Description

The present invention relates to a centrifugal propulsion device and a ship including the same. More specifically, the present invention relates to a centrifugal force propulsion device that can move forward and backward and a ship including the same.

Generally, as a propulsion device for a ship, a propeller and a jet drive system that ejects water are mostly used, and the most serious problem is that these are all inefficient.

Centrifugal force is a force that acts on an object moving along a curved trajectory outside the center of curvature, and its magnitude is simply proportional to the mass and radius of curvature of the rotating body and proportional to the square of the angular velocity. However, when the angular velocity of the object is increased to a certain extent, the size becomes surprisingly large.

As described above, since a strong force can be easily obtained by utilizing the centrifugal force, it has been used for the generation of artificial gravity in a dehydrator for a washing machine, a centrifugal separator, a space station, and the like. In addition, a general vehicle or submarine obtains its thrust by the action that interacts between the wheel and the ground-the half action force, the action that interacts between the propeller and the water-the half action force, respectively. In this case, the buoyant force is generated by the action between the wing and the air-the half acting force, whereas the centrifugal force motion can be generated, so that the object can be moved using the centrifugal force. Attempts to obtain thrust have continued.

However, such a conventional centrifugal force propulsion device and a ship including the conventional centrifugal force propulsion device have a problem that it is impossible to move forward and backward with one centrifugal force propulsion device.

FIG. 1 is a conceptual cross-sectional view schematically showing a centrifugal propulsion device and a ship including the centrifugal force propulsion device according to an embodiment of the present invention. FIG. 2 is a conceptual cross-sectional view schematically illustrating a centrifugal force propulsion device according to an embodiment of the present invention.

Referring to FIG. 1, the marine vessel may include an engine 15 installed in the main body 11 and a centrifugal force propulsion device 30 installed in a lower portion of the water surface 18. The ship can include a power shaft 16 that connects the engine 15 and the centrifugal propulsion device 30. That is, the centrifugal force propulsion device 30 can receive the rotational force of the engine via the power shaft 16.

Here, the power shaft 16 can be divided into a portion extended from the engine and a portion coupled to the centrifugal propulsion device 30. At this time, the power shaft 16 can be connected by a coupler or the like. Therefore, the centrifugal force propulsion device 30 can be easily separated from the main body 11 of the ship.
Further, the ship may further include a direction key 13 and a direction axis 12.

The centrifugal force propulsion device 30 rotates with respect to the central axis C to generate centrifugal force, and uses the centrifugal force to eject fluid from the inside in a certain direction (for example, radial direction), and reflects the ejected fluid. Then, it can be ejected outside to obtain thrust.

Further, the centrifugal force propulsion device 30 can obtain a thrust in both directions by ejecting fluid in the direction in which the two impellers face each other. The centrifugal force propulsion device 30 will be described in detail below.
The centrifugal propulsion device 30 can include two impellers and a power transmission unit 50.

The two impellers can be rotated by the power shaft 16 and face each other. Also, the two impellers can eject fluid in opposite directions. Hereinafter, the two impellers will be described as a first impeller and a second impeller.

The two impellers can eject the fluid from the inside in a certain direction, and can reflect and eject the ejected fluid. For example, the first impeller can eject fluid in the first direction. Here, the first direction may be opposite to the forward direction of the ship. The second impeller can eject fluid in the second direction. Here, the second direction may be opposite to the first direction and opposite to the reverse direction of the ship.
First, the impeller will be described with reference to FIGS.

FIG. 4 is an exploded perspective view of any one of the two impellers. Specifically, it is an exploded perspective view of a first impeller. Since the second impeller is the same as or similar to the first impeller, detailed description thereof is omitted.

Any one of the two impellers may include a reflective shade 32 and a plurality of blades 33. The impeller can include a shaft to which the plurality of blades 33 are radially coupled. Here, the shaft can be a shaft pipe 31 into which the power shaft 16 can be inserted as shown. Of course, the shaft is not limited to this.

The reflecting shade 32 is open at both ends, and the width can be increased from one end to the other end. For example, the reflecting shade 32 may be in the shape of a truncated cone or a funnel that is open at the top and bottom and vacant inside. Of course, the shape of the reflective shade 32 is not limited to a truncated cone.

At this time, the central axis of the reflective shade 32 can be parallel to the extending direction of the axial pipe 31. More specifically, the central axis of the reflective shade 32 and the central axis of the shaft pipe 31 can be placed on a substantially straight line.

