[Specific implementation method]

[0024] Example:

[0025] Please refer to Figure 1-Figure 4 The present embodiment is an automatic fire extinguishing device 100, which includes a frame 1, an enclosure shell 3 arranged on the frame 1 and surrounding a fire extinguishing chamber 2, a sliding door 4 located at one side of the enclosure shell 3 and closing or opening the fire extinguishing chamber 2 by moving up and down, a fire blanket 5 located above the fire extinguishing chamber 2 and moving up and down, and a sand falling unit 6 located above the fire blanket 5. The interior of the fire extinguishing chamber 2 is also provided with a blowing pipe 7 for blowing air into the fire extinguishing chamber 2, and the top of the fire extinguishing chamber 2 is provided with an air outlet pipe 8 connected to the outside.

[0026] The bottom surface of the fire extinguishing chamber 2 is provided with a plurality of support plates 28 distributed in parallel and used to support the burning goods, and a space is formed between two adjacent support plates 28. When a forklift forks a pallet with the burning goods into the fire extinguishing chamber 2, the pallet is placed on the support plates 28. The space between the support plates 28 can provide a good avoidance space for the bottom fork of the forklift, so that the pallet can be placed on the support plates 28 smoothly and conveniently.

[0027] This embodiment further includes a fan (not shown in the figure), which is arranged at the bottom of the frame 1, and the output end of the fan is connected to the blowing pipe 7. The blowing pipe 7 is arranged at a lower position of the fire extinguishing chamber 2, and a plurality of blowing ports are arranged on the blowing pipe 7. By blowing air into the fire extinguishing chamber 2, the residual smoke and heat generated by the fire can be quickly blown upward from the bottom and discharged through the air outlet pipe 8.

[0028] A first cylinder 10 for driving the sliding door 4 to move up and down is arranged on the frame 1 outside the enclosure housing 3. Two first cylinders 10 are arranged and are located on both sides of the sliding door 4. A first chain 11 is connected to the movable end of the first cylinder 10. The first chain 11 is wound around a first sprocket shaft 12 and the other end is connected to the sliding door 4 through a connecting plate. Through the telescopic movement of the first cylinder 10, the sliding door 4 can move up and down under the transmission action of the first chain 11.

[0029] A second cylinder 14 is provided on the frame 1 outside the enclosure shell 3 to drive the fire blanket 5 to move up and down. A connecting plate 15 is connected to the movable end of the second cylinder 14, and the connecting plate 15 is fixedly connected to one side of a second chain 16. The second chain 16 is in a closed structure and is wound around one side of a pair of second sprocket shafts 18 distributed vertically. The up and down movement of both sides of the second chain 16 is achieved through the telescopic movement of the second cylinder 14. The connecting plate 15 is slidably arranged on a slide rail 25 through a slider 24.

[0030] A third chain (not shown in the figure) is wound around the other side of the second sprocket shaft 18, a pair of vertically distributed third sprocket shafts (not shown in the figure) are arranged on the column on the same side of the second sprocket shaft 18 on the frame 1, a pair of vertically distributed fourth sprocket shafts 19 are arranged on the column on the opposite side of the second sprocket shaft 18, and a pair of vertically distributed fifth sprocket shafts 20 are arranged on the column on the diagonal side of the second sprocket shaft 18. The second sprocket shaft 18 is connected to the fourth sprocket shaft 19 on the opposite side through a transmission shaft 17 to achieve synchronous rotation transmission of the two. The fourth sprocket shaft 19 is sleeved with a fourth chain 21. A fifth chain 22 is wound between the second sprocket shaft 18 and the third sprocket shaft to connect them as a whole, and a sixth chain 23 is wound around the fourth sprocket shaft 19 and the fifth sprocket shaft 20 to connect them as a whole. The synchronous movement of the chain group is achieved by setting multiple groups of sprocket shafts and chains and the transmission shaft.

[0031] The fire blanket 5 is fixed on a rectangular frame fixture 26 around its periphery, so as to facilitate the replacement of the fire blanket 5. The rectangular frame fixture 26 is connected to the vertical distribution edges of the third chain, the fourth chain 21, the sixth chain 23, and the fifth chain 22 through connecting plates at the four corners, and moves up and down along with the vertical edges of the above four chains.

[0032] The sand falling unit 6 includes a sand storage bin 61, a sand baffle 62 disposed at the sand outlet at the lower end of the sand storage bin 61, and a third cylinder 63 for driving the sand baffle 62 to perform horizontal linear motion. A supporting structure 64 is disposed at the bottom of the sand baffle 62 to support the sand baffle 62 so that the sand baffle 62 performs telescopic motion on the surface of the supporting structure 64 to open or close the sand outlet. The third cylinder 63 is disposed on the outer side of the enclosure housing 3.

[0033] A sensor 27 is also provided in the fire extinguishing chamber 2 for detecting whether there is any cargo entering the fire extinguishing chamber 2 .

[0034] When goods are on fire, the corresponding burning pallet is placed in the fire extinguishing chamber 2, and the sliding door 4 is driven downward by the first cylinder 10 to close. The sensor 27 in the fire extinguishing chamber 2 detects the goods, and the second cylinder 14 is started to drop the fire blanket 5, which covers the surface of the goods. The upper sand baffle 62 is opened, and the sand in the sand storage bin 61 falls and covers the surface of the fire blanket 5, wrapping the goods and isolating oxygen to extinguish the fire. At the same time, the fan below is turned on to supply air to the fire extinguishing chamber 2 through the blower pipe 7, and the residual smoke and heat of the fire are quickly discharged through the air outlet pipe 8 to achieve the purpose of extinguishing the fire.

[0035] The automatic fire extinguishing device 100 of this embodiment only needs to put the corresponding fire tray into the box to ensure fire extinguishing, without the need for manual fire extinguishing, which reduces the danger, saves time, and will not cause secondary losses; and all cylinder driving mechanisms are arranged outside the fire extinguishing chamber, and a chain transmission mechanism is arranged in the fire extinguishing chamber to realize the up and down movement of the fire blanket, which can effectively protect the cylinder from damage and ensure the operating stability of the pneumatic driving mechanism, thereby ensuring the effective implementation of the fire extinguishing operation and increasing the service life of the fire extinguishing box.

[0036] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
