Description

Technical Field

[0001] The present invention relates to the technical field of water transportation equipment, and in particular to a water power exchange system and a power exchange method. Background Art

[0002] Ships usually use diesel as energy, which is not only costly and noisy, but also easily causes environmental pollution. In recent years, with the development of science and technology, the acquisition and storage of electric energy has become more and more convenient, and the cost of electricity has also decreased. Electric energy has gradually replaced diesel as the power source of ships due to its clean, environmentally friendly and low-cost characteristics.

[0003] Currently, the ships that use electricity as energy are mainly cruise ships on fixed short-distance routes. Their power batteries are stored in the cabin, and the ships need to dock to charge the power batteries. There are also a few cargo ships that use battery storage containers, which continue to supply power to the ships by lifting and replacing the batteries at shore.

[0004] However, for ships in most waters, navigation requires continuity, and each voyage may last for several days and nights. In terms of current battery energy storage costs, if the ship is equipped with energy storage batteries that can meet 24-hour navigation, the battery cost is about 3 times the cost of the ship. In order to save costs, it is necessary to use battery replacement and charging to provide power for the ship's endurance.

[0005] Existing water charging and battery replacement facilities require ships to dock midway, which cannot ensure uninterrupted and continuous sailing of ships, delaying time and affecting sailing efficiency. Especially when lifting and replacing batteries, it is necessary to equip a special dock with lifting operation capabilities. The use conditions are relatively harsh and difficult to popularize.

[0022] With reference to the accompanying drawings and specific embodiments, the structure, composition, characteristics and advantages of the water battery exchange system and the battery exchange method of the present invention will be explained in an exemplary manner below. However, all descriptions should not be used to form any limitations on the present invention.

[0023] In addition, for any single technical feature described or implied in the embodiments mentioned in this document, or any single technical feature displayed or implied in the accompanying drawings, the present invention still allows for continued arbitrary combination or deletion between these technical features (or their equivalents) without any technical obstacles, and thus it should be considered that these more embodiments according to the present invention are also within the scope of the description of this document.

[0024] It should also be noted that the directions or positional relationships indicated by the terms "up", "down", "front", "rear", etc. are based on the directions or positional relationships of the battery swap station, battery pontoon, battery swap boat, and water vehicle of the water battery swap system when they are moored or moving on the water as shown in the accompanying drawings. They are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present disclosure.

[0025] In the description of the present disclosure, “plurality” means at least two, such as two, three or more, etc., unless otherwise clearly and specifically defined.

[0026] Figure 1 It is a schematic diagram of an embodiment of the water power exchange system of the present invention.

[0027] As shown in the figure, the water battery exchange system of the present invention may include a water battery exchange station 1 and a battery exchange ship 3. The battery exchange station 1 may store a battery pontoon 2, and the battery exchange ship 3 is used to exchange power for a water vehicle 4, that is, to replace the battery pontoon for the water vehicle 4. The battery pontoon 2 is used to supply power for the navigation power of the water vehicle, thereby ensuring uninterrupted and continuous navigation of the water vehicle.

[0028] In the battery swap system, the battery swap station 1 provides a buoyancy position, and the battery buoy 2 is located in the buoyancy position for easy docking. Therefore, in the water battery swap system, with the help of the buoyancy of the battery buoy 2 by water, the battery swap ship can quickly and conveniently dock the battery buoy from the buoyancy position, and then replace the battery buoy on the water vehicle.

[0029] The water-based power exchange system can be applied to various water areas. The water-based power exchange system is particularly suitable for inland water areas, such as but not limited to rivers, lakes, etc. Optionally, the water-based power exchange system can also be applied to near-shore waters.

[0030] A large number of battery pods 2 can be stored at the water battery swap station 1 for the water vehicle 4 to swap batteries. For example, these battery pods can be stored in a dedicated storage position at or near the battery swap station 1, and transferred to a buoyancy position when a battery swap is required. Battery pods can also be stored in a floating form in these storage positions. If the battery swap station has enough buoyancy positions for docking, these battery pods can also be stored directly in these buoyancy positions.

