Description

Technical Field

[0001] The present invention relates to the technical field of onshore power systems, and particularly to an on-board onshore power connection device and an on-board onshore power equipment. Background Art

[0002] With the implementation of low-carbon emission reduction in the shipbuilding industry, especially when a ship is berthed at a port, the emission limits at the port terminal are more stringent. Many terminals require the use of onshore power to reduce pollutant emissions in the port. To use onshore power, an onshore power winch device is equipped on the ship to carry the cable and convey the cable to the dock shore to connect to the power system when using onshore power.

[0003] When the molded depth of the ship is relatively low or the dock water level is relatively low, the onshore power winch device on the ship may be lower than the dock. To use onshore power, the cable on the ship can only be manually pulled upward to be conveyed to the shore. The cable is very heavy, and this method is very time-consuming and laborious, and is extremely unfriendly to the crew or shore operators. Summary of the Invention

[0004] The purpose of the present invention is to provide an on-board onshore power connection device and an on-board onshore power equipment, which can improve the convenience of conveying the cable to the shore on the basis of ensuring the hull stability and reduce the labor intensity of the crew.

[0005] To achieve the above purpose, the following technical solutions are provided:

[0006] The on-board onshore power connection device includes:

[0007] A base, which is used to be arranged on the deck of the hull in a liftable manner;

[0008] A winch, which is rotatably arranged on the base. The winch is used to wind the cable, and the cable is used to connect to the power supply system of the port. The cable is wound on the winch in an upward-outgoing rope manner;

[0009] A driving mechanism, which is used to drive the base to lift so that the base is higher than the dock of the port.

[0010] As a preferred technical solution of the above on-board onshore power connection device, the on-board onshore power connection device further includes a bracket corresponding to the winch. The bracket can support the outgoing cable. One end of the bracket is rotatably arranged on the base around a direction parallel to the axial direction of the winch, and the other end of the bracket can extend to the outside of the hull or retract to the inside of the hull.

[0011] As a preferred technical solution of the above on-board onshore power connection device, the on-board onshore power connection device further includes a locking assembly, which can lock or unlock the bracket and the base.

[0012] As a preferred technical solution of the above shipborne shore power connection device, the shipborne shore power connection device further includes a bracket provided on the base, and the bracket includes a guiding structure for guiding the cable.

[0013] As a preferred technical solution of the above shipborne shore power connection device, the guiding structure includes a guiding roller capable of contacting the cable, and the guiding roller is rotatably provided on the bracket.

[0014] As a preferred technical solution of the above shipborne shore power connection device, the driving mechanism includes:

[0015] A folding bracket, which is movably connected between the base and the deck. The folding bracket includes an unfolded state and a folded state. When the folding bracket is in the unfolded state, the height of the base is higher than the dock of the port; when the folding bracket is in the folded state, the base falls on the deck.

[0016] A driving component for driving the folding bracket to switch between the unfolded state and the folded state.

[0017] As a preferred technical solution of the above shipborne shore power connection device, the deck is provided with a groove, the bottom end of the folding bracket is provided in the groove, and the top end of the folding bracket is connected to the base.

[0018] As a preferred technical solution of the above shipborne shore power connection device, the folding bracket includes a first support member and a second support member. The first support member and the second support member are pivotally connected to form an X-shaped structure. The top end of the first support member is pivotally connected to the base, the bottom end of the first support member is slidably connected to the deck, the top end of the second support member is slidably connected to the base, and the bottom end of the second support member is pivotally connected to the deck.

[0019] The driving component is a linear driving component, the linear driving component is rotatably provided on the deck, and the driving end of the driving component is pivotally connected to the top end of the first support member.

[0020] As a preferred technical solution of the above shipborne shore power connection device, the bottom end of the first support member is rollingly connected to the deck; the second support member is rollingly connected to the deck.

[0021] To achieve the above object, a shipborne shore power equipment is further provided, which includes a shipborne power receiving system and the shipborne shore power connection device as described in any one of the above. The shipborne power receiving system can be electrically connected to the power supply system of the port through a cable, and the cable is wound around the reel car.

[0023] For the on-board shore power connection device and on-board shore power equipment of the present invention, the reel is rotatably arranged on the base, and the base is liftably arranged on the deck of the hull. When the hull is docked, the base can be driven to rise by the driving mechanism so that the base can be higher than the dock of the port, thereby facilitating the cable wound around the reel to smoothly lower from the ship to the dock under the action of its own gravity and stiffness, improving the convenience of cable transmission to the shore and reducing the labor intensity of the crew; when the hull is sailing normally, the base is driven to lower by the driving mechanism, and thus the center of gravity of the hull will not be increased, which is beneficial to ensuring the stability of the hull.

