Description

Technical Field

[0001] This invention relates to the field of navigation aids technology, specifically an adjustable anchoring device for AIS navigation aids and its adjustment method. Background Technology

[0002] AIS (Automatic Identification System) navigation aids are intelligent navigational aids that integrate AIS technology. They can broadcast navigation aid dynamics and waterway information in real time, providing ships with precise positioning and navigation services. In practical applications, to ensure that the navigation aid remains in place stably in complex sea conditions, it must be equipped with a reliable anchoring device (connected to an underwater anchor block via an anchor chain) to fix the buoy at the designed location.

[0003] However, traditional anchoring devices mostly use fixed-length anchor chains. When the ambient wind speed increases and the waves intensify, the taut anchor chain will directly transmit the impact force to the anchor point, forming a strong anchor pull effect. This may not only cause the buoy to capsize or shift instantly, but may even cause the anchor chain to break and fail. In response, some devices have added anchor chain retraction and extension mechanisms to try to buffer the horizontal load by extending the anchor chain length. However, their function is still limited. They only enhance the horizontal anti-displacement capability, but fail to simultaneously improve the anti-capsulation and recovery moment of the buoy body. As a result, the buoy is very easy to capsize under the impact of huge waves. At the same time, due to the lack of a vertical load dissipation mechanism, it is also unable to effectively offset the downward impact of the waves. The overall safety of the anchoring system still has considerable room for improvement. Summary of the Invention

[0007] As described above, the adjustable anchoring device for AIS navigation marks includes a transmission structure that is rotatably mounted on the base. The transmission shaft is connected to the rotating shaft of the take-up roller via a bevel gear set and is also connected to the threaded rod via a connecting belt.

[0008] As described above, the adjustable anchoring device for AIS navigation beacons includes a sliding guide mechanism comprising an assembly arm that is slidably and sealed to the base. The assembly arm is L-shaped, with one end fixed to the float and the other end connected to the sleeve via a push-pull structure.

[0009] The AIS beacon adjustable anchoring device as described above: the push-pull structure includes a guide rail fixed to the top wall of the base and arranged radially along the base, a movable block slidably fitted on the guide rail, and a connecting rod connecting the movable block and the sleeve; wherein, the movable block is fixed to the assembly arm, and the two ends of the connecting rod are respectively hinged to the sleeve and the movable block.

[0010] As described above, the adjustable anchoring device for AIS navigation beacons includes an inflation mechanism comprising a bellows disposed within the base via an elastic assembly structure, the bellows being connected to the airbag via a transmission pipe assembly; the elastic assembly structure cooperates with the sleeve, the sleeve being able to cause the elastic assembly structure to perform a compression action on the bellows, so that the bellows inflates the airbag via the transmission pipe assembly.

[0011] As described above, the adjustable anchoring device for AIS navigation beacons includes a first ring and a second ring that are respectively sealed and connected to both ends of the bellows. The first ring is fixed to the top wall of the base, and the second ring abuts against a support arm fixed to the sleeve. The first ring and the second ring are respectively provided with a first protrusion and a second protrusion. A guide post is fixedly connected to the first protrusion, and the guide post is slidably connected to the second protrusion. A cylindrical spring is also sleeved on the outer periphery of the guide post, and the two ends of the cylindrical spring are respectively connected to the first protrusion and the second protrusion.

[0012] As described above, the adjustable anchoring device for AIS navigation marks includes a first pipe fixed inside the base and communicating with the corrugated pipe, a second pipe fixed on the assembly arm and sealingly slidingly fitted with the first pipe, and a third pipe sealingly slidingly fitted with the second pipe and connected to the airbag. The third pipe is connected to the depth switching mechanism and also sealingly slidingly connected to the float.

[0013] As described above, the adjustable anchoring device for AIS navigation marks includes a depth switching mechanism comprising a slider slidably mounted on the assembly arm and fixed to the third pipe fitting, and two limiting rods fixed to the outer wall of the base and located on both sides of the assembly arm; wherein the limiting rods are inclined and have through grooves, and a protruding post is fixed to the side of the slider, the protruding post passing through the through groove and slidably connected to the limiting rods.

