A fire extinguishing mechanism 7 is provided on the rear side of the charging pile to monitor and extinguish fire inside the charging pile.

[0030] The ventilation mechanism 5 also includes a ventilation pipe 501, an exhaust fan 503, a connecting channel 504 and a ventilation grille 507. The ventilation pipe 501 with multiple circular holes 502 evenly spaced are symmetrically provided on the front and rear side walls inside the charging pile shell 2. An exhaust fan 503 that blows air from bottom to top is provided at the lower inner part of the ventilation pipe 501 by bolt connection. A connecting channel 504 that penetrates the charging pile shell 2 horizontally from outside to inside is provided at the lower part of the charging pile shell 2. The connecting channel 504 is connected to the ventilation pipe 501. A card slot is provided at the lower part of the ventilation port 4 of the charging pile shell 2. A ventilation grille 507 is provided at the edge of the ventilation port 4 of the charging pile shell 2 in a card-connected manner.

[0031] The cooling and fire prevention mechanism 6 also includes an electric push rod 505, a T-shaped baffle 506, a carbon dioxide gas cylinder 601, a rotating plate 602, a connecting block 603, a torsion spring 604 and a limit rod 606. The electric push rod 505 is arranged below the two air inlets of the lower part of the charging pile housing 2 near the connecting channel 504. A vertical slide 605 is opened at the lower part of the charging pile housing 2 just above the electric push rod 505. A T-shaped baffle 506 is slidably arranged in the slide 605. The T-shaped baffle 506 is connected to the telescopic rod of the electric push rod 505. A position directly below the two ventilation pipes 501 and inside the charging pile housing 2 is provided. There is a carbon dioxide gas cylinder 601 with an electric gas valve, the exhaust port 902 of the carbon dioxide gas cylinder 601 is located in the connecting channel 504, the ventilation holes of the ventilation grille plate are rotatably provided with a rotating plate 602, both ends of the rotating plate 602 are provided with connecting blocks 603, and torsion springs 604 are connected between the two ends of the rotating plate 602 and the ventilation grille plate. A vertical slide 605 is opened on the charging pile housing 2 near the horizontal sides of the ventilation grille plate, and a limit rod 606 is provided in the slide 605. A plurality of square holes are evenly spaced on the limit rod 606, and the connecting block 603 is in contact with the square holes of the limit rod 606.

[0032] The fire extinguishing mechanism 7 also includes a protective shell 701, an electric-controlled fire extinguisher 702, a three-head bifurcated pipe 703, a nozzle 704 and a smoke alarm 705. A protective shell 701 is provided on the rear side of the charging pile shell 2. Two electric-controlled fire extinguishers 702 are provided inside the protective shell 701 by means of a snap-on connection. The nozzle 704 of the electric-controlled fire extinguisher 702 is connected to the three-head bifurcated pipe 703. The ports of the three-head bifurcated pipe 703 away from the electric-controlled fire extinguisher 702 are all connected to the nozzles 704 and penetrate the charging pile shell 2 into the inner side thereof. A smoke alarm 705 is provided on the top of the inner side of the charging pile shell 2.

[0033] When the charging pile is started, the exhaust fan 503 in the charging pile shell 2 is started, and the cold air in the connecting hole 504 is blown into the charging pile, and the hot air inside the charging pile is discharged from the vent 4 through the ventilation grille, thereby cooling the inside of the charging pile. When the charging pile is overheated, the controller of the charging pile controls the electric push rod 505 to push the T-shaped baffle 506 upward to block the connecting hole 504, and then the electric valve of carbon dioxide is opened, and the low-temperature carbon dioxide gas is blown into the charging pile by the exhaust fan to cool the internal components of the charging pile, and when the T-shaped baffle 506 moves upward, the T-shaped baffle 506 will push the limit rod 606 upward, and when the limit rod 606 moves upward, it pushes upward through the square hole on the limit rod 606 Move the connecting block 603, and the connecting block 603 then rotates upward with the rotating plate 602 in the ventilating holes of the ventilation grille plate, blocking most of the ventilating holes of the ventilation grille plate, so that the air intake volume remains unchanged and the outside air is prevented from entering the charging pile by reducing the exhaust volume, so that the carbon dioxide gas fills the interior of the charging pile. When the internal components of the charging pile cannot be suppressed from overheating, the internal components of the charging pile are prevented from burning. Moreover, when the combustion of the internal components of the charging pile is suppressed, a large amount of smoke will be generated, and the smoke alarm 705 inside the charging pile will be triggered when it detects a certain amount of smoke. The controller of the charging pile starts the fire extinguisher tank and then extinguishes the internal components of the charging pile through the three-head branch pipe 703 nozzle 704 to prevent the problem from being out of control.

