DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0043] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] Existing ships are generally driven by internal combustion engines, which consume a lot of petrochemical energy, causing energy consumption and pollution problems. Therefore, in order to improve this problem, shipping electrification can be developed to use electricity as a power source.

[0045] However, if the internal combustion engine is directly replaced with an energy storage electric system using batteries, supercapacitors, etc. as carriers, the cost will increase and the weight of the ship will increase. At the same time, it will occupy precious space on the ship and reduce the ship's transportation efficiency. In addition, due to the weight and volume limitations of the energy storage electric system, its energy storage is difficult to achieve high-power and long-distance transportation. Otherwise, the cost will be extremely high.

[0046] In view of this, in order to solve the above problems, an embodiment of the present application provides a power supply vehicle, which does not arrange a power system on the ship, but uses the power supply vehicle to drive the operation of the ship, thereby minimizing the ship's own weight to the greatest extent, while not occupying the effective space of the ship, increasing the ship's carrying capacity and improving transportation efficiency.

[0047] It should be noted that in the current technology, there are solutions for tractors to tow ships. For example, the CN110901831A solution provides a solution for towing ships in tunnels. However, the application scenarios of this solution are limited and can only be used for towing in tunnels; at the same time, multiple tractors are required to tow ships at the same time. This application provides a new water transport electrification solution, in which the power supply vehicle can tow the ship while supplying power to the ship, and is applicable to all working conditions of the ship.

[0048] The following is an exemplary description of the power supply vehicle provided in this application:

[0049] As an implementation, see Figure 1 and Figure 2 The electrified water transport system includes a power supply vehicle 100, a cable 500, a traction rope 400, a power supply rail 300, a ship 200 and a controller 130. The power supply vehicle includes a current receiving module 110 and a traction power module 120. The current receiving module 110 is electrically connected to the traction power module 120 and the power supply rail 300 respectively. The current receiving module 110 is also electrically connected to the ship 200 through the cable 500. The power supply vehicle 100 and the ship 200 are also mechanically connected through the traction rope 400; wherein the current receiving module 110 is used to take current from the power supply rail 300, and supply power to the traction power module 120 and the ship 200 through the cable 500; the traction power module 120 is used to drive the power supply vehicle to run along the extension direction of the power supply rail 300; the power supply vehicle is used to drive the ship 200 to run synchronously through the traction rope 400 during operation, and the traction power device on the ship 200 is not started.

[0050] The traction power device is not started on the ship described in this application, which means that the ship is not equipped with a traction power device, or that the ship is equipped with a traction power device but is not used, and the ship is only towed by the power of the power supply vehicle. For example, when the traction power device on the ship fails, the power of the power supply vehicle can be used to tow the ship.

[0051] It can be understood that the power supply vehicle set up in this way can, on the one hand, run along the power supply rail 300 under the drive of the traction power module 120, and drive the ship 200 to run while supplying power to the ship 200, thereby eliminating the need to arrange a traction power system on the ship 200, thereby saving costs. On the other hand, since there is no need to arrange a traction power system on the ship 200, there is no need to arrange energy storage batteries or marine traction inverters and motors on the ship 200, thereby reducing the weight of the ship 200 and leaving more carrying space for the ship 200, thereby achieving the purpose of increasing the carrying capacity of the ship 200. For example, when the ship 200 is a cargo ship, it can carry more cargo; when the ship 200 is a passenger ship, it can carry more passengers, thereby improving the overall transportation efficiency.

[0052] As an implementation method, please continue to see Figure 1 The traction power module 120 includes an on-board traction inverter 121 and an on-board traction motor 123. The on-board traction inverter 121 is electrically connected to the current receiving module 110. The on-board traction inverter 121 is also electrically connected to the on-board traction motor 123 respectively, and the input end of the on-board traction inverter 121 is communicatively connected to the output end of the controller 130; wherein the controller 130 is used to control the on-board traction inverter 121 to perform frequency and voltage modulation to control the speed of the on-board traction motor 123, so as to adjust the running speed of the power supply vehicle and synchronously drive the ship to run.

