Description

Technical Field

[0001] This invention relates to the field of ship charging pile technology, and in particular to a shore power charging pile for ships docking. Background Technology

[0002] To meet economic and environmental needs, more and more ships are using electricity as their propulsion energy. In order to charge ships, existing technologies use high-voltage shore power systems as dock power supply devices to transmit shore power to the ship.

[0003] Existing shore power charging stations place cables along the shore. Since the charging ports of ships are still far from the charging stations after docking, and the charging cables are also quite long, crew members need to go ashore to pull the cables to the ship and carry the charging heads onto the ship to connect them to the ship's charging ports before charging can begin. The heavy cables are difficult to move, making the charging operation difficult. Moreover, during the handling process, the cables repeatedly rub against the shore surface, causing wear and tear. Summary of the Invention

[0004] Purpose of the invention: The purpose of this invention is to provide a shore power charging station for ships docking, in order to overcome the above-mentioned shortcomings of the prior art.

[0005] Technical solution: A shore power charging pile for ships docking includes a distribution box, a shore platform, a flexible floating tube, a movable base, and a power supply cable. The power supply cable is electrically connected to the distribution box. The power supply cable is installed inside the flexible floating tube and extends along the flexible floating tube to the movable base. There is a gap between the bottom of the shore platform and the water surface, so that the flexible floating tube can float on the water surface and be buried below the shore platform.

[0006] The movable base is installed at the end of the flexible float tube away from the distribution box. The movable base floats on the water surface and extends upward. The upper end of the movable base is open to allow the charging head of the power supply cable to be removed.

[0007] As a further description of the above technical solution: the soft floating pipe is made of lightweight, soft, waterproof material and is hollow inside. Multiple upper concave rails are opened parallel to each other on the bottom surface of the offshore platform. Each upper concave rail is equipped with a coiled guide rod that is controlled to move by a distribution box. The bottom end of the coiled guide rod extends vertically downward and is inserted into the water. The soft floating pipe is staggered around each coiled guide rod.

[0008] As a further description of the above technical solution: the movable seat includes an upper edge portion and a docking portion that are interconnected to form an L-shape, and the upper part of the upper edge portion is sealed by a sealing cover.

[0009] As a further description of the above technical solution: three support frames are installed on the outer peripheral wall of the upper edge, and a pontoon is installed at the bottom of each support frame.

[0010] As a further description of the above technical solution: a lifting plate is installed inside the upper edge near the sealing cover. The lifting plate has a channel that allows the power supply cable to pass through. The diameter of the plug of the power supply cable that connects to the ship's charging port is larger than the channel of the lifting plate.

[0011] As a further description of the above technical solution: the upper edge has a spiral guide groove inside. The power supply cable that enters the upper edge from the docking part extends out from the upper edge after being guided and coiled by the spiral guide groove. A push-pull clamp is installed in the docking part. The push-pull clamp consists of two pairs of clamping wheels that clamp the power supply cable set in the docking part. The two clamping wheels are driven to rotate by a motor powered by the power distribution box.

[0012] As a further description of the above technical solution: the bottom of the docking part has a waterproof motor powered by a distribution box, the waterproof motor is submerged in water and can drive the propeller to rotate.

[0013] As a further description of the above technical solution: the offshore platform is equipped with a recovery unit driven by a power distribution box, and the movable base is connected to the rotating shaft of the recovery unit through a recovery rope.

[0014] Beneficial effects:

[0015] 1. The present invention sets the power supply cable inside a soft floating tube and a movable seat that float on the water. During charging, the soft floating tube and the movable seat can move and extend to approach the ship. The crew can obtain the power supply cable and connect it to the ship's charging port on the ship. There is no need to go ashore to pull the heavy power supply cable, which greatly reduces the difficulty of the charging operation.

[0016] 2. The power supply cable of this invention can change its length by bending and straightening inside the flexible floating tube. The power supply cable only needs to be pulled when the crew pulls it out of the moving seat. Compared with the existing charging method that requires dragging the power supply cable from the shore onto the ship, the dragging length of the power supply cable is greatly reduced. This reduces the difficulty of handling by the crew and also reduces the wear rate of the power supply cable. At the same time, the smooth inner wall of the flexible floating tube can further reduce the surface wear of the power supply cable. Attached Figure Description

[0023] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figures 1-4 A shore power charging pile for ships docking includes a distribution box 1, an offshore platform 2, a flexible floating tube 3, a movable base 4, and a power supply cable 5. The power supply cable 5 is electrically connected to the distribution box 1. The offshore platform 2 has a gap between its lower part and the water surface so that the flexible floating tube 3 can float on the water surface and be buried under the offshore platform 2. The movable base 4 is installed at the end of the flexible floating tube 3 away from the distribution box 1.

[0025] One end of the flexible float tube 3 is installed on the end face of the offshore platform 2 near the power distribution box 1, and the other end is connected to the movable base 4. The flexible float tube 3 is made of lightweight, soft, waterproof material and is hollow inside. The power supply cable 5 is placed inside the flexible float tube 3 and inserted into the movable base 4 along the flexible float tube 3. The power supply cable 5 inserted into the flexible float tube 3 can float on the water surface under the support of the flexible float tube 3 and bend together with the flexible float tube 3.

