Description

Technical Field

[0001] The present invention relates to the technical field of vehicle charging piles, and particularly to a highly adaptable leakage detection device for vehicle charging piles. Background Technique

[0002] With the popularization of electric vehicles, the construction of charging piles has become increasingly important. A charging pile is a device used to provide electrical energy for electric vehicles. However, existing highly adaptable vehicle charging piles still have certain defects during use. During the use process, the structure and function of traditional vehicle charging piles are relatively simple, and they are easily affected by humid environments when outdoors for a long time, resulting in faults in the charging lines and potential safety hazards.

[0003] To overcome the above defects, a new energy charging pile with leakage detection in the prior art one (a Chinese patent with publication number CN222591272U and publication date March 11, 2025) relates to the technical field of new energy charging piles, including a charging pile component and a winding component arranged on one side of the charging pile component. A charging gun component is arranged on one side of the winding component, and a drying component is arranged inside the charging pile component. The charging pile component includes a pile body. A through-hole groove is arranged on one side of the pile body, a protective plate is arranged on one side of the through-hole groove, and heat dissipation hole grooves are evenly distributed in the middle of the protective plate. The drying component includes a heating plate component fixedly installed in the inner cavity of the pile body. The heating plate component is provided with an installation cavity box. A second motor is arranged on one side of the installation cavity box, and a first lead screw is rotatably connected to the inner cavity of the installation cavity box. By means of the drying component, the problem that the existing new energy charging pile is affected by humid environments when outdoors for a long time and can be dried at any time to prevent the charging pile from easily malfunctioning is solved, improving the practicality of the device. In the prior art two (a Chinese patent with publication number CN221938048U and publication date November 1, 2024), a new energy charging pile with a leakage detection function relates to the technical field of charging piles, including a housing. A leakage detection mechanism is arranged on the right side of the housing. A charging pile main body is fixedly installed inside the housing. A heat dissipation component is arranged on the back of the inner wall of the housing. The leakage detection mechanism includes an installation bracket, an installation box, and a backing plate. A conductive iron nail penetrates and slides through the inside of the installation bracket. The setting of this leakage detection mechanism enables the new energy charging pile to detect whether the charging pile is leaking in a timely manner and issue an alarm to surrounding personnel to prevent uninformed people from getting an electric shock, increasing the safety performance of the device. The setting of this heat dissipation component enables the new energy charging pile to dissipate heat during operation, and uses a reciprocating structure to evenly dissipate heat from the charging pile, increasing the service life of the device, reducing the probability of the charging pile malfunctioning, and increasing the safety of the charging pile.

[0004] Although the prior art reduces the leakage probability of the charging pile by setting a drying component or a heat dissipation component, during the working process, a heating plate component or a cooling fan is used for treatment, resulting in relatively high overall energy consumption, increased overall maintenance costs, and a relatively large overall occupied space, which leads to an increase in the volume of the charging pile. Moreover, once the charging pile leaks electricity, it is likely to cause a fire, and it is difficult for the set drying component or heat dissipation component to handle the fire in time, resulting in the spread of the fire and serious property losses.

[0005] In view of the above problems, there is an urgent need to innovate and design on the basis of the original highly adaptable leakage detection device for vehicle charging piles. Therefore, we propose that the highly adaptable leakage detection device for vehicle charging piles can well solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a highly adaptable leakage detection device for vehicle charging piles to solve the problems in the above background technology, that is, in the current market, a heating plate component or a cooling fan is used for treatment, resulting in relatively high overall energy consumption, increased overall maintenance costs, a relatively large overall occupied space, which leads to an increase in the volume of the charging pile. Moreover, once the charging pile leaks electricity, it is likely to cause a fire, and it is difficult for the set drying component or heat dissipation component to handle the fire in time, resulting in the spread of the fire and serious property losses.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A highly adaptable leakage detection device for vehicle charging piles, including a set charging pile. Inside the charging pile, there is a charging socket for connecting a charging cable. A monitoring socket is installed at the side end of the charging socket. Inside the monitoring socket, there is a monitoring component for leakage detection. Inside the charging pile, there is a power-off switch for rapid power-off. An audible and visual alarm for warning is installed on the charging pile. The monitoring component, the power-off switch, and the audible and visual alarm are electrically connected. Inside the monitoring socket, a fire extinguishing component is connected through a conveying component. The conveying component includes a second shape memory metal sheet for deformation. After the second shape memory metal sheet deforms, the contact piece on its surface contacts the contact piece inside the monitoring socket to generate a leakage signal, and the signal is transmitted to the power-off switch and the audible and visual alarm, and the fire extinguishing particles of the fire extinguishing component are used to contain the spread of the fire.

