[0016] The beneficial effects of this utility model's dam settlement monitoring device are as follows: In practical application, the support column can be installed on the upper end of the foundation, and the support assembly can be installed on the upper end of the dam body.

Furthermore, because a connecting rod connects the support column and the installation column, the installation column and the support column are also relatively fixed, and consequently, the installation column and the foundation are also relatively fixed. Moreover, because the support assembly is connected to the lower end of the sliding rod, the support assembly and the sliding rod are relatively fixed. Therefore, when settlement occurs in the dam body or foundation, the sliding rod will... The mounting column slides up and down, causing the detection rod to move between two detection blocks. This allows the corresponding detection part to contact the detection block and trigger a detection signal, thus achieving settlement monitoring. Because the two adjusting plates are mounted on the adjusting rod vertically, the vertical distance between the two detection blocks is adjustable. This means that the vertical displacement of the detection rod when the detection signal is triggered can be adjusted, i.e., the settlement trigger distance is adjustable. Therefore, the settlement trigger distance can be adjusted to change the alarm threshold when facing different geological conditions and dam structures, avoiding false alarms or missed alarms, and thus improving the reliability of monitoring results.

[0023] This utility model provides a dam settlement monitoring device, which will be described in detail below with reference to specific embodiments.

[0024] like Figure 1 and Figure 2As shown in the figure, a dam settlement monitoring device provided by this utility model includes a support column 1, an installation column 2, an adjustment component 3, a sliding component 4, a detection rod 5, and a support component 6. The support column 1 and the installation column 2 are arranged side by side and connected by a connecting rod 11. The support column 1 is used to install on the upper end of the foundation. The adjustment component 3 includes an adjustment rod 31 and two adjustment plates 32. The adjustment rod 31 is located on the support column 1 and is vertically arranged. The two adjustment plates 32 are respectively provided with detection blocks 321. The sliding assembly 4 is movably mounted on the adjusting rod 31; the sliding rod 41 is slidably mounted on the mounting column 2; one end of the detection rod 5 is connected to the sliding rod 41, and the other end extends between the two detection blocks 321. The detection rod 5 has detection parts 51 on both sides near the two detection blocks 321, and the detection parts 51 are used to contact the detection blocks 321 to trigger a detection signal; the support assembly 6 is connected to the lower end of the sliding rod 41 and is used to be installed on the upper end of the dam body.

[0025] Specifically, the distance between the detection rod 5 and the two detection blocks 321 can be equal, that is, the detection rod 5 is located in the middle of the space between the two detection blocks 321. Specifically, the detection part 51 can be provided at the end of the detection rod 5 that extends between the two detection blocks 321. In addition, the support column 1 can be fixedly installed on the upper end of the foundation by means of, for example, bolt connection, and the support assembly 6 can also be fixedly installed on the upper end of the dam body by means of, for example, bolt connection.

[0026] In this embodiment, when the dam settlement monitoring device is actually applied, the support column 1 can be installed on the upper end of the foundation and the support assembly 6 can be installed on the upper end of the dam body. In this way, the support column 1 is relatively fixed to the foundation, and the support assembly 6 is relatively fixed to the dam body. Furthermore, because a connecting rod 11 connects the support column 1 and the mounting column 2, the mounting column 2 is also relatively fixed to the support column 1, and thus the mounting column 2 is also relatively fixed to the foundation. Moreover, because the support assembly 6 is connected to the lower end of the sliding rod 41, the support assembly 6 and the sliding rod 41 are relatively fixed. Thus, when the dam body or foundation settles, the sliding rod 41 will move relative to the mounting column 2. The sliding motion causes the detection rod 5 to move between the two detection blocks 321, making the corresponding detection part 51 contact the detection block 321 to trigger a detection signal and achieve settlement monitoring. Because the two adjustment plates 32 are respectively installed on the adjustment rod 31, the vertical distance between the two detection blocks 321 is adjustable. This means that the vertical displacement of the detection rod 5 when triggering the detection signal can be adjusted, that is, the settlement trigger distance is adjustable. Therefore, when facing different geological conditions and dam structures, the settlement trigger distance can be adjusted accordingly to change the alarm threshold, avoid false alarms or missed alarms, and thus improve the reliability of the monitoring results.

