[0002] When natural disasters such as earthquakes occur, traditional search and rescue methods mainly rely on manpower, search and rescue dogs, and audio life detectors. However, in actual applications, these methods have problems such as low search and rescue efficiency, great terrain restrictions, and susceptibility to secondary disasters.

[0003] In order to solve the above problems, technicians innovatively combined drones with radar life detectors, using drones carrying radar life detectors to conduct mobile searches to detect trapped people. However, this combination still faces a significant problem in practical applications: the radar life detector is fixedly installed under the drone, which causes its detection direction to be mainly limited to vertically downward. If the detection angle needs to be adjusted, the drone must be controlled to change its flight attitude accordingly, which undoubtedly increases the difficulty and complexity of drone operation and affects the convenience of use.

Through this innovative design, the present invention not only overcomes the problem of limited detection angle in the traditional combination, but also further enhances the practicality and efficiency of the combination of the UAV body and the radar life detector.

The controller is equipped with a built-in wireless communication module, which establishes a stable and reliable communication link with the external remote control handle, thereby realizing remote control of the entire drone life detection equipment and real-time data transmission.

[0007] In addition, the drone life detection device proposed in the application may also have the following additional technical features: The control rod frame is symmetrically fixedly connected to the outer surface of the U-shaped bracket and is located on the inner side of the adjusting column, and the end of the adjusting column and the end of the adjusting column are slidably connected to the inner wall of the adjusting column.

[0008] Specifically, the two groups of one-way transmissions have the same structure, and the transmission directions of the two groups of one-way transmissions are opposite.

[0009] Specifically, the adjusting vertical cylinder includes an upper cylinder, a middle cylinder and a lower cylinder, and the upper cylinder, middle cylinder and lower cylinder are arranged in sequence from top to bottom in the vertical direction. The upper cylinder is threadedly connected to the outer surface of the first reciprocating screw rod, and are respectively slidably connected to the connecting column rod and the outer surface of the frame body. The middle cylinder is located on one side of the bottom of the frame body, and is respectively rotatably connected to the bottom of the upper cylinder and the top of the lower cylinder. The lower cylinder is vertically slidably connected to the inner wall of the frame. The bottom of the lower cylinder is integrally formed with an annular platform, and the inner wall of the annular platform is provided with an annular guide groove.

[0010] Specifically, the direction adjustment rod frame includes a fixed cylinder seat, a bent rod and a sphere. The fixed cylinder seat is fixedly connected to the outer surface of one end of the U-shaped bracket, one end of the bent rod is fixedly connected to the surface of the fixed cylinder seat, and the other end is fixedly connected to the sphere.

