Description

Leisure boat for underwater viewing {leisure boat for viewing underwater}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leisure boat for underwater viewing and, more particularly, to a leisure boat for underwater viewing with improved stability in the lateral direction due to improved lateral stability of the ship.

In general, as marine leisure culture is developed, many people enjoy marine leisure by looking for sea or river to enjoy marine leisure, and various marine leisure equipment are being developed accordingly.

Here, marine leisure culture, which has been concentrated on water leisure using conventional yachts and boats, is becoming a marine leisure culture for underwater viewing that can experience and experience underwater. Such ships that can be watched are the sightseeing submarine, the glass boat under the hull and the semi-submersible boat. Here, the submarine can be submerged in the water, so the passenger can watch the water. In addition, a transparent glass is mounted on the bottom of the ship so that the underwater boat can observe the underwater. The semi-diving boat floats on the water like a regular boat, and the hull is extended toward the water, and a transparent window is installed on the port side of the hull, which is submerged in the water.

On the other hand, the ship is classified according to the number of hulls, and a ship having one hull is called a mono hull, and most ships follow this form. In addition, a ship with two hulls is called a catamaran, and its relative resistance is higher than that of a single-wire system, so that it is aimed at stable operation rather than speed. In addition, a vessel with three hulls is called a trimaran, and a secondary hull is installed on both sides of the central hull so that the most stable operation can be carried out. Various methods have been applied.

However, the semi-submersible boat has a problem in that the passengers inside the hull which are submerged in the water under the influence of the wave on the water surface and the influence of the current below the water surface feel relatively nausea or can not watch the water smoothly due to the rocking motion .

In addition, the semi-submersible boat has a problem in that, when a rollover occurs due to rocking, the passengers aboard the inside of a hull which is submerged in water are difficult to quickly come out to the surface of the water, resulting in lower safety.

Therefore, there is an urgent need to develop a semi-submersible boat for improving its structure so that the shaking motion of the ship is minimized and the stability of the ship is improved.

1 to 5, an underwater viewing leisure boat 100 according to an embodiment of the present invention includes a main hull 10, a secondary hull 20, a main tank 30, an auxiliary tank 40, A wave height sensing unit 50, a ballast water control unit 60, and a control unit 70.

Here, the main hull 10 includes an underwater viewing portion 10a and a deck portion 10b. In detail, the underwater viewing part 10a is formed with a first boarding space in which an occupant can ride, and on the outer surface of the underwater watching part 10a, a passenger boarded in the first boarding space can view A projection window 11 may be formed in which an external projection is made. The underwater auditorium 10a may be provided with a control board or the like capable of controlling the underwater viewing leisure boat 100, or may be provided with a seat on which the passenger can sit.

In addition, the deck portion 10b is provided on the underwater viewing portion 10a. In detail, the deck portion 10b is symmetrical with the port and starboard forms buoyancy, and the lower end portion is connected to the upper portion of the underwater viewing portion 10a. Accordingly, the underwater viewing part 10a can be maintained in a submerged state with the deck part 10b floated on the water surface.

In the upper portion of the deck portion 10b, a second boarding space in which a passenger can enjoy leisure in the water can be formed. At this time, the deck portion 10b may have an opening / closing portion that is selectively opened and closed so that the first boarding space and the second boarding space are communicated with each other. That is, the occupant can selectively move to the first boarding space and the second boarding space through the opening and closing part.

Here, the auxiliary hulls 20 are disposed in pairs so as to be mutually symmetrical on both sides in the width direction of the main hull 10. In detail, the auxiliary hull 20 includes a first auxiliary hull 20a disposed on one side in the width direction of the main hull 10 and a second auxiliary hull 20b disposed on the other side in the width direction of the main hull 10, ).

The first auxiliary hull 20a and the second auxiliary hull 20b may be formed to correspond to each other and the bottom of the deck 10b may correspond to a waterline of the deck 10b, And to the port and starboard of the unit 10b, respectively. Here, the waterline is preferably understood as a line where the hull meets the water surface. Thus, the bottoms of the auxiliary hulls 20a, 20b and the deck portion 10b can be immersed in water at the same time of launching.

