[0040] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0041] A self-protection outdoor V2G charging pile includes a housing 1 for installing electronic components, wherein a plurality of installation compartments 2 are arranged in an upper and lower distribution inside the housing 1, and adjacent installation compartments 2 are separated by an insulating plate 21, and the electronic components are respectively arranged in the plurality of installation compartments 2;

[0042] The housing 1 is provided with first cooling fans 11 matching the number of the installation grids 2. The first cooling fans 11 are arranged through the housing 1, with their leeward openings facing the installation grids 2 and their air outlets facing the outside of the housing 1. A smoke alarm 111 is also arranged on the side facing the installation grids 2.

[0043] A mounting seat 12 is also provided on the inner wall of the shell 1 at the position of the first cooling fan 11. A through groove 121 connected to the interior of the mounting seat 12 is provided on the side of the mounting seat 12 facing the mounting grid 2. An inflatable dry powder bag 122 is provided in the mounting seat 12, and the inflatable dry powder bag 122 is abutted against the first cooling fan 11 and the through groove 121 at the same time.

[0044] Furthermore, an insulating plate 21 is provided at the top and bottom of each installation grid 2 , and an isolation device 3 for disconnecting the electrical connection is provided between the two insulating plates 21 between two adjacent installation grids 2 .

[0045] Furthermore, the isolation device 3 includes two fixed seats 31, and two rows of wiring seats 311 distributed up and down are arranged in the fixed seats 31. The wiring ports of the two rows of wiring seats 311 are respectively located in two adjacent installation grids 2. A first spring 312 is arranged between each wiring seat 311 and the fixed seat 31. When all the first springs 312 are in a normal state, the two rows of wiring seats 311 are separated from each other.

[0046] Furthermore, two guide rods 32 fixed to the inner wall of the shell 1 are arranged between the two fixed seats 31, and a movable plate 33 that can move along the setting direction of the guide rods 32 is connected to the guide rods 32. A plurality of threaded holes 331 are arranged on both sides of the movable plate 33, and a plurality of screws are arranged on the threaded holes 331. The ends of the screws are fixed on a pressure plate in contact with the terminal seat 311, and the upper and lower rows of terminal seats 311 are clamped by the pressure plate and the fixed seat 31 to maintain a contact state.

[0047] Furthermore, a metal plate 34 is provided on the end of the guide rod 32 facing away from the shell 1, and a first electromagnet 332 that can be adsorbed on the metal plate 34 is provided in the middle of the movable plate 33. The first electromagnet 332 is connected to the inner wall of the shell 1 through the second spring 333. When the first electromagnet 332 and the metal plate 34 are separated from each other, the second spring 333 is in a normal state, the pressure plate and the terminal block 311 are separated from each other, the first spring 312 is in a normal state, and the upper and lower rows of terminal blocks 311 are separated from each other.

[0048] In a specific embodiment, Figures 1 to 16 As shown, the main body of a self-protection outdoor V2G charging pile proposed in the present application is a shell 1, and there are three installation grids 2 inside the shell 1, and the three installation grids 2 are arranged in an upper and lower distribution. An insulating plate 21 is arranged at the top and bottom of each installation grid 2, and the insulating plate 21 is used to separate the adjacent installation grids 2. The electronic components are respectively arranged in the three installation grids 2, realizing a modular layout, which can effectively prevent potential interference between electronic components.

[0049] In addition, each installation grid 2 is also equipped with a first cooling fan 11, and these three first cooling fans 11 are all set through the shell 1 to ensure efficient heat exchange. Among them, the leeward port of the first cooling fan 11 directly faces the internal area of ​​the installation grid 2 to effectively extract the internal accumulated heat, while its air outlet faces the outside of the shell 1, which can quickly discharge the heat to the external environment. In addition, to improve safety, a smoke alarm 111 is also integrated on the edge of the fan facing the side of the installation grid 2. The smoke alarm 111 can detect smoke at the early stage of a fire and trigger an alarm signal. Once the smoke alarm 111 is triggered, a self-protection outdoor V2G charging pile proposed in this application will quickly cut off the power supply to prevent the spread of fire and ensure the safety of surrounding facilities and personnel.

