Description

Technical Field

[0001] This utility model belongs to the field of rescue equipment technology, and more specifically, it relates to a multifunctional U-shaped intelligent rescue boat. Background Technology

[0002] In maritime rescue scenarios, emergencies such as floods and maritime accidents place rigid demands on rescue equipment for "efficient response, safety assurance, and scenario adaptability." As the complexity of rescue missions increases, single-hull rescue vessels can no longer meet the needs of large-area search and rescue and multi-target collaborative operations. Modular and scalable multi-hull rescue vessels have become an important direction for solving these problems. Through the flexible combination of the main vessel and subsidiary vessels, the rescue range can be expanded, and task division can be achieved (e.g., the main vessel coordinates command, and subsidiary vessels conduct search and rescue in designated areas), thereby improving rescue efficiency.

[0003] Among existing water rescue equipment, while monohull rescue vessels possess basic rescue functions, their rescue range and carrying capacity are limited. For example, the water emergency rescue vessel disclosed in Chinese Patent Publication No. CN215554029U enhances its rescue capabilities through a rescue ladder at the stern and surrounding airbags. However, this vessel is a monohull structure, which cannot flexibly expand the rescue area according to the rescue scenario. When faced with a large number of people trapped or complex aquatic environments, its single rescue efficiency and coverage are insufficient to meet the needs.

[0004] To enhance group rescue capabilities, existing technologies include multi-unit modular rescue platform designs, but these suffer from shortcomings in connection structure and flexibility. Chinese Patent Publication No. CN1290634A discloses a group mutual aid inflatable life raft that combines multiple life rafts using connecting rings, hooks, and ropes to form a large-scale rescue platform. However, its connection method relies on ropes and hooks, resulting in poor structural stability. Furthermore, its fixed assembly form prevents rapid disassembly or reassembly into specific configurations based on rescue needs, making it difficult to adapt to the flexible adjustments required for hull shape in complex rescue scenarios.

[0005] While some multihull vessels possess reconfiguration capabilities, their functional focus is mismatched with rescue scenarios, and they lack dedicated rescue organizations. The reconfigurable aquatic environment measurement vessel system disclosed in Chinese Patent Publication No. CN107979823A adapts to different water areas through the reconfiguration of mother and daughter vessels. However, this system is primarily used for aquatic environment measurement, equipped with an information acquisition module rather than dedicated rescue equipment. Furthermore, the reconfiguration aims to optimize measurement efficiency rather than rescue operations, failing to meet the specialized functions required for personnel rescue and material deployment in water rescue operations.

[0006] To address the capsizing prevention requirements in complex waters, the existing modular structures of multi-hull rescue vessels still have limitations. The multi-section rescue vessel disclosed in Chinese Patent Publication No. CN117002701A uses a rotating connection between end sections and middle sections to form an enclosed structure, aiming to improve capsizing resistance. However, this structure uses a fixed rotating mechanism and electromagnet attraction, resulting in a single modular form (mainly a closed enclosed structure). It cannot be flexibly disassembled into independent hulls or reassembled into other open structures, making it difficult to simultaneously meet the dual requirements of rapid maneuverability and large-scale rescue. Furthermore, it lacks intelligent control and coordination mechanisms for multi-hull collaborative rescue.

[0007] Therefore, it is necessary to develop a multi-functional U-shaped intelligent rescue vessel with a standardized connection structure that can flexibly connect the main vessel and the sub-vessels. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides a multifunctional U-shaped intelligent rescue boat, which is achieved by the following specific technical means:

[0010] Each of the sub-boats is equipped with a connecting block on one side and an i-shaped connecting frame on the other side;

[0011] The inner walls of both the C-shaped connecting frame and the connecting block are provided with mounting holes. Connectors are inserted through the mounting holes between two adjacent hulls to achieve a detachable connection between the C-shaped connecting frame and the connecting block of the adjacent hulls.

[0012] A longitudinally connected assembly is installed between the stern and bow of two adjacent hulls.

A fixing rod is installed on one side of the connecting seat, one end of which extends into the cavity. The fixing rod and the fixing rod sleeve are fixed together by bolts.

[0015] Preferably, the main ship and the multiple sub-ships are all equipped with bottom plates, and each bottom plate is provided with a rescue winding mechanism.

