Before sailing, the actuating cylinder 74 moves the moving teeth 71 outwardly so that the variable gear 38 can be engaged with the clutch gear 24, and how many moving teeth 71 are extended can control the transmission ratio between the upper pulley shaft 26 and the clutch shaft 23.

When navigation is required, the main motor 31 is started to drive the driving shaft 70 to rotate, the driving shaft 70 is rotated to drive the moving shaft 42 to rotate through spline connection, the moving shaft 42 is rotated to drive the left propeller shaft 75 to rotate through the meshing of the moving gear 60 and the left first gear 40, so as to drive the propeller 49 to rotate to drive the hull 11 to navigate to the right, meanwhile, the driving shaft 70 is rotated to drive the upper pulley shaft 26 to rotate through the belt 28, the upper pulley shaft 26 rotates to drive the clutch shaft 23 to rotate through the meshing of the variable gear 38 and the clutch gear 24, the clutch shaft 23 rotates to drive the moving spline shaft 53 to rotate through spline connection, the moving spline shaft 53 rotates to drive the moving spline shaft 51 to rotate through spline connection, the worm shaft 51 rotates to drive the worm wheel shaft 55 to rotate through the worm gear 50 and the worm of the worm wheel 56, the worm wheel shaft 55 rotates to drive the first sliding rod 58 to move to the right through the meshing of the worm wheel 56, the tensioned first torsion spring 79 rotates the rotating shaft 20 to rotate the third gear 22, the third gear 22 rotates to drive the first rack plate 17 to move rightwards through meshing so as to drive the moving shaft 42 to move rightwards through the limit plate 18 so that the moving gear 60 is not meshed with the first gear 40 connected to the left side any more, and the second gear 41 is meshed with the first gear 40 connected to the right side, meanwhile, the third gear 22 rotates to drive the second rack plate 21 to move leftwards through meshing so as to drive the moving spline shaft 53 to move leftwards, the moving spline shaft 53 moves leftwards so that the moving spline shaft 53 is not splined to the clutch shaft 23 any more, i.e., the clutch shaft 23 rotates to not drive the moving spline shaft 53 to rotate, the tensioned second torsion spring 52 drives the worm shaft 51 to rotate so as to drive the worm shaft 55 to rotate through the worm 50 connected with the worm of the worm wheel 56, the worm shaft 55 rotates to drive the first slide bar 58 to move left, the spring 77 is compressed due to the blocking of the catch lever 78.

When the second gear 41 is engaged with the first gear 40 on the right, the blocking plate 64 is no longer blocked by the moving gear 60, the contracted second jacking spring 66 drives the blocking plate 64 to move outwards, the moving shaft 42 rotates to drive the right propeller shaft 75 to rotate through the engagement of the second gear 41 with the first gear 40 on the right, the propeller shaft 75 rotates to drive the second slide bar 32 to move leftwards through the engagement of the propeller shaft 75 with the intermediate gear 36 and the second slide bar 32, the jacking rod 37 is blocked by the second gear 41 to compress the first jacking spring 80 until the force of the contracted first jacking spring 80 can drive the second gear 41 to move leftwards, the second gear 41 moves leftwards and the moving gear 60 is blocked by the moving blocking gear 60, so that the moving gear 60 cannot be engaged with the first gear 40 on the left, and the third jacking spring 61 is compressed, the moving gear 60 is engaged with the fourth gear 15, the sound wave generator 44 transmits sound waves, the moving shaft 42 rotates to drive the threaded shaft 13 to rotate through the meshing of the moving gear 60 and the fourth gear 15, the threaded shaft 13 rotates to drive the sliding block 14 to move leftwards through threaded connection, when the receiving plate 43 receives reflected ultrasonic waves, the motor 47 is started to drive the motor shaft 45 to rotate so as to drive the wire wheel 46 to rotate, the wire wheel 46 rotates to enable the blocking plate 64 to retract into the third spring cavity 65 through pulling the connecting wire 67, the retracted third jacking spring 61 can drive the moving gear 60 to move leftwards so as to enable the moving gear 60 to be meshed with the first gear 40 again, and therefore the main motor 31 can drive the ship body 11 to sail rightwards.

The invention has the beneficial effects that: the invention can detect the depth of the ocean by ultrasonic waves, can measure the depth after sailing for a certain distance, can control the sailing distance by the change of the transmission ratio, can decelerate by starting the propeller on the other side after reaching the specified distance, and can measure the depth after decelerating.

The above description is only an embodiment of the invention, but the scope of the invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the invention. Therefore, the protection scope of the invention should be subject to the protection scope defined by the claims.
