Description

Technical Field

[0001] The present invention relates to the technical field of garage safety devices, and in particular to a new energy parking space fire arrester device and a control method thereof. Background Art

[0002] As the world's attention to environmental protection and sustainable development continues to increase, the number of new energy electric vehicles in the market has shown explosive growth due to their advantages such as energy saving and environmental protection. The widespread use of new energy electric vehicles has greatly changed people's travel methods, reduced dependence on traditional fuel, and effectively reduced carbon emissions. However, while new energy electric vehicles bring convenience, they are also accompanied by a series of safety hazards, especially during the charging process, where fire accidents occur frequently, posing a serious threat to people's lives and property.

[0003] The main power source of new energy electric vehicles is lithium batteries. Lithium batteries have the advantages of high energy density and long cycle life, but they also have the problem of poor thermal stability. During the charging process, complex electrochemical reactions will occur inside the battery. If the battery is aging or has poor heat dissipation, it may cause thermal runaway of the battery and cause a fire. Moreover, lithium battery fires develop rapidly and fiercely. The high temperature and toxic smoke generated will cause serious damage to the surrounding environment in a short period of time. Therefore, in order to effectively control fires that occur in new energy electric vehicles in parking spaces, people have set up fire-blocking and fire-extinguishing measures in parking spaces.

[0004] Defects of existing technology:

[0005] 1. There may be some infrastructure above the existing electric vehicle parking spaces, and some fire-blocking and fire-extinguishing facilities may be inconvenient to install;

[0006] 2. In actual parking scenarios, there is still the problem of irregular parking, which cannot be solved by regulating driver behavior or through low-cost methods. In many cases, electric vehicles are parked haphazardly and are not precisely positioned according to parking space lines. Their rearview mirrors or other protruding parts often exceed the boundaries of the parking space. Some existing fire prevention measures, such as fire curtains, will automatically fall once a fire is detected to prevent the spread of fire. However, due to the protruding parts of these irregularly parked electric vehicles, the fire curtains are easily stuck during the falling process, resulting in their inability to fall completely and form an effective fire barrier. The fire has a channel to spread, further exacerbating the fire hazard.

[0007] In view of this, in order to build a solid safety line for new energy electric vehicle parking spaces, it is urgent to develop targeted fire-blocking and fire-extinguishing devices. Only in this way can we respond accurately and quickly to the fire at the first time it occurs, protecting people's lives and property safety. Summary of the Invention

[0008] The present invention provides a new energy parking space fire arresting device and a control method thereof, which can effectively solve the above problems.

[0009] The present invention is achieved in that:

[0010] A new energy parking space fire-blocking device, comprising:

[0011] Main controller;

[0012] Hanging frame, installed above the parking space;

[0013] A fire identification component is used to identify whether a fire has occurred in a parking space;

[0014] a fire-blocking assembly comprising a fire curtain detachably connected to the lower end surface of the hanging frame, the fire curtain being made of a flexible fire-blocking material, the fire curtain being provided with a row of a plurality of transverse counterweights at the lower edges of the two wide sides along the width direction of the parking space, and a plurality of longitudinal counterweights at the lower edges of the two long sides along the length direction of the parking space, the front and rear adjacent longitudinal counterweights being connected in a limited sliding manner, and when one of the longitudinal counterweights is blocked and stopped during its falling process, the adjacent longitudinal counterweight at one end thereof is subjected to a limited sliding manner with the longitudinal counterweight, and an impact force is generated toward the outside of the parking space on the blocked and stopped longitudinal counterweight;

[0015] A release component is controlled by the main controller and is arranged on the hanging frame, and is used to release the fire curtain to descend.

[0016] As a further improvement, the longitudinal counterweight block has a main body in the form of a triangular prism, and a cross-sectional profile of an isosceles right triangle, wherein the hypotenuse of the isosceles right triangle in the triangular prism faces the inside of the parking space;

[0017] The longitudinal counterweight block is provided with a slot at one end and a circular connecting post at the other end. The slot is composed of a long strip portion and a circular portion. The connecting post is inserted into the slot from the circular portion and moves into the long strip portion for sliding engagement.

