[0020] The cleaning component includes a movable plate 101, a partition 103 and a first electric slider 104; a plurality of movable plates 101 are slidably connected in the charging cabinet 1; each movable plate 101 is located in an adjacent storage cavity 1002; each storage cavity 1002 is provided with four slide grooves 1003; each slide groove 1003 is slidably connected with a first electric slider 104; the four first electric sliders 104 located in the same storage cavity 1002 are commonly fixed to the movable plate 101; a partition 103 is fixed to the front side of the movable plate 101; a powder storage cavity 10101 is commonly provided between the movable plate 101 and the partition 103; the powder storage cavity 10101 is initially filled with dry powder.

[0021] It also includes a second electric slider 105, a temperature sensor 106 and a slide plate 107; each slide groove 1003 is slidably connected to a second electric slider 105; the four second electric sliders 105 located in the same storage cavity 1002 are commonly fixed to the slide plate 107; and each slide plate 107 is fixed to the front side with a temperature sensor 106.

[0022] It also includes a protective valve 102; a plurality of holes are provided on the movable plate 101, and each hole is provided with a one-way membrane opened forward; two avoidance holes are provided on the movable plate 101; two protective valves 102 are fixedly connected to the movable plate 101; each protective valve 102 is located in an adjacent avoidance hole; each protective valve 102 is composed of a plurality of arc-shaped valves, and each protective valve 102 is made of rubber material.

[0023] The movable plate 101 is always attached to the inner wall of the charging cabinet 1 .

[0024] The partition 103 is made of fiber reinforced plastic, which is convenient for burning through the partition 103 in time to spray out the dry powder, so as to extinguish the burning battery in time and prevent the fire from spreading.

[0025] Each air outlet 1004 is close to the connection between the battery and the pin 5001.

[0026] The sides of the movable plate 101 are all set to be inclined to reduce the friction between the movable plate 1 and the charging cabinet 1. At the same time, the inclined surface is not easy to accumulate dust, preventing impurities from accumulating on the sides of the movable plate 101 and affecting the movement.

[0027] Before charging the battery in the charging cabinet 1, the photovoltaic panel 3 absorbs sunlight and converts it into electrical energy, which is then stored in the battery 5. When the battery 5 is fully charged, it is directly connected to the battery through the pin 5001 for charging, thereby achieving energy saving. At the same time, during the charging process, gas is pumped to the gas outlet 1004 through an external pumping device, and the gas is discharged from the heat dissipation port 1001 after passing through the battery, so as to dissipate heat while the battery is charging to prevent it from being overheated and damaged.

[0028] In the above process, considering that in the rainy season, when placing the battery, water droplets are easily attached to the surface of the battery. When the user does not wipe the water droplets on the surface of the battery and puts it into the storage chamber 1002 for charging, the surface moisture is easy to flow along the battery to the plug-in place, and there is a risk of leakage and short circuit. The existing method only sets a drainage area on the lower side of the storage chamber 1002 to make the water flow along the surface of the battery to the drainage area to drain the water. However, this method cannot prevent the water from flowing through the plug-in place of the battery during the downward flow and causing a short circuit. Moreover, after long-term use, the surface of the battery is easy to adhere to dust, which affects the heat dissipation of the battery during the charging process. In order to avoid this A phenomenon that when the user pushes the battery into the storage chamber 1002, the battery first contacts the movable plate 101, pushing the movable plate 101 to move backward, and then squeezing the protective airbag 4 to shrink, so that the gas in the protective airbag 4 breaks the one-way membrane on the movable plate 101 and sprays out from the hole, thereby acting on the surface of the battery. Since the battery connection is located at its rear side, when the gas blows towards the battery, the water droplets attached to the surface of the battery are affected by the gas and flow forward, making it impossible to flow to the battery connection. In this process, the water blown to the front side of the battery can flow downward along its surface normally, thereby not affecting the normal charging of the connection.

[0029] In the above process, when the battery is overheated, overcharged or short-circuited during charging, the battery may expand and catch fire. At this time, the temperature in the storage chamber 1002 continues to rise, and the temperature sensor 106 detects the abnormal temperature and sends a signal alarm. At the same time, the first electric slider 104 is started to slide forward in the slide groove 1003, thereby driving the movable plate 101 to move forward, so that the burning battery moves forward, and the battery is separated from the pin 5001 to stop power supply. When the battery burns, the fire burns through the partition 103, causing the dry powder in the powder storage chamber 10101 to leak out, and then the battery is extinguished, so that the emergency power off is achieved and the battery is extinguished as soon as possible to reduce losses.

