Abstract

PURPOSE:To enable a stable sail in all weathers by placing a ship body above the waterline, submerging a submarine hull under the water and coupling both with each other through entrance bodies to adjust the buoyancy by lateral steers provided in the front and rear of said submarine hull. CONSTITUTION:When a submarine hull 1 submerges and sails under the water surface WL-2 and waves W-1 approach said hull 1, the buoyancy of +B in the front of an entrance body 3 is increased, whereas a lateral steer 5' is inclined forward downward to form descending buoyancy -F and maintain constant the depth of the front of the entrance body 3 to the water surface WL-2. Also, when the waves W-2 approach relatively the rear of the entrance body 3, the buoyancy of the rear of entrance body 3 is reduced by -B, whereas the depth of the rear of entrance body 3 to the water surface WL-2 is maintained constant by the action of the floating force +F of lateral steer 5''. Thus, the longitudinal horizontality of a ship 2 is stabilized. In the case of rolling, the lateral steers 5''', 5'''' are operated to set the ship 2 to the horizontal state.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The disclosed technology is applicable to the field of structural technology for ships, including extremely large ships that can sail not only near coastal waters but also on the open ocean.

<Summary of the gist> Therefore, the present invention is equipped with a side rudder that enables the vertical movement of the ship, forward heeling, and backward heeling movement with respect to the water surface, not only in the submerged state but also in the floating state. At least two submersible hulls, such as teardrop type hulls, are set below the water surface, and the submersible hulls and the ship body provided above the water surface are formed in a shape that reduces water flow resistance on the water surface. This invention relates to the structure of a surface-navigating ship that is integrally connected via a water cutter and has a longitudinal rudder for changing the navigation direction and a propulsion device such as a screw. Buoyancy (if it changes due to waves and winds during navigation, centrifugal force due to turning during navigation, etc., the amount of change is less than the flotation or sinking ability of the side rudders installed at least at the front and rear of the submersible hull below the water surface) This invention relates to a constant depth semi-submersible surface navigation vessel structure formed as follows.

<Prior art> As is well known, common activity areas include land, water, and
There are three types of air: land is the place for activities of land animals such as running, air is the place for birds to fly, and underwater is the place for the lust of fish. In addition, birds are active both in the air and on the ground, and some fish are active both in the water and in the air.Humans have developed as mammals. began to operate on the surface of the water between the water and the air through the technical means of ships.

Throughout history, from ancient bowl ships to modern giant ships, ships are basically shaped like a bowl to reduce water flow resistance, and the buoyancy of the removed water changes the water surface. The ship floats up to the surface, and the height of the ship's side left above the water surface allows it to retain reserve buoyancy and maintain the ability to recover even if the ship tilts, and the propulsion device uses paddles, rods, and wind power.
In modern times, it was made to move forward using mechanical force such as a propeller, but the principle remains essentially unchanged even up to the present day.

In the early modern period, ships such as deep-sea boats and submarines that could travel submerged underwater were a revolutionary technological development for ships that could only travel on the surface of the water.

However, for a submerged vessel of this type, the submergence time is long.
In the past, energy from storage batteries, etc. was limited over time, and long-term submerged operation was limited even in submarines equipped with so-called snorkel equipment, but recently, the use of nuclear power has made it possible to operate indefinitely over time. However, it has the disadvantage that it is difficult to handle and is not economically viable due to the restriction that it must be operated under conditions that are dangerous to the reactor and its peripheral equipment.

Therefore, among commercial ships whose commercial base cannot be ignored, ships that navigate on water have been used for a long time.

Naturally, surface-going vessels are equipped with propulsion engines that require oxygen from the atmosphere, which poses the following problems.

In other words, pitching and rolling are extremely unpleasant phenomena for ships that float on the surface of the water, and even though we know that pitching and rolling are the things that guarantee the ship's resilience, we are not mentally aware of them. In addition, it is inevitable that ships will experience emotional instability while sailing, and while it is possible to deal with this by installing stabilizers on medium-sized and small ships, it is less effective on large ships, and Although it would be theoretically possible to reduce the shaking by intentionally reducing the ship's stability at the expense of its stability, in reality this would be extremely dangerous. According to IIIJ, this is an unavoidable negative point compared to the aforementioned ships that navigate underwater.
In theory, even if a ship sailing on the surface of the water were to be submerged while sailing, it would lose its buoyancy, and once it unexpectedly began to sink, it would continue to sink until it settled on the ocean floor. be.

