Description

Technical Field

[0001] This utility model relates to the field of smart fire protection technology, and more specifically, to a smart coverage fire extinguishing device for fires in parking spaces of new energy vehicles. Background Technology

[0002] Currently, with the development of science and technology, new energy vehicles are gaining increasing popularity due to their low cost and low pollution. New energy vehicles include four main types: hybrid electric vehicles (HEVs), battery electric vehicles (BEVs, including solar-powered vehicles), fuel cell electric vehicles (FCEVs), and other new energy vehicles (such as those using supercapacitors, flywheels, and other high-efficiency energy storage devices). The functional component of a new energy vehicle is its power battery. Because the charging and discharging process of the power battery involves frequent chemical reactions, thermal runaway and subsequent fires in new energy vehicle batteries are common occurrences. When a new energy vehicle's power battery experiences thermal runaway and catches fire, it is usually accompanied by a release of high temperatures, which can easily cause the fire to spread rapidly, resulting in significant damage to the surrounding environment and the vehicle itself.

[0003] Statistical data shows that the vast majority of fires caused by thermal runaway of new energy vehicle power batteries occur during the high state of charge (SOC) state of the battery, the end of the charging process, and the subsequent static period. Therefore, developing an intelligent fire suppression system for parking spaces of new energy vehicles has significant application value. Utility Model Content

Detailed Implementation

[0034] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and through embodiments. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0035] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist simultaneously. The term " / and" in this article describes another type of relationship between related objects, indicating that two relationships can exist. For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " in this article generally indicates that the related objects before and after it are in an "or" relationship.

[0036] according to Figures 1-11 As shown, an intelligent fire suppression device for a new energy vehicle parking space includes a fire suppression covering component, a bottom water spray fire suppression component, and a thermal runaway intelligent detection component. Both the fire suppression covering component and the bottom water spray fire suppression component are installed on the parking space 1. The fire suppression covering component is used to cover and extinguish the thermal runaway fire of the new energy vehicle 23, and the bottom water spray fire suppression component is used to spray water to cool and extinguish the thermal runaway power battery on the new energy vehicle 23. The thermal runaway intelligent detection component is installed above the parking space 1 to detect the thermal runaway fire state of the new energy vehicle 23 within the parking space 1.

[0037] The fire extinguishing cover includes a fire extinguishing cover housing and a fire extinguishing cover deployment component. The fire extinguishing cover housing is located at the rear end of the parking space 1, and the fire extinguishing cover deployment component is located on the side of the parking space 1. The fire extinguishing cover deployment component is connected to the fire extinguishing cover housing and is used to unfold the fire extinguishing blanket 3 of the fire extinguishing cover housing to cover and wrap the new energy vehicle 23.

[0038] The fire extinguishing cover includes a fire extinguishing container 2 and a fire blanket 3. The fire extinguishing container 2 is a long rectangular groove, and its length is greater than the width of the parking space 1. The bottom outer side of the fire extinguishing container 2 is fixedly and sealed to the parking space line behind the parking space 1. One end of the fire blanket 3 is fixedly and sealed to the bottom surface of the fire extinguishing container 2. The fire blanket 3 is folded in an S-shape inside the fire extinguishing container 2. Furthermore, a tightening groove 4 is provided on one side wall of the fire extinguishing container 2. The tightening groove 4 is U-shaped, and the two tightening grooves 4 correspond one-to-one with the parking space lines on both sides of the parking space 1. The tightening groove 4 facilitates the unfolding of the fire blanket 3 to cover the new energy vehicle 23, and then tightens the two sides of the fire blanket 3 downwards to improve the sealing of the fire blanket 3 covering the new energy vehicle 23. It should be noted that the length and width of the fire blanket 3 meet the requirement of completely covering the new energy vehicle 23. Alternatively, a charging pre-installed pipe 5 is provided at one end of the fire extinguishing container 2 near the bottom of the tank. The charging pre-installed pipe 5 is used for the wires of the charging plug of the new energy vehicle 23 to pass through. This ensures that if the new energy vehicle 23 experiences thermal runaway during the charging process, the fire blanket 3 can still completely cover the new energy vehicle 23.

