A garage suspension type rail fire extinguishing robot and method thereof

Abstract

This application discloses a garage-mounted suspended track-type fire extinguishing robot and its method. The robot comprises a main track, a secondary track, an entry track, a traveling vehicle, an automatic folding basket, water spray pipes, a fire-fighting docking mechanism, and a controller. The main track transports the fire-fighting pipes to the burning parking space. The traveling vehicle detaches from the secondary track and enters the entry track, causing the automatic folding basket to unfold and enclose the burning vehicle in a waterproof and fireproof cloth. High-pressure water spray creates an air isolation zone, forming a double-layer isolation effect with the fireproof cloth, while also achieving physical cooling. The rubber sealing ring and the waterproof and fireproof cloth create internal water accumulation, immersing the battery in water, reducing its temperature, controlling the fire, and preventing reignition. Liquid nitrogen is introduced to further lower the internal temperature; the sinking liquid nitrogen also lowers the temperature of the accumulated water, potentially even forming ice water to control the battery temperature. This fire-fighting equipment has a reasonable overall structural design, is easy to operate, highly automated, and has high fire-fighting efficiency, effectively protecting personal and property safety.

Description

Technical Field

[0001] This application belongs to the field of vehicle fire extinguishing technology, specifically relating to a garage-mounted track fire extinguishing robot and its method. Background Technology

[0002] Currently, the number of vehicles on the road is increasing, especially with the popularization of new energy vehicles. As the number of new energy vehicles grows, their safety issues are becoming increasingly prominent. Compared to traditional vehicles, fires in new energy vehicles are mainly caused by battery fires. A fire in a car chassis battery generally occurs in the following stages: Stage 1: 80℃~120℃: Within this temperature range, the solid electrolyte membrane (SEI) in the battery begins to decompose; Stage 2: 150℃~270℃: The separator closes, shrinks, and decomposes, short-circuiting the positive and negative electrodes, and the negative electrode reacts with carbon in the electrolyte. Acid ester solvents undergo side reactions to produce lithium carbonate, ethylene, ethane, and propane, releasing a large amount of heat, causing the temperature of the lithium-ion battery to continue to rise. In the third stage (170℃~450℃), the safety valve opens and gas is ejected. At high temperatures, many reactions occur in the battery, producing various gases. The internal pressure of the battery continues to increase, and the ejected gas ignites and explodes. The ejected gas contains a large amount of flammable gas. When it encounters air and the temperature reaches the ignition point or there is an ignition source, the conditions for combustion are met, and it will ignite and release a large amount of heat, with temperatures reaching as high as 900℃.

[0003] Existing fire extinguishing technologies and equipment generally cool and extinguish fires during the first or second stage of the fire, typically using fire hydrants or fire extinguishers to spray the entire vehicle. However, garages have limited space, making it difficult for specialized fire trucks to enter. Furthermore, the high parking density in garages increases the risk of fire spreading to other vehicles, making firefighting more difficult and dangerous. In particular, the burning of electric vehicle batteries can release toxic substances, endangering the safety of firefighters. Therefore, this application aims to develop an automated fire extinguishing system for vehicles in garages. Summary of the Invention

[0004] In view of the above problems, this application provides a garage-mounted track-mounted fire extinguishing robot and its method, which can effectively isolate the fire source, automatically locate the fire source to carry out fire extinguishing, improve fire extinguishing efficiency, achieve precise fire extinguishing, and ensure the safety of operators.

[0012] In some embodiments, a rubber sealing ring is provided on the lower side of the water spray pipe at the bottom of the automatic folding basket.

[0013] The rubber sealing ring is a hollow ring, and an annular electromagnet is provided inside the rubber sealing ring. The annular electromagnet is a de-energized electromagnet. Each parking space is equipped with an annular iron sheet that matches the annular electromagnet. A ground inductive wire is buried inside the annular iron sheet of each parking space.