[0008] Preferably, a heat insulation cover is arranged outside the monitoring socket. The conveying component includes a conveying seat installed inside the monitoring socket, and the conveying seat is threadedly connected to the monitoring component.

[0009] Preferably, a conveying ring for heat transfer is arranged inside the conveying seat. A transmission piece is connected to the conveying seat. A heat dissipation seat is arranged inside the monitoring socket, and the transmission piece penetrates and is connected to the heat dissipation seat.

[0010] Preferably, a second shape memory metal sheet is connected to the transmission sheet. The fire extinguishing assembly includes a steel wire rope connected to the second shape memory metal sheet, and the other end of the steel wire rope is connected to a second baffle. After the second shape memory metal sheet deforms, it pulls the steel wire rope, causing the second baffle to move.

[0011] Preferably, the second baffle is located at the bottom of the storage box. Fire extinguishing particles are arranged inside the storage box. A first through hole is formed in the bottom of the storage box, and a second through hole is formed in the second baffle.

[0012] Preferably, auxiliary components are arranged on both sides of the monitoring seat. The auxiliary components include first through grooves formed on both sides of the monitoring seat, and first baffles are installed inside the first through grooves.

[0013] Preferably, a transmission sheet is connected to the first baffle. A first shape memory metal sheet adapted to the heat dissipation groove is arranged inside the first baffle, and a moisture-proof box for storing moisture-proof particles is arranged on the inner side of the first baffle.

[0014] Preferably, the fire extinguishing assembly includes a storage groove formed on the inner side of the heat dissipation seat. A second through groove is formed on the inner side of the heat dissipation seat, and the second through groove is formed in a semi-circular shape.

[0015] Preferably, a third shape memory metal sheet for blocking the second through groove is arranged on the inner side of the heat dissipation seat. The third shape memory metal sheet is arranged in a multi-combination alloy intersection, and after the third shape memory metal sheet deforms, it contacts the charging wire.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: For this highly adaptable electric vehicle charging pile leakage detection device, after the second shape memory metal sheet deforms, the contact sheet on its surface contacts the contact sheet on the inner side of the monitoring seat to generate a leakage signal, and the signal is transmitted to the power-off switch and the sound and light alarm. The fire extinguishing particles of the fire extinguishing assembly are used to contain the spread of the fire. The overall structure is simple, reducing the problem of increased energy consumption caused by setting up drying or heat dissipation structures to reduce the leakage efficiency, reducing the problem of increased volume of the charging pile due to complex structures, and reducing the problem of property losses caused by setting up complex mechanisms. The specific content is as follows: When the second shape memory metal sheet of the conveying assembly deforms, the leakage signal is transmitted to the power-off switch and the sound and light alarm. The fire extinguishing particles of the fire extinguishing assembly are used to contain the spread of the fire. The overall structure is simple, reducing the problem of increased energy consumption caused by setting up drying or heat dissipation structures to reduce the leakage efficiency, and reducing the problem of property losses caused by setting up complex mechanisms.

[0017] The monitoring component is installed on the conveying base, which facilitates the conveying ring inside the conveying base to adsorb the heat on the monitoring component and then transfer it. The conveying ring transports the heat, ensuring that the monitoring component is always within the appropriate working temperature range and maintaining its stable monitoring performance. The second shape memory metal sheet drives the second baffle to move at the bottom of the storage box through the steel wire rope, facilitating the falling of the fire extinguishing particles inside the storage box. The whole process does not require additional driving, improving the overall processing efficiency.

[0018] The first shape memory metal sheet opens the heat dissipation slots on the first baffle, allowing gas to be conveyed into the monitoring base through the first through groove on the side of the monitoring base. The gas circulation conveys the heat, quickly reducing the temperature inside the monitoring base and enhancing the stability of the device operation.

[0019] Since a moisture-proof box is provided inside the first through groove of the monitoring base and moisture-proof particles are provided inside the moisture-proof box, the gas passing through the moisture-proof box is dehumidified, effectively preventing moist air from entering the monitoring base and reducing the problem that the monitoring effect is poor due to the monitoring component being short-circuited by moisture.

