The propellers are connected to a power source by means of a propeller shaft.

[0003] In the prior art, the following problems still exist in the process of driving a marine vessel by a propeller:

Then, after the two ship propellers 7 located below the second bevel gear 12 rotate 180°, they start to rotate synchronously with the two ship propellers 7 below the first bevel gear 11, which can enable the two ship propellers 7 below the first bevel gear 11 and the second bevel gear 12 to generate propulsion in different directions, so that the hull 1 can easily turn around and avoid the problem of needing to rotate a large bend when turning around.

[0053] like Figure 2 and Figure 7 as well as Figure 8 As shown, the storage mechanism also includes a driving motor 26 fixedly connected to the top of the isolation bin 3, and the two lifting plates 5 are respectively threadedly sleeved on the outer walls of the corresponding screw rods 4. The outer walls of the two screw rods 4 are fixedly sleeved with a second synchronous wheel 28, and the output shaft of the driving motor 26 extends into the isolation bin 3 and is fixedly connected to the first synchronous wheel 27.

In addition, when the lifting plate 5 moves down to extend the ship propeller 7 from the isolation chamber 3, the sealing gasket 43 just extends into the through groove 50, thereby increasing the sealing between the isolation chamber 3 and the through groove 50.

[0062] The effect achieved by the above components is: the driving directions of the two ship propellers 7 under the two lifting plates 5 are opposite, the lifting plates 5 move up and push the arc-shaped push plate 55 to rotate, the arc-shaped push plate 55 pushes the moving box 52 to one side and covers the propeller of the ship propeller 7, and then the propeller of the ship propeller 7 rotates slowly, the second magnet group on one side of the ship propeller 7 cooperates with the first magnet group 66 to drive the disc 65 and the second bevel gear 64 to rotate and the reciprocating screw 59 to rotate, and multiple high-pressure water guns 62 will reciprocate along the reciprocating screw 59, and the high-pressure water guns 62 can clean the surface of the rotating propeller.

[0063] like Figure 4 As shown, a waterproof cover 44 for protecting the dual-axis motor 15 is fixedly connected to the top of one of the lifting plates 5, and a sealing strip 49 is fixedly connected to the bottom of the waterproof cover 44 for increasing the sealing between the waterproof cover 44 and the lifting plate 5. Sealing rings 51 are provided on both sides of the waterproof cover 44 for increasing the sealing between the output shafts on both sides of the dual-axis motor 15 and the waterproof cover 44.

[0064] The effects achieved by the above components are: by providing the waterproof cover 44 , the dual-axis motor 15 can be waterproofed to prevent the dual-axis motor 15 from being affected by moisture. In addition, the sealing strip 49 and the sealing ring 51 can increase the sealing performance of the waterproof cover 44 .

[0065] like Figure 1 and Figure 6 As shown, the pin rod 21 is made of an amorphous alloy, a water pump 45 is fixedly connected to one side of the isolation chamber 3, the liquid inlet fixed sleeve of the water pump 45 is provided with a water inlet pipe 46 extending into the isolation chamber 3, and the liquid outlet fixed sleeve of the water pump 45 is provided with a water outlet pipe 47 extending to one side of the hull 1.

[0066] The effects achieved by the above components are: amorphous alloy is a new material, the amorphous structure is a thermodynamic metastable structure, its local corrosion possibility is lower than that of the crystalline structure, it has good corrosion resistance, and it can be adsorbed by magnets; when the through groove 50 is closed, the seawater in the isolation chamber 3 is then pumped out through the water pump 45 to prevent the seawater in the isolation chamber 3 from corroding the parts inside the isolation chamber 3.

