[0016]

Embodiments of the present invention will be described with reference to the drawings. 1 to 4 show aspects of a propulsion device used for a ship or the like according to the present invention. FIG. 1 shows a valve seat 2 in a square or cylindrical tubular body 1 in a direction substantially perpendicular to the center axis thereof.
5 is provided, and the valve 2-1 is affixed to a rubber plate 2-3. When the cylindrical body 1 moves rightward in the drawing, the rubber plate 2-3 is opened due to its flexibility. You can move without.

On the other hand, when the cylindrical body 1 is moved to the left, the valve 2-1 closes and receives water resistance, so that the cylindrical body 1 receives a propulsive force in the right direction (Z direction) in the drawing. That is, in the reciprocating motion of the tubular body when the tubular body is moved forward and backward, the valve 2 is opened and moved forward when the tubular body is moved forward, and the valve 2 is closed when the tubular body is moved backward and the water in the tubular body 1 is moved in a direction opposite to the backward direction. Etc. can be promoted.

Here, the driving unit 3 moves the tubular body 1 to the left and right. The driving unit 3 is disposed at the bottom of a boat or the like and moves relatively to the boat or the like as described later. Or it is driven. In all drawings, + X
The direction is the forward direction of the tubular body including the valve, and -X is the opposite direction, that is, the direction in which propulsion is obtained. Z is the direction of propulsion, and W is the direction of discharging water. Also, the number of valves 2-1 may be one or more. The valve 2-1 can be provided with a rubber plate 2-3 attached to the back surface thereof to reduce the impact received from the tubular body when opened.

FIG. 2 shows another example of the structure of the valve. In this example, the rotating shaft 2-2 is located at a position displaced above the center of the cylindrical body.
When the tubular body 1 is moved to the right, the lower valve receives a greater mortgage, so that the valve rotates clockwise to minimize water resistance.

On the other hand, when the cylindrical body is moved to the left, the resistance of the water received on the lower side of the valve is greater than the resistance on the upper side. Therefore, the valve is closed and the groove is discharged as a whole to the left. Receives propulsion to the right. In this valve structure, the material of the valve does not rotate clockwise unless the specific gravity is slightly larger than that of water.

Further, other types of valves will be described. FIG. 3 shows a valve in which a forward valve and a reverse valve for switching between forward and backward movement by external power, for example, manually or mechanically, are incorporated as a set in one cylindrical body 1. In FIG.
1-a and 2-1-b, the holding plate 6-1 when moving forward (moving to the right) closes the valve 2-1-b, and the valve 2-1-a
Automatically closes and moves to the right without water resistance. On the other hand, at the time of retreat (movement to the left), the holding plate 6
-1 is opened, and the valve 2-1-b is opened and receives the resistance of water, so that the whole moves rightward. At this time, the valve 2-1-a is closed by the holding plate 6-1.

FIG. 4 shows another valve structure. This valve is 1
The plate-like valve has a rotating shaft 2-4 in the depth direction, and when the vehicle is moving forward (moving to the right), the valve is open so as not to receive water resistance as shown in the figure. To move the cylindrical body 1 to the left, the valve 2-1 is rotated and closed by valve driving means 9 such as a motor. There, the valve receives water resistance, so the hull propells to the right. For opening and closing the valve, an electric motor or the like can be used.

Hereinafter, a ship using any of the above valves as a propulsion device will be described. FIGS. 5 to 7 show an example of a boat provided with a pair of valves that can be switched between forward and backward, applied to a boat. A boat 7-1 equipped with a propulsion device according to the present invention in place of a paddle, and a valve 2-
A cylindrical body 1 having a and 2-b is provided on each of the left and right sides, and a valve direction switching handle 6 and a driving device 3 are provided.

Instead of paddles, when the driver grips the drive handles 3-1 provided on both sides of the boat and rows the boat back and forth along the edge of the boat 7-1, the force of the movement is increased by the cylindrical body 1 of the propulsion unit and the valve. The driving force is transmitted to the boat 7-1 by the driving device 2 and the driving device 3. As shown in FIG. 7, when the drive handle 3-1-1 is raised, the forward valve operates to move forward, and when the drive handle 3-1-1 is tilted sideways, the reverse valve operates to retract.

More specifically, a guide 3-5 of the drive unit 3 for transmitting the driving force of the rower's arm is attached to the edge of the boat as shown in FIG. A pulley base 3-3 is mounted on the guide 3-5 so as to be slidable back and forth through a pulley 3-3-1. The pulley base 3-3 has a handle 3-1-1 upward and a connecting member 3-11 downward.
Are connected to each other, and a set of valves 2 for forward and backward movement is provided below the water surface 4.
Is connected. The valve 2 is connected in a direction-switchable manner via a gear 6-4 and a valve link drive 6-5.

