Description

Technical Field

[0001] The invention relates to the technical field of floating structures, and in particular to a rapid replacement platform for ship battery packs. Background Art

[0002] The floating ship battery rapid replacement platform is a specially designed floating facility for efficiently and safely replacing and transporting ship batteries in a water environment. The platform is equipped with an automated conveying system that can accurately transport spare batteries to designated locations and recycle exhausted batteries, ensuring that the entire replacement process is fast and smooth. The platform usually has safety designs such as anti-collision fenders to adapt to complex water operating environments and ensure the safety and stability of operations.

[0003] When replacing ship battery packs on the water, existing quick-change platforms usually rely on manual operation to pick up and place battery packs. This is not only cumbersome, time-consuming and labor-intensive, but also inefficient when batteries are frequently replaced. More importantly, the floating platform is shaky due to fluctuations on the water surface, which increases the difficulty of picking up and placing the battery packs and may even cause safety risks. This inconvenience and potential danger seriously affect the convenience and safety of battery replacement and limit the effectiveness of the platform in actual applications.

[0004] Based on the above situation, the present invention proposes a ship battery pack rapid replacement platform. Summary of the invention

DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Embodiment 1: A rapid replacement platform for ship battery packs, such as Figure 1-Figure 3 As shown, it includes a floating base 1, which is fixedly connected to a replacement stand 2 by bolts, and a floating anti-collision pad 3 is fixedly connected to the lower part of the replacement stand 2. Six evenly distributed compartments are opened in the replacement stand 2, and a battery pack body 4 is placed in each compartment. Two motors 6 are installed on the upper right side of the replacement stand 2, and symmetrically distributed cover plates 5 are rotatably connected to the replacement stand 2. The output shaft of each motor 6 is connected to the adjacent cover plate 5 through a coupling, and two front-to-back symmetrical rotating frames 7 are rotatably connected to each battery pack body 4. Symmetrically distributed first torsion springs 8 are connected between the rotating frames 7 and the adjacent battery pack bodies 4, and one rotating frame 7 is pressed on the other, and the symmetrically distributed first torsion springs 8 are all wound around the adjacent rotating frames 7.

[0032] like Figure 4 and Figure 5 As shown, it also includes a fixing mechanism for clamping and positioning the battery pack body 4 in each compartment, the fixing mechanism is arranged in the replacement rack 2, and the fixing mechanism includes a guide frame 9. The six guide frames 9 are all slidably connected to the compartments of the replacement rack 2. The six guide frames 9 and the replacement rack 2 are connected with symmetrically distributed first springs 10. The left and right inner walls of the six guide frames 9 are provided with inclined surfaces, and the battery pack body 4 and the adjacent guide frames 9 are squeezed together.

[0033] like Figure 6As shown, it also includes a guiding mechanism for accurately placing the old battery pack body 4 into the replacement rack 2, the guiding mechanism is arranged on each guide frame 9, the guiding mechanism includes a connecting plate 11, the number of the connecting plates 11 is sixteen, wherein the four guide frames 9 on both sides are fixedly connected to two connecting plates 11, and the two guide frames 9 in the middle are fixedly connected to four connecting plates 11, the sixteen connecting plates 11 are rotatably connected to the guide plates 12, symmetrically distributed second torsion springs 13 are connected between the guide plates 12 and the adjacent connecting plates 11, the symmetrically distributed second torsion springs 13 are all wound around the adjacent guide plates 12, and the inner wall of the replacement rack 2 is provided with symmetrically distributed guide grooves 131 on the side close to the guide plates 12, and the number of the guide grooves 131 is also sixteen.

[0034] Initially, the new battery pack body 4 has filled the compartment of the replacement stand 2. Under the action of the battery pack body 4's own gravity, the guide frame 9 is pressed against the battery pack body 4, and the guide plate 12 is supported by the inner wall of the compartment, so that the first spring 10 is in a compressed state and the second torsion spring 13 is in a twisted state. In order to prevent waves from hitting the battery pack body 4 and causing damage during navigation, the cover plate 5 is usually covered on the replacement stand 2 and pressed on the rotating frame 7, so the first torsion spring 8 is also in a twisted state.

