At the same time, the protective plate 406 is between the two sets of light bars 4 04 is guided to rise, and the raised protective plate 406 seals the air outlet 203, thereby preventing the high-temperature smoke inside the battery pack chamber 104 from entering the air outlet 203 and damaging the heat dissipation fan 204. While the protective plate 406 is raised to seal the air outlet 203, the protective plate 406 drives the baffle 514 to rise, thereby releasing the signal blocking of the photoelectric signal transmitter 512 and the photoelectric signal receiver 513. When the photoelectric signal receiver 513 receives the photoelectric signal of the photoelectric signal transmitter 512, the controller opens the solenoid valve 509, so that the carbon dioxide inside the carbon dioxide cylinder 501 enters the injection pipe 506 through the gas delivery valve 504 and the three-way pipe 505. The carbon dioxide entering the injection pipe 506 enters the multiple groups of branch pipes 507 respectively and is sprayed to the inside of the battery pack chamber 104 through the nozzle 508, thereby performing a fire extinguishing operation on the fire inside the battery pack chamber 104, and realizing timely fire extinguishing.

[0044] The controller, smoke sensor 308, cooling fan 204, electric hydraulic cylinder 307, solenoid valve 509, photoelectric signal transmitter 512 and photoelectric signal receiver 513 of a battery energy storage cabin of the present invention are purchased on the market. Technicians in the industry only need to install and operate them according to the accompanying instruction manual, without the need for creative labor by technicians in this field.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
