Description

Technical Field

[0001] This utility model relates to the field of new energy water transportation equipment technology, specifically to an electric vessel. Background Technology

[0002] Electric ships are green ships that use electricity as their primary power source, replacing traditional fuel engines. They use batteries to power motors, which in turn drive propellers through transmission devices (such as gearboxes), propelling the ship forward.

[0003] Currently, the power batteries of electric ships are mainly stored in the ship's hold. The ship needs to dock to charge the power batteries. A few cargo ships also use battery energy storage containers to swap batteries by hoisting them ashore.

[0004] However, for most ships in waterways, navigation requires continuity, and each voyage needs to last for a long time. Existing battery swapping equipment usually requires ships to dock midway, which delays time and affects navigation efficiency.

[0005] The relevant technologies mention the use of battery floats and the use of buoyancy to swap batteries for ships, saving battery swapping time. However, the existing battery floats for electric ships are usually attached to the stern of the ship, which affects the flow field at the stern. Summary of the Invention

[0006] In view of this, the present invention provides an improved electric ship, thereby solving or at least alleviating one or more of the above-mentioned problems and other problems existing in the prior art.

[0010] Optionally, the lifting mechanism further includes a crossbeam connecting the upper ends of two adjacent guide rods. The first driving mechanism includes a screw, a gearbox, and a motor extending in the vertical direction. The screw is threadedly connected to the crossbeam. The input end of the gearbox is connected to the motor, and the output end is connected to the screw. The motor drives the screw to rotate, thereby driving the crossbeam to move up and down, and causing the bottom sealing plate to move up and down.

[0011] Optionally, the first driving mechanism is a fluid cylinder, the upper end of which is connected to the hull and the lower end of which is connected to the guide rod or crossbeam.

[0015] Optionally, the electric vessel further includes a second drive mechanism for driving the rotating shaft to rotate. The second drive mechanism includes a motor mounted on the hull and a gearbox connected to the motor. The input end of the gearbox is connected to the motor, and the output end is connected to the rotating shaft.

[0016] In the aforementioned electric vessel, optionally, the receiving slot is located at the stern of the hull, and the side opening faces aft.

[0022] Referring to the accompanying drawings and specific embodiments, the structure, composition, features, and advantages of the electric ship of this utility model will be described below by way of example; however, all descriptions should not be construed as limiting the present utility model in any way.

[0023] For any single technical feature described or implied in the embodiments submitted herein, or any single technical feature shown or implied in the various drawings, the present invention still operates by making any combination or deletion of these technical features or their equivalents without any technical obstacle. Therefore, it should be considered that these further embodiments according to the present invention are also within the scope of the description herein.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. The terms "forward," "rear," etc., indicating orientation or positional relationships are based on the orientation or positional relationships during the navigation of an electric vessel and are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this disclosure.

[0025] See Figures 1 to 3 As shown, the electric ship disclosed in this utility model embodiment includes a hull 1, an electric power device installed on the hull 1, and a battery float 2 for supplying power to the electric power device. The electric power device of the electric ship is usually located at the stern of the hull 1 (not shown in the figure). The electric power device may include a first motor, a first transmission mechanism connected to the first motor, and a propeller (not shown in the figure) connected to the first transmission mechanism. The propeller propels the electric ship.

[0026] The battery float 2 may include a hull and a power battery housed within the hull. The hull may be a sealed hull for protecting the power battery. The hull provides buoyancy and protection for the power battery and isolates the power battery from the outside world, protecting the power battery housed within the hull and preventing external water from entering and affecting the normal operation of the power battery.

[0027] As shown in the figure, the stern of the hull 1 is provided with a receiving tank 3 for accommodating the battery float 2. The receiving tank 3 is located at the waterline of the electric vessel. The receiving tank 3 has a buoyancy position for the battery float 2 to float. The receiving tank 3 also has a bottom opening and a side opening located at the waterline. Both the bottom opening and the side opening are open to the external waters and are connected. The side opening faces the rear and is used for the battery float 2 to float in and out of the buoyancy position through the external waters. When the battery float 2 is replaced, the battery float 2 is floated in and out of the buoyancy position through the side opening by an external towing mechanism. The wire interface is disconnected at the buoyancy position, which can be done by manual wiring or power disconnection.

[0028] The propellers can be installed at the stern of the hull 1, located on both sides of the receiving slot 3, which is situated between the two propellers. Figure 2 The propeller mounting position 8 is shown in the figure.

[0029] The electric vessel also includes a lifting mechanism 4 that is movable in the vertical direction within the receiving tank 3. The lifting mechanism 4 has a bottom sealing plate 41 for supporting the battery float 2 and can also be used to cover the bottom opening of the receiving tank 3.

