Description

Technical Field

[0001] The utility model belongs to the technical field of mountain protection early warning, and particularly relates to a landslide protection monitoring device. Background Technique

[0002] Landslides, as a serious geological disaster, pose a huge threat to the safety of human life and property. With the acceleration of the urbanization process, the importance of landslide monitoring and early warning technology has become increasingly prominent. The existing landslide monitoring technologies mainly include geometric monitoring, physical monitoring, and external disturbance factor monitoring, such as deformation displacement monitoring, groundwater monitoring, and rainfall monitoring. However, these traditional monitoring methods have certain limitations, such as being easily interfered by environmental factors, inaccurate monitoring, and inability to accurately give early warnings in advance.

[0003] The prior art with the publication number of CN117848559A discloses a landslide thrust monitoring device, which uses a force-sensing diaphragm to convert the landslide force into a deformation amount, and calculates the magnitude of the landslide force through the wavelength change of the fiber Bragg grating. This device can accurately monitor the sliding and deformation of the landslide, but this deformation monitoring only stays on the surface of the landslide, and the sliding of many landslides is from deep to shallow, and this equipment cannot monitor the deformation and sliding of deep landslides.

[0004] The prior art with the publication number of CN206563552U proposes a distributed landslide deep displacement real-time monitoring device, which uses the distributed optical fiber sensing technology to realize the real-time monitoring of the deep deformation of the landslide through an optical time domain reflectometer and a sensing optical fiber. This device can accurately monitor the deep deformation of the landslide, but this device fails to give a landslide early warning in combination with external factors, such as rainfall, falling rocks, and earthquakes. And in plateau areas or areas with more slag stones, the landslide monitoring device cannot be protected, and it is easily damaged by the rolling stones, ultimately causing damage to the device, increasing the cost of equipment maintenance.

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Embodiment 1

[0036] The landslide protection and monitoring device of the utility model, as Figure 1 shown, includes a support column 16 and a protection housing 13. The protection housing 13 is made of a material with relatively high strength such as aluminum-magnesium alloy. The support column 16 is located inside the protection housing 13, and the bottom end of the support column 16 penetrates through the bottom of the protection housing 13. A cover plate is movably connected to the top of the protection housing 13. When the wind monitoring device 11 monitors that the wind speed is relatively high or the acoustic wave sensor 23 monitors that a falling rock is falling, by covering the cover plate, it can avoid damage to the monitoring device caused by the falling rock. A servo motor 15 is installed at the position where the protection housing 13 is connected to the cover plate relatively. The servo motor 15 drives the cover plate to rotate.

[0037] Specifically, the protection housing 13 and the cover plate can be movably connected through a hinge, so that the cover plate can rotate around the axis of the hinge. At this time, the output end of the servo motor 15 is fixedly connected to the part of the hinge connected to the cover plate. By starting the servo motor 15, the cover plate can be driven to rotate. The servo motor 15 is also connected to the data processing center 18 inside the protection housing 13 through a circuit.

[0038] The data processing center 18 includes a ZigBee coordinator, an embedded ARM processor, and an FPGA chip. The model of the embedded ARM processor is AT91SAM7S64C, and the model of the FPGA chip is EP2C20.

[0039] Further, a support lifting column 4 is connected above the support column 16 through a lifting mechanism. The lifting mechanism is used to drive the support lifting column 4 to move up and down relative to the support column 16; when the cover plate needs to be closed, first lower the support lifting column 4 into the protection housing 13 through the lifting mechanism.

[0040] A photovoltaic power generation mechanism is arranged at the top of the support lifting column 4. A wind monitoring device 11, a warning mechanism, and a signal enhancement and transmission device 8 are also arranged on the support lifting column 4. The wind monitoring device 11, the warning mechanism, and the signal enhancement and transmission device 8 are signal-connected to the data processing center 18.

[0041] Specifically, the warning mechanism includes a warning light 5 and an alarm 7. The warning light 5 and the alarm 7 are both signal-connected to the data processing center 18. The warning light 5 and the alarm 7 are fixedly connected to the support lifting column 4 through a connecting rod 6.

[0042] When the monitoring device monitors a landslide risk, a warning is given simultaneously through the warning light 5 and the alarm 7, which is convenient for the operators to know the landslide risk in the first time.

[0043] The wind power monitoring device 11 and the signal enhancement and transmission device 8 are respectively fixed to the support lifting column 4 through a pair of support rods 10. To further improve the stability of the wind power monitoring device 11 and the signal enhancement and transmission device 8, the wind power monitoring device 11 and the signal enhancement and transmission device 8 are also respectively fixed by passing a support cross bar through the support lifting column 4.