[0016] Preferably, the winding mechanism includes a fixing plate, which is mounted on one side of the upper surface of the base plate. A motor is mounted on one side of the fixing plate, and a transmission rod is mounted on the output end of the motor. One end of the transmission rod is rotatably connected to one side of the base plate.

[0017] The outer wall of the transmission rod is equipped with a main pulley, which is connected to a secondary pulley via a transmission belt. A connecting column is installed on one side of the secondary pulley, and one side of the connecting column is rotatably connected to the fixed plate.

[0023] This utility model, through its U-shaped structure and design allowing for lateral and longitudinal tandem connection, enables rescue vessels to adapt to different environments, including harsh turbulent waters and calm waters, thus improving the versatility and environmental adaptability of the rescue vessels. Specifically, lateral tandem connection is achieved through the cooperation of the U-shaped connecting frame and connecting blocks, while longitudinal tandem connection is achieved by fixing adjacent vessels with bolts through the connecting seat, fixing rod, and fixing rod sleeve. Furthermore, the rotatable sleeve block and rotating shaft enable omnidirectional functionality, enhancing the flexibility of the hull. At the same time, the sub-hulls communicate with each other and work together through a communication module, realizing the collaborative operation of multiple hulls, enhancing rescue capabilities, and enabling more efficient completion of disaster relief and rescue missions.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] like Figures 1 to 5 As shown, a multifunctional U-shaped intelligent rescue boat is provided, comprising multiple hulls. Each hull includes a main hull 1 and multiple sub-hulls 2. At least one side of the main hull 1 is equipped with a U-shaped connecting frame 24. Each sub-hull 2 ​​has a connecting block 25 installed on one side and a U-shaped connecting frame 24 installed on the other side. The inner walls of both the U-shaped connecting frame 24 and the connecting block 25 are provided with mounting holes. Connectors are inserted between adjacent hulls through the mounting holes to achieve a detachable connection between the U-shaped connecting frame 24 and the connecting block 25 of adjacent hulls. A longitudinally connected assembly is provided between the stern and bow of adjacent hulls.

[0033] Specifically, the main ship 1 has an I-shaped connecting frame 24 on at least one side (the side connecting the sub-ships); each sub-ship 2 has a connecting block 25 on one side (the I-shaped connecting frame 24 connecting the preceding hull) and an I-shaped connecting frame 24 on the other side (the connecting block 25 connecting the following hull); the last sub-ship 2 may have only a connecting block 25 on one side (the side away from the main ship).

[0034] The mechanically detachable connection structure between the main vessel and the sub-vessel via the C-shaped connecting frame 24 and connecting block 25, as well as the longitudinal tandem assembly, offers the following advantages: First, the C-shaped connecting frame 24 and connecting block 25 achieve a rigid connection through mounting holes with connecting parts, resulting in higher connection strength and structural stability. This effectively resists the impact of water flow or external forces in complex aquatic environments, avoiding problems such as loosening or detachment that may occur with rope and hook connections. Second, the detachable design is more convenient and efficient, allowing for rapid assembly or disassembly according to the rescue scenario. It flexibly adjusts the hull configuration to meet different rescue ranges and spatial requirements. Existing rope and hook connections are significantly limited in their configuration adjustments, making it difficult to achieve precise combinations of specific structures. Third, the longitudinal tandem assembly further enhances the longitudinal connection rigidity between the stern and bow of adjacent hulls, ensuring overall consistency during multi-hull collaborative operations, reducing relative swaying, and improving the safety and reliability of rescue operations.

[0035] The U-shaped connecting frame and connecting block of this utility model have an interlocking structure that, through the cooperation of the interlocking structure and the connecting parts through the mounting holes, balances the flexibility of the connection (allowing for quick assembly and disassembly to adapt to changes in the scale of the rescue) and the stability (effectively constraining the lateral displacement of the hull through surface contact, solving the problem of easy loosening of simple splicing, such as rope binding). It also allows the sub-boats to be added or removed as needed with the standardized interface, and with the longitudinal series components, it can flexibly switch between multiple scenarios such as "small-scale search and rescue" and "large-scale transfer". At the same time, the U-shaped structure and the design that can be connected laterally and longitudinally allows the rescue boat to adapt to different environments such as harsh rapids and calm waters, improving the versatility and environmental adaptability of the rescue boat.

