Description

Technical Field

[0001] The present invention relates to the technical field of vehicle power supply, and particularly to an intelligent charging station for electric vehicles with an automatic fire extinguishing function. Background Art

[0002] An intelligent charging station for electric vehicles is a facility for providing charging services for electric vehicles, which integrates intelligent control, communication technology, power electronics technology, etc. With the continuous increase in the ownership of electric vehicles, the construction of intelligent charging stations for electric vehicles is also constantly developing and improving.

[0003] In existing intelligent charging stations for electric vehicles, in order to effectively prevent electric vehicles from catching fire during the charging process and avoid the fire from spreading to surrounding facilities and vehicles, specific pits are usually set under the parking spaces. For example, the patent with the publication number CN221315864U discloses an intelligent prevention and control platform for electric vehicle charging pile fires in different regions. This regional prevention and control platform for electric vehicle charging piles is provided with explosion-proof fire pits under each charging parking space, and is equipped with a lifting structure and a fire sprinkler structure. After a fire occurs in a certain charging parking space, the vehicle on fire is lowered into the explosion-proof fire pit, and then water is sprayed on the top of the vehicle on fire until the vehicle is completely soaked in water, so as to achieve efficient fire extinguishing.

[0004] It is found in actual use that the root cause of electric vehicle fires is mostly battery failure. In the prior art, water is directly sprayed on the top of the vehicle, and it is difficult for the water to quickly penetrate to the battery part at the bottom of the vehicle, and it is impossible to effectively cool and extinguish the fire source at the first time. This results in that in the initial stage of the fire, the fire is difficult to be effectively controlled, and the golden opportunity for fire extinguishing is missed, greatly increasing the risk of fire spread. For this reason, we propose an intelligent charging station for electric vehicles with an automatic fire extinguishing function to well solve the above disadvantages. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent charging station for electric vehicles with an automatic fire extinguishing function, which is used to solve the problem in the prior art that the battery of an electric vehicle cannot be extinguished in the first time as mentioned in the above background art.

[0006] The present invention is achieved through the following technical solutions: An intelligent charging station for electric vehicles with an automatic fire extinguishing function includes an intelligent charging pile and a sunshade canopy, and also includes a fire extinguishing pool. The fire extinguishing pool is buried in the ground under the sunshade canopy. A hollow plate capable of moving up and down is arranged in the fire extinguishing pool, and a grille plate adapted to the pool opening of the fire extinguishing pool is erected on the top of the hollow plate; in the normal state, the top surface of the grille plate, the outer top surface of the fire extinguishing pool and the ground of the parking space are flush.

[0007] There are two movable seats that can move away from or close to each other between the hollow plate and the grille plate. Each movable seat is arranged along the width direction of the grille plate, and a spray pipe is rotatably connected to each movable seat through a rotating seat;

[0008] When the movable seat moves horizontally below the grille plate, the spray pipe is parallel to the movable seat; when the movable seat moves outside the grille plate, the spray pipe is perpendicular to the movable seat, and the two spray pipes are distributed at the diagonals on the left and right sides of the grille plate.

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

[0010] Optionally, a horizontal moving mechanism corresponding to each movable seat is installed on the top of the hollow plate, and each movable seat is respectively connected to the end of the corresponding horizontal moving mechanism.

[0011] Optionally, the length of the hollow plate is greater than the length of the grille plate. Support plates are fixed on the front and rear sides of the hollow plate. Each support plate is arranged along the length direction of the hollow plate, and the grille plate is fixed on the tops of the two support plates.

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

[0013] Optionally, the chute includes a short straight groove, a spiral groove, and a long straight groove that are sequentially distributed in the horizontal direction;

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

[0015] Optionally, a number of first rotating sleeves are sleeved on the spray pipe at intervals along its axial direction. A first nozzle communicated with the spray pipe is fixed on each first rotating sleeve; a second rotating sleeve sleeved on the spray pipe is arranged between two adjacent first rotating sleeves. A second nozzle communicated 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 in an obliquely upward state, 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, first positioning sleeves sleeved on the spray pipe are fixed at both ends of the first rotating sleeve. First positioning holes are circumferentially formed in each first positioning sleeve, and first positioning rods adapted to the first positioning holes are fixed on the spray pipe.

[0019] Second positioning sleeves sleeved on the spray pipe are fixed at both ends of the second rotating sleeve. Second positioning holes are circumferentially formed in each second positioning sleeve, and second positioning rods adapted to the second positioning holes are fixed on the spray pipe. The length of the second positioning hole is less than that of the first positioning hole.

[0020] Optionally, two first electromagnets are suspended at intervals on the periphery of each first rotating sleeve. Each first electromagnet is fixed to the spray pipe through a bracket, and 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 on the periphery of each second rotating sleeve. Each second electromagnet is fixed to the spray pipe through a bracket, and a second permanent magnet located between the two second electromagnets is fixed on each second rotating sleeve.

