Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) equipment technology, specifically to a UAV equipment for recovering crashed UAVs. Background Technology

[0002] With the widespread application of drone technology, drones are increasingly used in aerial photography, logistics, surveying, rescue, and other fields. However, drone crashes occur frequently due to equipment malfunctions, signal interference, power system failures, and other reasons. When drones crash in areas that are difficult for people to reach or pose safety hazards, such as treetops, rooftops, cliffs, lakes, and dense forests, traditional manual recovery methods face numerous challenges.

[0003] Patent application CN202110113360.2 discloses a drone device for recovering crashed drones, including a carrying shell with a receiving cavity inside. The receiving cavity contains a receiving mechanism. A fixed track with front-to-back symmetry is fixedly installed at the lower end of the carrying shell at the rear end of the receiving cavity. A long slider slides left and right on the fixed track, and a rack is fixedly installed at the upper end of the long slider. This device can help people recover drones that have crashed in dangerous areas such as treetops, rooftops, and cliffs that are difficult for people to reach, without requiring personnel to venture out to search. It facilitates accurate and quick recovery of drone wreckage and internal storage devices. After recovery, there is no need to manually flip the device to remove the drone wreckage; the wreckage can be automatically removed for easy access. It has a high degree of integration.

[0004] Existing drone recovery equipment has limitations in dealing with underwater crash scenarios. When the target crashes in a deep water environment, the equipment cannot be directly recovered due to the lack of amphibious operation capabilities. It is often necessary to replace it with a dedicated underwater drone or supporting equipment. This operation mode increases the operating cost and time cost. When facing diverse scenarios such as lakes, deep seas, and complex underwater terrain, it is impossible to meet the needs of drone recovery with full terrain coverage. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a drone device for recovering crashed drones, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drone device for recovering a crashed drone, comprising a shell, a main controller fixedly connected to the top of the shell, a waterproof camera fixedly connected to the front end of the shell, a telescopic claw fixedly connected to the bottom of the shell, an adjustment mechanism movably connected to the inner wall of the shell, a locking mechanism fixedly connected to the inner wall of the shell, and a power mechanism rotatably connected to the bottom of the shell via a bearing.

[0007] The power mechanism includes:

[0008] The second outer shell is rotatably connected to the first outer shell via a bearing at its top. A circular plate is fixedly connected to the top of the second outer shell, and an extension plate is fixedly connected to the outer wall of the circular plate. A slider is fixedly connected to the top of the extension plate. A deflection assembly is rotatably connected to the inner wall of the second outer shell via a bearing. When the adjustment mechanism moves, it changes the overall deflection angle of the power mechanism. By setting up the power mechanism, the propeller deflection can be adjusted. The two sets of propellers on the rear side can deflect laterally to both sides of the fuselage and maintain a backward water-pushing posture, while the two sets of propellers on the front side can deflect forward and to a working state perpendicular to the fuselage. This layout enables the UAV to move forward, backward, and turn horizontally in an underwater environment, solving the problem of insufficient underwater maneuverability of traditional equipment and providing stable and reliable power support for recovery operations in complex water environments.

[0009] According to the above technical solution, a water storage tank is fixedly connected to the inner wall of the outer shell, a slot is opened at the bottom of the water storage tank, and a water pusher is movably connected to the inner wall of the water storage tank, so that external water can enter the interior of the water storage tank through the slot.

[0010] According to the above technical solution, a push rod is fixedly connected to the inner wall of the outer shell, and a connecting rod is fixedly connected to the front end of the push rod. The connecting rod passes through the water storage tank and extends to the inner wall of the water storage tank. The end of the connecting rod away from the push rod is fixedly connected to the push plate. The push rod is used to control the movement of the push plate. By setting up a water storage tank, when the push plate moves under the drive of the push rod, the bottom slot of the water storage tank opens, and external water is sucked into the tank through the fluid channel. By changing the amount of water in the tank, the buoyancy of the UAV can be adjusted, allowing the equipment to adjust its own depth in different water depth environments. With the real-time monitoring of the waterproof camera, it can sink to the target depth to perform recovery operations by sucking in water, and float up by discharging the water in the tank. Thus, it maintains a stable operating posture during underwater detection and recovery, effectively solving the problem of insufficient underwater depth control capability of traditional equipment.

