[0015] In summary, the present invention includes the following beneficial technical effects: The present invention provides components such as an air supply structure, a baffle, a double-headed sealing tube, an air hole and a movable disk. Before the paddle plate contacts the cable, the air hole on the lower side of the double-headed sealing tube is located below the vertical tube, and the tension spring is at the shortest stretching distance. When the drone moves to the top of the cable and lands downward, the two cables are respectively located below the two through grooves on the same horizontal tube. The cable contacts the paddle plate just above and pushes the paddle plate to rotate upward, pushing the movable bar and the baffle bar to move upward, and the double-headed sealing tube moves upward following the movable bar. When the air hole on the upper side of the double-headed sealing tube enters the box plate, the air hole below enters the vertical tube and is blocked, and the air supply structure inflates the box plate through the three-way pipe, and the gas enters the horizontal tube through the air hole on the upper side and the air permeable structure at the middle position of the double-headed sealing tube.

When the cable shakes, the side wheel rotating structure moves to different positions to limit the cable according to pushing the paddle plates at different positions.

[0016] The present invention provides components such as an air pressure plate, an air box, a friction damping plate and a friction damping wheel. When the double-axis power box drives the two friction damping wheels to rotate through transmission, the friction damping wheel pushes the air pressure plate to move outside the air box through contact with the friction damping plate during rotation, so that the air box is filled with gas. When the shift plate pushes the movable plate upward to drive the push rod to move upward, the friction damping wheel is pushed upward by the support block to separate from the friction damping plate. The air pressure plate pushes the internal gas into the three-way pipe under the action of the elastic connection with the air box, and fills the gas into the cross pipe. After the cable applies pressure to the shift plate, the air box can automatically inflate the three-way pipe.

[0017] The present invention arranges components such as a side rotating wheel, an inner air pipe and a return spring. After air flow is filled into the transverse tube, the air flow first pushes the side rotating wheel to move downward to stretch the return spring, so that the lower end of the side rotating wheel extends below the cable, so that the two side rotating wheels corresponding to the same through slot can limit the two sides of the cable.

[0018] The present invention provides components such as a gear cylinder and an adjusting gear plate. After the side rotating wheel limits the cable, the electric telescopic rod drives the adjusting gear plate to move and engage with the gear cylinder. The rotation of the gear cylinder drives the fan blade structure to rotate half a circle, so that the fan blade structure rotates to the horizontal end. When the fan blade structure continues to rotate, the horizontal force of the chassis is increased, which facilitates the sliding of the chassis on the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is combined with Figure 1-9 The present invention is described in further detail.

[0022] The embodiment of the present invention discloses a power inspection drone. Figure 1 As shown, it includes a chassis body 1 and two supporting side frames 2, the left and right sides of the chassis body 1 are respectively fixed to the upper ends of the two supporting side frames 2, an air supply structure 6 is installed inside the chassis body 1, one end of the air supply structure 6 is fixedly connected with a three-way pipe 5, the front and rear ends of the three-way pipe 5 are fixedly passed through the inner bottom wall of the chassis body 1, the front and rear ends of the three-way pipe 5 are located below the chassis body 1 and are fixedly connected with a crate plate 3, a movable bar 4 is arranged below the crate plate 3, the upper surface of the movable bar 4 is elastically connected to the bottom surface of the chassis body 1, and the movable bar 4 has a tendency to move downward.

[0023] The air supply structure 6 includes an air pressure plate 61 and an air box 62. One end of the air pressure plate 61 is slidably inserted into the interior of the air box 62. The end of the air pressure plate 61 located inside the air box 62 is elastically connected to the inner wall of the air box 62. The end of the air box 62 away from the air pressure plate 61 is fixedly connected to the middle position of the three-way pipe 5. Friction damping plates 63 are arranged inside the chassis 1 and on the front and rear sides of the air box 62. The friction damping plate 63 is fixed to the end of the air pressure plate 61 located outside the air box 62. A friction damping wheel 64 is meshed on the upper surface of the friction damping plate 63. A telescopic plate 65 is rotatably sleeved on the outer surface of the friction damping wheel 64. The telescopic plate 65 is fixed to the chassis 1. The telescopic plate 65 has a tendency to pull the friction damping wheel 64 downward. When the friction damping wheel 64 rotates, it has the effect of pushing the air pressure plate 61 toward the air box 62 through friction with the friction damping plate 63. The tendency of external movement makes the air box 62 filled with gas, and a transmission structure 66 is set on the side where the two friction damping plates 63 are away from each other. A dual-axis power box 67 is installed inside the chassis 1. The two transmission structures 66 are respectively connected to the two output ends of the dual-axis power box 67, and the transmission structure 66 is rotatably connected to the chassis 1. The ends of the two friction damping wheels 64 away from each other are respectively transmission-connected to the two transmission structures 66. The outer surface of the friction damping wheel 64 is rotatably sleeved with a support block 68, and a push rod 69 is fixed to the bottom surface of the support block 68. The chassis 1 is slidably sleeved on the outer surface of the push rod 69, and the lower end of the push rod 69 is fixed to the upper surface of the movable bar 4 located directly below. The movable bar 4 has a tendency to pull the friction damping wheel 64 downward through the push rod 69 and the support block 68, driving the friction damping wheel 64 to apply pressure to the friction damping plate 63.

