Abstract
The utility model discloses a levitation type optical fiber which has two integrated parts of a levitation cable and a gravity cable whose cable cores are provided with shroud sheath optical fibers, signal transmission wires, electricity conductive conductors and central strengthening devices. The cable core of the levitation cable is covered by a strengthening layer and an outside sheath sequentially. The utility model is at suspended state in water and can be connected to the operation device that is at the lower end of the gravity cable or to the control device on the boats or platform on the water. The utility model can conveniently realize electricity power transmission, signal sending, image transmission between water surface and the under water.
Description
Affiliated technical field
The utility model belongs to a kind of optical cable, especially under water the optical cable of Shi Yonging.
Background technology
Existing underwater optical cable generally all is heavy cable, be sunken to the bottom, the bottom that can only fixedly be laid in is made transmission signals and is used, for the use occasion that not only needs to carry out underwater operation but also can only on the water surface, control, as realizing transmitting electric power, sending the optical cable that is connected of functions such as signal, images on the water surface with between the underwater operation point, existing underwater optical cable just is difficult to adapt to.
Summary of the invention
In order to overcome the deficiency of existing underwater optical cable function singleness, the utility model provides a kind of floated underwater optical cable, it is suspended state in water, can as on the water surface with the optical cable that is connected between underwater operation is, realize transmitting electric power, sending functions such as signal, images easily.
The utility model provides floatedly has buoyancy cable and the gravity cable two parts that fuse with optical cable under water, the buoyancy cable wrap is drawn together cable core (8) and oversheath (7) thereof, tight tube fiber (1), signal transmssion line (2), transmission pressure (4) and central reinforce member (3) are set in cable core (8), foaming inner sheath (5) and enhancement Layer (6) are set between cable core (8) and oversheath (7); The gravity cable wrap is drawn together cable core (8) and oversheath (7) thereof, and tight tube fiber (1), signal transmssion line (2) transmission pressure (4) and central reinforce member (3) are set in cable core (8), between cable core (8) and oversheath (7) enhancement Layer (6) is set.
The utility model is owing to be divided into buoyancy cable and the gravity cable two parts that fuse, whole optical cable presents suspended state in water, below the gravity cable sinks to, the buoyancy cable upwards floats, just can the operation instrument that lies in gravity cable lower end and be located at ship on the water surface or platform on control instrument connect together, can realize transmitting electric power on the water surface and under water, send functions such as signal, images easily.
Description of drawings
Fig. 1 is the cross sectional representation of buoyancy cable of the present utility model (A figure) and gravity cable (B figure).
Cable core in the drawings, 1, tight tube fiber, 2, signal transmssion line, 3, central reinforce member, 4, transmission pressure, 5, the outer foaming inner sheath of cable core, 6, enhancement Layer, 7, oversheath, 8.
Embodiment
Make the buoyancy cable earlier, tight tube fiber (1), signal transmssion line (2), transmission pressure (4), the central reinforce member (3) that cable core (8) is interior gone ahead of the rest stranded and coated with expanded material, outsourcing aramid fiber enhancement Layer (6) again, coat polyurethane oversheath (7) then, when making gravity cable section, cable core (8) stranded constant removes foaming inner sheath (5), thicken aramid fiber enhancement Layer (6) simultaneously, so that the utility model external diameter is constant.The making length of buoyancy cable and gravity cable is decided according to request for utilization.
Claims (1)
1, a kind of floated optical cable of using under water, it is characterized in that having buoyancy cable and gravity cable two parts of fusing, the buoyancy cable wrap is drawn together cable core and oversheath thereof, tight tube fiber, signal transmssion line, transmission pressure and central reinforce member are set in cable core, foaming inner sheath and enhancement Layer are set between cable core and oversheath; The gravity cable wrap is drawn together cable core and oversheath thereof, and tight tube fiber, signal transmssion line, transmission pressure and central reinforce member are set in cable core, between cable core and oversheath enhancement Layer is set.
