Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a traffic warning display device for inland waterways. Background Technology

[0002] Inland waterways, as vital waterway transportation channels, experience complex traffic conditions and frequently require real-time dissemination of various warnings and guidance information to navigating vessels, including traffic control, water level and weather updates, channel congestion, and temporary navigation closures. Traffic warning display devices are the core equipment for achieving this function. They are typically fixedly installed on both sides of the waterway, bridges, locks, and other key locations, presenting visual information to vessel operators through their displays. They are crucial infrastructure for ensuring efficient waterway traffic and preventing traffic accidents.

[0003] However, it is worth considering that most existing devices are fixed installations, and the orientation of the display screen is determined during installation. This means that they can only provide a good warning effect to ships coming from a specific direction. For ships coming from other directions, the warning effect is greatly reduced due to poor visibility or inability to see the screen at all.

[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a traffic warning display device for inland waterways, so as to solve the problem that the warning effect is greatly reduced due to poor viewing angle or inability to see at all.

[0006] Based on the above objectives, this utility model provides a traffic warning display device for inland waterways, including a display body and a mounting shell disposed below the display body. A rotating frame is fixedly connected to the bottom end of the display body, a support base is provided inside the mounting shell, and an avoidance hole that cooperates with the support base is opened on the top of the inner wall of the mounting shell. A first rotating shaft is rotatably connected to the support base. The top end of the first rotating shaft is fixedly connected to the bottom of the rotating frame. A sliding drive assembly that cooperates with the first rotating shaft is installed on the mounting shell. Several rollers are fixedly connected to the bottom of the rotating frame, and the bottom ends of the rollers are in contact with the top of the mounting shell. A positioning structure that is adapted to the support base is installed on the mounting shell.

[0007] Preferably, the positioning structure includes two guide posts fixedly installed in the mounting housing, and the guide posts penetrate the support base. Pressing plates are provided on both sides of the support base, and inclined surfaces that cooperate with the pressing plates are provided at both ends of the support base. A stopper that cooperates with the pressing plates is installed on the mounting housing.

[0008] Preferably, the stopper includes an iron ring that is slidably sleeved on the outside of the pressing plate. The iron ring is fixedly connected to the outer wall of the mounting shell. An insert plate passes through the iron ring, and the pressing plate has an insertion hole that matches the insert plate. The insert plate passes through the corresponding insertion hole. A magnet is fixedly connected to the top of the insert plate, and the bottom of the magnet is in contact with the top of the iron ring.

[0009] Preferably, the top of the mounting shell is fixedly connected to a protective sleeve that mates with the clearance hole, and several rollers are located outside the protective sleeve. A sealing ring is fixedly connected to the top of the protective sleeve, and the sealing ring is in contact with the bottom of the rotating frame.

[0010] Preferably, the sliding drive assembly includes a fixed block fixedly installed at the bottom of the first rotating shaft, a groove is provided at the bottom of the fixed block, a slider is slidably provided in the groove, a second rotating shaft is fixedly connected to the bottom of the slider, and the bottom of the second rotating shaft is rotatably connected to the mounting shell, and a drive unit that cooperates with the second rotating shaft is installed on the mounting shell.

[0011] Preferably, the drive unit includes a servo motor fixedly mounted on the outer wall of the mounting housing, a worm gear fixedly sleeved on the outside of the second rotating shaft, a worm rotatably connected inside the mounting housing, the worm and the worm gear meshing with each other, and the output end of the servo motor fixedly connected to the worm.

[0012] The beneficial effects of this utility model are as follows: The first rotating shaft is driven to rotate by a sliding drive assembly, which in turn drives the display body to rotate via a rotating frame. This allows the display body to face the ship, making it easier for people on board to see the content displayed on the display body. The rotating frame drives the rollers to move on the mounting shell. The rollers increase the stability of the display body and the rotating frame during rotation. When the display body needs to be disassembled for maintenance, the positioning structure releases the support base, and the operator drives the display body and the rotating frame upwards, allowing the first rotating shaft to drive the support base to be pulled out of the mounting shell through the clearance hole, thus completing the disassembly of the display body. Compared to a display body with a fixed angle, this greatly expands the effective viewing range, ensuring that clear warning information is visible from the front regardless of the direction the ship approaches, eliminating blind spots. The structure of the rotating frame driving the rollers to move on the mounting shell transforms the potentially suspended high-torque rotation into a rotational motion supported by rollers. This effectively reduces the load and wear of the sliding drive assembly, prevents structural fatigue of the display body due to long-term rotation, and enhances the stability of the entire device under external forces such as wind loads.

