Description

Technical Field

[0001] This invention belongs to the field of shipbuilding technology, and specifically discloses a ship with a deformable deck structure. Background Technology

[0002] Currently, when conventional patrol vessels perform maritime patrol and rescue missions, their open decks serve as the core operating platform, and in actual use, the following significant structural and functional defects have been exposed.

[0003] The existing patrol boat decks are rigid, fixed structures with a limited spatial configuration. During missions, when temporarily transporting and operating large, heavy specialized rescue or engineering equipment, the fixed deck layout often restricts equipment placement and movement routes. This is especially true in narrow or long areas such as the bow and stern, where equipment movement and operation are extremely difficult, reducing operational efficiency. Secondly, the existing decks primarily rely on pre-set slopes and fixed deck drainage holes (side drains) for drainage. In extreme situations with large waves crashing onto the deck, the drainage capacity (including volume and speed) of the fixed drainage holes may not be sufficient to drain the accumulated water in time. Large amounts of seawater accumulate on the deck and spread along its length, easily flowing towards hatches, thresholds, or ventilation openings leading to the interior of the ship, posing a serious risk of flooding. This could damage internal equipment and electrical systems, and directly endanger the ship's navigational safety and reserve buoyancy.

[0004] Therefore, the present invention proposes a ship with a deformable deck structure to solve the above-mentioned defects. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the background art, and to propose a ship with a deformable deck structure, including a ship hull, a cable reel winder, and a skid steer. The surface of the ship hull deck is provided with a deformable water-blocking and diversion mechanism. A column is vertically installed above the ship hull deck. The cable reel winder is fixedly installed above the column. A traction cable is wound inside the cable reel winder, and a connecting component is provided at the end of the traction cable away from the cable reel winder. The traction cable is connected to the top of the skid steer through a sliding hoist. Icebreaking mechanisms are provided on both sides inside the skid steer. A lifting and lowering wave-blocking mechanism is provided at the railings on both sides of the ship hull near the deck.

[0006] In the above technical solution, the deformation water-blocking and diversion mechanism further includes a sealing strip fixedly installed on the upper surface of both sides of the deck, a corner plate fixedly installed at one end of the sealing strip that is close to each other, a connecting block fixedly installed on the outer surface of one side of the column, a driving mechanism provided on both sides inside the connecting block, and a flow-blocking rubber plate provided below the driving mechanism.

[0007] In the above technical solution, the driving mechanism further includes a third hydraulic cylinder fixedly installed inside one side of the connecting block. A locking block is fixedly installed at the telescopic end of the third hydraulic cylinder. A rack is fixedly installed at the lower end of the locking block. A gear is meshed with the rack below. A rotating shaft is fixedly inserted inside the gear. L-shaped blocks are fixedly installed at both ends of the rotating shaft. The lower ends of the two L-shaped blocks are fixedly connected to the upper surface of the baffle rubber plate. One end of the rotating shaft is rotatably engaged with the inside of the angle plate.

[0008] In the above technical solution, the connecting assembly further includes an electric telescopic rod fixedly installed above one end of the ship's hull, with a screw cylinder fixedly installed at the telescopic end of the electric telescopic rod, and the end of the traction cable away from the cable reel is fixedly connected to the outer wall of the screw cylinder.

[0009] In the above technical solution, the sliding hoist further includes a sliding ring that is slidably fitted outside the traction cable. A hanging plate is installed below the outside of the sliding ring. Connecting ropes are fixedly installed at both ends of the bottom of the hanging plate, and the two connecting ropes are respectively connected to the top of the sliding vehicle.

[0010] In the above technical solution, the ice-breaking mechanism further includes a strip groove opened above the sliding steer, and a second hydraulic cylinder is fixedly installed on both sides above the sliding steer and close to the strip groove. The telescopic ends of the second hydraulic cylinder are jointly installed with a crossbar. The crossbar is connected to a mounting frame through a connecting rod fixedly installed on the lower surface. The mounting frame is provided with a crushing component. Heating plates are fixedly installed at both ends of the bottom of the sliding steer.

[0011] In the above technical solution, the crushing component further includes a rotating drum rotatably installed inside the mounting frame. Multiple sleeves are fixedly fitted on the outside of the rotating drum. Scraping teeth are installed at equal intervals along the circumferential direction on the outside of the multiple sleeves. A motor is fixedly installed on the outside of one end of the mounting frame. The output shaft of the motor extends into the inside of the mounting frame and is fixedly connected to one end of the rotating drum.

