Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle capable of throwing a life buoy. Background Technique

[0002] Due to the complexity, variability, suddenness and timeliness of water rescue, rescue activities are very urgent. However, since rescue forces often cannot understand the situation in time and arrive at the scene quickly, observing and intervening in the rescue from the air is currently the fastest and most convenient means.

[0003] For example, in Chinese Patent CN204979242U, through a unique throwing mechanism, the structure is simple, the weight is light, the load capacity is saved, the motor load is reduced, the power is saved, the hovering time is extended, and multiple independent throws can be realized, greatly reducing the time-consuming of going back and forth and the waste of multiple throws.

[0004] Although the above patent can make multiple independent throws, greatly reducing the time-consuming of going back and forth and the waste of multiple throws, it cannot accurately throw the life buoy during the operation process, so that the life buoy will be moved by external factors (wind, water flow, etc.) during the throwing process, reducing the utilization rate of the life buoy. Therefore, an unmanned aerial vehicle capable of throwing a life buoy is provided, so that when the life buoy is put into use, the life buoy will not deviate from the position of the drowning person due to external factors, improving the accuracy of throwing the life buoy. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an unmanned aerial vehicle capable of throwing a life buoy, which solves the problem that the life buoy will be moved by external factors (wind, water flow, etc.) during the throwing process.

[0006] To achieve the above purpose, the utility model is realized through the following technical solutions: an unmanned aerial vehicle capable of throwing a life buoy, including an unmanned aerial vehicle body, a throwing mechanism is fixedly connected to the bottom of the unmanned aerial vehicle body, support frames are fixedly connected to both the left and right sides of the bottom of the unmanned aerial vehicle body and located on both sides of the throwing mechanism, and a clamping mechanism is fixedly connected to the bottom of the throwing mechanism.

[0007] The utility model is further set as follows: the throwing mechanism includes a throwing frame, a motor is fixedly connected to the bottom of the throwing frame, an output shaft of the motor penetrates and extends to the top of the cross plate of the throwing frame, a driving gear is fixedly connected to the outside of the output shaft of the motor and above the cross plate of the throwing frame, a first long hole is opened around the driving gear at the top of the throwing frame, and a rotating rod is rotatably connected to the inside of the first long hole through a first bearing, a driven gear is fixedly connected to the outside of the rotating rod, a storage frame is fixedly connected to the outside of the rotating rod and above the driven gear, an adjusting frame is fixedly connected to the top of the throwing frame, and a storage rope is wound around the outside of the storage frame.

[0008] A second long strip hole is provided at the top of the adjusting frame and above the rotating rod, and the inside of the second long strip hole is rotationally connected to the outside of the rotating rod through a second bearing. A micro electric telescopic rod is fixedly connected to the top of the adjusting frame and on one side of the second long strip hole. The telescopic end of the micro electric telescopic rod is fixedly connected to the outside of the second bearing through a fixing block.

[0009] Guide rings are fixedly connected to the left and right sides of the front and rear parts of the placing frame, and one end of the receiving rope passes through the guide ring. The top of the docking frame is fixedly connected to one end of the receiving rope.

[0010] By adopting the above technical solution, the motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the rotating storage rack through the rotating rod, so that the receiving rope inside the storage rack moves the lifting plate downward to the drowning person through the docking frame.

[0011] The present utility model is further arranged as follows: The clamping mechanism includes a lifting plate. The top of the lifting plate is fixedly connected with a clamping telescopic rod through a fixing block. The telescopic end of the clamping telescopic rod is fixedly connected with a limiting plate. The periphery of the bottom of the lifting plate is rotationally connected with clamping plates through rotating blocks. The top of the clamping plate and near one side of the clamping telescopic rod is rotationally connected with a guiding rod through a rotating block. A guiding hole is provided at the top of the lifting plate and on the guiding rod. The top of the guiding rod passes through the guiding hole and is rotationally connected with the outside of the limiting plate through a rotating block.

[0012] A positioning groove is provided on the top of the clamping plate away from the clamping telescopic rod.

[0013] The top of the lifting plate is fixedly connected with a docking frame, and the clamping telescopic rod is arranged inside the docking frame.

