Layered water-taking water-temperature observation device of reservoir stop log gate and observation method of same
The invention discloses a layered water-taking water-temperature observation device of a reservoir stop log gate and an observation method of the same, which belong to the technical field of water resources and hydropower engineering. The device comprises a water inlet, wherein a trash rack, a stop log gate and an electricity-generation water inlet horn mouth section are disposed at the water inlet, the trash rack is located in front of the water inlet, the stop log gate is located in the water inlet, the electricity-generation water inlet horn mouth section is located on the downstream side of the water inlet, a before-dam water temperature and water level observation device is disposed on the upstream side of the water inlet, and an after-dam electricity-generation tail water water-temperature observation device is disposed on the downstream side. In the technical scheme, the stop log gate is disposed at the water inlet to realize layered water taking, reservoir surface water enters a water taking duct from the top of the stop log gate of the water inlet, and an opening height of the stop log gate is controlled according to changes of a reservoir water level, so that the water taking from the reservoir surface and electricity generation can be ensured, lower-layer water in a reservoir is avoided from flowing towards the downstream direction and generating harmful influences to a downstream ecological environment, unit independent water supply is realized, and running operations become flexible.
