Description

Technical Field

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

[0002] A floating rapid battery replacement platform is a specially designed floating facility for efficiently and safely replacing and transporting battery packs in aquatic environments. Equipped with an automated conveying system, the platform precisely delivers spare batteries to designated locations and retrieves spent batteries, ensuring a fast and smooth replacement process. The platform typically incorporates safety features such as anti-collision fenders to adapt to complex aquatic operating environments and ensure safe and stable operations.

[0003] When replacing ship battery packs on the water, existing rapid replacement platforms usually rely on manual operation to pick up and place battery packs. This process 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 rapid replacement platform for ship battery packs. Summary of the Invention

[0005] In order to overcome the shortcomings of existing replacement platforms that rely on manual operation to pick up and place battery packs, such as being cumbersome, time-consuming, labor-intensive, and having potential safety risks, the present invention provides a ship battery pack rapid replacement platform.

[0006] A ship battery pack rapid replacement platform includes a floating base, which is fixedly connected to a replacement frame by bolts, and a floating anti-collision pad is fixedly connected to the replacement frame. The replacement frame is provided with a plurality of evenly distributed compartments, each of which contains a battery pack body. The replacement frame is equipped with symmetrically distributed motors, and the replacement frame is rotatably connected to symmetrically distributed cover plates. The output shaft of each motor is connected to an adjacent cover plate through a coupling. Each battery pack body is rotatably connected to a symmetrically distributed rotating frame. Symmetrically distributed first torsion springs are connected between the rotating frame and the adjacent battery pack body, and the symmetrically distributed first torsion springs are all wound around the adjacent rotating frame.

[0007] Furthermore, it also includes a fixing mechanism for clamping and positioning the battery pack body in each compartment. The fixing mechanism is arranged in the replacement rack. The fixing mechanism includes a guide frame. The evenly distributed guide frames are all slidably connected to the compartments of the replacement rack. Each guide frame is connected to the replacement rack with a symmetrically distributed first spring.

[0008] Furthermore, the inner side of each guide frame is provided with symmetrically distributed inclined surfaces, and the battery pack body and the adjacent guide frames are squeeze-fitted.

[0009] Furthermore, it also includes a guiding mechanism for accurately placing the old battery pack body into the replacement stand. The guiding mechanism is arranged on each guide frame. The guiding mechanism includes a connecting plate. The symmetrically distributed connecting plates are respectively fixed to each guide frame. Each connecting plate is rotatably connected to a guide plate. A symmetrically distributed second torsion spring is connected between the guide plate and the adjacent connecting plate. The symmetrically distributed second torsion springs are all wound around the adjacent guide plates.

[0010] Furthermore, the inner wall of the replacement stand is provided with symmetrically distributed guide grooves on a side close to the guide plate.

[0011] Furthermore, it also includes an anti-tilt mechanism for keeping the replacement stand balanced when loading and unloading the battery pack body. The anti-tilt mechanism is arranged on the middle guide plate. The anti-tilt mechanism includes a baffle. The symmetrically distributed baffles are respectively fixed to the middle guide plate. The symmetrically distributed baffles are all slidably connected to guide rods. Tension springs are connected between the guide rods and adjacent baffles, and each tension spring is wound around the adjacent guide rod.

[0012] Furthermore, 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. The anchoring mechanism includes an L-shaped pressure rod. Each cover plate is fixed with a symmetrically distributed L-shaped pressure rod. The replacement platform is slidably connected to a symmetrically distributed slide. Each slide is connected to the replacement platform with a symmetrically distributed second spring. The symmetrically distributed second springs are all wound around the adjacent slides. The slides along the longitudinal direction are all threadedly connected with a clamping frame, and the clamping frame passes through the outer wall of the replacement platform.

[0013] Furthermore, the threads at both ends of the bracket are arranged in opposite directions.

[0014] Furthermore, a plurality of slots are provided on the bottom plate of the replacement stand.

[0015] Furthermore, the L-shaped pressure rod is squeeze-fitted with the adjacent sliding bracket.

[0016] The present invention has the following advantages: the present invention drives the cover to flip outward and open by controlling the motor, and the turntable flips upward under the action of the first torsion spring to form a handle. The staff on the ship can easily lift the battery pack bodies one by one through the lifting device, which simplifies the process of taking and placing the battery pack bodies and improves work efficiency; during the lifting process, the inclined surface formed by the guide plate and the top of the replacement stand, and the trumpet shape formed by the guide plate and the compartment opening make it smoother when the goods are moved out of the compartment, avoiding the occurrence of jamming, and can also guide the goods to slide in or out of the compartment smoothly, further improving the taking and placing efficiency; during navigation, the guide frame can firmly fix the lower part of the battery pack body, preventing the battery pack body from shaking or colliding due to external factors such as waves, enhancing the stability of the battery pack body, and ensuring the safety of the battery pack body during transportation.

