Description

Technical Field

[0001] This invention relates to the field of fire extinguishing technology, specifically a fire extinguishing device with a telescopic cover that is 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 a telescopic 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 carries the frame 1B2 by lifting it with the lifting device 3B. The fire extinguishing device 4 installed on the frame 1B2 includes a fire extinguishing medium 4A and a telescopic cover 5. The telescopic cover 5 includes a telescopic device 5A and a cover device 5B. The cover device 5B includes a retractable body 5B1 and an extended body 5B2 when the telescopic device 5A is retracted in its original state. The retractable body 5B1 does not affect the operation of the AGV trolley 3. When a car 2 in a parking space 1A is found to be in danger of fire or fire, the AGV trolley 3 immediately carries the frame 1B2 to a designated position next to the car 2A. The lifting device 3B descends, placing the frame 1B2 on the ground, and the AGV trolley 3 drives away from the scene. The telescopic device 5A extends, and the retractable body 5B1 unfolds to become the unfolded body 5B2 covering the car 2A. The fire extinguishing device 4 extinguishes the fire using the fire extinguishing medium 4A.

[0007] As a further aspect of the present invention: the AGV trolley 3 includes a high-pressure gas generator 6, and the telescopic device 5A includes two sets of multi-stage cylinders 5A1, which are installed on the AGV body 3A; when the high-pressure gas generated by the high-pressure gas generator 6 enters the multi-stage cylinders 5A1, the multi-stage cylinders 5A1 extend rapidly.

[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; when the pyrotechnic explosive 6A1 is ignited, the high-pressure gas generated therefrom can rapidly extend the multi-stage cylinder 5A1.

[0009] As a further aspect of the present invention: the cover device 5B includes a membrane fold cover 7, and the membrane fold cover 7 includes a high-temperature resistant membrane 7A.

[0010] As a further aspect of the present invention: the membrane folding cover 7 is U-shaped and inverted on the AGV body 3A. The membrane 7A includes a top folding membrane 7A1 located at the top and side folding membranes 7A2 located at the front and rear ends of the AGV body 3A. The multi-stage cylinder 5A1 is located between the top folding membrane 7A1 and the side folding membranes 7A2. The bottom edge of the side folding membrane 7A2 includes several drooping blocks 7A2A. After the multi-stage cylinder 5A1 extends, the side folding membrane 7A2 hangs down naturally through the drooping blocks 7A2A and covers both sides of the emergency vehicle 2A.

[0011] As a further aspect of the present invention: the membrane 7A includes a front folding membrane 7A3 located at the front end of one side of the AGV body 3A, and the telescopic device 5A includes an upper crossbar 5A2, a lowering bar 5A3, and a locking device 8. The two ends of the upper crossbar 5A2, located between the top folding membrane 7A1 and the front folding membrane 7A3, are respectively connected to the front ends of two sets of multi-stage cylinders 5A1. In the original state, the two ends of the lowering bar 5A3, which is installed at the bottom of the front folding membrane 7A3, are connected to the upper crossbar 5A2 through the locking device 8. When the multi-stage cylinder 5A1 extends to the bottom, the locking device 8 is activated, causing the lowering bar 5A3 to unlock and disengage from the upper crossbar 5A2. The lowering bar 5A3 then hangs down by its own weight, and the front folding membrane 7A3 and the side folding membrane 7A2 together form a cover to shield the dangerous vehicle 2A.

[0012] As a further aspect of the present invention: the multi-stage cylinder 5A1 is located outside the junction of the top folded membrane 7A1 and the side folded membrane 7A2. The top folded membrane 7A1 and the side folded membrane 7A2 have the same cross-sectional view, that is, the number of folds and the height after folding are the same in the cross-sectional view. The top folded membrane 7A1 includes top folding angles 7A1A located on both sides of the bottom, and the side folded membrane 7A2 includes side folding angles 7A2B located at the top of the inner side. In the planar unfolded view of the top folded membrane 7A1 and the side folding membrane 7A2, the top folding angles 7A1A and 7A2B are connected.

