Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and more specifically, to a precision throwing device and a unmanned aerial vehicle. Background Art

[0002] With the development and construction of urbanization, the coverage rate of overhead distribution lines has gradually increased. It is very important for power companies to ensure the reliability of power supply. The suddenness and uncertainty of various tripping accidents of distribution overhead lines require manual line patrol once a tripping accident occurs, which is time-consuming, labor-intensive and inefficient, seriously affecting the reliability of power supply and causing unnecessary power outages. Tripping accidents of distribution overhead lines are caused by lightning strikes, tree touches, human external forces, equipment failures, and bird damage. Among them, power outages caused by bird damage are particularly numerous. Bird nesting is everywhere, which seriously endangers the safe and reliable operation of power equipment. In order to reduce the number of grounding faults and tripping caused by bird damage, the power department has set up bird repellers (such as a wind-powered bird repeller with a publication number of CN206612089U) to interfere with birds through movement, sound and light to achieve the purpose of bird repelling.

[0003] However, most of the existing bird repellers are installed by manually climbing up the transmission tower. Electric workers will waste a lot of time and energy climbing up and down the transmission tower, which makes the installation of the bird repeller time-consuming and laborious. Therefore, the existing technology requires a bird repeller installation device that can avoid climbing the transmission tower.

[0004] The throwing device in the prior art is usually provided with a mounting slot, and a mounting shaft for controlling the opening and closing of the mounting slot is provided at the opening of the mounting slot, and the opening and closing of the mounting shaft are controlled by the opening and closing of the mounting shaft. However, due to the limited space of a mounting slot, only one bird repellent can be thrown at a time, and multiple bird repellents cannot be thrown. Summary of the invention

[0005] The present invention overcomes the problem that the throwing device in the prior art can only throw one bird repeller and has insufficient throwing efficiency, and provides a precise throwing device and a drone, which can simultaneously throw multiple bird repellers, thereby improving the installation efficiency of the bird repellers.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: a precise throwing device, comprising: A mounting frame, which is provided with a plurality of throwing units; The casting unit includes a clamp seat and a deflection rod. The clamp seat is provided with a hanging groove opening downward. Pin rods for controlling the opening and closing of the hanging groove are slidably provided on both sides of the hanging groove. The end of the pin rod away from the hanging groove is rotatably connected to the end of the connecting rod. The end of the connecting rod away from the pin shaft is rotatably connected to the end of the deflection rod. The end of the deflection rod away from the pin shaft is provided with a deflection center hole. The power transmission device drives the deflection rod to rotate around the deflection center hole through the transmission component, thereby controlling the pin rod to open or close the hanging slot.

[0007] In the present invention, by arranging a plurality of throwing units on the mounting frame, different numbers of throwing units can be arranged as needed, and each throwing unit can transport a bird repeller into the air. When the bird repeller is transported to high altitude by the present application, the deflection rod is driven to rotate around the deflection center hole by the power transmission device, so that the deflection rod drives the connecting rod to move, thereby making the pin rod slide, and then controlling the pin rod to open and close the opening of the hanging groove, so that the bird repeller hung on the pin rod is thrown onto the transmission tower. Therefore, through the present application, multiple bird repellers can be transported at one time, and multiple bird repellers can be thrown at the same time, thereby improving the installation efficiency of the bird repeller.

[0008] Preferably, the number of the power output devices corresponds to the number of the throwing units, and the output end of the power output device is a rotating shaft, which is connected to the deflection center hole.

[0009] Different throwing units are controlled by different power output devices, so that each throwing unit can be controlled.

[0010] Preferably, the transmission assembly is a transmission rod connected to the output end of the power output device, and the deflection center holes of the plurality of deflection rods are fixedly connected to the transmission rod.

[0011] By controlling the power output device, the rotation of the transmission rod is controlled, and all the bird repellers can be uniformly controlled to be thrown uniformly.

