Most of the charging piles installed in parking lots are also outdoors. In the hot summer, the air temperature and surface temperature rise, and the temperature inside the charging pile will also rise accordingly. In addition, the electronic components inside the charging pile will also generate a certain amount of heat during operation.

[0013] Preferably, the slide bar contacts the lower surface of the inclined plate of the guide plate, and the impact pad is made of soft rubber material.

[0014] Preferably, coolant circulates inside the water pump, the water cooling pipe and the water guide groove.

[0015] As described above, the beneficial effects of the automobile charging pile with fire-fighting function in the present invention are as follows: The heat from the high-temperature components inside the charging cabinet body is transferred to the coolant in the water-cooling pipe. The flowing coolant can continuously absorb the heat and maintain the temperature inside the charging cabinet body within a suitable range, effectively avoiding the performance degradation or aging of the equipment due to overheating. In addition, it can also stabilize the performance of the electronic components inside the charging pile, so that the charging efficiency and voltage output of the entire charging cabinet body remain stable, avoiding safety accidents such as line short circuits and fires caused by aging components. The slowly rotating fan blades can disturb part of the heat inside the charging cabinet body to the outside, so that the heat inside the charging cabinet body will be discharged from the vents to the outside of the charging cabinet body, further avoiding the situation where the temperature inside the charging cabinet body is too high. In addition, because the direction of the disturbed airflow around the fan blades is toward the outside of the charging cabinet body, it can prevent excessive dust from falling into the interior of the charging cabinet body from the vents, thereby preventing the dust from causing a short circuit to the operation of the electronic components inside the charging cabinet body, and further improving the operating stability of the electronic components inside the charging cabinet body. By spraying dry powder fire extinguishing agent from a fire extinguisher, the flame of a short circuit fire inside the charging cabinet body can be extinguished to prevent the flame from spreading and smoke from being generated, thus preventing the flame from damaging other electronic components and circuits, reducing the risk of people around the charging cabinet body inhaling harmful smoke, and preventing other chain reactions caused by short circuit fire, such as burning other charging piles and vehicles being charged after the fire spreads, thus ensuring the reliable operation of the charging facilities; By controlling the increase of the power of the water pump, the suction efficiency of the water pump is improved, and the coolant sucked by the pump will circulate faster in the water pump, water cooling pipe and water guide groove. After the coolant flow rate increases, according to the heat exchange principle, the heat exchange rate is related to the flow rate of the fluid. The higher the flow rate, the more heat can be taken away per unit time. The coolant can more quickly take away the high heat inside the charging cabinet body in time, further avoiding the high temperature caused by the fire affecting other electronic components that have not caught fire; The rapidly rotating fan blades disturb the air flow, and the high-temperature air inside the charging cabinet body can be quickly discharged outward through the vents. By quickly discharging the air outward, the air inside the charging cabinet body can be further reduced. Although the air cannot be completely emptied, it can indirectly retard the flame after the fire. The flame burns slower in a low-oxygen environment, thereby avoiding the rapid spread of the fire after the fire. The connecting rod drives the plug to move upward inside the retraction chamber and compresses spring 1. After the plug moves upward, it is no longer connected to the socket, thereby cutting off the power to the electronic components inside the entire charging cabinet body. At this time, the control panel can also be connected to the backup battery in the charging cabinet body, so that the water pump continues to pump coolant. By disconnecting the charging cabinet body from the external cable, continuous fire after a short circuit can be avoided. In addition, the resistance in the circuit is prevented from being reduced after a short circuit, which causes the charging pile to draw excessive current from the power grid, and the normal operation of other equipment on the same circuit can be avoided.

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] An embodiment provided by the present invention will be described in detail below: like Figures 1 to 7 As shown, a car charging pile with fire protection function includes a charging cabinet body 1, a bottom box 2 is fixedly connected to the bottom of the charging cabinet body 1, a base 3 is fixedly connected to the bottom of the bottom box 2, charging cables 4 are arranged on both sides of the charging cabinet body 1, ventilation holes 5 are opened on both sides of the charging cabinet body 1, a control panel 6 is fixedly connected to the outer surface of the charging cabinet body 1, and a cooling component for cooling the inside of the charging cabinet body 1 is arranged on the charging cabinet body 1; The cooling component includes a water pump 71 fixedly connected to the top of the charging cabinet body 1.

