Description

Technical Field

[0001] This invention belongs to the field of ship battery swapping technology, and more specifically, relates to a docking connection device and its control method for installing battery boxes on ships. Background Technology

[0002] Large electric vessels typically employ frame-type or containerized power battery boxes. Battery modules are installed within a metal load-bearing frame, and the battery box is installed into or removed from the hull as a whole using lifting equipment. To improve battery swapping efficiency, the interface ends of connectors such as power connectors, low-voltage connectors, and communication connectors, as well as optional liquid-cooled interface ends, can be centrally located at the bottom of the battery box and vertically connected to the mating end located in the middle of the ship's load-bearing base.

[0003] The top-to-bottom connection method reduces the footprint of the battery box, but it also introduces new sealing challenges. On ships, the connection points are typically upward-facing, making them susceptible to entry of rainwater, deck wash water, salt spray deposits, and condensation. The bottom interface of the battery box may also be exposed to moisture and salt spray during hoisting and temporary storage. If the connector is inserted directly without establishing a sealed environment, residual moisture may enter the high-voltage contact area, causing insulation degradation, increased contact resistance, or electrochemical corrosion.

While preferred embodiments of the invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0023] like Figures 2-6 As shown, the present invention provides a docking connection device for installing a battery box on a ship, the docking connection device comprising: At least one connector, the connector including an interface end 1 and a docking end 2; The sealing layer 3 and the first sealing mechanism 4 are provided. The sealing layer 3 is located at the bottom of the battery box 5, the interface end 1 is located in the middle of the sealing layer 3, and the first sealing mechanism 4 is used to open and close the interface end 1. The annular sealing seat 14 and the second sealing mechanism 6 are provided. The annular sealing seat 14 is installed on the ship 7, and the docking end 2 is installed inside the annular sealing seat 14. The second sealing mechanism 6 is used to open and close the docking end 2. The sealing layer 3 is used to fit with the annular sealing seat 14 when the battery box 5 is hoisted onto the ship 7 to form a sealed cavity. Locking mechanism 8 is provided at the bottom of battery box 5 and on vessel 7, and battery box 5 and vessel 7 are detachably connected by locking mechanism 8; Drainage and dehumidification component 9, which is connected to the interior of the sealed cavity; The lifting docking platform 10 is located inside the annular sealing seat 14, and the docking end 2 is located on the lifting docking platform 10. The docking end 2 is used to insert or pull out the interface end 1 when the lifting docking platform 10 is lifted or lowered. The controller is electrically connected to the first sealing mechanism 4, the second sealing mechanism 6, the locking mechanism 8, the drainage and dehumidification component 9, and the lifting docking platform 10.

[0024] Specifically, to address the current issue of connecting ships and battery boxes via connectors, which reduces the footprint of the battery box but leads to water accumulation at the connector joints and potential moisture intrusion causing circuit malfunctions, this application provides a docking connection device for installing battery boxes on ships. During the hoisting of the battery box 5 onto the ship 7 and the connection of the connectors, this device first controls the sealing layer 3 to fit snugly against the annular sealing seat 14. Then, the controller controls the locking mechanism 8 to lock the battery box 5 onto the ship 7, ensuring the sealing layer 3 and the annular sealing seat 14 are pressed tightly together. This creates a sealed cavity inside the annular sealing seat 14, isolating it from the external marine environment. When the sealed cavity contains water or has high humidity, the drainage and dehumidification components drain and dehumidify the sealed cavity. After drainage and dehumidification, the first sealing mechanism 4 and the second sealing mechanism 6 are opened. Subsequently, the lifting docking platform 10 is controlled to raise the docking end 2 and connect it to the interface end 1 at the bottom of the battery box 5, thus completing the docking installation of the battery box 5. Using this docking connection device can reduce the entry of rainwater, salt spray and condensation into the contact area.

[0025] During the process of lifting the battery box 5 to the ship 7 and disconnecting the connector, the docking connection device can first disconnect the high-voltage circuit and confirm that the interface is in a zero-energy state. Then, the controller controls the lifting docking platform 10 to drive the docking end 2 to descend and separate from the interface end 1 at the bottom of the battery box 5. After the docking end 2 and the interface end 1 are separated, the first sealing mechanism 4 and the second sealing mechanism 6 are controlled to close. Then, the locking mechanism 8 is controlled to unlock. At this time, the battery box 5 can be lifted off the ship 7. After the battery box 5 is removed, the interface end 1 and the docking end 2 are independently sealed by the first sealing mechanism 4 and the second sealing mechanism 6, respectively, improving the protection capability during transportation, waiting and deck washing.

[0026] When the docking connection control method uses the docking connection device for docking, it constructs a docking method of sealing first, opening the cover, and then inserting. After the battery box 5 is placed and mechanically locked, a sealed cavity is formed first.

[0031] Specifically, to address the issues arising from the large mass of the battery box and the resulting lateral, longitudinal, and angular errors during hoisting and positioning, and the potential for lateral shear loads if the docking end on the vessel 7 is directly and rigidly inserted, and the potential for tension on the connector, contact damage, or interference when the battery box is lifted if the connection is executed before the mechanical lock is engaged, or if the mechanical lock is released before the connector is fully disengaged, this application designs a floating plate 11 on the lifting docking platform 10. Utilizing multiple return springs 12 and at least one horn-shaped interface end 1 or a conical docking end 2, the floating plate 11 can move horizontally, making contact before the electrical contacts, thus gradually aligning the interface end 1 and the docking end 2. This absorbs the lateral, longitudinal, and insertion depth errors of the battery box 5, reducing the lateral shear load on the connector.

[0032] Preferably, the docking connection device for installing battery boxes on ships further includes: An annular support seat 15 is installed on the ship 7, and an annular sealing seat 14 is installed inside the annular support seat 15.

Before the connector is inserted, the dryer 901 can be used for purging, and the air pressure sensor can be used to perform a pressure holding test. If water is detected by the liquid detection sensor, the controller controls the drainer 902 to open.

[0049] like Figure 1 As shown, a docking connection control method for installing a battery box on a ship controls a docking connection device for installing a battery box on a ship.

The system detects the humidity and water accumulation inside the sealed cavity. When the dryness condition does not meet the preset conditions, it controls the operation of the drainage and dehumidification component 9 to ensure that the dryness condition of the sealed cavity meets the preset conditions. When the drying condition meets the preset conditions, the first sealing mechanism 4 and the second sealing mechanism 6 are controlled to open.
