[0036] Embodiment 1:

[0037] Reference Figure 1-Figure 7 A slope displacement monitoring device includes a bearing plate 1 and a monitoring instrument 2. A protective cover 3 is fixedly connected to the top of the bearing plate 1. The monitoring instrument 2 is installed in the protective cover 3. A monitoring window 31 is opened on the side wall of the protective cover 3. The device also includes: a floor 4, a telescopic sleeve rod 41 is fixedly connected to the bottom of the floor 4, the bearing plate 1 is fixed to the top of the telescopic end of the telescopic sleeve rod 41, and a plurality of ground insertion rods 9 are fixed at equal intervals at the bottom of the floor 4. The bottom of the ground insertion rod 9 is conical and is used to effectively fix the floor 4 when it is inserted into the ground. The bottom sleeve of the floor 4 A protective cover 91 is connected, and the protective cover 91 can wrap the entire bottom of the floor 4 so as to protect the ground rod 9 during transportation to avoid damage to the ground rod 9 and accidental punctures, wherein a lifting part for pushing the supporting plate 1 to move is arranged on the top of the floor 4; a driving box 5, and the driving box 5 is fixed to the bottom of the supporting plate 1, wherein a sealing plate 51 is slidably connected inside the driving box 5, and the top of the sealing plate 51 passes through the protective cover 3, and a switching part for adjusting the closed and open states of the monitoring window 31 is arranged inside the driving box 5.

[0038] Reference Figure 1-Figure 4 , wherein the switching part includes a first screw rod 6, which is rotatably connected in the driving box 5, and a movable plate 61 is threadedly sleeved on the first screw rod 6, and the outer wall of the movable plate 61 fits with the inner wall of the driving box 5. A magnetic plate 62 is fixedly connected to the top of the movable plate 61, and the magnetic plate 62 and the bottom end of the blocking plate 51 repel each other magnetically. One end of the first screw rod 6 passes through the outside of the driving box 5, and a driving motor 63 is fixedly connected to the driving box 5. The output end of the driving motor 63 is connected to the outer end of the first screw rod 6 through a pulley group 64 for transmission; the second screw rod 42 is rotatably connected to the top of the floor panel 4, and a lifting ring 43 is threadedly sleeved on the second screw rod 42. A plurality of positioning rods 44 are fixedly connected to the side wall of the lifting ring 43, and the top of the positioning rod 44 is fixedly connected to the bottom of the bearing plate 1, and the top of the second screw rod 42 is connected to the outer end of the first screw rod 6 through a bevel gear group 45 for transmission.

[0039] By setting the above structure, the drive motor 63 is intermittently controlled to start. During the process of starting the drive motor 63, the transmission effect of the pulley group 64 is used to drive the first screw rod 6 to rotate, so that the movable plate 61 slides with the magnetic plate 62 to the side away from the bottom of the blocking plate 51. In this way, under the action of gravity, the blocking plate 51 will fall down by itself, thereby releasing the blockage of the protective cover 3. At the same time, the transmission effect of the bevel gear group 45 is used to drive the second screw rod 42 to rotate when the first screw rod 6 rotates, so that the lifting ring 43 slides along the second screw rod 42, so that the positioning rod 44 pushes the carrier plate 1 to move. When the movable plate 61 moves to the first When the screw rod 6 is away from one end of the blocking plate 51, the drive motor 63 is turned off, and the monitor 2 is started at this time to measure the slope data of the height, and then the drive motor 63 is turned on again to make the movable plate 61 move in the opposite direction along the first screw rod 6, and the blocking plate 51 is lifted upward by the repulsive effect between the magnetic plate 62 and the blocking plate 51, so as to achieve the blocking of the protective cover 3, so that the monitor 2 that stops monitoring work is sealed and wrapped in the protective cover 3, so as to prevent the monitor 2 from being eroded by environmental factors during long-term monitoring work, thereby improving the protection effect of the monitor 2, ensuring the measurement accuracy of the monitor 2, and effectively extending its service life;

[0040] The above steps are then repeated to measure the slope data at points at different heights, which improves the representativeness of the monitoring results. Then, after a period of time, the slope data at points at different heights are measured again. Finally, the two monitoring data before and after the same height point are compared to determine whether there is a risk of slope displacement so that timely management and control can be carried out. This achieves effective monitoring of slope points at different heights and effectively improves the accuracy of the monitoring results.

