Description

Technical Field

[0001] This invention relates to the field of marine power system technology, specifically to a waterproof device for a marine battery box and a battery swapping vessel. Background Technology

[0002] The battery-swapping vessel integrates at least one waterproof battery box, adopts a standardized PACK battery swapping mode that combines ship, vehicle, and storage, and is equipped with a vehicle-grade high-power-density motor. The number of battery packs can be flexibly configured according to load requirements, making it suitable for scenarios such as inland waterway freight. When waterproof battery boxes protect batteries, they are typically placed inside perforated battery boxes on ships. To ensure battery cooling and waterproofing, several holes are usually made on the side wall of the battery box, with the holes angled downwards. During ship transport, ships may encounter wind, waves, and severe rocking. When the ship rocks, water from outside the ship can easily flow into the battery box through the holes due to wind. At the same time, a small amount of water may flow in the opposite direction inside the holes, affecting the waterproofing efficiency and overall waterproofing quality of the battery box. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a waterproof device for a ship battery box and a battery swapping vessel, including a battery box and a battery, wherein the side wall of the battery box has a vent hole, and further includes: A rotating mechanism is installed on the inner wall of the battery box and is used to rotate when the other components move. The motion mechanism is installed inside the rotating mechanism and is used to retract during the operation of the rotating mechanism.

[0004] Furthermore, the battery box includes: The moving component is installed on the inner wall of the battery box and is used to move the battery. The rotating component is installed on the inner wall of the battery box and is used to rotate under the influence of force.

[0005] Furthermore, the rotating mechanism includes: A sliding component is mounted on the outer surface of the rotating component and is used to move when the rotating component rotates. The swing assembly is installed on the inner wall of the battery box and is used to swing when the sliding assembly moves.

[0006] Furthermore, the sports apparatus includes: The push component is installed inside the swing component via a telescopic component and is used to move when the swing component swings. The telescopic component includes a spring fixedly connected inside the swing assembly, a telescopic block fixedly connected to the end of the spring away from the swing assembly, and a sealing strip fixedly connected to the side of the telescopic block closer to the sliding assembly.

[0007] Furthermore, the movable component includes several fixed blocks fixedly connected to the inner wall of the battery box, and a support frame is fixedly connected to the bottom of the fixed blocks; A movable plate is slidably connected to the bottom of the support frame, and a lifting frame is slidably connected inside the movable plate.

[0008] Furthermore, the rotating assembly includes two positioning blocks fixedly connected to the inner wall of the battery box, and a rotating rod is rotatably connected to the inner wall of the positioning blocks; Two rotating rods are fixedly connected to bevel gears at their ends that are close to each other, and a rotating torque is fixedly connected to the side wall of one of the bevel gears. The outer surfaces of the two bevel gears are meshed, and the rotational torque extends through the side wall of the battery box to the outside of the battery box.

[0009] Furthermore, the sliding assembly includes two elastic rods fixedly connected to the outer surface of the rotating rod, and a sliding strip is fixedly connected to the end of the two elastic rods away from the rotating rod; A connecting plate is rotatably connected to the side wall of the sliding bar near the rotating rod; The side wall of the sliding bar is slidably connected to the inner wall of the battery box.

[0010] Furthermore, the swing assembly includes a swing plate rotatably connected to the end of the connecting plate away from the rotating rod, and the side wall of the swing plate is provided with a sliding groove; A fixing bar is fixedly connected to the side of the swing plate near the connecting plate, and connecting rods are rotatably connected to the left and right sides of several fixing bars; The device includes several swing plates, and the side walls of the swing plates are rotatably connected to the inner wall of the battery box.

[0011] Furthermore, the actuating component includes a scraper fixedly connected to the side of the two telescopic blocks away from the sealing strip, and two limiting plates are fixedly connected to the side wall of the scraper; The end of the spring furthest from the telescopic block is fixedly connected to the inner wall of the sliding groove, while the side wall of the telescopic block is slidably connected to the inner wall of the battery box.

[0012] Furthermore, a battery-swapping vessel includes a hull fixedly connected to the bottom of a battery box, with a propeller rotatably connected to the right side of the hull.

[0013] The present invention has the following beneficial effects: 1. In this invention, after the swing plate is attached to the inner wall of the battery box, the vent hole is blocked. Blocking the vent hole prevents rainwater from leaking through the vent hole, reducing the possibility of rainwater being blown by the wind and entering the battery box through the vent hole during ship transportation. It also prevents water from flowing backward into the battery box through the hole, thus improving the overall quality of the battery box in waterproofing the internal components.

