[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3The utility model provides an embodiment: an electric ship with a speed change device, including a hull 1, which is the main structure of the entire electric ship. It is usually made of high-strength metal materials or composite materials to ensure sufficient strength and stability when traveling in the water. The top of the hull 1 is fixedly connected to a deck 2. The deck 2 is a planar structure on the top of the hull 1, which provides an activity space for crew members and passengers and is also a platform for installing various equipment and facilities. The top of the deck 2 is fixedly connected to a shielding component for cleaning the deck 2. The shielding component includes a cylinder 10. The bottom of the cylinder 10 is fixedly connected to the top of the deck 2, and the driving end of the cylinder 10 is fixed. It is connected with a pushing rod 11, which can be pushed to move by the cylinder 10. The right end of the pushing rod 11 is fixedly connected with a connecting rod 12. When the pushing rod 11 moves, it can drive the connecting rod 12 to move. The front and rear ends of the deck 2 are fixedly connected with a limiting block 3. A slide 4 is provided inside the limiting block 3. The limiting block 3 and the slide 4 can limit the movement of subsequent workpieces. The front and rear ends of the connecting rod 12 are fixedly connected with a moving rod 7. When the connecting rod 12 moves, it can drive the moving rod 7 to move. The bottom of the moving rod 7 is rotatably connected with a pulley 8, and the pulley 8 at the bottom of the moving rod 7 can make the moving rod 7 smoother when moving;

[0033] The outside of the pulley 8 is slidably connected to the inside of the slide 4. The pulley 8 moves inside the slide 4 so that the pulley 8 will not deviate when moving, and at the same time, it can ensure that the motion trajectory is a straight line. The left side of the inside of the slide 4 is fixedly connected to a stabilizing bar 5. The upper and lower sides of the rear end of the stabilizing bar 5 are rotatably connected to the connecting rod 6. The connecting rod 6 can be telescopic and provide stability at the same time. The stabilizing bar 5 is a fixed workpiece that can be used as a fulcrum. The near end of the two groups of connecting rods 6 is fixedly connected to a support rod 9. The support rod 9 can be driven to move by the connecting rod 6. At the same time, the support rod 9 serves as a mutual support between the two groups of connecting rods 6. The hull 1 is designed for a workpiece, the other ends of the two connecting rods 6 are rotatably connected to the upper and lower sides of the rear end of the mobile rod 7, and the connecting rod 6 can be extended and retracted by moving the mobile rod 7. The tops of the stabilizing rod 5 and the mobile rod 7 are fixedly connected with a heavy-duty waterproof canvas 13, which can be stored toward the stabilizing rod 5 when the mobile rod 7 moves. A positioning plate 14 is fixedly connected to the left side of the bottom of the hull 1, and the rear end of the positioning plate 14 is rotatably connected to two angle adjustment sails 15. The positioning plate 14 can provide a fulcrum for the angle adjustment sail 15, and the angle adjustment sail 15 can control the position and direction of the hull 1.

[0034] Reference Figure 1 、 Figure 4 and Figure 5The hull 1 is fixedly connected to a gearbox 16 inside. The gearbox 16 is a workpiece that can provide power for the hull 1. The left side of the gearbox 16 is fixedly connected to a transmission shaft 17. The outside of the transmission shaft 17 is fixedly connected to multiple propellers 18. The power is transmitted to the transmission shaft 17 through the gearbox 16, causing the transmission shaft 17 to rotate, and then it can drive the propellers 18 to rotate at high speed;

[0035] The interior of the hull 1 is fixedly connected with a hydraulic cylinder 19, which can be fixed by the hull 1, and the driving end of the hydraulic cylinder 19 is fixedly connected with a push block 20, which can be pushed to move by the hydraulic cylinder 19. The bottom of the push block 20 is slidably connected to the bottom end of the hull 1, and the push block 20 can move and slide stably. The front and rear ends of the bottom of the push block 20 are both rotatably connected to the bias rod 21. When the push block 20 moves, the two bias rods 21 can be unfolded. The far ends of the two bias rods 21 are rotatably connected to the cross bar 22. When the bias rod 21 moves, the cross bar 22 can be pushed open. The cross bar 22 The left side of the hull 1 is fixedly connected with a roll stabilizer 23, and the cross bar 22 can unfold the roll stabilizer 23 when it is unfolded, so as to prevent the swaying in the water. The front and rear ends of the hull 1 are fixedly connected to the limit plates 24, and the adjacent ends of the two roll stabilizers 23 are in contact with the inside of the limit plates 24. The roll stabilizer 23 can be placed inside the limit plates 24 to achieve the storage effect. A sliding hole 25 is provided inside the limiting plate 24, and the outside of the deflection rod 21 is slidably connected to the inside of the sliding hole 25. The deflection rod 21 can move inside the sliding hole 25, and the sliding hole 25 provides space for the movement of the deflection rod 21.

[0036] Working principle: When the ship docks at the shore, the push rod 11 is first pushed to move by starting the cylinder 10. When the push rod 11 moves, the connecting rod 12 can move. During the movement, the connecting rod 12 can pull the moving rods 7 on both sides to move. Due to the rotating pulley 8 at the top of the moving rod 7, the pulley 8 can slide in the slide 4 opened inside the limiting block 3 to move. Due to the design of the slide 4, the left and right sides of the pulley 8 can be limited to prevent the pulley 8 from deviating while moving. At the same time, when the moving rod 7 moves, the connecting rods 6 on both sides can be pulled and retracted. The function of multiple connecting rods 6 is to enable the moving rod 7 to remain stable while moving, and the function of the support rod 9 is to ensure that the supporting function of the connecting rod 6 will not deviate to both sides when moving. At the same time, the heavy waterproof canvas 13 can be unfolded during movement to prevent bird excrement from falling on the top of the deck 2, ensuring the cleanliness of the hull 1 and the comfort of the staff.

[0037] When the hull 1 is shaken by the impact of wind and waves, the hydraulic cylinder 19 is first started to push the push block 20 to move. When the push block 20 moves, it can drive the deflection rods 21 on both sides to move. When the deflection rods 21 move, they can push the cross bar 22 sliding inside the limit plate 24, thereby achieving the expansion effect. When the cross bar 22 is expanded, it can drive the anti-roll fin 23 to expand. It can dynamically adjust the angle according to actual conditions, effectively reduce the roll of the ship, and improve navigation stability. At the same time, when not in use, pull back the hydraulic cylinder 19 so that the anti-roll fins 23 on both sides can be stored in the limit plate 24.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
