Description
Technical Field
[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically, it relates to a mounting structure for a forest fire inspection UAV. Background Technology
[0002] As forest resources play an increasingly important role in the ecological environment, the effective protection and supervision of forests has become a key task. Forest fire inspection drones, as an important tool in modern forest protection work, can quickly traverse forest areas and monitor fire hazards in real time, greatly improving inspection efficiency.
[0003] Its mounting structure is an important component that carries key rescue or emergency response supplies such as fire extinguishing bombs and first aid kits. The mounting structure connects various supplies to the main body of the drone, enabling it to be deployed when needed to assist in responding to emergencies such as forest fires.
[0004] However, when the fire extinguishing bombs or first aid kits are deployed, the drone's center of gravity will suddenly shift due to the instantaneous loss of this weight. After deployment, the drone will have difficulty adapting to the weight change, which will easily cause it to sway. The swaying amplitude may gradually increase, and in severe cases, it may even cause the drone to go out of control. An out-of-control drone will not only be unable to continue to complete the inspection mission, but it is also very likely to crash in the forest, causing equipment damage, increasing maintenance costs, and may also cause other safety hazards in the forest, such as hitting trees or causing secondary disasters such as small-scale fires.
[0005] To address the aforementioned issues, this application proposes a mounting structure for a forest fire inspection drone. Utility Model Content

[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A mounting structure for a forest fire inspection drone includes a drone body, an adjustment structure on the outer side wall of the drone body, and a limit structure on the adjustment structure.
[0009] The adjustment structure includes a crossbar fixedly connected to the outer wall of the drone body. A base plate is fixedly connected to the outer wall of the support frame of the drone body. A delivery hatch is provided on the base plate. A connecting seat is provided at the top of the delivery hatch. A sliding rod is fixedly connected to the inner wall of the crossbar. A slider is slidably connected to the outer wall of the sliding rod. A cable is fixedly connected to the outer wall of the connecting seat. The end of the cable away from the connecting seat is fixedly connected to the outer wall of the slider. A counterweight is threadedly connected to the bottom of the slider. A threaded hole is provided at the bottom of the counterweight. A return spring is fixedly connected to the outer wall of the slider. The return spring is located outside the sliding rod.
[0010] Preferably, a mounting box is fixedly connected to the bottom of the base plate, and a mounting hole is provided on the top of the base plate. A motor is fixedly connected to the base plate through the mounting hole. A connecting wheel is fixedly connected to the outside of the output shaft of the motor. A connecting rope is fixedly connected to the outer side wall of the connecting wheel. A locking block is fixedly connected to the end of the connecting rope away from the motor. A limit rod is fixedly connected to the inner side wall of the mounting box. The locking block is slidably connected to the limit rod. By setting up the motor, connecting wheel, connecting rope, and locking block, it is convenient to release and engage the release hatch to facilitate the release of fire extinguishing bombs or emergency medical kits.
[0011] Preferably, an anti-wear roller is fixedly connected to the outer wall of the crossbar, and the outer wall of the anti-wear roller is in contact with the outer wall of the cable to reduce the wear of the cable. By setting the anti-wear roller, excessive friction between the cable and the crossbar is avoided, which could lead to cable breakage.
[0012] Preferably, a roller is rotatably connected to the outer wall of the slider, and the roller is in contact with the inner wall of the crossbar to reduce the friction between the slider and the inner wall of the crossbar. By setting the roller, the slider is prevented from getting stuck during its movement inside the crossbar.
[0013] Preferably, a stop bar is fixedly connected to the inner bottom of the mounting box, and the outer side wall of the stop bar is in contact with the outer side wall of the connecting rope to facilitate changing the angle of the connecting rope. A spring is fixedly connected to the outer side wall of the end of the locking block near the motor, and the end of the spring away from the locking block is fixedly connected to the inner side wall of the mounting box. By setting the stop bar and the spring, it is easy to pull and reset the locking block, thereby facilitating the locking of the deployment hatch.