[0014] 2. In this invention, when the telescopic block slides, it drives the scraper to move. When the scraper moves, its sidewall contacts the sidewall of the swing plate, thereby scraping away the rainwater on the surface of the swing plate. This reduces the situation where some rainwater adheres to the sidewall of the swing plate during the process of the swing plate blocking and resetting the water, causing the swing plate to carry rainwater into the battery box. This keeps the sidewall of the swing plate clean and further improves the overall quality of the battery box in waterproofing the internal components.

[0015] 3. In this invention, while the swing plate adheres to the inner wall of the battery box to block rainwater, the sealing strip seals the gap between the swing plate and the battery box. After blocking the rainwater, the telescopic block pushes the sealing strip upward when it resets. As the sealing strip moves upward, the rainwater on the sealing side is scraped off by the side wall of the swing plate, reducing water seepage when the swing plate swings to seal the side wall of the battery box. This enhances the waterproof effect of the swing plate and improves the overall waterproof efficiency of the device.

[0016] 4. In this invention, when the scraper moves, its sidewall contacts the sidewall of the swing plate and scrapes off the water flow attached to the sidewall of the swing plate. When the scraper scrapes off the water flow, some of the water flow moves to both sides of the scraper. When these water flows to both sides, they are blocked by the limiting plate and flow out to the outside of the battery box through the ventilation hole. This reduces the situation where some water flows to both sides and enters the battery box under the push of the scraper when scraping off the water flow attached to the sidewall of the swing plate, and further improves the overall efficiency of the device in waterproofing.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 - Figure 11 As shown, the present invention is a waterproof device for a ship battery box and a battery swapping vessel, including a battery box 1 and a battery 4. The side wall of the battery box 1 has a vent hole, and it also includes: Rotating mechanism 2 is installed on the inner wall of battery box 1 and is used to rotate when the other components move; The motion mechanism 3 is installed inside the rotating mechanism 2 and is used to retract when the rotating mechanism 2 is running.

[0022] Battery box 1 includes: The moving component 11 is installed on the inner wall of the battery box 1 and is used to move the battery 4. Rotating component 12 is installed on the inner wall of battery box 1 and is used to rotate under the action of force.

[0023] Rotating mechanism 2 includes: The sliding component 21 is mounted on the outer surface of the rotating component 12 and is used to move when the rotating component 12 rotates; The swing assembly 22 is installed on the inner wall of the battery box 1 and is used to swing when the sliding assembly 21 moves.

[0024] Motion mechanism 3 includes: Push component 31 is installed inside the swing component 22 via a telescopic component and is used to move when the swing component 22 swings; The telescopic component includes a spring 311 fixedly connected inside the swing assembly 22. A telescopic block 312 is fixedly connected to the end of the spring 311 away from the swing assembly 22. A sealing strip 313 is fixedly connected to the side of the telescopic block 312 close to the sliding assembly 21.

[0025] The movable component 11 includes several fixing blocks 111 fixedly connected to the inner wall of the battery box 1, and a support frame 112 is fixedly connected to the bottom of the fixing blocks 111. A movable disk 113 is slidably connected to the bottom of the support frame 112. A lifting frame 114 is slidably connected inside the movable disk 113. The movable disk 113 will drive the lifting frame 114 to move at the bottom of the support frame 112. After the movable disk 113 moves to a position where it can dock with the battery 4, the lifting frame 114 moves inside the movable disk 113. When the lifting frame 114 moves, it will dock with the top of the battery 4.

[0026] The rotating assembly 12 includes two positioning blocks 121 fixedly connected to the inner wall of the battery box 1, and a rotating rod 122 is rotatably connected to the inner wall of the positioning blocks 121. Two rotating rods 122 are fixedly connected to bevel gears 123 at their close ends, and a rotating torque 124 is fixedly connected to the side wall of one of the bevel gears 123. The outer surfaces of the two bevel gears 123 are meshed together. The rotating torque 124 extends through the side wall of the battery box 1 to the outside of the battery box 1. When the rotating torque 124 rotates, it will drive the bevel gear 123 to rotate. When the bevel gear 123 rotates, it will drive the other bevel gear 123 connected to it to rotate. When the two bevel gears 123 rotate, they will respectively drive the rotating rod 122 connected to them to rotate inside the positioning block 121.

