Description

Technical Field

[0001] This invention belongs to the technical field of shore power cable transmission devices, specifically relating to a multi-stage telescopic shore power cable transmission device for charging ships at cruise and yacht marinas. Background Technology

[0002] As people's demands for a better living environment increase, energy conservation and emission reduction are becoming increasingly urgent. Using shore power is the most effective way to reduce pollution from ships docked at port. When ships are in port, shore power can enable them to achieve "zero emissions." The development and application of port shore power technology can effectively reduce pollution emissions from docked ships and improve the greening level of ports. The introduction and application level of marine shore power technology has also become one of the important indicators for building green ports.

[0003] Shore power for ships is a crucial component of building green, energy-efficient, and smart ports, and is receiving increasing attention. In recent years, as shore power systems have been increasingly applied to various types of ports, the safe and efficient connection between these systems and the power systems of berthed ships has become an important research topic. For a long time, berthed ships have relied on fuel-powered auxiliary engines to generate their own electricity, leading to high energy consumption and pollution in ports and surrounding areas. my country is actively advocating a green economic development model that emphasizes energy conservation, emission reduction, and low-carbon transportation. In recent years, major ports have successively conducted research on installing shore power supplies for ships to provide clean energy (shore power) for berthed vessels, aiming to save fuel costs, reduce port emissions, lower noise pollution, and achieve environmental protection goals.

[0004] With the increasing number of ships of various types docking at major ports every day, the pollution in these port areas has reached a point where it must be taken seriously. In recent years, thanks to strong government advocacy, shore power supply technology for ships has flourished. Therefore, researching a stable and reliable shore power cable transmission device can meet the current urgent needs of ports. The shore power cable transmission device will play a significant role in shore power connection when ships dock. In the shore power cable connection system, the transmission of shore power cables is an indispensable link. The traditional connection method involves workers dragging the shore power cables from the ship to the shore and manually connecting them to the shore power box or distribution cabinet. When the ship departs, the shore power cables are then manually wound up again. This method is not only time-consuming and labor-intensive but also poses safety hazards.

[0005] Existing technologies include a method using a barge in conjunction with a surface-to-water robot to deliver shore power cables to receiving vessels. The barge carries the power supply, while the surface-to-water robot is equipped with a shore power cable securing device, a lifting device, and a lateral conveying device, enabling the securing, lifting, and transmission of the shore power cable. The process involves manually attaching the shore power cable connector to the surface-to-water robot's securing device on the barge, remotely controlling the robot to the receiving vessel, and then using its lifting device to raise the shore power cable to a horizontal position on the deck. The cable is then laterally conveyed to the vessel's deck, where personnel connect the connector to begin supplying power. While this method achieves effective shore power cable transmission, it suffers from low efficiency, can only transmit shore power to one vessel at a time, and has high maintenance costs for the surface-to-water robot. Summary of the Invention

[0006] The purpose of this invention is to address the problems existing in the prior art by providing a multi-stage telescopic shore power cable transmission device for charging ships at cruise and yacht marinas.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A multi-stage telescopic shore power cable delivery device for charging cruise and yacht marina vessels includes a pontoon. A base arm is laterally mounted on the pontoon via a first support column. The front end of the base arm is connected to multiple stages of telescopic arms via multiple hydraulic telescopic mechanisms. The pontoon also includes a control room housing a power supply and an electrical control cabinet. An electric reel is also mounted on the pontoon, on which multiple shore power cables are wound. One end of each shore power cable is connected to the power supply, and the other end is laid along the length of the telescopic arms. Each shore power cable has a charging connector at its end, and each stage of the telescopic arm has a charging connector attached to its end. The electrical control cabinet is connected to the multiple hydraulic telescopic mechanisms and the electric reel, respectively, for controlling the reel's winding and unwinding.

[0009] This invention features a multi-stage telescopic arm at the front end of a base arm. Multiple hydraulic telescopic mechanisms, controlled by an electrical control cabinet, drive the telescopic arms to extend and retract. Each telescopic arm has a charging connector at its end. An electric reel winds up and unwinds shore power cables, which, in conjunction with the multiple hydraulic telescopic mechanisms, drives the telescopic arms to extend and retract. This allows for the simultaneous transmission of shore power cables to multiple berthed vessels, significantly improving shore power cable delivery efficiency and saving on shore power operating costs.

[0010] Preferably, a second support column is installed above the base arm. The top of the second support column is equipped with multiple pulleys, each with a cable wound around it. One end of each cable is connected to the end of the multi-stage telescopic arm, and the other end passes over the transition pulley at the tail end of the base arm and is wound onto a winding mechanism, which is connected to the electrical control cabinet. By using cables, the extension and retraction of the multi-stage telescopic arm can be coordinated, thereby reducing the load on the conveying device and improving its stability.