[0044] The wind blades of the wind power monitoring device 11 are also connected to a wind power generator through a circuit. The wind power generator is electrically connected to a controller, and the controller is electrically connected to the power supply 9 inside the protection housing 13, converting wind energy into electrical energy for storage. The power supply 9 is used to provide electrical energy to the devices that need to consume electrical energy in the monitoring device, and the power supply 9 can also be externally connected for electrical energy supplementation.

[0045] An acoustic wave sensor 23 and a water content monitor 24 are also provided at the bottom of the protection housing 13. Specifically, a plurality of support foot frames 22 are fixedly connected to the bottom of the protection housing 13. The support foot frames 22 are used to insert into the soil to fix the monitoring device, and an acoustic wave sensor 23 is fixedly connected to each support foot frame 22; the water content monitor 24 is fixedly connected to the side wall of the part of the support column 16 that passes through the bottom of the protection housing 13. The part of the support column 16 that passes through the bottom of the protection housing 13 is also inserted into the soil, and the water content monitor 24 enters the soil along with the support column 16 to monitor the water content in the soil. The acoustic wave sensor 23 and the water content monitor 24 are signal-connected to the data processing center 18.

[0046] As Figure 2 shown, the data processing center 18 is also connected to a displacement monitoring mechanism, including a conical housing 29. The top of the conical housing 29 is connected to a protection frame 25. A plurality of grooves 26 are formed in the conical housing 29 along the circumferential direction of the conical housing 29 from bottom to top. Displacement sensors 27 are fixedly connected to the conical housing 29 at positions corresponding to the grooves 26. The displacement sensors 27 are signal-connected to a demodulator 28, and the demodulator 28 is connected to the data processing center 18 through a circuit.

[0047] The conical housing 29 is buried under the soil. The deformation from the inside to the outside of the landslide can be monitored in real time through the displacement sensors 27. Once deformation is detected, a signal can be transmitted to the data processing center 18, and the data processing center 18 controls the warning light 5 and the alarm 7 to give a landslide warning.

[0048] Furthermore, the displacement sensor 27 is a fiber Bragg grating displacement sensor 27.

[0049] Embodiment 2

[0050] On the basis of Embodiment 1, as Figure 3As shown in the figure, in the landslide protection monitoring device of the present utility model, the lifting mechanism includes hydraulic cylinders 17 arranged on opposite sides of the support column 16. A hydraulic lifting rod 12 is movably connected inside the hydraulic cylinder 17. One end of the hydraulic lifting rod 12 away from the hydraulic cylinder 17 is fixedly connected with a fixing ring 14. The fixing ring 14 is fixedly connected to the bottom of the support lifting column 4. At the same time, the support rod 10 for fixing the wind monitoring device 11 and the signal enhancement transmission device 8 is fixedly connected to the fixing ring 14.

[0051] The lower liquid inlet of the hydraulic cylinders 17 on both sides is connected with an electro-hydraulic servo valve 19. The upper liquid outlet of the hydraulic cylinder 17 is communicated with a hydraulic return column 20. The hydraulic return column 20 is located on both sides of the support column 16 and the hydraulic return column 20 is parallel to the hydraulic cylinder 17. The bottom of the hydraulic return column 20 is connected to the liquid inlet of the electro-hydraulic servo valve 19. The electro-hydraulic servo valve 19 is connected to the data processing center 18.

[0052] Further, a pressure sensor 21 is fixedly connected inside the hydraulic cylinder 17 directly below the hydraulic lifting rod 12. The pressure sensor 21 is electrically connected to the electro-hydraulic servo valve 19.

[0053] That is, when ascending operation is required, the data processing center 18 controls the electro-hydraulic servo valve 19 to inject hydraulic pressure into the hydraulic cylinder 17. The hydraulic lifting rod 12 moves upward under the action of the increased pressure inside the hydraulic cylinder 17. Since the hydraulic lifting rod 12 is fixedly connected to the fixing ring 14, when the hydraulic lifting rod 12 ascends, it drives the support lifting column 4 to ascend. When the hydraulic lifting rod 12 ascends to the specified position, the data processing center controls the electro-hydraulic servo valve 19 to stop the operation. At this time, the hydraulic cylinder 17 maintains a high-pressure state, so that the hydraulic lifting rod 12 will not drop.