[0018] The axis of the length direction of the long strip portion forms an angle α with the hypotenuse of the isosceles right triangle, where 0°<α≤40°. The upper end surface of the longitudinal counterweight block is provided with a first mounting groove for connecting with the fire curtain. The two ends of the long strip portion are two semicircles with equal radius, and the center of the semicircle close to the top is located in the same vertical plane as the center line of the first mounting groove and the center of mass of the longitudinal counterweight block.

[0019] As a further improvement, the transverse counterweight block consists of a semi-cylindrical portion and a rectangular portion. The lower end faces of the semi-cylindrical portion and the rectangular portion are both inclined surfaces and are smoothly connected. The inclined surfaces face the inside of the parking space. The upper end face of the transverse counterweight block is provided with a second mounting groove for connecting with the fire curtain.

[0020] As a further improvement, the release assembly includes several electromagnetic pins provided on the hanging frame for releasing the first steel wire rope connected to the bottom of the fire curtain, and the upper end surface of the hanging frame is provided with fixed pulleys on both sides of each electromagnetic pin.

[0021] As a further improvement, the fire curtain is made of flame-retardant and fire-resistant basalt fiber fire curtain cloth and is folded and stored above the parking space. Several lower slits are provided around the lower edge of the fire curtain, and a horizontal counterweight block or a longitudinal counterweight block is provided between two adjacent lower slits. The horizontal counterweight block and the longitudinal counterweight block are both made of aluminum alloy.

[0022] As a further improvement, it further includes at least four water spray nozzles, which are arranged on the hanging frame and connected to the solenoid valve through pipes.

[0023] As a further improvement, it further includes at least one electrically-controlled triggered fire extinguishing bomb, which is suspended on the hanging frame.

[0024] As a further improvement, the fire identification component adopts a camera smoke and flame identification device, and also includes an on-site emergency switch for on-site personnel to manually press the emergency switch when a fire is discovered to send a fire alarm signal to the main controller.

[0025] As a further improvement, the lower end surface of the hanging frame is provided with a circle of hanging rings, the top of the fire curtain is provided with a curtain head, the curtain head is provided with a number of upper slits, the hanging rings correspond to the upper slits one by one and are provided with a second steel wire rope passing through them in sequence to connect them, wherein the second steel wire rope is connected head to tail, the length of the head and tail of the second steel wire is 10-30 cm, and the connection is located on the outside of the fire curtain.

[0026] As a further improvement, a control method for a new energy parking space fire arrester device includes the following steps:

[0027] S1. The fire identification component identifies a vehicle fire and sends a fire signal to the main controller;

[0028] S2. The main controller controls the release assembly to release the fire curtain and simultaneously controls the solenoid valve to open;

[0029] S3. After a delay of 2-5 minutes, the main controller controls the electronically controlled trigger fire extinguishing bomb to start.

[0030] The beneficial effects of the present invention are:

[0031] 1. The fire identification component identifies a fire in a parking space and triggers the fire curtain to descend. The fire curtain is equipped with horizontal counterweights across the width of the parking space and longitudinal counterweights along its length. The adjacent longitudinal counterweights are connected in a limited sliding manner. When one longitudinal counterweight is blocked, the adjacent counterweight generates an outward impact force. Because the fire curtain is made of a flexible material, the blocked longitudinal counterweight can be moved outward, pulling the fire curtain downward to continue descending. This solves the problem of the fire curtain being easily blocked by the vehicle's rearview mirror due to non-standard parking positions.