[0020] The third shape memory metal sheet deforms. Since the third shape memory metal sheets are staggered, it is convenient for the third shape memory metal sheet to tilt after deformation. This not only facilitates guiding the fire extinguishing particles so that they fall on the charging wire surface, but also conveniently separates both ends of the charging wire, quickly extinguishing the fire at the connection between the charging base and the charging wire, reducing the problem that the overall fire intensifies due to the rapid combustion of the charging wire after catching fire.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1: In this embodiment, the fire extinguishing particles inside the storage box 19 fall down, and the whole does not need additional driving, which improves the overall processing efficiency. In the emergency situation of fire caused by leakage, the fire extinguishing component can be quickly and reliably started to quickly curb the spread of fire, thereby improving the overall safety. Figures 1 - 9The described technical solution includes a charging pile 1 provided. Inside the charging pile 1, there is a charging base 2 for connecting the charging cable. On the side of the charging base 2, a monitoring base 3 is installed. Inside the monitoring base 3, there is a monitoring component 4 for leakage detection. Inside the charging pile 1, a power-off switch 5 for rapid power-off is installed. On the charging pile 1, an audible and visual alarm 6 for warning is installed. The monitoring component 4, the power-off switch 5, and the audible and visual alarm 6 are electrically connected. Inside the monitoring base 3, a fire extinguishing component is connected through a conveying component. The conveying component includes a second shape memory metal sheet 16 for deformation. After the second shape memory metal sheet 16 deforms, the contact sheet on its surface contacts the contact sheet inside the monitoring base 3 to generate a leakage signal, and the signal is transmitted to the power-off switch 5 and the audible and visual alarm 6. The fire extinguishing particles of the fire extinguishing component are used to contain the spread of the fire. Outside the monitoring base 3, there is a heat insulation cover 7. The conveying component includes a conveying base 8 installed inside the monitoring base 3. The conveying base 8 is threadedly connected to the monitoring component 4. Inside the conveying base 8, there is a conveying ring 9 for heat transfer. A transmission sheet 10 is connected to the conveying base 8. Inside the monitoring base 3, there is a heat dissipation base 11. The transmission sheet 10 passes through and is connected to the heat dissipation base 11. The second shape memory metal sheet 16 is connected to the transmission sheet 10. The fire extinguishing component includes a steel wire rope 17 connected to the second shape memory metal sheet 16. The other end of the steel wire rope 17 is connected to a second baffle 18. After the second shape memory metal sheet 16 deforms, it pulls the steel wire rope 17, causing the second baffle 18 to move. The second baffle 18 is located at the bottom of the storage box 19. Inside the storage box 19, there are fire extinguishing particles. A first through hole 20 is opened at the bottom of the storage box 19. A second through hole 21 is opened on the second baffle 18. The charging base 2 of the charging pile 1 facilitates the connection of the charging cable. At this time, the monitoring base 3 is installed outside the charging base 2. In this application, the monitoring component 4 is set at the connection between the charging base 2 and the charging cable. Since the monitoring component 4 uses a high-precision temperature sensor, it can accurately and sensitively sense the temperature change caused by the leakage current change, ensuring a response at the first moment of leakage. Therefore, the monitoring component 4 can adjust the installation position according to the production design of the charging pile 1 to improve the overall scope of application. When the monitoring component 4 detects leakage of the charging pile 1, when the charging pile 1 leaks, the heat of the connected charging cable increases, causing the second shape memory metal sheet 16 to deform. The contact sheet on the second shape memory metal sheet 16 contacts the contact sheet inside the monitoring base 3, causing the leakage signal to be transmitted to the power-off switch 5. The power-off switch 5 closes, and rapid power-off greatly improves the overall safety, effectively avoiding the electric shock risk and damage to electrical equipment caused by leakage. The installed audible and visual alarm 6 is turned on. Through the high-decibel and strong light warning functions of the audible and visual alarm 6, it can attract the attention of staff and surrounding people from a long distance in a noisy environment and timely remind the on-site personnel to take corresponding measures. Since there is a heat insulation cover 7 outside the monitoring base 3, the heat insulation cover 7 can not only protect the electronic components inside the monitoring base 3 from high-temperature interference but also extend the service life of the monitoring component 4. The monitoring component 4 is installed on the conveying base 8,The conveying ring 9 inside the convenient conveying seat 8 adsorbs the heat on the monitoring part 4 and then transmits it. The conveying ring 9 conveys the heat, ensuring that the monitoring part 4 is always within the suitable working temperature range and maintaining its stable monitoring performance. The conveying ring 9 conveys the heat to the heat dissipation seat 11 through the transmission piece 10. The transmission piece 10 has excellent heat conduction performance and can quickly transfer the heat to the heat dissipation seat 11, enabling the heat dissipation seat 11 to quickly dissipate heat through the heat dissipation grooves opened on its surface. The heat on the heat dissipation seat 11 is transmitted to the second shape memory metal sheet 16 through the transmission piece 10. The overall structure is simple, reducing the problem of increased energy consumption caused by setting up drying or heat dissipation structures to reduce the leakage current efficiency, and reducing the problem of the increase in the volume of the charging pile 1 due to complex structures. When the second shape memory metal sheet 16 deforms, the second shape memory metal sheet 16 drives the second baffle 18 to move at the bottom of the storage box 19 through the steel wire rope 17, so that the second through hole 21 on the second baffle 18 is aligned with the first through hole 20 at the bottom of the storage box 19, facilitating the falling of the fire extinguishing particles inside the storage box 19. The whole does not require additional driving, improving the overall processing efficiency. In the emergency situation of a fire caused by electric leakage, the fire extinguishing component can be quickly and reliably activated to quickly contain the spread of the fire, improving the overall safety and reducing the problem of property loss caused by setting up complex mechanisms.,

