Description

Water power conversion system and power conversion method thereof

Technical Field

The invention relates to the technical field of water traffic equipment, in particular to a water power conversion system and a power conversion method.

Background

The ship usually uses diesel oil as energy, which not only has high cost and high noise, but also is easy to cause environmental pollution. In recent years, along with the development of technology, the acquisition and storage of electric power are more and more convenient, the electricity cost is also reduced, and the electric power is gradually replaced by diesel oil as the power source of the ship due to the characteristics of cleanness, environmental protection, low cost and the like.

At present, a ship using electric power as an energy source is mainly a pleasure boat for fixing a short-distance route, a power battery of the pleasure boat is fixedly stored in a cabin, the power battery is required to be charged by the ship by being on shore, and a few freight ships adopt battery energy storage containers to continuously supply power to the ship in a mode of hoisting and replacing the power by being on shore.

However, for a ship in most waters, there is a continuous requirement for sailing, each sailing may last for several days and several nights, and regarding the current battery energy storage cost, if the ship is provided with an energy storage battery which meets 24 hours sailing, the battery cost is about 3 times or more of the cost of the ship, and in order to save the cost, the power of the ship needs to be continued by adopting a power-exchanging and charging mode.

The existing water charging and electricity changing facilities need to berth in the middle of the ship, so that uninterrupted continuous sailing of the ship cannot be ensured, the time is delayed, and the sailing timeliness is affected. In particular, a special wharf with hoisting operation capability is required to be equipped for hoisting and replacing electricity, the service condition is severe, and the popularization and the realization are difficult.

The structure, composition, characteristics, advantages and the like of the water power conversion system and the power conversion method thereof of the present invention will be described below by way of example with reference to the accompanying drawings and specific embodiments, however, all descriptions should not be construed as limiting the present invention in any way.

Furthermore, to the extent that any individual feature described or implied in the embodiments set forth herein, or any individual feature shown or implied in the figures, the invention still allows any combination or deletion of such features (or equivalents thereof) without any technical hurdle, and further embodiments according to the invention are considered to be within the scope of the disclosure herein.

It should also be noted that the azimuth or positional relationship indicated by the terms "upper", "lower", "front", "rear", etc. are those based on the power station, battery compartment, power boat, water carrier of the water power system shown in the drawings, i.e., when moored or traveling on water, are merely for convenience of description of the present disclosure and to simplify the description, and are not indicative or implying that the apparatus or element referred to must have a specific azimuth, be configured and operated in a specific azimuth, and therefore should not be construed as limiting the present disclosure.

In the description of the present disclosure, the meaning of "a plurality" is at least two, such as two, three or more, etc., unless explicitly defined otherwise.

FIG. 1 is a schematic diagram of one embodiment of a water power conversion system of the present invention.

As shown in the figure, the water power conversion system of the invention can comprise a water power conversion station 1 and a power conversion ship 3, wherein a battery floating cabin 2 can be stored in the power conversion station 1, and the power conversion ship 3 is used for converting power for a water carrier 4, namely, the water carrier 4 is used for replacing the battery floating cabin. The battery buoyancy module 2 is used for supplying power for the navigation power of the water-borne vehicle, so that the water-borne vehicle can navigate continuously.

In this power exchange system, the power exchange station 1 provides a buoyancy position in which the battery buoyancy module 2 is located for ease of docking. Thus, in the above-water power exchange system, the power exchange ship can quickly and conveniently dock the battery buoyancy module from the buoyancy position by means of the buoyancy of the water to the battery buoyancy module 2, and further exchange the battery buoyancy module on the water-borne carrier.

The water power conversion system can be applied to various waters. The water power conversion system is particularly suitable for inland water areas, such as, but not limited to, rivers, lakes, and the like. Alternatively, the above water power exchanging system may be applied to the offshore surface.

A plurality of battery buoyancy tanks 2 can be stored at the water power exchange station 1 to exchange power with the water supply upper carrier 4. For example, these battery pods may be stored in dedicated storage locations at or near the power exchange station 1, which are transferred to buoyancy locations when a power exchange is required. The battery buoyancy modules can also be stored in a floating form in the storage bits. If the station has enough buoyancy bits for docking, the battery buoyancy tanks may also be stored directly in the buoyancy bits.

