[0005] 2. When a drone is flying, birds can easily land on top of the drone, causing the load on the drone to increase, resulting in increased damage to the drone. Summary of the invention

[0006] The purpose of the present invention is to address the problems raised in the above-mentioned background technology and to provide a security drone that drives away birds by producing a loud sound through impact, reciprocatingly sucking and discharging bird repellent during the process to prevent birds from approaching the drone and at the same time giving a slight electric shock to birds that land on the drone.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A security drone, comprising:

[0009] A machine body, wherein a plurality of propellers are arranged on the machine body, a box body is arranged above the machine body, a driving rod is rotatably installed on the box body through a support plate, an axial flow fan blade is arranged on the driving rod, a rotating rod is rotatably installed in the box body, and a bevel gear is arranged at one end of the rotating rod and the driving rod close to each other, and the two bevel gears are meshed with each other;

[0010] The rotating rod is provided with a bird-repelling mechanism, and the bird-repelling mechanism repels birds by making a collision sound;

[0011] A suction mechanism is provided in the box body, and the suction mechanism is used to prevent birds from colliding with the drone.

[0012] Preferably, the bird-repelling mechanism includes two first support rods, two rotating shafts, two friction wheels, a plurality of hinged seats, a plurality of swinging plates, a plurality of first springs, a plurality of collision blocks and a friction mechanism. The two first support rods are mounted on the rotating rod, a rotating shaft is rotatably mounted under each of the first support rods, a friction wheel is fixedly connected to each of the rotating shafts, a plurality of swinging plates are hinged on the inner wall of the box through a plurality of hinged seats, the friction wheels are in contact and rolling with the swinging plates, each of the swinging plates is elastically connected to the inner wall of the box through a first spring, a plurality of collision blocks are arranged inside the box, a friction mechanism is arranged on the inner wall of the box, and the friction mechanism improves the bird-repelling effect by emitting metal friction noise.

[0013] Preferably, the friction mechanism comprises an annular tooth groove and two first gears, the annular tooth groove is mounted on the inner wall of the box body, the first gears are mounted on the two rotating shafts, and the two first gears are meshed with the annular tooth groove.

[0014] The cam is provided with a second spring which is arranged on the support frame, and the cam is provided with a plurality of springs which are arranged on the support frame and the plurality of springs are provided with a plurality of springs which are arranged on the support frame.

[0015] Preferably, the annular suction cylinder is connected to the interior of the storage box through a liquid inlet pipe, and the annular suction cylinder is connected to the outside through a liquid discharge pipe.

[0016] Preferably, both the liquid inlet pipe and the liquid outlet pipe are provided with a one-way valve.

[0017] Preferably, a trapezoidal protrusion is provided on the annular guide rail, and the guide wheel moves along the top of the annular guide rail.

[0018] Preferably, an arc-shaped fur block is installed on the rotating rod through a connecting rod, an annular glass sheet is installed on the box body, the arc-shaped fur block is in contact with the annular glass sheet, an annular conductive sheet is provided above the box body, and the annular conductive sheet is connected to the annular glass sheet through a conductive rod.

[0019] Compared with existing technologies, the advantages of this security drone are:

[0020] 1. The present invention provides a bird-repelling mechanism. When the UAV is shooting and patrolling at a high place, the driving rod can be driven to rotate by wind force, and the rotating rod can be further driven to rotate by the bevel gear, so that the first support rod can perform a circular motion. When the friction wheel under the first support rod moves to contact the swing plate, it will push the swing plate away from the collision block, and when the friction wheel is separated from the swing plate, the swing plate will hit the collision block under the elastic force of the first spring, so that the birds are driven away by the loud sound generated by the collision, preventing the birds from approaching the UAV.

[0021] 2. The present invention sets a friction mechanism. When the first support rod drives the rotating shaft and the friction wheel to perform circular motion, the first gear on the rotating shaft is always meshed with the annular tooth groove, so that the rotating shaft drives the friction wheel to rotate. Since the friction wheel and the swing plate are both made of metal, when the friction wheel contacts and pushes the swing plate, a harsh metal friction noise can be generated between the friction wheel and the swing plate, thereby improving the effect of expelling birds, effectively preventing birds from approaching and colliding with the drone, and avoiding damage to the drone.

