[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] A cable pressing device for underwater winch traction, such as Figures 1-8 As shown, it includes a mounting base 1, a moving block 2, a driving assembly 3, and several groups of cable pressing assemblies 4. The cable pressing assemblies 4 are arranged on the mounting base 1 and press the towline cable onto the cable pulling mechanism through the cable pressing assemblies. The cable pressing assembly 4 includes a pressure rod 41, a spring 42, a floating bracket 43, and a pressure wheel 44. The pressure rod 41 is slidably mounted on the mounting base 1, the floating bracket 43 is mounted at the lower end of the pressure rod 41, the pressure wheel 44 is mounted on the floating bracket 43, and the spring 42 is sleeved on the pressure rod 41. The two ends of the spring 42 act on the mounting base 1 and the pressure rod 41 respectively. The spring 42 provides downward pressure to the pressure rod 41 and transmits it to the floating bracket 43, so that the pressure wheel 44 presses the towline cable. The moving block 2 is slidingly set on the mounting base 1, and the driving component 3 is connected to the moving block 2. The driving component 3 drives the moving block 2 to move back and forth along the arrangement direction of the cable pressing component. A lifting part 21 is set on the moving block 2, and the lifting part 21 is driven by the moving block 2 to move synchronously. The lifting part 21 acts on the floating bracket 43, and then the lifting part 21 pushes the pressing wheel 44 up and down to adjust the height position of the pressing wheel 44.

[0027] In one embodiment, if Figures 1-8As shown, the cable compression assembly 4 further includes a sliding sleeve 45, which is disposed on the compression rod 41. The mounting base 1 is provided with a guide hole, and the sliding sleeve 45 is slidably disposed in the guide hole. By disposing the sliding sleeve 45, the sliding sleeve 45 and the guide hole slide together, avoiding direct contact between the compression rod 41 and the guide hole, thereby reducing wear on the compression rod 41.

[0028] In the above embodiment, if Figures 1-8 As shown, the pressure rod 41 is provided with a first connecting hole 411 along its axial direction, and the sliding sleeve 45 is provided with a second connecting hole 451. The second connecting hole 451 is connected to the corresponding first connecting hole 411 through a latch 46, so as to realize a quick connection between the sliding sleeve 45 and the pressure rod 41.

[0029] In one embodiment, if Figures 1-8 As shown, the lower end of the pressure rod 41 is radially protruded with a limiting edge 412, and the spring 42 acts on the limiting edge 412. The limiting edge 412 plays the role of supporting the spring 42 and facilitates the fixing of the floating bracket 43 to the limiting edge 412.

[0030] In one embodiment, if Figures 1-8 As shown, slideways 11 are provided on both sides of the mounting base 1, and the moving block 2 is in a U-shaped structure. The moving block includes a connecting plate 22 and side plates 23 provided parallel to both sides of the connecting plate 22. The side plates 23 are slidably connected to the slideways 11.

[0031] In a preferred embodiment, if Figures 1-8 As shown, a pressure strip 12 is fixed to the side of the mounting base 1 by bolts, and the pressure strip and the side wall of the mounting base 1 form a slideway 11.

[0032] In one embodiment, if Figures 1-8 As shown, the drive assembly 3 includes a guide rack 31, a drive gear 32, and a servo motor (not shown). A mounting bracket 13 is provided on one end of the mounting base 1. The guide rack 31 is provided on the moving block 2, the servo motor is provided on the mounting bracket 13, and the drive gear 32 is provided on the servo motor. The drive gear 32 is engaged with the guide rack 31. The servo motor drives the drive gear 32 to rotate, thereby driving the guide rack 31 to drive the moving block 2 to move horizontally.

[0033] In the above embodiment, if Figures 1-8 As shown, a guide sleeve 131 is provided on the mounting bracket 13, and one end of the guide rack 31 slides with the guide sleeve 131. Both ends of the guide rack 31 are provided with fulcrums to ensure that the guide rack 31 is engaged with the drive gear 32, and effectively prevent the guide rack 31 from deforming, thereby improving the service life.

[0034] In one embodiment, if Figures 1-8As shown, the pressure roller 44 is mounted on the floating bracket 43 via a mounting shaft 431, with both ends of the mounting shaft 431 protruding from the floating bracket 43. The mounting shaft 431 is provided with a roller 432 that engages with the lifting portion 21. The mounting base 1 is provided with a guide groove 15, and the roller 432 is positioned within the guide groove 15. The roller 432 cooperates with the guide groove 15 to guide the pressure roller 44 in its up and down movement. During use, the roller 432 contacts the lifting portion 21, allowing the floating bracket 43 to move up and down smoothly.

[0035] In one embodiment, if Figures 1-8 As shown, the lifting portion 21 is a wedge-shaped block. The inclined surface of the wedge-shaped block contacts the roller 432, and the pressing wheel 44 is pushed upward by the wedge-shaped block.

[0036] In one embodiment, if Figures 1-8 As shown, a proximity switch 14 is provided on the mounting base 1, and an identification block 24 cooperating with the proximity switch is installed on the moving block 2. The servo motor can precisely control the stroke of the moving block 2 through the absolute zero point, thereby precisely controlling the up and down movement distance of the pressing wheel 44.

[0037] When the utility model is in use; Figures 1-8 As shown, during the initial cable release process, the pressing wheel 44 of the cable pressing device is evenly pressed on the array by the spring 42, so that the array can be released smoothly in the initial state.

[0038] When the towline is released to a length of 40m, the cable pressing device no longer needs to provide cable pressing force. At this time, the servo motor drives the drive gear 32 to make the guide rack 31 move horizontally, thereby pushing the pressure wheel 44 upward through the lifting part 21 to achieve separation from the towline.

[0039] When the array release is completed, the cable diameter sensor feedback indicates that the towline has entered the stage of laying. At this time, the control system controls the servo motor to reverse, and the pressure wheel 44 slowly moves downward from the lifting part 21 and finally separates from the lifting part 21. At this time, under the action of the spring 42, the pressure wheel 44 moves downward as a whole until it is pressed on the towline, ensuring that the towline will not have a large-scale movement in the cable pulling groove of the traction mechanism during the release process.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Without departing from the spirit and scope of the present invention, modifications or equivalent replacements of the present invention should be included in the scope of protection of the claims of the present invention.
