[0165] like Fig.10As shown, the third guide unit 70 includes a third guide unit 71 and a third through-hole element 72. The third guide element 71 is disposed at the bottom end of the first guide unit 30 and rotates around the central axis of the rotating unit 20; the third through-hole element 72 is disposed at the end of the third guide element 71 for passing the umbilical cable.

[0166] Specifically, the third guide element 71 is disposed at the bottom end of the first guide element 31 and rotates around the central axis of the first rotating element 21 .

[0167] More specifically, the third guide element 71 is disposed at the inner end of the connecting member.

[0168] In some of the embodiments, the third guide element 71 is integrally formed with the connecting member.

[0169] The size of the third guide element 71 matches the size of the connecting member. Generally, the axial size of the third guide element 71 is smaller than the vertical distance from the bottom end of the connecting member to the bottom plate element 12.

[0170] In some embodiments, the cross section of the third guide element 71 is L-shaped. Specifically, the third guide element 71 includes a second longitudinal guide and a second transverse guide. The top of the second longitudinal guide is connected to the end of the connecting member; the second transverse guide is arranged at the bottom of the second longitudinal guide and is located below the first rotating element 21, and the second transverse guide is provided with a third through hole element 72.

[0171] In some of the embodiments, the third guide element 71 is a ceramic cable guide.

[0172] The third through-hole element 72 is arranged through the second transverse guide.

[0173] In some of the embodiments, the center of the third through hole element 72 is arranged to coincide with the extension line of the central axis of the first rotating element 21 .

[0174] In some of the embodiments, the cross-section of the third through-hole element 72 is circular.

[0175] In some of the embodiments, the third through-hole element 72 is a third fairlead.

[0176] The method of using this embodiment is as follows:

[0177] The cables are wound around the cable drum element 51 in the same direction from the bottom to the top. The cables pass through a plurality of second guide elements 41 located on the first guide element 31 from the top, and then pass through the third through-hole element 72 to be connected to the hydrophone or other equipment weights downward.

[0178] The advantage of this embodiment is that, by providing the third guide unit, the release angle of the cable inside the frame unit can also be fixed, thereby reducing the wear of the frame unit when the cable is released.

[0179] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