[0014] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The structure of the present invention is reasonable. The present invention can flexibly adjust the detection angle of the radar life detector body and the camera angle of the camera under the premise that the drone maintains the original flight posture. This feature greatly reduces the complexity and difficulty of the operation process, making the use experience smoother, and also significantly improves the overall use effect. Through this innovative design, the present invention not only overcomes the problem of limited detection angle in the traditional combination, but also further enhances the practicality and efficiency of the combination of the drone body and the radar life detector; 2. The present invention cleverly sets the camera directly on the radar life detector body. This design has the following advantages. The first is synchronous range coverage. By setting the camera directly on the radar life detector body, it is ensured that the visual capture range of the camera is highly synchronized with the detection range of the radar life detector. This means that whether it is a search and rescue operation or monitoring life signs, the operator can obtain a video image that matches the radar detection result, so as to understand the detection result more intuitively. The second is the consistency of angle adjustment. When the operator adjusts the detection angle of the radar life detector, the camera will also adjust its camera angle accordingly, ensuring that the camera and detection angles are always consistent. This design greatly simplifies the operation process, improves work efficiency, and also ensures the accuracy of data collection. The third is the optimization of the use effect. Due to the consistency of the camera and detection angles, the operator can interpret the information detected by the radar more accurately and efficiently, and make quick and accurate judgments in combination with the real-time video images. This is crucial for application scenarios such as emergency rescue and disaster assessment. In addition, this design also reduces false alarms or missed alarms caused by mismatches between devices, further improving the overall use effect. 3. The present invention innovatively sets up a detection adjustment component. The detection adjustment component design proposed in the present invention has brought revolutionary changes to the angle adjustment of the radar life detector and the camera. The component works together through a series of precise mechanical structures to achieve precise control of the detector body and the camera in the horizontal and vertical directions. Its specific advantages are as follows: the first is the precise adjustment capability: the detection adjustment component integrates key components such as a dual-axis motor, a first reciprocating screw, a rotating seat, a one-way transmission, an adjustment vertical cylinder, a U-shaped bracket and a direction adjustment rod frame. Under the joint action of these components, the radar life detector body and the camera can be finely adjusted, and a high degree of accuracy and stability can be achieved in both the horizontal and vertical directions. The second is the reduction in operating difficulty: traditionally, changing the detection angle and the camera angle often requires adjusting the flight attitude or manually rotating the device, which is not only complicated to operate, but also easy to introduce errors. The adjustment mechanism of the present invention achieves automatic adjustment through mechanical transmission, which significantly reduces the operating difficulty and makes it easier for operators It can focus more on the detection task itself. The third is to flexibly adapt to different needs and environments: the design of the adjustment mechanism fully considers the diversity in practical applications. Whether it is a complex urban environment, a small space or severe weather conditions, the detection equipment can adapt to different detection needs and environmental conditions through a flexible adjustment mechanism. This flexibility not only improves the accuracy and efficiency of detection, but also greatly expands the scope of application of the equipment. The fourth is the improvement of the detection effect: due to the ability to achieve precise angle adjustment and flexible adaptability, the detection equipment of the present invention has been significantly improved in detection effect. Whether it is looking for trapped people, monitoring signs of life or conducting disaster assessments, it can provide more accurate and reliable data support, and provide a more powerful basis for relevant decisions. The design of the detection adjustment component not only improves the adjustment accuracy and flexibility of the radar life detector and the camera, but also significantly reduces the difficulty of operation, improves the detection effect and practicality, and this design is of great significance to improving the work efficiency and accuracy in emergency rescue, disaster assessment and other fields; 4. The present invention incorporates a combination of a frame, a protective plate and a drawer plate in its design. This innovative protective structure provides comprehensive and effective protection for the radar life detector body and its camera, which is specifically reflected in the following aspects: First, comprehensive protection: the frame, as the basis of the entire protective structure, cooperates with the protective plate and the drawer plate to provide a solid shell for the radar life detector body and the camera. This shell can effectively resist external physical impacts, thereby ensuring the normal operation of the detector and the camera. Second, convenient maintenance: the design of the drawer plate takes into account the maintenance needs of the equipment. Through the protective plate and the drawer plate, the operator can easily perform necessary maintenance on the radar life detector body and the camera inside the frame. Cleaning, inspection and maintenance work, this design not only improves the maintainability of the equipment, but also reduces the maintenance cost. The third is to extend the service life: due to the joint protection of the frame, protective plate and drawer, the radar life detector body and camera can be protected from erosion and damage by the external environment, thereby significantly extending their service life. This is of great significance for improving the reliability and stability of the equipment, and also saves users the cost of replacing equipment. The frame, protective plate and drawer design not only improves the durability and reliability of the equipment, but also reduces the maintenance cost and use cost. It is of great significance to improve the work efficiency and accuracy in the fields of emergency rescue and disaster assessment, and also provides new ideas for the protection design of related equipment; 5. The present invention innovatively provides a side defense linkage component, which realizes the intelligent linkage between the detection and adjustment component and the protective door, which not only meets the convenience requirements of the radar life detector body when adjusting the angle, but also ensures that the protective performance of the equipment is not affected. The following are several major advantages of this component: First, intelligent linkage: the side defense linkage component can monitor the working status of the detection and adjustment component in real time. Once the detector body starts to adjust the angle, the linkage component can respond quickly and automatically adjust the opening or closing state of the corresponding protective door. This intelligent linkage mechanism greatly simplifies the operation process and improves work efficiency; second, convenient use: when the detector body is adjusting the angle, the automatic opening of the protective door provides the operator with an unobstructed field of view and operating space, making the adjustment process smoother. After the adjustment is completed, the protective door can automatically close to restore the protective state of the equipment, ensuring the safety and stability of the equipment; third That is, protection performance guarantee: the design of the side protection linkage component fully considers the protection performance requirements. When the protection door is open, it can ensure that the key parts of the detector body and the camera will not be exposed, avoiding damage caused by accidental collisions or environmental factors. At the same time, when the protection door is closed, it can provide a tight sealing effect to prevent the invasion of harmful substances such as dust and moisture; Fourth, strong adaptability: the side protection linkage component can adapt to the adjustment needs of different angles and directions. During horizontal adjustment, the linkage component can accurately judge the opening or closing time of the protective door to ensure that the equipment can maintain a good protection state at any angle. The side protection linkage component not only realizes the intelligent linkage between the detection adjustment component and the protective door, improves the convenience and protection performance of the equipment, but also provides new ideas and directions for equipment design in related fields. This design is of great significance to improving work efficiency and accuracy in fields such as emergency rescue and disaster assessment. BRIEF DESCRIPTION OF THE DRAWINGS

