Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

As described in the background art, in the prior art, the shipping is mainly driven by an internal combustion engine, and a large amount of petrochemical energy is required to be consumed, so that the development of inland shipping electrification is significant in realizing the electric traction of the ship.

However, if the internal combustion engine is directly replaced with an energy storage type electric system using a battery, an excess capacity and the like as a carrier, the weight of the ship is increased, the precious space of the ship is occupied, the transportation efficiency of the ship is reduced, and the energy storage of the energy storage type electric system is difficult to realize high-power and long-distance transportation because the weight and the volume of the energy storage type electric system are limited.

In view of the above, in order to solve the above problems, the embodiments of the present application provide a power supply vehicle, which does not need to provide an energy storage device such as a battery and an ultra-capacity on a ship by moving power supply, so as to reduce the weight of the ship, save space, and achieve the advantage of improving transportation efficiency.

The following illustrates an exemplary power supply vehicle provided by the present application:

As an alternative implementation manner, referring to fig. 1, the power supply vehicle 100 is applied to a vehicle-ship cooperative electrified water transportation system, and the vehicle-ship cooperative electrified water transportation system further comprises a power supply rail and a ship 200, wherein the power supply vehicle 100 comprises a current receiving module 110 and a power module 120, the current receiving module 110 is respectively and electrically connected with the power supply rail and the power module 120, the ship comprises a driving module, the current receiving module 110 is further electrically connected with the driving module of the ship 200 through a cable 130, the power supply vehicle 100 moves along the extending direction of the power supply rail, the power supply vehicle 100 moves synchronously with the ship 200, and the current receiving module 110 is used for taking current from the power supply rail and supplying power to the power module 120 and the ship 200.

Referring to fig. 2, the ship 200 sails in the river, the power supply rail may be disposed at a side of the river, and the power supply vehicle 100 moves along an extending direction of the power supply rail and takes power from the power supply rail to supply power to the power supply vehicle 100 and the ship 200. As shown, power cart 100 is connected to vessel 200 via cable 130 and provides power to vessel 200. Alternatively, power supply rails may be disposed on two sides of the river channel, and in the sailing process of the ship 200, power may be taken from different power supply rails through the power supply vehicle 100 according to different sailing directions.

For example, referring to fig. 3, a ship 200 sails between two points A, B, power supply rails are disposed on two sides of the river channel, and the two sides of the river channel are an upstream side and a downstream side, respectively, when the ship 200 sails from the point a to the point B, the ship sails near the downstream side and draws power from the power supply rail on the downstream side through the power supply car 100, and when the ship 200 sails from the point B to the point a, the ship sails near the upstream side and draws power from the power supply rail on the upstream side through the power supply car 100.

In one implementation, as shown in fig. 3, the power supply rail may be configured as a ring, and for a ship with a relatively fixed heading, such as a passenger ship or a cargo ship with a fixed line, if the power supply vehicle 100 starts from the point a to the point B, power is taken from the power supply rail on the side of the downstream river, and when the power supply vehicle starts from the point B to the point a, power is taken from the power supply rail on the side of the upstream river by the power supply vehicle 100. Through the implementation manner, when a plurality of ships 200 are simultaneously sailed, the power supply vehicle 100 and the ships 200 can move in sequence, so that the occurrence of ship collision accidents can be avoided, and the ship sailing device is safe, reliable and high in practicability.

Optionally, when the point a and the point B are both docks, an annular track bridge may be formed between A, B, if the power supply vehicle 100 starts from the dock a to the dock B, in one implementation manner, after reaching the dock B, the power supply vehicle 100 may be turned around from the downstream river side to the upstream river side in a turning-around manner, and the power supply vehicle 100 also moves from the downstream river side to the upstream river side.

In another implementation mode, the vehicle-ship cooperative electrified water transportation system further comprises a power tug, the ship is separated from the power supply vehicle when reaching the first destination, and the power tug is used for pulling the ship to the second destination, wherein the first destination and the second destination are respectively positioned on two sides of the river channel.

That is, after the power supply vehicle 100 gets power from the power supply rail at the side of the downstream river, and reaches the dock B, the cable 130 of the power supply vehicle 100 is separated from the ship 200, the ship 200 is towed to the side of the upstream river of the dock B by the power tug, the power supply vehicle 100 runs to the upstream side, and the power supply vehicle waits for supplying power to the ship driven to the dock a by the dock B, so that a cycle is formed.

One end of the current receiving module 110 provides power for the motion of the power supply vehicle 100 and also provides power for the ship 200 after power is taken from the power supply rail.

