Underwater zero buoyancy cable winding drum

Abstract

The invention belongs to the field of marine underwater transmission, in particular to an underwater zero-buoyancy cable winding drum, which includes a rotating shaft, a bearing seat, a drum and a center-through floating ball, wherein the rotating shaft passes through the drum and is connected to the drum. The center-through floating ball is located in the reel and is set on the rotating shaft inside the reel; the two ends of the rotating shaft are respectively connected to the bearing seat installed on the underwater platform through bearings; the two ends of the rotating shaft are worn with Rolling bearings, rolling bearings are located in bearing housings and are sealed by bearing inner and outer covers. There is a keyway at one end of the rotating shaft, which is convenient for connecting the drive motor or the reduction mechanism. The present invention relies on the buoyancy adjustment of the center-through floating ball, and is in a state of zero buoyancy underwater, which is beneficial to the underwater driving of the drum; the center-through floating ball of the present invention is located on the rotating shaft in the drum, and the inside of the drum can be opened, and the rotating shaft It is connected with the reel and the rolling bearing, etc., and the through-center float can be easily 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 resource investigation and exploration, and the important component device is the drum. The drum is used to wind the cable, and it is hoped that it can be driven as easily as possible, and it is especially hoped that a small 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; moreover, the existing drum has a large volume, which sometimes affects the winding of the cable. Contents of the invention

[0003] The object of the present invention is to provide an underwater zero-buoyancy cable winding drum. The drum satisfies the requirement that it ...

Examples

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] like figure 1 As shown, the present invention includes a fixed base 2, a rotating shaft 5, a bearing seat 6, a reel 7, a through-center floating ball 8 and a rolling bearing 12. Located in the reel 7 and sleeved on the rotating shaft 5 inside the reel 7; The two ends of the rotating shaft 5 are rotationally connected with the bearing seat 6 through the rolling bearing 12 respectively, the rolling bearing 12 is located in the bearing seat 6, and is sealed by the inner and outer covers of the bearing; the two bearing seats 6 are respectively fixed on two fixed bases 2, And these two fixed bases 2 are respectively fixed on the underwater platform. The present invention relies on the buoyancy adjustment of the center-piercing floating ball 8, and is in a state of zero buoyancy underwater.

[0025] like Figure 6-8 As shown, the reel 7 includes a left s...
