Description

Technical Field

[0001] This invention relates to the field of safety facilities technology for new energy vehicles, specifically a fireproof, mobile, intelligent fire-extinguishing parking space for new energy vehicles. Background Technology

[0002] With the surge in the number of new energy vehicles, their unique fire safety issues are becoming increasingly prominent. New energy vehicles, especially pure electric vehicles, typically have their power battery packs located in the vehicle chassis. Due to factors such as cell aging, manufacturing defects, overcharging and over-discharging, and collisions, battery thermal runaway may occur, leading to fires. These fires are characterized by concealed fire sources (located in the chassis), intense combustion, extremely high temperatures, easy reignition, and the presence of large amounts of toxic and flammable gases.

[0003] The existing roof sprinkler systems commonly installed in parking lots and charging stations cannot effectively cover the battery packs under the vehicle chassis, and the water flow cannot directly reach the core area of ​​the fire source, resulting in low fire extinguishing efficiency. Once a vehicle catches fire, the high temperature and flames will quickly spread to surrounding vehicles, causing huge loss of life and property. Therefore, a fireproof, mobile, intelligent fire-extinguishing parking space for new energy vehicles is proposed. Summary of the Invention

[0015] Compared with existing technologies, this invention provides a fire-resistant, mobile, intelligent fire-extinguishing parking space for new energy vehicles, which has the following advantages: 1. This fire-resistant, mobile, intelligent fire-extinguishing parking space for new energy vehicles uses stainless steel nozzles surrounding both sides of the vehicle and hollow piercing needles inserted into the vehicle's battery pack to provide full-coverage cooling and fire extinguishing, effectively preventing the spread of fire and solving the problem of fires that are difficult to extinguish due to their concealed nature.

[0021] 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.

[0022] Example 1: Reference Figures 1-8 A fire-resistant, mobile, intelligent fire-extinguishing parking space for new energy vehicles includes a lower base plate 1 and an upper plate 2. The lower base plate 1 is welded with a thickness of 10mm and fixed to a concrete foundation with chemical bolts. The vehicle entrance / exit edge of the upper plate 2 has a steel ramp with a slope of 15° welded on it and coated with an anti-slip coating to facilitate vehicle entry. Rubber wheel stops are installed on both sides of the top of the upper plate 2 for limiting vehicle parking. The system also includes lightweight sliding rails 22, which are fixedly connected to the top sides of the lower base plate 1. Rubber wheel stops are also fixedly installed on the bottom sides of the upper plate 2. The upper plate 2 is equipped with multiple sets of movable pulleys 21, which are embedded in lightweight slide rails 22. The bottom of the upper plate 2 is provided with a translation mechanism that drives the upper plate 2 to slide along the lightweight slide rails 22. The fire extinguishing component is installed between the lower plate 1 and the upper plate 2. The fire extinguishing component is used to spray water to extinguish the fire from both sides of the bottom of the vehicle at a preset angle. The piercing component is located at the top center of the upper plate 2. The piercing component is used to vertically pierce into the battery pack from the bottom of the vehicle to extinguish the fire. The fire blocking component is located on both sides of the top of the upper plate 2. The fire blocking component is used to block the horizontal spray of the fire.

[0023] Reference Figures 1-4The translation mechanism includes a ball screw 3, which is rotatably connected to the bottom of the upper plate 2 via a mounting base. A stepper motor 31 is fixedly connected to the bottom of the upper plate 2. The output shaft of the stepper motor 31 is fixedly connected to the end of the ball screw 3 via a coupling. A translation sleeve 32 is threaded onto the ball screw 3. The bottom of the translation sleeve 32 is fixedly connected to the top of the lower base plate 1. When the stepper motor 31 receives a forward or reverse rotation signal, it drives the ball screw 3 to rotate, thereby driving the upper plate 2 to move forward or backward along the lightweight slide rail 22. The maximum stroke is 3 meters. A limit guide rod 33 is fixedly connected to the bottom of the upper plate 2. The limit guide rod 33 and the ball screw 3 are symmetrically arranged along the central axis of the upper plate 2. A guide slider 34 is slidably connected to the limit guide rod 33. The bottom of the guide slider 34 is fixedly connected to the top of the lower base plate 1.

[0024] With the above-mentioned mechanism, when a vehicle catches fire, the stepper motor 31 is started, which drives the ball screw 3 to rotate, causing the translational sleeve 32 to slide along the ball screw 3. This causes the upper plate 2 to move along the lightweight slide rail 22 in a preset open direction, thereby isolating the fire source from surrounding vehicles and facilities, effectively preventing fire chain reactions, protecting surrounding property, and improving safety in the fire area.