[0014] By adopting the above technical solution, the clamping telescopic rod is contracted. The telescopic end of the clamping telescopic rod moves the guiding rod upward inside the guiding hole through the limiting plate, so that the clamping plate rotates and the life buoy is placed and falls on the water surface.

[0015] Beneficial effects

[0016] The utility model provides a drone capable of throwing a life buoy. Compared with the existing technology, the following beneficial effects are achieved:

[0017] (1) The drone for a throwable life buoy moves the drone body above the drowning person and hovers above the water surface. It contracts the micro electric telescopic rod. The micro electric telescopic rod drives the rotating rod along the first long hole and the second long hole towards the driving gear through the second bearing, so that the driving gear meshes with the driven gear. The motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate, and the driven gear drives the rotating storage rack through the rotating rod, so that the storage rope inside the storage rack moves the lifting plate towards the drowning person through the docking frame. In this way, when the life buoy is being dropped, the direction of the life buoy can be guided by the storage rope, so that the life buoy will not deviate from the position of the drowning person due to external factors, improving the accuracy of the life buoy drop.

[0018] (2) For the drone of the throwable life buoy, when the lifting plate moves close to the water surface, it contracts the clamping telescopic rod. The telescopic end of the clamping telescopic rod moves the guiding rod upward inside the guiding hole through the limiting plate, causing the clamping plate to rotate and dropping the life buoy onto the water surface. In this way, due to the weight of the clamping mechanism itself, the interference of external factors on the clamping mechanism during the dropping process of the life buoy can be reduced. Also, by contracting the clamping telescopic rod, the life buoy can be quickly released, improving the practicability of the drone for throwing the life buoy. Brief Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: an unmanned aerial vehicle with a throwable life buoy, including an unmanned aerial vehicle body 1, a throwing mechanism 2 is fixedly connected to the bottom of the unmanned aerial vehicle body 1, and support frames 3 are fixedly connected to both the left and right sides of the bottom of the unmanned aerial vehicle body 1 and located at the bottom of the throwing mechanism 2, and a clamping mechanism 4 is fixedly connected to the bottom of the throwing mechanism 2.

[0026] The bottom of the support frame 3 is lower than the bottom of the clamping mechanism 4.

[0027] As a preferred solution, as Figures 2-3 , the throwing mechanism 2 includes a throwing frame 5, a motor 6 is fixedly connected to the bottom of the throwing frame 5, the model of the motor 6 is SL57S2, the motor 6 is electrically connected to a rechargeable battery (not shown in the figure) and is controlled by a control switch. The output shaft of the motor 6 penetrates and extends to the top of the cross plate of the throwing frame 5. A driving gear 7 is fixedly connected to the outside of the output shaft of the motor 6 and above the cross plate of the throwing frame 5. First long holes are opened around the driving gear 7 at the top of the throwing frame 5, and a rotating rod 8 is rotatably connected to the inside of the first long holes through a first bearing. A driven gear 9 is fixedly connected to the outside of the rotating rod 8, a storage frame 10 is fixedly connected to the outside of the rotating rod 8 and above the driven gear 9, an adjusting frame 11 is fixedly connected to the top of the throwing frame 5, and a storage rope is wound around the outside of the storage frame 10.

[0028] Furthermore, a second long hole is opened at the top of the adjusting frame 11 and above the rotating rod 8, and the inside of the second long hole is rotatably connected to the outside of the rotating rod 8 through a second bearing. A micro electric telescopic rod 12 is fixedly connected to one side of the second long hole at the top of the adjusting frame 11, and the telescopic end of the micro electric telescopic rod 12 is fixedly connected to the outside of the second bearing through a fixing block.