[0022] 3. The present invention provides a suction mechanism. During the rotation of the rotating rod, the second support rod will be driven to perform circular motion, thereby driving the guide wheel to perform circular motion on the annular guide rail, driving the moving block to move synchronously in the annular suction cylinder, and the bird repellent in the storage box is drawn into the annular suction cylinder. When the guide wheel moves to the trapezoidal protrusion, the trapezoidal protrusion lifts the guide wheel so that the abutment block no longer abuts the transmission block. The moving block can automatically rebound to the initial position under the elastic force of the second spring, and the bird repellent in the annular suction cylinder is transported to the outside, so as to further expel the birds around the UAV, improve the expulsion effect on some birds that are not affected by noise, reduce the impact of birds on the UAV as much as possible, and increase the service life of the UAV.

[0023] 4. The present invention arranges an arc-shaped fur block and an annular glass sheet. When the rotating rod rotates, the arc-shaped fur block will be driven to move along the annular glass sheet, thereby generating static electricity on the annular glass sheet through friction, and further transmitting the static electricity to the annular conductive sheet through the conductive rod, so that the birds landing on the drone are slightly shocked by the generated static electricity, thereby preventing the birds from landing on the drone and avoiding the increase of the load of the drone due to carrying the birds, and at the same time will not harm the lives of the birds.

DETAILED DESCRIPTION

[0032] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0033] like Figure 1-Figure 7 As shown, a security drone comprises:

[0034] A machine body 1, on which a plurality of propellers 11 are arranged, a box body 12 is arranged above the machine body 1, a driving rod 13 is rotatably mounted above the box body 12 through a support plate, an axial flow fan blade 14 is arranged on the driving rod 13, a rotating rod 15 is rotatably mounted in the box body 12, and a bevel gear 16 is arranged at one end of the rotating rod 15 and the driving rod 13 close to each other, and the two bevel gears 16 are meshed with each other;

[0035] The rotating rod 15 is provided with a bird-repelling mechanism 2, which repels birds by making a collision sound;

[0036] A suction mechanism 3 is provided in the box body 12, and the suction mechanism 3 is used to prevent birds from colliding with the drone.

[0037] The bird-repelling mechanism 2 includes two first support rods 21, two rotating shafts 22, two friction wheels 23, a plurality of hinged seats 24, a plurality of swinging plates 25, a plurality of first springs 26, a plurality of collision blocks 27 and a friction mechanism 28. The two first support rods 21 are both mounted on the rotating rod 15. A rotating shaft 22 is rotatably mounted below each first support rod 21. A friction wheel 23 is fixedly connected to each rotating shaft 22. A plurality of swinging plates 25 are hingedly connected to the inner wall of the box body 12 through a plurality of hinged seats 24. The friction wheel 23 rolls in contact with the swinging plates 25. Each swinging plate 25 is elastically connected to the inner wall of the box body 12 through the first spring 26. A plurality of collision blocks 27 are arranged inside the box body 12. A friction mechanism 28 is arranged on the inner wall of the box body 12. The friction mechanism 28 improves the bird-repelling effect by emitting metal friction noise.

[0038] In view of the problem in the prior art that birds cannot be driven away when using security drones, which makes the drones easily scratched and collided by birds during flight and further causes damage to the drones, the present invention provides a bird-repelling mechanism 2. When the drone is shooting and patrolling at a high place, the axial flow fan blades 14 can be driven by wind to rotate, thereby rotating the driving rod 13, and further driving the rotating rod 15 to rotate through the bevel gear 16, so that the first support rod 21 can perform a circular motion. When the friction wheel 23 under the first support rod 21 moves to contact the swing plate 25, it will push the swing plate 25 away from the collision block 27, and when the friction wheel 23 detaches from the swing plate 25, the swing plate 25 will collide with the collision block 27 under the elastic force of the first spring 26, thereby driving the birds away through the loud sound generated by the collision, and preventing the birds from approaching the drone.

