Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 As shown, an underwater dynamic cable counterweight device includes a counterweight device connecting frame 1 and an underwater dynamic cable 6 disposed at the middle position of the counterweight device connecting frame 1.

[0025] An internal fitting airbag 7 is provided at the middle side of the counterweight device connecting frame 1. A side connecting column 8 is provided at the side of the counterweight device connecting frame 1. An internal telescopic connector 16 is provided at the middle of the side connecting column 8. A central compression threaded column 9 is provided at the side of the internal telescopic connector 16 via a rotating shaft. A rotating connecting knob 10 is provided at the side of the central compression threaded column 9. Rotating the central compression threaded column 9 can compress the internal telescopic connector 16, allowing the gas inside to enter the internal fitting airbag 7. The inner side of the counterweight device connecting frame 1 can be compressed and fitted to the outer side of the underwater dynamic cable 6. The rubber airbag can increase the friction between the counterweight device and the underwater dynamic cable 6, thereby effectively improving the installation stability of the counterweight device for the underwater dynamic cable 6.

[0026] like Figure 1 As shown, the outer side of the rotating connection knob 10 is textured. The rotating connection knob 10 and the central extrusion threaded column 9 are an integral structure. The texture on the outer side of the rotating connection knob 10 can increase the friction with the user's hand, thereby making it easier for the user to rotate.

[0027] like Figure 1 As shown, a flip-connecting post 2 is provided at the middle position of the upper and lower sides of the counterweight device connecting frame 1. The flip-connecting post 2 is rotatably connected to the counterweight device connecting frame 1 through a rotating shaft. The outer surface of the flip-connecting post 2 has an external thread structure, and a rotating compression fastening knob 3 is rotatably connected at its outer side. The rotating compression fastening knob 3 is connected to the flip-connecting post 2 by rotation. In use, adjacent counterweight device connecting frames 1 are spliced ​​together, and then the two counterweight device connecting frames 1 are squeezed together by rotating the flip-connecting post 2 and rotating the compression fastening knob 3.

[0028] like Figure 1As shown, a side connecting post 4 is provided on the side of the counterweight device connecting frame 1. The side connecting post 4 is connected to the counterweight device connecting frame 1 by welding. A connecting counterweight ball 5 is provided on the side connecting post 4. The connecting counterweight ball 5 can increase the weight of the counterweight device connecting frame 1.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, a connecting tube 11 is provided on the upper side of the counterweight ball 5, located in the middle position. A liquid extraction box 12 is provided on the upper side of the connecting tube 11. An internal micro water pump 17 is provided in the middle position of the liquid extraction box 12. An inlet / outlet port 13 is provided on the side of the internal micro water pump 17. A connecting tube 2 14 is provided on the upper side of the liquid extraction box 12. An upward floating auxiliary ball 15 is provided on the upper side of the connecting tube 2 14. An outer protective skin layer 18 is provided on the outer side of the upward floating auxiliary ball 15. An internal foam layer 19 is provided on the inner side of the upward floating auxiliary ball 15. An internal air passage 20 is provided in the middle of the built-in foam layer 19. The liquid extraction box 12 can extract and release the liquid inside by the built-in micro water pump 17. When the liquid inside the liquid extraction box 12 is extracted, the gas will enter the liquid extraction box 12 along the floating auxiliary ball 15, which can increase its buoyancy. This allows the counterweight device of the underwater dynamic cable 6 to float up partly, and vice versa. After the improvement of this utility model, the counterweight device of the underwater dynamic cable 6 can adjust the overall buoyancy of the counterweight, thereby effectively improving the practicality of the counterweight device of the underwater dynamic cable 6.
