Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to a smart power grid inspection unmanned aerial vehicle. Background Art

[0002] Unmanned aircraft, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. Drones are actually a general term for unmanned aircraft. Compared with manned aircraft, drones are small in size, low in cost, and easy to use.

[0003] In order to ensure the stable operation of the power grid line system, the smart grid needs to regularly inspect the power grid lines and line connections. However, since most power grid lines are located at high altitudes, manual inspections are inconvenient and there are certain risks. Therefore, inspections are mostly completed by drones. Traditional drones need to be equipped with corresponding camera equipment during inspections to capture and shoot the power grid line images, so as to understand the line connection status. The camera structure on the drone has poor adjustability. Generally, the flight angle is adjusted by the drone so that the camera can face the power grid position. Usually, the power grid to be inspected is mostly in a complex position of the power grid lines. At this time, the drone changes the camera angle back and forth, which can easily cause the drone rotor to touch the line, resulting in a malfunction. In severe cases, it will damage the power grid line and cause a lot of economic losses.

[0004] Based on this, a smart grid inspection drone is proposed. Summary of the invention

[0005] The purpose of the present invention is to propose a smart grid inspection drone in order to solve the above-mentioned problems.

The screw can be rotated and adjusted, so that after the adjustment motor rotates one circle, the length of the rack displacement is different, that is, the adjustment accuracy of the camera rotation angle is different by relying on the screw adjustment, and the structure is adjustable.

A rotating mechanism for driving the camera 26 to rotate is connected to the motor hoop 14. The camera 26 is rotated by the rotating mechanism, so as to capture images of various angles on the power grid instead of controlling the rotation of the drone.

[0030] Specifically, Figure 5 As shown, a slide bar 9 is connected to the inner side of the shell 1, and a slide clamp 20 is slidably connected to the slide bar 9. The slide clamp 20 is connected to one side of the slide rail 10. By setting the slide clamp 20 to slide with the slide bar 9, the stability of the lifting and lowering structure of the slide rail 10 is improved, wherein two slide clamps 20 are fixedly connected to one side of the slide rail 10.

[0031] Specifically, Figure 5 As shown, the telescopic end of the telescopic cylinder 8 is connected with a sleeve 19, and the sleeve 19 is sleeved on the slide rod 6. By setting the sleeve 19 structure, the wear of the structural transmission between the telescopic end of the telescopic cylinder 8 and the slide rod 6 can be reduced, and the slide rod 6 can be ensured to be always in a horizontal state, thereby correspondingly improving the stability of the structural movement of the slide rod 6.

[0032] Specifically, Figure 2 As shown, the telescopic cylinder 8 is connected to a cylinder sleeve 7, and a rod-like structure is connected to the outer side of the cylinder sleeve 7. The cylinder sleeve 7 is rotatably connected to one side of the shell 1 through the rod-like structure. The cylinder sleeve 7 is used to ensure the firmness of the connection of the telescopic cylinder 8 structure. When the telescopic cylinder 8 is extended or retracted, the telescopic cylinder 8 structure will also rotate, and the axis of rotation is the rod-like structure, wherein a circular hole groove is opened on the shell 1, and the rod-like structure is rotatably connected to the circular hole groove.

[0033] Specifically, Figure 4 and Figure 5 As shown, the rotating mechanism includes an adjusting motor 15, and a traction shaft 27 is rotatably connected to the outer side of the adjusting motor 15. A limiting bar frame 17 is connected to the connecting frame 11. The limiting bar frame 17 structure is horizontally arranged on one side of the gear 34 structure, wherein the cross-section of the limiting bar frame 17 is "U"-shaped, and this structure can well limit the rack 29. The rack 29 is slidably connected to the limiting bar frame 17, and a spring is connected to one end of the rack 29 and one end of the limiting bar frame 17. One end of the rack 29 is connected to the traction shaft 27 through a traction rope 31, and the spring structure is sleeved on the outer side of the traction rope 31, wherein the upper and lower surfaces of the limiting bar frame 17 are provided with grooves, and the upper and lower sides of the rack 29 are slidably connected to the groove, and the groove is set to avoid separation between the rack 29 and the limiting bar frame 17, wherein the toothed side of the rack 29 faces the gear 34 side.

[0034] Specifically, Figure 4 As shown, the output end of the adjusting motor 15 is connected to a solenoid 25, and the solenoid 25 and the output end of the adjusting motor 15 are perpendicular to each other, and the inner wall of the solenoid 25 is provided with a thread, and the solenoid 25 is threadedly connected to a screw rod 16, and a limiting tube 24 is sleeved on the outer side of the screw rod 16, and the screw rod 16 and the limiting tube 24 are rotatably connected, and the inner wall of the limiting tube 24 is not provided with a thread, and a traction shaft 27 is fixedly connected to the outer side of the limiting tube 24, and the traction shaft 27 and the adjusting motor 15 are parallel to each other, and a toothed disk 28 is connected to one end of the screw rod 16, and the toothed disk 28 is provided to facilitate the operator to rotate the screw rod 16, wherein a limiting ring is provided on one side of the limiting tube 24, and the limiting ring is fixedly connected to the screw rod 16, and the positioning of the limiting tube 24 is completed by the limiting ring and the toothed disk 28, so that the limiting tube 24 is always connected to one end of the screw rod 16.

