Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a dual-purpose safe charging pile. Background Technology

[0002] Charging piles are charging devices for electric motor vehicles and electric non-motorized vehicles. Most existing charging piles are single-function, often only able to charge one of these two types of vehicles, resulting in low utilization efficiency. Both types of vehicles require several hours or even more than ten hours to charge, necessitating the designation of parking spaces for these vehicles. However, self-service charging piles often suffer from parking space hogging due to a lack of parking spaces and management personnel. This occurs when vehicles that don't need charging remain parked in the charging spaces, or when vehicles fail to leave after charging, effectively occupying charging resources and preventing vehicles that truly need charging from doing so, thus hindering convenience. Furthermore, while existing charging piles provide some flame retardant or fire extinguishing effects for themselves, they cannot extinguish fires on the vehicles being charged. Electric non-motorized vehicles are more prone to battery fires during charging than electric motor vehicles, and traditional charging piles often struggle to control fires promptly, highlighting the shortcomings of current technology. Summary of the Invention

[0003] The purpose of this invention is to provide a dual-purpose safe charging station to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dual-purpose safety charging pile includes a pile body, a support shaft, a worm gear, an intercepting rod, a servo motor, a worm, auxiliary sliders, a power socket, a main slider, a charging cable, a charging gun, a controller, a recognition camera, a rack and pinion, a sliding seat, an electric audible and visual warning rod brake motor, a gear, and a fire extinguishing component. A horizontal support shaft is rotatably connected to the middle of the pile body in a front-rear direction. A worm gear is coaxially fixed to the support shaft. A horizontal intercepting rod is radially fixed to the front of the support shaft. A horizontal servo motor is fixed to the right end of the pile body. A worm gear is coaxially fixed to the shaft of the servo motor, and the worm gear meshes with the worm gear. Multiple horizontal auxiliary sliders are slidably connected to the intercepting rod in a left-right direction. Each auxiliary slider is fixed with a power socket, and each power socket is electrically connected via a spare cable. The left side of the intercepting rod... A main slider is slidably connected, and a charging cable is fixed to the main slider. A charging gun is fixed to one end of the charging cable and is plugged into the main slider. A controller is fixed to the bottom of the inner wall of the pile body. A recognition camera is fixed to the upper right end of the pile body. A horizontal rack is fixed to the rear right end of the interception rod. A horizontal sliding seat is slidably connected to the right side of the interception rod. A horizontal electric audible and visual warning rod is fixed to the upper right end of the sliding seat. A vertical brake motor is fixed to the rear end of the sliding seat. A gear is coaxially fixed to the shaft of the brake motor. The gear meshes with the rack. The controller is electrically connected to the servo motor, charging cable, power socket, recognition camera, electric audible and visual warning rod, and brake motor. The controller is powered by an external power source. The pile body is also equipped with a fire extinguishing component.

[0006] Based on the above technical solution, the fire extinguishing component includes a smoke sensor, a support column, a gear ring, a support frame, an electric push rod, a support rod, a connector, a front spray pipe, a rear spray pipe, a front spray nozzle, a front deflection nozzle, a rear spray nozzle, a rear deflection nozzle, a push-button shut-off valve, a three-way valve, an incomplete gear, a rack frame, a second rack, a third rack, and a fourth rack. A smoke sensor is fixed to the upper part of the pile body. A vertical support column is rotatably connected to the upper part of the pile body. A gear ring is coaxially fixed to the support column. A vertical support frame is fixed to the top of the support column. A vertical electric push rod is fixed to the right side of the support column. A vertical columnar support rod is hinged to the upper part of the support frame. A connector is fixed to the bottom of the support rod. The push rod of the electric push rod can be inserted vertically into the connector. A front spray pipe extending axially is provided at the front of the support rod, and a rear spray pipe extending axially is provided at the rear of the support rod. The front spray pipe is fixedly connected to multiple horizontally directed front spray nozzles. The device comprises a front spray pipe with a forward deflector fixedly connected to its upper part, a rear spray pipe with multiple right-directing rear spray nozzles fixedly connected to its upper part, a rear deflector fixedly connected to its upper part, a push-button shut-off valve fixedly mounted on its upper part, a horizontal three-way valve fixedly mounted on the rear end of the upper inner wall of the pile body, an incomplete gear fixedly coaxially to the operating rod of the three-way valve, a horizontal rack frame slidably connected to the upper part of the pile body, a second rack fixedly mounted on the upper left of the rack frame, a third rack fixedly mounted on the lower right of the rack frame, the second and third racks alternately meshing with the incomplete gear, a horizontal fourth rack fixedly mounted at the front bottom of the rack frame, the fourth rack meshing with a gear ring, the inlet of the push-button shut-off valve connected to pressurized extinguishing agent from the outside via a pipe, the outlet of the push-button shut-off valve connected to the inlet of the three-way valve via a pipe, and the two outlets of the three-way valve connected to the front and rear spray pipes via pipes.

