[0020] The beneficial effects of the present invention are:

[0021] Compared with the existing underwater cables, the present invention is provided with an airbag jacket and a fixing bracket on the cable, and an airbag gap is provided in the airbag jacket. Since the airbag jacket is made of silicone or silicone rubber, when the airbag gap is inflated, expansion deformation will occur to form air buoyancy on the cable, which will generate buoyancy on the cable when the underwater mobile device is used, reducing the load of the underwater mobile device when moving. The problem that the underwater cable will sink directly when used underwater is solved. The cable is filled with gas to increase buoyancy, reduce the load of the underwater mobile device, and thus extend the endurance of the underwater mobile device.

[0022] The design of the airbag gap and the tensioning connecting column of the underwater cable enables the cable to better disperse the pressure when subjected to external pressure, thereby improving the cable's pressure resistance. At the same time, when used underwater, it can be inflated to increase buoyancy while ensuring pressure resistance.

The design of the airbag jacket further enhances the protective performance of the cable. The airbag gap provides additional buffering and pressure resistance, effectively reducing the impact of external pressure on the cable.

[0023] The pneumatic connection ring set on the protective jacket, as well as the connection between the air intake check valve and the exhaust check valve, effectively increase the buoyancy of the cable underwater. The function of the air intake check valve is to guide the gas into the gap between the air bags to inflate it, thereby increasing the buoyancy of the cable. The exhaust check valve is used to discharge the gas in the gap between the air bags so as to adjust the buoyancy of the cable when necessary. This design improves the stability of the cable underwater, reduces the shaking and twisting of the cable in the water, and thus improves the quality and reliability of signal transmission. At the same time, this design also makes the cable more convenient to use and reduces costs.

In addition, the airbag gap can also provide a certain buffering effect to protect the cable from impact and damage in the underwater environment.

DETAILED DESCRIPTION

[0035] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Figure 1 to Figure 9 As shown, in one embodiment of the present invention, there is a built-in airbag gap underwater cable, including a first inner core 1, a second inner core 2, a fixing bracket 3, an airbag jacket 4 and a protective jacket 5, wherein the second inner core 2 is provided with a plurality of second inner cores 2 surrounding the outer periphery of the first inner core 1, the fixing bracket 3 is formed by extrusion of silicone rubber, and the first inner core 1 is extruded and connected with the plurality of second inner cores 2; the airbag jacket 4 is coated on the outside of the fixing bracket 3, and the protective jacket 5 is arranged on the outside of the airbag jacket 4; the airbag jacket 4 includes an inner connection Ring 41, outer connecting ring 42 and tensioning connecting column 43, an airbag gap 44 is set between the inner connecting ring 41 and the outer connecting ring 42, a plurality of tensioning connecting columns 43 are set, a plurality of the tensioning connecting columns 43 are set in the airbag gap 44, and the airbag gap 44 is spaced to form a single airbag, a plurality of the tensioning connecting columns 43 are opposite to a plurality of second inner cores 2, the tensioning connecting column 43 is used to connect the inner connecting ring 41 with the outer connecting ring 42, the inner connecting ring 41 is connected to the fixing bracket 3, and the outer connecting ring 42 is connected to the protective jacket 5. In this embodiment, an airbag jacket 4 and a fixing bracket 3 are set on the cable, and an airbag gap 44 is set in the airbag jacket 4. Since the airbag jacket 4 is made of silicone or silicone rubber, when the airbag gap 44 is inflated, expansion deformation will occur to form air buoyancy on the cable, which generates buoyancy on the cable when the underwater mobile device is used, thereby reducing the load when the underwater mobile device moves. The problem that underwater cables sink directly when used underwater is solved by filling the cables with gas to increase buoyancy and reduce the load on underwater mobile devices, thereby extending the endurance of underwater mobile devices.

[0038] In the above embodiment, the underwater cable is designed with an airbag gap 44 and a tensioning connecting column 43, so that the cable can better disperse the pressure when subjected to external pressure, thereby improving the cable's ability to resist pressure. At the same time, when used underwater, while ensuring the ability to resist pressure, it can also be inflated to increase buoyancy. Multiple second inner cores 2 surround the first inner core 1, and the connection of the fixed bracket 3 forms a sturdy structure that can withstand underwater pressure and external impact. The design of the airbag jacket 4 further enhances the protective performance of the cable. The airbag gap 44 provides additional buffering and pressure resistance, effectively reducing the impact of external pressure on the cable. The setting of the protective jacket 5 provides comprehensive protection for the cable to prevent moisture, corrosion and other factors from damaging the cable.

