Description

Technical Field

[0001] This invention relates to the field of fire extinguishing technology, specifically a fire extinguishing device with an airbag carried by an AGV vehicle. Background Technology

[0002] Traditional fire extinguishing techniques have the following drawbacks for fires inside parking garages: 1. When the fire department receives a fire alarm in a parking garage, even if fire trucks are dispatched immediately, by the time they arrive at the scene, the fire has often already escalated into a large-scale blaze, especially in underground garages. Due to poor ventilation, the dense smoke generated by the fire can quickly spread throughout the entire garage. Once inside an underground garage, fire truck drivers not only cannot see the exact location of the fire, but their lives are also threatened.

[0003] Second, the proportion of electric vehicles is constantly increasing, while the fire extinguishing agents sprayed by the sprinkler fire extinguishing systems installed in existing parking garages are water. However, water as a fire extinguishing medium is not suitable for fires caused by batteries.

[0004] Third, traditional fire extinguishing techniques are more suitable for open spaces, but their fire extinguishing effect is very poor for parking garages. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a fire extinguishing device with an airbag cover that is carried by an AGV vehicle, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The parking garage 1 includes parking spaces 1A, a fire protection system 1B, and vehicles 2. The fire protection system 1B includes a frame 1B2, an AGV trolley 3, and a fire extinguishing device 4. The AGV trolley 3 includes an AGV body 3A and a lifting device 3B installed on the AGV body 3A. The AGV trolley 3, through the lifting device 3B, can lift the frame 1B2 off the ground and carry the frame 1B2 during operation. The fire extinguishing device 4 installed on the frame 1B2 includes a fire extinguishing medium 4A, an airbag cover 5, and a high-pressure gas generator 6. The airbag cover 5 includes a contracted body 5A before being inflated by the high-pressure gas generator 6 and an expanded body 5B after being inflated by the high-pressure gas generator 6. When it is discovered that car 2 in a parking space 1A has become a fire or a car 2A in danger of fire, the AGV trolley 3 immediately carries the frame 1B2 to the position set next to the car 2A in danger, the lifting device 3B descends, so that the frame 1B2 is placed on the ground, and the AGV trolley 3 drives away from the scene. When the high-pressure gas generator 6 is activated, the contraction body 5A is inflated by the high-pressure gas generator 6 and pops out, unfolding into an expansion body 5B that covers the dangerous vehicle 2A. The fire extinguishing device 4 extinguishes the fire through the fire extinguishing medium 4A.

[0007] As a further aspect of the present invention: the high-pressure gas generating device 6 includes an internal high-pressure gas generating device wrapped within a shrink body 5A and an external high-pressure gas generating device mounted on a frame 1B2.

[0008] As a further aspect of the present invention: the high-pressure gas generating device 6 includes an explosive gas generating device 6A, which includes a pyrotechnic explosive 6A1; after the pyrotechnic explosive 6A1 is ignited, the high-pressure gas generated therefrom can transform the contractile body 5A into an expandable body 5B.

[0009] As a further aspect of the present invention: the fire extinguishing medium 4A includes an internal fire extinguishing medium wrapped within a shrink body 5A and an external fire extinguishing medium installed on a frame 1B2.

[0010] As a further aspect of the present invention: the airbag cover 5 includes a membrane cover 5C.

[0011] As a further aspect of the present invention: the length of the frame 1B2 is slightly greater than the width of the parking space 1A, and the width of the membrane cover 5C is equal to the width of the parking space 1A.

[0012] As a further aspect of the present invention: the membrane cover 5C includes a beam-column membrane cover 7, which includes an inflatable beam 7A, an inflatable column 7B, a top membrane 7C, a side membrane 7D, and a front membrane 7E; after the beam-column membrane cover 7 expands into an inflatable body 5B, the horizontal inflatable beam 7A and the vertical inflatable column 7B support the cover with the opening facing downward, which is composed of the top membrane 7C and the side membrane 7D, and the tubular inflatable beam 7A and the inflatable column 7B are connected.

[0013] As a further aspect of the present invention: the top surface of the frame 1B2 is higher than the height of the car, and the beam-column membrane cover 7 includes a rear membrane 7F located on the fire-facing side of the frame 1B2.

