These vessels significantly reduce carbon emissions by using batteries as a power source, aligning with the global trend of energy conservation and emission reduction.

[0003] On the one hand, traditional battery-swapping boats often suffer from poor maneuverability due to a lack of efficient propulsion systems. This is especially true in complex waters or adverse weather conditions, where the vessel's stability and safety are difficult to guarantee. Furthermore, the response speed and precision of existing propulsion systems need improvement to meet the vessel's rapid maneuverability requirements in emergency situations. On the other hand, the electric motor, as the core power component of the battery-swapping boat, directly impacts the overall performance of the vessel due to its operating efficiency and lifespan. However, in existing technologies, the lubrication and cooling systems of electric motors are often poorly designed, failing to adequately meet the lubrication needs of the vessel under various operating conditions. This makes the electric motor prone to overheating and damage during operation, shortening its lifespan and increasing maintenance costs. Utility Model Content

[0031] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] This application discloses a battery swapping vessel, which includes a hull and a side propulsion system, combined with... Figure 1 The side propulsion system includes an oil tank 10, a control cabinet 20, and a side propulsion motor 30, all located at the bow of the battery swapping vessel. The side propulsion motor 30 is connected to a side thrust device 40. The side propulsion motor 30 is electrically connected to the bow side propulsion inverter inside the control cabinet 20. The control cabinet 20 is used to electrically connect to the human-machine interface device of the battery swapping vessel. The connection between the side propulsion motor 30 and the side thrust device 40 is connected to the oil tank 10 through an oil supply pipe 11. The oil tank 10 is used to provide lubricating oil.

[0033] In this way, on the one hand, by arranging the side propulsion system at the bow, the ship's navigation stability is enhanced. The side propulsion drive, consisting of the side propulsion inverter and the side propulsion motor 30 electrically connected, can achieve precise control of the side propulsion drive power, enabling the ship to maneuver flexibly and effectively cope with various navigation needs, especially in complex waters or adverse weather conditions, ensuring safe navigation and improving navigation stability and safety. On the other hand, the oil supply provides a continuous and stable supply of lubricating oil and coolant to the side propulsion motor 30, ensuring that the side propulsion motor 30 receives sufficient lubrication and cooling under various operating conditions. This not only effectively reduces the operating temperature of the motor but also significantly extends its service life, optimizing the motor's operating efficiency and lifespan, thereby improving the overall reliability and economy of the equipment.

[0034] The Bow Thruster Inverter (BT-INV) provides a stable power supply to the Bow Thruster Motor 30 by converting direct current (DC) to alternating current (AC). Through efficient power conversion and precise control, it ensures the stable operation of the Bow Thruster drive. It plays a crucial role in improving ship maneuverability, saving energy, reducing consumption, and extending equipment lifespan.

[0035] The side thruster 40 typically includes a propeller and a gearbox. The output shaft of the side thrust motor 30 is connected to the propeller via the gearbox to provide propulsion on the side of the bow, thus maintaining the stability of the ship.

[0036] It is understandable that the side thrust motor 30 and the side thrust device 40 are installed on both sides of the bow, so that there are two opposing thrusters in the left and right directions to achieve the stability of the ship's navigation.

[0037] The oil tank 10 is a gravity oil tank, which is positioned above the side propulsion motor 30, and the oil supply pipe 11 is connected to the bottom of the oil tank 10. In this way, there is no need for an external power source to use gravity to deliver lubricating oil to the connection between the side propulsion motor 30 and the side propulsion device 40 for lubrication, ensuring transmission efficiency and saving energy.

[0038] The connection between the side propulsion motor 30 and the side propulsion device 40 is connected to the upper part of the oil tank 10 through the exhaust pipe 12. The end of the exhaust pipe 12 away from the oil tank 10 and the end of the oil supply pipe 11 away from the oil tank 10 are horizontally located on both sides of the central axis of the side propulsion motor 30. This design can ensure a stable oil supply to the motor's lubrication system. While the lubricating oil is delivered from the oil tank 10, the air in the system is effectively discharged, ensuring that the lubricating oil can flow smoothly.

[0039] The exhaust pipe 12 is made of stainless steel, and the oil pipe 11 is also made of stainless steel, so as to have good corrosion resistance and improve service life in humid environments.

[0040] The battery swapping vessel also includes a central control box 70 located in the hull and a human-machine interface device (HMI) located in the bridge. The control cabinet 20 and the HMI are both electrically connected to the central control box 70. The HMI can be an operation panel 80, etc. This allows for dual control of the lubrication system and motor rotation via the control cabinet 20. The central control box 70 intelligently controls the control cabinet 20 through preset programs and strategies, and the operation panel 80 in the bridge allows the crew to conveniently and efficiently control the thrusters. This design not only simplifies the operation process but also reduces the risk of human error, improving the vessel's maneuverability and safety.

[0041] The oil pipeline 11 is equipped with a first switch valve 50, and the top of the oil tank 10 has a vent valve 51. The vent valve 51 is electrically connected to the control cabinet 20 so that the driver can open the vent valve 51 through the operation panel 80 and then open the first switch valve 50 to achieve air pressure balance inside and outside the oil tank 10, so that the lubricating oil in the oil tank 10 can be discharged to the oil pipeline 11 under the action of gravity.

[0042] The oil supply pipe 11 is connected to a hand pump 60 and a second switch valve 61 via an emergency pipe. In the event of a malfunction in the electrical control function of the vent valve 51, the oil tank 10 filling port is opened, and the second switch valve 61 is activated so that personnel can operate the hand pump 60 to provide emergency lubricating oil supply, facilitating emergency repairs.

[0043] In summary, this application discloses a side propulsion system and a battery-swapping vessel. On one hand, by arranging the side propulsion system at the bow, the vessel's navigation stability is enhanced. The side propulsion drive, consisting of a side propulsion inverter and a side propulsion motor 30 electrically connected, can achieve precise control of the side propulsion drive power, enabling the vessel to maneuver flexibly and effectively cope with various navigation needs. Especially in complex waters or adverse weather conditions, it ensures safe navigation and improves navigation stability and safety. On the other hand, the system provides a continuous and stable supply of lubricating oil and coolant to the side propulsion motor 30, ensuring that the motor receives sufficient lubrication and cooling under various operating conditions. This not only effectively reduces the motor's operating temperature but also significantly extends its service life, optimizing motor operating efficiency and lifespan, thereby improving the overall reliability and economy of the equipment.

[0045] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
