Description

Technical Field

[0001] The present invention belongs to the technical field of UAV throwing, and particularly relates to a continuous thrower. Background Art

[0002] The unmanned aerial vehicle, abbreviated as "UAV" and with the English abbreviation "UAV", is an unpiloted aircraft controlled by a radio remote control device and a self - contained program control device, or is completely or intermittently autonomously operated by an on - vehicle computer.

[0003] Compared with piloted aircraft, UAVs are often more suitable for tasks that are too "dull, dirty or dangerous". According to the application field, UAVs can be divided into military and civilian. In the military aspect, UAVs are divided into reconnaissance aircraft and target drones. In the civilian aspect, UAV + industry application is the real demand for UAVs; currently, applications in aerial photography, agriculture, plant protection, micro - self - shooting, express delivery, disaster relief, wildlife observation, monitoring of infectious diseases, mapping, news reporting, power inspection, disaster relief, film shooting, creating romance and other fields have greatly expanded the uses of UAVs themselves, and developed countries are also actively expanding industry applications and developing UAV technologies.

[0004] The thrower is a common airborne equipment in the application of UAV systems, mainly used to throw disaster relief materials / fire extinguishing bombs / lifebuoys, etc. With the wide application of UAVs in disaster relief, forest fire fighting and other fields, the thrower has received more and more attention. However, the existing throwers can generally only perform single - throw, and it is difficult to play a role in multi - point rescue in the rescue field; when multiple items are hung, these items are prone to entanglement due to the action of air flow and their own inertia in the air, resulting in the failure of distributed throwing.

[0005] Patent document CN201610860865 discloses a UAV continuous throwing device and a controller. The device includes an upper clamping plate and a lower clamping plate. The lower clamping plate is provided with a plurality of through - holes. A plurality of storage containers are arranged between the upper clamping plate and the lower clamping plate. The bottom end of the storage container is provided with an opening, and the opening is arranged opposite to the through - hole; on the side of the lower clamping plate away from the upper clamping plate, there is a rotating plate. The rotating plate is provided with a material leakage hole. The rotating plate is connected with a driving device. The driving device includes a servo motor. The servo motor is connected with a rotating shaft, and the rotating shaft is connected with the rotating plate. However, this patent can only throw objects with a relatively small volume. If it is necessary to throw objects with a larger volume, it cannot be achieved due to the weight of the thrower body.

[0006] Therefore, it is necessary to design a new UAV continuous thrower. Summary of the Invention

[0007] The object of the present invention is to provide a continuous thrower, so as to solve the problems proposed in the background art that existing throwers can generally only perform single throws and are difficult to play a role in multi-point rescue in the rescue field; when multiple items are hung, these items are prone to entanglement with each other due to the action of air flow and their own inertia in the air, resulting in the failure of distributed throwing.

[0008] To achieve the above object, the present invention provides a continuous thrower, which includes a servo motor, a servo motor connecting shaft, a one-way bearing, a suspension frame, a perforated lock shell, a vertical bracket, a sub-throwing disc and more than two suspension ropes;

[0009] The servo motor is connected to the inner ring of the one-way bearing through the servo motor connecting shaft, and the outer ring of the one-way bearing is fixedly connected to the suspension frame. The suspension frame includes a circular ring-shaped bracket with a notch and a radial support member. The radial support member is used to fixedly connect the circular ring-shaped bracket to the outer ring of the one-way bearing, so that the suspension frame can rotate unidirectionally under the action of the power provided by the servo motor and the control provided by the one-way bearing. The two sides of the notch are respectively the support end and the free end of the circular ring-shaped bracket;

[0010] The perforated lock shell contains more than two through holes for longitudinally passing through the suspension ropes, and the through holes are located below the circular ring-shaped bracket. A sub-throwing disc with more than two rope passing holes is arranged below the perforated lock shell. The perforated lock shell and the sub-throwing disc are directly or indirectly fixedly connected through a structure including a vertical bracket. The top of the suspension rope is hung on the circular ring-shaped bracket, and the suspension rope sequentially passes through the through holes and the rope passing holes downward, and the suspension rope below the sub-throwing disc is used to connect with the object to be thrown;

[0011] When the servo motor drives the suspension frame to rotate unidirectionally, the position of the suspension rope remains basically unchanged under the block of the hole wall at the peripheral position of the through hole. Therefore, when the suspension frame rotates, the suspension rope moves relative to the suspension frame. When the free end beside the notch of the suspension frame rotates above a certain through hole, the top of the suspension rope falls off from the free end and the notch on the circular ring-shaped bracket, and the object connected to the suspension rope is thrown downward due to the falling of the suspension rope.

