Description

[0001] The present invention relates to a ship having a variable spoiler,

The present invention relates to a ship having a variable spoiler for using fluid during navigation.

In general, ships are used in various fields such as transportation means for transporting passengers and cargo to destinations, fishing vessels for catching fish and shellfish, and military vessels for military purposes. Such a ship moves in a state of contact with a gas and a liquid, so that a drag acts on the ship. The drag is classified into wave resistance caused by the movement of the ship due to the movement of the waves, form drag affected by the shape of the hull, and frictional resistance caused by gas and liquid . Considering the magnitude of the drag force as 100%, it is known that the residual resistance combined with the wave resistance and the shape resistance is about 15% to 20% and the frictional resistance is about 80% to 85%. In other words, most of the drag acting on the ship is made up of frictional resistance.

This frictional resistance occurs when the ship moves while grasping the gas and the liquid, and acts in the direction of stopping the movement of the ship. In addition, since the frictional resistance occupies most of the drag force acting on the hull as described above, it acts as a major cause of canceling the propelling power for moving the ship.

For example, when a 320,000-ton class vessel is operating at a speed of 16 knots, the amount of fuel consumed per day is approximately 104 tons, of which the amount of fuel consumed per day by friction resistance is known to be 83.2 tons. In terms of the amount of money, the fuel cost per day is about W5.3bn due to the frictional resistance. The frictional resistance is the main cause of the increase in the cost of operating the ship. Has become a management constant.

Accordingly, a method for reducing or utilizing frictional resistance against gas and liquid generated during ship operation has been discussed. For example, when the wind generated at the time of ship operation is directed in the direction of obstructing the ship's operation path, fuel consumption is increased because a higher output is required as the frictional resistance applied to the ship increases. Conversely, when the wind is blowing in the same direction as the ship's direction, it acts as a thrust component, which helps reduce fuel consumption. Therefore, it is necessary to develop a technology that can reduce the cost of operating a ship using the wind acting on the ship.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a ship having a variable spoiler capable of increasing the braking force at the time of braking, or obtaining thrust using wind.

In order to solve the above-described problems, the present invention can include the following configuration.

A ship having a variable spoiler according to the present invention comprises: a hull for navigating a liquid; A sensor unit for sensing a direction of a gas blown into the hull; A spoiler installed on the hull and contacting a gas blowing on the hull; And a variable portion coupled to the spoiler and adapted to vary the spoiler according to the direction of the gas sensed by the sensor portion.

In the vessel having a variable spoiler according to the present invention, the variable portion includes a support mechanism for supporting the spoiler and a support mechanism for supporting the spoiler so that the support mechanism raises the spoiler to increase the contact area of the spoiler And an elevating mechanism for elevating the supporting mechanism.

In the case of a ship having a variable spoiler according to the present invention, when the direction of the gas sensed by the sensor unit is a normal flow from the stern to the bow, the spoiler contacts the positive wind The spoiler can be varied to increase the contact area so that thrust is generated.

In the case of a ship having a variable spoiler according to the present invention, when the direction of the gas sensed by the sensor unit is the forward and reverse stoichiometry from the bow of the hull to the stern, the spoiler contacts the forward wind The spoiler can be varied to reduce the frictional resistance.

In the case of a ship having a variable spoiler according to the present invention, when the direction of the gas detected by the sensor unit is a side air blowing toward the side of the hull, the variable area increases the contact area where the spoiler contacts the side air, The spoiler can be varied.

In the case of a ship equipped with a variable spoiler according to the present invention, when the direction of the gas detected by the sensor unit when the hull is braked is a counter-wind toward the stern from the bow of the hull, The spoiler can be varied to increase the braking force by increasing the contact area to be contacted.

According to the present invention, the following effects can be achieved.

The present invention can be implemented in such a manner that propulsion can be performed with less force by using wind during navigation, thereby contributing to improvement of the performance of the ship.

In the present invention, the braking force is reinforced by using the wind at the time of braking, thereby shortening the braking distance and preventing a safety accident such as a collision from occurring.

Fig.

Referring to FIGS. 1 and 2, a ship 100 having a variable spoiler according to the present invention is intended to improve fuel economy or shorten a braking distance by using fluid generated during a navigation operation. In particular, the ship 100 having the variable spoiler according to the present invention can improve the fuel consumption or shorten the braking distance by changing the spoiler according to the direction of the gas such as the wind. For example, the ship 100 having a variable spoiler according to the present invention may increase the contact area between the spoiler and the gas so as to generate thrust, thereby improving the fuel economy or enhancing the braking force, The distance can be shortened.

for teeth. A ship 100 having a variable spoiler according to the present invention includes a hull 110 for operating a liquid, a sensor 120 for sensing the direction of a gas blown into the hull, a spoiler contacting the hull, (130) and a variable portion (140) that varies the spoiler according to the direction of the gas.

