Underwater platforms typically need to surface to communicate, but this process is energy-intensive, unstable, and carries a high risk of exposure. Existing satellite communication methods for underwater platforms mainly include: fixed antenna floats, which need to be mounted on a platform and rely on the platform to surface before communication can occur; this method is power-intensive, and the antenna mechanism faces stringent water pressure requirements when the platform is submerged in deep water.

[0026] Example: Currently, satellite communication signals cannot penetrate water, especially at depths greater than 10m where the signal is significantly attenuated. Underwater platform 3 usually needs to surface to communicate, but surfacing consumes a lot of energy, is unstable, and poses a high risk of exposure.

[0027] Therefore, please refer to Figure 1 (Refer to) Figures 2 to 9This embodiment provides an auxiliary device for underwater platform communication, which solves the aforementioned technical problems. The auxiliary device mainly includes a float mechanism, a separation mechanism, and a self-sinking mechanism. The separation mechanism is detachably and sealed in a mounting groove on the underwater platform 3. The separation mechanism includes a first cylinder 4, an end cap 5, a sealing flange 6, an inflation port 7, and an antenna port 8. The first cylinder 4 is installed in the mounting groove. The end cap 5 is detachably installed on the opening of the first cylinder 4 via the sealing flange 6. The inflation port 7 and the antenna port 8 are respectively located on the inner wall of the first cylinder 4. One end of the communication antenna 2 is connected to the underwater platform 3 via the antenna port 8. The float mechanism is detachably installed within the cavity of the separation mechanism and includes a float body 1, an inflation assembly, and a communication antenna 2. The float body 1 is detachably folded and installed within the cavity of the first cylinder 4. The inflation assembly is located on the outer wall of the float body 1 and connected to the cavity of the float body 1. It is used to inflate the float body 1, causing it to expand and open the separation mechanism, detach from the first cylinder 4, and rise, thereby lifting the communication antenna 2 above the water surface. Furthermore, one end of the communication antenna 2 is connected to the underwater platform 3 via the separation mechanism, and the other end is connected to the float body 1. One end of the self-sinking mechanism is connected to the communication antenna 2, and the other end is adhered to the float body 1. After completing the communication task, it can puncture the float body 1 and sink, thereby reducing the risk of exposure of the underwater platform 3.

[0028] It should be noted that the sealing flange 6 is connected to the first cylinder 4 via plastic rivets 9; the end cap 5 is connected to the sealing flange 6 via locking screws 10. Furthermore, the first cylinder 4 is connected to the underwater platform 3 via an axial sealing ring and screws. The axial sealing ring ensures the sealing performance of the underwater platform 3 and guarantees the internal stability of the underwater platform 3. After the first cylinder 4 is installed in the mounting slot of the underwater platform 3, it forms a whole with the underwater platform 3, thereby ensuring the uniform distribution of surrounding water currents during normal submerged operation, reducing water noise, and improving stealth. The first cylinder 4 contains an antenna interface 8 and a start-up inflation signal interface, both of which are connected to the underwater platform 3. It can receive control signals from the underwater platform 3 and transmit satellite signals back to the underwater platform 3. This structure is based on existing technology, and its specific structure and working principle will not be elaborated here.

[0029] Furthermore, its float body 1 includes a retractable and interconnected ellipsoidal structure and a conical structure; the other end of the communication antenna 2 is connected to the top of the conical structure; and the inflation assembly is disposed on the bottom of the ellipsoidal structure.

