Description

Technical Field

[0002] In forest firefighting, drones are often equipped with fire extinguishing bombs. The drones are flown over the fire source, where they are then dropped, causing the bombs to explode and extinguish the fire. Drones have become an important firefighting method due to their flexibility and ability to quickly reach inaccessible areas. However, existing drone-based fire extinguishing bomb dropping systems have several drawbacks: The bombs are prone to shaking or even collisions during transportation and flight, which can damage or prematurely detonate the bombs, posing a safety hazard. Furthermore, when dropping a fire extinguishing bomb, the drone typically uses an electrically controlled latch to unlock the bomb, separating it from the drone. However, due to the bomb's heavy weight, the latch holds the entire weight, creating significant resistance when opening the latch, reducing the bomb's separation efficiency or delaying its release.

[0003] Based on this, a forest fire extinguishing bomb throwing device and a method of use are now provided to eliminate the drawbacks of the existing technical solutions. Summary of the Invention

[0017] The present invention also discloses a method for using a forest fire extinguishing bomb throwing device, and the specific steps of use are as follows:

[0018] S1. Open the door on one side of the cartridge case and place the fire extinguisher body inside the cartridge case, placing the lifting ring on the top of the fire extinguisher body inside the gear ring of the loading mechanism. At this time, the trapezoidal block supports the fire extinguisher body under the action of the spring force. The insertion rod is inserted into the slot of the slide to fix the slide in position.

[0019] S2. Secure the bomb carrier to the bottom of the drone with bolts. Operate the drone carrying the fire extinguisher bomb to fly over the target forest fire area. Adjust the drone's position so that the bomb is aimed above the fire source.

[0020] S3. At the target area, the operator controls the electric push rod to retract through the control device of the UAV body, driving the locking block to move out of the notch and the locking hole, thereby releasing the locking restriction on the gear ring;

The slide slides outward under the action of the spring force, and the trapezoidal block is separated synchronously to release the support for the fire extinguishing bomb body. The fire extinguishing bomb body falls from the cartridge to the fire source under the action of gravity, completing the throwing.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In the forest fire extinguishing bomb throwing device, the trapezoidal block forms a stable support for the bottom of the fire extinguishing bomb through the elastic force provided by the spring, and cooperates with the rubber pad on the surface to effectively buffer the vibration during transportation and flight, avoid the fire extinguishing bomb body from colliding with the inner wall of the cartridge and being damaged, and reduce the risk probability. The bomb loading mechanism limits the fire extinguishing bomb from the top through the cooperation of the gear ring and the lifting ring, and forms a coordinated fixation with the support mechanism to prevent the fire extinguishing bomb from being displaced when the flight posture of the UAV changes. The transmission mechanism links the bomb loading mechanism with the support mechanism. When the gear ring rotates to disengage the lifting ring from the notch, the insertion rod is synchronously driven to rise and disengage from the socket through the transmission of the active rod, transmission belt, bevel gear and other components. The support mechanism releases the support for the fire extinguishing bomb under the action of the spring, ensuring that the fire extinguishing bomb is smoothly thrown out in an unrestrained state, avoiding jamming or throwing delay.

DETAILED DESCRIPTION

[0032] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In this embodiment, if Figure 1 - Figure 7 As shown, a forest fire extinguishing bomb throwing device includes a bomb carrier 101 fixedly mounted on the bottom of the drone body, the top of the bomb carrier 101 can be mounted on the bottom of the drone body by a number of bolts to realize the throwing operation of the fire extinguishing bomb, the bomb carrier 101 can evenly distribute the weight of the fire extinguishing bomb body 102 on the drone body, ensuring the balance stability of the drone body when carrying the fire extinguishing bomb in flight, a number of cartridges 103 for placing the fire extinguishing bomb body 102 are fixedly mounted on the bomb carrier 101, the cartridges 103 can effectively prevent the collision and interference of external debris, branches, etc. on the fire extinguishing bomb body 102, and provide physical protection for the fire extinguishing bomb body 102 during the flight of the drone body, a lifting ring is fixedly provided on the top of the fire extinguishing bomb body 102, and the lifting ring is made of wear-resistant material, and a tripod 104 is fixedly mounted on the bottom of each cartridge 103 to enhance the stability of the device when placed on the ground, and a barrel door 105 is hinged on one side of the cartridge 103 to facilitate the operator to load and remove the fire extinguishing bomb body 102;

