[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1 to 6 As shown, this utility model provides a power line protection rope mounting structure for unmanned aerial vehicles (UAVs), comprising:

[0032] Fixture 1, with a round rod 2 fixedly installed inside the fixture 1;

[0033] The extrusion mechanism is located at the top of the fixed frame 1;

[0034] The fixing mechanism is set on the outer surface of the round rod 2;

[0035] The fixing mechanism includes two moving blocks 4. The interior of each moving block 4 is movably sleeved with the outer surface of the round rod 2. A spring 5 is fixedly installed on the outer surface of each moving block 4. The interior of the spring 5 is movably sleeved with the outer surface of the round rod 2. The other end of the spring 5 is fixedly connected to the interior of the fixing frame 1. A hanging device 3 is movably connected between the two moving blocks 4. An arc-shaped block 6 is fixedly installed at the top front of each moving block 4. A stop block 7 is fixedly sleeved inside the arc-shaped block 6. A rotating rod 8 abuts against the outer surface of the stop block 7. A fixed shaft 9 is movably sleeved inside the bottom end of the rotating rod 8. Circular plates 10 are fixedly sleeved at both ends of the fixed shaft 9. The outer surface of the circular plates 10 is fixedly connected to the outer surface of the hanging device 3. A torsion spring 11 is fixedly installed on the outer surface of the circular plates 10. The interior of the torsion spring 11 is movably sleeved with the outer surface of the fixed shaft 9. The other end of the circular plates 10 is fixedly connected to the outer surface of the rotating rod 8.

[0036] Due to the active sleeve connection of the rotating rod 8 and the fixed shaft 9, the rotating rod 8 can rotate around the fixed shaft 9, and when the rotating rod 8 rotates, the two torsion springs 11 will be deformed. Due to the design of the two torsion springs 11, the movement of the rotating rod 8 can be well reset. Due to the design of the two groups of springs 5, the spring force can be applied to the two moving blocks 4 to make the two moving blocks 4 fit together. At this time, the opposite ends of the two stop blocks 7 will contact and block the movement of the rotating rod 8. Due to the design of the circular rod 2, the movement of the two moving blocks 4 is limited. When the two moving blocks 4 move away from each other along the outer surface of the circular rod 2, the two clamping plates 12 will release the clamping and fixing of the hanging 3. At the same time, the two moving blocks 4 will compress the two groups of springs 5, and then the two stop blocks 7 will release the blocking of the rotating rod 8 in the opposite movement. At this time, the rotating rod 8 will rotate under the drive of the two torsion springs 11. When the rotating rod 8 rotates by 90 degrees, it will be blocked by the hanging 3. At this time, the hanging 3 will cooperate with the rotating rod 8 to form a locked state.

[0037] The extrusion mechanism comprises:

[0038] The cylinder 13 is fixedly connected to the top end of the fixed frame 1.

[0039] The extrusion block 14 is fixedly connected to the bottom end of the cylinder 13, and the outer surface of the extrusion block 14 is in contact with the outer surfaces of the two moving blocks 4.

[0040] When the cylinder 13 operates, the extrusion block 14 will move downward, and the outer surface of the extrusion block 14 will extrude and push the two moving blocks 4 to move away from each other. When the extrusion block 14 moves upward, due to the elastic force of the two springs 5, the two moving blocks 4 will move towards each other under the drive of the two springs 5.

[0041] The clamping plate 12 is fixedly installed on the side of the two moving blocks 4 facing each other, and the outer surface of the clamping plate 12 is in contact with the outer surface of the hanging 3.

[0042] When the two moving blocks 4 move, the two clamping plates 12 will move respectively. When the two moving blocks 4 fit together, the two clamping plates 12 can clamp and fix the hanging 3.

[0043] The sleeve ring 15 is movably installed in the bottom end of the hanging 3, and the sleeve ring 15 is made of metal.

[0044] Due to the design of the sleeve ring 15, the operator can conveniently connect the safety rope to the hanging 3.

[0045] The top end of the fixed frame 1 is fixedly installed with a connecting plate 16, the top end of the connecting plate 16 is fixedly installed with a fixed block 17, the back surface of the fixed block 17 is fixedly installed with a motor 18, the other end of the output shaft of the motor 18 is fixedly sleeved with a rotating shaft 19.

[0046] When the motor 18 operates, the rotating shaft 19 will rotate at this time.

[0047] The front end of the rotating shaft 19 is fixedly sleeved with a driving bevel gear 20, and the outer surface of the driving bevel gear 20 is connected with a driven bevel gear 21 in meshing.

[0048] When the rotating shaft 19 rotates, the driving bevel gear 20 will be driven to rotate, and since the outer surface of the driving bevel gear 20 is connected with the outer surface of the driven bevel gear 21 in meshing, the driving bevel gear 20 will drive the two driven bevel gears 21 to rotate at this time.

[0049] The inside of the driven bevel gear 21 is fixedly sleeved with a long shaft 22, and the outer surface of the long shaft 22 is movably sleeved with the inside of the fixed block 17.

[0050] When the two driven bevel gears 21 rotate, the two long shafts 22 will be driven to rotate in the inside of the fixed block 17 respectively.

[0051] The other end of the long shaft 22 is fixedly sleeved with a screw rod 23, the outer surface of the screw rod 23 is threadedly sleeved with a movable block 24, and the inside of the movable block 24 is hingedly connected with a moving rod 25.

