Description

Technical Field

[0001] This utility model belongs to the technical field of dam settlement monitoring devices or equipment, specifically relating to a settlement observation device. Background Technology

[0002] As a vital national infrastructure, the safe and stable operation of dams is of paramount importance. Settlement deformation is one of the key indicators for assessing the structural behavior and safety status of dams. Currently, in my country's dam safety monitoring field, the commonly used measurement method involves embedding settlement magnetic rings and matching settlement tubes. This method involves pre-embedding settlement tubes with magnetic rings within the dam body or foundation. As the dam body deforms, the magnetic rings move accordingly. A settlement meter is used to measure the position of each magnetic ring relative to a reference point at the tube opening, thereby calculating the cumulative settlement at different elevations.

[0003] However, existing settling meters suffer from significant drawbacks in field data acquisition, including cumbersome operation and difficulty in guaranteeing accuracy. The specific measurement procedure is as follows: the operator must slowly lower the settling meter's sensor into the settling tube. After detecting the magnetic ring position, one hand must hold the side wire connecting the sensor, while the other hand raises the measuring scale to the tube opening, simultaneously meeting two key conditions: first, the line of sight must be strictly parallel to the plane of the settling tube opening; second, the measuring scale must remain vertical and stable during readings. This operation demands a high level of skill and experience from the operator, making it extremely difficult to perform in practice.

[0004] The aforementioned operational difficulties lead to the following two main sources of human error:

[0005] 1. Line of sight error: Since the human eye cannot accurately guarantee that it is completely parallel to the plane of the pipe opening, any slight downward or upward angle will bring significant length measurement error.

[0006] 2. Operational error: During the process of fixing the side line and reading the measuring scale, the measuring scale is very prone to shaking or tilting, resulting in inaccurate readings.

[0007] These random errors introduced by human factors directly affect the reliability, consistency, and accuracy of settlement monitoring data, posing potential risks to the accurate assessment of the dam's safety status. Furthermore, this operational method is inefficient, increasing the labor intensity and duration of fieldwork.

[0008] Therefore, in order to solve the problems of high operational difficulty and high error of manual reading in the existing technology, there is an urgent need to develop a new type of settlement observation device that can simplify operation, automatically align and reduce human error. Summary of the Invention

[0009] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a settling meter observation device that can simplify operation, automatically align and reduce human error.

[0010] The technical solution adopted to solve the above technical problems is: a settlement meter observation device, including an observation bracket, a window plate is provided inside one side wall of the observation bracket, a reflective lens is provided on the surface of the window plate, an auxiliary sight and a rubber roller mounted on a roller bracket are arranged sequentially from left to right inside the observation bracket, the center lines of the auxiliary sight and the rubber roller are located in the same plane and are corresponding to the reflective lens, and the settlement meter is set on the rubber roller through the measuring line.

[0011] The observation bracket of this utility model includes a bracket body, an installation plate is provided in the lower part of the bracket body, an auxiliary sight and a roller bracket are provided on the installation plate, an auxiliary bracket is provided in the lower part of the installation plate, and an observation window is provided on the side wall of the bracket body. The observation window is higher than the installation plate, and the height of the upper edge of the observation window is higher than the top of the auxiliary sight.

[0012] The support body of this utility model is a hollow cylindrical structure, the mounting plate is a circular plate, and the auxiliary support is a hollow cylindrical structure concentric with the support body.

[0013] The bracket body of this utility model has a cable outlet groove on the side opposite to the observation window, and a first cable inlet groove on the side where the bracket body and the observation window form a 90° angle.

[0014] The first inlet slot of this utility model is set to run through the entire height of the bracket body.

[0015] The mounting plate of this utility model is provided with a second cable inlet groove corresponding to the first cable inlet groove, and the auxiliary bracket is provided with a third cable inlet groove corresponding to the first cable inlet groove.

[0016] The auxiliary sights of this utility model are provided in two sets, and the two sets of auxiliary sights are set at intervals.

[0017] The auxiliary sight of this utility model is an isosceles triangular block, with its base fixed to the observation bracket.

[0018] This invention has the following advantages over the prior art:

[0019] 1. This utility model, by incorporating a reflecting mirror, eliminates parallax errors caused by the line of sight not being parallel to the pipe opening, allowing operators to read the scale projected onto the mirror without directly visually viewing the measuring scale. Simultaneously, the aiming system, comprised of an auxiliary sight and rubber rollers, ensures the verticality of the measuring line at the moment of reading, avoiding measurement errors caused by line tilting or swaying, thus significantly improving data accuracy and reliability.

[0020] 2. This invention simplifies the complex, multi-step operation that originally relied on personal skills and experience into two standardized actions: "alignment" and "mirror reading." This design significantly reduces the technical requirements and training costs for operators, enabling even non-professionals to complete measurement tasks quickly and accurately, effectively improving work efficiency.

[0021] 3. This utility model adopts an integrated observation bracket. The design of the inlet and outlet slots makes the installation and guidance process of the survey line extremely smooth, greatly facilitating field use and shortening preparation time. The rubber rollers can effectively transfer the survey line and provide appropriate friction to prevent the survey line from accidentally slipping. Attached Figure Description
