Therefore, the applicant designed an electric vehicle battery charging cabinet with an automatic fire extinguishing device. When the battery explodes and other dangerous situations occur, the self-igniting electric vehicle batteries can be isolated and extinguished. Utility Model Content

The battery of the electric vehicle is placed inside and plugged into the charging socket 5 for charging. When the battery of the electric vehicle catches fire spontaneously, the smoke alarm 6 senses the smoke generated by the battery of the electric vehicle and cuts off the power supply of the charging socket 5. Then the separation mechanism 7 pushes the battery of the electric vehicle to move and separate from the charging socket 5, and then the battery of the electric vehicle is discharged from the battery compartment 2 from the discharge port through the electronic control unit 8 and moved to the battery dropping channel 3. The battery of the electric vehicle falls into the isolation compartment 4 in the battery dropping channel 3, and the self-igniting battery of the electric vehicle is isolated from the battery of the electric vehicle in the battery compartment 2. When the temperature in the isolation compartment 4 reaches the preset temperature (170 degrees Celsius) of the hot aerosol fire extinguishing device 13, it automatically starts, and the hot aerosol fire extinguishing device 13 extinguishes the burning battery, thereby realizing automatic fire extinguishing of the self-igniting battery, reducing the impact of the fire on other batteries, and reducing safety hazards and property losses.

[0020] As an implementation method of this embodiment, Figure 1As shown, a baffle door 9 is provided at the discharge port of the battery compartment 2, and the top end of the baffle door 9 is movably hinged to the battery compartment 2, and an electromagnetic lock 10 for fixing the baffle door 9 is installed at the bottom end of the baffle door 9 inside the cabinet body 1, and the electromagnetic lock 10 is electrically connected to the controller of the charging cabinet. The electromagnetic lock 10 and the baffle door 9 are used to close the discharge port of the battery compartment 2 to avoid influence between the battery compartments 2. When the battery in the current battery compartment 2 spontaneously ignites, the electromagnetic lock 10 is powered off and closed, so that the battery discharged from the battery compartment 2 can push the baffle door 9 open, thereby falling into the battery drop channel 3.

[0021] As an implementation method of this embodiment, Figure 1 As shown, the separation mechanism 7 includes a second electric push rod installed in the battery compartment 2, and the output end of the second electric push rod is fixedly connected to a push plate. The second electric push rod drives the push plate to move the battery of the electric vehicle away from the charging socket 5. When the battery in the current battery compartment 2 spontaneously ignites, the second electric push rod drives the push plate to quickly separate the battery of the electric vehicle from the charging socket 5, so as to facilitate the discharge and isolation of the battery of the electric vehicle.

[0022] As an implementation method of this embodiment, Figure 2 As shown, the electric control unit 8 includes a base 802, a connecting seat 801 is fixedly connected to the bottom end of the battery compartment 2 near the discharge port, one end of the base 802 is movably hinged to the connecting seat 801, a mounting groove is opened at the bottom end of the battery compartment 2, a first electric push rod 803 is fixedly installed in the mounting groove, a sliding block 804 is fixedly connected to the output end of the first electric push rod 803, the sliding block 804 is slidably installed in the mounting groove, a connecting block 805 is fixedly connected to the bottom of the base 802, and an adjusting rod is movably hinged between the connecting block 805 and the sliding block 804 806, the battery of the electric vehicle is placed on the base 802 for charging. After the battery of the electric vehicle is separated from the charging socket 5, the first electric push rod 803 works to push the sliding block 804 to move, thereby changing the angle of the adjustment rod 806, and turning the adjustment rod 806 from a horizontal state to a vertical state, thereby rotating the base 802 around the connecting seat 801, so that the base 802 is tilted, and the battery of the electric vehicle slides down with the tilted base 802, slides from the discharge port of the battery compartment 2 into the battery drop channel 3, and falls into the isolation compartment 4 for isolation and fire extinguishing.

[0023] In this embodiment, if Figure 2 As shown, a support block 807 is fixedly connected to the bottom of the battery compartment 2 and corresponds to the movable end of the base 802. When the base 802 is rotated to a horizontal position, the base 802 overlaps the support block 807 to provide a stable support for the base 802 for placing the battery of the electric vehicle.

[0024] As an implementation method of this embodiment, Figure 1As shown, a pair of rotating plates 11 are provided at the openings corresponding to the isolation compartment 4 and the battery dropping channel 3. The ends of the pair of rotating plates 11 that are away from each other are rotatably connected to the isolation compartment 4 through stainless steel spring hinges. When the battery of the electric vehicle that spontaneously combusts in the battery dropping channel 3 falls into the isolation compartment 4, the rotating plate 11 is automatically closed by the stainless steel spring hinge to reduce the impact of the fire on the batteries in other battery compartments 2.

[0025] As an implementation method of this embodiment, Figure 1 As shown, a material guide platform 12 is fixedly connected to the bottom end of the isolation chamber 4, and the top of the material guide platform 12 is inclined. The inclination direction is that the battery drop channel 3 is inclined downward toward the direction of the hot aerosol fire extinguishing device 13. The self-igniting battery that falls into the isolation chamber 4 is placed on the material guide platform 12. As the inclined surface of the material guide platform 12 slides to the hot aerosol fire extinguishing device 13, the self-igniting battery can be better extinguished.

[0026] The control method of the present invention is controlled by the controller of the charging cabinet. The control program of the controller can be realized by simple programming by technicians in this field, so the present invention no longer explains the control method and circuit connection in detail; when the battery of the electric vehicle spontaneously ignites, a signal is obtained through the smoke alarm 6. When it is determined that the battery of the electric vehicle spontaneously ignites, the controller is pushed to the system background in time, and the relevant staff is notified to deal with it through software push, text message or automatic telephone voice.

[0027] Working principle: When in use, place the battery of the electric vehicle in the battery compartment 2 and plug it into the charging socket 5 for charging. When the battery of the electric vehicle ignites spontaneously, the smoke alarm 6 senses the smoke generated by the battery of the electric vehicle and cuts off the power supply of the charging socket 5. The second electric push rod drives the push plate to quickly separate the battery of the electric vehicle from the charging socket 5. The first electric push rod 803 works to push the sliding block 804 to move, change the angle of the adjustment rod 806, and move the adjustment rod 806 from a horizontal state to a vertical state, so that the base 802 is around The connecting seat 801 rotates to tilt the base 802, and the battery of the electric vehicle slides down with the tilted base 802, slides into the battery drop channel 3 from the discharge port of the battery compartment 2, and falls into the isolation compartment 4. The rotating plate 11 is automatically closed by the stainless steel spring hinge, and the hot aerosol fire extinguishing device 13 is automatically started when the temperature in the isolation compartment 4 reaches the preset temperature. The hot aerosol fire extinguishing device 13 extinguishes the burning battery, realizes automatic fire extinguishing of the self-igniting battery, reduces the impact of the fire on other batteries, and reduces safety hazards and property losses.

[0028] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