[0029] Further, by moving the UAV body 1 above the drowning person and hovering above the water surface, the micro electric telescopic rod 12 is contracted. The model of the micro electric telescopic rod 12 is NKLA43. The micro electric telescopic rod 12 is electrically connected to a rechargeable battery (not shown in the figure) and is controlled by a control switch. The micro electric telescopic rod 12 drives the rotating rod 8 along the first long hole and the second long hole towards the driving gear 7 through the second bearing, so that the driving gear 7 is meshed and connected with the driven gear 9. The motor 6 drives the driving gear 7 to rotate, the driving gear 7 drives the driven gear 9 to rotate, and the driven gear 9 drives the rotating storage rack 10 through the rotating rod 8, so that the storage rope inside the storage rack 10 moves the lifting plate 13 towards the drowning person through the docking frame 18. In this way, when the life buoy is launched, the direction of the life buoy can be guided by the storage rope, so that the life buoy will not deviate from the position of the drowning person due to external factors, and the accuracy of the life buoy launch can be improved.

[0030] Further, guiding rings are fixedly connected to the left and right sides of the front and rear parts of the launching frame 5, and one end of the storage rope passes through the guiding rings. The top of the docking frame 18 is fixedly connected to one end of the storage rope.

[0031] As a preferred solution, as Figure 4 , the clamping mechanism 4 includes a lifting plate 13. The top of the lifting plate 13 is fixedly connected with a clamping telescopic rod 14 through a fixing block. The model of the clamping telescopic rod 14 is ANT-26. The clamping telescopic rod 14 is electrically connected to an external power supply and is controlled by a control switch. The telescopic end of the clamping telescopic rod 14 is fixedly connected with a limiting plate 15. The four sides of the bottom of the lifting plate 13 are rotatably connected with clamping plates 16 through rotating blocks. The top of the clamping plate 16 and on one side close to the clamping telescopic rod 14 are rotatably connected with a guiding rod 17 through a rotating block. A guiding hole is opened at the top of the lifting plate 13 and on the guiding rod 17. The top of the guiding rod 17 passes through the guiding hole and is rotatably connected with the outside of the limiting plate 15 through a rotating block.

[0032] Further, a docking frame 18 is fixedly connected to the top of the lifting plate 13, and the clamping telescopic rod 14 is arranged inside the docking frame 18.

[0033] Further, when the lifting plate 13 approaches the water surface, the clamping telescopic rod 14 is contracted. The telescopic end of the clamping telescopic rod 14 moves the guiding rod 17 upward inside the guiding hole through the limiting plate 15, so that the clamping plate 16 rotates, and the life buoy is launched and falls on the water surface. In this way, the weight of the clamping mechanism 4 itself can reduce the interference of external factors on the clamping mechanism 4 during the launch of the life buoy. By contracting the clamping telescopic rod 14, the life buoy can be quickly released, improving the practicability of the UAV for throwing the life buoy.

[0034] Meanwhile, the content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0035] When in use, first, the clamping telescopic rod 14 is contracted through the control switch. The telescopic end of the clamping telescopic rod 14 moves the guiding rod 17 upward inside the guiding hole through the limiting plate 15, causing the clamping plate 16 to rotate. Place the life buoy below the lifting plate 13, extend the clamping telescopic rod 14, and the telescopic end of the clamping telescopic rod 14 rotates the clamping plate 16 through the limiting plate 15 and the guiding rod 17, so that the clamping plate 16 clamps the life buoy below the lifting plate 13;

[0036] By controlling the movement of the UAV body 1, move the UAV body 1 above the drowning person and hover above the water surface. Contract the micro electric telescopic rod 12 through the control switch. The micro electric telescopic rod 12 drives the rotating rod 8 to move along the first long hole and the second long hole towards the driving gear 7 through the second bearing, so that the driving gear 7 is meshed and connected with the driven gear 9. Start the motor 6, the motor 6 drives the driving gear 7 to rotate, the driving gear 7 drives the driven gear 9 to rotate, and the driven gear 9 drives the storage rack 10 to rotate through the rotating rod 8, so that the storage rack 10 relaxes the storage rope inside. The relaxed storage rope drives the lifting plate 13 to move towards the drowning person below under the influence of the gravity of the docking rack 18;

[0037] When the lifting plate 13 approaches the water surface, contract the clamping telescopic rod 14. The telescopic end of the clamping telescopic rod 14 moves the guiding rod 17 upward inside the guiding hole through the limiting plate 15, causing the clamping plate 16 to rotate, and drop the life buoy onto the water surface.