[0014] An adjustment method for the adjustable anchoring device of the AIS navigation beacon includes the following steps: Step 1: The wind speed sensor detects an increase in wind speed, and the traction control mechanism releases and lengthens the anchor chain; Step 2: The traction control mechanism drives the threaded rod to rotate, and the sleeve engages with the threaded rod.

When the anchor chain is extended, the sleeve drives the floats to move radially away from the base through the sliding guide mechanism. Through the expansion of multiple floats, the overall coverage of the base can be increased, and the overall stability performance can be improved. Secondly, by setting airbags, when multiple floats perform the expansion action, the inflation mechanism and the depth switching mechanism are triggered. The former inflates the airbags, and the latter increases the depth of the airbags in the water. The additional buoyancy generated by the airbags can offset the downward load of giant waves on the navigation beacon in real time. Moreover, the airbags submerged in water are subject to the viscous resistance of the water, forming a passive damping effect similar to the anti-roll fins of ships. This can efficiently dissipate wave energy, reduce the roll angle, provide protection for the anchor chain and anchor blocks, make the anchoring system more gentle, reduce the risk of anchor chain breakage during surges, and improve the overall anti-capsulation, anti-displacement, and anti-sinking efficiency of the AIS navigation beacon.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0020] Please see Figures 1-9 In this embodiment, an adjustable anchoring device for AIS navigation beacons includes a base 1, a support frame 2 fixed on the base 1, and a navigation beacon light 3 and a wind speed sensor 4 mounted on the support frame 2. The adjustable anchoring device further includes an anchor block 8 movably positioned below the base 1. The anchor block 8 is connected to a traction control mechanism mounted on the support frame 2 via an anchor chain 7. The traction control mechanism is connected to a threaded rod 12 rotatably installed within the base 1. A sleeve 13 is fitted onto the threaded rod 12, and the sleeve 13 is threadedly connected to the threaded rod 12. Multiple floats 22 are circumferentially and equidistantly arranged on the outer side of the base 1. Each float 22 is connected to a sleeve 13 through a set of sliding guide mechanisms. The sleeve 13 can drive the floats 22 to move radially along the base 1 through the sliding guide mechanisms, so that the multiple floats 22 can perform opening and closing actions. An airbag 21 is provided at the bottom of the floats 22. When the multiple floats 22 perform expansion actions, the depth switching mechanism and the inflation mechanism connected to the airbag 21 are triggered. The depth switching mechanism can cause the airbag 21 to move down, and the inflation mechanism can inflate the airbag 21.

[0021] In this embodiment, it should be further explained that, in actual use, the wind speed sensor 4 is used to monitor the wind speed in real time, thereby reflecting the size of the waves at sea. When the wind speed sensor 4 detects a high wind speed, the traction control mechanism operates to release the anchor chain 7, increasing the length of the anchor chain 7 and improving the anchoring force utilization rate. At the same time, the traction control mechanism drives the threaded rod 12 to rotate, thereby engaging the threaded rod 12 with the sleeve 13, causing the sleeve 13 to move upward on the threaded rod 12. Furthermore, the sleeve 13 will drive the float 22 to move radially away from the base 1 along the base 1 via the sliding guide mechanism, and the multiple floats 22 will perform an expansion action to increase the coverage area of ​​the multiple floats 22, thereby effectively improving the stability of the base 1; secondly, the sleeve 13 will also cause the inflation mechanism and the depth switching mechanism to be triggered, the inflation mechanism will inflate the airbag 21, and the depth switching mechanism will cause the airbag 21 to move downward, increasing the depth of the airbag 21 in the water.

