[0002] In recent years, affected by global warming, forest fires have become increasingly frequent, causing enormous economic losses and casualties. Benefiting from the development of my country's science and technology and overall national strength, forest fire fighting has gradually shifted from the traditional "human-based" method to a more mechanized and modern approach. With the continuous development of equipment and technical tactics, ground-air coordinated operations are being used more frequently to better cope with the complex forest fire environment. Therefore, using aerial means to drop fire extinguishing bombs has become one of the main methods of forest fire fighting.

[0003] Most existing sprinkler fire extinguishing devices use handheld nozzles to extinguish fires in the affected area. However, because the area that the nozzles can spray is limited, the direction of the nozzles needs to be frequently changed, making it difficult to quickly spray a large area of ​​fire, resulting in low fire extinguishing efficiency. Summary of the Invention

[0012] Preferably, the triggering mechanism includes a fixed tube inserted through the bottom end of the outer cylinder, a trigger rod inserted inside the fixed tube, a return spring movably sleeved on the outside of the trigger rod, one end of the return spring being fixed to the outside of the trigger rod, and the other end of the return spring being fixed to the upper end face of the fixed tube;

[0013] The trigger rod has two deflection rods symmetrically hinged to its side. A T-shaped hinge rod is hinged to the end of the deflection rod away from the trigger rod. The lower end of the vertical rod of the T-shaped hinge rod is fixed to the top of the fixed tube.

[0014] The fixed tube is provided with a limiting slide tube on the outside. A first double ring pressure plate is slidably connected to the outside of the limiting slide tube. The outside of the first double ring pressure plate slides on the inner wall of the inner tube. The first double ring pressure plate is movably sleeved on the outside of the fixed tube.

[0016] Preferably, the inner spraying mechanism includes a return spring telescopic tube that is snapped onto the other end of the T-shaped hinge rod crossbar, and the upper end of the return spring telescopic tube is fixed on the top surface of the outer cylinder. The return spring telescopic tube is slidably connected to the limiting slide tube with a second double ring pressure plate, and a protruding post is fixedly connected to the side of the second double ring pressure plate. The protruding post abuts against the wave-shaped slide groove opened on the inner wall of the inner tube.

[0017] A sealing disc is movably sleeved on the upper end of the return spring telescopic tube, and the sealing disc is fixed on the upper side of the inner wall of the inner tube. A rigid tube is hinged on the sealing disc, and a connecting rope is connected between the rigid tube and the return spring telescopic tube. A second flexible nozzle is provided inside the rigid tube, and the water inlet end of the second flexible nozzle is fixed in the water outlet at the upper end of the sealing disc. The rigid tube is fixedly connected to the upper end of the return spring telescopic tube.

[0018] Preferably, a second one-way valve is fixedly connected to the bottom surface of the inner wall of the outer cylinder, and the outlet end of the second one-way valve is inside the inner tube.

[0019] Preferably, both the first double-ring pressure plate and the second double-ring pressure plate are made of two hollow discs nested together, and a connecting block is fixedly connected between the two hollow discs.

[0020] Preferably, the method of using the aforementioned forest sprinkler fire extinguishing equipment includes the following steps:

[0021] S1: When the user is extinguishing a fire, the outer cylinder is lifted by the drone and moved to the fire area by the traction rope. Then the traction rope is separated from the drone. At this time, the third spring telescopic rod drives the upper pressure plate to move down under its own extension force. The liquid stored between the upper and lower pressure plates is transported to the lower side of the lower pressure plate through the first one-way valve. At this time, the pressure in the outer cylinder under the lower pressure plate increases and is sprayed out through the first hose nozzle in the hinge pipe. Since the outlet of the hinge pipe is downward, the water inside the outer cylinder is sprayed in an umbrella shape through multiple first hose nozzles during the fall, so that the water in the outer cylinder sprays water over a large area to the fire area.

