Description

Technical Field

[0001] This utility model relates to the field of ship technology, specifically an unmanned multi-functional ship with emergency avoidance function. Background Technology

[0002] Against the backdrop of the global intelligent transformation of shipping, unmanned multi-purpose vessels have become core equipment in the industry due to their efficiency and flexibility in areas such as marine resource development, environmental monitoring, and emergency rescue. The development of their emergency avoidance functions must simultaneously meet regulatory compliance, environmental adaptability to complex sea conditions, and the needs of multi-task collaboration. Current technology has achieved deep integration of multi-sensor fusion perception and intelligent collision avoidance algorithms. For example, Euroship's L4-level unmanned cruise ship achieves dynamic obstacle avoidance through a centimeter-level combined positioning system and multiple emergency response mechanisms.

[0003] In shallow wetlands, inland river reed beds, and other waters with dense aquatic plants, when the propeller at the stern of an unmanned multi-functional boat rotates at high speed, the water flow will roll the surrounding aquatic plants into the propeller blade area. Initially, a small amount of aquatic plants will become entangled in the propeller shaft, but as the sailing time increases, they will gradually accumulate and form a dense clump of plants, causing a sudden increase in the rotational resistance of the propeller blades. This will lead to a power interruption and cause the boat to lose its steering and braking capabilities. To address this, we propose an unmanned multi-functional boat with emergency avoidance capabilities. Utility Model Content

[0004] The purpose of this invention is to provide an unmanned multi-functional vessel with emergency avoidance capabilities to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An unmanned multi-functional vessel with emergency avoidance function includes a hull, a steering mechanism fixedly connected to the stern of the hull, a propeller fixedly connected to the end of the steering mechanism opposite to the hull, a motor built into the end of the propeller opposite to the hull, a propeller fixedly connected to the output end of the motor, a cleaning component for cleaning seaweed externally provided on the propeller, and an auxiliary avoidance component provided on the hull.

[0007] Preferably, the cleaning assembly includes two sets of threaded rods symmetrically fixedly connected to the front and rear end surfaces of the propeller. Each set of threaded rods has a fixed seat slidably connected laterally. Each set of threaded rods is fitted with a washer. Each set of threaded rods is threaded with a self-locking nut sleeve. The end of each set of self-locking nut sleeves facing away from the first grid plate is fixedly connected to a first grid plate. The end of the first grid plate facing away from the propeller is fixedly connected to a housing. The end of the housing facing away from the propeller is fixedly connected to a second grid plate. A connecting rod is fixedly connected to the right end of the propeller, and the connecting rod is rotatably connected to the second grid plate. Multiple sets of first cleaning scrapers are fixedly connected at equal intervals to the outer wall of the connecting rod. Each set of first cleaning scrapers facing the propeller has a blade fixedly connected to it. The blades are all in contact with the outer wall of the housing. The end of each set of first cleaning scrapers facing away from the propeller is fixedly connected to a second cleaning scraper.

[0008] Preferably, the first cleaning scraper is provided in six sets at equal intervals, and each of the six sets of the first cleaning scraper has two sets of second cleaning scrapers symmetrically arranged on the surface of the end of the first cleaning scraper away from the pusher, and the second cleaning scraper is designed with a double-edged blade.

[0009] Preferably, the surface of the self-locking nut sleeve is provided with several sets of grooves, and the several sets of grooves are used to prevent the self-locking nut sleeve from slipping.

[0010] Preferably, the avoidance component includes an emergency avoidance control module fixedly connected to the top of the hull, a high-definition camera built into the left end surface of the hull, two sets of ultrasonic sensors symmetrically built into the front and rear end surfaces of the hull, and two sets of telescopic braking fins symmetrically fixedly connected to the side walls of the hull below the two sets of ultrasonic sensors.

[0011] Preferably, the high-definition camera, ultrasonic sensor, and telescopic brake fin are electrically connected to the emergency avoidance control module, which is electrically connected to the steering mechanism and the thruster.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model provides a protective cover consisting of a first grid plate, an outer shell, and a second grid plate on the outside of the propeller. This prevents seaweed or aquatic plants from getting tangled on the propeller, which could lead to propeller power failure. The propeller rotation synchronously drives the first cleaning scraper to rotate, which in turn drives the second cleaning scraper to rotate and cut the seaweed or aquatic plants. At the same time, the first cleaning scraper and the blades scrape off the attached materials on the surface of the outer shell and the second grid plate, thus providing a safe environment for the propeller during use. This effectively solves the problem that as sailing time increases, dense clumps of grass gradually accumulate, causing a sudden increase in propeller rotation resistance, which in turn leads to power interruption and loss of steering and braking ability of the hull.

[0014] 2. This utility model uses a high-definition camera on the port side of the hull to capture obstacles in front and identify their types in real time. Two sets of ultrasonic sensors at the front and rear ends simultaneously detect the distance to obstacles. The data is transmitted in real time to the top emergency avoidance control module. After the module analyzes and judges the level of danger, if an avoidance command is triggered, it immediately controls the corresponding telescopic brake fin to extend rapidly. By increasing water resistance, it achieves deceleration or lateral attitude adjustment, thereby avoiding the risk of collision and improving the emergency avoidance capability of the hull.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4As shown, an unmanned multi-functional vessel with emergency avoidance function includes a hull 1, a steering mechanism 2 fixedly connected to the stern of the hull 1, a thruster 3 fixedly connected to the end of the steering mechanism 2 opposite to the hull 1, a motor 4 built into the end of the thruster 3 opposite to the hull 1, a propeller 5 fixedly connected to the output end of the motor 4, a cleaning component 6 for cleaning seaweed is provided on the outside of the propeller 5, and an auxiliary avoidance component 7 is provided on the hull 1.

