Abstract

The present invention relates to a ship comprising: a hull which has a coupling space in the bottom of the bow; a bow bulb which is installed in the coupling space; and a sliding part which couples the bow bulb to the hull through sliding. According to the present invention, the bow bulb of the ship having various sizes and shapes is manufactured through a sliding and detaching structure to replace the bow bulb with an optimized bow bulb whenever a target speed is changed to improve the energy efficiency of the ship, thereby facilitating a replacement work when the bow of the ship is remodeled and enabling replacement even on the sea without entering a dock. Therefore, the present invention contributes to reducing time and remodeling costs required for replacing the bow bulb.

Description

Ship {Ship}

The present invention relates to a ship.

Generally, when a ship is operated, a regular wave occurs at aft and stern, which is called a wave resistance, and this wave resistance causes loss of operating energy of the ship. In order to minimize the wave resistance and increase the speed of the ship, a bow bulb is installed on the bow of most ships.

The player's bulb is formed with spheres of appropriate size and shape according to the ship's linearity or speed. If such a bulb is installed on the inclined portion of the bow, the bow generated by the wave resistance generates wave and wave interference generated by the bow bulb, and the bow wave is canceled by such wave interference. In other words, waves generated at the slope of the bow are wavecancelled due to waves generated by the bow bulb.

Since the size or shape of the bow bulb varies depending on the shape or speed of the ship, it is difficult to determine a uniform size or shape, and the size or shape of the bow bulb is slightly different depending on the draft of the ship. Therefore, the bow bulb is designed and manufactured to be optimized for the ship's operating conditions (line speed, draft, working load, etc.) and installed on the ship.

However, since the linearity of the ship with the bow bulb is not changed, it is inevitable to optimize the designing operation condition for one, and there is a problem that the optimal shape for the designing operation condition can not be achieved for optimization of various operation conditions. There is a limitation in reducing the operating energy loss of the ship due to the increase of the power consumption of the ship.

In order to solve this problem, when the target line speed is changed, the loss of the operation energy of the ship is reduced through the modification of the athlete, but when the ship is modified, the ship is reintroduced into the dock and the bulb correction is carried out, .

The second guide protrusion 234 may be a T-shaped protrusion such that the second guide protrusion 234 can be inserted into the second guide groove 232 formed on the rear surface of the second engagement space 212.

The second bow bulb 220 with the second guide protrusion 234 can have various sizes and shapes such that it can be replaced with a bow bulb optimized each time the target bowling speed is changed to increase the operating energy efficiency of the vessel 200. [ .

Unlike the first fore-and-aft bulb 120 of the first embodiment having the detachment structure of the front-and-rear sliding type, the second fore-and-aft bulb 220 has the detachment structure of the up-and-down sliding type. It may not be easy to assemble or disassemble using only the transfer device. In order to solve this problem, as shown in FIG. 3, the second player bulb 220 may further include a tank 222 therein.

Specifically, the second bow bulb 220 is lowered below the bottom of the second hull 210 and then slides in the upper-right room and is assembled in the second engagement space 212 of the second hull 210, It must slide from the second hull 210 to a position directly below the bottom of the second hull 210. However, if the second bow bulb 220 does not sink to the bottom of the second hull 210 due to the buoyant force of the second bow bulb 220, A separate device for lowering the second bow bulb 220 to the bottom of the second hull 210 is required in addition to the conveying device such as a conveyor belt and the like. .

In this embodiment, the tank 222 is provided inside the second bow bulb 220, and the second bow bulb 220 is connected to the second hull 210 in such a manner that the tank 222 is filled with water, To be raised or lowered below the bottom of the vessel.

The second bow bulb 220 may further include a lug box portion 140.

As shown in FIG. 6, the lug box portion 140 may be provided in one pair or more on both sides of the second player bulb 220, and the configuration and the role may be the same as those described in the first embodiment The detailed description will be omitted here.

The second sliding portion 230 is provided on the rear side of the second articulation bulb 220 so that the second articulation bulb 220 can be attached to and detached from the second engagement space 212 in an up- A guide protrusion 234 and a second guide groove 232 formed on a rear surface of the second engagement space 212. [

The second sliding portion 230 is formed in such a manner that the second guide protrusion 234 is inserted into the second guide groove 232 and slides upward or downward so that the second swinging bulb 220 is assembled to the second hull 210 Or decomposed.

When the second bow bulb 220 is assembled to the second hull 210 through the second sliding portion 230, the upper surface of the second bow bulb 220 and the second coupling space 212 of the second hull 210 And the rear surface of the second bow bulb 220 and the rear surface of the second engagement space 212 of the second hull 210 are in contact with each other so that seawater is prevented from penetrating into the gap formed in the contacting portion A watertight member (not shown) is mounted along the upper and rear rims of the second bow bulb 220 or a watertight member (not shown) is attached along the upper and rear rims of the second engagement space of the second hull 210 (Not shown).

When the second articulation bulb 220 is assembled to the second hull 210 through the second sliding portion 230, the rear surface of the second articulation bulb 220 in which the second sliding portion 230 exists, The second bow bulb 220 is securely engaged with the second hull 210 by the second guide groove 232 and the second guide projection 234 on the rear surface of the second engagement space 212 of the two- The coupling force is inevitably weak on the upper surface of the second bow bulb 220 where the second sliding portion 230 does not exist and the upper surface of the second coupling space 212 of the second hull 210, As described above, the coupling means (not shown) may be provided on the upper surface of the second engagement space 212 to couple or fix the second engagement space 212 to the second articulation bulb 220, To the second hull (210).

The fixing portion 150 may be coupled and fixed to the second hull 210 and the second bow bulb 220 by a bolting method using bolts 152 as shown in FIG. The fixing portion 150 may be formed along a portion where the upper surface of the second bow bulb 220 and the upper surface of the second engagement space 212 of the second hull 210 are in contact with each other.

Each of the plurality of fixing portions 150 can be penetrated into the interior of the water tank when the water tank is directly exposed to the sea water, so that a watertight member (not shown) can be further provided.

As described above, the present embodiment is characterized in that, in order to increase the efficiency of operation of the ship 100, 200, the bow of the ship having various sizes and shapes, such that it can be replaced with the bow bulbs 120, 220 optimized each time the target line speed is changed, By constructing the bulbs 120 and 220 in a sliding detachable structure, not only can the replacement operation be facilitated when the ship's athlete is rebuilt, but also the sea can be replaced without re-entering the dock. Can be reduced.