[0027] Optionally, such as Figure 2 and Figure 3 As shown, the adjusting rod 31 is rotatably mounted on the support column 1 around its own axis. The side wall of the adjusting rod 31 is provided with two threaded sections 311 that are spaced apart vertically, and the two threaded sections 311 have opposite directions of rotation. The two adjusting plates 32 are respectively slidably mounted on the support column 1 and are threadedly connected to the two threaded sections 311 respectively.

[0028] Specifically, the upper end face of the adjusting rod 31 is provided with a hexagonal groove so that a tool can be inserted to screw the adjusting rod 31.

[0029] In this optional embodiment, when the adjusting rod 31 is rotated, since the adjusting plate 32 can be slidably installed on the support column 1 and the adjusting plate 32 is threadedly connected to the threaded section 311, the adjusting plate 32 will move vertically. Furthermore, since the two threaded sections 311 have opposite rotation directions, the two adjusting plates 32 will also move in opposite directions under the action of the adjusting rod 31. That is, the two adjusting plates 32 will move in opposite directions or towards each other vertically, ultimately achieving adjustable vertical spacing between the two detection blocks 321. This solution uses a threaded connection to install the adjusting plate 32. When there is no external force, the adjusting plate 32 will not move down on its own, which can ensure the positional stability of the detection block 321 and avoid accidental contact between the detection block 321 and the detection part 51.

[0030] Optionally, such as Figure 2 and Figure 4 As shown, the support column 1 is provided with a rotating hole 12 and a sliding groove 13 connected vertically. The side wall of the support column 1 is provided with a connecting groove 14 communicating with the sliding groove 13. The adjusting rod 31 is rotatably engaged with the rotating hole 12 and the two threaded sections 311 extend into the sliding groove 13. The two adjusting plates 32 are respectively slidably engaged with the sliding groove 13 and the two detection blocks 321 extend into the connecting groove 14. The end of the detection rod 5 near the adjusting rod 31 is located in the connecting groove 14.

[0031] Specifically, two threaded sections 311 are located at the lower part of the adjusting rod 31, with the upper part of the adjusting rod 31 located in the rotating hole 12 and the lower part located in the sliding groove 13. In addition, the cross-section of the sliding groove 13 can be square, and the adjusting plate 32 can be a square plate adapted to the shape of the sliding groove 13.

[0032] In this optional embodiment, the adjusting rod 31 is rotatably engaged with the rotating hole 12 and the two threaded sections 311 extend into the sliding groove 13. The two adjusting plates 32 are slidably engaged with the sliding groove 13 respectively. Thus, the entire adjusting assembly 3 is located inside the support column 1, which can protect the adjusting assembly 3. In addition, the two detection blocks 321 extend into the connecting groove 14, which means that the detection part 51 located between the two detection blocks 321 is also located in the connecting groove 14. Thus, the detection blocks 321 and the detection part 51 are both located inside the support column 1, which can isolate the detection blocks 321 and the detection part 51 from the outside world and prevent accidental activation.

[0033] Optionally, such as Figure 2 and Figure 4 As shown, the side wall of the support column 1 is provided with a mounting groove 15, and an electrical box 7 is installed in the mounting groove 15. The electrical box 7 is electrically connected to the detection block 321 and the detection part 51 respectively.

[0034] In this optional embodiment, the detection block 321 and the detection unit 51 form a circuit after contact, and the generated detection signal can be processed by the electrical box 7 and then sent to the outside.

[0035] Furthermore, the electrical box 7 can be electrically connected to an external warning device. The signal processed by the electrical box 7 is sent to the warning device, which then issues an alert to remind the staff.

[0036] Optionally, such as Figure 2 and Figure 4 As shown, the mounting column 2 has a vertically penetrating mounting channel 21, and the side wall of the mounting column 2 has a connecting groove 22 that communicates with the mounting channel 21; the sliding rod 41 is slidably engaged with the mounting channel 21; and the detection rod 5 passes through the connecting groove 22.

