the diameter of the second movable roller 5 is larger than that of the first movable roller 4, the second movable roller 5 and the first movable roller 4 synchronously rotate under the driving of the driving mechanism 6, and the cable passes through the first movable roller 4 and then winds to the second movable roller 5; when the second movable roller 5 rotates, the cable is wound on the second movable roller 5, and when the second movable roller 5 rotates reversely, the cable is wound out of the second movable roller 5.
Wherein, support 1 can set up to an empty box structure, and the outside of support 1 can set up rings, convenient hoist and mount.
The driving mechanism 6 can be a plurality of independent driving mechanisms, which are respectively installed on the first-stage static roller 2, the first movable roller 4, the second movable roller 5 and the central frame 3 to independently drive the first-stage static roller 2, the first movable roller 4, the second movable roller 5 and the central frame 3 to rotate, or can be set as one driving mechanism, which drives the first-stage static roller 2, the first movable roller 4, the second movable roller 5 and the central frame 3 to rotate through transmission parts such as a gear mechanism and a belt wheel mechanism.
Wherein, the first-stage static roller 2 is positioned at the most central position and is fixedly arranged relative to the bracket 1, and the two ends of the first-stage static roller can be fixed on the bracket 1 and can be arranged as a hollow pipe.
The central frame 3 may be in a structure as shown in fig. 2, and is rotatably connected with the first-stage static drum 2, or rotatably connected with the bracket 1, and coaxially rotates with respect to the first-stage static drum 2. The center frame 3 is provided with a guide mechanism 31 for guiding the cable. The guide mechanism 31 may be implemented using rollers.
The working principle of the embodiment is as follows:
the cable that needs to be reeled is wound on the second movable roller 5, one end of the cable is freely reeled, and the other end of the cable passes through one end of the second movable roller 5, then passes through the first movable roller 4 and is wound on the outer surface of the first movable roller 4.

The length of the cable wound on the second movable roller 5 is determined according to the length of the cable to be wound, for example, if the cable needs to be wound for 1000 meters, the length of the cable wound on the second movable roller 5 needs to be wound for at least 1000 meters. When the cables are completely unwound, no cables are on the second movable roller 5, and when the cables are completely furled, all the cables are wound on the second movable roller 5.
When the second movable roller 5 rotates, the cable is necessarily taken up or paid off, that is, the cable is wound on the second movable roller 5, or the cable on the second movable roller 5 is paid off. When the second movable roller 5 rotates, the first movable roller 4 also rotates synchronously, and the rotating speed and the rotating direction are consistent, so that the first movable roller and the second movable roller do not move relatively. At this time, the center frame 3 is also rotating, but the rotation speed of the center frame 3 does not coincide with the rotation speed of the first movable roller 4, and there is a difference in rotation speed, that is, the first movable roller 4 and the center frame 3 have relative movement. This relative movement causes the cable to wind out of, or in, the first movable roller 4. Meanwhile, because the central frame 3 rotates, the cable wound on the first movable roller 4 is wound on the first-stage static roller 2 or wound on the first movable roller 4 from the first-stage static roller 2.
It can be seen that during the rotation of the central frame 3, the first moving roller 4 is passed through the central frame 3 and wound on the first-stage stationary roller 2, and when the central frame 3 rotates in the opposite direction, the first-stage stationary roller 2 is passed through the central frame 3 and wound on the first moving roller 4. While their total cable length is constant and is not affected by the cable length on the second movable drum 5. For example, if the total length is 100 meters, 50 meters are wound on the first movable roller 4, 50 meters are wound on the first-stage stationary roller 2, if 20 meters are wound on the first movable roller 4, 80 meters are wound on the first-stage stationary roller 2, 50 meters are wound on the first movable roller 4, and 30 meters are wound on the first-stage stationary roller 2 when 70 meters are wound on the first movable roller 4. The primary stationary drum 2 is stationary, so the cable on the primary stationary drum 2 has a stationary end, while the stationary end is used for connection to signal processing equipment of the mother ship. And the moving end of the cable is wound on a second movable roller 5 after passing through a central frame 3 and a movable roller 4, and is connected with a detection element to realize remote distance and depth detection.
In summary, it can be seen that the present embodiment can convert the rolling dynamic state of the cable into the static state, and one end of the dynamic state is used for being placed at a distance for detection and detection, or transmitting light, electrical signals and data, or conducting electricity. While the stationary end is intended to be connected to a signal processing device of the mother vessel.