[0035] First, transfer the device to the water surface. Under the action of the suspended base 1, the replacement platform will float on the water surface, and then control it to move to the side of the ship. Then control the motor 6 to drive the cover 5 to flip outward and open. Under the action of the first torsion spring 8, the rotating frame 7 will flip upward by about 8 degrees, and the two adjacent rotating frames 7 will be close together to form a handle. In this way, the staff on the ship can lift the battery pack body 4 one by one through the lifting device.

[0036] During the lifting process, when the battery pack body 4 is moved out of the compartment of the replacement stand 2, the guide frame 9 will automatically bounce up under the elastic force of the first spring 10, thereby driving the connecting plate 11 and the guide plate 12 to move up together. When the bottom of the upwardly moved guide plate 12 is flush with the guide groove 131, under the action of the second torsion spring 13, the guide plate 12 will flip outward into the guide groove 131, and the guide plate 12 and the top of the replacement stand 2 form an inclined surface. In order to keep the platform balanced, it is generally taken from both sides first and then from the middle. When putting, put the middle first and then the two sides. This can ensure the stability of the platform during the taking and placing process. Repeat the above steps until all the remaining battery pack bodies 4 are taken out.

[0037] Similarly, the battery pack body 4 replaced on the ship also needs to be transported back to land through this platform. The specific operation is as follows: the staff can slowly place the battery pack body 4 into the replacement stand 2 by pulling the rope. The fluctuation of the water surface may cause the platform to shake, and the suspended battery pack body 4 is not easy to align with the compartment, so that the lowered battery pack body 4 will be pressed on the flipped guide plate 12. Since the guide plate 12 and the opening of the compartment form a horn shape, the battery pack body 4 can be guided to slide smoothly into the compartment. As the battery pack body 4 continues to move downward and press on the guide frame 9, the guide frame 9 will drive the connecting plate 11 and the guide plate 12 to move downward. At the same time, the inner wall of the replacement stand 2 will press against the guide plate 12 to straighten it, and allow the first spring 10 to be compressed again and the second torsion spring 13 to be twisted. In addition, the symmetrically distributed inclined surfaces on the inner wall of the guide frame 9 can adjust the position of the battery pack body 4 to place it in the center.

[0038] When the replacement rack 2 is full, the motor 6 can be controlled to drive the cover plate 5 to flip down and close, and the adjacent rotating rack 7 can be pressed into an up-and-down folded state, and finally the platform can be controlled to sail to the land. In summary, by controlling the motor 6 to drive the cover plate 5 to flip outward and open, and the rotating rack 7 flips upward to form a handle under the action of the first torsion spring 8, the staff on the ship can conveniently lift the battery pack body 4 one by one through the lifting device, which simplifies the process of taking and placing the battery pack body 4 and improves work efficiency.

[0039] During the lifting process, the inclined surface formed by the guide plate 12 and the top of the replacement stand 2, as well as the trumpet shape formed by the guide plate 12 and the compartment opening, allow the goods to be moved out of the compartment more smoothly, avoiding the occurrence of jamming, and can also guide the goods to slide in or out of the compartment smoothly, further improving the efficiency of picking and placing; during navigation, the guide frame 9 can firmly fix the lower part of the battery pack body 4, preventing the battery pack body 4 from shaking or impacting due to external factors such as waves, thereby enhancing the stability of the battery pack body 4 and ensuring the safety of the battery pack body 4 during transportation.

[0040] Embodiment 2: Based on embodiment 1, Figure 7 and Figure 8 As shown, it also includes an anti-tilt mechanism for keeping the replacement stand 2 balanced when loading and unloading the battery pack body 4. The anti-tilt mechanism is arranged on the middle guide plate 12. The anti-tilt mechanism includes a baffle 14. Eight baffles 14 are respectively fixed to the middle guide plate 12. The eight baffles 14 are slidably connected to guide rods 15. Tension springs 16 are connected between the guide rods 15 and the adjacent baffle rods 14. Each tension spring 16 is wound around the adjacent guide rod 15.

