Description

Technical Field

[0001] This utility model relates to the field of slope soil displacement monitoring technology, and in particular to a slope soil displacement monitoring device. Background Technology

[0002] Slope stability is directly related to engineering safety. Traditional displacement monitoring relies heavily on manual measurements such as total stations, which has limitations such as low efficiency, discrete data, and difficulty in real-time early warning. With the development of automated sensing technologies such as GNSS and surveying robots, modern monitoring systems can collect three-dimensional displacement data of the ground surface with high precision and continuous operation. Through remote transmission and real-time analysis, these systems provide key data support for accurate early warning and stability assessment of landslide disasters.

[0003] While existing technologies can collect surface displacement data, they are limited to collecting surface data and cannot capture internal slope sliding. When the pressure inside the slope soil changes, it is impossible to deal with the slope that may collapse in advance.

[0004] Therefore, in order to solve the above problems, this utility model proposes a slope soil displacement monitoring device that can monitor changes in the internal pressure of slope soil and facilitate early treatment of slopes that may collapse. Utility Model Content

[0006] According to one objective of this utility model, this utility model provides a slope soil displacement monitoring device, wherein the displacement monitoring device is provided with a slope length monitoring direction and a displacement direction perpendicular to the slope length monitoring direction, and the slope soil displacement monitoring device includes:

[0007] A fixing plate, wherein the two opposite sides of the fixing plate are the slope soil side and the exposed side, respectively;

[0008] A number of corresponding earth pressure sensors and support members are provided. The earth pressure sensors are set on the slope soil side of the fixed plate. The two ends of the support members are a movable end and a fixed end, respectively. The movable end is connected to the earth pressure sensor. The fixed end is movably inserted through the fixed plate along the displacement direction and is located on the exposed side of the fixed plate. The earth pressure sensors and the support members are arranged sequentially at intervals along the slope length monitoring direction.

[0009] Two adjacent support members in the slope length monitoring direction have matching laser receivers and laser emitters respectively installed on opposite sides of their fixed ends in the slope length monitoring direction. A flexible laser circuit tube arranged along the slope length monitoring direction is provided between the laser receiver and the laser emitter.

[0010] Preferably, one end of the laser circuit tube is fixedly connected to the laser receiver, and the other end of the laser circuit tube is fixedly connected to the laser emitter.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This slope soil displacement monitoring device works by first displacing the earth pressure sensor when the soil at the slope edge begins to move. The earth pressure sensor detects the pressure at the slope edge in real time, and then, through the support structure, it further drives the displacement of the laser receiver and laser transmitter.

This allows staff to inspect the section in advance and take preventative measures against potential slope collapses.

[0024] The following description is intended to provide a detailed account of the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0025] See Figure 1-5 This utility model provides a technical solution: a slope soil displacement monitoring device, wherein the displacement monitoring device is provided with a slope length monitoring direction A and a displacement direction B perpendicular to the slope length monitoring direction A;

[0026] The slope soil displacement monitoring device includes:

[0027] A fixing plate 100, wherein the two opposite sides of the fixing plate 100 are the slope soil side and the exposed side, respectively;

[0028] A number of corresponding earth pressure sensors 200 and support members 300 are provided. The earth pressure sensors 200 are disposed on the slope soil side of the fixed plate 100. The two ends of the support member 300 are a movable end 300a and a fixed end 300b, respectively. The movable end 300a is connected to the earth pressure sensor 200. The fixed end 300b is movably inserted through the fixed plate 100 along the displacement direction B and is located on the exposed side of the fixed plate 100. The earth pressure sensors 200 and the support members 300 are arranged sequentially at intervals along the slope length monitoring direction A.

[0029] On the slope length monitoring direction A, two adjacent support members 300 have a matching laser receiver 400 and a laser emitter 500 respectively provided on opposite sides of their fixed ends 300b. A flexible laser circuit tube 600 arranged along the slope length monitoring direction A is provided between the laser receiver 400 and the laser emitter 500.

[0030] When the soil at the edge of the slope begins to move towards the slope, the earth pressure sensor 200 is displaced first. The earth pressure sensor 200 detects the pressure at the edge of the slope in real time. The earth pressure sensor 200 further drives the laser receiver 400 and the laser transmitter 500 to move through the support 300. When the signal between the laser receiver 400 and the laser transmitter 500 is interrupted, the laser receiver and the laser transmitter 500 send an alarm signal to the external monitoring module to remind that the pressure of the soil in that section has increased, so that the staff can check the section in advance and deal with the slope that may collapse in advance.

