Description

[0001] An impellent force generator for floater [

More particularly, the present invention relates to a thrust generator for generating a thrust by receiving kinetic energy from the outside, and more particularly, to a thrust generator for generating a thrust by selectively exerting contact with a fluid during rotation, To thereby maximize the amount of thrust generated.

BACKGROUND ART [0002] Conventional leisure sports equipment has conventionally been used, such as a commercial bicycle or a duck boat, which rides on a surface of a water surface by a driving force generated by a pedal stepping on a pedal.

Such a device is configured so that a rotor, such as a wheelbarrow, can be driven by the propulsive force obtained by pumping a furnace without using an engine or pedaling with a foot.

However, there is a disadvantage in that boats that move by paddling, or so-called ducks, can be used at a relatively low cost, but are slow in speed.

This is because the boats that wet the boats are forced to climb the arms by the means of obtaining propulsion, and the ducks are driven by the simple chains of the gears connected to the foot pedals and the gears connected to the rotating body. This is because the efficiency is lowered.

A conventional structure will be described with reference to FIG.

1 is a perspective view showing the configuration of a pedal-driven watercraft, which is a Korean Utility Model Registration No. 20-0400112 registered in Korea.

As shown in the figure, a conventional water boat has buoyant bodies 16 on both sides thereof. The buoyant body 16 is connected by a front fixed shaft 1 and a rear fixed shaft 2, and the front fixed shaft 1 And the rear fixing shaft 2 are connected by the longitudinal axis 3 to maintain their shape.

A pedal 10 connected by a chain 14 is provided under the saddle 7 and a steering wheel 5 is disposed in front of the pedal to adjust the direction.

A driven gear 13 is coupled to the rear side of the chain 14 and the driven gear 13 receives the force provided to the pedal 10 through the chain 14 to rotate the propeller 12.

However, the water boat constructed as described above has the following problems.

That is, since the propeller 12 maintains a certain angle with respect to the center of rotation of the driven gear 13 during rotation, the thrust generated with respect to water from the intake to the outflow is not constant. That is, even if the propeller 12 is submerged in water or rises above the water surface, the propeller 12 always maintains the state toward the rotation center, so that the thrust generation efficiency is lowered.

Accordingly, since the contact area is changed differently depending on the degree of locking in contact with water in order to generate thrust, it is difficult to generate thrust effectively.

In addition, since the propeller 12 always maintains a constant angle with respect to the center of rotation, it is impossible to adjust the magnitude of thrust generation.

Needless to say, the power unit such as a motor may be applied to the pedal 310 within a range where the pedal 310 can rotate by providing a force to the driving unit 320.

The driven rotatable member 340 is coupled to the rotation bar 140 to be described below, and can be rotated integrally with the rotation center of the rotation bar 140 as a reference.

The thrust generator 100 is provided with a plurality of thrust blades 110. The thrust blade is configured to revolve around the same center as the rotation center of the driven rotatable member 340 when the driven rotatable member 340 rotates, and to maintain a constant phase.

That is, the multiple thrust blade 110 may be maintained in an upright state as shown in FIG. 2 or may be rotated and fixed as shown in FIG. 9 according to a user's need.

Therefore, the plurality of thrust blades 110 are always kept at the same angle with each other even if they are immersed in water or placed on the water surface, and the size of the thrust generated when the water is in contact with the water can be adjusted.

Of course, the multiple thrust blade 110 maximizes the amount of thrust generated by maximizing the contact area with the water as shown in FIG.

The configuration of the force switching portion (reference numeral 150 in FIG. 7) for causing the thrust blade 110 to maintain a phase (e.g., a vertical state) will be described in detail below.

The plurality of thrust blades rotate about the support shaft 120. When the thrust vane 110 is kept in a predetermined phase, the rotation of the supporter shaft 130 is limited to the rotation of the supporter 130 And can be rotated by releasing the restraint between the support table 130 and the support shaft 120 when necessary.

That is, the support shaft 120 is fixed so as not to rotate with respect to the support 130 by the phase switching means 200, which will be described in detail below. When the magnitude of the thrust is adjusted, that is, So that free rotation of the support shaft 120 can be made possible.

The thrust generation magnitude can be varied by rotating the support shaft 120 by operating the feed force unit 220, which is a component of the phase switching unit 200.

A rotation bar 140 is provided on the outer side of the support shaft 120. The rotation bar 140 is installed to freely rotate with respect to the support shaft 120. A thrust blade 110 is freely rotatable on the other side of the rotation bar 140, Lt; / RTI >

The rotation bar 140 may have a predetermined space therein and may include a force switching unit 150, which will be described below, and may be sealed to block the inflow of water when the rotation bar 140 is immersed in water.

Further, the rotation bar 140 has a structure capable of assembling or repairing the force switching part 150.

