Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0016] Such as figure 1 As shown, this optical fiber microcable retractable winch includes a DC torque motor 2, a reel 1, a tensioning mechanism and a cable arrangement mechanism, the reel 1 is connected to the output shaft of the DC torque motor 2, and the reel 1 is driven by a DC torque Motor 2 drives. In order to better realize the stable control of tension, the optical fiber micro cable winch also has a set of tensioning mechanism. The tensioning mechanism includes a movable pulley 4, a fixed pulley A3 and a fixed pulley B8, the movable pulley 4 is installed on a support 10 with a spring device 5, and the optical fiber micro cable 6 is wound by the fixed pulley A3, the movable pulley 4, and the fixed pulley B8 Attached to reel 1. The movement of the movable pulley 4 changes the active force of the spring device 5 and also changes the length of the cabl...

Abstract

The invention relates to an optical fiber micro cable withdrawing and releasing winch, which comprises a direct current torque motor, a winding drum, a tensioning mechanism and a cable arrangement mechanism, wherein the winding drum is connected with an output shaft of the direct current torque motor; the tensioning mechanism comprises a movable pulley, a fixed pulley A and a fixed pulley B; the movable pulley is arranged on a bracket with a spring device; and the optical fiber micro cable is wound and connected to the winding drum through the fixed pulley A, the movable pulley and the fixed pulley B. The invention has the advantages that: 1) the winch drives the winding drum through the direct current torque motor, the tension control characteristic is improved, the cable tension is directly controlled through a mode of controlling the motor current, and the defect brought by the conventional speed closed-loop control system is overcome; and 2) the tensioning mechanism with length compensation function is arranged in the winch, and the condition of too tight or too loose cable due to instantaneous speed change is prevented.

Description

technical field [0001] The invention relates to a winch for retracting and retracting an optical fiber microcable for an underwater robot, in particular to a winch for retracting and retracting an optical fiber microcable. Background technique [0002] Generally speaking, optical fiber microcables refer to optical cables with a diameter of less than 0.1 inches. Compared with ordinary wires, optical fiber microcables have the advantages of low density, thin diameter, good anti-interference, wide transmission frequency bandwidth, high transmission rate, and low cost. . Realizing the communication between the underwater robot and the mother ship through the optical fiber micro-cable can greatly reduce the size and weight of the retractable system, and reduce the impact of the cable on the carrier's range of motion, motion speed and maneuverability. [0003] However, fiber optic microcables have lower breaking strength due to their smaller diameters. In the process of retracti...
