Underwater zero-buoyancy cable winding drum

Abstract

The invention belongs to the field of ocean underwater transmission, and particularly relates to an underwater zero-buoyancy cable winding drum. The underwater zero-buoyancy cable winding drum 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, in 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 an underwater platform respectively through bearings, the rolling bearings are arranged at the two ends of the rotating shaft in a penetrating mode, and the rolling bearings are arranged in the bearing pedestals and sealed by bearing inner sealing covers and bearing outer sealing covers. A key groove is reserved in one end of the rotating shaft, and therefore the rotating shaft can be conveniently connected with a driving motor or speed reduction mechanism. According to the underwater zero-buoyancy cable winding drum, adjustment is carried out by means of buoyancy of the center penetrating floating ball, the center penetrating floating ball is in the zero-buoyancy state underwater, and underwater driving of the drum is facilitated; the center penetrating floating ball is arranged at the position, arranged on the rotating shaft, in the coiling block, the interior of the coiling block can be opened, the rotating shaft, the coiling block, the rolling bearings and the like are all in movable connection, and therefore the center penetrating floating ball can be conveniently replaced.

Description

technical field [0001] The invention belongs to the field of marine underwater transmission, in particular to an underwater zero-buoyancy cable winding drum. Background technique [0002] Detection devices such as underwater winches are widely used in marine scientific research, applied oceanography and marine resources survey and exploration, and the most important component is the drum. The drum is used for winding the cable, and it is hoped that it can be driven as easily as possible, and it is especially hoped that a smaller driving force can be used to start the system. The cable drum of the existing underwater winch is relatively difficult to drive, and requires a large driving force to start; and the existing drum is large in size, which sometimes affects the winding of the cable. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an underwater zero-buoyancy cable winding drum. The drum satisfies the requirement that it can be sta...