In one implementation, referring to fig. 4, in order to facilitate the running of the electric power supply vehicle 100, the vehicle-ship cooperative electrified water transportation system further includes a track bridge and a running rail, the track bridge is installed on the river bank of the channel, the running rail and the power supply rail are both installed on the track bridge, and the electric power supply vehicle 100 is installed on the running rail and moves along the running rail. Wherein, the track bridge can be built in the river course both sides to, the track bridge extends along the river course direction, and in an implementation, the track bridge can be with river course parallel arrangement. And, both the running rail and the power supply rail are built on the track bridge, and the power supply vehicle 100 moves along the running rail.

Through this setting up mode for walking the track and presenting certain difference in height with the surface of water with the power supply rail, walk the track and be difficult for breaking down with the power supply rail, and when power supply vehicle 100 moves along walking the track, be difficult for being blocked by other objects, provide the guarantee for the normal operating of power supply vehicle 100.

On this basis, it can be understood that when the ship 200 is sailed in a river channel, the electric vehicle 100 moves on the running rail and the electric vehicle and the running rail move synchronously, wherein the synchronous movement in the application means that the movement directions of the electric vehicle and the running rail are the same and the movement speeds of the electric vehicle and the running rail are the same. When the power supply vehicle 100 moves on the running rail, the power supply vehicle 100 will take power from the power supply rail at the same time, so as to provide power for the power module 120 of the power supply vehicle 100 itself, and simultaneously, power the ship 200 through the cable with the grid power, so as to provide power for the ship 200, or provide power for the load on the ship 200.

It should be noted that, since the ship 200 is easy to sway and shake during the course of sailing, and further the problems of power interruption caused by detachment due to sliding such as a pantograph may be caused, the cable 130 provided by the present application may use the cable 130 having a certain flexibility and a certain expansion and contraction ductility, and further, when the ship 200 is swaying, the ductility of the cable 130 may be still utilized to avoid the failure during the power supply process, so as to provide reliable power supply for the ship 200.

As an implementation manner, please refer to fig. 1 again, the power module 120 includes a traction current transformer 121, a traction motor 122 and a controller 123, wherein the traction current transformer 121 is electrically connected with the traction motor 122 and the current receiving module 110, respectively, an input end of the traction current transformer 121 is electrically connected with the current receiving module 110, an output end of the traction current transformer is electrically connected with the traction motor 122, and the controller 123 is communicatively connected with a control end of the traction current transformer 121, and the controller 123 is used for controlling the rotation speed of the traction motor 122 to drive the electric car and controlling the movement speed thereof by controlling the traction current transformer 121 to perform frequency modulation and voltage regulation.

The vehicle traction converter 121 can output a designated frequency and voltage under the control of the vehicle controller 123, and control the motion of the vehicle traction motor 122, so as to drive the power supply vehicle 100 to move. Specifically, the bottom of the power supply vehicle 100 is provided with wheels, and the wheels can move along the running rail under the drive of the vehicle traction motor 122.

Meanwhile, in order to ensure synchronous operation between the ship 200 and the electric vehicle 100, the vehicle controller 123 is further configured to be in communication with the ship 200 and obtain the speed of the ship 200, and the vehicle controller 123 may control the output frequency and voltage of the vehicle traction converter 121 according to the speed of the ship 200, and change the rotation speed of the vehicle traction motor 122 through voltage transformation and frequency conversion, so as to control the operation speed of the electric vehicle 100, and make the electric vehicle 100 and the ship 200 operate synchronously.

Alternatively, the vehicle controller 123 may be communicatively connected to the ship 200 by a wired or wireless method, where when a wireless communication method is used, a near field communication method, such as a bluetooth, WIFI, cellular, or other communication method, may be used because the distance between the power supply vehicle 100 and the ship 200 is relatively small. When communicating in a wired manner, optical fiber communication may be employed and the optical fiber may be laid along with cable 130 to form a composite cable. By means of the composite cable, on one hand, only one line is connected with the ship 200, the line is simpler, the fault probability is smaller, and on the other hand, the cable strength can be improved, so that the cable can bear larger acting force.

In one implementation, the vehicle-ship cooperative electrified water transportation system further comprises a driving mechanism, the driving mechanism is arranged on the electric power supply vehicle and is in communication connection with the power module, and the power module is in communication connection with the driving module, wherein the driving mechanism is used for sending a navigation instruction to the power module and the driving module and controlling the running states of the power module and the driving module according to the navigation instruction.

Through the arrangement mode, a driver can be located on the ship, and the running direction and the running speed of the electric power supply vehicle and the running speed of the ship are controlled simultaneously through the driving mechanism.

