Description

Technical Field

[0001] This invention relates to the field of vehicle charging pile technology, specifically a fireproof new energy vehicle charging pile. Background Technology

[0002] New energy vehicle charging stations are infrastructure that provides electricity for electric vehicles, and they are divided into AC charging stations and DC charging stations. AC charging stations are suitable for slow charging and are usually installed in residential areas and shopping malls; DC charging stations provide fast charging and are commonly found on highways and in urban charging stations. With the increasing popularity of electric vehicles, the number of charging stations is constantly increasing, gradually promoting the development of green travel and intelligent transportation.

[0003] Chinese patent CN222116589U discloses a fire-resistant charging pile for new energy vehicles, including a housing. The housing houses a DC charging module and an electrical system. A heat dissipation window, comprising several vents and louvered grilles, is located on the side of the housing. An aerosol fire extinguishing device is installed on the top of the housing, with its aerosol nozzles facing downwards into the housing's internal cavity. A movable sealing plate, with several flow holes, is positioned between the louvered grilles and the vents. The movable sealing plate slides between an open and a closed position. When in the open position, the flow holes correspond one-to-one with the vents, connecting the internal cavity of the housing and the ventilation gap between the louvered grilles. When in the closed position, the flow holes are staggered with the vents, sealing the vents. This patent provides a fire-resistant charging pile for new energy vehicles with superior fire resistance.

[0004] However, current charging piles have the following problems: when charging vehicles, if a car spontaneously combusts due to some unforeseen circumstances, the charging pile cannot quickly deal with the situation, which often leads to serious disasters and fails to meet safety requirements. Therefore, we propose a fireproof new energy vehicle charging pile. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a fire-resistant new energy vehicle charging pile, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fireproof new energy vehicle charging pile, comprising a charging pile body, a fireproof device installed on the top of the charging pile body, the fireproof device comprising a canopy, the canopy being fixed to the top of the charging pile body, side frames being fixed on both sides of the top of the canopy, a winding column being rotatably installed between the two side frames, the winding column being driven by a motor, and the motor being fixed to the outer wall of one side frame, a fireproof curtain being fixed to the outside of the winding column, a counterweight plate being fixed to the end of the fireproof curtain away from the winding column, an opening for the fireproof curtain to pass through in the top of the canopy, and a fire alarm being fixed to the bottom of the canopy.

[0007] According to the above technical solution, a water pipe is fixed at the bottom of the canopy and the water pipe is connected to an external water source. Several nozzles are fixed at the bottom of the water pipe and the nozzles are set towards the fireproof curtain.

[0008] According to the above technical solution, elastic telescopic plates are fixed on both sides of the bottom of the canopy. An inclined plate is fixed on the side of the telescopic end of the elastic telescopic plate away from the main body of the charging pile. The two inclined plates are respectively in contact with the two sides of the fireproof curtain close to the main body of the charging pile.

[0009] According to the above technical solution, a wire pulling device is provided at the main body of the charging pile. The wire pulling device includes a winding reel fixed to the end face of the winding column, a wire reel rotatably installed on the top of the canopy via a bracket, and a bidirectional elastic telescopic rod slidably installed on the back of the main body of the charging pile. Two U-shaped frames are fixed to the telescopic ends on both sides of the bidirectional elastic telescopic rod. A rotating roller is rotatably installed between the top and bottom of the two U-shaped frames on one side. An elastic telescopic column is fixed to the outer wall of the fixed end of the bidirectional elastic telescopic rod. A Z-shaped rod is fixed to the top of the telescopic end of the elastic telescopic column. A pull wire is fixed to the outside of the Z-shaped rod. The end of the pull wire away from the Z-shaped rod passes through the wire reel and is fixed to the outer wall of the winding reel.

[0010] According to the above technical solution, the surface of the rotating roller is smooth, and the charging cable of the charging pile body passes between the two rotating rollers on one side.

[0011] According to the above technical solution, the cable pulling device also includes two Z-shaped inclined groove plates fixed on the back of the charging pile body, and two L-shaped columns fixed on the telescopic ends of the bidirectional elastic telescopic rod respectively. The Z-shaped inclined groove plates have Z-shaped inclined grooves on their outer sides, and the L-shaped columns are slidably installed inside the Z-shaped inclined grooves of the Z-shaped inclined groove plates on the side away from the telescopic end of the bidirectional elastic telescopic rod.

