ahydraulic circuit 51. Thehydraulic circuit 51 is provided with a plurality of solenoid valves (not shown) for performing circuit switchover or direction control. The solenoid valves are connected to thecontroller 50 to be described later. - The vessel steering device S includes the
controller 50 as a control means, thehydraulic circuit 51, theECU 52, thehydraulic circuit 53, ajoystick lever 54, anaccelerator lever 55, and asteering wheel 56. - The
controller 50 comprehensively controls thevessel 100. Thehydraulic circuit 51, theECU 52, thehydraulic circuit 53, thejoystick lever 54, theaccelerator lever 55, and thesteering wheel 56 are connected to thecontroller 50. - The
controller 50 has a function of continuing subsequent control (steering control in abnormality) by setting a current slidable region of thehydraulic cylinder 43 as 100% of a slidable region when there is an abnormality in thehydraulic cylinder 43. - More specifically, in the steering control in abnormality, when a piston (not shown) of the
hydraulic cylinder 43 stops halfway and cannot move to a target position, steering control is continued such that the region up to the location where the piston stops is set as a new slidable region. With such a configuration, even if the piston cannot move to the target position due to some cause, steering control can be continued. - Furthermore, in the steering control in abnormality, when the distance (piston sliding distance) from one end to the other end of the slidable region is smaller than a predetermined value, steering control can be stopped. With such a configuration, it is possible to prevent temperature rise of hydraulic fluid caused by an increase in pressure of the hydraulic fluid.
- The
joystick lever 54 generates a signal for moving thevessel 100 in an arbitrary direction. Thejoystick lever 54 is configured to be inclined at an arbitrary angle in an arbitrary direction. Thejoystick lever 54 is configured to generate a signal regarding rotational speed of theengine 20 and the switchover state of the switchingclutch 30 according to an operation mode and an operation amount. - The
accelerator lever 55 generates signals regarding rotation speed of thepropeller 44 on the port side, the rotation speed of thepropeller 44 on the starboard side, and rotation directions of thepropellers 44. Theaccelerator lever 55 is configured of a lever corresponding to thepropeller 44 on the port side and a lever corresponding to thepropeller 44 on the starboard side. - An effect of the
vessel 100 will be described with reference toFig. 2 . - In
Fig. 2 , the effect of thevessel 100 is schematically shown in plan view. - According to the
vessel 100, it is possible to obtain propulsive force in an arbitrary direction. According to thevessel 100, for example, propulsive force can be obtained in a diagonally left direction. At that time, thecontroller 50 controls both thehydraulic cylinders 43 such that thepropellers 44 of both the Arneson Surface Drives 40 are directed left rearward, and causes both thepropellers 44 to normally rotate so that thevessel 100 moves forward (a white arrow inFig. 2 ). - The effect of the
vessel 100 will be described with reference toFig. 3 . - Note that in
Fig. 3 , the effect of thevessel 100 is schematically shown in plan view. - According to the
vessel 100, it is possible to obtain propulsive force in an arbitrary direction. According to thevessel 100, for example, propulsive force toward the right can be obtained. At that time, thecontroller 50 controls thehydraulic cylinder 43 such that thepropeller 44 of the leftArneson Surface Drive 40 is directed left rearward, and causes thepropeller 44 to reversely rotate so that thevessel 100 moves backward (a white arrow inFig. 3 ). - At the same time, the
controller 50 controls thehydraulic cylinder 43 such that thepropeller 44 of the rightArneson Surface Drive 40 is directed right rearward, and causes thepropeller 44 to normally rotate so that thevessel 100 moves forward (a white arrow inFIG. 3 ). In this way, by generating different moments around the center of gravity of thehull 10, propulsive force toward the right can be obtained. - The present invention is applicable to a vessel.
