Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) equipment technology, specifically to a dust monitoring device mounted on a UAV. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft that are autonomously controlled by radio remote control equipment or onboard computer programs. Their core system consists of five parts: the UAV platform carrying all components, the flight control system ensuring flight stability and navigation, the communication module responsible for data transmission, the ground control station for control and data reception, and the payload for specific tasks, such as cameras and sensors. The fuselage commonly uses lightweight materials such as carbon fiber and aluminum alloy, and the power sources are either electric or fuel-powered to adapt to different flight requirements. In the field of dust monitoring, UAVs, with their high mobility and wide coverage, have become an important supplement to traditional ground monitoring and are often used as "aerial eyes" to carry out dust control work.

[0003] Drone dust detection operations often require the use of equipment such as lidar and high-definition cameras. During the detection process, the load is often in a state of dynamic fluctuation. If the power monitoring is not accurate enough, it may misjudge the remaining power and cause an unexpected power outage due to insufficient actual power, resulting in the drone crashing. Summary of the Invention

A moving iron core that cooperates with the stationary iron core is slidably provided on the mounting housing. The moving iron core is fixedly connected to a corresponding connecting rod. A fixing plate is installed at the end of the moving iron core, and an elastic element is installed on the side of the fixing plate. The end of the elastic element is fixed to the mounting housing.

[0008] Preferably, a drive motor is fixedly installed inside the mounting box, and an adjusting plate is fixedly installed on the output shaft of the drive motor. The adjusting plate has multiple arc-shaped channels. An anti-deviation rod is installed at the top of the clamping and fixing rod. The anti-deviation rod is slidably disposed in a slide rail opened on the mounting box, and a sliding rod is fixedly installed at the top of the anti-deviation rod. The sliding rod is slidably disposed in the corresponding arc-shaped channel.

[0009] Preferably, the bottom of the landing box is provided with a locking mechanism, the locking mechanism including a locking box fixedly installed between the landing box and the drone body, gears being fixedly installed on the shafts of multiple propellers of the drone body, multiple drive rods being slidably provided on the locking box, and toothed plates cooperating with the gears being fixedly installed at the ends of the drive rods.

[0010] Preferably, a vent is provided at the connection between the locking box and the landing box, a movable plate is slidably installed inside the locking box, a wedge block one is fixedly installed at the bottom of the movable plate, and a wedge block two that cooperates with the wedge block one is fixedly installed at the end of the movable plate near the wedge block one.

[0011] Preferably, a trapezoidal slider is fixedly installed on the inclined surface of the second wedge block and the first wedge block, which are in contact and slide together.

[0012] Preferably, a limiting guide rod is fixedly installed inside the locking box, the moving plate and the wedge block are slidably disposed on the outer surface of the limiting guide rod, an elastic element is fixedly installed at the bottom of the wedge block, and the end of the elastic element is fixedly installed on the inner wall of the locking box.

[0013] Preferably, each of the two ground support rods is equipped with a protective airbag, and a vent pipe is fixedly installed on the side of the protective airbag. The other end of the vent pipe passes through the locking box and extends into the interior of the locking box.

[0014] Preferably, a magnetic block one is fixedly installed on the top of the movable sealing plate, and a matching magnetic block two is provided on the inner wall of the landing box opposite the movable sealing plate.

[0015] Working principle: The test box is placed between multiple clamping and fixing rods. The drive motor drives the adjustment plate to rotate. The rotation of the adjustment plate drives the sliding rod to slide inside the arc-shaped channel. When the sliding rod moves, it cooperates with the anti-deviation rod to drive the multiple clamping and fixing rods to move closer to each other, thereby achieving the clamping and fixing of the test box. During the flight of the drone, an exhaust fan draws outside air into the detection chamber. A dust monitor is used to monitor the drawn-in gas in real time to determine the current air quality. The detected gas can be discharged through the exhaust pipe, thus realizing the monitoring of the gas. When the main body of the drone malfunctions and the coil is de-energized, the fixed plate and the moving iron core will be driven by the elastic element to move the connecting rod back to its original position. The movement of the connecting rod will cause the piercing needle to move synchronously through the support plate. The movement of the piercing needle will puncture the compressed gas cylinder, releasing the compressed gas inside the cylinder. The release of the compressed gas can drive the parachute to deploy quickly, thus enabling the parachute to open rapidly. After the parachute opens, the movable sealing plate moves to the release port under the action of the parachute, sealing the release port and thus sealing the internal compressed gas. The remaining gas will enter the locking box, driving the movable plate to move downward. The movement of the movable plate will drive the first wedge block to move synchronously. As the first wedge block moves, it will drive multiple second wedge blocks to move away from each other. The movement of the second wedge block will drive the toothed plate to move synchronously through the drive rod. The toothed plate will move to mesh with the gear, realizing the locking of the gear, and further realizing the locking of the propeller on the main body of the drone. After the propeller is locked, the remaining compressed gas can enter the protective airbag through the vent pipe to inflate the airbag and make it expand. This airbag acts as a buffer to protect the drone body after it falls, further reducing the damage to the drone body.