[0012] Preferably, the transmission assembly includes a transmission center shaft connected to the output end of the power transmission device, a plurality of transmission rods arranged in a circumferential direction around the transmission center shaft, and a power transmission assembly; the transmission center shaft drives the transmission rod to rotate through the power transmission assembly, and the end of the transmission rod away from the transmission center shaft is connected to the deflection center hole of the deflection rod.

[0013] By setting up a power transmission assembly, when the transmission center shaft rotates, the transmission rod can be driven to rotate.

[0014] Preferably, six transmission rods are arranged in the circumferential direction of the transmission center axis.

[0015] The six transmission rods are evenly distributed around the transmission center axis, which makes space utilization more reasonable and the overall structure more compact.

[0016] Preferably, the power transmission assembly includes a driving bevel gear coaxially connected to the transmission center shaft and a driven bevel gear fixedly arranged at the end of the transmission rod. The driving bevel gear and the driven bevel gear are meshed and driven through a gear pair.

[0017] Through the meshing transmission of the driving bevel gear and the driven bevel gear, when the transmission center shaft rotates, the transmission rod can be driven to rotate, so that the two mutually perpendicular shafts can transmit to each other.

[0018] Preferably, the number of the transmission rods is N, and the corresponding angle of the driving teeth arranged on the driving bevel gear is 360° / N.

[0019] This means that when the driving bevel gear rotates, only one driven bevel gear meshes with it at a time. Therefore, by controlling the rotation angle of the transmission center shaft through the controller, it is possible to control one driven bevel gear to rotate, thereby achieving the casting of a single bird repeller.

[0020] Preferably, a fixing ring is provided on the mounting frame, and the fixing ring is installed on the periphery of the transmission center shaft; a plurality of supporting holes matching with the transmission rod are provided on the fixing ring, and the transmission rod passes through the supporting holes and is connected to the transmission center shaft.

[0021] The setting of the fixing ring makes the transmission rod more stable during transmission, thereby improving the stability of the transmission.

[0022] Preferably, the power output device is a steering gear.

[0023] The servo receives the command signal from the autopilot and works. When the UAV is driving, the clutch remains disengaged and the transmission parts do not function, making it stable and efficient.

[0024] The present application also discloses a drone, comprising the above-mentioned precise throwing device.

[0025] By cooperating with drones, accurate throwing can be achieved.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention can set different numbers of throwing monomers according to needs by setting a plurality of throwing monomers on the mounting frame, and each throwing monomer can transport a bird repeller into the air. When the bird repeller is transported to high altitude by the present application, the deflection rod is driven to rotate around the deflection center hole by the power transmission device, so that the deflection rod drives the connecting rod to move, thereby making the pin rod slide, and then controlling the pin rod to open and close the opening of the hanging groove, so that the bird repeller hung on the pin rod is thrown onto the transmission tower. Therefore, through the present application, multiple bird repellers can be transported at one time, and multiple bird repellers can be thrown at the same time, thereby improving the installation efficiency of the bird repeller.

[0038] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example 1: Reference Figure 1 As shown, a precision casting device comprises: A mounting frame 1, which is provided with a plurality of throwing units 3; The casting unit 3 includes a clamp seat 31 and a deflection rod 32. The clamp seat 31 is provided with a downwardly opening hanging groove 311. Pin rods 33 for controlling the opening and closing of the hanging groove 311 are slidably provided on both sides of the hanging groove 311. The end of the pin rod 3 away from the hanging groove 311 is rotatably connected to the end of the connecting rod 34. The end of the connecting rod 34 away from the pin shaft is rotatably connected to the end of the deflection rod 32. The end of the deflection rod 32 away from the pin shaft is provided with a deflection center hole 321. The power transmission device drives the deflection rod 32 to rotate around the deflection center hole 321 through the transmission assembly, thereby controlling the pin rod 33 to open or close the hanging groove 311.