The plurality of blades 33 are provided inside the reflection shade 32 and can be arranged radially from the rotation center thereof. Specifically, the plurality of blades 33 can be extended radially from the shaft pipe 31 at the same angle. At this time, the plurality of blades 33 can be coupled to the shaft pipe 31 by welding or the like.

The plurality of blades 33 can increase in width perpendicular to the rotation center axis C as the width (or radius) of the reflective shade 32 increases. For example, the plurality of blades 33 may have a substantially parallelogram shape.

On the other hand, the reflective shade 32 can rotate together with the plurality of blades 33. Specifically, the reflective shade 32 can be coupled to a plurality of blades 33. For example, the outer surfaces of the plurality of blades 33 can be fixedly coupled to the inner surface of the reflective shade 32 by welding or the like. Alternatively, the plurality of blades 33 and the reflective shade 32 can be integrally formed by casting.

On the other hand, the impeller can further include a streamlined guiding film 34 that gradually increases as the width of the reflection shade 32 increases around the rotation center axis C. For example, the guide film 34 can surround the shaft pipe 31 and be coupled to the shaft pipe 31 by welding or the like. At this time, the width of the guide film 34 perpendicular to the rotation center axis C can be smaller than the width of the plurality of blades 33. That is, the guide film 34 cannot exceed the plurality of blades 33.
Such a guide film 34 can guide the fluid passing through the reflective shade 32.

Accordingly, the first impeller can include the first reflecting shade 32, the plurality of first blades 33, the first guide film 34, and the first shaft pipe 31. The second impeller may include a second reflecting shade 37, a plurality of second blades 38, a second guide film 39, and a second shaft pipe 36. In the following description, it is assumed that the two impellers each include a reflective shade, a plurality of blades, a guide film, and an axial pipe, but the present invention is not limited to this.

At this time, as shown in FIGS. 1 and 2, the first reflecting shade 32 and the second reflecting shade 37 can face wide openings. The first impeller and the second impeller can have the power shaft 16 as the center of rotation. Further, the first impeller and the second impeller can rotate in opposite directions.

Specifically, the power shaft 16 can be inserted into the first shaft pipe 31 and the second shaft pipe 36. That is, the first shaft pipe 31 and the second shaft pipe 36 can surround the power shaft 16. At this time, the first shaft pipe 31 is not fixed to the power shaft 16 and can freely rotate. The second shaft pipe 36 is also not fixed to the power shaft 16 and can freely rotate.
Accordingly, the centrifugal force propulsion device 30 can move forward and backward with the single power shaft 16, and the configuration thereof can be simplified.
The first impeller and the second impeller can also serve as a nozzle when no fluid is ejected.

FIG. 5 is a plan view schematically showing an impeller of a centrifugal propulsion device 30 according to another embodiment of the present invention. According to the present embodiment, the plurality of blades 331 can be fixed by being radially attached between the shaft pipe 31 and the reflective shade 32. Each of the plurality of blades 331 is a plate material and can be a straight type.

FIG. 6 is a plan view schematically showing an impeller of a centrifugal propulsion device 30 according to another embodiment of the present invention. According to the present embodiment, the plurality of blades 332 are curved plate members and may be curved blades 332.

FIG. 7 is a front view schematically showing an impeller of a centrifugal propulsion device 30 according to another embodiment of the present invention. According to the present embodiment, the plurality of blades 333 may be propeller-type propeller blades 333 which are plate materials and are formed by being twisted into a certain shape.
Hereinafter, the power transmission unit 50 will be described with reference to FIGS. 1 to 3 again.

The power transmission unit 50 is provided between the power shaft 16 and the two impellers, and connects any one of the two impellers and the power shaft 16 according to the rotation direction of the power shaft 16 or other The impeller and the power shaft 16 can be connected.

The power transmission unit 50 may include two ratchet gears that connect the power shaft 16 and the two impellers, respectively. Specifically, the power transmission unit can include a first ratchet gear provided between the power shaft and the first impeller, and a second ratchet gear provided between the power shaft and the second impeller.

The two ratchet gears can be engaged when rotating in opposite directions. Specifically, the first ratchet gear is engaged when rotating clockwise, and can connect the power shaft 16 and the first impeller. The second ratchet gear is engaged when rotating counterclockwise, and can connect the power shaft 16 and the second impeller.