[0039] The fire extinguishing cover deployment component includes a fire extinguishing cover deployment arm and a fire extinguishing cover tightening component. The fire extinguishing cover deployment arm is located on the side of the parking space 1, and the fire extinguishing cover tightening component is located on the fire extinguishing cover deployment arm and is connected to the fire extinguishing cover receiving component.

[0040] The fire-extinguishing deployment arm includes a fire-extinguishing deployment transmission component and a fire-extinguishing deployment power component. The fire-extinguishing deployment transmission component is disposed on the side of the parking space 1, and the fire-extinguishing deployment power component is connected to the fire-extinguishing deployment transmission component. The fire-extinguishing deployment transmission component includes a first transmission arm 6 and a second transmission arm 7. The first transmission arm 6 is disposed on the side of the parking space 1, and the second transmission arm 7 is hinged to the first transmission arm 6.

[0041] The first transmission arm 6 is in the shape of a long rectangular groove, and its length is greater than half the length of the parking space 1. The outer side of the groove bottom of the first transmission arm 6 is fixedly and sealed on the parking space line on the side of the parking space 1, and one end of the first transmission arm 6 is connected to one side wall of the fire extinguishing container 2. At the same time, the groove opening at one end of the first transmission arm 6 is connected to the tightening groove 4. Furthermore, the inner sides of the groove openings on both sides of the first transmission arm 6 are provided with first fire-resistant rubber strips. The first fire-resistant rubber strips adhere to the tightened fire extinguishing blanket 3 to increase the lateral sealing of the wrapping.

[0042] The inner wall groove width of the second transmission arm 7 is not less than the outer wall groove width of the first transmission arm 6, and the length of the second transmission arm 7 is not less than the length of the first transmission arm 6. A first rotating shaft 8 is fixedly provided through one end of the groove wall on one side of the second transmission arm 7, and one end of the first rotating shaft 8 rotatably passes through the other end of the groove wall on one side of the first transmission arm 6, so that the second transmission arm 7 can rotate and unfold around the other end of the first transmission arm 6 by rotating the first rotating shaft 8. A second rotating shaft 9 is fixedly provided through one end of the groove wall on the other side of the second transmission arm 7, and one end of the second rotating shaft 9 rotatably passes through the other end of the groove wall on the other side of the first transmission arm 6, so as to improve the stability of the second transmission arm 7 during unfolding and folding on the first transmission arm 6. Furthermore, the length of each end of the first rotating shaft 8 and the second rotating shaft 9 extending into the groove of the first transmission arm 6 is not greater than 5mm, so as to avoid obstructing the fire blanket 3 from being tightened into the grooves of the first transmission arm 6 and the second transmission arm 7. Alternatively, a second fire-resistant rubber strip is provided on the outer side of the bottom of the second transmission arm 7 groove to improve the sealing between the bottom of the second transmission arm 7 groove and the parking space line on the side of the parking space 1 after the second transmission arm 7 is fully extended.

[0043] The fire extinguishing deployment power component includes a worm gear, a first motor 10, a drive shaft, and a worm. The worm gear is fixedly mounted on the other end of the first rotating shaft 8. The first motor 10 is fixedly mounted on the parking space 1 at the angle where the first transmission arm 6 and the fire extinguishing container 2 connect. One end of the drive shaft is connected to the rotating shaft of the first motor 10, and the worm is mounted on the other end of the drive shaft, meshing with the worm gear. When the first motor 10 rotates forward, it can drive the first rotating shaft 8 to rotate via the worm and the worm gear. The first rotating shaft 8 drives the second transmission arm 7 to unfold from the first transmission arm 6 to a horizontal state, so that the outer side of the groove bottom of the second transmission arm 7 is tightly attached to the parking space line on the side of the parking space 1. Furthermore, a gear housing 11 is fitted around the worm gear and the worm. The gear housing 11 is generally rectangular in shape. A gear transmission groove is provided on one side of the gear housing 11. The bottom of the gear housing 11 is fixedly installed on the parking space 1. The gear transmission groove is sleeved on the worm gear and the worm to provide protection. At the same time, the gear transmission groove opening is circumferentially sliding and sealed with the outer side of the groove wall of the second transmission arm 7, which improves the stability of the gear housing 11 against wheel crushing.