One end of the rotating shaft 74 passes through the transmission shell 73 to the outside of the transmission shell 73. One end of the rotating shaft 74 passing through the transmission shell 73 is fixedly connected to a plurality of fan blades 77 arranged in a ring array, and the positions of the fan blades 77 correspond to the vent 5. When the fan blades 77 rotate, the wind direction generated is toward the outside of the vent 5, that is, the air in the charging cabinet body 1 is discharged outward.

[0020] like Figure 2 , Figure 7 and Figure 8As shown, a fire extinguisher 8 is fixedly connected to the top of the charging cabinet body 1. The fire extinguisher 8 and the water pump 71 are both controlled by the control panel 6. A temperature sensor is provided inside the charging cabinet body 1 for detecting the temperature change of the charging cabinet body 1. A backup battery is provided inside the charging cabinet body 1. The backup battery is provided at the top of the inner cavity of the charging cabinet body 1 for supplying power to the fire extinguisher 8 and the water pump 71 after power failure.

[0021] like Figures 9 to 11 As shown, a power-off component for disconnecting the line is provided at the bottom of the charging cabinet body 1, and the power-off component includes a retraction chamber 91 opened at the bottom of the charging cabinet body 1, and a spring 92 is fixedly connected to the inside of the retraction chamber 91, and a plug 93 is fixedly connected to the bottom of the spring 92, and the plug 93 slides inside the retraction chamber 91, and a spirally wound cable is connected between the plug 93 and the charging cabinet body 1, which is used to compress the cable after the plug 93 moves upward, and a socket 94 corresponding to the position of the plug 93 is fixedly connected to the bottom of the bottom box 2, and the plug 93 and the socket 94 are plugged into each other, and the socket 94 is connected to an external cable.

[0022] like Figures 9 to 11 As shown, the power-off assembly also includes a connecting rod 95 fixedly connected to the outer surface of the plug 93, and the end of the connecting rod 95 away from the socket 94 is fixedly connected to a guide plate 96, which is composed of a horizontal plate and an inclined plate. A notch is provided on the top of the bottom box 2 to provide movement space for the guide plate 96 when it moves upward. A water guide groove 97 is provided at the bottom of the charging cabinet body 1, and the water guide groove 97 is set in a U shape. The two ends of the water guide groove 97 are respectively connected to the bottom of the two water-cooling pipes 72. An active cavity 98 is provided at the bottom of the charging cabinet body 1, and the top of the active cavity 98 is connected to the water guide groove 97, and the bottom of the active cavity 98 is connected to the notch of the bottom box 2. The active cavity 98 is set in a T shape, and the inner wall of the cavity top of the active cavity 98 is fixed. A spring 2 99 is fixedly connected, and a movable rod 910 is fixedly connected to one end of the spring 2 99 away from the movable cavity 98. The movable rod 910 slides inside the movable cavity 98. The movable rod 910 is fixedly connected to one end passing through the notch of the bottom box 2 with a sliding rod 914. The sliding rod 914 contacts the lower surface of the inclined plate of the guide plate 96. A sealing strip 911 is fixedly connected to the top of the movable rod 910. The sealing strip 911 is used to block the connection between the movable cavity 98 and the water guide groove 97. An impact ring 912 is fixedly connected to the top of the sealing strip 911. The impact ring 912 slides inside the water guide groove 97. A plurality of impact pads 913 arranged in a ring array are fixedly connected to the middle of the impact ring 912. The impact pads 913 are set to be made of soft rubber material.

[0023] The cooling liquid circulates in the water pump 71, the water cooling pipe 72 and the water guide groove 97, and the flow direction is from right to left. Fig.10 Flows from the right to the left.

