Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a dual-modal unmanned surface vessel and method with an airbag-insulated retractable side body. Background Technology

[0002] The core performance of watercraft depends on the compatibility of hull structure with load capacity. Currently, the mainstream types are displacement type, planing type, and semi-displacement semi-planing type, all of which have significant limitations, and there is no variable structure solution in the industry that can overcome these limitations.

[0003] Displacement-type vessels are mainly narrow and long, suitable for high loads (such as cargo transportation and carrying heavy detection equipment), stable at low speeds, and their draft is only related to the load. However, water resistance increases dramatically at high speeds, making it difficult to increase speed. Empty vessels cannot achieve high speeds with light loads, resulting in a single mode of operation.

[0004] Planing vessels are designed with a wide hull and shallow draft, making them suitable for empty ships or low-load vessels. They achieve high-speed navigation by relying on planing lift, but at low speeds, the deep draft and high resistance make it difficult to generate effective lift under high loads, and they may even have difficulty navigating. Therefore, they cannot meet the requirements of high loads.

[0005] Semi-displacement, semi-planing vessels are a compromise design. At low speeds and high loads, their resistance is greater than that of displacement vessels, and at high speeds and low loads, their lift is weaker than that of planing vessels. Their performance is even worse under medium loads, making them difficult to adapt to various scenarios.

[0006] As unmanned vessels are applied to marine exploration, emergency rescue, and cargo transportation, the contradictions in demand become apparent: during exploration, high-load vessels require low-speed surveying, while low-load vessels require high-speed relocation; during rescue operations, heavy-load vessels need to transport supplies, while empty vessels need to evacuate quickly; during transportation, fully loaded vessels need to navigate steadily, while empty vessels need to return efficiently. Existing single-mode vessels cannot meet these requirements.

[0007] Currently, unmanned vessels still follow the traditional single-modal design, lacking a dual-modal solution of "a watertight central body for high load capacity and retractable sides for low load gliding". The core problem of "balancing high load capacity at low speed and low load capacity at high speed" has not been solved. Therefore, we propose a dual-modal unmanned watercraft and method with an airbag-type retractable side body. Summary of the Invention

[0008] To address the problem that existing vessels cannot simultaneously achieve stable navigation at low speeds under high loads and high-speed gliding under low loads, and lack a suitable dual-mode structure, the purpose of this invention is to provide: an airbag-lined telescopic side-body dual-mode unmanned surface vessel, comprising an unmanned hull, two symmetrically arranged telescopic side bodies installed on both sides of the unmanned hull, and a limiting block fixedly connected to the side wall of the unmanned hull and abutting the bottom of the telescopic side body;

[0009] The telescopic side body includes a first head-to-tail hinged parallelogram frame, on which a second head-to-tail hinged parallelogram frame that can be telescopic laterally is installed; a foldable telescopic airbag is fixedly sleeved on the inner wall of the first head-to-tail hinged parallelogram frame, and the outer wall of the foldable telescopic airbag near the telescopic side is fixedly connected to the inner wall of the second head-to-tail hinged parallelogram frame; rubber blocks are fixedly connected to the outer walls of the front and rear ends of the first head-to-tail hinged parallelogram frame and the second head-to-tail hinged parallelogram frame.

[0010] Preferably, the first head-and-tail hinged parallelogram frame includes two rectangular horizontal frames and two rectangular side frames. Eight first mounting blocks are fixedly connected to the two ends of the opposite faces of the two rectangular horizontal frames. Sleeves are fixedly connected to the side walls of four of the first mounting blocks on the rectangular horizontal frames. Two arc blocks are fixedly connected to the two ends of the rectangular side frames. Two sleeves on the two rectangular horizontal frames on the same side are rotatably connected to the side walls of the two arc blocks. The arc blocks are located between the two first mounting blocks. A guide limiting groove is provided on the inner wall of the rectangular horizontal frame. The side wall of the upper rectangular horizontal frame is fixedly connected to the side wall of the unmanned vessel. The side walls of the lower rectangular horizontal frame and the rectangular side frames are slidably connected to the side wall of the unmanned vessel. The top surface of the limiting block is in contact with the bottom surface of the lower rectangular horizontal frame.