[0025] Reference Figures 1-4 The fire extinguishing assembly includes a water tank 4, which is fixedly connected to the bottom of the upper plate 2. A fire extinguishing agent tank 41 is fixedly connected to the bottom of the upper plate 2. The fire extinguishing agent tank 41 is filled with a fine water mist additive fire extinguishing agent composed of 3% fluorocarbon surfactant, 0.5% corrosion inhibitor, and deionized water. Multiple sets of stainless steel nozzles 42 are provided on both sides of the top of the upper plate 2, with three sets on each side, totaling six sets. The spray axis of the stainless steel nozzles 42 forms a 30° angle with the vertical direction, creating a cross-spray. The top of the upper plate 2 is fixedly connected to... The water supply pipe 43 and multiple sets of stainless steel nozzles 42 are connected to the water supply pipe 43 respectively. The input end of the water supply pipe 43 is connected to the inner cavity of the water storage tank 4. The bottom of the upper plate 2 is fixedly connected to a water pump 44, which is connected to the water supply pipe 43 and is used to drive the water flow along the stainless steel nozzles 42 for spraying. The water pump 44 is connected to the fire extinguishing agent tank 41 and the water supply pipe 43 through a proportioning mixer 45. The proportioning mixer 45 adopts existing mature technology, and its principle will not be described in detail. It achieves precise mixing of fire extinguishing agent and water at a ratio of 3:97.

[0026] With the above-mentioned mechanism in place, the water pump 44 is activated to draw water from the water storage tank 4 and deliver it to each set of stainless steel nozzles 42 through the water supply pipe 43. At the same time, with the proportioning mixer 45, the fire extinguisher in the fire extinguishing agent tank 41 is mixed with the fire extinguishing water in the appropriate proportion and finally sprayed along the multiple sets of stainless steel nozzles 42 towards the burning vehicle, providing full coverage cooling and fire extinguishing for the vehicle, effectively preventing the spread of fire and improving the fire extinguishing effect.

[0027] Reference Figure 7 A rotating ring 46 is rotatably connected to the water supply pipe 43. The rotating ring 46 is connected to the inner cavity of the water supply pipe 43, and multiple sets of stirring paddles 461 are fixedly connected to the inner wall of the rotating ring 46. The rotating ring 46 and the ball screw 3 are connected by a belt pulley set 462.

[0028] With the above-mentioned mechanism, when the ball screw 3 rotates and pushes the upper plate 2 to move as a whole, the transmission action of the pulley group 462 will drive the rotating ring 46 to rotate. At this time, in conjunction with the multiple sets of stirring paddles 461 set on its inner wall, the water and extinguishing agent passing through can be stirred, so that the two are effectively mixed and the extinguishing effect is ensured.

[0029] Reference Figure 5 , Figure 6 The puncture assembly includes an installation chamber 5, which is fixedly connected to the bottom of the upper plate 2. A puncture groove 51 is provided on the upper plate 2 located at the top of the installation chamber 5. A puncture screw 52 is rotatably connected inside the installation chamber 5. A drive motor 53 is fixedly connected to the bottom of the installation chamber 5. The output shaft of the drive motor 53 is fixedly connected to the bottom end of the puncture screw 52. A lifting ring 54 is threaded on the puncture screw 52 and fits against the inner wall of the installation chamber 5. A hollow puncture needle 55 is fixedly connected to the side wall of the lifting ring 54. The hollow puncture needle 55 is made of high-strength alloy steel, with a pyramidal tip and multiple micro-holes on the side wall. The central axis of the hollow puncture needle 55 coincides with that of the puncture groove 51. A first water pipe 56 is fixedly connected to and communicates with the side wall of the hollow puncture needle 55. The first water pipe 56 is connected to a water supply pipe 43 and is equipped with a solenoid valve.

[0030] With the above-mentioned mechanism, when the fire is intense (the temperature exceeds 150°C for 30 seconds), the drive motor 53 will be activated immediately, causing it to rotate the piercing screw 52. This causes the lifting ring 54 to move the hollow piercing needle 55 towards the bottom of the vehicle, eventually piercing the battery pack protective plate and penetrating deep into the battery module. The solenoid valve on the first water pipe 56 will then be activated, allowing high-pressure water mixed with extinguishing agent to flow directly into and spray onto the thermally runaway battery cells inside the battery pack. This achieves suffocation and cooling from the inside, solving the problem of fires that are hidden and difficult to extinguish, and greatly improving the efficiency of extinguishing deep fires.

