Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the following detailed description.

A plastic optical fiber floating optical cable for an underwater ROV comprises a plastic optical fiber 1, a filling fiber bundle 2, a metal armored reinforcing sleeve 3, a fiber reinforcing sleeve 4 and an outer sheath 5.

According to the practical application demand, plastic optical fiber 1 can be single or many, refer to fig. 1, plastic optical fiber 1 of this embodiment is two, including metal armor uide bushing 3 wraps two plastic optical fiber 1 together, leave the space between metal armor uide bushing 3 and two plastic optical fiber 1, fill fiber bundle 2 and fill this space, metal armor uide bushing 3 cooperates jointly with filling fiber bundle 2, on the one hand, metal armor uide bushing 3 can make plastic optical fiber 1 have good tensile property, on the other hand, filling fiber bundle 2 can make plastic optical fiber 1 obtain certain buffer performance in metal armor uide bushing 3, not only the resistance to compression and the bending resistance of plastic optical fiber 1 have been improved, and make the holistic compliance of optical cable better.

The metal armored reinforcing sleeve 3 can be a stainless steel armored reinforcing sleeve, and is more suitable for being used in a humid environment. The filling fiber bundle 2 can be specifically an aramid fiber bundle, and the aramid fiber bundle has the characteristics of light weight and softness, so that the protection effect on the plastic optical fiber 1 can be further improved.

Referring to fig. 1, a fiber reinforced sheath 4 and an outer sheath 5 are sequentially wrapped outside a metal armored reinforcing sleeve 3. The fiber reinforced sleeve 4 can ensure that the whole optical cable has higher tensile strength, and is beneficial to prolonging the service life of the optical cable under long-term underwater motion operation. Specifically, fibre reinforcing cover 4 is aramid fiber woven fabrics fibre cover, and aramid fiber woven fabrics fibre cover has soft and tough performance, can also play the effect with the isolation of metal armor uide 3 and oversheath 5, reduces the damage that metal armor uide 3 caused to the friction of oversheath 5, further improves the life of optical cable.

The outer sheath 5 is made of TPU foaming material, the thickness of a single layer of the outer sheath is preferably 1/5-1/3 of the diameter of the optical cable, and the TPU foaming material has the characteristics of small density, high elasticity and good waterproof performance, so that the outer sheath 5 not only can play a waterproof effect as the outermost layer of the optical cable, but also can enable the optical cable to have lighter self weight, is beneficial to floating movement on water and is not easy to influence the normal operation of an ROV (Rov), in addition, when the optical cable is bent in movement or needs to be twisted and wound back, the outer sheath 5 can play a good buffering effect on the plastic optical fiber 1 inside, and further reduces the damage caused by pulling, folding and pressing of the plastic optical fiber 1 from the outside.
