Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle autonomous inspection devices, in particular to an unmanned aerial vehicle autonomous inspection system device. Background Art

[0002] Drone inspection is a method of remote monitoring and inspection using drone technology. This method has been widely used in many fields, including electricity, oil, natural gas, transportation, agriculture, etc. In cold areas in winter, due to the low temperature and the fact that most power lines are installed at high altitudes, drones are generally used in winter to conduct autonomous inspections and de-icing of power transmission lines to avoid excessive ice on the wires, which may affect the transmission of electricity.

[0003] Existing drone inspection and de-icing methods generally involve hanging an iron rod under the drone via a connecting rope, which is then lifted and moved near the power lines by the drone. The drone's swing causes the iron rod to collide with the ice on the power lines, thereby breaking the ice on the iron rod. However, when the drone is moving near the power lines with the iron rod hung on it, the connecting rope may become entangled in the power lines due to the shaking of the iron rod or the movement of the drone, thereby causing damage to the drone. In addition, the continuous reciprocating shaking of the drone will also increase the load on the drone's internal mechanism, reducing the drone's service life. Utility Model Content

[0020] In order to make the technical solution and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The utility model provides a technical solution: Figure 1 - Figure 4 The utility model discloses an autonomous inspection system device of a UAV, including a UAV 1, a camera 2 is fixedly mounted on the front end of the bottom side of the UAV 1 through a bracket, and the camera 2 is arranged in an inclined state, a deicing assembly 3 is arranged at the center position of the bottom side of the UAV 1, and the deicing assembly 3 includes a knocking plate 31, a driving mechanism 32 is arranged on the knocking plate 31, and a connecting mechanism 33 is arranged on the top side of the driving mechanism 32.

[0022] In this embodiment, when the improved drone 1 autonomous inspection system device is used, the operator controls the drone 1 and the camera 2 to cooperate with each other to conduct autonomous inspections on the wires, thereby determining the thickness of the ice layer on the wires. When the knocking plate 31 and the wires collide with each other, the inclination of the knocking plate 31 can be automatically adjusted through the connecting mechanism 33, so that the wires slide off the knocking plate 31 along the outer wall of the knocking plate 31, and finally the knocking plate 31 will not hang on the wires.

[0023] When the device detects that the ice layer on the wire is thick, the drone 1 moves the knocking plate 31 to the top of the wire, and then the driving mechanism 32 drives the knocking plate 31 to move downward quickly and collide with the ice layer on the wire, thereby breaking the ice layer on the wire, and at the same time, the broken ice layer is shaken off by the vibration of the wire.

[0024] In a further preferred embodiment of the present invention, Figure 3 As shown, the driving mechanism 32 includes a piston plate 322, a storage groove 321 is opened at the center of the top side of the knocking plate 31, and the piston plate 322 is slidably installed in the storage groove 321, the cross-section of the top opening of the storage groove 321 is square, and a square rod 323 is fixedly installed on the top side of the piston plate 322, and the top of the square rod 323 extends to the outside of the storage groove 321 and contacts the inner wall of the top opening of the storage groove 321;

[0025] In this embodiment, during the downward movement of the knocking plate 31, due to the mutual interference between the square rod 323 and the inner wall of the top opening of the storage groove 321, the knocking plate 31 moves in a vertical linear trajectory, thereby preventing the knocking plate 31 from colliding with the ice layer in an inclined state and affecting the knocking plate 31's breaking effect on the ice layer.

[0026] In a further preferred embodiment of the present invention, Figure 1 - Figure 4 As shown, the connection mechanism 33 includes a base 331, which is fixedly mounted at the center of the bottom side of the drone 1 by bolts, and a ball 332 is fixedly mounted on the top of the square rod 323, and the top of the ball 332 is inserted into the base 331 and rotatably connected to the base 331, and both ends of the knocking plate 31 are arranged in an arc shape;

[0027] In the present embodiment, during the movement of the drone 1, the knocking plate 31 can be driven to move together, and when the knocking plate 31 touches the ice layer of the electric wire, the angle of the knocking plate 31 can be adaptively adjusted by the rotation of the ball 332 located in the base 331, so that the electric wire slides off the knocking plate 31 along the side wall of the knocking plate 31, and finally the knocking plate 31 will not be hung on the electric wire, thereby preventing the knocking plate 31 from hanging on the electric wire and exerting pulling force on the drone 1, affecting the movement of the drone 1 and causing damage to the drone 1.

[0028] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, two air pumps 324 are provided on the outer peripheral side of the square rod 323, and each air pump 324 is fixedly connected to the top side of the knocking plate 31. Two air inlet holes 325 are provided at positions corresponding to the storage tank 321 in the knocking plate 31, and the interior of each air inlet hole 325 is communicated with the interior of the storage tank 321. The exhaust end of the air pump 324 is inserted into the air inlet of the corresponding air inlet hole 325 and fixedly connected to the inner wall of the air inlet of the corresponding air inlet hole 325.