[0031] Reference Figure 1 , Figure 2The top of the upper plate 2 is fixedly connected to a pole 57. A vertically downward fire extinguishing nozzle 571 is installed on the top of the pole 57. The fire extinguishing nozzle 571 is connected to the water supply pipe 43 through a second water pipe 572. A solenoid valve is installed in the second water pipe 572. A handheld fire extinguisher 58 is installed on the pole 57. The handheld fire extinguisher 58 is connected to the water supply pipe 43 through a third water pipe 581. A solenoid valve is installed in the third water pipe 581.

[0032] By setting up the aforementioned mechanism, the solenoid valve in the second water pipe 572 is opened, causing the fire extinguishing nozzle 571 to spray atomized water vertically downwards, forming a water mist that covers the roof of the vehicle. This cools any open flames and high-temperature components that may appear inside the vehicle, and effectively washes away and settles the toxic fumes produced by combustion, thereby further improving the fire extinguishing effect and ensuring the safety of the fire area. In addition, the solenoid valve in the third water pipe 581 can also be opened, allowing nearby personnel to use handheld fire extinguishers 58 to extinguish and cool the vehicle, thus achieving a comprehensive fire extinguishing effect from multiple directions, effectively preventing the spread of the fire and improving the fire extinguishing efficiency.

[0033] Reference Figures 1-3 and Figure 8 The fire-resistant assembly includes two sets of fireproof guide rails 6, which are fixedly installed on the top sides of the upper plate 2. A first hinge seat 61 is fixedly connected to one side of the inner cavity of the fireproof guide rail 6, and a second hinge seat 62 is slidably connected to the other side of the inner cavity of the fireproof guide rail 6. A fireproof spring 63 is fixedly connected between the first hinge seat 61 and the second hinge seat 62. A lifting rod 64 is rotatably connected inside both the first hinge seat 61 and the second hinge seat 62. The two sets of lifting rods 64 are arranged crosswise, and the middle parts of the two sets of lifting rods 64 are connected by a pin. The two sets of lifting rods 64 are rotatably connected to the top of a third hinge seat 641. The top of the third hinge seats 641 on both sides is fixedly connected to a lifting plate 642. The bottom of the lifting plate 642 is fixedly connected to the inner wall of the fireproof guide rail 6. A locking ring 621 is fixedly connected to the side wall of the second hinge seat 62. An electromagnetic lock 66 is fixedly connected to the bottom of the fireproof guide rail 6. The locking tongue of the electromagnetic lock 66 is inserted into the locking ring 621. Both the locking ring 621 and the locking tongue of the electromagnetic lock 66 are made of low melting point alloy material.

[0034] It should be noted that in the initial state, that is, when the fireproof curtain 65 is in the retracted state, the fireproof spring 63 is in the stretched state.

[0035] With the above-mentioned mechanism, when the vehicle catches fire, a blocking command is sent to the electromagnetic lock 66, causing the locking tongue of the electromagnetic lock 66 to disengage from the locking ring 621. Under the rebound action of the fireproof spring 63, the lifting plate 642 drives the fireproof curtain 65 to rise, thereby blocking both sides of the burning vehicle and effectively preventing the fire from spraying and spreading to nearby parking spaces. Since both the locking ring 621 and the locking tongue of the electromagnetic lock 66 are made of low-melting-point alloy materials, even if the signal is abnormal in the high-temperature environment of the fire, both will be melted by the high temperature, thus ensuring that the fireproof curtain 65 rises smoothly, achieving double insurance and effectively blocking the spread of fire.

[0036] In addition, to further prevent the fire from spreading, fire-blocking components can be added to the front and rear of the vehicle, thereby achieving more comprehensive fire interception.

[0037] Example 2: Reference Figure 9 Based on Embodiment 1, a control method for a fireproof, mobile, intelligent fire-extinguishing parking space for new energy vehicles is proposed. The method includes a PLC controller. Smoke detectors 7 are fixedly connected to both sides of the top of the upper plate 2. The smoke detectors 7 are electrically connected to the PLC controller. The PLC controller is electrically connected to the stepper motor 31, water pump 44, drive motor 53, electromagnetic lock 66, and each group of solenoid valves. The PLC controller is also electrically connected to the charging pile of the parking space. The PLC controller is equipped with a communication module for uploading data to a cloud monitoring platform.

