Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a ship obstacle avoidance device. Background Art

[0002] When a ship is sailing, an ultrasonic obstacle avoidance sensor is used to detect an obstacle and transmit it to an ultrasonic obstacle avoidance module. A compass and a GPS positioning system accurately locate the position of the obstacle, facilitating subsequent data collection and enabling the ship to avoid in a timely manner. In the patent authorization announcement number: CN219687552U, the authorization announcement date: September 15, 2023, and the name is a ship obstacle avoidance device. To prevent the ultrasonic sensor from malfunctioning for maintenance, by rotating a handwheel to rotate a threaded rod, while the threaded rod rotates, it will drive a first connecting piece to move along the axis of the threaded rod. The first connecting piece drives the protective housing to move upward, and then the staff repairs or replaces the ultrasonic sensor inside the protective housing. Since there are seaweeds and floating plastic bags in the water during navigation, the plastic bags and seaweeds will wind around the threaded rod, resulting in the inability to rotate the threaded rod for height adjustment and maintain the ultrasonic sensor.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Embodiment 1: Refer to Figures 1-3, A ship obstacle avoidance device, including a fixing frame 1, and mounting holes are provided on the fixing frame 1 so that the fixing frame 1 can be fixed on the ship through bolts.

[0020] A threaded rod 10 is rotatably connected to the fixing frame 1 through a bearing. A threaded sleeve 11 is threadedly penetrated through the threaded rod 10. A housing 2 is fixedly connected to the threaded sleeve 11. An ultrasonic sensor is provided inside the housing 2. The ultrasonic sensor is signal-connected to the obstacle avoidance module on the ship. The housing 2 is limited by a limiting mechanism. A connecting plate 6 is fixedly connected to the fixing frame 1. The connecting plate 6 is connected to a cutting knife 4 through a connecting mechanism. The cutting knife 4 moves through a moving mechanism. The cutting knife 4 can abut against the threaded rod 10. When a plastic bag or seaweed is wound around the threaded rod 10 and causes the threaded rod 10 to be unable to rotate, it moves through the moving mechanism, which will drive the cutting knife 4 to move and cut off the wound plastic bag or seaweed to prevent it from winding around the threaded rod 10, so as to rotate the threaded rod 10, raise the housing 2, disassemble it, and maintain the internal ultrasonic sensor.

[0021] The limiting mechanism includes a limiting rod 3. The limiting rod 3 is fixedly connected to the fixing frame 1. A moving sleeve 16 is penetrated through the limiting rod 3. The moving sleeve 16 is fixedly connected to the housing 2. By using the limiting rod 3 and the moving sleeve 16, the housing 2 is limited to prevent the housing 2 from rotating.

[0022] The connecting mechanism includes a connecting sleeve 7. The connecting sleeve 7 is fixedly connected to the connecting plate 6. A connecting edge 5 is fixedly connected to the cutting knife 4. The connecting edge 5 can be inserted into the connecting sleeve 7. By using the connecting edge 5 and the connecting sleeve 7 for connection, the cutting knife 4 is limited longitudinally to prevent the cutting knife 4 from moving longitudinally.

[0023] The moving mechanism includes a telescopic rod 8. The telescopic rod 8 is fixedly connected to the fixing frame 1. An articulated rod 9 is hinged to the telescopic rod 8. The articulated rod 9 is hinged to the cutting knife 4. The telescopic rod 8 is a hydraulic telescopic rod. By extending the telescopic rod 8, the inclination angle of the articulated rod 9 is adjusted, thereby pushing the cutting knife 4 to move and abutting the cutting knife 4 against the threaded rod 10 and the limiting rod 3 to cut off the winding object.

[0024] Embodiment 2: Refer to Figures 1-4 , As another preferred embodiment of the present invention, on the basis of Embodiment 1, a rotating part 14 is fixedly connected to the threaded rod 10. A fixing rod 15 is penetrated through the rotating part 14. A fixing sleeve 13 is fixedly connected to the fixing frame 1. The fixing rod 15 can extend into the fixing sleeve 13. By connecting the fixing rod 15 and the fixing sleeve 13, the threaded rod 10 is limited to prevent the threaded rod 10 from rotating when the ship is moving, thereby ensuring the fixed position of the housing 2.

[0025] When in use: extend the telescopic rod 8 to adjust the inclination angle of the articulated rod 9, thereby pushing the cutter 4 to move until the cutter 4 abuts against the limiting rod 3 of the threaded rod 10 to cut off the winding. Then rotate the threaded rod 10 to raise the housing 2 and disassemble it to maintain the ultrasonic sensor inside.

[0026] Embodiment 3: Refer to Figure 4 , as another preferred embodiment of the present invention, on the basis of Embodiment 2, a connecting rope 12 is connected to the fixing rod 15. The connecting rope 12 is connected to the fixing bracket 1. By using the connecting rope 12, the fixing rod 15 is fixed to prevent the fixing rod 15 from being lost.

[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