[0014] In some embodiments, the fire water supply pipe is provided with a main pipe, a water outlet and a solenoid valve. The main pipe is arranged along the length of the main track. The water outlets are respectively located on the main pipe corresponding to each parking space. The solenoid valve is located on the water outlet. The fire coupling is provided with a lifting motor, a lifting frame and a plug. The lifting motor is located on the support of the secondary track. The lifting frame is connected to the lifting motor. The plug is fixed to the lifting frame and connected to the water outlet.

[0015] In some embodiments, a positioning mechanism is provided between the secondary track and the storage track. The positioning mechanism includes a push rod motor, a plug rod, and a bolt sleeve.

[0016] In some embodiments, the waterproof and fireproof fabric has an exhaust port on its side.

[0017] Secondly, this application provides a suspended track fire extinguishing method for garages, comprising the following steps: S1. When a vehicle enters the parking space, the ground sensor detects whether the vehicle is parked properly. If the vehicle is not parked properly, an alarm is triggered to remind the owner or manager to handle the situation. If a fire is detected in a parking space, a signal is sent to the controller. The positioning switches on the main track and the auxiliary track detect whether the fire-fighting robot is in the initial position on the main track and whether the automatic folding basket is in the retracted state. S2. The secondary track and the trolley are moved together to the corresponding parking space where the fire occurred, and the secondary track is connected to the entry track by the positioning switch; S3. After the positioning mechanism is locked, the lifting frame of the fire hose connector is raised, and the plug is inserted into the water outlet interface to connect with the main pipe of the fire water supply pipe. S4. When the solenoid valve of the fire water supply pipe is opened, the water spray pipe in the automatic folding basket sprays water at high pressure, and the trolley moves away from the sub-track to above the parking space. S5. The positioning switch detects that the car is in position, the locking mechanism is activated, the anchor winch is activated, and the automatic folding basket unfolds downwards under the operation of the wire rope drum. S6. The rubber sealing ring is in contact with the annular iron sheet on the parking space floor. After power is cut off, the de-energized electromagnet attracts and seals the annular iron sheet. S7. The vehicle interior temperature and smoke sensor readings return to normal, and a 20-minute delay water spray countdown is initiated; all mechanisms reset upon completion.

[0018] In some embodiments, after sealing in step S6, water is sprayed for 5-10 minutes, and the liquid nitrogen cooling mechanism is activated to cool the interior; the vehicle interior temperature and smoke sensor readings return to normal, and step S7 is completed.

[0019] The beneficial effects of this application are as follows: This application, through the setting of a main track, a secondary track, an entry track, a traveling crane, an automatic folding basket, a water spray pipe, and a fire-fighting docking mechanism, allows the main track to transport fire-fighting pipes to the fire-prone parking space. The traveling crane detaches from the secondary track and enters the entry track, causing the automatic folding basket to unfold and encase the burning vehicle in a waterproof and fireproof cloth. The high-pressure water spray creates an air isolation zone, forming a double-layer isolation effect with the waterproof and fireproof cloth, while also achieving a physical cooling effect. The rubber sealing ring and the waterproof and fireproof cloth create internal water accumulation, immersing the battery in water, reducing battery temperature, controlling the fire, and preventing reignition. Furthermore, by introducing liquid nitrogen, the internal temperature is lowered; the sinking liquid nitrogen further reduces the temperature of the accumulated water, and may even form ice water, controlling battery temperature. This fire-fighting equipment has a reasonable overall structural design, is easy to operate, has a high degree of automation, and high fire-fighting efficiency, which is beneficial to ensuring personal and property safety.