[0050] A mounting seat 12 is also provided on the side of the first cooling fan 11 facing the installation grid 2. The mounting seat 12 is located on the inner wall of the housing 1, and not only stably supports the first cooling fan 11, but also has a through slot 121 on the side of the mounting seat 12 facing the installation grid 2, and the through slot 121 is connected to the inner space of the mounting seat 12. The mounting seat 12 is in the shape of a ring, and an inflatable dry powder bag 122 is also provided in the mounting seat 12. When the first cooling fan 11 is connected to the mounting seat 12, one side of the inflatable dry powder bag 122 abuts against the first cooling fan 11, and the other side abuts against the through slot 121. Since the inflatable dry powder bag 122 is a plastic film wrapped with dry powder, after the first cooling fan 11 is installed, a pressure is generated on the inflatable dry powder bag 122 toward the installation grid 2, so that the plastic film on the surface of the inflatable dry powder bag 122 is exposed in the installation grid 2 through the through slot 121.

[0051] When a fire occurs in a certain installation compartment 2, since the plastic film on the surface of the inflatable dry powder bag 122 is exposed in the installation compartment 2, it will rupture under the high temperature of the flame, so that the dry powder stored inside it can be sprayed to the fire source area, thereby achieving precise fire extinguishing. And because the installation compartment 2 adopts a modular design, the inflatable dry powder bag 122 in each installation compartment 2 is independently configured. Therefore, when a fire occurs in a certain installation compartment 2, only the dry powder bag in the installation compartment 2 will be activated and release dry powder, effectively avoiding unnecessary spread of dry powder and reducing potential damage to undamaged electronic components. And because the smoke alarm 111 will be triggered when a fire occurs, the self-protection outdoor V2G charging pile proposed in this application will be powered off, and the first cooling fan 11 will also stop working, so that no airflow will be generated to interfere with the spread of dry powder, ensuring the fire extinguishing effect.

[0052] In addition, an isolation device 3 is also provided between two adjacent installation grids 2. Since an insulating plate 21 is provided at the top and bottom of each installation grid 2, specifically, taking the upper and lower installation grids 2 as an example, an isolation device 3 is provided between the insulating plate 21 at the bottom of the upper installation grid 2 and the insulating plate 21 at the top of the lower installation grid 2. The isolation device 3 includes two fixed seats 31 provided on the left and right, and two rows of wiring seats 311 are provided in the fixed seats 31. The two rows of wiring seats 311 are provided symmetrically from top to bottom. The wiring port of the upper wiring seat 311 is located at the bottom of the upper installation grid 2, and the wiring port of the lower wiring seat 311 is located at the top of the lower installation grid 2. The electronic components in the upper and lower adjacent installation grids 2 are connected to the wiring ports of the wiring seats 311 through wires. When the upper and lower rows of wiring seats 311 abut against each other, the electronic components in the two installation grids 2 are connected to establish electrical connection. A first spring 312 is disposed between each wiring seat 311 and the fixing seat 31. When all the first springs 312 are in a normal state, the upper and lower rows of wiring seats 311 are separated from each other and do not contact each other.

[0053] Two guide rods 32 are arranged between the two fixed seats 31, and the two guide rods 32 are fixed on the inner wall of the housing 1. The movable plate 33 is connected to the guide rods 32 and can move forward and backward along the setting direction of the guide rods 32. The guide plate provides support and guidance for the movable plate 33. In addition, multiple threaded holes 331 are arranged on both sides of the movable plate 33, and multiple screws are installed on the threaded holes 331. A pressing plate is fixedly connected to the end of each screw, and these pressing plates are designed to be in a shape that can be in close contact with the wiring seat 311. Since the screw can be tightened or loosened as needed, the pressing plate can move toward the wiring seat 311 or move away from the wiring seat 311. When the screw is tightened, the pressing plate will move toward the wiring seat 311 and cooperate with the fixed seat 31 to form a stable clamping structure. When wiring, the upper and lower rows of wiring seats 311 are manually abutted against each other, and then the upper and lower rows of wiring seats 311 are clamped by tightening the screws, so that all the first springs 312 remain in a stretched state. In this clamping structure, the upper and lower rows of wiring sockets 311 are clamped between the pressing plate and the fixing seat 31. Since the pressing plate can fit tightly on the wiring sockets 311, the upper and lower rows of wiring sockets 311 can maintain a stable contact state, thereby ensuring that the electronic components in the two adjacent installation grids 2 can be stably electrically connected, providing a strong guarantee for the overall stable operation.