[0030] Meanwhile, its inflation assembly includes a release valve 11, a first electric detonator 12, and multiple gas cylinders 13; the release valve 11 has a first gas passage 14 and a first connecting passage 15 spaced apart along a first direction, and the first gas passage 14 and the first connecting passage 15 are connected by multiple first connecting passages 16 extending along a second direction; the first gas passage 14 and the first connecting passage 15 both penetrate one end of the release valve 11 and are both sealed by a first plug 17; the first connecting passages 16 all penetrate one side of the release valve 11 and are all sealed by a second plug 18; the multiple gas cylinders 13 are respectively connected to the release valve 11, and their outlets are all connected to the first connecting passages 15; the first connecting passages 16 are provided with movable A piercing needle 19, which adjusts and isolates the first gas passage 14 from the first connecting passage 15, is used to pierce the gas outlet of the gas cylinder 13. A first spring 20 is fitted at one end of the needle 19, which keeps it in its initial position. The outlet of the first electric detonator 12 is connected to the first gas passage 14, releasing high-pressure gas into the passage to move the needle 19 and pierce the gas outlet of the gas cylinder 13. A first gas outlet passage 21, connected to the first connecting passage 15, is provided inside the release valve 11 along a third direction. This passage is connected to an inflation connector 22 on the release valve 11, which in turn connects to the float body 1 to inflate it. The first, second, and third directions are perpendicular to each other.

[0031] Specifically, the first plug 17 and the second plug 18 are connected to the release valve 11 via threads and a sealing gasket 23, which ensures that the first gas passage 14 and the connecting pipe are both sealed spaces. The first electric detonator 12 and the gas cylinder 13 are both connected to the release valve 11 via threads, and the gas cylinder 13 is sealed by the sealing gasket 23. The gas cylinder 13 stores high-pressure gas, including carbon dioxide, nitrogen, and helium.

[0032] In addition, the needle 19 includes a cylindrical body, on which a first limiting ring, a sealing ring and a second limiting ring are sequentially fitted. The sealing ring seals against the inner wall of the first connecting channel 16 to isolate the first gas channel 14 from the first connecting channel 15. At the same time, a needle-shaped piercing head is connected to the end of the cylindrical body near the gas cylinder 13, which is used to pierce the gas outlet of the gas cylinder 13.

[0033] The float body 1 is connected to the antenna interface 8 inside the first cylinder 4 via the communication antenna 2. The first electric detonator 12 in the inflation assembly on the float body 1 is connected to the start inflation interface 7 at the bottom of the first cylinder 4. The start inflation interface 7 can automatically detach from the start inflation interface 7 when the float body 1 is inflated and floats upward under the pull force. After receiving the start inflation signal, the first electric detonator 12 operates and releases high-pressure gas into the first gas passage 14, forming high pressure inside the first gas passage 14. The high-pressure gas then pushes the piercing needle 19 at the first connection. The gas cylinder moves in channel 16 toward the outlet of gas cylinder 13 until it punctures the outlet of gas cylinder 13. The gas released from gas cylinder 13 passes through the outlet of gas cylinder 13 in sequence through the first connecting channel 15 and the first outlet channel 21 and enters the inflation connector interface 22, thereby entering the float body 1 and inflating the float body 1. At this time, the end cap 5 and the sealing flange 6 are subjected to an outward force. When the force is greater than the pulling force of the plastic rivet 9, the end cap 5 and the sealing flange 6 fall off, and the float body 1 detaches from the inside of the first cylinder 4 due to its own buoyancy.

[0034] The inflation assembly achieves the effect of simultaneously activating two gas cylinders 13 using a first electric detonator 12 through the internal passage structure of the release valve 11. This arrangement can effectively reduce the volume of the entire inflation assembly. In other embodiments, the structural arrangement of the first connecting channel 16, the second plug 18, the gas cylinders 13, etc. in the inflation assembly can be adapted to different usage requirements.

