Abstract
Description
Technical Field
[0001] This application relates to the field of marine observation technology, and in particular to a vibration-damping cable guide device and a bottom-mounted observation system. Background Technology
[0002] The wave-dissipating structure of deep-sea marine ranches typically employs a ring-shaped array of precast reinforced concrete cylinders, forming a protective barrier around the net cages to effectively resist environmental loads such as wind, waves, and currents. To ensure the safe operation and maintenance of the marine ranch, a bottom-mounted observation system is required to monitor key hydrological parameters such as waves and current velocity in the sea area surrounding the wave-dissipating structure in real time. Since the operating area is far from land and vessels must be evacuated during typhoons, the observation system must have independent power supply and remote real-time communication capabilities. Therefore, an operation and maintenance station is set up on top of the wave-dissipating structure, integrating data interfaces and a power supply battery compartment to support long-term unattended monitoring.
[0003] However, a key challenge of this system is that the cable connecting the bottom-mounted observation system to the surface terminal (used to transmit data from the underwater acoustic Doppler current profiler ADCP) is prone to severe linear vibration under strong winds and waves. This vibration causes continuous friction and compression between the cable and the edge of the wave-damping cylinder, leading to sheath damage, internal cable breakage, and ultimately signal transmission interruption. Utility Model Content
[0004] This application provides an anti-shake cable guide device and a bottom-mounted observation system to solve the problems existing in related technologies. The technical solution is as follows: In a first aspect, embodiments of this application provide a vibration-damping cable guide device, which is configured on a wave-damping structure and includes: A cable guide body, mounted on a wave-damping structure, has cable guide holes extending through both ends of the cable guide body along its length, for cable passage. Positioning grooves are provided at both ends of the cable guide body along its length, extending through both sides of the cable guide body along its width, and communicating with the cable guide holes. Two limiting cover plates are provided, each of which is disposed on a corresponding positioning groove. The limiting cover plate closes the corresponding positioning groove and the communication channel between the positioning groove and the end opening of the cable guide hole. Both ends of the limiting cover plate along the width direction of the cable guide body are connected to the wave-damping structure. The limiting cover plate has a limiting hole located on the side of the limiting cover plate that closes the communication channel. The limiting hole communicates with the cable guide hole and is adapted to the cable.
[0005] In one embodiment, the cable guide body is a straight structure, and the cable guide body is arranged parallel to the axial direction of the wave-damping structure's cylinder.
[0006] In one embodiment, the cross-section of the cable guide body is hexagonal.
[0007] In one embodiment, the cable guide body is provided with a bottom plate, a top plate, side plates, and inclined plates. The bottom plate is connected to a wave-damping structure, and the top plate is spaced apart from the bottom plate. There are two side plates, which are placed on both sides of the width direction of the bottom plate. There are also two inclined plates, which are placed on both sides of the width direction of the top plate. Each inclined plate connects the top plate and the corresponding side plate. The bottom plate, the top plate, the side plates, and the inclined plates form the cable guide hole.
[0008] In one embodiment, the width of the base plate is greater than the width of the top plate.
[0009] In one embodiment, the anti-vibration cable guide device further includes: Multiple connectors are arranged at intervals along the length of the cable guide body, each connector covers the cable guide body, and both ends of each connector along the width of the cable guide body are connected to a wave-damping structure.
[0010] In one embodiment, both the cable guide body and the connector are made of stainless steel.
[0011] In one embodiment, the limiting cover plate is provided with a first sealing plate portion, a second sealing plate portion, and a connecting portion. The first sealing plate portion closes the corresponding positioning groove. The first sealing plate portion is provided with the connecting portion on both sides along the width direction of the cable guide body. The connecting portion is connected to the wave-damping structure. The second sealing plate portion is connected to the first sealing plate portion and closes the communicating channel. The second sealing plate portion has the cable guide hole.
[0012] In one embodiment, the limiting cover is made of hard rubber.
[0013] Secondly, embodiments of this application provide a bottom-mounted observation system, including the aforementioned anti-shake cable device.