At this time, when one of the two ratchet gears rotates, the other one cannot rotate. For example, if the power shaft 16 rotates in a certain direction, the first ratchet gear can be engaged and rotated together with the power shaft 16, and the second ratchet gear can be detached and not rotate with the power shaft 16. If the power shaft 16 rotates in the opposite direction, the second ratchet gear is engaged and the first ratchet gear can be disengaged.
Therefore, the power transmission unit 50 can selectively connect the one power shaft 16 and the two impellers so as to be able to move forward and backward.
Since the first ratchet gear and the second ratchet gear are the same or similar, the first ratchet gear will be described in detail.

The first ratchet gear can include a first ratchet frame 51 on which a first latch 511 is installed, and a first gear 52 that makes a pair with the first ratchet frame 51. Here, the first ratchet frame 51 is coupled to the power shaft 16 by a frame fixing bolt 166, and the first gear 52 can be installed on the first impeller. The frame fixing bolt 166 will be described with reference to FIG.

More specifically, the first gear 52 can be coupled to the first induction membrane 34 by the first turbine bolt 341. Of course, the present invention is not limited to this, and the first gear 52 may be coupled to the first shaft pipe 31.

The first clasp 511 can be hooked or detached from the first gear 52 according to the rotation direction according to the rotation direction of the power shaft 16. For example, the power shaft 16 can now rotate clockwise. This will be described in detail later with reference to FIG.

The second ratchet gear can include a second ratchet frame 55 in which a second latch 551 is installed, and a second gear 56 that makes a pair with the second ratchet frame 55. Here, the second ratchet frame 55 is coupled to the power shaft 16 by a second hook 551, and the second gear 56 can be installed on the second impeller.

More specifically, the second gear 56 can be coupled to the inside of the second induction membrane 39 by the second turbine bolt 391. Of course, the present invention is not limited to this, and the second gear 56 may be coupled to the second shaft pipe 36.

Then, the second latch 551 can be engaged with or disengaged from the second gear 56 depending on the rotation direction of the power shaft 16. For example, the power shaft 16 can now rotate counterclockwise. This will be described in detail later with reference to FIG.

Meanwhile, according to another embodiment of the present invention, the centrifugal propulsion device 30 can be fixed to the main body 11 of the ship and further includes a fixed partition 63 provided between the two impellers. it can.

The fixed partition plate 63 has a substantially plate shape and can be arranged long along the extending direction of the power shaft 16. Therefore, the fixed partition 63 can make the flow of fluid parallel to the direction of the power shaft 16.
A plurality of such fixed partition plates 63 may be provided radially with reference to the power shaft 16.

Any one of the fixed partition plates 63 may be extended in the direction of the main body 11 of the ship and fixedly coupled to the main body 11. Alternatively, as illustrated, any one of the fixed partition plates 63 may be directly or indirectly connected to the installation frame 61, and the installation frame 61 may be fixedly installed on the main body 11 of the ship by installation bolts 611. . The centrifugal force propulsion device 30 may further include an installation frame 61 and an installation bolt 611.

On the other hand, the centrifugal force propulsion device 30 can further include a fixed outer cylinder 62 that is a case. The fixed outer cylinder 62 is provided between the two impellers and can surround the fixed partition plate 63. The fixed separator 63 can be connected and fixed radially to the inner peripheral surface of the fixed outer cylinder 62. Moreover, the fixed outer cylinder 62 can couple | bond the installation frame 61 with an outer surface.

Meanwhile, the centrifugal force propulsion device 30 may further include a bearing unit provided between the fixed partition 62 and the power shaft 16. The bearing unit can include a bearing housing 65 and a bearing 67.

The bearing housing 65 is provided between the two impellers and can be provided approximately between the two impellers. Further, the bearing housing 65 can surround the power shaft 16. In addition, the fixed partition 63 can be radially coupled to the bearing housing 65. That is, the fixed partition 63 can be provided between the fixed outer cylinder 62 and the bearing housing 65. The bearing housing 65 may be streamlined so as to facilitate fluid flow.

The bearing 67 is provided inside the bearing housing 65 and can be coupled to the bearing housing 65 and the power shaft 16. Therefore, the bearing unit can support the power shaft 16 as well as help the power shaft 16 to rotate smoothly.

On the other hand, when one of the two impellers rotates, the other can be fixed. Specifically, when the first impeller rotates, the second impeller needs to be fixed so as not to disturb the fluid flow. Of course, the opposite is also true.