[0067] Working principle: when the hull 1 needs to make a quick U-turn, the dual-axis motor 15 is started, and the two output shafts of the dual-axis motor 15 respectively drive the rotating shaft 14 and the third bevel gear 16 to rotate counterclockwise, and the third bevel gear 16 cooperates with the second bevel gear 12 to drive the worm 10 to rotate, and the worm 10 is meshed with the worm wheel 8, so as to drive the ship propeller 7 to rotate. Since the first bevel gear 11 and the fourth bevel gear 17 have not been meshed before, when the third bevel gear 16 drives the two ship propellers 7 on one side to rotate 180 degrees, the rotating shaft 14 drives the fourth bevel gear 17 to rotate 180 degrees, and the second electromagnet 19 is misaligned with the first strong magnet 18. At this time, the second electromagnet 19 cooperates with the arc-shaped strong magnet 20, and the second electromagnet 19 strongly repels the fourth bevel gear 17 through the arc-shaped strong magnet 20. force, the fourth bevel gear 17 moves to one side and meshes with the first bevel gear 11, the fourth bevel gear 17 drives the pin rod 21 to insert into the pin groove 23, because the pin rod 21 is an amorphous alloy, the third strong magnet 24 generates a magnetic attraction force on the pin rod 21, and then the rotating shaft 14 drives another worm 10 to rotate through the cooperation of the fourth bevel gear 17 and the first bevel gear 11, at this time, the two ship propellers 7 on the other side and the two ship propellers 7 on one side start to rotate synchronously, at this time, the fourth bevel gear 17 and the third bevel gear 16 can rotate counterclockwise by 0°-45° at the same time, which is used to adjust the deflection angle of the ship propeller 7 to one side to make a U-turn, and then the two ship propellers 7 on both sides generate propulsion force in opposite directions, and the hull 1 can be quickly turned around without rotating a large bend, saving the U-turn time;

[0068] When the ship propeller 7 needs to deflect to the other side and turn around, the third bevel gear 16 and the fourth bevel gear 17 return to their initial positions, the second electromagnet 19 corresponds to the position of the arc-shaped strong magnet 20, and then the fourth bevel gear 17 and the third bevel gear 16 rotate clockwise by 0°-45° at the same time. Due to the magnetic force generated by the third strong magnet 24 on the pin 21, the fourth bevel gear 17 can continue to mesh with the first bevel gear 11. At this time, the two ship propellers 7 on both sides can be deflected by 0°-45° in the other direction, so that the hull 1 turns around in the other direction;

[0069] When the U-turn is finished, the rotating shaft 14 and the third bevel gear 16 rotate clockwise, at which time the first strong magnet 18 and the second electromagnet 19 are in corresponding positions, and the magnetic attraction force generated by the second electromagnet 19 and the first strong magnet 18 is much greater than the magnetic attraction force generated by the pin 21 on the pin 21, at which time the fourth bevel gear 17 moves toward the second base 13, and the fourth bevel gear 17 is disengaged from the first bevel gear 11, and then the third bevel gear 16 drives the two ship propellers 7 on one side to return to their original positions;

[0070] Since the ship propeller 7 is in the sea for a long time, the propeller of the ship propeller 7 is covered with dirt, which seriously affects the normal operation of the ship propeller 7 and needs to be cleaned regularly. First, the driving directions of the two ship propellers 7 under the two lifting plates 5 are opposite, and then the two lifting plates 5 move up. When the ship propeller 7 is completely located in the isolation chamber 3, the lifting plate 5 is located above the moving box 52. The lifting plate 5 pushes the arc push plate 55 to rotate through the rectangular plate, and the arc push plate 55 pushes the moving box 52 to one side. At this time, the moving box 52 can cover the propeller of the ship propeller 7. Then the propeller of the ship propeller 7 rotates slowly, and the second magnet group on one side of the ship propeller 7 cooperates with the first magnet group 66 to drive the disc 65 and the second bevel gear 64 to rotate. The second bevel gear 64 drives the reciprocating screw 59 to rotate through the first bevel gear 60. Multiple high-pressure water guns 62 will reciprocate along the reciprocating screw 59, and the high-pressure water guns 62 can clean the surface of the rotating propeller;

[0071] When it is necessary to recover and protect the four ship propellers 7, start the drive motor 26, and the drive motor 26 drives the two screw rods 4 to rotate the screw rods 4 to drive the lifting plate 5 and the connecting cross plate 25 to move upward, and the lifting plate 5 moves the ship propeller 7 into the isolation chamber 3 to prevent the ship propeller 7 from being damaged by marine life and submarine reefs in the outside world. When the connecting cross plate 25 and the nut 31 move to the position of the threaded section 32, due to the cooperation between the nut 31 and the threaded section 32, as the connecting cross plate 25 drives the nut 31 to move upward, the nut 31 drives the rotating rod 30 and the turntable 33 to rotate counterclockwise by 90°, and the turntable 33 pushes the connecting plate 35 and the closing plate 34 to move to one side through the cooperation of the first connecting rod 37 and the second connecting rod 39. At this time, the closing plate 34 can just close the through groove 50, and then the seawater in the isolation chamber 3 is pumped out by the water pump 45.
