The specific structure and function 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 fin stabilizer 3, and after the fin stabilizer 3 is recovered to the fin box 4, there is a space inside the fin box 4 for placing a cover.

The region of the inner wall of fin case 4 and closing cap device contact covers the one deck polymer lubricating material, can effectively guarantee that whole closing cap device smoothly slides in fin case 4, and simultaneously, polymer lubricating material can effectively ensure the inner chamber watertight.

The cover 6 is a combination of a thin steel plate and a polymer material, and is installed in the fin box 4. The shape of the sealing cover 6 is determined according to the line type 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 type of the ship body after extending out.

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

the thin steel plate is provided with a groove on a curved surface which is contacted with the fin box 6, and the high polymer lubricating material can be arranged in the groove, so that the high polymer material is ensured to be firmly arranged on the thin steel plate.

Foldable dense cloth 7 is arranged on a curved surface where the thin steel plate is not in contact with the fin box 4.

The supporting rods are arranged in the height direction of the foldable dense cloth 7, and the supporting rods can ensure that the dense cloth can be folded along the length direction of the fin box 4 without collapsing and forming a lump.

The foldable dense cloth 7 is a watertight pressure bearing member and can bear the pressure of the seawater pump 13 after being completely extended out.

The length of the foldable dense cloth 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 dense cloth can be effectively tightened when the sealing cover device is pushed out.

The two ends of the foldable dense cloth 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 cloth 7 is connected with the thin steel plate in a watertight way, and the other side is connected with the front end of the inner cavity of the fin box 4 in a watertight way.

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

The sealing cover 6 and the inner wall of the fin box 4 are installed in an interference fit mode, and the inner cavity and the outer cavity of the fin box 4 are relatively watertight.

A ring of stop rings 15 are arranged at the outer end of the fin box 4, travel switches are arranged on the stop rings 15, and if the stop rings 15 are touched by the cover sealing device, signals can be transmitted to the control box 10.

The position of the baffle ring 15 can ensure that the outer edge of the sealing device is just matched with the line type of the outer plate of the ship body 1 after the sealing device is touched.

One side of a suction port of a seawater pump 13 is connected with an onboard seawater main pipe to provide seawater, and the other side of the suction port is connected with an 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, is installed on the pipeline of the seawater fin inlet box 4, and is controlled by the control box 10 to open and close.

The water outlet control valve 9 is a remote control stop valve, is arranged on a pipeline of the seawater outlet fin box 4, and is controlled by a control box 10 to open and close.

The water outlet line 8 can drain the water in the chamber of the fin box 4 out of the board through the water outlet control valve 9.

The control box 10 receives the operation state signal of the fin stabilizer 3 and the travel switch signal of the baffle ring 15, and controls the operation 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 seawater with pressure, compressed air, a hydraulic device and the like, and the embodiment takes the seawater with pressure as an example to explain a specific implementation mode.

When the fin stabilizer 3 does not work, the fin stabilizer 3 is in the fin box 4, the cover device is recovered to the innermost side of the fin box 4, the foldable dense cloth 7 at one end of the cover device is recovered to the inner cavity, and the fin stabilizer 3 is outside the cover device. The fin box 4 is mostly filled with the stabilizer fins 3.

The fin stabilizer 3 extends out:

when the fin stabilizer 3 works, the fin box 4 extends out, at the moment, the fin box 4 becomes empty, at the moment, after the control box 10 receives the extending state of the fin stabilizer 3, the water inlet control valve 12 is controlled to be opened, the water outlet control valve 9 is closed, the sea water pump 13 is put into work, the sea water pump 13 pumps the sea water into the inner cavity of the fin box 4 through the sea water pipe 14, the pressure of the inner cavity of the fin box 4 is gradually increased along with the continuous pumping of the sea water, the sealing cover device is subjected to continuously increased pressure and slides towards the outer cavity gradually under the pressure, and the foldable dense cloth 7 at one end of the sealing cover device is guided by the sealing cover device to slide and expand along the inner part of the fin box 4 gradually.

When the cover sealing device gradually slides outwards and touches the stop ring 15 on the outer end face of the fin box 4, the stop 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 cloth 7 is tensioned by the closure device and the inner cavity is maintained at a constant pressure.

When seawater permeates into the inner cavity through the outer cavity, the pressure of the inner cavity is smaller than the outboard pressure, the sealing cover device slides towards the inner cavity, the touch signal on the retaining 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 the beginning, the touch signal of the retaining ring 15 is transmitted to the control box 10, and the seawater pump 13 is closed by the control box 10.

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

(II) retraction of the stabilizer fin 3:

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

During the retraction of the fin stabilizer 3, the fin edge pushes the cover 4 into the inner cavity, and the foldable dense cloth 7 is squeezed by the cover 4 device to the front wall of the fin box 4 and is slowly folded. Meanwhile, the cover device discharges seawater in the inner cavity to the outboard through the water outlet control valve 9 until the recovery process is completed.

The above description is intended to be illustrative and not restrictive, and the scope of the invention is defined by the appended claims, which may be modified in any manner within the scope of the invention.