[0022] When the outer cylinder falls to the ground, the support plate is deflected by the force, squeezing the L-shaped bracket to deflect, causing one end of it to separate from the protrusion at the bottom of the second spring telescopic rod. At this time, the support plate retracts and pulls the first spring telescopic rod at one end to deflect, causing the gear on one end to move the first spring telescopic rod on the other gear to deflect clockwise, causing the water nozzle of the hinge pipe to tilt upward, so that the first hose nozzle sprays water in a flower shape, ensuring the fire extinguishing effect of the first hose nozzle spraying water.

[0023] S2: When the upper pressure plate moves down and touches one end of the spring telescopic tube, the spring telescopic tube releases the restriction on the fourth spring telescopic rod. At this time, the fourth spring telescopic rod continues to extend and pushes the lower pressure plate down, relaying the remaining water in the outer cylinder to be sprayed out through the first hose nozzle.

[0024] Furthermore, when the outer cylinder lands, the trigger rod is forced to move upward, causing the crossbar of the T-shaped hinge rod on the deflection rod to deflect, so that the two ends of the crossbar of the T-shaped hinge rod are separated from the return spring telescopic tube and the locking block respectively. At this time, the first double ring pressure plate moves downward under the action of the tension spring return force, squeezing the water on the lower side of the inner tube from the second one-way valve and spraying water into the area at the bottom of the outer cylinder.

[0025] S3: Then the return spring telescopic tube retracts, and when the return spring telescopic tube retracts, the second double ring pressure plate on its lower end moves up. At this time, the convex post abuts against the corrugated slide groove, causing the corrugated slide groove to drive the inner tube to rotate clockwise and counterclockwise, causing the rigid tube on its upper end surface to swing left and right, causing the second flexible hose nozzle inside the rigid tube to swing and spray water, ensuring that the second flexible hose nozzle sprays water in a flower-shaped pattern, and the water pressure inside the second flexible hose nozzle is greater, and its spray area is farther. The second flexible hose nozzle cooperates with the first flexible hose nozzle to ensure its fire extinguishing effect in the area centered on the outer cylinder; and when the inner tube rotates clockwise and counterclockwise, the connecting rope on the return spring telescopic tube is passively wrapped around one end of the inner tube and then reset, causing the rigid tube to deflect and swing, increasing the spray distance of the second flexible hose nozzle inside the rigid tube.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] In this invention, the upper pressure plate is moved downward by the third spring telescopic rod under its own elongation force, and the liquid stored between the upper and lower pressure plates is transported to the lower side of the lower pressure plate through the first one-way valve. At this time, the pressure in the outer cylinder on the lower side of the lower pressure plate increases and is sprayed out through the first hose nozzle in the hinge pipe. Since the outlet of the hinge pipe is downward, the water inside the outer cylinder is sprayed in an umbrella shape through multiple first hose nozzles during the falling process, so that the water in the outer cylinder can spray water over a large area to the fire area.

[0028] In this invention, when the outer cylinder falls to the ground, the support plate is deflected by the force, squeezing the L-shaped bracket to deflect, causing one end of it to separate from the protrusion at the bottom of the second spring telescopic rod. At this time, the support plate retracts and pulls the first spring telescopic rod at one end to deflect, causing the gear on one end to move the first spring telescopic rod on the other gear to deflect clockwise, causing the water nozzle of the hinge pipe to tilt upward, so that the first hose nozzle sprays water in a flower shape, ensuring the fire extinguishing effect of the first hose nozzle spraying water.

[0029] In this invention, when the outer cylinder lands, the trigger rod is forced upward, causing the crossbar of the T-shaped hinge rod on the deflection rod to deflect, so that the two ends of the crossbar of the T-shaped hinge rod are separated from the return spring telescopic tube and the locking block, respectively. At this time, the first double ring pressure plate moves downward under the action of the tension spring return force, squeezing the water on the lower side of the inner tube from the second one-way valve and spraying water into the area at the bottom of the outer cylinder.