[0041] It should be noted that whenever the lifting ring 43 moves to the top of the second screw rod 42, the drive motor 63 will continue to rotate, driving the lifting ring 43 to reset and slide to the bottom of the second screw rod 42, thereby achieving zero height, so as to repeat the measurement of different height points; the opening and closing of the drive motor 63 can be achieved with the help of existing mature remote manual control or intelligent PLC control system.

[0042] Reference Figure 2-Figure 4 , wherein a rain collecting trough 7 is fixedly connected to the top of the protective cover 3, the bottom of the rain collecting trough 7 is inclined, a rain storage tank 71 is fixedly connected to the rain collecting trough 7, the rain collecting trough 7 and the rain storage tank 71 are connected, and a filter cotton 72 is fixedly connected to the inclined bottom of the rain collecting trough 7; an air blowing pipe 65 is fixed and connected to the side wall of the driving box 5, the other end of the air blowing pipe 65 passes through the supporting plate 1 and the rain storage tank 71 and extends into the protective cover 3, the output end of the air blowing pipe 65 faces the measuring end of the monitor 2 from top to bottom, and a one-way valve is arranged in the air blowing pipe 65.

[0043] It should be noted that the one-way valve in the air blowing pipe 65 can only allow the gas in the drive box 5 to enter the protective cover 3, and the gas pressure generated by the deadweight of the blocking plate 51 is greater than the thrust required to open the one-way valve in the air blowing pipe 65.

[0044] Through the arrangement of the above-mentioned structure, rainwater can be collected by the rain collecting trough 7, and the rainwater is filtered through the filter cotton 72 and then discharged into the rain storage tank 71. When the blocking plate 51 descends by its own weight, the gas in the slideway in the driving box 5 will be squeezed, and the one-way valve in the air blowing pipe 65 will be pushed open, so that this part of the gas will be blown along the air blowing pipe 65 to the measuring end of the monitor 2, thereby cleaning the measuring end of the monitor 2, improving the cleanliness of the measuring end of the monitor 2, and ensuring the measurement accuracy of the monitor 2. The air blowing pipe 65 passes through the rainwater stored in the rain storage tank 71, so that the rainwater can be used to cool the airflow, thereby reducing the temperature in the protective cover 3, realizing the heat dissipation of the monitor 2, and ensuring the service life of the monitor 2.

[0045] Reference Figure 3-Figure 7, wherein both sides of the outer wall of the driving box 5 are fixed and connected with an exhaust pipe 66, the other end of the exhaust pipe 66 passes through the bearing plate 1 and extends to the bottom of the protective cover 3, a one-way valve is arranged in the exhaust pipe 66, and a filter part is arranged on the lowest bending section of the exhaust pipe 66; the filter part includes two groups of filter boxes 8, the two groups of filter boxes 8 are respectively fixed on the exhaust pipes 66 on both sides, and the filter boxes 8 are connected with the exhaust pipe 66, a dust filter plate 81 is fixedly connected in the filter box 8, a cleaning pipe 82 is fixed and connected between the tops of the filter boxes 8 on both sides, and a rain storage tank 71 is fixed and connected A water guide pipe 83 is provided, the other end of which is connected to the cleaning pipe 82; a water guide plate 84 is fixedly connected to the top of the filter box 8, and the inclined lower end of the water guide plate 84 is close to the side wall of the dust filter plate 81; the bottom end of the filter box 8 is fixed and connected to a drain pipe 85, a sealing plate 86 is slidingly fitted on the bottom of the filter box 8, one end of the sealing plate 86 extends through the drive box 5, a guide groove 861 is provided on the sealing plate 86, a limiting plate 862 is fixedly connected to the sealing plate 86, and a return spring 863 is fixedly connected between the limiting plate 862 and the side wall of the filter box 8.