[0031] At the water-based battery swap station 1, the battery pods 2 in the storage position or buoyancy position can also be charged. The battery pods 2 with sufficient power in the water-based battery swap station 1 can be connected to the battery swap ship 3, and replaced by the battery swap ship 3 to the water vehicle 4 passing through the water-based battery swap station 1 to provide power for it. The battery pods 2 that need to be charged that are replaced from the water vehicle 4 and transported back by the battery swap ship 3 can be connected to the water-based battery swap station 1 and centrally charged at the water-based battery swap station 1, or temporarily stored at the water-based battery swap station 1 and then centrally transported to an independent charging station for centralized charging.

[0032] As mentioned above, the water battery exchange system may include a water battery exchange station 1 and a battery exchange boat 3 as a complete set of water vehicle battery exchange facilities. In order to achieve the function of rapid battery exchange, a fully charged battery pontoon should be stored at the water battery exchange station 1. The battery exchange boat 3 can pull the battery pontoon from the buoyancy position to float on the water surface and move to the water vehicle for battery exchange.

[0033] The battery swap station can be docked in the waters where the water vehicle is sailing, such as at an appropriate location near the shore or offshore of the sailing waters. As will be described in detail below, the water battery swap station can use the buoyancy of the battery pontoon to enable the staff or the battery swap boat 3 to easily connect the floating battery pontoon with full charge from the battery swap station by towing, and transport it to the water vehicle in the inland waters to replace it with the low-charge battery pontoon of the water vehicle, thereby maintaining the navigation power of the water vehicle and transporting the replaced low-charge battery pontoon from the water to the battery swap station for storage.

[0034] Under normal circumstances, the battery pontoon can be replaced when the water vehicle is moored. Furthermore, in another scenario, the battery pontoon can also be replaced while the water vehicle is moving. At this time, the navigation direction and speed of the battery swapping ship can be the same as the navigation direction and speed of the water vehicle. For example, in order to facilitate battery swapping, the battery swapping ship and the water vehicle can be temporarily fixed together, so that the water vehicle does not need to slow down when swapping batteries and can sail continuously, thereby ensuring its navigation time while saving navigation costs.

[0035] The water vehicle may include various types of ships or even warships, and may be a pure electric water vehicle or a hybrid electric water vehicle. When the water vehicle is powered by the battery pontoon only, in order to ensure the continuous navigation of the water vehicle, when the battery pontoons are replaced one by one, it can be ensured that when the battery pontoons are replaced, other battery pontoons can still continue to provide power for the navigation of the water vehicle.

[0036] Figure 2 The three-dimensional structure diagram of an embodiment of a power exchange station of the water power exchange system of the present invention is shown in the figure. The horizontal dotted line schematically shows the water level when the power exchange station is docked or installed in place.

[0037] from Figure 2 It can be seen from the embodiments that the water battery swap station provides a docking area, an operating area, and a living / office area. In this example, the docking area is half-submerged in the water, and the buoyancy position 11 is located in the docking area for docking the battery pod 2; the operating area 17 is located above the docking area, which is used for the staff to operate the docking of the battery pod 2 and / or the charging of the battery pod 2 during docking; the living / office area 13 is located on the top floor of the water battery swap station 1, which can be used to provide living, office, entertainment and other spaces. In an optional embodiment, the locations of the docking area, operating area 17, and living / office area 13 of the water battery swap station 1 are not limited, and can be adjusted according to the convenience of actual operation. The structure, number and location of the station layers of the water battery swap station are also not limited, and can be increased or decreased according to actual needs.

[0038] When the water battery swap station 1 is moored on the water surface, its docking area is partially located underwater. As shown in the figure, the buoyancy position 11 is located in the docking area, and the buoyancy position 11 is open to the water surface and can be used to dock the battery buoy 2 to be replaced. Specifically, the battery buoy 2 can be floated on the buoyancy position 11 of the battery swap station, and the battery buoy 2 is attached to the buoyancy position 11 of the battery swap station in a detachable manner. That is, when the battery swap ship 3 transports back and stores the battery buoy 2, the battery buoy 2 to be charged can be attached to the buoyancy position 11 of the battery swap station; when the battery swap ship 3 takes away the charged battery buoy 2 from the buoyancy position 11 of the battery swap station, the battery buoy 2 can be detached from the buoyancy position 11 of the battery swap station and towed to the battery swap ship by the staff, or the battery swap station 1 cooperates with the battery swap ship to automatically tow it. Due to the buoyancy, the traction of the battery buoy 2 in the water will be very easy.

