Description

Technical Field

[0001] The utility model belongs to the field of unmanned boat recovery, and in particular relates to a double-hanging-point unmanned boat retracting and launching structure. Background Art

[0002] With the rapid advancement of modern science and technology, unmanned boats, as emerging offshore operation platforms, have shown great application potential in many fields. With their autonomous navigation, remote control, high mobility and ability to adapt to harsh environments, unmanned boats are widely used in many key fields such as ocean observation, environmental monitoring, maritime security patrols, military reconnaissance, search and rescue operations, marine mapping, and logistics and transportation. Especially when performing complex tasks or in dangerous environments where it is difficult for humans to directly intervene, unmanned boats can provide safe, efficient and cost-effective solutions.

[0003] In recent years, unmanned boat swarm technology has become a hot research frontier. This technology allows multiple unmanned boats to work together, and through networked communications and distributed intelligent algorithms, it can achieve efficient task allocation and execution, greatly enhancing the information collection, processing and response capabilities of the unmanned boat system. Swarm operations can not only expand the scope of operations, but also improve the flexibility, reliability and completion of tasks through the complementarity and collaboration between multiple boats, such as synchronous observation in large areas of sea, coordinated search and rescue operations, or the execution of complex tactical formations.

[0004] Most of the existing launching and retracting systems are designed for the launching and retracting of single-body unmanned boats. They rely on a single lifting point, which limits the number of unmanned boats operating at the same time. They also occupy a large deck area, affecting the other functional layouts of the mother ship. Single-point lifting requires precise alignment and the operation process is cumbersome. Especially when the wind and wave conditions are poor, the difficulty and risk increase significantly. In severe sea conditions, single-point lifting is easily affected by waves, causing damage to the unmanned boat or interruption of operation, affecting the smooth progress of the overall mission. Faced with the rapid deployment needs of large-scale unmanned boats, traditional launching and retracting methods are difficult to meet the requirements of time-sensitive tasks.

[0005] At the same time, most of the existing mother ship designs did not foresee the need for the deployment of unmanned boat clusters, and most ships do not have the ability to transform out of the dock; at the same time, because the structure of the stern rudder shaft spacing is fixed and there is a helicopter deck or superstructure at the stern, the hull itself does not have the conditions for retrofitting the stern slide. This leads to a clear mismatch between its structural diversity and the standardization of the unmanned boat carrying system. In particular, the structure of most ships cannot be transformed out of the dock, which limits the possibility of efficient and large-scale unmanned boat loading. Utility Model Content

[0006] The utility model aims to provide a double-hanging-point unmanned boat launching and retracting structure, which utilizes the hull deck area or cabin space to carry out integrated arrangement and simultaneously launch and retract multiple unmanned boats through the mother ship's side through the double hanging points.

[0007] In order to achieve the above-mentioned purpose, the specific technical scheme of a double-hanging-point unmanned boat retracting and launching structure of the utility model is as follows:

[0008] A double-hanging-point unmanned boat retracting and launching structure comprises a frame structure for placing the unmanned boat, a retracting and launching structure for transporting the frame structure, and a hydraulic winch;

[0009] The retractable structure is arranged on both sides of the frame structure, and includes a base, a boom rotatably connected to the base, and a retractable drive device for driving the boom to rotate relative to the base;

[0010] The retractable drive device comprises a fixed end and a telescopic end, wherein the fixed end is connected to the base, and the telescopic end is connected to the boom, and the boom is driven to rotate relative to the base by the telescopic end extending relative to the fixed end;

[0011] The sling of the hydraulic winch is arranged along the boom and connected to the frame structure. The boom rotates to realize the movement of the frame structure between the mother ship and the water surface. The hydraulic winch retracts and extends the sling to realize the lifting and lowering of the frame structure relative to the retractable structure.

[0012] As a further improvement of the present invention, the fixed end is rotatably connected to the base.

[0013] As a further improvement of the present invention, the frame structure includes a frame body with an opening on one side, a closing frame arranged at the opening of the frame body and rotatably connected to the frame body, and a rotation driving device driving the closing frame to rotate relative to the frame body; the rotation of the closing frame realizes the closing and opening of the frame body.