FIG. 6 shows the structure of the handle 3-1-1.
Press the lock pin on / off button 3-6 and push the pin 3-6
The structure is such that the handle is rotated to fall down by removing the lock of -1.

With the above-described apparatus, the rower grasps the rowing handle 3-1-1 of the propulsion device of the present invention instead of the conventional paddle, and horizontally reciprocates the pulley table 3-3 in the longitudinal direction of the boat. If you row, the boat 7-1 will be propelled. When the right handle is set to forward and the left handle is set to reverse, the boat 7-1 makes a sharp turn to the left, and when the right handle is set to reverse and the left handle is set to the forward, the boat 7-1 makes a sharp turn to the right. It is a boat propulsion device that allows you to move forward, backward, and turn freely by switching the handle.

FIGS. 8, 9, and 10 show an embodiment in which the valve drive propulsion device is applied to a hydroplane board. This is an example in which a hydroplane board is configured with a pair of valves that can be switched between forward and backward. This boat for a gliding board is provided with a guide tube 30-5 extending horizontally in the longitudinal direction and extending in the front-rear direction on a board 7-2 large enough to allow a person to stand on and surf stably.

The four types of propulsion devices are configured such that each propulsion device includes driving units 30-1 and 30-2 for hands and feet, a pulley base 30-3, and a cylindrical body 1
And the direction-switchable valve 2 is connected to one body. Drive units 30-1, 30-2 for hands and feet
A gear 30-4 is provided between the four pulley stands 30- connected to the guide cylinder 30-5 of the board 7-2.
3 is connected and incorporated via a gear 30-4 attached to a board 7-2.

FIGS. 11, 12, and 13 show the structure of the pulley base 30-3 in an enlarged manner. Pulley stand 30-3 has side rack 3
0-3-2 is engaged with a gear 30-4 fixed to the board, inserted into a guide cylinder 30-5 of the board 7-2, and a pulley 30-3-1 slides on the inner surface thereof. It is. On the upper part of the pulley base 30-3, a driving unit 30 for hand is provided.
-1 or the foot drive unit 30-2 is connected to the board 7
-2.

At the lower part of the pulley base 30-3, a connecting member 30-
11 protrudes downward from the through hole 7-2-1 of the board 7-2 and is connected to the tubular body 1 and the valve 2. An operation mode of the hydroplane board will be described. On a board 7-2 on which a person can stand and surf, a pair of propulsion units for a foot equipped with a cylindrical body 1 and a valve 2 are arranged at the center of the board, and the right and left are propelled through gears 30-4. On the other hand, a pair of hand-operated thrusters are installed on both outer sides thereof so as to be driven in the opposite direction to the foot via gears 30-4.

The propulsion unit for manual driving is a handle 30-1-1.
When it is driven up, it moves forward, and when it is driven inward, it moves backward. The direction switching handle 6-8 for the foot is installed at the toe, and can be switched between advance and reverse by switching in advance as needed. With the above device, when the person gets on the board, grasps the drive handle 30-1-1 with both hands, holds both feet in the foot drive unit 30-2 with a band or the like, and moves the four limbs as if walking, the four types are obtained. The thrusters move in opposite directions back and forth, so that thrust can be efficiently and smoothly obtained.

Therefore, the hydroplane board has a high propulsion efficiency by reliably capturing water with the cylindrical body 1 and the valve 2, and the four propulsion units, which move alternately in opposite directions, cancel out propulsion pulsation and rolling. The movement is smooth and smooth with little vertical movement of the body weight. As described above, the propulsion efficiency is high, the forward, the stop, the retreat, and the left and right turning can be freely performed, and the skiing on the water can be enjoyed like a ski.

Next, a description will be given of an embodiment of a valve-driven ship which is a propulsion device having the same structure as the above-mentioned water board in principle but using mechanical power such as a diesel engine without manual operation. 14 to 21 show an embodiment. FIG.
Indicates the overall configuration. The hull 7-3 is provided with a mechanical power 5, and the motive power is used to dispose the tubular body 1 below the hull 7-3 via the driving device 31 and to operate the valve 2 disposed in the tubular body 1. The hull 7-3 is advanced by moving forward and backward.

FIG. 16 is a sectional view taken along the line of FIG. FIG. 18 shows a cross-sectional view taken along the line wo of FIG. The tubular body 1 is fixed to the boat 7-3, and only the valve 2 is moved forward and backward. The thrusters consist of two central thrusters and two adjacent ones on both sides.
A set of four propulsion units with a constant propulsion force without pulsation is installed along the entire length of the bottom of the hull, and the valve 2 is moved forward and backward by mechanical power 5 to propell. It is a thruster.