[0039] In an optional embodiment, the battery swap station may be provided with a fixing device (not shown) at the buoyancy position 11, through which the battery float 2 can be attached to the buoyancy position 11 of the battery swap station in a detachable manner. The fixing device may, for example, include an electromagnetic adsorption device, which adsorbs and fixes the battery float 2 to the buoyancy position 11 of the battery swap station when the battery float to be charged is transported back and stored; when the charged battery float 2 is removed from the buoyancy position 11, the electromagnetic adsorption device is demagnetized and detached from the adsorption of the battery float 2. Optionally, the fixing device may also include an easily detachable hook, rope, etc.

[0040] from Figure 2 It can be seen that in order to accommodate the battery swapping ship, the water battery swapping station 1 is optionally provided with an anchor 18, which is used to temporarily anchor the battery swapping ship 3 to the water battery swapping station 1, so as to facilitate the battery swapping ship 3 to smoothly connect to the battery buoy 2 at the battery swapping station 1. In an optional embodiment, electromagnetic adsorption anchoring can also be used.

[0041] In the illustrated example, eight buoyancy positions 11 are provided in the docking area of ​​the battery swap station, of which six on the left are shown to store battery buoys 2, and two on the right are vacant, and every two buoyancy positions 11 constitute a docking position 12, that is, the water-based battery swap station 1 provides a total of four docking positions. Each docking position can accommodate a battery swap ship 3, which docks the battery buoys 2 in two adjacent buoyancy positions 11 and tows them away or stores them in the water-based battery swap station with the help of the buoyancy of the water surface.

[0042] In an optional embodiment, the number of buoyancy positions 11 constituting a docking position 12 is not limited, and one or more may be provided according to actual needs. Furthermore, the number of the docking positions 12 in the docking area of ​​the battery swap station is not limited, and may be provided as one or more according to actual needs. Optionally, the bottom of the docking position 12 may have a bottom plate as shown in the figure, or may not have a bottom plate, so that the battery buoy 2 floats directly in the water. In the case of having a bottom plate, the battery buoy can float in the water without contacting the bottom plate; or it may contact the bottom plate, in which case the buoyancy can also reduce the force of the traction battery buoy.

[0043] Optionally, a limiting device (not shown in the figure) can also be set on the side of each buoyancy position 11 of the battery swap station. When the battery float 2 floats on the buoyancy position 11 of the battery swap station, the limiting device can limit the movable position of the battery float 2, further preventing the battery float 2 in each docking position from colliding with each other and causing damage, and the limiting device can also separate each docking position 12.

[0044] Optionally, the above-mentioned limiting device can be as follows Figure 2The barrier bar shown may also be a partition or a rope, etc., as long as it can limit the movable position of the battery pontoon 2 when it floats. In an optional embodiment, a limit device may also be provided before and after each buoyancy position 11 of the battery swap station and / or each docking position 12 to limit the movable range of the battery pontoon 2, so as to make it easier and faster to store or take out the battery pontoon 2.

[0045] according to Figure 2 In an embodiment, optionally, the buoyancy position 11 may also be provided with a buoyancy regulating device 14, which can adjust the draft of the docking position 12 of the buoyancy position 11 of the battery swap station by discharging water, and cooperate with a large number of battery floating tanks to compensate for the possible impact on the draft of the buoyancy position 11 of the battery swap station, when the draft deviates from the normal water level line.

[0046] The buoyancy regulating device 14 may be Figure 2 As shown, the buoyancy regulating device 14 is arranged on both sides of the docking position 12, that is, the buoyancy regulating device 14 balances and adjusts the buoyancy of the water battery swap station 1 from both sides to adjust the draft of the docking position 12, so as to facilitate the battery swap boat 3 to dock the battery buoyancy chamber 2. In an optional embodiment, the position of the buoyancy regulating device 14 is not limited, and it can also be arranged in the middle part of the docking position 12, and the docking position 12 is distributed on both sides of the buoyancy regulating device 14. For example, the buoyancy of the water battery swap station 1 can be more conveniently adjusted along the center of gravity of the water battery swap station 1, and then the draft of the docking position 12 can be adjusted, so as to facilitate the battery swap boat 3 to dock and replace the battery buoyancy chamber 2.

