A slide plate 32 is slidably connected to the top of the compression box 15, a concave hole 34 is machined inside the slide plate 32, and the inside of the air pipe 29 is fixedly connected to the inside of the concave hole 34; Among them, when the ship enters the deep water area, the overall water pressure outside the propeller shaft 1 increases, and the water pressure will enter the inside of the water pressure tank 2 to squeeze the floating plug 5, and the floating plug 5 will push the connecting rod 6 to move upward, and the connecting rod 6 will drive the first rack 8 to move upward, and the first rack 8 will drive the first gear 10 to rotate, and the first gear 10 will drive the second rack 11 to move, and the second rack 11 will drive the connecting bar 13 to move, and the connecting bar 13 will drive the bottom plate 14 to move, and the bottom plate 14 will move along the bottom of the compression box 15, and the bottom hole 31 at the bottom of the compression box 15 can be opened in turn, so as to release the compressed gas inside the compression box 15 in turn, so as to increase the pressure inside the propeller shaft 1, and then keep the pressure inside and outside the propeller shaft 1 balanced; Secondly, when the ship enters the shallow water area, the water pressure outside the propeller shaft 1 decreases, the floating plug 5 inside the water pressure tank 2 will move downward, the floating plug 5 will drive the connecting rod 6 and the first rack 8 to move downward, the first rack 8 will drive the first gear 10 to rotate in the opposite direction, the first gear 10 will drive the second rack 11, the connecting bar 13 and the bottom plate 14 to move, and the bottom hole 31 at the bottom of the compression box 15 will be closed in turn, so that each compression compartment inside the compression box 15 is closed in turn; Furthermore, when the second rack 11 moves, the second rack 11 will push the first piston rod 17 to move, so that one end of the first piston rod 17 moves toward the inside of the oil tank 18, so that the oil inside the oil tank 18 is squeezed into the inside of the oil pipe 19, and the oil enters the inside of the first gear 10 through the oil pipe 19, and squeezes the second piston rod 21 inside the second oil tank 20, so that one end of the second piston rod 21 moves outward, and the second piston rod 21 will drive the third rack 22 to move, and the third rack 22 will drive the second gear 24 to rotate, and the second gear 24 will drive the rotating bearing 25 to rotate, and the rotating bearing 25 will roll along the inside of the sliding frame 26.

The air pipe 29 and the bottom plate 14 move in the same direction, and there is a compression compartment between the air pipe 29 and the bottom plate 14, so that when the bottom plate 14 sequentially closes the multiple compression compartments inside the compression box 15, the air pipe 29 moves to the top of the newly closed compression compartment to sequentially fill the compressed gas, and stops when the standard pressure value is reached; By starting the air compression pump 28, the air compression pump 28 extracts the air inside the propeller shaft 1 and compresses it, so that the pressure inside the propeller shaft 1 is reduced, thereby maintaining a balance with the pressure outside the propeller shaft 1. After the air compression pump 28 compresses the gas, the compressed gas is filled into the compression spacer through the air pipe 29, so that when the pressure inside the propeller shaft 1 needs to be increased later, the pressurization can be released in time; Further, a cavity is processed inside the propeller shaft 1, and a first slide groove 9 is fixedly connected inside the cavity, and one side of the first rack 8 is movably connected inside the first slide groove 9. By providing the first slide groove 9, the first slide groove 9 will limit the movement of the first rack 8 to prevent the first rack 8 from being separated from the first slide groove 9, so that the first rack 8 remains in a stable state when moving; Furthermore, two limiting bars 12 are fixedly connected to both sides of the second rack 11, and the outer portion of the limiting bar 12 is fixedly connected to the inside of the cavity.

At the same time, one side of the bottom plate 14 is embedded in the bottom of the inner cavity of the propeller shaft 1, so that the bottom plate 14 remains stable when it moves, and prevents the bottom plate 14 from being separated from the bottom of the compression box 15. Further, the cavity is fixedly connected with a third slide groove 23, and the third rack 22 is movably connected inside the third slide groove 23. By providing the third slide groove 23, the third slide groove 23 will limit the movement of the third rack 22 to prevent the third rack 22 from being separated from the inside of the third slide groove 23, so that the third rack 22 remains in a stable state when moving; Furthermore, the interior of the cavity is fixedly connected with a sliding frame 26, and the exterior of the rotating bearing 25 is rotatably connected to the interior of the sliding frame 26. By providing the sliding frame 26, the sliding frame 26 will limit the rolling of the rotating bearing 25, and the movement of the rotating bearing 25 will drive the air pipe 29 to move, and the air pipe 29 will drive the concave hole 34 to move; Furthermore, the top of the compression box 15 is fixedly connected to two clamping strips 33, and the concave hole 34 is slidably connected between the two clamping strips 33. The slide plate 32 seals the top of the compression box 15. By providing a sliding frame 26, the concave hole 34 moves along the inside of the clamping strip 33 when moving, thereby preventing the slide plate 32 from being separated from the top of the compression box 15. Furthermore, a plurality of partitions 30 are fixedly connected inside the compression box 15, and a bottom hole 31 is processed at the bottom between each two partitions 30. The bottom of the air pipe 29 is movably connected between the partitions 30, and a compression partition will be formed between the two partitions 30 inside the compression box 15. When the second gear 24 and the rotating bearing 25 rotate, the second gear 24 will drive the air pipe 29 to move laterally, so that the air pipe 29 drives the recessed hole 34 to move, thereby closing the top of the compression box 15 while making one end of the air pipe 29 move in sequence above the compression partition. Working principle: When the overall water pressure outside the propeller shaft 1 increases, the water pressure will enter the interior of the water pressure tank 2 to squeeze the float 5, and the float 5 will push the connecting rod 6 and the first rack 8 to move upward, and the first rack 8 will drive the first gear 10 to rotate, and the first gear 10 will drive the second rack 11, the connecting bar 13 and the bottom plate 14 to move, and the bottom plate 14 will move along the bottom of the compression box 15, and the bottom hole 31 at the bottom of the compression box 15 can be opened in turn, so as to release the compressed gas inside the compression box 15 in turn, so as to increase the pressure inside the propeller shaft 1, and then keep the pressure inside and outside the propeller shaft 1 balanced.
