[0026] In order to facilitate the fixed connection of the umbilical cable with other devices and improve the use effect, as Figures 1-4 shown, a umbilical cable with an electromagnetic shielding structure according to the present utility model includes an outer sheath 1 of the umbilical cable, an FPC electromagnetic shielding film 3 and a fastening assembly 4. A cable 8 is arranged inside the outer sheath 1 of the umbilical cable. A stainless steel pipe 6 and an optical fiber cable 9 are respectively arranged outside the cable 8. An inner sheath 5 is sleeved outside the cable 8, the stainless steel pipe 6 and the optical fiber cable 9. The FPC electromagnetic shielding film 3 is adhesively connected to the inner side of the inner sheath 5 by hot melt adhesive;

[0027] A fastening assembly 4 is sleeved on the lower end of the periphery of the umbilical cable outer sheath 1. The fastening assembly 4 includes a first fastening clamp 401, a second fastening clamp 402, ear plates 403 and a connecting plate 405.

The ear plates 403 are respectively connected to both sides of the first fastening clamp 401 and the second fastening clamp 402. Connecting plates 405 are respectively fixed at both ends of the first fastening clamp 401 and the second fastening clamp 402.

[0028] During use, the FPC electromagnetic shielding film 3 can effectively weaken the energy of electromagnetic waves and prevent the propagation of electromagnetic waves, enabling the umbilical cable to have good electromagnetic shielding performance.

[0029] Personnel can use the threaded connection method to sleeved the connector 10 on the top of the umbilical cable outer sheath 1. The connector 10 can stably physically connect the umbilical cable with other devices, so as to stably transmit hydraulic power, power supply, communication signals and chemical agents.

[0030] By using the connecting plate 405, bolt holes 406, fastening bolts 407 and fastening nuts 408, the first fastening clamp 401 and the second fastening clamp 402 can be tightly connected, and then the first fastening clamp 401 and the second fastening clamp 402 can be tightly arranged on the periphery of the bottom of the umbilical cable outer sheath 1, so that the umbilical cable outer sheath 1 can be connected to a preset underwater base or bracket through the first fastening clamp 401 and the second fastening clamp 402, thereby preventing the umbilical cable from swinging caused by the impact force of water, and further enhancing the stability of transmission.

[0031] Exemplarily, as Figure 4 shown, the fastening assembly 4 further includes mounting holes 404, bolt holes 406, fastening bolts 407 and fastening nuts 408.

Fastening bolts 407 and fastening nuts 408 are respectively arranged on both sides of the connecting plate 405.

[0033] Exemplarily, as Figure 2 shown, the FPC electromagnetic shielding film 3 is arranged on the inner side of the inner sheath 5.

[0034] During use, the inner sheath 5 can protect the FPC electromagnetic shielding film 3 from extrusion, thereby improving the stability of the FPC electromagnetic shielding film 3.

[0035] Exemplarily, as Figure 1 shown, an external thread 12 is provided on the outer side of the upper end of the umbilical cable outer sheath 1.

[0038] Exemplarily, as Figure 2 shown, a filling rope 7 is provided between the cable 8, the stainless steel pipe 6, the connector 10 and the inner sheath 5.

[0039] During use, the filling rope can fill the gaps between the cable 8, the stainless steel pipe 6, the connector 10 and the inner sheath 5 inside the umbilical cable, making the internal structure of the umbilical cable more compact, reducing the entry of impurities such as water flow and sediment caused by excessive space, and improving the overall sealing performance and stability of the umbilical cable.

[0040] When the utility model is in use, the inner sheath 5 is sleeved on the peripheries of the cable 8, the stainless steel pipe 6 and the connector 10, and can effectively fix the cable 8, the stainless steel pipe 6 and the connector 10 inside the umbilical cable, enabling the cable 8, the stainless steel pipe 6 and the connector 10 to all operate smoothly. Among them, the FPC electromagnetic shielding film 3 inside the inner sheath 5 can effectively block the propagation of electromagnetic waves and weaken the energy of electromagnetic waves, enabling the umbilical cable to have good electromagnetic shielding performance;

[0041] Furthermore, through the external thread 12 and the internal thread 13, the connector 10 can be sleeved on the top of the umbilical cable outer sheath 1 by means of threaded connection, and the connector 10 can be used to stably physically connect the umbilical cable with other devices, so as to stably transmit hydraulic power, power supply, communication signals and chemical agents;

[0042] Furthermore, the operator can use the connecting plate 405, bolt holes 406, fastening bolts 407 and fastening nuts 408 to tightly connect the first fastening clamp 401 and the second fastening clamp 402, and then can tightly set the first fastening clamp 401 and the second fastening clamp 402 around the bottom of the umbilical cable outer sheath 1, so that the umbilical cable outer sheath 1 can be connected to a preset underwater base or bracket through the first fastening clamp 401 and the second fastening clamp 402. This method can prevent the umbilical cable from swinging caused by the impact force of water, and further enhance the transmission stability.
