Description

Technical Field

[0001] This utility model relates to the field of salt lake water level monitoring technology, and in particular to an online salt lake water level monitoring system. Background Technology

[0002] In today's salt chemical industry, salt lake water level data is a critical process parameter in specific production processes. Due to the unique environmental conditions of salt lakes (large waves, brine prone to salt formation, and solid-liquid stratification), traditional remote sensing and immersion sonar measurement methods suffer from low data accuracy and poor system stability. To ensure the high-precision real-time acquisition of water level data required by production processes, manual measurement is often used. However, manual measurement is inefficient and yields low-accuracy data. Therefore, the need for an online salt lake water level measurement device specifically designed for the unique conditions of salt lakes has arisen. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] An online monitoring system for salt lake water levels includes a first elevation measuring device, a float, and a second elevation measuring device. The first elevation measuring device is fixed to a salt lake depth benchmark on the shoreline of the salt lake to obtain the elevation at a fixed location. The float is used to float on the surface of the salt lake. The second elevation measuring device is fixed to the float to obtain the elevation at its location.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The purpose of this invention is to provide an online monitoring system for salt lake water levels to solve the problems existing in the prior art. It can realize real-time monitoring of salt lake water levels, and the monitoring data is accurate. It solves the problems of high labor intensity, low measurement efficiency and low measurement data accuracy caused by manual measurement.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1-4 As shown, this embodiment provides an online monitoring system for salt lake water levels, including a first elevation measuring device, a float 1, a second elevation measuring device, and a controller. The first elevation measuring device is fixed to a salt lake depth benchmark on the shoreline to obtain the elevation Mm at a fixed location. The float 1 floats on the surface of the salt lake. The second elevation measuring device is fixed to the float 1 to obtain the elevation Xm at its location. The distance Ym between the second elevation measuring device and the surface of the float 1 is known (based on the density of the salt lake water and the mass and volume of the float 1 minus the second elevation measuring device). The system also includes a controller, which is communicatively connected to the first and second elevation measuring devices, acting as a terminal for both devices to summarize the measured data.

[0030] During the construction of the salt lake, there will be known design depth data Nm. According to the online monitoring system for salt lake water level in this embodiment, the first elevation measuring device is placed at the reference point relative to the design depth data of the salt lake, and the elevation Mm (elevation of the top surface of the salt lake) - Nm (design depth of the salt lake, i.e., the distance from the top surface of the salt lake to the bottom of the salt lake) = Hd (elevation of the bottom of the salt lake) is measured. The second elevation measuring device can measure the elevation Xm of its location. The distance Ym between the second elevation measuring device and the surface of the float 1 is known, Xm - Ym = Zm (elevation of the salt lake water level line). With Zm and Hd, Hm (water level, i.e., the distance from the salt lake water level line to the bottom of the salt lake) = Zm - Hd can be obtained, thereby realizing real-time monitoring of the actual water level.

[0031] Therefore, the online monitoring system for salt lake water level in this embodiment can realize real-time monitoring of salt lake water level, and the monitoring data is accurate, solving the problems of high labor intensity, low measurement efficiency and low measurement data accuracy caused by manual measurement.

[0032] This embodiment also includes a third elevation measurement device that communicates with the controller. This third elevation measurement device is fixed to the shoreline of the salt lake. Both the first and third elevation measurement devices are RTK (Real-Time Kinematic Base Station) reference stations, while the second elevation measurement device is an RTK rover. Both the RTK reference station and the RTK rover have built-in antennas, enabling them to connect to satellite systems (such as BeiDou) to obtain the elevation of the set location. In practical use, after calibrating the bottom elevation Hd of the salt lake using the first elevation measurement device, it can be used as the third elevation measurement device, which can be fixed at any position on the shoreline. The RTK reference station of the third elevation measurement device, used in conjunction with the RTK rover, compared to using the RTK rover alone, can eliminate common errors through differential technology, significantly improving positioning accuracy (from meter-level to centimeter-level), thereby improving the accuracy of monitoring data and enhancing the adaptability and reliability of the application scenario.

[0033] RTK base station, RTK rover station and controller are all commonly used devices in the field. The working principle and data transmission method of RTK base station and RTK rover station are well known to those skilled in the art, and will not be described in detail in this embodiment.

[0034] In this embodiment, the float 1 includes a base 2 and a main body 3 fixed to the base 2. An RTK rover is fixed to the top of the main body 3. The base 2 needs to be partially or completely submerged in the salt lake. It can be made of stainless steel sealed enclosure, and the outer surface of the stainless steel sealed enclosure is provided with an anti-rust paint layer to prevent rust, reduce salt water corrosion, and extend the service life of the float 1.

[0035] In this embodiment, the cross-sectional dimensions of the main body 3 gradually increase from top to bottom; the main body 3 can be a frustum, pyramid, cone, or pyramid shape, with a low center of gravity and a high center of buoyancy, which can generate a restoring torque when swaying, reducing the possibility of it overturning in wind and waves, and ensuring the stable operation of the monitoring work.

[0036] In this embodiment, the main body 3 of the float 1 includes a shell, the bottom of which is fixedly connected to the top of the stainless steel box, specifically by bolts; a spherical shell 4 made of fiberglass is fixed to the top of the shell, and an RTK rover is placed inside the spherical shell 4 to protect the RTK rover; the shell is filled with a filler material, which is a lightweight material such as polyurethane foam.

[0037] Any adaptive changes made according to actual needs are within the protection scope of this utility model.

[0038] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