[0030] It is also considered that when a dry powder fire extinguisher is used to extinguish a battery fire, the dry powder is fine and easily scattered in various areas of the storage chamber 1002. When a large amount of dry powder adheres to the pin 5001, the pin 5001 will be short-circuited due to the influence of the dry powder, resulting in a secondary fire. In order to avoid this phenomenon, when the movable plate 101 pushes the battery forward, the protective valve 102 on the movable plate 101 gradually moves away from the pin 5001. It should be noted that when the battery pushes the movable plate 101 to move backward, the pin 5001 pushes the protective valve 102 open. 2 is plugged into the battery socket. When the pin 5001 and the movable plate 101 gradually move away from each other, the elastic material used in the protective valve 102 makes the curved valve on the protective valve 102 lose the restriction of the pin 5001 and close again. Since the pin 5001 is always in the protective airbag 4, when the protective valve 102 is closed, the pin 5001 is in a completely enclosed space. When the dry powder is used to extinguish the fire, the pin 5001 is enclosed and is not affected by the dry powder, thereby avoiding a short circuit and causing a secondary fire.

[0031] After using a dry powder fire extinguisher to extinguish the battery fire, considering that the dry powder is difficult to clean and increases the manual workload, the first electric slider 104 is started to move back and forth, so that the movable plate 101 is fitted in the storage cavity 1002 and moves back and forth, thereby scraping off the dry powder adhering to the storage cavity 1002. At the same time, in the process of the movable plate 101 moving backward, the gas can be blown out by squeezing the protective airbag 4, thereby blowing off the dry powder scraped off the storage cavity 1002, thereby reducing the manual workload. It should be noted that: since the surface of the protective airbag 4 is coated with a fire-retardant coating, the protective airbag 4 is not easily burned through by fire.

[0032] During the process of extinguishing a battery fire with dry powder, in order to improve the fire extinguishing effect, when the temperature sensor 106 is triggered, the second electric slider 105 is synchronously started to slide forward, thereby driving the slide plate 107 to slide forward, so that the movable plate 101 and the slide plate 107 synchronously drive the protective airbag 4 to slide forward for a distance. At this time, the movable plate 101 stops moving, and the second electric slider 105 continues to drive the slide plate 107 to slide forward, thereby compressing the air in the protective airbag 4, so that the dry powder leaks out from the powder storage chamber 10101 and is dispersed in the storage chamber 1002 by the gas, and the storage chamber 1002 is fully covered and extinguished, thereby improving the fire extinguishing effect of the device. During the process of the slide plate 107 sliding forward, since the air outlet 1004 is close to the plug-in point between the battery and the pin 5001, the slide plate 107 slides forward and passes over the air outlet 1004, and the air discharged from the air outlet 1004 is isolated, so that The air cannot flow to the battery, thereby cutting off the air supply to the battery area at this time, so that the battery has no oxygen supply when burning, and the fire extinguishing effect is further improved in conjunction with a dry powder fire extinguisher. When the protective airbag 4 is stretched and reset, the one-way membrane located at the air inlet 4001 opens, so that the gas discharged from the air outlet 1004 is replenished into the protective airbag 4 again through the air inlet 4001. At the same time, the backward movement speed of the movable plate 101 is limited during the backward sliding of the first electric slider 104 to prevent the worker from damaging the pin 5001 when quickly inserting the battery plug into the pin 5001, and to provide buffer protection for the pin 5001. When the first electric slider 104 moves forward, the protective airbag 4 is unfolded, so that the movable plate 101 and the protective airbag 4 cover the pin 5001, thereby preventing dust and moisture from adhering to the pin 5001 when it is not in use.

[0033] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 6 As shown, it also includes a top column 201; the front side of the partition 103 is fixedly connected to two top columns 201.

[0034] Each top column 201 is provided with an electric suction cup on the front side.

[0035] When the user pushes the battery into the storage cavity 1002 for charging, the movable plate 101 is attached to the rear side of the battery at this time, which will affect the heat dissipation of the rear side of the battery. In order to avoid this phenomenon, the top column 201 is used to contact the rear side of the battery so that the battery does not contact the movable plate 101, thereby avoiding the phenomenon of poor heat dissipation of the battery. At the same time, the air discharged from the air outlet 1004 directly flows between the battery and the movable plate 101, and then directly acts on the area where the battery and the pin 5001 are more seriously heated. At the same time, since a suction cup is provided on the front side of the top column 201, when the battery contacts the top column 201, the suction cup is adsorbed on the battery. On the surface, when the user needs to put the battery into the higher storage cavity 1002 of the charging cabinet 1 for charging, in order to avoid being unable to push the battery completely into the storage cavity 1002 and plug it into the pin 5001, after the battery is adsorbed by the electric suction cup on the top column 201, the first electric slider 104 is started to slide backward, driving the movable plate 101, the partition 103 and the top column 201 to move backward, and then actively driving the battery to be inserted into the pin 5001, which is convenient for the user. At the same time, in the process of the movable plate 101 moving backward, the gas in the protective airbag 4 is squeezed to blow towards the battery, and the dust adhering to the surface of the battery can also be blown away to ensure the heat dissipation of the battery.