[0044] Two sets of fire-extinguishing cover extension arms are provided, and the two sets of fire-extinguishing cover extension arms are symmetrically distributed on the parking lines on both sides of the parking space 1. This further improves the stability of pulling the fire blanket 3 out of the fire extinguishing container 2 and covering the new energy vehicle 23, and makes it easier to tighten the two sides of the fire blanket 3, thereby improving the circumferential sealing of the cover.

[0045] The fire blanket extinguishing tightening component includes a tightening support, a tightening power component, and a tightening rope 12. The tightening support is mounted on the fire blanket extinguishing deployment transmission component and is connected to the other end of the fire blanket 3. The tightening power component is mounted on the tightening support and the tightening rope 12 is mounted on the tightening power component and is located on the top surface of the fire blanket 3.

[0046] The covering and tightening support includes a covering and tightening support tube 13. Both ends of the covering and tightening support tube 13 are correspondingly mounted on the other ends of the second transmission arms 7 of the two sets of covering and fire-extinguishing deployment arms. The side of the covering and tightening support tube 13 is fixedly and sealed to the other side of the fire blanket 3. The covering and tightening support tube 13 is rectangular, with a cross-sectional dimension smaller than the cross-sectional dimension of the fire extinguishing container 2, and a length smaller than the length of the fire extinguishing container 2. This allows the covering and tightening support tube 13 to be driven by the second transmission arm 7 and laterally embedded into the slot of the fire extinguishing container 2. When the second transmission arm 7 unfolds from the first transmission arm 6, it pulls the covering and tightening support tube 13 out of the fire extinguishing container 2. The covering and tightening support tube 13 then pulls the other end of the fire blanket 3 out of the fire extinguishing container 2 and unfolds. As the second transmission arm 7 continues to unfold, the fire blanket 3 completely covers the new energy vehicle 23. The side wall of the covering and tightening support tube 13 is provided with tightening holes, which are connected to the other end of the second transmission arm 7. The two tightening holes correspond one-to-one with the two second transmission arms 7.

[0047] The cover tightening power component includes a second motor and a tightening transmission component. The second motor is fixedly embedded in the axial center of the cover tightening support tube 13, and the tightening transmission component is disposed on the second motor and connected to the tightening rope 12. The second motor is a dual-axis motor. The tightening transmission component includes a transmission rod 14 and a tightening disc 15. The transmission rod 14 is disposed on the second motor, and the tightening disc 15 is fitted onto the transmission rod 14 and connected to the tightening rope 12.

[0048] One end of the transmission rod 14 is horizontally fixed on a rotating shaft of the second motor, and the other end of the transmission rod 14 is horizontally rotatably mounted on one end face of the covering tightening support tube 13. The tightening disc 15 is generally in the shape of a thick-walled cylindrical tube. The tightening disc 15 is axially sliding and circumferentially locked onto the transmission rod 14, and the outer wall of the tightening disc 15 is wound and connected to one end of the tightening rope 12. Furthermore, the slider on the inner wall of the tightening disc 15 cooperates with the sliding groove on the transmission arm. When the tightening disc 15 continuously winds one end of the tightening rope 12, the tightening disc 15 will continuously slide axially on the transmission rod 14, so that the tightening rope 12 is wrapped in a single layer on the tightening disc 15. The other end of the tightening rope 12 passes through the tightening hole and the tightening through hole 16 on the other end of the fire blanket 3, and then extends from the top surface of the fire blanket 3 and connects to the fire extinguishing container 2. Furthermore, the top surface of the fire blanket 3 is provided with anti-slip strips 17. These anti-slip strips 17 are long strips of fabric made of fire-resistant material. Both ends of the anti-slip strips 17 are horizontally fixed to the top surface of the fire blanket 3 along the parking space 1, for the tightening rope 12 to pass through. Alternatively, multiple anti-slip strips 17 are evenly spaced along the extension direction of the tightening rope 12. The anti-slip strips 17 prevent the tightening rope 12 from slipping off the fire blanket 3 when it is tightened, improving the reliability of the lateral tightening of the fire blanket 3 by the tightening rope 12.