[0039] In the present application, by setting a plurality of throwing monomers 3 on the mounting frame 1, different numbers of throwing monomers 3 can be set as needed, and each throwing monomer 3 can transport a bird repeller to the air. When the bird repeller is transported to the sky through the present application, the deflection rod 32 is driven to rotate around the deflection center hole 321 by the power transmission device, so that the deflection rod 32 drives the connecting rod 34 to move, so that the pin rod 33 slides, and then the pin rod 33 is controlled to open and close the opening of the hanging groove 311, so that the bird repeller hung on the pin rod 33 is thrown onto the transmission tower. Therefore, through the present application, multiple bird repellers can be transported at one time, and multiple bird repellers can be thrown at the same time, thereby improving the installation efficiency of the bird repeller.

[0040] Example 2: Reference Figure 1 to Figure 2 As shown, a precision throwing device comprises: a mounting frame 1, a seat plate 2 and a throwing unit 3, wherein a plurality of throwing units 3 are arranged on the mounting frame 1. The arrangement of the mounting frame 1 facilitates the installation of a plurality of throwing units 3 on a drone.

[0041] The seat plate 2 is fixedly mounted on the mounting frame 1 , and the throwing unit 3 is fixedly mounted on the mounting frame 1 through the seat plate 2 .

[0042] The casting unit 3 includes a clamp seat 31 and a deflection rod 32. The clamp seat 31 is provided with a hanging groove 311 opening downward. The two sides of the hanging groove 311 are slidably provided with pins 33 for controlling the opening and closing of the hanging groove 311. The pins 33 are inserted into the clamp seat 31. The end of the pin 33 away from the hanging groove 311 is rotatably connected to the end of the connecting rod 3434. The end of the connecting rod 34 away from the pin shaft is rotatably connected to the end of the deflection rod 32. The end of the deflection rod 32 away from the pin shaft is provided with a deflection center hole 321. The deflection rod 32 is a long strip structure, and the deflection center hole 321 is provided at the end of one end of the deflection rod 32.

[0043] The power output device 4 is fixedly mounted on the seat plate 2 . The power output device 4 drives the deflection rod 32 to rotate around the deflection center through the transmission assembly, thereby controlling the pin rod 33 to open or close the hanging groove 311 .

[0044] The number of the power output devices 4 corresponds to the number of the throwing units 3 , and the output end of the power output device 4 is a rotating shaft, which is connected to the deflection center.

[0045] In this embodiment, two or more groups of throwing units 3 are provided.

[0046] Taking two groups of throwing units 3 as an example, the two groups of throwing units 3 are respectively connected to a corresponding power transmission device. Each power output device 4 controls a throwing unit 3 separately. The power transmission device includes but is not limited to a drive motor, a steering gear and other devices. In the present application, taking the steering gear as an example, the output end of the steering gear is a rotating shaft, so the transmission assembly is a rotating shaft, and the end of the rotating shaft away from the steering gear is fixedly connected to the deflection center hole 321. When the rotating shaft rotates, the rotating shaft can drive the deflection rod 32 to rotate around the deflection center hole 321, so that the deflection rod 32 drives the connecting rod 34 to move, thereby causing the pin rod 33 to slide, and then controlling the pin rod 33 to open and close the opening of the hanging groove 311.