[0054] A metal plate 34 is arranged at one end of the two guide rods 32 facing away from the housing 1, and a first electromagnet 332 which can be adsorbed on the metal plate 34 is arranged in the middle position of the movable plate 33, and the first electromagnet 332 is connected to the inner wall of the housing 1 through the second spring 333. When it is necessary to keep the upper and lower rows of wiring seats 311 in contact, the first electromagnet 332 is energized to generate magnetic force and drive the movable plate 33 to be adsorbed on the metal plate 34, and the second spring 333 is in a stretched state. Since the movable plate 33 is connected to the pressing plate by screws, the pressing plate will also apply pressure to the wiring seat 311. When the pressing plate is tightly fitted on the wiring seat 311, the upper and lower rows of wiring seats 311 are clamped between the pressing plate and the fixed seat 31, thereby maintaining a stable contact state. When a fire occurs, the first electromagnet 332 loses power supply, and the movable plate 33 is separated from the metal plate 34 by the rebound force of the second spring 333, and the second spring 333 returns to a normal state. At this time, the pressing plate and the wiring seat 311 are also separated from each other, and since the wiring seat 311 is not clamped by the pressing plate and the fixing seat 31, the first spring 312 is also in a normal state. In this state, the upper and lower rows of wiring seats 311 are also separated from each other and have no contact. Through this design, when a fire occurs in a certain installation grid 2, the adjacent installation grid 2 will be disconnected from the burning installation grid 2 to prevent the fire from spreading to the electronic components in other installation grids 2 through the connected wires, thereby avoiding damage to other undamaged electronic components.

[0055] Furthermore, two second cooling fans 13 are arranged on the top of the inner wall of the housing 1 , and air guide plates 22 are arranged on both sides of the installation grid 2 .

[0056] Furthermore, the air guide plate 22 is provided with a plurality of through holes for gas to enter and exit, and a fireproof plate 14 is also arranged between the air guide plate 22 and the inner wall of the shell 1. A slide groove 141 is arranged obliquely at the connection between the fireproof plate 14 and the air guide plate 22. The fireproof plate 14 can move along the slide groove 141 to a position in which it fits with the air guide plate 22, and a plurality of stop blocks matching the number of through holes are arranged on the fireproof plate 14. When the air guide plate 22 fits with the fireproof plate 14, the stop blocks are embedded in the through holes.

[0057] Furthermore, a second electromagnet 15 is arranged between the inner wall of the shell 1 and the air guide plate 22, and the slide groove 141 is inclined from high to low in the direction of the second electromagnet 15. A support rod is arranged below the second electromagnet 15, and an L-shaped plate 151 that can be adsorbed on the second electromagnet 15 is movably arranged on the support rod. The L-shaped plate 151 moves on the support rod and abuts against or separates from the fireproof plate 14. When the L-shaped plate 151 abuts against the fireproof plate 14, the fireproof plate 14 and the air guide plate 22 are separated from each other.

[0058] In a specific embodiment, Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, two second cooling fans 13 are arranged at the top of the inner wall of the housing 1, and air guide plates 22 with multiple through holes are arranged on both sides of the installation grid 2. There is also a gap between the air guide plate 22 and the inner wall of the housing 1 for air flow to pass through. This design enables the second cooling fan 13 at the top to work together with the first cooling fan 11 on the side of the housing 1. The airflow blown from the top passes through the air guide plate 22 into the installation grid 2 and then is discharged from the housing 1 together with the heat by the first cooling fan 11, thereby improving the heat dissipation effect, effectively controlling the internal temperature of the charging pile, and reducing the risk of fire caused by high temperature. In addition, openings for taking out the charging gun are arranged on both sides of the housing 1. The charging gun is embedded in the housing 1 and is located below the second cooling fan 13. While avoiding direct exposure to the outside world, it can also quickly dissipate heat through the airflow blown out by the second cooling fan 13 after use.

