Description

Technical Field

[0001] The present invention relates to the technical field of unmanned ships, and in particular to an obstacle avoidance alarm device for an unmanned ship and a use method thereof. Background Art

[0002] Unmanned boat technology has developed rapidly in recent years and is widely used in water monitoring, environmental monitoring, cargo transportation and other fields. In these application scenarios, obstacle avoidance alarm devices are one of the key technologies to ensure the safe operation of unmanned boats. China's authorized invention patent (Announcement No.: CN219619339U) discloses a smart river chief automatic river patrol equipment. Its obstacle avoidance system mostly uses ultrasonic sensors for obstacle detection and combines sound and light alarms for warnings. Although the existing technology can achieve the obstacle avoidance function to a certain extent, there are still some defects and deficiencies that need to be improved;

[0003] When the obstacle avoidance alarm device for unmanned ships in the prior art is used, the sonic obstacle avoidance device is installed at the bow. In the marine environment, the unmanned ship will face the attachment of a large number of marine organisms, such as algae and shellfish, when sailing for a long time. These organisms attach to the ultrasonic obstacle avoidance device, which not only increases the weight of the device, but also may block the emission and reception of ultrasonic waves, resulting in a decrease in measurement accuracy. Therefore, an obstacle avoidance alarm device for unmanned ships and a method of using the same are proposed to overcome the above-mentioned defects. Summary of the invention

[0004] The purpose of the present invention is to provide an obstacle avoidance alarm device for an unmanned ship and a method of using the same, which protects an ultrasonic obstacle avoidance sensor by a metal mesh and a guide plate, thereby preventing the ultrasonic obstacle avoidance sensor from being physically damaged by wear or impact.

[0005] The present invention is achieved through the following technical solutions:

[0006] The present invention discloses an obstacle avoidance alarm device for unmanned boats, comprising an unmanned boat body, a mounting groove is provided on the unmanned boat body, a mounting seat is installed in the mounting groove, an audible and visual alarm is installed on the unmanned boat body, and an ultrasonic obstacle avoidance sensor is installed on the mounting seat.

[0007] A metal mesh is installed on the mounting seat, a vertical plate is installed on the metal mesh, a vertical slot matching the vertical plate is opened on the mounting seat, a through slot is opened in the mounting seat, the through slot is connected to the vertical slot and is located on one side of the vertical slot, and a limiting mechanism is installed in the through slot.

[0008] The limiting mechanism has a rotating shaft, which is installed in the through slot. A guide plate is installed on the rotating shaft. A buckle is installed on the top of the guide plate. A buckle matching the buckle is opened on the vertical plate. A spring piece is installed on the inner wall of the through slot, and the spring piece touches the bottom of the guide plate.

[0009] A U-shaped frame is installed on the outer surface of the mounting seat, and an anti-mistaken touch mechanism is installed on the U-shaped frame.

[0010] The anti-mistouch mechanism has a pressure plate, a limiting ring is installed on the outer surface of the pressure plate, a block is installed on the pressure plate, a moving block is installed on the outer surface of the block, a clearance opening and a moving groove are opened in the U-shaped frame, the moving groove is connected to the clearance opening, the block is located in the clearance opening, the moving block is fitted in the moving groove, and a first spring is connected between the block and the inner wall of the moving groove.

[0011] Preferably, the mounting seat is provided with two threaded holes.

[0012] Preferably, a holder is installed on the metal mesh, and a screw is installed on the holder. The number of the screws is two, and the two screws are respectively threadedly engaged in the corresponding threaded holes.

[0013] Preferably, the guide plate is provided with anti-skid grooves, and the outer surface of the vertical plate is in contact with the anti-skid grooves.

[0014] Preferably, a reserved hole is opened inside the mounting seat, and two arc-shaped pieces are installed in the reserved hole.

[0015] Preferably, a fixing groove is provided in the mounting seat, the number of the fixing grooves is two, and a cylinder is installed in each of the two fixing grooves.

[0016] Preferably, second springs are installed inside the two cylinders, and the two second springs are respectively connected to the corresponding arc-shaped sheets.

[0017] Preferably, a limiting groove and a sliding groove are provided at the bottom of the mounting seat, and the limiting groove is connected to the sliding groove.

[0018] Preferably, the pressure plate is slidably fitted in the slide groove, the limiting ring is slidably fitted in the limiting groove, the outer surface of the pressure plate contacts the bottom of the guide plate, and the positions of the pressure plate and the clearance opening correspond to each other.

[0019] Install the mounting base on the unmanned boat body, and then install the sound and light alarm and ultrasonic obstacle avoidance sensor. At this time, the cable of the ultrasonic obstacle avoidance sensor passes through the reserved hole into the unmanned boat body for electrical connection, and then the rebound of the second spring pushes the two arc-shaped pieces to move toward the center. At this time, the two arc-shaped pieces will tighten and fix the cable.

[0020] When installing the metal mesh, fix the holder in the threaded hole through a screw to install one end of the metal mesh. Then insert the vertical plate vertically into the vertical groove, push the bottom of the guide plate to move through the spring sheet, so that the guide plate rotates along the shaft and the buckle is inserted into the bayonet to fix the vertical plate, thereby completing the installation of the metal mesh and providing protection for the ultrasonic obstacle avoidance sensor.

[0021] When the metal mesh needs to be cleaned or replaced, the stopper is pushed to one side. At this time, the moving block moves in the moving groove to limit the movement of the stopper. The stopper compresses the first spring and moves out of the clearance opening. Then the pressure plate is pressed from the clearance opening and the movement of the pressure plate is limited by the limiting ring. After pressing, one end of the pressure plate contacts and pushes the bottom of the guide plate to move, so that the spring sheet is deformed and the buckle at the top of the guide plate moves out of the buckle opening. After disassembly is completed, the stopper is released so that the first spring pushes the stopper to move into the clearance opening and continues to contact the clearance opening.

