Description

Technical Field

[0001] This invention relates to the field of fire extinguishing device technology, and more specifically, to an emergency fire extinguishing device for the accumulation of flammable materials in a warehouse. Background Technology

[0002] With social development, my country's logistics industry has grown rapidly. In the logistics industry, warehousing is a crucial link in ensuring the safety and rapid flow of goods. As warehouse capacity increases, the amount of goods stored in warehouses also increases, often including high-value items. Due to the dense concentration of goods and the presence of many flammable materials, warehouses are prone to fires. Once a warehouse fire destroys goods, it will cause huge losses to logistics companies and cargo owners. To cope with warehouse fires, fire-fighting measures are usually implemented. However, existing warehouse fire extinguishing devices are often obstructed by piled-up goods, resulting in less than ideal fire-fighting effects. Furthermore, the fire-fighting methods are limited, generally relying on a single spraying of extinguishing agents, which only extinguishes the open flames on the surface of the fire, thus the fire-fighting effectiveness needs improvement. Therefore, it is necessary to provide an emergency fire-fighting device for the accumulation of flammable materials in warehouses to solve the problems mentioned in the background. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: an emergency fire extinguishing device for flammable material accumulation in a warehouse, comprising:

[0004] Fixed tracks are installed at the top of the warehouse;

[0005] A mobile device that can be moved and mounted on a fixed track, and can move or stop on the fixed track;

[0006] The motor is fixed to the moving device by a mounting plate.

[0007] The drive component, located within the mobile device, is connected to the motor;

[0008] The ejection assembly is located inside the drive assembly;

[0009] The fire extinguisher is located inside the mobile device and is connected to the ejection assembly;

[0010] The spraying device is fixedly connected to the drive assembly.

[0011] Furthermore, preferably, the mobile device includes:

[0012] Multiple movable clamping blocks are arranged in a ring and are set on the inner wall of the movable device. A connecting member is provided between the movable clamping blocks to connect the inner wall of the movable device and the middle part of the spraying device. The connecting member is a hollow structure.

[0013] The water supply pipe connects to an external pipeline at one end and passes through a connector at the other end to the sprinkler system. In other words, when the mobile device moves the entire fire extinguishing system, the range of movement of the mobile device is affected by the length of the water supply pipe; that is, the water supply pipe cannot detach from the external pipeline.

[0014] Furthermore, preferably, the movable clamping block includes:

[0015] The drive shaft is located at one end of the movable clamping block near the center of the moving device and passes through the movable clamping block;

[0016] The transmission gears are symmetrically distributed and fixed at both ends of the transmission shaft;

[0017] A smooth surface is located on the top of the moving clamping block, adjacent to the drive shaft;

[0018] The threaded surface is positioned adjacent to the smooth surface.

[0019] Furthermore, preferably, the driving component includes:

[0020] The upper rotating shaft is rotatably mounted inside the moving device, and its bottom is provided with a thread that is opposite to the threaded surface in the moving clamping block;

[0021] A bevel gear set connects the rotating shaft and the motor;

[0022] The lower rotating shaft is coaxially arranged with the upper rotating shaft and is located below the moving clamping block;

[0023] The internal gear ring is located on the inner wall of the upper and lower rotating shafts, corresponding to the transmission gears at both ends of the transmission shaft. That is, when the motor drives the bevel gear set to rotate, it in turn drives the upper rotating shaft to rotate. Then, under the action of the thread at the bottom of the upper rotating shaft, the movable clamping block moves outward. With the continuous movement of the movable clamping block, at the point where the smooth surface contacts the upper rotating shaft, and the transmission gear on the transmission shaft meshes with the internal gear ring, the upper rotating shaft and the movable clamping block are in a slipping state. That is, the movable clamping block remains stationary, and the upper rotating shaft drives the transmission gear to rotate via the internal gear ring, which in turn drives the lower rotating shaft to rotate. The lower rotating shaft then drives the spraying device to rotate and spray.

[0024] Furthermore, preferably, the ejection assembly includes:

[0025] The upper limit plate is slidably connected to the inner wall of the upper rotating shaft.

[0026] The storage column is fixed to the upper limit plate;

[0027] A high-strength spring is installed inside the upper rotating shaft and is fixedly connected to the upper limit plate at the top.

[0028] The lower limit plate is connected to a high-strength spring at the top and is secured to the fire extinguisher at the bottom. When the motor drives the upper rotating shaft to rotate, it simultaneously drives the upper limit plate to rotate. Under the action of the fire extinguisher, the lower limit plate is in a fixed state. In turn, the upper limit plate drives the high-strength spring to rotate and compress. As the high-strength spring is compressed, the storage column moves downward with the upper limit plate.