[0014] Preferably, the limiting structure includes a mesh fixedly connected to the top of the delivery hatch, a sliding groove on the top of the delivery hatch, a fixed plate fixedly connected to the bottom of the delivery hatch, a round rod fixedly connected to the outer wall of the fixed plate, a moving block slidably connected to the outer wall of the round rod, a connecting block fixedly connected to the top of the moving block, and an arc-shaped plate rotatably connected to the top of the connecting block. By setting the moving block, the connecting block, and the arc-shaped plate, the fire extinguishing bomb or medical kit can be limited, and during delivery, the arc-shaped plate can be flipped by the weight of the two items to release the lock.
[0015] Preferably, a lever is fixedly connected to the bottom of the movable block, and a compression spring is provided on the outer wall of the round rod. One end of the compression spring is fixedly connected to the outer wall of the fixed plate, and the end of the compression spring away from the fixed plate is fixedly connected to the outer wall of the movable block. By providing the lever and the compression spring, it is convenient for operators to install and fix the fire extinguishing bomb and the medical kit.
[0016] In summary, the technical effects and advantages of this utility model are as follows: The mounting structure of this forest fire inspection drone, through the coordinated use of a crossbar, base plate, deployment hatch, connecting seat, cable, sliding rod, slider, counterweight, and return spring, facilitates the adjustment of the slider's position by the rotating deployment hatch during deployment. This ensures that the drone maintains a stable flight attitude after deployment, avoiding swaying or loss of control due to center of gravity shift, reducing energy consumption during flight, extending the drone's endurance, and expanding the inspection range.
[0017] The combination of a chute, a fixed plate, a round rod, a moving block, a connecting block, an arc plate, and a compression spring facilitates the limiting of fire extinguishing bombs or first aid kits. When the release hatch rotates to release the bombs, the weight of the two components flips the arc plate, preventing them from shaking during inspection. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Reference Figure 1-4 A mounting structure for a forest fire inspection drone includes a drone body 1, an adjustment structure 2 on the outer side wall of the drone body 1, and a limit structure 3 on the adjustment structure 2.
[0030] The adjustment structure 2 includes two crossbars 201 fixedly connected to the outer wall of the UAV body 1. The two crossbars 201 are located on opposite sides of the UAV body 1 and are symmetrically distributed about the UAV body 1. A base plate 202 is fixedly connected to the outer wall of the support frame of the UAV body 1. The base plate 202 is located between the support frames of the UAV body 1. Two deployment doors 203 are provided on the base plate 202. The two deployment doors 203 are perpendicular to the two crossbars 201. Taking one deployment door 203 as an example, two connecting seats 204 are provided at the top of the deployment door 203. A sliding rod 2 is fixedly connected to the inner wall of one side of the two crossbars 201. 06. A slider 207 is slidably connected to the outer wall of the sliding rod 206. There are two sliders 207. A cable 205 is fixedly connected to the outer wall of the two connecting seats 204. The ends of the two cables 205 away from the two connecting seats 204 are fixedly connected to the outer wall of the two sliders 207 respectively. A counterweight 208 is threadedly connected to the bottom of each slider 207. A threaded hole is opened at the bottom of each counterweight 208. The operator can increase the number of counterweights 208 according to the weight carried by the drone body 1, so as to adapt the weight on both sides of the drone body 1 during deployment. A return spring 209 is fixedly connected to the outer wall of each slider 207. The two return springs 209 are located outside the two sliding rods 206 respectively.
