Description

Technical Field

[0001] This invention relates to the field of hazardous materials detection technology, specifically to a drone device for hazardous materials detection. Background Technology

[0002] Hazardous materials exploration is a high-risk task requiring extremely high precision. Traditional exploration methods often rely on manual field investigations, which are not only inefficient but also pose significant personnel safety risks. The limitations of manual exploration are particularly pronounced in situations involving complex terrain, harsh weather, or potentially explosive environments.

[0003] A search revealed Chinese patent CN105067644A, which discloses a method for identifying liquid hazardous materials using an X-ray inspection system, relating to the field of hazardous materials detection technology. It includes an input device for receiving image data and a logic processing unit. The specific database establishment process and matching steps are as follows: First, a database of common liquid parameters is established. Each liquid in the database contains six parameters: density, average mass decay coefficient of the high and low energy components, the product of the average mass decay coefficient of the high and low energy components and the density, and the effective atomic number. Then, the data obtained from detecting unknown liquids is compared and matched with the parameters in the database. This invention can quickly detect and identify liquid hazardous materials and is simple and easy to operate.

[0004] A search revealed Chinese patent CN210616523U, which discloses a hazardous materials detection robot. The robot includes a walking device and a rotating base, a telescopic arm, and a gripper, all sequentially connected to the top of the walking device. The walking device forms the main body of the robot and drives its movement. The rotating base adjusts the gripper's horizontal rotation and pitch. The telescopic arm adjusts the gripper's extension length. The gripper grasps a target object. An X-ray generator is located at the front of the walking device and generates X-rays. A detector receives the X-rays emitted by the generator. A support device supports the X-ray generator and the detector. A data transmission module transmits the processed image information of the target object's interior to a central control module in real time. This invention utilizes X-rays to detect items, meeting the requirements for rapid response.

[0005] However, existing hazardous materials detection devices generally require personnel to approach the vicinity of the hazardous materials before installing the equipment for detection. In this process, not only is the health of the user threatened, but when the hazardous materials are present in a large area, the detection area cannot be completely covered because the detection device is generally in a fixed position. Based on this, the present invention designs a drone device for hazardous materials detection to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a drone device for detecting hazardous materials, which solves the problem of insufficient coverage of the detection area in the prior art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A drone device for detecting hazardous materials includes: A support base, the top of which is equipped with a rotating mechanism for rotating the top detection structure to enable the detection of hazardous materials in different directions; The detection mechanism is installed on top of the rotating mechanism and is used for the detection of hazardous materials. The detection mechanism includes a drive component, a linkage component, and an exploration component. The drive component is installed on top of the rotating mechanism and is used for the movement of the thermal imaging structure. The linkage component is installed on one side of the drive component and is used for the simultaneous movement of the thermal imaging components on both sides. The exploration component is installed on one side of the drive component and is used for the detection of gas concentration. Both sides of the support base are equipped with drive fan blades and external drive structures. The drive fan blades are distributed in multiple matrix arrays.

[0008] The drone achieves flight and stable hovering through a drive structure powered by its bottom-mounted drive blades, providing an aerial platform for inspection operations. The control system adjusts flight altitude and direction to ensure comprehensive inspection of the target area. Upon reaching the inspection area, the rotating mechanism activates, with the drive motor rotating the active bevel gear. This, in turn, meshes with the linkage bevel gear, causing the connecting column and its top support frame to rotate. This design ensures the inspection mechanism can detect hazardous materials from different directions, improving inspection efficiency and coverage.

[0009] Preferably, the rotating mechanism includes a connecting column mounted on the top of the support base, a linkage bevel gear mounted on the outer ring of the connecting column, a drive motor mounted on the top of the support base, a drive shaft fixedly connected to the output shaft of the drive motor, a driving bevel gear mounted on the outer ring of the drive shaft, the driving bevel gear meshing with the linkage bevel gear, and a support frame mounted on the top of the connecting column.

[0010] Preferably, a connecting plate is installed on the outer wall of the support frame, and a connecting fan blade is installed on the top of the connecting plate. Both the connecting plate and the connecting fan blade are distributed in multiple sets of circumferential arrays.

[0011] Preferably, the drive assembly includes a dual-axis motor mounted on one side of the support frame, with a drive screw fixedly connected to the bottom output shaft of the dual-axis motor. A connecting screw is also mounted on one side of the support frame. A moving plate is threadedly connected to the outer ring of the drive screw and the connecting screw. A first thermal imager is mounted on one side of the moving plate. The drive assembly also includes a linkage screw mounted on the other side of the support frame, with a lifting plate threadedly connected to the outer ring of the linkage screw. A second thermal imager is mounted on one side of the lifting plate.