[0029] Furthermore, preferably, the fire extinguisher includes:

[0030] Gun tip;

[0031] The gun body passes through the middle of the spray device and is located inside the lower rotating shaft;

[0032] The gun tail is secured at the top by the lower limit plate, and has a slide corresponding to the transmission gear at the bottom.

[0033] The hose is housed within the storage column and passes through the ejection assembly to connect to the tail of the gun;

[0034] A replacement column, located above the storage column and connected to the hose, has multiple through holes on its outer wall, and its diameter is the same as that of the gun tail. When the motor drives the upper rotating shaft to rotate, the gun tail is held in a fixed state by the moving clamping block and the transmission gear. Under the continuous rotation of the upper rotating shaft, the high-strength spring in the ejection assembly is compressed. As the moving clamping block moves outward until it detaches from the gun tail, the fire extinguisher is ejected by the lower limit plate under the action of the high-strength spring, which in turn drives the hose and replacement column to move rapidly downward, passing through the ejection assembly and the lower rotating shaft. The total length from the fire extinguisher head to the replacement column is less than the distance from the spray device to the ground. Under the action of ejection and the fire extinguisher's own gravity, the hose and replacement column are driven downward, while the head is given sufficient impact force to penetrate the cargo and reach the center of the fire to extinguish the smoldering fire.

[0035] Furthermore, preferably, the gun body is provided with multiple annularly distributed water spray holes, and two sets of symmetrically distributed support plates cover the outside of the water spray holes. One end of each support plate is connected to the gun body via a torsion assembly, and the other end is fixed to the outer wall of the gun body via a plastic ring. When the fire extinguisher reaches the interior of the fire point, the plastic ring softens due to heat, and the two sets of support plates spring up to both sides under the action of the torsion assemblies on both sides, supporting the cargo and exposing the water spray holes, expanding the space around the fire extinguisher to facilitate water jetting for fire extinguishing.

[0036] Furthermore, preferably, the spraying device includes:

[0037] The rotating component is fixedly connected to the lower rotating shaft.

[0038] The water injection component is rotatably connected to the rotating component, and is connected to the inner wall of the moving device through a connector. The water injection component is also connected to the water supply pipe.

[0039] A circular seal is located on the inner ring of the water injection component, corresponding to the replacement column and having the same diameter. When the fire extinguisher is inside the mobile device and connected to the ejection assembly, the spraying device remains fixed and continuously supplies water to the water injection component under the action of the water supply pipe, spraying through the rotating component. When the fire extinguisher is ejected, the replacement column is pulled downward by the fire extinguisher, thereby ejecting the circular seal. The replacement column then seals the water injection component in place of the circular seal. At the same time, water flows through the through-hole on the outer wall of the replacement column into the hose, and then sprays out through the spray holes on the gun body to extinguish the internal smoldering fire. Simultaneously, the lower rotating shaft rotates under the action of the transmission gear, thereby driving the rotating component to rotate, forming a circular spray surface to quickly extinguish external open flames.

[0040] Compared with the prior art, the beneficial effects of the present invention are:

[0041] In this invention, the mobile device allows the entire fire extinguishing system to move within a certain range, enabling it to be moved above the point of ignition for firefighting. This effectively avoids obstruction by cargo, thus preventing the fire extinguishing effect from being affected. Furthermore, with the cooperation of the fire extinguishing gun and the spray device, both open flames and smoldering fires can be extinguished simultaneously, preventing reignition and reducing economic losses.

[0047] Please see Figs. 1-4 In this embodiment of the invention, an emergency fire extinguishing device for warehouse flammable material accumulation includes:

[0048] Fixed track 1 is installed on the top of the warehouse;

[0049] The mobile device 2 is movably mounted on the fixed track 1 and can move or stop on the fixed track 1;

[0050] Motor 3 is fixed to the moving device 2 by a fixing plate;

[0051] The drive component 4 is located inside the moving device 2 and is connected to the motor 3;

[0052] The ejection assembly 5 is located inside the drive assembly 4;

[0053] Fire extinguisher 6 is installed inside the mobile device 2 and connected to the ejection assembly 5;

[0054] The spraying device 7 is fixedly connected to the drive assembly 4.

