[0050] The battery panel monomer 2 is provided with an electric connection jack 201, the battery panel monomer 2 is connected in series or parallel through the electric connection jack 201, so as to charge and discharge externally, the connection between the electric connection jacks 201 is realized through flexible wires, so as not to affect the movement of the battery panel monomer 2, and the axial flow fan 501 is arranged on the fan module 5 and is distributed in a matrix form.

[0051] The anti-seismic battery energy storage station for the ship is used, a plurality of groups of pressure regulating valves 302 are communicated with the compressed gas source through the gas pipeline, the compressed gas passes through the pressure regulating valve 302, reaches the different corrugated supporting capsules 4 through the airflow inner path 301, the battery panel monomers 2 are separated from each other to form gaps, the supporting weight of the corrugated supporting capsules 4 from the bottom to the top decreases in steps, the gas pressure in the corrugated supporting capsules 4 is increased from the bottom to the top in steps through the gas pressure value of the pressure regulating valve 302, and the gap distance between the battery panel monomers 2 is equal under the condition that the ship is stable. Figure 6 and Figure 8 As shown in the drawings, the position height of the telescopic clamping tongue 710 corresponds to the array clamping groove 713.

[0052] When the ship faces an emergency such as a storm, the swing amplitude is large, the electromagnet module 706 is powered on, and the compressed gas in the corrugated supporting capsule 4 is released, at this time, the battery panel monomers 2 are moved downward and combined, the gravity center of the energy storage station is lowered, and the stability of the ship is improved.

[0053] In the case of ship stability, the gap distance between the battery panel monomer 2 is equal, and the telescopic clamping tongue 710 is in high correspondence with the position of the array clamping groove 713; At this time, the control electromagnet module 706 is powered off, so that the action side plate 707 is released, and under the elastic pushing force of the separation spring 712, the action side plate 707 is separated and moved, so that the telescopic clamping tongue 710 is inserted into the array clamping groove 713 for locking, and at this time the sliding block 703 will keep synchronous motion with the side eaves 3;

[0054] As shown in Figure 6 , here the side eaves 3 corresponds to the corrugated support bag 4 at the bottom position, when the ship is running, when the sea waves are up and down, the battery panel monomer 2 will move relative to the warehouse body frame 1, once the battery panel monomer 2 moves up, it will inevitably impact the return, and a large impact pressure will be generated on the corrugated support bag 4; When the battery panel monomer 2 moves up, the side eaves 3 drives the piston body 716 to move up synchronously through the sliding block 703, at this time the corrugated support bag 4 is stretched, as shown in Figure 9 , control the negative pressure of the gas circuit 718, the one-way plug 721 will move down to open; When the battery panel monomer 2 moves down, the piston body 716 moves down synchronously, so that the control gas circuit 718 is in a positive pressure state, at this time the one-way plug 721 remains closed, and can only be discharged through the air micro hole 723, thereby making the piston body 716 generate a downward moving resistance, assisting the support of the downward impact movement of the battery panel monomer 2, reducing the instantaneous impact pressure borne by the corrugated support bag 4, and prolonging the service life of the corrugated support bag 4 at the bottom position.

[0055] And through the flexible support of the corrugated support bag 4 to the battery panel monomer 2, the energy storage station has the anti-seismic property in the up-down direction, which can buffer the impact force in the up-down direction when the ship collides with the bottom, and improve the protection effect of the battery panel monomer 2.