[0031] In use, the drone body 1 carries fire extinguishing bombs and an emergency medical kit to patrol the forest. When a fire is discovered, the fire extinguishing bombs are dropped to extinguish it. At this time, one of the release doors 203 rotates and opens downwards towards the drone body 1, allowing the fire extinguishing bombs above it to fall and extinguish the fire. As the release door 203 rotates, it moves one end of the cable 205 via the connecting seat 204. Since the end of the cable 205 away from the connecting seat 204 is fixedly connected to the slider 207, and the bottom of the slider 207 is equipped with a counterweight 208, when the release door 203 rotates downwards, it pulls the slider 207 and the counterweight 208 from the middle of the crossbar 201 towards the crossbar 202. One end of the drone body 1 moves, and the slider 207 and the counterweight 208 move towards the end that has been deployed. The weight of the deployment hatch 203 can overcome the elastic force of the return spring 209. Thus, the slider 207 compresses the return spring 209 during the movement. When it is necessary to deploy fire extinguishing bombs and medical first aid kits, the devices located on both sides below the drone body 1 will adjust the positions of the two sliders 207 and the counterweight 208 respectively, so as to adjust the center of gravity of the drone body 1 and prevent the center of gravity of the drone body 1 from changing during the inspection and rescue process. This will prevent the flight attitude of the drone body 1 from changing and avoid shaking or loss of control due to the shift of the center of gravity.
[0032] Reference Figure 4 A mounting box 212 is fixedly connected to the bottom of the base plate 202. The mounting box 212 is located at the center of the bottom of the base plate 202. Two mounting holes 213 are provided on the top of the base plate 202. Motors 214 are fixedly connected to the base plate 202 through the two mounting holes 213. Connecting wheels 215 are fixedly connected to the outer sides of the output shafts of both motors 214. Connecting ropes 216 are fixedly connected to the outer walls of the two connecting wheels 215. A locking block 219 is fixedly connected to the end of each connecting rope 216 away from the two motors 214. The two locking blocks 219 are located at both ends of the mounting box 212, and their positions are respectively aligned with... The two delivery hatches 203 are positioned correspondingly, and the portions of the two locking blocks 219 located outside the mounting box 212 are curved. The inner wall of the mounting box 212 is fixedly connected to a limit rod 218, and the locking blocks 219 are slidably connected to the limit rod 218. When delivery is required, the control motor 214 is started, which drives the connecting wheel 215 to rotate. When the connecting wheel 215 rotates, it will wind up the connecting rope 216. Since the connecting rope 216 is fixedly connected to one side of the locking block 219, when the connecting wheel 215 winds up the connecting rope 216, it will pull the locking block 219 toward the interior of the mounting box 212 adjustment structure 2, thereby releasing the locking block 219 from limiting the delivery hatch 203, so that the delivery hatch 203 can rotate for delivery.
[0033] Reference Figure 3 and Figure 4 The outer wall of the crossbar 201 is fixedly connected with anti-wear rollers 211. Four anti-wear rollers 211 are provided. The four anti-wear rollers 211 are located at both ends of the two crossbars 201 respectively. The outer walls of the four anti-wear rollers 211 are respectively in contact with the outer walls of the four cables 205 to reduce the wear between the four cables 205 and the two crossbars 201 and to prevent the four cables 205 from breaking during use.
[0034] Reference Figure 4 Rollers 210 are rotatably connected to the outer wall of slider 207. There are four rollers 210, which correspond to the positions of the four sliders 207 respectively. The four rollers 210 are in contact with the inner walls of the two crossbars 201 respectively, so as to reduce the friction between the sliders 207 and the inner walls of the crossbars 201 and avoid jamming between the four sliders 207 and the inner walls of the two crossbars 201 during the movement of the two sliders 207.