[0025] Embodiment 2: In this embodiment, moisture-proof particles are provided inside the moisture-proof box 15. Therefore, the gas passing through the moisture-proof box 15 is dehumidified, effectively preventing moist air from entering the inside of the monitoring seat 3 and reducing the problem that the monitoring effect is poor due to the monitoring part 4 being short-circuited by moisture. Specifically, as Figures 1 - 9 shown, it is disclosed that: auxiliary components are provided on both sides of the monitoring seat 3. The auxiliary components include first through grooves 14 opened on both sides of the monitoring seat 3. A first baffle 12 is installed inside the first through grooves 14. A transmission piece 10 is connected to the first baffle 12. A first shape memory metal sheet 13 adapted to the heat dissipation grooves is provided inside the first baffle 12. A moisture-proof box 15 for storing moisture-proof particles is provided inside the inner side of the first baffle 12. When the transmission piece 10 conveys heat to the heat dissipation seat 11, part of the heat is transmitted to the first baffle 12 through the transmission piece 10, causing the first shape memory metal sheet 13 inside the first baffle 12 to deform. The first shape memory metal sheet 13 opens the heat dissipation grooves on the first baffle 12, enabling gas to be conveyed into the monitoring seat 3 through the first through grooves 14 at the side end of the monitoring seat 3, so that the gas circulation conveys the heat, quickly reducing the temperature inside the monitoring seat 3 and ensuring that the monitoring part 4 works in a normal temperature environment, improving the stability of the device operation. Since the moisture-proof box 15 is provided inside the inner side of the first through groove 14 of the monitoring seat 3 and moisture-proof particles are provided inside the moisture-proof box 15, the gas passing through the moisture-proof box 15 is dehumidified, effectively preventing moist air from entering the inside of the monitoring seat 3 and reducing the problem that the monitoring effect is poor due to the monitoring part 4 being short-circuited by moisture, further improving the reliability of the device.,

[0026] Embodiment 3: In this embodiment, the third shape memory metal sheet 24 is convenient for tilting after deformation, which not only facilitates guiding the fire extinguishing particles so that the fire extinguishing particles fall on the surface of the charging cable, but also facilitates separating the two ends of the charging cable, reducing the risk of rapid spread of the fire after the charging cable catches fire and causing the overall fire to increase. Specifically, as shown in Figures 1 - 3 , Figure 10 and Figure 11 : The fire extinguishing assembly includes a storage groove 22 opened inside the heat dissipation base 11. A second through groove 23 is opened inside the heat dissipation base 11, and the second through groove 23 is opened in a semi-circular shape. A third shape memory metal sheet 24 for blocking the second through groove 23 is arranged inside the heat dissipation base 11. The third shape memory metal sheet 24 is arranged with multiple alloy combinations in an interleaved manner, and the third shape memory metal sheet 24 contacts the charging cable after deformation. The conveying ring 9 conveys heat to the heat dissipation base 11 through the transmission sheet 10. When the charging pile 1 leaks electricity, the heat of the connected charging cable increases, and the heat of the heat dissipation base 11 is conveyed to the third shape memory metal sheet 24, causing the third shape memory metal sheet 24 to deform, opening the second through groove 23 of the heat dissipation base 11, facilitating the fall of the fire extinguishing particles in the storage groove 22 of the heat dissipation base 11, and quickly extinguishing the fire at the connection between the charging base 2 and the charging cable. The second through groove 23 is opened in a semi-circular arc shape, enabling the fire extinguishing particles to be released at multiple angles, improving the effectiveness of fire extinguishing, and minimizing the losses caused by the fire to the greatest extent. Since the third shape memory metal sheet 24 is arranged in an interleaved manner, the third shape memory metal sheet 24 is convenient for tilting after deformation, which not only facilitates guiding the fire extinguishing particles so that the fire extinguishing particles fall on the surface of the charging cable, but also facilitates separating the two ends of the charging cable, reducing the risk of rapid spread of the fire after the charging cable catches fire and causing the overall fire to increase, and improving the overall safety.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