[0047] The working principle of the present application is as follows: the number of the throwing units 3 is two or more groups, and two groups are taken as an example in this embodiment. All the throwing units 3 are fixed to the bottom of the UAV by using the mounting frame 1, and the control ends of the servos of all the throwing units 3 are electrically connected to the controller of the UAV. The remote control device of the UAV can control the rotation direction and rotation range of all the servos through the controller of the UAV respectively; control all the servos to rotate so that the servos drive the connecting rod 34 to move through the deflection rod 32, and the connecting rod 34 drives the pin rod 33 to slide in the clamp seat 31, so that the pin rod 33 closes the lower opening of the hanging groove 311, and the bird repeller is connected to the hanging rope 75 through the hanging ring 74 thereon, and the hanging rope 75 is hung on the pin rod 33 in the hanging groove 311; When the drone drives two or more groups of throwing units 3 to move above the transmission tower, each group of steering gears is controlled to rotate by the remote controller, so that each group of steering gears drives the deflection rod 32 to rotate through the rotating shaft at the output end, and the deflection rod 32 drives the connecting rod 34 to move, and the connecting rod 34 drives the pin rod 33 to slide in the clamp seat 31, so that the pin rod 33 opens the opening of the hanging groove 311 and makes the pin rod 33 completely slide out of the hanging groove 311. At this time, the hanging rope 75 loses its attachment and falls off from the pin rod 33, and then the bird repeller connected under the hanging rope 75 follows the fall, because the weight of the magnet block 73 accounts for 2.5% of the total weight of the bird repeller. The weight of the bird repeller is more than 70%, and the wind resistance of the wind rotor 72 is relatively high, so the falling bird repeller will fall with the magnet block 73 facing downward. When the bottom surface of the bird repeller, that is, the surface where the magnet block 73 is located, contacts the iron frame of the transmission tower, the bottom surface of the bird repeller is magnetically attracted to the iron frame of the transmission tower under the magnetic attraction of the magnet block 73. By individually controlling each group of servos, each group of bird repellers can be controlled to be released at different times and different positions, thereby completing the throwing and installation operation of the bird repeller. If the landing point of the bird repeller deviates due to external factors, the bird repeller can be recovered and then re-mounted and thrown.

[0048] Example 3: Reference Figure 1 , Figure 3 As shown, a precision throwing device comprises: a mounting frame 1, a seat plate 2 and a throwing unit 3, wherein a plurality of throwing units 3 are arranged on the mounting frame 1. The arrangement of the mounting frame 1 facilitates the installation of a plurality of throwing units 3 on a drone.

[0049] The seat plate 2 is fixedly mounted on the mounting frame 1 , and the throwing unit 3 is fixedly mounted on the mounting frame 1 through the seat plate 2 .

[0050] The casting unit 3 includes a clamp seat 31 and a deflection rod 32. The clamp seat 31 is provided with a hanging groove 311 opening downward. The two sides of the hanging groove 311 are slidably provided with pins 33 for controlling the opening and closing of the hanging groove 311. The pins 33 are inserted into the clamp seat 31. The end of the pin 33 away from the hanging groove 311 is rotatably connected to the end of the connecting rod 34. The end of the connecting rod 34 away from the pin shaft is rotatably connected to the end of the deflection rod 32. The end of the deflection rod 32 away from the pin shaft is provided with a deflection center hole 321. The deflection rod 32 is a long strip structure, and the deflection center hole 321 is provided at the end of one end of the deflection rod 32.

[0051] The power output device 4 is fixedly mounted on the seat plate 2 . The power output device 4 drives the deflection rod 32 to rotate around the deflection center through the transmission assembly, thereby controlling the pin rod 33 to open or close the hanging groove 311 .

[0052] In this embodiment, only one power output device 4 is provided, and the power transmission device includes but is not limited to a drive motor, a steering gear, etc. In this embodiment, the steering gear is taken as an example.

[0053] The transmission assembly is a transmission rod 5 connected to the output end of the steering gear, and the deflection center holes 321 of the plurality of deflection rods 32 are all concentrically fixedly connected to the transmission rod 5 .

[0054] The output end of the steering gear is connected to the transmission rod 5, and the rotation of the steering gear can drive the transmission rod 5 to rotate.