[0027] The sliding assembly 21 includes two elastic rods 211 fixedly connected to the outer surface of the rotating rod 122, and a sliding strip 212 is fixedly connected to one end of the two elastic rods 211 away from the rotating rod 122; A connecting plate 213 is rotatably connected to the side wall of the sliding bar 212 near the rotating rod 122; The side wall of the sliding bar 212 is slidably connected to the inner wall of the battery box 1. When the sliding bar 212 slides, it pushes the connecting plate 213 to move. When the connecting plate 213 moves, it pushes the swing plate 221 connected to it to swing on the inner wall of the battery box 1.

[0028] The swing assembly 22 includes a swing plate 221 rotatably connected to the end of the connecting plate 213 away from the rotating rod 122, and the side wall of the swing plate 221 is provided with a sliding groove 222. A fixing strip 223 is fixedly connected to the side of the swing plate 221 near the connecting plate 213, and a connecting rod 224 is rotatably connected to the left and right sides of several fixing strips 223; Several swing plates 221 are provided. The side wall of the swing plate 221 is rotatably connected to the inner wall of the battery box 1. When the swing plate 221 swings, it will drive the other swing plates 221 to swing through the fixing strip 223 and connecting rod 224 at its top, so that the side wall of the swing plate 221 is in contact with the inner wall of the battery box 1. After the swing plate 221 is in contact with the inner wall of the battery box 1, the vent will be blocked.

[0029] The pushing component 31 includes a scraper 314 fixedly connected to the side of the two telescopic blocks 312 away from the sealing strip 313, and two limiting plates 315 fixedly connected to the side wall of the scraper 314; The end of the spring 311 away from the telescopic block 312 is fixedly connected to the inner wall of the sliding groove 222. The side wall of the telescopic block 312 is slidably connected to the inner wall of the battery box 1. During the unfolding process, the swing plate 221 will pull the telescopic block 312 to slide upward on the side wall of the battery box 1. When the telescopic block 312 slides, it will drive the scraper 314 to move. When the scraper 314 moves, its side wall will contact the side wall of the swing plate 221 and thus scrape away the rainwater on the surface of the swing plate 221.

[0030] A battery swapping vessel includes a hull 101 fixedly connected to the bottom of a battery box 1. A propeller 102 is rotatably connected to the right side of the hull 101. When the hull 101 is started, a power unit located inside the hull 101 is activated. After the power unit is activated, it drives the propeller 102 to rotate. When the propeller 102 rotates, it propels the hull 101 to move in the river channel to begin transportation.

[0031] In operation, the power unit located inside the hull 101 is first activated. Once activated, the propeller 102 rotates, propelling the hull 101 along the river to begin transport. After the hull 101 completes transport and enters the port via the propeller 102, staff will open the entrance to the battery box 1. Once the entrance is open, staff will move the battery 4 to be replaced to the entrance. At this point, the moving plate 113, driven by its internal motor, moves at the bottom of the support frame 112. As the moving plate 113 moves, it drives its internal motor... The lifting frame 114 moves synchronously. After the moving plate 113 moves to a position where it can dock with the battery 4, the lifting frame 114 moves inside the moving plate 113. When the lifting frame 114 moves, it docks with the top of the battery 4. Then the moving plate 113 drives the battery 4 into the battery box 1 through the lifting frame 114, and then places the battery 4 at the connection point of the battery box 1. After the battery 4 is replaced, the entrance of the battery box 1 is closed to close the battery box 1. Then the battery box 1 is started. The power unit inside the battery box 1 drives the propeller 102 to move through the power inside the battery 4, thus completing a complete workflow.