A buoyancy member may be provided inside the first auxiliary hull 20a and the second auxiliary hull 20b to form buoyancy. At this time, the buoyancy member may be provided with an air tank or the like. The auxiliary hull 20 can provide buoyancy to both sides of the main hull 10 so that the deck portion 10b connected to the underwater viewing portion 10a is suspended over the water surface.

Meanwhile, the main tank 30 may be provided below the main hull 10. In detail, the main tank 30 is provided on the lower side of the first boarding space, that is, below the underwater viewing unit 10a. Here, the main tank 30 may be formed to have a width and a length corresponding to the bottom portion of the underwater viewing portion 10a and cover the entire bottom portion of the underwater viewing portion 10a.

At this time, a first water storage space in which the ballast water (bw in FIG. 3A) is stored is formed in the main tank 30. Here, the equilibrium (bw) is preferably understood to be the sea water in which the underwater viewing leisure boat 100 is floated. When the predetermined amount of the balanced water bw flows into the main tank 30, the center of gravity of the main hull 10 is formed such that the submerged state of the underwater viewing unit 10a is stably maintained .

In addition, the center of gravity of the main hull 10 can be adjusted according to the amount of the water stored in the main tank 30. That is, as the amount of water stored in the main tank 30 increases, the center of gravity of the main hull 10 may be lowered. At this time, as the center of gravity of the main hull 10 is formed lower, the up-and-down movement caused by the crest can be attenuated.

Here, when the predetermined amount of the balanced water bw flows into the auxiliary tank 40, the bottom of each of the auxiliary hulls 20a and 20b may be kept immersed in the water to a predetermined depth.

At this time, the transverse restoring force (heeling moment) of the main hull 10 can be adjusted according to the amount of water stored in the auxiliary tanks 40a and 40b. Here, the transverse restoring force refers to a force to return to the initial state in which the transverse rolling yarn is removed in the rolling motion of the main hull 10 in the width direction due to the influence of waves or the like.

The center of gravity of each of the auxiliary hulls 20a and 20b may be formed to be lower as the amount of the water stored in the auxiliary tanks 40a and 40b increases. At this time, when the center of gravity of each of the auxiliary hulls 20a and 20b is lowered, the angular size of the crossbars directed toward one side or the other side in the width direction decreases as the main hull 10 rotates in the width direction of the main hull 10, So that the lateral restoring force can be increased.

Accordingly, when the water storage amount of the equilibrium water (bw) of each of the auxiliary tanks 40a and 40b is increased, the main hull 10 increases the lateral restoring force, minimizing accidents such as overturning of the hull in an external environment with high digging Stable operation is possible. Further, the main hull 10 can be prevented from being directly transmitted by the auxiliary hulls 20a and 20b, such as the impact of a wave, so that the wave resistance can be improved.

Meanwhile, the wave height sensing unit 50 is provided at one of the main hull 10 and the auxiliary hull 20. The crest sensing unit 50 may measure the crest of the ocean in which the main hull 10 is floated and may be connected to the control unit 70 in a wireless manner to detect the detected peak value, Lt; / RTI >

The ballast water control unit 60 may be installed inside the main hull 10 and may be connected to the main tank 30 and the auxiliary tank 40. In detail, the ballast water control unit 60 may include a pump for sucking and discharging seawater. At this time, the pump included in the ballast water control unit 60 is connected to the control unit 70, and sucks and discharges the seawater in accordance with the driving control of the control unit 70.

The ballast water control unit 60 includes a first ballast water line 65b connected to the main tank 30, a second ballast water line 65c connected to the first auxiliary tank 40a, And the third ballast water line 65d connected to the second auxiliary tank 40b to distribute and supply the seawater sucked from the ocean as the ballast water bw. Accordingly, the ballast water control unit 60 is selectively driven under the control of the controller 70 to adjust the water storage amount of the ballast water bw of the main tank 30 and the auxiliary tank 40 have.

