The tension of the steel wire rope is constant by setting a constant hydraulic motor inlet pressure, when the external pressure is greater than the set pressure, the hoisting winch 13 drum is dragged to rotate reversely to lower the steel wire rope, when the external pressure is less than the set pressure, the hoisting winch 13 drum rotates positively to tighten the steel wire rope, the steel wire rope keeps a tensioning state all the time, and therefore impact caused by wave heaving is reduced. Besides, encoders are arranged on the left hoisting winch 13 and the right hoisting winch 13, the releasing length of the steel wire rope can be measured, the vertical distance between the two hoisting points of the navigation body is not more than 100mm, and the problem that the head-to-tail height difference of the navigation device 12 is too large in the process of distribution, releasing and collecting is avoided, so that the turning damage is caused.