[0055] In this embodiment, the mobile device 2 includes:

[0056] Multiple movable clamping blocks 21 are arranged in a ring and are set on the inner wall of the movable device 2. A connector is provided between the movable clamping blocks 21 to connect the inner wall of the movable device 2 and the middle part of the spraying device 7. The connector is a hollow structure.

[0057] The water supply pipe 22 is connected to an external pipeline at one end and passes through a connector at the other end to the sprinkler device 7. In other words, when the mobile device 2 moves the entire fire extinguishing device, the range of movement of the mobile device 2 is affected by the length of the water supply pipe 22, meaning that the water supply pipe 22 cannot be detached from the external pipeline.

[0058] In this embodiment, the movable clamping block 21 includes:

[0059] The drive shaft 211 is located at one end of the movable clamping block 21 near the center of the moving device 2 and passes through the movable clamping block 21;

[0060] The transmission gears 212 are symmetrically distributed and fixed at both ends of the transmission shaft 211;

[0061] A smooth surface 213 is disposed on the top of the movable clamping block 21 and is adjacent to the drive shaft 211;

[0062] The threaded surface 214 is disposed adjacent to the smooth surface 213.

[0063] In this embodiment, the driving component 4 includes:

[0064] The upper rotating shaft 41 is rotatably disposed inside the moving device 2, and its bottom is provided with a thread opposite to the threaded surface 214 in the moving clamping block 21;

[0065] The bevel gear set 42 connects the upper rotating shaft 41 and the motor 3;

[0066] The lower rotating shaft 43 is coaxially arranged with the upper rotating shaft 41 and is located below the movable clamping block 21;

[0067] The internal gear ring 44 is disposed on the inner wall of the upper rotating shaft 41 and the lower rotating shaft 43, corresponding to the transmission gears 212 at both ends of the transmission shaft 211. That is, when the motor 3 drives the bevel gear set 42 to rotate, it in turn drives the upper rotating shaft 41 to rotate. Then, under the action of the bottom thread of the upper rotating shaft 41, the moving clamping block 21 moves outward. With the continuous movement of the moving clamping block 21, the smooth surface 213 contacts the upper rotating shaft 41, and the transmission gear 212 on the transmission shaft 211 meshes with the internal gear ring 44. At this time, the upper rotating shaft 41 and the moving clamping block 21 are in a slipping state, that is, the moving clamping block 21 remains stationary. The upper rotating shaft 41 drives the transmission gear 212 to rotate through the internal gear ring 44, and then drives the lower rotating shaft 43 to rotate through the transmission shaft 211. The lower rotating shaft 43 drives the spraying device 7 to rotate and spray.

[0068] In this embodiment, the ejection assembly 5 includes:

[0069] The upper limit plate 51 is slidably connected to the inner wall of the upper rotating shaft 41;

[0070] Storage column 52 is fixed on upper limit plate 51;

[0071] A high-strength spring 53 is installed inside the upper rotating shaft 41, and its top is fixedly connected to the upper limit plate 51.

[0072] The lower limit plate 54 is connected to the high-strength spring 53 at the top and is locked onto the fire extinguisher 6 at the bottom. When the motor 3 drives the upper rotating shaft 41 to rotate, it also drives the upper limit plate 51 to rotate. Under the action of the fire extinguisher 6, the lower limit plate 54 is in a fixed state. Then, the upper limit plate 51 drives the high-strength spring 53 to rotate and compress. As the high-strength spring 53 is compressed, the storage column 52 moves down with the upper limit plate 51.

[0073] In this embodiment, the fire extinguisher 6 includes:

[0074] Gunhead 61;

[0075] The gun body 62 passes through the middle of the spray device 7 and is located inside the lower rotating shaft 43;

[0076] The gun tail 63 is topped on the lower limit plate 54 and bottom is provided with a slide corresponding to the transmission gear 212;

[0077] The flexible hose 64 is installed inside the storage column 52 and passes through the ejection assembly 5 to connect with the gun tail 63;

[0078] A replacement column 65 is located above the storage column 52 and connected to the hose 64. The outer wall of the replacement column 65 has multiple through holes, and the diameter of the replacement column 65 is the same as the diameter of the gun tail 63. When the motor 3 drives the upper rotating shaft 41 to rotate, the gun tail 63 is restricted by the moving clamping block 21 and the transmission gear 212 and remains fixed. Under the continuous rotation of the upper rotating shaft 41, the high-strength spring 53 in the ejection assembly 5 is compressed. As the moving clamping block 21 moves outward until it is separated from the gun tail 63, the fire extinguishing gun 6 is ejected by the lower limit plate 54 under the action of the high-strength spring 53. This causes the hose 64 and the replacement column 65 to move down quickly, passing through the ejection assembly 5 and the lower rotating shaft 43. The total length from the gun head 61 to the replacement column 65 of the fire extinguishing gun 6 is less than the distance from the spray device 7 to the ground. Under the action of ejection and the gravity of the fire extinguishing gun 6 itself, the hose 64 and the replacement column 65 are moved down, while the gun head 61 is given sufficient impact force to penetrate the cargo and reach the center of the fire to extinguish the smoldering fire.