[0029] In the present embodiment, after the knocking plate 31 is moved above the ice layer, the air pump 324 is started for a specific period of time to extract external gas, and then the air pressure in the bottom of the storage tank 321 is quickly stored at the air inlet hole 325, and gradually increases, thereby pushing the knocking plate 31 downward, so that the conical bottom end of the knocking plate 31 quickly collides with the ice layer on the wire, thereby breaking the ice layer on the wire, and at the same time, the broken ice layer is shaken off by the vibration of the wire, and the collision force between the knocking plate 31 and the ice layer can be adjusted by the air injection efficiency of the air pump 324, thereby reducing the energy consumption efficiency of the air pump 324.

[0030] In a further preferred embodiment of the present invention, Figure 3 As shown, a first spring 326 is provided between the top side of the piston plate 322 and the inner wall of the storage groove 321, and the two ends of the first spring 326 are respectively fixedly connected to the piston plate 322 and the inner wall of the storage groove 321, a soft ring 333 is provided on the outer peripheral side fixed sleeve of the bottom of the ball 332, and the inner ring wall of the soft ring 333 is slidably connected to the outer peripheral wall of the top of the square rod 323, and the interior of the soft ring 333 is hollow and filled with air;

[0031] In this embodiment, after the collision between the knocking plate 31 and the ice layer is completed, the air pump 324 stops running, and due to the push of the knocking plate 31 by the first spring 326, the knocking plate 31 quickly moves up and resets. After the knocking plate 31 and the soft ring 333 are released from each other, the soft ring 333 pushes the knocking plate 31 during deformation, so that the knocking plate 31 quickly stops moving up, thereby performing the buffer groove operation when the knocking plate 31 is reset, avoiding repeated collisions between the knocking plate 31 and the spherical block to affect the use of the device.

[0032] In a further preferred embodiment of the present invention, Figure 3 and Figure 4As shown, the piston plate 322, the square rod 323 and the ball 332 are provided with an exhaust hole 327, a circular groove 328 is provided at the center of the top side of the base 331, and the interior of the circular groove 328 is communicated with the interior of the exhaust hole 327, a second spring 334 is provided on the top side of the ball 332, and the two ends of the second spring 334 are respectively fixedly connected to the ball 332 and the inner wall of the circular groove 328, a plurality of support blocks 329 are fixedly installed on the top side of the base 331, and the plurality of support blocks 329 are arranged in a circle on the outer peripheral side of the circular groove 328, and the top side of the support blocks 329 is in contact with the bottom side of the UAV 1;

[0033] In this embodiment, after the knocking plate 31 is no longer in contact with the wire, the second spring 326 quickly pulls the ball 332 to rotate in the opposite direction so that the square rod 323 returns to the vertical state and drives the knocking plate 31 to reset;

[0034] When the first spring 326 pulls the piston plate 322 to reset, the gas in the storage tank 321 passes through the exhaust hole 327 and the circular groove 328 and is discharged from the gap between the base 331 support block 329 and the outer shell of the drone 1, thereby avoiding the occurrence of high pressure or negative pressure chamber in the storage tank 321 when the piston plate 322 moves, which affects the use of the device.

[0035] Working principle: When the improved UAV 1 autonomous inspection system is used, the operator controls the UAV 1 to move near the electric wire, thereby driving the camera 2 to shoot the electric wire. The program in the control host of the UAV 1 determines the thickness of the ice layer on the electric wire through the photographed electric wire image;

[0036] During the movement of the drone 1, the knocking plate 31 can be driven to move together, and when the knocking plate 31 touches the ice layer of the electric wire, the angle of the knocking plate 31 can be adaptively adjusted by the rotation of the ball bearing 332 located in the base 331, so that the electric wire slides off the knocking plate 31 along the side wall of the knocking plate 31, and finally the knocking plate 31 will not be hung on the electric wire, and after the knocking plate 31 does not conflict with the electric wire, the second spring 326 quickly pulls the ball bearing 332 to rotate in the opposite direction so that the square rod 323 returns to the vertical state, and drives the knocking plate 31 to reset;

[0037] When the ice layer on the wire is detected to be too thick, the drone 1 moves the knocking plate 31 to the top of the wire, and then the air pump 324 is started for a specific time to extract external gas, and then part of the gas injected into the storage tank 321 passes through the exhaust hole 327 and the circular groove 328 and is discharged from the gap between the base 331 support block 329 and the shell of the drone 1. Since the amount of gas discharged from the exhaust hole 327 is limited, the air pressure at the bottom of the storage tank 321 gradually increases, thereby pushing the knocking plate 31 downward, so that the knocking plate 31 is pushed downward. The conical bottom end of the striking plate 31 quickly collides with the ice layer on the wire, thereby breaking the ice layer on the wire, and at the same time, the broken ice layer is shaken off by the vibration of the wire. After the air pump 324 stops running, the striking plate 31 is pushed by the first spring 326, and the striking plate 31 quickly moves up and resets. After the striking plate 31 and the soft ring 333 contact each other, the soft ring 333 pushes the striking plate 31 when it is deformed, so that the striking plate 31 quickly stops moving up. According to the above repeated operations, the wires can be continuously inspected and the ice layer on the wires can be removed.

[0038] During the downward movement of the knocking plate 31 , due to the mutual interference between the square rod 323 and the inner wall of the top opening of the storage groove 321 , the knocking plate 31 moves in a vertical linear trajectory.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