Therefore, the centrifugal force propulsion device 30 may further include a fixing unit that selectively fixes the two impellers. For example, when the first impeller rotates, the fixed unit can stop the second impeller and prevent it from rotating at the fluid ejection pressure. Of course, the opposite is also possible.

The stationary unit may include a brake plate 68 that moves according to the fluid flow. Here, the brake plate 68 is installed on the fixed partition plate 63 and may have a length capable of contacting an adjacent impeller of the two impellers. Specifically, one end of the brake plate 68 adjacent to the first impeller is rotatably coupled to the fixed partition plate 63, and the other end can be free. Therefore, if the brake plate 68 rotates in the first impeller direction, the brake plate 68 can be maintained in a state where it comes into contact with the first impeller and the first impeller is stopped.
A plurality of such brake plates 68 can be adjacent to the first impeller and the second impeller, respectively.

The fixed unit may include a brake shaft 681 that rotatably installs the brake plate 68 on the fixed partition plate 63. The brake shaft 681 can be installed substantially perpendicular to the fluid flow direction. That is, it can be installed in a direction substantially perpendicular to the braking shaft 681 and the power shaft 16.

Meanwhile, the fixed unit may further include a brake shaft plate 682. In other words, the brake shaft plate 682 can be coupled to the fixed partition plate by welding or screws, and the brake plate 682 can be rotatably coupled by the brake shaft 681. Two such brake shaft plates 68 may be provided adjacent to the first impeller and the second impeller, respectively.
The operation of the fixed unit will be described below.

When the first impeller rotates, the two brake plates 68 can be disposed in the first direction by the fluid ejected from the first impeller. At this time, the brake plate 68 adjacent to the second impeller can be prevented from rotating in contact with the blade 38 of the second impeller.

Conversely, when the second impeller rotates, the two brake plates 68 can be disposed in the second direction by the fluid ejected from the second impeller. At this time, the brake plate 68 adjacent to the first impeller can be prevented from rotating in contact with the blades 33 of the first impeller.

8, 9 and 10 are a conceptual view and a perspective view schematically showing a centrifugal force propulsion device 30 and a ship including the same according to still another embodiment of the present invention. The centrifugal force propulsion apparatus 30 according to the present embodiment and the ship including the same are the same as or similar to the centrifugal force propulsion apparatus 30 according to the above-described embodiment and the ship including the same, and thus a duplicate description is omitted.

Referring to FIG. 8, the marine vessel may include an installation plate 25 that is rotatably coupled to the main body and on which the centrifugal force propulsion device is installed. Specifically, the installation plate 25 can be rotatably coupled to the main body by the hinge 22. Meanwhile, the marine vessel may further include a fixing bolt 26 that couples the installation plate 25 and the main body 11 in order to firmly couple the installation plate 25 to the main body 11. Here, the fixing bolt 26 can connect the installation plate 25 and the main body 11 at a position far from the hinge 22.

Further, the marine vessel may further include a moving ring 28 coupled to the installation plate 25 in order to rotate the installation plate 25 more smoothly in the main body 11 and maintain the rotated state. Here, the moving ring 28 can be arranged at a position far from the hinge 22.

As shown in FIG. 9, therefore, the operator can rotate the installation plate 25 with the moving ring 28. Then, the operator can keep the installation plate 25 rotated by tying a rope or the like to the moving ring 28.

At this time, the ship may further include a water shielding wall 21 installed in the main body. The impermeable wall 21 may include a moving hole 29 that is installed approximately perpendicular to the water surface and into which the moving ring 28 can be inserted.

Therefore, the operator can rotate the installation plate 25 until the moving ring 28 is inserted into the moving hole 29. Then, the operator can insert a pin or the like into the moving ring 28 inserted in the moving hole 29 and fix it to the water shielding plate 21.

On the other hand, in order for the installation plate 25 to rotate, the power shaft 16 needs to be separated. For example, the power shaft 16 can be separated into a portion coupled to the engine 15 and a portion coupled to the centrifugal propulsion device 30. Specifically, the power shaft 16 can include at least two shafts that can be coupled and separated. At this time, the power shaft 16 can be divided into a plurality of parts that can be fitted to each other. Specifically, the power shaft 16 can be separated and coupled in the form of a slip joint.
Hereinafter, an example of the coupling and separation structure of the power shaft 16 will be described.

Referring to FIGS. 8, 9 and 10, the power shaft 16 includes a shaft directly coupled to the engine, a shaft directly coupled to the centrifugal propulsion device 30, and a connecting shaft connecting the two. Can do. Here, the portion directly coupled to the centrifugal propulsion device 30 is referred to as a turbine shaft 160 below. The connecting shaft is hereinafter referred to as a slip power shaft 80.

