[0016] 2. When the ship shakes during the working process of the fairlead, in order to prevent the cable from detaching from the fairlead, the fairlead will be driven to move up and down when it is under pressure. During the movement of the fairlead, the third connecting plate is driven to move up and down for buffering, and then the two groups of sliding rectangular blocks are driven to slide in the slideway. During the sliding process, the two groups of sliding rectangular blocks respectively pull and squeeze one group of the first compression springs to form a buffer for the shaking. Then, when the ship becomes stable, the rebound force of the two groups of first compression springs is used to reset the ship, thereby improving the buffering auxiliary effect of the device.

In the subsequent cable collection process, the cable and the second extrusion head structure are squeezed, driving the cleaning solution in the liquid storage box to be evenly applied to the outer wall of the cable, cleaning it and performing subsequent anti-oxidation protection, thereby extending the service life of the device.

[0018] 4. When the cable shakes, the liquid storage box starts to squeeze the third compression spring. When the third compression spring senses the pressure, it starts to rebound, which provides buffering protection for the shaking cable. In addition, cables of different widths can be limited subsequently, which improves the structural compatibility and the auxiliary limiting effect of the device. The first motor is started to drive the cable guide tube to guide the cable. The second disc drives several groups of sliding tubes to slide in the annular groove while rotating, which improves the structural stability and the protection effect of the motor output end.

A group of first motors 211 are installed on one side wall of the disk 210, and a group of second disks 213 are drivingly connected to the output end of each group of the first motors 211. A plurality of sliding tubes 214 are installed in a circular array on the edge of a side wall of each group of the second disks 213 close to the first disk 210, and each group of the sliding tubes 214 are slidably connected in the annular groove 212. A group of third disks 215 are installed on one side wall of each group of the second disks 213, and a cable guide 216 is connected between the two groups of the third disks 215. One end of a plurality of second compression springs 217 are installed in a circular array on the edge of a side wall corresponding to each group of the third disks 215. The second compression springs 217 are installed in a circular array. A sleeve ring 218 is installed on the other end of the spring 217, and the inner wall of each group of the sleeve rings 218 is movably sleeved on the outer wall of the cable guide 216, and each group of the sleeve rings 218 is provided with a plurality of cavities 219 in a circular array, and a plurality of liquid storage tubes 220 are installed in a circular array on one side wall corresponding to the two groups of the third disks 215, and the outer wall of each group of the liquid storage tubes 220 is slidably connected in the cavity 219, and each group of the liquid storage tubes 220 is connected to a group of first extrusion head structures 221, and a plurality of support frames 222 are installed in a circular array on one side wall corresponding to the two groups of the third disks 215, and a group of pressure sensors 223 are installed on each group of the support frames 222.

[0027] The first motor 211 is started, and the first motor 211 drives the second disc 213 to rotate. The second disc 213 drives the cable guide tube 216 to guide the cable while rotating. The second disc 213 drives several groups of sliding tubes 214 to slide in the annular groove 212 while rotating, thereby improving the structural stability and the protection effect of the motor output end.

[0028] When the ship shakes during the operation of the fairlead, in order to prevent the cable from escaping from the fairlead 216, the fairlead 216 will be driven to move up and down when it is subjected to pressure. During the movement of the fairlead 216, the third connecting plate 209 is driven to move up and down for buffering, and then the two groups of sliding rectangular blocks 208 are driven to slide in the slideway 203. During the sliding process, the two groups of sliding rectangular blocks 208 respectively pull and squeeze one group of the first compression springs 207 to form a buffer for the shaking. Subsequently, when the ship becomes stable, the rebound force of the two groups of first compression springs 207 is used to reset the ship, thereby improving the buffering auxiliary effect of the device.

[0029] When the ship shakes during the cable guiding process, the cable will start to squeeze the sleeve ring 218. The sleeve ring 218 starts to squeeze the second compression spring 217 while sliding on the cable guide tube 216, and also starts to squeeze the pressure sensor 223. The pressure sensor 223 starts to alarm when it is hit. At this time, due to the sliding of the sleeve ring 218, the first extrusion head structure 221 passes through the cavity 219 and is squeezed with the cable. During the squeezing process, a lubricating solution is sprayed out to protect the cable. Autonomous squeezing improves the solution saving effect. The angle of cable deviation is judged by the value of the pressure sensor 223, which improves the cable protection range and the working effect of the cable guide.

