[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. When a person needs to enter the main body of the machine room during use, the person moves to a position between the infrared emitting device and the infrared receiving device, so that the infrared rays cannot be normally received by the infrared receiving device. At this time, the motor starts to drive the screw to rotate, thereby causing the slider to move inside the slide groove, driving the baffle to move and separate, until the person enters the main body of the machine room. At this time, the infrared receiving device receives the infrared rays again, and the motor drives the screw to rotate in the opposite direction, so that the baffle returns to the closed state, so that rat prevention work is performed during inspection, and people do not need to cross the baffle when entering and leaving, preventing people from falling, and there is no need to manually open the baffle, which greatly improves the convenience of use of the device; 2. When in use, the present invention sets the timing switch time to the inspection interval time, and presses the reset switch at the end of the inspection to reset the timing switch. In this way, if the inspection is not carried out in time, the alarm will start the alarm to ensure the normal progress of the inspection work. BRIEF DESCRIPTION OF THE DRAWINGS