[0059] A fireproof plate 14 is also provided between the inner wall of the housing 1 and the air guide plate 22. A fireproof plate 14 is provided on both sides of each installation grid 2. An inclined slide 141 is provided at the connection between the fireproof plate 14 and the air guide plate 22. The fireproof plate 14 can move along the slide 141 to a position where it fits with the air guide plate 22. When the fireproof plate 14 fits with the air guide plate 22, the stopper on the fireproof plate 14 is embedded in the through hole of the air guide plate 22 to achieve a sealing effect. A second electromagnet 15 is also provided between the inner wall of the housing 1 and the air guide plate 22 on both sides of each installation grid 2. The slide 141 is inclined from high to low toward the direction of the second electromagnet 15. An L-shaped plate 151 is movably mounted on the support rod below the second electromagnet 15. The L-shaped plate 151 is magnetic and can move on the support rod in response to the attraction of the second electromagnet 15, thereby contacting or separating from the fireproof board 14. When the L-shaped plate 151 contacts the fireproof board 14, it plays a supporting and limiting role for the fireproof board 14, so that the fireproof board 14 is located at the height of the slide groove 141, so that the fireproof board 14 is separated from the air guide plate 22. When a certain installation grid 2 catches fire, the second electromagnet 15 loses power supply, and the L-shaped plate 151 is not attracted by the magnetic force and falls to the bottom of the support rod. At this time, the L-shaped plate no longer abuts against the fireproof board 14. The fireproof board 14 is affected by the inclination angle of the slide groove 141 and slides to a position that fits the air guide plate 22. The stopper on the fireproof board 14 is embedded in the through hole on the air guide plate 22, so as to seal each installation grid 2 and prevent the fire from spreading to the installation grid 2 that has not caught fire.

[0060] Furthermore, a base 4 is provided below the shell 1 , a lead screw and a motor are provided inside the base 4 , a nut connected to the lead screw is provided at the bottom of the shell 1 , and the motor drives the lead screw and the nut to make the shell 1 descend into the base 4 .

[0061] Furthermore, a movable groove 41 is vertically provided on the side of the base 4, a detection plate 411 is provided in the movable groove 41, a connecting rod 412 is provided below the detection plate 411, a buoyancy ball 413 is provided on the connecting rod 412, and the buoyancy ball 413 can move along the connecting rod 412. When the buoyancy ball 413 contacts the detection plate 411, the motor starts and the shell 1 descends to the inside of the base 4.

[0062] In a specific embodiment, Figures 14 to 16As shown, a hollow base 4 is also provided below the housing 1, and a screw and a motor for driving the screw are provided inside the base 4. The bottom of the housing 1 is designed with a nut structure matching the screw. Through the meshing of the nut and the screw, the motor can drive the housing 1 to move vertically along the direction of the screw, so as to realize the stable descent of the housing 1 to the inside of the base 4. Most of the base 4 is located below the ground. In the part of the base 4 located on the surface, a movable groove 41 is vertically provided on its side, and a detection plate 411 is provided in the movable groove 41. A connecting rod 412 is provided below the detection plate 411, and a buoyancy ball 413 is provided on the connecting rod 412. The buoyancy ball 413 can slide freely on the connecting rod 412 and move up and down according to the buoyancy change of the liquid environment in which the buoyancy ball 413 is located. When the buoyancy ball 413 rises to contact with the detection plate 411 due to the buoyancy, the motor in the base 4 is started, and the housing 1 is driven to descend to the inside of the base 4 through the interaction between the driving screw and the nut. A rubber cover is provided at the top of the shell 1, and a rubber ring is embedded on the inner side of the top of the shell 1. When the shell 1 is lowered into the base 4, the rubber cover blocks the top of the shell 1, and the rubber ring fills the gap between the shell 1 and the base 4, thereby achieving a sealing function and ensuring waterproof performance. Specifically, in the event of extreme climatic conditions such as floods and typhoons, when the buoyancy ball 413 is affected by the buoyancy of the water surface and touches the preset detection plate 411 in the movable groove 41, it indicates that the water level is already high, which is very likely to pose a potential threat to a self-protection outdoor V2G charging pile proposed in this application. To cope with this situation, the entire shell 1 can be driven by a motor to drive the screw rod and nut to descend to the inside of the base 4 located under the ground. This design not only significantly reduces the risk of the charging pile being flooded, but also achieves waterproof protection through physical isolation.

[0063] 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 and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