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

[0023] 1. By providing a fire extinguishing pool, a hollow plate, a grid plate, a moving seat and a spray pipe, in a normal state, 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, facilitating vehicle parking. At the same time, the two moving seats approach each other, causing each spray pipe to be retracted below the grid plate. When a fire occurs, the hollow plate moves downward, driving the burning vehicle into the fire extinguishing pool. At the same time, the two moving seats move away from each other, and the spray pipe parallel to the moving seat directly sprays water on the battery at the bottom of the vehicle, effectively cooling and extinguishing the fire source in the first time.

[0024] When the vehicle is completely received into the fire extinguishing pool, the accumulated water sprayed on the battery in the fire extinguishing pool can soak the battery at the bottom of the vehicle, so there is no need to spray water on the battery anymore. At this time, the spray pipe automatically rotates to be perpendicular to the moving seat, and the two spray pipes are distributed at the diagonal positions on the left and right sides of the grid plate, so as to be able to spray water on the space above the car in all directions, ensuring the comprehensiveness and high efficiency of the fire extinguishing operation.

[0025] 2. By providing a first rotating sleeve, a first nozzle, a second rotating sleeve and a second nozzle, when performing a water spraying operation on the bottom of a vehicle, considering that the distance between the spray pipe and the bottom of the vehicle is relatively close, to ensure the spraying effect and coverage area, at this time both the first nozzle and the second nozzle are in an obliquely upward state, and the included angle between the first nozzle and the second nozzle is 80°-120°, so that the battery at the bottom of the vehicle can be better sprayed with water, effectively containing the fire source.

[0026] When the spray pipe rotates to be perpendicular to the moving seat, to avoid waste of water resources, it is necessary to adjust the spraying angles of the first nozzle and the second nozzle so that both the first nozzle and the second nozzle rotate to face the other spray pipe, so as to better cover the upper space of the electric vehicle, and then make the water flow achieve more reasonable distribution and utilization at this stage, fully ensuring that the fire extinguishing operation is both efficient and water-saving.

Specific implementation mode

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 to 8 , an intelligent charging station for electric vehicles with an automatic fire extinguishing function, including an intelligent charging pile and a sunshade canopy, further including a fire extinguishing pool 1, and the fire extinguishing pool 1 is buried in the ground below the sunshade canopy. On one side of the sunshade canopy facing the fire extinguishing pool 1, fire monitoring devices are installed, such as smoke sensors, flame sensors, and thermal imaging cameras, etc. Once a fire signal is detected, the system will quickly respond, trigger the subsequent fire extinguishing process in a timely manner, and control the intelligent charging pile to cut off the power.

[0038] In order to solve the problem that the battery of an electric vehicle cannot be extinguished in the first time in the prior art, the following design is specifically carried out:

[0039] A hollow plate 2 capable of moving up and down is arranged in the fire extinguishing pool 1. In this embodiment, a lifting mechanism 6 is installed at the inner bottom of the fire extinguishing pool 1, and the end of the lifting mechanism 6 is connected to the hollow plate 2, and the hollow plate 2 is driven to move up and down by the lifting mechanism 6; the lifting mechanism 6 can adopt a scissor hydraulic lift. A grille plate 3 adapted to the pool mouth of the fire extinguishing pool 1 is erected on the top of the hollow plate 2 for blocking the pool mouth of the fire extinguishing pool 1; in the normal state, the top surface of the grille plate 3, the outer top surface of the fire extinguishing pool 1 and the ground of the parking space are flush, which is convenient for the parking of electric vehicles.

[0040] There are two moving seats 4 that can move away from or close to each other between the hollow plate 2 and the grille plate 3. In this embodiment, a horizontal moving mechanism 7 corresponding to each moving seat 4 is installed on the top of the hollow plate 2, and each moving seat 4 is respectively connected to the end of the corresponding horizontal moving mechanism 7; the horizontal moving mechanism 7 can adopt a linear module, and the linear module drives the moving seat 4 to move left and right, so as to realize the mutual approach or separation of the two moving seats 4. Each moving seat 4 is arranged along the width direction of the grille plate 3, and a spray pipe 5 is rotatably connected to each moving seat 4 through a rotating seat, and 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 hose, and the external water source consists of a water storage tank and a water pump.