[0032] During the transportation of the hull 101, occasional waves may be encountered. At this time, the operator will rotate the rotary knob 124. The rotation of the rotary knob 124 will drive the bevel gear 123 to rotate, which in turn drives another bevel gear 123 connected to it to rotate. The rotation of both bevel gears 123 will respectively drive the rotating rod 122 connected to it to rotate inside the positioning block 121. The rotation of the rotating rod 122 will cause the connected spring rod 211 to rotate. As the spring rod 211 rotates, it will surround the rotating rod 122 to form a ring. The rotation of the spring rod 211 will pull the connected sliding strip 212 downwards on the inner wall of the battery box 1. As the sliding strip 212 slides, it will push the connecting plate 213 to move. When the connecting plate 213 moves, it pushes the swing plate 221 connected to it to swing on the inner wall of the battery box 1. When the swing plate 221 swings, it drives the other swing plates 221 to swing through the fixing strip 223 and connecting rod 224 at its top, so that the side wall of the swing plate 221 is in contact with the inner wall of the battery box 1. After the swing plate 221 is in contact with the inner wall of the battery box 1, it will block the vent hole. After the vent hole is blocked, it will prevent rainwater from wind and waves from leaking through the vent hole. This reduces the situation where rainwater is blown by the wind and enters the battery box 1 through the vent hole when encountering wind and waves during the transportation of the hull 101. It also prevents water from flowing backward into the battery box 1 through the hole, thus improving the overall quality of the battery box 1 in waterproofing the internal components.

[0033] When the swing plate 221 swings on the inner wall of the battery box 1, the angle between it and the inner wall of the battery box 1 decreases. At this time, the spring 311 inside the sliding groove 222 is in a fully contracted state. During the swinging process of the swing plate 221, the spring 311 inside the sliding groove 222 will gradually reset under its own accumulated potential energy. During the reset process of the spring 311, it will push the telescopic block 312 connected to it to slide downward on the side wall of the battery box 1. The initial state of the telescopic block 312 is fully extended. During the sliding process of the telescopic block 312, as the angle between the swing plate 221 and the side wall of the battery box 1 decreases, it will retract. At the same time as the swing plate 221 slides, it will drive the scraper 314 to move through the scraper 314. After closing, the telescopic block 312 pushes the scraper 314 away from the side wall of the swing plate 221. Then, when the swing plate 221 is resetting to block rainwater, the swing plate 221 pulls the telescopic block 312 upward on the side wall of the battery box 1 during the unfolding process. When the telescopic block 312 slides, it drives the scraper 314 to move. When the scraper 314 moves, its side wall will contact the side wall of the swing plate 221, thereby scraping away the rainwater on the surface of the swing plate 221. This reduces the situation where some rainwater adheres to the side wall of the swing plate 221 during the process of the swing plate 221 blocking rainwater and resetting, causing the swing plate 221 to carry rainwater into the battery box 1. This keeps the side wall of the swing plate 221 clean and further improves the overall quality of the battery box 1 when waterproofing the internal components.

[0034] During the swinging motion of the swing plate 221 and its contact with the inner wall of the battery box 1, the spring 311 inside the sliding groove 222 pushes the telescopic block 312 to move when it resets. As the telescopic block 312 moves, it pulls the sealing strip 313 to move. As the sealing strip 313 moves, it gradually contacts the side wall of the sliding groove 222. While the swing plate 221 contacts the inner wall of the battery box 1 to block rainwater, the sealing strip 313 seals the gap between the swing plate 221 and the battery box 1. After blocking the rainwater, the telescopic block 312 pushes the sealing strip 313 upward when it resets. As the sealing strip 313 moves upward, the rainwater on the sealed side is scraped off by the obstruction of the side wall of the swing plate 221, reducing water leakage when the swing plate 221 seals the side wall of the battery box 1. This enhances the waterproof effect of the swing plate 221 and improves the overall waterproof efficiency of the device.

[0035] During the resetting swing of the swing plate 221, the angle between the swing plate 221 and the inner wall of the battery box 1 gradually increases. As the angle increases, the telescopic block 312 first stretches. When the telescopic block 312 reaches its limit, it slides upwards on the inner wall of the battery box 1 under the continued swing of the swing plate 221. During this sliding motion, the telescopic block 312 applies a pushing force to the spring 311, causing it to retract. Simultaneously, the movement of the telescopic block 312 pulls the scraper 314. As the scraper 314 moves... Its sidewall will contact the sidewall of the swing plate 221 and scrape off the water flow attached to the sidewall of the swing plate 221. When the scraper 314 scrapes off the water flow, some of the water flow will move to both sides of the scraper 314. When these water flows to both sides, they will be blocked by the limiting plate 315 and flow out to the outside of the battery box 1 through the ventilation hole. This reduces the situation where some water flows to both sides and enters the battery box 1 under the push of the scraper 314 when scraping off the water flow attached to the sidewall of the swing plate 221, and further improves the overall efficiency of the device in waterproofing.