[0053] Among them, the current receiving module 110 draws power from the power supply rail 300, and the controller 130 is used to convert the set speed into the corresponding frequency and voltage data and output it to the on-board traction inverter 121. The on-board traction inverter 121 is used to control the on-board traction motor 123 according to the frequency and voltage to drive the power supply vehicle to run. It should be noted that since the power supply vehicle always runs along the extension direction of the power supply rail 300, in actual settings, only the speed of the power supply vehicle can be controlled without controlling the running direction of the power supply vehicle.

[0054] See also Figure 3In one implementation, the power supply vehicle further includes a driving mechanism 140, which is connected to the controller 130 in communication, and the driving mechanism 140 is used to send navigation instructions to the controller 130, and the controller 130 is used to control the speed of the on-board traction motor 123 through the on-board traction inverter 121 according to the navigation instructions to adjust the running speed of the power supply vehicle; at the same time, the ship includes a steering gear 220, which is connected to the controller 130 in communication, and the controller 130 is also used to control the working state of the steering gear 220 according to the navigation instructions to adjust the heading of the ship. Of course, the ship can also include a heading speed sensor 230, which is connected to the controller 130 in communication, and the heading speed sensor is used to measure the heading and speed of the ship, and send the heading and speed data to the controller 130.

[0055] In this implementation, the driver can be located in the power supply vehicle to drive. Specifically, the driver can control the speed of the power supply vehicle through the driving mechanism in the vehicle. At the same time, the power supply vehicle can be connected to the ship through communication. A steering gear can be set on the ship. The driver can also control the working state of the steering gear through the instructions of the driving mechanism, and then control the heading of the ship. Since the power supply vehicle tows the ship, the speed of the ship is the same as the speed of the power supply vehicle, so that the driver can control the speed and heading of the ship on the power supply vehicle. Of course, the driver can also use the driving mechanism to control the running speed of the power supply vehicle, which will not be elaborated here.

[0056] In another implementation, see Figure 4 The driving mechanism and controller of the electric water transport system of the vehicle tugboat can also be set on the ship, the driving mechanism is connected to the controller; the controller is connected to the vehicle-mounted traction inverter through optical fiber; the driving mechanism is used to send navigation instructions to the controller, and the controller is used to control the operating state of the vehicle-mounted traction inverter through optical fiber according to the navigation instructions, thereby controlling the speed of the vehicle-mounted traction motor and the operating speed of the power supply vehicle. When optical fiber is used to achieve communication, the optical fiber and the cable can form a composite cable.

[0057] In this implementation, the driver can be on the ship to drive. Specifically, the driver can control the speed of the power supply vehicle through the driving mechanism on the ship, and then use the towing rope to tow the ship to run synchronously. At the same time, a steering gear is set on the ship, and the driver sends the command of the driving mechanism to the controller, and the controller can control the working state of the steering gear, thereby controlling the heading of the ship. At the same time, the driver can also send the command of the driving mechanism to the controller, and the controller controls the on-board traction inverter, and then controls the on-board traction motor, and finally achieves the purpose of controlling the running speed of the power supply vehicle. Since the power supply vehicle tows the ship to run, the speed of the ship along the power supply rail is the same as the speed of the power supply vehicle, so that the driver can control the speed and heading of the ship on the ship.

[0058] For specific applications, please continue to refer to Figure 2 , the ship 200 sails in the river, the power rail 300 can be set on the side of the river, the power supply vehicle moves along the extension direction of the power rail 300, and draws power from the power rail 300, and supplies power to the ship 200 through the cable 500. Optionally, the power rail 300 can be set on both sides of the river, and during the navigation of the ship 200, the power supply vehicle can draw power from different power rails 300 according to different navigation directions.