[0038] When the temperature and smoke detector 7 detects a sudden temperature rise (threshold set at 80℃) and the smoke concentration exceeds the standard, it sends a fire alarm signal to the PLC controller. The PLC controller immediately executes the following instructions: Command 1: Send a command to the charging station to cut off the power supply to the charging gun, thus achieving a power outage linkage during charging. Command 2: Start water pump 44. The fire extinguishing system begins operation. The mixed extinguishing agent is sprayed upwards through six stainless steel nozzles 42, providing full-coverage cooling and fire extinguishing for the vehicle chassis. Command 3: Activate handheld fire extinguisher 58. Nearby personnel can use handheld fire extinguisher 58 to extinguish the fire and cool down the vehicle. Command 4: Start stepper motor 31 to drive the upper plate 2 and the burning vehicle on it to move steadily 3 meters in the preset open area at a speed of 0.1m / s, thereby isolating the fire source from the surrounding vehicles and facilities. Command 5: Send a blocking command to the electromagnetic lock 66, causing the locking tongue of the electromagnetic lock 66 to disengage from the locking ring 621. Under the rebound action of the fireproof spring 63, the lifting plate 642 drives the fireproof curtain 65 to rise, thereby blocking both sides of the burning vehicle and effectively preventing the fire from spraying and spreading to nearby parking spaces.

[0039] Command 6: The PLC controller will establish a connection with the cloud server through the communication module. The cloud server will then push real-time status updates to the management personnel's dedicated mobile app and the property fire control center. Normal status: The APP displays "Parking space is available, system is normal" or "Vehicle is charging, everything is normal"; Alarm status: When the smoke detector 7 is triggered, the APP will immediately receive a "fire alarm" push notification, accompanied by a strong vibration.

[0040] Status of the situation: The APP displays real-time statuses such as "Fire extinguishing system activated" and "Parking space is being moved".

[0041] Remote intervention: Managers can perform operations such as "remote confirmation", "manually start fire extinguishing" or "emergency relocation of parking spaces" through buttons on the APP.

[0042] Reference Figures 1-9 In this invention, during use, when the temperature and smoke detector 7 detects a sudden rise in temperature and excessive smoke concentration, it sends a fire alarm signal to the PLC controller. First, the PLC controller sends a command to the charging pile to cut off the power supply to the charging gun, achieving a charging power-off linkage. Then, the water pump 44 is started to draw water from the water storage tank 4 and deliver it along the water supply pipe 43 to each group of stainless steel nozzles 42. At the same time, in conjunction with the proportioning mixer 45, the fire extinguisher in the fire extinguishing agent tank 41 is mixed with the fire extinguishing water in the appropriate proportion, and finally, the mixture is distributed along the multi-stage fire extinguishing system. The stainless steel nozzles 42 spray towards the burning vehicle, providing full-coverage cooling and fire extinguishing, effectively preventing the spread of fire and improving the fire extinguishing effect. Simultaneously, while sending the fire alarm signal, the stepper motor 31 is started, causing it to drive the ball screw 3 to rotate. This causes the sliding sleeve 32 to slide along the ball screw 3, and the upper plate 2 to move along the lightweight slide rail 22 in a preset open direction, thereby isolating the fire source from surrounding vehicles and facilities, effectively preventing the fire chain reaction, protecting surrounding property, and improving the safety of the fire area.

[0043] When the fire becomes intense (temperature exceeding 150°C for 30 seconds), the drive motor 53 is immediately activated, causing it to rotate the piercing screw 52. This causes the lifting ring 54 to move the hollow piercing needle 55 towards the bottom of the vehicle, eventually piercing the battery pack protective plate and penetrating deep into the battery module. Simultaneously, the solenoid valve on the first water pipe 56 is activated, allowing high-pressure water mixed with extinguishing agent to flow directly onto the thermally runaway battery cells inside the battery pack. This achieves internal suffocation and cooling, solving the problem of concealed and difficult-to-extinguish fires and greatly improving the efficiency of extinguishing deep-seated fires. Simultaneously, the solenoid valve in the second water pipe 572 is opened, causing the fire extinguishing nozzle 571 to spray atomized water vertically downwards, forming a water mist that covers the roof of the vehicle. This cools any open flames and high-temperature components that may appear inside the vehicle and effectively washes away and settles toxic fumes produced during combustion, thereby further improving the fire extinguishing effect and ensuring the safety of the fire area. In addition, the solenoid valve in the third water pipe 581 can be opened at the same time, allowing nearby personnel to use handheld fire extinguishers 58 to extinguish and cool the vehicle, thus achieving a comprehensive fire extinguishing effect from multiple directions, effectively preventing the spread of the fire and improving the fire extinguishing efficiency.

[0044] In addition, while the PLC controller sends a fire alarm signal, it will send a blocking command to the electromagnetic lock 66, causing the locking tongue of the electromagnetic lock 66 to disengage from the locking ring 621. Under the rebound action of the fireproof spring 63, the lifting plate 642 drives the fireproof curtain 65 to rise, thereby blocking the two sides of the burning vehicle and effectively preventing the fire from spraying and spreading to the adjacent parking space.