[0013] As a further embodiment of the present invention: the locking device 8 includes a pin 8A, a hook 8B, a rope 8C, a front fixing end 8D of the rope and a tail fixing end 8E of the rope. The pin 8A is installed at the front end of the upper crossbar 5A2 or the multi-stage cylinder 5A1, and the hook 8B and the upper crossbar 5A2 are hinged together by the pin 8A. One end of the rope 8C is connected to the hook 8B, and the other end is fixed to the cylinder seat of the multi-stage cylinder 5A1. In the original state when the multi-stage cylinder 5A1 is not extended, the upper crossbar 5A2 hooks the lower bar 5A3 through the hook 8B, and the front folding film 7A3 is folded between the upper crossbar 5A2 and the lower bar 5A3. When the multi-stage cylinder 5A1 extends to the set position, the hook 8B is pulled by the rope 8C, and the hook 8B rotates around the pin 8A to unlock. The lower bar 5A3 falls by its own weight, so that the front folding film 7A3 covers one end of the dangerous vehicle 2A.

[0014] 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, the width of the membrane folding cover 7 is equal to the width of the parking space 1A, the top surface of the frame 1B2 is higher than the height of the car 2, and the membrane 7A includes a rear membrane 7A4 located on the fire-facing side of the frame 1B2.

[0015] As a further aspect of the present invention: the fire extinguishing medium 4A includes perfluorohexanone, foam, water-based, water-based and heptafluoropropane.

[0016] Compared with traditional technologies, this invention has the following characteristics: First, it equips the parking garage with unmanned AGVs, which can carry fire extinguishing equipment to the vehicle in distress in the shortest possible time; Second, it cleverly designs a multi-stage cylinder and creatively adopts an explosive high-pressure gas generator, which can push out the multi-stage cylinders one by one in a very short time, covering the vehicle in distress and isolating it from the surrounding environment; Third, as soon as 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 in a high-temperature environment.

[0017] In summary, for fire extinguishing in parking garages, this invention has three major advantages: rapid response, precise positioning, and fire suppression with a covering effect. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1-13 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 carries the frame 1B2 by lifting it with the lifting device 3B. The fire extinguishing device 4 installed on the frame 1B2 includes a fire extinguishing medium 4A and a telescopic cover 5. The telescopic cover 5 includes a telescopic device 5A and a cover device 5B. The cover device 5B includes a retractable body 5B1 and an extended body 5B2 when the telescopic device 5A is retracted in its original state. The retractable body 5B1 does not affect the operation of the AGV trolley 3. When a car 2 in a parking space 1A is found to be in danger of fire or fire, the AGV trolley 3 immediately carries the frame 1B2 to a designated position next to the car 2A. The lifting device 3B descends, placing the frame 1B2 on the ground, and the AGV trolley 3 drives away from the scene. The telescopic device 5A extends, and the retractable body 5B1 unfolds to become the unfolded body 5B2 covering the car 2A. The fire extinguishing device 4 extinguishes the fire using the fire extinguishing medium 4A.

[0022] It should be noted that the fire extinguishing device 4 with a telescopic cover can be used in places other than parking garage 1, and other specific objects can also be set as cars 2.

[0023] It should also be noted that extinguishing medium 4A can be released by gas or by a pump.

[0024] The AGV trolley 3 includes a high-pressure gas generator 6, and the telescopic device 5A includes two sets of multi-stage cylinders 5A1, which are installed on the AGV body 3A. When the high-pressure gas generated by the high-pressure gas generator 6 enters the multi-stage cylinders 5A1, the multi-stage cylinders 5A1 extend rapidly.

[0025] The high-pressure gas generating device 6 includes an explosive gas generating device 6A, which includes a pyrotechnic explosive 6A1. When the pyrotechnic explosive 6A1 is ignited, the high-pressure gas generated can quickly extend the multi-stage cylinder 5A1.

[0026] It should be further 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.

[0027] The aforementioned cover device 5B includes a membrane fold cover 7, which includes a high-temperature resistant membrane 7A.