[0047] Furthermore, the buoyancy adjustment device 14 can adjust the draft depth of the docking position 12 of the battery swap station buoyancy position 11 to match the draft depth of the battery swap ship buoyancy position 31 of the battery swap ship 3, so that the battery floating cabin 2 can be translated between the buoyancy position 11 of the battery swap station and the buoyancy position 31 of the battery swap ship, making it more convenient to replace the battery floating cabin 2.

[0048] In an optional embodiment, the buoyancy adjustment device 14 may include but is not limited to a pressurized water tank, the adjustable buoyancy of which may be greater than the weight of the battery floating tank 2 stored in the docking position 12, so that the pressurized water tank can adjust the buoyancy of the water battery swap station 1 by filling or discharging water to adjust the draft depth of the buoyancy position 11 of the battery swap station, thereby facilitating the docking of the battery floating tank 2.

[0049] In other embodiments, the docking position 12 and the buoyancy position 11 can be located inside the water-based battery swap station 1 as shown in the figure, or can be set outside the water-based battery swap station 1, for example, set in the open air on the side of the water-based battery swap station, and the position of the docking position 12 can be adjusted by the buoyancy adjustment device 14 to match the buoyancy position 31 of the battery swap ship, so as to facilitate the replacement of the battery buoyancy tank 2. Regardless of whether the docking position 12 and the buoyancy position 11 are inside or outside the water-based battery swap station 1, collision protection can be provided on the side to protect the battery buoyancy tank.

[0050] according to Figure 2 In the embodiment, the water-based power swap station 1 is provided with an operation area 17, in which the staff can monitor the operation of the water-based power swap station 1, control the power swapping of the water-based power swap station 1 or monitor the automatic power swapping of the power swapping station 1, and the staff can also perform maintenance and other operations on the facilities and equipment of the water-based power swap station 1. The operation area 17 is set in a layer structure close to the buoyancy position 2, which is convenient for the staff to quickly and closely handle the power swapping of the power swapping station 1. In an optional embodiment, the location of the operation area 17 is not limited and can be adjusted according to the convenience of actual operation.

[0051] from Figure 2 It can also be seen from the embodiments that living, office, rest, entertainment and other facilities for the staff can be set up in the living / office area of ​​the water battery swap station 1. A substation facility 15 can also be installed on this layer. The substation facility 15 adjusts the voltage, current, frequency, etc. of the introduced power supply, and modulates it into a power supply that can be used to charge the battery pod 2 through the charging facility 16. The power supply is introduced into the buoyancy position 11 to charge the battery pod 2 stored therein. The charging facility 16 can be a charging gun 19 connected by a cable, and a charging gun 19 can be provided at each buoyancy position, and the charging gun 19 charges the battery pod 2 stored in the buoyancy position 11. In an optional embodiment, the installation location of the substation facility 15 and the charging facility 16 is not limited, as long as the introduced power supply can be modulated into a rechargeable power supply and introduced into the docking position 12.

[0052] In actual use, the water-based power exchange station 1 can be used along the water vehicle 4 (such as Figure 5 Multiple ones are arranged on the waterway (as shown) to facilitate the water vehicle 4 to change power when passing through the water power station 1, thereby saving transportation costs while maintaining the continuous navigation of the water vehicle 4 and ensuring navigation time.

[0053] It should be noted that the style of the floating exchange station 1 is not limited and can be Figure 2In the embodiment, it can also be a semi-submersible pontoon, which is suitable for docking in inland waters offshore or near the shore, that is, the semi-submersible pontoon can be conveniently set up in multiple numbers along the coast of the navigation waters of the water vehicle 4, and cooperate with its matching battery exchange ship 3 to facilitate the battery exchange of the water vehicle 4 on its waterway.

[0054] Figure 3 It is a schematic diagram of the three-dimensional structure of an embodiment of a battery exchange vessel of the water battery exchange system of the present invention.

[0055] The battery exchange vessel 3 of the present invention is used to connect the battery pod 2 from the buoyancy position 11 of the water battery exchange station 1, thereby towing the battery pod 2 to the water vehicle 4 for replacement, thereby realizing battery replacement for the water vehicle 4.

