[0033] Embodiment 2
[0034] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the second embodiment of the utility model, based on the previous embodiment, protection mechanism 3 includes heat insulation plate 304 fixedly connected to the inner wall of fixed shell 202, and the outer surface of battery replacement cabinet body 1 is hinged with access door plate 301, and the inner wall of fixed shell 202 is fixedly connected with suction fan 305 and blower 306.
[0035] The specific protection mechanism 3 further comprises a filter screen 303 fixedly connected to the outer surface of the fixed shell 202, the outer surface of the filter screen 303 is fixedly connected to the outer surfaces of a suction fan 305 and a blower fan 306, the suction fan 305 and the blower fan 306 are arranged in a staggered manner, and a motor 307 is fixedly connected to the inner wall of the fixed shell 202 near the side of the blower fan 306. An output shaft of the motor 307 is fixedly connected with a cleaning rod 302 penetrating through the outer surface of the fixed shell 202, and the outer surface of the cleaning rod 302 is slidingly connected to the outer surface of the filter screen 303.
[0036] Further, the suction fan 305 and the blower fan 306 work in cooperation, which can not only enhance the air flow rate in the fixed shell 202 to achieve cooling, but also filter the air through the filter screen 303 to prevent dust and smoke from corroding the electrical components.

[0037] Working principle: During the daily operation of the battery replacement cabinet, the temperature sensor 206 and the smoke sensor 207 continuously monitor the environment in the battery compartment of the battery replacement cabinet body 1. The temperature sensor 206 accurately senses the temperature change in the battery compartment, and the smoke sensor 207 is always vigilant about the abnormal increase of smoke concentration. Once the temperature or smoke concentration in the battery compartment exceeds the pre-set safety threshold, the sensor will immediately transmit this signal to the central controller 203. The central controller 203 quickly processes and analyzes the signal, confirms the abnormal situation, and on one hand sends an alarm signal to the alarm module 204 to trigger the sound and light alarm 201 to work. The sound and light alarm 201 immediately emits strong flashes and piercing squeals, forming a prominent warning effect in the surrounding environment, attracting the attention of passing pedestrians, so that they can timely detect the possible dangerous situation of the battery replacement cabinet. On the other hand, the central controller 203 transmits detailed alarm information to the monitoring center quickly and accurately through the communication module 205 by means of reliable wired communication such as Ethernet. After receiving the alarm, the staff of the monitoring center can take corresponding emergency measures in the first time, such as arranging technical personnel to go to the scene to troubleshoot or guiding the on-site personnel to carry out preliminary treatment, to ensure that the safety hazards of the battery replacement cabinet are solved in time.
[0038] At the same time, the heat insulation plate 304 plays a key role in heat insulation. It effectively blocks the heat in the battery replacement cabinet body 1 from transmitting upward, and builds a reliable thermal protection barrier for the electrical components in the fixed shell 202, avoiding damage to the electrical components caused by high temperature, and ensuring the normal and stable operation of the alarm mechanism 2. In order to maintain the appropriate temperature in the fixed shell 202, the air suction fan 305 and the air blower 306 work together. After the air suction fan 305 is started, the hot air in the fixed shell 202 is quickly sucked out, forming a local negative pressure environment. The air blower 306 blows fresh air filtered by the filter screen 303 into the fixed shell 202. The fine filtering function of the filter screen 303 ensures that the air entering is pure and free of impurities, effectively preventing pollutants such as smoke and dust from eroding and damaging the internal electrical components. The air suction fan 305 and the air blower 306 are arranged in a staggered manner, which greatly enhances the flow rate of air in the fixed shell 202, speeds up the heat dissipation, and thus efficiently reduces the temperature in the fixed shell 202, ensuring that the electrical components work in a good temperature environment. When it is necessary to maintain and repair the battery compartment in the battery replacement cabinet body 1, the operator only needs to simply rotate the maintenance door plate 301 to conveniently open the battery compartment and carry out comprehensive inspection, repair and maintenance work, ensuring that the battery replacement cabinet is always in good operating condition.