[0014] The advantages or beneficial effects of the above technical solutions include at least the following: This utility model's anti-vibration cable guide device, through the coordinated operation of the cable guide body and the limiting cover plate, achieves full axial limiting and radial constraint of the underwater acoustic Doppler current profiler data cable, effectively suppressing displacement caused by environmental loads and preventing cable vibration. The cable guide body has a cable guide hole for the cable to pass through, providing full axial protection and limiting functions. The limiting cover plate, through its design with a positioning groove, seals the positioning groove and the connecting channel between the positioning groove and the end opening of the cable guide hole. Simultaneously, it connects both ends of the limiting cover plate to the wave-damping structure, enhancing the overall structural integrity and improving the constraint stability of the cable, thus improving the anti-displacement and anti-vibration effect. Furthermore, the limiting hole of the limiting cover plate is adapted to the cable and allows the cable to pass through the cable guide body. Axial limiting and radial constraint at both ends of the cable reliably fix the cable to the cable guide body, preventing friction or compression of the cable against the edge of the wave-damping structure due to environmental loads, preventing damage to the cable sheath and breakage of internal cables, and ensuring the cable's long-term stable operation in complex environments.

[0019] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0020] See Figures 1-7 This invention illustrates a preferred embodiment of an anti-vibration cable guide device, which is used to be mounted on a wave-damping structure and includes: A cable guide body 1 is mounted on a wave-damping structure. The cable guide body 1 has a cable guide hole 11 that extends through both ends of the cable guide body 1 along its length, allowing a cable 5 to pass through. Positioning grooves 12 are provided at both ends of the cable guide body 1 along its length, extending through both sides of the cable guide body 1 along its width and connecting to the cable guide hole 11. Two limiting cover plates 2 are provided on the corresponding positioning groove 12. The limiting cover plate 2 closes the corresponding positioning groove 12 and the communication channel between the positioning groove 12 and the end opening of the cable guide hole 11. That is, the limiting cover plate 2 closes both the positioning groove 12 and the communication channel between the positioning groove 12 and the end opening of the cable guide hole 11. Both ends of the limiting cover plate 2 along the width direction of the cable guide body 1 are connected to the wave-damping structure. The limiting cover plate 2 has a limiting hole 221. The limiting hole 221 is located on the side of the limiting cover plate 2 that closes the communication channel. The limiting hole 221 is connected to the cable guide hole 11 and is adapted to the cable 5.
[0021] This utility model's anti-vibration cable guide device, through the coordinated cooperation of the cable guide body 1 and the limiting cover plate 2, achieves full axial limiting and radial constraint of the underwater acoustic Doppler current profiler data cable 5, effectively suppressing displacement caused by environmental loads and preventing cable 5 vibration. The cable guide body 1 has a cable guide hole 11 for the cable 5 to pass through, providing full axial protection and limiting functions. The limiting cover plate 2, through its cooperation with the positioning groove 12, seals the positioning groove 12 and the connecting channel between the positioning groove 12 and the end opening of the cable guide hole 11, while simultaneously... The limiting cover plate 2 is connected to the wave-damping structure at both ends, which enhances the overall structure and improves the constraint stability of the cable 5, thereby improving the anti-displacement and anti-vibration effect. At the same time, the limiting hole 221 of the limiting cover plate 2 is adapted to the cable 5 and allows the cable 5 to pass through the cable guide body 1. By limiting the axial and constraining the two ends of the cable 5, the cable 5 is reliably fixed to the cable guide body 1, avoiding friction or squeezing between the cable 5 and the edge of the wave-damping structure due to environmental load, preventing damage to the cable sheath and breakage of the internal cable, and ensuring that the cable 5 can work stably and continuously in complex environments.
[0022] It should be noted that in practical applications, armored cables 5 with a diameter ≤100mm can be used in conjunction with underwater burial measures to work together with the anti-vibration cable guide device to suppress the swaying of the cable 5.
[0023] It should be noted that the gap between the limiting hole 221 and the guide cable 5 is less than 1mm, so as to restrict mud and sand from entering the interior of the guide cable body 1 through the gap between the limiting hole 221 and the guide cable 5.
[0024] See Figures 1-7 In one embodiment, the cable guide body 1 has a straight structure and is arranged parallel to the axial direction of the wave-damping structure's cylinder 4. The straight cable guide body 1 has no bending or turning angle design, which can not only guide the cable 5 in a straight line and limit its axial movement, but also conform to the outer contour of the wave-damping structure's cylinder 4, effectively eliminating bending stress concentration of the cable 5 while ensuring the overall stability of the structure.
[0025] See Figures 1-7 In one embodiment, the cable guide body 1 has a hexagonal cross-section. The hexagonal cross-section of the cable guide body 1 enhances its structural strength and resistance to deformation, ensuring that the cable guide body 1 can be stably installed on the wave-damping structure, improving the anti-displacement and anti-vibration effects, while facilitating installation and positioning, and providing multi-directional constraints to better stabilize the cable 5.
