DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings. Figure 1-3 :

[0022] A fireproof charging pile for new energy vehicles comprises a box body 1, wherein a DC charging module and an electrical system 2 are arranged in the box body 1, a heat dissipation window is arranged on the side of the box body 1, and the heat dissipation window comprises a plurality of vents 3 and a louver grille 4, an aerosol fire extinguishing device 5 is arranged on the top of the box body 1, and an aerosol nozzle 6 of the aerosol fire extinguishing device 5 faces the inner cavity of the box body 1 below, a movable sealing plate 7 is arranged between the louver grille 4 and the vents 3, and a plurality of flow holes 8 are arranged on the movable sealing plate 7, and the movable sealing plate 7 slides between an open position and a closed position, and when the movable sealing plate 7 is in the open position, the flow holes 8 correspond to the vents 3 one by one and connect the ventilation gap between the inner cavity of the box body 1 and the louver grille 4, and when the movable sealing plate 7 is in the closed position, the flow holes 8 are staggered with the vents 3 and close the vents 3.

[0023] Compare with Figure 1 , the user connects the electric vehicle to the charging pile for charging. Figure 2 As shown, during the charging process, the movable sealing plate 7 is in the open position, and the inner cavity of the box body 1 is connected to the outside through the vents 3, the flow holes 8 and the louver grille 4, and the air circulates normally to provide heat dissipation for the working DC charging module and the electrical system 2. Figure 3 As shown, when a fire occurs, the movable sealing plate 7 is switched to the closed position, the movable sealing plate 7 closes the vent 3, and cuts off the flow channel between the inner cavity of the box body 1 and the outside, so that fresh air from the outside cannot enter the box body 1. The aerosol fire extinguishing device 5 is started to spray aerosol into the box body 1, so as to achieve the effect of rapid fire extinguishing under the condition of isolating the outside air.

[0024] In this embodiment, heat dissipation windows are provided on both sides of the box body 1 , and each heat dissipation window is equipped with a movable sealing plate 7 .

[0025] In this embodiment, the aerosol fire extinguishing device 5 is a heat-sensitive automatic aerosol fire extinguishing device 5. When a fire occurs, the temperature in the box 1 rises abnormally, and the heat-sensitive automatic aerosol fire extinguishing device 5 can be automatically started to extinguish the fire.

[0026] In this embodiment, the movable sealing plate 7 is vertically arranged and slides in the vertical direction, and the open position of the movable sealing plate 7 is located at the uppermost end, and the closed position is located at the lowermost end.

[0027] In this embodiment, the inner side of the movable sealing plate 7 is in contact with the side wall of the box body 1, the vent 3 is provided on the side wall of the box body 1, a guide pin 9 is fixed on the movable sealing plate 7, and a guide slot matching the guide pin 9 is provided on the side wall of the box body 1. Through the matching of the guide pin 9 and the guide slot, the movable sealing plate 7 can slide on the set track, and at the same time, the inner side of the movable sealing plate 7 can also slide against the outer side of the box body 1.

[0028] This embodiment further provides an automatic switching structure of the movable sealing plate 7, wherein the movable sealing plate 7 is controlled by a thermistor, and the thermistor includes a thermosensitive controller 10 and a lock tongue 11. The movable sealing plate 7 is provided with a lock hole 12 that cooperates with the lock tongue 11. When the lock tongue 11 cooperates with the lock hole 12 to lock, the movable sealing plate 7 is located in the open position. After the lock tongue 11 retracts and disengages from the lock hole 12, the movable sealing plate 7 is driven by its gravity to slide down to the closed position. When a fire occurs, the temperature inside the box 1 rises abnormally, the thermosensitive controller 10 controls the thermistor to start, and the thermistor drives the lock tongue 11 to retract, thereby disengaging from the lock hole 12, and the movable sealing plate 7 is automatically unlocked and slides down to the closed position.

[0029] The box 1 is provided with a fire alarm host 13, which is connected to a buzzer and a remote communication network. When a fire occurs, a high-decibel warning sound is emitted to remind people to evacuate, notify relevant personnel to go to emergency treatment, and send a fire alarm to the background through the communication network, so as to facilitate remote assistance in extinguishing the fire.

[0030] In the above-mentioned fireproof charging pile for new energy vehicles, the inner wall of the box body 1 is sprayed with a high-temperature resistant fireproof coating 14, which can effectively prevent the fire from spreading outward.

[0031] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