[0037] In this optional embodiment, the sliding rod 41 is slidably engaged with the mounting channel 21, that is, the sliding rod 41 can be slidably mounted on the mounting post 2, so that the sliding rod 41 can be protected inside the mounting post 2.

[0038] Optionally, such as Figure 2 , Figure 4 and Figure 5 As shown, the mounting channel 21 includes a mounting hole 211 and a limiting groove 212 formed on the inner wall of the mounting hole 211. The communicating groove 22 communicates with the limiting groove 212. The sliding rod 41 is slidably engaged with the mounting hole 211. The side wall of the sliding rod 41 is provided with a limiting plate 411 that extends into the limiting groove 212. One end of the detection rod 5 is connected to the limiting plate 411, and the other end passes through the limiting groove 212 and the communicating groove 22 in sequence and extends to the outside of the mounting post 2.

[0039] In this optional embodiment, when the sliding rod 41 slides up and down along the mounting hole 211, the limiting plate 411 will be limited by the upper and lower groove walls of the limiting groove 212, so that the limiting plate 411 will not come out of the limiting groove 212 in the vertical direction, thereby ensuring that the sliding rod 41 will not come out of the mounting hole 211.

[0040] Optionally, such as Figure 2 , Figure 4 and Figure 5 As shown, the sliding assembly 4 also includes two springs 42 sleeved on the sliding rod 41. One of the two springs 42 is located between the upper groove wall of the limiting groove 212 and the limiting plate 411, and the other is located between the lower groove wall of the limiting groove 212 and the limiting plate 411.

[0041] Understandably, when subjected to an external impact, the sliding rod 41 will slide along the mounting hole 211, causing the detection rod 5 to move vertically. In this optional embodiment, two springs 42 can generate elastic force, which drives the sliding rod 41 to reset in time through the limiting plate 411, thereby eliminating the vertical displacement of the detection rod 5 and ensuring the accuracy of monitoring.

[0042] Optionally, such as Figure 2 and Figure 5 As shown, the support assembly 6 includes a support rod 61 and a support plate 62. The upper end of the support rod 61 is threadedly connected to the lower end of the sliding rod 41, and the support plate 62 is connected to the lower end of the support rod 61 for installation on the upper end of the dam body.

[0043] In this optional embodiment, since the upper end of the support rod 61 is threadedly connected to the lower end of the sliding rod 41, the height of the support plate 62 can be changed when the support rod 61 and the sliding rod 41 rotate relative to each other, thereby adapting to scenarios where there is a height difference between the dam body and the foundation.

[0044] Optionally, such as Figure 2 and Figure 5 As shown, the lower end of the sliding rod 41 is provided with an inner hole 412, and the upper end of the support rod 61 is inserted into the inner hole 412 and its side wall is threadedly engaged with the inner wall of the inner hole 412.

[0045] Specifically, the axis of the inner hole 412 coincides with the axis of the sliding rod 41.

[0046] In this optional embodiment, by inserting the upper end of the support rod 61 into the inner hole 412 of the sliding rod 41 for threaded connection, the internal space of the sliding rod 41 can be effectively utilized, thereby improving the structural compactness of the device.

[0047] Optionally, such as Figure 2 and Figure 5As shown, the support assembly 6 also includes a fastening nut 63, which is threaded to the support rod 61 and its upper end face abuts against the lower end face of the sliding rod 41.

[0048] Specifically, the lower end face of the sliding rod 41 can be located below the lower end face of the mounting post 2 so that the fastening nut 63 can smoothly abut against the lower end face of the sliding rod 41.

[0049] In this optional embodiment, by tightening the nut 63, after the height of the support plate 62 is adjusted, the nut 63 can be screwed so that its upper end face abuts against the lower end face of the sliding rod 41, thereby locking the height position of the support plate 62 and ensuring the stability of the height of the support plate 62 after adjustment.

[0050] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