[0018] This specification provides one or more embodiments of a traffic warning display device for inland waterways, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes a display body 1 and a mounting shell 2 located below the display body 1. A rotating frame 3 is fixedly connected to the bottom of the display body 1. A support base 5 is provided inside the mounting shell 2. An avoidance hole 21 that cooperates with the support base 5 is opened on the top of the inner wall of the mounting shell 2. A first rotating shaft 6 is rotatably connected to the support base 5. The top end of the first rotating shaft 6 is fixedly connected to the bottom of the rotating frame 3. A sliding drive assembly that cooperates with the first rotating shaft 6 is installed on the mounting shell 2. Several rollers 7 are fixedly connected to the bottom of the rotating frame 3, and the bottom ends of the rollers 7 are in contact with the top of the mounting shell 2. A positioning structure adapted to the support base 5 is installed on the mounting shell 2. The operator fixes the mounting shell 2 in a preset position and drives the first rotating shaft 6 to rotate through the sliding drive assembly. The first rotating shaft 6 then drives the display body 1 to rotate through the rotating frame 3, so that the display body 1 can face the ship, making it easier for people on the ship to see the content displayed on the display body 1. The rotating frame 3 drives the rollers 7 to move on the mounting shell 2. The rollers 7 increase the stability of the display body 1 and the rotating frame 3 during rotation. When the display body 1 is disassembled and repaired, the positioning structure releases the support base 5. The operator drives the display body 1 and the rotating frame 3 to move upward, so that the first rotating shaft 6 drives the support base 5 to be pulled out of the mounting shell 2 through the clearance hole 21, thus completing the disassembly of the display body 1. Compared with the fixed angle of the display body 1, the effective viewing range is greatly expanded, ensuring that no matter which direction the ship comes from, a clear warning message can be seen in front, eliminating blind spots. The structure of the rotating frame 3 driving the roller 7 to move on the mounting shell 2 transforms the originally potentially suspended high-torque rotation into a rotational motion supported by the roller 7. This effectively reduces the load and wear of the sliding drive components, prevents structural fatigue of the display body 1 due to long-term rotation, and enhances the stability of the entire device under external forces such as wind load.

[0019] In embodiments of this utility model, such as Figure 2 , Figure 3 and Figure 4As shown, the positioning structure includes two guide posts 8 fixedly installed inside the mounting shell 2, and the guide posts 8 penetrate the support base 5. Pressing plates 9 are respectively provided on both sides of the support base 5, and inclined surfaces that cooperate with the pressing plates 9 are respectively provided at both ends of the support base 5. A stopper that cooperates with the pressing plates 9 is installed on the mounting shell 2. The stopper includes an iron ring 10 slidably sleeved on the outside of the pressing plates 9. The iron ring 10 is fixedly connected to the outer wall of the mounting shell 2. An insert plate 11 penetrates the iron ring 10, and an insertion hole 12 that cooperates with the insert plate 11 is opened on the pressing plate 9. The insert plate 11 passes through the corresponding insertion hole 12. A magnet block 13 is fixedly connected to the top of the insert plate 11, and the bottom of the magnet block 13 contacts the top of the iron ring 10. The ends of the two pressing plates 9 respectively engage with the two... The inclined surfaces are in contact, and the position of the support base 5 is limited by the pressing plate 9 to prevent the support base 5 from shaking vertically relative to the mounting shell 2. The design of the guide post 8 prevents the support base 5 from rotating and shaking relative to the mounting shell 2. When the support base 5 needs to be pulled out from the mounting shell 2, the operator drives the magnet block 13 and the insert plate 11 to move upward. The magnet block 13 is no longer magnetically attracted to the iron ring 10, and the insert plate 11 is disengaged from the insertion hole 12, releasing the fixation of the pressing plate 9. The operator drives the pressing plate 9 to move so that the end of the pressing plate 9 is no longer in contact with the support base 5, releasing the positioning fixation of the support base 5. The operator drives the display body 1 and the rotating frame 3 to move upward again. The rotating frame 3 can then drive the support base 5 to move out of the mounting shell 2 through the first rotating shaft 6, and the support base 5 is disengaged from the guide post 8.

[0020] In embodiments of this utility model, such as Figure 3 and Figure 4As shown, a protective sleeve 4 that mates with the clearance hole 21 is fixedly connected to the top of the mounting shell 2, and several rollers 7 are located outside the protective sleeve 4. A sealing ring is fixedly connected to the top of the protective sleeve 4, and the sealing ring contacts the bottom of the rotating frame 3. The sliding drive assembly includes a fixing block 14 fixedly installed at the bottom of the first rotating shaft 6. A groove 15 is provided at the bottom of the fixing block 14, and a slider 16 is slidably arranged in the groove 15. A second rotating shaft 17 is fixedly connected to the bottom of the slider 16, and the bottom of the second rotating shaft 17 is rotatably connected to the mounting shell 2. A drive unit that mates with the second rotating shaft 17 is installed on the mounting shell 2. The drive unit includes a servo motor 20 fixedly installed on the outer wall of the mounting shell 2. A worm gear 18 is fixedly sleeved on the outside of the second rotating shaft 17. A worm gear 19 is rotatably connected inside the housing 2. The worm gear 19 meshes with the worm wheel 18, and the output end of the servo motor 20 is fixedly connected to the worm gear 19. The servo motor 20 drives the worm gear 19 to rotate, which in turn drives the second rotating shaft 17 to rotate via the worm wheel 18. The second rotating shaft 17 drives the first rotating shaft 6 to rotate synchronously via the slider 16 and the fixing block 14. When the positioning structure releases the positioning and fixing of the support seat 5, the operator drives the support seat 5 to be pulled out of the housing 2. The support seat 5 drives the fixing block 14 to move upward relative to the slider 16, and the slider 16 slides out of the groove 15, thus completing the removal of the support seat 5. The protective sleeve 4 and the sealing ring are designed to block the clearance hole 21, reducing the possibility of impurities entering the housing 2 through the clearance hole 21.