[0007] Based on the above technical solution, two baffles are fixed at the upper and lower ends of the right side of the interceptor rod. The two baffles at the top and the two baffles at the bottom of the interceptor rod are located on the left and right sides of the sliding seat. A damping piston cylinder is hinged to the right side of the support column. The bottom of the support rod is hinged to the piston rod of the damping piston cylinder. A horizontal contact seat with an upwardly convex arc shape and matching the outer wall of the support rod is fixed at the bottom of the operating rod of the press-type shut-off valve. Arc-shaped guide grooves are opened at the front and rear ends of the upper part of the support frame. The two guide grooves are slidably connected to a bellows protective cover. The bellows protective cover is inserted into the support rod.

[0008] Based on the above technical solution, the controller is electrically connected to the smoke sensor and the electric push rod. When the servo motor is energized and rotates in both directions, the support shaft can rotate in both directions through the worm gear and worm wheel. The recognition camera can identify vehicles, personnel, and flames in the front and rear directions. When the brake motor is energized and rotates in both directions, the sliding seat can slide left and right along the interceptor rod through the meshing of the first gear and the first rack. After the push rod of the electric push rod retracts, it can disengage from the insertion of the push rod and the plug seat. When the push rod of the electric push rod is disengaged from the plug seat, the support rod can rotate to the lower right under the action of gravity. When the support rod rotates to the lower right to a certain angle, it can come into contact with the bottom end of the contact seat and press the operating rod of the press-type shut-off valve, thereby opening the press-type shut-off valve. The contact seat is pressed by the support rod, causing the press-type shut-off valve to open. When the pressure-type shut-off valve is in operation, the support rod is in a horizontal state and the front and rear nozzles are in a downward vertical state. When the support rod is in a horizontal state and pressurized fluid is alternately ejected from the front and rear nozzles, the support rod can drive the support column and support frame to rotate back and forth. When the support column rotates back and forth, the rack frame can move back and forth left and right through the gear ring and the fourth rack. When the rack frame moves back and forth left and right, the second and third racks can alternately mesh with the incomplete gear with pauses. When the second and third racks alternately mesh with the incomplete gear with pauses, the incomplete gear can rotate unidirectionally with pauses. When the incomplete gear rotates unidirectionally, it can change the passage direction of the three-way valve. When the passage direction of the incomplete gear changes, it can control the fluid flow to the front or rear injection pipe.

[0009] Compared with the prior art, the present invention has the following advantages: The present invention can raise or lower the barrier bar by controlling the servo motor, and can retract and extend the electric sound and light warning bar by controlling the brake motor, thereby facilitating the entry and exit of electric motor vehicles and electric non-motor vehicles. Then, the charging gun and power socket can be used to charge electric motor vehicles or electric non-motor vehicles at the same time, improving the utilization efficiency of charging pile parking spaces and the device.

[0010] By controlling the raising or lowering of the barrier and the retraction of the electric sound and light warning barrier, combined with the license plate recognition and time-based charging mode using a recognition camera, the occupation of charging station parking spaces by non-charging vehicles can be effectively reduced, improving the convenience of people's lives.

