DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 A zero-buoyancy cable in this embodiment includes an outer protective layer 1, a tensile bearing layer 2 is fixed inside the outer protective layer 1, a connecting block 3 that penetrates the tensile bearing layer 2 is fixed on the top of the outer protective layer 1, a through hole is opened on the top of the outer protective layer 1, and a sealing gasket is fixed in the through hole. The sealing gasket can effectively improve the sealing of the connection between the outer protective layer 1 and the connecting block 3, so that liquid is not easy to flow into the interior of the whole.

[0025] In addition, the interior of the sealing gasket is fixed to the connecting block 3, and the interior of the connecting block 3 is slidably connected to a pushing component 4 that passes through the top of the connecting block 3. The pushing component 4 includes a sealing plate 401 that is slidably connected to the connecting block 3, and the sealing plate 401 is used to push the gas to move. A card block 402 is fixed to the bottom of the sealing plate 401, and the card block 402 is used to connect with the card plate, so that the card plate can be periodically driven to move. A pushing rod 403 that passes through the outside of the connecting block 3 is fixed to the top of the sealing plate 401, and a control block 404 is fixed to the top of the pushing rod 403. The pushing rod 403 and the control block 404 are used to facilitate pushing the sealing plate 401 to move, so that the whole is more practical. The interior of the pushing rod 403 is slidably connected to a connecting rod 405 that passes through the pushing rod 403, and the connecting rod 405 is used to directly push the sealing block 501 to move, so that the internal gas can be released, and the pushing component 4 is used to push the gas to move.

[0026] Furthermore, an opening and closing component 5 is slidably connected inside the connecting block 3, and the opening and closing component 5 is used to control the closed state of the connecting block 3. An air inlet 6 is fixed on the right side of the connecting block 3, and a cover plate is threadedly connected to the outer surface of the air inlet 6. A threaded strip is fixed to the outer surface of the air inlet 6, and a threaded hole matching the threaded strip is provided on the left side of the cover plate. The cover plate is used to close the air inlet 6, and the threaded strip is provided to facilitate the installation of the external bottle body, making the whole more practical. A connecting pipe 7 is fixed inside the connecting block 3, and a connecting groove is provided inside the connecting block 3. The air inlet 6 and the connecting pipe 7 are both connected to the connecting groove and to each other, so that the gas can enter the interior of the connecting block 3. The top of the connecting pipe 7 is slidably connected to a card plate that is plugged into the card block 402. The card plate is used to control the switch of the connecting pipe 7. A limit plate located inside the connecting pipe 7 is fixed to the outer surface of the card plate. The limit plate is used to limit the movement of the card plate, so that the card plate will periodically lose its fixation with the card block 402. An inner protective layer 8 is fixed to the inside of the tensile bearing layer 2, and a cable 9 is fixed to the inside of the inner protective layer 8.

[0027] In this embodiment, a buoyancy adjustment layer is formed between the tension bearing layer 2 and the inner protective layer 8. By adding lighter gas to the buoyancy adjustment layer, the overall buoyancy can be adjusted. The interior of the inner protective layer 8 is filled with fillers. The set fillers effectively improve the stability of the internal cable 9, making the whole more practical.

[0028] In general, the sealing gasket can effectively improve the overall sealing performance, and the connecting rod 405 can conveniently push the sealing block 501 to move. In addition, the pushing component 4 can push the gas to move. The overall structure is simple and the buoyancy can be effectively adjusted, making the overall structure more practical.

[0029] See also Figure 4In order to adjust the buoyancy, the opening and closing assembly 5 in this embodiment includes a sealing block 501 that is tightly fitted with the connecting block 3. The sealing block 501 can block the venting groove to prevent the loss of gas. The left and right sides of the sealing block 501 are fixed with sliding plates 502 that are slidably connected to the connecting block 3. The bottom of the sliding plate 502 is fixed with a supporting spring 503 that is fixed to the connecting block 3. The supporting spring 503 can support the sealing block 501, so that the connecting block 3 is kept closed. The sliding plate 502 A telescopic rod 504 fixed to the connecting block 3 is fixed to the top of 02, and the telescopic rod 504 includes an extension rod fixed to the connecting block 3, and the outer surface of the extension rod is slidably connected to the extension block fixed to the sliding plate 502. The setting of the telescopic rod 504 can make the movement of the sealing block 501 more stable, thereby effectively improving the overall stability. A ventilation groove is opened inside the connecting block 3, and a support block 505 is fixed to the top of the sealing block 501. The setting of the support block 505 is used to facilitate the connecting rod 405 to push the sealing block 501 to move.

[0030] In general, under normal circumstances, the support spring 503 will support the sealing block 501, so that the connecting block 3 remains closed as a whole. When the air pressure is too high, the sealing block 501 will move downward, so that the gas can enter the buoyancy adjustment layer through the ventilation groove, and the overall structure will be lowered, which can effectively adjust the buoyancy and make the whole more practical.

[0031] The working principle of the above embodiment is:

[0032] (1) When the overall buoyancy needs to be improved, the bottle containing lighter gas is installed on the air inlet 6, and the control block 404 is pulled upward, so that the push rod 403 pulls the sealing plate 401 to move, and due to the clamping connection between the clamping block 402 and the clamping plate, the clamping plate opens the connecting pipe 7, and then the gas inside the bottle is drawn into the connecting block 3. When it continues to move upward, the limit plate limits the movement of the clamping plate, so that the clamping block 402 loses connection with the clamping plate, and then the clamping plate closes the connecting pipe 7 again. The overall structure is simple, and the external gas is effectively drawn into the interior of the connecting block 3, which is convenient for the subsequent addition of the buoyancy adjustment layer.

[0033] (2) When the push rod 403 moves downward to push the sealing plate 401 to move, the air pressure inside the connecting block 3 will increase, so that the supporting spring 503 can no longer continue to support the sealing block 501. As a result, under the push of the air pressure, the sealing block 501 moves downward to expose the ventilation groove, and then the gas enters the buoyancy adjustment layer through the ventilation groove. When the air pressure decreases, the supporting spring 503 will make the sealing block 501 move upward again to close the ventilation groove. The overall structure is simple and the buoyancy is effectively adjusted, thereby effectively improving the overall practicality.