Of course, in other implementations, the driving mechanisms are not arranged on the power supply vehicle and the ship, and the communication modules are arranged on the power supply vehicle and the ship, so that the communication between the communication modules and the background terminal is performed, and the effects of remotely controlling the running direction and the running speed of the power supply vehicle and the ship are further achieved. The background terminal may be an electronic terminal such as a mobile phone, a computer, or a wearable device of the driver, or may be an electronic terminal such as a background server, which is not limited herein. When the power supply vehicle and the ship are controlled by the background terminal, the application of the power supply vehicle and the ship can be more flexible, for example, a driver can stand on the ground to control the ship and the power supply vehicle, or the driver can stand on the ship to control the ship and the power supply vehicle through a mobile phone, and the power supply vehicle is not limited.

In general, the installation position of the steering mechanism is associated with the installation positions of the vehicle controller and the ship controller. For example, referring to fig. 5, the traction converter for vehicle is disposed on the power supply vehicle, the traction converter for ship is disposed on the ship, at this time, the controller for vehicle is further disposed on the power supply vehicle, the controller for ship is further disposed on the ship, the controller for ship is connected with the traction motor for ship, and the controller for vehicle is in communication connection with the controller for ship. In this example, the steering mechanism is disposed on the vessel, and the steering mechanism is connected to the vessel controller. At this time, the user can drive on the boats and ships, and marine controller is when receiving navigation instruction back, and when driving marine traction current ware and marine traction motor operation, can send corresponding signal to automobile-used controller for automobile-used controller control automobile-used traction current ware and automobile-used traction motor synchronous operation, and then guaranteed the synchronous operation all the time between supply vehicle and the boats and ships.

Of course, as shown in fig. 6, the steering mechanism may be provided on the electric power supply vehicle, so that the user can control the speed and heading of the ship on the electric power supply vehicle, and realize synchronous operation of the electric power supply vehicle and the ship.

In one implementation, the marine traction converter is larger and heavier, so that the marine traction converter can be arranged on a power supply car for reducing the dead weight of the ship and the occupied space of the ship, and referring to fig. 7, when the marine traction converter is arranged on the power supply car, the cable comprises a power cable and a transmission cable, the vehicle traction converter is connected with the marine traction motor through a transmission cable, the power supply vehicle and the ship can share the same vehicle controller, the driving mechanism is arranged on the power supply vehicle, and after the vehicle controller receives a driving instruction sent by the driving mechanism, the vehicle controller can respectively control the running states of the vehicle traction converter and the marine traction converter, so that synchronous running of the power supply vehicle and the ship is realized.

Optionally, the driving module comprises a ship traction converter and a ship traction motor, the ship traction converter is arranged on the power supply vehicle or the ship, and when the ship traction converter is arranged on the power supply vehicle, the cable comprises a power cable and a transmission cable, the current receiving module supplies power for a ship power distribution unit of the ship through the power cable, and the ship traction converter is electrically connected with the ship traction motor through the transmission cable. The power cable is used for supplying power to a power distribution unit on the ship, and the power distribution unit supplies power to an air conditioner and an illumination non-traction load of the ship.

Or referring to fig. 8, the power supply vehicle and the ship can share the same ship controller, and the driving mechanism is arranged on the ship, and when the ship controller receives the driving instruction sent by the driving mechanism, the running states of the vehicle traction converter and the ship traction converter are respectively controlled, so that synchronous running of the power supply vehicle and the ship is realized.

Furthermore, the application provides that the cable can be detachably connected, for example pluggable, to the power supply and/or the vessel.

In addition, as an implementation mode, the vehicle-ship cooperative electrified water transportation system further comprises a traction rope, one end of the traction rope is mechanically connected with the power supply vehicle, and the other end of the traction rope is mechanically connected with the ship. The haulage rope is detachably connected with the power supply vehicle and/or the haulage rope is detachably connected with the ship, namely the haulage rope is fixedly connected with the ship, and the haulage rope is detachably connected with the power supply vehicle, or the haulage rope is detachably connected with the ship, and the haulage rope is fixedly connected with the power supply vehicle, or the haulage rope is detachably connected with the ship, and the haulage rope is detachably connected with the power supply vehicle.

By arranging the traction rope, the cable is damaged because the cable is pulled once the power supply vehicle and the ship are synchronous and the power supply vehicle and the ship are not synchronous. After the traction rope is arranged, when the traction rope is pulled, the traction rope bears the tension, so that the effect of protecting the cable is achieved. In the second aspect, when any one of the power supply vehicle or the ship breaks down to cause no power, the two can be ensured to run synchronously through the pulling force of the pulling rope. For example, when the power module of the power supply car fails, the ship can pull the power supply car to run synchronously through the traction rope during running.