[0055] In this embodiment, two casting units 3 are used as an example, and the deflection center holes 321 of the deflection rods 32 on the two casting units 3 are connected to the transmission rod 5. (Of course, the number of casting units 3 can also be set to multiple, and it is only necessary to connect the deflection center holes 321 on the deflection rods 32 on multiple casting units 3 to the transmission rod 5, and drive multiple deflection rods 32 to rotate through one transmission rod 5.) The working principle of this embodiment is as follows: the number of throwing units 3 is two or more groups. Taking two groups of throwing devices as an example, all the throwing units 3 are fixed to the bottom of the drone by using a mounting frame 1, the control end of the servo motor is electrically connected to the controller of the drone, and the remote control device of the drone can be controlled by the controller of the drone, and the controller can control the rotation direction and rotation range of the servo motor; the rotation of the servo motor causes the servo motor to drive the deflection rod 32 through the transmission rod 5, the deflection rod 32 drives the connecting rod 34 to move, and the connecting rod 34 drives the pin rod 33 to slide in the clamp seat 31, so that the pin rod 33 closes the opening of the hanging groove 311, and the bird repeller is connected to the hanging rope 75 through the hanging ring 74 thereon, and the hanging rope 75 is hung on the pin rod 33 in the hanging groove 311.

[0056] When the drone drives the two groups of throwing monomers 3 to move above the transmission tower, the remote control controls the steering gear to rotate, so that the steering gear drives the transmission rod 5 to rotate, and the transmission rod 5 drives all the deflection rods 32 coaxially connected thereto to rotate, and then the deflection rod 32 drives the connecting rod 34 connected thereto to move, and the connecting rod 34 drives the pin rod 33 to slide in the clamp seat 31, so that the pin rod 33 opens the opening of the hanging groove 311 and makes the pin rod 33 completely slide out of the hanging groove 311, at this time, the hanging rope 75 loses its attachment and falls off from the pin rod 33, and then the bird repeller connected below the hanging rope 75 follows the fall, because the magnetic The weight of the iron block 73 accounts for more than 70% of the total weight of the bird repeller. In addition, the wind resistance of the wind rotor 72 is relatively high, so the falling bird repeller will fall with the magnet block 73 facing downward. When the bottom surface of the bird repeller, that is, the surface where the magnet block 73 is located, contacts the iron frame of the transmission tower, the bottom surface of the bird repeller is magnetically attracted to the iron frame of the transmission tower under the magnetic attraction of the magnet block 73, completing the installation of the bird repeller. By controlling the servo, all the bird repellers can be uniformly controlled to be thrown uniformly. If the landing point of the bird repeller deviates due to external factors, the bird repeller can be recovered and then re-mounted and thrown.

The arrangement of the mounting frame 1 facilitates the installation of a plurality of throwing units 3 on a drone.

[0058] The seat plate 2 is fixedly mounted on the mounting frame 1 , and the throwing unit 3 is fixedly mounted on the mounting frame 1 through the seat plate 2 .

[0059] The casting unit 3 includes a clamp seat 31 and a deflection rod 32. The clamp seat 31 is provided with a hanging groove 311 opening downward. The two sides of the hanging groove 311 are slidably provided with pins 33 for controlling the opening and closing of the hanging groove 311. The pins 33 are inserted into the clamp seat 31. The end of the pin 33 away from the hanging groove 311 is rotatably connected to the end of the connecting rod 34. The end of the connecting rod 34 away from the pin shaft is rotatably connected to the end of the deflection rod 32. The end of the deflection rod 32 away from the pin shaft is provided with a deflection center hole 321. The deflection rod 32 is a long strip structure, and the deflection center hole 321 is provided at the end of one end of the deflection rod 32.

[0060] In this embodiment, only one power output device 4 is provided, and a plurality of throwing units 3 are arranged in a circular array, and the plurality of throwing units 3 are all fixed on a mounting frame 1. The output end of the power output device 4 is connected to a transmission center shaft 51, and the transmission center shaft 51 is provided at the center position of the circular array surrounded by the plurality of throwing units 3.

[0061] The transmission assembly in this embodiment includes a transmission center shaft 51 connected to the output end of the power transmission device, a plurality of transmission rods 5 arranged in a circumferential direction around the transmission center shaft 51, and a power transmission assembly; the transmission center shaft 51 drives the transmission rod 5 to rotate through the power transmission assembly, and the end of the transmission rod 5 away from the transmission center shaft 51 is connected to the deflection center hole 321 of the deflection rod 32.