[0011] Furthermore, a tension sensor is installed on the pulley, and the tension sensor is connected to the electrical control cabinet. During the winding and unwinding process of the winding mechanism, the tension sensor detects the tension of the cable in real time. When the tension is greater than the maximum value of the preset range, it indicates that the cable is too tight, and the cable needs to be unwound appropriately to prevent the cable from breaking. When the tension is less than the minimum value of the preset range, it indicates that the cable is under too little force and the cable has not played a good role in reducing the load on the conveying device. In this case, the cable needs to be wound up appropriately to reduce the load on the conveying device.

[0012] Specifically, the barge is equipped with stairs, and the control room is located at the top of the stairs. By placing the control room at a high position, the operators have a wider field of vision when controlling the shore power cable transmission.

[0013] Specifically, the multi-stage telescopic arm adopts a triangular truss structure, which greatly reduces the weight of the device and improves its stability; the bottom inner side of both the base arm and the multi-stage telescopic arm is equipped with rails, and the bottom outer side of the multi-stage telescopic arm is equipped with rollers that match the corresponding rails. The multi-stage telescopic arm and the base arm achieve telescopic movement through the cooperation of rails and rollers.

[0014] Specifically, both the inner bottom of the multi-stage telescopic arm and the base arm are equipped with rollers to support the shore power cable. By setting rollers, wear during the shore power cable transportation process can be reduced, and the shore power cable transportation can be made smoother.

[0015] Specifically, the outer wall of the first support column is provided with multiple stiffening plates, which serve as reinforcing ribs and improve the strength of the first support column.

[0016] Specifically, the control room is also equipped with a remote control receiver, which is connected to the electrical control cabinet; the remote control receiver is also wirelessly connected to the remote control transmitter. This allows for remote control of the shore power cable delivery device to automatically reel in and out, making operation more flexible. One person can simultaneously control the operation of multiple shore power cable delivery devices, improving work efficiency.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention sets up a multi-stage telescopic arm at the front end of the base arm, and drives the multi-stage telescopic arm to extend and retract by multiple hydraulic telescopic mechanisms controlled by the electrical control cabinet. Each telescopic arm has a charging connector at the end. The electric reel winds up and down the shore power cable in conjunction with the multiple hydraulic telescopic mechanisms to drive the multi-stage telescopic arm to extend and retract, which can transmit shore power cables to multiple ships berthed together at the same time, greatly improving the shore power cable transmission efficiency and saving shore power operating costs; (2) The present invention sets up a second support column above the base arm to install a cable, which can be used in conjunction with the extension and retraction of the multi-stage telescopic arm, thereby reducing the load on the conveying device and improving the stability of the device; (3) By installing a tension sensor on the pulley to detect the tension of the cable during the winding and unwinding process of the winding mechanism, the winding and unwinding of the cable is adjusted according to the tension on the cable, so as to avoid the cable breaking due to excessive load or failing to share the load of the conveying device due to insufficient load.

[0027] Example

[0028] like Figures 1 to 4As shown, this embodiment provides a multi-stage telescopic shore power cable transmission device for charging ships at cruise and yacht docks, including a pontoon 1. A base arm 3 is horizontally mounted on the pontoon 1 via a first support column 2. The front end of the base arm 3 is connected to a first telescopic arm 4, a second telescopic arm 5, and a third telescopic arm 6 via three hydraulic telescopic mechanisms (not shown in the figure). The first telescopic arm 4 is slidably connected to the base arm 3, the second telescopic arm 5 is slidably connected to the first telescopic arm 4, and the third telescopic arm 6 is slidably connected to the second telescopic arm 5. The above three sliding connections are respectively supported by three hydraulic telescopic mechanisms. The telescopic boom is driven by a retracting mechanism; the pontoon 1 is also equipped with a control room 7, which contains a power supply and an electrical control cabinet; the pontoon 1 is also equipped with an electric reel 20, on which multiple shore power cables are wound, one end of which is connected to the power supply, and the other end of which is laid along the length of the telescopic boom; the end of the shore power cable is equipped with a charging connector 8, and each telescopic boom has a charging connector 8 at its end; the electrical control cabinet is connected to three hydraulic telescopic mechanisms and the electric reel 20 respectively, and is used for the retraction and extension control of the electric reel 20.

[0029] This embodiment sets up a three-stage telescopic arm at the front end of the base arm 3. The three-stage telescopic arm is driven to extend and retract by three hydraulic telescopic mechanisms controlled by the electrical control cabinet. Each stage of the telescopic arm is equipped with a charging connector 8 at its end. The electric reel 20 winds up and unwinds the shore power cable. With the help of the three hydraulic telescopic mechanisms, the three-stage telescopic arm can extend and retract, which can simultaneously transmit shore power cables to three ships 19 that are moored together. This greatly improves the efficiency of shore power cable transmission and saves shore power operating costs.

