Detailed Description

As shown in fig. 1, fig. 1 is a floating cable disclosed by the present invention, which adopts the combination of floating components and adds proper connection, so as to satisfy the requirement of floating function and improve the utilization efficiency of the floating cable.

Referring to fig. 1, the floating cable includes an outer sheath layer 100, an insulating layer 200, a copper core wire 300, a floating layer 400 and a filling layer 500, wherein the outer sheath layer 100 has a circular cross section, the insulating layer 200 is disposed at the center of the inner portion of the outer sheath layer 100, the insulating layer 200 has a copper core wire 300 at the center of the insulating layer 200, the insulating layer 200 and the copper core wire 300 have circular cross sections, and two insulating layers 200 and two copper core wires 300 are disposed; the floating layer 400 is distributed in the insulating layer 200 in a circumferential manner, and the floating layer 400 is filled with hydrogen; the filling layer 500 is a filamentous cotton fabric.

The diameter of the outer sheath layer 100 is 20cm, and the wall thickness of the outer sheath layer 100 is 1 cm.

The thickness of the insulating layer 200 is 2cm, the diameter of the copper core wire 300 is 1cm, and the diameter of the floating layer 400 is 4 cm.

The outer sheath layer 100 is a structure made of a PTFE foam material.

The floating layer 400 is internally provided with threads.

Referring to fig. 2, the floating cable further includes a connection sleeve having a cylindrical shape with external threads formed at both ends thereof, the external threads of the connection sleeve being engaged with the threads of the inside of the floating layer 400.

The density of the PTFE foaming material is 0.6 multiplied by 10³kg/m³Density of the insulating layer is 0.9X 10³kg/m³Copper density of 8.9X 10³kg/m³。

Taking a floating cable with the length of 1m, wherein the radius of an outer sheath layer is 0.1m, the diameter of a copper core wire is 0.005m, calculating the buoyancy received by the cable in water and the gravity of the cable, and because the mass of hydrogen and filamentous cotton fabrics is small, the buoyancy can be ignored, namely the gravity of the floating layer and the filling layer can be ignored, and the calculation result is as follows:

V_{floating cable}＝3.14*0.1*1＝3.14*10^-2m³，

The floating cable is subjected to buoyancy F_{Floating cable}＝ρ_{Water (W)}gV_{Floating cable}＝1000kg/m³*10N/kg*3.14*10^-2m³＝314N；

The gravity of the outer jacket layer, the insulating layer and the copper core wire is calculated as follows:

V_{outer sheath layer}＝3.14*0.1²*1＝3.14*10^-2m³，V_{Insulating layer}＝3.14*0.02²*1＝0.1256*10^-2m³，

V_{Copper core wire}＝3.14*0.005²*1＝0.00785*10^-2m³，V_{Floating layer}＝3.14*0.02²*1＝0.1256*10^-2m³，

m_{Outer sheath layer}＝0.6×10³kg/m³*3.14*10^-2m³＝18.84kg，

m_{Insulating layer}＝0.9×10³kg/m³*0.1256*10^-2m³＝1.1304kg，

m_{Copper core wire}＝8.9×10³kg/m³*0.00785*10^-2m³＝0.69865kg，

G_{Outer sheath layer}＝m_{Outer sheath layer}g＝188.4N，

G_{Insulating layer}＝m_{Insulating layer}g＝11.304N，

G_{Copper core wire ═}m_{Copper core wire}g＝6.9865N，

G_{Floating cable}＝G_{Outer sheath layer}+G_{Insulating layer}+G_{Copper core wire}＝206.6905N，

Due to G_{Floating cable}Less than F_{Floating cable}That is, the gravity of the floating cable is smaller than the buoyancy to which the floating cable is subjected, so that the floating can be realized.

The working process is as follows: the floating cable is placed into water, floating can be achieved due to the fact that the received buoyancy is larger than the self gravity of the floating cable, if the floating cable breaks, the copper core wire can be connected manually, then the threads of the connecting sleeve and the threads inside the opposite floating layer 400 are screwed up manually, and use of the floating cable is not affected.

To sum up, the utility model provides a pair of floating cable's advantage lies in: the utility model provides a floating cable, the buoyancy received when the utility model is put into water is larger than the gravity of the utility model, thereby realizing floating and convenient use; through setting up the adapter sleeve, when the fracture appears in the showy cable, manually twist the copper core line at both ends together, close the adapter sleeve soon again, do not influence the use of showy cable, improve the availability factor of showy cable.