[0062] The power transmission assembly includes a driving bevel gear 52 coaxially connected to the transmission center shaft 51 and a driven bevel gear 53 fixedly arranged at the end of the transmission rod 5. The driving bevel gear 52 and the driven bevel gear 53 are meshed and driven through a gear pair. Through the meshing transmission of the driving bevel gear 52 and the driven bevel gear 53, when the transmission center shaft 51 rotates, the transmission rod 5 can be driven to rotate.

[0063] In this embodiment, six transmission rods 5 are arranged in the circumferential direction of the transmission center axis 51 .

[0064] The working principle of this embodiment is as follows: this embodiment is suitable for the situation that multiple bird repellers need to be thrown and each bird repeller does not need to be thrown independently. Only one group of servos is set, and the other throwing monomers 3 are arranged in a circular array around the transmission center axis 51: a driving bevel gear 52 is fixedly set on the transmission center axis 51; a bearing seat 6 is fixed under the seat plate 2 of each group of throwing monomers 3, and the bearing seat 6 transmission rod 5 plays a supporting role, and the bearing seat 6 and the transmission rod 5 in the throwing monomer 3 are rotatably matched; each transmission rod 5 is concentrically fixed with a driven bevel gear 53 at the end away from the deflection center hole 321; all the driven bevel gears 53 are meshed with the driving bevel gear 52, and the driving bevel gear 52 is fixed on the transmission center axis 51 of the servo, and the servo is directly fixed on the mounting frame 1 above all the throwing monomers 3.

[0065] The number of the throwing units 3 is two or more groups, and six groups of throwing units 3 are provided in this embodiment. All the throwing units 3 are fixed to the bottom of the UAV by the mounting frame 1, and the control end of the servo is electrically connected to the controller of the UAV, and the remote control device of the UAV can control the rotation direction and rotation range of the servo through the controller of the UAV; the rotation of the servo drives all the driven bevel gears 53 meshed thereon to rotate through the driving bevel gear 52, and the driven bevel gear 53 drives the transmission rod 5 coaxially connected thereto to rotate, and the deflection rod 32 fixed on each group of transmission rods 5 follows the deflection, and the deflection rod 32 drives the connecting rod 34 to move, and the connecting rod 34 drives the pin rod 33 to slide in the clamp seat 31, so that the pin rod 33 closes the opening of the hanging groove 311, and the bird repeller is connected to the hanging rope 75 through the hanging ring 74 thereon, and the hanging rope 75 is mounted on the pin rod 33 in the hanging groove 311.

[0066] When the drone drives two or more groups of throwing units 3 to move above the transmission tower, the remote control controls the steering gear to rotate, so that the steering gear drives all the driven bevel gears 53 engaged thereon to rotate through the driving bevel gear 52, and the driven bevel gear 53 drives its coaxial transmission rod 5 to rotate, and the deflection rod 32 fixed on each group of transmission rods 5 follows the deflection, and the deflection rod 32 drives the connecting rod 34 to move, and the connecting rod 34 drives the pin rod 33 to slide in the clamp seat 31, so that the pin rod 33 opens the opening of the hanging groove 311 and makes the pin rod 33 completely slide out of the hanging groove 311, at this time, the hanging rope 75 loses its attachment and falls off from under the pin rod 33, and then the hanging rope 75 The bird repeller connected below follows the fall, because the weight of the magnet block 73 accounts for more than 70% of the total weight of the bird repeller, and the wind resistance of the wind rotor 72 is relatively high, so the falling bird repeller will fall with the magnet block 73 facing downward. When the bottom surface of the bird repeller, that is, the surface where the magnet block 73 is located, contacts the iron frame of the transmission tower, the bottom surface of the bird repeller is magnetically attracted to the iron frame of the transmission tower by the magnetic force of the magnet block 73, and the installation of the bird repeller is completed.