[0031] Reference Figures 1-9 According to some embodiments of this application, a garage-mounted suspended track fire extinguishing robot includes a main track 1, a secondary track 2, an entry track 3, a trolley 4, an automatic folding basket 5, a water spray pipe 6, a fire docking mechanism 7, and a controller 8. The main track 1 is suspended parallel to the parking spaces 10 in the same row of the garage. The secondary track 2 is slidably suspended below the two main tracks 1. The entry track 3 is suspended above each parking space 10 and docks with one end of the secondary track 2. The trolley 4 is fixed on the secondary track 2. The automatic folding basket 5 is located under the trolley 4 and has at least two folding points. The water spray pipe 6 is arranged in a ring around each folding point and the top of the trolley 4. The components 6 are connected by a flexible hose, and the inner side of the water spray pipe 6 is provided with nozzles 61 at intervals; the fire docking mechanism 7 is provided with a fire water supply pipe 71 and a fire docking connector 72. The fire water supply pipe 71 is suspended above the main rail 1, and the fire docking connector 72 is provided on the secondary rail 2 through a bracket 22 and connected to the water spray pipe 6; the secondary rail 2 and the trolley 4 are respectively provided with drive mechanisms 9 and are respectively connected to the rollers 92 of the main rail 1 and the secondary rail 2; temperature and smoke sensors (not shown) are respectively provided inside the trolley 4 and above the parking space 10; the automatic folding basket 5, the water spray pipe 6, the fire docking mechanism 7, the drive mechanism 9, and the temperature and smoke sensors are electrically connected to the controller 8.

[0032] The fire-fighting robot is hoisted, which does not interfere with the normal operation of the garage and facilitates its later installation and modification. A single unit can be installed in the same row of garages to monitor and handle fires in multiple parking spaces, extending the equipment's range and reducing costs.

[0033] This application uses the main track 1 to transport fire-fighting equipment to each parking space 10, and then the secondary track 2 connects with the entry track 3 to transport the fire-fighting equipment above the burning vehicle. The fire water supply pipe 71 and the fire connector 72 automatically connect to deploy water spraying for fire extinguishing. The automatic folding basket 5 unfolds the water spray pipe 6, forming a multi-level water spray zone from top to bottom, creating a sealed spray wall. This isolates the outside air on one hand, and comprehensively reduces the temperature of the burning vehicle on the other hand, preventing the fire and pollutants from spreading outward.

[0034] The device can be equipped with a slot or limit structure at the initial position of the main track 1 to prevent movement under normal conditions. After the device is started, it can overcome the limit and move.

[0035] According to some embodiments of this application, the main track 1, the secondary track 2, and the loading track 3 are I-beams; the drive mechanism 9 is provided with a connecting plate 91, a roller 92, and a servo motor 93. The roller 92 is provided on at least one side of the main track 1 and the secondary track 2 through the connecting plate 91. The lower end of each connecting plate 91 is locked to the secondary track 2 and the trolley 4 respectively. The servo motor 93 is fixed on the connecting plate 91 and connected to the roller 92. At least two sets of servo motors 93 are provided on the secondary track 2 and the trolley 4 respectively.

[0036] The rollers 92 of the drive mechanism 9 are located within the groove of the I-beam to ensure stable operation. Rollers 92 are installed on both sides of the I-beam and clamped together by connecting plates 91, making the overall structure more stable. Two rollers 92 can be installed on each side and linked to the servo motor 93 via gears to improve operating efficiency.

[0037] The connecting plate 91 and rollers 92 can be positioned at the four corners, or multiple rollers can be installed on a single track to maintain stability and sufficient support. The servo motors 93 can be positioned at all four corners, only on the front two sides, or diagonally. The servo motors 93 can also be geared motors.

[0038] According to some embodiments of this application, the automatic folding basket 5 is provided with a hinge plate 51, a slide rail 52, an anchor 53, and a waterproof and fireproof cloth 54. The hinge plate 51 and the slide rail 52 are provided on the water spray pipes 6 around the automatic folding basket 5. One end of the hinge plate 51 is connected to the water spray pipe 6, and the other end is slidably disposed in the slide rail 52. The hinge plate 51 is hinged in an "X" shape. The anchor 53 is fixed on the trolley 4, and the free end of the anchor rope of the anchor 53 is connected to the water spray pipe 6 at the bottom of the automatic folding basket 5. The waterproof and fireproof cloth 54 is wrapped around the automatic folding basket 5 and on the top.

