Abstract

The invention relates to a monitoring device for a mechanism of influence of deep and large reservoir construction on water temperature, and a monitoring method of the monitoring device. The device comprises an automatic water temperature monitoring station, a communication system and a data monitoring center; the automatic water temperature monitoring station comprises a water temperature sensor, an RTU controller, a communication device, a waterproof signal cable and the like; a solar panel is connected with the RTU controller through a solar charging controller; the water temperature sensor is connected with the RTU controller through the waterproof signal cable; and the like. By adopting the device disclosed by the invention, the water temperature monitoring is not influenced by severe weather and water-electricity operation / dispatching; the temperature values of water layers with different depths can be obtained continuously; the personal safety hazards are not caused to researchers; the technical guidance can be provided for lake and reservoir water quality and environment and water ecological system protection, lake and reservoir fishery management and control, and the like; and important guidance is provided for lake and reservoir ecological scheduling, water conservancy and hydropower project ecological regulation, ecological agriculture irrigation and the like.

Description

technical field [0001] The invention belongs to the technical field of the structure of an automatic monitoring device for water temperature of a deep and large reservoir, and relates to the technical field of a method for using the automatic monitoring device. Background technique [0002] After the construction of hydropower stations and dams (reservoirs), it is necessary to regularly monitor the temperature of the water layer at a certain point in time, at a certain location, and at a certain depth, in order to obtain more hydrological data. There is no ready-made system / device for measuring its water temperature, let alone a complete monitoring method. Usually, the boat is manually driven to the monitoring site, and then put into the water temperature monitoring equipment. After the measurement and recording, the water temperature monitoring equipment is salvaged ashore. This method is very unsafe, and it is basically impossible to sail the boat out when the dam is hydr...

AI Technical Summary

Problems solved by technology

This method is very unsafe, and it is basically impossible to sail the boat out when the dam is hydropower generating. Because a large amount of water in the middle or lower part of the side of the dam body tilts out, the flow velocity below the water surface is very violent and very It is easy to cause a vortex situation, and it is easy to cause casualties or damage to personnel or equipment due to some unexpected reasons

Therefore, it is only possible to go out for monitoring when the hydropower stops running and wait until the operation is dispatched.

In addition, one or more measurements cannot continuously give data, which is not conducive to hierarchical measurement; if a set of continuous values ​​needs to be measured, researchers need to go to mountainous valleys for monitoring every month, and the cost is very high; In the event of bad weather such as rain, scientific research cannot be carried out, so the continuity of the measured data is very poor, and it is difficult to fully explain the law of water temperature changes when used as first-hand data research, let alone give important insights into hydropower ecological scheduling.