[0030] For example, Figure 7 , Figure 8 and Fig. 9As shown, the cleaning component 3 includes a limit frame 301, the bottom of the limit frame 301 is installed on the top of the two groups of second fixed plates 201, a sliding cavity 303 is opened on the bottom of the limit frame 301, two groups of threaded rods 302 are rotatably connected in the sliding cavity 303, a partition plate is connected between the two groups of the threaded rods 302, the thread directions of the two groups of the threaded rods 302 are opposite, and the central axes are located on the same straight line, each group of the threaded rods 302 is threadedly connected to a group of sliding blocks 304, each group of the sliding blocks 304 is slidably connected in the sliding cavity 303, and a group of rectangular blocks 305 are installed on the bottom of each group of the sliding blocks 304, a second motor 306 is installed on the inner wall of one side of the limit frame 301, and the output end of the second motor 306 is transmission-connected to one of the groups of threaded rods 302, and a group of connecting rods 307 are installed on the bottom of each group of the rectangular blocks 305. A group of fan ring structures 308 are installed on one side wall of the connecting rod 307, and a number of groups of fourth connecting plates 309 are evenly spaced on each group of the fan ring structures 308. A group of rotating rods 310 are rotatably connected to each group of the fourth connecting plates 309. A group of fifth connecting plates 311 are installed on one side wall of each group of the rotating rods 310. A group of sleeve tubes 312 are installed on one side wall of each group of the fifth connecting plates 311. A group of sliding rods 313 are slidably connected in each group of the sleeve tubes 312. A group of liquid storage boxes 314 are installed on one side wall of each group of the sliding rods 313. A group of second extrusion head structures 315 are connected to one side wall of each group of the liquid storage boxes 314. One end of two groups of third compression springs 316 are symmetrically installed on one side wall of each group of the fifth connecting plates 311, and the other end of each group of the third compression springs 316 is installed on one side wall of the liquid storage box 314.

[0031] After the device is placed at a designated location, the installation plate 102 is started to install the device, and then the ship's cable is passed through the auxiliary ring 104 and wound around the fairlead 216 .

[0032] The cable is located between the two sets of fan ring structures 308, and then the second motor 306 is started to drive the threaded rod 302 to rotate. While the threaded rod 302 rotates, it drives the two sets of sliding blocks 304 to slide towards each other in the sliding cavity 303, so that the two sets of fan ring structures 308 are fitted together, and the output ends of several sets of second extrusion head structures 315 are driven to contact the outer wall of the cable. In the subsequent cable winding process, the cable and the second extrusion head structure 315 are squeezed, and the cleaning solution in the liquid storage box 314 is evenly applied to the outer wall of the cable to clean it and provide subsequent anti-oxidation protection, thereby extending the service life of the device. When the cable shakes, the liquid storage box 314 is driven to start squeezing the third compression spring 316. When the third compression spring 316 senses the pressure, it starts to rebound, which has the effect of buffering and protecting the shaking cable, and can subsequently limit cables of different widths, thereby improving the structural compatibility effect and the auxiliary limiting effect of the device.

[0033] While the sleeve ring 218 slides on the cable guide tube 216, it starts to squeeze the second compression spring 217 and starts to squeeze the pressure sensor 223. The pressure sensor 223 starts to sound an alarm when it is hit. At this time, the sliding of the sleeve ring 218 causes the first extrusion head structure 221 to be squeezed against the cable. During the squeezing process, a lubricating solution is sprayed out to protect the cable. The autonomous squeezing improves the solution saving effect. The angle of cable deviation is judged by the value of the pressure sensor 223, which improves the cable protection range and the working effect of the cable guide.

[0034] When the ship shakes during the operation of the fairlead, in order to prevent the cable from escaping from the fairlead 216, the fairlead 216 will be driven to move up and down when it is subjected to pressure. During the movement of the fairlead 216, the third connecting plate 209 is driven to move up and down for buffering, and then the two groups of sliding rectangular blocks 208 are driven to slide in the slideway 203. During the sliding process, the two groups of sliding rectangular blocks 208 respectively pull and squeeze one group of the first compression springs 207 to form a buffer for the shaking. Subsequently, when the ship becomes stable, the rebound force of the two groups of first compression springs 207 is used to reset the ship, thereby improving the buffering auxiliary effect of the device.

[0035] The cable is located between the two sets of fan ring structures 308, and then the second motor 306 is started to drive the threaded rod 302 to rotate. While the threaded rod 302 rotates, it drives the two sets of sliding blocks 304 to slide towards each other in the sliding cavity 303, so that the two sets of fan ring structures 308 are fitted together, and the output ends of several sets of second extrusion head structures 315 are driven to contact the outer wall of the cable. In the subsequent cable winding process, the cable and the second extrusion head structure 315 are squeezed, and the cleaning solution in the liquid storage box 314 is evenly applied to the outer wall of the cable to clean it and provide subsequent anti-oxidation protection, thereby extending the service life of the device.

[0036] When the cable shakes, the liquid storage box 314 starts to squeeze the third compression spring 316. When the third compression spring 316 feels the pressure, it starts to rebound, which provides buffering and protection for the shaking cable. In addition, cables of different widths can be limited subsequently, which improves the structural compatibility and the auxiliary limiting effect of the device. The first motor 211 is started to drive the cable guide tube 216 to guide the cable. The second disc 213 drives several groups of sliding tubes 214 to slide in the annular groove 212 while rotating, which improves the structural stability and the protection effect of the motor output end.

Exemplarily, the cable guiding method includes: Activating the auxiliary component to wind the cable; Start the cleaning component to limit the position; The cable compresses the sleeve ring, and the sleeve ring compresses the second compression spring; Then squeeze the pressure sensor, and it will start to sound an alarm when it is hit; The first extrusion head structure sprays a lubricating solution to protect the cable; The angle of cable deviation is determined by the value of the pressure sensor.