[0026] See Figures 1-7In one embodiment, the cable guide body 1 includes a base plate 13, a top plate 14, side plates 15, and inclined plates 16. The base plate 13 is connected to the wave-damping structure, and the top plate 14 is spaced apart from the base plate 13. Two side plates 15 are provided, positioned on either side of the base plate 13 in the width direction. Two inclined plates 16 are provided, positioned on either side of the top plate 14 in the width direction. Each inclined plate 16 connects the top plate 14 to its corresponding side plate 15. The base plate 13, top plate 14, side plates 15, and inclined plates 16 form a cable guide hole 11. Thus, the cable guide hole 11 is formed by the combined structure of the base plate 13, top plate 14, side plates 15, and inclined plates 16. The connection between the base plate 13 and the wave-damping structure ensures overall stability, and the top plate 14 and side plates 15 form a stable support structure through the inclined plates 16, enhancing the rigidity and deformation resistance of the cable guide body 1. Simultaneously, the spatial layout of the cable guide hole 11 is optimized to provide more reliable cable 5 constraint and protection.
[0027] See Figures 1-7 In one embodiment, the width of the base plate 13 is greater than the width of the top plate 14. By widening the base plate 13, the connection stability between the cable guide body 1 and the wave-damping structure is enhanced. At the same time, a trapezoidal structure that is narrower at the top and wider at the bottom is formed, which improves the overall anti-overturning ability and load distribution uniformity, thereby further enhancing the anti-displacement and anti-vibration effects.
[0028] Of course, in other embodiments, the cross-section of the cable guide body 1 can be rectangular, pentagonal or other irregular shapes.
[0029] In one embodiment, the cable guide body 1 is made of stainless steel. Using stainless steel to make the cable guide body 1 ensures both high structural strength and corrosion resistance, and also enables it to adapt to harsh underwater environments, ensuring long-term stable operation.
[0030] In one embodiment, the cable guide body 1 is made of 316 stainless steel. Using 316 stainless steel to make the cable guide body 1 gives it excellent resistance to seawater corrosion and higher mechanical strength, making it particularly suitable for long-term use in marine environments. It effectively resists seawater erosion and maintains structural stability.
[0031] In one embodiment, the cable guide body 1 is fixed to the outer wall of the wave-damping structure cylinder 4 by welding, ensuring a firm and reliable connection, improving the overall structural strength and stability, and enabling the cable guide body 1 to effectively resist vibration and impact loads in the marine environment, thereby further improving the anti-displacement and anti-vibration effects.
[0032] Of course, in other embodiments, the cable guide body 1 can also be connected to the cylinder 4 of the wave-damping structure by a plurality of first fastening screws or first fastening bolts.
[0033] See Figures 1-7In one embodiment, the anti-vibration cable guide device further includes: Multiple connectors 3 are arranged at intervals along the length of the cable guide body 1. Each connector 3 covers the cable guide body 1, and both ends of each connector 3 along the width of the cable guide body 1 are connected to the wave-damping structure. The multiple connectors 3 spaced apart along the length of the cable guide body 1 achieve dual reinforcement, enhancing the overall connection strength between the cable guide body 1 and the wave-damping structure, and forming multi-point distributed constraints. This effectively improves the bending stiffness of the cable guide body 1, thereby effectively enhancing its vibration resistance and structural stability, ensuring the reliable fixation of the cable 5 in dynamic environments.
[0034] In one embodiment, adjacent connectors 3 are spaced 5m apart to further enhance the structural stability of the long-span cable conductor 1.
[0035] In one embodiment, the connector 3 is made of stainless steel. Using stainless steel to make the connector 3 ensures the high strength and corrosion resistance of the connector 3 structure, and can adapt to the harsh underwater environment, ensuring long-term stable operation, so that the cable guide body 1 can be permanently and stably fixed on the wave-damping structure cylinder 4.
[0036] In one embodiment, the connector 3 is made of 316 stainless steel. Using 316 stainless steel to make the connector 3 gives it excellent resistance to seawater corrosion and higher mechanical strength, making it particularly suitable for long-term use in marine environments. It effectively resists seawater erosion and maintains structural stability.
[0037] In one embodiment, the connector 3 is connected to the cable guide body 1 by welding, and the connector 3 is connected to the cylinder 4 of the wave-damping structure by expansion bolts or welding, ensuring a firm and reliable connection, improving the overall structural strength and stability, and enabling the cable guide body 1 to effectively resist vibration and impact loads in the marine environment, thereby further improving the anti-displacement and anti-vibration effects.