The battery buoyancy tanks 2 in the storage or buoyancy locations may also be charged at the water power station 1. The battery buoyancy module 2 with sufficient electric quantity in the water power exchange station 1 can be connected to the power exchange ship 3 and is exchanged to the water carrier 4 passing through the water power exchange station 1 through the power exchange ship 3 to supply power for the water power exchange station 1. The battery buoyancy module 2 to be charged, which is replaced from the water carrier 4 and returned by the electricity replacing ship 3, can be connected to the water electricity replacing station 1 and is subjected to concentrated charging at the water electricity replacing station 1, or temporarily stored in the water electricity replacing station 1 and then is subjected to concentrated charging by being transferred to an independent charging station.

As mentioned above, the water power exchanging system may comprise the water power exchanging station 1 and the power exchanging ship 3 as a complete water carrier power exchanging facility. In order to realize the function of quick power change, a charged battery floating cabin should be stored at the water power change station 1. The electricity changing ship 3 can start to pull the battery buoyancy cabin to float on the water surface from the buoyancy position and move to the water carrier for electricity changing.

The power exchange station may be docked in place on the water carrier in a body of water, such as offshore or near-shore in the body of water. As will be described in detail below, the above-water power exchange station can enable a worker or a power exchange ship 3 to conveniently dock a floating full-capacity battery buoyancy module from the power exchange station by traction, transport the battery buoyancy module to a water carrier in inland water, exchange the battery buoyancy module with a low-capacity battery buoyancy module of the water carrier, thereby maintaining the sailing power of the water carrier, and transport the exchanged low-capacity battery buoyancy module from water to the power exchange station for storage.

In general, the battery buoyancy module may be replaced with the water carrier moored. Further, in another scenario, the battery pod may also be replaced while the water carrier is traveling. At this time, the navigation direction and speed of the power conversion ship can be kept the same as those of the water carrier, for example, the power conversion ship and the water carrier can be temporarily fixed together for convenient power conversion, so that the water carrier does not need to be decelerated during power conversion and can continuously navigate, thereby ensuring the navigation timeliness and saving the navigation cost.

The water-borne carrier can comprise various ships, even ships, and the like, and can be a pure water-borne carrier or an oil-electricity hybrid power water-borne carrier. When the water-borne carrier is only provided with the navigation power supply by the battery buoyancy tanks, in order to ensure continuous navigation of the water-borne carrier, when the battery buoyancy tanks are replaced one by one, the other battery buoyancy tanks can still provide power for the navigation power of the water-borne carrier continuously.

Fig. 2 is a schematic perspective view of an embodiment of a power exchange station of the water power exchange system of the present invention. The water line is schematically shown in horizontal dashed lines when the station is docked or installed in place.

As can be seen from the embodiment of fig. 2, the water power station provides a docking area, an operation area, a living/office area. In this example, in the semi-potential water of the docking area, the buoyancy station 11 is located in the docking area for docking of the battery buoyancy module 2, the operation area 17 is located above the docking area for the staff to operate the docking of the battery buoyancy module 2 and/or to operate the charging of the battery buoyancy module 2 when docked, and the living/working area 13 is located on the top layer of the water power exchange station 1, which can be used to provide living, working, entertainment and other spaces. In an alternative embodiment, the connection area, the operation area 17 and the living/office area 13 of the water power exchange station 1 are not limited, and can be adjusted according to the convenience of actual operation. The structure, the number and the positions of the station layers of the water power exchange station are not limited, and can be increased or decreased according to actual requirements.

When the above-water power exchange station 1 is moored on the water surface, the docking area portion thereof is positioned under water. As shown in the figure, the buoyancy place 11 is located in the docking area, the buoyancy place 11 being open to the water surface, available for docking the battery buoyancy module 2 to be replaced. In particular, the battery buoyancy module 2 may float at the station buoyancy station 11, the battery buoyancy module 2 being detachably attached to the station buoyancy station 11. That is, when the battery floating capsule 2 to be charged is attached to the battery floating capsule 11 when the power exchange ship 3 is transported back and stored, and when the battery floating capsule 2 after the charging is taken away from the battery floating capsule 11 by the power exchange ship 3, the battery floating capsule 2 can be separated from the battery floating capsule 11 and pulled to the power exchange ship by a worker or automatically pulled by the power exchange ship 1 in cooperation with the power exchange ship, the traction of the battery floating capsule 2 in water is very easy due to the buoyancy effect.

