Description

Technical Field

[0001] This invention relates to the field of vehicle power supply technology, specifically to an intelligent charging station for electric vehicles with automatic fire extinguishing function. Background Technology

[0002] An intelligent charging station for electric vehicles is a facility that provides charging services for electric vehicles. It integrates intelligent control, communication technology, and power electronics technology. As the number of electric vehicles continues to increase, the construction of intelligent charging stations for electric vehicles is also constantly developing and improving.

[0003] To effectively prevent electric vehicle fires during charging and avoid spreading the fire to surrounding facilities and vehicles, existing smart charging stations for electric vehicles typically have specific pits under the parking spaces. For example, patent CN221315864U discloses a regional intelligent fire prevention and control platform for electric vehicle charging piles. This platform has an explosion-proof fire pit under each charging space, equipped with a lifting structure and a fire sprinkler system. If a fire breaks out in a charging space, the burning vehicle is lowered into the explosion-proof fire pit, and water is sprayed onto the top of the burning vehicle until it is completely submerged, thus achieving efficient fire extinguishing.

[0004] In practical use, it has been found that the root cause of most electric vehicle fires is battery failure. Current technology, which sprays water directly onto the top of the car, makes it difficult for the water to quickly penetrate to the battery compartment at the bottom, failing to effectively cool and extinguish the fire source in the first instance. This results in the fire being difficult to control in its early stages, missing the golden opportunity for firefighting and greatly increasing the risk of the fire spreading. Therefore, we propose an intelligent charging station for electric vehicles with automatic fire extinguishing capabilities to effectively address these shortcomings. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent charging station for electric vehicles with automatic fire extinguishing function, which solves the problem mentioned in the background art that the prior art cannot extinguish the fire of electric vehicle batteries in a timely manner.

[0006] This invention is achieved through the following technical solution: an intelligent charging station for electric vehicles with automatic fire extinguishing function, including an intelligent charging pile and a sunshade canopy, and also including a fire extinguishing pool. The fire extinguishing pool is buried in the ground below the sunshade canopy. The fire extinguishing pool is provided with a hollow plate that can move up and down. The top of the hollow plate is equipped with a grid plate that matches the opening of the fire extinguishing pool. Under normal conditions, the top surface of the grid plate, the outer top surface of the fire extinguishing pool, and the ground of the parking space are flush.

[0007] Two movable seats that can move away from or move closer to each other are set between the perforated plate and the grid plate. Each movable seat is set along the width direction of the grid plate, and a spray pipe is rotatably connected to each movable seat via a rotating seat.

[0008] When the movable seat moves horizontally below the grating, the spray pipes are parallel to the movable seat; when the movable seat moves outside the grating, the spray pipes are perpendicular to the movable seat, and the two spray pipes are distributed at opposite corners on the left and right sides of the grating.

[0009] Optionally, a lifting mechanism is installed at the bottom of the fire extinguishing pool, and the end of the lifting mechanism is connected to a perforated plate.

[0010] Optionally, the top of the hollow plate is equipped with a horizontal moving mechanism corresponding to each moving seat, and each moving seat is connected to the end of the corresponding horizontal moving mechanism.

[0011] Optionally, the length of the perforated plate is greater than the length of the grid plate, and support plates are fixed on the front and rear sides of the perforated plate. Each support plate is arranged along the length direction of the perforated plate, and the grid plate is fixed to the top of the two support plates.

[0012] Optionally, a sliding rod is fixed to one end of the spray pipe near the rotating seat. The sliding rod is coaxially arranged with the spray pipe, and a groove adapted to the sliding rod is formed on the surface of the support plate.

[0013] Optionally, the chute includes short straight grooves, spiral grooves and long straight grooves distributed sequentially along the horizontal direction;

[0014] When the slide rod slides in the long straight groove, the spray pipe is parallel to the moving seat; when the slide rod slides along the long straight groove and the spiral groove to the short straight groove, the spray pipe is perpendicular to the moving seat.

[0015] Optionally, a plurality of first rotating sleeves are spaced apart along the axial direction of the spray pipe, and a first nozzle communicating with the spray pipe is fixed on each first rotating sleeve; a second rotating sleeve is provided between two adjacent first rotating sleeves and is fitted on the spray pipe, and a second nozzle communicating with the spray pipe is fixed on each second rotating sleeve, and each first rotating sleeve and each second rotating sleeve can rotate along the axis of the spray pipe.

