Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a charging system and charging method for a ship's electric energy storage hatch cover. Background Technology

[0002] Hatch covers are an important component of ships, primarily functioning to seal and protect cargo, ensuring its safety during transport. Hatch covers have a hollow structure, allowing for the integration of battery modules to provide auxiliary power to the hull. For detachable hatch covers, after the container ship docks, the hatch covers need to be removed from the ship and stacked on the dock. However, when hatch covers are stacked together, the top hatch is too tall, making it inconvenient to charge its internal battery modules. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a charging system and charging method for ship electric energy storage hatch covers. Several hatch covers stacked together are connected in parallel through electrical connectors for charging, so as to solve the problem that hatch covers are not easy to charge due to excessive stacking height.

[0004] Technical Solution: To achieve the above objectives, the present invention provides a charging system for a ship's electric energy storage hatch cover, comprising a hatch cover and a charging station; the hatch cover has a built-in battery module, and an electrical connector is provided on one side of the hatch cover for charging and discharging the battery module; several hatch covers are stacked on the charging station, and several electrical connectors are sequentially connected to form an assembled main connector, and the stacked hatch covers are connected in parallel on the assembled main connector; the charging station has a charging output interface, and the bottom end of the assembled main connector is a charging end, which is electrically connected to the charging output interface.

[0005] Furthermore, the electrical connector has a first interface at its bottom and a second interface at its top; a plurality of electrical connectors are connected sequentially through the mating and cooperation of the first interface and the second interface.

[0006] Furthermore, the electrical connector is provided with a telescopic mechanism, the extension of which can move the first interface down to connect with the second interface.

[0007] Furthermore, the electrical connectors on each hatch cover are installed in the same position; when the edges of two adjacent hatch covers are flush, the first interface and the second interface on the two adjacent hatch covers are opposite each other.

[0008] Furthermore, a guide cone hole is provided above the second interface.

[0009] Further, the several hatches are stacked on the charging station with the same height, and the mounting height of each electrical connector on each hatch is the same; the telescopic stroke measuring mechanism is further arranged in the electrical connector, and the telescopic stroke measuring mechanism corresponds to measure the stretching degree of the telescopic mechanism; when the telescopic mechanism stretches to the butt joint of the first interface and the second interface, the measurement value of the corresponding telescopic stroke measuring mechanism is fixed.

[0010] Further, the second interface has several blocking pieces with different orientations, and the blocking height of each blocking piece is different; when the first interface is staggered with the second interface and is lowered to abut against the blocking piece, the measurement value of the telescopic stroke measuring mechanism is related to the blocking height of the blocking piece and the orientation.

[0011] Further, the hatch is provided with an alarm mechanism, and the alarm mechanism is signal connected with the telescopic stroke measuring mechanism.

[0012] Further, a charging method of a charging system of a ship electric energy storage hatch cover, comprising the following steps: S1: moving the hatch cover to the charging station; S2: stacking the subsequent hatch cover on the original hatch cover on the charging station; S3: the telescopic mechanism on the subsequent hatch cover drives the first interface to lower, and the second interface on the original hatch cover is butt jointed; S4: repeating S2 and S3 until the hatch cover is stacked to the specified number; at this time, the electrical connectors on each hatch cover are connected in sequence as an assembled total connector, and the stacked several hatch covers are connected in parallel on the assembled total connector; S5: the charging end at the bottom of the assembled total connector is electrically connected with the charging output interface on the charging station; based on the number of stacked hatch covers, the charging output interface outputs appropriate current and voltage to charge the several hatch covers connected in parallel.

[0013] Further, on the two adjacent stacked hatch covers, when the telescopic mechanism stretches to the butt joint of the first interface and the second interface, the measurement value of the corresponding telescopic stroke measuring mechanism is L; in S2, during the process of the first interface lowering with the telescopic mechanism, whether the first interface and the second interface are butt jointed is judged based on the maximum measurement value of the telescopic stroke measuring mechanism; if the maximum measurement value is L, it means that the first interface and the second interface are butt jointed; if the maximum measurement value is not L, it means that the first interface and the second interface are staggered, and then the orientation of the blocking piece abutted by the first interface is judged according to the actual maximum measurement value of the telescopic stroke measuring mechanism; then the telescopic mechanism is retracted, and the position of the hatch cover is adjusted according to the orientation information of the blocking piece abutted by the first interface, and then the telescopic mechanism drives the first interface and the second interface to butt joint again.