[0014] As a further improvement of the utility model, a plurality of retractable seats are arranged in the frame body, and a plurality of adjacent retractable seats form a retractable seat group for retracting and releasing the unmanned boat, and a lifting groove is arranged between the retractable seats in the same group; the storage equipment extends out or retracts from the lifting groove to realize the taking out or placing of the unmanned boat on the retractable seat.

[0015] As a further improvement of the utility model, a plurality of corner pulley structures are arranged on the boom, and the sling is connected to the frame body after being turned by the corner pulley structure.

[0016] As a further improvement of the present invention, a lifting lug is provided on the upper end surface of the frame body, and the lifting lug cooperates with the hook at the front end of the sling to achieve the connection between the hydraulic winch and the frame body.

[0017] As a further improvement of the utility model, a pin-type locking structure is provided on the upper surface of the retractable seat, and the unmanned boat is fixed in the frame body by inserting the corresponding part of the unmanned boat.

[0018] As a further improvement of the utility model, a lashing structure is provided on the retractable seat, and the unmanned boat is fixed to the retractable seat by lashing ropes.

[0019] As a further improvement of the utility model, it also includes a control system and a power source, wherein the control system realizes the electric control of the retractable structure, and the power source provides hydraulic drive for the retractable structure.

[0020] Beneficial effects:

[0021] The dual-hanging-point design enables the deployment or recovery of two unmanned boats at the same time, greatly shortening the operation cycle. Compared with the single-hanging-point system, it significantly improves the rapid response capability of the unmanned boat cluster and the execution efficiency of large-scale tasks.

[0022] The combination of the hydraulic winch and the precise boom rotation design in the retractable structure ensures the stability of the unmanned boat during lifting and transportation, and maintains safe and stable operation even in severe sea conditions, reducing the potential risk of damage to the unmanned boat.

[0023] The retractable seat group design inside the frame structure and the rotating closed frame realize the compact storage and quick access of the unmanned boat, improving the space utilization of the mother ship. At the same time, the design facilitates the flexible configuration of different types of unmanned boats and enhances the system's adaptability to diverse tasks.

[0024] The integrated control system enables precise control of the entire retraction and deployment process, including boom rotation, frame lifting and locking / unlocking of the unmanned boat, which improves operation accuracy, reduces manual intervention, and makes operation more convenient and efficient.

[0025] Through the standardized design of the lifting seat, pin-type locking structure and tying device, the retractable and launching structure can be compatible with unmanned boats of different sizes and types, improving the versatility and interchangeability of the system and reducing maintenance and upgrade costs.

[0026] Through optimized design, the double-lifting-point retractable and launching structure reduces the strict requirements on the mother ship's load capacity, stability and spatial layout, allowing ships of more types and sizes to be used as effective unmanned boat mother ships, expanding the application scope of unmanned boat cluster operations.

[0027] To sum up, the double-lifting-point unmanned boat retracting and launching structure provided by the utility model not only solves the problems in the prior art regarding low operating efficiency, complex operation and poor versatility of unmanned boat clusters, but also lays a solid technical foundation for the wide application of unmanned boat clusters in marine scientific research, monitoring, security and other fields through intelligent and modular design.

DETAILED DESCRIPTION

[0033] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0034] Implementation example:

[0035] like Figure 1 As shown, a double-hanging-point unmanned boat retracting and launching structure is arranged on the deck of a mother ship, and includes a frame structure 100, a retracting and launching structure 200, a hydraulic winch 300, a control system 400 and a power source 500. The frame structure 100 is erected on both sides of the retracting and launching structure 200, and the sling 310 of the hydraulic winch 300 passes through the retracting and launching structure 200 and is connected to the top of the frame structure 100. The unmanned boat 700 is centrally stored through the storage device 600, and is moved into the frame structure 100 through the storage device 600 when released, and is moved out of the deck to the water surface through the retracting and launching structure 200. The hydraulic winch 300 controls the lifting and lowering of the frame structure 100 above the water surface by retracting the sling 310, and the unmanned boat 700 is released or recovered after the frame structure 100 falls into the water.