[0024] The four corners of the chassis 1 are provided with fan blade structures 19, and the four fan blade structures 19 are respectively connected to the two ends of the two transmission structures 66. The transmission structure 66 includes a long shaft 661, two external bevel gears A662 and two external bevel gears B663. The two external bevel gears A662 and the two external bevel gears B663 are both located outside the chassis 1. The two external bevel gears A662 are respectively fixedly sleeved on the two ends of the long shaft 661. The chassis 1 is rotatably sleeved on the outer surface of the long shaft 661. The long shaft 661 is connected to an output end of the dual-axis power box 67. The two external bevel gears A662 are respectively fixedly sleeved on the two ends of the long shaft 661. They are respectively meshed with two external bevel gears B663, and the external bevel gear B663 is fixedly connected to the adjacent fan blade structure 19. The outer ring sides of both ends of the long shaft 661 are coaxially provided with gear cylinders 664, and the gear cylinder 664 is rotatably connected to the outer surface of the chassis body 1, and the other end of the gear cylinder 664 is rotatably connected to the adjacent fan blade structure 19. One end of the long shaft 661 located inside the chassis body 1 is fixedly sleeved with an internal bevel gear A665, and the side of the internal bevel gear A665 close to the axis of the chassis body 1 is meshed with an internal bevel gear B666, and the internal bevel gear B666 is fixedly sleeved on the outer surface of the adjacent friction damping wheel 64.

[0025] Adjusting tooth plates 21 are provided on the left and right sides of the chassis body 1. An electric telescopic rod 22 is fixed to the side of the adjusting tooth plate 21 close to the chassis body 1. The other end of the electric telescopic rod 22 is fixed to the chassis body 1. The upper surfaces of the gear cylinders 664 located on both sides of the chassis body 1 are respectively engaged with the adjacent adjusting tooth plates 21. The electric telescopic rod 22 drives the adjusting tooth plate 21 to move forward and backward. The gear cylinder 664 changes the angle of the fan blade structure 19 by engaging with the adjusting tooth plate 21. When the fan blade structure 19 rotates to a horizontal position, it is convenient to push the chassis body 1 to slide on the cable.

[0026] Two transverse tubes 8 are arranged between the two movable bars 4, and vertical tubes 9 are fixedly penetrated at the middle position and both ends of the upper surface of the transverse tube 8, the interior of the vertical tube 9 is connected to the interior of the transverse tube 8, and the outer surface of the transverse tube 8 is provided with two vertically penetrating grooves 10, and the two grooves 10 are alternately distributed with the three vertical tubes 9. Two movable disks 11 are slidably inserted on the outer surface of the transverse tube 8 and inside each groove 10, and telescopic gas hoods 12 are fixed on the sides away from each other of the two movable disks 11 connected to the same groove 10, and the other end of the telescopic gas hood 12 is fixed to the transverse tube 8, and the telescopic gas hood 12 ensures that the gas in the transverse tube 8 will not leak from the groove 10. The transverse tube 8 is located inside the telescopic gas hood 12, and tension springs 13 are fixed on the sides away from each other of the two movable disks 11 connected to the same groove 10, and the other end of the tension spring 13 is fixed to the interior of the transverse tube 8, and the tension spring 13 has a tendency to contract.

[0027] A side wheel rotating structure 7 is installed on a side of the movable plate 11 close to the axis of the chassis 1 .

[0028] The side wheel rotation structure 7 includes a side rotating wheel 71 and an inner air pipe 72. The interior of the movable disk 11 is in a cavity shape. The side of the movable disk 11 connected to the tension spring 13 is open. The side rotating wheel 71 is rotatably sleeved on the lower end of the inner air pipe 72. A return spring 73 is fixed inside the inner air pipe 72. The elasticity of the return spring 73 is less than the elasticity of the tension spring 13. The upper end of the side rotating wheel 71 is rotatably inserted with a distance ring 74. The distance ring 74 is slidably sleeved on the outer surface of the inner air pipe 72. The distance ring 74 prevents the side rotating wheel from rotating. The wheel 71 is separated from the inner air pipe 72. When gas is filled into the transverse tube 8, the gas first pushes the side rotating wheel 71 to stretch the return spring 73, and then pushes the movable disk 11 to stretch the tension spring 13. The lower end of the return spring 73 is rotated and inserted into the outer surface of the side rotating wheel 71. The end of the inner air pipe 72 located above the side rotating wheel 71 is fixedly connected to the adjacent movable disk 11. When the transverse tube 8 is not filled with gas, the side rotating wheel 71 is completely covered on the surface of the inner air pipe 72 to prevent it from affecting the landing of the chassis 1.

