Description

Technical Field

[0001] This utility model belongs to the field of navigation mark technology, specifically a height adjustment device for navigation marks. Background Technology

[0002] Navigation aids are visual, acoustic, and radio navigational facilities installed to help ships navigate safely, economically, and conveniently. They are important guides for maritime traffic and are of great significance in ensuring the safety of ship navigation and maintaining maritime traffic order. Visual navigation aids are the most commonly used.

[0003] Existing visual navigation aids include fixed marks and water marks. Fixed marks include lighthouses, beacons, buoys, and bridge navigation aids. These marks are usually placed in fixed locations such as coastlines, ports, or waterways to provide ships with stable navigation information. Water marks include light buoys, large light buoys, lightships, and articulated light beacons. These marks float on the water and are securely anchored to the seabed at predetermined points by anchors, sinkers, or chains to provide ships with dynamic navigation information.

[0004] Currently, most visual navigational aids in existing technologies are at a fixed height. Even if they can be adjusted, they are adjusted before use. This method is not complicated for adjusting fixed aids, but for waterborne aids, the aids need to be adjusted and then moved to a designated position, or the operator needs to move to a designated position before adjustment. This is more complicated to operate and its adaptability needs to be improved.

[0005] Therefore, a height adjustment device for navigation marks is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the problems mentioned above, which require adjusting the water beacon and then moving it to a designated position, or having the operator move to a designated position before adjusting it, making the operation relatively complicated and lacking in adaptability, a height adjustment device for navigational aids is proposed.

[0008] Preferably, the fixed vertical column and the hemispherical base are positioned directly above the center of the inverted pot-shaped floating bucket, and multiple auxiliary support legs are fixedly connected to the surface of the hemispherical base, with the multiple auxiliary support legs evenly arranged around the circumference of the surface of the hemispherical base.

[0009] Preferably, a rotating frame is fixedly connected to the inner side of the inverted pot-shaped float, and a damper is rotatably connected to the surface of the rotating frame. The end of the damper away from the rotating frame is rotatably connected to the surface of the connecting seat.

[0010] Preferably, the number of the rotating frame and the damper is set to four, and the four rotating frames and dampers are evenly arranged around the circumference of the surface of the connecting card seat.

[0011] Preferably, a hollow pontoon is fixedly connected to the bottom of the inverted pot-shaped pontoon, and a semi-circular groove is provided on the top of the hollow pontoon. The bottom of the hemispherical base fits into the interior of the semi-circular groove, and the surface of the hemispherical base is in rolling connection with the inner wall of the semi-circular groove.

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.

[0026] Specific implementation examples are given below.

[0027] Please see Figures 1-6This utility model provides a height adjustment device for a navigation beacon, including a fixed vertical column 1 and an inverted pot-shaped float 2; a hemispherical base 3 is fixedly connected to the bottom end of the fixed vertical column 1, a connecting bracket 4 is fixedly connected to the top surface of the fixed vertical column 1, a hydraulic cylinder 5 is fixedly connected to the bottom of the inner wall of the fixed vertical column 1, a lifting seat 6 is fixedly connected to the top of the hydraulic cylinder 5, a limiting support rod 7 is fixedly connected to the top of the connecting bracket 4, an auxiliary cylindrical groove 8 adapted to the limiting support rod 7 is opened inside the lifting seat 6, the surface of the limiting support rod 7 is slidably connected to the inner wall of the auxiliary cylindrical groove 8, a supporting column 9 is fixedly connected to the top of the lifting seat 6, and a navigation beacon body 10 is fixedly connected to the top of the supporting column 9; during operation, the bottom of the fixed vertical column 1 is fixed to the hemispherical base 3, and the height adjustment device is adjusted by the following: The hemispherical base 3 supports the fixed column 1, which is a hollow column. The hydraulic cylinder 5 is located inside the fixed column 1. When height adjustment is required, the hydraulic cylinder 5 extends and lifts the lifting seat 6, thereby driving the top support column 9 and the navigation mark body 10 to rise and fall, achieving the height adjustment function. During this process, the limiting support rod 7 is fixed to the top of the lifting seat 6, and at the same time, the limiting support rod 7 can slide inside the auxiliary cylindrical slide groove 8. The whole system can be automatically adjusted by setting the hydraulic cylinder 5 and the lifting seat 6. The operation is simple. For water markers, it can be adjusted in real time. At the same time, the limiting support rod 7 and the auxiliary cylindrical slide groove 8 can maintain the stability during lifting and falling, improving the adaptability during use.