[0052] When the two long shafts 22 rotate, the two screw rods 23 will be driven to rotate respectively, and since the outer surfaces of the two screw rods 23 are respectively threadedly sleeved with the insides of the two movable blocks 24, the two screw rods 23 will drive the two groups of moving rods 25 to move through the two movable blocks 24 at this time.

[0053] The inside of the other end of the moving rod 25 is fixedly sleeved with a movable shaft 26, and the two ends of the movable shaft 26 are movably sleeved with a rotating rod 27.

[0054] When the two groups of moving rods 25 move, the two groups of moving rods 25 will pull the two groups of rotating rods 27 at this time through the two groups of movable shafts 26, so that the two groups of rotating rods 27 move.

[0055] One end of the rotating rod 27 is hingedly connected with a hinged block 28, the outer surface of the hinged block 28 is fixedly connected with the outer surface of the fixed block 17, and the other end of the rotating rod 27 is fixedly installed with a clamping block 29.

[0056] Since the two rotating rods 27 are respectively hinged with the two groups of hinged blocks 28, when the two groups of movable shafts 26 pull the two groups of rotating rods 27, the two groups of rotating rods 27 will rotate in opposite directions with the two groups of hinged blocks 28 as the axis, at this time, the two groups of clamping blocks 29 will rotate in opposite directions under the driving of the two groups of rotating rods 27, and then the two groups of clamping blocks 29 will clamp the bottom support of the unmanned aerial vehicle in the opposite direction rotation.

[0057] The working principle and use process of the utility model:

[0058] First, the operator places the device at the bottom end of the unmanned aerial vehicle, at this time, the bottom support of the unmanned aerial vehicle will be located between the two groups of clamping blocks 29, then the operator starts the motor 18, at this time, the rotating shaft 19 will drive the driving conical gear 20 to rotate, since the outer surface of the driving conical gear 20 is respectively meshed and connected with the outer surface of the two driven conical gears 21, when the driving conical gear 20 rotates, it will drive the two driven conical gears 21 to rotate at the same time, then the two driven conical gears 21 will drive the two long shafts 22 to rotate inside the fixed block 17, at this time, the two screw rods 23 will rotate under the driving of the two driven conical gears 21, since the outer surface of the two screw rods 23 is respectively sleeved with the inner thread of the two movable blocks 24, when the two screw rods 23 rotate, they will drive the two movable blocks 24 to move towards each other, then the two movable blocks 24 will drive the two groups of movable shafts 26 to move through the two groups of moving rods 25, at this time, the two groups of movable shafts 26 will pull the two groups of rotating rods 27 to make the two groups of rotating rods 27 rotate in opposite directions with the two groups of hinged blocks 28 as the axis, at this time, the two groups of clamping blocks 29 will rotate in opposite directions under the driving of the two groups of rotating rods 27, then the two groups of clamping blocks 29 will clamp the bottom support of the unmanned aerial vehicle in the opposite direction rotation, at this time, the device as a whole will be in a connected state with the unmanned aerial vehicle, thereby realizing the function of making the device convenient to install with the unmanned aerial vehicle.

[0059] Then the operator puts the protection rope into the inside of the ring 15 and knots it, so that the protection rope is connected with the ring 15 as a whole, and then the operator starts the air cylinder 13, at this time the bottom end of the air cylinder 13 drives the extrusion block 14 to move downward, at this time the extrusion block 14 will extrude and push the two moving blocks 4 in the downward movement, so that the two moving blocks 4 move along the outer surface of the round rod 2, due to the design of the round rod 2, the movement of the moving block 4 is limited, at this time the two moving blocks 4 will drive the clamping plate 12, the arc block 6 and the stop block 7 to move in opposite directions as a whole, in this process, the two springs 5 will be compressed, then the operator places the hanging 3 between the two moving blocks 4, and then the operator moves the rotating rod 8, so that the rotating rod 8 rotates ninety degrees around the fixed shaft 9, at this time the torsional spring 11 will be deformed in the rotation of the rotating rod 8, then the operator starts the air cylinder 13 again, at this time the extrusion block 14 moves upward, due to the elastic force of the two springs 5, at this time the two moving blocks 4 will move towards each other under the driving of the two springs 5 to reset, then the two clamping plates 12 will clamp the hanging 3 under the driving of the two moving blocks 4 to fix the hanging 3 as a whole, at the same time the two moving blocks 4 will drive the two stop blocks 7 to move towards each other through the two arc blocks 6, when the two ends of the two stop blocks 7 contact, they can block the rotation of the rotating rod 8;

[0060] When the unmanned aerial vehicle drives the hanging 3 to move to the cross arm of the power transmission line tower, the operator starts the air cylinder 13 again, at this time the extrusion block 14 moves downward to make the two moving blocks 4 move in opposite directions as a whole, then the two stop blocks 7 will remove the block of the rotation of the rotating rod 8 in the opposite movement, at this time the rotating rod 8 will rotate in the opposite direction under the driving of the two torsional springs 11, when the rotating rod 8 rotates in the opposite direction by ninety degrees, it will be blocked by the hanging 3, at this time the hanging 3 cooperates with the rotating rod 8 to form a locked state, thereby realizing the function of facilitating the operator to hang the protection rope.