[0011] Preferably, the second hinged parallelogram frame includes two horizontal plates and two side plates. The horizontal plates are slidably fitted onto the inner wall of the rectangular horizontal frame. A rectangular block is fixedly connected to the bottom of the horizontal plate, and the rectangular block is slidably fitted onto the inner wall of the guide limiting groove. Four second mounting blocks are fixedly connected to opposite ends of the two horizontal plates away from the two rectangular horizontal frames. Four guide rods are fixedly threaded through the side walls of the four second mounting blocks, and the four guide rods are slidably fitted onto the inner wall of the sleeve. The side plates are slidably fitted onto the inner wall of the rectangular side frames, and the upper and lower ends of the side plates away from the rectangular side frames are fixed. A third mounting block is connected, and a guide rod rotatably passes through the side wall of the third mounting block. Several fourth mounting blocks are fixedly connected to the opposite side of the two horizontal plates away from the two rectangular horizontal frames. The side walls of the corresponding two fourth mounting blocks on the two horizontal plates are hinged together with strip plates. A connecting shaft is rotatably passed through the side wall of the strip plate. The end of the connecting shaft away from the strip plate is fixedly connected to the side wall of the foldable telescopic airbag. The outer wall of the foldable telescopic airbag away from the first head-to-tail hinged parallelogram frame is fixedly connected to the side walls of the two horizontal plates and the two side plates.

[0012] Preferably, the foldable telescopic airbag folds inward, and the side wall of the foldable telescopic airbag near the unmanned vessel is slidably connected to the side wall of the unmanned vessel. The foldable telescopic airbag is connected to an air pump located inside the unmanned vessel for inflation and deflation.

[0013] Preferably, the upper and lower ends of the rubber block are folded, and the folded surfaces are fixedly attached to the two rectangular horizontal frames. The folded surface of the rubber block at the end away from the first bow and stern hinged parallelogram frame is fixedly attached to the two horizontal plates. The side wall of the rubber block at the side away from the first bow and stern hinged parallelogram frame is fixedly attached to the side plate. The tilt direction of the side plate is tilted from top to bottom and backward relative to the bow.

[0014] A method for using a dual-modal unmanned surface vessel with an airbag-type retractable side body includes the following steps:

[0015] S1, When the unmanned vessel is navigating by discharging water, the telescopic side bodies on both sides of the unmanned vessel remain in a retracted posture and do not come into contact with the water surface.

[0016] S2, when the unmanned vessel needs to navigate in a high-speed gliding state, the air pump simultaneously inflates the foldable telescopic airbags on both sides, simultaneously opening the first and second bow-and-stern articulated parallelogram frames. The bottom of the telescopic side body is pressed against the limiting block. The telescopic side of the foldable telescopic airbag opens the second bow-and-stern articulated parallelogram frame outward. The second bow-and-stern articulated parallelogram frame extends from the first bow-and-stern articulated parallelogram frame. The sides of the unmanned vessel become wider through the telescopic side body, while the bottom of the telescopic side body is submerged in the water; the unmanned vessel starts in high-speed mode.

[0017] S3, when it is necessary to exit the high-speed gliding state, the air pump controls the foldable telescopic airbag to exhaust air, the second head and tail hinged parallelogram frame retracts inward, and the first head and tail hinged parallelogram frame (1) folds upward, so that the telescopic side body (200) returns to the storage posture.

[0018] To achieve the above objectives, the present invention adopts the following technical solution:

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0020] This invention enables flexible switching between two modes, which can be precisely adapted to different load and navigation requirements. It can maintain stable low-speed navigation in high-load scenarios and achieve high-speed gliding in low-load conditions, thus completely solving the core contradiction that traditional ships with a single mode cannot balance load safety and speed efficiency.

[0021] This invention widens the bottom of the hull by using telescopic side panels on both sides of the hull, thereby increasing the area for taxiing and takeoff. This allows for rapid entry into high-speed taxiing, while also increasing the taxiing support surface, enhancing taxiing lift, reducing the hull's draft, lowering sailing resistance and energy consumption, and significantly improving the stability and propulsion efficiency of high-speed navigation.

[0022] When the ship is taxiing at high speed with low load, the buoyancy of the airbag and the lift of the taxiing work together to further expand the effective support, enhance the balance performance of the hull, avoid the risk of capsizing at high speed, and at the same time reduce the draft of the hull to further improve the taxiing efficiency.