[0039] The friction mechanism 28 includes an annular tooth groove 281 and two first gears 282 . The annular tooth groove 281 is installed on the inner wall of the box body 12 . The first gears 282 are installed on the two rotating shafts 22 . The two first gears 282 are meshed with the annular tooth groove 281 .

[0040] In order to improve the effect of repelling birds when the friction wheel 23 contacts the swing plate 25, the present invention sets a friction mechanism 28. When the first support rod 21 drives the rotating shaft 22 and the friction wheel 23 to perform circular motion, the first gear 282 on the rotating shaft 22 is always meshed with the annular tooth groove 281, so that the rotating shaft 22 drives the friction wheel 23 to rotate. Since the friction wheel 23 and the swing plate 25 are both made of metal, when the friction wheel 23 contacts and pushes the swing plate 25, a harsh metal friction noise can be generated between the friction wheel 23 and the swing plate 25, thereby improving the effect of repelling birds, effectively preventing birds from approaching and colliding with the drone, and avoiding damage to the drone.

[0041] The suction mechanism 3 includes an annular suction cylinder 31, a fixed block 32, a second spring 33, a moving block 34, a storage box 35, a transmission block 36, a second support rod 37, two support blocks 38, two slide grooves 39, two rotating sleeves 310, two third springs 311, a stop block 312, a guide wheel 313 and an annular guide rail 314. The annular suction cylinder 31 is installed in the box body 12. A fixed block 32 is provided in the annular suction cylinder 31. The moving block 34 is elastically connected to the fixed block 32 through the second spring 33. The moving block 34 is sealingly slidably connected to the inner wall of the annular suction cylinder 31. A storage box is provided below the annular suction cylinder 31. 35, a transmission block 36 is provided above the moving block 34, a second support rod 37 is installed on the rotating rod 15, two support blocks 38 are installed at the bottom of the second support rod 37, each support block 38 is provided with a slide groove 39, a rotating sleeve 310 is slidably connected in each slide groove 39, each rotating sleeve 310 is elastically connected to the inner wall of the slide groove 39 through a third spring 311, a stop block 312 is installed on the two rotating sleeves 310 through a connecting rod, the stop block 312 is in contact with the transmission block 36, a guide wheel 313 is rotatably installed between the two rotating sleeves 310, and an annular guide rail 314 is provided above the annular suction cylinder 31.

[0042] The annular suction cylinder 31 is connected to the interior of the storage box 35 through the liquid inlet pipe, and the annular suction cylinder 31 is connected to the outside through the liquid discharge pipe 4.

[0043] Among them, both the liquid inlet pipe and the liquid discharge pipe 4 are provided with a one-way valve. Through the provided liquid inlet pipe, the liquid discharge pipe 4 and the one-way valve, when the stop block 312 pushes the moving block 34 through the transmission block 36, the bird repellent in the storage box 35 can only be pumped into the annular suction cylinder 31 through the liquid inlet pipe, and when the moving block 34 is restored to its original position under the elastic force of the second spring 33, the bird repellent in the annular suction cylinder 31 can only be discharged to the outside through the liquid discharge pipe 4.

[0044] Among them, a trapezoidal protrusion 5 is provided on the annular guide rail 314, and the guide wheel 313 moves along the top of the annular guide rail 314. When the guide wheel 313 moves to the position of the trapezoidal protrusion 5 on the annular guide rail 314, the trapezoidal protrusion 5 can push the guide wheel 313 upward, so that the stop block 312 moves synchronously until it is no longer in contact with the transmission block 36.

[0045] For some birds that are not affected by noise, the above-mentioned bird-repelling mechanism 2 and friction mechanism 28 have poor effects on driving away these birds. The present invention sets a suction mechanism 3. During the rotation of the rotating rod 15, it will also drive the second support rod 37 to perform a circular motion, thereby driving the guide wheel 313 to perform a circular motion on the annular guide rail 314. At this time, the guide wheel 313 and the rotating sleeve 310 are at the bottom under the elastic force of the third spring 311, so that the abutment block 312 always abuts against the transmission block 36. When the guide wheel 313 moves in a circular motion, the moving block 34 is driven to move synchronously in the annular suction cylinder 31, and the storage box 3 5 is sucked into the annular suction cylinder 31, and when the guide wheel 313 moves to the trapezoidal protrusion 5, the trapezoidal protrusion 5 lifts the guide wheel 313, thereby driving the rotating sleeve 310 and the stop block 312 to move upward synchronously, so that the stop block 312 no longer abuts against the transmission block 36, and the moving block 34 is able to automatically rebound to the initial position under the elastic force of the second spring 33, and the bird repellent in the annular suction cylinder 31 is transported to the outside, so as to further repel the birds around the UAV, improve the repelling effect on some birds that are not affected by noise, reduce the impact of birds on the UAV as much as possible, and increase the service life of the UAV.