[0036] like Figure 2 As shown, the frame structure 100 includes a C-shaped frame body 110 for placing the unmanned boat 700, a closing frame 120 for closing the unmanned boat 700 in the frame body 110, and a rotation drive device 130 for driving the closing frame 120 to rotate relative to the frame body 110. A plurality of retractable seats 111 are provided at the bottom of the frame body 110, two retractable seats 111 form a group for placing the unmanned boat 700, and a lifting groove 113 is provided between the retractable seats 111 in the same group. The translation track of the storage device extends to the bottom of the lifting groove 113, and the lifting and lowering of the storage device in the lifting groove 113 realizes the removal and placement of the unmanned boat 700 in the frame body 110. In this embodiment, two groups of retractable seats 112 are provided to realize the simultaneous retraction and release of two unmanned boats.

[0037] At the same time, the upper end surface of the retractable seat 111 is also provided with a pin-type locking structure 140 and a tying structure 150, which fix the unmanned boat in the frame body by means of pins and tying, so that the retractable seat can be compatible with unmanned boats of different sizes and types, reducing maintenance and upgrade costs, and better coping with the retraction and deployment in strong winds and waves at sea.

[0038] like Figure 3 As shown, the retractable structure 200 includes a base 210 fixed on the deck, a boom 220 rotatably connected to the base 210 at the lower end, and a retractable drive device 230 connected to the base 210 at a fixed end 231 and the boom 220 at a telescopic end 232. The hydraulic winch 300 is arranged on the deck beside the base 210, and the sling 310 passes through a plurality of corner pulley structures of the boom 220 and is connected to the lifting lug at the upper end of the frame body 110. In this embodiment, the retractable drive device 230 is an oil cylinder structure, the fixed end 231 is a cylinder body, and the telescopic end 232 is a piston rod. The telescopic end 232 telescopically drives the boom 220 to rotate relative to the base 210 and extend to the water surface outside the mother ship. At the same time, the hydraulic winch 300 rotates, tightens or loosens the sling 310, and cooperates with the boom 220 to move the frame structure 100 out of the deck to achieve lifting.

[0039] like Figure 4 As shown, when the unmanned boat 700 is released, the closing frame 120 rotates to open the frame body 110, the storage device places the unmanned boat on the retracting seat, the closing frame 120 closes the frame body 110, and the retracting drive device 230 drives the boom 220 to rotate outward to move the frame structure 100 outside the deck. At the same time, the hydraulic winch 300 relaxes the sling 310, and the frame structure 100 moves downward to the water surface. The closing frame 120 rotates to open the frame body 110, completing the release of the unmanned boat, and then the boom 220 and the hydraulic winch 300 lift the frame structure 100 back to the initial position of the deck.

[0040] When recovering the unmanned boat 700, the retractable drive device 230 drives the boom 220 to rotate outward, moving the frame structure 100 outside the deck, and at the same time the hydraulic winch 300 loosens the sling 310, the frame structure 100 moves downward to the water surface, the closing frame 120 rotates to open the frame body 110, and after the hull enters the frame structure 100, the frame body 110 is closed, the hydraulic winch 300 tightens the sling 310, the boom 220 rotates to lift the frame structure 100 back to the initial position, the closing frame 120 rotates to open the frame body 110, and the storage device 600 moves the unmanned boat 700 out of the opening of the frame body 110.

[0041] The storage device 600 transports the unmanned boat in the frame structure to a centralized storage location, or directly stores it on the storage device. The unmanned boat can also be directly stored in the frame body.

[0042] The control system 400 receives instructions from the operator or instructions in the preset program, and parses these instructions to determine the specific retraction and release actions and sequence of the unmanned boat. By accurately adjusting the working status of the hydraulic winch, motor or other driving device, the control system can ensure the smooth rotation of the boom, the precise lifting and lowering of the frame structure, and the gentle placement and recovery of the unmanned boat to avoid damage caused by improper operation. Real-time monitoring of various parameters during the retraction and release process, such as hydraulic pressure, motor load, position feedback, etc., to ensure that all operations are carried out within a safe range, and abnormal situations can be discovered and handled in a timely manner. Provide a friendly human-computer interaction interface so that operators can intuitively understand the system status, issue instructions and monitor the entire operation process, improving the convenience and accuracy of operation.

[0043] The power source 500 provides the necessary energy for the entire retractable structure to drive each moving part to perform the required action, converts the original energy (such as electricity, fuel, etc.) into hydraulic energy, and provides power for actuators such as hydraulic winches through components such as hydraulic pumps and hydraulic motors.
