Embodiment

[0028] Example: Hongshuihe Longtan Hydropower Station

[0029] Hongshuihe Longtan Hydropower Station is a landmark project for the country to implement the strategy of western development and "power transmission from west to east". It is the backbone project and leading reservoir of Hongshuihe hydropower development. and other comprehensive benefits. The normal storage level of Longtan Hydropower Station reservoir is 375m, the corresponding storage capacity is 16.21 billion m3, the dead water level is 330m, and the corresponding storage capacity is 5.06 billion m3 3 , the reservoir has annual regulation capacity. The elevation of the crest of the dam is 382m, and the elevation of the bottom of the dam in front of the dam is 210m.

[0030] According to the vertical prediction results of the water body in the reservoir area, it can be known that from December to February each year, the vertical water body of the reservoir is close to the same temperature distribution, and the ...

Abstract

The invention discloses a continuous and automatic observation device for observing the change rule of a reservoir dual thermocline and a method for installing the device. The device comprises a vertically arranged steel tube mounted in a dam body. A steel cable is arranged in the steel tube. The steel cable is provided with a plurality of sets of observation units. Each observation unit comprises two water temperature probes. The steel tube is provided with a plurality of observation holes matched with the water temperature probes. The steel tube is fixedly connected onto the inner wall of the dam body through a plurality of equally-spaced brackets arranged at an equal interval. The top of the steel tube is provided with a driven pulley. The steel cable comes round the driven pulley to be wrapped around a driving pulley at the top of the dam body. The device is stable in structure, strong in durability, high in accuracy, strong in reliability and wide in application range, which is not easily affected by the water flowing / drifting condition.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering monitoring, in particular to a continuous automatic observation device and an installation method for the variation law of double thermocline layers of a reservoir. Background technique [0002] Water temperature stratification in deep-water reservoirs is a common and widely concerned hydropower environmental problem. Reservoir water temperature stratification refers to the regular vertical stratification structure formed by reservoir water temperature after the water level in the reservoir area rises and the flow velocity slows down, the thermodynamic conditions of the water body change. Common stratified reservoirs are vertically divided into thermocline layer, thermocline layer and hysteresis layer: the temperature layer is near the water surface, the water temperature is mainly affected by air temperature and light, and the vertical gradient of water temper...
