Abstract

PURPOSE:To prevent a lug from being formed outside of a hull by constituting said cover device so that the cover proper can be lifted or lowered and stored in a trunk body to open a duct. CONSTITUTION:In a cover device, a cover proper 7 is opened or closed by an operation of a drive mechanism 8. Under a normal condition, the cover proper 7 closes a duct opening 101 nearly at the same surface as the hull shape without forming any lug outside of the hull. When the drive mechanism 8 is operated at this condition, the cover proper 7 is lifted while being guided by a rail body 9 and stored in a trunk body 6 to open a duct. At this time, the cover proper 7 is only drawn into the trunk body 6 above, thus the duct can be opened with no resistance.

Medium-sized ships are equipped with ship lights and side thrusters at the stern. This lead thruster has a duct that penetrates the ship's width direction at the bow and stern, and a propulsion device is installed inside this duct.
It is designed to change direction. The openings on both sides of the hull of the duct where the side thrusters are located are provided with covers to eliminate resistance when the ship is sailing at high speed. It uses a lid that slides up and down on the outside. However, in the former method, there is a large resistance when opening, and it may be damaged by wave impact, and in the latter case, it is necessary to provide a guiding hole on the outer panel, which increases water resistance. It has the disadvantage of being

Correspondingly, it is designed in an inclined manner. When the duct opening (101) is closed, its sloping outer surface is exposed to the hull shell and the road surface, and the vertical outer surface of the upper part of the duct is exposed to the inner surface of the periphery of the duct opening (11+).
) The rank body (6) can still touch the inner wall of the lower part. Further, the lower peripheral edge of the cover body (7) is formed in an arc shape, and the bottom (71) of the arc-shaped peripheral edge is laid out horizontally. On the other hand, the lower part of the duct opening (101) (opening in the hull shell) to be closed by the cover body (7) has an arc shape, and the cover body (7) A member Ov is attached to the receiver in which a groove (111) is formed for fitting the arcuate peripheral edge of the member Ov. However, the part of this support corresponding to the arcuate bottom of the 0th member has a support part that supports the ear part of the cover main body (
112) is formed! There is no groove e formed in this part, and the front rK2 bottom (7) of the cover body (7) is located in this part.
1) I am working hard to make sure that I can meet you. Note that an ear portion (72) is formed on the arcuate periphery of the cover body (7).

ることもできることは言うまでもない。The driving mechanism (8) is provided in the trunk body (6) and the base portion 1, and in this embodiment, it is constructed by a cylinder device. That is, the cylinder assembly 1 is fixed to the upper part of the trunk body (6), and the 1,000 liters (81) are attached to the cover body (6).
7) is fixed on the back. In addition, this drive mechanism (3
), it goes without saying that a drive morph (for example, a hydraulic morph) or the like can be used.

できる。In the above cover device, the cover main body (7) is opened and closed by operating the drive mechanism (8). Under normal conditions, the cutter main body (7) has no protrusions on the outside of the hull, and the duct opening (lOl) is connected to the hull shape and the road surface.
It's blocked. When the drive mechanism (8) is activated from this state, it rises while being guided by the rail body (9) and is housed in the trunk body (6), opening the duct. At this time, the cover body (7) is simply pulled into the trunk body (6) above, so that the duct can be opened without any resistance.

) in the figure (A), CB), (
Since the upper front and rear surfaces and the lower part of the part C) are restrained and held, sufficient strength can be obtained even against external pressure caused by waves. In addition, the bottom (7) of the cover body (7)
1) is structured in the shape of water 51', and the receiver that this part of L should still contact is formed with a groove in the part of member 01), so that through this part the receiver is connected to the groove in the center of member Q. (111) can easily flow out of the vessel, causing the foreign matter in the groove (
Remaining foreign matter in the tti) is appropriately prevented.
