Description

Technical Field

[0001] This utility model belongs to the field of slope monitoring technology, and specifically relates to a slope monitoring device. Background Technology

[0002] Road slopes are sloping surfaces with a certain gradient formed on both sides of roads (highways, railways, etc.) to meet road alignment requirements, overcome terrain elevation differences, adapt to geological conditions, or for roadbed filling and excavation. They are a crucial component of road engineering, directly affecting the safety, stability, economy, and service life of roads. Because slopes have a certain inclination, they are susceptible to landslides; therefore, slope monitoring devices are needed to monitor slope displacement changes in real time.

[0003] For example, a flexible slope displacement device disclosed in application number CN201320362485.X involves drilling holes in the slope and burying a flexible displacement monitoring tube into the holes to a certain depth. The flexible displacement monitoring tube is then fixed with cement-mixed soil, with both ends sealed. A tubular spring is installed inside the tube, and a piezoresistive resistor is installed in the gap between the tubular spring and the inner wall of the flexible monitoring tube. The piezoresistive resistor is connected to a computer terminal via a sensor. When the slope collapses, the soil crushes the cement-mixed soil and further bends the flexible monitoring tube. At this time, the tubular spring is compressed and stretched, applying force to the piezoresistive resistor. The piezoresistive resistor transmits the data to the computer terminal via the sensor, allowing monitoring personnel to monitor the slope displacement changes in a timely manner through the computer terminal.

[0004] However, when the slope collapse is not severe, the displacement of the slope is not enough to crush the cement-mixed soil and bend the flexible displacement monitoring tube, making it difficult for the piezoresistor to work and resulting in poor monitoring effect. At the same time, the device can only monitor the displacement of a single area on the slope and cannot monitor multiple areas on the slope at the same time. Utility Model Content

[0005] Based on the problems mentioned in the background technology above, this utility model provides a slope monitoring device to solve the problem that when the slope collapse degree is not high, the slope displacement is difficult to crush the cement-mixed soil and bend the flexible displacement monitoring tube, making it difficult for the piezoresistor to work, resulting in poor monitoring effect; at the same time, the device can only monitor the displacement of a single area point on the slope and cannot monitor multiple areas points on the slope at the same time.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A slope monitoring device, comprising:

[0008] The box body has a fixed base at its bottom;

[0009] The insertion components are provided in multiple ways, and each insertion component is rectangular in shape when viewed from above. Each insertion component is provided with a tensioning member at its top.

[0010] Displacement measuring components, wherein multiple displacement measuring components are provided, and all of them are located inside the housing;

[0011] The scale lines are set on the inner wall of the box.

[0012] Based on the above technical solution, the present invention has made the following improvements:

[0013] Furthermore, the insertion component includes an arch frame, with a support at the top of the arch frame and fixing plates at the bottom of both sides of the arch frame. Each fixing plate is arrayed with multiple locking posts, and each locking post has an insertion plate at its bottom.

[0014] Furthermore, the tensioning component includes a second steel cable, one end of which is provided with a stud and the other end with a collar, which is fitted onto the top of the support.

[0015] Furthermore, the displacement measuring component includes pulleys, and multiple pulleys are provided and are obliquely offset and rotated on the inner wall of the housing. Multiple guide tubes are provided on one side wall of the housing, and each guide tube corresponds to the height position of a corresponding pulley. A steel cable is laid on each pulley, and a conical plumb bob is provided at one end of each steel cable. The tip of each conical plumb bob points to the zero point of the scale line. The other end of each steel cable passes through the guide tube at the corresponding height and extends to the outside of the tube, and is provided with a threaded sleeve. A corresponding stud is screwed into each threaded sleeve.

[0016] Furthermore, a buckle plate is detachably provided on one side of the box body by screws, and a viewing panel is provided on the buckle plate, the viewing panel facing the scale line.

[0017] Furthermore, a camera is installed on the inner wall of the buckle plate located below the visual panel, and the camera is positioned opposite the scale line.

[0018] The beneficial effects of this utility model are:

[0019] 1. By combining a box, various insertion components, various traction components, displacement measuring components, and scale lines, the box is placed at the top of the slope during use. The insertion components are arrayed and inserted at different heights on the slope. Then, the traction components are used to connect the insertion components to the displacement measuring components. When soil slippage occurs in a certain height area of ​​the slope, the insertion component at the corresponding height position can move accordingly. When the insertion component moves, the corresponding traction component can pull the corresponding part in the displacement measuring component. By observing the displacement distance of the corresponding part in the displacement measuring component on the scale line, it is possible to know whether a landslide has occurred in a certain height area of ​​the slope and the displacement of the landslide. Thus, it is possible to monitor multiple points on the slope.

