Description

Technical Field

[0001] The invention relates to the technical field of underwater submersible power anti-sinking equipment, in particular to a folding wing capable of resisting heeling during emergency buoyancy and a use method thereof. Background Art

[0002] As the diving depth increases, the pressure resistance problem of submersibles becomes increasingly prominent. Compared with a single large pressure chamber, the cross-section multi-pressure chamber arrangement can effectively improve the pressure resistance, reduce the construction difficulty, and save costs. Under high pressure in the deep sea, damage to the pressure chamber will produce extremely high inflow velocity and large water intake, resulting in a decrease in the metacentric height of the hull and rapid sinking.

[0003] For emergency anti-sinking in the deep sea, a gravity-type dumping mechanism is usually used. However, this mechanism needs to be within a specific heel angle (such as 45° or less) to successfully dump loads. If water enters the pressure compartment on one side, it will cause severe heeling, causing the dumping mechanism to be unable to dump loads, threatening the safety of the hull. For deep-sea submersibles, the dumping mechanism is related to the safety of the hull. Equipping two groups on the left and right can improve the anti-heeling ability and safety margin. When the amount of water entering one side is not too much and the leak is ideal, the unilateral dumping can effectively reduce the heel and achieve emergency buoyancy.

[0004] During the process of floating after dumping the load, water in the pressure cabin weakened the effect of dumping the load, reduced the metacentric height and the floating speed, which was not conducive to rapid escape. During the floating, the horizontal wing of the submersible had a large resistance, causing serious attitude instability and even causing the hull to capsize. In addition, the emergency floating speed of the submersible was high, and it would suffer a large impact load when it fell out of the water, which seriously threatened the structural safety of the horizontal wing.

[0005] Although the horizontal wings can be folded by a folding mechanism, it requires a pressure-resistant hydraulic cylinder or electric motor, which is complex, costly, and low in durability, making it difficult to cope with serious faults such as power outages and equipment damage. If the folding mechanism is only used for anti-roll and equipment protection during emergency buoyancy, the frequency of use is too low, and the cost-effectiveness is particularly unsatisfactory.

[0006] There is no low-cost, high-reliability solution to the above problems, and new designs need to be developed. Summary of the invention

[0007] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a folding wing that can resist heeling during emergency buoyancy and a method of use, so that it does not require power, does not require pressure resistance, has strong anti-interference ability, high reliability, and low system burden, and can be used as a conventional safety reserve device to meet usage requirements.

[0008] The technical solution adopted by the present invention is as follows:

[0009] A folding wing capable of resisting heeling in emergency buoyancy comprises a horizontal wing assembly, a two-degree-of-freedom rotating member, a supporting assembly, a sliding assembly and a hull assembly, wherein the hull assembly comprises a light outer shell, on which a recovery groove of the horizontal wing assembly is symmetrically arranged, a symmetrical pressure-resistant cabin is arranged inside the light outer shell, a left group of dumping loads and a right group of dumping loads are arranged below the pressure-resistant cabin respectively, a two-degree-of-freedom rotating member, a supporting assembly and a sliding assembly are arranged in the middle position above the pressure-resistant cabin, and a horizontal wing assembly is arranged in the recovery groove, and a single horizontal wing assembly comprises a wing plate and a rotating shaft;

[0010] The mounting structure of a single wing plate is as follows: it includes a support shaft base fixed inside the light shell, a support shaft is vertically fixed in the middle of the support shaft base, an external gear bearing is arranged below the support shaft, one end of the rotating shaft is connected to the wing plate, and the other end is fixedly connected to the outer ring of the rotating bearing, the inner ring of the rotating bearing is fixedly connected to the lifting slider, the lifting slider is sleeved on the support shaft, a limiting cylinder and a rotating bearing are arranged outside the lifting slider, the bottom of the limiting cylinder is fixedly connected to the outer ring of the rotating bearing, a spring is installed on the support shaft located below the outer ring of the rotating bearing and between the outer ring of the external gear bearing; a limiting plate assembly is installed on the top surface of the limiting cylinder, a slip ring is located above the limiting plate assembly, a counterweight block is arranged above the slip ring, a positioning bead is installed in the middle of the counterweight block, a horizontal slide rail is crossed inside the slip ring, both ends of the horizontal slide rail are fixedly connected to the hull through the slide rail base, and a groove for the positioning bead to engage is provided in the center of the upper plane of the horizontal slide rail.

