Description

Technical Field

[0001] This invention relates to the field of automatic fire protection technology for electric vehicle sheds, and specifically to an automatic fire protection facility specifically designed to extinguish fires in electric vehicle sheds. Background Technology

[0002] With the increasing popularity of electric vehicles, centralized charging facilities and electric vehicle sheds are widely used in residential communities, commercial areas, and public parking areas.

[0003] Some problems still exist with the above technologies:

[0004] During charging and parking, the batteries, electrical connection components, and charging equipment of electric vehicles are in operation for extended periods. If wiring aging, battery thermal runaway, or abnormally high ambient temperatures occur, localized overheating or even fire can easily develop. Because electric vehicle sheds are typically semi-open structures with good ventilation, once a fire starts, the continuous influx of air will intensify the combustion process, increasing the risk of fire spread and posing a safety hazard to surrounding vehicles and personnel.

[0005] Existing fire-fighting methods for electric vehicle sheds mainly rely on fixed fire nozzles or manual fire extinguishing devices. In actual use, these devices often have problems such as fixed fire extinguishing range, delayed response, and insufficient adaptability to the location of the fire. When the fire source is located under the vehicle, in the battery area, or in a part of the shed, the fixed spray direction is difficult to aim at the core area of ​​the fire source, resulting in reduced fire extinguishing efficiency. At the same time, manual intervention has shortcomings such as long response time and high risk of personnel approaching the fire source in the event of a sudden fire.

[0006] Furthermore, most existing electric vehicle sheds lack a safety control structure linked to the charging equipment. In the event of a fire, they may continue charging, and the power supply may not be cut off in time, potentially causing continuous discharge or secondary short circuits, exacerbating the fire and further increasing the difficulty of firefighting. On the other hand, some fire-fighting structures fail to effectively seal the shed space when extinguishing fires, allowing extinguishing agents to easily leak out. This not only wastes resources but also makes it difficult to create a stable fire-fighting environment in a short time, posing a risk of reignition. Summary of the Invention

[0007] Therefore, the present invention provides an automatic fire-fighting facility specifically designed for extinguishing fires in electric vehicle sheds, in order to solve the problems of slow fire response and low fire-extinguishing efficiency in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] An automatic fire-fighting facility specifically designed for extinguishing fires in electric vehicle sheds includes a base, with the top of the base connected to the shed body, both sides of the shed body having a sealing mechanism, and the middle of the base having an automatic fire-extinguishing mechanism.

[0010] The automatic fire extinguishing mechanism includes a drive motor, a lead screw, a sliding support, a moving frame, an inert gas injector, a delivery pipe, and a fire extinguishing nozzle. The output end of the drive motor is fixedly connected to the lead screw, the middle of the lead screw is threadedly connected to the sliding support, the top of the sliding support is fixedly connected to the moving frame, the inner side of the moving frame is fixedly connected to the delivery pipe, the inner side of the delivery pipe is fixedly connected to the fire extinguishing nozzle, and the top of the sliding support is fixedly connected to a heat source sensor.

[0011] The closing mechanism includes a dual-axis motor, winding wheels, connecting ropes, limiting rods, adjusting rods, and closing blades. The two output ends of the dual-axis motor are fixedly connected to winding wheels. Two connecting ropes are fixedly connected to the outer sides of the two winding wheels. Adjusting rods are fixedly connected to the bottom ends of the two connecting ropes. The adjusting rods are connected to the closing blades.

[0012] Furthermore: a guide rail is fixedly connected to the inner side of the base, the bottom end of the sliding support is slidably connected to the top end of the guide rail, the transmission motor is fixedly connected to the inner side of the base, and one end of the lead screw is rotatably connected to the inner side of the base.

[0013] Furthermore: a charging pile is fixedly connected to one side of the top of the base, and two elevation platforms are fixedly connected to the middle of the top of the base.

[0014] Furthermore: a power cut-off device is fixedly connected to the top of the charging pile, and a distributed smoke detector is fixedly connected to the inner side of the carport body. The distributed smoke detector is electrically connected to the charging pile through the power cut-off device.

[0015] Furthermore: a transfer pump is fixedly connected to the back side of the base, a connecting pipe is fixedly connected to the inlet end of the transfer pump, an installation pipe is fixedly connected to the outlet end of the transfer pump, and one end of the installation pipe is fixedly connected to the delivery pipe.