In an alternative embodiment the exchange station may be provided with fixing means (not shown) at the buoyancy station 11, by means of which the battery buoyancy module 2 can be attached in a releasable manner to the exchange station buoyancy station 11. The fixing means may for example comprise electromagnetic adsorption means which, when the battery compartment to be charged is transported back and stored, adsorbs the battery compartment 2 to the buoyancy station 11 of the power exchange station, and when the charged battery compartment 2 is removed from the buoyancy station 11, demagnetizes the adsorption of the battery compartment 2. Alternatively, the securing means may also comprise a quick release hook, rope or the like.

As can be seen from fig. 2, the water power plant 1 is optionally provided with an anchor 18 for temporarily anchoring the power plant 3 to the water power plant 1 in order to accommodate the power plant, so as to facilitate smooth docking of the power plant 3 to the battery buoyancy module 2 at the power plant 1. In alternative embodiments, electromagnetic adsorption anchoring may also be employed.

In the illustrated example, eight buoyancy bits 11 are provided in total at the docking area of the station, of which six are shown on the left side, where the battery buoyancy tanks 2 are stored, two on the right side, and each two buoyancy bits 11 constitute one docking bit 12, i.e. the above-water station 1 provides four docking bits in total. Each docking station can receive one exchange ship 3, and the battery buoyancy tanks 2 in two adjacent buoyancy stations 11 are docked by the exchange ship 3 and towed away from or stored to the water exchange station with the aid of water surface buoyancy.

In an alternative embodiment, the number of buoyancy bits 11 forming one connection bit 12 is not limited, and one or a plurality of buoyancy bits can be set according to actual requirements. Also, the number of the docking stations 12 in the docking area of the power exchange station is not limited, and may be set to one or more according to actual requirements. Alternatively, the bottom of the docking station 12 may have a floor as shown in the figures, or may be free of a floor, leaving the battery buoyancy module 2 floating directly in the water. The buoyancy of the battery buoyancy module can reduce the force pulling the battery buoyancy module when the battery buoyancy module is in the condition of having a bottom plate, the battery buoyancy module can float in water without contacting the bottom plate, and can also contact the bottom plate.

Optionally, a limiting device (not shown) may be disposed on the side of each buoyancy position 11 of the power exchange station, where the limiting device may limit the active position of the battery buoyancy module 2 when the battery buoyancy module 2 floats on the buoyancy position 11 of the power exchange station, further prevent the battery buoyancy modules 2 in each connection position from being damaged due to collision, and separate each connection position 12.

Alternatively, the limiting device may be a stop lever as shown in fig. 2, a baffle plate or a rope, etc., so long as the movable position of the battery buoyancy module 2 can be limited when the battery buoyancy module floats. In an alternative embodiment, a limiting device may be disposed before and after each power exchange station buoyancy station 11 and/or each connection station 12, so as to limit the movable range of the battery buoyancy module 2, and thus, it is easier to quickly store or take out the battery buoyancy module 2.

According to the embodiment of fig. 2, the buoyancy station 11 may optionally be further provided with buoyancy adjustment means 14, which buoyancy adjustment means 14 may adjust the draft of the docking station 12 of the buoyancy station 11 by water intake and drainage, in combination with a number of battery buoyancy tanks which may have an influence on the draft of the buoyancy station 11, compensating when the draft deviates from the normal water line.