[0011] Its further technical solution is:

[0012] The wing plate has negative buoyancy under water, and the center of gravity of the wing plate is in front of the rotating shaft.

[0013] The wing plate is in a horizontal state, and the end surface of the wing plate is parallel to the middle longitudinal section.

[0014] The rotating bearing is unidirectional and can only rotate clockwise when viewed from the hull.

[0015] The lifting slide block is a cylindrical ball guide sleeve.

[0016] The lower part of the limiting cylinder adopts a cylindrical shell, the upper part of the limiting cylinder adopts a disc structure, and the upper plane of the limiting cylinder is provided with a cross groove.

[0017] The inner ring of the outer gear bearing is fixed on the supporting shaft and cannot move up and down, and the outer ring is provided with a gear and can rotate around the axis.

[0018] The axes of the rotary bearing, the external gear bearing and the supporting shaft are the same.

[0019] The limit plate assembly is divided into a high limit plate and two left and right low limit plates, and both the high limit plate and the low limit plate are rigid rectangular thin plates with the same thickness.

[0020] A method for using folding wings capable of resisting heeling in emergency buoyancy comprises the following steps:

[0021] S1: Automatic response when the boat tilts greatly and loses depth;

[0022] When the submersible is damaged underwater and water is entering, the vehicle is tilted and falls in depth. If the tilt angle of the hull exceeds the allowable angle of the dumping mechanism, the device will be automatically triggered to respond to the anti-tilt.

[0023] S2: Gravity drive release limit;

[0024] When the hull is tilted greatly, the gravity drives the sliding assembly to overcome the restriction of the positioning beads and slide to the end of the sinking side, thereby releasing the rotation restriction on the raised side wing plate and reducing the rotation restriction force on the wing plate on the sinking side;

[0025] S3: When falling deep, the wing plate on one side is folded to reduce the heel;

[0026] The lifted side wing plate is driven by gravity to rotate and retract into the hull, and energy is stored in the spring system at the same time. When the lifted side wing plate is completely rotated into the hull, the spring pushes the limit cylinder to move upward and embed into both sides of the slide rail to completely lock the rotation;

[0027] During the process of falling to depth, the side wing is lifted and recovered into the hull, and the side wing is sunk to generate an anti-heeling moment, reducing the hull's heel and facilitating the dumping of loads;

[0028] S4: Automatically recover the wing on the other side when floating;

[0029] During the buoyancy process after dumping the load, the hydrodynamic thrust from top to bottom moves the sinking side wing downward, releasing the rotation restriction. Driven by the energy storage spring, the wing on the sinking side rotates and is recovered into the hull. The spring pushes the limit cylinder upward and engages with the horizontal slide rail to lock the mechanism. During the buoyancy process, the wing is recovered into the hull, reducing the buoyancy resistance, increasing the buoyancy speed, and enhancing the stability of the buoyancy posture.

[0030] The beneficial effects of the present invention are as follows:

[0031] The present invention has a compact and reasonable structure and is easy to operate. Through the cooperation between the horizontal wing, the two-degree-of-freedom rotating part, the sliding limiter and the supporting assembly, the folding of the wing plate can be easily completed. The present invention is usually used as a horizontal wing. When the single compartment of the submersible is flooded, the heel is too large, and the load cannot be dumped, the device can recycle the single-side horizontal wing into the hull to form an anti-heel moment, reduce the heel, and facilitate the implementation of the dumping. When floating after dumping, the energy stored in the recovered wing plate is used to drive the other side wing plate to be recovered into the hull, reducing the heel unbalanced force and resistance during floating, and improving the floating speed and the stability of the posture. When leaving the water, the horizontal wing is recovered into the hull to protect the wing plate from the impact of wave loads. The device does not require power, does not require pressure resistance, has strong anti-interference ability, high reliability, and low system burden, and is convenient to be used as a conventional safety reserve device.

[0032] When the boat body rolls too much and cannot jettison the load, the device can automatically retract the single-side horizontal wing into the boat body without power, thereby forming an anti-rolling moment, reducing the roll angle, and facilitating the implementation of jettisoning the load.

[0033] When the present invention turns to floating after dumping, the energy stored in the recovery wing plate is used to drive the other side wing plate to be recovered into the boat body, thereby reducing the heel unbalanced force and resistance during floating, increasing the floating speed and enhancing the stability of the floating posture.