[0012] The dual-axis motor serves as the power source, driving the drive screw and connecting screw to rotate synchronously. Through threaded engagement, the moving plate moves vertically, driving the first thermal imager to perform infrared thermal imaging scanning. At the same time, the linkage screw rotates synchronously under the belt connection, causing the lifting plate to drive the second thermal imager to move vertically. This design enables the thermal imager to scan flexibly in the vertical direction, improving accuracy.

[0013] Preferably, the linkage assembly includes a rotating rod mounted on the top of the dual-axis motor and the connecting lead screw. The output shaft of the dual-axis motor is fixedly connected to the rotating rod via a coupling. The connecting lead screw and the rotating rod are fixedly connected via a flange. A rotating roller is mounted on the top of the rotating rod, and a belt is mounted on the outer ring of the rotating roller.

[0014] Preferably, the drive screw and the linkage screw are also connected by a belt, and a linkage roller is installed on the top of the linkage screw and the linkage rollers are connected by a belt.

[0015] Preferably, the exploration component includes a protective frame installed in the inner cavity of the support frame. An electric push rod is fixedly connected to the inner wall of the protective frame. A movable block is fixedly connected to the output end of the electric push rod. The movable block has a wedge-shaped structure that is narrow at the front and wide at the back. A gas detector is installed on the front of the movable block.

[0016] During the thermal imaging scan, the exploration component begins to work. The electric push rod pushes the moving block and gas detector forward to detect the gas concentration in the suspected hazardous area. The wedge-shaped structure of the moving block, combined with the telescopic rod and spring, ensures both flexibility during detection and protection of the gas detector after detection.

[0017] Preferably, the exploration component further includes a telescopic rod installed on the inner wall of the protective frame. A connecting frame is installed on one side of the telescopic rod, and a spring is installed on the outer ring of the telescopic rod. One side of the spring is fixedly connected to the connecting frame, and the other side of the spring is fixedly connected to the connecting frame.

[0018] Preferably, a fixing seat is installed on the top of the support frame, a photovoltaic panel is installed on the top of the fixing seat, a storage battery is installed in the inner cavity of the support seat, and the photovoltaic panel and the storage battery are electrically connected.

[0019] The photovoltaic panels continuously charge the batteries, ensuring the power supply for the drone during long-term operations. When suspected hazardous materials are detected, the infrared features captured by the thermal imager and the gas concentration data detected by the gas detector are comprehensively analyzed to accurately determine the type and storage location of the hazardous materials.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This invention utilizes infrared thermal imaging analysis to identify the unique infrared characteristics of hazardous materials. Combined with atmospheric composition detection equipment, it further confirms the composition and storage location of hazardous chemicals. The combination of these two functions not only improves the accuracy of detection but also enables accurate determination of the type of hazardous materials based on comprehensive analysis of infrared characteristics and gas concentration data. The design of the drive and linkage components enables synchronous movement of the thermal imager in the vertical direction, greatly improving the flexibility and accuracy of thermal imaging scanning and ensuring comprehensive detection of suspected hazardous material areas.

[0021] 2. This invention utilizes an aerial drone platform equipped with infrared thermal imaging and atmospheric composition detection equipment to achieve remote, non-contact hazardous materials detection. This improvement avoids the need for personnel to come into close contact with hazardous materials, thereby greatly reducing the health and safety risks that may be faced during the detection process. The drone has the ability to fly and hover, and can flexibly adjust its flight altitude and direction through the control system to conduct all-round detection of the target area. At the same time, the design of the rotating mechanism enables the detection device to detect hazardous materials from different directions, greatly improving detection efficiency and coverage, and solving the problem of blind spots caused by the fixed position of existing detection devices.

[0022] 3. The design of the electric push rod, telescopic rod, and spring combination structure in the exploration component of this invention not only ensures the stability and flexibility of the gas detector during detection, but also protects the gas detector after detection, avoiding equipment failure caused by accidental collisions or damage; the photovoltaic panel installed on the top of the drone equipment can continuously charge the battery, ensuring the power supply of the drone during long-term operation.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0027] Please see Figures 1-9 In this embodiment of the invention, a drone device for detecting hazardous materials includes: Support base 101, the top of support base 101 is equipped with a rotating mechanism 1 for rotating the top detection structure, so as to realize the detection of dangerous goods in different directions; The detection mechanism 2 is installed on top of the rotating mechanism 1 and is used for the detection of hazardous materials. The detection mechanism 2 includes a drive assembly 3, a linkage assembly 4 and an exploration assembly 5. The drive assembly 3 is installed on top of the rotating mechanism 1 and is used for the movement of the thermal imaging structure. The linkage assembly 4 is installed on one side of the drive assembly 3 and is used for the simultaneous movement of the thermal imaging assemblies on both sides. The exploration assembly 5 is installed on one side of the drive assembly 3 and is used for the detection of gas concentration. Both sides of the support base 101 are equipped with drive fan blades 102 and external drive structures. The drive fan blades 102 are distributed in multiple matrix arrays.