The sensor unit 120 senses the direction of a gas blown into the hull 110. For example, the gas may be wind. The gas may be generated by a natural phenomenon, but may occur artificially as the ship 100 propels it. The gas is blown by a stern wind (W1, shown in FIG. 3) blowing from the stern of the hull 110 towards the bow, and blows from the bow of the hull 110 toward the stern 4), and the wind blowing toward the bow from the stern right side of the hull 110 is a right wind (W3A, shown in Fig. 5), and the wind of the hull 110 6), and a wind blowing from the right side of the hull 110 toward the stern is transmitted to the right side wind W4A (shown in Fig. 7) And the wind blowing from the left side to the stern of the hull 100 is the left side wind (W4B, shown in Fig. 7). The spoiler 130 may have a trapezoidal shape, but the shape of the spoiler 130 is not limited thereto. The spoiler 130 may be formed in any other shape as long as it can generate thrust and braking force using the gas. The variable portion 140 varies the spoiler 130 according to the direction of the gas sensed by the sensor portion 120 so that the area of the spoiler 130 contacting the gas ) Can be increased. For example, varying the spoiler 130 may expand the spoiler 130 to increase the contact area contacting the gas, or reduce the contact area of the spoiler 130 by contacting the gas by folding the spoiler 130 Lt; / RTI >

Accordingly, the ship 100 having the variable spoiler according to the present invention can achieve the following operational effects.

First, in the case of a ship having a variable spoiler according to the present invention, the spoiler 130 may be expanded to increase the contact area of the ship 100 with respect to the gas. Accordingly, the ship 100 having the variable spoiler according to the present invention can save the fuel consumed in the navigation by reinforcing the propulsion force necessary for advancing by using the windwave.

Second, when the ship 100 having a variable spoiler according to the present invention is a reverse wind, the spoiler 130 may be folded to reduce the contact area of the ship 100 with the gas. Accordingly, the ship 100 having the variable spoiler according to the present invention can minimize the additional resistance as the spoiler 130 is mounted.

Third, the ship 100 having the variable spoiler according to the present invention can increase the contact area with the gas by expanding the spoiler 130 when a reverse wind is blown at the same time. Accordingly, the ship 100 having the variable spoiler according to the present invention can increase the braking force by increasing the pressure resistance by the gas, thereby reducing the braking distance.

Hereinafter, the hull 110, the sensor unit 120, the spoiler 130, and the variable unit 140 will be described in detail with reference to the accompanying drawings.

Referring to FIGS. 1 and 2, the hull 110 is operated by a liquid. The hull 110 may float in liquid as buoyancy. For example, the liquid may be steel or seawater. The hull (110) constitutes the body of the ship (100). The hull 110 may be loaded with people or loaded with cargo. Accordingly, the hull 110 can navigate the liquid and move the person and the cargo to another place. The hull 110 is connected to the spoiler 130 through the variable portion 140. Accordingly, the hull 110 can receive thrust or braking force generated from the spoiler 130. The hull 110 receives the thrust, thereby reducing the required horsepower required for the propulsion. The hull 110 receives the braking force to reinforce the braking force, thereby reducing the braking distance.

Referring to FIGS. 1 and 2, the sensor unit 120 senses the direction of a gas blown into the hull 110. For example, the sensor unit 120 may sense the direction of the gas by being connected to the weather vane. The sensor unit 120 may be installed at the stern of the hull 110 to sense the direction of the gas flowing from the stern to the bow as in the case of the positive wind W1. The sensor unit 120 may detect the direction of a gas that is installed on a bow of the hull 110 and flows toward the stern from the bow to the stern like the forward wind W2.

The sensor unit 120 can detect the direction of a gas blowing to the hull 110 such as a right wind W3A, a left windworm W3B, a right windworm W4A, and a left windworm W4B. Accordingly, the sensor unit 120 can determine from which direction the ship 100 is resisted by the blowing gas. The sensor unit 120 may be connected to the variable unit 140 using at least one of wire communication and wireless communication, thereby providing the sensed gas direction information.

