JP3080422U - Automatic countercurrent type ship combined with optimal operating device - Google Patents

Abstract

(57) [Summary] [PROBLEMS] An automatic countercurrent type ship having excellent advantages such as less shaking and overturning danger has an advantage that it can immediately turn in any direction in any direction of 360 degrees and move forward. However, conventional steering devices are not adequate to cope with this sudden turn. SOLUTION: The present invention collects radial legs 7 of an automatic countercurrent ship in order to make full use of its excellent mobility by combining a maneuvering device considered to be optimal for an automatic countercurrent ship. A girder 3 is horizontally fixed to the upper end of a rotatable shaft 4 vertically penetrating the center portion, and a propeller 1 for propulsion is provided at one end of the girder 3 and a propeller 2 for correcting the direction is provided at the other end.
Is installed. The rotatable shaft 4 penetrates through the ceiling of the cabin 5 and hangs down in the cabin 5, and a pilot seat 6 is fixed to the lower end of the rotatable shaft 4 so that the propeller 2 for direction correction can be seen from the front. . The operator rotates the direction correcting propeller 2 forward or backward while comparing it with the target direction,
The direction of propulsion of the propelling propeller 1, that is, the direction of travel of the automatic countercurrent ship, is immediately and easily and accurately directed to the target direction.

[Prior art]

 Automatic countercurrent vessels have the advantages of having less danger of unpleasant swaying and capsizing that may cause seasickness, but they also have the advantage of being able to turn immediately and move forward in any direction at 360 degrees. However, conventional operating devices are not adequate to cope with such a sudden turn.

[0003]

[Problems to be solved by the invention]

 The present invention solves such operational problems and contributes to the practical use of automatic countercurrent vessels.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a girder is fixed horizontally to the upper end of a rotatable shaft that penetrates vertically through the central part of the radial legs of an automatic countercurrent ship, and a propeller for direction correction is attached to one end of the girder. The propeller is mounted on the other end of the girder, and the operator's seat is fixed to the lower end of the rotatable shaft so that the propeller for direction correction can be seen from the front.

[0005]

[Action]

 The operator turns the propeller for forward direction forward and backward by rotating the propeller for direction correction forward and backward while comparing the propeller for direction correction looking up to the front direction, thereby making the direction of travel of the automatic countercurrent ship by the propeller for propeller 360 degrees. In any direction you can always control it quickly and easily.

【Example】

 At the lower end of four long legs 7 radially attached with the cabin 5 as the center, a flexible bag-shaped floating body 8 (in the case of a model ship, a balloon may be used) or, as shown in FIG. 7 has a floating body 8 rotatably attached to the lower end thereof. The latter will not be described in detail because the present inventor has applied for a patent before, but it is possible to further enhance the automatic countercurrent performance by fixing the floating body stretching plate 9 to the rear part of the floating body 8. When the ship reciprocates on land and on the water via the ramp way, a caster (not shown) may be attached to the lower end of the leg 7 and used together. Such a floating body 8 has a property of automatically turning in the direction of the water flow due to the movement of the ship or the waves or tides so as to adapt to the flow due to the resistance of the water. As an optimal operating device to be combined with an automatic countercurrent ship having such properties, a girder 3 is horizontally fixed to an upper end of a rotatable shaft 4 vertically penetrating a central portion where the legs 7 are gathered. The propulsion propeller 1 is mounted on one end of the beam 3 and the direction correcting propeller 2 is mounted on the other end. The rotatable shaft 4 penetrates through the ceiling of the cabin 5 and hangs in the cabin 5, and a pilot seat 6 is fixed to the lower end of the rotatable shaft 4 so that the propeller 2 for direction correction can be seen from the front. . However, the operator's seat 6 is not suspended, but is equipped with casters (not shown) at the lower portion, so that it can rotate freely while supporting the weight on the floor of the cabin 5. I have. Therefore, the operator always rotates the direction correcting propeller 2 forward or backward while looking up the direction correcting propeller 2 while comparing it with the target direction, thereby changing the propulsion direction of the propulsion propeller 1, that is, the automatic direction. The direction of the watercraft can always be easily and accurately directed to the desired direction.

[Effect of the invention]

 By combining the maneuvering device according to the present invention, the outstanding mobility of an automatic countercurrent ship can be instantaneously and fully exerted, and in combination with the stability of the automatic countercurrent ship on water with severe winds, fishing boats It is suitable for a wide range of uses such as rescue boats, guard boats, escort ships, sport boats, fishing boats, and so on. The largest living thing on the water is the water strider, whose form, refined over the course of its evolution over the years, is ideal for water life. Given the state-of-the-art aircraft and space shuttle formally resemble birds, nuclear submarines resemble fish, and 4WD resemble dogs, this suggests that surface ships should adopt a form resembling water striders. It can be said that there is.

Claims (1)

[Utility model registration claims] At each lower end of a radial leg, a floating body which automatically changes its direction in the direction of a water flow generated by a ship or a wave or a tidal current by a resistance of water is provided. The girder is fixed horizontally on the upper end of a rotatable shaft that penetrates the shaft, a propeller for propulsion is mounted on one end of the girder, a propeller for direction correction is mounted on the other end, and the direction of the driver's seat is corrected on the lower end of the shaft. Automatic counter-current ship characterized in that the propeller is fixed so that it can be seen from the front.