[0035] The float body 1 is made of polyurethane adhesive tape, and its overall shape is conical at the top and ellipsoidal at the bottom. The top of the conical float has a hanging point for connecting to the communication antenna 2. By changing the size of the conical float, the height of the communication antenna 2 can be adjusted according to the requirements. During installation, the float body 1 is folded and stored inside the first cylinder 4. The communication antenna 2 is connected to the float body 1 and the underwater platform 3 through the antenna interface 8. When the underwater platform 3 transmits a start signal, the inflation component works to inflate the float body 1, causing it to expand. The end cap 5 on the first cylinder 4 is subjected to pressure. When the pressure exceeds the release force of the plastic rivet 9, the end cap 5 detaches from the first cylinder 4. The float body 1, due to buoyancy, detaches from the first cylinder 4 and rises, supporting the communication antenna 2 at a certain height above the water surface. The float body 1 has a conical structure on top and an ellipsoidal structure on the bottom. The inflation component is located at the bottom of the float body 1, resulting in a low center of gravity, ensuring stability in complex sea conditions and maintaining a stable attitude for the communication antenna 2. After completing its mission, the float body 1 can sink after receiving the signal from the underwater platform 3. Its simple structure, small packaging size, low price and easy installation provide a stable floating attitude for the antenna used for communication on the underwater platform 3, and it can sink after the mission is completed, reducing the risk of exposure, which has great practical value.

[0036] It should be noted that the self-sinking mechanism includes a second cylinder 24, a second electric detonator 25, and a firing pin 28. The interior of the second cylinder 24 has a stepped surface that divides the inner cavity of the second cylinder 24 into a first cavity 26 and a second cavity 27. The inner diameter of the first cavity 26 is larger than that of the second cavity 27. The gas outlet of the second electric detonator 25 extends into the first cavity 26 and can release high-pressure gas into the first cavity 26, thereby pushing the firing pin 28 to move and puncture the float body 1. A second spring 29 is sleeved on the end of the firing pin 28 near the float body 1. The second spring 29 serves to keep the firing pin 28 in its initial position. A vent hole 30 is opened on the side wall of the second cylinder 24 near the float body 1. One end of the second cylinder 24 is attached to the float body 1. When the firing pin 28 is in its initial position, its end is spaced a certain distance from the float body 1.

[0037] Upon receiving a signal transmitted from the underwater platform 3, the second electric detonator 25 inside the self-sinking mechanism is activated and releases high-pressure gas, which pushes the internal striking pin 28 to move and pierce the float body 1. After the float body 1 is punctured, the internal gas leaks out, and after losing buoyancy, it sinks itself, thereby reducing the risk of the underwater platform 3 being exposed.

[0038] Meanwhile, its inflation component is located at the bottom of the ellipsoidal bladder of the float body 1, resulting in a low center of gravity and a small sway angle under sea conditions, which can meet the attitude requirements of the communication antenna 2 for satellite communication of the underwater platform 3. Its self-sinking mechanism can receive the self-sinking signal of the communication antenna 2. After receiving the signal, it can puncture the float body 1, causing it to deflate and sink, achieving a concealment effect, which will not be elaborated here. The length of the communication antenna 2 can be determined according to the working depth of the underwater platform 3. Before operation, it can be wrapped and folded inside the first cylinder 4. When the length of the communication antenna 2 is deeper than the working depth of the underwater platform 3, the communication antenna 2 can act as a weight to further lower the center of gravity of the float body 1, making its floating stability better; when the length of the communication antenna 2 is shallower than the working depth of the underwater platform 3, the buoyancy of the float body 1 can ensure that the underwater platform 3 is in a stable suspended attitude in the water.

[0039] The underwater platform 3 adopts the structure of the existing technology, and its specific structural form and working principle will not be described in detail here; it has communication function and can transmit electrical signals. This embodiment only shows one of the external forms, and its internal structure is not limited.

[0040] In summary, this application provides an auxiliary device for underwater platform communication. The device includes a float mechanism and a separation mechanism. During installation, the float mechanism is folded and stored inside the separation mechanism. The communication antenna 2 is connected to the float mechanism and the underwater platform 3 through the separation mechanism. When the underwater platform 3 transmits a start signal, the inflation component operates to inflate the float body 1, causing it to expand and open the separation mechanism, then detach and rise, thereby supporting the communication antenna 2 at a certain height above the water surface, ensuring a stable attitude for the communication antenna 2 under complex sea conditions. This device has a simple structure, small overall size, low cost, and is easy to install. It provides a stable floating attitude for the antenna used for communication on the underwater platform 3 and has significant practical value.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