The buoyancy adjusting devices 14 can be arranged at two sides of the connection position 12 as shown in fig. 2, namely, the buoyancy adjusting devices 14 balance and adjust the buoyancy of the water power exchange station 1 from two sides so as to adjust the draft of the connection position 12, thereby facilitating the connection of the battery floating cabin 2 by the power exchange ship 3. In an alternative embodiment, the buoyancy adjusting device 14 may be disposed at a middle portion of the connection position 12, where the connection position 12 is distributed on two sides of the buoyancy adjusting device 14, for example, the buoyancy of the water power exchange station 1 may be more conveniently adjusted at a position along the gravity center of the water power exchange station 1, so as to adjust the draft of the connection position 12, thereby facilitating the connection of the power exchange ship 3 to the replacement of the battery floating cabin 2.

Further, the buoyancy adjusting device 14 can adjust the draft of the connection position 12 of the buoyancy position 11 of the power exchange station to be matched with the draft of the buoyancy position 31 of the power exchange ship 3, so that the battery buoyancy chamber 2 can translate between the buoyancy position 11 of the power exchange station and the buoyancy position 31 of the power exchange ship, and the replacement of the battery buoyancy chamber 2 is more convenient.

In alternative embodiments, the buoyancy adjustment device 14 may include, but is not limited to, a pressurized water tank, the buoyancy of which may be adjusted to be greater than the weight of the docking station 12 full of the battery buoyancy tank 2, so that the pressurized water tank may adjust the buoyancy of the above-water power exchange station 1 by not entering or draining water to adjust the draft of the power exchange station buoyancy station 11, thereby facilitating docking of the battery buoyancy tank 2.

In other embodiments, the connection position 12 and the buoyancy position 11 can be located inside the water power exchange station 1 as shown in the drawings, or can be located outside the water power exchange station 1, for example, on the side surface of the water power exchange station in the open air, and the position of the connection position 12 can be adjusted by the buoyancy adjusting device 14 to be matched with the buoyancy position 31 of the power exchange ship, so that the replacement of the battery buoyancy module 2 is facilitated. Whether the docking station 12, the buoyancy station 11 is inside or outside the water power station 1, collision protection may be provided on the sides to protect the battery buoyancy tanks.

According to the embodiment of fig. 2, the water power station 1 is provided with an operation area 17, and in this operation area 17, a worker can monitor the operation condition of the water power station 1, control the water power station 1 to change electricity or monitor the automatic power change of the water power station 1, and the worker can also perform maintenance and other operations on facilities and equipment of the water power station 1. The operation area 17 is arranged in a layer structure close to the buoyancy position 2, so that workers can conveniently and rapidly process the electricity exchanging matters of the electricity exchanging station 1 in a short distance. In an alternative embodiment, the position where the operation area 17 is provided is not limited and may be adjusted according to the convenience of the actual operation.

It can also be seen from the embodiment of fig. 2 that facilities for the life, office, rest, recreation, etc. of the staff can be provided at the life/office area of the water power exchange station 1. The layer may also be fitted with a power transformation facility 15. The power transformation facility 15 adjusts the voltage, current, frequency, etc. of the introduced power supply, and then modulates the power supply into a power supply capable of charging the battery buoyancy module 2 through the charging facility 16, and the power supply is introduced into the buoyancy bit 11 to charge the battery buoyancy module 2 stored therein. The charging facility 16 may be a charging gun 19 connected by a cable, and a charging gun 19 may be provided at each buoyancy station, the charging gun 19 charging the battery buoyancy module 2 stored at the buoyancy station 11. In an alternative embodiment, the installation locations of the power transformation facility 15 and the charging facility 16 are not limited as long as the introduced power source can be modulated into a chargeable power source and introduced into the docking station 12.

In practical application, the water power exchange station 1 can be arranged in a plurality of channels along the water carrier 4 (shown in fig. 5) in the navigation water area, so that the water carrier 4 can conveniently exchange electricity when passing through the water power exchange station 1, and the carrying cost is saved while the water carrier 4 is kept to continuously navigate and the navigation aging is guaranteed.

It should be noted that the model of the above-water power exchange station 1 is not limited, and may be in the form of the embodiment of fig. 2, or may be a semi-submersible pontoon, which is suitable for being berthed offshore or near-shore in inland waters, i.e. the semi-submersible pontoon may be conveniently disposed in a plurality of coasts in the navigation waters of the above-water carrier 4, and may be matched with the matched power exchange vessel 3, so as to facilitate the power exchange of the above-water carrier 4 on its channel.

