Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) monitoring technology, and specifically relates to a forest fire monitoring UAV. Background Technology

[0002] Forests, as the core of terrestrial ecosystems, are crucial for maintaining ecological balance and promoting socio-economic development. However, forest fires are characterized by their sudden onset and rapid spread, easily causing significant ecological and economic losses. Therefore, efficient and accurate fire monitoring has become key to disaster prevention and mitigation. Against this backdrop, drones, with their advantages of mobility, wide monitoring range, and real-time capabilities, have gradually developed into core equipment in forest fire monitoring systems.

[0003] Forest fire situations are often dynamic, so in the same monitoring task, it is often necessary to switch between different sized cameras according to day and night and environmental conditions. For example, small visible light cameras can be used for routine patrols during the day, while large thermal imaging cameras need to be used at night to achieve continuous and effective fire monitoring.

[0004] Currently, most drone-based fire monitoring gimbals suffer from limited compatibility. Their mounting slots and fixing structures are designed for cameras of specific sizes (such as visible light or thermal imaging cameras), making it impossible to flexibly install cameras of different sizes. This significantly limits the overall applicability and mission flexibility of fire monitoring drones. Utility Model Content

[0005] In view of the common problem of limited adaptability of drone fire monitoring gimbals, this utility model proposes a forest fire monitoring drone to overcome the above-mentioned technical problems existing in related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a forest fire monitoring drone, including a drone, a gimbal assembly at the bottom of the drone, a mounting frame inside the gimbal assembly, two sets of elastic clamping assemblies symmetrically arranged inside the mounting frame, a compression limiting assembly on the upper side of the elastic clamping assembly, and a locking assembly between the elastic clamping assembly and the compression limiting assembly. By sliding the camera into the mounting frame, the two sets of elastic clamping components clamp the camera on both sides. By driving the squeezing end of the squeezing limiting component, the squeezing end squeezes the camera downward, while the locking component locks the position of the elastic clamping components.

[0007] Furthermore, the gimbal assembly includes a mounting frame, which is fixedly mounted on the bottom of the drone. A first gimbal motor is fixedly mounted inside the mounting frame, and a rotating frame is fixedly connected to the output end of the first gimbal motor. The mounting frame is rotatably connected inside the rotating frame, and a second gimbal motor is fixedly mounted on one side of the rotating frame. The output end of the second gimbal motor is fixedly connected to the mounting frame.

[0008] Furthermore, the elastic clamping assembly includes a T-shaped compression rod, which is movably connected to the mounting frame. One end of the T-shaped compression rod is fixedly connected to a clamping plate, and the other end of the T-shaped compression rod is fixedly connected to a compression spring between its protruding position and the outer side of the mounting frame. One end of the clamping plate expands outward, and a shielding cylinder is fixedly installed on the outer side of the mounting frame corresponding to the T-shaped compression rod.

[0009] Furthermore, a rotating groove is provided on the inner side of the clamping plate and the bottom of the inner wall of the mounting frame, and a rotating roller is rotatably connected inside the rotating groove.

[0010] Furthermore, the extrusion limiting assembly includes an inverted C-shaped extrusion frame disposed inside the mounting frame. An extrusion screw is rotatably connected to the top of the inverted C-shaped extrusion frame, and the extrusion screw is threadedly connected to the mounting frame. A guide rod is fixedly connected to the top of the inverted C-shaped extrusion frame, and the guide rod is movably connected to the mounting frame.

[0011] Furthermore, a limiting plate is movably connected inside the C-shaped extrusion frame, and an adjusting screw is rotatably connected to the back of the limiting plate. The adjusting screw is threadedly connected to the C-shaped extrusion frame, and a control disc is fixedly connected to one end of both the extrusion screw and the adjusting screw.