[0028] The membrane folding cover 7 is U-shaped and inverted on the AGV body 3A. The membrane 7A includes a top folding membrane 7A1 at the top and side folding membranes 7A2 at the front and rear ends of the AGV body 3A. The multi-stage cylinder 5A1 is located between the top folding membrane 7A1 and the side folding membranes 7A2. The bottom edge of the side folding membrane 7A2 includes several drooping blocks 7A2A. After the multi-stage cylinder 5A1 extends, the side folding membrane 7A2 hangs down naturally through the drooping blocks 7A2A and covers both sides of the dangerous vehicle 2A.

[0029] It should be noted that the side-folded membrane 7A2 can be a flexible membrane. When the side-folded membrane 7A2 encounters obstacles such as car mirrors or cars parked crookedly, it will not affect the forward extension of the side-folded membrane 7A2.

[0030] The membrane 7A includes a front folding membrane 7A3 located at the front end of one side of the AGV body 3A. The telescopic device 5A includes an upper crossbar 5A2, a lower bar 5A3, and a locking device 8. The two ends of the upper crossbar 5A2, located between the top folding membrane 7A1 and the front folding membrane 7A3, are respectively connected to the front ends of two sets of multi-stage cylinders 5A1. In the original state, the two ends of the lower bar 5A3, which is installed at the bottom of the front folding membrane 7A3, are connected to the upper crossbar 5A2 through the locking device 8. When the multi-stage cylinder 5A1 extends to the bottom, the locking device 8 is activated, which unlocks and disengages the lower bar 5A3 from the upper crossbar 5A2. The lower bar 5A3 then hangs down by its own weight, and the front folding membrane 7A3 and the side folding membrane 7A2 together form a cover to shield the vehicle 2A in danger.

[0031] The multi-stage cylinder 5A1 is located outside the junction of the top folded membrane 7A1 and the side folded membrane 7A2. The top folded membrane 7A1 and the side folded membrane 7A2 have the same cross-sectional view, that is, the number of folds and the height after folding are the same in the cross-sectional view. The top folded membrane 7A1 includes top folding angles 7A1A located on both sides of the bottom, and the side folded membrane 7A2 includes a side folding angle 7A2B located at the top of the inner side. In the planar unfolded view of the top folded membrane 7A1 and the side folding membrane 7A2, the top folding angle 7A1A and the side folding angle 7A2B are connected.

[0032] The locking device 8 includes a pin 8A, a hook 8B, a rope 8C, a front fixing end 8D of the rope, and a tail fixing end 8E of the rope. The pin 8A is installed at the front end of the upper crossbar 5A2 or the multi-stage cylinder 5A1, and the hook 8B and the upper crossbar 5A2 are hinged together by the pin 8A. One end of the rope 8C is connected to the hook 8B, and the other end is fixed to the cylinder seat of the multi-stage cylinder 5A1. In the original state when the multi-stage cylinder 5A1 is not extended, the upper crossbar 5A2 hooks the lower bar 5A3 through the hook 8B, and the front folding film 7A3 is folded between the upper crossbar 5A2 and the lower bar 5A3. When the multi-stage cylinder 5A1 extends to the set position, the hook 8B is pulled by the rope 8C, and the hook 8B rotates around the pin 8A to unlock. The lower bar 5A3 falls by its own weight, so that the front folding film 7A3 covers one end of the dangerous vehicle 2A.

[0033] The length of the frame 1B2 is slightly greater than the width of the parking space 1A, the width of the membrane fold cover 7 is equal to the width of the parking space 1A, the top surface of the frame 1B2 is higher than the height of the car 2, and the membrane 7A includes a rear membrane 7A4 located on the fire-facing side of the frame 1B2.

[0034] It should be noted that the AGV body 3A can be the same length as the frame 1B2.

[0035] The fire extinguishing medium 4A includes perfluorohexanone, foam, water-based, water-based and heptafluoropropane.

[0036] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. In this invention, it should also be noted that the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integrally formed connection, a mechanical connection, or an indirect connection through an intermediate medium. The specific meaning of the terms in this invention can be understood according to the specific circumstances.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
