[0028] In a preferred embodiment, the threads at both ends of the bidirectional threaded rod 702 are in opposite directions, and the output shaft of the first motor 703 is connected to one end of the bidirectional threaded rod 702.

[0029] It should be noted here that the first motor 703 can drive the bidirectional threaded rod 702 to rotate.

[0030] Working principle: The second searchlight 803, the second infrared thermal imager 903 and the first motor 703 are all connected to the slip ring rotor on the conductive slip ring 12 through wires;

[0031] The mounting bracket 1 can be installed on the bottom of the helicopter. The first searchlight 4 and the first infrared thermal imager 5 illuminate and conduct infrared observation of the area directly below the helicopter. The second motor 1101 can drive the gear 1102 to rotate, which in turn drives the gear ring 10 and the rotating tube 6 to rotate, which in turn drives the second searchlight 803 and the second infrared thermal imager 903 to rotate, performing cyclic illumination and infrared scanning observation of the outer perimeter of the area directly below the helicopter, thus expanding the search and rescue range. During this process, the first motor 703 can also drive the bidirectional threaded rod 702 to rotate, causing the two sliders 704 to move closer to each other. Then, the two connecting rods 705 push the first fixing plate 802 and the second fixing plate 902 to open outward, thereby adjusting the angle of the second searchlight 803 and the second infrared thermal imager 903, expanding the scanning range, further expanding the search and rescue range and improving search and rescue efficiency.