[0038] See Figure 5 and Figure 7In one embodiment, the limiting cover 2 is provided with a first sealing plate 21, a second sealing plate 22, and a connecting portion 23. The first sealing plate 21 closes the corresponding positioning groove 12. The first sealing plate 21 has connecting portions 23 on both sides along the width direction of the cable guide body 1. The connecting portions 23 are connected to the wave-damping structure. The second sealing plate 22 is connected to the first sealing plate 21 and closes the connecting channel. The second sealing plate 22 has a cable guide hole 11. Thus, through the combined design of the first sealing plate 21, the second sealing plate 22, and the connecting portion 23, the positioning groove 12 and the connecting channel are effectively closed. At the same time, the connecting portion 23 is stably connected to the wave-damping structure, forming a multiple constraint mechanism. This ensures the axial limiting accuracy of the cable 5 while enhancing the vibration resistance and environmental adaptability of the overall structure.
[0039] In one embodiment, the connecting part 23 is connected to the cylinder 4 of the wave-damping structure by a second fastening screw or a second fastening bolt, ensuring a firm and reliable connection and improving the overall structural strength and stability.
[0040] In one embodiment, the limiting cover 2 is made of hard rubber. Using hard rubber to make the limiting cover 2 provides sufficient structural rigidity to ensure the limiting effect, while also possessing elastic buffering characteristics to absorb vibration energy. This avoids wear on the surface of the cable 5, achieving a balance between reliable protection and flexible constraint. Furthermore, the limiting cover 5 reliably seals the positioning groove 11 and the connecting channel, preventing mud and sand from entering the cable guide hole 11.
[0041] In one embodiment, the cable guide body 1 is provided with a lead rope (not shown in the figure), which passes through the cable guide hole 11. The lead rope is used to guide the cable 5 through the cable guide hole 11, which facilitates the cable 5 to be inserted and improves the installation efficiency of the cable 5.
[0042] In one embodiment, the lead rope is made of 316 stainless steel. The use of 316 stainless steel to make the lead rope gives it excellent resistance to seawater corrosion and higher mechanical strength, making it particularly suitable for long-term use in marine environments. It can effectively resist seawater erosion and maintain structural stability.
[0043] The anti-vibration cable guide device of this utility model has the following advantages: Improved vibration suppression performance: The straight cable body 1 eliminates bending stress, and with the rigid end limit (i.e., the limit cover plate 2), the radial / axial displacement amplitude of the cable 5 is reduced by ≥70% (compared to the measured data of the bent cable tube), significantly reducing the risk of friction damage.
[0044] Structural stability enhancement: Welding and fixing during the prefabrication stage and the installation of connecting parts 3 at intervals increase the bending stiffness of the cable guide body 1 by more than 3 times (based on finite element analysis), effectively resisting wind and wave deformation.
[0045] Damage control during installation: Pre-installed lead ropes and 10kN cable pulling force control to avoid tensile damage to the cable during installation.
[0046] Dynamic sealing protection: The limit cover 2, made of rubber material, is designed to achieve a mud and sand blocking efficiency of >99% (ISO2810 standard test).
[0047] Enhanced system robustness: The synergy with armored cable 5 and underwater burial measures reduces the signal interruption rate under typhoon conditions to 1 / 5 of the traditional solution (statistics from marine trials).
[0048] A preferred embodiment of this utility model provides a bottom-mounted observation system, including the aforementioned anti-shake cable device.
[0049] The bottom-mounted observation system of this utility model, by employing the aforementioned anti-vibration cable guide device, also achieves full axial limitation and radial constraint of the underwater acoustic Doppler current profiler data cable 5 through the coordinated cooperation of the cable guide body 1 and the limiting cover plate 2, effectively suppressing displacement caused by environmental loads and preventing cable 5 vibration. The cable guide body 1 is provided with a cable guide hole 11 for the cable 5 to pass through, providing full axial protection and limitation functions. The limiting cover plate 2 and the positioning groove 12 are designed to close the positioning groove 12 and the end opening between the positioning groove 12 and the cable guide hole 11. The connection channel allows the two ends of the limiting cover plate 2 to connect with the wave-damping structure, enhancing the overall structure and improving the constraint stability of the cable 5, thus improving the anti-displacement and anti-vibration effects. At the same time, the limiting hole 221 of the limiting cover plate 2 is adapted to the cable 5 and allows the cable 5 to pass through the cable guide body 1. By axially limiting and radially constraining the two ends of the cable 5, the cable 5 is reliably fixed to the cable guide body 1, avoiding friction or squeezing between the cable 5 and the edge of the wave-damping structure due to environmental load, preventing damage to the cable 5 sheath and breakage of the internal cable, and ensuring that the cable 5 can work stably and continuously in complex environments.