[0011] Fires are detected promptly by smoke sensors and recognition cameras. Then, under the action of electric push rod, contact seat, press-type shut-off valve, gear ring, No. 4 rack, rack carrier, No. 2 rack, No. 3 rack, and three-way valve, pressurized extinguishing agent is alternately sprayed from the front deflector and the rear deflector. This causes the support rod to swing back and forth after it falls, and then the extinguishing agent sprayed from the front and rear nozzles is used to extinguish the fire in the charging pile parking space, control the fire, and reduce economic losses and safety risks.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-7 As shown, a dual-purpose safety charging pile includes a pile body 1, a support shaft 2, a worm gear 3, an interceptor bar 4, a servo motor 5, a worm gear 6, a secondary slider 7, a power socket 8, a main slider 9, a charging cable 10, a charging gun 11, a controller 12, a recognition camera 13, a first rack 14, a sliding seat 15, an electric audible and visual warning bar 16, a brake motor 17, a first gear 18, and a fire extinguishing unit 19. A horizontal support shaft 2 is rotatably connected to the middle of the pile body 1 in the front-rear direction. A worm gear 3 is coaxially fixed to the support shaft 2. A horizontal interceptor bar 4 is radially fixed to the front of the support shaft 2. A horizontal servo motor 5 is fixed to the right end of the pile body 1. A worm gear 6 is coaxially fixed to the shaft of the servo motor 5. The worm gear 6 meshes with the worm wheel 3. Multiple horizontal auxiliary sliders 7 are slidably connected to the intercepting rod 4. Each auxiliary slider 7 is fixed with a power socket 8. The power sockets 8, which move with the auxiliary sliders 7, facilitate charging of electric non-motorized vehicles. Each power socket 8 is electrically connected via a spare cable. A main slider 9 is slidably connected to the left side of the intercepting rod 4. A charging cable 10 is fixed to the main slider 9. A charging gun 11 is fixed to one end of the charging cable 10. The charging gun 11 is inserted into the main slider 9 and moves with the main slider 9. To facilitate easier charging of electric vehicles, a controller 12 is fixed to the bottom of the inner wall of the charging pile 1. A recognition camera 13 is fixed to the upper right end of the charging pile 1. A horizontal rack 14 is fixed to the rear right end of the interception rod 4. A horizontal sliding seat 15 is slidably connected to the right side of the interception rod 4. A horizontal electric audible and visual warning rod 16 is fixed to the upper right end of the sliding seat 15. The electric audible and visual warning rod 16 can intercept electric non-motorized vehicles and activate when the interception rod 4 is raised or lowered, and when it moves left or right with the sliding seat 15. The sliding seat 15 is equipped with a vertical brake motor 17 at its rear end. The brake motor 17 can brake and limit the rotation of the first gear 18, thereby preventing the sliding seat 15 from sliding accidentally along the interceptor bar 4. The first gear 18 is coaxially fixed to the shaft of the brake motor 17. The first gear 18 meshes with the first rack 14. The controller 12 is electrically connected to the servo motor 5, charging cable 10, power socket 8, recognition camera 13, electric sound and light warning bar 16 and brake motor 17. The controller 12 is connected to an external power supply. The pile body 1 is also equipped with a fire extinguishing part 19.

[0022] The fire extinguishing component 19 includes a smoke sensor 20, a support column 21, a gear ring 22, a support frame 23, an electric push rod 24, a support rod 25, a plug-in socket 26, a front spray pipe 27, a rear spray pipe 28, a front spray nozzle 29, a front deflection nozzle 30, a rear spray nozzle 31, a rear deflection nozzle 32, a push-button shut-off valve 33, a three-way valve 34, an incomplete gear 35, a rack frame 36, a second rack 37, a third rack 38, and a fourth rack 39. A smoke sensor 20 is fixed to the upper part of the pile body 1, and a vertical support column 21 is rotatably connected to the upper part of the pile body 1. A gear is coaxially fixed to the support column 21. In circle 22, a vertical support frame 23 is fixed to the top of the support column 21. A vertical electric push rod 24 is fixed to the right side of the support column 21. A vertical columnar support rod 25 is hinged to the upper part of the support frame 23. A plug-in seat 26 is fixed to the bottom of the support rod 25. The push rod of the electric push rod 24 can be inserted vertically into the plug-in seat 26. A front spray pipe 27 extending axially is provided at the front of the support rod 25. A rear spray pipe 28 extending axially is provided at the rear of the support rod 25. The front spray pipe 27 is fixedly connected to a plurality of right-facing horizontal front spray nozzles 29. The upper part of the pipe 27 is fixedly connected to a forward deflection nozzle 30. The rear injection pipe 28 is fixedly connected to multiple right-directing rear injection nozzles 31. The upper part of the rear injection pipe 28 is fixedly connected to a rear deflection nozzle 32. The upper part of the support frame 23 is fixedly connected to a push-button shut-off valve 33. The rear end of the upper inner wall of the pile body 1 is fixedly connected to a horizontal three-way valve 34. The operating rod of the three-way valve 34 is coaxially fixed to an incomplete gear 35. The upper part of the pile body 1 is slidably connected to a horizontal rack frame 36. The upper left part of the rack frame 36 is fixedly connected to a second rack 37, and the lower right part of the rack frame 36 is fixedly connected to a third rack. 38. The second rack 37 and the third rack 38 alternately mesh with the incomplete gear 35. The bottom front end of the rack frame 36 is fixed with a horizontal fourth rack 39, which meshes with the gear ring 22. The inlet of the press-type shut-off valve 33 is connected to the pressurized extinguishing agent in the outside through a pipeline, so that the extinguishing agent always tends to pass through the press-type shut-off valve 33. The outlet of the press-type shut-off valve 33 is connected to the inlet of the three-way valve 34 through a pipeline. The two outlets of the three-way valve 34 are connected to the front spray pipe 27 and the rear spray pipe 28 through pipelines.