Fig. 3 is a schematic perspective view of a power conversion ship of an embodiment of the water power conversion system of the present invention.

The power exchange ship 3 is used for connecting the battery buoyancy chamber 2 from the buoyancy position 11 of the water power exchange station 1, so that the battery buoyancy chamber 2 is pulled to the water carrier 4 for replacement, and the power exchange of the water carrier 4 is realized.

According to the illustrated example, the vessel 3 may have a battery buoyancy station 31, which buoyancy station 31 is open to the water surface, and the battery buoyancy tank 2 may float at the buoyancy station 31. During transport of the vessel 3, the battery pod 2 follows the vessel 3 in the vessel buoyancy 31. In alternative embodiments the vessel may not be provided with buoyancy, but may be directly carrying the battery pod.

In some embodiments, the sides of the buoyancy position 31 of the power exchange vessel may be provided with a limiting device, such as a ship board as shown in fig. 3, which can limit the movable position of the battery buoyancy tanks 2 when the battery buoyancy tanks 2 float on the buoyancy position 31 of the power exchange vessel, and further prevent the battery buoyancy tanks 2 in the buoyancy position 31 of the power exchange vessel from being damaged due to collision with each other. In some embodiments, the vessel may also be configured as bottomless and/or bottomless devices.

Alternatively, the limiting device may be a stop lever, a partition plate, a rope, or the like, so long as the limiting device can limit the movable position of the battery buoyancy chamber 2 and prevent collision when the battery buoyancy chamber is shifted left and right. In an alternative embodiment, the limiting device can be arranged on one side of the buoyancy position 31 of the power exchange ship or on two sides of the buoyancy position 31 of the power exchange ship, and the limiting devices can be arranged on the front and back of each buoyancy position 31 of the power exchange ship to limit the movable range of the battery buoyancy module 2, so that in order to easily and quickly store or take out the battery buoyancy module 2, some limiting devices can be operated to cancel the limitation.

In other embodiments, the power exchange vessel 3 may also have a buoyancy adjusting device (not shown in the figure), for example, may be a pressurized water tank in the side of the two sides, and the buoyancy adjusting device may adjust the buoyancy of the power exchange vessel 3 to adjust the draft of the buoyancy position 31 of the power exchange vessel, so as to facilitate connection of the battery buoyancy tank 2.

Further, in the actual power exchange process, the draft of the power exchange ship and the draft of the power exchange station can be adjusted through the buoyancy adjusting device to be matched, so that the battery floating cabin 2 can translate between the power exchange ship buoyancy position 31 and the power exchange station buoyancy position 11, and the replacement of the battery floating cabin 2 is more convenient. Likewise, the buoyancy adjusting device can also adjust the draft of the power exchange ship and the draft of the water carrier (shown in fig. 5) so that the two are matched, and therefore the battery buoyancy module 2 can translate between the power exchange ship buoyancy position 31 and the water carrier buoyancy position 47, and the replacement of the battery buoyancy module 2 is more convenient.

In alternative embodiments, the buoyancy adjustment device may include, but is not limited to, a pressurized water tank that may adjust the buoyancy of the power conversion vessel 3 by water intake or drainage to thereby adjust the draft of the power conversion vessel.

Fig. 4 is a schematic perspective view of a battery compartment of the water power conversion system according to an embodiment of the present invention.

As can be seen from the embodiment of fig. 4, the battery buoyancy module 2 has a module 21, and a power battery (not shown) is placed in the module 21, and is used for providing power for sailing the water carrier 4. When the battery is replaced, the battery buoyancy module can be pulled between different positions on the water surface through the battery replacement ship.

In the illustrated example, the power battery is completely enclosed within the compartment 21 to protect the power battery disposed therein from external impacts and damage. And, when the battery buoyancy module 1 floats on the water surface, the module body 21 can provide waterproof protection and temperature adjustment for the power battery, prevent external water from entering to influence the normal operation of the power battery, and can be used for adjusting and keeping the battery buoyancy module 1 floats on the water surface and keeping the battery buoyancy module 1 within a set working temperature range. The cabin 21 may be independent of the housing of the power cell or integrally formed with the housing of the power cell.