[0012] According to the above technical solution, a fixing device is provided at the U-shaped frame. The fixing device includes a fixing plate, which is fixed to the outer wall of the charging pile body. Two positioning columns are horizontally inserted and slidably installed on the front side of the fixing plate. A sliding plate is fixed between the rear sides of the two positioning columns, and a spring is provided between the sliding plate and the fixing plate. Anti-slip pads are fixed on the sides of the sliding plate and the fixing plate that are close to each other. A Z-shaped guide rod is fixed on the rear side of the sliding plate. Arc-shaped plates are fixed on both sides of the fixed end of the bidirectional elastic telescopic rod.

[0013] According to the above technical solution, the front side of the arc block plate is semi-circular, and the Z-shaped guide rod is located on the semi-circular motion trajectory of the arc block plate.

[0014] This invention provides a fire-resistant charging pile for new energy vehicles. It has the following beneficial effects: (1) The present invention enables the fireproof curtain to be rapidly deployed under the drive of the motor through the setting of the fireproof device, forming a physical barrier to isolate the fire source from the main body of the charging pile and prevent the fire from spreading. At the same time, the nozzle will spray water flow, which will directly act on the surface of the fireproof curtain, effectively reducing the temperature of the fire source and providing time and space to prevent the fire from spreading. At the same time, under the elastic force of the elastic telescopic plate, the telescopic end of the elastic telescopic plate will drive the inclined plate to always press against the two sides of the fireproof curtain. The inclined plate will push the two sides of the fireproof curtain to bend, so that the fireproof curtain forms a barrier with a certain angle. The bending shape of the fireproof curtain helps to guide the sprayed water flow to concentrate towards the area of ​​the car spontaneous combustion. The water flow concentrated in the fire source area can prevent the fire from spreading to other areas.

[0015] (2) By setting up a wire pulling device, the present invention enables the winding column, winding reel, pull wire, Z-shaped rod, elastic telescopic column, bidirectional elastic telescopic rod, charging pile body, U-shaped frame, rotating roller, L-shaped column rod, and Z-shaped inclined plate to work together to drive the telescopic end of the bidirectional elastic telescopic rod to move upward through the U-shaped frame and drive the rotating roller. During this process, the telescopic end of the bidirectional elastic telescopic rod will also drive the rotating roller to move to both sides through the U-shaped frame, so that the two rotating rollers on one side can quickly pull out the charging wire of the charging pile body in the charging state. By designing an automatic wire pulling mechanism, it can prevent the charging wire of the charging pile body from remaining connected in the event of a fire, reduce the harm of secondary fire, and avoid the charging wire of the charging pile body being exposed near the fire source, which could lead to the problem that the unpulled charging wire may become the fuse for the spread of fire, thereby reducing the risk of damage to the charging pile body.

[0016] (3) By setting up a fixing device, the present invention enables the bidirectional elastic telescopic rod, the arc block plate, the arc block plate, the Z-shaped guide rod, the fixing plate and the anti-slip pad corresponding to the fixing plate to clamp the connection between the charging line of the charging pile body and the charging pile body, thereby avoiding the problem that the charging line of the charging pile body will not be excessively stretched by the rotating roller during the process of the rotating roller pulling the charging line of the charging pile body upward, resulting in the charging line breaking or the interface being damaged.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Please see Figures 1-8One embodiment of the present invention is as follows: a fireproof new energy vehicle charging pile includes a charging pile body 1, a fireproof device 2 is provided on the top of the charging pile body 1, the fireproof device 2 includes a canopy 21, the canopy 21 is fixed to the top of the charging pile body 1, side frames 22 are fixed on both sides of the top of the canopy 21, a winding column 24 is rotatably installed between the two side frames 22, the winding column 24 is driven by a motor 23, and the motor 23 is fixed to the outer wall of one side frame 22, a fireproof curtain 25 is fixed to the outside of the winding column 24, a counterweight plate 26 is fixed to the end of the fireproof curtain 25 away from the winding column 24, an opening is provided on the top of the canopy 21 for the fireproof curtain 25 to pass through, and a fireproof device is fixed at the bottom of the canopy 21. The fire alarm 27 is electrically connected to the motor 23. The fire alarm 27 is an existing device for monitoring fires and will not be described in detail here. A water pipe 28 is fixed at the bottom of the ceiling 21 and is connected to an external water source. Several nozzles 29 are fixed at the bottom of the water pipe 28. The nozzles 29 are set towards the fire curtain 25. Through the above structure, the fire curtain 25 is quickly deployed under the drive of the motor 23 to form a physical barrier, isolate the fire source from the contact between the fire source and the charging pile body 1, and prevent the fire from spreading. At the same time, the nozzles 29 spray water directly onto the surface of the fire curtain 25, effectively reducing the temperature of the fire source and providing time and space to prevent the fire from spreading.