[0034] The bottom of the cartridge 103 is provided with a support mechanism 200 for supporting and protecting the fire extinguishing bomb body 102. The trapezoidal block 201 of the support mechanism 200 forms a flexible support for the fire extinguishing bomb body 102 from the bottom through the elastic force of the spring, and cooperates with the gear ring 307 of the bomb loading mechanism 300 to limit from the top to form an upper and lower fixation, thereby reducing the inertial force generated by the posture changes of the UAV body due to acceleration, deceleration, turning, etc. during flight, avoiding violent shaking or collision of the fire extinguishing bomb body 102 in the cartridge 103, and reducing the risk of accidental detonation due to friction and impact. A loading mechanism 300 is provided on the top for cooperating with the lifting ring to limit the position of the fire extinguishing bomb body 102. The loading mechanism 300 and the supporting mechanism 200 are connected by a transmission mechanism 400. The transmission mechanism 400 is used to synchronously release the supporting effect of the supporting mechanism 200 on the fire extinguishing bomb body 102 after the lifting ring is separated from the loading mechanism 300. The transmission mechanism 400 ensures that the lifting ring is separated from the loading mechanism 300 and the supporting mechanism 200 is released synchronously, so that the fire extinguishing bomb body 102 can fall by gravity without restraint, thereby reducing the trajectory deviation during the throwing process.

[0035] The supporting mechanism 200 includes a trapezoidal block 201 symmetrically arranged inside the cartridge 103. The trapezoidal block 201 can be adjusted to fit the shape of the fire extinguishing bomb body 102 according to actual needs. A slide plate 202 is fixedly connected to the opposite side of the two trapezoidal blocks 201. A fixed block 203 is symmetrically arranged on the outside of the cartridge 103. The cartridge 103 and the fixed block 203 are an integrated structure to improve the overall structural strength. One end of the slide plate 202 passes through the cartridge 103 and extends to the inside of the fixed block 203. A slide groove 204 is provided inside the fixed block 203. The slide plate 202 is slidably arranged inside the slide groove 204. The slide plate 202 is connected to the inner wall of the slide groove 204 by a spring. The spring can provide an elastic force toward one side of the fire extinguishing bomb body 102, so that the trapezoidal block 201 fits tightly against the fire extinguishing bomb body 1 02 bottom, when casting, after the insertion rod 206 is detached, the fire extinguishing bomb body 102 moves down and drives the slide plate 202 outward through elastic force, quickly releasing the support, and the upper surface of the slide plate 202 is provided with a socket 205, and the fixed block 203 is provided with a socket at a position corresponding to the socket 205, and a plug rod 206 is provided at the socket, one end of the plug rod 206 passes through the socket and is plugged into the inside of the socket 205, and the top of the plug rod 206 is connected to the transmission mechanism 400, thereby achieving the plugging effect of the socket 205. When the plug rod 206 is inserted into the socket 205, the position of the slide plate 202 is fixed by mechanical locking to ensure that the trapezoidal block 201 maintains a supported state during flight. The outer diameter of the socket 205 is larger than the outer diameter of the plug rod 206, which reduces the probability of difficulty in inserting the plug rod 206 or failure to pull out smoothly during casting;