[0034] When the present invention is out of water, the horizontal wings are all recovered into the boat body, thereby reducing the impact load and facilitating the protection of the wing plate.

[0035] When the present invention has no large heel, it can be used as a horizontal wing and will not bring any burden to the boat body.

[0036] The present invention does not require power throughout the entire process, has strong anti-interference ability, high reliability, and improves safety reserves.

[0037] The present invention adopts a fully mechanical structural design without a pressure-resistant structure, is suitable for full sea depth, and has stable performance during long-term service.

[0038] The invention has small volume, light weight and low system burden, and is convenient for forming a conventional safety reserve device. BRIEF DESCRIPTION OF THE DRAWINGS

A counterweight block 43 is arranged above the slip ring 42, and a positioning bead 44 is installed in the middle of the counterweight block 43. A horizontal slide rail 33 runs across the inside of the slip ring 42, and both ends of the horizontal slide rail 33 are fixed to the hull through a slide rail base 34.

[0059] The wing plate 11 has negative buoyancy underwater, and the center of gravity of the wing plate 11 is in front of the rotating shaft 12 .

[0060] The wing plate 11 is in a horizontal state, and the end surface of the wing plate 11 is parallel to the middle longitudinal section.

[0061] The rotating bearing 21 is unidirectional and can only rotate clockwise when viewed from the hull.

[0062] The lifting slide block 22 is a cylindrical ball guide sleeve.

[0063] The lower part of the limiting cylinder 23 adopts a cylindrical shell, the upper part of the limiting cylinder 23 adopts a disc structure, and the upper plane of the limiting cylinder 23 has a cross groove.

[0064] The inner ring of the outer gear bearing 25 is fixed on the support shaft 31 and cannot move up and down, and the outer ring has a gear and can rotate around the axis.

[0065] The axes of the rotary bearing 21, the external gear bearing 25 and the support shaft 31 are the same.

[0066] The limiting piece assembly 41 is divided into a high limiting piece 411 and two low limiting pieces 412 on the left and right. The high limiting piece 411 and the low limiting piece 412 are both rigid rectangular thin pieces with the same thickness.

[0067] The specific structure and function of the folding wing capable of resisting heeling during emergency floating described in the present invention are as follows:

[0068] It mainly includes a horizontal wing assembly, a two-degree-of-freedom rotating part, a supporting assembly, a sliding assembly and a hull assembly.

[0069] Among them, the horizontal wing assembly includes.

[0070] The wing plate 11 is negatively buoyant underwater, and its center of gravity is in front of the rotating shaft 12. The wing plate 11 is in a horizontal state, and its end surface is parallel to the mid-longitudinal section.

[0071] One end of the rotating shaft 12 is connected to the wing plate 11 , and the other end is fixedly connected to the outer ring of the rotating bearing 21 .

[0072] The two-degree-of-freedom rotating member includes a rotating bearing 21, a lifting slider 22, a limiting cylinder 23, a spring 24 and an external gear bearing 25;

[0073] The rotating bearing 21 is unidirectional and can only rotate clockwise when viewed from the hull. The inner ring of the rotating bearing 21 is fixedly connected to the lifting slide block 22 and moves up and down with it.

[0074] The lifting slider 22 is a cylindrical ball guide sleeve, which is sleeved on the support shaft 31 and can only slide up and down with low friction but cannot rotate horizontally.

[0075] The lower part of the limit cylinder 23 is a cylindrical shell, and the upper part is a disc structure. The bottom of the limit cylinder 23 is fixedly connected to the outer ring of the rotating bearing 21. The upper plane of the limit cylinder 23 has a cross groove. Among them, the groove perpendicular to the middle longitudinal section is the limit plate groove, and the width is slightly larger than the thickness of the limit plate. The other is the slide rail groove, the width is slightly larger than the width of the horizontal slide rail 33, and the depth is greater than the height of the low limit plate 412.

[0076] The spring 24 is sleeved on the support shaft 31 , and the upper part is fixedly connected to the lower part of the outer ring of the rotating bearing 21 , and the lower part is fixedly connected to the outer ring of the external gear bearing 25 .

[0077] The inner ring of the outer gear bearing 25 is fixed on the support shaft 31 and cannot move up and down, and the outer ring has a gear and can rotate around the axis.