[0049] When the fully extended second transmission arm 7 drives the covering and tightening support tube 13 to adhere to the ground in front of the parking space 1, so that the fire blanket 3 completely covers the new energy vehicle 23, the second motor is started to rotate in the forward direction, thereby driving the tightening disc 15 to wind one end of the tightening rope 12 in the forward direction. As the tightening disc 15 continues to wind, the tightening rope 12 presses the side of the fire blanket 3 into the grooves of the first transmission arm 6 and the second transmission arm 7, improving the lateral sealing of the fire blanket 3 for the thermal runaway new energy vehicle 23.

[0050] Two sets of tightening transmission components are provided, and the two sets of tightening transmission components are symmetrically connected to the two rotating shafts of the second motor within the covering tightening support tube 13. Two tightening ropes 12 are provided, and the two tightening ropes 12 are connected one to one of the two sets of tightening transmission components, and the two tightening ropes 12 are symmetrically distributed on both sides of the fire blanket 3 to simultaneously tighten both sides of the fire blanket 3, thereby wrapping both sides of the new energy vehicle 23.

[0051] The bottom water spray fire extinguishing device includes a spray pipe 18, a nozzle 19, a nozzle protection seat 20, and a nozzle protection cover 21. The length of the spray pipe 18 is less than the longitudinal length of the parking space 1. The spray pipe 18 is horizontally arranged longitudinally on the parking space 1. The nozzle 19 is disposed through one end of the spray pipe 18 and is used to spray fire extinguishing agent upwards, thereby spraying it onto the thermally runaway power battery of the new energy vehicle 23 to extinguish and cool it. Furthermore, multiple nozzles 19 are provided, and the multiple nozzles 19 are evenly distributed at one end of the spray pipe 18. The nozzle protection seat 20 is generally in the shape of an elongated triangular block. The right-angle side of the nozzle protection seat 20 is fixedly disposed on one side of the spray pipe 18 to protect the nozzle 19. Two nozzle protection seats 20 are provided, and the two nozzle protection seats 20 are symmetrically distributed on both sides of the spray pipe 18 to prevent the wheels from pressing on the nozzle 19 and damaging it. The bevel of the nozzle protection seat 20 is arc-shaped.

[0052] A protective groove 24 is provided on the top of the other right-angled side of the nozzle protection seat 20, corresponding to the nozzle 19. The protective groove 24 is arc-shaped, and the centers of the two protective grooves 24 at the same axial position on the two nozzle protection seats 20 coincide to improve the circumferential spray angle of the nozzle 19. Alternatively, the two protective grooves 24 at the same position are located on the same spherical surface to improve the efficiency of the nozzle protection cover 21 being pushed out by the extinguishing agent sprayed from the nozzle 19. The sidewall of the nozzle protection cover 21 is arc-shaped, and the nozzle protection cover 21 is fitted into the two protective grooves 24 at the same center. The dustproof groove on the bottom surface of the nozzle protection cover 21 covers the nozzle 19 to prevent dust accumulation and blockage on the nozzle 19. When the nozzle 19 sprays upward, it will push the nozzle protection cover 21 out of the protective groove 24 to avoid affecting the upward spraying and cooling extinguishing of the nozzle 19.

