Description

Technical Field

[0001] This utility model relates to the field of channel deformation monitoring, and in particular to a channel bottom settlement detection device. Background Technology

[0002] The settlement monitoring points for the South-to-North Water Diversion Canal, located 6-7 meters underwater, are crucial for the shield tunnel. The installation of monitoring components must not damage the canal structure or pollute the water, and they must be easily disassembled, transported, and maintained. This places high demands on the monitoring system's waterproofness, environmental friendliness, reliability, and corrosion resistance. A portable digital barcode ruler disclosed in patent document CN219367343U is susceptible to the influence of canal water flow during use, making it difficult to provide stable support and ultimately leading to measurement distortion.

[0003] A channel bottom settlement detection device is provided to solve the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a channel bottom settlement detection device, which effectively solves the problems of the prior art that require the measuring ruler to be placed vertically in the water, the support is unstable, and it is easily affected by water flow.

[0005] The technical solution includes a long shaft that spans the river channel, with bases at both ends of the long shaft. The bases are fixed to the riverbank, and the long shaft is rotatably mounted on the bases. An angle sensor is installed on the base, which can measure the angle of rotation of the long shaft. A downward-sloping boom is fixed in the middle of the long shaft, and a counterweight is at the lower end of the boom. The bottom of the counterweight is placed at the bottom of the channel.

[0006] Furthermore, the counterweight is a roller, and the lower edge of the roller contacts the bottom of the channel.

[0007] Furthermore, the base is fixed to the riverbank with multiple screws.

[0008] This invention has a clever structure. Unlike traditional methods, this solution does not require placing the measuring ruler in the water. It measures channel settlement by turning the angle, resulting in more accurate measurement results. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the overall design of this utility model.

[0010] Figure 2 This is the front view of the present utility model.

[0011] Figure 3 This is an exploded view of the present invention.

[0012] Figure 4 This is a diagram showing the state of the boom in its initial state according to this utility model. Detailed Implementation

[0013] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0014] Depend on Figures 1 to 4 As shown, this utility model includes a long shaft 2 that is horizontally mounted on a river channel 1. The long shaft 2 has bases 3 at both ends. The bases 3 are fixed on the banks of the river channel 1. The long shaft 2 is rotatably mounted on the bases 3. An angle sensor is installed on the bases 3, which can measure the rotation angle of the long shaft 2. A downwardly inclined hanging rod 4 is fixed in the middle of the long shaft 2. A counterweight 5 is located at the lower end of the hanging rod 4. The bottom of the counterweight 5 is placed at the bottom of the channel.

[0015] In order to ensure that the boom 4 is in constant contact with the bottom of the channel, the counterweight 5 is a roller, and the lower edge of the roller is in contact with the bottom of the channel.

[0016] The base 3 is fixed to the riverbank with multiple screws.

[0017] This approach breaks with traditional methods by using angle variation to measure the settlement at the bottom of the channel. Compared to traditional laser signal measurement, this method is less difficult and more accurate.

[0018] In use, the initial state is as follows Figure 1 , 4 As shown, the boom 4 is tilted downwards, and the roller at the lower end of the boom 4 is placed at the bottom of the river channel 1. The angle sensor on the base 3 is zeroed. If the channel settles, the tilt angle of the boom 4 will change. The angle sensor can obtain the angle of rotation of the long axis 2. Given the angle and the length of the boom 4, the settlement parameters can be calculated.

[0019] This invention has a clever structure. Unlike traditional methods, this solution does not require placing the measuring ruler in the water. It measures channel settlement by turning the angle, resulting in more accurate measurement results.
