Description

Technical Field

[0001] This invention relates to the technical field of charging piles, and more particularly to a fireproof outdoor charging pile. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the popularity of electric vehicles continues to rise, and outdoor charging stations, as an important supporting facility, have also been widely used. However, the accompanying charging safety issues, especially the risk of fire, have increasingly attracted widespread attention from all sectors of society. In actual operation, accidents involving spontaneous combustion of electric vehicles during charging due to battery failure, overcharging, short circuits, and other reasons occur frequently. Once a vehicle catches fire, the flames and high temperatures can spread rapidly to the surrounding area, posing a serious threat to charging stations.

[0003] Currently, the industry generally adopts passive protection measures for fire protection of charging piles, such as installing fireproof boards, fireproof partitions, or fireproof roller shutters around the charging pile body. These structures can block external fire sources to a certain extent and delay the direct attack of flames on the charging pile's outer shell and internal components. However, these protective measures have obvious limitations: the charging pile must establish a physical connection with the electric vehicle through the charging gun and cable to achieve power transmission. This rigid electrical connection creates a "weak channel" that cannot be completely sealed off by the external fireproof structure. When an electric vehicle spontaneously combusts, flames, high-temperature smoke, and combustion products can easily spread along the cable surface and be conducted back to the charging pile through the cable path. Even if the fire barrier outside the charging pile is temporarily effective, the fire can still penetrate the charging pile's electrical interface, control module, and even power supply unit along the cable, causing damage to internal components, short circuits, and potentially leading to the charging pile itself catching fire or exploding. More seriously, a fire at a single charging pile can trigger a chain reaction through cable trays, adjacent equipment, or heat radiation, ultimately leading to a large-scale fire in the entire charging station, causing significant property damage and public safety risks. Summary of the Invention

[0004] In view of this, the present invention provides a fireproof outdoor charging pile that overcomes the shortcomings of existing charging piles where the fireproof board added to the outside of the charging pile cannot completely block the intrusion of flames, and the flames can easily spread along the cable surface and be conducted back to the inside of the charging pile through the cable path.

[0005] The technical implementation scheme of the present invention is as follows: a fireproof outdoor charging pile, comprising: a shell with a square hole; a mounting base disposed inside the shell; a charging pile body mounted on the mounting base, with the charging pile body located within the square hole; a controller mounted on the side of the shell; flame sensors symmetrically mounted on the charging pile body; a first cable connected to the side of the charging pile body; a first connector mounted on the mounting base, with the end of the first cable connected to the first connector; a conductive slip ring mounted inside the shell; a second cable connected to the conductive slip ring; a first plug mounted on the end of the second cable, with the first plug inserted into the first connector; and a winding reel for rotation. The system comprises: a dynamic connection inside the housing; a drive motor, installed inside the housing, with its output shaft connected to a winding reel; a third cable, wound on the winding reel, with one end connected to a conductive slip ring; a second connector, installed at the other end of the third cable; a charging gun, placed on the charging pile; a second plug, installed on the charging gun, and inserted into the second connector; an electromagnet, installed on the second connector, which magnetically attracts the charging gun; a disengagement assembly, located on the second connector, used to drive the second plug to disengage from the second connector; and a lifting assembly, located on the housing, used to drive the charging pile to rise and fall.

[0006] Furthermore, the detachment assembly includes: a temperature sensor mounted on the second connector; a ring slidably connected inside the second connector; and a connecting spring, with its two ends connected to the ring and the second connector respectively.

[0007] Furthermore, the lifting assembly includes: a storage frame connected to the outer casing and located directly below the mounting base; a guide rod connected inside the storage frame and slidably connected to the mounting base; a lead screw motor installed inside the storage frame, with the lead screw of the motor slidingly penetrating the bottom of the mounting base; a lifting frame slidably connected to the guide rod, with the lead screw of the motor threadedly connected to the lifting frame; a buffer mechanism located inside the storage frame for buffering the mounting base; a locking mechanism located inside the outer casing for locking the mounting base; and a sealing mechanism located on the outer casing for sealing the square hole.

[0008] Furthermore, the cushioning mechanism includes: a cushioning frame, which is slidably connected to the storage frame; and a cushioning spring, with its two ends connected to the cushioning frame and the storage frame, respectively.

[0009] Furthermore, the locking mechanism includes: an electric push rod, symmetrically installed inside the housing; and a top block, connected to the telescopic rod of the electric push rod, with the top of the top block contacting the bottom of the mounting base.