[0039] The protective jacket 5 is provided with a pneumatic connection ring 6, and the pneumatic connection ring 6 is provided with an air intake check valve 61 and an exhaust check valve 62. The air intake check valve 61 and the exhaust check valve 62 are both connected to the airbag gap 44. The air intake check valve 61 is used to guide the air intake of the airbag gap 44. The airbag gap 44 expands after being inflated to increase the buoyancy of the cable underwater. The exhaust check valve is used to discharge the gas in the airbag gap 44. In this embodiment, the pneumatic connection ring 6 provided on the protective jacket 5 and the connection of the air intake check valve 61 and the exhaust check valve 62 effectively increase the buoyancy of the cable underwater. The function of the air intake check valve 61 is to guide the gas into the airbag gap 44, so that it is inflated and expanded, thereby increasing the buoyancy of the cable. The exhaust check valve is used to discharge the gas in the airbag gap 44 so as to adjust the buoyancy of the cable when needed. This design improves the stability of the cable underwater, reduces the shaking and distortion of the cable in water, and thus improves the quality and reliability of signal transmission. At the same time, this design also makes the cable more convenient to use and reduces costs.

[0040] The first inner core 1 includes a first insulating outer jacket 11 and a signal inner core 12 disposed in the first insulating outer jacket 11, wherein the signal inner core 12 is provided with at least two strands; specifically, the second inner core 2 includes a second insulating outer jacket 21 and a conductive inner core 22 disposed in the second insulating outer jacket 21, wherein the conductive inner core 22 is provided with at least two strands; the fixing bracket 3 is provided with a separation groove 31 between the first inner core 1 and the second inner core 2, wherein the separation groove 31 is used to separate the first inner core 1 from the second inner core 2. In this embodiment, the first inner core 1 and the second inner core 2 respectively include an insulating outer jacket and a conductive inner core 22, and a signal inner core 12 and a conductive inner core 22 disposed therein, and this design enables the cable to better transmit signals and electrical energy, and improves the stability and reliability of data transmission. The fixing bracket 3 is provided with a separation groove 31 between the first inner core 1 and the second inner core 2, and is used to separate the first inner core 1 from the second inner core 2. This structural design effectively avoids mutual interference between different inner cores and ensures the clarity and accuracy of signal transmission. The signal inner core 12 and the conductive inner core 22 are both provided with at least two strands. This multi-strand design increases the stability of signal transmission and power transmission, and reduces signal loss and energy loss. The design of the separation groove 31 adopts a round hole groove, which further reduces the weight of the cable and increases buoyancy.

[0041] The fixed bracket 3 is provided with a telescopic cavity 32 between two adjacent second inner cores 2, and arcuate surfaces 321 are provided on both sides of the telescopic cavity 32, and the arcuate surfaces 321 are coaxially arranged with the adjacent second inner cores 2. In this embodiment, the telescopic cavity 32 can flexibly adapt to the changes in the internal pressure to ensure that the connection between the fixed bracket 3 and the second inner core 2 is tight and stable. At the same time, the arcuate surface 321 is coaxially arranged with the second inner core 2, which effectively reduces the friction and damage to the second inner core 2 and improves the service life of the cable. The setting of the arcuate surface 321 makes the connection between the fixed bracket 3 and the second inner core 2 tighter, reduces the gap, reduces the impact of the underwater environment on the cable, and increases the stability and reliability of the cable. Due to the complexity of the underwater environment, the cable needs to have good adaptability and stability. The design of the telescopic cavity 32 enables the cable to better adapt to the changes in the underwater environment, ensures the stability of signal transmission and energy transmission, and improves the efficiency and reliability of underwater work.

In this embodiment, the silicone or silicone rubber has excellent elasticity and corrosion resistance, can effectively seal the inside of the airbag, prevent water and impurities from entering the airbag gap 44, and protect the internal cables and components from damage. In addition, it can also effectively expand and contract during inflation or vacuum exhaust, and can well restore to its original state even after expansion and contraction.

[0043] The two sides of the tensioning connecting column 43 are symmetrically provided with tensioning expansion grooves 431, which are deformed when the airbag gap 44 is inflated and evacuated to change the shape of the single airbag; in this embodiment, the tensioning expansion grooves 431 can be deformed when the airbag gap 44 is inflated and evacuated to change the shape of the single airbag, so that the airbag can adjust its shape according to the changes in the underwater environment, thereby improving the adaptability of the entire system to the dynamic changes of the water flow. Through the deformation of the tensioning expansion grooves 431, the shape of the single airbag can be accurately controlled, thereby adjusting the buoyancy and stability of the airbag to ensure good performance under different underwater working conditions. By adjusting the shape of the airbag, the resistance between the airbag and the water flow can be reduced, the hydrodynamic loss of the underwater cable system can be reduced, and the operating efficiency of the system can be improved.

[0044] A through slot is provided on the tensioning connecting column 43, and the through slot is used to connect two adjacent single airbags. In this embodiment, the through slot is used to connect the single airbags, so that the gas in multiple single airbags can be inflated or exhausted synchronously during inflation or exhaust.

[0045] The inner circumference of the pneumatic connection ring 6 is provided with a sealing connection member 63, which is in sealing contact with the outside of the protective jacket 5. In this embodiment, a sealing connection is provided between the sealing connection member 63 and the protective jacket 5, thereby ensuring sealing and stability during inflation or deflation.