[0016] This invention provides a dust monitoring device mounted on a drone. It has the following beneficial effects: 1. This invention comprises a landing box, a partition plate, a parachute, a movable sealing plate, a sealing cover, and a parachute deployment assembly. The parachute deployment assembly drives the parachute to deploy rapidly, and the movable sealing plate moves towards the release port under the action of the parachute deployment assembly, causing the parachute to detach from the storage area. The sealing cover opens simultaneously under force, thus releasing the parachute. This invention is used for emergency landing when the drone body encounters an accident, reducing damage to the drone body.

[0017] 2. This invention, by setting up a compressed gas cylinder, a drive assembly, a connecting rod, a support plate, and a piercing needle, uses the drive assembly to drive the connecting rod to move. The movement of the connecting rod drives the piercing needle to move synchronously through the support plate. The movement of the piercing needle punctures the compressed gas cylinder, releasing the compressed gas inside. The release of the compressed gas can drive the parachute to deploy rapidly, quickly realizing the opening of the parachute. This can quickly realize the anti-fall function of the drone body when the main body malfunctions.

[0018] 3. This invention, by setting up an installation shell, coil, stationary iron core, moving iron core, fixing plate, and elastic element one, allows the stationary iron core to drive the moving iron core to move when the coil is energized. This causes the moving iron core to drive the connecting rod to move, and the movement of the connecting rod, through the support plate, drives the piercing needle to move away from the compressed gas cylinder. In the event of an accident involving the drone body, after the coil is de-energized, the fixing plate and the moving iron core, under the action of the elastic element one, will drive the moving iron core back to its original position and drive the piercing needle to move closer to the compressed gas cylinder, thus achieving the piercing and release operation of the compressed gas cylinder.

[0019] 4. This invention, by setting up a locking box, a moving plate, wedge block one, wedge block two, a drive rod, a gear, and a toothed plate, allows the moving plate to move to the release port under the action of the parachute when the compressed gas cylinder releases compressed gas. This seals the release port, thereby blocking the internal compressed gas. The remaining gas enters the locking box, driving the moving plate downwards. The movement of the moving plate causes wedge block one to move synchronously. As wedge block one moves, multiple wedge blocks two move away from each other. The movement of wedge blocks two drives the toothed plate to move synchronously via the drive rod. The toothed plate moves to mesh with the gear, locking the gear and further locking the propeller on the UAV body. This prevents the propeller from continuing to rotate and getting entangled in the parachute, and also prevents the airflow generated by the rotating propeller from disturbing the parachute and causing it to sway and become unstable.

[0020] 5. By setting up a vent pipe and a protective airbag, after the propeller is locked, the remaining compressed gas can enter the protective airbag through the vent pipe to inflate the protective airbag, thereby expanding the protective airbag and providing a buffer protection effect after the drone body falls, further reducing the damage to the drone body.

[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a dust monitoring device mounted on a drone, including a drone body 1, two ground support poles 2 fixedly installed at the bottom of the drone body 1, and protective frames 5 fixedly installed on multiple propellers of the drone body 1. The main body 1 of the drone is equipped with a landing and anti-fall mechanism 3, which includes a landing box 301. A partition plate 303 is fixedly installed inside the landing box 301, dividing the interior of the landing box 301 into a storage area 1 and a storage area 2. A movable sealing plate 306 is provided inside the storage area 1. A drop port is opened on the top of the landing box 301 facing the storage area 1. A sealing cover 302 that works with the drop port is installed on the landing box 301. A parachute 304 is provided inside the storage area 1 and is fixedly connected to the movable sealing plate 306. An opening component for quickly opening the parachute 304 is provided inside the storage area 2.