[0059] Moreover, in one implementation, in order to facilitate the operation of the power supply vehicle, the vehicle-tugboat electrified water transport system also includes a rail bridge 600 and a running rail 700. The rail bridge 600 is laid on the river bank of the waterway, and the running rail 700 and the power supply rail 300 are both installed on the rail bridge 600. The power supply vehicle is installed on the running rail 700 and runs along the running rail 700. Among them, the rail bridge 600 can be built on both sides of the river, and the rail bridge 600 extends along the direction of the river. In one implementation, the rail bridge 600 can be set parallel to the river. Moreover, the running rail 700 and the power supply rail 300 are both built on the rail bridge 600, and the power supply vehicle runs along the running rail 700. That is, in this application, two parallel tracks can be set on the rail bridge 600, namely the power supply rail 300 and the running rail 700, and the power supply vehicle can run along the running rail 700 while taking electricity from the power supply rail 300.

[0060] It can be understood that this arrangement can make the running rail 700 and the power supply rail 300 present a certain height difference with the water surface, and the running rail 700 and the power supply rail 300 are not prone to failure, and when the power supply vehicle moves along the running rail 700, it is not easy to be blocked by other objects, which provides a guarantee for the normal operation of the power supply vehicle. Since the power supply vehicle needs to be connected to the ship 200 through the cable 500 and the traction rope 400, in order to ensure that the cable 500 and the traction rope 400 will not be blocked by other objects, the height of the track bridge 600 can be set to a higher position.

[0061] In a possible implementation, the height of the connection point between the power supply vehicle and the traction rope 400 may be substantially equal to the height of the connection point between the ship 200 and the traction rope 400, or the height of the connection point between the power supply vehicle and the traction rope 400 may be greater than the height of the connection point between the ship 200 and the traction rope 400. Figure 5 As shown, the connection point between the ship 200 and the towing rope 400 is point A, and the connection point between the power supply vehicle and the towing rope 400 is point B. The height of point B is greater than the height of point A. Based on this setting, when the power supply vehicle moves forward, a forward force will be applied to the ship 200 through the towing rope 400. Under the action of this force, a component force extending along the running direction of the power supply vehicle will be generated, and under the action of this component force, the ship 200 will be driven to move forward.

[0062] Furthermore, since the power supply vehicle needs to tow the ship 200 all the time, the power supply vehicle always runs in front of the ship 200. Considering the stability of the force, as an implementation method, one end of the towing rope 400 is connected to the head of the ship 200, and the other end of the towing rope 400 is connected to the tail of the power supply vehicle.

[0063] See also Figure 6 , Figure 6 It is a schematic diagram of the power supply vehicle and the ship 200 from a top-down perspective. When the power supply vehicle runs in the direction of the upward arrow, the ship 200 will be driven by the towing rope 400 and subjected to a force along the direction of the towing rope 400. A force analysis of the force shows that the force can be decomposed into a longitudinal force along the running direction of the power supply vehicle. The longitudinal force can drive the ship 200 to move forward. At the same time, the lateral force of the vertical running rail 700 can also be decomposed. The lateral force can drive the ship 200 to run in the direction close to the power supply rail 300. At this time, it is necessary to control the servo steering gear to generate a reverse force to offset the lateral force to ensure that the ship moves along the running direction of the power supply vehicle.

[0064] Figure 6 In FIG. 1 , the dotted line portion indicates the operable range of the vessel 200 . Theoretically, the vessel 200 can operate within this range.

[0065] It should be noted that the present application does not limit the material of the traction rope 400. Optionally, the traction rope 400 needs to be soft and strong enough, for example, nylon rope can be selected. In addition, during operation, the traction rope 400 is always in a tight state; and as for the cable 500, since the cable 500 does not need to be subjected to force, the cable 500 can be set as a cable with a certain degree of flexibility.

[0066] In one implementation, the cable 500 and the traction rope 400 can be provided independently. In another implementation, the cable 500 and the traction rope 400 can also be integrated into one. After integration, the cable can realize power supply and traction functions at the same time, and only one cable is needed, which is more convenient to manage.