[0012] In the above technical solution, the lifting and wave-blocking mechanism further includes a first hydraulic cylinder fixedly installed at the railing on the side of the ship's hull near the deck. A fixed plate is fixedly installed at the telescopic end of the first hydraulic cylinder. A ship cofferdam is fixedly installed on one side of the fixed plate. Multiple sets of guide grooves are opened on the outer surface of the ship cofferdam. Guide rods are symmetrically installed above the railing, and sliding rods are slidably fitted on the outside of each guide rod. The lower end of the sliding rod is fixedly connected to the upper surface of the ship cofferdam.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention utilizes a skid trolley mounted on deck rails, combined with an aerial hoisting system consisting of columns, a skid cable retractor, and a traction cable, to achieve flexible movement and precise transport of equipment above deck. It eliminates the constraints of fixed deck layouts, enabling convenient placement, relocation, and operational procedures even in narrow or long areas such as the bow and stern. This effectively solves the pain point of difficult equipment transport and significantly improves the operational efficiency of maritime patrol, rescue, and other missions.

[0014] 2. By incorporating a lifting and lowering wave-damping mechanism, the cofferdam can be quickly raised in adverse sea conditions, effectively blocking and reducing the amount of seawater that waves can reach the deck. Secondly, the core deformation-type water-retaining and diversion mechanism can control the deflector rubber plate to flip to one side, cooperating with the side seals and corner plates to actively create a temporary diversion channel on the deck surface. This channel can quickly guide water accumulated on the deck (especially water that easily accumulates near the cabin entrances) to predetermined large drainage outlets or the sides, greatly accelerating the deck drainage speed and actively preventing the risk of water spreading on the deck and entering the cabins, thereby ensuring the safety of the ship's interior and its navigational stability.

[0015] 3. By installing icebreaking mechanisms on the skid steer vehicle, the ship can move to the required work location and activate the icebreakers and heating plates on it. This enables the ship to clear and prevent localized ice buildup on the deck in icy or cold water areas. It also enhances the ship's deck maintenance and operation capabilities in special environments, expands the functional dimensions of a single deck platform, and improves the ship's multi-tasking adaptability and environmental adaptability.

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-8 The vessel shown includes a deformable deck structure, comprising a hull 1, a cable retractor 6, and a skid steer 18. The deck surface of the hull 1 is provided with a deformable water-blocking and diversion mechanism. A column 12 is vertically installed above the deck of the hull 1. The cable retractor 6 is fixedly installed above the column 12. A traction cable 4 is wound inside the cable retractor 6, and a connecting component is provided at the end of the traction cable 4 away from the cable retractor 6. The traction cable 4 is connected to the top of the skid steer 18 through a sliding hoist. Icebreaking mechanisms are provided on both sides inside the skid steer 18. A lifting and lowering wave-blocking mechanism is provided at the railings on both sides of the hull 1 near the deck. In this embodiment, the main body 1 is a near-shore patrol vessel, the column 12 is a steel pipe welded to the rear end of the deck, and the traction cable 4 is a steel wire rope with one end wound inside the cable reel 6 and the other end connected to the connecting assembly. The cable reel 6 can be adapted to use on decks of different lengths. The cable reel 6 consists of a self-locking ratchet assembly, a wheel, an electric motor, a sensor, and other structures. The deformable water-blocking and diversion mechanism is directly installed on the deck surface to cope with the accumulation of water from incoming waves. It can actively change the local deck shape to guide water flow. The coordinated operation of the cable reel 6 and the skid steer 18 enables three-dimensional transport on the deck. The icebreaking mechanism of the skid steer 18 gives the ship the ability to maintain its deck in ice-covered environments. The lifting wave-blocking mechanisms on both sides of the deck serve as wave protection structures, which can be raised to physically block waves from entering. The combined operation of these mechanisms enables the ship to dynamically adapt to various mission scenarios, from heavy equipment transport and drainage in severe sea conditions to operations in ice-covered areas.