In addition, stability can be maintained with respect to side-to-side rolling by placing the center of buoyancy above the center of gravity, but with pitching, the front and rear hulls may turn half a turn in the longitudinal direction. To deal with this, it is possible to pour or move a small amount of water in the front and rear directions, but due to the inertia of the water, this cannot be done immediately and the cost will be high. There were disadvantages.

Some ships are equipped with hydrofoils 8 to avoid movement on the water surface, but stable navigation is impossible when the water surface becomes rough due to storms, etc., especially when the ship is large. had drawbacks such as a lack of ability to float heavy ships.

On the other hand, modern ships are required to sail at high speeds, and the higher the speed, the greater the propulsion resistance, and the energy generated by the high-horsepower engines they are equipped with is consumed by this propulsion resistance.

Most of this propulsion resistance is due to resistance to water.

One of the resistances against water is frictional resistance, and the other is wave resistance.

When the sailing speed is low, the wave-making resistance is small and frictional resistance accounts for most of it, but as the sailing speed increases, the wave-making resistance increases at an accelerating rate, and most of the energy used is It is spent on wave-making resistance.

The purpose of this invention is to solve the advantages and disadvantages of surface navigation, the advantages and disadvantages of submerged navigation, and the problems of ships that could not combine the advantages of both based on the above-mentioned prior art. An excellent constant-depth semi-submersible surface-navigating vessel that combines the advantages of the two through a rational and simple structure, and which benefits the field of ocean navigation application in the transportation industry. It is intended to provide structure.

Means and operation for solving the problems> In accordance with the above-mentioned object, the structure of the present invention, which is summarized in the claims of the above-mentioned patents, is such that the main body of a ship sailing on the water surface is located above the water line of the water surface. The submersible front hull is submerged under the water surface with low wave-forming resistance, and the two are connected through the ship body by a water cutter with low water flow resistance, and the water cutter maintains a minimum preliminary buoyancy. As the reserve buoyancy changes due to external forces such as waves, wind, and the turning force of the ship, horizontal rudders installed at the front and rear of the submersible front hull are controlled by computer-controlled operations, etc., so that the ship can maintain a constant depth. The space on the main body of the ship should be increased as much as possible to make the passenger cabin large, and cargo could be loaded efficiently, and the propulsion system should be The engine is popular as an engine that can use oxygen, such as a steam engine or an internal combustion engine.The engine is designed to be able to consume enough oxygen, and to be able to exhaust air smoothly, so that its function as a surface vessel is different from that of conventional engines. It is exactly the same as a ship, and uses technical measures to ensure stable navigation in all weather conditions by adjusting the buoyancy of the submersible front hull using the horizontal rudder.

<Embodiment - Configuration> Next, an embodiment of the present invention will be described below based on the drawings.

In the basic embodiment shown in Fig. 1.2, 1 is a submersible front hull, and in this embodiment, it is formed in a dare drop type, and side rudders 5.
. . . are capable of freely tilting forward and backward in the vertical direction, and are made operable by an appropriate drive device controlled by a computer.

In addition, WL-1 and WL-2, including this embodiment, respectively show the levels of the submersible front hull 1 in a floating state and a submerged state with respect to the water surface. It is shown relative to the front hull 5.

In the embodiment shown in Fig. 3.4, the above-mentioned submersible navigation is carried out via a pair of water cutters 3.3 formed so that the ship body 2 is located above the water surface to reduce water flow resistance to the water surface. The hull 1.1 is mounted on the lower stage in a one-to-one unit.

As shown in FIG. 3, when increasing the strength of the connection, the water cutters 3 are V-shaped cutters 3' and 3', respectively, as shown by dotted lines.
It is also possible to set it as

In addition, as shown in Fig. 4, inside the vessel body 2 there are water tanks,
It is also possible to adopt an embodiment in which the water injection part 4 is formed in a seawater tank or the like.