On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0019] A drone life detection device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0020] like Figure 1-Figure 10As shown, a drone life detection device according to an embodiment of the present invention comprises: a drone body 1: as the main structure of the whole system, responsible for executing flight missions, equipped with necessary flight control systems and power systems; a detection device 2: comprising a frame 21, a detection adjustment component 22 and a side protection linkage component 23, the frame 21 is fixedly connected to the landing gear 11 in the drone body 1 by tightening the handle 12, the lower end surface of the frame 21 is evenly provided with through grooves 212, the upper end surface of the frame 21 is evenly slidably connected with a protective plate 211 and is located outside the through groove 212, the inner wall of the bottom plate in the frame 21 is slidably connected with a drawer plate 213, the detection adjustment component 22 is arranged on the inner wall of the frame 21, the side protection linkage component 23 is arranged on the detection adjustment component 22, and is respectively connected with multiple groups of protective plates 211; a radar life detector body 3: It is fixedly installed at the bottom of the detection and adjustment component 22, and uses radar wave technology to penetrate obstacles, detect and identify weak movement signals of living organisms, and effectively locate potential trapped persons; the camera 4 is directly installed on the radar life detector body 3, and has infrared thermal imaging, night vision and wide-angle shooting capabilities, which are used to capture on-site images in real time and provide intuitive visual information for rescue command; the drone body 1, the detection and adjustment component 22, the radar life detector body 3 and the camera 4 are all seamlessly connected to the controller 14 built into the drone body 1 through the bus system, ensuring rapid data transmission and accurate reception of control commands. The controller 14 has a built-in wireless communication module 15, which establishes a stable and reliable communication link with the external remote control handle 16, thereby realizing remote control of the entire drone life detection equipment and real-time data transmission.

[0021] It should be noted that the built-in power supply 13 of the drone body 1 described in this embodiment provides power for the drone body 1 , the detection and adjustment component 22 , the radar life detector body 3 and the camera 4 .

[0022] It should also be noted that the drawer plate 213 described in this embodiment is fixed to the inner wall of the bottom plate in the frame body 21 by magnetic attraction.

[0023] It can be understood that, in the initial state, one set of protective plates 211 is in an open state and corresponds to the detection angle of the radar life detector body 3 and the shooting angle of the camera 4, and the other three sets of protective plates 211 and the drawer 213 are in a closed state.