[0021] The deformation-resistant water-diverting mechanism includes seals 10 fixedly installed on the upper surfaces of both sides of the deck. Angle plates 29 are fixedly installed at the ends of the seals 10 that are close to each other. A connecting block 31 is fixedly installed on the outer surface of one side of the column 12. A drive mechanism is provided on both sides inside the connecting block 31. A flow-blocking rubber plate 8 is provided below the drive mechanism. The drive mechanism includes a third hydraulic cylinder 30 fixedly installed on one side inside the connecting block 31. A locking block 28 is fixedly installed at the telescopic end of the third hydraulic cylinder 30. A rack 34 is fixedly installed at the lower end of the locking block 28. A gear 35 is meshed and connected below the rack 34. A rotating shaft 32 is fixedly inserted inside the gear 35. L-shaped blocks 33 are fixedly installed at both ends of the rotating shaft 32. The lower ends of the two L-shaped blocks 33 are fixedly connected to the upper surface of the flow-blocking rubber plate 8. One end of the rotating shaft 32 is rotatably engaged with the inside of the angle plate 29. In this embodiment, the seal 10 is made of neoprene rubber strip. The two sets of seals 10 are located on both sides of the baffle plate 8, forming a V-shaped water-blocking boundary. When seawater rushes into the deck, in order to prevent seawater from rushing into the compartment at the rear of the deck, the telescopic end of the third hydraulic cylinder 30 extends and pushes the locking block 28 and the rack 34 to move horizontally. The rack 34 meshes and drives the gear 35 to rotate. The gear 35 drives the rotating shaft 32 to rotate synchronously. The L-shaped blocks 33 at both ends of the rotating shaft 32 flip with the rotating shaft 32, causing the baffle plate 8 to flip around the connection point. Therefore, the baffle plate 8 itself deforms, which can make the baffle plate 8 flip and lift to one side to form a diversion slope, diverting the seawater on the deck surface to both sides.

[0022] The connecting assembly includes an electric telescopic rod 2 fixedly installed above one end of the ship's hull 1. A screw cylinder 3 is fixedly installed at the telescopic end of the electric telescopic rod 2. The end of the traction cable 4 away from the cable retractor 6 is fixedly connected to the outer wall of the screw cylinder 3. In this embodiment, before transporting the equipment, the electric telescopic rod 2 is activated to extend or retract its telescopic end, pushing the screw cylinder 3 to move until the screw cylinder 3 is in the same straight line as the cable reel 6 on the column 12 or is lower than the height of the column 12. Then, the cable reel 6 is activated to reel in the traction cable 4 until the traction cable 4 is tensioned (the tension is controlled by the built-in sensor of the cable reel 6), forming a stable cable track, which provides a foundation for the movement of the sliding steer 18.

[0023] The sliding hoist includes a sliding ring 7 that is fitted onto the outside of the traction cable 4. A hanging plate 11 is installed below the outside of the sliding ring 7. Connecting ropes 21 are fixedly installed at both ends of the bottom of the hanging plate 11. The two connecting ropes 21 are respectively connected to the top of the sliding tractor 18. In this embodiment, when transferring equipment on the deck, after placing the equipment above the skid steer 18, the slip ring 7 is manually pushed to slide along the traction cable 4. The slip ring 7 drives the lower hanging plate 11 to move synchronously, and the hanging plate 11 pulls the skid steer 18 to move smoothly through the connecting rope 21.

[0024] The ice-breaking mechanism includes a strip groove opened above the sliding trolley 18. Second hydraulic cylinders 22 are fixedly installed on both sides above the sliding trolley 18 and close to the strip groove. The telescopic ends of the second hydraulic cylinders 22 are connected to a crossbar 20. The crossbar 20 is connected to a mounting frame 17 through a connecting rod 23 fixedly installed on the lower surface. The mounting frame 17 is equipped with a crushing component. Heating plates 19 are fixedly installed at both ends of the bottom of the sliding trolley 18. The crushing component includes a rotating drum 27 rotatably installed inside the mounting frame 17. Multiple sleeves 24 are fixedly sleeved on the outside of the rotating drum 27. Scraping teeth 26 are installed at equal intervals along the circumference on the outside of the multiple sleeves 24. A motor 25 is fixedly installed on the outside of one end of the mounting frame 17. The output shaft of the motor 25 extends into the inside of the mounting frame 17 and is fixedly connected to one end of the rotating drum 27. In this embodiment, during ice-covered operations, the second hydraulic cylinder 22 drives the crossbar 20 to descend. The crossbar 20, through the connecting rod 23, lowers the mounting frame 17 to the ice surface. Then, the motor 25 is started to rotate the rotating drum 27. The rotating drum 27 drives the sleeve 24 and the scraper teeth 26 to rotate synchronously. When the tip of the scraper teeth 26 contacts the ice layer, it breaks the surface of the ice layer through impact force. The subsequently rotating scraper teeth 26 further shear the ice fragments until the ice layer is broken. At the same time, the heating plate 19 is activated to heat the area around the skid steer 18, ensuring that the skid steer 18 can move while also heating and melting the thin ice layer. After the operation is completed, the second hydraulic cylinder 22 is reset, the mounting frame 17 is retracted into the slot, and the heating plate 19 is turned off. It should be noted that the power supply can be connected to an external power source for the main body of the ship 1, or a backup battery can be added to the skid steer vehicle 18.