[0053] Alternatively, two sets of bottom water spray fire extinguishing devices are provided, symmetrically distributed laterally along the parking space 1 to increase the lateral spray width. The other end of the spray pipe 18 of each set is connected to one end of the spray relay pipe 22. The other end of the spray relay pipe 22 passes through the fire extinguishing container 2 and is connected to a fire pump. The fire pump pressurizes the extinguishing agent in the fire water tank and inputs it into the spray relay pipe 22 until it is sprayed from the nozzle 19 onto the new energy vehicle 23 for cooling and fire extinguishing. It should be noted that the fire pump and fire water tank are selectively installed in the parking garage where the parking space 1 is located or installed on the ground nearby, depending on the site environment. The fire water tank stores extinguishing agent.

[0054] Alternatively, a proportioning mixer is connected to the spray relay pipe 22, and a fire extinguishing agent concentrate storage tank is connected to the side wall of the proportioning mixer. The other end of the spray relay pipe 22 is connected to the municipal water supply network. This allows the fire pump to draw water from the municipal water supply network via the spray relay pipe 22, pressurize it, and then mix it thoroughly with the fire extinguishing agent concentrate in the fire extinguishing agent concentrate storage tank through the proportioning mixer before delivering it to the nozzle 19 to spray and extinguish the fire on the new energy vehicle 23. It should be noted that the fire extinguishing agent concentrate and the tap water mix to form the fire extinguishing agent.

[0055] The thermal runaway intelligent detection device includes a thermal runaway detector and a 5G smart fire protection cloud platform. The thermal runaway detector is installed above the parking space 1, and the 5G smart fire protection cloud platform is located in a remote data center. The thermal runaway detector includes a smoke and temperature integrated detector, an image fire detector, and an infrared detector. The smoke and temperature integrated detector, the image fire detector, and the infrared detector are all installed above the parking space 1 and are used to link with the covering fire extinguishing device and the bottom water spray fire extinguishing device to activate the fire linkage system. The smoke and temperature integrated detector is installed on the ceiling above the parking space 1 to detect fires in the new energy vehicle 23 in the parking space 1.

[0056] Furthermore, the smoke and temperature integrated detector is a wireless smoke and temperature integrated detector. The smoke and temperature integrated detector is equipped with a signal transmitter, which enables the smoke and temperature integrated detector to transmit IoT signals with telecommunications operators, and to wirelessly transmit detected smoke and temperature abnormality signals to the fire control room of the user unit in a timely manner, as well as to the 5G smart fire protection cloud platform over long distances.

[0057] It should be noted that the adoption of wireless network-connected smoke and temperature integrated detectors will significantly improve the efficiency and intelligence of fire protection construction. These detectors have built-in batteries, require no wiring, and are simple and quick to install, significantly shortening the construction cycle. They also feature low power consumption, real-time device status monitoring, and alarms for tampering, low battery, fault, and over-temperature conditions.

[0058] The image fire detector is installed on the ceiling above the parking space 1 to monitor the new energy vehicle 23 in the parking space 1 for fire and video surveillance, reducing the blind spot of the image fire detector and improving its detection timeliness and accuracy. The infrared detector is installed on the ceiling above the parking space 1 to detect abnormal temperatures in the new energy vehicle 23 in the parking space 1.

[0059] Alternatively, a temperature detector is installed on the wall of the fire extinguishing container 2 facing the parking space 1. When the fire blanket 3 completely covers and wraps around the new energy vehicle 23, the temperature detector can detect the temperature inside the fire blanket in real time, and the temperature detector transmits the real-time temperature to the APP on the manager's mobile phone via wireless network.

[0060] The 5G smart fire protection cloud platform continuously collects parameters from social units, management personnel, equipment quantity, smoke and temperature integrated detectors, image fire detectors, and infrared detectors 24 / 7. This data is then uploaded to the monitoring center's server via 5G wireless communication, where the city's smart safety cloud platform system performs real-time online monitoring, statistical analysis, and other functions. Users can monitor the safety status parameters of on-site equipment in real time via mobile app and PC client, achieving transparent monitoring and management of safety equipment and allowing them to control the health status and energy efficiency of safety equipment anytime, anywhere.

[0061] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