[0035] Specifically, Figure 4 As shown, the output end of the adjusting motor 15 is connected to a connecting strip 23, and the connecting strip 23 is rotatably connected to a connecting strip 1 22, and the connecting strip 1 22 is rotatably connected to the outside of the limiting tube 24. By arranging the connecting strip 1 22 and the connecting strip 2 23, it is ensured that the traction shaft 27 and the output end of the adjusting motor 15 remain parallel to each other, thereby improving the rotation stability of the screw rod 16 structure, wherein the connecting strip 23 and the output end of the adjusting motor 15 are fixedly connected.

[0036] Specifically, Figure 4 As shown, one end of the limiting bar frame 17 is connected to a guide wheel 30, and two guide wheels 30 are provided. The traction rope 31 is provided between the two guide wheels 30. By providing the guide wheel 30, the traction rope 31 located in the limiting bar frame 17 is always in the middle position of the structure, and the setting of the guide wheel 30 structure can also avoid serious structural wear when the traction rope 31 is transmitted, thereby improving the durability of the traction rope 31 structure. The spring structure is provided to facilitate the resetting of the rack 29 structure.

[0037] In summary, the smart power grid inspection drone provided in this embodiment controls the drone to take off and move to the inspection height when it is necessary to inspect the power grid. The operator needs to control the telescopic cylinder 8 to retract. At this time, the sleeve 19 connected to the telescopic end of the telescopic cylinder 8 pulls the slide bar 6 to start sliding along the L-shaped groove 5. When the slide bar 6 drops in height, the slide rail 10 is driven to drop in height synchronously. At this time, the height of the adjusting motor 15 and the camera 26 drops, and the lower end of the camera 26 is exposed to the external environment. Since the camera 26 is not blocked by the shell 1 on all sides, the field of view of the camera 26 is wider, which improves the inspection accuracy. The telescopic cylinder 8 continues to retract. At this time, the slide bar 6 enters the horizontal part of the L-shaped groove 5. At this time, the height of the slide rail 10 remains unchanged, and the slider 33 structure starts to slide along the slide rail 1 0 slides, because the connecting piece 21 connected to one side of the slider 33 is an integrated structure with the adjusting motor 15, at this time, the adjusting motor 15 continues to shrink as the telescopic cylinder 8, and the adjusting motor 15 structure begins to move away from the camera 26 structure, and the rack 29 structure is pulled by the traction shaft 27 to move until the telescopic cylinder 8 is completely contracted. At this time, the rack 29 structure and the gear 34 enter a meshing state, and the operator can control the adjusting motor 15 to rotate, and use the traction shaft 27 to pull the traction rope 31 to move, so that the rack 29 and the gear 34 cooperate with each other, thereby controlling the gear 34 to rotate, thereby driving the camera 26 to change the direction angle, so that the camera 26 is driven to deflect without the need to control the drone to deflect, and the inspection of various positions of the power grid is completed.

[0038] By setting the screw 16, when the adjusting motor 15 rotates, the output end of the adjusting motor 15 drives the screw 16 to rotate, and the distance between the limiting tube 24 connected to the screw 16 and the rotation axis is variable, and the distance can be adjusted by rotating the toothed disc 28 structure. When the limiting tube 24 is farther away from the output end of the adjusting motor 15, the screw 16 rotates a fixed angle to cooperate with the traction shaft 27 to pull the rack 29 to move a farther distance, which is converted into a faster rotation speed of the camera 26. The effect of quickly adjusting the camera 26 can be achieved by adjusting the limiting tube 24 away from the screw tube 25 structure. On the contrary, when the distance between the limiting tube 24 and the screw tube 25 becomes smaller, the rotation angle of the camera 26 can be changed slowly by adjusting the rotation of the motor 15, that is, the accuracy of the camera 26 shooting picture during inspection is improved. Therefore, in the actual application of the drone, the adjustment of the camera 26 shooting requirements can be completed by rotating the toothed disc 28.

[0039] Through the drone, the height of the camera 26 can be lowered relative to the top plate 2 during inspection. At this time, the center of gravity of the overall structure of the drone drops, which improves the stability of the structural movement during the drone inspection. During the inspection, the drone can remain stationary while the orientation angle of the camera 26 changes. The operator can adjust the angle of the camera 26 according to the image captured by the camera 26, thereby reducing the probability of the rotor 3 contacting the line due to the drone shuttling back and forth between power grids, thereby improving the safety of the operation. When the drone completes the inspection, the internal structure of the drone is reset by controlling the extension of the telescopic cylinder 8. At this time, the camera 26 enters the shell 1, which can provide good protection for the camera 26, thereby correspondingly improving the durability of the drone camera 26 structure.
