Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to a fire-fighting unmanned aerial vehicle. Background Art

[0002] A wildfire may be caused by just a small spark, which can cause irreversible consequences. Forest fires are sudden, destructive, and extremely difficult to handle and extinguish. Once they occur, they pose a great threat to the safety of life and property. Forest fire is the most dangerous enemy of the forest and the most terrible disaster in the forestry industry. It will bring the most harmful and devastating consequences to the forest.

[0003] In the prior art, when a forest fire occurs, in order to reduce the pressure on fire brigade personnel and ensure the safety of firefighters, the fire brigade will use drones equipped with fire extinguishing bombs to extinguish the forest fire. However, when the existing drones are equipped with fire extinguishing bombs, it is necessary to install a fire extinguishing bomb carrier under the drone. When the fire extinguishing bomb carrier is small, the number of fire extinguishing bombs carried is small, which affects the effect of forest fire extinguishing. When the fire extinguishing bomb carrier is large, after all the fire extinguishing bombs are dropped, the overall weight of the drone becomes lighter, and the fire extinguishing bomb carrier is subject to greater wind resistance, which can easily cause the drone to shake, thereby affecting the safety of the drone's flight. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that when a forest fire occurs, in order to reduce the pressure on fire brigade personnel and ensure the safety of firefighters, the fire brigade will use drones equipped with fire extinguishing bombs to extinguish forest fires. However, when the existing drones are equipped with fire extinguishing bombs, it is necessary to install a fire extinguishing bomb carrier under the drone. When the fire extinguishing bomb carrier is small, the number of fire extinguishing bombs carried is small, which affects the effect of forest fire extinguishing. When the fire extinguishing bomb carrier is large, after all the fire extinguishing bombs are released, the overall weight of the drone becomes lighter, and the fire extinguishing bomb carrier is subject to greater wind resistance, which can easily cause the drone to shake, thereby affecting the safety of the drone flight.

[0006] Preferably, one end of the two compression springs 2 are symmetrically fixedly installed on the bottom of the disc 1, and the other end of the two compression springs 2 are symmetrically fixedly installed on the top of the disc 2. The other ends of the two movable rods 1 are fixedly sleeved with a limiting ring. Under the restoring force of the compression springs 2, when the pressure on the disc 2 caused by the weight of the fire extinguishing bomb is reduced, the movable rod 1 can drive the disc 2 to move upward.

[0010] Preferably, two guide bars are symmetrically fixedly installed on the inner wall of the hollow rotating rod, and two guide grooves are symmetrically opened on the outer surface of the solid rotating rod. The outer surfaces of the two guide bars are movably embedded in the two guide grooves respectively. Through the setting of the guide bars and the guide grooves, the solid rotating rod can slide up and down along the inside of the hollow rotating rod, and can rotate along with the rotation of the hollow rotating rod.

[0011] Preferably, the outer surface of the hollow rotating rod near the top and the outer surface of the solid rotating rod near the bottom are both fixedly sleeved with a circular ring, and two round rods are symmetrically fixedly installed on the outer surfaces of the two circular rings, and a triangular block 1 is fixedly installed at one end of a plurality of the round rods, and a plurality of balls are movably embedded in the inclined surfaces of a plurality of the triangular blocks 1, and a triangular block 2 is fixedly installed at the bottom of a plurality of the baffle plates, and the circular ring, the round rod and the triangular block 1 are rotated around the central axis of the hollow rotating rod so that the balls contact the inclined surface of the triangular block 2 and squeeze it, and the friction of the triangular block 2 can be reduced by the setting of the balls. Since the triangular block 1 and the triangular block 2 are both set in a triangular shape, the triangular block 2 is subjected to an upward force, thereby driving the baffle plate to move upward.

[0012] Preferably, the tops of the disc one and the disc two are provided with a plurality of anti-deviation members in a circular array, and the plurality of anti-deviation members respectively correspond to the plurality of delivery holes, and the bottom of the disc one is provided with a plurality of guide members in a circular array, and the outer surfaces of the plurality of guide members close to the bottom are fixedly sleeved with rings, and the outer surfaces of the plurality of rings are fixedly installed with support rods, and one ends of the plurality of support rods are respectively fixedly installed on one side of a plurality of shielding plates close to the bottom, and when the shielding plates move upward, the support rods and the rings can be driven upward synchronously, so that the guide members are subjected to an upward force, which can cause the guide members to shrink, and can prevent the guide members from colliding with the circular rod below due to the upward movement of the disc two, thereby ensuring that the fire extinguishing bombs above can smoothly pass through the guide members and fall into the delivery holes below.

