[0045] Working principle: by adjusting the height of the first sliding frame 5 in the vertical direction through the lifting platform 3 and the first lifting device 4, the locking column 7 is flush with the locking cylinder 10, combined with the first telescopic device 8 to push the first sliding frame 5 along the lifting platform 3, and the locking column 7 cooperates with the locking cylinder 10 on the mounting frame 9 of the dike 2 to realize the stable and safe transfer of the inverter from the dike 2 to the maintenance ship.

[0046] The first telescopic device 8, the second telescopic device 132, the first lifting device 4 and the second lifting device 17 can be a non-hydraulic cylinder.

[0047] In this embodiment, please refer to Figure 3 The mounting frame 9 is arranged in V shape, the locking cylinder 10 is located in the middle of the V shape of the mounting frame 9, the locking device 13 includes two cylinders 131 fixedly connected with each other on the two arms of the mounting frame 9, the second telescopic device 132 and the positioning pin 133 are arranged in the cylinder 131, the second telescopic device 132 drives the relative movement of the positioning pin 133, and the end of the locking column 7 is provided with a locking hole 71 matched with the positioning pin 133.
