Description

Technical Field

[0001] This application relates to the field of cable vehicle technology, and in particular to a marine charging vehicle. Background Technology

[0002] Port service vessels are a general term for ships that specialize in port operations. Currently, in order to save port costs and reduce pollution from harmful substances, many port service vessels have changed from refueling to generate electricity after docking to charging via onshore charging devices.

[0003] Traditional marine charging equipment is bulky and typically uses a fixed power source at the dock with a long charging cable pre-installed on it. The ship is then connected and charged via this cable. However, the charging cable is heavy and usually quite long, requiring it to be dragged from the power source to the ship. This is usually done manually, making it inconvenient to use. Utility Model Content

[0004] To facilitate charging, this application provides a marine charging vehicle.

[0005] The marine charging vehicle provided in this application adopts the following technical solution:

[0006] A marine charging vehicle includes a vehicle body, a winding frame rotatably connected to the vehicle body at the rear of the vehicle body, a telescopic frame located at the front of the vehicle body, an input cable wound on the winding frame, an output cable on the telescopic frame, a charging connector for connecting to a power source at one end of the input cable, a connection between the other end of the input cable and the output cable, and a charging plug for connecting to a ship at the end of the output cable away from the input cable.

[0007] By adopting the above technical solution, when charging is needed, the charging connector is plugged into the power supply at the dock, and the vehicle moves towards the ship. During the movement, the winding frame rotates, continuously unwinding the input cable until the vehicle reaches the ship. The telescopic frame extends and retracts, aligning the charging plug with the charging port on the ship, and the charging plug is inserted into the charging port to begin charging. The vehicle's design separates the charging cable and power supply, and the moving vehicle facilitates cable winding and unwinding, making charging convenient.

[0008] Preferably, the input cable and the output cable are provided with a plurality of cables.

[0009] Preferably, the input cable and the output cable are integrated into a single cable at their closest points, and the input cable and the output cable are connected by a connecting cable embedded in the vehicle body.

[0010] By adopting the above technical solution, the input cable and the output cable are connected by a connecting cable embedded in the vehicle body, thereby simplifying the external structure of the vehicle body.

[0011] Preferably, a rotating frame is rotatably connected to the end of the telescopic frame, the rotating frame is rotatably connected to the telescopic frame via a rotating rod, a rotating motor is installed on the telescopic frame, the rotating motor is connected to the rotating rod, and the charging plug is located on the rotating frame.

[0012] By adopting the above technical solution, the rotating motor starts and drives the rotating frame to rotate, thereby adjusting the direction of the charging plug to facilitate connection with the ship.

[0013] Preferably, a clamping rod parallel to the rotating rod is fixed on the rotating frame, and several clamping wheels rotate on the clamping rod. A rotating wheel is rotatably connected to the rotating rod, and the rotating wheel and the clamping wheel correspond one-to-one. The number of rotating wheels is the same as the number of output cables, and the end of the output cable is clamped between the rotating wheel and the clamping wheel.

[0014] By adopting the above technical solution, the rotating wheel and the clamping wheel cooperate to clamp and limit the output cable, thereby improving the stability of the charging plug and facilitating the connection of the charging plug to the ship.

[0015] Preferably, a limiting frame is installed on the vehicle body at the rear of the vehicle. The limiting frame is located on the side of the winding frame away from the telescopic frame. The limiting frame is provided with an arc-shaped limiting plate. A limiting rod is fixed on the limiting frame above the limiting plate. The end of the input cable is located between the limiting plate and the limiting rod. The distance between the limiting rod and the limiting plate is greater than the diameter of the input cable but less than the diameter of the charging connector.

[0016] By adopting the above technical solution, the limiting frame limits the input cable, and the limiting rod and limiting plate work together to restrict the position of the input cable, preventing tangling and knotting. Furthermore, the limiting rod restricts the charging connector, preventing it from retracting into the winding frame.

[0017] Preferably, a plurality of limiting rollers are rotatably connected to the limiting frame, and limiting gaps are formed between the limiting rollers. The number of limiting gaps is consistent with the number of input cables, and the end of the input cable passes through the limiting gap.

[0018] By adopting the above technical solution, the limiting roller limits the input cable, and when the input cable is wound up and unwound, the input cable contacts the limiting roller and drives the limiting roller to rotate. The friction between the input cable and the limiting roller is small, and the winding and unwinding of the input cable is more convenient.

[0019] Preferably, the telescopic frame includes a seat mounted on the vehicle body, a telescopic rod rotatably connected to the seat, the telescopic rod including an outer rod and an inner rod slidably connected, both the outer rod and the inner rod being provided with guide frames, the output cable passing through the guide frames, and the output cable including a buffer portion located between the two guide frames.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] 1. The charging cable and power supply are separated by the vehicle body, and the moving vehicle body facilitates the winding and unwinding of the cable, making charging convenient. Attached Figure Description

[0026] The present application will be further described in detail below with reference to all the accompanying drawings.