[0022] Therefore, by equipping the base 1 with multiple buoys 22 evenly distributed along the circumference, when the anchor chain 7 is extended, the sleeve 13 drives the buoys 22 to move radially away from the base 1 through the sliding guide mechanism. The expansion of the multiple buoys 22 increases the overall coverage of the base 1 and improves the overall stability. Secondly, by setting an airbag 21, when the multiple buoys 22 perform the expansion action, the inflation mechanism and the depth switching mechanism are triggered. The former inflates the airbag 21, and the latter increases the depth of the airbag 21 in the water. The additional buoyancy generated by the airbag 21 can offset the downward load of the giant waves on the navigation mark in real time. Moreover, the airbag 21 submerged in water is subject to the viscous resistance of the water, forming a passive damping effect similar to the anti-roll fin of a ship. This can efficiently dissipate wave energy, reduce the roll angle, provide protection for the anchor chain 7 and the anchor block 8, make the anchoring force more gentle, reduce the risk of the anchor chain 7 breaking during surges, and improve the overall anti-capsulation, anti-displacement, and anti-sinking efficiency of the AIS navigation mark.

[0023] As a further embodiment of the present invention, please refer again. Figure 2 and Figure 3 The traction control mechanism includes a take-up roller 6 rotatably mounted on the upright 2. The take-up roller 6 is used to wind up the anchor chain 7. The threaded rod 12 is hollow, and the anchor chain 7 passes through the threaded rod 12 and is connected to the anchor block 8. A drive motor 5 is installed on the side of the upright 2. The output end of the drive motor 5 is connected to the rotating shaft of the take-up roller 6. The rotating shaft of the take-up roller 6 is also connected to the threaded rod 12 through a transmission structure.

[0024] The transmission structure includes a transmission shaft 10 rotatably mounted on the base 1. The transmission shaft 10 is connected to the rotating shaft of the take-up roller 6 via a bevel gear set 9, and is also connected to the threaded rod 12 via a connecting belt 11.

[0025] In this embodiment, it should be noted that the connecting belt 11 is selected as a transmission chain or toothed belt to ensure stable transmission. Specifically, the bevel gear set 9 includes a first bevel gear fixedly installed coaxially with the take-up roller 6 and a second bevel gear fixed on the transmission shaft 10. The second bevel gear meshes with the first bevel gear. When the drive motor 5 is working, it can drive the take-up roller 6 to rotate, thereby controlling the length of the anchor chain 7 released. While the take-up roller 6 rotates, its rotation shaft will drive the transmission shaft 10 to rotate through the bevel gear set 9. The transmission shaft 10 drives the threaded rod 12 to rotate through the connecting belt 11, so that the threaded rod 12 and the sleeve 13 are threadedly engaged. The sleeve 13 moves up or down on the threaded rod 12, thereby causing the sliding guide mechanism to drive the float 22 to move radially along the base 1. The inflation mechanism and the depth switching mechanism are triggered to realize the synchronous control of the state of the airbag 21.

[0026] As a further embodiment of the present invention, please refer again. Figure 7 and Figure 8 The sliding guide mechanism includes an assembly arm 16 that is slidably and sealed to the base 1. The assembly arm 16 is L-shaped, with one end fixed to the float 22 and the other end connected to the sleeve 13 via a push-pull structure.

[0027] The push-pull structure includes a guide rail 14 fixed to the top wall of the base 1 and arranged radially along the base 1, a movable block 15 slidably fitted on the guide rail 14, and a connecting rod 17 connecting the movable block 15 and the sleeve 13; the movable block 15 is fixed to the assembly arm 16, and the two ends of the connecting rod 17 are respectively hinged to the sleeve 13 and the movable block 15.

[0028] In this embodiment, when the take-up roller 6 rotates and releases the anchor chain 7, the sleeve 13 engages with the threaded rod 12, and the sleeve 13 moves upward on the threaded rod 12. Consequently, the sleeve 13 can push the movable block 15 to slide away from the threaded rod 12 on the guide rail 14 via the connecting rod 17. Correspondingly, the assembly arm 16 slides towards the outside of the base 1, causing the float 22 to move away from the base 1. The multiple floats 22 then perform an expansion action, increasing the overall coverage area of ​​the base 1 and improving overall stability.