[0024] Specifically, the present invention can flexibly adjust the detection angle of the radar life detector body 3 and the camera 4 under the premise that the drone maintains the original flight posture unchanged. This feature greatly reduces the complexity and difficulty of the operation process, makes the use experience smoother, and also significantly improves the overall use effect. Through this innovative design, the present invention not only overcomes the problem of limited detection angle in the traditional combination, but also further enhances the practicality and efficiency of the combination of the drone body 1 and the radar life detector body 3. Its working principle is as follows: when in use, first pull out the drawer plate 213 from the inside of the bottom plate to facilitate the radar life detector body 3 and the camera 4 to detect and shoot downward, then control the drone body 1 to take off through the external remote control handle 16, and bring the radar life detector body 3 and the camera 4 to the set detection area. In the initial state, one group of protective plates 211 is in an open state (that is, the corresponding through slot 212 is not blocked), the radar life detector body 3 and the camera 4 are both in a vertical state, and the detection angle and the camera angle are both facing the protective plate 211, and the other three groups of protective plates 211 are in In the closed state, when the horizontal angle of the radar life detector body 3 and the camera 4 needs to be adjusted, the external remote control handle 16 and the wireless communication module 15 cooperate with each other to send a command to the controller 14. After receiving the command, the controller 14 drives the detection adjustment component 22 to operate, and the dual-axis motor 222 in the detection adjustment component 22 rotates forward to link the radar life detector body 3 and the camera 4 to rotate horizontally, so as to achieve horizontal adjustment. During the rotation of the radar life detector body 3 and the camera 4, the detection adjustment component 22 and the side defense linkage component 23 are used to adjust the horizontal angle of the radar life detector body 3 and the camera 4. They cooperate with each other and synchronously drive the protective plate 211 corresponding to the angle of the radar life detector body 3 and the camera 4 to open and synchronously close the protective plate 211 that does not correspond to the angle of the radar life detector body 3 and the camera 4. The reversal of the dual-axis motor 222 in the detection and adjustment component 22 links the radar life detector body 3 and the camera 4 to rotate in the vertical direction, so that they change from a vertical state to a horizontal state, thereby realizing vertical adjustment. When the radar life detector body 3 and the camera 4 are in a horizontal state, their bottoms are facing downward, so that they can detect and photograph the bottom, and the use effect is good.

[0025] In one embodiment of the present invention, Figure 3-Figure 8As shown, the detection adjustment assembly 22 includes a frame 221, a double-axis motor 222, a first reciprocating screw rod 223, a rotating seat 224, a one-way transmission 225, an adjustment vertical cylinder 226, a U-shaped bracket 227 and a direction adjustment rod frame 228. The frame 221 is fixedly connected to the top wall of the frame 21 through the connecting column 100, the double-axis motor 222 is fixedly connected to the inner wall of the frame 221, the first reciprocating screw rod 223 and the rotating seat 224 are respectively rotatably connected to the top of the frame 221 and the bottom of the frame 221, and one end of the first reciprocating screw rod 223 and one end of the rotating seat 224 are connected to the double-axis motor 221 through the one-way transmission 225. 22 output ends are connected, one end of the first reciprocating screw rod 223 away from the one-way transmission device 225 is rotatably connected to the top wall of the frame 21, the adjusting vertical cylinder 226 is threadedly connected to the outer surface of the first reciprocating screw rod 223, and is slidably connected to the outer surface of the connecting column 100 and the frame body 221 respectively, the U-shaped bracket 227 is rotatably connected to the outer surface of the end of the rotating seat 224 away from the one-way transmission device 225, the adjusting rod frame 228 is symmetrically fixedly connected to the outer surface of the U-shaped bracket 227, and is located on the inner side of the adjusting vertical cylinder 226, and the end of the adjusting rod frame 228 away from the U-shaped bracket 227 is slidably connected to the inner wall of the adjusting vertical cylinder 226.

[0026] It should be noted that an encoder is disposed on the surface of the dual-axis motor 222 described in this embodiment. The encoder is used to detect the number of rotations of the dual-axis motor 222 in real time. The encoder is connected to the controller 14 via a bus system.

