The proximity photoelectric sensor 6 is used to monitor whether the mounting plate 201 is close or not.

[0027] In practical use, the monitoring equipment base plate 1 is located at the bottom of the monitoring equipment (UAV, reconnaissance aircraft, etc.). When the monitoring equipment is in flight, the optoelectronic pod 2 needs to extend out of the through hole 101 (e.g., Figure 1 As shown), when the equipment needs to be lowered, the remote-controlled servo motor 1002 drives the winch drum 1001 to rotate a set number of times and then stops. As the hoisting rope 12 is retracted, it lifts the base platform 3, thereby retracting the photoelectric pod 2 above the monitoring equipment base plate 1 (as shown). Figure 3 As shown, when the proximity photoelectric sensor 6 detects an object approaching its sensing range, the output signal changes. The controller receives this signal change and actively controls the servo motor 1002 to stop moving, thus preventing damage to the photoelectric pod and the hoisting equipment.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
