Description

Technical Field

[0001] The utility model relates to the technical field of electric power inspection, in particular to a laser point cloud acquisition device used for electric power inspection. Background Art

[0002] Traditional power inspections mainly rely on manual inspections. Inspectors use their eyes, ears, noses, and hands to analyze and judge to discover equipment anomalies. However, this method has problems such as high labor costs, low efficiency, and easy omissions. Drones equipped with lidar can fly along power lines, thereby enabling high-efficiency and low-cost power inspections. Existing drone power inspection devices include a drone body and an inspection equipment body. During inspections, the inspection equipment body needs to be hung on the lower side of the drone, usually connected by a hanging rope and a hook, which will cause the inspection equipment body to become unstable. The inspection equipment is easily blown by the wind, causing the inspection equipment to shake, resulting in blurred images of the inspection equipment, affecting the imaging effect.

[0003] To this end, the utility model provides a laser point cloud acquisition device for power inspection. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a laser point cloud acquisition device for power inspection, comprising a collection box 1 installed on the lower side of a drone, wherein the collection box 1 is equipped with a laser radar 2, a camera 3, a main control board 5 and an inertial navigation system 4, an anti-collision buffer structure is installed on the lower side of the collection box 1, an anti-fog heating structure is installed on one side of the collection box 1, a connector 9 is fixed on the upper side of the collection box 1, a fixing plate 12 is fixed on the lower side of the drone, a top plate 13 is installed on the lower side of the fixing plate 12, a connecting structure is installed between the fixing plate 12 and the top plate 13, and the top plate 13 is threadedly matched with the connector 9.

[0022] In this embodiment, the camera 3 includes a lens, which is located on the relatively outer side of the acquisition box 1. The lens corresponds to the anti-fog heating structure. The anti-fog heating structure includes a resistor coil 6, which is located around the lens.

[0023] Specifically, the camera 3 can be used to take pictures of electric wires, poles, insulators, and surrounding vegetation and buildings, so that color processing can be performed and the sound field color point cloud can be displayed intuitively. The temperature of the lens surface can be increased by the heating resistor coil 6 to prevent the lens surface from fogging and improve the clarity of the shooting.

[0024] The anti-collision buffer structure includes a buffer seat 7 , and a spring 8 is fixed between the buffer seat 7 and the collection box 1 .

[0025] Specifically, the collection box 1 can be buffered by the buffer seat 7 to prevent the collection box 1 from directly colliding with the ground. When the drone lands, the buffer seat 7 contacts the ground, thereby compressing the spring 8, thereby buffering the collection box 1 and preventing the collection box 1 from being damaged.

[0026] A threaded head 10 is fixed on the upper side of the connecting head 9 , and a threaded sleeve 11 is fixed on the lower side of the top plate 13 . The threaded sleeve 11 corresponds to the threaded head 10 .

[0027] Specifically, when the collection box 1 needs to be installed with the drone, the collection box 1 can be fixed by screwing it together with the threaded head 10 and the threaded sleeve 11, thereby preventing the collection box 1 from shaking due to wind, and the collection box 1 can remain relatively still with the drone.

[0028] The connecting structure includes two first connecting rods 14 and two second connecting rods 15. The adjacent first connecting rods 14 are rotatably connected to the second connecting rods 15. The first connecting rod 14 is rotatably connected to the top plate 13. The fixed plate 12 is rotatably connected to the second connecting rod 15. A rotating shaft is installed between the first connecting rod 14 and the top plate 13, between the fixed plate 12 and the second connecting rod 15, and between the first connecting rod 14 and the second connecting rod 15. One end of the rotating shaft is threaded with a nut 16.

[0029] Specifically, the distance between the fixing plate 12 and the top plate 13 can be adjusted by rotating the first connecting rod 14 and the second connecting rod 15, thereby adjusting the fixed position of the collection box 1 to prevent the collection box 1 from being blocked by the drone. The first connecting rod 14 and the second connecting rod 15 can also be squeezed by rotating the nut 16 to prevent the first connecting rod 14 and the second connecting rod 15 from rotating, thereby fixing the position of the collection box 1.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
