Description

Technical Field

[0001] The utility model relates to the technical field of inspection drones, in particular to a large-scale steel structure appearance inspection drone with an infrared night vision function. Background Art

[0002] The specific applications of drones in the field of power inspection are mainly fine inspection, fixed-point inspection, range inspection and other inspections. Generally, fine inspection requires comprehensive and detailed data collection and inspection. The speed of a single inspection is slow, the speed of fixed-point inspection is moderate, and the speed of range inspection is fast. Therefore, a large steel structure appearance inspection drone with infrared night vision function is needed.

[0003] According to the description of a patrol drone disclosed on the patent website (authorization announcement number: CN 217893211 U), "The utility model provides a patrol drone, which belongs to the field of drone technology. The patrol drone includes a fuselage, one side of the fuselage is integrally formed with an arm, a propeller is rotatably installed on the arm, the bottom of the fuselage is integrally formed with a mounting frame, the mounting frame is fixedly installed with a support foot, the bottom of the fuselage is fixedly installed with a foam board, the bottom of the arm is fixedly installed with a foam board, one end of the fuselage is opened with a first groove, the first groove is provided with a camera, and the first groove is fixedly installed with a waterproof cover. The utility model obtains a patrol drone through the above design. When the drone needs to land on the water, the user needs to control the drone to land until the buoyancy sleeve contacts the water surface. At this time, because the buoyancy of the buoyancy sleeve is not enough to support the drone, the drone will slowly sink. When it sinks to the foam board contacting the water surface, the landing can be completed, so that the drone can land on the water surface to prevent losses caused by the drone falling into the water."

[0004] In response to the above description, the applicant believes that the following problems exist: when the device is in use, the user needs to control the drone to land until the buoyancy sleeve contacts the water surface. At this time, since the buoyancy of the buoyancy sleeve is insufficient to support the drone, the drone will slowly sink. When it sinks to the point where the foam board contacts the water surface, the landing is completed, allowing the drone to land on the water surface. Since the camera of the device can only slide in the slide groove inside the device, the angle of the camera cannot be adjusted, thereby limiting the detection range of the inspection drone.