[0036] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0037] As Figures 1-4 shown, this embodiment provides a shipborne shore power connection device, which includes a base 1, a cable reel 2, and a driving mechanism 3. The base 1 is used to be disposed on the deck 100 of the hull in a liftable manner; the cable reel 2 is rotatably disposed on the base 1. The cable reel 2 is used for winding a cable, and the cable is used to connect to the power supply system of the port. The cable is wound around the cable reel 2 in an upward rope-out manner; the driving mechanism 3 is used to drive the base 1 to lift, so that the base 1 is higher than the dock of the port.

[0038] In the shipborne shore power connection device of this embodiment, the cable reel 2 is rotatably disposed on the base 1, and the base 1 is liftably disposed on the deck 100 of the hull. When the hull is docked, the driving mechanism 3 can be used to drive the base 1 to rise, so that the base 1 can be higher than the dock of the port, thereby facilitating the cable wound around the cable reel 2 to smoothly drop from the ship to the dock under the action of its own gravity and stiffness, improving the convenience of transporting the cable to the shore, and reducing the labor intensity of the crew; when the hull is sailing normally, the driving mechanism 3 is used to drive the base 1 to lower, and thus the center of gravity of the hull will not be increased, which is beneficial to ensuring the stability of the hull.

[0039] It should be noted that by driving the base 1 to rise through the driving mechanism 3 so that the top surface of the base 1 is higher than the ground of the dock, it can be considered that the base 1 is higher than the dock of the port. The ground of the dock is flush with the ground of the port land. Of course, the ground of the dock can also be lower than the ground of the port land, and the ground of the dock can also be higher than the ground of the port land, which is not limited herein.

[0040] Optionally, the shipborne shore power connection device further includes a bracket 4 corresponding to the cable reel 2. The bracket 4 can support the rope-out cable. One end of the bracket 4 is rotatably disposed on the base 1 around a direction parallel to the axial direction of the cable reel 2, and the other end of the bracket 4 can extend to the outside of the hull or retract to the inside of the hull. It should be noted that the bracket 4 is disposed on one side of the cable reel 2 in a first direction. The first direction is parallel to the deck 100 and perpendicular to the axial direction of the cable reel 2, so that the bracket 4 and the cable reel 2 are correspondingly arranged. When shore power needs to be used when the hull is docked, the bracket 4 is rotated so that the other end of the bracket 4 extends to the outside of the hull, and the rope-out cable is supported by the bracket 4 to avoid friction between the cable and the ship's side of the hull, etc., and to protect the cable; when shore power is not needed, the bracket 4 is rotated so that the other end of the bracket 4 can retract to the inside of the hull, and thus the normal sailing of the hull will not be affected.

[0041] Optionally, the on-board shore power connection device further includes a locking assembly (not shown in the figure), and the locking assembly can lock or unlock the bracket 4 and the base 1. During the process of rotating the bracket 4, when the bracket 4 is rotated to a certain angle, the bracket 4 can be locked at this angle through the locking assembly. By rotating the bracket 4 to different angles, the outgoing cable direction after the cable extends from the bracket 4 can be adjusted, which is beneficial to improving the convenience of connecting the cable to the power supply system of the port. The distance between the cable extending from the bracket 4 and the hull can also be adjusted to ensure that the cable does not contact the hull, providing a better protection effect for the cable.

[0042] Optionally, the locking assembly includes a first locking portion and a plurality of second locking portions. The first locking portion is provided on the base 1, and the plurality of second locking portions are sequentially provided on the bracket 4 along the rotation direction of the bracket 4. The plurality of second locking portions can all be connected to or separated from the first locking portion. By connecting different second locking portions to the first locking portion, the rotation angle of the bracket 4 can be adjusted. It can be understood that the angle between two adjacent second locking portions is the minimum angle that the bracket 4 can adjust; the angle between two adjacent second locking portions is a known value, which can be determined based on experience or multiple repeated tests.

[0043] Specifically, the first locking portion is a locking pin, the locking pin is slidably provided on the base 1, and the plurality of second locking portions are locking holes opened on the bracket 4. By rotating the bracket 4, any one of the locking holes can be aligned with the locking pin, and by sliding the locking pin, the locking pin can be inserted into or pulled out of the corresponding locking hole, with a simple structure and easy operation.

[0044] Optionally, the bracket 4 includes a cable guiding structure for guiding the cable, and thus the cable can be guided through the cable guiding structure, which can improve the smoothness of the cable outgoing.

[0045] Optionally, the cable guiding structure includes a guiding roller 41 that can contact the cable, and the guiding roller 41 is rotatably provided on the bracket 4. It should be noted that when using shore power, the cable is transported from the hull to the dock, and the movement of the cable drives the guiding roller 41 to rotate, which has the effect of reducing the friction of the cable.