Further, in the embodiment shown in Fig. 5.6, a suspension body 9 is separately provided between the water cutter body 3.3 at the rear of the ship body 2 (a vertical rudder 6 is provided, and the suspension body 9 is installed separately and serves as a propulsion device). Necessary in embodiments equipped with propeller 7.

<Embodiment - Effect> Then, the effect of the structure of the embodiment shown in Fig. 3.4 will be explained based on Fig. 7.8. First, the submersible front hull shown in Fig. 7 will be explained. 1 is submerged below the water surface and is sailing at a level indicated by Wl -2, and when a longitudinal wave, that is, a wave W-1, approaches relatively, a buoyant force of +B is applied to the front part of the cutter body 3. increases, and the buoyancy of the increase is 10B
In response to this, all transverse rudders 5' of the submersible front hull 1 are tilted forward and downward to form a working force -', thereby
The depth to the water surface WL-2 at the front part of the cutter body 3 is kept unchanged, and waves W-
2 comes relatively to the rear and becomes W-2 as the ship moves forward, the buoyancy decreases by -8 at the rear of the water cutter 3, and the buoyancy on the rear side opposite to the lowered buoyancy is reduced. The buoyancy force of the rudder 5'' is applied by 10F, thereby maintaining the depth of the rear part of the water cutter 3 relative to the water surface W-2 unchanged.

In this case, the vertical direction control of the side rudders 5', 5' in response to the increase in the wind force applied to the channel body 3 is controlled by an appropriate wave detection device installed on the ship. The turning movement can be controlled in real time as the wave W-LW-2 approaches the wave W-LW-2. Similarly, ff
1lJ Utl can be done.

Therefore, the pitching of the ship in the longitudinal direction, that is, the longitudinal direction, is completely eliminated, the depth with respect to the water surface WL-2 is kept constant, and the ship sails with the horizontality in the longitudinal direction kept stable.

Therefore, for the low 1 song target shown in Figure 8, waves rise from the left side of Figure 8, that is, from the port side, and the waves rise from the starboard R side.
When a valley is formed on the side, a buoyancy of +B' is applied to the port side, a buoyancy of -B' is reduced to the starboard R side, and furthermore, as shown in the figure, wind W is applied from the starboard R side. and when the rudder body turns to the right, an increase in buoyancy of +B' on the port side,
Also, a buoyancy reduction of -B' is applied to the starboard R side, or the transverse rudder 51 on the port side is turned downward and the buoyancy is reduced to 10 B'.
The sinking cars F' and -F' corresponding to
, -B', so as to form a floating force F'+F'' corresponding to -B', so that each groove rudder 5 is
', 5'' always maintains the set depth with respect to the water surface W+--2, so it is possible to maintain a horizontal state and navigate in a stable attitude without rolling.

The embodiment shown in FIG. 9.10 is a ship for transporting cargo, and the upper part of the ship body 2 carries predetermined cargo 8.8...
is placed, and a pair of left and right draining bodies 3.3 are placed as in the above-mentioned embodiment.
One submersible front hull 1.1 is connected to each of the submersible front hulls 1.1, each of which is provided with a water injection part 4.4 in the longitudinal direction and has a side rudder 5.4 in the longitudinal direction.
5' is provided, a propeller 7 is provided as a propulsion device, and a longitudinal rudder 6 is provided, and
In the embodiment shown in FIG. 11, a pair of water cutters 3.3 are extended downwardly on the left and right sides of the ship body 2, and two submersible front hulls 1.1 are provided at the lower ends of the two, and a total of four Submersible front hull 1.1
... are provided, and the side rudders 5' and 5 are respectively provided.
'', and the rear submersible front hull 4 is provided with a propeller 7 as a propulsion device and a vertical rudder 6.However, none of these have any effect on the above-mentioned embodiments and their effects. There is no change, but against external forces such as waves in the longitudinal direction, waves in the lateral direction, wind power, and turning force, the ship is controlled by computer detection and control. The main body 2 is always kept at a constant height with respect to the water surface, and each submersible front hull 1 is kept at a constant depth so that the vessel can always sail horizontally.