[0011] According to the above technical solution, the adjustment mechanism includes a U-shaped plate, the top of which is movably connected to the outer shell, a sliding groove is provided on the inner wall of the U-shaped plate, a right-angle plate is fixedly connected to the bottom of the U-shaped plate, and a sliding groove is provided at the end of the right-angle plate away from the U-shaped plate. The inner wall of the sliding groove is movably connected to the slider. When the U-shaped plate moves, it can drive the power mechanism to deflect.

[0012] According to the above technical solution, a through hole is provided at the top of the circular plate, the through hole penetrates the circular plate and extends to the inner wall of the outer shell. A protruding plate is fixedly connected to the outer wall of the circular plate, and a locking hole is provided on the outer wall of the protruding plate. An auxiliary component is movably connected to the inner wall of the locking hole. The locking hole is used to lock the deflection angle of the power mechanism with the cooperation of the auxiliary component.

[0013] According to the above technical solution, the locking mechanism includes a push rod two, the outer wall of the push rod two is fixedly connected to the outer shell one, the top of the push rod two is fixedly connected to a connecting plate one, and both ends of the connecting plate one are fixedly connected to a locking rod one. The outer wall of the locking rod one is movably connected to the through hole. The push rod two can control the height of the locking rod one. By setting the locking mechanism, the push rod two drives the connecting plate one to move the locking rod one up and down. Not only can the locking state of the auxiliary component be controlled by the pressure plate, but also the longitudinal deflection angle of the propeller can be locked by the engagement of the locking rod one with the locking hole two on the hollow column. This effectively suppresses the axial vibration and radial displacement of the propeller when it is running at high speed, and improves the operating stability of the power mechanism.

[0014] According to the above technical solution, a connecting plate 2 is fixedly connected to the outer wall of the connecting plate 1, an extension plate 1 is fixedly connected to the outer wall of the connecting plate 1, the end of the extension plate 1 away from the connecting plate 1 is fixedly connected to the connecting plate 2, a pressure plate is fixedly connected to the bottom of the extension plate 1, and the height of the pressure plate can change the state of the auxiliary component.

[0015] According to the above technical solution, the top of the connecting plate 2 is provided with a sliding groove 3, the inner wall of the sliding groove 3 is fixedly connected with a push rod 3, the inner wall of the sliding groove 3 is movably connected with a movable plate, the outer wall of the movable plate is fixedly connected with the push rod 3, the outer wall of the movable plate is fixedly connected with a slider 1, the outer wall of the slider 1 is movably connected with the connecting plate 1, and the push rod 3 can control the forward and backward movement of the adjustment mechanism.

[0016] According to the above technical solution, the auxiliary component includes a base plate, the bottom of which is fixedly connected to the outer shell, and a hollow plate fixedly connected to the top of the base plate. A locking rod 2 is movably connected to the inner wall of the hollow plate, and the outer wall of the locking rod 2 is movably connected to a locking hole 1. A connector is fixedly connected to the end of the locking rod 2 away from the locking hole 1, and a connecting plate 3 is rotatably connected to the inner wall of the connector via a bearing. A slide rail is fixedly connected to the top of the base plate, and a slider 3 is movably connected to the inner wall of the slide rail. The inner wall of the slider 3 is rotatably connected to the connecting plate 3 via a bearing. An elastic component is fixedly connected to the bottom of the slider 3, and the outer wall of the elastic component is fixedly connected to the base plate. When the slider 3 is squeezed by the pressure plate, the locking rod 2 moves outward. By setting the auxiliary component, after the propeller completes the lateral deflection adjustment, the slider 3 slides along the slide rail under the squeezing action of the pressure plate, driving the connecting plate 3 to drive the locking rod 2 to move outward through the connector and embed into the locking hole 1 of the protruding plate, thus avoiding the risk of loosening of the power mechanism due to propeller vibration.

[0017] According to the above technical solution, the deflection assembly includes a waterproof motor, the outer wall of the housing is fixedly connected to the waterproof motor, the inner wall of the housing is rotatably connected to a hollow column via a bearing, the output end of the waterproof motor is fixedly connected to the hollow column, the outer wall of the hollow column is provided with a locking hole, so the inner wall of the locking hole is movably connected to a locking rod, a connecting rod is fixedly connected to the end of the locking hole away from the waterproof motor, the end of the connecting rod away from the locking hole is fixedly connected to the waterproof motor, the output end of the waterproof motor is fixedly connected to a propeller, and the waterproof motor can control the deflection angle of the propeller.