[0046] Optionally, as Figures 1-3As shown in the figure, the driving mechanism 3 includes a driving unit 31. The driving unit 31 includes a folding bracket 311 and a driving component 312. The folding bracket 311 is movably connected between the base 1 and the deck 100. The folding bracket 311 has a deployed state and a folded state. When the folding bracket 311 is in the deployed state, the height of the base 1 is higher than the dock of the port; when the folding bracket 311 is in the folded state, the base 1 lies on the deck 100; the driving component 312 is used to drive the folding bracket 311 to switch between the deployed state and the folded state. By supporting the folding bracket 311 between the base 1 and the deck 100 and driving the folding bracket 311 to switch between the deployed state and the folded state by the driving component 312, the purpose of lifting the base 1 can be achieved, and the stability and safety of the lifting of the base 1 can be improved.

[0047] Optionally, the deck 100 is provided with a groove 101. The bottom end of the folding bracket 311 is arranged in the groove 101, and the top end of the folding bracket 311 is connected to the base 1. Thus, when the folding bracket 311 is in the folded state, the height of the winch 2 can be reduced, which is beneficial to reducing the center of gravity of the hull and improving the stability of the hull.

[0048] Optionally, the folding bracket 311 includes a first support member 3111 and a second support member 3112. The first support member 3111 and the second support member 3112 are pivotally connected to form an X-shaped structure. The top end of the first support member 3111 is pivotally connected to the base 1, the bottom end of the first support member 3111 is slidably connected to the deck 100, the top end of the second support member 3112 is slidably connected to the base 1, and the bottom end of the second support member 3112 is pivotally connected to the deck 100; the driving component 312 is a linear driving component 312. The linear driving component 312 is rotatably arranged on the deck 100, and the driving end of the driving component 312 is pivotally connected to the top end of the first support member 3111. When the driving end of the linear driving component 312 extends, it can drive the top end of the first support member 3111 to rise, the bottom end of the first support member 3111 slides in the direction close to the bottom end of the second support member 3112, and the top end of the second support member 3112 slides in the direction close to the top end of the first support member 3111, thereby raising the base 1; when the driving end of the linear driving component 312 retracts, it can drive the top end of the first support member 3111 to descend, the bottom end of the first support member 3111 slides in the direction away from the bottom end of the second support member 3112, and the top end of the second support member 3112 slides in the direction away from the top end of the first support member 3111, thereby lowering the base 1. With the above arrangement of the folding bracket 311, it also has the advantages of simple structure, convenient layout and installation on the hull, and is beneficial to reducing costs.

[0049] Exemplarily, the first support member 3111 and the second support member 3112 are pivotally connected by a first pin shaft. The top end of the first support member 3111 is pivotally connected to the base 1 by a second pin shaft. The bottom end of the second support member 3112 is pivotally connected to the deck 100 by a third pin shaft.

[0050] In this embodiment, the linear drive assembly 312 includes a motor 3121, a hydraulic pump 3122, and a hydraulic cylinder 3123. The motor 3121 provides power for the hydraulic pump 3122, so that the hydraulic pump 3122 outputs pressure oil to the hydraulic cylinder 3123, and then the piston rod of the hydraulic cylinder 3123 (the above-mentioned driving end is one end of the piston rod) reciprocates. Of course, the linear drive assembly 312 can also adopt existing linear drivers such as electric push rods.

[0051] Specifically, as Figure 4 shown, there are two driving units 31. The two driving units 31 are symmetrically arranged with respect to a preset plane, and the first pin shafts of the two driving units 31 are fixedly connected to ensure the synchronization of the two driving units 31. The preset plane is perpendicular to the axial direction of the first pin shaft. With such a setting, the stability of the folding bracket 311 can be improved, and the lifting of the base 1 can be made smoother.

[0052] Furthermore, there are two hydraulic cylinders 3123, and there is one motor 3121 and one hydraulic pump 3122. Then, one hydraulic pump 3122 provides pressure oil for the two hydraulic cylinders 3123, which is beneficial to improving the synchronization of the two driving units 31.

[0053] Optionally, as Figures 1-3 shown, the bottom end of the first support member 3111 is in rolling connection with the deck 100; the top end of the second support member 3112 is in rolling connection with the deck 100, which can reduce the friction between the first support member 3111 and the base 1, and the friction between the second support member 3112 and the base 1, and improve the smoothness and stability of the lifting of the base 1.

[0054] Specifically, rollers 3113 are provided at the bottom end of the first support member 3111 and the top end of the second support member 3112. The deck 100 is provided with tracks 3114 corresponding to the rollers 3113 of the first support member 3111, and the base 1 is provided with tracks 3114 corresponding to the rollers 3113 of the second support member 3112. The rollers 3113 can roll along the corresponding tracks 3114.

[0055] This embodiment also provides a shipborne shore power equipment, which includes a shipborne power receiving system and the shipborne shore power connection device as described above. The shipborne power receiving system can be electrically connected to the power supply system of the port through a cable, and the cable is wound around the reel 2.

[0056] The on-board shore power equipment of this embodiment has the same beneficial effects as the above-mentioned on-board shore power connection device by applying the above-mentioned on-board shore power connection device, which will not be elaborated here.

[0057] Note that the above is only the preferred embodiment of the present invention and the technical principles applied. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described here, and various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments only.