It should be noted that the embodiments of this invention are of course not limited to the above-mentioned embodiments, and three or more can be provided for the water cutter and the submersible front hull connected to the lower end thereof.
Moreover, various aspects can be employed, such as the ability to provide three or more side rudders for each submersible front hull.

Moreover, it goes without saying that the structure can be applied not only to large ships sailing on the open sea, but also to small and medium-sized ships sailing in coastal waters.

<Effects of the Invention> As described above, according to the present invention, basically, even if the buoyancy of a ship navigating in the open ocean or near sea changes in response to external forces such as waves, wind force, and turning of the ship, the amount of change is By forming the ditch body so that the lifting force is less than that of the side rudder installed on the submersible front hull, the vessel can always sail horizontally and stably within the above conditions. Therefore, not only rolling but also pitching is prevented, and cargo and passengers can be transported in a stable state. Waves that rise and fall in relative proximity and the rise and fall of the ditch body are automatically detected by appropriate sensors and processed by a computer, and the transverse rudder installed in the fore-and-aft direction of the submersible front hull is tilted upward or downward. It has the advantage of being able to apply lifting force in real time to keep the ship in a stable horizontal state at all times, even before buoyant forces such as waves are applied to the ship's hull. The effect is produced.

In addition, since the side rudder is installed underwater, the higher the speed the ship travels, the greater the buoyancy and sinking force it can provide, so even when the sea is open to the open sea or the sea is rough. , Qin has the excellent effect of guaranteeing stable navigation.

In addition, since the main body of the ship can be installed above the water surface via a water cutter with respect to the side rudder, it is possible to freely obtain propulsive force from an internal combustion engine that uses atmospheric oxygen, or a steam engine. It is possible to take full advantage of the usual advantages of a surface-going vessel, and it is also possible to always have the necessary minimum reserve restoring force, ensuring a stable posture not only mentally but also structurally. The excellent effect of being able to do this is achieved.

Since the ship itself can be installed above the water surface, it does not need to have a streamlined hull like a high-speed ship, which allows for a large amount of space and the ability to carry a large amount of cargo and a large number of passengers. In addition, the excellent effect of reducing wave-making resistance during high-speed navigation and improving energy efficiency is achieved.

As a result, the cost benefits of merchant ships, etc. could be increased, and this would be a invasive effect in terms of cost and economy.

Detailed Description of the Invention (Field of Industrial Application) The disclosed technology belongs to the field of structural technology for ships, including extremely large ships that can sail not only near the coast but also on the open ocean. Summary of the gist> Therefore, the present invention is equipped with a side rudder that enables vertical, forward, and backward tilting movements of the hull with respect to the water surface, not only in the submerged state but also in the floating state.

