[0049] In summary, during use, the positioning mechanism 1 is first fixed in a suitable position, and then the connecting rod mechanism 2 is rotated to make the bottom monitoring mechanism 4 and the top monitoring mechanism 3 both contact the slope, and then the stabilizing mechanism 5 is used to support the connecting rod mechanism 2, so that the top monitoring and bottom monitoring mechanisms 4 are more convenient to operate and use. The top monitoring mechanism 3 is connected to the connecting rod mechanism 2 to detect the displacement distance of the surface of the slope, and the bottom monitoring mechanism 4 is also connected to the connecting rod mechanism 2 to monitor the displacement distance inside the slope. During use, the bottom monitoring mechanism 4 needs to insert the insertion plate 42 into the ground, and then open the through hole. At this time, if the bottom soil is displaced, it will directly squeeze the rotating plate 44 through the through hole, causing the rotating plate 44 to rotate, which can be directly seen from the surface The displacement change of the underlying soil makes it easy to operate and use, and does not need to rely on signal connection. It has a wide range of applications. When installing the underlying monitoring mechanism 4, the insertion plate 42 needs to be inserted into the ground to a suitable distance. Before insertion, the through hole needs to be blocked with the baffle 43 to prevent soil from directly passing through the through hole into the insertion plate 42 during the insertion process and affecting the use of the rotating plate 44. When the insertion plate 42 is fully inserted into the ground, the baffle 43 can be moved upward by rotating the third screw 412 to open the through hole. When the underlying soil moves to squeeze the rotating plate 44, the rotating plate 44 will rotate, and the rotating plate 44 and the fixed shaft 45 are fixedly connected, and the fixed shaft 45 and the insertion plate 42 are rotatably connected, so the fixed shaft can be directly moved. 45 rotates synchronously, thereby causing the second indicator rod 47 on the fixed shaft 45 to rotate synchronously, and the second indicator rod 47 points to the scale line of the second scale plate 46, so that the displacement change of the underlying soil can be directly judged. The inserted plate 42 can be set inside the rotating plate 44, so as to avoid the displacement of the surface soil and directly affect the use of the rotating plate 44. Since the rotation of the rotating plate 44 must pass through the through hole, and the through hole is located in the underlying soil, the influence of the movement of the surface soil on the rotating plate 44 can be eliminated. The inserted plate 42 needs to be kept vertical during use, so the fixed sleeve 41 can be adjusted by the rotation between the connecting shaft 411 and the round block 22. In the process of inserting the inserted plate 42 into the ground, in order to maintain stability, the second screw 410 can be rotated to make the second screw 410 The second screw rod 410 moves and is inserted into the limiting hole of the connecting shaft 411, so that the connecting shaft 411 cannot rotate, and the connecting shaft 411, the rotating block 49 and the fixing sleeve 41 are all fixed. At this time, the insertion plate 42 can be directly inserted into the ground. During the insertion of the insertion plate 42 into the ground, the insertion plate 42 can be directly hammered from above with a hammer so that it is forced into the ground. When the stabilizing mechanism 5 is in use, after determining the connecting rod angle and the positions of the bottom monitoring mechanism 4 and the top monitoring mechanism 3, the fourth screw rod 53 is directly manually rotated, and the fourth screw rod 53 can move downward, thereby driving the connecting seat 51 to move downward synchronously, so that the connecting seat 51 contacts the slope and forms a support, and the fourth screw rod 53 is connected to the connecting seat 51 through the ball 52.Therefore, the connecting seat 51 can move at the bottom end of the fourth screw rod 53 to adapt to the inclination of the slope. When the top monitoring mechanism 3 is in use, the plug plate 31 is directly inserted into the ground, and the rotating rod 36 is kept parallel to the slope. The way of keeping parallelism is related to the angle of the connecting rod. After adjusting the angle of the connecting rod, the plug plate 31 is inserted into the ground to make the rotating rod 36 and the slope as parallel as possible. The purpose of keeping parallelism is that when the surface layer of the slope is displaced, the soil will directly move toward the bottom of the slope to drive the plug plate 31 to move. At this time, the bottom end of the connecting rod mechanism 2 is stabilized by the supporting mechanism and the bottom monitoring mechanism 4. Therefore, only the plug plate 31 moves, and