[0012] Furthermore, the locking assembly includes a fixing plate, which is fixedly connected to the inner wall of the mounting frame. The fixing plate has multiple T-shaped pressing rods corresponding to the T-shaped pressing rods. A T-shaped pushing rod is movably connected to one side of the fixing plate. One end of the T-shaped pushing rod passes through the fixing plate and is fixedly connected to an L-shaped locking rod. A limit rod is fixedly connected to one side of the L-shaped locking rod. The limit rod is movably connected to the fixing plate. A return spring is provided between the protruding part of the other end of the T-shaped pushing rod and the fixing plate. Pressing columns are fixedly installed on both sides of the U-shaped pressing frame corresponding to the T-shaped pushing rods. Pressing blocks are fixedly connected to the bottom of the pressing columns. The bottom sides of the pressing blocks are inclined.

[0013] This utility model has the following beneficial effects: This invention moves the camera directly into the mounting frame, allowing the elastic clamping components to clamp the camera on both sides. Then, it directly drives the compression limiting component, causing the compression end to press downwards against the camera between the two elastic clamping components. In this configuration, the distance between the two elastic clamping components and the distance between the compression end and the bottom of the inner wall of the mounting frame can be adjusted, allowing the monitoring drone to clamp and fix cameras of different specifications. This also improves the overall applicability and mission flexibility of the monitoring drone.

[0014] When the extrusion screw is rotated, the C-shaped extrusion frame can drive the extrusion block to move downward through the extrusion column. At this time, the extrusion block can push the L-shaped locking rod through the inclined surface, thereby causing the L-shaped locking rod to move towards the T-shaped extrusion rod. When the extrusion block is completely moved between the two L-shaped locking rods, the two L-shaped locking rods can squeeze the T-shaped extrusion rod, thereby locking the T-shaped extrusion rod. The above configuration allows the flexible clamping of the two clamping plates on the left and right sides of the camera to be converted into rigid clamping when the camera is clamped upward, thereby significantly enhancing the overall stability of the installed camera. At the same time, the entire operation only requires rotating the extrusion screw, making the operation relatively convenient.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0020] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0021] Please see Figures 1-7 As shown, this utility model is a forest fire monitoring drone, including a drone 1. A gimbal assembly 2 is provided at the bottom of the drone 1. An installation frame 3 is provided inside the gimbal assembly 2. Two sets of elastic clamping assemblies 4 are symmetrically arranged inside the installation frame 3. A compression limiting assembly 5 is provided on the upper side of the elastic clamping assembly 4. A locking assembly 6 is provided between the elastic clamping assembly 4 and the compression limiting assembly 5. By sliding the camera into the interior of the mounting frame 3, the two sets of elastic clamping components 4 clamp the camera on both sides. By driving the squeezing end of the squeezing limiting component 5, the squeezing end squeezes the camera downward. At the same time, the locking component 6 locks the position of the elastic clamping component 4.

[0022] When installing the camera inside the mounting frame 3, the camera is directly pushed into the mounting frame 3. At this time, the two sets of elastic clamping components 4 can clamp the two sides of the camera. After the camera moves to the predetermined position, the squeezing limit component 5 is driven, so that the squeezing end of the squeezing limit component 5 moves downward and squeezes the camera. At the same time, the locking component 6 can lock the position of the elastic clamping component 4 under the action of the squeezing end.

[0023] By moving the camera directly into the mounting frame 3, the elastic clamping components 4 clamp the camera on both sides. Then, the compression limiting component 5 is driven directly, causing the compression end to press down on the camera between the two elastic clamping components 4. In the above configuration, since the distance between the two elastic clamping components 4 and the distance between the compression end and the bottom of the inner wall of the mounting frame 3 can be adjusted, the monitoring drone can clamp and fix cameras of different specifications, which also improves the overall applicability and mission flexibility of the monitoring drone.

[0024] In one embodiment, the gimbal assembly 2 includes a mounting frame 201, which is fixedly mounted on the bottom of the drone 1. A first gimbal motor 202 is fixedly mounted inside the mounting frame 201. The output end of the first gimbal motor 202 is fixedly connected to a rotating frame 203. The mounting frame 3 is rotatably connected inside the rotating frame 203. A second gimbal motor 204 is fixedly mounted on one side of the rotating frame 203. The output end of the second gimbal motor 204 is fixedly connected to the mounting frame 3.