[0012] In a specific embodiment, the vertical support includes a vertical connecting rod coaxially arranged with the servo connecting shaft and arranged below the servo connecting shaft, and the continuous thrower also includes a torque limiting device for keeping the suspension frame stationary and not rotating when there is no external power drive, the torque limiting device includes an inner ring and an outer ring, a certain friction force is maintained between the inner ring and the outer ring, and the inner ring of the torque limiting device is arranged below the one-way bearing, the inner ring of the torque limiting device is fixedly arranged on the outer periphery of the vertical connecting rod, and the outer ring thereof has an upper extension member extending upward in the height direction relative to the inner ring, and the upper extension member clamps and fixes the radial support member, and relies on the friction force between the inner ring and the outer ring of the torque limiting device to keep the suspension frame stationary and not rotating without external force drive.

[0013] In a specific embodiment, the continuous throwing device also includes a connecting and fixing sleeve for fixing the perforated lock shell and the vertical connecting rod, the vertical connecting rod is configured as a retractable structure, and the throwing plate is detachably connected to the vertical connecting rod.

[0014] In a specific embodiment, the continuous thrower is used on a drone, and the continuous thrower also includes a remote control receiving device arranged on a steering gear.

[0015] In a specific embodiment, the suspension bracket is configured to be a suspension bracket that can rotate unidirectionally clockwise or counterclockwise in a horizontal plane.

[0016] In a specific embodiment, the radial support member is a rod-shaped structure, and one end of the radial support member is fixedly connected to the support end.

[0017] In a specific embodiment, the top of the suspension rope is a rope loop type or a hook type, and the rope loop or hook is used to be hung on the circular bracket, and falls off from the notch on the circular bracket during casting; the aperture size of the rope hole is smaller than the size of the rope loop or hook, so that the rope loop or hook falls above the rope hole, so that the top of the suspension rope is hung on the casting plate and the suspension rope will not fall off the casting device.

[0018] In a specific embodiment, the multiple through holes provided on the perforated lock shell, the multiple rope holes provided on the dispensing disc, and the multiple hanging ropes are all arranged at uniform intervals in the circumferential direction, and the number of the through holes, rope holes, and hanging ropes is 3 to 30.

[0019] In a specific embodiment, the continuous thrower also includes a locking cover, which is arranged above the suspension frame and below the servo, and the servo connecting shaft passes through the locking cover, and the locking cover is detachably connected to the lock shell with a hole; the continuous thrower also includes a servo guard plate for protecting the servo, and the servo guard plate is fixedly connected to the locking cover.

[0022] The present invention can continuously throw the payloads, improving the efficiency and saving time. Due to the design of the sub-throwing disc, the multiple payloads of the present invention will not be entangled with each other due to the action of air flow and their own inertia in the air, and thus the problem of distributed throwing failure will not occur. The spindle and suspension rope with adjustable lengths and the sub-throwing discs of different sizes can flexibly handle payloads of different volumes, making the hanging more convenient.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following will elaborate on the embodiments of the present invention in detail with reference to the drawings, but the present invention can be implemented in various different ways defined and covered by the claims.

[0030] Embodiment 1

[0031] A continuous throwing device provided by the present invention, the continuous throwing device includes a steering gear 1, a steering gear connecting shaft 2, a one-way bearing 3, a suspension bracket 5, a perforated lock housing 6, a vertical bracket 8, a sub-throwing disc 9 and more than two suspension ropes 10;

[0032] The steering gear 1 is connected to the inner ring of the one-way bearing 3 through the steering gear connecting shaft 2, the outer ring of the one-way bearing 3 is fixedly connected to the suspension bracket 5, the suspension bracket 5 includes an annular bracket 52 with a notch 51 and a radial support member 53, and the radial support member is used to fixedly connect the annular bracket to the outer ring of the one-way bearing, so that the suspension bracket can rotate unidirectionally under the action of the power provided by the steering gear and the control provided by the one-way bearing. The two sides of the notch 51 are respectively a support end 54 and a free end 55 of the annular bracket 52;

[0033] The perforated lock housing 6 includes more than two through holes 61 for longitudinally passing through the suspension ropes 10, and the through holes 61 are located below the annular bracket 52. A sub-throwing disc 9 with more than two rope passing holes 91 is arranged below the perforated lock housing 6. The perforated lock housing 6 and the sub-throwing disc 9 are directly or indirectly fixedly connected through a structure including a vertical bracket 8. The top of the suspension rope 10 is hung on the annular bracket 52, and the suspension rope 10 sequentially passes through the through hole 61 and the rope passing hole 91 downward, and the suspension rope below the sub-throwing disc 9 is used to connect with the object 13 to be thrown;

[0034] When the steering gear 1 drives the suspension bracket 5 to rotate unidirectionally, the position of the suspension rope 10 remains basically unchanged under the block of the hole wall at the peripheral position of the through hole 61. Therefore, when the suspension bracket 5 rotates, the suspension rope 10 and the suspension bracket 5 move relative to each other. When the free end 55 beside the notch of the suspension bracket 5 rotates above a certain through hole 61, the top of the suspension rope 10 falls off from the free end 55 and the notch on the annular bracket 52, and the object 13 connected to the suspension rope is thrown downward due to the falling of the suspension rope.

