[0045] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Instead, these embodiments are provided to make the present invention more thorough and complete and to fully convey the scope of the present invention to those skilled in the art.

[0046] like Figure 1As shown, the present invention provides an on-water wind power storage and exchange device for container battery electric ships, comprising:

[0047] The water platform is arranged in the water, and is arranged close to the position where the ship is sailing away from the shore. The water platform includes a first platform 1 with a surface below the water surface and a second platform 2 with a surface above the water surface;

[0048] Support frame 3, support frame 3 is connected above the first platform 1, and a ship inlet and a ship outlet are formed at opposite ends of the support frame 3 above the first platform 1. A bottom plate 4 is provided inside the support frame 3 above the ship inlet and the ship outlet. The bottom plate 4 is used to place multiple container batteries 5 and is provided with a battery exchange port 6;

[0049] The battery exchange mechanism 7 is arranged at the top of the support frame 3;

[0050] The wind power generation component 8 is arranged on the second platform 2 and is used to charge the container battery 5 on the bottom plate 4 .

[0051] Specifically, in order to solve the problem that the charging and shore-side power exchange methods in the prior art affect the working efficiency of electric ships, the water wind storage and power exchange device for container battery 5 electric ships provided by the present invention has a water platform arranged in the water. The setting position of the water platform is close to the ship's route and away from the shore, laying the foundation for realizing rapid power exchange during the voyage of the electric ship. The first platform 1 of the water platform is arranged underwater, and the second platform 2 is arranged on the water. A power exchange space for accommodating the electric ship is formed between the first platform 1 and the bottom plate 4 of the support frame 3 inside the support frame 3. The electric ship can enter the power exchange space through the ship entrance and stop after entering. The electric ship is stopped in the battery exchange space, and its stability can be maintained by mooring at this time. The battery exchange mechanism 7 on the upper part of the support frame 3 can use the container battery 5 on the bottom plate 4 that is fully charged by the wind power generation component 8 to exchange power for the electric ship, and place the deficient container battery 5 on the bottom plate 4, and continue to be charged by the wind power generation component 8. After the battery is exchanged, the electric ship can sail out from the ship exit and continue sailing. The electric ship does not need to leave the route to go to the shore for battery exchange during navigation, but quickly exchanges power near its route, thereby saving the time wasted in increasing its endurance and improving the working efficiency of the electric ship.

[0052] Furthermore, the wind power generation component 8 may be provided with an energy storage component to store the electric energy generated by the wind power generation so as to ensure the continuity of the electric energy supply.

[0053] In this embodiment, the power exchange mechanism 7 is also powered by the wind power generation component 8.

[0054] Optionally, the above-water platform is fixed in the water.

[0055] Specifically, the water platform is not floating or mobile, but a fixed water platform similar to an offshore exploration or drilling platform. This design makes the position of the water platform fixed, becoming a fixed battery swap station near the route, so that electric ships can swap batteries at a fixed location each time, improving their endurance and effectively improving their battery swap efficiency.

[0056] Optionally, the support frame 3 includes four legs and two layers of frame beams connected to the upper parts of the four legs, the bottom plate 4 is horizontally arranged on the frame beams on the lower layer, and the power exchange mechanism 7 is arranged on the frame beams on the upper layer.

[0057] Specifically, such as Figure 2 As shown, the power exchange mechanism 7 is arranged above the bottom plate 4 and the container battery 5 on the bottom plate 4. The power exchange mechanism 7 passes through the power exchange port 6 on the bottom plate 4 to exchange the power of the container battery 5 of the electric ship.

[0058] Optionally, the battery exchange port 6 is arranged in the middle of the bottom plate 4, and a battery placement area is provided on both sides of the battery exchange port 6.

[0059] Specifically, two battery placement areas are respectively arranged on both sides of the battery exchange port 6. Each time the battery is exchanged, one of the battery placement areas can be set as the placement area for the low-power container battery 5.

The fully charged container battery 5 is placed in the other battery placement area and replaced for the electric ship.

[0060] Optionally, the battery swap mechanism 7 includes:

[0061] Two first beams 9 and two second beams 10, the first beams 9 and the second beams 10 are respectively arranged along an X direction parallel to the ship inlet and toward the ship outlet, and a Y direction perpendicular to the X direction, and the two first beams 9 and the two second beams 10 are connected to form a rectangular frame structure;

[0062] An X-direction moving mechanism 11 is provided between the first beam 9 and the supporting frame 3 and is used to drive the rectangular frame structure to move along the X-direction;

[0063] The battery-swapping trolley 12 is movably arranged above the second beam 10. The battery-swapping trolley 12 includes a trolley frame, a Y-direction moving mechanism 13, a lifting component 14 and a sling 15. The Y-direction moving mechanism 13 is arranged between the trolley frame and the second beam 10, and is used to drive the trolley frame to move along the Y direction. The lifting component 14 is connected to the trolley frame and is used to drive the sling 15 to rise and fall. The sling 15 is used to cooperate with the lifting interface on the top of the container battery 5.