[0046] It should be noted that the one-way valve in the exhaust pipe 66 can only allow the gas in the protective cover 3 to enter the drive box 5, and the suction force generated by the repulsive force between the sealing plate 51 and the magnetic plate 62 in the drive box 5 is greater than the thrust required to open the one-way valve in the exhaust pipe 66.

[0047] By setting the above structure, when the blocking plate 51 is lifted up by the repulsive force of the magnetic plate 62, a suction effect is generated in the driving box 5, thereby opening the one-way valve in the exhaust pipe 66, so that the airflow in the protective cover 3 passes through the exhaust pipe 66 and enters the driving box 5, so as to firstly replenish the gas in the driving box 5 and ensure the continuation of the above-mentioned air blowing and cleaning effect, and secondly use the airflow to take away the dust in the protective cover 3, thereby improving the cleanliness of the protective cover 3 and ensuring the measurement accuracy of the monitor 2; and when the airflow flows through the exhaust pipe When the water level in the rain storage tank 71 exceeds the input end of the water guide pipe 83, it will enter the filter box 8 through the water guide pipe 83 and the cleaning pipe 82, and flow obliquely along the water guide plate 84 toward the upper part of the side wall of the dust filter plate 81, so as to clean the dust filter plate 81 with the collected rainwater, thereby improving the filtering effect of the dust filter plate 81 and realizing the effective use of rainwater, thereby improving the energy saving effect;

[0048] And when the movable plate 61 moves to the end of the first screw rod 6 away from the sealing plate 51 (that is, in the blowing stage, when the exhaust pipe 66 is in a blocked state), the sealing plate 86 will be squeezed to make the sealing plate 86 slide in the filter box 8 and stretch the reset spring 863 to make the guide groove 861 enter the filter box 8. At this time, the sewage in the filter box 8 will pass through the guide groove 861 and the drain pipe 85 and be discharged. When the movable plate 61 is reset, under the rebound action of the reset spring 863, the sealing plate 86 will be reset to the state of sealing the filter box 8 to ensure that there will be no leakage when the airflow in the protective cover 3 is subsequently extracted, thereby ensuring the reasonable operation of the device.

[0049] Embodiment 2:

[0050] Reference Figure 1-Figure 8 , which is basically the same as the first embodiment, and based on the first embodiment, a slope displacement monitoring method is proposed, comprising the following steps:

[0051] Step 1: First, insert the floor panel 4 into the soil for fixing;

[0052] Step 2: Use the monitoring device 2 to measure the road slopes at different heights on the same vertical line to obtain measurement data S1 at different heights;

[0053] Step 3: After a certain period of time, repeat step 2 to obtain measurement data S2 at different heights of the same vertical line;

[0054] Step 4: Compare S1 and S2 at different time periods at the same height to determine whether there is any displacement of the slope;

[0055] Step 5: When the result of step 4 is within the normal range, repeat steps 3 and 4 to achieve continuous monitoring.

