Underwater cable taking-up and paying-off device

Abstract

The invention belongs to the field of ocean underwater transmission, and particularly relates to an underwater cable taking-up and paying-off device. The underwater cable taking-up and paying-off device comprises a press rolling device and a zero-buoyancy winding drum, the zero-buoyancy winding drum is arranged on an underwater platform and comprises a rotating shaft, bearing pedestals, a coiling block and a center penetrating floating ball, the rotating shaft penetrates through the coiling block and is in linkage with the coiling block, the center penetrating floating ball is arranged in the coiling block, and the position, arranged inside the coiling block, of the rotating shaft is sleeved with the center penetrating floating ball. The two ends of the rotating shaft are rotatably connected with the bearing pedestals arranged on the underwater platform respectively. The press rolling device is arranged between two discs of the coiling block of the zero-buoyancy winding drum and arranged on the periphery of a cylinder, for winding a cable, of the coiling block, and the cable is arranged between the press rolling device and the cylinder of the zero-buoyancy winding drum. According to the underwater cable taking-up and paying-off device, by selecting center penetrating floating balls of different diameters, the whole zero-buoyancy winding drum is in the zero-buoyancy state underwater, driving force required starting of the system is reduced to be greatest extent, and driving is easy. In the process of cable taking-up and paying-off, through the effect of the press rolling device, it is always ensured that the cable runs 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.