[0078] The axes of the rotary bearing 21, the external gear bearing 25 and the support shaft 31 are the same. Their common axis is in a vertical state and parallel to the longitudinal section of the hull.

[0079] The support assembly includes a support shaft 31 , a support shaft base 32 , a horizontal slide rail 33 and a slide rail base 34 .

[0080] The support shaft 31 is vertically fixed to the bottom support shaft base 32 and has a vertical limiting groove on its surface.

[0081] The horizontal slide rail 33 is a square slide rail, and its two ends are fixed to the hull through the slide rail base 34, parallel to the hull waterline, and symmetrical about the hull mid-longitudinal section. The center of the upper plane of the horizontal slide rail 33 has a groove for the positioning bead 44 to engage.

[0082] The sliding assembly includes a limiting plate assembly 41 , a sliding ring 42 , a counterweight block 43 and a positioning bead 44 .

[0083] The limit plate assembly 41 is composed of a high limit plate 411 and two low limit plates 412 on the left and right, all of which are rigid rectangular thin plates with the same thickness. The high limit plate 411 is taller than the low limit plate 412. The limit plate assembly 41 is fixedly connected below the slip ring 42 and is symmetrical about the axis of the positioning bead 44.

[0084] During initial installation, the sliding assembly is located in the middle of the horizontal slide rail 33, and the spring 24 pushes the limit cylinder 23 to move upward and squeeze on the high limit piece 411. The high limit piece 411 has a certain width and can be inserted into the limit piece grooves of the left and right limit cylinders 23 at the same time, so that the limit cylinder 23 cannot rotate horizontally. When the sliding assembly overcomes the restriction of the positioning bead 44 and slides to the end of the sinking side and stops, only the low limit piece 412 is located in the groove of the limit cylinder 23 on the sinking side.

[0085] The slip ring 42 is a ball guide sleeve, which is sleeved on the horizontal slide rail 33 and can slide with low rolling resistance but cannot rotate. A threaded hole is provided in the middle of the upper part of the slip ring 42.

[0086] The counterweight block 43 is installed above the slip ring 42 and has a threaded hole in the middle.

[0087] The positioning bead 44 is a threaded positioning bead, which vertically passes through the threaded holes of the sliding ring 42 and the counterweight 43 to achieve the fixed connection of the three. The positioning bead 44 is exposed from the sliding ring 42 and can be engaged with the groove at the top of the horizontal slide rail 33.

[0088] The hull assembly includes a light outer shell 51 , a pressure-resistant cabin 52 , a left dumping group 53 and a right dumping group 54 .

[0089] The light shell 51 has a wing plate 11 recovery channel.

[0090] The left dumping group 53 is located at the lower left side of the boat body, and the right dumping group 54 is located at the lower right side of the boat body.

[0091] The response heel angle of the device refers to the minimum heel angle of the hull at which the sliding assembly overcomes the restriction of the positioning beads 44 and slides. This angle is the same as the maximum heel angle at which the dumping mechanism can dump loads smoothly.

[0092] The method for using the folding wing capable of resisting heeling in emergency floating in this embodiment comprises the following steps:

[0093] S1: Automatic response when the boat tilts greatly and loses depth;

[0094] When the submersible is damaged underwater and water is entering, the vehicle is tilted and falls in depth. If the tilt angle of the hull exceeds the allowable angle of the dumping mechanism, the device will be automatically triggered to respond to the anti-tilt.

[0095] S2: Gravity drive release limit;

[0096] When the hull is greatly heeled, the gravity drives the sliding assembly to overcome the restriction of the positioning bead 44 and slide to the end of the sinking side, thereby releasing the rotation restriction on the raised side wing plate 11 and weakening the rotation restriction force on the wing plate 11 on the sinking side;

[0097] S3: When falling deep, the wing plate on one side is folded to reduce the heel;

[0098] The side wing plate 11 is lifted up and rotated back into the boat body under the driving force of gravity, and energy is stored in the spring system at the same time. When the side wing plate 11 is lifted up and completely rotated into the boat body, the spring 24 pushes the limit cylinder 23 to move up and embed into both sides of the slide rail, so as to completely lock the rotation;

[0099] During the falling process, the side wing plates 11 are lifted and recovered into the hull, and the side wing plates are sunk to generate an anti-heeling moment, thereby reducing the hull heel and facilitating the dumping of loads;