[0023] The airbag of this invention serves as the core support component of the telescopic side body. By leveraging its own elastic properties and combining with a parallelogram frame that folds obliquely upwards, it can effectively buffer the water impact and wave turbulence during high-speed gliding or navigation in complex waters, playing a significant vibration reduction role. This not only avoids the wear or deformation of components caused by direct stress on rigid structures, extending the service life of the telescopic side body and connecting mechanisms, but also reduces the impact of hull vibration on cargo and detection equipment in high-load scenarios, while improving the stability of the hull during high-speed gliding, ensuring the accuracy and navigation safety of unmanned vessels in autonomous operations.

Detailed Implementation

[0031] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0032] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the scope of the invention and therefore have no substantial technical significance.

Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0033] This invention provides a technical solution: a dual-mode unmanned surface vessel with a retractable side body and an airbag liner, comprising an unmanned hull 100, retractable side bodies 200, and limiting blocks 300. The unmanned hull 100 is the main load-bearing structure, with two retractable side bodies 200 symmetrically installed on its two sides. An air pump and control system are installed inside the hull, and the air pump is connected to a foldable retractable airbag 3 via an air pipe. The side walls of the unmanned hull 100, corresponding to the installation positions of the retractable side bodies 200, are provided with suitable sliding grooves to facilitate the folding and unfolding movements of the retractable side bodies 200. The limiting blocks 300 are fixed to the bottom of the side walls on both sides of the unmanned hull 100, and their top surfaces form a retaining engagement with the bottom of the retractable side bodies 200, limiting the downward displacement of the retractable side bodies 200 after unfolding.

[0034] The telescopic side body 200 consists of a first head-to-tail hinged parallelogram frame 1, a second head-to-tail hinged parallelogram frame 2, a foldable telescopic airbag 3, and a rubber block 4.

[0035] The first hinged parallelogram frame 1 consists of two rectangular horizontal frames 101 and two rectangular side frames 102, forming a foldable parallelogram structure.

[0036] Two rectangular horizontal frames 101 are fixed at both ends of opposite sides with first mounting blocks 103, and the side walls of the first mounting blocks 103 on the rectangular horizontal frames 101 are fixed with through sleeves 104.

[0037] The two ends of the rectangular side frame 102 are fixed with arc blocks 105. The two sleeves 104 on the rectangular horizontal frame 101 on the same side are rotatably connected with the arc blocks 105, and the arc blocks 105 are located between the two first mounting blocks 103, so as to realize the hinge connection between the rectangular horizontal frame 101 and the rectangular side frame 102.

[0038] The inner wall of the rectangular horizontal frame 101 is provided with a guide limiting groove 106, which is used to cooperate with the sliding guide of the second frame.

[0039] The upper rectangular frame 101 is fixedly connected to the side wall of the unmanned vessel hull 100, and the lower rectangular frame 101 and rectangular side frame 102 are slidably connected to the side wall of the unmanned vessel hull 100 and can move up and down along the hull sliding groove.

[0040] The second head-to-tail hinged parallelogram frame 2 consists of two horizontal plates 201 and two side plates 202, which are nested inside the first head-to-tail hinged parallelogram frame 1 to form a laterally expandable and contractible structure.

[0041] The horizontal plate 201 is slidably sleeved on the inner wall of the rectangular horizontal frame 101. The rectangular block 203 fixed at the bottom of the horizontal plate 201 is slidably engaged with the guide limiting groove 106 to limit the sliding trajectory of the horizontal plate 201.

[0042] Two horizontal plates 201 are fixed with a second mounting block 204 on the opposite side of one end away from the rectangular horizontal frame 101. A guide rod 205 is fixedly connected to the side wall of the second mounting block 204, and the guide rod 205 is slidably sleeved with the sleeve 104.

[0043] The side plate 202 is slidably sleeved on the inner wall of the rectangular side frame 102. The upper and lower ends of the side plate 202 away from the rectangular side frame 102 are fixed with third mounting blocks 206. The guide rod 205 is rotatably connected to the third mounting block 206 to realize the synchronous movement of the side plate 202 and the guide rod 205.

[0044] Two horizontal plates 201 are fixed with a fourth mounting block 207 on the opposite side away from the rectangular horizontal frame 101. The side walls of the two corresponding fourth mounting blocks 207 are hinged to a strip plate 208. The side wall of the strip plate 208 is rotatably connected to a connecting shaft 209. The connecting shaft 209 is fixedly connected to the side wall of the foldable telescopic airbag 3.