[0024] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments: The initial state is: The spring 2 99 is not compressed by the movable rod 910. At this time, the movable rod 910 is on the right side of the movable cavity 98. Fig.11 On the right side, the movable rod 910 does not cause the slide rod 914 to push the guide plate 96. At this time, the connecting rod 95 is in the lowest position, and then the plug 93 is in the lowest position and plugged into the socket 94. At this time, the spring 1 92 is not compressed by the plug 93.

[0025] The working status is: The temperature sensor detects the temperature inside the charging cabinet body 1. When the temperature inside the charging cabinet body 1 rises, the temperature sensor controls the water pump 71 to be energized through the control panel 6. After the water pump 71 is energized, the coolant inside the water cooling tube 72 is pumped, so that the coolant circulates and flows slowly in the water pump 71, the water cooling tube 72 and the water guide groove 97. At this time, the water pump 71 is in a low-power state, which can ensure that energy is not used too much during operation. Based on the basic law of heat conduction, that is, heat is always transferred from a high-temperature object to a low-temperature object, the heat of the high-temperature components inside the charging cabinet body 1 will be transferred to the coolant in the water cooling tube 72. The flowing coolant can continuously absorb heat and maintain the internal temperature of the charging cabinet body 1 within an appropriate range, effectively avoiding equipment performance degradation or aging due to overheating. In addition, it can also stabilize the performance of the electronic components inside the charging pile, so that the charging efficiency and voltage output of the entire charging cabinet body 1 remain stable, reducing the possibility of short circuit fire due to aging.

[0026] In addition, during the slow flow of the coolant inside the water-cooling tube 72, the flow of the coolant will push the wave plate 76 located inside the transmission shell 73, causing the wave plate 76 to rotate in the direction of the coolant flow, and the wave plate 76 drives the rotating shaft 74 to rotate through the impeller 75, and the rotating shaft 74 will drive the fan blades 77 to rotate. Because the flow rate of the coolant is slow, the rotation of the fan blades 77 is also slow at this time, but it can also disturb part of the heat inside the charging cabinet body 1 to the outside, so that the heat inside the charging cabinet body 1 will be discharged from the vent 5 to the outside of the charging cabinet body 1, further avoiding the situation where the temperature inside the charging cabinet body 1 is too high, and because the direction of the fan blades 77 disturbing the airflow is toward the outside of the charging cabinet body 1, it can prevent too much dust from falling into the interior of the charging cabinet body 1 from the vent 5, thereby preventing the dust from causing a short circuit effect on the operation of the electronic components inside the charging cabinet body 1, and further improving the operation stability of the electronic components inside the charging cabinet body 1.

[0027] It should be noted that: since the flow rate of the coolant is slow, the rotation speed of the fan blade 77 is also slow. At this time, although the fan blade 77 can blow the gas to the outside of the charging cabinet body 1, some gas will still enter the inside of the charging cabinet 1 from the vent 5 to ensure that the air pressure inside and outside the charging cabinet body 1 remains balanced. At the same time, the flow speed of the coolant inside the water guide groove 97 is also slow. The coolant with a slower flow rate cannot drive the impact pad 913 located inside the water guide groove 97 to move.

[0028] Short circuit fire power-off components for protection: After a short circuit and fire occurs inside the charging cabinet body 1, the temperature inside the charging cabinet body 1 will rise abnormally. When the temperature sensor detects that the temperature inside the charging cabinet body 1 is abnormally high, the control panel 6 controls the water pump 71 to increase its power, thereby improving the suction efficiency of the water pump 71. The pumped coolant will circulate faster inside the water pump 71, the water cooling pipe 72 and the water guide groove 97. After the coolant flow rate increases, according to the heat exchange principle, the heat exchange rate is related to the flow rate of the fluid. The higher the flow rate, the more heat can be taken away per unit time. The coolant can more quickly take away the high heat inside the charging cabinet body 1 in time, further avoiding the high temperature generated by the fire affecting other electronic components that have not caught fire.