[0064] Specifically, such as Figure 3As shown, the battery exchange mechanism 7 enables the battery exchange carriage 12 to move along the X and Y directions through the setting of the X-direction moving mechanism 11 and the Y-direction moving mechanism 13, so as to complete the replacement and replacement operations of the container battery 5. During the battery exchange process, the lifting component 14 on the battery exchange carriage 12 drives the sling 15 to rise and fall, and the container battery 5 is connected through the sling 15.

[0065] Furthermore, the sling 15 includes a load-bearing plate and clamps arranged on the lower side of the load-bearing plate. The clamps are arranged in pairs. When the clamps are closed, they can be inserted into the lifting interface to lift the container battery 5, and can be separated from the battery pack by opening the clamps after the container battery 5 is put down. The clamps can be driven by electric cylinders or clamp cylinders, etc., which are not limited or elaborated here.

[0066] Optionally, the X-direction moving mechanism 11 includes:

[0067] Two first rails, the two first rails are arranged in parallel on the top of the supporting frame 3;

[0068] First running wheels, which are rotatably arranged on the lower sides of both ends of each first beam 9;

[0071] Two second rails, the two second rails are respectively arranged on the top of the two second beams 10;

[0072] Second traveling wheels, the second traveling wheels are rotatably arranged on the lower sides of both ends of each traveling frame;

[0073] The second driving motor is used to drive the second traveling wheel to rotate.

[0074] Specifically, the X-direction moving mechanism 11 drives the first traveling wheel to rotate through the first driving motor, so that the rectangular frame structure as a whole moves along the X direction, and the Y-direction moving mechanism 13 drives the second traveling wheel to rotate through the second driving motor, so that the traveling frame moves along the Y direction.

[0075] Optionally, the lifting component 14 includes:

[0076] Four winding rollers 16 are rotatably mounted on the traveling frame;

[0077] Four steel wire ropes 17, one end of each steel wire rope 17 is connected to a winding roller 16, and the other ends of the four steel wire ropes 17 are connected to the four corners of the sling 15;

[0078] The third driving motor 18 is used to drive the winding roller 16 to rotate.

[0079] Specifically, such as Figure 4 As shown, the lifting component 14 uses a wire rope 17 to lift the sling 15, and the third drive motor 18 drives the winding roller 16 to rotate and wind the wire rope 17, so as to achieve the lifting of the sling 15. Conversely, releasing the wire rope 17 can achieve the lowering of the sling 15.

[0080] In this embodiment, two third drive motors 18 are provided, and each third drive motor 18 is connected to two winding rollers 16 via a gearbox.

[0081] Optionally, a lifting mechanism is also included, which is arranged on the upper side of the first platform 1. The lifting mechanism includes multiple lifting drive components and a bearing component arranged on the top of the lifting drive component. The bearing component is used to contact the bottom of the electric ship and can lift the electric ship by driving the lifting drive component.

[0082] Specifically, the lifting mechanism can drive the bearing component to contact the bottom of the electric ship and lift it up through the lifting drive component, so as to maintain its stability during the battery replacement process; for different electric ships with different bottom structures, the bearing component can be set with different structures. For electric ships with pointed bottoms, a distributed lifting structure can be adopted, that is, multiple lifting drive components are symmetrically distributed on both sides of the bottom of the electric ship, and the shape of the bearing component is matched with the shape of the bottom. For flat-bottom electric ships specially set up to cooperate with the water wind storage and battery replacement device for container battery 5 electric ships, multiple lifting drive components can be used to connect the same plate-shaped bearing component to lift the electric ship.

[0083] like Figure 5 As shown, the present invention also provides an on-water wind-storage power exchange method for container battery 5 electric ships, using the above-mentioned on-water wind-storage power exchange device for container battery 5 electric ships, the method includes:

[0086] Replacing the battery of the container 5 on the electric ship through the battery replacement mechanism 7;

[0087] The replaced container battery 5 is charged by using the wind power generation component 8 .

[0088] Specifically, the above-water wind storage and battery exchange method for container battery 5 electric ships utilizes the above-mentioned above-mentioned above-mentioned above-mentioned container battery 5 electric ships on the water near the ship's route to exchange batteries for electric ships. When exchanging batteries, there is no need for the electric ship to leave the route and sail to the shore specifically for battery exchange. Instead, during navigation, the electric ship can directly enter the battery exchange space to stop and exchange batteries. After battery exchange, the electric ship can conveniently exit the battery exchange space from the ship's exit and continue to sail along its route, which greatly saves the time wasted by the electric ship to increase its endurance and improves the working efficiency of the electric ship.

[0089] Optionally, when the above-water wind-storage-and-power-exchange device for the container battery 5 electric ship further includes a lifting mechanism, the electric ship parking further includes: lifting the electric ship by the lifting mechanism.

[0090] Specifically, compared with the mooring method, the lifting mechanism will lift the electric ship in the battery exchange space to maintain its stability during battery exchange, which not only saves time but is also more reliable.