[0018] Compared with the prior art, the present invention provides a drone device for recovering a crashed drone, which has the following beneficial effects:

[0019] 1. This invention achieves propeller deflection adjustment by setting up a power mechanism. The two rear propellers can be deflected laterally to both sides of the fuselage and maintain a backward water-pushing posture, while the two front propellers can be deflected forward and to a working state perpendicular to the fuselage. This layout enables the UAV to move forward, backward, and turn horizontally in the underwater environment, solving the problem of insufficient underwater maneuverability of traditional equipment and providing stable and reliable power support for recovery operations in complex water environments.

[0020] 2. This invention features a water storage tank. When the pusher plate moves under the drive of the pusher rod, the bottom opening of the water storage tank opens, allowing external water to be drawn into the tank through a fluid channel. By changing the amount of water inside the tank, the buoyancy of the UAV can be adjusted, enabling the device to adjust its depth in different water environments. Combined with real-time monitoring by a waterproof camera, the device can both sink to the target depth to perform recovery operations by drawing in water and float up by discharging water from the tank. This maintains a stable operating posture during underwater exploration and recovery, effectively solving the problem of insufficient underwater depth control capability of traditional equipment.

[0021] 3. By setting up an auxiliary component, after the propeller completes the lateral deflection adjustment, the slider three slides along the slide rail under the squeezing action of the pressure plate, which drives the connecting plate three to move outward through the connecting head and drive the locking rod two to embed into the locking hole one of the protruding plate, thus avoiding the risk of loosening of the power mechanism caused by propeller vibration.

[0022] 4. By setting a locking mechanism, the push rod two drives the connecting plate one to move the locking rod one up and down. Not only can the locking state of the auxiliary components be controlled by the pressure plate, but the locking rod one can also lock the longitudinal deflection angle of the propeller by engaging with the locking hole two on the hollow column. This effectively suppresses axial vibration and radial displacement of the propeller when it is running at high speed, and improves the operational stability of the power mechanism.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0038] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] Example 1: See Figures 1-4 This invention provides a technical solution: a drone device for recovering a crashed drone, comprising a shell 1, a main control unit 101 fixedly connected to the top of the shell 1, a water tank 105 provided to facilitate the drone's floating in water, a waterproof camera 102 fixedly connected to the front end of the shell 1, a telescopic claw 104 fixedly connected to the bottom of the shell 1, an adjustment mechanism 2 movably connected to the inner wall of the shell 1, a locking mechanism 3 fixedly connected to the inner wall of the shell 1, a power mechanism 4 rotatably connected to the bottom of the shell 1 via a bearing, and a water tank 105 fixedly connected to the inner wall of the shell 1. A slot 103 is provided at the bottom of the water tank 105, and a water-pushing plate 108 is movably connected to the inner wall of the water tank 105, allowing external water to enter the interior of the water tank 105 through the slot 103. A push rod 106 is fixedly connected to the inner wall of the outer shell 1. A connecting rod 107 is fixedly connected to the front end of the push rod 106. The connecting rod 107 passes through the water storage tank 105 and extends to the inner wall of the water storage tank 105. The end of the connecting rod 107 away from the push rod 106 is fixedly connected to the push plate 108. When the device detects that the falling drone has fallen into the water, it first keeps the drone floating on the water surface. Then, it adjusts the angle of the power mechanism 4. After the power mechanism 4 completes the attitude adjustment, it drives the push rod 106 to drive the connecting rod 107 to move, thereby pulling the push plate 108 to move horizontally towards the inside of the water storage tank. During this process, the external water is sucked into the water storage tank 105 under the action of pressure difference. By changing the water volume in the tank, the buoyancy state of the drone is changed, and finally the drone is controlled to sink.

[0040] Example 2: Please refer to Figures 5-7Based on Embodiment 1, the present invention provides a technical solution: In order to facilitate the lateral angle adjustment and locking of the power mechanism 4 of the UAV, an adjustment mechanism 2 and a locking mechanism 3 are provided. The adjustment mechanism 2 includes a U-shaped plate 201, the top of which is movably connected to the outer shell 1. A groove 202 is provided on the inner wall of the U-shaped plate 201. A right-angle plate 204 is fixedly connected to the bottom of the U-shaped plate 201. A groove 203 is provided at the end of the right-angle plate 204 away from the U-shaped plate 201. The inner wall of the groove 203 is movably connected to the slider 404. When the U-shaped plate 201 moves, it can drive the power mechanism 4 to deflect.

