[0044] A method for storing energy in a new energy storage cabinet, the specific operation steps are as follows:

[0045] The battery pack 23 is installed in the battery compartment 25, and then the energy converter body 27 is installed in the second placement chamber, and the energy converter body 27 is electrically connected to the battery pack 23 through a wire, and the energy converter body 27 is electrically connected to an external power source;

[0046] During the night: the external alternating current will flow into the energy converter body 27 through the wire, and the energy converter body 27 will convert the alternating current into direct current, and then the direct current will be stored in the battery pack 23, so as to realize the storage of electric energy;

[0047] During the day or during power outages, the electric energy of the battery pack 23 flows into the energy converter body 27 through the wires, and the direct current is converted into alternating current through the energy converter body 27, and then transmitted to the device for use, thereby releasing the electric energy.

[0048] Working principle: When the present invention is in use, when the energy storage cabinet is storing or discharging energy, the battery pack 23 generates heat naturally; at this time, the micro motor 17 is started, and the output shaft of the micro motor 17 rotates to drive the screw rod 19 to rotate, thereby driving the threaded sleeve 18 to move downward, thereby driving the rectangular plate 32 to move downward, and the downward movement of the rectangular plate 32 will drive the long rod 22, the traction rope 41 and the short cylinder 42 to move downward;

[0049] The downward movement of the traction rope 41 drives the turntable 30 to rotate, and then drives the coil spring shaft 29 to rotate, thereby releasing the fire blanket 35; while the short cylinder 42 slides downward along the vertical slot 33, the long rod 22 also moves downward along the L-shaped slot 28, thereby driving the fire blanket 35 to move downward; and when the short cylinder 42 moves to the bottom of the vertical slot 33, at this time, the fire blanket 35 moves to the front of the battery compartment 25, and then as the rectangular plate 32 continues to move downward, one end of the rectangular plate 32 is limited by the short cylinder 42, causing the rectangular plate 32 to rotate, thereby driving the long rod 22 to move toward the end of the L-shaped slot 28, so that the fire blanket 35 moves to the bottom of the battery compartment 25, and finally, the adsorption force between the U-shaped soft magnet 24 and the U-shaped soft magnet 1 2 makes the fire blanket 35 tightly fit on the front end surface of the battery compartment 25, avoiding air circulation, which is conducive to fire extinguishing;

[0050] Among them, when the rectangular plate 32 moves downward, the connecting rod 31 will be folded and moved downward, thereby driving the connecting frame 16 to move downward, and then under the action of the extrusion spring 240, the U-shaped frame 14 will move downward, thereby driving the blocking plate 5 to move downward, and when the U-shaped frame 14 moves to the bottom of the U-shaped frame 17, at this time, the blocking plate 5 will block all the air outlets 6 to prevent the circulation of air in the battery compartment 25; then, as the rectangular plate 32 continues to move downward, the connecting frame 16 will continue to move downward. At this time, the U-shaped frame 14 will not move, and then when the connecting frame 16 moves downward, it will drive the resistance plate 15 to move downward, and then drive the connecting rod 14 to move downward, thereby driving the piston 21 to move downward, further causing the gas in the negative pressure box 10 to be extracted, so that the pressure in the negative pressure box 10 is less than the external pressure, and when the short cylinder 42 moves to the bottom of the vertical groove 33, at this time, the piston 21 moves to the bottom of the sealing box 12;

[0051] When the end of the long rod 22 moves toward the L-shaped groove 28 (at this time, the fire blanket 35 has wrapped the battery compartment 25), the long rod 22 contacts the pressure sensor 44. At this time, the pressure sensor 44 receives the signal and transmits the signal to the processor in the control device 3. After the processor processes and the controller electric valve 9 is opened, since the pressure in the negative pressure box 10 is lower than the pressure in the battery compartment 25, at this time, the air in the battery compartment 25 will flow into the negative pressure box 10, thereby realizing the extraction of the air in the battery compartment 25, which is convenient for the rapid consumption of oxygen in the battery compartment 25, thereby achieving a rapid fire extinguishing effect;

[0052] After the fire is extinguished, the air micromotor 17 resets the threaded sleeve 18, thereby resetting each component, and the fire blanket 35 is rewound in the circular housing 36 under the action of the winding spring shaft 29.

[0053] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