[0016] Optionally, when the spray pipe is parallel to the movable seat, both the first nozzle and the second nozzle are inclined upwards, and the included angle between the first nozzle and the second nozzle is 80°-120°.

[0017] When the spray pipe is perpendicular to the movable seat, both the first nozzle and the second nozzle rotate to face the other spray pipe.

[0018] Optionally, the two ends of the first rotating sleeve are fixed with first positioning sleeves sleeved on the spray pipe, and a first positioning hole is opened in the circumferential direction on each first positioning sleeve, and a first positioning rod adapted to the first positioning hole is fixed on the spray pipe.

[0019] A second positioning sleeve is fixed at both ends of the second rotating sleeve and sleeved on the spray pipe. A second positioning hole is opened circumferentially on each second positioning sleeve. A second positioning rod adapted to the second positioning hole is fixed on the spray pipe. The length of the second positioning hole is less than the length of the first positioning hole.

[0020] Optionally, two first electromagnets are suspended at intervals around each first rotating sleeve, and each first electromagnet is fixed to the spray pipe by a bracket. A first permanent magnet located between the two first electromagnets is fixed on each first rotating sleeve.

[0021] Two second electromagnets are suspended at intervals around each second rotating sleeve. Each second electromagnet is fixed to the spray pipe by a bracket. A second permanent magnet is fixed on each second rotating sleeve between the two second electromagnets.

[0022] Compared with the prior art, the present invention provides an intelligent charging station for electric vehicles with automatic fire extinguishing function, which has the following beneficial effects:

[0023] 1. This invention, by setting up a fire extinguishing pool, a perforated plate, a grating plate, movable seats, and sprinkler pipes, ensures that under normal conditions, the top surface of the grating plate, the outer top surface of the fire extinguishing pool, and the ground of the parking space are flush, facilitating vehicle parking. Simultaneously, the two movable seats are close together, causing the sprinkler pipes to converge below the grating plate. In the event of a fire, the perforated plate moves downwards, pulling the burning vehicle into the fire extinguishing pool; at the same time, the two movable seats move away from each other, and water is sprayed directly onto the battery under the vehicle through sprinkler pipes parallel to the movable seats, effectively cooling and extinguishing the fire source immediately.

[0024] When the vehicle is fully submerged in the fire extinguishing tank, the water sprayed into the tank is sufficient to submerge the battery at the bottom of the vehicle, eliminating the need for further spraying of the battery. At this point, the spray pipes automatically rotate to be perpendicular to the moving base, with the two spray pipes positioned diagonally on either side of the grille, ensuring comprehensive water coverage of the space above the vehicle and guaranteeing the thoroughness and efficiency of the fire extinguishing operation.

[0025] 2. By setting up a first rotating sleeve, a first nozzle, a second rotating sleeve, and a second nozzle, when spraying water on the bottom of a vehicle, given the close distance between the spray pipe and the bottom of the vehicle, in order to ensure the spraying effect and coverage area, both the first nozzle and the second nozzle are in an upward angle, and the included angle between the first nozzle and the second nozzle is 80°-120°, thereby enabling better water spraying of the battery at the bottom of the vehicle and effectively suppressing fire sources.

[0026] When the sprinkler pipe is rotated to be perpendicular to the moving base, in order to avoid wasting water resources, the spray angles of the first and second nozzles need to be adjusted so that both the first and second nozzles rotate toward the other sprinkler pipe, thereby better covering the space above the electric vehicle. This allows for a more rational distribution and utilization of water flow at this stage, ensuring that the firefighting operation is both efficient and water-saving. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 8 An intelligent charging station for electric vehicles with automatic fire extinguishing function includes intelligent charging piles and a sunshade canopy, as well as a fire extinguishing pool 1, which is buried in the ground below the sunshade canopy. Fire monitoring equipment, such as smoke sensors, flame sensors, and thermal imaging cameras, is installed on the side of the sunshade canopy facing the fire extinguishing pool 1. Once a fire signal is detected, the system will respond quickly, promptly triggering subsequent fire extinguishing procedures and controlling the intelligent charging pile to cut off power.

