[0025] The submarine cable tension automatic control device with a dancing wheel in this embodiment includes a rotating tray 1, a tractor 3, and a dancing wheel 7. A rotating base is mounted at the bottom of the rotating tray 1, on which the rotating tray 1 is rotatably mounted. A support frame 2 is fixed at the center of the rotating base, and a through-hole for the support frame 2 to pass through is defined in the center of the rotating tray 1. A rotating motor 8 is fixed to the rotating base, and a gear is mounted on the output shaft of the rotating motor 8. An annular rack is mounted on the outer annular surface of the rotating tray 1, and the gear and rack mesh with each other, thereby driving the rotating tray 1 to rotate. The upper end of the support frame 2 extends laterally to the outside of the rotating tray 1. A support platform 4 is fixed to the upper end of the support frame 2. The tractor 3 is fixed to the support platform 4, and a plurality of guide wheels 5 are installed at intervals on the support platform 4. The guide wheels 5 are installed in the traction direction of the tractor 3. The dancing wheel 7 is fixed below the support platform 4 and is installed in the traction direction of the submarine cable 6. The dancing wheel 7 is separated from the support frame 2 by a predetermined distance.

[0026] like Figure 2 FIG. 1 is a schematic structural diagram of a dancing wheel according to the present invention.

[0027] The bottom of the dancing wheel 7 shown is fixed with a base 73, which is fixedly mounted on the traction equipment platform. The upper end of the base 73 is fixed with a support rod 75, and the upper end of the support rod 75 is hinged with a connecting rod 72. A limit block 74 is fixed on the support rod 75 at the lower end of the connecting rod 72, and the limit block 74 supports and limits the connecting rod 72. When the connecting rod 72 is in a natural state, a certain angle is formed between the connecting rod 72 and the support rod 75. The dancing wheel 7 is rotatably mounted on the end of the connecting rod 72, and a displacement sensor 71 is fixedly mounted on the side of the dancing wheel 7.

[0028] like Figure 3 FIG. 1 is a schematic structural diagram of a tractor according to the present invention.

[0029] The illustrated tractor 3 has a traction motor 35 fixed to the side, and a traction sheave 37 rotatably mounted inside the tractor 3. The traction sheave 37 includes an active traction sheave and a passive traction sheave. The output shaft of the traction motor 35 is connected to the active traction sheave, and traction belts 36 are mounted on the active and passive traction sheaves. Two traction belts 36 are installed inside the tractor 3, arranged one above the other, forming a traction channel for the submarine cable 6 between the two traction belts 36. A fixing seat 33 is fixed to the housing of the tractor 3, to which a cylinder 32 is fixed.

[0031] Working principle: The submarine cable 6 extends from the rotating tray 1, passes through the tractor 3, guide wheel 5 and dancing wheel 7 in sequence, and the submarine cable 6 passes through the lower end of the dancing wheel 7. During the laying process of the submarine cable 6, as the tension of the submarine cable changes, the submarine cable 6 moves up and down against the dancing wheel 7, and the displacement of the submarine cable 6 is monitored by the displacement sensor 71. The displacement sensor 71 feeds back the data to the automatic controller, and the automatic controller processes the data and sends instructions to the rotating motor 8 and the tractor 3 to adjust the operating parameters of each electrical component, thereby controlling the pay-off speed of the submarine cable 6, thereby realizing tension control when laying the submarine cable 6.