[0067] In actual application, during the operation of the ship 200, it may be necessary to adjust the position. For example, the ship 200 is also provided with a steering gear for adjusting the direction. When a reef or other obstacle appears in front of the ship 200, the ship 200 needs to run around it. At this time, the force between the ship 200 and the power supply vehicle may increase or decrease, which may cause the traction rope 400 to be broken due to excessive force, or the power supply vehicle to derail. In view of this, in order to prevent the above situation from occurring during the operation of the ship 200, the power supply vehicle, the cable 500, and the traction rope 400 are optionally connected in a retractable manner, so that the power supply vehicle can retract the cable 500 and the traction rope 400 to a set length.

[0068] For example, an automatic retractable rack is provided on the power supply vehicle. When the distance between the ship 200 and the power supply vehicle increases, the automatic retractable rack releases longer cables 500 and traction ropes 400 to ensure that the traction ropes 400 will not be overloaded or broken; when the distance between the ship 200 and the power supply vehicle decreases, the redundant cables 500 and traction ropes 400 are automatically retracted. When the driver is driving on the power supply vehicle, he can not only control the heading and speed of the ship, but also control the automatic retractable rack, thereby controlling the use length of the cables 500 and traction ropes 400.

[0069] When the driving mechanism is set on the ship, the ship and the power supply vehicle are connected by communication. The driver sends the speed control signal to the power supply vehicle through the driving mechanism on the ship to adjust the running speed of the power supply vehicle. At the same time, the driving mechanism on the ship controls the steering gear on the ship through the controller to control the heading of the ship. In addition, the retraction and release of the cable 500 and the traction rope 400 can also be controlled by communication control. On this basis, a communication module is provided on the power supply vehicle, and the controller 130 is also connected to the ship 200 or the terminal by communication; wherein the controller 130 is also used to receive the control instructions sent by the ship 200 or the terminal, and control the speed of the on-board traction motor 123 according to the control instructions to adjust the running speed of the power supply vehicle.

[0070] By setting up the communication module, the cable 500 and the traction rope 400 can be retracted and released, or the running speed of the power supply vehicle can be controlled.

[0071] Among them, the terminal described in the present application can be a device terminal used by the user, including but not limited to a mobile phone, a computer, a smart wearable device, etc. Of course, the terminal can also be a back-end server, etc. When the controller 130 communicates with the terminal, wireless communication can be used between the two. Since the distance between the ship 200 and the terminal is relatively close, a near-field communication method such as Bluetooth or WIFI communication can be used. When the controller 130 communicates with the ship 200, the controller 130 can be connected to the ship 200 by optical fiber or wirelessly, and when optical fiber communication is used, the optical fiber, the cable 500 and the traction rope can form a composite cable.

[0072] It should be noted that when the terminal is used to control the ship, it is also possible to choose not to set up a driving mechanism on the ship and the power supply vehicle, but to use the terminal for control, so that the driver can be on the ship or the power supply vehicle or directly control remotely. Of course, it is also possible to choose to set up a driving mechanism on the ship or the power supply vehicle, and then use the driving mechanism and the terminal to jointly control the ship's heading and speed, the length of the cable and the traction rope, etc., which is not limited here.

[0073] That is, in this application, the power supply vehicle includes a communication module, and the communication module is connected to the controller 130. When communicating with the power supply vehicle through a terminal, and the terminal is a mobile phone, the operator can send instructions to the power supply vehicle through the mobile phone on the ship according to the current working conditions. For example, if there is a reef in front of the ship and it needs to be avoided, if the ship 200 needs to run in a direction away from the power supply vehicle, the operator can send instructions to the power supply vehicle through the mobile phone, so that the power supply vehicle can release a longer cable 500 and a towing rope 400, and command the steering gear to turn to cooperate. Of course, when the ship 200 needs to run close to the power supply vehicle, the operator can also send instructions to the power supply vehicle through the mobile phone, so that the power supply vehicle can retract the excess cable 500 and the towing rope 400, and the steering gear can turn to cooperate.