[0054] When descending operation is required, the data processing center 18 controls the electro-hydraulic servo valve 19 to reduce the pressure of the hydraulic cylinder 17. The hydraulic pressure inside the hydraulic cylinder 17 returns to the electro-hydraulic servo valve 19 through the hydraulic return column 20. The pressure inside the hydraulic cylinder 17 decreases. Under the action of gravity, the hydraulic lifting rod 12 drives the support lifting column 4 to descend. When the bottom of the hydraulic lifting rod 12 touches the pressure sensor 21, the electro-hydraulic servo valve 19 stops working.

[0055] Embodiment 3

[0056] On the basis of Embodiment 2, as Figure 4 shown in the figure, in the landslide protection monitoring device of the present utility model, the photovoltaic power generation mechanism includes an angle regulator 3. The angle regulator 3 is fixedly connected to the top of the support lifting column 4. The angle regulator 3 is movably connected with a photovoltaic panel 1 through an angle adjusting rod 2. The angle regulator 3 is used to adjust the tilt angle of the photovoltaic panel 1;

[0057] The photovoltaic panel 1 is electrically connected to a transformer. The transformer and the controller are electrically connected to store the electric energy converted by the photovoltaic panel 1.

[0058] Further, the angle adjuster 3 includes a housing 3-1. A support plate 3-4 is fixedly connected to the bottom of the housing 3-1 near one side of the photovoltaic panel 1, and the support plate 3-4 is movably connected to the photovoltaic panel 1 on the side away from the housing 3-1.

[0059] A driving motor 3-2 is fixedly installed at the bottom inside the housing 3-1. The output end of the driving motor 3-2 is connected to a threaded rod 3-3. One end of the threaded rod 3-3 away from the driving motor 3-2 is movably connected to the housing 3-1. At the same time, the extending direction of the threaded rod 3-3 passes through the photovoltaic panel 1. A sliding block 3-5 is movably connected to the threaded rod 3-3, and the sliding block 3-5 is movably connected to the angle adjusting rod 2. A limiting groove 3-6 for the movement of the angle adjusting rod 2 is formed on the housing 3-1. On the one hand, the limiting groove 3-6 provides a movement space for the angle adjusting rod 2, and on the other hand, it can limit and support the angle adjusting rod 2.

[0060] That is, when the angle of the photovoltaic panel 1 needs to be adjusted, the driving motor 3-2 is started. The driving motor 3-2 drives the threaded rod 3-3 to rotate. Under the rotational movement of the threaded rod 3-3, the sliding block 3-5 moves linearly relative to the threaded rod 3-3. Since the sliding block 3-5 is movably connected to the angle adjusting rod 2, it can drive the photovoltaic panel 1 to adjust the angle.

[0061] When in use, the landslide prevention and monitoring device of the present utility model can give a landslide warning according to different monitoring situations.

[0062] For the landslide deformation warning, the landslide is mainly monitored in real time through the displacement sensor 27. When the displacement sensor 27 detects deformation from the inside to the outside of the landslide, the displacement sensor 27 transmits the deformation data to the demodulator 28. The demodulator feeds back the data to the data processing center 18. The data processing center 18 transmits the data to the cloud for analysis through the signal enhancement transmission device 8. If the deformation data is greater than the set deformation threshold, a signal is sent to the data processing center 18 for landslide warning.

[0063] For the earthquake-triggered landslide warning, it is mainly monitored in real time through the acoustic wave sensor 23 fixedly connected to the support leg 22. When an earthquake or strong vibration occurs in the area around the landslide, the acoustic wave sensor 23 receives the vibration signal and transmits the vibration frequency data to the data processing center 18. The data processing center 18 transmits the vibration frequency data to the cloud for analysis through the signal enhancement transmission device 8. If the vibration frequency data is greater than the set vibration frequency threshold, a signal is sent to the data processing center 18 for landslide warning.

[0064] For rainfall-triggered landslide warning, the water content in the soil is mainly monitored in real time by the water content monitor 24 inserted into the soil. The water content monitor 24 transmits the water content data in the soil to the data processing center 18. The data processing center 18 transmits the soil water content data to the cloud for analysis through the signal enhancement transmission device 8. If the soil water content data is greater than the set threshold, a signal is sent to the data processing center 18 for landslide warning.

[0065] For landslide warning, the data processing center 18 controls the warning light 5 and the alarm 7 to flash the warning light and give an alarm sound reminder. After warning for a period of time, the data processing center 18 controls the lifting mechanism to lower the support lifting column 4 into the protection housing 13, and at the same time starts the servo motor 15 to rotate the cover plate of the protection housing 13 to the top of the protection housing 13 to protect the overall monitoring device.
