underwater cable retractor

Abstract

The invention belongs to the field of marine underwater transmission, and specifically relates to an underwater cable retractor, which includes a pressure roller device and a zero-buoyancy winding drum, and the zero-buoyancy winding drum is installed on an underwater platform, including a rotating shaft, a bearing seat, The reel and the through-center floating ball, the rotating shaft passes through the reel and is linked with the reel, the through-center floating ball is located in the reel and is sleeved on the rotating shaft inside the reel; the two ends of the rotating shaft are respectively installed with the underwater The bearing seat on the platform is connected in rotation; the pressure roller device is located between the two disks of the reel of the zero-buoyancy winding drum, and is located on the periphery of the cylinder around which the reel is wound with cables, and the cable is located between the pressure roller device and the zero-buoyancy winding drum between cylinders. The present invention can make the entire zero-buoyancy winding drum in a zero-buoyancy state under water by selecting center-through floating balls of different diameters, which minimizes the driving force required for system startup and is easy to drive; During the process, through the function of the pressure roller device, the cable is always guaranteed to run in place.

Description

technical field [0001] The invention belongs to the field of marine underwater transmission, in particular to an underwater cable retractor. Background technique [0002] In marine observation, applied oceanography and marine resources investigation and exploration, underwater cable winding is often required. For example, underwater cable retraction and detection devices based on underwater winches have a wide range of uses. It is hoped that the drum used for winding the cable can be driven as easily as possible, and it is especially hoped that the drum can be started with a small driving force for cable retraction. On the other hand, due to effects such as the current in the ocean, the cable often runs away from the drum, that is, deviates from the originally designed track, which affects the winding of the cable on the underwater winch drum. In order to ensure that the cable runs in place, sometimes it is necessary to limit the running track; at the same time, this kind o...

Problems solved by technology

However, the existing cable-wound drum is difficult to drive underwater and needs a large driving force to start; moreover, the limit device of the existing cable requires additional energy supply, which affects the use of the device.