[0028] The rotating mechanism 1 includes a connecting column 103 mounted on the top of the support base 101, a linkage bevel gear 105 mounted on the outer ring of the connecting column 103, a drive motor 106 mounted on the top of the support base 101, a drive shaft 107 fixedly connected to the output shaft of the drive motor 106, a driving bevel gear 108 mounted on the outer ring of the drive shaft 107, the driving bevel gear 108 meshing with the linkage bevel gear 105, and a support frame 109 mounted on the top of the connecting column 103.

[0029] A connecting plate 110 is installed on the outer wall of the support frame 109, and a connecting fan blade 111 is installed on the top of the connecting plate 110. Both the connecting plate 110 and the connecting fan blade 111 are distributed in multiple sets of circular arrays.

[0030] The working principle of this invention is as follows: When the drone arrives above the detection area, the rotating mechanism 1 starts working. The drive motor 106 starts, driving the drive shaft 107 to rotate, which in turn causes the active bevel gear 108 to rotate. The meshing action of the active bevel gear 108 and the linkage bevel gear 105 causes the connecting column 103 and its top support frame 109 to rotate accordingly. This rotation ensures that the detection mechanism 2 installed on the support frame 109 can detect hazardous materials from different directions, greatly improving detection efficiency and coverage. During flight, the drone can adjust its altitude and direction through the control system to perform all-round detection of the target area.

[0031] Please see Figures 1-9 In this embodiment of the invention, the drive assembly 3 includes a dual-axis motor 301 mounted on one side of the support frame 109. The bottom output shaft of the dual-axis motor 301 is fixedly connected to a drive screw 302. A connecting screw 303 is also mounted on one side of the support frame 109. A moving plate 304 is threadedly connected to the outer ring of the drive screw 302 and the connecting screw 303. A first thermal imager 305 is mounted on one side of the moving plate 304. The drive assembly 3 also includes a linkage screw 306 mounted on the other side of the support frame 109. A lifting plate 307 is threadedly connected to the outer ring of the linkage screw 306. A second thermal imager 308 is mounted on one side of the lifting plate 307.

[0032] The linkage assembly 4 includes a rotating rod 401 mounted on the top of the dual-axis motor 301 and the connecting screw 303. The output shaft of the dual-axis motor 301 is fixedly connected to the rotating rod 401 via a coupling. The connecting screw 303 and the rotating rod 401 are fixedly connected via a flange. A rotating roller 402 is mounted on the top of the rotating rod 401, and a belt is mounted on the outer ring of the rotating roller 402.

[0033] The drive screw 302 and the linkage screw 306 are also connected by a belt. The top of the linkage screw 306 is equipped with a linkage roller 309, and the linkage rollers 309 are connected by a belt.

[0034] The working principle of this invention is as follows: A dual-axis motor 301 serves as the power source, with its bottom output shaft driving the drive screw 302 to rotate. Simultaneously, through a coupling connected to the rotating rod 401, it drives the connecting screw 303 to rotate synchronously. The threads on the drive screw 302 and the connecting screw 303 engage with the threaded holes of the moving plate 304, causing the moving plate 304 to move vertically under the rotation of the screw. This movement drives the synchronous movement of the first thermal imager 305, achieving infrared thermal imaging scanning of the detection area. The rotating roller 402 at the top of the rotating rod 401 is connected to the linkage roller 309 at the top of the linkage screw 306 via a belt, allowing the linkage screw 306 to rotate synchronously while driving the screw 302. The lifting plate 307 moves vertically under the action of the threads on the linkage screw 306, thereby driving the second thermal imager 308 to move up and down. This design achieves synchronous vertical movement of the first thermal imager 305 and the second thermal imager 308, greatly improving the flexibility and accuracy of thermal imaging scanning.