The first ballast line 65b, the second ballast water line 65c and the third ballast water line 65d are provided with a first solenoid valve connected to the control unit 70 and selectively opened and closed It is possible. The respective first solenoid valves are selectively opened and closed under the control of the controller 70 in the main tank 30 and the auxiliary tanks 40a and 40b so that the inflow amount of the ballast water bw May be individually adjusted.

Meanwhile, the controller 70 receives power from a power storage device such as a battery and selectively supplies power to the wave height sensing unit 50 and the ballast water control unit 60. The controller 70 receives the wave height measurement value from the wave height sensing unit 50 and controls the operation of the balance water level controller 60 according to the wave height measurement value.

6 is a flowchart illustrating a method of controlling a leisure boat for underwater viewing according to an embodiment of the present invention.

As shown in FIG. 6, the control method of the leisure boat 100 for underwater viewing according to an embodiment of the present invention proceeds as follows.

3A to 6, the leisure boat 100 for underwater viewing is installed in the main tank 30 and the auxiliary tank 40 in a marine having a height h1 of less than a predetermined reference value, The equilibrium water bw may be stored so as to correspond to a predetermined minimum water level (m in FIG. 5) so that a predetermined center of gravity G1 is formed.

Here, the control unit 70 receives the wave height measurement value from the wave height sensing unit 50 (s10). In detail, the wave height sensing unit 50 measures the wave height of the ocean in which the underwater viewing leisure boat 100 is floating, and automatically outputs the wave height measurement value to the control unit 70 in accordance with a predetermined time interval. Can be transmitted. Of course, in some cases, the wave height sensing unit 50 may manually measure the wave height of the ocean so as to correspond to the operation of the user and transmit the wave height measurement value to the controller 70.

Then, it is determined whether the peak value received from the peak-sensing unit 50 exceeds a preset peak value (s20). At this time, the digging reference value may be variously set according to the load or design of the underwater viewing leisure boat 100. For example, if the peak value is set to 2 m, the controller 70 determines whether the peak value received from the peak value sensing unit 50 exceeds 2 m.

If the measured peak value received from the peak sensing unit 50 exceeds a preset reference value (s20), the safe operation mode is activated and the balance tank 30 and the auxiliary tank 40 are connected to the equilibrium water- (bw) is supplied (s21).

3B to 6, a wave height h2 exceeding a predetermined wave height reference value is generated during operation due to a change in the ocean or the like, and the control unit 70 receives the wave from the wave height sensing unit 50 The safe navigation mode is activated if it is determined that the measured peak value exceeds a predetermined peak value.

At this time, the control unit 70 may control the output monitor unit provided in the first boarding space to display whether the safe operation mode is activated in real time. Accordingly, the passenger who has confirmed the activation of the safe operation mode can recognize the floating state of the floating sea and can operate with the alert.

The control unit 70 activates the safe operation mode and controls the ballast water control unit 60 to be driven. At this time, the pump provided in the ballast water control unit 60 is powered by the control unit 70 and can be driven so that the sea water is immediately sucked through the suction line 65a.

The control unit 70 controls the first solenoid valves provided in the ballast lines 65b, 65c and 65d to be opened and the seawater sucked by the pump provided in the ballast water control unit 60 (65b, 65c, 65d) to be distributed and supplied as the ballast (bw).

3b, the main tank 30 and the auxiliary tank 40 are supplied with the ballast water bw from the ballast water control unit 60, The first water storage space and the equilibrium water bw at a predetermined minimum water level (m in FIG. 5) in the second water storage space 41 of the auxiliary tank 40 are stored. The center of gravity G2 of the underwater viewing leisure boat 100 is positioned at a predetermined minimum water level m in the main tank 30 and the auxiliary tank 40 so that the ballast water bw is stored The center of gravity G2 may be formed at a position lower than a predetermined center of gravity G1 before the ballast water bw is introduced.

Accordingly, since the center of gravity G2 of the leisure boat for underwater viewing 100 is formed lower than the predetermined center of gravity G1 before the ballast water bw flows in, the main hull 10 and the auxiliary The amplitude with respect to the vertical movement of the hull 20 can be reduced and the floating stability of the hull can be improved. The inflow process of the ballast water bw as described above is instantaneously progressed when the crest value is received in the controller 70. The passenger is automatically controlled by the control unit 70 for a sudden change in the weather condition Immediate contrast is possible.

