Description

[Detailed description of the device]

[Industrial applications]

 The present invention relates to a variable water-draining boat that can easily navigate in shallow water depths and can navigate comfortably at high speed in deep hydrophilic waters.

[0002]

[Prior art]

 Rivers, lakes and marshes and bays have extremely shallow and deep water. In order to navigate in such a place, if the shape of the ship is flat and the bottom of the ship is flat, shallow water can be obtained.However, since such a ship has a large propulsion resistance, it cannot travel at high speed and consumes fuel. There is also the problem of being large.

As a means for solving these problems, a central hull and a pair of left and right parts are arranged along both sides of the central hull, and the front and rear end upper parts are composed of a front end connecting part and a rear end connecting part. It has an external hull connected to it, and this external hull encloses a center part of the hull in a substantially rectangular shape. 2. Description of the Related Art There is known a variable watering boat which is provided with an up-and-down moving means composed of a guide and a hydraulic cylinder, and an outer hull is supported so as to be vertically movable with respect to a central hull (JP-A-1-289793).

When navigating in a shallow water area, this variable watering boat raises the outer hull to the maximum so that the bottom of the hull matches the bottom of the central hull, and in deep water, the outer hull is Is lowered to lift the center hull.

[0005]

[Problems to be solved by the device]

 When a ship goes out into the open sea, the hull will sway due to various waves, but the hull of the conventional variable-draining watercraft described above was prone to sway. In addition, when the space above the water surface is narrow due to a bridge, etc., it was sometimes obstructed by the upper part of the ship and it was not possible to pass there.

The present invention solves the above-mentioned problems, and in addition to being capable of navigating in shallow water depths, it is also capable of navigating at high speeds in deep water depths, less hulling of the hull due to waves, and bridges, etc. The purpose is to provide a variable water-draining boat that can forcibly reduce the height of the hull when passing through.

[0007]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and is composed of a main hull and a pair of floats arranged on both sides of the main hull, and both ends of the main hull and each float are pivotally attached to the hull. It is connected by at least two sets of connecting bodies consisting of an arm and a cylinder that can rotate in a direction perpendicular to the longitudinal direction, and is configured so that each float can be moved up and down by expansion and contraction of the cylinder. All of them have achieved such an objective by the variable water-draining boat, which is characterized in that the main engine for propelling the boat is installed inside.

[0008] In the above-mentioned variable water-draining boat, it is preferable that the float has a length substantially the same as or slightly shorter than that of the main hull, and one set of connecting bodies is near the bow of the main hull and the other is near the stern. It is preferable to attach it to.

As the cylinder, a cylinder capable of positive or negative pressure is used. This cylinder may be operated by fluid pressure such as hydraulic pressure or water pressure, and may be electrically operated. The cylinders may be operated at the same time, but it is preferable that the cylinders operate independently on each port side, and it is also possible that the cylinders operate individually. It is preferable to specify a mechanism for detecting the load and a load for each cylinder, and to provide a mechanism capable of maintaining this load.

[0010]

[Action]

 When the cylinder is extended, the float is pushed away from the main hull and the main hull rises. When the cylinder is contracted, the float is pulled toward the main hull side and the main hull descends. When making shallow water, it is controlled so that the load on the cylinder is minimized, although it depends on the design of the ship, etc. Rolling of the ship can be reduced by operating the cylinders independently on each side to control the load of the cylinder to be constant. By operating the cylinders individually and controlling the load on each cylinder to be constant, it is possible to reduce various types of ship sway.

The main engine for propelling the ship is installed in the float so that the thrust can be secured even when the main hull is located on the water.

[0012]

【Example】

 1 and 2 show a variable stuttering ship which is an embodiment of the present invention. This ship consists of a main hull 1 which is normally hull-shaped and a pair of floats 2 arranged on both sides of the main hull.

A steering room 3 is provided at the bow of the main hull 1, and a passenger compartment 4 is provided at the center. The ceiling 5 of the passenger compartment 4 can be raised and lowered, and can be temporarily lowered when necessary when passing a bridge or the like. There are seats 6 on the decks in the front and back of the cabin. A mast 7 is erected on the ship, but each mast can be bent. When passing through a bridge, etc., the mast should be tilted forward or backward or left or right as necessary.

A main engine 8 for propelling the ship is installed inside each float 2, and a propeller 9 and a rudder 10 rotated by the main engine 8 are attached to the tail of the float 2, respectively. Each float 2 has a watertight structure as a whole.

The main hull 1 and each float 2 are connected by three sets of connecting bodies each including an arm 11 and a hydraulic cylinder 12. One end of each arm 11 and the cylinder 12 are pivotally attached to the main hull 1 at one end and the float 2 at the other end, respectively, and are rotatable in a direction perpendicular to the hull length direction. Each cylinder 12 is equipped with a mechanism for detecting the hydraulic pressure and a control mechanism for maintaining the hydraulic pressure at a desired level. A passage plate 13 is pivotally attached to the bow and stern of the main hull 1.

When passing this ship under the bridge or the like, the cylinder 12 is contracted most as shown in FIG. Then, the arm 11 rotates upward to lift the float 2, and the gravity of the float 2 pushes the main hull 1 down into the water. In this way, the uppermost part of the float 2, which is the internal part of the main engine, is substantially coincident with the outer surface of the ceiling 5 of the passenger compartment 4 lowered to the lowest position. At that time, all the masts are tilted in the front-rear direction or the left-right direction, and the outer surface of this ceiling is the uppermost part of the main hull 1.

Next, when navigating in a shallow water such as a river, as shown in FIG. 4, the lower end of the bottom of the main hull 1 and the lower end of the lower surface of the float 2 are substantially aligned with each other.

When navigating in deep water such as a harbor, as shown in FIG. 5, when the cylinder 12 is extended, the arm 11 rotates downward and pushes up the main hull 1 above the water, thereby propulsion resistance. Can be reduced. If necessary, it is possible to further extend the cylinder 12 and push up the main hull 1 so that it is completely out of the water. At that time, the float 2 is submerged almost completely.

[0019]

[Effect of device]

 The variable water-draining vessel of the present invention navigates with a minimum of water-draining in a shallow water area, and in a deep water area, the main hull is positioned above the water to reduce propulsion resistance and enable high-speed navigation. By supporting the float with multiple arms and adjusting the position with a cylinder, the sway of the hull due to waves is reduced, and the weight of the float is used to push down the main hull while passing over bridges, etc. Can be lowered.