[0030] like Figure 1 and Figure 3 The bottom sealing plate 41 has a first working position that covers the bottom opening of the receiving groove 3 and a second working position that is exposed outside the receiving groove 3 and located below the receiving groove 3. When the battery float 2 is used to supply power to the electric vessel, the bottom sealing plate 41 is in the first working position (see Figure 1 The bottom sealing plate 41 provides a certain supporting force to the battery float 2, and together with the side wall of the receiving tank 3, stabilizes the battery float 2 in the buoyancy position, preventing the battery float 2 from swaying during electric ship navigation or in large waves. When replacing the battery float 2, the bottom sealing plate 41 is in the second working position (see...). Figure 3 At this point, the battery float 2 sinks to a certain height along with the bottom sealing plate 41. The battery float 2 then floats primarily due to the buoyancy of the water and remains at its buoyancy level. Using an external traction mechanism, the battery float 2 is pulled out of the receiving slot 3, and then the fully charged battery float 2 is pushed back into the receiving slot 3. This makes replacing the battery float 2 convenient and quick. Alternatively, a gripping position can be provided on the side of the battery float 2 for a mechanical claw to grasp, allowing the battery float to be dragged out or pushed into the receiving slot 3.

[0031] See Figure 4The lifting mechanism 4 also includes a plurality of guide rods 42 extending in the vertical direction and spaced circumferentially along the bottom sealing plate 41, and a crossbeam 43 connected to the upper ends of two adjacent guide rods 42. The bottom sealing plate 41 is connected to the bottom of the plurality of guide rods 42. When the bottom sealing plate 41 is in the first working position, the battery float 2 is confined between the plurality of guide rods 42. When the bottom sealing plate 41 is in the second working position, the battery float 2 can float in and out between the plurality of guide rods 42.

[0032] The electric vessel also includes a first drive mechanism for driving the lifting mechanism 4 to move up and down so that the bottom sealing plate 41 switches between a first working position and a second working position.

[0033] The first drive mechanism includes a screw 6 extending in the vertical direction, a second transmission mechanism, and a second motor (not shown in the figure). The input end of the second transmission mechanism is connected to the second motor, and the output end is connected to the upper end of the screw 6. The screw 6 is inserted into the crossbeam 43 and threadedly connected to the crossbeam 43. The second motor drives the screw 6 to rotate, thereby driving the crossbeam 43 to move up and down, and causing the bottom sealing plate 41 to move up and down.

[0034] like Figure 4 In the middle, four guide rods 42 are provided, and two guide rods are connected to the front and two to the rear of the bottom sealing plate 41 respectively. Two crossbeams 43 are provided, connected between the two front guide rods and the two rear guide rods respectively. Each crossbeam 43 is equipped with a screw 6 at both ends, and each screw 6 is equipped with a second motor and a second transmission mechanism to stably lift the bottom sealing plate 41 to move up and down.

[0035] As can be seen from the figure, the stern of the hull 1 also has a bracket 7, which is located above the receiving groove 3. The bracket 7 is provided at the positions corresponding to the guide rods at the front and rear of the bottom sealing plate 41. Each bracket 7 is provided with a sliding groove extending in the vertical direction at the position corresponding to the guide rod 42. The guide rod 42 is slidably disposed in the sliding groove, and the screw 6 is limited between the guide rod 42 and the sliding groove.

[0036] In some alternative embodiments, the first drive mechanism may also be a fluid cylinder, such as a hydraulic cylinder or a pneumatic cylinder, with the upper end of the fluid cylinder connected to the bracket 7 and the lower end connected to the crossbeam or guide rod. Multiple fluid cylinders may be provided, such as one fluid cylinder for each guide rod.

[0037] See also Figure 1 and Figure 3 The electric vessel also includes a side sealing plate assembly 5 movably disposed at the stern of the hull 1. The side sealing plate assembly 5 has a side sealing plate 51 for covering the side opening, further confining the battery float 2 within the receiving slot 3, while greatly improving the flow field at the stern of the hull.

[0038] The side sealing plate assembly 5 also includes a horizontally extending rotating shaft 52 and a connector 53 connecting the rotating shaft 52 and the side sealing plate 51. The rotating shaft 52 is rotatably mounted on the hull 1 around its own axis. Figure 1 As shown, the stern of the hull 1 is provided with bases on both sides above the receiving tank 3, and the two ends of the rotating shaft 52 are respectively rotatably mounted on the bases. The rotating shaft 52 extends along the left and right direction of the hull 1.

[0039] To facilitate the movement of the side sealing plate 51, arc-shaped guide grooves 11 are provided on the opposite side walls of the receiving groove 3 at positions corresponding to the side sealing plate 51. The opposite sides of the side sealing plate 51 can slide along the length direction of the arc-shaped guide groove 11 within the arc-shaped guide groove 11. The side sealing plate 51 is an arc-shaped side sealing plate that arches backward and downward. When the side sealing plate 51 is used to cover the side opening of the receiving groove 3 and the bottom sealing plate 41 is used to cover the bottom opening of the receiving groove 3, the side sealing plate 51 and the bottom sealing plate 41 are used together to cover the receiving groove, while ensuring the streamlined shape of the stern of the hull and avoiding the presence of the receiving groove at the stern of the hull from affecting the flow field at the stern of the hull.