the movement of the plug plate 31 will drive the sliding rod 33 to move. The sliding rod 33 slides on the rotating rod 36. If the rotating rod 36 and the slope There is a certain angle between the slopes, which will cause the slide bar 33 to disperse the force driven by the plug plate 31 into a force parallel to the rotating rod 36 and a force at a certain angle to the rotating rod 36. This will make the movement data of the slide bar 33 inconsistent with the movement data of the surface of the slope, affecting the monitoring result. The scale set on the rotating rod 36 can be used to judge the movement distance of the slide bar 33, and the displacement distance of the surface of the slope can be judged by the distance. By setting a connecting plate 37 on the plug plate 31, when there are more gravel and soil blocks rolling down the slope, it can be directly acted on the bottom end of the inclined part of the connecting plate 37, so that the entire connecting plate 37, the plug plate 31 and the slide bar 33 are rotated upward, and then the rotating rod 36 is rotated. The angle of rotation can be measured by the first indicator rod 362 and the round block 22 The circumferential scale lines on the side wall are displayed to facilitate the judgment of the rolling degree of the gravel on the slope. The positioning mechanism 1 mainly provides overall stability during use. During operation, the entire device is placed at the position where the slope needs to be monitored, and then the pile foundation 1002 is inserted into the ground until the entire base 1001 becomes firm and will not easily change with the displacement of the slope. Then the rotating shaft 1010 is rotated to make the worm 1009 on the rotating shaft 1010 drive the worm wheel 1007 to rotate, and the worm wheel 1007 drives the entire connecting block 1008 to rotate, and the connecting block 1008 drives the vertical rod 1006 to rotate, so that the vertical rod 1006 remains vertical, which is helpful to observe whether the entire positioning mechanism 1 is affected by the top monitoring mechanism 3 and the bottom monitoring mechanism 4 when using the device. The steel wire rope cooperates with the plumb bob 1005 and the first scale plate 1003 to better observe. For the convenience of use, when the surface slope is displaced and the plug plate 31 moves, the plug plate 31 will drive the slide bar 33 to move, and a first pressure sensor 35 is arranged in the long groove 331 opened on the slide bar 33. A movable slider 34 is also arranged on the rotating rod 36, and the slider 34 is located in the long groove 331. Therefore, when the slide bar 33 moves, it can contact the slider 34 and squeeze the first pressure sensor 35 to convert the pressure into an electrical signal output. When the pressure signal detected by the first pressure sensor 35 exceeds the preset alarm threshold, a signal will be sent to the buzzer 8.The buzzer 8 will emit an alarm sound after receiving the signal. The position of the slider 34 can be moved by rotating the first screw 39, thereby changing the distance between the first pressure sensor 35 and the slider 34, and then the surface slope displacement can be controlled to be within a predetermined range without alarming, and to contact and squeeze and alarm when it exceeds the predetermined range. By setting the first rotating ring 38, the first rotating ring 38 and the first annular groove can rotate, and there is a large resistance to rotation between the two. Therefore, the first rotating ring 38 can be rotated to make the second pressure sensor 381 on the first rotating ring 38 located at a suitable position. When the first indicator rod 362 is rotated to contact with the second pressure sensor 381 and squeeze is formed, the pressure can be converted into an electrical signal output. When the pressure signal detected by the second pressure sensor 381 exceeds the preset alarm threshold, , will send a signal to the buzzer 8, and the buzzer 8 will sound an alarm after receiving the signal. Similarly, the second rotating ring 48 and the second annular groove can rotate, and there is a large resistance to the rotation between the two. Therefore, the second rotating ring 48 can be rotated to make the third pressure sensor 481 on the second rotating ring 48 located at a suitable position. When the second indicator rod 47 on the fixed shaft 45 contacts and squeezes the third pressure sensor 481, the pressure can be converted into an electrical signal output. When the pressure signal detected by the second pressure sensor 381 exceeds the preset alarm threshold, a signal will be sent to the buzzer 8, and the buzzer 8 will sound an alarm after receiving the signal. Therefore, the top monitoring mechanism 3, the bottom monitoring mechanism 4 and the degree of surface gravel rolling can be judged by whether the buzzer 8 alarms, and the monitoring personnel do not need to observe the status of the device all the time. ,
