[0046] S4. The lifting motor 3 drives the lifting screw 4 to rotate, thereby moving the lifting platform 7 upward. During the upward movement of the lifting platform 7, the winch 9 is controlled to slowly reel in, so as to prevent the metal wire on the winch 9 from interfering with the rise of the lifting platform 7. Then, the lifting platform 7 pushes the cover plate 8 out of the water.

[0047] S5. The cover plate 8 is lifted by the winch 9 so that the cover plate 8 and the lifting platform 7 are separated.

[0048] S6. The cleaning personnel scrape off the dirt on the lifting platform 7, enter the salvage ship, and complete the garbage cleaning.