[0056] According to the illustrated example, the battery swap ship 3 may have a battery buoyancy position 31, which is open to the water surface, and the battery buoyancy 2 may float on the buoyancy position 31. During the transportation of the battery swap ship 3, the battery buoyancy 2 follows the battery swap ship 3 in the battery swap ship buoyancy position 31. In an optional embodiment, the battery swap ship may not be provided with a buoyancy position, but directly carry the battery buoyancy.

[0057] In some embodiments, the side of the buoyancy position 31 of the battery exchange ship may be provided with a limit device, such as Figure 3 As shown in the ship's side, when the battery pontoon 2 floats on the buoyancy position 31 of the battery swapping ship, the limiting device can limit the movable position of the battery pontoon 2, and further prevent the battery pontoons 2 in the buoyancy position 31 of the battery swapping ship from colliding with each other and causing damage. In some embodiments, the battery swapping ship can also be configured to be bottomless and / or without a limit device.

[0058] Optionally, the limiting device may also be a barrier bar, a partition or a rope, etc., as long as it can limit the active position of the battery pontoon 2 and prevent collision when the battery pontoon 2 is displaced left and right. In an optional embodiment, the limiting device may be set on one side of the buoyancy position 31 of the battery swapping ship, or on both sides of the buoyancy position 31 of the battery swapping ship; limiting devices may also be set before and after each buoyancy position 31 of the battery swapping ship to limit the range of movement of the battery pontoon 2, so that in order to easily and quickly store or remove the battery pontoon 2, some limiting devices can be operated to cancel the limit.

[0059] In another embodiment, the battery swap ship 3 may also have a buoyancy adjustment device (not shown in the figure), for example, it can be a pressurized water tank inside the ship's side on both sides. The buoyancy adjustment device can adjust the buoyancy of the battery swap ship 3 to adjust the draft depth of the buoyancy position 31 of the battery swap ship, thereby facilitating the docking of the battery floating tank 2.

[0060] Furthermore, in the actual battery swap process, the draft of the battery swap ship and the draft of the battery swap station can be adjusted by the buoyancy adjustment device to match the two, so that the battery buoyancy tank 2 can be translated between the buoyancy position 31 of the battery swap ship and the buoyancy position 11 of the battery swap station, making it more convenient to replace the battery buoyancy tank 2. Similarly, the buoyancy adjustment device can also adjust the draft of the battery swap ship and the draft of the water vehicle (see Figure 5 The draft depth of the battery buoyancy chamber 2 is determined by adjusting the draft depth of the battery buoyancy chamber 2 as shown in the figure, so that the two are matched, so that the battery buoyancy chamber 2 can be translated between the buoyancy position 31 of the battery exchange ship and the buoyancy position 47 of the water vehicle, making the replacement of the battery buoyancy chamber 2 more convenient.

[0061] In an optional embodiment, the buoyancy adjustment device may include but is not limited to a water pressure tank, which can adjust the buoyancy of the battery swap ship 3 by filling or discharging water, thereby adjusting the draft of the battery swap ship.

[0062] Figure 4 It is a schematic diagram of the three-dimensional structure of an embodiment of a battery floating compartment of the water power exchange system of the present invention.

[0063] from Figure 4 As can be seen from the embodiment, the battery buoy 2 has a hull 21, in which a power battery (not shown) is placed, and the power battery is used to provide power for the navigation power of the water vehicle 4. When replacing the battery, the battery buoy can be towed between different positions on the water surface by a battery-changing boat.

[0064] In the illustrated example, the power battery is completely enclosed in the cabin 21 to protect the power battery placed therein and prevent external collision from damaging the power battery. In addition, when the battery floating cabin 1 floats on the water, the cabin 21 can provide waterproof protection and temperature regulation for the power battery to prevent the entry of external water from affecting the normal operation of the power battery, and can be used to adjust and keep the battery floating cabin 1 floating on the water surface and keep the battery floating cabin 1 within the set operating temperature range. The cabin 21 can be independent of the housing of the power battery, or integrally formed in the housing of the power battery.

