[0033] Working principle: First, the rodless cylinder 20 is turned on, and the movable end of the rodless cylinder 20 can be used to push the first movable cylinder 23 to move, thereby driving the second electric cylinder 24 to move forward to a suitable position. When the second electric cylinder 24 needs to move backward, the first movable cylinder 23 is pushed backward through manual adjustment. The second electric cylinder 24 is turned on to extend the output shaft of the second electric cylinder 24, and the position of the second movable cylinder 25, the infrared ranging sensor 26 and the sliding rod 27 can be adjusted;

[0034] The slide bar 27 slides along the inner wall of the first chute 8. When the slide bar 27 moves between the upper chute 9 and the lower chute 10, the push-in mechanism is activated to push the second movable cylinder 25 upward. Specifically, the first electric cylinder 12 is activated to cause the lifting plate 13 to drive the protrusion 14 to move upward, thereby moving the second movable cylinder 25 upward, thereby causing the slide bar 27 to move upward to the inner wall of the second chute 30.

[0035] Then, the second electric cylinder 24 is turned on so that the output shaft of the second electric cylinder 24 extends, and the slide rod 27 is pushed into the rightmost side of the inner wall of the second slide groove 30, so that the slide rod 27 can be fixed at multiple measuring points.

Distance measurement at these points can avoid interference from sunlight and other light, and the position of the sliding rod 27 can also be adjusted according to the time of day. For example, in the morning, the sliding rod 27 is adjusted to a suitable position on the inner wall of the first chute 8, and at noon, the sliding rod 27 is adjusted to the rightmost position on the inner wall of the second chute 30, so that the position of the infrared ranging sensor 26 can be quickly adjusted.

[0037] In addition, the acceleration sensor 32 is turned on to monitor the angle of the sealed steel plate 4 when it rotates, which can be used for auxiliary monitoring. The acceleration sensor 32 is electrically connected to the controller 16. When the acceleration sensor 32 detects an abnormality, the controller 16 will turn on the alarm 17 to alarm, and the controller 16 will also transmit the abnormal signal to the remote server through the wireless transceiver 18;

[0038] It should be noted that the infrared distance measuring sensor 26 measures distance by emitting infrared rays onto the measuring plate 7 .