The shaft of the power shaft 16 that is directly coupled to the engine can include a power protruding slip 17 at its end. The slip power shaft 80 can include a slip groove 82 into which the power projecting slip 17 is inserted at one end, and a connecting projecting slip 83 at the other end. The turbine shaft 160 may include a turbine shaft groove 169 that inserts a connecting protruding slip 83 at one end.

At this time, the power projecting slip 17 and the slip groove 82 may have shapes corresponding to each other. The same applies to the connecting protruding slip 83 and the turbine shaft groove 169.
The marine vessel may further include a shaft bolt 86 that couples through the slip power shaft 80 and the power projecting slip 17 to provide a firm connection.

Since the slip power shaft 80 penetrates the main body 11 of the ship, it is necessary to reduce friction. Therefore, the ship can further include a fixed bushing 78 that is installed in the main body 11 and through which the slip power shaft 80 passes. The slip power shaft 80 can include a slip friction portion 81 inserted into the fixed bushing 78. Here, the slip friction part 81 can be substantially pipe-shaped.

On the other hand, the slip power shaft 80 can move in the axial direction for coupling or separation. At this time, in order for an operator to move the slip power shaft 80 more easily, the ship may further include a moving handle 88 fixedly coupled to the slip power shaft 80. The moving handle 88 can be provided inside the main body 11.
The separation of the centrifugal force propulsion device 30 will be described with reference to FIGS. Since the coupling of the centrifugal force propulsion device 30 is in the reverse order of separation, detailed description thereof is omitted.

When separating the centrifugal force propulsion device 30 for repair, the operator removes the shaft bolt 86 and pulls the moving handle 88 toward the engine 15 so that the slip power shaft 80 inserted into the centrifugal force propulsion device 30 is removed. Can be extracted.

Then, the operator can loosen the fixing bolt 26 coupled to the installation plate 25 and move the installation plate 25 on which the centrifugal force propulsion device 30 is installed with the hinge 22 as a vertex so as to lean against the impermeable wall 21 side. At this time, the moving ring 28 can be inserted into the moving hole 29.

On the other hand, with reference to FIG. 10, the coupling relationship between the turbine shaft 160 and the centrifugal propulsion device 30 will be described in detail. In this drawing, the turbine shaft 160 may be the same as or similar to the power shaft 16 of FIG. Also, the connection relationship can be similar.

On the other hand, the turbine shaft 160 can be connected to the first ratchet frame 51 and the second ratchet frame 55 on both sides by frame fixing bolts 166, respectively. The first gear 52 and the second gear 56 can be installed as described above.

The first ratchet gear may further include a latch shaft 519 and a latch spring 518. The coupling between the first ratchet frame 51 and the first gear 52 can be determined by the direction combined with the latch spring 518 that inserts and supports the first latch 511 on the latch shaft 519. The connection between the second ratchet frame 55 and the second gear 56 can be said to be the same.

According to the above description, the slip power shaft 80 has been described as being included in the ship as a component of the power shaft 16, but is not limited thereto, and may be included in the configuration of the centrifugal propulsion device 30. it can.

On the other hand, the centrifugal force propulsion device 30 may include two nozzles 71 and 72 disposed adjacent to the outside of the two impellers, respectively. The two nozzles 71 and 72 can be configured to effectively contain the fluid ejected from the two impellers. That is, the two nozzles 71 and 72 can smoothly inflow and eject the fluid. Specifically, the two nozzles 71 and 72 include a first nozzle 71 and a second nozzle 72.

The first nozzle 71 can be adjacent to the narrow opening of the first impeller. For example, the first nozzle 71 may have a shape that gradually spreads in a shape opposite to the first reflecting shade 32. At this time, the centrifugal force propulsion device 30 may include a fixed shade 73 that surrounds the first reflective shade 32. The fixed shade 73 is substantially the same as the shape of the first reflective shade 32 and can be slightly larger. The fixed shade 73 can be combined with the first nozzle 71.
The first nozzle 71 and the fixed shade 73 are coupled to the housing 75, and these can be coupled to the ship body 11 by welding or the like.

The second nozzle 72 can be adjacent to the second impeller. The second nozzle 72 can be adjacent to the narrow opening of the second impeller. More specifically, the second nozzle 72 can be adjacent to the second reflective shade 37.