[0046] In addition, an arc-shaped fur block 6 is installed on the rotating rod 15 through a connecting rod, and an annular glass sheet 61 is installed on the box body 12. The arc-shaped fur block 6 is in contact with the annular glass sheet 61. An annular conductive sheet 62 is provided above the box body 12, and the annular conductive sheet 62 is connected to the annular glass sheet 61 through a conductive rod.

[0047] In view of the problem in the prior art that birds are easy to land on the drone body, resulting in an increase in the load of the drone and an increase in the loss of the drone, the present invention provides an arc-shaped fur block 6 and an annular glass sheet 61. When the rotating rod 15 rotates, it will also drive the arc-shaped fur block 6 to move along the annular glass sheet 61, thereby generating static electricity on the annular glass sheet 61 through friction, and further transmitting the static electricity to the annular conductive sheet 62 through the conductive rod, so that the birds that land on the drone are slightly shocked by the generated static electricity, preventing the birds from landing on the drone and avoiding the increase in the load of the drone due to carrying the birds, while not harming the lives of the birds.

[0048] The present invention can be explained by the following operation mode:

[0049] S1: When the drone is shooting and patrolling at a high altitude, the wind drives the axial flow blades 14 to rotate, thereby rotating the driving rod 13, and further driving the rotating rod 15 to rotate through the bevel gear 16, so that the first support rod 21 performs a circular motion. When the friction wheel 23 under the first support rod 21 moves to contact the swing plate 25, it pushes the swing plate 25 away from the collision block 27. When the friction wheel 23 is separated from the swing plate 25, the swing plate 25 hits the collision block 27 under the elastic force of the first spring 26, and the birds are driven away by the loud sound generated by the collision;

[0050] S2: Since the first gear 282 on the rotating shaft 22 is always meshed with the annular tooth groove 281, the rotating shaft 22 drives the friction wheel 23 to rotate. Since the friction wheel 23 and the swing plate 25 are both made of metal, when the friction wheel 23 contacts and pushes the swing plate 25, the rotation of the friction wheel 23 generates a harsh metal friction noise between the friction wheel 23 and the swing plate 25, thereby improving the effect of expelling birds.

[0051] S3: During the rotation of the rotating rod 15, the second supporting rod 37 is also driven to perform circular motion, and the guide wheel 313 is driven to perform circular motion on the annular guide rail 314. The abutment block 312 always abuts against the transmission block 36, and drives the moving block 34 to move synchronously in the annular suction cylinder 31, so as to draw the bird repellent in the storage box 35 into the annular suction cylinder 31. When the guide wheel 313 moves to the trapezoidal protrusion 5, the trapezoidal protrusion 5 lifts the guide wheel 313, thereby driving the rotating sleeve 310 and the abutment block 312 to move upward synchronously, so that the abutment block 312 no longer abuts against the transmission block 36, and the moving block 34 is able to automatically rebound to the initial position under the elastic force of the second spring 33, and the bird repellent in the annular suction cylinder 31 is transported to the outside, so as to further expel the birds around the UAV, and improve the expulsion effect on some birds that are not affected by noise;

[0052] S4: When the rotating rod 15 rotates, it will also drive the arc-shaped fur block 6 to move along the annular glass sheet 61, thereby generating static electricity on the annular glass sheet 61 through friction, and further transmitting the static electricity to the annular conductive sheet 62 through the conductive rod, so that the birds landing on the drone are slightly shocked by the generated static electricity, thereby preventing the birds from landing on the drone.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
