Description

Technical Field

[0001] This application relates to the field of cable car technology, and in particular to a marine charging device with high stability. 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 adding fuel 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. The charging cable connects to the vessel for charging. However, the charging cable is heavy and usually quite long, requiring it to be transported from the power source to the vessel using a trolley for connection. During charging, the vessel's movement in the water can cause the trolley to sway, pulling on the cable and resulting in instability. This can lead to the cable coming loose and affecting charging efficiency. Utility Model Content

[0004] To improve charging stability, this application provides a marine charging device with higher stability.

[0005] The marine charging device with high stability provided in this application adopts the following technical solution:

[0006] A marine charging device with high stability includes a vehicle body, a charging cable on the vehicle body, several wheels on the bottom of the vehicle body, and support rods at the four corners of the vehicle body. The support rods are vertically slidably connected to the vehicle body. When the support rod is at its uppermost position, the bottom of the support rod is higher than the bottom of the wheels. When the support rod is at its lowermost position, the bottom of the support rod is lower than the bottom of the wheels.

[0007] By adopting the above technical solution, the vehicle body moves along the charging cable, thereby connecting the power supply on the ship and at the dock for charging. During vehicle movement, the support rod is at the top, suspended above the ground to avoid affecting the vehicle's movement. When the vehicle reaches the corresponding position, the support rod lowers, its lower end contacting the ground and lifting the vehicle body, causing the wheels to detach from the ground and suspend above it. At this point, the vehicle body is connected to the ground via the support rod, and the wheels are suspended in the air. When the ship pulls the vehicle body via the charging cable, the overall stability of the vehicle body is strong and it is not easily moved, thus ensuring the stability of the charging process.

[0008] Preferably, the two ends of the vehicle body are respectively horizontally rotatably connected to telescopic screws, the two ends of the telescopic screws have opposite thread directions, the two ends of the telescopic screws are respectively threaded to support blocks, and the support rod is installed at the end of the support block.

[0009] By adopting the above technical solution, the telescopic screw rotates, and the two support blocks move closer to or further away from the vehicle body simultaneously, thereby adjusting the position of the support rod and facilitating its support.

[0010] Preferably, a connecting rod is rotatably connected to the bottom of the vehicle body. The connecting rod is perpendicular to the telescopic screw, and two telescopic screws are located at both ends of the connecting rod. The middle position of the telescopic screw is connected to the end of the connecting rod through a bevel gear pair.

[0011] By adopting the above technical solution, when one of the telescopic screws rotates, it drives the other telescopic screw to rotate synchronously through the linkage rod, that is, the four support rods extend or retract synchronously, which is convenient to use.

[0012] Preferably, a connecting cylinder is rotatably connected inside the support block, and the support rod passes through the connecting cylinder and is threadedly connected to the connecting cylinder.

[0013] By adopting the above technical solution, the connecting cylinder rotates, driving the support rod to move up and down, lifting or lowering the vehicle body. The structure is stable and easy to use.

[0014] Preferably, a connecting rod is connected between the two connecting cylinders, the connecting rod being parallel to the telescopic screw, and the connecting rod being connected to the connecting cylinders via a bevel gear pair.

[0015] By adopting the above technical solution, two support rods on the same telescopic screw are connected by a connecting rod. When one connecting cylinder rotates, the other connecting cylinder rotates synchronously under the transmission of the connecting rod, so that the two support rods extend or retract synchronously, ensuring the balance of the vehicle body when it is lifted or lowered.

[0016] Preferably, the connecting rod includes outer rods at both ends and an inner rod between the two outer rods, the inner rod and the outer rods being slidably connected, and the inner rod being rotatably connected to the bottom of the vehicle body.

[0017] By adopting the above technical solution, the position of the support rod will be adjusted and changed during the sliding process of the support block, and the telescopic deformation of the connecting rod ensures that it will not interfere with the sliding of the support rod.

[0018] Preferably, the outer rod and the inner rod are slidably connected by a spline.

[0019] By adopting the above technical solution, the outer rod can slide along the inner rod, and the outer rod and the inner rod can also rotate synchronously to achieve transmission.

[0020] Preferably, the bottom of the vehicle body is rotatably connected to a movable rod parallel to the connecting rod, with two connecting rods located at both ends of the movable rod, and the ends of the movable rod being connected to the middle position of the inner rod via a bevel gear pair.

[0021] By adopting the above technical solution, the connecting rod drives the support rods at both ends of the connecting rod, so that the support rods at both ends of the connecting rod can rise and fall synchronously. The movable rod drives the two connecting rods, so that the four support rods can rise and fall simultaneously, ensuring the stability of the vehicle body during the upgrade process.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] By setting up support rods, when the vehicle moves to the ship, the support rods lift the vehicle body, so that the wheels are suspended above the ground, and the vehicle body is supported on the ground by the support rods, thereby improving the stability of the vehicle body.

