Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water temperature measurement, in particular to a layered water temperature measuring device for engineering measurement. Background Art
[0002] Temperature changes can cause changes in the volume of objects, which in turn cause structural deformation. In the fields of buildings, bridges, etc., this deformation may have a significant impact on the long-term stability and integrity of the structure. The bridge pier structure is an important part of the bridge, bearing the weight of the bridge superstructure and the transferred load. The bridge pier structure is often in direct contact with the water environment and is directly affected by changes in water temperature. Especially in water bodies such as rivers and lakes, seasonal changes in water temperature and stratification may have a significant impact on the bridge pier structure. The importance of stratified water temperature measurement to the safety of building structures, especially bridge pier structures, is self-evident. Layered water temperature measurement can help us better understand the impact of water temperature changes on the structure, promptly discover and solve potential problems, and ensure the safety and stability of the structure.
[0003] At present, the traditional solution for measuring water temperature in layers is: multiple water gauges are laid out in the water, and temperature sensors are laid out at the zero elevation of each water gauge, the temperature at the zero point of each water gauge is measured in real time, and a temperature elevation distribution curve is drawn. According to the real-time water level, the temperature at the preset underwater position is linearly interpolated on the temperature elevation curve to obtain the layered water temperature. For measuring the water temperature at the bridge pier, the temperature is currently measured by manually extending the thermometer below the water surface.
[0004] When water gauges are placed in the water and temperature sensors are set at different heights of the water gauges to measure water temperature in layers, although real-time measurement is possible, the water gauges are easily affected by external factors, and some bridge piers are not convenient for setting water gauges, so manual layered water temperature measurement cannot be replaced. However, the current temperature measuring device has a difficult-to-control measurement depth, which can easily lead to low depth accuracy when measuring water temperature in layers, and low reliability of water temperature measurement data in each layer.