[0010] Furthermore, the sealing mechanism includes: a top cover connected to the top of the charging pile body; a fixing ring connected to the top of the outer shell; an arc-shaped baffle slidably connected to the fixing ring at circumferential intervals; a first gear ring rotatably connected to the inner shell, and the first gear ring has arc-shaped grooves spaced apart circumferentially; a first motor installed in the inner shell; a first gear connected to the output shaft of the first motor, and the first gear meshes with the first gear ring; and a short rod connected to the side of the arc-shaped baffle, and the short rod slides in the arc-shaped groove.

[0011] Furthermore, it also includes a fire extinguishing assembly, which includes: a rotating frame rotatably connected to the bottom of the top cover; a third motor mounted on the rotating frame; a nozzle connected to the output shaft of the third motor; a water tank connected to the mounting base; a water suction pipe connected to the water tank and kept in communication; a water pump installed inside the charging pile, with the end of the water suction pipe connected to the inlet of the water pump and kept in communication; a water outlet pipe connected to the outlet of the water pump and kept in communication, with the end of the water outlet pipe connected to the nozzle and kept in communication; a second motor mounted on the bottom of the top cover; a second gear ring connected to the rotating frame; and a second gear connected to the output shaft of the second motor, with the second gear meshing with the second gear ring.

[0012] Furthermore, it also includes: a brush tube connected to the top of the housing, and a third cable sliding through the inside of the brush tube.

[0013] Furthermore, it also includes an alarm, installed on the top of the cover.

[0014] The present invention has the following advantages: 1. The present invention uses a disconnection assembly consisting of a temperature sensor, a ring, and a connecting spring installed on the second connector. When an abnormal temperature is detected at the second connector, the second plug can be automatically driven to quickly disconnect from the second connector, cutting off the charging circuit. At the same time, after the flame sensor detects an open flame, it can control the drive motor to drive the winding wheel to retract the third cable, pulling the live part back to a safe area. With the help of the lifting assembly consisting of a screw motor, a lifting frame, a buffer frame, and a buffer spring, the entire charging pile can automatically descend into the underground storage frame in the event of a fire, achieving physical isolation from the external fire scene and fundamentally solving the problem of flames spreading into the charging pile along the cable.

[0015] 2. This invention integrates a fire extinguishing assembly consisting of a water pump, water tank, nozzle, second motor, and third motor. When the flame sensor detects an initial small fire, it can automatically control the nozzle to rotate and spray water at the fire source to attempt to extinguish the fire. If the fire expands and cannot be controlled, a retreat procedure is initiated. After the charging pile body descends, the top cover contacts the square hole on the top of the outer shell to form the first seal. Subsequently, the first motor drives the first gear to rotate the first gear ring, which pushes the short rod through the arc groove, causing the circumferentially distributed arc baffles to converge towards the center, tightly covering the gap between the top cover and the outer shell, forming the second dynamic seal. This completely encloses the core components of the charging pile in the fireproof chamber, preventing the intrusion of high-temperature smoke.

[0016] 3. After a fire is extinguished, this invention can drive the lifting frame to rise by controlling the screw motor, smoothly raising and resetting the charging pile body, and automatically reconnecting the first connector and the first plug to restore the power supply connection. The top block driven by the electric push rod can relock the mounting base to ensure its stability. In addition, the brush tube set at the cable outlet can automatically clean its surface during cable winding and unwinding to prevent debris from being brought into the equipment. The alarm on the top can sound an alarm when the equipment enters the protection state to promptly notify the management personnel. The entire mechanism can realize automation from disaster early warning and proactive response to post-disaster recovery, greatly reducing the need for manual intervention and post-disaster maintenance time.

[0030] like Figure 5 As shown, the disconnection assembly includes a temperature sensor 18, a ring 19, and a connecting spring 20. The temperature sensor 18 is installed at the rear of the second connector 14, and the ring 19 is slidably connected inside the second connector 14. The connecting spring 20 connects the ring 19 and the second connector 14.