[0025] By setting up a landing box 301, a partition plate 303, a parachute 304, a movable sealing plate 306, a sealing cover 302, and a parachute opening assembly, the parachute 304 is rapidly deployed by the parachute opening assembly. The movable sealing plate 306 moves towards the release port under the action of the parachute opening assembly, causing the parachute 304 to detach from the storage area. The sealing cover 302 opens simultaneously under force, realizing the release of the parachute 304. This is used for emergency landing when the drone encounters an accident, reducing damage to the drone.

[0026] The bottom of the drone body 1 is equipped with a dust monitoring mechanism 4. The dust monitoring mechanism 4 includes a mounting box 401. Multiple clamping and fixing rods 406 are slidably mounted on the mounting box 401, and a detection box 407 is provided between the multiple clamping and fixing rods 406. A dust monitoring instrument 409 is fixedly installed inside the detection box 407. An air inlet is opened at the bottom of the detection box 407 and an exhaust fan 408 is installed at the air inlet. An exhaust pipe 410 is installed on the detection box 407 and a control valve is provided on the exhaust pipe 410.

[0027] By setting up an installation box 401, a clamping and fixing rod 406, a detection box 407, a dust monitor 409, an exhaust fan 408, and an exhaust pipe 410, the exhaust fan 408 can draw outside air into the detection box 407, the dust monitor 409 can monitor the drawn-in gas in real time to determine the current air quality, and the detected gas can be discharged through the exhaust pipe 410, thus realizing the monitoring of the gas. The installation box 401 and the clamping and fixing rod 406 work together to quickly install and disassemble the detection box 407, which is convenient for subsequent maintenance and replacement.

[0028] For details, please refer to the appendix. Figure 7 and attached Figure 8 The umbrella opening assembly includes multiple compressed gas cylinders 305 fixed inside the storage area 2. Multiple connecting rods 315 are slidably provided on the partition plate 303. Support plates 313 are fixedly installed at the ends of the multiple connecting rods 315. Puncture needles 314 are fixedly installed on the support plates 313 at positions directly opposite the multiple compressed gas cylinders 305. Multiple drive components for driving the connecting rods 315 to move are provided inside the storage area 2.

[0029] By setting up a compressed gas cylinder 305, a drive assembly, a connecting rod 315, a support plate 313, and a piercing needle 314, the drive assembly drives the connecting rod 315 to move. The movement of the connecting rod 315 drives the piercing needle 314 to move synchronously through the support plate 313. The movement of the piercing needle 314 punctures the compressed gas cylinder 305, releasing the compressed gas inside. The release of the compressed gas can drive the parachute 304 to deploy quickly, thus rapidly opening the parachute 304. This allows for rapid anti-fall protection of the UAV body 1 in the event of a malfunction.

[0030] For details, please refer to the appendix. Figure 7 and attached Figure 8 The drive assembly includes a mounting housing 307 fixed inside the storage area 2. A coil 308 is fixed inside the mounting housing 307. A stationary iron core 309 is provided inside the coil 308 and is fixed inside the mounting housing 307. A moving iron core 310 that cooperates with the stationary iron core 309 is slidably provided on the mounting housing 307. The moving iron core 310 is fixedly connected to a corresponding connecting rod 315. A fixing plate 312 is installed at the end of the moving iron core 310, and an elastic element 311 is installed on the side of the fixing plate 312. The end of the elastic element 311 is fixed on the mounting housing 307.

[0031] By configuring the housing 307, coil 308, stationary iron core 309, moving iron core 310, fixing plate 312, and elastic element 311, when the coil 308 is energized, the stationary iron core 309 drives the moving iron core 310 to move, causing the moving iron core 310 to drive the connecting rod 315 to move. The movement of the connecting rod 315 drives the piercing needle 314 to move through the support plate 313, moving the piercing needle 314 away from the compressed gas cylinder 305. In the event of an accident involving the drone body 1, after the coil 308 is de-energized, the fixing plate 312 and the moving iron core 310, under the action of the elastic element 311, drive the moving iron core 310 back to its original position, driving the piercing needle 314 to move closer to the compressed gas cylinder 305, thereby achieving the piercing and release operation of the compressed gas cylinder 305.