That is, the rotary bar 140 is provided with a lid or a door so as to open the inside.

The plurality of rotation bars 140 may be coupled to the support shaft 120 at different angles.

It is obvious that the number of the thrust blades 110 may be increased or decreased according to need.

When a plurality of the rotation bars 140 are provided, they further include a reinforcing bar 146 and are integrated with each other to rotate at the same time during rotation.

That is, the multi-rotation bar 140 simultaneously rotates at a constant speed at the same time.

The rotation bar 140 may be formed to have a streamlined cross-section so that the resistance of the rotation bar 140 when contacted with water is minimized.

Hereinafter, the configuration of the thrust generator will be described in more detail with reference to FIGS. 4 to 6. FIG.

FIG. 4 is a longitudinal sectional view showing a state of use of the thrust generating device for a floating body according to the present invention, FIGS. 5 and 6 show an embodiment in which the phase switching means is not provided in the thrust generating device for a floating body according to the present invention, There is shown a longitudinal sectional view showing an internal configuration of an embodiment having a phase switching means.

The plurality of thrust wings 110 are configured such that straight lines passing through respective centers of gravity are parallel to each other and positioned at the same distance from the support shaft 120 and have the same surface area (area in contact with water).

Since the support shaft 120 is fixed to the supporter fixed to the upper side of the float F so that only the rotation bar 140 and the thrust blade 110 can be contained in the water, do.

The support shaft 120 is fixed not to rotate with respect to the support base 130 and penetrates the rotation bar 140 to serve as a rotation center of the rotation bar 140.

The rotation of the support shaft 120 is limited by the phase switching means 200 and is fixed through the driven rotatable member 340.

The support shaft 120 is selectively rotatable with respect to the support 130 by the operation of the feed force unit 220, which is one component of the phase switching means 200.

The support shaft 120 is provided with a rotation bar 140 capable of freely rotating with respect to the support shaft 120. The thrust blade 110 is freely rotatable with respect to the rotation bar 140.

To this end, a first rotation guide member 142 is provided inside the rotation bar 140. The first rotation guide member 142 is configured to guide the rotation bar 140 to rotate with respect to the support shaft 120 fixed to the support base 130. The bearing is preferably applied to the inner ring, The shaft 120 is inserted and the outer ring is brought into contact with the inside of the rotating bar 140 to help free rotation of the rotating bar 140.

A second rotation guide member 144 is provided on the other side of the rotation bar 140 on which the first rotation guide member 142 is not installed.

The second rotation guide member 144 is in contact with the inner ring of the shaft 112 protruding from both sides of the thrust blade 110 and serving as a rotation center of the thrust blade 110, Thereby allowing the shaft 112 to rotate freely with respect to the rotating bar 140. [0064]

That is, when the force switching unit 150 to be described below is not provided, the rotation bar 140 is freely rotatable about the support shaft 120 by the first rotation guide member 142, The shaft 112 is freely rotatable with respect to the rotation bar 140 by the second rotation guide member 144. [

Meanwhile, the thrust blade 110 maintains the phase (vertical state) regardless of the position.

The shaft 112 of the thrust wing 110 revolves around the support shaft 120 without rotating even if the rotation bar 140 rotates about the support shaft 120 in the rotation bar 140 A force switching unit 150 is provided to maintain a constant phase.

The force switching unit 150 rotates the rotary bar 140 with respect to the support shaft 120 so that the phase of the thrust blade 10 can be maintained.

That is, the force switching unit 150 includes a first force switching member 152 axially coupled to the axis 112 of the thrust wing 110, and a second force switching member 152 axially coupled to the supporting shaft 120. [ The first force switching member 152 and the second force switching member 154 are slidably coupled to each other and the first force switching member 152 rotates when the rotating bar 140 rotates, And a third force switching member 156 for limiting the force.

The second force switching member 154 is fixed to the support shaft 120 so as not to rotate with respect to the support base 130 and the first force switching member 152 is fixed to the shaft 112.

The first force switching member 152 and the second force switching member 154 are spaced apart from each other by a predetermined distance by the rotation bar 140. The first force switching member 152 rotates But is configured to revolve only on the support shaft 120 as a reference.

The third force switching member 156 provides a tension between the first force switching member 152 and the second force switching member 154 when the thrust vane 110 makes contact with the fluid to generate thrust, So that the thrust wing 110 is kept in a phase (vertical state) by restricting the switching member 152 from rotating.

7) formed on the inner surface of the third force switching member 156 is engaged with the irregularities formed on the outer surfaces of the first force switching member 152 and the second force switching member 154, The first force switching member 152 and the second force switching member 154 do not rotate when the rotating bar 140 is not rotated.

The first force switching member 152 and the second force switching member 154 have the same outer diameter and the concave and the convex formed on the first force switching member 152 and the second force switching member 154 are the same Size and shape.

