Description

Technical Field

[0001] This utility model relates to the field of ship charging technology, specifically an electric tugboat charging device. Background Technology

[0002] Ship docking power connection refers to using land-based power sources to replace the ship's diesel engines when the ship is docked at a pier.

[0003] Specifically, once a ship enters a port, it ceases operation of its onboard engines and connects to a land-based power source to meet its electricity needs. This power supply method is typically supported by a shore power system, which comprises two parts: a port power supply system and a ship's substation system. The port power supply system's power is processed through voltage and frequency conversion before being laid to the dock via high-voltage cables. It is then connected to the ship through a high-voltage junction box, and after further voltage transformation at the ship's onboard substation, it effectively supplies power to the vessel.

[0004] Currently, most ships connect to power ashore by using cable reels on board to lower cables to the shore, then manually dragging the cables to the shore power box. This process involves manually pulling the cables from the shore to the ship for power connection. Due to the significant tidal difference between the ship and the shore during berthing, this requires a large number of personnel, a high degree of coordination, is time-consuming and labor-intensive, and is difficult and unsafe. Summary of the Invention

[0005] The purpose of this invention is to provide an electric tugboat charging device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0023] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0024] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0025] Please see Figures 1-3 In this embodiment of the utility model, an electric tugboat charging device is installed on the breast wall at the front edge of the dock, including a support frame 1, a lever arm 2, a control box 3, a conveying arm 4, a cable 7, a first guide member and a second guide member.

[0026] For details, please refer to the following: Figure 1 and Figure 2 ,include;

[0027] A support frame 1 and a lever arm 2 rotatably mounted on the support frame 1, wherein a conveying arm 4 is fixedly mounted on the lever arm 2;

[0028] Cable 7, one end of which is connected to control box 3, and the other end of which passes sequentially around a first guide installed on lever arm 2 and a second guide installed on one end of conveying arm 4, and is equipped with a connector. The cable 7 is wound in opposite directions on the first guide and the second guide.

[0029] The first guide component includes a limiting wheel 6, with two clamping wheels at the end of the limiting wheel 6 to limit the cable 7. The second guide component includes a guide plate 5 with an arc-shaped structure. With the cooperation of the guide plate 5 and the limiting wheel 6, the movement of the cable 7 is guided and limited, and the cable 7 can automatically retract when charging stops.

[0030] It should be noted that a limiting component is provided on one end of the conveying arm 4 to lock the connector of the cable 7, so as to prevent the cable 7 from automatically retracting after charging is finished and disengaging from one end of the conveying arm 4.

[0031] For further solutions to this utility model, please refer to [link / reference]. Figure 1The conveying arm 4 includes a first conveying rod 401 and a second conveying rod 402. The first conveying rod 401 is fixedly connected to the lever arm 2, and the second conveying rod 402 is slidably disposed at the end of the first conveying rod 401 away from the lever arm 2.

[0032] The electric tugboat charging device also includes a control box 3, which communicates with the first drive unit mounted on the support frame 1 and the second drive unit mounted on the conveying arm 4.

[0033] The first driving component includes a motor fixedly mounted on the support frame 1. The motor communicates with the control box 3, and the output shaft of the motor is fixedly connected to the lever arm 2.

[0034] The second driving component includes an electric telescopic rod 8 fixedly installed on the first conveying rod 401. The electric telescopic rod 8 communicates with the control box 3, and the movable end of the electric telescopic rod 8 is fixedly connected to the second conveying rod 402.

[0035] It should be noted that: the control box 3 controls the electric telescopic rod 8 on the first conveying rod 401 and the motor in the support frame 1 respectively. After the electric tugboat enters the port, the control box 3 first sends a signal to the motor to control the electric start-up. When the motor conveying shaft rotates, it drives the power arm 2 to rotate synchronously, so that the conveying arm 4 rotates and extends to the sea side. Then, according to the distance between the plug on the cable 7 and the electric tugboat, the control box 3 sends a signal to the electric telescopic rod 8, and the cylinder rod of the electric telescopic rod 8 extends, which drives the conveying length of the conveying arm 2 to change, so as to adjust the distance between the electric tugboat and the plug on the cable 7, which can more conveniently complete the charging work of the electric tugboat.

[0036] In detail, when not charging, the conveyor arm 4 is parallel to the dock shoreline and does not affect surrounding traffic. When charging is needed, the control box 3 is activated to send a signal to the motor, causing the conveyor arm 4 to rotate 90° and extend to the sea side. Then, based on the distance between the cable 7 on the second conveyor arm 402 and the electric tugboat, a signal is sent to the electric telescopic arm 8 to control the electric telescopic arm 8 to move the second conveyor arm 402 relative to the first conveyor arm 401, conveying the cable 7 to the moored electric tugboat. The cable 7 is then manually connected to the ship's battery for charging by dragging the connector. This allows for remote control of the charging of electric tugboats of different sizes, is unaffected by the large tidal difference between the ship and the shore, requires fewer personnel, is easy for ship and shore personnel to cooperate with, and is highly safe.

[0037] Preferably, the electric tugboat charging device further includes a reinforcing rib 10, which is arranged in an inclined structure. One end of the reinforcing rib 10 is hinged to the first conveying rod 401, and the other end is hinged to the lever arm 2, so as to increase the support stability of the conveying arm 4 and the lever arm 2.

[0038] Preferably, the first conveying rod 401 and the second conveying rod 402 are provided with multiple sets of limiting pulleys 9, and the limiting pulleys 9 are configured with a structure that is concave in the middle and convex at both ends.

[0039] When the cable 7 is being conveyed, it moves relative to the first conveying rod 401 and the second conveying rod 402. The limiting pulley 9 limits the movement of the cable 7.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