[0016] Furthermore: an inert gas injector is fixedly connected to the top of the movable frame, the inert gas injector is electrically connected to the transfer pump, the transfer pump is electrically connected to the drive motor, and the drive motor is electrically connected to the distributed smoke detector.

[0017] Furthermore: a filter screen is snapped onto the top of the carport body, transmission pipes are fixedly connected to both sides of the carport body, an electric valve is connected to the middle of each of the two transmission pipes, and a cooling nozzle is fixedly connected to the outer side of each of the two transmission pipes.

[0018] Furthermore: mounting frames are fixedly connected to both sides of the bottom end of the carport body, and the dual-axis motor is fixedly connected to the inner side of the mounting frame.

[0019] Furthermore: a limiting rod is fixedly connected to the bottom end of the mounting bracket, the bottom end of the limiting rod penetrates through the closed blade, and one end of the cooling nozzle is placed on the outside of the closed blade.

[0020] Furthermore, the drive motor is electrically connected to the dual-shaft motor.

[0021] The present invention has the following advantages:

[0022] 1. This device, by setting an automatic fire extinguishing mechanism in the middle of the base, and in conjunction with the cooperation between the drive motor, lead screw, sliding support and guide rail, enables the moving frame to move in a controllable linear motion along the bottom of the carport body. This drives the delivery pipe and fire extinguishing nozzle to accurately position and spray the fire source area, avoiding the problems of limited coverage and low fire extinguishing efficiency of traditional fixed fire extinguishing nozzles. At the same time, under the real-time monitoring of the heat source sensor, the sliding support can automatically stop in the high-temperature concentrated area, so that the fire extinguishing medium output by the inert gas injector can be concentrated on the core of the fire. This not only shortens the fire extinguishing response time, but also effectively reduces the amount of inert gas used, improves the fire extinguishing targeting and resource utilization, and enhances the active protection capability of the electric vehicle carport in the event of sudden situations such as battery thermal runaway.

[0023] 2. By installing a sealing mechanism consisting of a dual-axis motor, a winding wheel, a connecting rope, an adjusting rod, a limiting rod, and sealing blades on both sides of the carport body, this device can simultaneously complete the spatial sealing operation in the event of a fire. The dual-axis motor drives the winding wheel to wind up the connecting rope, causing the sealing blades to close quickly under the guidance and constraint of the limiting rod, thereby creating a relatively sealed fire extinguishing environment inside the carport body. This effectively suppresses the risk of reignition caused by the continuous entry of outside air, while reducing the decrease in fire extinguishing efficiency caused by the outward diffusion of inert gas. Combined with the stable support of the mounting frame for the dual-axis motor, the sealing action is reliable and controllable, significantly improving the safety and stability of the entire electric vehicle carport during the fire extinguishing process.

[0024] 3. This device achieves automated control of fire detection, power cut-off, fire extinguishing activation, and structural linkage through the electrical connection between distributed smoke detectors, power cut-off devices, transfer pumps, and drive motors. Upon detecting smoke or abnormal operating conditions, it can immediately cut off the power supply to the charging pile, reducing the risk of fire spread due to continuous electrical discharge. Simultaneously, it drives the transfer pump to deliver the extinguishing medium to the fire extinguishing nozzles via connecting pipes, installation pipes, and delivery pipes. In conjunction with the filter screen on the top of the carport body, as well as the transfer pipes on both sides, cooling nozzles, and electric valves, it filters smoke and dust inside and outside the carport and cools the structure. Thus, while extinguishing the fire, it also takes into account environmental safety and structural protection, improving the overall reliability and practical value of the electric vehicle carport fire protection facilities.

Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. It should be understood that these embodiments are merely for further explanation of the present invention and should not be construed as limiting the scope of protection of the present invention. Technical engineers in the field can make some non-essential improvements and adjustments to the present invention based on the above-described content. 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.

[0036] Please see Figures 1-6 An automatic fire-fighting facility specifically designed to extinguish fires in electric vehicle sheds includes a base 1, with a car shed body 2 connected to the top of the base 1. Both sides of the car shed body 2 are equipped with a closing mechanism 3, and an automatic fire-extinguishing mechanism 4 is provided in the middle of the base 1.