[0038] To address the problem of existing technologies being unable to extinguish electric vehicle battery fires immediately, the following design is proposed:

[0039] The fire extinguishing pool 1 is equipped with a perforated plate 2 that can move up and down. In this embodiment, a lifting mechanism 6 is installed at the bottom of the fire extinguishing pool 1. The end of the lifting mechanism 6 is connected to the perforated plate 2, and the perforated plate 2 is moved up and down by the lifting mechanism 6. The lifting mechanism 6 can be a scissor-type hydraulic lift. A grid plate 3 that matches the opening of the fire extinguishing pool 1 is mounted on the top of the perforated plate 2 to seal the opening of the fire extinguishing pool 1. Under normal conditions, the top surface of the grid plate 3, the outer top surface of the fire extinguishing pool 1, and the ground of the parking space are flush, which facilitates the parking of electric vehicles.

[0040] Two movable seats 4 are arranged between the perforated plate 2 and the grid plate 3, which can move away from or towards each other. In this embodiment, a horizontal moving mechanism 7 corresponding to each movable seat 4 is installed on the top of the perforated plate 2, and each movable seat 4 is connected to the end of the corresponding horizontal moving mechanism 7. The horizontal moving mechanism 7 can be a linear module, which drives the movable seats 4 to move left and right to achieve the two movable seats 4 moving closer or further apart. Each movable seat 4 is arranged along the width direction of the grid plate 3, and a spray pipe 5 is rotatably connected to each movable seat 4 via a rotating seat. The spray pipe 5 can rotate along the rotating seat. It should be noted that the spray pipe 5 is connected to an external water source through a flexible hose, and the external water source consists of a water storage tank and a water pump.

[0041] When the movable seat 4 moves horizontally below the grille plate 3, the spray pipe 5 is parallel to the movable seat 4, which can spray water on the bottom of the electric vehicle. When the movable seat 4 moves outside the grille plate 3, the spray pipe 5 is perpendicular to the movable seat 4, and the two spray pipes 5 are distributed at the diagonal points on the left and right sides of the grille plate 3, which can spray water on the top of the electric vehicle.

[0042] Using the above structure, under normal conditions, the electric vehicle moves to the top of the grille plate 3 and charges using the charging pile. When a fire is detected, the lifting mechanism 6 moves the perforated plate 2 downwards, thereby moving the electric vehicle downwards. During this process, the horizontal moving mechanism 7 moves the two moving seats 4 away from each other, so that water is sprayed onto the bottom of the electric vehicle through the sprinkler pipes 5, cooling and extinguishing the battery at the bottom of the electric vehicle immediately. After the electric vehicle is completely placed into the fire extinguishing pool 1, the bottom of the electric vehicle can be submerged in water, and at the same time, the sprinkler pipes 5 are rotated to be perpendicular to the moving seats 4, so that the two sprinkler pipes 5 are distributed on the left and right diagonally on both sides of the grille plate 3, spraying water all over the space above the vehicle, suppressing the spread of fire to the greatest extent and ensuring the safety of the charging station and the surrounding environment.

[0043] The following describes how the spray pipe 5 rotates along the rotating base:

[0044] The length of the perforated plate 2 is greater than the length of the grid plate 3, which facilitates the rotation of the spray pipe 5 on the side of the grid plate 3. Support plates 8 are fixed on the front and rear sides of the perforated plate 2, and each support plate 8 is set along the length of the perforated plate 2. The grid plate 3 is fixed to the top of the two support plates 8 so that there is a certain gap between the grid plate 3 and the perforated plate 2 to accommodate the movable seat 4, the spray pipe 5 and other components.

[0045] A slide rod 9 is fixed to one end of the spray pipe 5 near the rotating seat. The slide rod 9 is coaxially arranged with the spray pipe 5, and a groove 10 adapted to the slide rod 9 is opened on the surface of the support plate 8. When the moving seat 4 moves left and right, it can drive the slide rod 9 to slide synchronously in the groove 10.

[0046] In this embodiment, the chute 10 includes a short straight chute 1001, a spiral chute 1002, and a long straight chute 1003 arranged sequentially in the horizontal direction. When the slide rod 9 slides in the long straight chute 1003, the spray pipe 5 is parallel to the movable seat 4; when the slide rod 9 slides along the long straight chute 1003 and the spiral chute 1002 into the short straight chute 1001, the spray pipe 5 is perpendicular to the movable seat 4.