[0035] The present invention can continuously throw objects, improving efficiency and saving time. Due to the design of the sub-throwing disc, multiple objects of the present invention will not be entangled with each other due to the action of air flow and their own inertia in the air, and there will be no problem of failed distributed throwing.

[0036] In a specific embodiment, the vertical bracket 8 includes a vertical connecting rod 81 which is coaxially arranged with the servo connecting shaft 2 and is arranged below the servo connecting shaft 2. The continuous thrower also includes a torque limiting device 4 for keeping the suspension frame 5 stationary and not rotating when there is no external power drive. The torque limiting device 4 includes an inner ring and an outer ring, and a certain friction force is maintained between the inner ring and the outer ring. The inner ring of the torque limiting device 4 is arranged below the one-way bearing 3. The inner ring of the torque limiting device 4 is fixedly arranged on the outer periphery of the vertical connecting rod 81, and its outer ring has an upper extension member 41 extending upward in the height direction relative to the inner ring. The upper extension member 41 clamps and fixes the radial support member 53, and relies on the friction force between the inner ring and the outer ring of the torque limiting device 4 to keep the suspension frame 5 stationary and not rotating without external force drive.

[0037] In a specific embodiment, the continuous throwing device also includes a connecting and fixing sleeve 7 for fixing the perforated lock shell 6 and the vertical connecting rod 81, the vertical connecting rod 81 is set to a retractable structure, and the throwing plate 9 is detachably connected to the vertical connecting rod 81. The retractable vertical connecting rod 81 cooperates with the throwing plates 9 of different sizes, which can make the throwing of the mounting 13 more targeted, flexibly handle the mountings 13 of different volumes, and be more convenient when mounting. The throwing plate 9 is connected to the vertical connecting rod 81 by bolts, and the throwing plates 9 of different sizes can be replaced as needed. If the mounting 13 is larger in size, a relatively larger throwing plate 9 is used, and if the mounting 13 is smaller in size, a relatively larger throwing plate 9 is used.

[0038] In a specific implementation, the continuous thrower is used on a drone, and the continuous thrower further includes a remote control receiving device disposed on the steering engine 1 .

[0039] In a specific embodiment, the suspension bracket is configured to be a suspension bracket that can rotate unidirectionally clockwise or counterclockwise in a horizontal plane.

[0040] In a specific implementation, the radial support member 53 is a rod-shaped structure, and one end of the radial support member 53 is fixedly connected to the support end 54 .

[0041] In a specific embodiment, the top of the suspension rope 10 is a rope loop or hook type, the rope loop or hook is used to hang on the annular bracket, and falls off from the notch on the annular bracket during casting; the hole size of the rope hole is smaller than the size of the rope loop or hook, so that the rope loop or hook falls above the rope hole, so that the top of the suspension rope is hung on the casting plate and the suspension rope will not fall off the casting device. Setting it as a hook type makes it very convenient to hang the hanging object.

[0042] In a specific embodiment, a plurality of through holes provided on the perforated lock housing 6, a plurality of rope passing holes provided on the distributing disc 9, and a plurality of suspension ropes 10 are all arranged at uniform intervals in the circumferential direction, and the number of the through holes, the rope passing holes, and the suspension ropes is 3 to 30. Arranging at uniform intervals in the circumferential direction can make the gravity of the continuous thrower itself more symmetrical and balanced.

[0043] In a specific embodiment, the continuous thrower further includes a lock cover 11, the lock cover 11 is arranged above the suspension bracket 5, below the steering gear 1, and the steering gear connecting shaft 2 passes through the lock cover 11, and the lock cover 11 is detachably connected to the perforated lock housing 6; the continuous thrower further includes a steering gear guard plate 12 for protecting the steering gear 1, and the steering gear guard plate 12 is fixedly connected to the lock cover 11.

[0044] In a specific embodiment, the central angle corresponding to the circumferential width of the notch is 5 to 60°. With the rotation control of the steering gear, the ring-shaped bracket rotates through the transmission of the steering gear connecting shaft, the one-way bearing, and the radial support rod, and the suspension rope hung on the ring-shaped bracket is restricted by the through hole of the perforated lock housing, and finally slides off from the notch of the ring-shaped bracket to achieve the purpose of throwing.

[0045] The through holes on the perforated lock housing 6 are distributed directly below the ring-shaped bracket, which is not only more convenient for installing the rope, but also enables the suspension rope to slide more smoothly when it slides off the end of the ring-shaped bracket.

[0046] In the present invention, the load 13 under the suspension rope can be either disaster relief materials with a relatively small volume or disaster relief materials with a relatively large volume such as lifebuoys.