[0027] Specifically, the detection and adjustment component 22 is a complex and powerful mechanical structure, which is designed to flexibly adjust the angle and range of the radar life detector body 3 and the camera 4. Among them, the frame 221 is the supporting structure of the entire detection and adjustment component 22, and is fixedly connected to the inner top wall of the frame 21 through the connecting column 100. It provides an installation basis for the dual-axis motor 222, the first reciprocating screw rod 223, the rotating seat 224 and the one-way transmission 225. The dual-axis motor 222 is fixedly connected to the inner wall of the frame 221 and is the power source for driving the entire detection and adjustment component 22 to move. It has two output ends, which are respectively connected to the first reciprocating screw rod 223 and the rotating seat 224 through the one-way transmission 225 to achieve different motion controls. The first reciprocating screw rod 223 is rotatably connected to the top of the frame body 221, and one end of the first reciprocating screw rod 223 is connected to an output end of the double-axis motor 222 through a one-way transmission 225. When the double-axis motor 222 rotates in the opposite direction, the first reciprocating screw rod 223 can be driven to rotate through the one-way transmission 225, thereby driving the adjustment vertical cylinder 226 to reciprocate on the first reciprocating screw rod 223 to achieve vertical adjustment. The rotating seat 224 is rotatably connected to the bottom of the frame body 221, and one end of the first reciprocating screw rod 223 is also connected to the other output end of the double-axis motor 222 through the one-way transmission 225. When the double-axis motor 222 rotates forward, the rotating seat 224 is driven to rotate through the one-way transmission 225, and the rotating seat 224 rotates synchronously to drive the U-shaped bracket 227 and the adjustment rod bracket 228 The one-way transmission device 225 is used to realize the one-way transmission between the output end of the dual-axis motor 222 and the first reciprocating screw rod 223 and the rotating seat 224, so as to ensure that their movements can be controlled separately when needed. The adjusting vertical cylinder 226 is threadedly connected to the outer surface of the first reciprocating screw rod 223, and is slidably connected to the outer surface of the connecting column rod 100 and the frame body 221 respectively. When the first reciprocating screw rod 223 rotates, the adjusting vertical cylinder 226 will reciprocate on the first reciprocating screw rod 223, thereby synchronously driving the adjustment rod frame 228 and the U-shaped bracket 227 to move in the vertical direction. The U-shaped bracket 227 is rotatably connected to the outer surface of one end of the rotating seat 224 away from the one-way transmission device 225. The adjustment rod frame 228 is provided with an installation foundation and is allowed to rotate in the vertical direction with the rotating seat 224 as the center. The adjustment rod frame 228 is symmetrically fixedly connected to the outer surface of the U-shaped bracket 227 and is located on the inner side of the adjustment vertical cylinder 226. One end of the adjustment rod frame 228 is slidably connected to the inner wall of the adjustment vertical cylinder 226. When the adjustment vertical cylinder 226 moves in the vertical direction or the U-shaped bracket 227 rotates in the horizontal direction, the adjustment rod frame 228 will move or rotate accordingly, thereby realizing precise adjustment of the detection equipment. The detection adjustment component 22 realizes precise adjustment of the radar life detector body 3 and the camera 4 in the horizontal and vertical directions through the coordinated work of the dual-axis motor 222, the first reciprocating screw 223, the rotating seat 224, and the one-way transmission 225.This adjustment mechanism enables the detection equipment to flexibly adapt to different detection requirements and environmental conditions, improving the accuracy and efficiency of detection.

[0028] In one embodiment of the present invention, Figure 6 As shown, the two groups of one-way transmission devices 225 have the same structure, and the transmission directions of the two groups of one-way transmission devices 225 are opposite.

[0029] It should be noted that the one-way transmission 225 described in this embodiment is a ratchet one-way transmission.

[0030] Specifically, the two groups of one-way transmissions 225 are structurally consistent, which means that they have the same internal structure and working principle. This consistency helps to ensure the overall stability and reliability of the detection and adjustment assembly 22. The two groups of one-way transmissions 225 have opposite transmission directions. This design enables the dual-axis motor 222 to control the operation of the first reciprocating screw 223 and the rotating seat 224 respectively, thereby achieving more flexible and diverse adjustment methods. Among them, a power source design also correspondingly reduces production costs and has a good use effect.

[0031] In one embodiment of the present invention, Figure 4 and Figure 7 As shown, the adjusting vertical cylinder 226 includes an upper cylinder 2261, a middle cylinder 2262 and a lower cylinder 2263, and the upper cylinder 2261, the middle cylinder 2262 and the lower cylinder 2263 are arranged in sequence from top to bottom along the vertical direction. The upper cylinder 2261 is threadedly connected to the outer surface of the first reciprocating screw rod 223, and is respectively slidably connected to the connecting column rod 100 and the outer surface of the frame body 221. The middle cylinder 2262 is located on one side of the bottom of the frame body 221, and is respectively rotatably connected to the bottom of the upper cylinder 2261 and the top of the lower cylinder 2263. The lower cylinder 2263 is vertically slidably connected to the inner wall of the frame body 21, and an annular platform 22631 is integrally formed at the bottom of the lower cylinder 2263, and an annular guide groove 22632 is opened on the inner wall of the annular platform 22631.

