DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 13 The present invention provides a technical solution: a low-friction cable guide sleeve, comprising a first guide sleeve 1 and a second guide sleeve 2, the first guide sleeve 1 and the second guide sleeve 2 are assembled by a mortise and tenon structure, and a first connecting hole 3 is provided on the first guide sleeve 1, and a second connecting hole 4 is provided on the second guide sleeve 2, the first guide sleeve 1 and the second guide sleeve 2 are fastened and connected by fasteners passing through the first connecting hole 3 and the second connecting hole 4, the first guide sleeve 1 and the second guide sleeve 2 are both provided with lifting holes 5, and the edges of the first guide sleeve 1 and the second guide sleeve 2 are both provided with chamfers.

[0035] The low-friction fairlead sleeve of the present invention adopts a split structure, which is convenient for later maintenance. It is composed of a first guide sleeve 1 and a second guide sleeve 2. The two are first preliminarily engaged through a mortise and tenon structure, and then the fasteners pass through the first connecting hole 3 and the second connecting hole 4 to complete the fixation of the two. The combined fairlead sleeve is installed on the ship through the lifting hole 5. The installation process is simple and reliable. The cable can pass through the fairlead sleeve to complete the mooring work. The first guide sleeve 1, the second guide sleeve 2, and the fasteners are all made of aviation materials with high corrosion resistance and tightness. All positions that may contact the cable are chamfered to minimize the risk of possible cable wear, effectively ensuring the safety of mooring and increasing the service life of the fairlead sleeve and the cable.

[0036] A cable health monitoring system matched with a low-friction cable guide sleeve comprises a monitoring device and an analysis system.

[0037] The cable guide sleeve of the present invention is also equipped with a corresponding health monitoring system, which can perform health monitoring of the cable. The cable used in the mooring system usually adopts a 3-strand or 8-strand structure. During monitoring, the system can perform corresponding risk prediction and early warning according to the number of broken strands.

[0038] The monitoring device includes a monitoring seat 6, and the monitoring seat 6 is installed on the cable guide sleeve, a sliding seat 10 is rotatably arranged on the monitoring seat 6, and a base 11 is fixedly installed on the sliding seat 10, a bracket 12 is fixedly connected to the base 11, and a control seat 13 is fixedly installed on the bracket 12, and a visual monitor 14 and an acoustic monitor 15 are connected to the control seat 13, and the visual monitor 14 and the acoustic monitor 15 are arranged in the direction of the cable guide sleeve, an outer tooth 9 is arranged around the outer wall of the monitoring seat 6, and a pop-up positioning device is movably installed on the base 11. The base 11 is connected to the outer teeth 9 through the positioning structure for positioning. A cross bar 21 is movably installed on the side wall of the base 11, and the cross bar 21 can retract the positioning structure when it moves. An elastic air bag 24 is fixedly installed in the bracket 12, and an air pipe 25 is connected to the elastic air bag 24. The air pipe 25 is connected to an air jet slot 26 arranged toward the visual monitor 14 and the acoustic monitor 15. When the cross bar 21 moves, the elastic air bag 24 can be compressed to achieve the effect of jetting from the air jet slot 26.

[0039] The health monitoring system is divided into two parts: hardware and software. The hardware part is the monitoring device, and the software part is the analysis system. The monitoring device is mainly carried out through visual monitoring and acoustic monitoring.

[0040] The monitoring seat 6 is provided with an assembly hole 7, and the monitoring seat 6 is installed on the cable guide sleeve by docking the assembly hole 7 with the lifting hole 5. The monitoring seat 6 is provided with a guide groove 8 with the same shape as the edge of the cable guide sleeve, and the slide seat 10 is connected in the guide groove 8.

[0041] The monitoring device uses a monitoring seat 6 as a basic component. An assembly hole 7 is provided on the monitoring seat 6, which can be aligned with the lifting hole 5 on the first guide sleeve 1 or the second guide sleeve 2, and is fixed by screws and other components, so that the monitoring seat 6 is located on one side of the cable guide sleeve, and the cable can also pass through the monitoring seat 6. The slide seat 10 is installed on the monitoring seat 6 through the guide groove 8, and the slide seat 10 can change its position on the monitoring seat 6 to avoid obstruction to the movement of the cable.

[0042] The base 11 is an L-shaped structure, and a limit foot 19 is fixedly installed on the base 11, and the limit foot 19 is movably connected to the outer wall of the monitoring seat 6. The bracket 12 is an L-shaped structure, and the visual monitor 14 and the acoustic monitor 15 are installed at the end of the bracket 12.

[0043] The base 11 is further installed through the slide 10. The limit foot 19 set on the base 11 is connected to the outside of the monitoring seat 6, and cooperates with the slide 10 to ensure the stability of the base 11. The monitor is hoisted on the base 11 through the bracket 12 and the control seat 13. The monitor is divided into a visual monitor 14 and an acoustic monitor 15. It is set toward the cable in the guide cable sleeve. The visual monitor 14 relies on a camera and an image processing algorithm. The camera captures the state of the cable in real time. The captured image will be transmitted to a computer or processing unit and analyzed by an image processing algorithm, including edge detection, shape recognition and color analysis, etc., which can judge the integrity, degree of wear and fracture state of the cable. The algorithm extracts key features, such as the diameter change, wear marks and fracture points of the cable, and then compares these data with the preset safety standards. The acoustic monitor 15 relies on a sound sensor and a signal processing algorithm. The acoustic sensor can capture the sound generated by the cable when it is stressed or moving in real time. The captured sound signal will be transmitted to the signal processing unit for digitization and analysis. The steps of signal processing include noise reduction, signal amplification and feature extraction. Through technologies such as Fast Fourier Transform (FFT), the sound signal is converted into a spectrum to identify the frequency components and patterns therein. Conditions such as cable breakage and wear will produce specific sound spectrum characteristics. Using machine learning algorithms, the system can learn and identify audio features associated with normal working conditions and abnormal conditions, thereby realizing the monitoring of cable status.