[0030] In this invention, when the return spring telescopic tube retracts, the second double-ring pressure plate on its lower end moves upward. At this time, the protrusion abuts against the corrugated groove, causing the corrugated groove to drive the inner tube to rotate clockwise and counterclockwise, causing the rigid tube on its upper end surface to swing left and right. This causes the second flexible nozzle inside the rigid tube to swing and spray water, ensuring that the second flexible nozzle sprays water in a flower-like pattern. Moreover, the water pressure inside the second flexible nozzle is greater, and its spraying area is farther. The second flexible nozzle cooperates with the first flexible nozzle to ensure the fire extinguishing effect in the area centered on the outer cylinder. When the inner tube rotates clockwise and counterclockwise, the connecting rope on the return spring telescopic tube is passively wrapped around one end of the inner tube and then reset, causing the rigid tube to deflect and swing, increasing the spraying distance of the second flexible nozzle inside the rigid tube.

[0057] The method of use and advantages of this invention: The working process of this forest sprinkler fire extinguishing device is as follows:

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown:

[0059] S1: When the user is extinguishing a fire, the drone 47 lifts the outer cylinder 1 with the traction rope 48 and moves it to the fire area. Then the traction rope 48 is separated from the drone 47. At this time, the third spring telescopic rod 41 drives the upper pressure plate 42 to move down under its own extension force. The liquid stored between the upper pressure plate 42 and the lower pressure plate 45 is transported to the lower side of the lower pressure plate 45 through the first one-way valve 46. At this time, the pressure in the outer cylinder 1 under the lower pressure plate 45 increases and is sprayed out through the first hose nozzle 22 in the hinge pipe 21. Since the outlet of the hinge pipe 21 is downward, the water inside the outer cylinder 1 is sprayed in an umbrella shape through multiple first hose nozzles 22 during the fall, so that the water in the outer cylinder 1 sprays water to the fire area over a large area.

[0060] When the outer cylinder 1 falls to the ground, the support plate 26 is deflected by the force, squeezing the L-shaped bracket 25 to deflect, causing one end of it to separate from the protrusion at the bottom of the second spring telescopic rod 28. At this time, the support plate 26 retracts and pulls the first spring telescopic rod 23 at one end to deflect, causing the gear 24 on one end to move the first spring telescopic rod 23 on the other gear 24 to deflect clockwise, causing the water nozzle of the hinge pipe 21 to tilt upward, so that the first hose nozzle 22 sprays water in a flower shape, ensuring the fire extinguishing effect of the first hose nozzle 22 spraying water.

[0061] S2: When the upper pressure plate 42 moves down and touches one end of the spring telescopic tube 44, the spring telescopic tube 44 releases the restriction on the fourth spring telescopic rod 43. At this time, the fourth spring telescopic rod 43 continues to extend and pushes the lower pressure plate 45 down, relaying the remaining water in the outer cylinder 1 to be sprayed out through the first hose nozzle 22.

[0062] Furthermore, when the outer cylinder 1 lands, the trigger rod 52 is forced to move upward, causing the crossbar of the T-shaped hinge rod 54 on the deflection rod 57 to deflect, so that the two ends of the crossbar of the T-shaped hinge rod 54 are separated from the return spring telescopic tube 61 and the locking block 59 respectively. At this time, the first double ring pressure plate 56 moves downward under the action of the return force of the tension spring 58, squeezing the water on the lower side of the inner tube 3 out of the second one-way valve 7 and spraying water into the area at the bottom of the outer cylinder 1.

[0063] S3: Then the return spring telescopic tube 61 retracts, and when the return spring telescopic tube 61 retracts, the second double ring pressure plate 62 on its lower end moves upward. At this time, the protrusion 63 abuts against the wave-shaped slide groove 64, causing the wave-shaped slide groove 64 to drive the inner tube 3 to rotate clockwise and counterclockwise, causing the rigid tube 67 on its upper end surface to swing left and right, causing the second flexible hose nozzle 66 inside the rigid tube 67 to swing and spray water, ensuring that the second flexible hose nozzle 66 sprays water in a flower-shaped pattern, and the water pressure inside the second flexible hose nozzle 66 is greater, and its spray area is farther. The second flexible hose nozzle 66 cooperates with the first flexible hose nozzle 22 to ensure its fire extinguishing effect in the area centered on the outer cylinder 1; and when the inner tube 3 rotates clockwise and counterclockwise, the connecting rope on the return spring telescopic tube 61 is passively wrapped around one end of the inner tube 3 and then resets, causing the rigid tube 67 to deflect and swing, increasing the spray distance of the second flexible hose nozzle 66 inside the rigid tube 67.