[0065] In an optional embodiment, the cabin 21 may also partially cover the power battery 11 , and the exposed part of the power battery 11 may be entirely located above the waterline of the battery buoyancy cabin 1 to prevent external water from entering and affecting the normal operation of the power battery 11 .

[0066] Combination Figure 2 and Figure 3 It can be seen that when the battery floating cabin 2 is located at the buoyancy position 11 of the water battery swap station and the buoyancy position 31 of the battery swap ship, the water in the buoyancy position 11 of the water battery swap station and the buoyancy position 31 of the battery swap ship can provide buoyancy for the battery floating cabin 2, so the battery floating cabin 2 can be conveniently moved by manual operation with the help of buoyancy only by traction.

[0067] In different embodiments, the battery buoyancy compartment 2 may also be provided with a buoyancy regulating device, which can adjust the draft of the battery buoyancy compartment 2 , thereby facilitating the docking of the battery buoyancy compartment 2 .

[0068] Furthermore, the buoyancy adjustment device can be used to adjust the battery buoyancy compartment 2 and the water-based battery swap station (such as Figure 2 Similarly, the buoyancy adjustment device can be used to adjust the draft depth of the battery buoyancy compartment 2 and the battery exchange ship (as shown in FIG. Figure 3 The draft depth of the battery pontoon 2 is matched with the draft depth of the battery pontoon 2 as shown, so as to facilitate the quick replacement of the battery pontoon 2 at the buoyancy position 11 of the water battery exchange station and the buoyancy position 31 of the battery exchange ship.

[0069] In an optional embodiment, the buoyancy adjustment device may include but is not limited to a pressurized water tank, the adjustable buoyancy of which is greater than the weight of the battery float tank 2, so that the pressurized water tank can adjust the buoyancy and draft of the battery float tank 2 by taking in or out water, thereby facilitating the replacement of the battery float tank 2.

[0070] from Figure 4 It can also be seen from the embodiment that the battery buoy 2 also has a power interface 22, which can be connected to the charging facility 16 of the water charging station 1 for charging. The power interface 22 can also be connected to the water vehicle 4 to provide power and electrical energy for the water vehicle 4.

[0071] Figure 5 It is a schematic diagram of the three-dimensional structure of an embodiment of the water vehicle of the water power exchange system of the present invention.

[0072] The water-based power exchange system of the present invention may further include a water vehicle 4. The water vehicle 4 may be an electric boat or a hybrid ship, which may have a built-in or external battery buoyancy position, so that the battery buoyancy position may be built-in or external, and the battery buoyancy position may be attached to the water vehicle at the buoyancy position. In the case of a built-in position, the buoyancy position may be located between the two side thrusters at the tail of the water vehicle.

[0073] like Figure 5 As shown, in this example, the water vehicle 4 is composed of a split carrying cabin 41 and a power cabin 42, and the carrying cabin 41 and the power cabin 42 are movably connected, that is, the carrying cabin 41 and the power cabin 42 have independent drafts, and the draft change of the carrying cabin 41 does not affect the draft of the power cabin 42. The carrying cabin 41 can be, but is not limited to, a cruise ship, a passenger ship, a cargo ship, a barge, a yacht, etc., and can carry people, goods, etc. on the water.

[0074] The power cabin 42 may be provided with a buoyancy position 47 open to the water surface, the battery buoyancy position 2 may be attached to the buoyancy position 47, and the battery buoyancy position 2 may float on the buoyancy position 47, and the battery buoyancy position 2 may be conveniently towed and replaced by means of the water surface at the buoyancy position 47. Specifically, the buoyancy position 47 may be inside or outside the electric boat, so that the battery buoyancy position may be built-in or external.

[0075] Optionally, the power compartment 42 of the water vehicle 4 may also have a buoyancy regulating device, which can change the draft of the power compartment 42 by adjusting the buoyancy of the power compartment 42 of the water vehicle 4, thereby facilitating the replacement of the battery floating compartment 2.

[0076] Furthermore, the draft of the water vehicle can be adjusted to match the battery swapping ship, so that the battery can be easily and quickly swapped between the buoyancy position 31 of the battery swapping ship and the buoyancy position 47 of the water vehicle.

[0077] In an optional embodiment, the buoyancy regulating device may include but is not limited to a pressure tank, which can adjust the draft depth of the buoyancy position 47 of the water vehicle by filling or discharging water.

