Description

Technical Field

[0001] This utility model specifically relates to an inspection drone based on infrared detection, belonging to the field of drone technology. Background Technology

[0002] Infrared detection is a method of detecting the surface of an object by using the principle of infrared radiation. In essence, it scans and records the temperature changes caused by different thermal properties of the surface of the object being inspected. Various infrared detectors have been derived from this technology and are widely used in many fields. This technology is also used in inspection drones.

[0003] A bridge inspection drone frame and a bridge inspection drone are disclosed according to patent application number CN202021209935.8. The bridge inspection drone frame may include an equipment mounting mechanism, a power unit, a collision avoidance mechanism, and a landing gear mechanism. The power unit includes multiple dual-rotor mechanisms, each of which is horizontally connected to the equipment mounting mechanism via an arm. The collision avoidance mechanism includes a collision avoidance ring and multiple collision avoidance struts; one end of each of the multiple collision avoidance struts is horizontally connected to the equipment mounting mechanism, and the other end is connected to the collision avoidance ring, such that the multiple dual-rotor mechanisms are all located inside the collision avoidance ring. The bridge inspection drone frame and bridge inspection drone of this application embodiment can more effectively ensure flight safety when the drone flies under a bridge, and can also better achieve remote visual imaging of the bridge underside.

[0004] The bridge inspection drone frame and the bridge inspection drone in the above patent enable the drone to more effectively ensure flight safety when flying under the bridge, and can also better achieve remote visual imaging of the bridge bottom surface. However, the existing live inspection drones are more complicated to install infrared detectors. Since different models of infrared detectors are required in different situations, the connection positions may be slightly off, resulting in poor applicability and more troublesome use. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing an infrared detection-based inspection drone to achieve the purpose of quickly disassembling different models of infrared detectors. The drone includes a main body, an infrared detector body, and a mounting assembly. A top plate is fixedly connected to the top of the infrared detector body, and the top plate has mounting holes. The mounting assembly includes a mounting plate with a groove inside. Slide plates are slidably connected to both sides of the groove. A threaded rod is rotatably connected through the mounting plate, and the slide plate is threadedly connected to the threaded rod. A cavity is provided inside the slide plate, and an adjustment plate is provided inside the cavity. A first bolt is fixedly connected to the bottom of the adjustment plate, passing through the mounting hole, and a first nut is threadedly connected to the bottom of the first bolt.

[0006] Furthermore, the drone body and the mounting assembly are connected by a connecting assembly, which includes two fixing blocks fixedly connected to the bottom of the drone body. The fixing blocks have a slot in the middle and a groove inside. A second bolt is hinged in the groove, and a second nut is threaded to the bottom of the second bolt. The bottom of the fixing blocks has a limiting groove, and the bottom of the mounting plate has a positioning groove.

[0007] Furthermore, the threaded rod is provided with two sets of opposite threaded structures, the two sliding plates are respectively located on the two sets of opposite threaded structures, and the mounting holes are provided in four sets.

[0008] Furthermore, the cavity is T-shaped, and each cavity is provided with two adjusting plates. The thickness of the adjusting plates is less than the depth of the cavity, and the first bolt penetrates the bottom of the cavity.

[0009] Furthermore, the mounting plate slides within the slot, the positioning groove slides within the limiting groove, and the second bolt is attached to the outer side of the mounting plate.

[0010] Furthermore, the second bolt passes through the limiting groove, the second nut is located below the fixing block, and the diameter of the second nut is greater than the width of the limiting groove. Beneficial effects

[0011] I. This utility model adjusts the distance between the two slide plates by rotating the threaded rod, and then adjusts the position of the two first bolts in each cavity. It can be adjusted according to the position of the four mounting holes on the top plate, and then installed and fixed according to different types of infrared detector bodies. It is simple and convenient to operate and has strong applicability.

[0012] Second, by inserting the positioning groove at the bottom of the mounting component into the limiting groove, the infrared detector body can be removed without disassembling the four first nuts. Only the two second nuts need to be unscrewed, which facilitates the removal of the infrared detector body for inspection and maintenance in the future. Furthermore, the mounting component installed in the fixing block can be fixed by the second bolt, ensuring the stability during infrared detection. Attached Figure Description