[0026] The bottom surface of the offshore platform 2 is provided with multiple concave rails 201. At least one screw motor 21 is installed in each concave rail 201. The screw motor 21 is powered by the power distribution box 1. The screw motor 21 can drive the threaded rod 22 installed in the concave rail 201 to rotate axially. The concave rail 201 is also provided with a coiled guide rod 23 that is threadedly engaged with the threaded rod 22. The top end of the coiled guide rod 23 is in contact with the horizontal top surface of the concave rail 201, and the bottom end of the coiled guide rod 23 extends vertically downward and is inserted into the water. The soft float tube 3 is alternately wound around each coiled guide rod 23.

[0027] When the ship is not being charged, the power distribution box 1 controls the screw motor 21 to drive the threaded rod 22 to rotate so that the adjacent coiled guide rods 23 are far apart from each other. The travel of the flexible float tube 3 around the coiled guide rods 23 increases, allowing it to be coiled and installed under the offshore platform 2, which is much shorter than the flexible float tube 3. When the ship is being charged, the power distribution box 1 controls the screw motor 21 to drive the threaded rod 22 to rotate so that the adjacent coiled guide rods 23 are close to each other. The travel of the flexible float tube 3 around the coiled guide rods 23 decreases, allowing it to extend a greater distance from the offshore platform 2. This allows the movable seat 4 installed at the end of the flexible float tube 3 to approach the ship that needs to be charged.

[0028] The movable seat 4 includes an upper edge 41 and a docking part 42 that are interconnected to form an L-shape. The power supply cable 5, which extends from the soft float tube 3 into the docking part 42, can be moved upward out of the movable seat 4 by being guided by the upper edge 41, so that the crew can access it and dock it with the ship's charging port. The upper part of the upper edge 41 is sealed by a sealing cover 43. After the movable seat 4 moves to the vicinity of the ship, the crew can open the sealing cover 43 to take out the power supply cable 5.

[0029] The length of the power supply cable 5 within the upper edge 41 is much greater than the length of the upper edge 41 itself, so that the crew can pull out a sufficiently long power supply cable 5 from the upper edge 41 to connect with the ship's charging port. Preferably, a lifting plate 44 is installed within the upper edge 41 near the sealing cover 43. The lifting plate 44 has a channel that is just large enough for the power supply cable 5 to pass through. The diameter of the plug of the power supply cable 5 that connects with the ship's charging port is larger than the channel of the lifting plate 44, so that the plug of the power supply cable 5 can be held by the lifting plate 44 near the upper end outlet of the upper edge 41.

[0030] Preferably, the upper edge 41 has a spiral guide groove 401 inside. The power supply cable 5 that enters the upper edge 41 from the docking part 42 extends out from the upper edge 41 after being guided and coiled by the spiral guide groove 401, so as to avoid the power supply cable 5 from accumulating and getting tangled in the upper edge 41, so that the crew can pull out the power supply cable 5 smoothly.

[0031] Preferably, a push-pull clamp 45 is installed inside the docking part 42. The push-pull clamp 45 consists of two pairs of clamping wheels that clamp the power supply cable 5 located inside the docking part 42. The two clamping wheels are driven by a motor powered by the power distribution box 1. When the crew pulls the power supply cable 5 out of the movable seat 4, the push-pull clamp 45 can continuously push the power supply cable 5 to the upper edge 41 to reduce the burden on the crew when pulling up the power supply cable 5. After the ship is charged, the push-pull clamp 45 can continuously pull the power supply cable 5 back to the upper edge 41, eliminating the need for the crew to move the power supply cable 5 back to the movable seat 4.

[0032] Three support frames 46 are installed on the outer periphery of the upper edge 41. Each support frame 46 has a pontoon box 47 installed at its bottom. The three support frames 46 are symmetrically installed on the outside of the upper edge 41 and are supported by the pontoon box 47 floating on the water surface to keep the upper edge 41 facing upward. The bottom of the docking part 42 has a waterproof motor 6 powered by the power distribution box 1. The waterproof motor 6 is submerged in the water and can drive the propeller 7 to rotate, thereby pushing the moving seat 4 to move on the water surface and approach the ship.

[0033] The offshore platform 2 has a recycling trough 202 into which the upper edge 41 moves. When not charging, the upper edge 41 moves into the recycling trough 202 and is limited by the side wall of the recycling trough 202, so it can only move away from the power distribution box 1. When charging is required, the waterproof motor 6 drives the propeller 7 to rotate and push the mobile seat 4 away from the offshore platform 2 and towards the ship, so that the crew can take out the power supply cable 5 in the mobile seat 4 and connect it to the ship's charging port for charging.

[0034] The offshore platform 2 is equipped with a recovery unit 8 powered by a power distribution box 1. The movable seat 4 is connected to the rotating shaft of the recovery unit 8 via a recovery rope 9. After charging is completed, the crew puts the power cable 5 back into the movable seat 4, and the recovery unit 8 can start and rotate the rotating shaft to pull the recovery rope 9, thereby pulling the movable seat 4 back into the recovery tank 202 for storage.

[0035] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