[0017] The present invention forms a trumpet mouth through the upward sliding guide rod and the guide plate of the side compartment, which further improves the speed of the battery pack body entering the compartment, and ensures through the blocking rod that even in the event of misoperation, the cargo can be taken and placed again through simple adjustment, thereby improving the flexibility and practicality of the entire device.

[0018] The present invention ensures that the platform and the ship can be firmly connected through the L-shaped pressure rod, the slide and the clamping frame, avoids the platform from drifting away due to waves, and improves the replacement efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 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 fixed with a replacement stand 2 by bolts, and a floating anti-collision pad 3 is fixed 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. The replacement stand 2 is rotatably connected to symmetrically distributed cover plates 5, and the output shaft of each motor 6 is connected to the adjacent cover plate 5 through a coupling. Each battery pack body 4 is rotatably connected to two front-to-back symmetrical rotating frames 7, and symmetrically distributed first torsion springs 8 are connected between the rotating frames 7 and the adjacent battery pack bodies 4, one of the rotating frames 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. 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 stand 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. Two connecting plates 11 are fixedly connected to the four guide frames 9 on both sides, and four connecting plates 11 are fixedly connected to the two guide frames 9 in the middle. The sixteen connecting plates 11 are rotatably connected to a guide plate 12. A symmetrically distributed second torsion spring 13 is connected between the guide plate 12 and the adjacent connecting plate 11. The symmetrically distributed second torsion spring 13 is wound around the adjacent guide plate 12. The inner wall of the replacement stand 2 is provided with symmetrically distributed guide grooves 131 on the side close to the guide plate 12. 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 rack 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 twisted. In order to prevent waves from hitting the battery pack body 4 and causing damage during navigation, the cover plate 5 is usually placed on the replacement rack 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. 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 1°, 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 bodies 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 upward under the elastic force of the first spring 10, thereby driving the connecting plate 11 and the guide plate 12 to move upward together. When the bottom of the upward 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. The guide plate 12 and the top of the replacement stand 2 form an inclined plane. In order to keep the platform balanced, it is generally taken from both sides first and then from the middle. When placing, it is placed in the middle first and then on both 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. Due to the fluctuation of the water surface, the platform may 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 trumpet 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 be placed 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 a folded state with one up and one down, and finally the platform can be controlled to move toward land. In summary, by controlling the motor 6 to drive the cover plate 5 to flip outward and open, and the rotating rack 7 to flip upward under the action of the first torsion spring 8 to form a handle, the staff on the ship can conveniently lift the battery pack bodies 4 one by one through the lifting device, which simplifies the process of taking and placing the battery pack bodies 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, make it smoother for the goods to be moved out of the compartment, 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 taking 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 colliding 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] Example 2: Based on Example 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 all slidably connected to a guide rod 15. A tension spring 16 is connected between the guide rod 15 and the adjacent baffle rod 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 simultaneously press on the guide rod 15, 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 set at an angle, 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 ship's lifting device lifts the battery pack body 4 in the middle due to misoperation, according to the previous steps, the guide plate 12 in the middle compartment will drive the baffle 14 and the guide rod 15 to flip outward, causing the baffle 14 to press on the battery pack bodies 4 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 removed 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 in and put away through simple adjustments, thereby improving the flexibility and practicality of the entire device.

[0044] like Figure 9 and Figure 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 away from each other are fixed with L-shaped pressure rods 17. The left and right sides of the replacement platform 2 are symmetrically connected with slides 18 in a front-to-back sliding manner. 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 longitudinal slides 18. The clamping frame 19 passes through the outer wall of the replacement platform 2, and the threads at both ends of the clamping frame 19 are arranged in opposite directions. A number of slots are provided on the bottom plate of the replacement platform 2, and the L-shaped pressure rod 17 is squeezed and fitted with the adjacent slides 18.

[0045] When the platform is moved to the side of the ship, in order to ensure that the platform and the ship are firmly connected and to avoid the platform drifting away due to waves, the specific operations are 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 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. The second spring 20 is compressed, thereby driving the bracket 19 to rotate outward until it presses 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. 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 principles of the present invention should be included in the scope of protection of the present invention.