[0074] Alternatively, when the operator determines, based on the current operating conditions, that the ship 200 is running at a high speed and needs to reduce the speed, he or she may send a deceleration command to the power supply vehicle via a mobile phone, and the power supply vehicle reduces the running speed. Since the power supply vehicle drives the ship 200, when the speed of the power supply vehicle is reduced, the speed of the ship 200 is also reduced synchronously.

[0075] Of course, if the ship 200 is provided with a control device, the ship 200 can also be used to communicate with the power supply vehicle directly. For example, although the ship 200 is not provided with a traction power system, it is still provided with a driving mechanism. By operating the driving mechanism, corresponding instructions can be sent to the power supply vehicle and the steering gear, thereby controlling the speed of the power supply vehicle and the heading of the ship, and controlling the retraction and release of the traction rope 400, etc. When the ship 200 is used to communicate with the power supply vehicle, wired communication such as optical fiber can be used. On this basis, the ship 200 and the power supply vehicle are connected through optical fiber, cable 500 and traction rope 400. In one implementation, the three cables can be integrated into one cable to reduce complexity.

[0076] In the present application, the power supply vehicle is used for powering the ship 200, mainly for powering lighting, air conditioning and other equipment on the ship 200. Therefore, as an implementation method, the cable adopts a three-phase four-wire system, and the three-phase line voltage of the cable is used for powering the three-phase load, and the three-phase phase voltage of the cable is used for powering the single-phase load.

[0077] In summary, the working principle of the power supply vehicle provided in this application is:

[0078] The flexibility and scalability of the cable are used to connect the ship and the power supply vehicle to adapt to the swaying of the ship in the water and maintain reliable power supply to the ship. The power supply rail 300 is powered by the ground power grid, and the current receiving module 110 of the power supply vehicle draws power from the power supply rail 300. The power taken by the current receiving module 110 supplies power to the traction power module 120, thereby driving the power supply vehicle to operate. At the same time, the power taken by the current receiving module 110 also supplies power to the distribution unit of the ship 200 through the cable, and the distribution unit supplies power to loads such as air conditioning and lighting. During the operation of the power supply vehicle, the power supply vehicle pulls the ship 200 synchronously through the traction rope 400. The traction force of the traction rope 400 and the steering force of the steering gear 220 form a combined force for sailing along the waterway, which is used to adjust the course; by not setting a traction power device on the ship, the ship's own weight can be reduced to the maximum extent, more useful space can be released, and exhaust gas will not be emitted to pollute the environment.

[0079] Based on the above implementation method, the embodiment of the present application also provides a ship 200, which is electrically connected to the above-mentioned current receiving module 110 through a cable 500, and the ship 200 is connected to the above-mentioned power supply vehicle through a traction rope 400; wherein the ship 200 draws electricity from the current receiving module 110 through the cable 500, and the traction power device on the ship 200 is not started; and when the power supply vehicle is running, the ship 200 is used to run synchronously driven by the traction rope 400.

[0080] The ship 200 is detachably connected with the traction rope 400, the cable 500 and the optical cable. That is, under the traction of the power supply vehicle, after the ship 200 arrives at the dock, the traction rope 400, the cable 500 and the optical cable can be removed from the ship 200 and retrieved by the power supply vehicle to facilitate unloading of the ship 200.

[0081] In one implementation, there are also electrical loads on the ship 200, such as air conditioners, lighting lamps, etc. Therefore, please refer to Figure 3 and Figure 4 The ship 200 includes a shipboard power distribution unit 210, which is connected to the current receiving module 110 via a cable; wherein the shipboard power distribution unit 210 is used to obtain power from the current receiving module 110 and then distribute power to the loads on the ship 200.

[0082] In addition, in one implementation, a driving mechanism 140 and a steering gear 220 may also be provided on the ship 200, and both the driving mechanism 140 and the steering gear 220 are communicatively connected to the controller.

[0083] In a specific application, an operator can operate the driving mechanism 140 to send instructions to the power supply vehicle through the driving mechanism 140, for example, to control the retraction and extension of the cable, or to control the running speed.