[0023] As a technical optimization of this utility model, the cleaning component 6 includes two sets of threaded rods 61 symmetrically fixedly connected to the front and rear end surfaces of the pusher 3. Each set of threaded rods 61 is laterally slidably connected to a fixing seat 62. Each set of threaded rods 61 is fitted with a washer 63. Each set of threaded rods 61 is threadedly connected to a self-locking nut sleeve 64. The end of each set of self-locking nut sleeves 64 facing away from the first grid plate 65 is fixedly connected to the first grid plate 65. The end of the first grid plate 65 facing away from the pusher 3 is fixedly connected to a housing 66. A second grid plate 67 is fixedly connected to the end of the outer shell 66 away from the thruster 3. A connecting rod 68 is fixedly connected to the right end of the propeller 5, and the connecting rod 68 is rotatably connected to the second grid plate 67. Multiple sets of first cleaning scrapers 69 are fixedly connected at equal intervals on the outer wall of the connecting rod 68. Blades 610 are fixedly connected to the end of the multiple sets of first cleaning scrapers 69 facing the thruster 3. The multiple sets of blades 610 are all in contact with the outer wall of the outer shell 66. A second cleaning scraper 611 is fixedly connected to the end of the multiple sets of first cleaning scrapers 69 away from the thruster 3.

[0024] In specific implementation, a protective cover consisting of a first grid plate 65, a shell 66, and a second grid plate 67 is provided outside the propeller 5 to prevent seaweed or aquatic plants from getting tangled on the propeller 5, which could lead to power failure. The rotation of the propeller 5 synchronously drives the first cleaning scraper 69 to rotate, which in turn drives the second cleaning scraper 611 to rotate and cut the seaweed or aquatic plants. At the same time, the first cleaning scraper 69 and the blade 610 scrape off the attached materials on the surface of the shell 66 and the second grid plate 67, thus providing a safe environment for the propeller 5 during use. This effectively solves the problem that as the sailing time increases, dense grass clumps gradually accumulate, causing a sudden increase in the rotational resistance of the propeller blades, which in turn causes a power interruption and makes the hull 1 lose its steering and braking capabilities.

[0025] As a technical optimization of this utility model, six sets of first cleaning scrapers 69 are equally spaced. Two sets of second cleaning scrapers 611 are symmetrically arranged on the surface of the six sets of first cleaning scrapers 69 away from the pusher 3. The second cleaning scrapers 611 are all double-edged.

[0026] In practice, the propeller 5 can synchronously drive the first cleaning scraper 69 to rotate when it rotates in both directions. Then, the first cleaning scraper 69 drives the second cleaning scraper 611 to rotate in both directions, thereby cutting the weeds in both directions and preventing the weeds from becoming too tightly entangled, which would lead to a decrease in the unidirectional cutting effect.

[0027] As a technical optimization of this utility model, the surface of the self-locking nut sleeve 64 is provided with several sets of grooves, and the several sets of grooves are used to prevent the self-locking nut sleeve 64 from slipping.

[0028] In practice, this design facilitates the rotation of the self-locking nut sleeve 64 by staff, preventing slippage during rotation and thus avoiding difficulties in disassembling the first grid plate 65.

[0029] As a technical optimization of this utility model, the emergency avoidance component 7 includes an emergency avoidance control module 71 fixedly connected to the top of the hull 1. A high-definition camera 72 is built into the left end surface of the hull 1. Two sets of ultrasonic sensors 73 are symmetrically built into the front and rear end surfaces of the hull 1. Two sets of telescopic brake fins 74 are symmetrically fixedly connected to the side wall of the hull 1 below the two sets of ultrasonic sensors 73. The high-definition camera 72, ultrasonic sensors 73 and telescopic brake fins 74 are electrically connected to the emergency avoidance control module 71. The emergency avoidance control module 71 is electrically connected to the steering mechanism 2 and the propeller 3.

[0030] In practice, a high-definition camera 72 on the port side of the hull 1 captures and identifies obstacles in front of it in real time, and two sets of ultrasonic sensors 73 at the front and rear ends detect the distance to the obstacles simultaneously. The data is transmitted to the top emergency avoidance control module 71 in real time. After the module analyzes and judges the level of danger, if an avoidance command is triggered, it immediately controls the corresponding side telescopic brake fin 74 to extend quickly. By increasing water resistance, it achieves deceleration or lateral attitude adjustment, thereby avoiding the risk of collision and improving the emergency avoidance capability of the hull 1.

[0031] In use, this utility model uses the first grid plate 65 to drive the fixed seat 62 to slide and connect with the threaded rod 61, and then uses the self-locking nut sleeve 64 to thread and connect with the threaded rod 61. The self-locking nut sleeve 64 pushes the washer 63 to slide on the threaded rod 61, and the washer 63 continuously squeezes against the fixed seat 62, thereby fixing the outer shell 66 and the first grid plate 65 to the propeller 3. Then, the propeller 5 rotates synchronously to drive the connecting rod 68 to rotate, so that the first cleaning scraper 69 and the blade 610 rotate and remove weeds or attachments on the outer shell 66 and the second grid plate 67. Then, the second cleaning scraper 611 rotates coaxially to cut the weeds, thereby achieving the purpose of cleaning the weeds outside the propeller 5 and preventing the propeller 5 from being entangled with too many weeds, which could lead to the propeller 5 losing power.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