[0036] Among them Figure 2 - Figure 7As shown, the ammunition loading mechanism 300 includes a cross bar 301 fixedly connected to the ammunition loading frame 101, the cross bar 301 is arranged above the ammunition cartridge 103, and a support frame 302 is fixedly installed on the cross bar 301. The support frame 302 provides wrapped protection for the gear 305 and the gear ring 307 to reduce the interference of airflow and dust on the transmission components during flight. The inner wall of the support frame 302 is provided with a gear groove 303 and a gear ring groove 304, the gear groove 303 and the gear ring groove 304 are connected, and a gear 305 is provided for rotation inside the gear groove 303. One end of the gear shaft of the gear 305 extends to the outside of the support frame 302, and the gear 305 is driven by a drive motor 306. The drive motor 306 is electrically connected to the control device of the drone body, and the drive motor 306 is fixedly installed on the support frame 302. The other end of the gear shaft of the gear 305 is connected to the transmission mechanism 400, so that when the gear ring is driven, the gear 305 is rotated. When the lifting ring 307 is released, the supporting mechanism 200 is synchronously driven to release the bottom support through the transmission mechanism 400. The bottom of the gear 305 is meshed with the gear ring 307. The gear ring 307 realizes radial limitation by fitting the inner ring surface with the lifting ring. The locking assembly can fix the initial position of the gear ring 307 to ensure that the lifting ring is always in a constrained state during flight. The driving motor 306 drives the gear ring 307 to rotate through the gear 305. When the notch 308 is rotated to the lifting ring position, the top constraint can be released to achieve directional release of the fire extinguishing bomb body 102. The gear ring 307 is rotatably arranged inside the gear ring groove 304. A notch 308 for removing the lifting ring is provided on one side of the gear ring groove 304. A locking assembly for limiting the notch 308 is provided on one side of the gear ring groove 304. The width of the notch 308 is larger than the width of the locking block 311, thereby reducing the probability that the lifting ring cannot be smoothly disengaged.

[0037] Among them Figure 5 and Figure 6 As shown, the locking assembly includes a vertical plate 309 fixedly mounted on the bottom of the support frame 302. An electric push rod 310 is installed on the side of the vertical plate 309 close to the gear ring 307. The output end of the electric push rod 310 is fixedly connected to a locking block 311. A locking hole 312 is provided on one side of the gear ring groove 304. One end of the locking block 311 passes through the locking hole 312 and is inserted into the inside of the notch 308. The locking block 311 can fix the initial position of the gear ring 307, ensuring that the inner ring surface of the gear ring 307 firmly constrains the lifting ring to prevent the lifting ring from detaching prematurely and causing safety hazards.

[0038] Among them Figure 4 and Figure 7As shown, the transmission mechanism 400 includes an active rod 401 fixedly connected to the gear shaft of the gear 305, a first transmission wheel is fixedly provided at the end of the active rod 401, a second transmission wheel is provided below the first transmission wheel, and the first transmission wheel and the second transmission wheel are connected by a transmission belt 402. The transmission belt 402 can be a synchronous belt or other belt type suitable for high-precision transmission. The specific type is selected according to the load and speed requirements and is suitable for the high-altitude operation environment of the UAV body. One end of the second transmission wheel is fixedly connected to the transmission rod 403, and the transmission rod 403 is rotatably connected to the outer wall of the cartridge 103. A first bevel gear 404 is fixedly installed on the transmission rod 403. The first bevel gear 404 One side of the second bevel gear 405 is meshed and connected, and the lower end of the second bevel gear 405 is fixedly connected to a threaded sleeve 406, and the internal thread of the threaded sleeve 406 is connected to the screw rod 407, and the threaded sleeve 406 is connected to the cartridge 103 through a bracket 408. The threaded sleeve 406 is rotatably connected to the bracket 408, and the bottom of the screw rod 407 is rotatably connected to the moving block 409. The bottom of the moving block 409 is fixedly connected to the top of the insertion rod 206. When the gear ring 307 rotates to release the lifting ring, the insertion rod 206 is synchronously disengaged from the socket 205 of the slide 202, so that the trapezoidal block 201 of the support mechanism 200 is separated under the action of the spring, realizing the synchronous linkage of top unlocking and bottom support release;