Referring to FIGS. 2 to 4, the spoiler 130 is installed in the hull 110. The spoiler 130 is installed in the hull 110 in order to use a gas blown into the ship 100. The spoiler 130 changes the flow of the gas to generate a thrust force or a braking force to the hull 110. For example, the spoiler 130 may control the inclination of the gas in the direction in which the gas is blown, thereby adjusting the size of the contact area contacting the gas, thereby generating thrust or reinforcing the braking force. For example, the spoiler 130 can increase the propulsive force of the ship 100 by the force of the forward wind W1 by making contact with a gas such as the forward wind W1 and the lateral winds W3A and W3B. The spoiler 130 may be formed as a rectangular parallelepiped, but not limited thereto. The spoiler 130 may have a pentagonal shape or a hexagonal shape as long as the spoiler 130 can obtain propulsive force from the base. For example, the spoiler 130 is formed in a trapezoidal shape, so that propelling force can be obtained by using a wind, such as a wind. The spoiler 130 is variably coupled to the hull 110 through the variable portion 140. For example, the spoiler 130 may be deployed as the variable portion 140 operates, so that one side of the spoiler 130 may be positioned away from the hull 110. In this case, the contact area of the spoiler 130 in contact with the gas can be increased. For example, the spoiler 130 may be spaced apart from the hull 110 by being folded at one side away from the hull 110 as the variable portion 140 is operated. In this case, the contact area of the spoiler 130 in contact with the gas can be reduced. The spoiler 130 may be separated from or contacted with the hull 110 through the variable portion 140 composed of four variable mechanisms whose length is increased or reduced. The variable mechanisms may be located individually at the corners of the spoiler 130 and may be operated individually or simultaneously. Accordingly, the spoiler 130 may be deployed to increase the contact area according to the direction of the gas sensed by the sensor unit 120. For example, if the wind blowing to the hull 110 is a positive wind W1, the spoiler 130 may be positioned perpendicular to the wind direction. In this case, the spoiler 130 can be expanded to maximize the contact area as compared to the wind contact at different angles. Therefore, the ship 100 can reduce the required horsepower required for the propulsion by obtaining the maximum thrust F1 (shown in FIG. 3) as compared with the case where the ship 100 is contacted at different angles. For example, if the wind blowing to the hull 110 is the forward wind W2, the spoiler 130 may be positioned parallel to the wind direction. In this case, the spoiler 130 may be folded to minimize the contact area. Accordingly, the ship 100 can minimize the increase in resistance due to the attachment of the spoiler 130.

The spoiler 130 may also be deployed in the wind other than the above-described wind to obtain a thrust for moving in a direction other than the straight forward direction. A plurality of spoilers 130 may be installed on the hull 110. For example, the spoiler 130 may be located at various positions, such as a residence, a residence side, a side of the hull 110, as well as a stern and a bow of the hull 110. In this case, the ship 100 can obtain a higher thrust or a higher braking force as compared with a case where only one spoiler 130 is installed by increasing the contact area contacting the gas.

Referring to FIGS. 2 to 7, the variable portion 140 connects the hull 110 and the spoiler 130. One end of the variable portion 140 is connected to the spoiler 130 and the other end is connected to the hull 110. Accordingly, the variable portion 140 can transmit thrust or braking force received by the spoiler 130 to the hull 110. One side of the variable portion 140 is rotatably coupled to the spoiler 130. For example, one side of the variable portion 140 may be rotated by being hinged to the spoiler 130. The variable portion 140 is positioned at each corner of the spoiler 130 formed as a rectangular parallelepiped. For example, the variable portion 140 may include four variable mechanisms and may be divided into four portions of the spoiler 130 to couple the spoiler 130 and the hull 110 together. The variable unit 140 is connected to the sensor unit 120 using at least one of wire communication and wireless communication. Accordingly, the variable portion 140 can receive the direction information of the gas sensed by the sensor portion 120 and expand or collapse the spoiler 130. The length of the variable portion 140 is adjusted. For example, each of the four variable mechanisms may be independently adjusted in length, or may be adjusted in length at the same time. Accordingly, the variable portion 140 can adjust the inclination of the spoiler 130. For example, when the wind is blowing, the length of the variable portion 140 is increased, so that one side of the spoiler 130 can be separated from the hull 110. In this case, the spoiler 130 which is in contact with the hull 110 and tilted horizontally tilts to increase the contact area of the spoiler 130 in contact with the base body, thereby increasing the thrust. For example, when the backward wind blows, the variable portion 140 may be made horizontal by contacting one side of the spoiler 130, which is spaced apart from the hull 110, with the hull 110 by reducing the length thereof. In this case, the contact area of the spoiler 130 in contact with the gas can be reduced, so that the resistance received from the gas can be reduced. The variable portion 140 may increase or decrease the contact area where the spoiler 130 contacts the gas by adjusting the inclination of the spoiler 130 by increasing or decreasing the length according to the direction in which the gas is blown. The variable section 140 may include a first variable mechanism 141, a second variable mechanism 142, a third variable mechanism 143, and a fourth variable mechanism 144.

The inclination of the spoiler 130 can be adjusted by adjusting the length of the variable portion 140.