[0047] With the above structure, when the movable seat 4 begins to move below the grille plate 3, the sliding rod 9 slides synchronously within the long straight groove 1003. Constrained by this mechanical structure, the spray pipe 5 remains horizontal and parallel to the movable seat 4, thus enabling water spraying operations on the bottom of the electric vehicle and effectively addressing potential battery fires. As the movable seat 4 continues to move outward, the sliding rod 9 slides into the spiral groove 1002. Due to the special spiral structure of the spiral groove 1002, the sliding rod 9 drives the spray pipe 5 to rotate around the rotating seat during its sliding within the groove. Until the sliding rod 9 reaches the short straight groove 1001, the spray pipe 5 has rotated to a vertical position, perpendicular to the movable seat 4, and at this time, the spray pipe 5 is precisely positioned outside the grille plate 3. This allows for water spraying operations on the space above the electric vehicle, comprehensively covering potential fire areas and further improving the comprehensiveness and efficiency of fire suppression.

[0048] During the research and development process, it was discovered that when the spray pipe 5 is in a horizontal position, given its relatively close proximity to the bottom of the vehicle, if the spray pipe 5 sprays water directly upwards, the water flow is limited by the short distance, resulting in a very limited spray range and making it difficult to fully cover the area under the vehicle that needs fire suppression. Furthermore, when the spray pipe 5 is in a vertical position, if its spray angle is not adjusted in time, most of the water cannot accurately reach the burning vehicle, leading to significant water waste. To properly address these technical challenges, the following design was developed:

[0049] A plurality of first rotating sleeves 11 are spaced apart along the axial direction of the spray pipe 5, and a first nozzle 12 communicating with the spray pipe 5 is fixed on each first rotating sleeve 11. In this embodiment, an annular groove is formed on the inner ring surface of the first rotating sleeve 11, and the first nozzle 12 communicates with the annular groove; a water outlet hole communicating with the annular groove is formed on the spray pipe 5, and a sealing ring is provided at the junction of the first rotating sleeve 11 and the spray pipe 5 to prevent water from overflowing. With this structure, the first nozzle 12 can always communicate with the spray pipe 5 when the first rotating sleeve 11 rotates on the spray pipe 5.

[0050] A second rotating sleeve 13 is provided between two adjacent first rotating sleeves 11 and sleeved on the spray pipe 5. A second nozzle 14 communicating with the spray pipe 5 is fixed on each second rotating sleeve 13. Each first rotating sleeve 11 and each second rotating sleeve 13 can rotate along the axis of the spray pipe 5. It should be noted that the structure of the second rotating sleeve 13 is the same as that of the first rotating sleeve 11, and the second nozzle 14 is always in communication with the spray pipe 5 in the same way.

[0051] When the spray pipe 5 is parallel to the movable seat 4, both the first nozzle 12 and the second nozzle 14 are in an upward angle, and the included angle between the first nozzle 12 and the second nozzle 14 is 80°-120°, which can ensure the spraying effect and sufficient coverage area, thereby enabling more efficient water spraying operations on the battery under the vehicle, effectively suppressing the fire source, reducing the fire risk, and improving the fire extinguishing efficiency.

[0052] When the spray pipe 5 is perpendicular to the movable base 4, both the first nozzle 12 and the second nozzle 14 rotate to face the other spray pipe 5. In this way, the water flow can accurately cover the burning vehicle, greatly reducing the ineffective spraying of water, avoiding a large waste of water resources, and ensuring that the water used for firefighting is used efficiently.

[0053] In this embodiment, first positioning sleeves 15, which are sleeved on the spray pipe 5, are fixed at both ends of the first rotating sleeve 11. First positioning holes 16 are provided circumferentially on each of the first positioning sleeves 15, and first positioning rods 17, corresponding to the first positioning holes 16, are fixed on the spray pipe 5. The cooperation between the first positioning sleeves 15 and the first positioning rods 17 prevents axial movement of the first rotating sleeve 11. Furthermore, the cooperation between the first positioning holes 16 and the first positioning rods 17 limits the rotation range of the first rotating sleeve 11.

