[0031] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation.

[0032] The battery compartment structure of the pure electric ship shown in Figure 1-4 includes a stern deck 1; a battery compartment 2 is provided in the stern deck 1; an exit door 3 is provided at one end of the battery compartment 2, and an installation block 4 is provided at the other end of the battery compartment 2; a conveyor 5 is provided between the exit door 3 and the installation block 4; a battery pack 6 is provided on the conveyor 5; a locking assembly 7 is provided on the installation block 4; the locking assembly 7 is connected to the battery pack 6; a controller 8 is connected to the locking assembly 7; and the controller 8 is connected to the conveyor 5.

[0033] The battery compartment 2 is equipped with a conveyor 5; when the battery pack 6 catches fire, the controller 8 controls the locking component 7 to unlock and controls the hatch 3 to open; at the same time, the conveyor 5 is activated to convey the battery pack 6 out of the battery compartment 2 and throw it into the water, thereby effectively preventing the fire from spreading and burning the entire ship, and avoiding greater losses.

[0034] The locking assembly 7 includes a locking motor 701; the locking motor 701 is mounted on the side of the mounting block 4 near the battery pack 6; the locking motor 701 includes a drive shaft 702; the end of the drive shaft 702 is provided with a locking block 703; the battery pack 6 is provided with a locking hole 601 on the side near the locking motor 701; the locking block 703 is provided in the locking hole 601.

[0035] The locking motor 701 is fixedly connected to the side wall of the mounting block 4 by bolts; the drive shaft 702 is fixedly connected to the locking block 703; the locking motor 701 can control the drive shaft 702 to rotate, thereby controlling the rotation of the locking block 703; the locking hole 601 is provided on the side wall of the battery pack 6; the locking block 703 extends into the locking hole 601.

[0036] A limiting baffle 704 is provided at one end of the locking hole 601 near the battery pack 6; an unlocking groove 705 is provided on the limiting baffle 704; a locking block 703 is provided in the locking hole 601, and the locking block 703 abuts against the limiting baffle 704.

[0037] The limiting baffle 704 is fixedly connected in the locking hole 601, and the locking block 703 enters the locking hole 601 through the unlocking groove 705. When the battery pack 6 and the locking block 703 are locked, the locking block 703 is located inside the locking hole 601 and abuts against the limiting baffle 704. When it is necessary to unlock the battery pack 6 and the locking block 703, the locking motor 701 controls the locking block 703 to rotate 90°, so that the locking block 703 corresponds to the unlocking groove 705. After the conveyor 5 is started, the battery pack 6 moves in the opposite direction to the mounting block 4, so that the locking block 703 is removed from the locking hole 601 through the unlocking groove 705.

[0038] The conveyor 5 includes a conveyor belt 501, a first drive roller 502 and a second drive roller 503; the conveyor belt 501 is mounted on the first drive roller 502 and the second drive roller 503; a plurality of conveyor rollers 504 are provided between the first drive roller 502 and the second drive roller 503.

[0039] The first drive roller 502 and the second drive roller 503 are located at both ends of the conveyor 5. When the conveyor 5 is working, the first drive roller 502 and the second drive roller 503 are driven to rotate by the drive motor 505. Since the conveyor belt 501 is installed on the first drive roller 502 and the second drive roller 503, the conveyor belt 501 moves with the first drive roller 502 and the second drive roller 503 under the action of friction. The multiple conveyor rollers 504 located between the first drive roller 502 and the second drive roller 503 play the role of supporting the conveyor belt 501, reducing the sagging deformation of the conveyor belt 501 during operation, and ensuring that the conveyor belt 501 remains stable, thereby realizing the stable and efficient transportation of the battery pack 6 on the conveyor 5.

[0040] The first drive roller 502 and the second drive roller 503 are both connected to drive motors 505; a baffle 506 is provided on the conveyor belt 501; a stop block 401 is provided on the mounting block 4; the battery pack 6 is pressed against the baffle 506 and the stop block 401.

[0041] The first drive roller 502 and the second drive roller 503 are each independently connected to a drive motor 505, and the controller 8 controls the two drive motors 505 to run synchronously. The first drive roller 502 and the second drive roller 503 both include roller shafts. The roller shafts are fixedly connected to the transmission shafts of the drive motors 505. The stop block 401 is fixedly connected to the mounting block 4 on the side near the battery pack 6, and the stop block 401 is located above the locking motor 701. The baffle 506 is fixedly connected to the top surface of the conveyor belt 501. When the battery pack 6 is in the locked state, the battery pack 6 abuts against the locking block 703, and at the same time abuts against the baffle 506 and the stop block 401 to achieve stable installation and avoid shaking. When the battery pack 6 is unlocked and the conveyor 5 is started, the baffle 506 ensures that the battery pack 6 moves with the conveyor belt 501.

[0042] The stern deck 1 includes a side wall 101; the side wall 101 is provided with a door panel mounting hole 102; the hatch 3 is located in the door panel mounting hole 102 and is connected to the side wall 101 by a hinge 103.

[0043] The door mounting hole 102 provided on the side wall 101 of the stern deck 1 provides an installation position for the hatch 3; the hatch 3 is installed in the door mounting hole 102 and connected to the side wall 101 by a hinge 103, and the hatch 3 can rotate around the hinge 103 to open or close.

[0044] The hatch 3 has a pin hole 301 on the side away from the hinge 103; a cylinder 302 is installed on the side wall 101; the cylinder 302 includes a piston rod 303; the piston rod 303 is located in the pin hole 301.

[0045] The cylinder 302 can drive the piston rod 303 to extend and retract. When it is necessary to close the hatch 3, the piston rod 303 extends and inserts into the pin hole 301 of the hatch 3, fixing the hatch 3 in the door panel mounting hole 102 of the side wall 101, thereby locking the hatch 3. When the controller 8 issues an opening command, the cylinder 302 controls the piston rod 303 to retract and disengage from the pin hole 301, thereby unlocking the hatch 3.

[0046] Cylinder 302, drive motor 505, and locking motor 701 are all connected to controller 8. Controller 8 is a BMS (Battery Management System) controller; controller 8 can control the start, stop, and rotation angle of locking motor 701; controller 8 can control the extension and retraction of cylinder 302; controller 8 can control the synchronous forward and reverse rotation of the two drive motors 505; controller 8 is connected to a buzzer and an alarm light.

[0047] The specific workflow of this utility model is as follows:

[0048] When battery pack 6 catches fire, controller 8 unlocks locking assembly 7 and opens hatch 3; at the same time, conveyor 5 is activated to transport battery pack 6 out of battery compartment 2 and throw it into the water, thereby effectively preventing the fire from spreading and burning the entire ship, and avoiding greater losses.