[0014] Beneficial effects: The present invention provides a charging system and charging method for ship electric energy storage hatch covers. Several hatch covers have electrical connectors, which are sequentially connected to form an assembled main connector. Several stacked hatch covers are connected in parallel on the assembled main connector. There is a charging output interface at the charging station, and the bottom end of the assembled main connector is the charging end. The charging end is very low, which facilitates direct electrical connection between the charging end and the charging output interface, thereby solving the problem that it is inconvenient to charge hatch covers stacked on top.

[0016] Appendix Fig. 2 A schematic diagram showing the hatch covers stacked at the charging station;

[0017] Appendix Fig. 3 This is a schematic diagram of a blocking element on an electrical connector. Detailed Implementation

[0018] The invention will now be further described with reference to the accompanying drawings.

[0019] As attached Figs. 1 to 3 The aforementioned charging system for a ship's electric energy storage hatch cover includes a hatch cover 2 and a charging station 8. The hatch cover 2 has a hollow structure with an internal cavity. A battery module is built into the hatch cover 2. When the hatch cover 2 is placed on the cargo hatch of a container ship 1, the battery module inside the hatch cover 2 can provide auxiliary power to the container ship 1. Because the hatch cover 2 needs to support the containers, it has high requirements for structural strength and mechanical performance. Therefore, the weight of the battery module inside the hatch cover 2 should be within a reasonable range. Thus, the battery module inside the hatch cover 2 is only suitable as an auxiliary power source for the container ship 1, and not as its main power source.

[0020] An electrical connector 3 is provided on one side of the hatch cover 2. The electrical connector 3 is used for charging and discharging the battery module. (See attached image) Fig. 1 In one embodiment shown, a power supply interface 7, opposite to the electrical connector 3, can be installed on the deck of the container ship 1. When the electrical connector 3 is connected to the power supply interface 7, the battery module inside the hatch cover 2 provides auxiliary power to the container ship 1. In practical applications, the electrical connector 3 and the power supply interface 7 must be properly sealed and waterproofed to prevent waves and wind and rain from affecting the power supply.

[0021] Hatch covers 2 can be of various types, including lift-off type, side-sliding type, and folding type. The hatch cover 2 in this invention is a lift-off type. After the container ship 1 docks, all containers must be unloaded. At the same time, the hatch cover 2 must be moved away from the ship. First, the containers above the hatch cover 2 are unloaded. After unloading, the hatch cover 2 is lifted away. Then, the containers in the cargo hold below the hatch cover 2 are unloaded. After the containers in the cargo hold are unloaded, new containers are loaded. After the new containers are loaded, the hatch cover 2 is closed. Then, new containers are stacked on the hatch cover 2.

[0022] For detachable hatch covers 2, regardless of whether they contain battery modules, they must be loaded and unloaded onto the dock for stacking. Since the hatch covers 2 in this invention contain battery modules, several hatch covers 2 will be stacked at the charging station 8 on the dock. During container loading and unloading, the battery modules inside the hatch covers 2 are charged. However, in practical applications, when the hatch covers 2 are stacked together, the height of the topmost hatch cover 2 can reach several meters, making it difficult for humans to reach. Traditional charging methods are inconvenient for charging the battery modules inside the hatch covers 2.

[0023] As attached Fig. 2 As shown in the diagram, in this invention, several hatch covers 2 are stacked on a charging station 8, and several electrical connectors 3 are sequentially connected to form an assembled main connector 11. The stacked hatch covers 2 are connected in parallel on the assembled main connector 11. A charging output interface 9 is located on the charging station 8, and the bottom end of the assembled main connector 11 is the charging end. The charging end is very low, facilitating direct electrical connection between the charging end and the charging output interface 9. This solves the problem that the hatch covers 2 stacked on top are too high, making it inconvenient to charge the battery modules inside.

[0024] A first interface 6 is provided at the bottom of the electrical connector 3, and a second interface 5 is provided at the top of the electrical connector 3. The first interface 6 and the second interface 5 are male and female to each other and can be connected to each other. Several electrical connectors 3 are connected in sequence through the mating and cooperation of the first interface 6 and the second interface 5, thereby forming an assembled general connector 11. When the hatch cover 2 is placed on the cargo hatch of the container ship 1, the first interface 6 can be covered by the sealing cover to prevent the impact of waves and wind and rain.