In an alternative embodiment, the cabin 21 may also partially cover the power battery 11, and the exposed part of the power battery 11 may be located above the water line of the battery buoyancy module 1, so as to prevent external water from entering and affecting the normal operation of the power battery 11.

As can be seen from fig. 2 and 3, when the battery buoyancy chamber 2 is located at the buoyancy position 11 of the above-water power exchange station and the buoyancy position 31 of the power exchange ship, the buoyancy of the above-water power exchange station 11 and the buoyancy of the power exchange ship 31 can provide buoyancy for the battery buoyancy chamber 2, so that the battery buoyancy chamber 2 can be conveniently moved by means of buoyancy through manual operation only by traction.

In various embodiments, the battery buoyancy module 2 may also be provided with buoyancy adjustment means that may adjust the draft of the battery buoyancy module 2 to facilitate docking of the battery buoyancy module 2.

Further, the buoyancy adjusting device can be used for adjusting the draft of the battery buoyancy chamber 2 and the water power exchange station (shown in fig. 2), and the same can be used for adjusting the draft of the battery buoyancy chamber 2 and the power exchange ship (shown in fig. 3), so that the battery buoyancy chamber 2 can be conveniently and quickly replaced at the buoyancy position 11 of the water power exchange station and the buoyancy position 31 of the power exchange ship.

In alternative embodiments, the buoyancy adjusting device may include, but is not limited to, a pressurized water tank having an adjusting buoyancy greater than the weight of the battery buoyancy tank 2, so that the pressurized water tank may adjust the buoyancy and draft of the battery buoyancy tank 2 by water intake or drainage, thereby facilitating replacement of the battery buoyancy tank 2.

It can also be seen from the embodiment of fig. 4 that the battery pod 2 also has a power interface 22, which power interface 22 can be connected to the charging facility 16 of the charging station 1 on water for charging. The power interface 22 may also be connected to the water carrier 4 to provide power to the water carrier 4.

Fig. 5 is a schematic perspective view of an embodiment of a water carrier of a water power conversion system according to the present invention.

The water power exchanging system of the invention can also comprise a water carrier 4. The water craft 4 may be an electric or hybrid craft which may have an internal or external battery pod buoyancy station so that the battery pod may be attached to the water craft at the buoyancy station. In the built-in case, the buoyancy position can be positioned between the propellers at two sides of the tail of the water carrier.

As shown in fig. 5, in this example, the water carrier 4 is composed of a split type 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 draft, and the draft change of the carrying cabin 41 does not affect the draft of the power cabin 42. The cargo tanks 41 may be, but are not limited to, pleasure boats, passenger ships, freight ships, barges, yachts, etc., and may be used for carrying personnel, cargo, etc. on water.

The power pod 42 may be provided with a buoyancy location 47 that is open to the water surface, the battery pod 2 may be attached to the buoyancy location 47, and the battery pod 2 may float at the buoyancy location 47, with the aid of the water surface at the buoyancy location 47 to facilitate traction and replacement of the battery pod 2. In particular, the buoyancy station 47 may be internal or external to the electric vessel, such that a battery pod may be built in or external, respectively.

Alternatively, the power pod 42 of the water craft 4 may also have buoyancy adjustment means which can change the draft of the power pod 42 by adjusting the buoyancy of the power pod 42 of the water craft 4, thereby facilitating replacement of the battery pod 2.

Further, the draft of the water carrier can be adjusted to match the power conversion ship, so that power can be conveniently and quickly converted between the buoyancy position 31 of the power conversion ship and the buoyancy position 47 of the water carrier.

In alternative embodiments, the buoyancy adjustment device may include, but is not limited to, a pressurized water tank that may adjust the draft of the watercraft buoyancy position 47 by either water intake or water discharge.