[0035] Please see Figures 1-9 In this embodiment of the invention, the exploration component 5 includes a protective frame 501 installed in the inner cavity of the support frame 109. An electric push rod 502 is fixedly connected to the inner wall of the protective frame 501. A moving block 503 is fixedly connected to the output end of the electric push rod 502. The moving block 503 has a wedge-shaped structure that is narrow at the front and wide at the back. A gas detector 504 is installed on the front of the moving block 503.

[0036] The exploration component 5 also includes a telescopic rod 505 installed on the inner wall of the protective frame 501. A connecting frame 506 is installed on one side of the telescopic rod 505, and a spring 507 is installed on the outer ring of the telescopic rod 505. One side of the spring 507 is fixedly connected to the connecting frame 506, and the other side of the spring 507 is fixedly connected to the connecting frame 506.

[0037] A mounting base 112 is installed on the top of the support frame 109, a photovoltaic panel 113 is installed on the top of the mounting base 112, and a storage battery 114 is installed in the inner cavity of the support base 101. The photovoltaic panel 113 and the storage battery 114 are electrically connected.

[0038] The working principle of this embodiment of the invention is as follows: During the thermal imaging scanning process, the exploration component 5 starts to work. After receiving the command, the electric push rod 502 extends, pushing the moving block 503 and the gas detector 504 on its front to move forward. The wedge-shaped structure design of the moving block 503 allows for gas concentration detection in suspected hazardous areas when the moving block 503 and the gas detector 504 are extended, while simultaneously compressing the combination structure of the telescopic rod 505 and the spring 507. After the detection is completed, the electric push rod 502 shortens, causing the moving block 503 to move backward. The originally compressed telescopic rod 505 and spring 507 return to their original state, allowing the connecting frame 506 to cover the front of the moving block 503, protecting the gas detector 504.

[0039] Working principle: The UAV achieves flight and hovering through the drive blades 102 at its bottom, providing a necessary aerial platform for the overall inspection operation. During flight, the UAV can adjust its altitude and direction via the control system to conduct comprehensive inspection of the target area.

[0040] When the drone arrives above the detection area, the rotating mechanism 1 begins to operate. The drive motor 106 starts, driving the drive shaft 107 to rotate, which in turn causes the active bevel gear 108 to rotate. The meshing of the active bevel gear 108 and the linkage bevel gear 105 causes the connecting column 103 and its top support frame 109 to rotate accordingly. This rotational action ensures that the detection mechanism 2, mounted on the support frame 109, can detect hazardous materials from different directions, greatly improving detection efficiency and coverage.

[0041] The dual-axis motor 301 serves as the power source, and its bottom output shaft drives the drive screw 302 to rotate. Simultaneously, through the connection of the coupling and the rotating rod 401, it drives the connecting screw 303 to rotate synchronously. The threads on the drive screw 302 and the connecting screw 303 engage with the threaded holes of the moving plate 304, causing the moving plate 304 to move vertically under the rotation of the screw. This movement drives the synchronous movement of the first thermal imager 305, realizing infrared thermal imaging scanning of the detection area.

[0042] Meanwhile, the rotating roller 402 at the top of the rotating rod 401 is connected to the linkage roller 309 at the top of the linkage screw 306 via a belt, so that the linkage screw 306 can rotate synchronously while driving the screw 302 to rotate. The lifting plate 307 moves vertically under the action of the thread of the linkage screw 306, thereby driving the second thermal imager 308 to move up and down. This design realizes the synchronous movement of the first thermal imager 305 and the second thermal imager 308 in the vertical direction, which greatly improves the flexibility and accuracy of thermal imaging scanning.

[0043] During the thermal imaging scan, the exploration component 5 begins to operate. Upon receiving a command, the electric push rod 502 extends, pushing the movable block 503 and the gas detector 504 on its front forward. The wedge-shaped structure of the movable block 503 allows for gas concentration detection in areas suspected of containing hazardous materials when the movable block 503 and the gas detector 504 are extended, while simultaneously compressing the combination structure of the telescopic rod 505 and the spring 507. After the detection is completed, the electric push rod 502 shortens, causing the movable block 503 to move backward. The previously compressed telescopic rod 505 and spring 507 return to their original shape, allowing the connecting frame 506 to cover the front of the movable block 503, protecting the gas detector 504.

[0044] During the inspection process, the photovoltaic panel 113 continuously charges the battery 114, ensuring the power supply for the drone equipment during long-term operation. When suspected hazardous materials are detected, the infrared features captured by the thermal imager and the gas concentration data detected by the gas detector 504 will be comprehensively analyzed to accurately determine the type and storage location of the hazardous materials.

[0045] 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, the scope of which is defined by the appended claims and their equivalents.