[0025] The lifting and wave-blocking mechanism includes a first hydraulic cylinder 13 fixedly installed at the railing on the side of the ship's hull near the deck. A fixed plate 15 is fixedly installed at the telescopic end of the first hydraulic cylinder 13. A ship cofferdam 14 is fixedly installed on one side of the fixed plate 15. Multiple sets of guide grooves 16 are opened on the outer surface of the ship cofferdam 14. Guide rods 5 are symmetrically installed above the railing, and sliding rods 9 are slidably fitted on the outside of each guide rod 5. The lower end of the sliding rod 9 is fixedly connected to the upper surface of the ship cofferdam 14. In this embodiment, the first hydraulic cylinder 13 pushes the fixed plate 15 and the ship cofferdam 14 to move in the vertical direction. The ship cofferdam 14 can extend above the ship railing and be raised in height. At the same time, when the waves hit the outer surface of the ship cofferdam 14, the external guide groove 16 can longitudinally divide the seawater flow and guide it to both sides, significantly reducing the pressure of the water flow on the front of the baffle and improving the wave blocking efficiency and structural durability.

[0026] To ensure the smoothness of the lifting process, a guide rod 5 is installed above the ship railing, which forms a sliding pair with the slide rod 9 fixed on the baffle, effectively preventing the ship railing baffle 14 from shaking or getting stuck under the impact of waves.

[0027] Working principle: When heavy or large equipment needs to be transferred on the deck, the operator first activates the electric telescopic boom 2, causing its telescopic end to extend the screw cylinder 3 and the end of the traction cable 4, so as to connect with the equipment to be transferred or adjust the traction starting point. Then, the cable reel 6 is controlled to retract or extend the traction cable 4 according to the height of the electric telescopic boom 2, so that the traction cable 4 is taut. Then, the equipment is placed on top of the sliding strafe 18. With the connection of the sliding spreader, the sliding strafe 18 moves on the deck, realizing efficient and flexible scheduling of equipment in a two-dimensional plane, which greatly optimizes the space utilization of the fixed deck layout.

[0028] In the event of rough seas and the risk of seawater reaching the deck, the first hydraulic cylinder 13, installed at the ship's railing, extends, pushing the fixing plate 15 to lift the cofferdam 14 upwards along the outside of the guide rod 5. The raised cofferdam 14 effectively increases the ship's freeboard, acting as a physical barrier to significantly block and reduce the amount of seawater directly impacting the deck. The guide grooves 16 on the surface of the cofferdam 14 help direct the incoming seawater flow to both sides, reducing the frontal impact on the cofferdam. If seawater still overflows the cofferdam 14, especially if there is a tendency for accumulated water to spread towards the cabin entrance, the deformation-resistant water-diverting mechanism is activated. Specifically, the third hydraulic cylinder 30 within the connecting block 31 extends, pushing the locking block 28 and the toothed rod 34 to one end. The rack 34 drives the meshing gear 35 to rotate. The gear 35 drives the L-shaped blocks 33 at both ends to rotate synchronously through the shaft 32, thereby causing the baffle plate 8, which is fixedly connected to the lower end of the L-shaped block 33, to flip to one side. Since the L-shaped block 33 is close to one side edge of the baffle plate 8, the rear end of the baffle plate 8 undergoes adaptive deformation when flipping. The baffle plates 8 on both sides can then cooperate with the seals 10 and corner plates 29 on the deck to temporarily construct a V-shaped drainage channel with higher ends on the deck surface. Under the guidance of the slope of this artificial structure, the water on the deck will quickly gather and flow along the channel to the preset large drain outlet or be directly diverted overboard, thereby realizing the active and rapid guidance of the water flow and avoiding the risk of water flowing disorderly on the deck and flooding into the cabin. When navigating in cold waters and ice forms on the deck surface, the skid steer 18 moves and the heating plate 19 inside the skid steer 18 is activated to heat the bottom of the vehicle and the surrounding deck area, softening the ice.

[0029] For thicker ice layers, the second hydraulic cylinder 22 is controlled to push the crossbar 20 and the mounting frame 17 down, so that the breaking parts inside the mounting frame 17 come into contact with the ice surface. The motor 25 drives the rotating drum 27 and the multiple sets of scraping teeth 26 on the outside of the sleeve 24 to rotate at high speed. The rotating scraping teeth 26 impact and scrape the ice surface to achieve mechanical ice breaking. After the ice layer is cleared, patrol personnel can move safely on the deck.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
