Description

Technical Field

[0001] The utility model relates to the technical field of deformation monitoring, in particular to a high slope deformation monitoring device. Background Art

[0002] The stability of high and steep slopes has always been a focus of geotechnical engineering circles due to its complex geological conditions. Figure 1 As shown, in areas with soft geology, a concrete support 2 is usually poured on top of the slope 1, so the plane of the concrete support 2 is monitored for deformation at regular intervals.

[0003] However, some staff members are unable to check the deformation of the slope in real time. If the deformation of the slope cannot be monitored in time, it is easy to have a greater impact. Therefore, we propose a high slope deformation monitoring device to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a high slope deformation monitoring device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high slope deformation monitoring device, including a concrete support, a fixed plate and a fixed rod, the fixed plate and the fixed rod are fixedly connected to the inclined surface of the concrete support and are perpendicular to the inclined surface, and a laser generator is provided on the upper left part of the concrete support.

[0006] Further preferably, a screw is fixedly connected between the two corresponding fixing plates, the outer side of the screw is threadedly connected to a rectangular plate, and the laser generator is fixedly connected to the rectangular plate.

[0007] Further preferably, the ends of the two screw rods close to each other extend outside the fixing plate and are respectively fixedly connected with a first bevel gear and a second bevel gear, and the first bevel gear is meshed with the second bevel gear.

[0008] Further preferably, a square rod is fixedly connected between the corresponding two fixed plates, the rectangular plate is slidably mounted on the outside of the square rod, and a first motor is fixedly connected to the bottom of the lower fixed plate, and the output shaft end of the first motor is fixedly connected to the bottom end of the screw rod on the left.

[0009] Further preferably, a transparent glass tube is fixedly connected between the fixing rod and the fixing plate, and the interior of the transparent glass tube is filled with a photochromic material.

[0010] Further preferably, the upper left portion of the concrete support is fixedly connected to a disc via a pointed rod, the top of the disc is fixedly connected to a second motor, and the output shaft end of the second motor is fixedly connected to the bottom of the rectangular plate.

[0011] Further preferably, an optical fiber line is fixedly connected between the two corresponding fixing rods, a photoelectric sensor is installed inside the fixing rod at the lower right, and the optical fiber line is fixedly connected to the input end of the photoelectric sensor.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the first motor of the utility model drives the left screw to rotate, and drives the upper screw to rotate through the first bevel gear and the second bevel gear, so that the left rectangular plate moves downward, and the upper rectangular plate moves rightward, thereby driving the laser generator to sweep the concrete support in the horizontal and vertical directions, and the laser generated by the laser generator irradiates the photochromic material in the transparent glass tube. When the concrete support is not deformed, the laser emitted by the laser generator is not blocked, but is completely absorbed by the photochromic material and then displays color. On the contrary, when the concrete support is deformed, the deformed area will block part of the laser, so that the photochromic material does not change color partially, so that it can be judged whether the concrete support is deformed, and the intersection area of ​​the extension lines of the non-color-changing areas of the two groups of photochromic materials is the deformation area;

[0013] The disc is fixed by a pointed rod, and the second motor drives the rectangular plate to rotate, and the rectangular plate drives the laser generator to rotate to sweep the concrete support area. The laser emitted by the laser generator irradiates the surface of the optical fiber line, and then the laser moves in the optical fiber line toward the input end of the photoelectric sensor. When the concrete support is not deformed, the emitted laser will be transmitted through the optical fiber line to the input end of the photoelectric sensor, and the photoelectric sensor will always be on. When the concrete support is deformed, the fan-shaped area formed by the emitted laser will be partially blocked by the deformed area. Similarly, the photoelectric sensor will not be lit when the laser sweeps over the deformed area, thereby determining whether the concrete support is deformed. BRIEF DESCRIPTION OF THE DRAWINGS

When the concrete support 2 is not deformed, the emitted laser will be transmitted through the optical fiber line 18 to the input end of the photoelectric sensor 14, and the photoelectric sensor 14 is always on. When the concrete support 2 is deformed, the fan-shaped area formed by the emitted laser will be partially blocked by the deformed area. Similarly, the photoelectric sensor 14 will not be lit when the laser sweeps over the deformed area, so that it can be judged whether the concrete support 2 is deformed;