[0025] The first gimbal motor 202 can drive the rotating frame 203 to rotate left and right, and the second gimbal motor 204 can drive the mounting frame 3 to rotate up and down inside the rotating frame 203. With the assistance of the two gimbal motors, the mounting frame 3 can rotate at a large angle at the bottom of the drone, so that the camera inside the mounting frame 3 can better monitor the forest fire.

[0026] In one embodiment, the elastic clamping assembly 4 includes a T-shaped compression rod 401, which is movably connected to the mounting frame 3. One end of the T-shaped compression rod 401 is fixedly connected to a clamping plate 402, and the other end of the T-shaped compression rod 401 is fixedly connected to the outer side of the mounting frame 3 with a compression spring 403. One end of the clamping plate 402 expands outward, and a shielding cylinder 404 is fixedly installed on the outer side of the mounting frame 3 corresponding to the T-shaped compression rod 401.

[0027] When installing the camera, place it on the bottom of the inner wall of the mounting frame 3 and push it. The moving camera pushes the clamping plate 402 at an angle. As the camera moves, the two clamping plates 402 can move to the sides. Simultaneously, the T-shaped compression rod 401 moves on the mounting frame 3 under the push of the clamping plate 402, pulling the compression spring 403. When the camera reaches the predetermined position, stop pushing it. At this point, the compression spring 403, through its force on the T-shaped compression rod... The compression rod 401 is pulled, allowing the clamping plate 402 to clamp the camera. In the above configuration, under the pull of the compression spring 403, the two clamping plates 402 can clamp cameras of various sizes. At the same time, the shape of the clamping plate 402 makes it easy to move the camera between the two clamping plates 402 by simply pushing it. The shielding cylinder 404 can shield the compression spring 403, thereby preventing the compression spring 403 from being damaged by external factors.

[0028] In one embodiment, for the clamping plate 402, a rotating groove 405 is provided on the inner side of the clamping plate 402 and the bottom of the inner wall of the mounting frame 3, and a rotating roller 406 is rotatably connected inside the rotating groove 405.

[0029] The clamping plate 402 and the rotating roller 406 on the mounting frame 3 can come into contact with the camera. As the camera moves, the rotating roller 406 can rotate inside the corresponding rotating groove 405. This arrangement makes it less likely that the surface of the camera will be damaged by friction when the camera is pushed between the two clamping plates 402.

[0030] In one embodiment, the extrusion limiting component 5 includes an inverted U-shaped extrusion frame 501 disposed inside the mounting frame 3. An extrusion screw 502 is rotatably connected to the top of the inverted U-shaped extrusion frame 501 and is threadedly connected to the mounting frame 3. A guide rod 503 is fixedly connected to the top of the inverted U-shaped extrusion frame 501 and is movably connected to the mounting frame 3.

[0031] Once the camera is in the appropriate position, the extrusion screw 502 is rotated, allowing the U-shaped extrusion frame 501 to move downwards under the push of the extrusion screw 502 and the guidance of the guide rod 503. When the U-shaped extrusion frame 501 contacts the top of the camera, the rotation of the extrusion screw 502 stops. This arrangement allows the U-shaped extrusion frame 501 and the mounting frame 3 to clamp the upper and lower sides of the camera, thereby further improving the camera's stability.

[0032] In one embodiment, for the above-mentioned C-shaped extrusion frame 501, a limiting plate 504 is movably connected inside the C-shaped extrusion frame 501, and an adjusting screw 505 is rotatably connected to the back of the limiting plate 504. The adjusting screw 505 is threadedly connected to the C-shaped extrusion frame 501, and a control disk 506 is fixedly connected to one end of both the extrusion screw 502 and the adjusting screw 505.