[0030] In this embodiment, the length of each telescopic boom is 18m. After the three telescopic booms are fully extended, they can simultaneously deliver shore power cables to three ships 19 that are moored side by side. Each telescopic boom carries one shore power cable, and the winding and unwinding of the shore power cable is controlled by an electric reel 20.

[0031] Preferably, a second support column 9 is also installed above the base arm 3. The top of the second support column 9 has two pulleys 10, each with a cable 11 wound around it. One end of each cable 11 is connected to the end of the three-stage telescopic arm, and the other end passes over the transition wheel 12 at the tail end of the base arm 3 and is wound onto a winding mechanism 21, which is connected to the electrical control cabinet. By setting the cables 11, the extension and retraction of the three-stage telescopic arm can be coordinated, thereby reducing the load on the conveying device and improving the stability of the device.

[0032] Furthermore, a tension sensor (not shown in the figure) is provided on the pulley 10, and the tension sensor is connected to the electrical control cabinet. During the winding and unwinding process of the winding mechanism 21, the tension sensor detects the tension of the cable 11 in real time. When the tension is greater than the maximum value of the preset range, it indicates that the cable 11 is too tight. At this time, it is necessary to unwind the cable appropriately to prevent the cable 11 from breaking. When the tension is less than the minimum value of the preset range, it indicates that the cable 11 is under too little force and the cable 11 has not played a good role in reducing the load on the conveying device. At this time, it is necessary to wind up the cable appropriately to reduce the load on the conveying device.

[0033] Specifically, the barge 1 is equipped with a staircase 13, and the control room 7 is located at the top of the staircase 13. By placing the control room 7 at a high position, the operator has a wider field of vision when controlling the shore power cable transmission.

[0034] Specifically, the multi-stage telescopic arm adopts a triangular truss structure 14, which greatly reduces the weight of the device and improves its stability; the bottom inner side of the base arm 3 and the multi-stage telescopic arm are provided with rails 15, and the bottom outer side of the multi-stage telescopic arm is provided with rollers 16 that match the corresponding rails 15. The multi-stage telescopic arm and the base arm 3 achieve telescopic movement through the cooperation of the rails 15 and the rollers 16.

[0035] Specifically, both the multi-stage telescopic arm and the base arm 3 are equipped with rollers 17 on their inner bottom sides to support the shore power cable. By setting rollers 17, wear during the shore power cable transportation process can be reduced, and the shore power cable transportation can be made smoother.

[0036] Specifically, the outer wall of the first support column 2 is provided with multiple stiffening plates 18, which serve as reinforcing ribs and improve the strength of the first support column 2.

[0037] Specifically, the control room 7 is also equipped with a remote control receiver, which is connected to the electrical control cabinet; the remote control receiver is also wirelessly connected to the remote control transmitter. This allows for remote control of the automatic cable delivery and take-up / delivery of the shore power cable transmission device, making operation more flexible. One person can simultaneously control the operation of multiple shore power cable transmission devices, improving work efficiency.

[0038] The operation process of the shore power cable transmission device in this embodiment is as follows:

[0039] The vessels 19 awaiting charging are lined up and moored alongside one side of the pontoon 1;

[0040] The three-stage telescopic boom is extended by the control cabinet, while the electric reel 20 and the winding mechanism 21 are controlled to release the wire. The wire release speed of the electric reel 20 matches the extension speed of the telescopic boom. The winding mechanism 21 controls the wire release speed based on the tension of the cable 11 detected in real time by the tension sensor.

[0041] When the three-stage telescopic boom is fully extended, the charging connector 8 at the end of each telescopic boom is located above the three ships 19 to be charged. At this time, the electric reel 20 is controlled to continue releasing the line so that the charging connector 8 reaches the surface of the corresponding ship 19, thereby achieving docking with the power receiving equipment of the ship 19.

[0042] Once all three vessels 19 have completed charging, the electric reel 20 is controlled to begin winding up the cable until the charging connector 8 reaches a certain distance below the end of each telescopic arm and then stops.

[0043] Then, control the retraction of the three-stage telescopic arm, and simultaneously control the electric reel 20 and the winding mechanism 21 to take in the wire. The winding speed of the electric reel 20 matches the retraction speed of the telescopic arm; the winding mechanism 21 controls the winding speed based on the tension of the cable 11 detected in real time by the tension sensor.

[0044] Once the three-stage telescopic boom is fully retracted into the base boom 3, the shore power cable transmission process is completed. By retracting the three-stage telescopic boom into the base boom 3, wind load can be reduced and the stability of the device can be improved.