[0044] The positioning structure includes a translation seat 16 movably mounted in the base 11, and a positioning member 17 and an elastic member 18 are fixedly connected to the translation seat 16, the positioning member 17 is arranged through the base 11, and the elastic member 18 is connected to the base 11. The edge of the monitoring seat 6 is provided with a chamfer, and a cross bar 21 is located above the edge of the monitoring seat 6, the cross bar 21 is arranged through both sides of the base 11, and a triangular side angle block 22 is installed on the side of the cross bar 21, and two L-shaped push members 20 are symmetrically connected to the translation seat 16, and the push members 20 are in contact with the inclined surfaces of the side angle blocks 22.

[0045] After the cable passes through the monitoring seat 6, it is usually straightened to the side, so that it is tightly attached to the edge chamfer of the monitoring seat 6, and as the ship moves, the cable will also change direction. Therefore, the base 11 and the monitor are set to a movable structure. When the cable pushes the base 11, the base 11 can move accordingly. When the position of the cable is temporarily fixed, the base 11 can be fixed by the positioning structure. The elastic force of the elastic member 18 acts on the translation seat 16, and the positioning member 17 thereon pops out and can be connected with the outer teeth 9 on the monitoring seat 6, thereby ensuring the stability of the base 11, the bracket 12 and the monitor. When the cable needs to move, it will stick to the side of the base 11, exerting pressure on the cross bar 21 to move it, and the side angle block 22 on the cross bar 21 will move accordingly, and the pushed member 20 can be pushed inward through the inclined surface, so that the translation seat 16 drives the positioning member 17 to retract and disengage from the outer teeth 9. Therefore, the base 11 can rotate with the cable without affecting the normal operation of the cable.

[0046] A triangular corner block 23 is fixedly mounted on the top surface of the crossbar 21, and a moving rod 27 is slidably mounted in the bracket 12. A weight ball 28 is mounted on one end of the moving rod 27, and a rack 29 is mounted on the other end. The weight ball 28 is movably connected to the inclined surface of the corner block 23. A rotating shaft 30 is rotatably mounted in the bracket 12, and a gear 31 and a pressure plate 32 are coaxially connected to the rotating shaft 30. The gear 31 is meshed with the rack 29, and the pressure plate 32 can compress the elastic airbag 24 when rotating. The air pipe 25 is arranged in the bracket 12.

[0047] Taking into account that the debris generated by the friction of the cable may have an adverse effect on the camera and microphone of the monitor, the present invention is also provided with an injection structure for the two monitors. When the cross bar 21 is pushed by the cable, the top corner block 23 thereon can move accordingly, and its position change will cause the counterweight ball 28 to rise and fall. When the counterweight ball 28 drives the moving rod 27 to move, the rack 29 can drive the gear 31 and the rotating shaft 30 to rotate, and the pressure plate 32 on the rotating shaft 30 can rotate accordingly, compressing the elastic airbag 24, and sending the gas from the air pipe 25 into the injection slot 26, which then acts on the two monitors to blow away the debris of the cable and external dust, thereby ensuring the normal operation of the monitors.

[0048] The analysis system includes data acquisition module, signal processing module, health status assessment module, fault diagnosis module, data storage and management module, and early warning and notification module;

[0049] Data acquisition module: Receives real-time data from monitoring devices (visual monitor 14 and acoustic monitor 15). Ensures data accuracy and integrity, and can perform data preprocessing, such as noise filtering, removal of redundant information, etc.

[0050] Signal processing module: Analyze and process the collected acoustic and visual signals. Through the signal feature extraction algorithm, extract key signal features (such as vibration frequency, amplitude, image features, etc.) for subsequent analysis.

[0051] Health status assessment module: Evaluate the health status of the fairlead and cable based on the extracted features. Use models and algorithms (such as machine learning algorithms) to compare historical data to identify potential abnormal conditions, such as wear, fatigue, and breakage risks.

[0052] Fault diagnosis module: Identify and diagnose possible fault types based on the results of health status assessment. Provide fault severity classification and generate corresponding recommended measures. For example, when monitoring a 3-strand cable, 1 strand break is a low risk threshold, 2 strand break is a high risk threshold. When monitoring an 8-strand cable, 2 strand break is a low risk threshold, 4 strand break is a medium risk threshold, and 6 strand break is a high risk threshold.

[0053] Data storage and management module: Stores historical monitoring data and analysis results for subsequent query and analysis, ensuring data security and reliability.

[0054] Early warning and notification module: Provides real-time alert function when abnormalities or potential failures are detected, notifying relevant personnel so that necessary measures can be taken. It can be combined with mobile applications or SMS notifications to enhance response speed.

[0055] Through the collaborative work of the above modules, the monitoring system can provide efficient cable monitoring and analysis functions, thereby improving the safety and reliability of the ship.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