[0033] The bottom of the limiting plate 504 is located below the C-shaped extrusion frame 501. When the camera, which is moving between the two clamping plates 402, comes into contact with the limiting plate 504, the C-shaped extrusion frame 501 is moved downwards and comes into contact with the top of the camera. The adjusting screw 505 is moved directly, so that the limiting plate 504 moves forward towards the camera under the push of the adjusting screw 505 and the guidance of the C-shaped extrusion frame 501. When the front of the camera comes into contact with the inner wall of the C-shaped extrusion frame 501, the rotation of the adjusting screw 505 stops. At this time, the limiting plate 504 and the C-shaped extrusion frame 501 can clamp the front and rear sides of the camera.

[0034] In one embodiment, the locking component 6 includes a fixing plate 601, which is fixedly connected to the inner wall of the mounting frame 3. The fixing plate 601 has multiple T-shaped pressing rods 401. A T-shaped pushing rod 602 is movably connected to one side of the fixing plate 601. One end of the T-shaped pushing rod 602 passes through the fixing plate 601 and is fixedly connected to an L-shaped locking rod 603. A limiting rod 604 is fixedly connected to one side of the L-shaped locking rod 603. The limiting rod 604 is movably connected to the fixing plate 601. A return spring 605 is provided between the protruding end of the T-shaped pushing rod 602 and the fixing plate 601. Pressing columns 606 are fixedly installed on both sides of the U-shaped pressing frame 501 corresponding to the T-shaped pushing rods 602. A pressing block 607 is fixedly connected to the bottom of the pressing column 606, and the bottom sides of the pressing block 607 are inclined.

[0035] When the C-shaped extrusion frame 501 moves downward, the two extrusion columns 606 can move downward synchronously. At this time, the extrusion block 607 at the bottom of the extrusion column 606 can push the L-shaped locking rod 603 through the inclined surface, so that the L-shaped locking rod 603 moves under the guidance of the T-shaped push rod 602 and the limit rod 604. At the same time, the L-shaped locking rod 603 pulls the return spring 605. When the extrusion block 607 moves completely between the two L-shaped locking rods 603, the two L-shaped locking rods 603 can squeeze the T-shaped extrusion rod 401. At this time, the friction between the L-shaped locking rod 603 and the T-shaped extrusion rod 401 is relatively large. This ensures that the T-shaped extrusion rod 401 is less likely to shift due to the shaking of the drone, while also guaranteeing the clamping effect of the clamping plate 402. When the extrusion block 607 has completely moved between the two L-shaped locking rods 603, before the C-shaped extrusion frame 501 has made contact with the camera, the C-shaped extrusion frame 501 can continue to be pushed downwards. At this time, the extrusion block 607 and the extrusion column 606 can move synchronously between the two L-shaped locking rods 603, so that the L-shaped locking rods 603 can always keep the T-shaped extrusion rod 401 locked, and the whole process only requires the extrusion screw 502 to be rotated.

[0036] Through the above technical solution, 1. By moving the camera directly into the mounting frame 3, the elastic clamping component 4 clamps the two sides of the camera, directly driving the extrusion limiting component 5, thereby causing the extrusion end to press downwards against the camera between the two elastic clamping components 4; in the above setting, since the distance between the two elastic clamping components 4 and the distance between the extrusion end and the bottom of the inner wall of the mounting frame 3 can be adjusted, the monitoring drone can clamp and fix cameras of different specifications, and at the same time improve the overall applicability and mission flexibility of the monitoring drone; 2. When the extrusion screw 502 is rotated, the U-shaped extrusion frame 501 can be driven by the extrusion column 606. The pressing block 607 moves downward. At this time, the pressing block 607 can push the L-shaped locking rod 603 through the inclined surface, so that the L-shaped locking rod 603 moves towards the T-shaped pressing rod 401. When the pressing block 607 is completely moved between the two L-shaped locking rods 603, the two L-shaped locking rods 603 can press the T-shaped pressing rod 401, thereby locking the T-shaped pressing rod 401. The above setting allows the flexible clamping of the two clamping plates 402 on the left and right sides of the camera to be converted into rigid clamping when clamping the camera upward, thereby significantly enhancing the overall stability of the installed camera. At the same time, the whole operation only requires rotating the pressing screw 502, which is also relatively convenient.