[0084] Taking the running speed as an example, after the operator sends the target running speed through the driving mechanism 140, the driving mechanism 140 will send the information to the power supply vehicle. At the same time, the heading and speed sensor 230 collects the heading and speed information of the ship 200 in real time. After receiving the target running speed, the controller 130 converts the target running speed and converts it into the corresponding frequency and voltage information to control the operation of the on-board traction inverter 121. On this basis, the controller 130 will also adjust the frequency and voltage information of the on-board traction inverter 121 according to the real-time speed detected by the heading and speed sensor 230, so as to make the target speed consistent with the real-time speed. In addition, the controller can adjust the operation of the steering gear 220 according to the heading information detected in real time by the heading and speed sensor 230, so that the real-time heading matches the target heading.

[0085] Of course, in another implementation, the driving mechanism may not be arranged on the ship, but on the power supply vehicle, such as Figure 3 As shown, the driving mechanism is connected to the controller for communication; the driving mechanism is used to send navigation instructions to the controller, and the controller is used to control the working state of the servo steering gear according to the navigation instructions to adjust the heading of the ship, which will not be elaborated here.

[0086] In one implementation, when the ship and the power supply vehicle communicate via optical fiber, the ship 200 and the towing rope 400, cable 500, and optical fiber are all detachably connected, wherein the cable 500 and the optical fiber are not subjected to force. For example, the ship 200 and the towing rope 400, cable 500, and optical cable are connected in a plug-in manner. When the ship 200 runs to the dock, the towing rope 400, cable 500, and optical cable can be pulled out from the ship 200.

[0087] For example, when transporting cargo from dock X to dock Y, the ship 200 is connected to the towing rope 400, the cable 500, and the optical cable, and the ship 200 draws power from the power supply vehicle through the cable 500, and the power supply vehicle drives the ship 200 to run through the towing rope 400. When arriving at dock Y, the towing rope 400, the cable 500, and the optical cable can be detached from the ship 200. At the same time, when unloading the ship 200, if the ship 200 needs to return from dock Y to dock X, the ship 200 can be connected to the towing rope 400, the cable 500, and the optical cable to run.

[0088] The above-mentioned configuration ensures that there is not only one corresponding relationship among the ship 200, the traction rope 400, the cable 500 and the optical cable, which is more flexible in actual use.

[0089] Based on the above implementation method, an embodiment of the present application also provides an electrified water transport system for a vehicle and tugboat, which includes a cable 500, a traction rope 400, and the above-mentioned power supply vehicle and ship 200. The power supply vehicle is electrically connected to the ship 200 through the cable 500, and supplies power to the ship 200 through the cable 500, and an optical cable is used for communication control.

[0090] In addition, the vehicle-tugboat electrified water transport system also includes a power supply rail 300, a track bridge 600 and a running rail 700. The track bridge 600 is installed on the river bank of the waterway. The running rail 700 and the power supply rail 300 are both installed on the track bridge 600. The power supply vehicle is installed on the running rail 700 and moves along the running rail 700.

[0091] In one implementation, see Figure 7 The rail bridge 600 can be arranged in a ring shape. For example, the rail bridge 600 between the wharf X and the wharf Y is arranged in a ring shape. Then, a first running rail 710 is arranged from the wharf X to the wharf Y, and a second running rail 720 is arranged from the wharf Y to the wharf X. On this basis, when it is necessary to transport goods from the wharf X to the wharf Y, the first running rail 710 can be used, and when it is necessary to transport goods from the wharf Y to the wharf X, the second running rail 720 can be used.

[0092] Furthermore, the ship 200 is detachably connected to the cable 500, the traction rope 400, and the optical cable. Therefore, when the ship 200 arrives at the dock, the cable 500, the traction rope 400, and the optical cable can be detached, and the ship 200 can be flexibly connected to the power supply vehicle according to actual needs.