[0032] 2. The special shape of the longitudinal counterweight works together with the connection structure to improve the performance of the fire curtain. Its main body is a triangular prism with an isosceles right triangle cross section. The hypotenuse faces the inside of the parking space and forms a 45° angle with the horizontal plane. One end is provided with a slot consisting of a long strip and a circular part. The circular connecting column at the other end is inserted into the slot from the circular part and slides inside the long strip. When the fire curtain falls and encounters an electric vehicle rearview mirror or the edge of the roof, if the hypotenuse contacts the obstacle first, the hypotenuse can decompose the resistance of the obstacle into horizontal and vertical components. The horizontal component pushes the obstructed longitudinal counterweight to move to the outside of the parking space. Usually, the upper end surface of the vehicle's rearview mirror is designed to be inclined outward or horizontal. When encountering a rearview mirror with an outward tilt of the upper end surface, the longitudinal counterweight block with a beveled surface can make the fire curtain fall better; if the edge of the bottom of the longitudinal counterweight block contacts the obstacle first, the longitudinal counterweight block will tilt toward the inside of the parking space. Even if the beveled surface of the longitudinal counterweight block is tilted to a horizontal state first, the long strip of the slot always has an angle with the horizontal plane, and the longitudinal counterweight block at the adjacent end slides with it in a limited manner, and generates an impact force toward the outside of the parking space for the blocked and stagnant longitudinal counterweight block; at the same time, the unique connection structure ensures that the counterweight blocks can slide relative to each other without easily detaching. During the long-term use of the fire curtain, even if it is affected by external forces such as vibration and swing, the connection will not fail.

[0033] 3. The release assembly consists of an electromagnetic latch and a fixed pulley. The electromagnetic latch is controlled by the main controller. After receiving the signal, it releases the first steel wire rope connected to the fire curtain to lower the fire curtain. The fixed pulley also facilitates the reset of the fire curtain by pulling up the rope, which is easy to operate.

[0034] 4. Sprinkler assistance: The hanging frame is equipped with at least four sprinkler heads, which are connected to the solenoid valve through pipes and supplied with water from the fire water supply system. Under the control of the main controller, water is sprayed into the inside of the parking space to assist in cooling, suppress the fire, and enhance the fire extinguishing effect;

[0035] Electronically-controlled fire extinguishing bombs assist: In a relatively enclosed space, dry powder fire extinguishing agent quickly forms a high-concentration environment to suppress combustion; compared with carbon dioxide fire extinguishing bombs, the volume of expanding gas during operation is small, and it is not easy to burst the fire curtain or cause the fire curtain to bounce up.

[0058] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0059] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0060] Reference Figures 1 to 9 As shown, a new energy parking space fire-blocking device includes:

[0061] The hanging frame 2 is used to hang the fire-blocking assembly 4, which can be connected to the ceiling above the parking space or the steel structure above the parking space through metal connectors; the middle part of the hanging frame 2 is hollowed out to be used for avoidance lights or other infrastructure such as pipes;

[0062] The fire identification component 3 is used to identify whether a fire has occurred in the parking space; preferably, the fire identification component 3 adopts a camera smoke and flame recognition device, which includes a camera for collecting images and a recognition module including smoke and flame recognition technology. The fire identification component 3 also includes an on-site emergency switch for on-site personnel to manually press the emergency switch when a fire is discovered, thereby sending a fire alarm signal to the main controller 1;

[0063] The fire-blocking assembly 4 includes a fire curtain 41 detachably connected to the lower end face of the hanging frame 2. The fire curtain 41 is made of flexible fireproof material. A row of 20-25 transverse counterweights 43 with a length of 10-15 cm are provided at the lower edge of the two wide sides along the width direction of the parking space. The transverse counterweights 43 can be arranged into an arc shape protruding to the outside of the parking space, which can better match the outline of the front or rear of the car, increase the maximum size of the bottom of the fire curtain 41 along the length direction of the parking space, and avoid the fire curtain 41 from being unable to be fully lowered when the vehicle is parked slightly forward or backward. The fire curtain 41 is placed along the The lower edges of the two long sides of the parking space are provided with 20-25 longitudinal counterweights 42 with a length of 10-15 cm, which are connected to each other in a front-to-rear limited sliding manner. The number and length of the counterweights are selected and set according to the actual size of the parking space. When a longitudinal counterweight 42 is blocked or stopped during its descent, the preceding longitudinal counterweight 42 slides with it in a limited manner, and generates an impact force toward the outside of the parking space on the blocked longitudinal counterweight 42, causing the blocked longitudinal counterweight 42 to move toward the outside of the parking space and pull the fire curtain 41 outward to deform, allowing the fire curtain 41 to continue to fall.