[0041] The locking mechanism 3 includes a second push rod 301, the outer wall of which is fixedly connected to the outer shell 1. A connecting plate 302 is fixedly connected to the top of the second push rod 301. Locking rods 303 are fixedly connected to both ends of the connecting plate 302. The outer wall of the locking rods 303 is movably connected to the through hole 405. The second push rod 301 can control the height of the locking rods 303. A second connecting plate 306 is fixedly connected to the outer wall of the connecting plate 302. An extension plate 304 is connected, with one end of the extension plate 304 away from the connecting plate 302 fixedly connected to a connecting plate 306. A pressure plate 305 is fixedly connected to the bottom of the extension plate 304, and the height of the pressure plate 305 can change the state of the auxiliary component 41. A slide groove 309 is provided on the top of the connecting plate 306, and a push rod 307 is fixedly connected to the inner wall of the slide groove 309. A movable plate 308 is movably connected to the inner wall of the slide groove 309. The wall is fixedly connected to the push rod 307. The outer wall of the movable plate 308 is fixedly connected to the slider 3010. The outer wall of the slider 3010 is movably connected to the connecting plate 302. When the lateral angle of the power mechanism 4 needs to be adjusted, the push rod 301 is first activated to drive the connecting plate 302 to move upward, thereby releasing the lock on the power mechanism 4. At the same time, the connecting plate 302 drives the extension plate 304 to move upward, causing the pressure plate 305 to disengage from the auxiliary component 41, thus unlocking the auxiliary component 41. Then, the push rod 307 is activated, and the movable plate 308 pulls the slider 3010 to move, thereby moving the U-shaped plate 201. The translation of the U-shaped plate 201 acts on the slider 404 of the power mechanism 4 through the groove 203 of the right-angle plate 204, thereby achieving the lateral angle deflection of the power mechanism 4. After the angle adjustment is completed, the push rod 301 reverses its action to drive the connecting plate 302 to reset, thus relocking the power mechanism 4.

[0042] Example 3: Please refer to Figures 8-11Based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: In order to facilitate longitudinal angle adjustment and locking of propeller 426, a power mechanism 4 is provided. The power mechanism 4 includes: a second outer shell 401, the top of which is rotatably connected to the first outer shell 1 via a bearing, a circular plate 402 fixedly connected to the top of the second outer shell 401, an extension plate 403 fixedly connected to the outer wall of the circular plate 402, a slider 404 fixedly connected to the top of the extension plate 403, and a deflection assembly 42 rotatably connected to the inner wall of the second outer shell 401 via a bearing. When the adjustment mechanism 2 moves, the overall deflection angle of the power mechanism 4 is changed. A through hole 405 is provided at the top of the circular plate 402. The through hole 405 passes through the circular plate 402 and extends to the inner wall of the outer shell 401. A protruding plate 406 is fixedly connected to the outer wall of the circular plate 402. A locking hole 407 is provided on the outer wall of the protruding plate 406. An auxiliary component 41 is movably connected to the inner wall of the locking hole 407. The locking hole 407 is used to lock the deflection angle of the power mechanism 4 with the cooperation of the auxiliary component 41.

[0043] Auxiliary component 41 includes a base plate 411, the bottom of which is fixedly connected to the outer casing 1. A hollow plate 412 is fixedly connected to the top of the base plate 411. A locking rod 413 is movably connected to the inner wall of the hollow plate 412. The outer wall of the locking rod 413 is movably connected to a locking hole 407. A connector 414 is fixedly connected to the end of the locking rod 413 away from the locking hole 407. A connecting plate 415 is rotatably connected to the inner wall of the connector 414 via a bearing. A slide rail 418 is fixedly connected to the top of the base plate 411. A slider 3 416 is movably connected to the inner wall of component 8. The inner wall of slider 3 416 is rotatably connected to connecting plate 3 415 via bearings. An elastic component 417 is fixedly connected to the bottom of slider 3 416. The outer wall of elastic component 417 is fixedly connected to base plate 411. When pressure plate 305 presses slider 3 416 downward, slider 3 416 moves along slide rail 418. Through connecting plate 3 415 and connector 414, locking rod 2 413 moves forward and engages in locking hole 1 407, thus locking the deflection angle of power mechanism 4. When pressure plate 305 moves upward, slider 3 416 is released from pressure constraint. The restoring force of elastic component 417 drives slider 3 416 to move upward along slide rail. Through the traction of connecting plate 3 415 and connector 414, locking rod 2 413 is pulled out of locking hole 1 407, completing the unlocking action of power mechanism 4.