The concavities and convexities formed on the third force switching member 156 may also have the same size and shape as those of the first force switching member 152 and the second force switching member 154.

Accordingly, the first force switching member 152 and the second force switching member 154 may be sprockets or pulleys, and the third force switching member 156 may be a range in which slippage is prevented such as a chain, a timing belt, Various changes can be made within the scope of the present invention.

Although it is not shown, it is obvious that the force switching unit 150 may further include a tension holding member for holding the tension of the third force switching member 156 in various ways.

Therefore, the first force switching member 152 is fixed so as not to freely rotate about the shaft 112, and the second force switching member 154 is fixed to the support shaft 120 so that it can not rotate freely The third force switching member 156 restricts the free rotation of the thrust blade 110. As shown in FIG.

The shaft 112 and the thrust blade 110 may be integrally formed, and may be coupled using a coupling member such as a bolt for easy repairing.

Between the rotation bars 140, a reinforcing bar 146 may be further provided. The reinforcing bar 146 has a structure for reinforcing the strength of the rotating bar 140 by connecting both ends of the rotating bar 140 to the pair of the rotating bars 140. In order to prevent the twisting of the rotating bars 140, And the reinforcing table 146 can be variously modified within a range that does not interfere with the rotation of the thrust blade 110.

The rotary bar 140 is coupled to the rotary bar 140 while maintaining a constant angle and rotates together with the driven rotary member 340 so that all thrust blades 110 can generate thrust.

For this purpose, the rotary bar 140 is integrated by the adjacent rotary bar 140 and the reinforcing bar 146.

As shown in FIGS. 5 and 6, the apparatus 100 may be provided with a phase switching unit 200 selectively.

The phase switching means 200 changes the angle of the thrust blade 110 by rotating the support shaft 120 (see FIG. 9), thereby performing the shift function according to the change of the contact angle with the fluid.

The details of the configuration of the phase switching means 200 will be described below, and the essential configuration required for the embodiment in which the phase switching means 200 is not provided will be described with reference to FIG. 5 .

When the phase switching means 200 is not provided as shown in FIG. 5, the supporting member 130 is provided with a restricting member 122 for selectively rotating the supporting shaft 120.

The restricting member 122 restricts the support shaft 130 and the support shaft 120 to each other so that the support shaft 120 is not rotated and the restraint is selectively released so that rotation of the support shaft 120 is permitted Lt; / RTI >

Therefore, when the restraint member 122 rotates the support shaft 120 by using the handle 124 or the like while the restraint of the supporter 130 and the support shaft 120 is released, the angle of the thrust blade 110 .

Hereinafter, the action of the force switching unit 150 will be described in more detail with reference to FIG.

7 is an outline view for explaining an action of a force switching portion which is a constitution of a thrust generating device for a floating body according to the present invention;

Referring to P1, P2, S1 and S2 shown in FIG. 7, the rotation bar 140 is rotated in the counterclockwise direction by the force provided by the force providing means 300, , The specific point S1 of the third force switching member 156 moves to the S2 position as the third force switching member 156 rotates clockwise.

On the other hand, P1, which is a specific point of the axis 112, is rotated by? In the clockwise direction as S1 moves to S2, and is placed at the position P2. As a result, P1 and P2 are shifted only in a state in which the axis 112 is not rotating, and the phases are in the same state.

This is because the first force switching member 152 is in contact with the third force switching member 156 and the first force switching member 152 rotates about the second force switching member 154, And the member 152 is engaged with the third force switching member 156 and rotated by a certain angle in the third force switching member 156. [

Accordingly, the specific point can be maintained in the same phase regardless of the rotation of the rotary bar 140 by the action of the first force switching member 152 and the third force switching member 156.

For example, if it is assumed that the first force switching member 152 is coupled to the outer surface of the shaft 112 having a specific point on one side of the inner circumferential surface thereof by welding or the like, Since the specific point is always located in the same phase (upper side), the thrust blade 110 can also maintain the phase (vertical).

8 is a schematic view for explaining the direction of movement of the float during operation of the force switching unit, which is a constitution of the thrust generating device for a floating body according to the present invention.

When the thrust wing 110 is in contact with the fluid and the driven member 340 rotates to rotate the thrust wing 110 as shown in the accompanying drawing, And the thrust is generated by rotating clockwise.

By the thrust, the float can move in the left direction.

At this time, since the thrust vane 110 always maintains the phase (vertical state), the contact area with the water is kept at a maximum to generate a large thrust force. When the thrust force vanishes after the thrust is generated, The thrust wing 110 descends below the water surface and generates a thrust, thereby achieving a continuous thrust.

Meanwhile, the thrust generator for a floating body according to the present invention can artificially control the amount of thrust generated by changing the contact area of the thrust blade 110 and the fluid when speed control is required.