[0021] Both sides of the bottom of the canopy 21 are fixed with elastic telescopic plates 210. The telescopic end of the elastic telescopic plate 210 away from the charging pile body 1 is fixed with a slanted plate 211. The two slanted plates 211 are respectively in contact with the two sides of the fire curtain 25 near the charging pile body 1. Through the above structure, the fire curtain 25 forms a barrier with a certain angle. The curved shape of the fire curtain 25 helps to guide the sprayed water flow towards the area of ​​spontaneous combustion of the car. The water flow is concentrated in the fire source area to prevent the fire from spreading to other areas.

[0022] According to the above technical solution, a cable pulling device 3 is provided at the charging pile body 1. The cable pulling device 3 includes a winding reel 31 fixed to the end face of the winding column 24, a wire reel 32 rotatably installed on the top of the canopy 21 via a bracket, and a bidirectional elastic telescopic rod 36 slidably installed on the back of the charging pile body 1. Two U-shaped frames 37 are fixed to the telescopic ends on both sides of the bidirectional elastic telescopic rod 36. A rotating roller 38 is rotatably installed between the top and bottom of the two U-shaped frames 37 on one side. An elastic telescopic column 35 is fixed to the outer wall of the fixed end of the bidirectional elastic telescopic rod 36. A Z-shaped rod 34 is fixed to the top of the telescopic end of the elastic telescopic column 35. A pull wire 33 is fixed to the outside of the Z-shaped rod 34. The end of the pull wire 33 away from the Z-shaped rod 34 passes through the wire reel 32 and is fixed to the outer wall of the winding reel 31. The surface of the rotating roller 38 is smooth. The smooth surface of the rotating roller 38 effectively reduces the friction between the rotating roller 38 and the charging cable of the charging pile body 1. The charging cable of the charging pile body 1 passes between two rotating rollers 38 on one side. The cable pulling device 3 also includes two Z-shaped inclined groove plates 310 fixed to the back of the charging pile body 1 and two L-shaped columns 39 fixed to the telescopic ends of the bidirectional elastic telescopic rod 36 on both sides. The Z-shaped inclined groove plates 310 have Z-shaped inclined grooves on their outer sides. The L-shaped columns 39 are slidably installed inside the Z-shaped inclined grooves of the Z-shaped inclined groove plates 310 on the side away from the telescopic ends of the bidirectional elastic telescopic rod 36. With the above structure, the rotating rollers 38 can quickly pull out the charging cable of the charging pile body 1 when it is charging. By designing an automatic cable pulling mechanism, it is possible to prevent the charging cable of the charging pile body 1 from remaining connected in the event of a fire, thereby reducing the harm of secondary fires. It can also prevent the charging cable of the charging pile body 1 from being exposed near the fire source, which could lead to the problem that the unpulled charging cable may become the fuse for the spread of fire, thereby reducing the risk of damage to the charging pile body 1.

[0023] In use, if a vehicle spontaneously combusts due to unforeseen circumstances while the charging pile body 1 is charging, the fire alarm 27 detects the fire and transmits an electrical signal to the motor 23 and an external water source. The motor 23 drives the winding column 24 to rotate, causing it to unroll the fireproof curtain 25. The fireproof curtain 25 forms a barrier in the front area of ​​the charging pile body 1. Meanwhile, the external water source delivers water through the water pipe 28 to the nozzle 29, which sprays water onto the surface of the fireproof curtain 25. Driven by the motor 23, the fireproof curtain 25 quickly unfolds, forming a physical barrier that isolates the fire source from contact with the charging pile body 1. To prevent the fire from spreading, nozzle 29 sprays water directly onto the surface of the fire curtain 25, effectively reducing the temperature of the fire source and providing time and space to prevent the fire from spreading. Simultaneously, during the deployment of the fire curtain 25, the elastic extension plate 210 causes its extension end to keep the inclined panel 211 pressed against both sides of the fire curtain 25. The inclined panel 211 bends the sides of the fire curtain 25, thus forming an angled barrier. The curved shape of the fire curtain 25 helps guide the sprayed water towards the area of ​​the vehicle fire, and this concentration of water in the fire source area prevents the fire from spreading to other areas.