[0031] Furthermore, one end of the laser circuit tube 600 is fixedly connected to the laser receiver 400, and the other end of the laser circuit tube 600 is fixedly connected to the laser emitter 500;

[0032] The laser circuit tube 600 and the fixing plate 100 are fixedly connected on their exposed sides. By defining the connection relationship between the laser circuit tube 600, the laser receiver 400, the laser transmitter 500, and the fixing plate 100, the stable installation of the laser circuit tube 600 is ensured. When the slope deforms, the soil sensor can better drive the laser circuit tube 600 to deform, thereby sending out an alarm signal. Preferably, the fixing method can be adhesive bonding.

[0033] Furthermore, see Figure 5 The exposed side of the fixing plate 100 is provided with a receiving groove 101. The laser receiver 400, the laser emitter 500 and the laser circuit tube 600 are all embedded in the receiving groove 101. The receiving groove 101 not only fixes the laser receiver 400, the laser emitter 500 and the laser circuit tube 600, but also prevents them from extending outside the exposed side of the fixing plate 100, ensuring that the exposed side of the fixing plate 100 is flat, which can improve the service life of the device to a certain extent.

[0034] Further, see Figure 4 The laser circuit tube 600 is a hollow tube. A fixing rod 601 is detachably connected inside the laser circuit tube 600. The radially outer side of the fixing rod 601 is supported and connected to the radially inner side of the laser circuit tube 600. Before installation, the fixing rod 601 is inserted inside the laser circuit tube 600 to protect the integrity of the laser circuit tube 600 and prevent the transmission of laser light from being affected.

[0035] For the specific connection structure between the support member 300 and the fixing plate 100, please refer to [link / reference]. Figure 2The fixing plate 100 has an opening 102 that connects the slope soil side and the exposed side. The opening 102 is set along the displacement direction B. The support member 300 is movably set inside the opening 102. When the earth pressure sensor 200 drives the support member 300 to move, the movable member can move under the guidance of the opening 102 to stably drive the laser circuit tube 600 to move.

[0036] To enable the fixing plate 100 and the support member 300 to be adapted to slopes with different inclination angles, further see... Figure 3 The support member 300 includes a movable part 301 and a fixed part 302 connected sequentially between a movable end 300a and a fixed end 300b. A lockable hinge 303 is provided between the movable part 301 and the fixed part 302. In use, the movable part 301 can be rotated to a suitable angle and locked through the hinge 303 as needed to ensure that the earth pressure sensor 200 can cooperate with the movable part 301 to receive the compression of the slope soil. Preferably, both the movable part 301 and the earth pressure sensor 200 are horizontally arranged.

[0037] How to use:

[0038] The user first compacts the edges of the slope;

[0039] Install the fixing plate 100 onto the slope and secure it. Then connect the soil pressure sensor. Next, pull out the fixing rod 601 in the laser line tube 600 and activate the laser receiver 400 and laser transmitter 500. The light emitted by the laser transmitter 500 is transmitted along the laser line tube 600 to the laser receiver 400. When the soil on the slope begins to move towards the slope, the soil pressure device will shift, causing the laser receiver 400 to also shift when receiving the light emitted by the laser transmitter 500. When no signal is received, the laser receiver 400 will send an alarm to remind the staff that the soil pressure in that section has suddenly increased, allowing the staff to check that section in advance.

[0040] In summary, this slope soil displacement monitoring device, when soil displacement occurs, incorporates a design for precise early warning of landslides. It works in conjunction with a laser transmitter 500 and a laser receiver 400, and further in conjunction with a laser circuit tube 600, to achieve real-time detection of pressure at the slope edge. This allows the device to alert staff to inspect the soil in that section when soil pressure suddenly increases, enabling early intervention to address potential slope collapses.

[0041] This slope soil displacement monitoring device has low installation cost, wide applicability, and high working efficiency.

[0042] The embodiments described above are only used to illustrate the technical ideas and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. The scope of patent application of this utility model should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in this utility model still fall within the patent scope of this utility model.
