Description

Technical Field

[0001] This utility model relates to the field of environmental ecology, and in particular to an experimental device for measuring the three-dimensional water temperature of a large deep reservoir. Background Technology

[0002] Currently, with the continuous development of hydropower cascade projects in major river basins across China, an increasing number of large reservoirs are being built. The construction of these large reservoirs, with their enormous storage capacity, impounds large amounts of water, slowing down the annual water turnover rate in river channels. The heat storage effect of the impounded water alters the original water temperature distribution pattern, creating a stable temperature stratification structure along the depth direction year-round. Since reservoirs utilize water level differences for power generation, their intakes are typically located at lower elevations, drawing water from the lower, colder layers. If the temperature of the water in the reservoir area does not meet the requirements for water use, it will cause a significant reduction in the yield of irrigated crops and adversely affect downstream aquatic organisms, especially high-level consumer fish. Therefore, monitoring the water temperature of the entire reservoir area in large, deep reservoirs can more effectively enable the implementation of corresponding measures to mitigate the adverse effects caused by changes in water temperature.

[0003] Current methods for measuring reservoir water temperature mainly involve measuring the water temperature at the reservoir bank or surface layer. It is difficult to measure the vertical water temperature of the entire reservoir area, especially deep reservoirs (water depth greater than 100m). Utility Model Content

The transport wheel support system includes a transport vessel, a wheel, and a support frame. The data acquisition system includes an intelligent digital display instrument and a portable miniature handheld GPS locator. The level transmitter probe in the sensor system is connected to the first end of a waterproof and ventilated cable, and the temperature transmitter probe in the sensor system is connected to the first end of another waterproof and ventilated cable. The two waterproof and ventilated cables are bundled together and lowered and retracted through a transport wheel support system.