[0032] For details, please refer to the appendix. Figure 9 and attached Figure 10 The installation box 401 has a drive motor 402 fixedly installed inside. The output shaft of the drive motor 402 is fixedly installed with an adjustment plate 403. The adjustment plate 403 has multiple arc-shaped channels. The top of the clamping and fixing rod 406 is equipped with an anti-deviation rod 405. The anti-deviation rod 405 is slidably arranged in the slide rail opened on the installation box 401. The top of the anti-deviation rod 405 is fixedly installed with a sliding rod 404. The sliding rod 404 is slidably arranged in the corresponding arc-shaped channel.

[0033] By setting up a drive motor 402, an adjusting plate 403, an anti-deviation rod 405, and a sliding rod 404, the drive motor 402 drives the adjusting plate 403 to rotate. The rotation of the adjusting plate 403 drives the sliding rod 404 to slide inside the arc-shaped channel. When the sliding rod 404 moves, it cooperates with the anti-deviation rod 405 to drive multiple clamping and fixing rods 406 to move closer or further apart, thereby achieving the clamping and fixing of the testing box 407. This allows for quick and easy mounting and dismounting of the testing box 407, and provides high stability, making it suitable for testing boxes 407 of different specifications.

[0034] For details, please refer to the attached diagram. Figure 5 and attached Figure 6 The bottom of the landing box 301 is provided with a locking mechanism 6. The locking mechanism 6 includes a locking box 601 fixedly installed between the landing box 301 and the drone body 1. Gears 609 are fixedly installed on the shafts of multiple propellers of the drone body 1. Multiple drive rods 608 are slidably provided on the locking box 601. A toothed plate 610 that cooperates with the gears 609 is fixedly installed at the end of the drive rod 608.

[0035] For details, please refer to the attached diagram. Figure 5 and attached Figure 7A vent is provided at the connection between the locking box 601 and the landing box 301. A movable plate 602 is slidably installed inside the locking box 601. A wedge block 603 is fixedly installed at the bottom of the movable plate 602. A wedge block 604 that cooperates with the wedge block 603 is fixedly installed at the end of the movable plate 602 near the wedge block 603.

[0036] By setting up a locking box 601, a moving plate 602, a first wedge block 603, a second wedge block 604, a drive rod 608, a gear 609, and a toothed plate 610, when the compressed gas cylinder 305 releases compressed gas, after the parachute 304 opens, the moving sealing plate 306 moves to the release port under the drive of the parachute 304 to block the release port, thereby blocking the internal compressed gas. The remaining gas will enter the locking box 601, driving the moving plate 602 to move downward. The movement of the moving plate 602 will drive the first wedge block 603 to move synchronously. While the first wedge block 603 moves, it will drive multiple second wedge blocks 604 to move away from each other. The movement of the second wedge block 604 will drive the toothed plate 610 to move synchronously through the drive rod 608. The toothed plate 610 moves to mesh with the gear 609, thereby locking the gear 609. To further achieve the locking of the propeller on the main body 1 of the UAV, the propeller is prevented from continuing to rotate and getting entangled in the parachute 304. At the same time, the airflow generated by the rotation of the propeller is prevented from disturbing the parachute 304 and causing the parachute 304 to shake and become unstable.

[0037] For details, please refer to the appendix. Figure 6 and attached Figure 7 A trapezoidal slider 605 is fixedly installed on the inclined surface of wedge block 2 604 that slides against wedge block 1 603. A trapezoidal groove is provided on the inclined surface of wedge block 1 603, and the trapezoidal slider 605 is slidably disposed inside the trapezoidal groove.

[0038] By setting a trapezoidal slider 605, the trapezoidal slider 605 slides inside the trapezoidal groove, which is used to prevent the trapezoidal slider 605 from falling off. At the same time, it is used to ensure that the second wedge block 604 can always be in contact with the first wedge block 603, so as to prevent the drive stick 608 from shaking or moving during the flight of the drone body 1.