[0025] A telescopic mechanism 4 is provided on the electrical connector 3. In one embodiment, the telescopic mechanism 4 is an electric push rod. The battery module inside the hatch cover 2 supplies power to the telescopic mechanism 4, enabling the telescopic mechanism 4 to actively telescopically extend and retract. The first interface 6 is installed at the lower end of the telescopic mechanism 4. The extension movement of the telescopic mechanism 4 can drive the first interface 6 to move down to dock with the second interface 5.

[0026] The electrical connectors 3 on each hatch cover 2 are installed in the same position. When the edges of two adjacent hatch covers 2 are aligned, the first interface 6 and the second interface 5 on the two adjacent hatch covers 2 are also vertically opposite each other. Therefore, the alignment of the hatch covers 2 can be used to determine whether the first interface 6 and the second interface 5 are opposite each other. A guide cone hole is provided above the second interface 5 to guide the first interface 6 to be inserted into the second interface 5 along the guide cone hole.

[0027] Several hatch covers 2 are stacked at the same height on charging station 8, and the electrical connectors 3 are installed at the same height on each hatch cover 2. In practical applications, when the hatch cover 2 is installed on the cargo hatch of the container ship 1, the top of the outer facade of the hatch cover 2 will extend beyond the hatch coaming and be exposed. Correspondingly, the installation position of the electrical connector 3 is also close to the top of the outer facade of the hatch, so that the electrical connector 3 can also be exposed when the hatch cover 2 is installed on the cargo hatch.

[0028] An extension stroke measuring mechanism is also provided inside the electrical connector 3, which measures the extension degree of the extension mechanism 4. In practical applications, the extension stroke measuring mechanism can be a displacement sensor.

[0029] Since all hatch covers 2 are at the same height, and the electrical connectors 3 are installed at the same height on the hatch covers 2, the extension length of the telescopic mechanism 4 is fixed when the first interface 6 and the second interface 5 are precisely aligned. Therefore, the measurement value of the corresponding telescopic stroke measuring mechanism is also fixed. Thus, during the downward movement of the first interface 6 driven by the telescopic mechanism 4, the maximum measurement value of the telescopic stroke measuring mechanism can be used to determine whether the first interface 6 has successfully aligned with the second interface 5. If alignment is not successful, the position of the hatch covers 2 needs to be adjusted for re-alignment.

[0030] Several blocking elements with varying orientations and heights are located around the second interface 5. The blocking height refers to the height of the top of the blocking element. When the first interface 6 moves downwards toward a blocking element, the top of the blocking element can block the first interface 6. When the first interface 6 is offset from the second interface 5 and moves downwards to abut against a blocking element as the telescopic mechanism 4 extends, the measurement value of the telescopic stroke measuring mechanism will differ depending on the different blocking heights of the blocking elements. Furthermore, because the blocking elements are located in different orientations on the second interface 5, the measurement value of the telescopic stroke measuring mechanism is related to both the blocking height and the orientation of the blocking element when the first interface 6 abuts against it. Based on the maximum measurement value of the telescopic stroke measuring mechanism, it is possible to determine which blocking element the first interface 6 abuts against, and thus determine the orientation of the first interface 6 within the second interface 5. This orientation information can then be used to adjust the position of the hatch cover 2, improving the accuracy of the position adjustment.

[0031] As attached Fig. 3 In one embodiment shown, a blocking disk 10 is provided outside the second interface 5. Multiple stepped blocks are distributed circumferentially on the blocking disk 10. Each stepped block is a blocking component. The height of each stepped block is different, and the height of the stepped block is also different from the height of the second interface 5.

[0032] An alarm mechanism is also installed inside the hatch cover 2, and the alarm mechanism is signal-connected to the telescopic stroke measuring mechanism. During the downward movement of the first interface 6 driven by the telescopic mechanism 4, the maximum measurement value of the telescopic stroke measuring mechanism is used to determine whether the first interface 6 and the second interface 5 have successfully docked. If docking fails, the alarm mechanism sounds an alarm, reminding personnel to adjust the position of the hatch cover 2. If docking fails and the first interface 6 is still against a blocking component, the alarm mechanism can also issue different alarm signals based on the maximum measurement value of the telescopic stroke measuring mechanism, thus reminding personnel to adjust the position of the hatch cover 2 in which direction. The alarm mechanism can also be connected to a display screen, directly issuing alarm signals and displaying the positional information of the first interface 6 and the second interface 5 on the screen.