[0024] During the rotation of the winding column 24, the winding reel 31 is also driven to rotate. The winding reel 31 drives the pull wire 33 to wind up. The pull wire 33 pulls the bidirectional elastic telescopic rod 36 upward along the back of the charging pile body 1 through the Z-shaped rod 34 and the elastic telescopic column 35. The telescopic end of the bidirectional elastic telescopic rod 36 drives the rotating roller 38 upward through the U-shaped frame 37. Since the charging cable of the charging pile body 1 passes between the two rotating rollers 38 on one side, the upward movement of the rotating roller 38 will pull the charging cable of the charging pile body 1 upward. At the same time, the telescopic end of the bidirectional elastic telescopic rod 36 drives the L-shaped column 39 upward. The L-shaped column 39 is restricted by the Z-shaped groove of the Z-shaped inclined plate 310. The Z-shaped groove of the Z-shaped inclined plate 310 will push the L-shaped column. 39 drives the extension end of the bidirectional elastic telescopic rod 36 to extend, so that the extension end of the bidirectional elastic telescopic rod 36 drives the rotating roller 38 to move upward through the U-shaped frame 37. During this process, the extension end of the bidirectional elastic telescopic rod 36 also drives the rotating roller 38 to move to both sides through the U-shaped frame 37, so that the two rotating rollers 38 on one side can quickly pull out the charging cable of the charging pile body 1 which is in the charging state. By designing an automatic cable pulling mechanism, the charging cable of the charging pile body 1 can be prevented from remaining connected in the event of a fire, reducing the harm of secondary fires. It can also prevent the charging cable of the charging pile body 1 from being exposed near the fire source, which could lead to the problem that the unpulled charging cable may become the fuse for the spread of fire, thereby reducing the risk of damage to the charging pile body 1.

[0025] It should be noted that when the two rotating rollers 38 move to the charging cable connector position of the charging pile body 1, and the pull cable 33 needs to pull the bidirectional elastic telescopic rod 36 upward through the Z-shaped rod 34 and the elastic telescopic column 35, since the two rotating rollers 38 are already at the charging cable connector position of the charging pile body 1, the positions of the rotating rollers 38 and the bidirectional elastic telescopic rod 36 will not be displaced. At this time, the pull cable 33 drives the telescopic end of the elastic telescopic column 35 to stretch upward through the Z-shaped rod 34, thereby avoiding the problem that the rotating rollers 38 will pull the charging cable of the charging pile body 1 too upward when it moves upward, which would cause damage to the charging cable of the charging pile body 1.

[0026] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, a fixing device 4 is provided at the U-shaped frame 37. The fixing device 4 includes a fixing plate 41, which is fixed to the outer wall of the charging pile body 1. Two positioning posts 44 are horizontally inserted through the front side of the fixing plate 41 and slidably installed. A sliding plate 42 is fixed between the rear sides of the two positioning posts 44, and a spring is provided between the sliding plate 42 and the fixing plate 41. Anti-slip pads 43 are fixed on the sides of the sliding plate 42 and the fixing plate 41 that are close to each other. A Z-shaped guide rod 45 is fixed on the rear side of the sliding plate 42, providing bidirectional elasticity. Both sides of the fixed end of the telescopic rod 36 are fixed with arc-shaped plates 46. The front side of the arc-shaped plates 46 is semi-circular. The Z-shaped guide rod 45 is located on the semi-circular movement trajectory of the arc-shaped plates 46. Through the above structure, the fixed plate 41 and the anti-slip pad 43 corresponding to the fixed plate 41 clamp the connection between the charging cable of the charging pile body 1 and the charging pile body 1. This avoids the problem that the charging cable of the charging pile body 1 will not be excessively stretched by the rotating roller 38 during the upward movement of the charging cable of the charging pile body 1, which would cause the charging cable to break or the interface to be damaged.

[0027] During use, as the bidirectional elastic telescopic rod 36 moves upward, it also drives the arc block plate 46 to move upward. The arc block plate 46 pushes the Z-shaped guide rod 45 to move the slide plate 42 towards the fixed plate 41. This allows the fixed plate 41 and the corresponding anti-slip pad 43 to clamp the connection between the charging cable and the charging pile body 1. This avoids the problem of the charging cable of the charging pile body 1 being excessively stretched by the rotating roller 38 during the upward movement of the charging cable, which could lead to cable breakage or interface damage.

[0028] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