[0040] Optionally, a limiting part 12 is provided at the lower end of each side guide groove 11 to limit the side sealing plate 51 from continuing to rotate downward.

[0041] The electric vessel also includes a second drive mechanism for driving the rotating shaft 52. The second drive mechanism includes a third motor located at the stern of the hull 1 and a third transmission mechanism connected to the third motor (the third motor and transmission mechanism are not shown in the figure). The input end of the third transmission mechanism is connected to the third motor, and the output end is connected to one end of the rotating shaft. The movement of the side sealing plate 51 is driven by the third motor and the third transmission mechanism to rotate the rotating shaft, thereby causing the side sealing plate 51 to rotate. Alternatively, the output end of the third transmission mechanism can be connected to one end of the rotating shaft 52, and the input end can be connected to the motor shaft of the third motor. The third motor drives the third transmission mechanism, thereby driving the rotating shaft 52 to rotate. Both the third motor and the third transmission mechanism are located on the hull. When it is necessary to open the side opening of the receiving slot, the rotating shaft is driven by the motor to rotate, causing the side sealing plate 51 to rotate upwards, opening the side opening of the receiving slot for easy replacement of the battery float. When it is necessary to close, the rotating shaft is driven by the third motor to rotate in the opposite direction, causing the side sealing plate 51 to rotate downwards, thereby closing the side opening.

[0042] In an optional embodiment, the first transmission mechanism, the second transmission mechanism, and the third transmission mechanism can all be gearboxes, and the first motor, the gearbox, the second motor, and the third motor can all be existing motors and gearboxes.

[0043] Optionally, the top of the battery float 2 has an interface (not shown) for electrical connection with the hull 1. The internal power battery of the battery float 2 is connected to this interface via a cable, and this interface is electrically connected (e.g., via a cable) to and supplies power to the electric power unit of the electric vessel. The interface located at the top of the battery float 2 can be easily and effectively waterproofed through a simple mechanical structure, such as by adding a protective cover to its exterior. A cable (e.g., with a plug) can extend from the first motor of the electric power unit of the electric vessel. When the lifting mechanism 4 lifts the battery float 2 to the power supply position, the cable extending from the motor is manually electrically connected to the interface of the battery float 2, or the cable is electrically connected to the interface of the battery float 2 in other ways. When the battery float 2 needs to be replaced, the connection between the cable and the interface of the battery float 2 is disconnected, the lifting mechanism 4 moves downward, the battery float 2 sinks, and then the battery float 2 is pulled out of the receiving slot by the traction mechanism for replacement with a new battery float.

[0044] Regardless of whether the battery float 2 is in the power supply working position (i.e., the bottom sealing plate is in the first working position) or the replacement working position (i.e., the bottom sealing plate is in the second working position), the battery float 2 will float on the water surface, so the interface at the top of the battery float 2 is always above the waterline. Furthermore, when the bottom sealing plate is in the first working position, the battery float 2 is subject to both buoyancy from the water and the supporting force of the bottom sealing plate, and is also confined between the opposite side walls of the groove, maintaining stability in the buoyancy position. When the bottom sealing plate is in the second working position, the battery float 2 sinks a certain height from the power supply working position. At this time, the battery float 2 is mainly subject to buoyancy from the water. With the side sealing plate open, under the action of an external traction mechanism, the battery float 2 can float in and out of the buoyancy position through the side opening of the groove, making battery float facilitating replacement. The containerized batteries do not require complex and cumbersome operations using large lifting equipment. The battery replacement process is completed while the battery floats, making battery swapping convenient and quick. It is suitable for electric vessels that sail long distances, especially for inland and shallow-sea shipping.

[0045] Furthermore, since the bottom and side sealing plates can cover the bottom and side openings of the groove, the stability of the battery float will not be affected even when the electric vessel encounters wind and waves during navigation. The battery float and the hull can be in a relatively stable state, and the wind and waves will not affect the interface of the battery float, and will not be troubled by water pollution. Even when replacing the battery float, the wind and waves in inland waterways and coastal waterways are not enough to reach the surface of the battery float. The interface of the battery float is not polluted by water, and a protective cover can be installed on the interface, which can be removed when making electrical connections.

[0046] Since the second and third motors do not need to be powered continuously, but only when the battery float is being replaced, they can be powered by additional backup batteries or external power sources.

[0047] In addition, in the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to direct connection or indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0048] The above embodiments are only used to illustrate the present utility model, and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