[0029] In addition, after the coolant flow rate increases, the coolant pushes the wave plate 76 to rotate faster, and then the wave plate 76 drives the rotating shaft 74 to rotate faster through the impeller 75, and the rotating shaft 74 drives the fan blades 77 to rotate faster. The rapidly rotating fan blades 77 also disturb the air flow faster, and then the high-temperature air inside the charging cabinet body 1 can be quickly discharged to the outside through the vents 5. By quickly discharging the air to the outside, the air inside the charging cabinet body 1 can be further emptied. Although the air cannot be completely emptied, it can also indirectly have a flame retardant effect on the flame after the fire. The flame burns slower under low oxygen conditions, thereby avoiding the rapid spread of the fire after the fire.

[0030] At the same time, as the flow rate of the coolant increases, according to the momentum theorem, the impulse of the resultant external force is equal to the increment of the momentum of the object. When the liquid flows, the liquid molecules have a certain momentum. When the flow rate of the coolant increases, the mass of the coolant that hits the object per unit time remains unchanged, but the speed increases, resulting in an increase in momentum. At this time, the coolant has enough momentum to push the impact pad 913 to move. Since the flow direction of the coolant inside the water guide groove 97 is Fig.10As shown, from right to left, the impact pad 913 drives the impact ring 912 to move to the left inside the water guide groove 97, and the impact ring 912 drives the sealing strip 911 to move to the left inside the active cavity 98. The sealing strip 911 will always block the connection between the water guide groove 97 and the active cavity 98 during the movement, which can prevent the coolant from flowing out from the connection between the water guide groove 97 and the active cavity 98. The sealing strip 911 will drive the active rod 910 to move to the left synchronously during the movement, and the active rod 910 will compress the spring 99. In addition, the active rod 910 will synchronously drive the sliding rod 914 to move to the left synchronously. The sliding rod 914 will push the inclined plate of the guide plate 96 during the movement, so that the guide plate 96 can be pressed. The inclined plate of plate 96 drives the connecting rod 95 to move upward through its cross plate, and the connecting rod 95 drives the plug 93 to move upward inside the retraction chamber 91 and compresses the spring 92. After the plug 93 moves upward, it is no longer connected with the socket 94, thereby cutting off the power to the electronic components inside the entire charging cabinet body 1. At this time, the control panel 6 can also be connected to the backup battery in the charging cabinet body 1, so that the water pump 71 continues to pump coolant. By disconnecting the charging cabinet body 1 from the external cable, continuous fire after a short circuit can be avoided. In addition, the resistance in the circuit is prevented from being reduced after a short circuit, which causes the charging pile to draw excessive current from the power grid, and the normal operation of other equipment on the same circuit can be avoided.

[0031] It should be noted that in the actual production of the present scheme, the structure of the plug 93 and the socket 94 will adopt a structure that is easy to move, and there is no self-locking device of the high-power connector in the prior art. When the plug 93 is connected to the socket 94, it mainly relies on its own gravity and the pressure provided by the spring 92 to engage with the socket 94. Therefore, when the movable rod 910 pushes the inclined surface of the guide plate 96 to lift the plug 93, the plug 93 will not be difficult to lift due to over-tightening or self-locking of the plug 93 and the socket 94. The materials of the impact ring 912 and the impact pad 913 are both hard materials. When the water flow speed inside the water guide groove 97 increases, the water pressure will also increase synchronously. The impact ring 912 can obtain sufficient thrust to drive the movable rod 911 and the guide plate 96. There is also no problem that simply increasing the water flow speed cannot provide sufficient thrust to lift the plug 93.

[0032] In addition, due to the abnormally high temperature after the fire inside the charging cabinet body 1, the temperature sensor will control the start of the fire extinguisher 8 through the control panel 6. After the fire extinguisher 8 is started, the fire extinguisher 8 sprays dry powder fire extinguishing agent, thereby being able to extinguish the flame of the short circuit fire inside the charging cabinet body 1, avoiding the spread of flames, and preventing the generation of smoke, preventing the flame from damaging other electronic components and circuits, reducing the risk of people around the charging cabinet body 1 inhaling harmful smoke, and preventing other chain reactions caused by short circuit fire, such as burning other charging piles and vehicles being charged after the fire spreads, thereby ensuring the reliable operation of the charging facilities.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