[0039] The folding basket 5, formed by the hinge plate 51, slide rail 52, and anchor 53, works in conjunction with the water spray pipe 6 to form a foldable frame. The anchor 53 can automatically unfold and retract the folding basket 5. Typically, the automatic unfolding of the folding basket 5 can be achieved under gravity. If the material is relatively light, torsion springs can be equipped at each hinge point to assist in unfolding.

[0040] After the automatic folding basket 5 is unfolded, it fits against the bottom surface and forms a sealed space with the waterproof and fireproof cloth 54.

[0041] The flexible hoses and electrical wires on the automatic folding basket 5 are distributed along the crisscrossing folding lines of the hinge plate 51, so that they bend synchronously when the automatic folding basket 5 is folded up. The bending effect can also be enhanced by installing tank chains or encasing them within flexible corrugated tubing, thus preventing damage.

[0042] Waterproof and fireproof fabric 54 can be used to cover the entire surface with waterproof and fireproof materials as needed, or only the water-accumulating areas can be waterproofed and fireproofed, while the rest can be fireproofed. The water accumulation height is usually 80-120cm. To prevent excessive internal water accumulation, drainage outlets can also be installed at a height of 80-120cm on the waterproof and fireproof fabric 54.

[0043] According to some embodiments of this application, the automatic folding basket 5 is provided with a locking mechanism 55 on its outer side. The locking mechanism 55 is provided with a hook 551, a reset electric cylinder 552 and a locking seat 553. The hook 551 is provided around the traveling trolley 4 through the reset electric cylinder 552. The locking seat 553 is provided on the water spray pipe 6 at the bottom of the automatic folding basket 5. The hook 551 is locked with the locking seat 553 on the water spray pipe 6 after folding.

[0044] The locking mechanism 55 locks the retracted automatic folding basket 5 to prevent it from unfolding when the basket is not in use, thus avoiding obstruction of the garage's normal operation, damage to the vehicle, or other dangers.

[0045] According to some embodiments of this application, the main track 1 and the secondary track 2, the secondary track 2 and the trolley 4, the secondary track 2 and the entry track 3, and the trolley 4 and the entry track 3 are respectively equipped with positioning switches 11.

[0046] Positioning switch 11 is used to locate various positions, ensuring stable operation of the equipment and preventing damage to the equipment.

[0047] According to some embodiments of this application, the traveling tractor 4 also includes a liquid nitrogen cooling mechanism 41. The liquid nitrogen cooling mechanism 41 is provided with a fireproof isolation box 411, a liquid nitrogen tank 412, a liquid nitrogen pipe 413, a liquid nitrogen nozzle 414, and a control valve (not shown). The fireproof isolation box 411 is mounted on a support 22 of the sub-rail 2. The liquid nitrogen tank 412 is sealed inside the fireproof isolation box 411. The liquid nitrogen pipe 413 is located at least at the second folding point at the lower end. The liquid nitrogen tank 412 and the liquid nitrogen pipe 413 are connected by a flexible hose. The liquid nitrogen nozzle 414 is spaced apart inside the liquid nitrogen pipe 413. The control valve is located at the outlet of the liquid nitrogen tank 412.

[0048] The liquid nitrogen cooling mechanism 41 can quickly reduce the temperature at the fire scene, protect battery safety, and rapidly control the fire. Especially for electric vehicles, conventional water is difficult to use for fire extinguishing. Immersing the battery under the vehicle in water and cooling it with ice water can achieve a better cooling effect and extinguish the fire.

[0049] The installation height of liquid nitrogen tube 413 is usually 80-120cm.

[0050] According to some embodiments of this application, the fire-fighting connector 72 is connected to the water spray pipe 6, the liquid nitrogen tank 412 and the liquid nitrogen pipe 413 by a flexible hose, and the flexible hose is located inside the tank chain.

[0051] Fire-fighting connector 72, liquid nitrogen tank 412 and other equipment are parked on the main rail 1 outside the parking space 10 along the auxiliary rail 2. This reduces the support force of the entry rail 3 on the equipment and reduces the entry of fire-prone equipment, thus ensuring equipment safety.