[0064] It should be noted that the length setting of the counterweight block. If the counterweight block is set too long, the force pulling the single counterweight block to move will be large and the amount of local displacement will be limited. If the length is set too short, it will easily lead to an increase in the number of counterweight blocks and the mass of the single unit will be too small, resulting in poor effect.

[0065] The release component 5 is provided on the hanging frame 2 and is used to release the fire curtain 41 to descend. When the main controller 1 receives a fire signal, it sends an activation signal to the release component 5 to descend the fire curtain 41.

[0066] The main controller 1 has a communication module, which can communicate with the fire identification component 3 in a wired / wireless manner. The main controller 1 has a programmable function and is connected to the parking lot fire control platform.

[0067] The main body of the longitudinal counterweight block 42 is a triangular prism, and the cross-sectional profile is an isosceles right triangle. The surface of the hypotenuse of the isosceles right triangle in the triangular prism (i.e., the hypotenuse surface) faces the inside of the parking space; a slot 421 is provided at one end of the longitudinal counterweight block 42, and a circular connecting column 422 is provided at the other end. The slot 421 is composed of a long strip portion 4212 and a circular portion 4211. The connecting column 422 is inserted into the slot 421 from the circular portion 4211 and moved to the long strip portion 4212 for sliding engagement. The connecting column 422 cannot be directly removed from the long strip portion 4212 and can only be slid on the long strip portion 4212; the longitudinal axis of the long strip portion 4212 forms an angle α with the hypotenuse of the isosceles right triangle, where 0°<α≤40°, and the longitudinal The upper end surface of the counterweight 42 is provided with a first mounting groove 423 for connecting with the fire curtain 41. The edge of the fire curtain 41 is inserted into the first mounting groove 423 and fixed by bolts inserted horizontally. The two ends of the long strip 4212 are two semicircles with equal radius, wherein the center of the semicircle near the top and the center line of the first mounting groove 423 and the center of mass of the longitudinal counterweight 42 are located in the same vertical plane, so that when the longitudinal counterweight 42 is hung, the hypotenuse forms a 45° angle with the horizontal plane. The length of the right angle side of the isosceles right triangle is 8-12 cm. Because there is still a gap between the rearview mirror and the side of the vehicle, if the length of the right angle side of the isosceles right triangle is too small, the longitudinal counterweight 42 is easy to get stuck in it, and too long a length will cause waste of material.

[0068] It should be noted that the longitudinal counterweight 42 is provided with a connecting column 422 at one end pointing to the direction of the vehicle entering the parking space. Because the charging port of an electric vehicle is usually located at the rear of the vehicle and the charging pile is located opposite the entrance of the parking space, the vehicle needs to reverse into the garage for charging. At this time, the vehicle's rearview mirror is closer to the end of the entry direction. When the fire curtain 41 is lowered, if the longitudinal counterweight 42 is stuck above the rearview mirror, the number of the blocked longitudinal counterweight 42 on the side close to the connecting column 422 is larger, which can generate a greater impact force toward the outside of the parking space on the blocked longitudinal counterweight 42.

[0069] The lateral counterweight block 43 is composed of a semi-cylindrical portion 431 and a rectangular portion 432. The lower end surfaces of the semi-cylindrical portion 431 and the rectangular portion 432 are both inclined surfaces and are smoothly connected. The inclined surfaces face the inside of the parking space. The upper end surface of the lateral counterweight block 43 is provided with a second mounting groove 433 for connecting with the fire curtain 41. The edge of the fire curtain 41 is inserted into the second mounting groove 433 and fixed by bolts inserted horizontally. If the front or rear part of the vehicle exceeds the range of the fire curtain 41, the inclined surface of the lateral counterweight block 43 contacts the vehicle body when the fire curtain 41 descends, which can make the lateral counterweight block 43 slide toward the outside of the parking space, so that it can fall normally, and usually the upper surface of the front and rear parts of the vehicle has a certain curvature.