[0045] The outer wall of the stacked telescopic airbag 3 on the side away from the first frame is fixedly connected to the side walls of the two horizontal plates 201 and the two side plates 202, so as to realize the synchronous expansion and contraction of the airbag and the second frame.

[0046] The foldable telescopic airbag 3 adopts an inward folding structure design, with the folding direction being closer to the side of the unmanned hull 100.

[0047] The inner wall of the foldable telescopic airbag 3 is fixedly connected to the inner wall of the first head-to-tail hinged parallelogram frame 1, and the outer wall near the telescopic side is fixedly connected to the inner wall of the second head-to-tail hinged parallelogram frame 2.

[0048] The side wall of the foldable telescopic airbag 3 near the unmanned vessel hull 100 slides and engages with the side wall of the unmanned vessel hull 100. The airbag is connected to the air pump inside the unmanned vessel hull 100. The volume changes are achieved by inflation and deflation, thereby driving the frame to extend and retract. The air pressure of the foldable telescopic airbag 3 can also be controlled by the air pump to meet the requirements.

[0049] Rubber block 4 is fixed to the outer walls of the front and rear ends of the first bow and stern articulated parallelogram frame 1 and the second bow and stern articulated parallelogram frame 2. The rubber block 4 near the bow can guide the impacting water flow obliquely downward to the bottom of the first bow and stern articulated parallelogram frame 1 and the second bow and stern articulated parallelogram frame 2.

[0050] The upper and lower ends of the rubber block 4 are folded, and the folded surfaces are fixedly attached to the two rectangular horizontal frames 101 and the two horizontal plates 201 respectively. The side wall of the rubber block 4 away from the first frame is fixedly attached to the side plate 202 to form a sealed and protective fit.

[0051] The side plate 202 is tilted in a direction that matches the streamlined shape of the bow, and is tilted from top to bottom and rearward relative to the bow to reduce water resistance during navigation.

[0052] This invention achieves two modes—drainage navigation and high-speed gliding—through the retraction and unfolding of the telescopic side body 200. The component matching relationships in each mode are as follows:

[0053] S1, Displacement Navigation Mode:

[0054] When the ship is in a displacement navigation state, the foldable telescopic airbag 3 remains in the deflation state and the airbag remains in a folded storage position.

[0055] When the first and second bow-and-stern articulated parallelogram frames 1 and 2 are kept in a folded and stowed position, the telescopic side body 200 does not contact the water surface, and the ship sails stably by discharging water.

[0056] The displacement navigation mode is generally applicable when the cargo load is relatively large.

[0057] S2, high-speed gliding mode:

[0058] When it is necessary to switch to high-speed gliding mode, the control system starts the air pump to simultaneously inflate the foldable telescopic airbags 3 on both sides.

[0059] After the airbag is inflated, it generates an outward thrust, which pushes the first hinged parallelogram frame 1 to unfold downward. The lower rectangular horizontal frame 101 moves downward along the sliding groove until its bottom surface abuts against the top surface of the limiting block 300, and the first frame remains in a horizontal unfolded state.

[0060] As the airbag continues to inflate, it further pushes the second articulated parallelogram frame 2 outward. The horizontal plate 201 slides along the rectangular horizontal frame 101, the side plate 202 slides along the rectangular side frame 102, and the guide rod 205 extends synchronously along the sleeve 104 until the airbag is fully inflated.

[0061] At this time, the unmanned hull 100 expands its lateral width on both sides through telescopic side bodies 200. The bottom of the telescopic side bodies 200 is submerged in the water to form a wide support surface, and the ship starts to glide at high speed.

[0062] High-speed taxiing mode is generally suitable for empty ships or ships with light cargo loads.

[0063] S3, Mode switching process:

[0064] When it is necessary to exit the high-speed gliding state, the air pump controls the foldable telescopic airbag 3 to exhaust, and the airbag volume gradually shrinks.

[0065] The second hinged parallelogram frame 2 retracts inward under the action of water flow resistance and its own gravity, and the horizontal plate 201 and the side plate 202 simultaneously retract into the first frame.

[0066] After the first bow and stern articulated parallelogram frame 1 loses the support of the airbag, it folds upward, the lower rectangular cross frame 101 moves upward along the sliding groove, the telescopic side body 200 returns to the storage posture, and the ship switches back to the displacement navigation mode.

[0067] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
