Description

Technical Field

[0001] This utility model belongs to the technical field of cruise ships, specifically relating to an unmanned cruise ship. Background Technology

[0002] Unmanned cruise ships are a type of water transportation that integrates advanced technology to achieve autonomous navigation. They are typically equipped with GPS, lidar, millimeter-wave radar, and various sensors, enabling them to perceive the surrounding environment in real time, automatically optimize their routes, and autonomously complete a series of operations such as navigation, obstacle avoidance, and mooring, significantly reducing the risks associated with human operation.

[0003] The existing utility model patent with publication number CN220298730U discloses a power unit for an unmanned surface vessel (USV). It states that "by installing a protective sleeve over the propeller, the blades can be fully protected, preventing them from being exposed and entangled by foreign objects or weeds, thus avoiding failure. It also prevents damage from grounding or collisions. Furthermore, the power unit employs a belt-driven dual-propeller design with a transmission ratio of less than 1, ensuring high-speed propeller drive and high power, thereby achieving high-power, high-safety operation for the USV." While this addresses the shortcomings of existing unmanned surface vessel (USV) power systems, it does not guarantee a safe and efficient unmanned surface vessel operation. The power units of boats generally adopt a single propeller drive design and are exposed and fixed, which makes them susceptible to entanglement by foreign objects or aquatic plants, leading to failure. They are also prone to damage due to grounding or collisions with foreign objects, making it difficult to guarantee the power safety of unmanned boats. However, the anti-collision structures currently used are usually protruding and fixed to the edge of the hull, such as anti-collision plates and anti-collision pulleys. This makes it difficult to adjust them according to the water environment. In narrow areas, the structure is too outward, which obstructs passage. It is impossible to adjust the extension range of the anti-collision structure according to the distance of obstacles. Therefore, an unmanned cruise boat has been proposed. Utility Model Content

[0004] The purpose of this invention is to provide an unmanned cruise ship to solve the technical problem of not being able to adjust the extension range of the anti-collision structure according to the distance to obstacles.

[0005] To solve the above-mentioned technical problems, this utility model provides an unmanned cruise ship, including a cruise ship body, with a device box fixedly connected to both sides of the top of the cruise ship body, and a pair of side holes opened on one side wall of the device box.

[0006] The inner cavity of the side hole is equipped with an anti-collision pulley. A motor is installed in the middle of the inner wall of the cruise ship body. A threaded rod is driven through the output shaft of the motor. A telescopic plate is threaded through the threaded rod. A buffer and a removable part are provided between the anti-collision pulley and the telescopic plate.

[0007] Furthermore, one end of the threaded rod is rotatably connected to the inner wall of the device box, the telescopic plate is slidably connected to the inner wall of the device box, and movable holes are provided on both sides of the top of the device box.

[0008] Furthermore, the buffer component includes a buffer box and a connecting rod, the buffer box being placed between the anti-collision pulley and the telescopic plate, and the connecting rod being fixed to the back of the anti-collision pulley.

[0009] Furthermore, one end of the connecting rod slides through the surface of the buffer box to its inner cavity and is fixedly connected to a movable disk, with a spring connecting the movable disk to the inner wall of the buffer box.

[0010] Furthermore, the detachable component includes a U-shaped plate fixed to the top of the telescopic plate, the U-shaped plate being placed in the inner cavity of the same-side movable hole, and a through hole being provided on both sides of the U-shaped plate.

[0011] Furthermore, a fixing block is slidably connected to the inner side of the U-shaped plate, and a second through hole is provided on one side wall of the fixing block. The bottom end of the fixing block is fixedly connected to the top end of the buffer box on the same side, and a positioning plate is movably inserted into the inner cavity of the first and second through holes on the same side.

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

[0013] 1. This utility model uses a motor to drive a threaded rod to rotate, causing a telescopic plate to slide along an anti-collision pulley. This allows the anti-collision pulley to extend and retract at the side hole of the device box, thus adjusting the extension range of the anti-collision structure according to the distance to obstacles, effectively improving the passage capacity in narrow waterways. The spring in the buffer component works in conjunction with the moving disc to absorb the impact force during a collision, enhancing the buffering effect. The easy-to-disassemble component uses a positioning plate inserted through holes one and two to conveniently fix the anti-collision pulley, buffer component, and telescopic plate. When a component is damaged, the positioning plate can be quickly disassembled for replacement, reducing maintenance difficulty and time costs, and balancing flexibility, safety, and ease of maintenance.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example:

[0024] like Figures 1 to 4 As shown, an unmanned cruise ship includes a cruise ship body 1, which serves as the main structure of the unmanned cruise ship, carrying all the equipment, systems, passengers or cargo of the cruise ship, and is the basic platform for realizing the functions of the entire cruise ship. Both sides of the top of the cruise ship body 1 are fixedly connected to device boxes 2, providing installation space for components such as anti-collision pulleys 4. A pair of side holes 3 are opened on one side wall of the device box 2, providing a channel for the extension and retraction of the anti-collision pulleys 4, so that the anti-collision pulleys 4 can freely enter and exit the device box 2, thereby realizing the function of adjusting the extension range of the anti-collision structure according to actual needs.

[0025] The inner cavity of the side hole 3 is equipped with an anti-collision pulley 4, which directly contacts external obstacles. By rolling itself, it converts the sliding friction during the collision into rolling friction, greatly reducing the impact force of the collision. At the same time, its telescopic design can retract in narrow waters to avoid obstructing the passage of the cruise ship, and extend in open or dangerous waters to enhance the protective capability. A motor 5 is installed in the middle of the inner wall of the cruise ship body 1 as a power source. The output shaft rotates to provide power to the threaded rod 6, driving the telescopic movement of the entire anti-collision structure. The extension or retraction state of the anti-collision pulley 4 can be adjusted. The output shaft of the motor 5 is connected to the threaded rod 6, and the threaded rod 6 is threaded to the telescopic plate 7. A buffer 8 and a removable part 9 are provided between the anti-collision pulley 4 and the telescopic plate 7.

[0026] Preferably, one end of the threaded rod 6 is rotatably connected to the inner wall of the device box 2, the telescopic plate 7 is slidably connected to the inner wall of the device box 2, and movable holes 10 are provided on both sides of the top of the device box 2.

[0027] Preferably, the buffer component 8 includes a buffer box 81 and a connecting rod 82. The buffer box 81 is placed between the anti-collision pulley 4 and the telescopic plate 7 to provide installation space for the internal buffer components. The connecting rod 82 is fixed to the back of the anti-collision pulley 4 to transfer the collision force received by the anti-collision pulley 4 to the moving plate 83, which drives the moving plate 83 to move inside the buffer box 81. One end of the connecting rod 82 slides through the surface of the buffer box 81 to its inner cavity and is fixedly connected to the moving plate 83. A spring 84 is connected between the moving plate 83 and the inner wall of the buffer box 81 to absorb the collision energy and reduce the impact of the collision on the cruise ship.

[0028] Preferably, the easy-to-disassemble component 9 includes a U-shaped plate 91 fixed to the top of the telescopic plate 7. The U-shaped plate 91 is placed in the inner cavity of the same-side movable hole 10. Both sides of the U-shaped plate 91 are provided with a first through hole 92. A fixing block 93 is slidably connected to the inner side of the U-shaped plate 91. A second through hole 94 is provided on one side wall of the fixing block 93. The bottom end of the fixing block 93 is fixedly connected to the top end of the same-side buffer box 81. A positioning plate 95 is movably inserted into the inner cavity of the first through hole 92 and the second through hole 94 on the same side, so as to realize the quick connection and fixation of the U-shaped plate 91 and the fixing block 93, thereby firmly connecting the anti-collision pulley 4, the buffer component 8 and the telescopic plate 7.

[0029] In summary, during operation, motor 5 starts, and the output shaft drives the threaded rod 6 to rotate. Based on the principle of threaded transmission, the telescopic plate 7, which is threadedly connected to the threaded rod 6, slides along the inner wall of the device box 2, pushing the anti-collision pulley 4 to extend outward or retract inward along the side hole 3 of the device box 2. This dynamically adjusts the extension range of the anti-collision structure according to the distance to the obstacle. When the cruise ship comes into contact with the obstacle, the anti-collision pulley 4 reduces friction by rolling. At the same time, the collision force is transmitted to the moving disc 83 in the buffer box 81 through the connecting rod 82, and the compression spring 84 converts the kinetic energy into elastic potential energy, thereby achieving buffering and shock absorption. In daily maintenance, if it is necessary to replace the anti-collision pulley 4 or the buffer component 8, simply pull out the positioning plate 95 inserted in the through hole 92 of the U-shaped plate 91 and the through hole 94 of the fixing block 93 to remove the damaged parts and complete the quick repair and replacement.