[0031] like Figures 6-8As shown, the lifting assembly includes a storage frame 21, a guide rod 22, a lead screw motor 23, a lifting frame 24, a buffer mechanism, a locking mechanism, and a closing mechanism. The storage frame 21 is connected to the right side of the outer casing 1, and the storage frame 21 is located directly below the mounting base 2. The guide rod 22 is connected to the front side of the inside of the storage frame 21. The front part of the mounting base 2 is slidably connected to the guide rod 22. The lead screw motor 23 is installed on the rear side of the inside of the storage frame 21, and the lead screw of the lead screw motor 23 slides through the rear part of the mounting base 2. The guide rod 24... A lifting frame 24 is slidably connected to the upper part of the storage frame 21, and the lead screw of the lead screw motor 23 is threadedly connected to the rear part of the lifting frame 24. A buffer mechanism for buffering the mounting base 2 is provided inside the storage frame 21, and a locking mechanism for locking the mounting base 2 is provided inside the outer shell 1. A closing mechanism for closing the square hole 101 is provided on the outer shell 1. The buffer mechanism includes a buffer frame 25 and a buffer spring 26. The buffer frame 25 is slidably connected to the lower side inside the storage frame 21, and the buffer frame 25 is connected to the storage frame 21. There is a buffer spring 26; the locking mechanism includes an electric push rod 27 and a top block 28. Two electric push rods 27 are symmetrically installed on the upper side of the inner side of the outer casing 1. The top block 28 is connected to the telescopic rod of the electric push rod 27, and the top of the top block 28 contacts the bottom of the mounting base 2; the closing mechanism includes a top cover 29, a fixing ring 30, an arc-shaped baffle 31, a first gear ring 32, a first motor 33, a first gear 34, and a short rod 35. The top of the charging pile body 3 is connected to the top of the top of the charging pile body 3, and a fixing ring 20 is connected to the top right side of the outer casing 1. Ring 30, fixed ring 30 is circumferentially slidably connected with multiple arc-shaped baffles 31, the upper right side of the inside of the outer shell 1 is rotatably connected with a first gear ring 32, and the first gear ring 32 is circumferentially spaced with arc-shaped grooves 3201, the top right front side of the inside of the outer shell 1 is installed with a first motor 33, the output shaft of the first motor 33 is connected with a first gear 34, and the first gear 34 meshes with the first gear ring 32, and each arc-shaped baffle 31 is connected to a short rod 35 on its side, and the short rod 35 slides in the arc-shaped groove 3201.

[0032] Initially, the second connector 14 and the second plug 16 are in a plugged-in state, that is, the ring 19 is in contact with the second plug 16, and the connecting spring 20 is compressed; the top block 28 supports the bottom of the charging pile body 3; when the charging pile is installed, first fix the bottom of the outer shell 1 to the ground, and bury the storage frame 21 underground; when it is necessary to use the charging pile to charge an electric vehicle, the charging gun 15 can be removed from the charging pile body 3, and then the charging gun 15 can be inserted into the charging port of the electric vehicle, so that the charging pile body 3 can be connected to the electric vehicle through the first cable 6, the first connector 7, the conductive slip ring 8, the second cable 9, the first plug 10, the third cable 13, the second connector 14, the second plug 16 and the charging gun 15, and can charge the electric vehicle. The flame sensor 5 can monitor in real time whether there is a flame around the charging pile 3, and the temperature sensor 18 can monitor the temperature of the second connector 14 in real time. When the electric vehicle is overcharged, the temperature detected by the temperature sensor 18 will be higher than the preset value. At this time, the temperature sensor 18 will send a signal. After receiving the signal, the controller 4 will control the electromagnet 17 to cut off the power. At this time, the connecting spring 20 will return to its original state, driving the ring 19 to move closer to the second plug 16, thereby pushing the second plug 16 to disengage from the second connector 14, thus automatically stopping the charging of the electric vehicle and preventing the electric vehicle from spontaneously combusting. When the flame sensor 5 detects a flame around the charging pile 3, the flame sensor 5 will send a signal. After receiving the signal, the controller 4 will... The electromagnet 17 is de-energized to disengage the second plug 16 from the second connector 14. Then, the controller 4 controls the drive motor 12 to rotate the winding wheel 11, causing it to wind the third cable 13. The third cable 13 then moves the second connector 14 away from the electric vehicle. Simultaneously, the controller 4 controls the electric push rod 27 to move the top blocks 28 on both sides to opposite sides, causing the top of the top blocks 28 to detach from the bottom of the mounting base 2. At this point, the mounting base 2 and the charging pile body 3 fall downwards into the storage frame 21 due to gravity. The mounting base 2 then moves the first connector 7 and the top cover 29 downwards, causing the first connector 7 to detach from the first plug 10. The bottom of the mounting base 2 then contacts the top of the buffer frame 25, causing the buffer frame 25 to... 5. When pressed downwards, the buffer spring 26 is compressed, which plays a buffering role. At this time, the bottom of the top cover 29 contacts the top of the outer shell 1, and the top cover 29 blocks the square hole 101. Then, the controller 4 controls the first motor 33 to drive the first gear 34 to rotate. The first gear 34 can drive the first gear ring 32 to rotate at a specified angle. The first gear ring 32 can squeeze the short rod 35 to move closer to the center of the top cover 29 through the arc groove 3201. The short rod 35 drives the arc baffle 31 to move closer to the center of the top cover 29, so that the arc baffle 31 is in contact with the top cover 29. The arc baffle 31 can block the gap between the top cover 29 and the outer shell 1, which plays a sealing role. In this way, the charging pile body 3 can be sealed and stored in the storage frame 21 to prevent the charging pile body 3 from being damaged by flames.After the flames around the charging pile body 3 are extinguished, the controller 4 can control the first motor 33 to drive the first gear 34 to reverse. The first gear 34 can drive the first gear ring 32 to reverse by a specified angle. The first gear ring 32 can squeeze the short rod 35 to move away from the center of the top cover 29 through the arc groove 3201 and reset. The short rod 35 drives the arc baffle 31 to move away from the center of the top cover 29 and reset, so that the arc baffle 31 is disengaged from the top cover 29. Then, the controller 4 controls the lead screw motor 23 to drive the lifting frame 24 to move upward. When the top of the lifting frame 24 contacts the bottom of the mounting base 2, the lifting frame 24 will push the mounting base 2 to move upward. The mounting base 2 can drive the charging pile body 3, the first connector 7 and the top cover 29 to move upward and reset. Mounting base 2 will detach from buffer frame 25, buffer spring 26 will return to its original state, driving buffer frame 25 to move upward and reset. Then, first connector 7 will reconnect with first plug 10. Simultaneously, controller 4 will control electric push rod 27 to drive top blocks 28 on both sides to move to opposite sides and reset, so that the top of top block 28 supports the bottom of mounting base 2. Then, controller 4 will control lead screw motor 23 to drive lifting frame 24 to move downward and reset, so that lifting frame 24 detaches from mounting base 2. Then, controller 4 will control drive motor 12 to drive winding wheel 11 to reverse, so that winding wheel 11 unwinds third cable 13. Then, a new charging gun 15 is plugged into third cable 13, and the charging pile body 3 can be used to charge electric vehicles again.