[0028] Furthermore, such as Figure 1 and Figure 4As shown, the fixed vertical column 1 and the hemispherical base 3 are positioned directly above the center of the inverted pot-shaped float 2. Multiple auxiliary support legs 11 are fixedly connected to the surface of the hemispherical base 3, and the multiple auxiliary support legs 11 are evenly arranged around the circumference of the surface of the hemispherical base 3. A rotating frame 12 is fixedly connected to the inner side of the inverted pot-shaped float 2, and a damper 13 is rotatably connected to the surface of the rotating frame 12. The end of the damper 13 away from the rotating frame 12 is rotatably connected to the surface of the connecting seat 4. The number of rotating frames 12 and dampers 13 is set to four, and the four rotating frames 12 and dampers 13 are evenly arranged around the circumference of the surface of the connecting seat 4. During operation, the inverted pot-shaped float 2 has a central opening, while the fixed vertical column 1 and hemispherical base 3 are located at the center of the inverted pot-shaped float 2. Multiple auxiliary support legs 11 arranged in a circular pattern are fixed on the surface of the hemispherical base 3. The rotating frame 12 is fixed on the inverted pot-shaped float 2 and is supported by the inverted pot-shaped float 2. The damper 13 can rotate on the rotating frame 12, and its other end is rotatably connected to the surface of the connecting bracket 4. The damper 13 is used to buffer the connecting bracket 4. By setting the damper 13 and evenly circumferentially arranged on the surface of the connecting bracket 4, it can buffer the wind and restore the vertical state. At the same time, the auxiliary support legs 11 fixed on the surface of the hemispherical base 3 can support the fixed vertical column 1 when it is blown by the wind and the degree of deflection is large, so as to prevent it from overturning and ensure the stability during use.

[0029] Furthermore, such as Figure 1 and Figure 6 As shown, a hollow pontoon 14 is fixedly connected to the bottom of the inverted pot-shaped pontoon 2. A semi-circular groove 15 is provided on the top of the hollow pontoon 14. The bottom of the hemispherical base 3 is attached to the inside of the semi-circular groove 15. The surface of the hemispherical base 3 is in rolling connection with the inner wall of the semi-circular groove 15. A hollow rod 16 is fixedly connected to the bottom of the hollow pontoon 14. The bottom end of the hollow rod 16 is connected to a hollow auxiliary buoy 17. During operation, the hollow float 14 is fixed to the bottom of the inverted pot-shaped float 2. The hollow float 14 has a certain buoyancy and can float on the water surface. At the same time, the outer perimeter of the inverted pot-shaped float 2 extends beyond the surface of the hollow float 14, increasing the buoyancy and preventing water from flooding the surface of the hollow float 14. This ensures that the inverted pot-shaped float 2 and the part above it can always stay on the water surface. The hollow rod 16 and the hollow auxiliary float 17 both have a certain buoyancy, improving the floating effect. During installation, the rope is fixed to the hollow rod 16 and the hollow auxiliary float 17 to prevent the hollow float 14 from drifting away.

[0030] Working Principle: Since the water marker requires adjustment before being moved to a designated position, or the operator needs to move to a designated position before adjustment, the operation is relatively complex and its adaptability needs improvement. First, the bottom of the fixed vertical column 1 is fixed to the hemispherical base 3, which supports the fixed vertical column 1. The fixed vertical column 1 is a hollow column, and the hydraulic cylinder 5 is located inside it. When height adjustment is needed, the hydraulic cylinder 5 extends and lifts the lifting seat 6, thereby driving the top supporting column 9 and the buoy body 10 to rise and fall, achieving height adjustment. During this process, the limiting strut 7 is fixed to the top of the lifting seat 6, and can also slide inside the auxiliary cylindrical slide 8. The entire system, through the hydraulic cylinder 5 and the lifting seat 6, can automatically adjust, making operation simple. For water markers, real-time adjustment is possible. Furthermore, the limiting strut 7, in conjunction with the auxiliary cylindrical slide 8, maintains stability during lifting and falls, improving its adaptability. Meanwhile, the inverted pot-shaped float 2 has a central opening, while the fixed vertical column 1 and the hemispherical base 3 are located at the center of the inverted pot-shaped float 2. Multiple auxiliary support legs 11 arranged in a circular pattern are fixed on the surface of the hemispherical base 3, and the rotating frame 12 is fixed on the inverted pot-shaped float 2. The inverted pot-shaped float 2 supports the rotating frame 12. The damper 13 can rotate on the rotating frame 12, and its other end is rotatably connected to the surface of the connecting bracket 4. The damper 13 is used to buffer the connecting bracket 4. By setting the damper 13 and evenly circumferentially arranged on the surface of the connecting bracket 4, it can buffer the wind and restore the vertical state. At the same time, the auxiliary support legs 11 are fixed on the surface of the hemispherical base 3, which can support the fixed vertical column 1 when it is blown by the wind and the degree of deflection is large, preventing it from overturning and ensuring the stability during use. Finally, the hollow float 14 is fixed to the bottom of the inverted pot-shaped float 2. The hollow float 14 has a certain buoyancy and can float on the water surface. At the same time, the outer perimeter of the inverted pot-shaped float 2 extends beyond the surface of the hollow float 14, increasing the buoyancy and preventing water from flooding the surface of the hollow float 14. This ensures that the inverted pot-shaped float 2 and the part above it can always stay on the water surface. The hollow rod 16 and the hollow auxiliary float 17 both have a certain buoyancy, improving the floating effect. During installation, the rope is also fixed to the hollow rod 16 and the hollow auxiliary float 17 to prevent the hollow float 14 from drifting away.