[0036] like Figure 2 , Figure 3 and Figure 5As shown, the longitudinal tandem assembly includes a mounting base 6, which is installed at the stern of the hull. A connecting rod 7 is rotatably mounted on the inner wall of the mounting base 6. A sleeve block 8 is installed on the outer wall of the connecting rod 7. A rotating shaft 9 is rotatably mounted on one side of the sleeve block 8. A connecting arm 10 is installed on the outer shaft wall of the rotating shaft 9. A fixing rod sleeve 11 is installed at one end of the connecting arm 10. A cavity is provided in the inner wall of the fixing rod sleeve 11. The longitudinal tandem assembly also includes a connecting base 14, which is installed at the bow of multiple sub-boats 2. A fixing rod 12 is installed on one side of the connecting base 14, and one end of the fixing rod 12 extends into the cavity. The fixed rod 12 and the fixed rod sleeve 11 are fixed together by bolts 13. The design allows for both lateral and longitudinal series connection, enabling the rescue vessel to adapt to different environments such as harsh rapids and calm waters, thus improving the versatility and environmental adaptability of the rescue vessel. Specifically, the U-shaped connecting frame 24 and the connecting block 25 can be used for lateral series connection, and the connection between the connecting seat 14, the fixed rod 12 and the fixed rod sleeve 11 can be fixed together by bolts 13 to achieve longitudinal series connection. Furthermore, the rotatable sleeve block 8 and the rotating shaft 9 enable universal function, improving the flexibility of the hull.

[0037] like Figure 1 and Figure 4 As shown, the main vessel 1 and multiple sub-vessels 2 are each equipped with a bottom plate 3. Each bottom plate 3 is equipped with a rescue winding mechanism. The winding mechanism includes a fixed plate 15, which is installed on one side of the upper surface of the bottom plate 3. A motor 16 is installed on one side of the fixed plate 15, and a transmission rod 17 is installed at the output end of the motor 16. One end of the transmission rod 17 is rotatably connected to one side of the bottom plate 3. A main pulley 18 is installed on the outer wall of the transmission rod 17. The main pulley 18 is connected to a secondary pulley 20 via a transmission belt 19. A connecting column 21 is installed on one side of the secondary pulley 20. The side is rotatably connected to the fixed plate 15. A take-up roller 22 is installed on the outer side wall of the connecting column 21. A rescue rope 23 for rescue is set on the outer side of the take-up roller 22. The motor 16 drives the transmission rod 17 to run, thereby driving the main pulley 18 to run, and driving the auxiliary pulley 20 to rotate through the transmission belt 19. Finally, the take-up roller 22 winds up the rescue rope 23. By releasing the rescue rope 23, the rescuer can put the rescue rope 23 on the target object, and then tighten it through the winding mechanism to achieve traction or fixation of the target. It is suitable for various scenarios such as rescuing floating objects and fixing the position of the hull.

[0038] like Figure 1As shown, communication modules 5 are installed on the upper surface of the bottom plate 3 on multiple sub-boats 2, and a central controller 4 is installed on the upper surface of the bottom plate 3 on the main boat 1. Multiple communication modules 5 are electrically connected to the central controller 4. Through multiple communication modules 5, the boats can communicate with each other to achieve joint rescue. Multiple communication modules 5 are electrically connected to the central controller 4. The central controller 4 can uniformly control the movement status and equipment operation of the sub-boats 2, so that multiple sub-boats 2 can work together to improve rescue efficiency.

[0039] The working principle of this embodiment is as follows:

[0040] The main vessel 1 is equipped with C-shaped connecting frames 24 on both sides, and the subsidiary vessel 2 is equipped with a connecting block 25 on one side and a C-shaped connecting frame 24 on the other side. The mounting holes on these C-shaped connecting frames 24 and connecting blocks 25 are used to pass through bolts, pins and other connecting parts, so that the C-shaped connecting frames 24 and connecting blocks 25 of adjacent hulls or the C-shaped connecting frames 24 can be detachably connected. Through the corresponding connecting parts, the adjacent hulls are connected laterally, thereby realizing lateral series connection to adapt to the rescue needs of different waters.