[0029] As a further embodiment of the present invention, please refer again. Figure 5 and Figure 9The inflation mechanism includes a corrugated tube 27 disposed in the base 1 via an elastic assembly structure. The corrugated tube 27 is connected to the airbag 21 via a transmission tube assembly. The elastic assembly structure cooperates with the sleeve 13. The sleeve 13 can cause the elastic assembly structure to perform a compression action on the corrugated tube 27, so that the corrugated tube 27 inflates the airbag 21 through the transmission tube assembly.

[0030] The elastic assembly structure includes a first ring 24 and a second ring 25 that are respectively sealed and connected to both ends of the bellows 27. The first ring 24 is fixed to the top wall of the base 1, and the second ring 25 abuts against the support arm 1301 fixed to the sleeve 13. The first ring 24 and the second ring 25 are respectively formed with a first protrusion 2401 and a second protrusion 2501. The first protrusion 2401 is fixedly connected to a guide post 26, and the guide post 26 is slidably connected to the second protrusion 2501. A columnar spring 23 is also sleeved on the outer periphery of the guide post 26, and the two ends of the columnar spring 23 are respectively connected to the first protrusion 2401 and the second protrusion 2501.

[0031] In this embodiment, when the sleeve 13 and the threaded rod 12 are threaded together and move upward within the base 1, the support arm 1301 applies pressure to the second ring 25, causing the second ring 25 to move closer to the first ring 24. The cylindrical spring 23 is compressed, causing the air in the bellows 27 to be discharged and enter the airbag 21 through the transmission pipe assembly, thus completing the inflation of the airbag 21.

[0032] As a further embodiment of the present invention, the transmission tube assembly includes a first tube 18 fixed in the base 1 and communicating with the corrugated pipe 27, a second tube 19 fixed on the assembly arm 16 and sealingly slidingly fitted with the first tube 18, and a third tube 20 sealingly slidingly fitted with the second tube 19 and connected to the airbag 21. The third tube 20 is connected to the depth switching mechanism and also sealingly slidingly connected to the float 22.

[0033] As a further embodiment of the present invention, please refer again. Figure 4 The depth switching mechanism includes a slider 28 slidably mounted on the assembly arm 16 and fixed to the third tube 20, and two limiting rods 29 fixed to the outer wall of the base 1 and located on both sides of the assembly arm 16 respectively; wherein, the limiting rods 29 are inclined and have through grooves 2901 thereon, and the side of the slider 28 is fixed with a protrusion 2801, the protrusion 2801 passing through the through groove 2901 and slidably connected to the limiting rods 29.

[0034] In this embodiment, when the float 22 moves away from the base 1, that is, the assembly arm 16 slides towards the outside of the base 1, the first tube 18 and the second tube 19 slide relative to each other. At the same time, the protrusion 2801 slides with the limiting rod 29 through the through groove 2901, the slider 28 makes room and slides relative to the assembly arm 16, that is, the slider 28 slides upward on the assembly arm 16, and the slider 28 drives the third tube 20 and the airbag 21 to move downward (the third tube 20 slides relative to the second tube 19), so that the depth of the airbag 21 increases, ensuring that the airbag 21 effectively improves the stability of the anchor system.

[0035] An adjustment method for the adjustable anchoring device of the AIS navigation beacon includes the following steps: Step 1: The wind speed sensor 4 detects an increase in wind speed, and the traction control mechanism releases and lengthens the anchor chain 7. Step 2: The traction control mechanism drives the threaded rod 12 to rotate. The sleeve 13 is threadedly engaged with the threaded rod 12. The sliding guide mechanism drives the float 22 away from the base 1, and the multiple floats 22 perform an expansion action. Step 3: Sleeve 13 triggers the inflation mechanism and depth switching mechanism. The inflation mechanism inflates the airbag 21, and the depth switching mechanism increases the depth of the airbag 21 in the water.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