[0100] S4: Automatically recover the wing plate 11 on the other side when floating up;

[0101] During the buoyancy process after dumping the load, the hydrodynamic thrust from top to bottom moves the sinking side wing plate downward, releasing the rotation restriction. Driven by the energy storage spring, the sinking side wing plate 11 rotates and is recovered into the hull. The spring 24 pushes the limit cylinder 23 to move upward and engages with the horizontal slide rail 33 to achieve the locking of the mechanism. During the buoyancy process, the wing plate 11 is recovered into the hull, reducing the buoyancy resistance, increasing the buoyancy speed, and enhancing the stability of the buoyancy posture.

[0102] In actual working process:

[0103] Since the device is installed symmetrically on the left and right, the anti-roll principle is the same for the left and right sides, and this article only takes the right roll as an example for explanation.

[0104] Since the responsive heel angle of the wing plate 11 is the same as the allowable heel angle of the jettison mechanism, which is usually 45° or greater, far exceeding the heel angle of the hull during normal navigation, the horizontal wing cannot be triggered to rotate during normal navigation. The horizontal wing maintains a state perpendicular to the longitudinal section of the hull and is used as a normal stabilizing wing.

[0105] When the submersible is flooded with water in the deep sea unilateral pressure chamber 52, the submersible will sink rapidly with a reduced metacentric height and a large heel state. When the heel angle of the submersible rapidly exceeds the allowable value of the dumping device, the dumping cannot be carried out, threatening the safety of the hull. This device can passively reduce the heel of the hull, making it easier to dump and float.

[0106] Since the response heel angle of the wing plate 11 is the same as the maximum heel angle allowed by the jettisoning mechanism, at this time, the heel angle of the hull is greater than the response heel angle of the wing plate 11 .

[0107] During the movement of the boat, the distance between the center of gravity of the wing 11 and the axis of the rotating shaft 12 is the turning force arm, so the turning force generated by the gravity of the wing 11 is small. The wing 11 drives the limiting cylinder 23 to rotate and squeeze on the limiting plate through the rotating shaft 12, and the friction between the limiting cylinder 23 and the limiting plate is small, which will not significantly interfere with the sliding of the limiting plate.

[0108] When the boat is heeling greatly, the sliding assembly, under the action of its own gravity, breaks through the restriction of the positioning bead 44 and moves to the right end until the sliding ring 42 is stopped by the limit of the slide rail base 34 at the end of the horizontal slide rail 33. At this time, the low limit plate 412 just moves completely to the limit cylinder 23 above the right rudder.

[0109] The limit tube 23 of the left wing is no longer restricted by the limit plate and can rotate freely. Since the center of gravity of the left wing is in front of the rotation axis 12, when the boat is heeling, the leading edge of the wing plate 11 rotates toward the bow of the boat. As the angle between the leading edge of the wing plate 11 and the boat body decreases, the distance between the center of gravity of the wing plate 11 and the rotation axis gradually increases, and the turning force arm gradually increases, so the turning force gradually increases. Since the horizontal wing is long, the turning force is considerable.

[0110] Since the lifting slider 22 cannot rotate horizontally, the left wing plate 11 can only rotate around the lifting slider 22 with the rotating shaft 12 and the outer ring of the steering bearing. Since the rotating bearing 21 adopts a one-way bearing, the left wing can only rotate in one direction toward the hull, and cannot rotate outward after the rotation stops, thereby achieving position locking and folding of the left wing. The greater the hull heel angle, the greater the folding force, and the smaller the angle between the left wing and the longitudinal section of the hull after the folding stops.

[0111] If the heel angle is too large, when the left wing rotates to 90°, the groove of the slide rail on the upper part of the limit cylinder 23 will just turn to be parallel to the slide rail. Under the elastic force of the spring 24, the limit cylinder 23 moves up and automatically embeds into the two sides of the slide rail to completely lock the rotation. At this time, the left wing plate 11 is completely retracted into the hull.

[0112] During the drop, the limit cylinder 23 of the right wing is limited by the low limit plate 412, and the hydrodynamic force on the right wing pushes upward, increasing the pressure on the low limit plate 412. Therefore, the right wing cannot rotate and will not fold during the entire drop. During the rotation and folding process of the left wing, the steering bearing rotates with it, driving the left spring 24 to twist, and through the left and right gears below, it is transmitted to the right spring 24. Both the left and right springs 24 are twisted and elastically deformed, absorbing the left wing rotation force, realizing the storage of rotation force.