[0054] Second positioning sleeves 18, fitted onto the spray pipes 5, are fixed at both ends of the second rotating sleeve 13. Each second positioning sleeve 18 has a second positioning hole 19 circumferentially formed. A second positioning rod 20, corresponding to the second positioning hole 19, is fixed on the spray pipe 5. The length of the second positioning hole 19 is less than the length of the first positioning hole 16. The cooperation of the second positioning sleeve 18 and the second positioning rod 20 prevents axial movement of the second rotating sleeve 13. Furthermore, the cooperation of the second positioning hole 19 and the second positioning rod 20 limits the rotation range of the second rotating sleeve 13. Because the length of the second positioning hole 19 is less than the length of the first positioning hole 16, the rotation range of the first rotating sleeve 11 is greater than that of the second rotating sleeve 13. Under normal conditions, this design ensures that the first nozzle 12 and the second nozzle 14 maintain a specific angle, guaranteeing effective coverage during water spraying operations under the vehicle. When the system triggers the rotation action, since the rotation range of the first rotating sleeve 11 and the second rotating sleeve 13 is different, when the second rotating sleeve 13 stops rotating, the first rotating sleeve 11 can continue to rotate until the angle between the first nozzle 12 and the second nozzle 14 is zero, and at the same time they are facing the other spray pipe 5, thereby achieving efficient and precise water spraying to extinguish the fire on the top of the burning vehicle and avoiding water waste.

[0055] It should be added that two first electromagnets 21 are suspended at intervals around each of the first rotating sleeves 11. Each first electromagnet 21 is fixed to the spray pipe 5 by a bracket. A first permanent magnet 22 is fixed on each first rotating sleeve 11 between the two first electromagnets 21. The magnetic poles of the two first electromagnets 21 are opposite. When the first rotating sleeve 11 needs to rotate, one of the first electromagnets 21 generates a repulsive force on the first permanent magnet 22, and the other first electromagnet 21 generates an attractive force on the first permanent magnet 22. The resultant force drives the first rotating sleeve 11 to rotate. To make the first rotating sleeve 11 rotate back, it is only necessary to change the current direction of the two first electromagnets 21. As the current direction changes, the magnetic pole direction of the two first electromagnets 21 also changes accordingly, thereby realizing the rotation of the first rotating sleeve 11.

[0056] Similarly, two second electromagnets 23 are suspended at intervals around each second rotating sleeve 13. Each second electromagnet 23 is fixed to the spray pipe 5 by a bracket. A second permanent magnet 24 is fixed on each second rotating sleeve 13 between the two second electromagnets 23. The rotation and turning principle of the second rotating sleeve 13 is the same as that of the first rotating sleeve 11, and will not be described again here.

[0057] With the above structure, when the spray pipe 5 is in a flat position and parallel to the movable seat 4, both the first nozzle 12 and the second nozzle 14 are in an upward angle, and the included angle between the first nozzle 12 and the second nozzle 14 is 80°-120°. This can more effectively spray water on the battery part at the bottom of the vehicle, quickly reduce the battery temperature, effectively suppress the fire source, and nip the fire hazard in the bud.

[0058] When the sprinkler pipe 5 rotates to a vertical position and is perpendicular to the movable base 4, one of the first electromagnets 21 generates a repulsive force against the first permanent magnet 22, and the other electromagnet 21 generates an attractive force against the first permanent magnet 22. The combined force drives the first rotating sleeve 11 to rotate until it reaches its limit. Simultaneously, one of the second electromagnets 23 generates a repulsive force against the second permanent magnet 24, and the other second electromagnet 23 generates an attractive force against the second permanent magnet 24. The combined force drives the second rotating sleeve 13 to rotate until it reaches its limit. At this point, the angle between the first nozzle 12 and the second nozzle 14 becomes zero, and both are pointing towards the other sprinkler pipe. In this way, the water flow can comprehensively and accurately cover the space above the electric vehicle, ensuring the fire extinguishing effect while minimizing water waste, and comprehensively ensuring that the fire extinguishing operation is carried out efficiently and water-savingly.

[0059] Additionally, it's important to note that the depth and capacity of fire extinguishing pool 1 directly affect the vehicle's submersion level and the effectiveness of fire suppression. Taking into account the height of common new energy vehicles, battery location, and the required submersion depth for fire suppression, fire extinguishing pool 1 is designed to be 5-6 meters long, 4-4 meters deep, and 4.5-5.5 meters deep. This ensures that after the vehicle is completely submerged in fire extinguishing pool 1, the water level covers the top of the vehicle, thereby providing comprehensive cooling for the battery and overall structure, effectively preventing the spread of fire.

[0060] Furthermore, both the first nozzle 12 and the second nozzle 14 are high-flow nozzles, with a single nozzle flow rate of 40-50 cubic meters per hour. Based on the standard volume of the fire extinguishing pool 1, these nozzles can fill the fire extinguishing pool 1 with water in a short time, approximately 5 minutes, to quickly immerse and extinguish the fire on the vehicle, effectively improving the fire extinguishing efficiency and maximizing the safety of the charging station and the vehicle.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
