Underwater neutral cable arranging mechanism with movable winding drum

Abstract

An underwater neutral cable arranging mechanism with a movable winding drum comprises two opposite horizontally moving carriages and the winding drum installed between the two horizontally moving carriages. A guide rail is arranged on the upper portions of the horizontally moving carriages. A cable arranging mechanism body is installed between the two horizontally moving carriages and located below the winding drum. The horizontally moving carriages on the two sides are respectively provided with a set of chain wheel transmission mechanism. One set of chain wheel transmission mechanism drives the winding drum to rotate, and the other set of chain wheel transmission mechanism drives the cable arranging mechanism body to rotate. A tail mandrel on a nut swing link in the cable arranging mechanism body is embedded in a radial cylindrical hole of a fixed sliding block. The fixed sliding block is fixedly connected with a repeater rack. Due to action of thread screwing between a bidirectional screw and the nut swing link, the nut swing link swings around the axis of the nut swing link when reversing of the ends of the bidirectional screw is performed, and then the horizontally moving carriages are driven to move. The winding drum not only can rotate around the axis of the winding drum, but also can move forth and back along the axis of a carriage horizontally moving mechanism, and the cable arranging quality is improved.

Description

technical field [0001] The invention relates to a cable-discharging mechanism, in particular to an underwater reel movable neutral cable-discharging mechanism for deploying / recovering a single-person atmospheric-pressure diving outfit or other remote-controlled submersibles. Background technique [0002] The single-person atmospheric diving suit (ADS) is a humanoid underwater operation device. The device has good manoeuvrability and strong maneuverability. Its advantage is that the body is small and light, can enter some specific areas, and can complete some complicated underwater operations that only divers could complete before. It is deployed / recovered by special lifting equipment, equipped with photography, video equipment and lighting. The outside of this submersible can withstand the pressure of the operating water depth, while the inside maintains an atmospheric pressure; therefore, divers do not have to undergo the process of descending to pressurize and ascending t...

AI Technical Summary

Problems solved by technology

Therefore, in the swing type cable arrangement mechanism, the neutral cable will be twisted and bent back and forth during the cable arrangement process, which will affect the service life of the neutral cable and the quality of the cable arrangement;

[0010] (2) Since the two-way screw in the swing-type cable arrangement drives the slider to move linearly along its axis through the nut crescent plate (or shift block, active ring, sliding tongue), at the same time, the slider is fixed on its The roller-chute motion pair on the top makes the swing frame swing around its axis. When the swing frame swings from the middle position of the drum to the two ends of the drum, because the top track of the swing frame is a circular arc, and the cable discharge joint of the drum It is parallel to the chord line corresponding to its arc, so the pitch of the cable arrangement will gradually become smaller, so there is a certain error in the cable arrangement, which reduces the accuracy of the cable arrangement;

[0011] (3) In order to reduce the cable discharge error of the swing type cable discharge mechanism, the swing angle of the swing frame must be as small as possible. In this way, the rotation radius of the swing frame must be increased, and finally the height of the cable discharge mechanism increases. It is not conducive to the arrangement and installation on the repeater of the single-man atmospheric diving suit (ADS);

[0012] (4) Since the neutral cable swings in the space with the swing frame during the cable discharge and transportation process, the neutral cable is finally fixed along the rotation axis of the swing frame, and the position of the cable outlet depends on The position of the rotation axis of the pendulum frame, so that the adjustment range of the position of the neutral cable outlet is small, which is not conducive to docking with the engaging device of the single-person atmospheric diving suit (ADS) below;

[0013] (5) The structure of the swing-type cable arrangement and conveying mechanism is relatively complex, and the installation requirements of the swing frame shaft are high, and the rigidity of the installation frame is required to be good
