Dish-shaped submersible driven by jet flow and movement method thereof

The invention relates to a disc-shaped submersible driven by jet flow and a movement method of the disc-shaped submersible. The submersible comprises a shell, a vertical driving mechanism and a horizontal driving mechanism. A groove is formed in the middle of the shell, a water inlet channel is formed in the shell, a containing cavity is formed between the water inlet channel and the groove, and two layers of through holes are formed in the water inlet channel; the vertical driving mechanism comprises a central impeller installed in the water inlet channel; the check ring is arranged outside the water inlet channel in a sleeving manner and can rotate relative to the water inlet channel, and two layers of through holes are also formed in the check ring; the water outlet mechanism can open or close the water outlet, and opening and closing of the water outlet are synchronous with rotation of the check ring: when the lower-layer through hole of the water inlet channel is blocked, the water outlet is opened, and