[0014] Preferably, the outer surfaces of the plurality of insertion rods are movably sleeved with a compression spring 1, one ends of the plurality of compression springs 1 are symmetrically fixedly installed in pairs on the opposite sides of the two fixing bars, and the other ends of the plurality of compression springs 1 are symmetrically fixedly installed in pairs on the opposite sides of the two connecting bars. Under the restoring force of the compression spring 1, the insertion rod can be inserted into the interior of the limiting hole to achieve the limitation of the convex slider.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:

[0016] 1. According to the present invention, when the fire extinguishing bomb is gradually dropped into the forest fire site, the overall mass of the drone body becomes lighter. At this time, the pressure of the weight of the fire extinguishing bomb on the disc 2 gradually decreases, so that the disc 2 gradually moves toward the disc 1 under the restoring force of the compression spring 2, and the movable rod 1 slides upward along the disc 1 simultaneously, so that the distance between the disc 1 and the disc 2 gradually decreases, thereby reducing the volume of the fire extinguishing bomb carrier. In this way, the wind resistance on the fire extinguishing bomb carrier is smaller, thereby avoiding the shaking of the drone body, thereby improving the flight safety of the drone body.

[0017] 2. The present invention controls the motor to start through a controller so that its output shaft drives the hollow rotating rod to rotate, and then with the cooperation of the guide bar and the guide groove, the solid rotating rod can rotate synchronously with the hollow rotating rod, and the solid rotating rod can slide up and down along the inside of the circular ring, thereby driving the circular ring, the circular rod and the triangular block 1 to rotate around the central axis of the hollow rotating rod, so that the ball contacts and squeezes the inclined surface of the triangular block 2, thereby driving the baffle plate to move upward, compressing the compression spring 3, and making the fire extinguishing bomb slide downward along the groove of the fire extinguishing bomb placement frame under the action of gravity, so that the fire extinguishing bomb is released toward the forest fire below through the release hole, and this is repeated, so that the high-efficiency release of the fire extinguishing bomb can be achieved, thereby improving the effect of forest fire extinguishing.

[0018] 3. In the present invention, when the shielding plate moves upward, it can simultaneously drive the support rod and the ring to move upward, so that the guide member is subjected to an upward force, which can cause the guide member to shrink, thereby preventing the guide member from colliding with the lower round rod due to the upward movement of the second disk, thereby ensuring that the upper fire extinguishing bomb can smoothly pass through the guide member and fall into the lower delivery hole, which can not only ensure the smooth delivery of the upper fire extinguishing bomb, but also ensure that the volume of the fire extinguishing bomb carrier becomes smaller.

[0019] 4. In the present invention, when the fire extinguishing bomb carrier needs to be separated from the drone body, the handle is held by hand and pulled outward, so that the insertion rod can be disengaged from the inside of the limiting hole, the limiting of the convex slider is released, and the compression spring is stretched synchronously. At this time, the convex slider can be slid to one side along the convex slide groove, so that the fire extinguishing bomb carrier can be separated from the drone body, so that the drone body can be quickly installed and combined with another group of fire extinguishing bomb carriers, thereby improving the overall efficiency of forest fire fighting.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1, as Figure 1-9 As shown, the present invention provides a technical solution: a fire-fighting drone, comprising: a drone body 1, two fixing bars 2 are symmetrically fixedly installed at the bottom of the drone body 1, convex slide grooves 206 are provided at the bottom of the two fixing bars 2, convex sliders 201 are movably embedded in the interior of the two convex slide grooves 206, connecting rods 3 are fixedly installed on the opposite sides of the two convex sliders 201 near the bottom, a disk 301 is fixedly installed at one end of the multiple connecting rods 3, two movable rods 302 are symmetrically and movably embedded at the top of the disk 301, and a circular rod 302 is fixedly installed at one end of the two movable rods 302. Disk 1 304 and the outer surfaces of the two movable rods 1 302 are movably sleeved with compression springs 2 303, the tops of disk 1 301 and disk 2 304 are fixedly installed with multiple fire bomb placement frames 305 in a circular array, the tops of disk 1 301 and disk 2 304 are opened with multiple delivery holes 307 in a circular array near the center of the circle, one end of the two compression springs 2 303 is symmetrically fixedly installed on the bottom of disk 1 301, the other ends of the two compression springs 2 303 are symmetrically fixedly installed on the top of disk 2 304, and the other ends of the two movable rods 1 302 are fixedly sleeved with limit rings 306.

