[0002] The Tether Management System (TMS) is a core component of an underwater winch. Its primary function is to store, brake, and release the underwater winch cable. During deployment, the TMS uses a braking system to control cable tension, ensuring the underwater winch and load maintain a suitable relative position and speed, and meeting deployment requirements at varying sea depths.

[0007] In the above-mentioned dual-redundant magnetic powder brake type cable management device, the traction assembly includes two sets of magnetic powder brake type tension reduction assemblies with the same structure; wherein the two sets of magnetic powder brake type tension reduction assemblies are fixed with bolts and then installed on the frame.

[0008] In the above-mentioned dual-redundant magnetic powder brake type cable management device, the magnetic powder brake type tension reduction assembly includes: a magnetic powder brake, a connecting flange, a tension reduction wheel, an anti-cable jump wheel, a control box and a fixing seat;

[0009] The magnetic powder brake is fixed on the fixing seat through the connecting flange;

[0011] The anti-cable jump wheel and the control box are installed on the fixed seat;

[0012] The magnetic powder brake type tension reducing assembly is fixed to the frame through a fixing seat by bolts.

[0013] In the above-mentioned dual-redundant magnetic powder brake type cable management device, the anti-cable jumping wheel is used to prevent cable jumping.

[0014] In the dual-redundant magnetic powder brake type cable management device, the control box is used to change the torque of the magnetic powder brake by adopting a variable current drive method.

[0015] In the above-mentioned dual-redundant magnetic powder brake type cable management device, the other end of the cable is connected to the load after passing through the tension-reducing wheel and the limit assembly.

[0016] In the above-mentioned dual-redundant magnetic powder brake type cable management device, tension control is achieved by setting the damping force of the traction component to brake the magnetic powder brake, and the potential energy during the load lowering process is converted into thermal energy of the tension-reducing wheel and the magnetic powder brake; the torque of the magnetic powder brake is changed by variable current drive through the control box, and then the tension of the cable at the connection end of the tension-reducing wheel and the load is adjusted, ultimately achieving the purpose of controlling the descent speed and position of the load and the underwater winch.

[0017] In the above-mentioned dual-redundant magnetic powder brake type cable management device, the two sets of magnetic powder brake type tension reduction components serve as backup for each other.

[0019] In the above-mentioned dual-redundant magnetic powder brake type cable management device, the limiting assembly is used to prevent the cable from rubbing against the frame.

[0020] The present invention has the following advantages:

[0021] (1) The present invention discloses a dual-redundant magnetic powder brake type cable management device, which controls the torque of the magnetic powder brake by detecting the cable tension at the output end and the input end of the traction component, so that the cable reaches the set target tension, thereby realizing refined tension control.

[0022] (2) The present invention discloses a dual-redundant magnetic powder brake type cable management device, in which a cable storage assembly and a limit assembly are arranged at both ends of the traction assembly, respectively, to ensure that the cable is released from the cable storage end according to the designed route and connected to the load, thereby avoiding the loosening of the cable during operation.

[0023] (3) The present invention discloses a dual-redundant magnetic powder brake type cable management device, in which the load-end cable first passes through two tension-reducing wheels and is then wound multiple times in a single layer on the two synchronously driven tension-reducing wheels, and the friction between the cable groove and the ultra-high molecular weight polyethylene cable is used as the lifting force of the load; through the tension-reducing effect of the traction component, the tension at the cable outlet of the traction winch will decay rapidly, reducing the initial damping when the underwater winch releases the cable, so that the cable tension between the traction mechanism and the cable storage mechanism is in a small and relatively controllable state.

[0026] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments disclosed in the present invention will be described in further detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 In this embodiment, the dual-redundant magnetic powder brake cable management device includes: a cable storage assembly 1, a traction assembly 2, a position limiting assembly 3, a load 4, a cable 5, and a frame 6. The cable storage assembly 1, traction assembly 2, and position limiting assembly 3 are each mounted and secured by the frame 6. One end of the cable 5 is wound around the cable storage assembly 1, and the other end is connected to the load 4 after passing through the traction assembly 2 and position limiting assembly 3.

[0028] In this embodiment, the cable storage assembly 1 is a reel-type cable storage assembly, which is arranged transversely to ensure that the outgoing end of the cable 5 is subjected to vertical force.

[0029] In this embodiment, the limiting assembly 3 is used to prevent the cable 5 from rubbing against the frame 6 .

[0030] In this embodiment, the traction assembly 2 includes two sets of magnetic powder brake type tension reducing assemblies of the same structure. The two sets of magnetic powder brake type tension reducing assemblies are connected and fixed with bolts and then mounted on the frame 6.

[0031] like Figure 2As shown, the magnetic powder brake tension reduction assembly mainly includes: a magnetic powder brake 7, a connecting flange 8, a tension reduction pulley 9, an anti-cable jump pulley 10, a control box 11, and a fixing base 12. The magnetic powder brake 7 is fixed to the fixing base 12 via the connecting flange 8; the tension reduction pulley 9 and the magnetic powder brake 7 are connected by a shaft key and arranged coaxially; the anti-cable jump pulley 10 and the control box 11 are mounted on the fixing base 12; the anti-cable jump pulley 10 is used to prevent cable jumps; the control box 11 is used to change the torque of the magnetic powder brake 7 using a variable current drive method; the magnetic powder brake tension reduction assembly is bolted to the frame 6 via the fixing base 12; the other end of the cable 5 is connected to the load 4 after passing through the tension reduction pulley 9 and the limit assembly 3.

[0032] In this embodiment, the dual-redundant magnetic powder brake type cable management device can realize tension control by setting the damping force of the traction component 2 to brake the magnetic powder brake 7, and convert the potential energy of the load 4 during the lowering process into thermal energy of the tension reduction wheel 9 and the magnetic powder brake 7; the torque of the magnetic powder brake 7 is changed by variable current drive through the control box 11, and then the tension of the cable at the connection end of the tension reduction wheel 9 and the load 4 is adjusted, and finally the purpose of controlling the descent speed and position of the load 4 and the underwater winch is achieved.

[0033] In this embodiment, the two sets of magnetic powder brake type tension reduction assemblies in the traction assembly 2 serve as backup for each other, that is, if any one of the two sets of magnetic powder brake type tension reduction assemblies fails, the remaining intact magnetic powder brake type tension reduction assembly can ensure that the traction assembly 2 completes the tension reduction function, thereby realizing the normal deployment of the load 4 and the underwater winch, thereby improving the reliability of cable tension control.

[0034] In summary, the present invention discloses a dual-redundant magnetic powder brake type cable management device, which can simplify the system configuration of the cable management device and improve the cable tension control accuracy; when a single redundant magnetic powder brake fails, the remaining intact magnetic powder brake can normally complete the cable tension control action, thereby improving the reliability of cable tension control.
