[0002] Forest fires in mountainous areas often cause massive losses of resources and property, environmental pollution, and even casualties. Currently, forest firefighting requires specialized firefighters and equipment such as fire trucks, sprinklers, and fire extinguishers to extinguish the fire. However, in practice, most of this equipment is bulky and difficult to carry, and is generally ineffective for extinguishing large forest fires, resulting in a lack of efficient firefighting tools. Furthermore, sprinklers and fire extinguishers consume rapidly during continuous firefighting, requiring emergency resupply. This can easily lead to missed opportunities for fire control and fire spread. Therefore, those skilled in the art have provided a forest fire safety extinguishing device to address the issues raised in the aforementioned background technology. Summary of the Invention

[0036] See also Figure 1 In an embodiment of the present invention, a forest fire prevention and safety fire extinguishing device includes:

[0037] An outer frame 11, one end of which is connected to a fire protection engineering vehicle (not shown);

[0038] A transfer arm 12 is rotatably connected to the outer frame 11, and a connecting shaft 13 is rotatably provided at one end of the transfer arm 12;

[0039] The fireproof cover 1 is fixed below the connecting shaft 13;

[0040] A fire-fighting and weeding mechanism 2 is installed in the middle of the lower end surface of the fireproof cover 1. The fire-fighting and weeding mechanism 2 can vertically press the cover on the fire source point and simultaneously chain-cut the hay, branches and leaves and flammable materials at the fire source point; and

[0041] The soil covering component 3 is arranged below the fireproof cover 1, wherein the fire-fighting engineering vehicle can extinguish fires from various points of forest fire sources and form a fire isolation zone. The soil covering component can effectively separate flammable materials such as forest hay, branches and leaves from the fire source, avoid secondary combustion, achieve the fire control stage in the initial fire extinguishing, and block the fire head.

[0042] In this embodiment, the fire extinguishing and weeding mechanism 2 includes:

[0043] An upper cover 21 is fixed above the fireproof cover 1;

[0044] An inner frame plate 22 is transversely fixed in the fireproof cover 1 by bolts, and an intermediate shaft 23 is rotatably provided on the inner frame plate 22;

[0045] A drive gear holder (not shown) is fixed in the upper hood 21. One end of the intermediate shaft 23 is fixed to the drive gear holder and is driven to rotate by the drive gear holder. A main gear 25 is sleeved on the intermediate shaft 23.

[0046] A positioning frame 24 is fixed below the inner frame plate 22. A plurality of rotating shafts 27 are distributed circumferentially on the positioning frame 24. Each rotating shaft 27 is sleeved with a driven gear, and the driven gear meshes with the main gear 25 for transmission.

[0047] a fire extinguishing disk 26 fixed on each of the rotating shafts 27; and

[0048] The fire extinguishing chain 4 is connected to each of the fire extinguishing discs 26. That is to say, when the adapter arm controls the fire extinguishing and weeding mechanism to be pressed down, the intermediate shaft drives the fire extinguishing discs on each rotating shaft to rotate through the column gear, thereby fully separating the burning materials in the hay covering the fire source point and reducing the fire.

[0049] As a preferred embodiment, a flow cavity is provided in the intermediate shaft 23, and a plastic sleeve 210 is sealed and rotatably sleeved on the end of the intermediate shaft 23. One end of the plastic sleeve 210 is connected to an external water pipe 29, and a nozzle 28 is fixed below the intermediate shaft 23. The nozzle 28 is sealedly connected to the flow cavity, so that water supply and cooling can be coordinated in the pressure cover of the fire source to quickly extinguish the fire.

[0050] In this embodiment, there are multiple positioning holes distributed circumferentially on the fire extinguishing disk 26, and each of the fire fighting chains 4 is slidably inserted into the positioning holes. The rotating shaft 27 adopts a hollow shaft tube structure, and an inner connecting rod 41 is slidably arranged in the rotating shaft 27. A strip-shaped through-hole is provided on the rotating shaft 27, and one end of the fire fighting chain 4 passes through the strip-shaped through-hole and is connected to the inner connecting rod 41. An annular cylinder 42 is fixed on the positioning frame 24, and an annular plunger 43 is slidably arranged in the annular cylinder 42. A plurality of guide sleeves 44 are vertically fixed below the annular plunger 43, and one end of each inner connecting rod 41 passes through the annular cylinder 42 and is rotatably connected to the guide sleeve 44. An air pressure pipe is connected to the annular cylinder 42, wherein the air pressure pipe drives the annular plunger to slide vertically under the air supply pressure. At this time, each inner connecting rod can make each fire fighting chain slide out of the fire extinguishing disk under displacement, and the fire extinguishing disk can be rotated by the fire fighting chain to extinguish the fire under the rotation action.

[0051] In this embodiment, the fire-fighting chain 4 is provided with a serrated groove, and the length of the fire-fighting chain 4 relative to the fire-extinguishing disk 26 is in the range of 8 cm to 35 cm. In particular, the serrated groove on the fire-fighting chain can cut and remove flammable materials such as hay, branches and leaves at the fire source, isolate the fire source, and reduce the spread of the fire. In order to avoid the fire-fighting chain from being too long and causing entanglement, the initial extension length of the fire-fighting chain is controlled (less than 15 cm), and then the fire-extinguishing disk is gradually extended through the vertical displacement of the inner connecting rod.

[0052] In this embodiment, the soil covering component 3 includes:

[0053] The outer ring seat 31 is coaxially fixed on the fireproof cover 1;

[0054] Multiple telescopic adjustment rods 32 are distributed circumferentially, and one end of each telescopic adjustment rod 32 is universally hinged below the outer ring seat 31;

[0055] A connecting ring frame 33 is provided in the fireproof cover 1, and one end of the telescopic adjustment rod 32 is connected to the connecting ring frame 33;

[0056] A fixed shaft disc 34 is rotatably mounted on the connecting ring frame 33 , a drive motor 35 is mounted on the connecting ring frame 33 , and an output end of the drive motor 35 is connected to the fixed shaft disc 34 via a transmission chain for transmission; and

[0057] The soil cutting frame 36 is circumferentially distributed below the fixed shaft disc 34 .

[0058] As a preferred embodiment, the connecting ring frame 33 can be deflected within the range of 0° to 15° under the cooperation of the telescopic adjustment rod 32, so that the fixed shaft disk can intercept the carbon soil at the fire source through the soil cutting frame during rotation, and can diffuse the carbon soil in the fireproof cover during circular rotation, further achieving the effect of isolating oxygen, and at the same time maintain the humidity of the carbon soil when mixed with fire water (flowing out of the nozzle) so as to cool the fire source and extinguish the fire, while reducing the evaporation of fire water, reducing water consumption, and improving the continuity of fire extinguishing.

[0059] In this embodiment, the cutting frame 36 is rotatably connected to the fixed shaft disc 34, so that a plurality of the cutting frames 36 can be arranged at different angles on the fixed shaft disc 34, thereby realizing step-by-step excavation.

[0060] Specifically, in the initial stage of forest fire extinguishing, multiple fire-fighting engineering vehicles can carry out firefighting at various points of the forest fire source in order to block the fire head, control the fire, and avoid missing the best time to control the fire. Among them, the fire-fighting and weeding mechanism can cover the fire source point, and the fire-fighting chain can gradually extend as the fire-fighting disc rotates, so as to cut and weed flammable materials such as branches and leaves at the fire source point, and cooperate with the soil covering component to cover the fire source point with carbon soil to achieve a rapid fire extinguishing effect, and at the same time form a fire line in the forest fire source area to prevent the fire source from expanding and spreading.

[0061] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