[0033] In this embodiment, when the fire extinguishing bombs are gradually dropped into the forest fire site, the overall mass of the drone body 1 becomes lighter. At this time, the pressure exerted by the weight of the fire extinguishing bomb on the disc 2 304 gradually decreases, so that the disc 2 304 gradually moves toward the disc 1 301 under the restoring force of the compression spring 2 303, and the movable rod 1 302 slides upward along the disc 1 301 simultaneously, so that the distance between the disc 1 301 and the disc 2 304 gradually decreases, thereby reducing the volume of the fire extinguishing bomb carrier. In this way, the wind resistance on the fire extinguishing bomb carrier is smaller, thereby avoiding the shaking of the drone body 1, thereby improving the flight safety of the drone body 1.

[0034] Embodiment 2, as Figure 1-9 As shown, the bottom of the inner wall of the plurality of fire extinguishing bomb placement frames 305 is arranged to be inclined downward, a fixed block 501 is fixedly installed on the opposite side near one end of the plurality of fire extinguishing bomb placement frames 305, a movable rod 2 502 is movably embedded in the center of the plurality of fixed blocks 501, the plurality of movable rods 2 502 are evenly divided into a group of two, a shielding plate 5 is fixedly installed on one end of the plurality of groups of movable rods 2 502, a compression spring 3 503 is movably sleeved on the outer surface of the plurality of movable rods 2 502, one end of the plurality of compression springs 3 503 is respectively fixedly installed on the bottom of the plurality of fixed blocks 501, and the other end of the plurality of compression springs 3 503 is respectively fixedly installed on the other end of the plurality of movable rods 2 502, a fixed plate 4 is fixedly installed on the opposite side near the bottom of the two convex sliding blocks 201, a motor 401 is fixedly installed at the center of the bottom of the fixed plate 4, a hollow rotating rod 402 is movably embedded in the center of the disc 1 301, a solid rotating rod 404 is movably embedded in the center of the disc 2 304, and the outer surface of the solid rotating rod 404 The outer surface of the two guide bars 408 is movably embedded in the interior of the hollow rotating rod 402, the output end of the motor 401 is fixedly installed at one end of the hollow rotating rod 402, the inner wall of the hollow rotating rod 402 is symmetrically fixedly installed with two guide bars 408, the outer surface of the solid rotating rod 404 is symmetrically provided with two guide grooves 409, the outer surfaces of the two guide bars 408 are movably embedded in the interior of the two guide grooves 409, and the outer surface of the hollow rotating rod 402 near the top and the outer surface of the solid rotating rod 404 near the bottom are fixedly sleeved with a ring 4 03, two round rods 405 are symmetrically fixedly installed on the outer surfaces of the two circular rings 403, a triangular block 406 is fixedly installed at one end of the multiple round rods 405, a plurality of balls 407 are movably embedded in the inclined surfaces of the multiple triangular blocks 406, a triangular block 504 is fixedly installed at the bottom of the multiple shielding plates 5, and a plurality of anti-deviation parts 308 are arranged in a circular array on the top of the disk 1 301 and the disk 2 304, and the plurality of anti-deviation parts 308 respectively correspond to the plurality of delivery holes 307.

