Description

Technical Field

[0001] The utility model relates to a deep displacement monitor. Background Technique

[0002] Traditional dam displacement monitoring methods mainly rely on ground measurement techniques, including leveling measurement, total station measurement, etc. Although these methods have high reliability, they require a large amount of manpower, material resources and time costs, and the monitoring data is greatly affected by the natural environment, making it difficult to obtain accurate and real-time monitoring results. In addition, due to the large size of the dam structure and the wide distribution range of monitoring points, traditional ground measurement techniques cannot meet the comprehensive monitoring requirements of dam displacement, and there are certain limitations in monitoring accuracy and efficiency.

[0003] An application with the publication number CN215261694U proposes a dam displacement monitoring device. This device connects a fixed block to the dam through a fixed rod, and then monitors the distance between the displacement sensor and the fixed block through a distance sensor, thereby realizing the monitoring of dam displacement.

[0004] However, due to the small displacement distance of the dam, simply connecting the fixed rod and the fixed block may cause the distance sensor to fail to timely sense the displacement of the fixed block, resulting in low monitoring sensitivity and further affecting the accuracy of monitoring data. Therefore, a device capable of sensitively monitoring dam displacement is needed to improve the safety of the dam. Content of the Utility Model

[0005] The main object of the utility model is to provide a deep displacement monitor, aiming to solve the above technical problems.

[0007] In one embodiment, the guide wheel group includes a first wheel body and a second wheel body higher than the first wheel body. The first wheel body and the second wheel body are located on the same straight line, so that the direction from the first wheel body to the second wheel body is set in the direction of dam deformation.

[0008] In one embodiment, the first ends of the first wheel body and the second wheel body are rotatably connected to the tube in a lockable manner, and the second ends of the first wheel body and the second wheel body are in sliding contact with the inner wall of the inclinometer tube.

[0010] In one embodiment, the number of the guide wheel groups is multiple, and the multiple guide wheel groups are arranged in parallel at intervals along the height direction of the tube body.

[0011] In one embodiment, the inclination directions of the guide wheel groups of the multiple tube bodies are the same.

[0012] In one embodiment, the inclination directions of the guide wheel groups of at least two tube bodies are different.

[0013] In one embodiment, the connecting rope is indium steel wire, copper wire or nylon wire.

[0014] In one embodiment, a displacement sensor for detecting displacement changes, a data collector for collecting data of the displacement sensor, and a data transmitter for sending the data to a monitoring point are arranged in the tube body.

[0015] In one embodiment, the inclinometer tube is a flexible tube capable of deforming.

[0026] The present utility model provides a deep displacement monitor.

[0027] As Figure 1-2 shown, the deep displacement monitor provided by the embodiment of the present utility model includes an inclinometer tube 10 provided inside the dam and a displacement monitoring assembly 20 provided inside the inclinometer tube 10. The displacement detection assembly includes a connecting rope 21, a plurality of tube bodies 22 provided on the connecting rope 21, and at least one group of guide wheel groups 23 provided on the outer peripheral wall of the tube body 22 and having an inclination angle with the tube body 22.

[0028] In this embodiment, the inclinometer tube 10 is a flexible tube that can deform. The inclinometer tube 10 extends into the dam, and the guide wheel set 23 on the displacement detection assembly has an inclination angle, so that the connecting rope 21 can also respond to the displacement change even when the displacement change is small, generating a displacement sufficient for detection and ensuring the accuracy of displacement monitoring. The structure of this application is simple and easy to use, greatly improving the measurement accuracy.

[0029] It can be understood that a displacement sensor for detecting displacement changes, a data collector for collecting the data of the displacement sensor, and a data transmitter for sending the data to the monitoring point are provided inside the tube body 22. The displacement measuring device is a measuring device cooperating with the connecting rope 21, which can be an existing wire-drawing displacement transmitter or other devices capable of achieving the measurement purpose, and will not be elaborated here. The wire-drawing displacement sensor has a large range and high precision; when the connecting rope 21 moves, it is reflected on the wire-drawing displacement sensor as a change in the voltage value. The GPRS / GSM / 3G data collector performs A / D conversion on the electrical signal, converts it into a digital signal and outputs it, enabling the monitoring personnel to understand the change in the deep displacement of the landslide; this structure is simple, highly adaptable, easy to deploy, the measurement is not affected by the environment, and the observation accuracy is high.