[0032] Specifically, the structure and connection relationship of the adjusting vertical cylinder 226 are further explained. The adjusting vertical cylinder 226 realizes flexible adjustment and stability in the vertical direction through the ingenious combination and connection method of the upper cylinder 2261, the middle cylinder 2262 and the lower cylinder 2263. Among them, the threaded connection and sliding connection of the upper cylinder 2261, the rotation connection of the middle cylinder 2262, and the vertical sliding connection of the lower cylinder 2263 and the annular platform 22631 design together constitute a complex and effective adjustment mechanism of the vertical cylinder. This design not only improves the adjustment accuracy and flexibility of the adjusting vertical cylinder 226, but also ensures its stability and reliability in various complex environments.

[0033] In one embodiment of the present invention, Figure 8As shown, the adjustment rod frame 228 includes a fixed cylinder seat 2281, a bent rod 2282 and a sphere 2283. The fixed cylinder seat 2281 is fixedly connected to the outer surface of one end of the U-shaped bracket 227, one end of the bent rod 2282 is fixedly connected to the surface of the fixed cylinder seat 2281, and the other end is fixedly connected to the sphere 2283. The sphere 2283 is located inside the annular guide groove 22632 and is slidably connected to the inner wall of the annular guide groove 22632.

[0034] Specifically, the structure and connection relationship of the adjustment rod frame 228 are further described. The fixed cylinder seat 2281 is a stable foundation of the adjustment rod frame 228, which is responsible for fixing the entire adjustment rod frame 228 to the U-shaped bracket 227. The bent rod 2282 is a rod with a curved shape, which plays a role in connecting and transmitting force. The ball 2283 is a round ball 2283, which is located inside the annular guide groove 22632 and is slidably connected to the inner wall of the annular guide groove 22632. This sliding connection allows the ball 2283 to move freely in the annular guide groove 22632, thereby realizing the adjustment of the adjustment rod frame 228. The steering function is realized by the fixed connection between the steering rod frame 228 and the U-shaped bracket 227 through the fixed connection between the fixed cylinder seat 2281 and the U-shaped bracket 227, as well as the ingenious design of the bent rod 2282 and the sphere 2283, so as to realize the sliding steering function in the annular guide groove 22632. This design not only improves the stability and reliability of the structure, but also makes the steering process more flexible and smooth. When the sphere 2283 rises, it will synchronously drive the bent rod 2282 and the fixed cylinder seat 2281 to rotate. The rotation of the fixed cylinder seat 2281 synchronously drives the U-shaped bracket 227 to rotate, so as to realize the vertical angle adjustment of the radar life detector body 3 and the camera 4, and the use effect is good.

[0035] In one embodiment of the present invention, Figure 4 As shown, the side anti-linkage assembly 23 includes a driving toothed disc 231, a synchronous toothed disc 232, a passive gear 233 and a second reciprocating screw rod 234. The driving toothed disc 231 is fixedly connected to the outer surface of the middle cylinder 2262, the synchronous toothed disc 232 is fixedly connected to the outer surface of the rotating seat 224 and is located inside the middle cylinder 2262, and keyways and key blocks are respectively provided at positions corresponding to the positions of the surface of the synchronous toothed disc 232 and the inner wall of the middle cylinder 2262. The key block is vertically slidably connected to the inner wall of the keyway, the passive gear 233 is evenly rotated and connected to the inner wall of the frame 21, and is meshed with the teeth on the surface of the driving toothed disc 231, the second reciprocating screw rod 234 is evenly rotated and connected to the inner wall of the frame 21, and is fixedly connected to one end of the central axis of the passive gear 233, and one end of the protective plate 211 penetrates into the interior of the frame 21 and is threadedly connected to the outer surface of the second reciprocating screw rod 234.

[0036] It should be noted that the number of the passive gear 233 , the second reciprocating screw rod 234 and the protective plate 211 described in this embodiment is equal and their positions are corresponding.

[0037] It should also be noted that the height of the driving gear disc 231 is greater than the height of the passive gear 233 , and the passive gear 233 is also slidably connected to the driving gear disc 231 to facilitate height adjustment of the driving gear disc 231 .