[0035] In one embodiment, the anti-deviation member 308 is fixedly installed on the top of the disc 1 301 and the disc 2 304. The anti-deviation member 308 is in the shape of an arc plate with a certain inclination. By placing the fire extinguishing bomb in the groove of the fire extinguishing bomb placement frame 305, multiple fire extinguishing bombs can be placed in the groove of each fire extinguishing bomb placement frame 305. Since the groove of the fire extinguishing bomb placement frame 305 is set to be inclined downward, the fire extinguishing bomb has a tendency to roll downward, but due to the existence of the shielding plate 5, the fire extinguishing bomb cannot roll downward. Then, the drone body 1 is controlled to take off to transport the fire extinguishing bomb to the forest fire scene. When the motor 401 is started, the controller is used to control the motor 401 to start, so that its output shaft drives the hollow rotating rod 402 to rotate, and then, with the cooperation of the guide bar 408 and the guide groove 409, the solid rotating rod 404 can follow the hollow rotating rod 402 to rotate synchronously, and the solid rotating rod 404 can slide up and down along the inside of the ring 403, so as to drive the ring 403, the round rod 405 and the triangle block 1 406 to rotate around the central axis of the hollow rotating rod 402, so that the ball 407 contacts the inclined surface of the triangle block 2 504 and squeezes it. By setting the ball 407, the friction of the triangle block 2 504 can be reduced. The angle block 1 406 and the triangle block 2 504 are both set in a triangular shape, so that the triangle block 2 504 is subjected to an upward force, thereby driving the shielding plate 5 to move upward, and synchronously moving the movable rod 2 502 upward, so that the compression spring 3 503 is compressed. At this time, the fire extinguishing bombs in the grooves of the multiple fire extinguishing bomb placement frames 305 are freed from the obstruction, so that the fire extinguishing bombs slide downward along the grooves of the fire extinguishing bomb placement frame 305 under the action of gravity, so that the fire extinguishing bombs are released toward the forest fire below through the delivery hole 307, and with the cooperation of the anti-deviation member 308, the fire extinguishing bombs can be prevented from deviating. The blocks 1 406 are symmetrically arranged in pairs, so that after the fire extinguishing bomb is released, the drone body 1 will not shake due to the sudden change in the overall mass. When the triangular block 1 406 rotates a certain angle, the contact between the ball 407 and the triangular block 2 504 is released. At this time, the squeezing force on the triangular block 2 504 disappears. Under the reset force of the compression spring 3 503, the triangular block 2 504 can be moved downward and returned to its original position, thereby re-blocking the fire extinguishing bomb in the slot of the fire extinguishing bomb placement frame 305. This process is repeated to achieve high-efficiency release of the fire extinguishing bomb, thereby improving the effect of forest fire extinguishing.

[0036] In another embodiment, the anti-deviation member 308 is fixedly installed on the top of the disc 1 301 and the disc 2 304. The anti-deviation member 308 is U-shaped. By placing the fire extinguishing bomb in the groove of the fire extinguishing bomb placement frame 305, multiple fire extinguishing bombs can be placed in the groove of each fire extinguishing bomb placement frame 305. Since the groove of the fire extinguishing bomb placement frame 305 is set to be inclined downward, the fire extinguishing bomb has a tendency to roll downward, but due to the existence of the shielding plate 5, the fire extinguishing bomb cannot roll downward. Then, the drone body 1 is controlled to take off so that it transports the fire extinguishing bomb to the forest fire scene. At this time, the controller controls the electric The machine 401 is started, and its output shaft drives the hollow rotating rod 402 to rotate. Then, with the cooperation of the guide bar 408 and the guide groove 409, the solid rotating rod 404 can follow the hollow rotating rod 402 to rotate synchronously, and the solid rotating rod 404 can slide up and down along the inside of the ring 403, thereby driving the ring 403, the round rod 405 and the triangular block 1 406 to rotate around the central axis of the hollow rotating rod 402, so that the ball 407 contacts the inclined surface of the triangular block 2 504 and squeezes it. The setting of the ball 407 can reduce the friction of the triangular block 2 504. 6 and the triangular block 2 504 are both set in a triangular shape, so that the triangular block 2 504 is subjected to an upward force, thereby driving the shielding plate 5 to move upward, and synchronously moving the movable rod 2 502 upward, so that the compression spring 3 503 is compressed. At this time, the fire extinguishing bombs in the grooves of the multiple fire extinguishing bomb placement frames 305 are freed from the obstruction, so that the fire extinguishing bombs slide downward along the grooves of the fire extinguishing bomb placement frame 305 under the action of gravity, so that the fire extinguishing bombs are released toward the forest fire below through the delivery hole 307, and with the cooperation of the anti-deviation member 308, the fire extinguishing bombs can be prevented from deviating. 06 is symmetrically arranged in pairs, so that after the fire extinguishing bomb is released, the drone body 1 will not shake due to the sudden change of the overall mass. When the triangle block 1 406 rotates a certain angle, the contact between the ball 407 and the triangle block 2 504 is released. At this time, the squeezing force on the triangle block 2 504 disappears. Under the reset force of the compression spring 3 503, the triangle block 2 504 can be moved downward and returned to its original position, so as to block the fire extinguishing bomb in the slot of the fire extinguishing bomb placement frame 305 again. This can be repeated to achieve high-efficiency release of the fire extinguishing bomb, thereby improving the effect of forest fire extinguishing.

