Description

Technical Field

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

[0002] To prevent landslides, rockfalls, and debris flows caused by heavy rainfall in a short period of time, it is necessary to monitor ground displacement in real time. Radar can be used to accurately measure surface displacement.

[0003] A slope displacement monitoring device disclosed in the Chinese invention patent application publication CN 215572764 U includes multiple radar reflectors arranged at different positions on the slope surface; and at least one radar transmitting / receiving unit for emitting electromagnetic waves to the multiple radar reflectors and receiving electromagnetic waves reflected by the multiple radar reflectors.

[0004] This technical solution uses a monitoring device with a radar reflection unit and a radar transmission / reception unit to achieve wireless monitoring and ensure the reliability of monitoring. Through the radar, the absolute position of any target on the slope can be determined, and the displacement of the slope can be effectively detected in advance. However, the radar in this technical solution is also fixed on the ground. When the part where the radar is installed is deformed and displaced, the detection is prone to false alarms of landslides, and there is a lack of ability to monitor the radar's own position. Utility Model Content

A bracket is fixedly installed at the bottom end of the radar, and the bracket is located within the detection range of the other two radars. The reflective substrate is also installed on the surface of the bracket.

[0008] Furthermore, the reflective base includes a fixed end at the bottom and a reflective end above the fixed end. The cross-section of the reflective end is an isosceles trapezoid, and the isosceles trapezoidal reflective end and the radar corresponding surface are provided with an acute-angled protrusion.

[0009] Furthermore, the fixed end includes plug-in strips evenly distributed below the reflective end, wherein the plug-in strip below the side where no protrusion is provided is provided with a threaded connection hole.

[0010] Furthermore, the bracket is divided into a fixed part and a rotating part, the rotating part is fixedly installed above the fixed part, and the radar is fixedly installed above the rotating part.

[0011] Furthermore, the radar includes a signal generating unit for sending signals, a signal receiving unit for receiving reflected signals, a storage unit for storing initial data, a temporary storage unit for temporarily storing collected data, an information comparison unit for comparing the temporarily stored data and the collected data, and an information transmission unit for sending the comparison information.

[0012] Furthermore, the bottom end of the reflective end is provided with an edge, the surface of the edge and the surface of the fixed end are provided with through holes, and the edge and the fixed end are connected by bolts.

[0013] The beneficial effects of the present invention are:

[0014] 1.

The detection information is continuously collected for comparison, which can detect slope movement in time. At the same time, after the radar is displaced, it can be detected by adjacent radars to avoid false alarms due to radar displacement.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See Figures 1-4 A high-precision slope displacement monitoring device includes a reflective matrix 1 randomly distributed on the slope, and radars 2 that emit different frequencies and are respectively set on the front, left and right sides of the slope. A bracket 3 is fixedly installed at the bottom end of the radar 2. The bracket 3 is located within the detection range of the other two radars 2. The reflective matrix 1 is also installed on the surface of the bracket 3. Through such a setting, the radar 2 is used to detect the distance of the reflective matrix 1 set at the corresponding bracket 3, so as to determine whether the part where the radar 2 is installed has moved.

[0023] The reflective substrate 1 includes a fixed end 101 at the bottom and a reflective end 102 above the fixed end 101. The cross-section of the reflective end 102 is an isosceles trapezoid. The isosceles trapezoidal reflective end 102 and the surface corresponding to the radar 2 are provided with an acute-angled protrusion 103. Through such a setting, the acute-angled protrusion 103 can be utilized to increase the reflection intensity, making the corresponding radar 2 signal more obvious.

[0024] The fixed end 101 includes plug-in strips 104 evenly distributed below the reflective end 102, wherein the plug-in strip 104 below the side where the protrusion 103 is not provided is provided with a threaded connection hole 105. Through such a setting, the fixed end 101 can be plugged into the soil or connected to the bracket 3 through a threaded connection component.

[0025] The bracket 3 is divided into a fixed part 301 and a rotating part 302. The rotating part 302 is fixedly installed above the fixed part 301, and the radar 2 is fixedly installed above the rotating part 302. By setting the rotating part 302, the radar 2 can be rotated horizontally, thereby increasing the detection angle between adjacent radars 2.

[0026] The radar 2 includes a signal generating unit 201 for sending signals, a signal receiving unit 202 for receiving reflected signals, a storage unit 203 for storing initial data, a temporary storage unit 204 for temporarily storing collected data, an information comparison unit 205 for comparing the temporarily stored data with the collected data, and an information transmission unit 206 for sending the comparison information. The information transmission unit 206 can be transmitted in a wired or wireless manner. The signal is sent by the signal generating unit 201 and reflected by the reflective substrate 1 to the signal receiving unit 202. The signal receiving unit 202 stores the initial collected signal inside the storage unit 203 and stores the later collected information in the temporary storage unit 204. The information between the two units is compared using the information comparison unit 205, and the comparison result is transmitted to a remote information terminal through the information transmission unit 206.

[0027] An edge 108 is provided at the bottom end of the reflecting end 102, and a through hole 107 is provided on the surface of the edge 108 and the surface of the fixed end 101. The edge 108 and the fixed end 101 are connected by a bolt 106. Through such a setting, the fixed end 101 can be installed first and then the reflecting end 102 can be connected to the fixed end 101, thereby avoiding the need to knock when inserted into hard soil, and the problem that external force can easily cause the reflecting end 102 to be knocked and deformed.

[0028] When in use, multiple reflective substrates 1 are set at any position on the slope, and radars 2 with different frequencies are set on the front and both sides of the slope, and a reflective substrate 1 is also set on the installation part of the radar 2. Multiple radars 2 are used to detect the position of the reflective substrate 1 and store it. The detection information is continuously collected for comparison, so that the movement of the slope can be detected in time. At the same time, after the radar 2 is displaced, it can be detected by the adjacent radar 2, avoiding false information caused by the displacement of the radar 2.

[0029] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