[0039] Among them Figure 1 As shown, a protective box 106 is provided on one side of the cartridge 103, and the protective box 106 wraps the transmission components such as the transmission belt 402 and the bevel gear to reduce the erosion of the components by external dust and water vapor, and at the same time avoid the interference of airflow on the transmission components during flight, thereby extending the service life of the device. An inspection door may be provided on one side of the protective box 106 to facilitate the later maintenance operations on the transmission components. The transmission belt 402, the transmission rod 403, the first bevel gear 404 and the second bevel gear 405 are all arranged inside the protective box 106. A control panel is provided on one side of the cartridge 103, and the control panel is electrically connected to the electrical components in the device and the control device in the drone body, so as to facilitate remote control of the drive motor 306 and the electric push rod 310, realize the rotation of the gear ring 307, the extension and retraction of the locking block 311 and other operations, which is convenient for the operator to use;

[0040] Among them Figure 4 and Figure 7 As shown, a movable groove 410 adapted to the movable block 409 is formed on the outer wall of the cartridge 103. The movable block 409 is slidably connected to the movable groove 410. The movable groove 410 serves as a guide to prevent the rod 206 from deflecting or getting stuck when the transmission mechanism 400 drives the rod 206 to rise or fall, so that the rod 206 can be accurately aligned with the socket 205 on the slide 202.

[0041] Among them Figure 5As shown, the cross-section of the trapezoidal block 201 is in the shape of a right-angled trapezoid, and the hypotenuse of the right-angled trapezoid is inclined toward the bottom of the fire extinguishing bomb body 102. The hypotenuse can guide the fire extinguishing bomb body 102 to automatically return to its original position during loading. A rubber pad is provided on the surface of the trapezoidal block 201. The rubber pad is made of high-temperature resistant and wear-resistant material. During the flight of the UAV body, when the fire extinguishing bomb body 102 shakes slightly due to changes in flight posture, the rubber pad can cushion the impact force between the fire extinguishing bomb body 102 and the trapezoidal block 201 through its own deformation, avoiding the severe friction caused by direct hard contact between the two, thereby reducing wear on the outer shell of the fire extinguishing bomb body 102 and ensuring its stability during transportation and flight.

[0042] When in use, first open the barrel door 105 on one side of the cartridge 103, put the fire extinguishing bomb body 102 into the cartridge 103, and place the lifting ring on the top of the fire extinguishing bomb body 102 on the inner side of the toothed ring 307 of the bomb loading mechanism 300. At this time, the trapezoidal block 201 supports the fire extinguishing bomb body 102 under the action of the spring force, and the plug rod 206 is inserted into the socket 205 of the slide plate 202 to fix the position of the slide plate 202. The electric push rod 310 is controlled to extend the output end so that the locking block 311 passes through the locking port 312 and is plugged into the toothed ring 307. 07, the fire extinguishing bomb body 102 is loaded and fixed inside the notch 308, the bomb carrier 101 is fixed to the bottom of the drone body by bolts, and the drone body is operated to carry the fire extinguishing bomb body 102 to the sky above the forest fire target area. The drone body adjusts its position so that the cartridge 103 is aimed above the fire source. At the target area, the operator controls the electric push rod 310 to retract through the control device of the drone body, driving the locking block 311 to move out of the notch 308 and the locking hole 312, releasing the lock. The locking limit of the gear ring 307 is then started, and the drive motor 306 is started to drive the gear 305 to rotate. The gear 305 engages and drives the gear ring 307 to rotate in the gear ring groove 304. When the notch 308 of the gear ring 307 rotates to the lifting ring position, the lifting ring is released from the notch 308 and the gear shaft of the gear 305 drives the first transmission wheel to rotate through the active rod 401, and the second transmission wheel and the transmission rod 403 are rotated through the transmission belt 402. The first bevel gear 404 engages and drives the second bevel gear 405 rotates, the threaded sleeve 406 rotates with the second bevel gear 405 and drives the screw 407 to rise, and then pulls the insertion rod 206 up and out of the socket 205 through the moving block 409, and the slide plate 202 slides outward under the action of the spring force, and the trapezoidal block 201 is synchronously separated to release the support for the fire extinguishing bomb body 102. The fire extinguishing bomb body 102 falls from the cartridge 103 to the fire source under the action of gravity, completing the casting. After casting, the drive motor 306 is controlled to reverse to reset the components for next use.