[0079] In this embodiment, the gun body 62 is provided with multiple annularly distributed water spray holes, and two sets of symmetrically distributed support plates 622 are covered on the outside of the water spray holes. One end of the support plate 622 is connected to the gun body 62 via a torsion assembly 621, and the other end is fixed to the outer wall of the gun body 62 via a plastic ring 623. When the fire extinguishing gun 6 reaches the interior of the fire point, the plastic ring 623 softens due to heat, and the two sets of support plates 622 spring up to both sides under the action of the torsion assemblies 621 on both sides, supporting the cargo and exposing the water spray holes at the same time, expanding the space around the fire extinguishing gun 6 to facilitate water jet for fire extinguishing.

[0080] In this embodiment, the spraying device 7 includes:

[0081] The rotating component 71 is fixedly connected to the lower rotating shaft 43;

[0082] The water injection component 72 is rotatably connected to the rotating component 71, and is connected to the inner wall of the moving device 2 through a connector. The water injection component 72 is also connected to the water supply pipe 22.

[0083] A circular seal 73 is located in the inner ring of the water injection component 72, corresponding to the replacement column 65 and having the same diameter. When the fire extinguishing gun 6 is located inside the moving device 2 and connected to the ejection assembly 5, the spraying device 7 remains fixed and continuously supplies water to the water injection component 72 under the action of the water supply pipe 22, spraying through the rotating component 71; when the fire extinguishing gun 6 is ejected, the replacement column 65 is pulled down by the fire extinguishing gun 6, thereby ejecting the circular seal 73, and the replacement column 65 replaces the circular seal 73 to seal the water injection component 72. At the same time, the water flows through the through hole in the outer wall of the replacement column 65 into the hose 64, and then sprays out through the spray hole on the gun body 62 to extinguish the internal smoldering fire. At the same time, the lower rotating shaft 43 rotates under the action of the transmission gear 212, thereby driving the rotating component 71 to rotate, forming a circular spray surface to quickly extinguish the external open flame.

[0084] In practice, the warehouse is first divided into zones for the installation of fire extinguishing devices. The water supply pipe 22 ensures water delivery during the movement of the fire extinguishing devices. When flammable materials in the warehouse catch fire, the fire extinguishing device, under the action of the moving device 2, moves to above the fire point via the fixed track 1. At this time, the water supply pipe 22 delivers water to the water injection component 72, which sprays through the rotating component 71. Simultaneously, the motor 3 drives the upper rotating shaft 41 to rotate via the bevel gear set 42, compressing the high-strength spring 53 in the ejection assembly 5. This also drives the moving clamping block 21 to move outwards, gradually disengaging from the gun tail 63. When the moving clamping block 21 disengages from the gun tail 63... The fire extinguisher 6 is ejected under the action of the high-strength spring 53, which simultaneously drives the hose 64 and the replacement column 65 to move. When the replacement column 65 moves to the center position of the spray device 7, under the influence of the pulling force of the fire extinguisher 6, the replacement column 65 ejects the circular seal 73 and replaces the position of the circular seal 73. The water flows through the through hole in the outer wall of the replacement column 65 into the hose 64, and then is sprayed out by the fire extinguisher 6. At this time, in addition to the fire extinguisher 6 being ejected, the lower rotating shaft 43 rotates under the drive of the transmission gear 212, which in turn drives the rotating component 71 to rotate, forming a circular spray surface, which evenly covers the fire point with water and extinguishes the external open flames. During this process, due to the presence of the connecting parts, the water injection component 72 remains fixed under the action of the moving device 2. After the fire extinguisher 6 enters the cargo, the plastic ring 623 softens due to the temperature, and the support plate 622 pops up, expanding the space around the fire extinguisher 6 to facilitate water spraying and extinguishing the smoldering fire. The fire is extinguished both inside and outside at the same time, thus completing the fire extinguishing work.

[0085] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