[0030] The GPRS / GSM / 3G data transmitter uses the existing mobile communication network to transmit the signal to the receiver in the data processing center, realizing real-time collection of monitoring data in an unattended environment in the wild and improving work efficiency.

[0031] Please refer to Figure 2 , the guide wheel set 23 includes a first wheel body 231 and a second wheel body 232 higher than the first wheel body 231. The first wheel body 231 and the second wheel body 232 are on the same straight line, and are arranged in the direction of the dam deformation along the direction from the first wheel body 231 to the second wheel body 232. In this embodiment, the first wheel body 231 is located in the X - direction, and the second wheel body 232 is located in the X + direction. The main deformation direction of the dam is the direction from X - to X + (the main deformation direction of the dam can be actively judged by the user or can be the deformation direction that the user hopes to monitor). Therefore, when encountering deformation, it can respond to the displacement change and generate a displacement sufficient for detection.

[0032] Wherein, the first ends of the first wheel body 231 and the second wheel body 232 are rotatably and lockably connected to the pipe body 22, and the second ends of the first wheel body 231 and the second wheel body 232 are in sliding contact with the inner wall of the inclinometer pipe 10. When installing the displacement monitoring assembly 20, the inclination angles of the first wheel body 231 and the second wheel body 232 can be adjusted through the ends of the first wheel body 231 and the second wheel body 232 (a hinged connection method can be adopted) so that the first wheel body 231 and the second wheel body 232 are located on the same straight line. At this time, the second wheel body 232 is higher than the first wheel body 231. The second wheel body 232 is arranged in the X+ direction, and the first wheel body 231 is arranged in the X- direction.

[0033] Wherein, two axially extending chutes 11 are provided on the inner wall surface of the inclinometer pipe 10. The two chutes 11 are symmetrically arranged. The first wheel body 231 and the second wheel body 232 are both slidably arranged in the chutes 11, which can facilitate the installation of the displacement detection assembly. At the same time, the chutes 11 can limit the displacement detection assembly.

[0034] In addition, in order to enable the deep displacement monitor of the present application to simultaneously monitor the displacement changes in different directions, the number of chutes 11 can be increased, and at the same time, the number of guide wheel groups 23 can be increased. The plurality of guide wheel groups 23 are arranged in parallel at intervals along the height direction of the pipe body 22, so that different guide wheel groups 23 are located in different chutes 11 for displacement monitoring in a variety of different directions.

[0035] For example, the first wheel body 231 and the second wheel body 232 of one of the guide wheel groups 23 are respectively arranged on two chutes 11 in the X- and X+ directions, and the first wheel body 231 and the second wheel body 232 of another guide wheel group 23 are respectively arranged on two chutes 11 in the Y- and Y+ directions.

[0036] Wherein, in order to improve the accuracy of displacement deformation, the number of displacement detection components can be increased to obtain multiple data and increase the accuracy.

[0037] In the present application, the inclination directions of the guide wheel groups 23 of the plurality of pipe bodies 22 are the same, or the inclination directions can be different to realize displacement monitoring in at least one direction.

[0038] In the above embodiment, the connecting rope 21 is an indium steel wire; the surface of the indium steel wire is smooth, the thickness is uniform, the tensile strength is large, and the source is wide and the cost is low, which can ensure the sensitivity, practicability and effectiveness in deep monitoring.

[0039] The diameter of the connecting rope 21 is preferably 0.6 mm - 1.2 mm, which is determined according to specific needs. The thinner the connecting rope 21 is, the more connecting ropes 21 can be arranged in the inclinometer tube 10, and the displacement can be determined more accurately. Of course, the connecting rope 21 can also be replaced by copper wire or nylon wire.

[0040] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