[0014] Compared with traditional technologies, this invention has the following characteristics: First, it equips the parking garage with driverless AGVs that can carry fire extinguishing equipment to the vehicle in distress in the shortest possible time; Second, it creatively invented an airbag cover with a minimalist structure that can open in a very short time to cover the vehicle in distress and isolate it from the surrounding environment; Third, once the AGV is lowered from the frame, it quickly leaves the scene, avoiding secondary fires that may occur due to the power supply carried by the AGV itself being exposed to high temperatures.

[0015] In summary, this invention has three major advantages in fire fighting and rescue operations within parking garages: rapid response, precise positioning, and fire suppression by covering the fire. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-7 In this embodiment of the invention, the parking garage 1 includes parking spaces 1A, a fire protection system 1B, and cars 2. The fire protection system 1B includes a frame 1B2, an AGV trolley 3, and a fire extinguishing device 4. The AGV trolley 3 includes an AGV body 3A and a lifting device 3B installed on the AGV body 3A. The AGV trolley 3 can lift the frame 1B2 off the ground and carry the frame 1B2 while running by lifting it through the lifting device 3B. The fire extinguishing device 4 installed on the frame 1B2 includes a fire extinguishing medium 4A, an airbag cover 5, and a high-pressure gas generator 6. The airbag cover 5 includes a contracted body 5A before being inflated by the high-pressure gas generator 6 and an expanded body 5B after being inflated by the high-pressure gas generator 6. When it is discovered that car 2 in a parking space 1A has become a fire or a car 2A in danger of fire, the AGV trolley 3 immediately carries the frame 1B2 to the position set next to the car 2A in danger, the lifting device 3B descends, so that the frame 1B2 is placed on the ground, and the AGV trolley 3 drives away from the scene. When the high-pressure gas generator 6 is activated, the contraction body 5A is inflated by the high-pressure gas generator 6 and pops out, unfolding into an expansion body 5B that covers the dangerous vehicle 2A. The fire extinguishing device 4 extinguishes the fire through the fire extinguishing medium 4A.

[0020] It should be noted that: the fire extinguishing device with an airbag can be used in places other than parking garage 1, and other specific objects can also be set as car 2; the fire extinguishing device 4 can start to operate after the contraction body 5A becomes the expansion body 5B, or it can start to operate before the contraction body 5A becomes the expansion body 5B; the fire extinguishing medium 4A can be released by gas or by pump.

[0021] The high-pressure gas generating device 6 includes an internal high-pressure gas generating device wrapped inside the shrink body 5A and an external high-pressure gas generating device mounted on the frame 1B2.

[0022] The high-pressure gas generating device 6 includes an explosive gas generating device 6A, which includes a pyrotechnic explosive 6A1. After the pyrotechnic explosive 6A1 is ignited, the high-pressure gas it generates can transform the contractile body 5A into an expandable body 5B.

[0023] It should be noted that the high-pressure gas generator 6 can also be a high-pressure gas generator based on the same principle as a car airbag.

[0024] The fire extinguishing medium 4A includes an internal fire extinguishing medium enclosed within a shrink body 5A and an external fire extinguishing medium mounted on a frame 1B2.

[0025] It should be noted that extinguishing medium 4A can be perfluorohexanone or foam, or it can be water-based or water-based, or it can be heptafluoropropane.

[0026] The airbag cover 5 includes a membrane cover 5C.

[0027] It should be noted that the membrane cover 5C can be composed of a high-temperature resistant flexible membrane. Because the membrane is flexible, it will not affect the forward extension of the membrane cover 5C when it encounters obstacles such as car reflectors or cars parked crookedly.

[0028] The length of the frame 1B2 is slightly greater than the width of the parking space 1A, and the width of the membrane cover 5C is equal to the width of the parking space 1A.

[0029] It should be noted that the AGV body 3A can also be the same length as the frame 1B2.

[0030] The membrane cover 5C includes a beam-column membrane cover 7, which includes an inflatable beam 7A, an inflatable column 7B, a top membrane 7C, a side membrane 7D, and a front membrane 7E. After the beam-column membrane cover 7 expands into an inflatable body 5B, the horizontal inflatable beam 7A and the vertical inflatable column 7B support the downward-facing cover composed of the top membrane 7C and the side membrane 7D. The tubular inflatable beam 7A and the inflatable column 7B are connected.

[0031] The top surface of the frame 1B2 is higher than the height of the car, and the beam-column membrane cover 7 includes a rear membrane 7F located on the fire-facing side of the frame 1B2.