[0070] The release assembly 5 includes eight electromagnetic latches 51 arranged on the upper end surface of the hanging frame 2. The electromagnetic latches 51 are connected to the main controller 1 and controlled by it. The number of electromagnetic latches 51 can be increased or decreased as needed to better stably suspend the fire curtain 41. The electromagnetic latch 51 is used to release the first steel wire rope 44 connected to the bottom of the fire curtain 41. The upper end surface of the hanging frame 2 is provided with fixed pulleys 52 on both sides of each electromagnetic latch 51. One end of the first steel wire rope 44 is provided with a ring connected to the electromagnetic latch 51. The movable pin of the electromagnetic latch 51 passes through the ring to fix it. When the electromagnetic latch 51 receives the release signal, the movable pin contracts and releases the ring. The other end of the first steel wire rope 44 is connected to the fire curtain 41 near the lower edge. When it is necessary to test whether the device can be activated and used normally, the fire curtain 41 needs to be pulled up again after being released and lowered. The rope can be connected to the first steel wire rope 44 by passing it around the fixed pulley 52 to pull it up, making the resetting of the fire curtain 41 more convenient.

[0071] The fire curtain 41 is made of flame-retardant and fire-resistant basalt fiber fireproof cloth and is folded and stored above the parking space. The basalt fiber itself has a high melting point, generally around 1450℃-1500℃, and is not easy to melt and deform. It also has good flexibility, which facilitates better sliding between the longitudinal counterweights 42. It is not only easy to cut and process, but also has a lower slit 411 with an equal distance from the length of the counterweight around the lower edge of the fire curtain 41. A horizontal counterweight 43 or a longitudinal counterweight 42 is provided between two adjacent lower slits 411. The horizontal counterweight 43 and the longitudinal counterweight 42 are both made of aluminum alloy, which is easy to deform in the air. It reacts with oxygen to form a dense aluminum oxide film on the surface. This oxide film can prevent the internal aluminum alloy from being further oxidized, giving it a natural rust-proof ability, maintaining stable performance under different environmental conditions, and extending the service life of the counterweight. In addition, this oxide film of the aluminum alloy is stable in nature and has a high hardness, which can prevent direct contact and interaction between aluminum alloy atoms. Even if the two counterweights are in close contact for a long time, due to the existence of the oxide film, they will not stick together or rust and bite each other, ensuring that the longitudinal counterweights 42 can slide in a limited position and will not fail due to adhesion caused by long-term placement.

[0072] Four water sprinklers 7 are also provided on the hanging frame 2, and multiple water sprinklers 7 are connected to a solenoid valve 8 through pipes to control the on and off of water. The solenoid valve 8 is controlled by the main controller 1, and the water sprinklers 7 spray water toward the inside of the parking space. The water sprinklers 7 are supplied with water by the fire water supply system.

[0073] The electric-controlled trigger fire extinguishing bomb 9 is also included. The electric-controlled trigger fire extinguishing bomb 9 is suspended on the hanging frame 2. The electric-controlled trigger fire extinguishing bomb 9 is controlled by the main controller 1. Preferably, a dry powder fire extinguishing bomb is used. When the fire extinguishing bomb is released in a relatively closed space, it is conducive to the rapid formation of a high-concentration environment of the dry powder fire extinguishing agent in a limited area, quickly suppressing the combustion reaction, and effectively controlling the spread of the electric vehicle fire. The dry powder fire extinguishing bomb is filled with a dry powder fire extinguishing agent, the main components of which are sodium bicarbonate, ammonium phosphate, etc. When extinguishing a fire, the dry powder is sprayed out by the driving gas (usually nitrogen, etc.) in the container. The dry powder fire extinguishing agent itself does not Like carbon dioxide, it will quickly vaporize from liquid to a large amount of gas. The volume of gas expanded during operation is relatively small and will not burst the fire curtain 41. Since the lithium battery of an electric vehicle has a high energy density and relatively active chemical properties, once thermal runaway causes a fire, the development speed is relatively fast. Usually, a small explosion may occur within 1-5 minutes after the signs of fire appear, and a large-scale flame may be ejected within 3-10 minutes. The interval time may be shorter under the influence of conditions. If two electronically controlled fire extinguishing bombs 9 are provided and can be triggered asynchronously, the explosion or flame ejection can be better suppressed.

