[0002] The development of underwater ship cleaning can be divided into three stages: manual operation stage, mechanical operation stage and robot operation stage. In the early days, underwater ship cleaning was generally done by divers carrying cleaning brushes, and the cleaning brushes and brush materials were selected according to the type and thickness of the attachments. With the development of science and technology, remotely controlled submersibles (commonly known as underwater robots, ROVs for short) have gradually been used in the observation, inspection and repair of ship hull parts and devices below the waterline. Cleaning on the platform requires manual ascent to a certain height to clean the outer wall of the ship, so a platform lifting device is needed to perform the above operations.

[0003] A Chinese patent with patent number: CN112173032B discloses a ship cleaning platform, including a shell, a pad is provided at the lower end of the shell, there are four pads, and the four pads are evenly distributed at the lower end corners of the shell, the lower end of the shell is provided with an opening, the upper end of the shell is connected to a shell cover by screws, the upper end of the shell cover is provided with a first motor, the lower end of the first motor is provided with a first rotating shaft, a sleeve is welded to the upper end of the shell cover, a support rod is slidably sleeved in the sleeve, there are four sleeves, four sleeves are evenly distributed at the upper end of the shell cover, support rods are slidably sleeved in the four sleeves, a sealing plate is provided at the lower end of the support rod, and a sealing plate is slidably sleeved in the sleeve.

[0004] The above-mentioned shortcomings have the following disadvantages: first, when the overall device is converted from a mobile state to a fixed state, it is rather cumbersome and has many local parts. The applicant believes that during long-term use, the aging and wear of the parts will affect the overall conversion efficiency of the equipment; second, when the state is converted, the pad is not provided with a buffer mechanism, which causes the staff on the platform to feel obvious shaking, thereby generating certain psychological pressure. Therefore, the technical personnel in this field provide a ship cleaning platform to solve the above-mentioned problems. Utility Model Content
