Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a UAV used for comprehensive management of high-risk areas of forest and grassland fires. Background Technology

[0002] After forest fires, industrial fires, and large building fires are extinguished, post-disaster assessment and monitoring are crucial, directly impacting the prevention of reignition, investigation of the cause of the accident, and the smooth progress of post-disaster reconstruction. Traditional post-disaster assessments mainly rely on personnel conducting in-depth on-site investigations. However, fire environments are complex, often posing secondary risks such as building collapses and smoldering at high temperatures, which greatly threaten the personal safety of investigation personnel.

[0003] Currently, while some general-purpose drones on the market are being tested for fire monitoring, their application in the special environment of a fire scene has significant limitations. First, ordinary drones lack effective heat insulation, making it difficult to hover and operate for extended periods in areas still experiencing high-temperature embers; their onboard electronic equipment is prone to malfunction due to overheating. Second, conventional monitoring drones have limited functionality, typically equipped only with visible light cameras, unable to effectively penetrate smoke, identify underground smoldering fire points, or accurately measure residual temperature, making it difficult to provide comprehensive and accurate post-disaster assessment data. Furthermore, existing equipment has fixed monitoring angles, blind spots, and lacks the ability to collect physical samples, still requiring human intervention when evidence collection and analysis are needed.

[0004] Therefore, there is an urgent need in this field for an integrated and professional unmanned aerial vehicle (UAV) system that can overcome harsh high-temperature environments and integrate multiple functions such as multi-sensor fusion detection, flexible observation, sample capture, and active cooling protection to meet the needs of efficient, safe, and comprehensive post-fire on-site assessment. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one aspect of the purpose of this utility model is to provide a drone for comprehensive management of high-risk areas of forest and grassland fires. The drone includes a main unit, flight components, monitoring components, assessment components, a signal transmitter, a cooling device, fog lights, and a mechanical gripper. The flight components are arranged in four sets and are fixedly arranged on the four sides of the main unit. The monitoring components are arranged on the top of the main unit. The signal transmitter is arranged on the top of the main unit. The cooling device is arranged on the bottom of the main unit. The assessment components are arranged on the side of the cooling device away from the bottom of the main unit. The fog lights are arranged on the four sides of the main unit. The mechanical gripper is arranged on the two symmetrical sides of the main unit. The flight components include a motor, a support frame, wings, rotating parts, a windproof frame, and a fixed bracket. The motor is fixed in the windproof frame by the support frame. There are at least two support frames. The wings are hinged to the output end of the motor by the rotating parts. There are at least two wings. The windproof frame is fixedly arranged on the side of the main unit by the fixed bracket.

[0006] Preferably, the monitoring component includes a monitoring camera, a folding support frame, and a turntable. The monitoring camera is hinged to the folding support frame, and the end of the folding support frame away from the monitoring camera is fixedly mounted on the turntable. The turntable is hinged to the top of the host unit.

[0007] Preferably, the evaluation components include a temperature tester, a wind power tester, a horizontal height measuring instrument, a GPS locator, a smoke and fire monitoring and alarm camera, and a fire thermal imager. The temperature tester, wind power tester, horizontal height measuring instrument, GPS locator, smoke and fire monitoring and alarm camera, and fire thermal imager are evenly spaced and arranged on the side of the cooling device away from the bottom of the main unit.

[0008] Preferably, the outer surfaces of the drone that come into contact with the outside world are provided with heat insulation film.

[0009] Preferably, the mechanical gripper includes a telescopic rod and a gripper, and the gripper is fixedly connected to the host via the telescopic rod.

[0010] Preferably, the four sets of motors are arranged opposite each other, with two rotating in the forward direction and two rotating in the reverse direction.

[0011] Preferably, the drone also includes a landing frame, which is fixedly mounted on both symmetrical sides of the main unit.

[0012] The beneficial effects of this utility model are as follows: It has achieved comprehensive and accurate unmanned post-fire assessment: By integrating multi-dimensional sensors such as visible light monitoring, thermal imaging, temperature, wind force, and smoke monitoring, a three-dimensional air-to-ground reconnaissance system has been constructed. It can simultaneously complete visible light image recording, precise location of residual high temperature points, environmental parameter collection, and re-ignition risk assessment. It can complete the assessment work that traditionally relies on manpower and is completed in multiple batches in one go, which greatly improves the comprehensiveness and accuracy of the assessment.

[0013] Significantly enhances the equipment's survivability and operational capabilities in harsh environments: The heat insulation film covering the entire outer surface of the drone, combined with the unique active cooling device at the bottom of the main unit, forms a dual protection mechanism of "passive defense" and "active cooling." This enables the equipment to penetrate deep into the core area of ​​a fire where there are still high-temperature embers for long-term, close-range reconnaissance operations, solving the key technical bottleneck of ordinary drones malfunctioning or being damaged due to high temperatures.

[0014] Enhanced reconnaissance flexibility and sample acquisition capabilities: The articulated folding support frame and turntable structure enable 360-degree omnidirectional adjustment of the surveillance camera's tilt and horizontal angles, completely eliminating blind spots. Combined with retractable mechanical grippers on both sides of the main unit, the drone can not only "see" but also "grab," achieving non-contact remote acquisition of key evidence. This provides direct physical evidence for fire investigations and avoids the need for personnel to risk re-entry.

[0015] It ensures flight stability and data transmission reliability: The design of four opposing forward and reverse motors effectively counteracts the reverse torque, making the flight attitude more stable and providing a stable platform for high-definition shooting and data acquisition. At the same time, the top-mounted signal transmitter ensures that all key data and images can be transmitted to the command center in real time and stably in complex environments, ensuring the timeliness and scientific nature of rear decision-making.

