Description
Technical Field
[0001] This utility model relates to the field of fire protection facilities technology, and in particular to a fire protection device and system for parking spaces of new energy vehicles. Background Technology
[0002] With the transformation of the energy structure and the increasing awareness of environmental protection, new energy vehicles have gradually become a hot topic in the automotive industry. New energy vehicles, especially electric vehicles, are widely used in urban transportation and personal travel due to their clean energy and low emissions. However, safety issues during the charging process of electric vehicles, especially fires caused by battery thermal runaway, have become a focus of industry attention.
[0003] Currently, electric vehicles primarily use lithium-ion batteries as their power source. Lithium-ion batteries are widely used in the new energy vehicle sector due to their high energy density, long cycle life, and low self-discharge rate. However, under extreme conditions such as overcharging and short circuits, batteries are prone to thermal runaway, leading to fires or even explosions. Existing charging stations and parking spaces are typically equipped with portable fire extinguishers or fire hydrants, but these firefighting facilities suffer from low extinguishing efficiency and difficulty in achieving point-to-point fire suppression. Furthermore, conventional firefighting systems often employ a top-down spraying method, where the spray medium is easily consumed by smoke and fire plumes, making it difficult to effectively suppress the fire source and resulting in low extinguishing efficiency. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model embodiment is to provide a fire-fighting device for parking spaces of new energy vehicles.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A fire-fighting device for a new energy vehicle parking space includes: a fixed frame, a support frame, and a fire extinguishing cover; the fixed frame includes a fixing part and an installation part, the fixing part is fixed to the ground of the parking space, and the side of the installation part is provided with a protruding ridge; the support frame includes a support part and a load-bearing part, the load-bearing part is pressed against the top surface of the installation part, and the side of the support part is provided with a groove, the groove being inserted into the protruding ridge of the installation part; the fire extinguishing cover is installed on the load-bearing part, and the fire extinguishing cover is provided with a detector, a water mist nozzle, and a water-based nozzle, the detector and the water mist nozzle are arranged on the top surface of the fire extinguishing cover, and the water-based nozzle is arranged at the edge of the top surface of the fire extinguishing cover and at a predetermined angle to the horizontal plane.
[0007] This utility model embodiment also provides a fire protection system for a new energy vehicle parking space, including a fire protection module and the fire protection device for the new energy vehicle parking space as described above. The fire protection module includes a PLC control unit, a water-based fire extinguishing agent storage tank, a booster pump, a water-based interface, a water mist interface, a communication interface, and a pressure gauge. The PLC control unit is electrically connected to the detector and the booster pump. The water-based fire extinguishing agent storage tank is connected to the water-based nozzle through the water-based interface and pipeline. The water mist interface is connected to the water mist nozzle through pipeline.
[0008] One or more technical solutions provided in the embodiments of this utility model have at least the following technical effects or advantages:
[0009] 1. When the detector detects a fire, the fire suppression system will activate immediately. Water mist nozzles spray water mist to rapidly reduce the temperature of the fire, while water-based nozzles spray water-based extinguishing agents to effectively suppress and extinguish the fire source, cutting off the combustion chain. The combination of water mist nozzles and water-based nozzles achieves a dual fire suppression effect. Furthermore, because the spray direction is from bottom to top, compared to the traditional top-down spraying method, it can effectively suppress the fire source and improve fire suppression efficiency. This fire-fighting device solves the safety hazards in the charging process of existing new energy vehicles, effectively suppresses the spread of fire, reduces losses caused by fire, and improves charging safety.
[0010] 2. The fixing part is used to securely install the device on the ground of the parking space, while the mounting part is used to connect with the support frame. The mounting part has protruding ribs on its side, and the support part has grooves that match the protruding ribs of the fixing frame. The cooperation of the protruding ribs and grooves allows the support frame to be easily installed on the fixing frame. Compared to underground installation, this fire-fighting device allows the fire extinguisher and support frame to be pulled out together in case of a malfunction, facilitating later disassembly and maintenance.
[0011] 3. Water-based nozzles are positioned at the edge of the top surface of the fire extinguishing hood, at a predetermined angle to the horizontal plane. Combined with water mist nozzles, this ensures effective coverage of a larger area. The nozzle arrangement allows for a smaller overall profile of the fire extinguishing hood while maintaining a sufficient fire suppression area.
[0012] Additional advantages of this invention will be set forth in the description which follows, and in part will be obvious from the description or may be learned by practice of the invention. Attached Figure Description

[0026] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0027] like Figure 1 The diagram shows a new energy vehicle parked in parking space 1. Battery 2 is located in the middle, with the front-wheel drive assembly of the vehicle on the front side (lower side of the diagram) and the rear-wheel drive motor on the rear side. Figure 2 As shown, the arrangement of the fire-fighting device in parking space 1 is given. Of course, it is understandable that the fire-fighting device can be applied to parking space 1 for ordinary vehicles.