[0034] Example 2

[0035] like Figures 8 to 10As shown, on the basis of Example 1, it specifically includes a fixed ejection mechanism 8, which specifically includes a mounting groove 801, a first fixing column 802, a top block 803, a first elastic member 804, a limiting plate 805, a fixing seat 806 and a second elastic member 807. The middle part of the charging pile housing 2 and the position above the vents 4 on both sides are provided with mounting grooves 801, two first fixing columns 802 are horizontally arranged in the mounting groove 801, and a top block 803 is slidably arranged between the two first fixing columns 802 on the same side of the charging pile. The top block 803 is The top block 803 slides in the installation groove 801, and the side away from the charging pile is an inclined surface. The first fixed column 802 is sleeved with a first elastic member 804, and the two ends of the first elastic member 804 are respectively connected to the installation groove 801 and the top block 803. A limit plate 805 sliding in the vertical direction is provided in the installation groove 801, and a limit hole is opened in the middle of the limit plate 805. A fixing seat 806 is provided on the top of the vent 4 of the charging pile housing 2, and the fixing seat 806 is in contact with the ventilation grille, and a second elastic member 807 is provided between the fixing seat 806 and the ventilation grille.

[0036] When installing the ventilation grille plate, the lower part of the ventilation grille plate is stuck in the slot of the vent 4 and the upper part of the ventilation grille plate is squeezed inside the charging pile, so that the ventilation grille plate compresses the first elasticity and contacts the fixing seat 806, and then the limiting plate 805 passes through the installation slot 801 to limit the ventilation grille plate. When a fire occurs in the charging pile and the fire extinguishing mechanism 7 cannot suppress the fire, the staff can move the top block 803 away from the charging pile and compress the second elastic member 807. As the top block 803 moves, the top block 803 lifts the limiting plate 805 through the limiting hole of the limiting plate 805. When the limiting plate 805 is out of contact with the ventilation grille plate, the upper part of the ventilation grille plate is pushed open to the position of the charging pile vent 4 under the action of the first elastic member 804 resetting. The staff can then directly remove the ventilation grille plate, and then use a fire extinguisher directly from the outside of the device to extinguish the internal components of the charging pile, so as to facilitate the staff to better extinguish the fire of the charging pile.

[0037] like Figure 4 As shown, on the basis of Example 1, a limited pressure mechanism 9 is specifically included, which specifically includes an extension tube 901, a second fixed column 903, a sealing plate 904 and a third elastic member 905. Two extension tubes 901 are provided at the lower part of the ventilation grille. The extension tubes 901 penetrate the ventilation grille. The extension tube 901 is located at the lower part of the side of the ventilation grille away from the charging pile and has an exhaust port 902. A second fixed column 903 is horizontally provided inside the extension tube 901, and a sealing plate 904 is slidably provided on the second fixed column 903. The sealing plate 904 is in sliding contact with the inside of the extension tube 901, and a third elastic member 905 is connected between the sealing plate 904 and the extension tube 901.

[0038] When the carbon dioxide gas cylinder 601 is inflated into the interior of the charging pile and the air pressure inside the charging pile is too high, the sealing plate 904 is moved away from the interior of the charging pile under the action of the air pressure. During this process, the third elastic member 905 is compressed, and when the sealing plate 904 moves over the exhaust port 902, excess gas will be discharged outward from the exhaust port 902, and as the air pressure changes, the position to which the sealing plate 904 is squeezed is different, and the size of the exhaust buckle that actually exhausts the air outward is also different. This avoids the fire extinguishing mechanism 7 from being unable to operate normally due to the air holes of the ventilation grille plate being restricted from exhausting air, resulting in excessive air pressure in the charging pile.

[0039] like Fig.11 As shown, based on the embodiment 1, it further includes a placement box 10 and a dry powder fire extinguisher 11. The placement box 10 is provided on the upper part of the protective shell 701, and the dry powder fire extinguisher 11 is placed in the placement box 10.

[0040] The staff can place the dry powder fire extinguisher 11 in the placement box 10 to prevent the fire extinguisher 11 from being accidentally bumped by people when placed outside. At the same time, it can effectively prevent the dry powder fire extinguisher 11 from moisture and corrosion, and in the event of an accident, it is convenient for the staff to quickly get the dry powder fire extinguisher 11 for use.

[0041] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