[0056] Reference Figure 1-Figure 8In the present invention, when in use, first the ground in the installation area is leveled, and then the ground rod 9 is inserted into the ground soil to fix the floor 4, and then the drive motor 63 is intermittently controlled to start. During the process of starting the drive motor 63, the transmission effect of the pulley group 64 will drive the first screw rod 6 to rotate, so that the movable plate 61 and the magnetic plate 62 slide to the side away from the bottom of the blocking plate 51. In this way, under the action of gravity, the blocking plate 51 will fall down by itself, thereby releasing the blockage of the protective cover 3. At the same time, the transmission effect of the bevel gear group 45 will be used to drive the second screw rod 42 to rotate when the first screw rod 6 rotates, so that the lifting ring 43 slides along the second screw rod 42, so that the positioning rod 44 pushes the bearing plate 1 to move. When the movable plate 61 moves to the end of the first screw rod 6 away from the blocking plate 51, the drive motor 63 is turned off. At this time, the monitoring The measuring instrument 2 is started to measure the slope data at that height, and then the driving motor 63 is turned on again, so that the movable plate 61 moves in the opposite direction along the first screw rod 6, and the repulsive effect between the magnetic plate 62 and the sealing plate 51 is used to lift the sealing plate 51 upward, so as to achieve the blocking of the protective cover 3, so that the monitoring instrument 2 that stops monitoring work is sealed and wrapped in the protective cover 3, so as to prevent the monitoring instrument 2 from being eroded by environmental factors during long-term monitoring work, improve the protection effect of the monitoring instrument 2, ensure the measurement accuracy of the monitoring instrument 2, and effectively extend its service life; then repeat the above steps to measure the slope data at different height points, and then after a period of time, re-measure the slope data at different height points before and after, and finally compare the two monitoring data before and after the same height point, and then judge whether there is a displacement risk of the slope, so as to carry out timely management and control.

[0057] In addition, rainwater can be collected by the rain collecting trough 7, and the rainwater is filtered through the filter cotton 72 and discharged into the rain storage tank 71. When the blocking plate 51 descends by its own weight, the gas in the slideway in the driving box 5 is squeezed, and the one-way valve in the air blowing pipe 65 is pushed open, so that this part of the gas is blown along the air blowing pipe 65 to the measuring end of the monitor 2, thereby cleaning the measuring end of the monitor 2, improving the cleanliness of the measuring end of the monitor 2, and ensuring the measuring accuracy of the monitor 2. The air blowing pipe 65 passes through the rainwater stored in the rain storage tank 71, so that the rainwater can be used to cool the airflow, thereby reducing The temperature inside the low protection cover 3 is reduced, and the heat dissipation of the monitor 2 is realized, thereby ensuring the service life of the monitor 2; and when the blocking plate 51 is lifted up by the repulsive force of the magnetic plate 62, a suction effect is generated in the drive box 5, thereby opening the one-way valve in the exhaust pipe 66, so that the airflow in the protection cover 3 passes through the exhaust pipe 66 and enters the drive box 5, thereby firstly realizing the replenishment of the gas in the drive box 5, ensuring the continuation of the above-mentioned blowing and cleaning effect, and secondly using the airflow to take away the dust in the protection cover 3, thereby improving the cleanliness of the protection cover 3 and ensuring the measurement accuracy of the monitor 2; and when the airflow flows through the exhaust pipe When the rainwater in the rain storage tank 71 exceeds the input end of the water guide pipe 83, it will enter the filter box 8 through the water guide pipe 83 and the cleaning pipe 82, and flow obliquely along the water guide plate 84 to the upper part of the side wall of the dust filter plate 81, so as to use the collected rainwater to clean the dust filter plate 81, thereby improving the filtering effect of the dust filter plate 81 and realizing the effective use of rainwater, thereby improving the energy saving effect; and when the movable plate 61 moves to a position where the first screw rod 6 is away from the blocking plate 51 At the end (that is, in the blowing stage, when the exhaust pipe 66 is in a blocked state), the sealing plate 86 will be squeezed to make the sealing plate 86 slide in the filter box 8 and stretch the reset spring 863 to make the guide groove 861 enter the filter box 8. At this time, the sewage in the filter box 8 will pass through the guide groove 861 and the drain pipe 85 and be discharged. When the movable plate 61 is reset, under the rebound action of the reset spring 863, the sealing plate 86 will be reset to the state of blocking the filter box 8 to ensure that there will be no leakage when the airflow in the protective cover 3 is subsequently extracted, thereby ensuring the reasonable operation of the device.
