The working principle of this embodiment is as follows: under the execution of the pushing mechanism, the internal cable of the hydroelectric power station can be straightened and pulled, and the generated pretightening force is used for keeping stable under the influence of wind power received by the external cable, so that the condition that bolts are unscrewed at the connection part of the external cable and a power output pile of a generator set due to the influence of wind power can be avoided; with the help of the pressure sensor 9 and the control transmission mechanism, the pushing mechanism can automatically run to straighten and pull the cable;
When the external penetrating-out direction of the internal cable of the hydroelectric power station is regulated in the installation process, the external computer is operated, the control transmission mechanism calculates and operates, the rotation-carrying mechanism can drive the wire holding mechanism to rotate, and the external penetrating-out direction of the internal cable of the hydroelectric power station can be regulated;
when the external cable is affected by transverse wind power and swings, the control transmission mechanism calculates and operates, the cycloid mechanism swings in the maximum direction and the angle according to the wind power of the cable, lateral support pre-tightening swing control of the cable is achieved, reciprocating swing amplitude and speed are reduced, and further the connection lasting stability of the cable and a power output pile of the generator set is further guaranteed.