[0020] 2. Furthermore, by inserting each component in an array at different heights on the slope, it can act as an anti-nailing device, thereby reducing the risk of slope slippage. Attached Figure Description

[0027] like Figures 1-3 As shown, a slope monitoring device includes:

[0028] Box 101, with a fixing seat 105 at the bottom of box 101. The fixing seat 105 is assembled on the concrete pouring base at the top of the slope by anchor bolts, thereby realizing the installation of box 101 at the top of the slope.

[0029] The insertion components are provided in multiple ways. The insertion components include an arch frame 201, a support 202 on the top of the arch frame 201, and fixing plates 203 on both sides of the bottom of the arch frame 201. Each fixing plate 203 has multiple locking posts 204 arranged in an array, and each locking post 204 has an insert plate 205 at its bottom, so that the overall outline of each insertion component is rectangular when viewed from above. In use, by inserting each insert plate 205 in each insertion component obliquely into the slope, each insertion component is arranged in an array and inserted into different height positions of the slope.

[0030] Each insertion component is equipped with a tensioning member at its top. The tensioning member includes a second steel cable 401. One end of the second steel cable 401 is equipped with a stud 402, and the other end is equipped with a collar 403. The collar 403 is fitted onto the top of the bracket 202. The bracket 202 in the insertion component is connected to the second steel cable 401 by the collar 403, so that the second steel cable 401 and the insertion component are assembled.

[0031] The displacement measuring components are provided in multiples and are all located inside the housing 101. Each displacement measuring component includes pulleys 301, which are arranged obliquely and rotatably on the inner wall of the housing 101. Multiple guide tubes 106 are provided on one side wall of the housing 101. Each guide tube 106 corresponds to the height position of the corresponding pulley 301. A steel cable 302 is laid on each pulley 301. One end of each steel cable 302 is provided with a conical head 303. The tip of each conical head 303 points to the zero point of the scale line 501. The other end of each steel cable 302 passes through the guide tube 106 at the corresponding height and is provided with a threaded sleeve 304. A corresponding stud 402 is screwed into each threaded sleeve 304. The steel cable 302 and the steel cable 401 are connected by the combination of the threaded sleeve 304 and the stud 402.

[0032] When soil slippage occurs at a certain height of the slope, the insertion component at the corresponding height of the slope can move accordingly. When the insertion component moves, the corresponding steel cable 302 in the displacement measuring component can be pulled by the corresponding steel cable 401, so that the corresponding cone head 303 moves upward.

[0033] The scale line 501 is set on the inner wall of the box 101. After the corresponding cone head 303 moves upward, by observing the position of the tip of the cone head 303 on the scale line 501, it is possible to know whether a landslide has occurred in the corresponding height area of ​​the slope and the amount of landslide displacement. Thus, it is possible to monitor multiple points on the slope. Furthermore, by inserting each insertion component in an array on different height areas of the slope, it can drive anti-nailing nails into the slope, which can further reduce the risk of slope slippage.

[0034] A buckle plate 103 is detachably provided on one side of the box 101 by means of screws 102. The buckle plate 103 can close the side opening of the box 101. A viewing plate 104 is provided on the buckle plate 103. The viewing plate 104 faces the scale line 501. The area of ​​the scale line 501 inside the box 101 can be seen from the outside of the box 101 through the viewing plate 104.

[0035] A camera is installed on the inner wall of the mounting plate 103 located below the visual panel 104. The camera is positioned opposite the scale line 501 and can continuously capture images of the scale line 501 inside the cabinet 101. Infrared supplementary lighting ensures clarity at night. The images captured by the camera are uploaded to the cloud / public IP via a 4G router inserted with an IoT SIM card. The NVR / computer in the monitoring center then receives the video stream through port mapping or VPN tunnel, displays it in real time, and automatically stores it, allowing staff in the monitoring center to remotely view the image of the scale line 501 inside the cabinet 101. The camera and router are powered by a 100W solar panel that generates approximately 400Wh of electricity per day (with 4 hours of sunshine), which is charged into the battery through an MPPT controller at an efficiency of >95%.