[0033] like Figure 9 and Figure 10 As shown, it also includes a fire extinguishing assembly, which includes a rotating frame 36, a third motor 37, a nozzle 38, a water tank 39, a water suction pipe 40, a water pump 41, a water outlet pipe 42, a second motor 43, a second gear ring 44, and a second gear 45. The rotating frame 36 is rotatably connected to the bottom of the top cover 29. The third motor 37 is installed on the lower right side of the rotating frame 36. The nozzle 38 is connected to the output shaft of the third motor 37. The water tank 39 is connected to the mounting base 2, and the water suction pipe 40 is connected to the water tank 39 and keeps it in place. The charging pile body 3 is connected to a water pump 41 installed in the middle of the right side. The upper end of the water pump pipe 40 is connected to the water inlet of the water pump 41 and is kept in communication. The water outlet of the water pump 41 is connected to the water outlet pipe 42 and is kept in communication. The upper end of the water outlet pipe 42 is connected to the nozzle 38 and is kept in communication. The bottom front side of the top cover 29 is equipped with a second motor 43. A second gear ring 44 is connected to the rotating frame 36. A second gear 45 is connected to the output shaft of the second motor 43 and meshes with the second gear ring 44.

[0034] Initially, the water tank 39 contains a certain amount of water. When the flame sensor 5 detects that the flame around the charging pile 3 is small, the flame sensor 5 will send a signal. After receiving the signal, the controller 4 will control the second motor 43 to drive the second gear 45 to rotate. The second gear 45 will drive the second gear ring 44 to rotate by a specified angle. The second gear ring 44 will drive the rotating frame 36 and the nozzle 38 to rotate by a specified angle, so that the nozzle 38 is aligned with the flame direction. Then, the controller 4 will control the water pump 41 to draw water from the water tank 39 through the water suction pipe 40 and discharge water through the water outlet pipe 4. 2. Water is delivered to the nozzle 38 and sprayed out. At the same time, the controller 4 controls the third motor 37 to drive the nozzle 38 to swing up and down so that the nozzle 38 can spray water to extinguish the fire and prevent the fire from growing and causing huge losses. If the fire is not extinguished, the fire will grow bigger and bigger. When the flame sensor 5 detects that the flame around the charging pile body 3 is large, the flame sensor 5 will send a signal again. After receiving the signal, the controller 4 will control the water pump 41 and the third motor 37 to stop working and control the charging pile body 3 to fall down into the storage box 21 for sealed storage.

[0035] like Figure 1 As shown, it also includes a brush tube 46. The brush tube 46 is connected to the top left side of the housing 1, and the third cable 13 slides through the inside of the brush tube 46. When the winding wheel 11 is winding the third cable 13, the third cable 13 exposed on the outside of the housing 1 will pass through the brush tube 46 and enter the inside of the housing 1. At this time, the brush tube 46 can brush and clean the surface of the third cable 13 to prevent debris from entering the inside of the housing 1.

[0036] like Figure 9 As shown, it also includes an alarm 47, which is installed on the top of the top cover 29. When the charging pile body 3 falls down into the storage box 21 for sealed storage, the controller 4 will control the alarm 47 to sound an alarm to prompt the staff to extinguish the fire as soon as possible.