This invention relates to the structure of a water-navigating ship having a propulsion device such as a longitudinal rudder and a screw, and particularly relates to the structure of the water cutter, in which the buoyancy of the water cutter is caused by waves, wind, or turning during sailing. If it changes due to centrifugal force, etc.
This invention relates to a constant-depth semi-submersible surface-navigating vessel structure formed such that the amount of change is less than the flotation capacity or sinking capacity of side rudders provided below the water surface at least at the front and rear of the submersible vessel. <Prior art> As is well known, common activity areas include land, water, and
There are three types of air: land is the place for activities of land animals such as running, air is the place for birds to fly, and underwater is the place for the lust of fish. Birds are active both in the air and on the ground, some fish are active both in the water and in the air, and mammals are active both in the air and in the air. Humans, who developed as humans, began to operate through the technical means of ships in the 1 meter of water between underwater and air. Historically, from ancient bowl ships to modern giant ships, ships have been formed into a bowl shape to reduce resistance to water flow, and the buoyancy of the water that has been removed has been used to eliminate water. The ship floats on the surface of the water and remains 1 meter above the water, allowing it to retain reserve buoyancy and maintain the ability to recover even if the ship is tilted.As a propulsion device, a gourd, a pole, or wind power is used. In modern times, they were propelled by mechanical forces such as propellers, but the principle remains essentially unchanged to this day. However, the appearance of deep-sea Pj1 and submarines in the early modern period, which were capable of navigating submerged underwater, was a revolutionary technological development for vessels that navigated only on the surface of the water. However, a nuclear-submerged vessel requires a long submersion time, and conventionally, the energy provided by storage batteries, etc. is limited over time, and even submarines equipped with so-called snorkels have a limited ability to operate submerged for long periods of time. However, with the recent use of nuclear power, it has become possible to operate for an infinitely long time over time, or it has become difficult to handle and economical due to the constraints of operating under conditions that are dangerous to the reactor and its peripheral equipment. The disadvantage was that it was not worth it. Therefore, among commercial ships whose commercial base cannot be ignored, ships that navigate on water have been used for a long time. Naturally, surface-going vessels are equipped with propulsion engines that require oxygen from the atmosphere, which poses the following problems. In other words, pitching and rolling are extremely unpleasant phenomena for ships that navigate while floating on the surface of the water, and even though we know that pitching and rolling guarantee the ship's resilience, we are mentally unable to do so. In addition, it is emotionally unstable while sailing, and it is not possible to deal with this by installing stabilizers on medium-sized and small ships, but it is unlikely to be effective on large ships. Although it is theoretically possible to reduce the shaking by sacrificing the stability performance and intentionally reducing the restorability of the vehicle, in reality it is extremely dangerous, and this point is explained above. Of course, there are unavoidable disadvantages compared to a ship that navigates underwater in a submerged state, but theoretically even if a ship that sails on the surface of the water were to sail in a submerged state, it loses buoyancy and once If it starts to sink unexpectedly, it will sit on the ocean floor and continue to sink. Also, for side-to-side rolling, is it possible to maintain stability by placing the center of buoyancy above the center of small force? For pitching, for example, the ship's front and rear hulls rotate half a turn in the direction of the longitudinal force. In order to deal with this situation, it is possible to consider pouring a small amount of water in the front and rear directions or slowing the movement, or to prevent this from happening due to the phylogenetic nature of water. However, some ships have built underwater holes to avoid turbulence on the water surface, but if the water surface is rough due to storms, it will be difficult to maintain stability. It was impossible to navigate, and especially when ships became large, there were drawbacks such as a lack of ability to float heavy ships.On the other hand, modern ships are required to sail at high speeds, and It is true that the propulsion resistance becomes so large that the energy generated by the equipped high-horsepower engine is consumed by this propulsion resistance.Most of this propulsion resistance is due to resistance to water.Water One of the resistances to water is frictional resistance, and the other is wave-making resistance.When the sailing speed is low, the wave-making resistance is small and is mostly just the friction resistance, but when the sailing speed is high, the wave-making resistance is small. When this happens, the wave-making resistance increases at an accelerating rate, and most of the energy used is inevitably spent on the wave-making resistance. Disadvantages, and the advantages and disadvantages of submerged navigation, as well as the problems of ships that could not