In combination with the above, the working principle of the power supply vehicle 100 provided by the present application is as follows:

The flexibility and the retractility of the cable are used to connect the ship and the power supply car to accommodate the sway of the ship in the water and to maintain reliable power supply to the ship. The power supply car 100 runs on the running rail of the overhead track bridge, the power of the ground power grid is sent to the ship through the cable 130, meanwhile, the power supply car 100 is provided with the vehicle traction converter 121 and the vehicle traction motor 122, speed control is carried out through frequency conversion and voltage transformation, and synchronous running is achieved through communication with the ship 200. On this basis, the ship 200 can acquire the power supply through the cable 130, so that a battery and an ultra-capacity energy storage device are not required to be arranged on the ship 200, the space is saved, the self weight of the ship is lightened, and the transportation efficiency of the ship 200 is improved.

Based on the implementation manner, the embodiment of the application also provides a driving module, referring to fig. 5, the driving module is applied to a ship, the driving module comprises a ship traction current transformer, a ship controller and a ship traction motor, the ship traction current transformer is respectively and electrically connected with the ship traction motor and the current receiving module, the ship traction current transformer is also in communication connection with the ship controller, and the ship controller is used for controlling the ship traction current transformer to supply power to the ship traction motor so as to drive the ship to move.

On the basis, the embodiment of the application also provides a power supply system which comprises the power supply vehicle and the driving module, wherein the power supply vehicle is electrically connected with the driving module and supplies power for the driving module.

In practical application, the driving module may be installed on an existing ship, and the driving module is electrically connected to the power supply vehicle through the cable 130, so as to implement electrification of the existing ship.

The application also provides a ship which is applied to the vehicle-ship cooperative electrified water transportation system, the vehicle-ship cooperative electrified water transportation system further comprises a power supply vehicle, and the ship comprises the driving module.

The ship traction motor 220 is connected with the propeller, and the ship traction converter 210 obtains power from the power supply vehicle 100, and the ship controller 230 controls the output frequency and voltage of the ship traction converter 210, and changes the rotation speed of the ship traction motor 220 in a variable-voltage and variable-frequency mode, so as to drive the propeller to drive the ship 200 to travel.

Because the power source of the ship 200 comes from the ground power grid, energy storage equipment such as a battery is not required to be arranged on the ship 200, the weight of the ship 200 is reduced, the space of the ship 200 is saved, and the transportation efficiency is improved.

In order to ensure synchronous movement between the ship 200 and the power supply vehicle 100, the ship 200 further comprises a course speed sensor 240, the course speed sensor 240 is in communication connection with the ship controller 230, the ship controller 230 is also in communication connection with the power supply vehicle 100, the course speed sensor 240 is used for acquiring course and speed information of the ship 200, and the ship controller 230 is used for sending the course and speed information to the power supply vehicle 100.

By providing the heading speed sensor 240, the speed and heading of the ship 200 can be obtained in real time, and the speed and heading are fed back to the electric vehicle 100, so as to realize a synchronous operation mode of 'following the ship'. Naturally, the speed of the power supply vehicle can be obtained in real time, so that the navigation speed and direction of the ship can be adjusted, and the synchronous running mode of 'following the ship' can be realized.

In addition, the marine controller 230 may determine the rotational speed of the marine traction motor 220 according to the heading and speed information, and determine the output frequency and voltage of the marine traction converter 210 according to the rotational speed of the marine traction motor 220.

For example, when yaw occurs in the course of the ship 200 due to wind force or water current or the like, there may occur a case where the distance between the ship 200 and the power supply car 100 gradually increases, resulting in damage after the cable 130 reaches the maximum length. Or the ship 200 sails at a certain speed, and when it encounters an environmental influence such as water flow, the sailing speed may be slow, and the speed of the ship 200 needs to be adjusted.

Under the above scenario, after obtaining the heading and the navigational speed information, the marine controller 230 calculates the output frequency and the voltage of the corresponding marine traction converter 210, so that the marine measurement and control device controls the output of the marine traction converter 210, changes the rotation speed of the marine traction motor 220 through voltage transformation and frequency conversion, and drives the propeller to drive the ship 200 to travel at a speed. Meanwhile, the power supply vehicle 100 can also be adjusted synchronously, and the ship controller 230 and the vehicle controller 123 are coordinated to control the ship 200 and the power supply vehicle 100 to run synchronously within the allowable range of the length of the cable 130.

In addition, there may be an electrical load on the ship 200, such as an air conditioner, a television, and the like, and therefore, the ship 200 further includes a ship power distribution unit 250, and the ship power distribution unit 250 is electrically connected to the current receiving module 110, wherein the ship power distribution unit 250 is configured to obtain power from the current receiving module 110 and distribute power to the load on the ship 200. For example, the marine power distribution unit 250 performs power distribution according to the required power of different loads, so as to achieve the purpose of power distribution.