[0028] The present application will now be described in further detail with reference to all accompanying drawings.

[0029] Example

[0030] This application discloses a marine charging device with strong stability, referring to... Figure 1 and Figure 2 The system includes a vehicle body 1, on which a charging cable 2 for charging the ship is wound. One end of the charging cable 2 is connected to the power supply on the dock, and the other end is connected to the ship, thereby enabling the ship to be charged.

[0031] Reference Figure 1 and Figure 2The vehicle body 1 has four wheels 3 at its bottom for driving its movement. Support rods 4 are located at each of the four corners of the vehicle body 1, and these support rods 4 are vertically slidably connected to the vehicle body 1. When the support rod 4 is at its highest position, its bottom is higher than the bottom of the wheels 3, and it is suspended above the ground. The vehicle body 1 remains in contact with the ground via the wheels 3, ensuring normal movement. When the support rod 4 is at its lowest position, its bottom is lower than the bottom of the wheels 3, thus lifting the vehicle body 1 and detaching the wheels 3 from the ground, supporting and fixing the vehicle body 1 to ensure stability during charging.

[0032] Reference Figure 1 and Figure 2 At the bottom of the vehicle body 1, two parallel telescopic screws 5 are horizontally rotatably connected to each other. A connecting rod 7, perpendicular to the telescopic screws 5 and rotatably connected to the vehicle body 1, is provided between the two telescopic screws 5. The two telescopic screws 5 are located at opposite ends of the connecting rod 7. The end of the connecting rod 7 is connected to the middle position of the telescopic screw 5 via a bevel gear pair. When one telescopic screw 5 rotates, the connecting rod 7 drives the other telescopic screw 5 to rotate synchronously.

[0033] Reference Figure 1 and Figure 2 The threads at both ends of the telescopic screw 5 are arranged in opposite directions, and each end of the telescopic screw 5 is threadedly connected to a support block 6. A connecting cylinder 8 is rotatably connected inside the support block 6, and four support rods 4 are respectively connected to four support blocks 6, with the support rods 4 passing through the connecting cylinder 8 and threadedly connected to the connecting cylinder 8. The rotation of the connecting cylinder 8 causes the support rods 4 to move up and down along the support block 6. As the telescopic screw 5 rotates, the four support blocks 6 move synchronously closer to or further away from the vehicle body 1, thereby adjusting the support position of the support rods 4 and improving the stability of the support rods 4 in supporting the vehicle body 1.

[0034] Reference Figure 1 and Figure 2 A connecting rod 9, rotatably connected to the vehicle body 1, is provided between two support blocks 6 connected to the same telescopic screw 5. The connecting rod 9 includes outer rods 10 at both ends and an inner rod 11 between the two outer rods 10. The inner rod 11 and the outer rods 10 are slidably connected by a spline, and the inner rod 11 is rotatably connected to the bottom of the vehicle body 1. When the support blocks 6 slide along the telescopic screw 5, the connecting rod 9 can extend and retract to avoid interference.

[0035] Reference Figure 1 and Figure 2 Two outer rods 10 are connected to two support blocks 6 respectively, and the ends of the outer rods 10 are connected to the connecting cylinders 8 through bevel gear pairs. When one of the connecting cylinders 8 rotates, the connecting rod 9 drives the other connecting cylinder 8 to rotate synchronously, so that the two support rods 4 on the same telescopic screw 5 can be raised and lowered synchronously, thereby lifting or lowering the vehicle body 1 and ensuring the stability of the vehicle body 1.

[0036] Reference Figure 1 and Figure 2 The bottom of the vehicle body 1 is rotatably connected to a movable rod 12 parallel to the connecting rod 9. Two connecting rods 9 are located at the two ends of the movable rod 12, and the ends of the movable rod 12 are connected to the middle position of the inner rod 11 through a bevel gear pair. When one of the connecting rods 9 rotates, the movable rod 12 drives the other connecting rod 9 to rotate synchronously, thereby causing the four support rods 4 to rise and fall synchronously. This allows the vehicle body 1 to be lifted or lowered simultaneously from the four corners, ensuring the stability of the vehicle body 1.

[0037] The implementation principle of a highly stable marine charging device according to an embodiment of this application is as follows: After the ship approaches the dock, the support rod 4 is raised, and the vehicle body 1 contacts the ground through the wheels 3, which drive the vehicle body 1 to move. After the vehicle body 1 moves to the corresponding position, the support rod 4 is lowered, and the lower end of the support rod 4 contacts the ground, thereby lifting the vehicle body 1 and causing the wheels 3 to detach from the ground and suspend above the ground. At this time, the vehicle body 1 is connected to the ground through the support rod 4, and the wheels 3 are suspended in the air. When the ship pulls the vehicle body 1 through the charging cable 2, the overall stability of the vehicle body 1 is strong and it is not easy to move, thus ensuring the stability of the charging process.

[0038] 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.