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

[0042] With the above structure, in the normal state, the electric vehicle moves to directly above the grille plate 3 and is charged using a charging pile. When a fire is detected, the lifting mechanism 6 drives the hollow plate 2 to move downward, thereby driving the electric vehicle to move downward. During this process, the horizontal moving mechanism 7 drives the two moving seats 4 to move away from each other, so as to spray water on the bottom of the electric vehicle through the spray pipe 5, cooling and extinguishing the battery at the bottom of the electric vehicle in the first time. When the electric vehicle is completely received into the fire extinguishing pool 1, the bottom of the electric vehicle can be soaked by the accumulated water, and at the same time, the spray pipe 5 is rotated to be perpendicular to the moving seat 4, so that the two spray pipes 5 are distributed at the diagonals on the left and right sides of the grille plate 3, spraying water on the upper space of the vehicle comprehensively, and curbing the spread of the fire to the greatest extent to ensure the safety of the charging station and the surrounding environment.

[0043] The following introduces how the spray pipe 5 rotates along the rotating seat:

[0044] The length of the hollow plate 2 is greater than the length of the grille plate 3, which is convenient for the spray pipe 5 to flip on the side of the grille plate 3. Support plates 8 are fixed on the front and rear sides of the hollow plate 2, and each support plate 8 is arranged along the length direction of the hollow plate 2. The grille plate 3 is fixed on the top of the two support plates 8, so that there is a certain gap between the grille plate 3 and the hollow plate 2 to accommodate components such as the moving seat 4 and the spray pipe 5.

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

[0046] In this embodiment, the chute 10 includes a short straight groove 1001, a spiral groove 1002, and a long straight groove 1003 that are sequentially distributed in the horizontal direction. When the sliding rod 9 slides in the long straight groove 1003, the spray pipe 5 is parallel to the moving seat 4; when the sliding rod 9 slides from the long straight groove 1003 and the spiral groove 1002 into the short straight groove 1001, the spray pipe 5 is perpendicular to the moving seat 4.

[0047] With the above structure, when the moving seat 4 starts to move below the grille plate 3, the sliding rod 9 synchronously slides in the long straight groove 1003. Constrained by this mechanical structure, the spray pipe 5 always maintains a flat posture and is parallel to the moving seat 4, so that the bottom of the electric vehicle can be sprayed with water to effectively cope with possible situations such as battery fires. As the moving seat 4 continues to move outwards, the sliding rod 9 slides into the spiral groove 1002 accordingly. Due to the special spiral structure of the spiral groove 1002, during the sliding process of the sliding rod 9 in this groove, the spray pipe 5 will be driven to rotate around the rotating seat. When the sliding rod 9 reaches the short straight groove 1001, the spray pipe 5 has rotated to the vertical state and is perpendicular to the moving seat 4. At this time, the spray pipe 5 is exactly located outside the grille plate 3, so that the space above the electric vehicle can be sprayed with water, covering the possible fire areas in all directions and further improving the comprehensiveness and efficiency of fire extinguishing.

[0048] During the R & D process, it is found that when the spray pipe 5 is in a flat state, due to its relatively close distance from the bottom of the vehicle, if the spray pipe 5 sprays water directly upwards at this time, the water flow is limited by the short-distance space, and the spraying range is extremely limited, making it difficult to comprehensively cover the area to be extinguished at the bottom of the vehicle. In addition, when the spray pipe 5 is in the vertical state, if the spraying angle is not adjusted in time, most of the water source cannot accurately act on the vehicle on fire, resulting in serious waste of water resources. To properly solve the above technical pain points, the following design is specifically carried out:

[0049] A number of first rotating sleeves 11 are sleeved on the spray pipe 5 at intervals along its axial direction, and a first nozzle 12 communicated 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, when the first rotating sleeve 11 rotates on the spray pipe 5, the first nozzle 12 can always communicate with the spray pipe 5.

[0050] A second rotating sleeve 13 sleeved on the spray pipe 5 is arranged between two adjacent first rotating sleeves 11. A second nozzle 14 communicated 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 communicated with the spray pipe 5 in the same way.

[0051] When the spray pipe 5 is parallel to the moving seat 4, both the first nozzle 12 and the second nozzle 14 are in an obliquely upward state, 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, so as to be able to more efficiently perform the water spraying operation on the battery at the bottom of the vehicle, effectively contain the fire source, reduce the fire risk, and improve the fire extinguishing efficiency.

[0052] When the spray pipe 5 is perpendicular to the moving seat 4, both the first nozzle 12 and the second nozzle 14 rotate to face another spray pipe 5. In this way, the water flow can accurately cover the vehicle on fire, greatly reducing the ineffective spraying of water source, avoiding a large amount of waste of water resources, and ensuring the efficient use of fire extinguishing water.

[0053] In this embodiment, first positioning sleeves 15 sleeved on the spray pipe 5 are fixed at both ends of the first rotating sleeve 11. First positioning holes 16 are circumferentially formed in each first positioning sleeve 15, and first positioning rods 17 adapted to the first positioning holes 16 are fixed on the spray pipe 5. Through the cooperation of the first positioning sleeve 15 and the first positioning rod 17, the axial movement of the first rotating sleeve 11 can be prevented. Moreover, through the cooperation of the first positioning hole 16 and the first positioning rod 17, the rotation range of the first rotating sleeve 11 can be restricted.