[0074] The lower end face of the hanging frame 2 is provided with a circle of equally spaced hanging rings 21, and the top of the fire curtain 41 is provided with a curtain head, and the curtain head is provided with a circle of equally spaced upper slits 412. The hanging rings 21 correspond to the upper slits 412 one by one and are provided with a second steel wire rope 6 that passes through them in sequence to connect them, wherein the second steel wire rope 6 is connected head to tail, and the length of the head and tail of the second steel wire is 10-30cm, and the connection of the second steel wire is located on the outside of the fire curtain 41. When the firefighters arrive at the scene and need to remove the fire curtain 41, they only need to separate the head and tail of the second steel wire and pull out the fire curtain 41, which is very convenient, and the reserved second steel wire can act as a buffer when the fire curtain 41 drops rapidly, reducing the impact on the fixed structure of the hanging frame 2 and avoiding structural damage and the falling of the fire curtain 41.

[0075] Reference Figure 10 As shown, another embodiment, which differs from the above embodiment, is that at least two solenoid valves 8 are installed on the hanging frame 2, and the water spray nozzles 7 can be divided into two groups and connected to different solenoid valves 8 respectively, one group spraying water outward and the other group spraying water inward. The fire identification component 3 includes a positioning camera that can identify the specific parking space on fire among multiple parking spaces. While extinguishing the fire in the burning parking space, the main controller can release the surrounding adjacent fire curtains, causing them to fall to further protect the surrounding vehicles. The main controller can also control the water spray nozzles 7 that spray water outward to open, which can spray water on the fire curtains of adjacent parking spaces, but will not trigger the electronically controlled fire extinguishing bombs 9 on the unburned parking spaces. This can reduce the direct impact of the fire on the fire curtains to a certain extent, extend the effective fire protection time of the fire curtains, enhance their fire protection effect, and enhance the protection of the surrounding adjacent parking spaces.

[0076] Reference Figure 11 As shown, a control method for a new energy parking space fire arrester device includes the following steps:

[0077] S1. Fire identification component 3 identifies a fire in a vehicle parking space and sends a fire signal to the main controller 1;

[0078] Specifically, the camera smoke and flame recognition device collects images in real time and analyzes and identifies the images. When it is identified that there is a fire in the image, a fire signal is sent to the main controller 1; or when someone discovers a fire at the scene and presses the emergency switch at the scene, the emergency switch sends a fire signal to the main controller 1.

[0079] S2. The main controller 1 controls the release assembly 5 to release the fire curtain 41;

[0080] Specifically, after receiving the fire signal, the main controller 1 transmits high / low level signals to the eight electromagnetic plugs 51 and the electromagnetic valve 8 at the same time, so that they trigger the movable pins to retract and the electromagnetic valve 8 to open for water flow.

[0081] S3 delay 2-5min, the main controller 1 controls the electronic control trigger fire extinguishing bomb 9 open;

[0082] Specifically, a small explosion may usually occur within 1-5 minutes after the appearance of signs of fire, and a large-scale flame spray may occur within 3-10 minutes. Preferably, it is set to transmit a high / low level signal to the electronically controlled trigger fire extinguishing bomb 9 to trigger it after a delay of 4 minutes.

[0083] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