[0037] The automatic fire extinguishing mechanism 4 includes a drive motor 403, a lead screw 410, a sliding support 409, a moving frame 404, an inert gas injector 412, a delivery pipe 406, and a fire extinguishing nozzle 405. The output end of the drive motor 403 is fixedly connected to the lead screw 410. The middle part of the lead screw 410 is threadedly connected to the sliding support 409. The top end of the sliding support 409 is fixedly connected to the moving frame 404. The inner side of the moving frame 404 is fixedly connected to the delivery pipe 406. The inner side of the delivery pipe 406 is fixedly connected to the fire extinguishing nozzle 405. The top end of the sliding support 409 is fixedly connected to a heat source sensor 408.

[0038] The closing mechanism 3 includes a dual-axis motor 307, a winding wheel 308, a connecting rope 309, a limiting rod 310, an adjusting rod 311, and a closing blade 305. The two output ends of the dual-axis motor 307 are fixedly connected to the winding wheel 308. The outer sides of the two winding wheels 308 are fixedly connected to two connecting ropes 309. The bottom ends of the two connecting ropes 309 are fixedly connected to the adjusting rod 311, which is connected to the closing blade 305.

[0039] In the above components, the device uses the base 1 as the overall installation and support foundation during use. The carport body 2 is set on the top of the base 1 to cover electric vehicles and form a protective space. When an abnormal working condition occurs, the automatic fire extinguishing mechanism 4 is activated in the middle of the base 1. The drive motor 403 drives the lead screw 410 to rotate, causing the sliding support 409 to drive the moving frame 404 to move in a predetermined direction. The delivery pipe 406 delivers inert gas to the fire extinguishing nozzle 405 for spraying. At the same time, the sealing mechanism 3 controls the sealing blade 305 to move under the drive of the dual-axis motor 307, sealing both sides of the carport body 2 to complete the construction of the fire extinguishing environment.

[0040] A guide rail 411 is fixedly connected to the inner side of the base 1. The bottom end of the sliding support 409 is slidably connected to the top end of the guide rail 411. The drive motor 403 is fixedly connected to the inner side of the base 1. One end of the lead screw 410 is rotatably connected to the inner side of the base 1.

[0041] In the above components, during the operation of the automatic fire extinguishing mechanism 4, the drive motor 403 is fixed to the inner side of the base 1 and outputs rotational power to the lead screw 410. The lead screw 410 forms a threaded transmission relationship with the sliding support 409 in the rotating state. The bottom end of the sliding support 409 slides stably along the top end of the guide rail 411 under the constraint of the guide rail 411, so that the sliding support 409 and the moving frame 404 above it maintain a straight running state, thereby ensuring that the delivery pipe 406 and the fire extinguishing nozzle 405 do not deviate during the movement, and improving the controllability and stability of the fire extinguishing spray position.

[0042] A charging pile 6 is fixedly connected to one side of the top of the base 1, and two raising platforms 5 are fixedly connected to the middle of the top of the base 1.

[0043] In the above components, the charging pile 6 set on one side of the top of the base 1 is used to provide a charging interface for electric vehicles. The two raising platforms 5 set in the middle of the top of the base 1 are used to limit and raise the vehicle parking position, so that the bottom of the vehicle and the automatic fire extinguishing mechanism 4 are kept at a reasonable distance. In the event of a fire, it will not affect the movement of the sliding support 409 and the moving frame 404, and it will also facilitate the fire extinguishing nozzle 405 to cover and spray the area under the vehicle, thereby ensuring the spatial coordination of the overall operation process.

[0044] A power cut-off device 8 is fixedly connected to the top of the charging pile 6, and a distributed smoke detector 7 is fixedly connected to the inside of the carport body 2. The distributed smoke detector 7 is electrically connected to the charging pile 6 through the power cut-off device 8.

[0045] In the aforementioned components, the distributed smoke detector 7 continuously monitors the smoke status inside the carport body 2. When an abnormal smoke signal is detected, it sends a power-off command to the charging pile 6 through the power cut-off device 8, causing the charging pile 6 to stop supplying power and avoid further danger caused by continuous charging. At the same time, the distributed smoke detector 7 transmits the signal to the relevant electrical components to realize the synchronous linkage between fire identification and power supply control, providing triggering conditions for subsequent fire extinguishing actions.