[0037] Embodiment 3, as Figure 1-9 As shown, a plurality of guide members 6 are arranged in a circular array at the bottom of the disk 301, and a ring 601 is fixedly sleeved on the outer surface of the plurality of guide members 6 near the bottom, and a support rod 602 is fixedly installed on the outer surface of the plurality of rings 601, and one end of the plurality of support rods 602 is respectively fixedly installed on one side of a plurality of baffle plates 5 near the bottom.

[0038] In one embodiment, the guide member 6 is fixedly installed at the bottom of the disc 1 301. The guide member 6 uses a telescopic conical cylinder. When the baffle plate 5 moves upward, it can simultaneously drive the support rod 602 and the ring 601 to move upward, so that the guide member 6 is subjected to an upward force, which can cause the guide member 6 to shrink. This can prevent the guide member 6 from colliding with the circular rod 405 below due to the upward movement of the disc 2 304, and ensure that the fire extinguishing bomb above can smoothly pass through the guide member 6 and fall into the delivery hole 307 below. This not only ensures the smooth delivery of the fire extinguishing bomb above, but also ensures that the volume of the fire extinguishing bomb carrier is reduced.

[0039] In another embodiment, the guide member 6 is fixedly installed at the bottom of the disc 1 301. The guide member 6 uses a telescopic hose. When the baffle plate 5 moves upward, it can simultaneously drive the support rod 602 and the ring 601 to move upward, so that the guide member 6 is subjected to an upward force, which can cause the guide member 6 to shrink. This can prevent the guide member 6 from colliding with the circular rod 405 below due to the upward movement of the disc 2 304, and ensure that the fire extinguishing bomb above can smoothly pass through the guide member 6 and fall into the delivery hole 307 below. This not only ensures the smooth delivery of the fire extinguishing bomb above, but also ensures that the volume of the fire extinguishing bomb carrier is reduced.

[0040] Embodiment 4, as Figure 1-9 As shown, two insertion rods 202 are symmetrically and movably embedded on the opposite sides of the two fixed bars 2, and the multiple insertion rods 202 are evenly divided into two groups. One end of the two groups of insertion rods 202 is fixedly installed with a connecting bar 203, and one side of the two connecting bars 203 is fixedly installed with a handle 204. Two convex sliding blocks 201 have two limiting holes 207 symmetrically opened on one side near the top, and one end of the multiple insertion rods 202 is movably embedded in the inside of the multiple limiting holes 207, and the outer surfaces of the multiple insertion rods 202 are movably sleeved with compression springs 205, and one ends of the multiple compression springs 205 are symmetrically fixedly installed on the opposite sides of the two fixed bars 2 in pairs, and the other ends of the multiple compression springs 205 are symmetrically fixedly installed on the opposite sides of the two connecting bars 203 in pairs.

[0041] In this embodiment, when the fire extinguishing bomb carrier needs to be separated from the drone body 1, by holding the handle 204 with hand and pulling it outward, the insertion rod 202 can be disengaged from the inside of the limiting hole 207, releasing the limit on the convex slider 201, and simultaneously stretching the compression spring 205. At this time, the convex slider 201 can be slid to one side along the convex slide groove 206, so that the fire extinguishing bomb carrier can be separated from the drone body 1, so that the drone body 1 can be quickly installed and combined with another group of fire extinguishing bomb carriers, thereby improving the overall efficiency of forest fire fighting.