In addition, the leisure boat 100 for underwater viewing has an increased restoring force even when the wave height h2 exceeding a predetermined reference value from the ocean is increased due to a sudden change in weather conditions, so that it can be prepared against an accident such as abalone Since the ballast water bw is stored immediately in the main tank 30 and the auxiliary tank 40, safety for the passenger can be further improved.

A water level sensor may be provided in the main tank 30 and the auxiliary tank 40 to transmit a sensing signal to the controller 70 when the water level is sensed. At this time, each level sensor may be disposed at a position corresponding to the maximum limit level of the main tank 30 and the auxiliary tank 40. The control unit 70 stops the operation of the ballast water control unit 60 when the sensing signal is received from each level sensor in a state where the ballast water control unit 60 is activated by activating the safe operation mode. .

The control unit 70 stops the supply of the ballast water bw to the main tank 30 and the auxiliary tank 40 when the ballast water bw is stored to correspond to the maximum water level .

If it is determined in step s20 that the safe wave operation mode is activated, it is determined in step s30 that the safe wave operation mode is activated.

In detail, the controller 70 determines whether the safe operation mode is active when the peak value received from the peak-sensing unit 50 is determined to be equal to or lower than a preset reference value. At this time, if the safe operation mode is not activated (s30), the step (s10) in which the peak measurement value is received from the peak sensing unit 50 may be repeatedly performed.

If the safe operation mode is activated (s30), the safe operation mode is deactivated and the ballast water bw stored in the main tank 30 and the auxiliary tank 40 is discharged to the outside (S31).

Here, the state in which the wave height measurement value received from the wave height sensing unit 50 is equal to or less than the predetermined wave height reference value and the safe operation mode is activated means that the wave height of the ocean exceeds the predetermined wave height reference value, . ≪ / RTI > In this case, since the ballast water bw has already been supplied to the main tank 30 and the auxiliary tank 40, the control unit 70 cancels the activation of the safe operation mode, Switch.

The control unit 70 may control the amount of the ballast water bw to be stored in the main tank 30 and the auxiliary tank 40 so that the ballast water bw stored in the auxiliary tank 40 is stored at a predetermined minimum water level m. To be discharged to the ocean.

At this time, the main tank 30 and the auxiliary tank 40 may be provided with separate ballast water discharging means. For example, the ballast water discharging means is provided as a separate discharge pump inside the main tank 30 and the auxiliary tank 40, and the ballast water bw stored in the inside of the main tank 30 and the auxiliary tank 40 under the control of the controller 70, Can be discharged into the ocean.

As the ballast water bw stored in the main tank 30 and the auxiliary tank 40 is drained, the total load of the leisure boat for underwater viewing 100 is reduced, The energy efficiency of the propulsion device, such as a motor that provides the propulsion force to the engine, can be prevented.

Of course, the ballast water discharging means may be provided as an opening / closing device for selectively opening and closing the discharge hole according to the control of the controller 70, so that the ballast water bw may be discharged naturally, 30 and the inside of the auxiliary tank 40 can discharge the ballast water bw.

Here, the water storage space is preferably a concept including the first water storage space formed in the main tank 30 and the second water storage space 41 formed in the auxiliary tank 40 Do. In the present embodiment, the partition member 42 is provided in the auxiliary tank 40 as an example.

Specifically, the partition wall member 42 is provided to have a predetermined thickness and protrudes inside the auxiliary tank 40 to correspond to the height of the second water storage space 41. At this time, the second water storage space 41 is partitioned into a plurality of water storage compartments 41a and 41b by the partition wall member 42. Here, the plurality of partition members 42 may be spaced apart from each other at predetermined intervals along the longitudinal direction of the auxiliary tank 40. Of course, the partition wall members 42 may be arranged in the longitudinal direction and the width direction of the auxiliary tank 40 so that the second water storage space 41 may be divided into a plurality of sections.