[0022] A method for using an obstacle avoidance alarm device for an unmanned ship comprises the following steps:

[0023] When the unmanned boat is driving automatically or the operator manually controls the boat through a remote control, the sound and light alarm is used to remind passing ships and animals. In conjunction with the ultrasonic obstacle avoidance sensor, the ultrasonic wave is emitted and then reflected back to the ultrasonic obstacle avoidance sensor for receiving and reminding, ensuring the normal driving of the boat. If a collision occurs with an object, the spring plate pushes the guide plate to snap the buckle into the slot to fix the vertical plate, and then the ultrasonic obstacle avoidance sensor is protected by a metal mesh to block the object.

[0024] The present invention has the following beneficial effects:

[0025] 1. Under the cooperation of the metal mesh and the guide plate, the spring sheet pushes the guide plate to insert the buckle into the bayonet to fix the vertical plate, thereby completing the installation of the metal mesh. At this time, the metal mesh provides protection for the ultrasonic obstacle avoidance sensor, effectively preventing the attachment of marine organisms, seawater corrosion and impurity interference, and provides a solid physical barrier for the ultrasonic obstacle avoidance device, thereby extending the service life of the device and improving its stability and reliability in complex marine environments. When the metal mesh needs to be cleaned or replaced, the vertical plate can be released by pressing the pressure plate to rotate the guide plate along the shaft to remove the buckle from the bayonet. The operator can quickly complete the disassembly and assembly operations, thereby greatly reducing the maintenance cost and time cost, and improving the continuous operation capability of the unmanned ship;

[0026] 2. Under the cooperation of the U-shaped frame and the anti-mistouch mechanism, the stopper is released so that the first spring pushes the stopper to move into the clearance opening and continues to resist the clearance opening, thereby preventing the operator or the unmanned boat body from accidentally touching the pressure plate during driving, causing the metal mesh to be disassembled, thereby ensuring the continuous operation of the ultrasonic obstacle avoidance sensor and the safety of the unmanned boat body, ensuring the accuracy and reliability of the metal mesh replacement operation, and thus increasing the protection performance of the ultrasonic obstacle avoidance sensor;

[0027] 3. With the cooperation of the arc-shaped piece and the second spring, when installing the ultrasonic obstacle avoidance sensor, the cable passes through the reserved hole and is electrically connected to the unmanned boat body. At this time, the arc-shaped piece is pushed to move by the second spring. The two arc-shaped pieces can be used to gather the cables, effectively organize and simplify the cable layout, make the cable management more orderly, reduce the disorder of cables, thereby improving the overall cable management efficiency, and reducing the risk of tripping and damage to wires and cables, providing a safer working environment. The neat arrangement of cables also helps to avoid accidental pulling or damage caused by cable clutter, and reduce the risk of electrical fires. BRIEF DESCRIPTION OF THE DRAWINGS

When installing the metal mesh 5, one end of the metal mesh 5 is installed by fixing the clamping base 501 in the threaded hole 303 through the screw 502, and then the other end of the metal mesh 5 is installed through a limiting mechanism.

The outer surface of the pressure plate 12 touches the bottom of the guide plate 8, and the positions of the pressure plate 12 and the yielding opening 1401 correspond to each other. When the pressure plate 12 contacts the guide plate 8, the pressure plate 12 slides from the sliding groove 305, and the limiting ring 11 slides from the limiting groove 304 to limit the movement of the pressure plate 12. An anti-mistaken touch mechanism is installed on the U-shaped frame 14.

[0041] A reserved hole 20 is provided inside the mounting base 3. When the ultrasonic obstacle avoidance sensor 4 is installed, the cable passes through the reserved hole 20.

There are two fixed grooves, and cylinders 17 are installed in both fixed grooves. Second springs 18 are installed inside the two cylinders 17. The two second springs 18 are respectively connected to the corresponding arc-shaped pieces 19. The rebound of the second springs 18 pushes the two arc-shaped pieces 19 to move toward the center.

[0042] Install the mounting base 3 on the unmanned boat body 1, and then install the sound and light alarm 2 and the ultrasonic obstacle avoidance sensor 4. At this time, the cable of the ultrasonic obstacle avoidance sensor 4 passes through the reserved hole 20 to the unmanned boat body 1 for electrical connection, and then the two arc-shaped pieces 19 are pushed toward the center by the rebound of the second spring 18. At this time, the two arc-shaped pieces 19 gather and fix the cables, effectively organizing and simplifying the cable layout, making the cable management more orderly, reducing the disorder of cables, thereby improving the overall cable management efficiency, and reducing the risk of tripping and damage to wires and cables, providing a safer working environment.

[0043] When installing the metal mesh 5, the holder 501 is fixed in the threaded hole 303 by the screw 502 to install one end of the metal mesh 5.

[0045] A method for using an obstacle avoidance alarm device for an unmanned ship comprises the following steps:

[0046] When the unmanned boat body 1 is driving automatically or the operator manually controls the boat body through a remote control, the sound and light alarm 2 is used to remind passing ships and animals, and the ultrasonic obstacle avoidance sensor 4 is used to emit ultrasonic waves that touch an object and then reflect the ultrasonic waves back to the ultrasonic obstacle avoidance sensor 4 for receiving and reminding, thereby ensuring the normal driving of the boat body. If a collision occurs with an object, the spring sheet 10 pushes the guide plate 8 to insert the buckle 9 into the bayonet 601 to fix the vertical plate 6, and then the ultrasonic obstacle avoidance sensor 4 is protected by the metal mesh 5 to block the object.