[0052] According to some embodiments of this application, a rubber sealing ring 56 is provided on the lower side of the water spray pipe 6 at the bottom of the automatic folding basket 5.

[0053] On the one hand, it prevents fire-fighting water from spreading, and on the other hand, it allows water to accumulate inside, immersing the battery in water to lower the battery temperature and isolate it from the outside air.

[0054] According to some embodiments of this application, the rubber sealing ring 56 is a hollow ring, and an annular electromagnet (not shown) is provided inside the rubber sealing ring 56. The annular electromagnet is a de-energized electromagnet. Each parking space 10 is embedded with an annular iron sheet 101 that matches the annular electromagnet. A ground inductive wire 102 is embedded inside the annular iron sheet 101 of the parking space 10.

[0055] The annular electromagnet and annular iron plate 101 ensure a sealing effect, and a de-energized electromagnet is used to avoid reducing the adsorption effect due to power failure. The inductive loop 102 is used to detect whether the vehicle is parked properly to avoid damage to the equipment and failure to control the fire in time.

[0056] According to some embodiments of this application, the fire water supply pipe 71 is provided with a main pipe 711, a water outlet 712 and a solenoid valve 713. The main pipe 711 is arranged along the length of the main track 1. The water outlet 712 is respectively provided on the main pipe 711 corresponding to each parking space 10. The solenoid valve 713 is provided on the water outlet 712. The fire connector 72 is provided with a lifting motor 721, a lifting frame 722 and a plug connector 723. The lifting motor 721 is provided on the bracket 22 of the secondary track 2. The lifting frame 722 is connected to the lifting motor 721. The plug connector 723 is fixed to the lifting frame 722 and is connected to the water outlet 712.

[0057] After the water outlet 712 moves to the designated position, it automatically extends and connects with the water outlet 712 of the main pipe 711 fan pipe, opening the solenoid valve 713 to provide fire water.

[0058] According to some embodiments of this application, a positioning mechanism 21 is provided between the secondary track 2 and the storage track 3. The positioning mechanism 21 is provided with a push rod motor 211, a plug rod 212 and a bolt sleeve 213. The push rod motor 211 and the bolt sleeve 213 are arranged opposite to each other on the secondary track 2 and the storage track 3. The plug rod 212 is connected to the push rod motor 211 and is plugged into the bolt sleeve 213.

[0059] The positioning mechanism 21 is used to lock the position between the secondary track 2 and the entry track 3, so that the trolley 4 can be stably and smoothly transported onto the entry track 3.

[0060] The front end of the insertion rod 212 can be set as a tapered head to facilitate insertion into the sleeve 213.

[0061] According to some embodiments of this application, the waterproof and fireproof cloth 54 is provided with an exhaust port 541 on its side.

[0062] The vent can release the gas generated inside in a timely manner, preventing excessive internal pressure, and can also prevent flames from escaping.

[0063] Reference Figures 1-9 According to some embodiments of this application, a garage suspended track fire extinguishing method includes the following steps: S1. When a vehicle enters parking space 10, the ground sensor 102 detects whether the vehicle is parked properly. If the vehicle is not parked properly, an alarm is triggered to remind the owner or manager to handle the situation. If a fire is detected in parking space 10, a signal is sent to the controller 8. The positioning switches 11 of the main track 1 and the auxiliary track 2 detect whether the vehicle is in the initial position of the main track 1 and whether the automatic folding basket 5 is in the folded state. The equipment monitors in real time whether the 10 vehicles in each parking space are parked properly. If they are not parked properly, an alarm is triggered to remind the driver or manager to handle the situation; otherwise, the parking status is normal.

[0064] In the event of a fire, controller 8 receives a fire signal. Before operation, the crane 4 performs a self-check to determine whether it is in the initial position of the main track 1, whether the automatic folding basket 5 is retracted, and whether the burning vehicle is parked in accordance with regulations. If not, it performs relevant reset or alarm processing; otherwise, it proceeds to the next step.

[0065] S2.