To this end, the thruster generating apparatus 100 is provided with a phase switching means 200.

The detailed configuration of the phase switching means 200 will be described below with reference to FIGS. 2, 6 and 10 to 12 attached hereto.

Fig. 10 is a partial vertical sectional view showing the detailed configuration of the phase switching means, which is a constitution of the thrust generating device for a floating body according to the present invention, and Fig. 11 is a partial vertical sectional view showing the operation of the phase switching means Fig. 12 is a schematic view showing the principle of rotation of the support shaft during operation of the phase switching means, which is a constitution of the thrust generating device for a floating body according to the present invention.

10, the phase shifting means 200 includes a second speed change rotary member 210 axially coupled to the support shaft 120 like the support shaft 120, a second speed change rotary member 210 coupled to the second speed change rotary member 210, A transmission force unit 220 for forcing the transmission member 230 to move and a transmission force unit 220 for transmitting the movement of the transmission force unit 220, And a first speed change rotary member 250 interlocked with the speed change member 230 and the second speed change rotary member 210. [

The second speed change rotary member 210 is coupled to the support shaft 120 and rotates in conjunction with the support shaft 120. The second speed change rotary member 210 is interlocked with the first speed change rotary member 250 in the same direction .

Therefore, when the second speed change rotary member 210 is not rotated, the rotation of the support shaft 120 is restricted, and when the rotation bar 140 rotates, the thrust blade 110 maintains a constant phase do.

The transmission 230 is limited in its movement by the action of the feed force unit 220 and the restraining unit 240. When the feed force unit 220 is operated to move the speed change member 230, The shaft 120 is rotated by interlocking of the first speed change rotary member 250, the transmission member 230, and the second speed change rotary member 210. [

Meanwhile, the phase switching means 200 is configured to restrict the rotation by providing a constraining force to the support shaft 120, and to selectively rotate the support shaft 120 by releasing the constraining force selectively.

11, the support shaft 120 is allowed to rotate the support shaft 120 with respect to the support base 130 by releasing the constraint between the feed force unit 220 and the restricting unit 240. [

If the user using the thrust generator 100 wants to reduce the amount of thrust generated, the feed force unit 220 is moved in a state in which the force of the feed force unit 220 and the force of the restraining unit 240 are canceled, The thrust wing 110 can be rotated so as to have various angles with respect to the water surface as shown in FIG. 9 by rotating the first speed change member 230 and the second speed change rotary member 210.

Hereinafter, the operation principle of the phase switching means 200 will be described with reference to FIG.

As shown in the drawing, the phase switching means 200 is configured to prevent the support shaft 120 from rotating with respect to the support base 130, and if necessary, to rotate the support shaft 120 to adjust the amount of thrust generated .

That is, the constraining force between the support shaft 130 and the support shaft 120 is canceled by releasing the restraint of the feed force unit 220 and the restraining unit 240, The support shaft 120 is rotated by operating the feed force unit 220 to rotate the first speed change rotary member 250.

When the support shaft 120 rotates counterclockwise (see the arrow in FIG. 12) with respect to the support base 130 and the specific point S2 is shifted to the specific point P2, the second force switching member 154 ) Causes the third force switching member 156 to draw a closed loop in the counterclockwise direction and the first force switching member 152 rotates the shaft 112 (at a specified point P3 to a specific point S3) So that the angle of the thrust blade 110 can be changed.

When the phase of the thrust blade 110 is to be maintained as shown in FIG. 12, the movement of the support shaft 120 is restrained by restricting the movement of the feed force part 220 into the groove of the restraining part 240 do.

The thrust generator 100 can adjust the angle of the thrust blade 110 using the phase switching means 200 so that a different thrust can be generated even if the force provided from the force providing means 300 is kept constant. Do.

That is, the phase switching unit 200 may perform the same function as the transmission of the vehicle by adjusting the contact angle between the thrust blade 110 and the water to increase or decrease the thrust generation efficiency.

The scope of the present invention is not limited to the above-described embodiments, and many modifications may be made by those skilled in the art based on the present invention.

13, the thrust wings 110 are provided on both sides of the rotating bar 140. A connecting member P is installed at the center of the rotating bar 140 to connect the connecting member P and the rotating bar 140 The power supply means 300 and the phase switching means 200 are provided at the right side of the connecting member P so that the rotation of the rotating bar 140 and the phase of the thrust blade 110 Conversion may be possible.

Further, in the embodiment of the present invention, the thrust blade 110 is configured to have a rectangular plane, but it is also possible to change the shape of the thrust blade 110 to various shapes and to have a curvature if necessary.

It is also possible to construct the thrust blade 110 to cut and remove even if it comes into contact with dirt such as vinyl, sling, fishing line, etc. by attaching irregularities or blades to corner portions of the thrust blade 110.