[0078] from Figure 5 It can also be seen from the embodiment that the power cabin 42 can be equipped with two battery buoyancy tanks 2. Specifically, in the illustrated example, the carrier cabin and the power cabin of the water vehicle are separately arranged, and a buoyancy position is arranged between the two thrusters at the rear of the power cabin, and the battery buoyancy tank is attached to the buoyancy position. The power cabin can push the carrier cabin at the rear of the carrier cabin, and can also tow the carrier cabin at the front of the carrier cabin. The driving and operating room of the water vehicle can be located in the carrier cabin or the power cabin; when the driving and operating room is located in the carrier cabin, the power device of the power cabin can be controlled through a data connection to control the power cabin to push the carrier cabin.

[0079] In actual use, the number of battery pontoons 2 installed in the power cabin 42 is not limited and can be adjusted according to actual conditions. When the carrier cabin 41 itself has power for navigation, the power cabin 42 can only install one battery pontoon 2 as auxiliary power; when the carrier cabin 41 has a large tonnage, the power cabin 42 can be equipped with multiple battery pontoons 2 to provide sufficient navigation power.

[0080] When the water vehicle 4 is powered by the battery pontoons 2 of the power cabin 42 only, in order to ensure the continuous navigation of the water vehicle 4, when the battery pontoons are replaced, at least one battery pontoon can be guaranteed to continue to provide power for the navigation of the water vehicle.

[0081] The present invention also provides a battery replacement method, which uses the water battery replacement system of any one of the aforementioned embodiments to replace the battery of the water vehicle, and the method comprises the following steps: the battery replacement ship uses buoyancy to connect the battery floating cabin between the battery replacement station and / or the water vehicle. Therefore, the battery replacement method also has the advantages of the corresponding traction convenience of the aforementioned water battery replacement system. In an optional embodiment, the method may also include the following steps: arranging multiple water battery replacement stations 1 on the operating channel of the water vehicle 4 to provide battery replacement services for the water vehicle.

[0082] When the water vehicle 4 needs to change batteries, the battery-changing boat 3 can conveniently and quickly connect the fully charged battery pontoon 2 from the buoyancy position 11 of the water-based battery-changing station 1 with the help of the buoyancy of water. Optionally, the buoyancy adjustment device of the water-based battery-changing station 1 and / or the battery-changing boat 3 can also be adjusted to make the draft of the battery-changing station match the draft of the battery-changing boat, so as to facilitate the quick replacement of the battery pontoon 2.

[0083] The battery swapping vessel 3 transports the fully charged battery pod 2 to the water vehicle 4 in the navigation area, and uses the buoyancy to conveniently and quickly replace the low-charged battery pod 2 of the water vehicle 4. Optionally, the buoyancy adjustment device of the battery swapping vessel 3 can be adjusted so that the draft of the buoyancy position 31 of the battery swapping vessel matches the buoyancy position 47 of the water vehicle, thereby facilitating the quick replacement of the battery pod 2.

[0084] During the mobile battery exchange, the speed of the battery exchange boat 3 can be kept the same as the navigation speed and direction of the water vehicle 4, that is, the water vehicle 4 does not need to slow down during the battery exchange and can continue to sail, thereby maintaining the navigation power of the water vehicle and conveniently completing the battery exchange of the water vehicle battery pontoon, ensuring its navigation time and saving navigation costs. The battery exchange can also be carried out after the water vehicle is moored.

[0085] The battery swapping vessel 3 transports the replaced low-power battery pontoon 2 to the floating battery swapping station 1, and uses buoyancy to connect the low-power battery pontoon 2 to the floating battery swapping station buoyancy position 11 of the floating battery swapping station 1. Optionally, the buoyancy adjustment device of the floating battery swapping station 1 and / or the battery swapping vessel 3 can be adjusted to make the draft of the battery swapping station match the draft of the battery swapping vessel, so as to facilitate the quick connection of the battery pontoon 2.

[0086] Optionally, the low-battery floating cabin 2 can be connected to a charging gun 19 located at the buoyancy position 11 of the battery swap station for charging, and after being fully charged, it can be used for subsequent battery swapping by the water vehicle 4 .

[0087] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the scope of the present invention.
