The specific structure and functions of the invention are as follows:

the fin box 4 is a part of the hull 1, the size of the fin box 4 is determined by the fins of the stabilizer 3, and after the stabilizer 3 is recovered to the fin box 4, a part of space inside the fin box 4 can be used for placing a capping device.

The area of the inner wall of the fin box 4, which is contacted with the sealing cover device, is covered with a layer of polymer lubricating material, so that the whole sealing cover device can be effectively ensured to smoothly slide in the fin box 4, and meanwhile, the inner cavity is effectively ensured to be watertight by the polymer lubricating material.

The cover 6 is a combination of a thin steel plate and a polymer material, and is mounted in the fin box 4. The shape of the sealing cover 6 is determined according to the line shape of the ship body at the opening of the fin box 4, so that the sealing cover 6 can be ensured to be matched with the line shape of the ship body after extending out.

The thin steel plate is provided with a high polymer lubricating material on a curved surface contacted with the fin box 6, and the width of the high polymer lubricating material is smaller than that of the end part of the sealing cover 6;

the steel sheet is provided with grooves on the curved surface contacting with the fin box 6, and the polymer lubricating material can be installed in the grooves, so that the polymer material is firmly installed on the steel sheet.

The thin steel plate is not contacted with the fin box 4, and a foldable densely covered 7 is arranged on the curved surface.

The height direction of the foldable dense 7 is provided with a supporting rod, and the supporting rod can ensure that the dense is folded along the length direction of the fin box 4 without collapsing into a group.

The foldable dense 7 is a watertight pressure-bearing member, and can bear the pressure of the seawater pump 13 after being fully extended.

The length of the foldable densely distributed materials 7 is slightly shorter than the sum of the lengths of the inner cavity and the outer cavity of the fin box 4, so that the densely distributed materials can be effectively stretched when the capping device is pushed out.

The two ends of the foldable dense 7 in the height direction are provided with high polymer materials which can slide in the fin box 4.

One side of the foldable dense 7 is connected with the thin steel plate in a watertight manner, and the other side is connected with the front end of the inner cavity of the fin box 4 in a watertight manner.

The sealing cover 6 and the foldable dense cloth 7 are contacted with the inner wall of the fin box 4, and the fin box 4 is divided into an inner cavity and an outer cavity.

The sealing cover 6 is mounted with the inner wall of the fin box 4 in interference fit, so that the inner cavity and the outer cavity of the fin box 4 are relatively watertight.

A circle of baffle ring 15 is arranged at the outer end of the fin box 4, and a travel switch is arranged on the baffle ring 15, and if the baffle ring 15 is touched by a sealing cover device, a signal can be transmitted to the control box 10.

The position of the baffle ring 15 can ensure that the outer edge of the capping device is exactly in line fit with the outer plate of the hull 1 after touching the capping device.

One side of the suction port of the seawater pump 13 is connected with an on-board seawater main pipe to provide seawater, and the other side is connected with the inner cavity of the fin box 4 through a water inlet control valve 12.

The water inlet control valve 12 is a remote control stop valve and is arranged on a pipeline of the seawater fin inlet tank 4, and the opening and closing of the water inlet control valve is controlled by the control tank 10.

The water outlet control valve 9 is a remote control stop valve and is arranged on a pipeline of the seawater fin outlet tank 4, and the opening and closing of the water outlet control valve is controlled by the control tank 10.

The water outlet pipeline 8 can discharge the water in the inner cavity of the fin box 4 out of the board through the water outlet control valve 9.

The control box 10 receives the running state signal of the stabilizer 3 and the travel switch signal of the baffle ring 15, and simultaneously controls the running of the seawater pump 13, the water inlet control valve 12 and the water outlet control valve 9.

In the actual working process:

the power source of the capping device can adopt pressurized seawater, compressed air, a hydraulic device and the like, and the embodiment takes the pressurized seawater as an example to describe the specific implementation.

When the stabilizer 3 does not work, the stabilizer 3 is in the fin box 4, the capping device is retracted to the innermost side of the fin box 4, the foldable packing 7 at one end of the capping device is retracted into the inner cavity, and the stabilizer 3 is outside the capping device. The fin box 4 is filled with the stabilizer 3 for most of its space.

And (1) the stabilizer 3 extends out:

when the stabilizer 3 works, the fin box 4 stretches out, the fin box 4 is empty, at the moment, after the control box 10 receives the stretching state of the stabilizer 3, the water inlet control valve 12 is controlled to be opened, the water outlet control valve 9 is closed, the seawater pump 13 is put into operation, the seawater pump 13 pumps seawater into the inner cavity of the fin box 4 through the seawater pipe 14, the pressure of the inner cavity of the fin box 4 is gradually increased along with continuous pumping of seawater, the sealing cover device receives continuously increased pressure and gradually slides towards the outer cavity under the pressure, and the foldable dense 7 at one end of the sealing cover device gradually slides and expands along the inner part of the fin box 4 under the guidance of the sealing cover device.

When the capping device gradually slides outwards and touches the baffle ring 15 at the outer end surface of the fin box 4, the baffle ring 15 feeds back a touch signal to the control box 10, and after the control box 10 acquires the touch signal, the water inlet control valve 12 is closed, and the seawater pump 13 is closed. At this point the collapsible glue 7 is pulled tight by the capping device and the cavity is kept at a constant pressure.

When the seawater in the inner cavity penetrates the seawater outwards through the outer cavity, the pressure in the inner cavity is smaller than the pressure outside, the sealing cover device slides into the cavity, the touch signal on the baffle ring 15 disappears, the control box 10 starts the seawater pump 13 to supply water to the inner cavity until the sealing cover device returns to the set position from new, the touch signal of the baffle ring 15 is transmitted to the control box 10, and the control box 10 closes the seawater pump 13.

The line shape of the sealing cover device is matched with the line shape of the ship body, so that the flow field of the ship body is not greatly influenced.

(II) the stabilizer 3 is retracted:

the stabilizer 3 is retracted into the fin inlet box 4 by the recovery device, a retraction signal of the stabilizer 3 is transmitted to the control box 10, and the control box 10 opens the water outlet control valve 9.

During the retracting process of the stabilizer 3, the fin edges push the sealing cover 4 into the inner cavity, the foldable dense 7 is extruded to the front wall of the fin box 4 by the sealing cover 4 device, and the stabilizer is slowly folded. At the same time, the capping device discharges the inner cavity seawater to the outside through the outlet control valve 9 until the retraction process is completed.

The above description is intended to illustrate the invention and not to limit it, the scope of which is defined by the claims, and any modifications can be made within the scope of the invention.