[0044] The deflection assembly 42 includes a waterproof motor 421. The outer wall of the housing 401 is fixedly connected to the waterproof motor 421. A hollow column 422 is rotatably connected to the inner wall of the housing 401 via a bearing. The output end of the waterproof motor 421 is fixedly connected to the hollow column 422. A locking hole 423 is provided on the outer wall of the hollow column 422, so the inner wall of the locking hole 423 is movably connected to the locking rod 303. A connecting rod 424 is fixedly connected to the end of the locking hole 423 away from the waterproof motor 421. The end of the connecting rod 424 away from the locking hole 423 is fixedly connected to... A waterproof motor 425 is connected, and a propeller 426 is fixedly connected to the output end of the waterproof motor 425. When the longitudinal angle of the propeller 426 needs to be adjusted, the connecting plate 302 is first driven to move upward by the push rod 301, so that the locking rod 303 disengages from the locking hole 423 of the hollow column 422, thereby releasing the lock on the deflection component 42. Then, the waterproof motor 421 is started to drive the hollow column 422 to rotate. The rotation of the hollow column 422 is transmitted to the waterproof motor 425 through the connecting rod 424, thereby realizing the adjustment of the longitudinal deflection angle of the propeller 426. After the angle adjustment is completed, the push rod 301 reverses its movement to drive the locking rod 303 to re-embed into the locking hole 423, thus positioning the deflection component 42.

[0045] The amphibious propulsion system is the core of the application to realize cross-scenario recovery of "air flight-underwater operation". The amphibious propulsion system uses four sets of propulsion mechanisms 4 with "two in front and two in the back" symmetrically distributed as the execution end. The adjustment mechanism 2 realizes the lateral angle deflection, the deflection component 42 realizes the longitudinal angle deflection, and then the locking mechanism 3 and the auxiliary component 41 form "two-level locking" to suppress vibration, and finally output the power adapted to air and underwater scenarios.

[0046] Detailed description of the control process:

[0047] Power direction adjustment: Lateral deflection is driven by adjustment mechanism 2. The extension and retraction of push rod 307 in locking mechanism 3 drives movable plate 308 to slide along slide groove 309. Movable plate 308 pulls U-shaped plate 201 to move back and forth through slider 3010. The slide groove 203 of right angle plate 204 at the bottom of U-shaped plate 201 forms a sliding engagement with slider 404 of power mechanism 4. Under the pull of slider 404, power mechanism 4 rotates around the bearing connected to outer shell 1 to achieve lateral angle deflection. Longitudinal deflection is completed by deflection component 42. Waterproof motor 421 drives hollow column 422 to rotate around the bearing on the inner wall of outer shell 401. Hollow column 422 drives waterproof motor 425 and propeller 426 to rotate synchronously through connecting rod 424, adjusting the longitudinal angle of propeller to form a power layout suitable for underwater forward, backward and turning.

[0048] Attitude stabilization control: A two-stage locking system is adopted. The first-stage locking is achieved by the locking mechanism 3. The extension of the push rod 301 causes the connecting plate 302 to descend. The locking rods 303 at both ends of the connecting plate 302 pass through the through hole 405 of the power mechanism 4 and are inserted into the locking hole 423 of the hollow column 422. The second-stage locking relies on the auxiliary component 41. When the connecting plate 302 descends, the extension plate 304 drives the pressure plate 305 to squeeze the slider 416. The slider 416 slides along the slide rail 418 and compresses the elastic component 417. At the same time, the connecting plate 415 and the connector 414 push the locking rod 413 to slide along the hollow plate 412 and insert it into the locking hole 407 of the protruding plate 406. This second-stage locking, by fitting and fixing the lateral position of the power mechanism 4 and the longitudinal angle of the deflection component 42, suppresses axial vibration and radial offset, and prevents the propeller vibration from causing loosening.

[0049] Power output: Both waterproof motor 421 and waterproof motor 425 adopt a fully sealed structure to ensure underwater operation. Waterproof motor 425 drives propeller 426 to rotate. Underwater, it provides power by pushing water, and in the air, it deflects the propeller to a vertical upward attitude to push air to achieve lift-off. It is suitable for amphibious scenarios and meets the needs of the entire recovery operation.