[0039] For details, please refer to the appendix. Figure 3 - Appendix Figure 5 A limiting guide rod 606 is fixedly installed inside the locking box 601. A movable plate 602 and a wedge block 603 are slidably disposed on the outer surface of the limiting guide rod 606. An elastic element 607 is fixedly installed at the bottom of the wedge block 603, and the end of the elastic element 607 is fixedly installed on the inner wall of the locking box 601.

[0040] By setting a limiting guide rod 606 and an elastic element 607, the limiting guide rod 606 limits and guides the moving plate 602 and the wedge block 603 to avoid deviation during their movement. The elastic element 607 applies pressure to the wedge block 603 to keep the wedge block 603 and the moving plate 602 in their original positions, thus avoiding affecting the normal flight operation of the UAV body 1.

[0041] For details, please refer to the appendix. Figure 1 - Appendix Figure 4 Each of the two ground support rods 2 is equipped with a protective airbag 612. A ventilation pipe 611 is fixedly installed on the side of the protective airbag 612. The other end of the ventilation pipe 611 passes through the locking box 601 and extends into the interior of the locking box 601.

[0042] By setting up the vent pipe 611 and the protective airbag 612, after the propeller is locked, the remaining compressed gas can enter the protective airbag 612 through the vent pipe 611 to inflate the protective airbag 612, so that the protective airbag 612 expands and plays a buffering role after the drone body 1 falls, further reducing the damage to the drone body 1.

[0043] For details, please refer to the appendix. Figure 7 A magnetic block 316 is fixedly installed on the top of the movable sealing plate 306, and a magnetic block 317 for matching use is provided on the inner wall of the landing box 301 opposite to the movable sealing plate 306.

[0044] By setting up magnetic block 316 and magnetic block 317, when the moving sealing plate 306 moves upward, the stability between the moving sealing plate 306 and the landing box 301 can be improved by using magnetic block 316 and magnetic block 317, so as to avoid the problem of the moving sealing plate 306 swaying up and down, and further ensure the stability of use.

[0045] Working principle: The test box 407 is placed between multiple clamping and fixing rods 406. The drive motor 402 drives the adjusting plate 403 to rotate. The rotation of the adjusting plate 403 drives the sliding rod 404 to slide inside the arc-shaped channel. When the sliding rod 404 moves, it cooperates with the anti-deviation rod 405 to drive the multiple clamping and fixing rods 406 to move closer to each other, thereby achieving the clamping and fixing of the test box 407. During the flight of the main body 1 of the drone, the exhaust fan 408 can draw outside air into the detection box 407, and the dust monitor 409 can monitor the drawn-in gas in real time to determine the current air quality. The detected gas can be discharged through the exhaust pipe 410 to realize the monitoring of the gas. When the main body of the drone 1 malfunctions, after the coil 308 is de-energized, the fixed plate 312 and the moving iron core 310 will be driven by the elastic element 311 to move the connecting rod 315 back to its original position. The movement of the connecting rod 315 will drive the piercing needle 314 to move synchronously through the support plate 313. The movement of the piercing needle 314 will pierce the compressed gas cylinder 305, releasing the compressed gas inside the compressed gas cylinder 305. The release of the compressed gas can drive the parachute 304 to deploy quickly, thus quickly realizing the opening of the parachute 304. After the parachute 304 opens, the movable sealing plate 306 moves to the release port under the drive of the parachute 304 to block the release port, thereby blocking the internal compressed gas. The remaining gas will enter the locking box 601, driving the movable plate 602 to move downward. The movement of the movable plate 602 will drive the first wedge block 603 to move synchronously. While the first wedge block 603 moves, it will drive multiple second wedge blocks 604 to move away from each other. The movement of the second wedge block 604 will drive the toothed plate 610 to move synchronously through the drive rod 608. The toothed plate 610 moves to mesh with the gear 609, realizing the locking of the gear 609, and further realizing the locking of the propeller on the main body of the UAV 1. After the propeller is locked, the remaining compressed gas can enter the protective airbag 612 through the vent pipe 611 to inflate the protective airbag 612, causing it to expand and buffer the drone body 1 after it falls, further reducing the damage to the drone body 1.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