[0038] Specifically, the structure and connection relationship of the side anti-linkage assembly 23 are further described. The driving toothed disc 231 is fixedly connected to the outer surface of the middle cylinder 2262, which means that when the middle cylinder 2262 rotates or moves, the driving toothed disc 231 will also rotate or move accordingly. The surface of the driving toothed disc 231 is provided with teeth, which are used to mesh with the passive gear 233 to transmit power. The synchronous toothed disc 232 is fixedly connected to the outer surface of the rotating seat 224 and is located inside the middle cylinder 2262. This positional relationship ensures synchronization. The relative position of the step toothed disc 232 and the middle cylinder 2262 is stable. The surface of the synchronous toothed disc 232 and the inner wall of the middle cylinder 2262 are respectively provided with a keyway and a key block. The key block is vertically slidably connected to the inner wall of the keyway. This design is convenient for power transmission and height adjustment, and has strong stability. The passive gear 233 is evenly rotated and connected to the inner wall of the frame 21, and is meshed with the teeth on the surface of the driving toothed disc 231. This meshing connection enables the driven gear 233 to rotate when the driving toothed disc 231 rotates. The passive gear 233 acts as an intermediary for power transmission, and transmits the rotational power of the driving gear plate 231 to the second reciprocating screw rod 234. The second reciprocating screw rod 234 is evenly connected to the inner wall of the frame 21 and is fixedly connected to one end of the central axis of the passive gear 233. This connection enables the second reciprocating screw rod 234 to rotate when the passive gear 233 rotates. One end of the protective plate 211 penetrates into the interior of the frame 21 and is threadedly connected to the outer surface of the second reciprocating screw rod 234. This threaded connection is connected to the second reciprocating screw rod 23 When rotating, the protective plate 211 can be driven to reciprocate on the outer surface of the frame 21. The reciprocating movement of the protective plate 211 realizes the opening and closing of the corresponding through slot 212, and the use effect is better. The side protection linkage component 23 realizes the reciprocating movement and adjustment function of the protective plate 211 through the coordinated work of the driving gear plate 231, the synchronous gear plate 232, the passive gear 233 and the second reciprocating screw rod 234. This design not only improves the stability and reliability of the entire system, but also makes the adjustment of the protective plate 211 more flexible and convenient.

[0039] In one embodiment of the present invention, Figure 4 As shown, the driving toothed disc 231 is meshed and connected with two sets of passive gears 233 at the same time. Whenever the driving toothed disc 231 completes a meshing action with any passive gear 233, the action will trigger and drive the protective plate 211 to realize a single lifting operation.

[0040] Specifically, the driving gear plate 231 meshes with the two sets of passive gears 233 to achieve synchronous driving of the two sets of protective plates 211. Whenever the driving gear plate 231 completes the meshing with any passive gear 233, a single lifting operation of the protective plate 211 is triggered. This design ensures that when the first set of protective plates 211 is closed, the second set of protective plates 211 can be opened synchronously with the movement of the radar life detector body 3, ensuring that the detection direction of the detector and the camera 4 is unobstructed, which is convenient for data collection. At the same time, the closed protective plates 211 provide protection for the detector and the camera 4, reduce the risk of impact with foreign objects, and improve the use effect.

[0041] In one embodiment of the present invention, Figure 4 As shown, the height of the U-shaped bracket 227 is greater than the radius of the annular platform 22631 , and half of the length of the radar life detector body 3 is less than the height between the annular platform 22631 and the driving gear disc 231 .

[0042] Specifically, the height of the U-shaped bracket 227 is designed to be higher than the radius of the annular table 22631, ensuring that when the U-shaped bracket 227 is turned from a horizontal state to a vertical state, the radar life detector body 3 will not interfere with the annular table 22631, thereby enabling smooth adjustment. At the same time, the length of the radar life detector body 3 is set to be less than half of the height between the annular table 22631 and the driving gear disc 231. This design ensures that the instrument will not have a structural conflict with the driving gear disc 231 in a vertical state, thereby ensuring its smooth operation and excellent use effect.

[0043] In summary, a drone life detection device in an embodiment of the present invention can flexibly adjust the detection angle of the radar life detector body 3 and the shooting angle of the camera 4 under the premise that the drone maintains its original flight posture. This feature greatly reduces the complexity and difficulty of the operation process, making the use experience smoother, and also significantly improves the overall use effect. Through this innovative design, the present invention not only overcomes the problem of limited detection angle in the traditional combination, but also further enhances the practicality and efficiency of the combination of the drone body 1 and the radar life detector body 3.