[0071] The transmission assembly in this embodiment includes a transmission center shaft 51 connected to the output end of the power transmission device, a plurality of transmission rods 5 arranged in a circumferential direction around the transmission center shaft 51, and a power transmission assembly; the transmission center shaft 51 drives the transmission rod 5 to rotate through the power transmission assembly, and the end of the transmission rod 5 away from the transmission center shaft 51 is connected to the deflection center hole 321 of the deflection rod 32.

[0072] The power transmission assembly includes a driving bevel gear 52 coaxially connected to the transmission center shaft 51 and a driven bevel gear 53 fixedly arranged at the end of the transmission rod 5. The driving bevel gear 52 and the driven bevel gear 53 are meshed and driven through a gear pair. Through the meshing transmission of the driving bevel gear 52 and the driven bevel gear 53, when the transmission center shaft 51 rotates, the transmission rod 5 can be driven to rotate.

[0073] In this embodiment, six transmission rods 5 are arranged in the circumferential direction of the transmission center axis 51 .

[0074] The structure of this embodiment is similar to that of the embodiment, except that, in the embodiment, although the transmission center shaft 51 can simultaneously control multiple throwing units 3 to throw the bird repellers, it is not possible to throw individual bird repellers one by one, and therefore is not suitable for occasions where a single bird repeller needs to be thrown.

[0075] Therefore, the scope of the driving teeth on the driving bevel gear 52 is improved in the present application. Specifically, the number of the transmission center rods is N, and the corresponding angle of the driving teeth provided on the driving bevel gear 52 is 360 ° / N. Taking the six transmission rods 5 in the present embodiment as an example, the corresponding angle of the driving teeth provided on the driving bevel gear 52 in the present embodiment is 60 °. This makes it possible that when the driving bevel gear 52 rotates, only one driven bevel gear 53 is engaged with it at a time. Therefore, by controlling the angle of rotation of the transmission center shaft 51 through the controller, it is possible to control a driven bevel gear 53 to rotate, thereby realizing the casting of a single bird repeller. For example, in the present embodiment, it is only necessary to control the transmission center shaft 51 to rotate only 60 ° each time, so that a bird repeller can be cast each time.

[0076] The mounting frame 1 is provided with a fixing ring 8, which is installed on the periphery of the transmission center shaft 51; the fixing ring 8 is provided with a plurality of supporting holes 81 that match the transmission rod 5, and the transmission rod 5 passes through the supporting holes 81 and is connected to the transmission center shaft 51 by gear transmission. The setting of the fixing ring 8 makes the transmission rod 5 more stable during transmission, thereby improving the stability of transmission.

[0077] In this embodiment, since the driving bevel gear 52 is meshed with only one driven bevel gear 53 at a time, when the other driven bevel gears 53 not meshed with the driving bevel gear 52 are in a free rotation state, in order to prevent the other driven bevel gears 53 not meshed with the driving bevel gear 52 from rotating, the rotating rod and the support hole 81 are interference fit. The friction between the interference fit of the transmission rod 5 and the support hole 81 is small, which can limit the rotation of the transmission rod 5 when it is not meshed with the driving gear, without affecting the rotation of the transmission rod 5 driven by the driving bevel gear.

[0078] The working principle of this embodiment is as follows: this embodiment is suitable for the situation that multiple bird repellers need to be thrown and each bird repeller can be thrown independently, and a servo is provided, and other throwing monomers 3 are arranged in a circular array on the transmission center axis 51: a driving bevel gear 52 is fixedly provided on the transmission center axis 51; a bearing seat 6 is fixed under the seat plate 2 of each group of throwing monomers 3, and the bearing seat 6 and the transmission rod 5 in the throwing monomer 3 are rotatably matched; a driven bevel gear 53 is concentrically fixed at the end of each group of transmission rods 5 away from the deflection center hole 321; all the driven bevel gears 53 are meshed with the driving bevel gear 52, and the driving bevel gear 52 is fixed on the transmission center axis 51 of the servo, and the servo is directly fixed on the mounting frame 1 above all the throwing monomers 3.