3, when a positive wind (W1) is blown toward the hull 110, the ship 100 having the variable spoiler according to the present invention includes the first variable mechanism 141 and the second variable Thereby increasing the length of the mechanism 142. In this case, the lengths of the third variable mechanism 143 and the fourth variable mechanism 144 are not increased. Accordingly, the height of the first quadrant and the second quadrant of the spoiler 130 becomes a tilted shape higher than the height of the third and fourth quadrants. The spoiler 130 enters the space formed between the spoiler 130 and the hull 110, so that the contact area of the spoiler 130 in contact with the positive wind is increased. Accordingly, the ship 100 having the variable spoiler according to the present invention can generate the thrust F1 on the spoiler 130 by the wind of the normal wind to reduce the required horsepower required for the propulsion.

4, when a forward wind (W2) blows toward the hull 110, the ship 100 having the variable spoiler according to the present invention includes the first variable mechanism 141, the second variable The spoiler 130 is brought into contact with the hull 110 by reducing the length of the mechanism 142, the third variable mechanism 143 and the fourth variable mechanism 144. In this case, the lengths of the variable mechanisms may be the same. Accordingly, the contact area of the spoiler 130 with respect to the gas blowing to the hull 110 is reduced, thereby minimizing an increase in the resistance due to the hull 110 being mounted on the spoiler 130.

5, when the right wind (W3A) blows toward the hull 110, the ship 100 having the variable spoiler according to the present invention increases the length of the first variable mechanism 141 . In this case, the lengths of the second variable mechanism 142, the third variable mechanism 143, and the fourth variable mechanism 144 are not longer than the lengths of the first variable mechanism 141. The length of the fourth variable mechanism 144 may be shorter than that of the variable mechanisms. Accordingly, the height of the spoiler 130 is the highest in the first quadrant. The spoiler 130 enters the space formed between the spoiler 130 and the hull 110 so that the contact area of the spoiler 130 in contact with the right wind wind is increased. Therefore, the ship 100 having the variable spoiler according to the present invention can generate thrust to the spoiler 130 by the wind wind of the right wind wind to reduce the required horsepower required for the propulsion.

Referring to FIG. 6, when the left windwave W3B blows toward the hull 110, the ship 100 having the variable spoiler according to the present invention increases the length of the second variable mechanism 142 . In this case, the lengths of the first variable mechanism 141, the third variable mechanism 143, and the fourth variable mechanism 144 are not longer than the length of the second variable mechanism 142. The length of the third variable mechanism 143 may be the shortest of the variable mechanisms. Accordingly, the height of the spoiler 130 in the second quadrant is highest. The spoiler 130 enters the space formed between the spoiler 130 and the hull 110 so that the contact area of the spoiler 130 in contact with the left windwave increases. Therefore, the ship 100 having the variable spoiler according to the present invention can generate thrust to the spoiler 130 by the left wind wind to reduce the required horsepower required for the propulsion.

7, when the right side wind W4A and the left side wind W4B are blown toward the hull 110, the ship 100 having the variable spoiler according to the present invention has the first variable mechanism 141 The spoiler 130 is brought into contact with the hull 110 by reducing the length of the second variable mechanism 142, the third variable mechanism 143 and the fourth variable mechanism 144. In this case, the lengths of the variable mechanisms are the shortest length and may be the same length. Accordingly, the spoiler 130 can minimize a further increase in resistance caused by the contact with the gas flowing into the hull 110 due to the reduced contact area with the hull 110.

8, when a forward wind W2 is blown toward the hull 110 and the ship 100 is braked, the ship 100 having the variable spoiler according to the present invention is configured such that the third variable mechanism (143) and the fourth variable mechanism (144). In this case, the lengths of the first variable mechanism 141 and the second variable mechanism 142 may not be increased. Accordingly, the height of the third and fourth quadrants of the spoiler 130 becomes higher than the height of the first quadrant and the second quadrant. The spoiler 130 enters the space formed between the spoiler 130 and the hull 110 so that the contact area of the spoiler 130 in contact with the forward wind increases. Accordingly, the ship 100 having the variable spoiler according to the present invention can generate the reverse thrust opposite to the thrust force to the spoiler 130 by the wind force of the normal wind to reduce the operating speed and shorten the braking distance. Although not shown, the ship 100 having a variable spoiler according to the present invention can braking force by adjusting the inclination of the spoiler 130 to other reverse winds other than the forward wind W2. Particularly, the ship 100 having a variable spoiler according to the present invention adjusts the spoiler 130 in an urgent situation where there is a risk of collision with another ship, thereby reinforcing the braking force, thereby shortening the braking distance, have. The variable spoiler including the spoiler 130 and the variable portion 140 may be installed on a ship as in the present invention but is not limited thereto and any equipment that generates resistance to fluid may be installed in other equipment such as a heavy truck .