[0041] A mounting base 6 is installed at the stern of the hull, with a connecting rod 7 rotatably mounted on its inner wall. A sleeve block 8 is installed on the outer wall of the connecting rod 7. A rotating shaft 9 is rotatably mounted on one side of the sleeve block 8. A connecting arm 10 is installed on the outer shaft wall of the rotating shaft 9. A fixing rod sleeve 11 is installed at one end of the connecting arm 10, and its inner wall has a cavity. A connecting base 14 is installed at the adjacent end of the hull, with a fixing rod 12 installed on one side and one end extending into the cavity. The fixing rod 12 and the fixing rod sleeve 11 are then fixed by bolts 13 to achieve longitudinal connection. The rotatable design of the sleeve block 8 and the rotating shaft 9 enables universal movement and improves the hull's flexibility in complex waters.

[0042] The main vessel 1 and multiple sub-vessels 2 are each equipped with a bottom plate 3. Each bottom plate 3 is equipped with a rescue winding mechanism. A fixed plate 15 is installed on one side of the upper surface of the bottom plate 3, and a motor 16 is installed on one side of the fixed plate 3. A transmission rod 17 is installed at the output end of the motor 16. One end of the transmission rod 17 is fixed to one side of the bottom plate 3. A main pulley 18 is installed on the outer wall of the rod, and it is connected to the auxiliary pulley 20 through a transmission belt 19. A connecting column 21 is installed on one side of the auxiliary pulley 20, and its side is rotatably connected to the fixed plate 15. A take-up roller 22 is installed on the outer wall, and a rescue rope 23 is set on the outer side. When a rescue is needed, the motor 16 drives the transmission rod 17 to run, which in turn drives the main pulley 18 to run. The transmission belt 19 drives the auxiliary pulley 20 to rotate, which in turn causes the take-up roller 22 to wind up or unwind the rescue rope 23. Rescuers can use the rescue rope 23 to wrap around the target object and tighten it through the winding mechanism to achieve traction or fixation of the target. This method is suitable for a variety of rescue scenarios.

[0043] Communication modules 5 are installed on the upper surface of the bottom plate 3 of multiple sub-boats 2, enabling communication between the boats and achieving joint rescue. A central controller 4 is installed on the upper surface of the bottom plate 3 of the main boat 1. Multiple communication modules 5 are electrically connected to the central controller 4. The central controller 4 can uniformly control the movement status and equipment operation of the sub-boats 2, enabling multiple sub-boats 2 to work together and improve rescue efficiency.

[0044] In some embodiments, the communication module 5 is a wireless communication module, including but not limited to one or more combinations of a 4G communication module, a 5G communication module, a Bluetooth module, or a WiFi module.

[0045] In some embodiments, the communication module 5 includes a signal enhancement unit for improving the strength of communication signals in complex aquatic environments.

[0046] In some embodiments, the communication module 5 has an encrypted transmission function for encrypting rescue information transmitted between vessels.

[0047] In some embodiments, the communication module 5 includes a status feedback submodule, which is used to feed back the equipment operating status information of the sub-ship 2 to the central controller 4 in real time.

[0048] In some embodiments, the central controller 4 is electrically connected to the motors 16 on each of the sub-boats 2 and the main boat 1 via wires. The central controller 4 is used to send control signals to the motors 16 to control the start, stop and forward / reverse rotation of the motors 16.

[0049] In some embodiments, the central controller 4 includes a touch screen, which is electrically connected to the control unit of the central controller 4, and is used to display the operating parameters and operation command inputs of each sub-ship 2.

[0050] In some embodiments, the central controller 4 is provided with a waterproof housing, which is fixedly connected to the bottom plate 3 of the main ship 1 by bolts, and the surface of the waterproof housing is provided with a sealed interface for wiring.

[0051] In some embodiments, the central controller 4 includes a storage unit electrically connected to the control unit for storing communication records and equipment operation data during the rescue process.

[0052] In some embodiments, the central controller 4 is electrically connected to the power system of the main ship 1, and can adjust the sailing speed and direction of the main ship 1 by controlling the power system.

Many modifications and variations will be apparent to those skilled in the art.