[0016] It possesses excellent all-weather and complex weather conditions operating capabilities: The large fog lights on all four sides of the main unit ensure operational safety and reconnaissance effectiveness in low-visibility environments such as nighttime, dense smoke, or heavy fog. The windproof frame design of the flight components enhances its resistance to wind disturbances, ensuring stable flight even in turbulent airflows that may occur after a fire.

[0017] Additional aspects and advantages of this invention will become apparent from the description which follows, or may be learned by practice of this invention. Attached Figure Description

[0021] This utility model of a drone for comprehensive management of high-risk forest and grassland fire areas includes a main unit 1, flight components 2, motor 21, support frame 22, wings 23, rotating parts 24, windproof frame 25, fixed bracket 26, monitoring components 3, monitoring camera 31, folding support frame 32, turntable 33, evaluation components 4, temperature tester 41, wind force tester 42, horizontal height measuring instrument 43, GPS positioning device 44, smoke and fire monitoring and alarm camera 45, fire thermal imager 46, signal transmitter 5, cooling device 6, fog light 7, mechanical gripper 8, telescopic pole 81, gripper 82, and landing frame 9.

[0022] like Figure 1-4 As shown, four sets of flight components 2 are fixedly installed at the four corners of the main unit 1. The monitoring camera 31 is hinged to the folding support frame 32. The end of the folding support frame 32 away from the monitoring camera 31 is fixedly installed on the turntable 33. The turntable 33 is hinged to the top of the main unit 1. The signal transmitter 5 is installed on the top of the main unit 1. The cooling device 6 is installed at the bottom of the main unit 1. The temperature tester 41, wind tester 42, horizontal altimeter 43, GPS locator 44, smoke and fire monitoring alarm camera 45, and fire thermal imager 46 are evenly spaced and installed on the side of the cooling device 6 away from the bottom of the main unit 1. The fog light 7 is installed on the main unit 1. On the four sides, mechanical grippers 8 are set on the symmetrical sides of the main unit 1. The grippers 82 are fixedly connected to the main unit 1 through telescopic rods 81. The motors 21 are fixed inside the windproof frame 25 through support frames 22. There are at least two support frames 22. The wings 23 are hinged to the output end of the motors 21 through rotating parts 24. There are at least two wings 23. The windproof frame 25 is fixedly set on the side of the main unit 1 through fixed brackets 26. Two of the four sets of motors 21 rotate forward and two rotate in reverse. The motors 21 with the same direction of rotation are set opposite each other. The outer surface of the drone in contact with the outside world is covered with heat insulation film. The landing frame 9 is fixedly set on the symmetrical sides of the main unit 1.

[0023] First, the four flight components 2 are activated. By controlling two sets of forward-rotating and two sets of reverse-rotating opposing motors 21, the UAV can fly smoothly to the fire area. The heat insulation film on the surface of the aircraft can effectively resist the high temperature of the embers and ensure flight safety. The GPS positioning device 44 is used to accurately navigate to the target coordinates, and the horizontal altimeter 43 is used to maintain stable hovering or low-speed cruising in order to conduct detailed surveys.

[0024] Environmental parameter measurement: After flying over the fire site, the evaluation component 4 at the bottom of the main unit is activated. The temperature tester 41 is used to monitor the residual temperature of the ground and air in real time and identify potential reignition points. The wind tester 42 assesses the wind force and direction at the scene to provide data for judging the risk of fire spread.

[0025] Disaster image recording: Macro monitoring, through the monitoring camera 31 on the top of the host, a wide range of observation can be carried out. The height and angle of the folding support frame 32 can be flexibly adjusted, and the turntable 33 can be driven to rotate 360° to record panoramic and multi-angle video and images of the disaster site.

[0026] Precise detection: The smoke and fire monitoring and alarm camera 45 at the bottom continuously scans to ensure that there are no new open flames or smoke, while the fire thermal imager 46 penetrates the smoke to accurately capture underground smoldering or high-temperature points inside the wall that cannot be detected by the naked eye, thus completely eliminating hidden dangers.

[0027] Auxiliary operations: In low-visibility environments at night or when smoke has not yet dissipated, the large fog lights 7 on all four sides of the main unit can be turned on to ensure clear and safe reconnaissance operations.

[0028] Sample grabbing and evidence collection: If further analysis of specific residues (such as burned building materials, molten material, etc.) is required, the mechanical grippers 8 on both sides of the main unit can be operated to control the telescopic rod 81 to extend to the target position, and then the gripper 82 can be used to safely grab the sample and bring it back to provide physical evidence for the investigation of the cause of the fire.

[0029] Assisting in firefighting and rescue: In firefighting scenarios, the mechanical gripper 8 can be used to grab and drop small fire extinguishing devices or rescue supplies.

[0030] Data processing and real-time transmission: Throughout the assessment process, all sensor data, high-definition video, thermal imaging images, and GPS positioning information are transmitted back to the command center in real time via the signal transmitter 5 on the top of the main unit. This ensures that the command center can obtain a comprehensive and accurate on-site assessment report as soon as possible, providing decision support for post-disaster reconstruction and accident identification.

[0031] Equipment self-protection: When operating in the high-temperature residual area for a long time, the cooling device 6 can be activated to provide active cooling for the densely packed monitoring instruments and main unit at the bottom, ensuring the equipment can continue to operate stably in harsh environments and preventing overheating damage.

[0032] Comprehensive heat insulation: Because all exposed surfaces of the drone are covered with heat insulation film, it can briefly pass through or hover in high-temperature areas, providing key equipment safety protection for tasks such as fire monitoring and fire scene reconnaissance.

[0033] The above description only describes the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