[0023] Two baffles 40 are fixed at the top and bottom of the right side of the interceptor rod 4. The two baffles 40 at the top and the two baffles 40 at the bottom of the interceptor rod 4 are located on the left and right sides of the sliding seat 15, thereby preventing the sliding seat 15 from accidentally detaching from the interceptor rod 4. A damping piston cylinder 41 is hinged to the right side of the support column 21. The bottom of the support rod 25 is hinged to the piston rod of the damping piston cylinder 41. The damping piston cylinder 41 can buffer the support rod 25 when it falls, preventing the support rod 25 from falling too fast and causing damage. The bottom of the operating rod of the push-type shut-off valve 33 is fixed with a horizontal, upwardly convex arc-shaped contact seat 42 that matches the outer wall of the support rod 25, so that it can better contact the support rod 25. The upper front and rear ends of the support frame 23 are each opened with an arc-shaped guide groove 43. The two guide grooves 43 are slidably connected to a bellows protective cover 44. The bellows protective cover 44 is inserted into the support rod 25. The bellows protective cover 44 can prevent dust from entering the support frame 23 and reduce pollution.

[0024] The controller 12 is electrically connected to the smoke sensor 20 and the electric push rod 24. When the servo motor 5 is energized and rotates in both directions, the support shaft 2 can rotate in both directions through the worm gear 6 and worm wheel 3. The recognition camera 13 can identify vehicles, personnel, and flames in the front and rear directions. When the brake motor 17 is energized and rotates in both directions, the sliding seat 15 can slide left and right along the interceptor rod 4 through the meshing of the first gear 18 and the first rack 14. After the push rod of the electric push rod 24 is retracted, it can disengage from the insertion of its push rod and the plug seat 26. When the push rod of the electric push rod 24 is disengaged from the plug seat 26, the support rod 25 can rotate to the lower right under the action of gravity. When the support rod 25 rotates to the lower right to a certain angle, it can come into contact with the bottom end of the contact seat 42 and press the operating rod of the press-type shut-off valve 33, thereby opening the press-type shut-off valve 33. When the contact seat 42 is pressed by the support rod 25 and the press-type shut-off valve 33 is opened, the support rod 25 can rotate to the lower right. When the support rod 25 is horizontal and the front nozzle 29 and rear nozzle 31 are vertically pointing downwards, and pressurized fluid is alternately ejected from the front nozzle 29 and rear nozzle 31, the support rod 25 can drive the support column 21 and support frame 23 to rotate back and forth. When the support column 21 rotates back and forth, the rack frame 36 can move back and forth left and right through the gear ring 22 and the fourth rack 39. The rack frame 36's left and right movement enables... The second rack 37 and the third rack 38 engage alternately with the incomplete gear 35 with pauses. When the second rack 37 and the third rack 38 engage alternately with the incomplete gear 35 with pauses, the incomplete gear 35 can rotate unidirectionally with pauses. When the incomplete gear 35 rotates unidirectionally, it can change the passage direction of the three-way valve 34. When the passage direction of the incomplete gear 35 changes, it can control the fluid flow to the forward injection pipe 27 or the rear injection pipe 28.

[0025] Working principle of the invention:

[0026] When in use, install this device at the entrance and exit of the charging pile parking space, with the charging pile parking space located directly in front of this device. The push rod of the electric push rod 24 is plugged into the connector 26, the support rod 25 is in a vertical state, and the three-way valve 34 is connected to the rear injection pipe 28.

[0027] When it is necessary to intercept electric vehicles, the interception bar 4 is in a horizontal position to the right. When the recognition camera 13 recognizes the license plate, it controls the servo motor 5 to rotate forward, thereby using the cooperation of the worm gear 6 and the worm wheel 3 to make the support shaft 2 rotate counterclockwise (from the main viewing angle), thus raising the interception bar 4 to facilitate the car to enter or leave the parking space. After the vehicle has passed, the servo motor 5 is controlled to rotate in reverse to reset the interception bar 4. Then, the charging gun 11 can be used for charging. After charging is completed, the charging gun 11 can be put back.