In FIG. 16, the rotational force of the mechanical power 5 is converted into forward and backward movement by a crank mechanism 31-8.
The connecting member 31-11 is moved forward and backward by the crank arm 31-7. This connecting member 31-11 is connected to the valve 2 and
Forward and backward. The connecting member 31-11 is a guide cylinder 31-.
5 is a vertical pulley 31-3-1 and a horizontal pulley 31-3.
-3 smoothly advances and retreats. On both sides of the central two propulsors, there is a rack 31-12, which rotates a gear 31-4 and drives both propulsors via the racks provided on both propulsors.

FIG. 18 is a cross-sectional view taken along the line wo of FIG. In this figure, reference numeral 31-11 denotes a connecting member, and guide tubes 31- on both sides.
The pulley board 31-3 accommodated in the gear 5 is driven in the front-rear direction by the gear 31-4. 6-6 in FIG.
This is a motor that closes and opens the valve 2 when retreating. Further, the movement of the pulley board 31-3 forward and backward is performed by the connecting member 31-.
11 to the valve. As shown in the drawing, one pulley board includes a tubular body 1 provided with two valves, and includes four tubular bodies 1 as a whole.

FIGS. 19 and 20 show the valve 2 and the connecting member 31-.
FIG. 21 shows a detailed structure of a valve implemented in the eleventh embodiment. FIG. 19 is a longitudinal sectional view through the center of the connecting member 31-11. The connecting member 31-11 penetrates the bottom of the guide tube 31-5, and the airtight plate 31-9, the sealing material 31-10 and It is connected to the valve 2 through the through hole 7-3-1 of the hull. The sealing material 31-10 prevents water in the tubular body 1 from passing through the through-hole 7-3-1 and entering the hull.

The valve 2 is opened and closed by a motor 6-6 and a gear 6-4.
Is rotated, the valve gear 6-2 is rotated, and the valve presser 6-1 is operated. FIG. 20 is a cross-sectional view of the propulsion device. One cylindrical body 1 includes two valve driving devices, and each valve 2-1 rotates around an opening / closing axis 2-2 to open and close. FIG. 21 is a horizontal sectional view of the tubular body 1 shown in FIG. By rotating the central gear 6-2, the valve retainer 6-1 is operated to open and close the valve.

FIG. 1 shows the configuration of another embodiment of the propulsion device.
It is shown in FIG. Two valves (2-a, 2-b) are disposed at least twice the drive width (L0) on one cylindrical body 1, and the drive device 31 moves these two valves in opposite directions. Valve 2
a and a valve 2-b, and the valve 2-a is connected to the connecting member 3 via the mechanical power 5, the crank 31-8, the connecting rod 31-7, and the like.
Driven by 1-11. On the other hand, the valve 2-b is moved in the opposite direction by the gear 31-4 rotated by the rack 31-12 moving forward and backward together with the connecting member 31-1. As a result, this is an example in which the propulsion force is always applied without pulsation. In this embodiment, a pair of valves of the same shape that are driven in opposite directions provides a smooth pulsation-free propulsion force by pairing the pulsation propulsion force that works only when returning in reciprocating motion.

Further, as shown in FIG. 16, a check valve 8 for sucking air which is opened before and after the valve 2 is provided, so that an appropriate amount of air is sucked and air is mixed into the water in the cylinder, whereby the valve 2 is opened. Of the in-cylinder water, that is, the impact (water hammer) due to water, which is an incompressible body, can be reduced.

In the propulsion device of the present invention, when the valve 2 retreats by closing the valve, almost 100% of the movement acts on the mass of the whole water in the cylindrical body 1, that is, the inertia force, and the water is an incompressible body. Since a large impact (water hammer) is generated from the vehicle, the acceleration at the time of starting and at the time of stopping must be set small.

Valve 2 for avoiding impact during normal operation
An air suction pipe is provided before and after through a check valve 8 so that the valve back pressure opens and closes at a predetermined pressure, for example, 0.3 atm, so that air can be sucked and a water hammer can be avoided.

[0044]

As described above, the valve-driven boat according to the present invention is a small boat using the valve for a boat invented earlier. This ship is different from the conventional propeller type propulsion,
Since the on-off valve having a relatively simple structure is used as the propulsion device, an energy-saving small vessel suitable for economical middle and low speed can be realized. Therefore, the utility value of a boat, a hydroplane board or a small boat is high, and it greatly contributes to industrial development.