[0028] like Figure 3 , Figure 4 As shown, the fire-fighting device for new energy vehicle parking spaces includes a fixed frame 6, a support frame 5, and a fire extinguishing cover 3; Figure 8 As shown, the fixing frame 6 includes a fixing part 61 and an mounting part 62. The fixing part 61 is fixed to the ground of the parking space 1, and the mounting part 62 has a protruding ridge on its side. The support frame 5 includes a support part 52 and a bearing part 51. The bearing part 51 is pressed against the top surface of the mounting part 62, and the support part 52 has a groove on its side, which is inserted into the protruding ridge of the mounting part 62. The fire extinguishing cover 3 is mounted on the bearing part 51. The fire extinguishing cover 3 is equipped with detectors (temperature sensor 35 and smoke sensor 37, etc.), water mist nozzles 34, and water-based nozzles 33. The detectors and water mist nozzles 34 are arranged on the top surface of the fire extinguishing cover 3. The detectors are located in the middle, and the water mist nozzles 34 are fan-shaped high-pressure nozzles, evenly distributed throughout the entire area of the fire extinguishing cover 3. The water-based nozzles 33 are arranged at the edge of the top surface of the fire extinguishing cover 3 and at a predetermined angle to the horizontal plane. The fire extinguishing cover 3 is mounted on the bearing part 51 of the support frame 5 and is mainly used to install key components such as detectors and nozzles. In addition to pipelines, detectors are used to monitor fires.
[0029] During operation, the fire suppression system activates immediately when the detector detects a fire (e.g., excessively high temperature or smoke). Water mist nozzles 34 spray water mist to rapidly reduce the temperature of the fire, while water-based nozzles 33 spray water-based extinguishing agent to effectively suppress and extinguish the fire source, cutting off the combustion chain. The combination of water mist nozzles 34 and water-based nozzles 33 achieves a dual fire suppression effect. Furthermore, because the spray direction is from bottom to top, compared to traditional top-down spraying methods, it effectively suppresses the fire source and improves fire suppression efficiency. This fire-fighting device addresses the safety hazards during the charging process of existing new energy vehicles, effectively suppressing the spread of fire, reducing losses caused by fire, and improving charging safety.
[0030] The fixing part 61 is used to securely install the device on the ground of the parking space 1, and the mounting part 62 is used to connect with the support frame 5. The mounting part 62 has protruding ribs on its side, and the support part 52 has grooves that match the protruding ribs of the fixing frame 6. Through the cooperation of the protruding ribs and grooves, the support frame 5 can be easily installed on the fixing frame 6. Compared to underground installation, this fire-fighting device allows the fire extinguisher 3 and the support frame 5 to be pulled out together when the fire extinguisher 3 malfunctions, facilitating subsequent disassembly and maintenance.
[0031] Water-based nozzles 33 are positioned at the edge of the top surface of the fire extinguishing hood 3 at a predetermined angle to the horizontal plane. Their coordination with water mist nozzles 34 ensures effective coverage of a larger area (e.g., Figure 5 (As shown), this effectively prevents the fire from spreading. This nozzle arrangement ensures a sufficient fire suppression area while reducing the overall profile of the fire extinguishing hood 3.
[0032] like Figure 8 As shown, the fixing part 61 of the fixing bracket 6 is a horizontal plate, ensuring that it can be stably fixed to the ground. The mounting part 62 is a vertical plate. The fixing part 61 and the mounting part 62 form an L-shaped structure. Two fixing brackets 6 are symmetrically installed in each parking space 1, and an installation space is formed between the mounting parts 62 of the two fixing brackets 6. The L-shaped structure not only increases the stability of the device, but also provides a clear installation guide, making subsequent installation and maintenance more convenient.
[0033] like Figure 9 As shown, the fixing part 61 of the fixing frame 6 has bolt holes, and the fixing part 61 is fixed to the ground of the parking space 1 by expansion bolts. The expansion bolts have strong fixing ability and can provide a stable fixing effect on hard surfaces such as concrete.
[0034] like Figure 8 , Figure 10As shown, the support frame 5 has a horizontal plate 51 for supporting the fire extinguishing cover 3, providing a stable mounting surface. The support frame 51 has clearance grooves on both sides and in the middle. The support part 52 is a vertical plate. One support part 51 and two support parts 52 form a π-shaped structure. The support part 52 is installed in the mounting space formed by the fixed frame 6, which not only ensures the stability of the support frame 5, but also makes the installation process of the entire device simpler and ensures that each component can be stably positioned between the fixed frames 6.
[0035] like Figure 8 As shown, the cross-section of the protruding ridge is triangular, and the groove is a triangular structure that matches the protruding ridge. This design provides excellent shear resistance and a more stable insertion effect. The sliding insertion design not only improves the installation efficiency of the device but also allows for quick disassembly and maintenance when needed, enhancing the ease of use of the device.