[0028] When it is necessary to intercept electric non-motorized vehicles, the interception bar 4 is in a horizontal position to the right, and the sliding seat 15 is in the rightmost position of the interception bar 4. When the recognition camera 13 recognizes the license plate of the electric non-motorized vehicle, it will control the brake motor 17 to rotate forward. Then, by using the cooperation of the first gear 18 and the first rack 14, the sliding seat 15 slides to the left along the interception bar 4. When the sliding seat 15 drives the electric sound and light warning bar 16 to move to the left, a certain amount of space is released, which facilitates the entry and exit of electric non-motorized vehicles from the parking space. After the vehicle has passed, the brake motor 17 is controlled to reverse so that the interception bar 4 is reset. Then, the charging can be achieved by connecting the self-provided charger to the power socket 8.

[0029] Whether charging electric motor vehicles or electric non-motor vehicles, the system starts charging by the hour the recognition camera 13 identifies the license plate of the vehicle in the parking space and stops charging by the hour when the vehicle leaves. This charging method reduces the ineffective occupation of the charging station parking space.

[0030] When the smoke sensor 20 detects smoke in the outside environment or the recognition camera 13 detects a vehicle fire in the parking space, the controller 12 will control the electric push rod 24 to retract, thus disengaging it from the connector 26. Subsequently, the support rod 25 rotates downwards and to the right under gravity, gradually pressing the contact seat 42 upwards until the support rod 25 is in a horizontal position to the right. At this point, both the front nozzle 29 and the rear nozzle 31 are in a downward vertical position. The operating lever of the press-type shut-off valve 33 moves upwards along with the contact seat 42, thus opening the press-type shut-off valve 33. At this time, pressurized extinguishing agent will be discharged from the rear nozzle 31 and the rear deflector nozzle 32 through the press-type shut-off valve 33, the three-way valve 34, and the rear spray pipe 28. This drives the support rod 25 to rotate the support frame 23 and support column 21 clockwise (top view). This, in turn, causes the rack frame 36 to slide to the right via the gear ring 22 and the fourth rack 39. As the support rod 25 continues to swing, the rack frame 36 continues to move to the right. This allows the second rack 37 and the third rack 38 to engage with the incomplete gear 35 alternately, with pauses, gradually causing the incomplete gear 35 to mesh with the second rack 37 and rotate clockwise (front view) until it disengages from the second rack 37. During this process, the incomplete gear 35 drives the operating lever of the three-way valve 34 to rotate and then stop, thus changing the flow direction of the three-way valve 34. That is, the connection between the three-way valve 34 and the rear spray pipe 28 is changed to the connection between the three-way valve 34 and the front spray pipe 27. This allows pressurized extinguishing agent to be discharged through the press-type shut-off valve 33, the three-way valve 34, and the front spray pipe 27 from the front spray nozzle 29 and the front deflection nozzle 30. This drives the support rod 25 to rotate the support frame 23 and the support column 21 counterclockwise (from a top view). This causes the rack frame 36 to slide to the left through the gear ring 22 and the fourth rack 39. As the support rod 25 swings further, the rack frame 36 continues to move to the left. This allows the alternating meshing of the second rack 37 and the third rack 38 with the incomplete gear 35, with pauses, to gradually engage the incomplete gear 35 with the third rack 38, thus making the incomplete gear... Wheel 35 rotates clockwise (from the main view angle) until the incomplete gear 35 disengages from the rack 38. During this process, the incomplete gear 35 drives the operating lever of the three-way valve 34 to rotate and then stop, thereby changing the flow direction of the three-way valve 34, from being connected to the front spray pipe 27 to being connected to the rear spray pipe 28. This allows pressurized extinguishing agent to be discharged from the rear spray nozzle 31 and the rear deflector nozzle 32 through the press-type shut-off valve 33, the three-way valve 34, and the rear spray pipe 28. This drives the support rod 25 to rotate clockwise (from the top view angle), causing the support frame 23 and the support column 21. This cycle repeats, allowing the support rod 25 to swing back and forth above the charging pile parking space.This allows the extinguishing agent sprayed from the front nozzle 29 and the rear nozzle 31 to extinguish the fire on the vehicle in the parking space.