[0046] A transfer pump 402 is fixedly connected to the back side of the base 1. A connecting pipe 401 is fixedly connected to the inlet end of the transfer pump 402. An installation pipe 407 is fixedly connected to the outlet end of the transfer pump 402. One end of the installation pipe 407 is fixedly connected to the delivery pipe 406.

[0047] In the aforementioned components, after the fire extinguishing is activated, the transfer pump 402 obtains the fire extinguishing medium through the connecting pipe 401 connected to its inlet end, and under the action of pumping, it is transported through the installation pipe 407 connected to its outlet end. The installation pipe 407 and the delivery pipe 406 form a communication structure, so that the fire extinguishing medium can stably enter the delivery pipe 406 inside the moving frame 404, and be continuously supplied to the fire extinguishing nozzle 405 under pressure, thereby ensuring the continuity and reliability of the fire extinguishing spray process.

[0048] An inert gas injector 412 is fixedly connected to the top of the movable frame 404. The inert gas injector 412 is electrically connected to the transfer pump 402. The transfer pump 402 is electrically connected to the drive motor 403. The drive motor 403 is electrically connected to the distributed smoke detector 7.

[0049] In the aforementioned components, the inert gas injector 412 is located at the top of the movable frame 404 and is electrically connected to the transfer pump 402. After the transfer pump 402 is started, it enters the working state synchronously and achieves spray control through electrical linkage. At the same time, the electrical connection between the transfer pump 402 and the drive motor 403 ensures that the movement and spraying actions are coordinated. The drive motor 403 is also controlled by the distributed smoke detector 7, so that the entire automatic fire extinguishing mechanism 4 can achieve orderly linkage operation based on the smoke detection results.

[0050] A filter screen 303 is snapped onto the top of the carport body 2. Transmission pipes 301 are fixedly connected to both sides of the carport body 2. An electric valve 302 is connected to the middle of each of the two transmission pipes 301. Cooling nozzles 304 are fixedly connected to the outer sides of each of the two transmission pipes 301.

[0051] In the aforementioned components, the filter screen 303 at the top of the carport body 2 filters the air inside the carport in a closed state, reducing the diffusion of impurities. The transmission pipes 301 on both sides of the carport body 2 are opened as needed under the control of the electric valve 302, so that the fire extinguishing or cooling medium is transported to the cooling nozzle 304 through the transmission pipe 301. The cooling nozzle 304 sprays the medium to the areas on both sides of the carport body, and provides auxiliary adjustment of the local temperature during the closed fire extinguishing process, in line with the overall fire protection operation requirements.

[0052] Mounting brackets 306 are fixedly connected to both sides of the bottom end of the carport body 2, and a dual-shaft motor 307 is fixedly connected to the inside of the mounting brackets 306.

[0053] In the aforementioned components, the mounting bracket 306 is fixed to both sides of the bottom end of the carport body 2, providing a stable mounting base for the dual-axis motor 307. Under the support of the mounting bracket 306, the dual-axis motor 307 maintains the coaxial state of the output shaft and the winding wheel 308, so that when the dual-axis motor 307 is powered on, it can synchronously drive the two winding wheels 308 to rotate, thereby applying traction force to the connecting rope 309, ensuring that the closing mechanism 3 moves in a coordinated and stable manner during opening or closing.

[0054] The bottom end of the mounting bracket 306 is fixedly connected to a limiting rod 310, the bottom end of the limiting rod 310 passes through the closed blade 305, and one end of the cooling nozzle 304 is placed on the outside of the closed blade 305.

[0055] In the above components, the limiting rod 310 is fixedly connected to the bottom of the mounting frame 306 and passes through the sealing blade 305. It plays a guiding and limiting role during the movement of the sealing blade 305, so that the sealing blade 305 moves up and down along a predetermined path to avoid swaying or jamming. The cooling nozzle 304 is set on the outside of the sealing blade 305. After sealing is completed, it sprays on the outer area, so that the sealing blade 305 can form an isolation structure while taking into account the cooling needs of the outside.

[0056] The drive motor 403 is electrically connected to the dual-shaft motor 307.

[0057] In the aforementioned components, the drive motor 403 and the dual-shaft motor 307 are electrically connected so that they can operate synchronously or in conjunction under the action of control signals. While the automatic fire extinguishing mechanism 4 moves, the closing mechanism 3 is driven to move, so that the fire extinguishing spray and the enclosure closing are coordinated in time and action, thereby forming a continuous mechanical response process when a fire occurs, ensuring the continuity and consistency of the overall fire protection process.

