Self-adapting measuring device and method for water temperature of reservoir

Abstract

An adaptive measuring device for the water temperature of a reservoir, comprising: a probe (15), a fixed pulley (14), a lifting control device (12), a control system (1) and a data transmission line (13), wherein one end of the data transmission line (13), after twining the lifting control device (12), is connected to the control system (1), and the other end thereof is connected to the probe (15) through the fixed pulley (14) fixed above the reservoir. A microprocessor (2) in the control system (1) performs calculation according to input parameters, a selected measurement mode and data transferred back, and issues an instruction to make the lifting control device (12) act, thereby enabling the length of the data transmission line (13) entering the reservoir to change so as control the lifting of the probe (15) for measuring. Also provided is an adaptive measuring method for the water temperature of a reservoir. The provided adaptive measuring device and measuring method for the water temperature of a reservoir can realize efficient, rapid and accurate measurement of the water temperature of the reservoir, and capture the change of a thermocline well.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and relates to an adaptive measuring device and a measuring method for water temperature of a reservoir. Background technique [0002] After the reservoir is built, the water flow velocity in the reservoir area will decrease, the water body replacement cycle will increase, and the heat transport process of the water body will change greatly, which will form its unique water temperature structure. For example, reservoir water temperature stratification may directly lead to water quality stratification and ecological stratification in the reservoir area, and it will affect farmland irrigation, industrial water supply, domestic water, water quality and ecological balance of downstream rivers, and water utilization in the reservoir area (breeding, entertainment) etc. have important influences. Water temperature is an extremely important factor in the water environment, an important param...

Problems solved by technology

However, due to the uncertain location of the thermocline or thermocline, the encrypted measurement points are not necessarily in the area where the thermocline or thermocline occurs, which often results in a waste of manpower and material resources

At the same time, the point thermometer can only be manually sampled and measured at each point, which is time-consuming and labor-intensive.

Some research institutions use the Hydrolab DS5 multi-parameter water quality detector produced in the United States to measure water temperature, but this instrument must be placed on a fixed section for a long time, which may cause damage to the instrument. At the same time, the measurement range is limited and the cost is high. Therefore, it is urgent to provide a low-cost , can save manpower and material resources, reduce the number of measurement points as much as possible, and can better capture the water temperature measurement device and method of the deep water reservoir water temperature change trend