[0041] When the cover 5 is placed on the replacement stand 2, it will press on the guide rod 15 at the same time, causing the guide rod 15 to slide downward and stretch the tension spring 16. When the cover 5 is flipped outward to open, the guide rod 15 slides upward under the elastic force of the tension spring 16. Since the guide rod 15 is inclined, the upward sliding guide rod 15 forms a trumpet mouth with the guide plate 12 of the side compartment. When the battery pack body 4 is placed in the compartments on both sides, the guide rod 15 and the guide plate 12 work together to further increase the speed at which the battery pack body 4 enters the compartment.

[0042] However, in actual operation, when the lifting device of the ship lifts the battery pack body 4 located in the middle due to misoperation, according to the previous steps, the guide plate 12 in the middle compartment will drive the blocking rod 14 and the guide rod 15 to flip outward, causing the blocking rod 14 to press on the battery pack bodies 4 located on both sides. At this time, if you continue to try to lift the battery pack bodies 4 on both sides, the battery pack bodies 4 on both sides will not be able to be taken out due to the pressing effect of the guide rod 15.

[0043] In this situation, the middle compartment should be filled with the replaced battery pack body 4 first, so that the guide plate 12 will drive the guide rod 15 to flip back to the initial state, thereby unlocking the locked battery pack bodies 4 on both sides. In summary, the barrier rod 14 ensures that even in the event of misoperation, the cargo can be taken and placed through simple adjustments, thereby improving the flexibility and practicality of the entire device.

[0044] like Fig. 9 and Fig.10 As shown, it also includes an anchoring mechanism for making the replacement platform and the ship relatively stable. The anchoring mechanism is arranged on the replacement platform 2, and the anchoring mechanism includes an L-shaped pressure rod 17. The left and right parts of the cover plate 5 that are away from each other are fixedly connected with the L-shaped pressure rod 17. The left and right sides of the replacement platform 2 are symmetrically slidably connected with slides 18 front and back. Two second springs 20 are connected between the four slides 18 and the replacement platform 2. Each second spring 20 is wound around the adjacent slide 18. A clamping frame 19 is threadedly connected between the slides 18 along the longitudinal direction. The clamping frame 19 passes through the outer wall of the replacement platform 2. The threads at both ends of the clamping frame 19 are arranged in opposite directions. A plurality of clamping grooves are opened on the bottom plate of the replacement platform 2. The L-shaped pressure rod 17 and the adjacent slide 18 are squeezed and matched.

[0045] When the platform moves to the side of the ship, in order to ensure that the platform and the ship are firmly connected and avoid the platform drifting away due to waves, the specific operation is as follows: first take two anchor ropes from the ship, tie one end of the anchor rope firmly to the ship, and throw the other end to the left and right sides of the platform. The anchor ropes will be scattered on the table surfaces on the left and right sides of the replacement stand 2. When the cover plate 5 is rotated outward to open, it will drive the L-shaped pressure rod 17 to rotate downward 90°, and then squeeze the slide 18 to move it inward, and the second spring 20 is compressed, thereby driving the bracket 19 to rotate outward until it is pressed on the anchor rope, thereby fixing the other end of the anchor rope.

[0046] In this way, even if encountering external factors such as waves, the platform can maintain a stable connection with the ship through the anchor rope, effectively avoiding the occurrence of drifting away. On the contrary, when the platform sails away, the cover plate 5 will rotate inward and close, and the L-shaped pressure rod 17 will rotate upward 90° to reset, and under the elastic force of the second spring 20, the slide 18 moves outward, thereby driving the bracket 19 to flip upward and reset. At this time, the staff will retract the anchor rope from the ship to release the connection between the platform and the ship.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