[0042] Working principle: When in use, first place the fire extinguishing bomb in the groove of the fire extinguishing bomb placement frame 305. Multiple fire extinguishing bombs can be placed in the groove of each fire extinguishing bomb placement frame 305. Since the groove of the fire extinguishing bomb placement frame 305 is set to be inclined downward, the fire extinguishing bomb has a tendency to roll downward, but due to the presence of the baffle plate 5, the fire extinguishing bomb cannot roll downward. Then, the drone body 1 is controlled to take off so that it can transport the fire extinguishing bomb to the forest fire scene. At this time, the controller controls the motor 401 to start so that its output shaft drives the hollow rotating rod 402 to rotate. Then, with the cooperation of the guide bar 408 and the guide groove 409, the solid rotating rod 404 can rotate synchronously with the hollow rotating rod 402, and the solid rotating rod 404 can rotate along the ring 403. The inner part slides up and down, thereby driving the circular ring 403, the round rod 405 and the triangular block 1 406 to rotate around the central axis of the hollow rotating rod 402, so that the ball 407 contacts the inclined surface of the triangular block 2 504 and squeezes it. The setting of the ball 407 can reduce the friction of the triangular block 2 504. Since the triangular block 1 406 and the triangular block 2 504 are both set in a triangular shape, the triangular block 2 504 is subjected to an upward force, thereby driving the shielding plate 5 to move upward, and synchronously moving the movable rod 2 502 upward to compress the compression spring 3 503. At this time, the fire extinguishing bombs in the grooves of the multiple fire extinguishing bomb placement frames 305 are freed from the obstruction, so that the fire extinguishing bombs move along the fire extinguishing bomb placement frames under the action of gravity. The first triangular block 406 is symmetrically arranged in pairs, so that after the fire extinguishing bomb is dropped, the drone body 1 will not shake due to the sudden change of the overall mass. When the first triangular block 406 rotates a certain angle, the contact between the ball 407 and the second triangular block 504 is released. At this time, the squeezing force on the second triangular block 504 disappears. Under the reset force of the compression spring three 503, the second triangular block 504 can be moved downward and returned to its original position, so as to block the fire extinguishing bomb in the slot of the fire extinguishing bomb placement frame 305 again. This can be repeated. In order to achieve high-efficiency delivery of fire extinguishing bombs, thereby improving the effect of forest fire extinguishing, when the fire extinguishing bombs are gradually delivered to the forest fire site, the overall mass of the drone body 1 becomes lighter, and the pressure of the weight of the fire extinguishing bomb on the disc 2 304 gradually decreases, so that the disc 2 304 gradually moves toward the disc 1 301 under the reset force of the compression spring 2 303, and the movable rod 1 302 slides upward along the disc 1 301, so that the distance between the disc 1 301 and the disc 2 304 gradually decreases, thereby reducing the volume of the fire extinguishing bomb carrier, so that the wind resistance of the fire extinguishing bomb carrier is small, thereby avoiding the shaking of the drone body 1, thereby improving the flight safety of the drone body 1, and when the shielding plate 5 moves upward,The support rod 602 and the collar 601 can be driven to move upward synchronously, so that the guide member 6 is subjected to an upward force, which can cause the guide member 6 to shrink, and can prevent the guide member 6 from colliding with the lower round rod 405 due to the upward movement of the disc 2 304, so as to ensure that the upper fire extinguishing bomb can smoothly pass through the guide member 6 and fall into the lower delivery hole 307. In this way, not only can the smooth delivery of the upper fire extinguishing bomb be ensured, but also the volume of the fire extinguishing bomb carrier can be reduced. When the fire extinguishing bomb carrier needs to be separated from the drone body 1, the handle 204 can be held by hand and pulled outward to make the insert The rod 202 is disengaged from the inside of the limiting hole 207, releasing the limiting of the convex slider 201, and synchronously stretching the compression spring 1 205. At this time, the convex slider 201 can slide to one side along the convex slide groove 206, so that the fire extinguishing bomb carrier can be separated from the drone body 1, so that the drone body 1 can be quickly installed and combined with another set of fire extinguishing bomb carriers. The first round uses chemical fire extinguishing bombs, the second round uses foam covering fire extinguishing bombs, and the third round uses fire-based spray cooling fire extinguishers. The forest fire is extinguished by a combination of multiple rounds, thereby improving the overall efficiency of forest fire extinguishing.