[0027] Example

[0028] This application discloses a marine charging vehicle, referring to... Figures 1 to 2 The vehicle comprises a body 1. The body 1 has wheels at its bottom, and a cable winder 2 at the rear and a telescopic frame 3 at the front. An input cable 4 is wound on the cable winder 2, and an output cable 5 is mounted on the telescopic frame 3. One end of the input cable 4 has a charging connector 6 for connecting to a power source, and the other end of the input cable 4 is connected to the output cable 5. The end of the output cable 5 away from the input cable 4 has a charging plug 7 for connecting to the ship. The rear of the body 1 is near a power source on the dock. When the ship approaches the dock, the charging connector 6 connects to the power source on the dock. The body 1 moves towards the ship until it reaches the ship, at which point the telescopic frame 3 extends and retracts, bringing the output cable 5 closer to the ship until the charging plug 7 is inserted into the ship, initiating charging.

[0029] Reference Figures 1 to 2There are four input cables 4 and four output cables 5. The ends of the input cables 4 and 5, close to each other, are integrated into a single cable, and they are connected by a connecting cable 8, which is embedded within the vehicle body 1. The upper surface of the vehicle body 1 only displays the input cables 4 and 5, resulting in a cleaner appearance. Furthermore, the input cables 4 and 5 are not directly connected but are buffered by the connecting cable 8. Before charging, the vehicle body 1 undergoes two main actions: movement and movement of the telescopic frame 3. When the vehicle body 1 moves, the input cables 4 are unwound, while the output cables 5 remain stationary. When the telescopic frame 3 moves, the output cables 5 extend, while the input cables 4 remain stationary. The connecting cable 8 separates the input cables 4 and 5, making them relatively independent, minimizing the impact of one cable's movement on the other, thus ensuring overall stability.

[0030] Reference Figures 1 to 2 A limiting frame 15 is installed on the vehicle body 1 at the rear of the vehicle. The limiting frame 15 is located on the side of the winding frame 2 away from the telescopic frame 3. The limiting frame 15 is provided with an arc-shaped limiting plate 16. A limiting rod 17 is fixed on the limiting frame 15 above the limiting plate 16. The end of the input cable 4 is located between the limiting plate 16 and the limiting rod 17. The distance between the limiting rod 17 and the limiting plate 16 is greater than the diameter of the input cable 4 but less than the diameter of the charging connector 6. Several limiting rollers 18 are rotatably connected to the limiting frame 15. Limiting gaps are formed between the limiting rollers 18. The number of limiting gaps is the same as the number of input cables 4. The end of the input cable 4 passes through the limiting gap. The limiting roller 18 limits the input cable 4, and when the input cable 4 is wound up and unwound, the input cable 4 contacts the limiting roller 18 and drives the limiting roller 18 to rotate. The friction between the input cable 4 and the limiting roller 18 is small, and the winding and unwinding of the input cable 4 is relatively convenient.

[0031] Reference Figures 1 to 2 The telescopic frame 3 includes a seat 19 mounted on the vehicle body 1. A telescopic rod 20 is rotatably connected to the seat 19. The telescopic rod 20 includes an outer rod 21 and an inner rod 22 that are slidably connected. Guide frames 23 are provided on both the outer rod 21 and the inner rod 22. The output cable 5 is routed around the guide frames 23. The output cable 5 includes a buffer portion 24 located between the two guide frames 23. When the telescopic frame 3 extends or retracts, the cable at the buffer portion 24 gradually shortens, thereby meeting the extension and retraction requirements of the telescopic frame 3.

[0032] Reference Figures 1 to 2A rotating frame 9 is rotatably connected to the end of the telescopic frame 3. The rotating frame 9 is rotatably connected to the telescopic frame 3 via a rotating rod 10. A rotating motor 11 is installed on the telescopic frame 3 and is connected to the rotating rod 10. The charging plug 7 is located on the rotating frame 9. When the rotating motor 11 is started, it drives the rotating frame 9 to rotate, thereby adjusting the direction of the charging plug 7 for easy connection to the ship.

[0033] Reference Figures 1 to 2 A clamping rod 12, parallel to the rotating rod 10, is fixed on the rotating frame 9. Several clamping wheels 13 rotate on the clamping rod 12. A rotating wheel 14 is rotatably connected to the rotating rod 10. The rotating wheels 14 and clamping wheels 13 correspond one-to-one. The number of rotating wheels 14 is the same as the number of output cables 5, and the end of the output cable 5 is clamped between the rotating wheels 14 and the clamping wheels 13. The rotating wheels 14 and clamping wheels 13 cooperate to clamp and limit the output cable 5, thereby improving the stability of the charging plug 7 and facilitating the connection of the charging plug 7 to the ship.

[0034] The implementation principle of a marine charging vehicle according to an embodiment of this application is as follows: When the ship approaches the dock, the charging connector 6 connects to the power supply on the dock. The vehicle body 1 moves towards the ship, and the input cable 4 on the winding frame 2 begins to unwind until it reaches the ship. The telescopic frame 3 extends and retracts, causing the output cable 5 to approach the ship until the charging plug 7 is inserted into the ship, and charging begins.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