[0054] At both ends of the second rotating sleeve 13, second positioning sleeves 18 sleeved on the spray pipe 5 are fixed. Second positioning holes 19 are circumferentially formed in each second positioning sleeve 18. A second positioning rod 20 adapted to the second positioning holes 19 is fixed on the spray pipe 5. The length of the second positioning holes 19 is less than that of the first positioning holes 16. Through the cooperation of the second positioning sleeves 18 and the second positioning rods 20, axial movement of the second rotating sleeve 13 can be prevented. Moreover, through the cooperation of the second positioning holes 19 and the second positioning rods 20, the rotation range of the second rotating sleeve 13 can be restricted. Since the length of the second positioning holes 19 is less than that of the first positioning holes 16, the rotation range of the first rotating sleeve 11 is greater than that of the second rotating sleeve 13. In a normal state, this design can ensure that the first nozzle 12 and the second nozzle 14 maintain a specific angle, guaranteeing the coverage effect during the water spraying operation on the vehicle bottom. When the system triggers the rotation action, due to the different rotation ranges of the first rotating sleeve 11 and the second rotating sleeve 13, 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 they simultaneously face another spray pipe 5, thereby achieving efficient and precise water spraying and fire extinguishing on the top of the burning vehicle and avoiding waste of water sources.

[0055] It should be added that two first electromagnets 21 are suspended at intervals on the periphery of each first rotating sleeve 11. Each first electromagnet 21 is fixed to the spray pipe 5 through a bracket. A first permanent magnet 22 located between the two first electromagnets 21 is fixed on each first rotating sleeve 11. The magnetic pole directions of the two first electromagnets 21 are opposite. When it is necessary to rotate the first rotating sleeve 11, 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 generated thereby drives the first rotating sleeve 11 to rotate. If it is necessary to rotate the first rotating sleeve 11 in the reverse direction, only the current directions of the two first electromagnets 21 need to be changed. With the change of the current directions, the magnetic pole directions of the two first electromagnets 21 also change accordingly, thereby realizing the reverse rotation action of the first rotating sleeve 11.

[0056] Similarly, two second electromagnets 23 are suspended at intervals on the periphery of each second rotating sleeve 13. Each second electromagnet 23 is fixed to the spray pipe 5 through a bracket. A second permanent magnet 24 located between the two second electromagnets 23 is fixed on each second rotating sleeve 13. The rotation and reverse rotation principles of the second rotating sleeve 13 are the same as those of the first rotating sleeve 11 and will not be elaborated here.

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

[0058] When the spray pipe 5 rotates to a vertical state and is perpendicular to the moving seat 4, one of the first electromagnets 21 generates a repulsive force on the first permanent magnet 22, and the other electromagnet 21 generates an attractive force on the first permanent magnet 22. The resultant force generated thereby drives the first rotating sleeve 11 to rotate until it reaches the limit position; at the same time, one of the second electromagnets 23 generates a repulsive force on the second permanent magnet 24, and the other second electromagnet 23 generates an attractive force on the second permanent magnet 24. The resultant force generated thereby drives the second rotating sleeve 13 to rotate until it reaches the limit position; at this time, the included angle between the first nozzle 12 and the second nozzle 14 becomes zero, and both of them are simultaneously directed towards the direction of the other spray pipe. In this way, the water flow can comprehensively and accurately cover the upper space of the electric vehicle, while ensuring the fire extinguishing effect, minimizing the waste of water resources, and comprehensively ensuring the efficient and water-saving development of the fire extinguishing operation.

[0059] In addition, it should be added that the depth and capacity of the fire extinguishing pool 1 are directly related to the immersion degree of the vehicle and the fire extinguishing effect. Considering the height of common new energy vehicles, the battery position, and the immersion depth required for fire extinguishing comprehensively, the length of the fire extinguishing pool 1 is in the range of 5 - 6 meters, the width is in the range of 4 - 4 meters, and the depth is in the range of 4.5 - 5.5 meters. Ensure that after the vehicle completely falls into the fire extinguishing pool 1, the water surface can submerge the top of the vehicle, so as to cool the vehicle battery and the overall structure comprehensively and effectively block the spread of the fire.

[0060] Moreover, both the first nozzle 12 and the second nozzle 14 are selected as large-flow nozzles, and the flow rate of a single nozzle can reach 40 - 50 cubic meters per hour. Calculated based on the standard volume of the fire extinguishing pool 1, these nozzles can fill the fire extinguishing pool 1 with water in a relatively short time, about 5 minutes, quickly achieve the soaking fire extinguishing of the vehicle, effectively improve the fire extinguishing efficiency, and maximize the safety of the charging station and the vehicle.

Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

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