[0029] The upper end of the vertical tube 9 is fixedly connected to the bottom surface of the crate board 3 located directly above, and a double-headed sealing tube 14 is slidably inserted inside the vertical tube 9. The middle position of the double-headed sealing tube 14 is a breathable structure. The double-headed sealing tube 14 is located at the upper and lower ends of the breathable structure and is provided with air holes 15. The lower end of the double-headed sealing tube 14 is fixed to the movable bar 4. In the initial state of the movable bar 4, the lower air hole 15 is located below the vertical tube 9. At this time, the vertical tube 9 blocks the air hole 15 on the upper side, so that there is no large air pressure in the cross tube 8, so that the tension spring 13 can be in a contracted state. A shaft rod 16 is arranged below the cross tube 8, and both ends of the shaft rod 16 are fixed to the chassis body 1. A plurality of baffles 17 are arranged below each through groove 10, and the baffles 17 are elastically connected to the bottom surface of the chassis body 1. A dial plate 18 is arranged below each baffle 17, and the dial plate 18 elastically rotates on the outer surface of the adjacent shaft rod 16. Multiple square baffles 17 of equal number and distance are distributed below the two through grooves 10, and the two cross tubes 8 are arranged in parallel. The baffles 17 rising upward on the cable limit the final position of the movable disk 11. The end of the paddle plate 18 away from the shaft 16 is rotatably connected to the force wheel 20, and the center ring position of the force wheel 20 is a V-shaped ring structure. The cable applies thrust to the paddle plate 18 through the force wheel 20. When the chassis body 1 moves relative to the cable, the force wheel 20 rotates to reduce the resistance during movement and reduce the wear on the cable. The V-shaped force wheel 20 can effectively prevent separation from the cable. A one-way air intake valve is installed on the upper surface of the crate plate 3. When the air pressure plate 61 moves toward the outside of the air box 62, the air box 62 can draw air into the inside through the one-way air intake valve. At the same time, the air flow can only flow in one direction in the one-way air intake valve, and the gas in the crate plate 3 cannot be discharged from the one-way air intake valve.

[0030] The implementation principle of one embodiment of the present invention is as follows: the double-axis power box 67 drives the fan blade structure 19 to rotate through the long shaft 661, the external bevel gear A662 and the external bevel gear B663. Before the paddle plate 18 is pushed by the cable, the movable bar 4 elastically connected to the chassis body 1 has a tendency to pull the push rod 69 to move downward, so that the friction damping wheel 64 applies pressure to the friction damping plate 63. The internal bevel gear A665 drives the friction damping wheel 64 to rotate by meshing with the internal bevel gear B666. During the rotation of the friction damping wheel 64, the air pressure plate 61 is pushed to move to the outside of the air box 62 by contacting the friction damping plate 63, so that the air box 62 is filled with gas. Before the paddle plate 18 is not in contact with the cable, the air hole on the lower side of the double-head sealing tube 14 is located below the vertical tube 9, and the tension spring 13 is at the shortest stretching distance. When the drone moves to the top of the cable and lands downward, the two cables are respectively located at two ends on the same horizontal tube 8. The cable contacts the dial plate 18 above and pushes the dial plate 18 to rotate upward, pushing the movable bar 4 and the stop bar 17 to move upward. The double-headed sealing tube 14 moves upward with the movable bar 4. When the air hole on the upper side of the double-headed sealing tube 14 enters the crate plate 3, the air hole 15 below enters the vertical tube 9 and is blocked. The air supply structure 6 inflates the crate plate 3 through the three-way pipe 5, and the gas enters the horizontal tube 8 through the air hole 15 on the upper side and the air permeable structure at the middle position of the double-headed sealing tube 14. The airflow first pushes the side rotating wheel 71 to move downward and stretch the return spring 73, so that the lower end of the side rotating wheel 71 extends to the bottom of the cable. The airflow pushes the movable disk 11 to stretch the tension spring 13 to drive the side rotating wheel 71 close to the cable. The four side rotating wheels 71 on the horizontal tube 8 limit the two sides of the two cables respectively. When the cable is shaking, it can rotate the dial plates 18 at different positions to limit the cable at different positions below the horizontal tube 8.

[0031] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