[0113] When the submersible is deeply tilted, the left wing of the device is folded into the hull through the above process, and the hydrodynamic force generated by the right wing will form a righting moment. Due to the large negative buoyancy caused by the damage to the cabin, the metacentric height is reduced, and the diving speed is fast. The righting moment generated by the single-side wing plate 11 is considerable, which can effectively reduce the tilt and help achieve load dumping.

[0114] In order to avoid aggravating the heel, the right set of dumping loads 54 can only be discarded first. After the heel angle of the hull decreases, it turns to float up.

[0115] When the submersible floats up, the hydrodynamic force from top to bottom pushes the right wing to compress the spring 24 below and move downward. Since the low limit plate 412 is relatively small in height, the limit cylinder 23 of the right wing only needs a relatively small downward stroke to escape the restriction of the limit plate. Therefore, the rotation of the right wing can be activated at a relatively small hull floating speed. When the limit cylinder 23 of the right wing can rotate freely, the energy stored in the left and right springs 24 will be automatically released, driving the steering bearing, rotating shaft 12 and horizontal wing on the right to rotate. The right wing begins to rotate toward the front of the hull and folds into the hull. Since the hull heel angle when the right wing is folded is smaller than that when the left wing is folded, the energy required is less than the energy stored during the folding process of the left wing, and thus, the recovery of the right wing can be achieved. Since the right steering bearing is a one-way bearing, when the rotation of the right wing stops, the right wing cannot rotate outward, realizing a one-way locking of the position.

[0116] When the right wing is retracted to 90°, the slide rail groove on the upper surface of the right wing's limit cylinder 23 is just parallel to the horizontal slide rail 33. When the right wing is partially folded into the hull, the vertical water flow thrust is reduced, and the limit cylinder 23 of the right wing moves upward under the elastic force of the spring 24, just snapping into the horizontal slide rail 33, achieving complete rotation locking. At this time, the right wing plate 11 is completely retracted into the hull.

[0117] Finally, in the process of floating by dumping, the left and right wing panels 11 are recovered into the hull without power, reducing the floating resistance, increasing the floating speed, and enhancing the stability of the floating posture. In the process of floating to the water surface, the wing panels 11 can be effectively protected from wave loads.

[0118] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.

10. A method for using the folding wing capable of resisting heeling in emergency floating as claimed in claim 1, characterized in that: The steps include: S1: Automatic response when the boat tilts greatly and loses depth; When the submersible is damaged underwater and water is entering, the vehicle is tilted and falls in depth. If the tilt angle of the hull exceeds the allowable angle of the dumping mechanism, the device will be automatically triggered to respond to the anti-tilt. S2: Gravity drive release limit; When the boat body is greatly heeled, the gravity drives the sliding assembly to overcome the restriction of the positioning bead (44) and slide to the end of the sinking side, thereby releasing the rotation restriction on the raised side wing plate (11) and simultaneously weakening the rotation restriction force on the wing plate (11) on the sinking side; S3: When falling deep, the wing plate on one side is folded to reduce the heel; The side wing plate (11) is lifted up and rotated back into the boat body under the driving force of gravity, and energy is stored in the spring system at the same time. When the side wing plate (11) is lifted up and completely rotated into the boat body, the spring (24) pushes the limit cylinder (23) to move upward and embed into the two sides of the slide rail, so as to completely lock the rotation; During the process of falling to a depth, the side wing plates (11) are lifted and recovered into the hull, and the side wing plates are sunk to generate an anti-heeling moment, thereby reducing the hull heel and facilitating the dumping of loads; S4: Automatically recover the wing plate (11) on the other side when floating up; During the process of floating after dumping, the wing plate on the sinking side moves downward due to the hydrodynamic thrust from top to bottom, releasing the rotation restriction. Driven by the energy storage spring, the wing plate (11) on the sinking side rotates and is recovered into the hull. The spring (24) pushes the limit cylinder (23) to move upward and snap into the horizontal slide rail (33), thereby locking the mechanism. During the floating process, the wing plate (11) is recovered into the hull, reducing the floating resistance, increasing the floating speed, and enhancing the stability of the floating posture.