[0079] The number of the throwing units 3 is two or more groups, and six groups of throwing units 3 are provided in this embodiment. All the throwing units 3 are fixed to the bottom of the UAV by the mounting frame 1, and the control end of the servo is electrically connected to the controller of the UAV. The remote control device of the UAV can control the rotation direction and rotation range of the servo through the controller of the UAV; the servo is controlled to rotate so that the servo drives the driven bevel gear 53 meshed thereon to rotate through the driving bevel gear 52, and the driven bevel gear 53 drives its coaxial transmission rod 5 to rotate, and the deflection rod 32 fixed on each group of transmission rods 5 follows the deflection, and the deflection rod 32 drives the connecting rod 34 to move, and the connecting rod 34 drives the pin rod 33 to slide in the clamp seat 31, so that the pin rod 33 closes the lower opening of the hanging groove 311, and the bird repeller is connected to the hanging rope 75 through the hanging ring 74 thereon, and the hanging rope 75 is mounted on the pin rod 33 in the hanging groove 311.

[0080] When the drone drives two or more groups of throwing units 3 to move above the transmission tower, this embodiment takes six groups of throwing units as an example: the servo is controlled by the remote control to control the rotation angle of the transmission center axis 51 (60° in this embodiment), so that the servo drives a driven bevel gear 53 to rotate through the driving bevel gear 52, and the driven bevel gear 53 drives its coaxial transmission rod 5 to rotate, and the deflection rod 32 fixed on the throwing unit 3 follows the deflection, the deflection rod 32 drives the connecting rod 34 to move, and the connecting rod 34 drives the pin rod 33 to slide in the clamp seat 31, so that the pin rod 33 opens the lower opening of the hanging groove 311, and the pin rod 33 completely slides out of the hanging groove 311, and the hanging rope 75 loses its mounting attachment. The bird repeller falls off from the pin rod 33, and then the bird repeller connected to the lower part of the hanging rope 75 follows the fall. Because the weight of the magnet block 73 accounts for more than 70% of the total weight of the bird repeller, and the wind resistance of the wind rotor 72 is relatively high, the falling bird repeller will fall with the magnet block 73 facing downward. When the bottom surface of the bird repeller, that is, the surface where the magnet block 73 is located, contacts the iron frame of the transmission tower, the bottom surface of the bird repeller is magnetically attracted to the iron frame of the transmission tower under the magnetic attraction of the magnet block 73, and the installation of the bird repeller is completed. By controlling the rotation angle of the output end of the retained servo, all the bird repellers can be controlled to be thrown one by one in turn. If the landing point of the bird repeller deviates due to external factors, the bird repeller can be recovered and then re-mounted and thrown.

[0081] Example 6: Reference Figures 1 to 10 As shown, the structures of this embodiment and embodiment 1 to embodiment 2 are similar, except that the bird repeller includes a rotatable wind rotor 72 as its main body, and the wind rotor 72 is rotatably fitted on a hollow seat 71 made of a hollow material by an axle rod. The hollow seat 71 is away from the center of one end of the wind rotor 72, and has a magnet block 73 embedded and fixed therein. A ring 74 for connecting a hanging rope 75 is provided on the side of the hollow seat 71 close to one end of the wind rotor 72. The weight of the magnet block 73 accounts for more than % of the total weight of the bird repeller, and the wind resistance of the wind rotor 72 is greater than the wind resistance of the hollow seat 71.

[0082] The hanging rope 75 is made of water-soluble rope. When the transmission tower outdoors encounters rain, the hanging rope 75 will dissolve in water to avoid affecting the rotation of the wind rotor 72; the wind rotor 72 will rotate when encountering wind to achieve the purpose of driving away birds. If necessary, the fan blades on the wind rotor 72 are painted with reflective paint to reflect light to increase the bird-repelling effect.

[0083] Example 7: Reference Figures 1 to 10 As shown, a drone includes a precision throwing device as described in any one of Examples 1 to 7.