In addition, the partition member 42 may be formed with a communication hole 42a through which the respective water storage compartment spaces 41a and 41b communicate with each other. At this time, the communication hole 42a may be formed to have various shapes, sizes, and / or quantities according to the amount of the water stored in the second water storage space 41.

Accordingly, even if the sudden rocking occurs, the leisure boat 100 for underwater viewing can prevent the ballast water bw stored in the second water storage space 41 by the partition member 42 from being thrown to one side at a time So that the inclination of each of the hulls 10 and 20 due to the load can be minimized. In addition, the stored water bw can be uniformly distributed to the respective water storage compartments 41a and 41b through the communication hole 42a.

At this time, it is preferable that the position of the communication hole 42a is set to a predetermined minimum water level m of the auxiliary tank 40 or more. More specifically, when the ballast water discharging means is provided at one side of each of the water storage compartments 41a and 41b, the ballast water bw stored in each of the water storage compartments 41a and 41b flows through the communication holes 42a through the ballast water discharging means.

For example, when the ballast water discharging means is provided at a position at the predetermined minimum water level m or more in one side water storage compartment space 41a, the ballast water bw stored in the other side water storage compartment space 41b flows into the communication hole And then discharged to the ocean via the ballast water discharging means through the ballast water discharging means 42a.

Here, if the position of the communication hole 42a is set to a predetermined minimum water level m of the auxiliary tank 40, even if the ballast water bw is discharged to the ocean through the ballast water discharging means, A water amount may remain so as to correspond to the water level m.

That is, when the ballast water bw is discharged through the ballast water discharging means, the ballast water bw is not discharged via the communication hole 42a below the predetermined minimum water level m And may be stored in the auxiliary tank 40 so as to correspond to the minimum water level m.

5, the auxiliary tank 40 is provided with the partition member 42. However, the auxiliary tank 40 may be formed in the main tank 30 such that the partition member 42 has the structure and the shape described above Respectively.

Accordingly, even if the ballast water bw is automatically discharged during the operation, the leisure boat 100 for underwater viewing can maintain the balance water bw in the main tank 30 and the main tank 30 so as to correspond to the minimum water level m. And the predetermined center of gravity G1 may be formed in the auxiliary tank 40. [ In addition, since the equilibrium water bw is stored in the main tank 30 and the auxiliary tank 40 in a state of being uniformly distributed in the respective water storage compartments 41a and 41b even after the ballast water bw is automatically discharged, The stability can be improved.

On the other hand, the control unit 70 controls the suction and discharge directions of the shaking damping unit 90 according to the received tilt detection value. 4, as the wave direction w of the ocean progresses from the first auxiliary hull 20a toward the second auxiliary hull 20b, the water for leisure boats 100 A wave enters the lower side of the first auxiliary hull 20a and the second auxiliary hull 20b is tilted in the water based on the sea level s.

The control unit 70 determines the direction of suction and discharge of the oscillation damping unit 90 based on the tilt detection value when the tilt sensing value is received from the tilt sensing unit 80.

For example, the inclination detection value is detected as a positive value when the main hull 10 is tilted toward the first auxiliary hull 20a, and the main hull 10 is detected as a positive value when the second auxiliary hull 20b, Direction can be detected as a negative (-) value. At this time, the controller 70 determines whether the inclination detection value is a positive value or a negative value, and determines the suction and discharge direction of the oscillation damping unit 90 so as to correspond to the value.

If the tilt detection value received by the controller 70 is a negative value, the main hull 10 is tilted toward the second auxiliary hull 20b. Therefore, the controller 70 controls the shaking damping portion 90) sucks the marine seawater through the first flow line (93) and discharges the seawater sucked into the second flow line (94).

That is, the control unit 70 determines the tilted direction of the main hull 10 from the inclination detection value, and the shaking damping unit 90 detects the tilted direction of the main hull 10, .

At this time, the first flow line 93 and the second flow line 94 are preferably opened toward the lower side of the auxiliary hull 20. More specifically, the first flow line 93 has one end extending toward the first auxiliary hull 20a and the other end connected to the oscillation damping portion 90, And the other end portion extends toward the second auxiliary hull 20b.