[0035] Reference Figure 4The bottom inner wall of the mounting box 212 is fixedly connected to a stop bar 217. Two stop bars 217 are provided, with their outer walls respectively fitting against the outer walls of the two connecting ropes 216 to adjust the angle of the ropes 216. This allows the ends of the ropes 216 connected to the two locking blocks 219 to be perpendicular to the blocks. Springs 220 are fixedly connected to the outer walls of the two locking blocks 219 near the two motors 214. The ends of the springs 220 away from the locking blocks 219 are fixedly connected to the inner walls of the two mounting boxes 212. After deployment, the UAV body 1 flies back to the resupply base, and the operator can... The fire extinguishing bombs and medical kits are replenished. When the delivery hatch 203 is rotated to close, because one end of the return spring 209 is curved, when the delivery hatch 203 rotates, the end of the delivery hatch 203 near the locking block 219 fits against the outer wall of the locking block 219 and squeezes the locking block 219, causing the locking block 219 to move into the mounting box 212 and compress the spring 220. When the delivery hatch 203 returns to its original position, the locking block 219 pops out to the outside of the mounting box 212 under the elastic force of the spring 220, so as to lock the delivery hatch 203 and prevent the delivery hatch 203 from rotating and opening downwards towards the main body of the UAV 1.
[0036] Reference Figure 1 , Figure 2 and Figure 6 The limiting structure 3 includes a mesh 301 fixedly connected to the top of the delivery hatch 203. The outer wall of the mesh 301 has holes to reduce wind resistance of the UAV body 1. The top of the delivery hatch 203 has four sliding grooves 302, each located at the top of one of the two delivery hatches 203. Taking one of the delivery hatches 203 as an example, the bottom of this delivery hatch 203 is fixedly connected to four fixing plates 303. A round rod 304 is fixedly connected between the outer walls of two fixing plates 303. A movable block 305 is slidably connected to the outer wall of the device. A connecting block 306 is fixedly connected to the top of the movable block 305. An arc-shaped plate 307 is rotatably connected to the top of the connecting block 306. The arc-shaped plate 307 is arc-shaped, so that when the release hatch 203 rotates to release the fire extinguishing bomb, the center of gravity of the fire extinguishing bomb changes. As a result, the fire extinguishing bomb can use its own weight to press the end of the arc-shaped plate 307 away from the connecting block 306. Under the pressure of the weight of the fire extinguishing bomb, the arc-shaped plate 307 rotates along the connection point with the connecting block 306, releasing the restriction on the fire extinguishing bomb.
[0037] Reference Figure 6A lever 308 is fixedly connected to the bottom of the movable block 305. The lever 308 allows the operator to quickly adjust the position of the arc plate 307 when replenishing materials. A compression spring 309 is provided on the outer wall of the round rod 304. One end of the compression spring 309 is fixedly connected to the outer wall of the fixed plate 303, and the end of the compression spring 309 away from the fixed plate 303 is fixedly connected to the outer wall of the movable block 305. When replenishing materials, the elastic force of the compression spring 309 can be used to compress the movable block 305 so that the outer wall of the arc plate 307 fits against the outer wall of the material.
[0038] Working principle: During use, the drone body 1 carries fire extinguishing bombs and an emergency medical kit to patrol the forest. When a fire is discovered, the fire extinguishing bombs are dropped to extinguish the fire. At this time, one of the release doors 203 rotates and opens downwards towards the drone body 1, allowing the fire extinguishing bombs above it to fall and extinguish the fire. When the release door 203 rotates, it drives one end of the cable 205 to move through the connecting seat 204. Since the end of the cable 205 away from the connecting seat 204 is fixedly connected to the slider 207, and the bottom of the slider 207 is equipped with a counterweight 208, when the release door 203 rotates downwards, it will pull the slider 207 and the counterweight 208 from the middle of the crossbar 201 towards the horizontal. One end of lever 201 moves, and the slider 207 and counterweight 208 move towards the end that has been deployed. The weight of the deployment hatch 203 can overcome the elastic force of the return spring 209, so the slider 207 compresses the return spring 209 during the movement. When it is necessary to deploy fire extinguishing bombs and medical first aid kits, the devices located on both sides below the drone body 1 will adjust the positions of the two sliders 207 and counterweight 208 respectively, so as to adjust the center of gravity of the drone body 1, so as to avoid the drone body 1 from changing its center of gravity during the inspection and rescue process, thereby avoiding changes in the flight attitude of the drone body 1 and avoiding swaying or loss of control due to the shift of the center of gravity.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