[0033] The present invention also provides a charging method for a charging system of a ship's electric energy storage hatch cover, comprising the following steps.

[0034] S1: The hatch cover 2 is moved from the container ship 1 to the charging station 8 by a crane.

[0035] S2: The subsequent hatch cover 2 is lifted by a crane and stacked on the original hatch cover 2 of the charging station 8, so that the edge of the subsequent hatch cover 2 is flush with the edge of the original hatch cover 2, and the first interface 6 on the subsequent hatch cover 2 is opposite to the second interface 5 on the original hatch cover 2.

[0036] S3: The telescopic mechanism 4 on the subsequent hatch cover 2 drives the first interface 6 to move down, so that the first interface 6 connects with the second interface 5 on the original hatch cover 2.

[0037] S4: Repeat S2 and S3 until the hatch covers 2 are stacked to a specified number; at this time, the electrical connectors 3 on each hatch cover 2 are connected in sequence to form an assembly-type main connector 11, and the stacked hatch covers 2 are connected in parallel to the assembly-type main connector 11.

[0038] S5: The charging terminal at the bottom of the assembled main connector 11 is electrically connected to the charging output interface 9 on the charging station 8. Based on the number of stacked hatch covers 2, the charging output interface 9 outputs appropriate current and voltage to charge the several hatch covers 2 connected in parallel.

[0039] For charging output port 9, if it is as shown in the attached document... Fig. 1As shown, the charging output interface 9 is fixedly installed on the ground of the charging station 8. When placing the first hatch cover 2 on the charging station 8, the electrical connector 3 of the first hatch cover 2 needs to be aligned with the charging output interface 9. If the charging output interface 9 is in the form of a charging gun, then after all the electrical connectors 3 are connected to the assembled main connector 11, the charging output interface 9 can be connected to the bottom end of the assembled main connector 11.

[0040] Since all hatch covers 2 are of equal height and the electrical connectors 3 are installed at the same height on the hatch covers 2, the measured value of the corresponding telescopic stroke measuring mechanism is fixed as L when the telescopic mechanism 4 extends to the point where the first interface 6 and the second interface 5 are exactly aligned on two adjacent stacked hatch covers 2.

[0041] In S2, as the first interface 6 moves downward with the telescopic mechanism 4, the maximum measurement value of the telescopic stroke measuring mechanism is used to determine whether the first interface 6 and the second interface 5 have completed docking.

[0042] If the maximum measured value of the telescopic stroke measuring mechanism is exactly L, it means that the first interface 6 and the second interface 5 have completed docking.

[0043] If the maximum measured value of the telescopic stroke measuring mechanism is not L, it indicates that the first interface 6 and the second interface 5 are misaligned. When the first interface 6 and the second interface 5 are misaligned, there may be two situations.

[0044] In the first case, the first interface 6 and the second interface 5 are significantly misaligned, and the first interface 6 is directly inserted into the void. In this case, the telescopic mechanism 4 can extend directly to its limit, and the actual maximum measurement value of the telescopic stroke measuring mechanism will exceed L. For example, if L is 30cm, the measurement value will be 50cm when the telescopic mechanism 4 extends to its limit.

[0045] In the second scenario, the misalignment between the first interface 6 and the second interface 5 is relatively small. The first interface 6 moves down to abut against a blocking component. Since the blocking heights of the various blocking components around the second interface 5 are different, the actual maximum measurement value of the telescopic stroke measuring mechanism can be used to determine which blocking component the first interface 6 is abutting against, thus determining the relative position of the first interface 6 and the second interface 5. Subsequently, the telescopic mechanism 4 is retracted, and then, based on the positional information of the blocking component abutting against the first interface 6, the position of the hatch cover 2 is adjusted using a crane. Then, the telescopic mechanism 4 is used to reconnect the first interface 6 and the second interface 5. With the guidance of the positional information, it is easier to adjust the hatch cover 2 to the correct position.

[0046] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