incorporate only the advantages of both, are considered technical issues to be solved, and a rational and simple structure is developed. By combining only the advantages of both, we aim to provide an excellent constant-depth semi-submersible surface-navigating vessel structure that is beneficial to offshore navigation application fields in the transportation industry. In accordance with the above-mentioned object, the structure of the present invention, which is summarized in the scope of the above-mentioned claims, is such that the main body of a ship sailing on the water surface is positioned above the water line of the water surface so that it can be lowered below the water surface. The submersible hull is placed in a submerged state with low wave-making resistance, and the two are connected through the ship body by a water cutter with low water flow resistance, and the water cutter maintains a minimum reserve buoyancy, and the reserve buoyancy is The horizontal rudders installed at the front and rear of the submersible front hull are controlled by computer-controlled operations in response to changes in external forces such as the wind and the turning force of the hull, and the ship maintains a constant depth while navigating. The space on the ship body is made as large as possible to increase the winter solstice, and cargo can be loaded efficiently, and the propulsion engine is replaced by a steam engine or an internal combustion engine. As an engine that can use oxygen, it will be able to consume oxygen in the atmosphere into light, and exhaust will be carried out smoothly, and its functions as a water surface vessel will be exactly the same as a general conventional vessel. This is due to the technical measures taken to ensure stable navigation in all weather conditions by adjusting the buoyancy of the submersible front hull using the horizontal rudder. <Embodiment - Configuration> Next, an embodiment of the present invention will be described below based on the drawings. In the basic embodiment shown in Fig. 1.2, 1 is a submersible front hull, and in this embodiment, it is formed in a dare drop type, and side rudders 5.
. . . are each capable of vertically tilting forward and backward movements, and are made movable by appropriate computer-controlled drive necks. Incidentally, WL-1 and WL-2, including this example, respectively indicate the levels of the floating state and submerged state of the submersible front hull 1 with respect to the water surface, but for convenience of illustration, the submersible front hull 1 The figures are relative to 5. In the embodiment shown in Fig. 3.4, the vessel main body 2 is placed above the water surface, and the water flow resistance against the water surface is reduced through a pair of water cutters 3.3 formed of small pieces. The submersible hull 1.1 is mounted on the lower deck in a one-to-one unit. As shown in FIG. 3, when increasing the strength of the connection, the water cutters 3 are V-shaped cutters 3' and 3', respectively, as shown by dotted lines.
It is also possible to provide it as In addition, as shown in Fig. 4, inside the vessel body 2 there are water tanks,
It is also possible to adopt an embodiment in which the water injection part 4 is formed in a seawater tank or the like. In addition, in the embodiment shown in FIG. 5.6, a suspension body 9 is provided separately between the cutter body 3.3 at the rear of the ship body 2, and the vertical rudder 6 is
This embodiment is equipped with a propeller 7 as a propulsion device. <Embodiment - Operation> The operation of the structure of the embodiment shown in Figure 3.4 will be explained based on Figure 7.8. First, the submersible front hull shown in Figure 7 will be explained. 1 is submerged in the water surface and the water surface is at the level indicated by WL-2, and when longitudinal waves, waves, and waves W-1 come relatively close to each other, the water cutting body 3
A buoyant force of 10 B increases at the front of the submersible front hull 1, and in response to the increased buoyancy of 10 B, the transverse rudder 5' at the front of the submersible front hull 1 is tilted forward and downward to form a descending car F. The depth to the water surface WL-2 at the front part of the water cutter 3 is kept unchanged, and the wave W-2 is prevented from changing at the rear of the water cutter 3 as the ship moves forward.
When the ship becomes relatively rearward and becomes W-2 as the ship moves forward, the buoyancy decreases by -B at the rear of the water cutter 3,
The buoyancy force of the rear transverse rudder 5'' is applied by 10F against the reduced buoyancy force -B, thereby maintaining the depth of the rear part of the water cutter 3 relative to the water surface W''-2 unchanged. In order to control the vertical direction of the side rudders 5' and 5' in response to increases and decreases in the wind force applied to the channel body 3, the turning movement of the groove rudders 5' and 5' is accurately controlled by an appropriate wave detection device mounted on the ship. It is possible to operate RTL++ in real time in the vicinity of waves W-LW-2, and this not only counters the 1t or 2 reduction in the j?iQ force of the water cutting body 3 due to waves, but also the External forces such as turning forces can be controlled in the same way. Therefore, the pitching of the ship in the longitudinal direction, that is, the longitudinal direction, is completely eliminated, the depth to the water surface WL-2 is kept constant, and the longitudinal Navigation is carried out with the levelness of the direction stable. Therefore, regarding the rolling image shown in Figure 8, waves are rising from the left side of Figure 8, that is, waves are rising on the port side, and waves are rising on the starboard R side. When the valley is formed, a buoyant force of +B' on the port side also increases.