[0093] Through this setting method, it is not necessary to correspond the number of ships 200 and power supply vehicles, which can reduce a lot of costs when building the system. For example, when transporting goods from Pier X to Pier Y, the power supply vehicle runs along the first running track 710 and drives the ship 200 to Pier Y. When the ship 200 unloads at Pier Y, the power supply vehicle is used to tow other ships 200 on Pier Y to Pier X. Alternatively, the power supply vehicle can run to Pier X by itself through the second running track 720, without towing the ship 200, to achieve the reciprocating use of the power supply vehicle. In this way, a small number of power supply vehicles can be set up, thereby reducing the cost of the entire electrified water transport system while meeting the transportation needs. For example, when there are 10 ships 200, only five power supply vehicles can be used.

[0094] Therefore, the working principle of the vehicle tugboat electrification water transport system provided by this application is:

[0095] The softness and scalability of the cable are used to connect the ship 200 and the power supply vehicle to adapt to the swaying of the ship in the water and maintain reliable power supply to the ship. The ship 200 and the power supply vehicle are connected through a cable 500 and a traction rope 400 (optical fiber is also included when optical fiber communication is required). The power supply vehicle supplies power to its traction power module 120 to provide power for its own operation, and tows the ship 200 through the traction rope 400 to run synchronously, and then supplies power to the air conditioning, lighting, etc. of the ship 200 through the cable 500. The traction force of the traction rope 400 and the steering force of the steering gear 220 form a combined force for sailing along the waterway, which is used to adjust the course.

[0096] In one implementation, each power supply vehicle is provided with a corresponding cable 500 and a traction rope 400 (optical fiber is also included when optical fiber communication is required). When the ship 200 needs to depart from the dock, the ship 200 is connected to the power supply vehicle at the front of the rail bridge 600 and operates. Optionally, at the dock, the power supply vehicles are arranged in order, and when the cable 500 and the traction rope 400 are separated, the power supply vehicle can retract the cable 500 and the traction rope 400. When the ship 200 needs to depart from the dock, for example, the ship 200 needs to depart from the dock Y, and at this time the power supply vehicle at the front of the rail bridge 600 is the power supply vehicle a, then the power supply vehicle a is controlled to put down the cable 500 and the traction rope 400, and connect the cable 500 and the traction rope 400 to the ship 200. After arriving at the dock X, the cable 500 and the traction rope 400 are separated from the ship 200.

[0097] Through the electrified water transport system provided in the present application, the use of the power supply vehicle and the ship 200 can be flexibly realized. In practical applications, the call of the ship 200 and the power supply vehicle 100 is more convenient.

[0098] In summary, the present application provides a power supply vehicle, a ship and a vehicle tugboat electrified water transport system, the power supply vehicle is applied to the vehicle tugboat electrified water transport system, the vehicle tugboat electrified water transport system also includes a cable, a towing rope, a ship and a controller, the power supply vehicle includes a current receiving module and a traction power module, the controller is communicatively connected to the traction power module, the current receiving module is electrically connected to the traction power module and the power supply rail respectively, the current receiving module is also electrically connected to the ship through a cable, and the power supply vehicle and the ship are also mechanically connected through a towing rope; wherein the current receiving module is used to take current from the power supply rail, and to supply power to the traction power module and to supply power to the ship through the cable; the traction power module is used to drive the power supply vehicle to run along the extension direction of the power supply rail; the power supply vehicle is used to drive the ship to run synchronously through the towing rope during operation, and the traction power device is not started on the ship. On the one hand, since in the present application, the power supply vehicle is used to supply power to the ship while driving the ship to run synchronously when the power supply vehicle is running, there is no need to arrange a power system on the ship, which saves the layout cost of the vehicle tugboat electrified water transport system as a whole. On the other hand, since there is no power system on the ship, it not only replaces the internal combustion engine and solves the problem of environmental pollution, but also does not have energy systems such as large batteries, making the ship's electrical system as simple and light as possible. Therefore, the ship can release more dead weight and effective space, and the transportation efficiency is higher. At the same time, power supply vehicles towing ships can form new industries and service industries.
