A side stop unit 55 is hinged at the edge of the base plate 1, and the lower end of the driven unit 54 is fixedly bolted to the side wall of the side stop unit 55.

[0033] The monitoring unit 53 includes a rectangular box 531, and the end of the "Y"-shaped bracket 51 away from the lifting block 44 is fixedly connected to the rectangular box 531, and an electric control pressure rod 532 is fixedly installed on the side wall of the rectangular box 531 near the "Y"-shaped bracket 51. A pressure spring 533 is sleeved on the outer side of the electric control pressure rod 532, and the length of the pressure spring 533 is greater than the length of the electric control pressure rod 532. An alarm light 534 is installed on the upper end of the rectangular box 531, and the alarm light 534 is electrically connected to the electric control pressure rod 532. A feedback rod 535 is arranged through the side wall of the rectangular box 531 away from the "Y"-shaped bracket 51, one end of the feedback rod 535 is in contact with the pressure spring 533, and the other end is fixedly connected to a pressure collecting plate 536, and the side wall of the pressure collecting plate 536 is evenly provided with "L"-shaped rods 537, and the end of the "L"-shaped rod 537 away from the pressure collecting plate 536 is fixedly connected to a pressure plate 538.

[0034] A transverse plate 5351 is fixedly connected to the middle of the two feedback rods 535 , and a tooth plate 5352 is fixedly installed to the middle of the lower end surface of the transverse plate 5351 .

[0035] The driven unit 54 includes a side plate 541, which is symmetrically installed on the side wall of the rectangular box 531, a rotating shaft 542 is rotatably installed on the side wall opposite to the lower end of the side plate 541, a driving gear 543 is fixedly installed in the middle of the rotating shaft 542, a wire wheel 544 is fixedly installed near the end of the rotating shaft 542, a traction rope 545 is wound around the wire wheel 544, and the lower end of the traction rope 545 is fixedly connected to the side stop unit 55.

[0036] The side baffle unit 55 includes a first side baffle 551, and the first side baffle 551 is hinged at the edge of the bottom plate 1 close to the monitoring unit 53. The first side baffle 551 is a hollow structure and a plurality of No. 2 electric push rods 554 are arranged at the bottom. The upper end of the No. 2 electric push rod 554 is fixedly connected to an "L"-shaped extension plate 555. An arc rod 552 is fixedly installed on the side wall of the first side baffle 551, and the end of the arc rod 552 away from the first side baffle 551 is hinged to the second side baffle 553.

[0037] In this embodiment, the side wall of the pressure plate 538 away from the "L"-shaped rod 537 is made of flexible material, the purpose of which is to make the pressure plate 538 better fit the side wall of the monitoring point.

[0038] During specific operation, when the side wall of the monitoring point is displaced, the side wall of the monitoring point will continuously squeeze the pressure plate 538 and drive the pressure plate 538, the "L"-shaped rod 537, the pressure collecting plate 536 and the feedback rod 535 to continuously move toward the "Y"-shaped bracket 51, and at the same time, the pressure spring 533 is continuously compressed. When the pressure spring 533 is compressed to a certain extent, the feedback rod 535 will squeeze the electric control pressure rod 532 and make the alarm light 534 light up, and the monitoring probe 411 can capture the signal of the alarm light 534 lighting up and transmit it to the terminal display screen. At this time, the human can remotely know the displacement of the side wall of the monitoring point, so as to take further measures; As the feedback rod 535 continuously moves toward the "Y"-shaped bracket 51, the feedback rod 535 drives the cross plate 5351 and the tooth plate 5352 to move synchronously, and the tooth plate 5352 meshes with the driving gear 543 and drives the rotating shaft 542 and the wire wheel 544 to rotate, and the wire wheel 544 drives the traction rope 545 to reel up, thereby driving the first side baffle plate 551 to rotate around its hinge point, and at the same time drives the arc rod 552 and the second side baffle plate 553 to move toward the side wall of the monitoring point. When the alarm light 534 is on, the second side baffle plate 553 will abut against the side wall of the pressure plate 538. The blocking effect of the second side baffle plate 553 can prevent the side wall of the monitored point from further displacement, and the second side baffle plate 553 can also support and block the side wall below the displacement point. In addition, the No. 2 electric push rod 554 can drive the "L"-shaped extension plate 555 to move to the outside of the first side baffle plate 551, thereby supporting and blocking the side wall above the displacement point, thereby preventing further collapse of the side wall of the tunnel.

[0039] The working principle of the present invention when in use:

[0040] 1: During the coal mining process, the coal mine deep displacement monitoring device is driven to move to the monitored position in the tunnel by manually pushing the handrail 31. At this time, the monitoring component 5 is not in contact with the side wall of the monitoring point. Then the adjusting motor 42 is started, and the screw 43 is driven to rotate by the adjusting motor 42. Under the action of the limit rod 45, the lifting block 44 will drive the monitoring component 5 to move upward or downward, so as to adjust the monitoring height. When the monitoring height is determined, the remote-controlled electric control wheel 11 then drives the bottom plate 1 to make fine adjustments so that the end of the monitoring component 5 is in contact with the side wall of the monitored point. During the monitoring process, the lighting assembly 32 can provide lighting, so that the monitoring probe 411 can more clearly capture the feedback of the monitoring component 5.

[0041] Second: Start the No. 1 electric push rod 22, and drive the circular plate 23 to move downward through the No. 1 electric push rod 22. Under the action of the support rod 24, the "T"-shaped push rod 25 will drive the support spring 26 to be compressed, so that the support plate 27 and the insert gear 28 move downward, and finally the insert gear 28 is inserted into the ground at the monitoring point, thereby playing a certain supporting role for the coal mine deep displacement monitoring device and ensuring the stability of the coal mine deep displacement monitoring device during the monitoring process.

[0042] 3: When the side wall of the monitoring point is displaced, the side wall of the monitoring point will continuously squeeze the pressure plate 538 and drive the pressure plate 538, the "L"-shaped rod 537, the pressure collecting plate 536 and the feedback rod 535 to continuously move toward the "Y"-shaped bracket 51. At the same time, the pressure spring 533 is continuously compressed. When the pressure spring 533 is compressed to a certain extent, the feedback rod 535 will squeeze the electric control pressure rod 532 and make the alarm light 534 light up. The monitoring probe 411 can capture the signal of the alarm light 534 lighting up and transmit it to the terminal display screen. At this time, the human can remotely know the displacement of the side wall of the monitoring point and take further measures.

[0043] Fourth: When the feedback rod 535 continuously moves toward the "Y"-shaped bracket 51, the feedback rod 535 drives the horizontal plate 5351 and the tooth plate 5352 to move synchronously, and the tooth plate 5352 meshes with the driving gear 543 and drives the rotating shaft 542 and the wire wheel 544 to rotate, and the wire wheel 544 drives the traction rope 545 to reel up, thereby driving the first side baffle 551 to rotate around its hinge point, and at the same time drives the arc rod 552 and the second side baffle 553 to move toward the side wall direction of the monitoring point. When the alarm light 534 is on, the second side baffle plate 553 will abut against the side wall of the pressure plate 538. The blocking effect of the second side baffle plate 553 can prevent the side wall of the monitored point from further displacement, and the second side baffle plate 553 can also support and block the side wall below the displacement point. In addition, the No. 2 electric push rod 554 can drive the "L"-shaped extension plate 555 to move to the outside of the first side baffle plate 551, thereby supporting and blocking the side wall above the displacement point, thereby preventing further collapse of the side wall of the tunnel.