A buoyancy reduction of -B' is performed on the starboard R side, and furthermore, when wind W is applied from the starboard R side as shown in the figure, and when the rudder body turns to the right, a +B' buoyancy reduction is performed on the port side. The buoyancy increase will be applied to the starboard R side, and the buoyancy reduction of -B' will be applied to the starboard R side.
The sinking car F', -F" corresponding to 3' is applied, and the buoyant force -B' is reduced for the side rudder 5"' at the left limit R.
, -B'' to form a levitation force F'10F', and therefore each side rudder 5
``, 5'' always maintains the set depth with respect to the water surface WL-2, so it is possible to maintain a horizontal state and navigate in a stable attitude without rowing. Also, as shown in Figure 9.10. The embodiment is a ship for transporting cargo, and a predetermined cargo 8.8...
is placed, and a pair of left and right draining bodies 3.3 are placed as in the above-mentioned embodiment.
A submersible front hull 1.1 is connected to each of the submersible front hulls 1.1, each of which is provided with a water injection part 4.4 in the longitudinal direction and has a transverse rudder 5' in the longitudinal direction.
, 5' are provided, a propeller 7 as a propulsion device is provided, and a vertical rudder 6 is also provided.
In the embodiment shown in FIG. 11, a pair of water cutters 3.3 are extended downwardly on the left and right sides of the ship body 2, and two submersible front hulls 1.1 are provided at the lower ends of the two, and a total of four Submersible front hull 1.1
... are provided, and the side rudders 5' and 5 are respectively provided.
'', and the rear submersible front hull 4 is provided with a propeller 7 as a propulsion device and a longitudinal rudder 6, but there is no difference in operation and effect from each of the above-mentioned embodiments. In response to external forces such as longitudinal waves, lateral waves, wind force, and turning force, the ship is controlled by computer detection and control by marking the lifting force against the buoyancy that increases and decreases due to the turning operation of each side rudder. The main body 2 is always kept at a constant height with respect to the water surface, and each submersible front hull 1 is kept at a constant depth, so that the vessel can always sail in a horizontal state. Of course, this is not limited to the above-mentioned embodiments, and it is possible to provide three or more submersible front hulls connected to the water cutter and its lower end, and each submersible front hull For the hull, it is possible to adopt a forepost configuration in which three or more side rudders can be installed.Also, this structure can be applied not only to large ships sailing on the ocean, but also to small and medium-sized ships sailing in nearby waters. <Effects of the Invention> As described above, according to the present invention, basically, the buoyancy of a ship sailing in the open sea or near sea changes in response to external forces such as waves, wind power, and turning of the ship. However, the amount of change is less than the lifting force of the transverse rudder installed on the submersible hull, so the cutter is formed so that within the range of the above conditions, the ship will always remain horizontal and stable. It has the excellent effect of being able to navigate, thus preventing not only rolling but also pitching, and being able to transport cargo and passengers in a stable condition. Waves moving up and down in relative proximity to the ditch body and the elevation of the ditch body are automatically detected by appropriate sensors and processed by a computer, and the transverse rudder installed in the fore-and-aft direction of the submersible hull is turned upward or downward. Since it is possible to apply a lifting force by tilting the ship in the opposite direction, the lifting force can be applied in real time before the buoyancy force of waves etc. is noticed on the ship, and the ship can always be kept in a stable horizontal state. In addition, since the horizontal rudder is installed underwater, the faster the ship travels, the greater the buoyancy force and sinking horns can be applied to it. This has the excellent effect of ensuring stable navigation even when the sea is rough.Also, since the main body of the ship can be installed above the water surface with respect to the side rudder via the water cutter. Propulsion from an internal combustion engine using atmospheric oxygen or a steam engine can be freely obtained, making it possible to take full advantage of the usual advantages of a surface-going vessel, and with the minimum necessary reserve. It has the excellent effect of ensuring a stable posture, not only mentally, but also structurally. Furthermore, since the ship body can be installed above the water surface, it does not need to have a streamlined hull like high-speed ships, which allows a large space to be secured and allows for the transportation of large amounts of cargo and large numbers of passengers. In addition, it has the excellent effect of reducing wave-making resistance during high-speed navigation and improving energy efficiency. Therefore, it is possible to increase the cost advantage of commercial ships, etc., and the excellent effect of being financially compatible is achieved. 4.