[0058] Working principle: Under normal use, electric vehicles are parked under the carport body 2 and charged through the charging pile 6. The carport body 2 is stably connected to the base 1 at its bottom to form an overall support structure. The sealing mechanism 3 is in the open state. The sealing blades 305 are pulled together on both sides of the carport body 2 under the traction of the adjusting rod 311 and the connecting rope 309, without affecting vehicle entry and exit and daily ventilation. The distributed smoke detector 7 and the heat source sensor 408 continuously monitor the internal environment of the carport body 2.

[0059] When an electric vehicle generates abnormal high temperature or smoke due to battery thermal runaway, electrical faults or other reasons during charging or parking, the distributed smoke detector 7 first detects the smoke signal and cuts off the power supply to the charging pile 6 through the power cut-off device 8, blocking the electrical risk from the source. At the same time, the distributed smoke detector 7 sends a start signal to the drive motor 403 and the transfer pump 402.

[0060] After the drive motor 403 starts, it drives the lead screw 410 connected to its output end to rotate. Since the sliding support 409 and the lead screw 410 are threadedly connected, the sliding support 409 moves linearly along the guide rail 411 on the inner side of the base 1 under the rotation of the lead screw 410. The sliding support 409 maintains stable operation under the limiting action of the guide rail 411, avoiding deviation or shaking. The moving frame 404 connected to the top of the sliding support 409 moves synchronously, so that the delivery pipe 406 and the fire extinguishing nozzle 405 can be adjusted in position along the bottom of the carport body 2, thereby achieving directional coverage of the fire area.

[0061] During the movement of the sliding support 409, the heat source sensor 408 fixed at its top continuously detects the local temperature. When it moves to the area with the highest temperature, the heat source sensor 408 feeds back the position signal to the drive motor 403, so that the sliding support 409 stops at the optimal position, ensuring that the fire extinguishing nozzle 405 is directly facing the core area of ​​the fire source, improving fire extinguishing efficiency and reducing the waste of inert gas.

[0062] At the same time, the transfer pump 402 starts working after receiving the start signal. Its inlet end obtains inert extinguishing medium through the connecting pipe 401 and delivers it to the delivery pipe 406 inside the moving frame 404 through the installation pipe 407 connected to the outlet end. Finally, the fire extinguishing nozzle 405 sprays inert gas in a directional manner towards the fire source area, thereby reducing the oxygen concentration and inhibiting the combustion reaction to achieve rapid fire extinguishing and prevent the spread of open flames.

[0063] Simultaneously with the activation of the automatic fire extinguishing mechanism 4, the dual-axis motor 307 is powered on and operates synchronously. Its two output ends drive the corresponding winding wheels 308 to rotate. During the rotation, the winding wheels 308 wind up the connecting rope 309. The connecting rope 309 pulls the adjusting rod 311 upward, causing the adjusting rod 311 to drive the closing blade 305 to move along the direction of the limiting rod 310. Under the guidance and constraint of the limiting rod 310, the closing blade 305 gradually unfolds downward and closes the openings on both sides of the carport body 2, thereby forming a relatively sealed space structure in a short time, effectively preventing the leakage of inert gas and isolating the outside air from entering, further enhancing the fire extinguishing effect.

[0064] After the closed blades 305 are closed, the filter screen 303 connected to the top of the carport body 2 intercepts residual particulate matter in the internal air, reducing the leakage of smoke and dust. At the same time, the transmission pipes 301 on both sides of the carport body 2 are opened by the electric valve 302 when needed, so that the cooling nozzles 304 spray cooling medium onto the outside of the closed blades 305 to assist in cooling the structure of the carport and the surrounding environment, preventing heat from being conducted outward and causing secondary risks.

[0065] Throughout the process, the drive motor 403, dual-shaft motor 307, transfer pump 402, distributed smoke detector 7, and inert gas injector 412 form a linkage control relationship, enabling automatic fire extinguishing, enclosure and isolation, power cut-off and cooling protection to be completed in a predetermined logical sequence, thereby achieving rapid response, precise fire extinguishing and safety protection in the face of electric vehicle shed fire.