It can also be seen from the embodiment of fig. 5 that the power pod 42 may be equipped with two battery buoyancy pods 2. Specifically, in the illustrated example, the water craft's cargo tanks and power tanks are provided separately, with a buoyancy station provided between the two propellers at the tail of the power tanks, to which the battery buoyancy tanks are attached. The power cabin can push the carrying cabin at the tail part of the carrying cabin, and can also drag the carrying cabin at the front part of the carrying cabin. The driving operation room of the water carrier can be positioned in the carrying cabin or the power cabin, and when the driving operation room is positioned in the carrying cabin, the power device of the power cabin can be controlled through a data connection line to control the pushing of the power cabin to the carrying cabin.

In the practical application process, the number of the battery floating cabins 2 installed in the power cabin 42 is not limited, and can be adjusted according to practical situations. When the carrying cabin 41 has power for sailing, the power cabin 42 can be provided with only one battery floating cabin 2 as auxiliary power, and when the carrying cabin 41 has large tonnage, the power cabin 42 can be provided with a plurality of battery floating cabins 2 to provide enough sailing power.

When the water carrier 4 is only provided with the navigation power supply by the battery buoyancy module 2 of the power module 42, in order to ensure continuous navigation of the water carrier 4, at least one battery buoyancy module can be ensured to continuously provide power for navigation power of the water carrier when the battery buoyancy module is replaced.

The invention also provides a power conversion method for converting the power of the water vehicle by using the water power conversion system in any one of the previous embodiments, which comprises the following steps that the power conversion ship is connected with a battery buoyancy cabin between the power conversion station and/or the water vehicle by means of buoyancy. Therefore, the power conversion method also has the advantage of convenient traction corresponding to the above-mentioned water power conversion system. In an alternative embodiment, the method may further comprise the step of arranging a plurality of water power stations 1 on the operating channel of the water carrier 4 for providing power switching services for the water carrier.

When the water carrier 4 needs to change electricity, the electricity changing ship 3 conveniently and quickly connects the battery buoyancy chamber 2 with full electric quantity from the buoyancy position 11 of the water electricity changing station 1 by means of the buoyancy of water. Optionally, the buoyancy adjusting device of the water power exchange station 1 and/or the power exchange ship 3 can be used for adjusting so that the draft of the power exchange station is matched with that of the power exchange ship, and the battery floating cabin 2 can be replaced conveniently and quickly.

The battery buoyancy module 2 with full electric quantity is transported to the water carrier 4 in the navigation water area by the electricity exchange ship 3, and the battery buoyancy module 2 with low electric quantity is conveniently and rapidly replaced with the water carrier 4 by means of buoyancy. Alternatively, the buoyancy adjustment device of the electricity changing ship 3 can be used for adjusting the draft depth of the buoyancy position 31 of the electricity changing ship to match the buoyancy position 47 of the water carrier, so that the battery buoyancy module 2 can be replaced conveniently and quickly.

When the power is changed in a moving way, the speed of the power changing ship 3 can be kept the same as the navigation speed and direction of the water-borne carrier 4, namely, the water-borne carrier 4 does not need to be decelerated during power changing and can continuously navigate, so that the navigation power of the water-borne carrier is kept, the power changing of the battery floating cabin of the water-borne carrier is conveniently completed, and the navigation cost is saved while the navigation timeliness of the power changing ship is ensured. The power can be changed after the water carrier is parked.

The replacement ship 3 conveys the replaced low-power battery buoyancy module 2 to the water replacement station 1, and the low-power battery buoyancy module 2 is connected to the replacement station buoyancy station 11 of the water replacement station 1 by means of buoyancy. Optionally, the buoyancy adjusting device of the water power exchange station 1 and/or the power exchange ship 3 can be used for adjusting, so that the draft of the power exchange station is matched with the draft of the power exchange ship, and the battery buoyancy module 2 can be conveniently and quickly connected.

Alternatively, the low-power battery buoyancy module 2 may be connected to a charging gun 19 at the buoyancy station 11 of the power exchange station for charging, and after full charging, the low-power battery buoyancy module may be used for subsequent power exchange of the water carrier 4.

The technical scope of the present invention is not limited to the above description, and those skilled in the art may make various changes and modifications to the above-described embodiments without departing from the technical spirit of the present invention, and these changes and modifications should be included in the scope of the present invention.