[0036] like Figure 3 As shown, the fire extinguishing cover 3 includes a main cover 31 and side covers 32, with the side covers 32 symmetrically arranged on both sides of the main cover 31, as shown below. Figure 6 As shown, the main cover 31 has a trapezoidal cross-section, as... Figure 7 As shown, the side cover 32 has an arched cross-section.
[0037] The main enclosure 31 is located in the central part of the fire extinguishing enclosure 3 and adopts a trapezoidal cross-section design. The trapezoidal structure provides better mechanical properties and can effectively support the weight and pressure above the fire extinguishing enclosure 3. The side enclosures 32 are symmetrically arranged on both sides of the main enclosure 31 and adopt an arched cross-section structure. In the event of a fire, they can effectively cover a larger fire extinguishing area.
[0038] The main cover 31 is made of metal, while the side covers 32 are made of plastic. The main cover 31 is made of metal, preferably a fire-resistant and high-strength metal such as stainless steel or aluminum alloy. Metal materials maintain their shape and strength in high-temperature fire environments, preventing deformation or collapse due to heat and ensuring the stable operation of the fire extinguishing system. The side covers 32 are made of plastic, preferably high-temperature resistant and corrosion-resistant engineering plastics such as polycarbonate (PC) or glass fiber reinforced plastic. This material is lightweight and easy to process, reducing the overall weight of the fire extinguishing cover 3 and simplifying installation and maintenance. The use of different materials for the main cover 31 and side covers 32 aims to balance the overall strength and weight of the device. The metal main cover 31 ensures the stability and durability of the device during a fire, while the plastic side covers 32 reduce the overall weight, making the device easier to install and maintain.
[0039] The detector includes a temperature sensor 35 and a smoke sensor 37, which are mounted on the central axis at the top of the main cover 31. The temperature sensor 35 monitors temperature changes in the parking space 1 area in real time. When an abnormal temperature rise is detected, reaching a set fire alarm threshold, the temperature sensor 35 immediately sends a signal to the PLC, triggering the fire extinguishing device. The smoke sensor 37 detects smoke signals that may be generated in the early stages of a fire. When the smoke concentration exceeds a set threshold, the smoke sensor 37 triggers the alarm system and initiates the fire extinguishing process. Additionally, a color recognition sensor 38 can be added to the fire extinguishing cover 3 to improve monitoring accuracy and facilitate timely fire detection.
[0040] The fire protection system also includes an alarm 36, such as a sound and information remote alarm 36, which is installed on the central axis of the top of the main enclosure 31 and located between the temperature sensor 35 and the smoke sensor 37. The alarm 36 uses a high-decibel sound as the alarm signal to ensure that it can be detected quickly in various environments, thus ensuring the efficiency and reliability of the alarm system.
[0041] Based on the aforementioned fire-fighting devices, this embodiment also provides a fire-fighting system for new energy vehicle parking spaces, including a fire-fighting module 4 and fire-fighting devices. For example... Figure 11 As shown, the fire protection module 4 includes a PLC control unit 41, a water-based fire extinguishing agent storage tank 42, a booster pump 43, a water-based interface 44, a water mist interface 45, a communication interface 46, and a pressure gauge 47. The PLC control unit 41 is electrically connected to the detector, the booster pump 43, etc. The water-based fire extinguishing agent storage tank 42 is connected to the water-based nozzle 33 through the water-based interface 44 and the pipeline. The water mist interface 45 is connected to the water mist nozzle 34 through the pipeline.
[0042] The PLC control unit 41 is the core control module of the entire fire protection system. It receives signals from the temperature sensor 35 and the smoke sensor 37, and controls the start-up of the booster pump 43, the spraying of the extinguishing agent, and the triggering of the alarm 36 according to preset program logic. The water-based extinguishing agent storage tank 42 stores water-based extinguishing agent. When a fire occurs, under the command of the PLC control unit 41, the tank delivers the extinguishing agent to the water-based nozzles 33 through the water-based interface 44 for fire extinguishing. The booster pump 43 pressurizes the water-based extinguishing agent in the tank to ensure that the extinguishing agent can be effectively sprayed to the fire source area through the nozzles. The water-based interface 44 delivers the high-efficiency extinguishing agent, while the water mist interface 45 provides water. The communication interface 46 connects the PLC control unit 41 to various sensors. The pressure gauge 47 monitors the pressure changes during the delivery of the water-based extinguishing agent and water in real time to ensure the system operates under optimal conditions.
[0043] This fire protection system integrates components such as a PLC control unit 41, a booster pump 43, and a water-based extinguishing agent storage tank 42 to form an intelligent and efficient fire extinguishing system. The system can respond rapidly in the event of a fire, automatically execute fire extinguishing operations, ensure timely and effective fire control, and reduce casualties and property damage.
[0044] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