The one end of the first flow line 93 and the other end of the second flow line 94 may extend to open below the respective auxiliary hulls 20a and 20b. That is, the openings of the first flow line 93 and the second flow line 94 may be formed at the lower ends of the respective auxiliary hulls 20a and 20b.

In addition, the nozzle portions 95 and 96 may be provided on the opening side of the opening. That is, a first nozzle unit 95 may be provided at one end of the first flow line 93, and a second nozzle unit 96 may be provided at the other end of the second flow line 94. have.

The plurality of nozzle units 95 and 96 may be disposed at predetermined intervals along the longitudinal direction of the auxiliary hulls 20a and 20b. When a plurality of the nozzle units 95 and 96 are provided, one end of the first flow line 93 and the other end of the second flow line 94 are connected to the nozzle units 95 and 96, respectively. And may extend toward the lower portions of the respective auxiliary hulls 20a and 20b.

Here, each of the nozzle units 95 and 96 may be a variable nozzle, and the inner diameter of the nozzle may be varied under the control of the controller 70. Accordingly, the seawater sucked from the rocking damping unit 90 can be discharged toward the sea of the ocean in a state where the pressure is raised by the nozzle units 95 and 96.

For example, when the control unit 70 controls the rocking damping unit 90 to discharge the seawater of the ocean through the first flow line 93 and discharge the sucked seawater into the second flow line 94 It is possible to perform interlocking control so that the nozzles of the first nozzle unit 95 are opened at the maximum diameter. Accordingly, the inflow amount of the seawater flowing through the first nozzle unit 95 can be increased. The second nozzle unit 96 may be controlled so that the minimum nozzle inner diameter of the second nozzle unit 96 is equal to or smaller than the inner diameter of the second flow line 94. At this time, if the minimum inner diameter of the nozzle of the second nozzle unit 96 is less than the inner diameter of the second flow line 94, the seawater flowing into the second flow line 94 due to the difference in cross- The pressure is increased while being injected into the nozzles of the second nozzle portion 96.

Accordingly, the seawater discharged toward the second nozzle unit 96 of the second auxiliary hull 20b is injected vertically toward the lower side of the second auxiliary hull 20b in an increased pressure state, A lifting force capable of raising the horizontal reference line r of the main hull 10 to correspond to the sea level s can be provided.

Accordingly, when the main hull 10 is tilted to one side by the waves of the ocean, the underwater viewing boats 100 are immediately inclined so that the shaking dampers 90 cancel the wave water pressure of the ocean As the seawater sucked in the forward direction is sprayed, the lateral restoration speed is improved and the stability of the operation can be further improved.

When the main hull 10 is inclined toward the first auxiliary hull 20a, the control unit 70 can control the spraying of the seawater through the first nozzle unit 95 have. In addition, when the seawater flow line connected to the shaking damping portion 90 is formed to extend in the forward and backward directions of the main hull 10, when the shaking damping portion 90 is driven The longitudinal restoring force of the main hull 10 may be improved. That is, the shaking damping unit 90 may provide lateral or longitudinal restoring force to the main hull 10 in correspondence with the seawater flow line arranged to set the discharge direction of the sucked seawater.

Meanwhile, when the safe operation mode is activated, the control unit 70 may perform interlocking control so that the rocking damping unit 90 is driven. That is, the control unit 70 activates the safe operation mode and controls the ballast water control unit 60 to be driven when the measured peak value received from the wave height sensing unit 50 exceeds a preset reference value, The driving of the rocking damping portion 90 can be controlled in conjunction with the control. When the safe operation mode is inactivated, the control unit 70 may control the driving of the rocking damping unit 90 to stop.

Accordingly, when the wave height h2 exceeding the predetermined wave height reference value is formed due to sudden climatic change or the like, the control unit 70 interlocks the ballast water control unit 60 and the rocking damping unit 90 with each other A synergistic effect in which the lateral restoration force and the restoration speed of the main hull 10 are improved at the same time can be provided. Of course, in some cases, the shaking damping unit 90 may be driven by the controller 70 during normal operation in which the safe operation mode is inactivated.