6. A method for using a forest sprinkler fire extinguishing system, comprising the following steps: S1: When extinguishing a fire, the user uses a drone (47) to lift the outer cylinder (1) with a traction rope (48) and move it to the area where the fire occurred. Then, the traction rope (48) is separated from the drone (47). At this time, the third spring telescopic rod (41) drives the upper pressure plate (42) to move down under its own elongation force, and the liquid stored between the upper pressure plate (42) and the lower pressure plate (45) is transported to the lower side of the lower pressure plate (45) through the first one-way valve (46). At this time, the pressure in the outer cylinder (1) under the lower pressure plate (45) increases and is sprayed out through the first hose nozzle (22) in the hinge pipe (21). At this time, since the outlet of the hinge pipe (21) is downward, the water inside the outer cylinder (1) is circulated during the falling process. Multiple first hose nozzles (22) spray in an umbrella shape, allowing the water in the outer cylinder (1) to spray water over a large area of ​​the fire area; when the outer cylinder (1) falls to the ground, the support plate (26) is deflected by the force, squeezing the L-shaped bracket (25) to deflect, causing one end of it to separate from the protrusion at the bottom of the second spring telescopic rod (28). At this time, the support plate (26) retracts and pulls the first spring telescopic rod (23) at one end to deflect, causing the gear (24) on one end to move the first spring telescopic rod (23) on another gear (24) to deflect clockwise, causing the water nozzle of the hinge pipe (21) to tilt upward, so that the first hose nozzle (22) sprays water in a flower shape, ensuring the fire extinguishing effect of the first hose nozzle (22); S2: When the upper pressure plate (42) moves down and touches one end of the spring telescopic tube (44), the spring telescopic tube (44) releases the restriction on the fourth spring telescopic rod (43). At this time, the fourth spring telescopic rod (43) continues to extend and pushes the lower pressure plate (45) down, relaying the remaining water in the outer cylinder (1) through the first hose nozzle (22). When the outer cylinder (1) lands, the trigger rod (52) is forced to move up and drives the cross bar of the T-shaped hinge rod (54) on the deflection rod (57) to deflect, so that the two ends of the cross bar of the T-shaped hinge rod (54) are separated from the reset spring telescopic tube (61) and the locking block (59) respectively. At this time, the first double ring pressure plate (56) moves down under the action of the reset force of the tension spring (58), squeezing the water on the lower side of the inner tube (3) from the second one-way valve (7) and spraying water into the area at the bottom of the outer cylinder (1). S3: Then the return spring telescopic tube (61) retracts, and when the return spring telescopic tube (61) retracts, the second double ring pressure plate (62) on its lower end moves upward. At this time, the protrusion (63) abuts against the wave-shaped slide groove (64), causing the wave-shaped slide groove (64) to drive the inner tube (3) to rotate clockwise and counterclockwise, causing the rigid tube (67) on its upper end surface to swing left and right, causing the second flexible hose nozzle (66) inside the rigid tube (67) to swing and spray water, ensuring that the second flexible hose nozzle (66) sprays water in a flower-like pattern, and The second hose nozzle (66) has a higher water pressure inside and sprays water over a longer area. The second hose nozzle (66) works in conjunction with the first hose nozzle (22) to ensure the fire extinguishing effect within the area centered on the outer cylinder (1). When the inner tube (3) rotates clockwise and counterclockwise, the connecting rope on the return spring telescopic tube (61) is passively wrapped around one end of the inner tube (3) and then resets, causing the rigid tube (67) to deflect and swing, increasing the spraying distance of the second hose nozzle (66) inside the rigid tube (67).
