られている。By the way, if the opening of such a thruster tunnel remains open during navigation, the wave-making resistance increases due to the vortex flow generated around the opening, and the fuel efficiency of the ship is likely to deteriorate. Also, when the opening exposed on the water surface is submerged again due to pitching during navigation, the residual air in the thruster tunnel becomes bubbles and flows into the water. Will interfere with the reception of. Therefore, it is desirable to close the opening of the thruster tunnel during navigation, and for this reason, for example, JP-A-2-22739 proposed by the present applicant.
As in 7, a bow thruster gate device is known in which a gate is slid up and down via a driving means such as a hydraulic cylinder.

Furthermore, since the thruster gate 1 rises and falls in a narrow storage space while standing almost vertically, the center of gravity position 20 of the thruster gate 1 may be near the line of force of the link 8 and may not be stable. There was a risk that the thruster gate 1 would fluctuate, causing sticking due to collision with the hull.

As shown in FIG. 7, the thruster gate 1 starts to move along a guide rail 5 that guides the guide pins 4 and 9 toward a storage position diagonally above. Immediately after the start of this movement, the guide stopper 16 slides on the outside of the guide rail 5 and is guided. The thruster gate 1 is restricted from swinging in the inner direction of the hull by the back stopper 13 and in the outer direction of the hull by the guide stopper 16, and can be stably pulled up to the storage position without swaying left and right around the guide pin 4. When the direction of the bow is changed in a harbor or the like, the thruster tunnel 2 is opened in this way, and a propulsion device (not shown) mounted in the thruster tunnel 2 is driven.

タゲート１の上部の船体外側方向の回動を許容する。On the other hand, when the thruster gate 1 is moved from the retracted position to the closed position in order to close the opening of the thruster tunnel 2, the contracted hydraulic cylinder 12 is extended. As a result, the thruster gate 1 becomes the back stopper 1
While being prevented from swinging by 3 and the guide stopper 16, the guide stopper 16 is separated from the guide rail 5 as shown in FIG. 6, and the guide pin 4 contacts the pedestal 6 as shown in FIG. When reaching the opening position, the upper part of the thruster gate 1 is allowed to rotate in the outer direction of the hull.

る。When the hydraulic cylinder 12 is further extended from this state, the guide pin 9 which continues to descend is linked by the link 8
The upper portion of the thruster gate 1 is pushed out to the outside of the hull through the guide, and the upper portion of the thruster gate 1 rotates in the outer direction of the hull with the guide pin 4 as a fulcrum to reach the closed position shown in FIG.

生じることもなく、航行中の造波抵抗も極めて小さい。In the closed position, the thruster gate 1 presses the upper support 14 from the inside to the hull skin 3 by the rotational force exerted on the thruster gate 1 by the hydraulic cylinder 12 via the guide pin 9 and the link 8. In addition, since the lower part is crimped from the outside to the support 15 formed on the hull outer plate 3, sufficient supporting force can be obtained against external pressure such as waves.
Furthermore, there is no step between the thruster gate 1 and the hull skin 3, and the wave-making resistance during navigation is extremely small.

Depending on the position, it may be difficult to mount the hydraulic cylinder 12 inside the hull. In such a case, as shown in FIG. 8, the piston rod 1 of the hydraulic cylinder 12 is
By disposing 2B on the hull side and the cylinder 12A on the thruster gate 1 side and connecting the guide pin 9 in the middle of the cylinder 12A, while ensuring the stroke of the hydraulic cylinder 12 required for lifting the thruster gate 1, The overall height of the device can be suppressed.
