Description
Technical field
The invention belongs to hydraulic engineering technical field, more particularly to a kind of water conservancy reservoir investigation and sampling device and its sampling side
Method.
Background technology
Reservoir, in general be construed to " water conservancy structure of flood retention water storage and regulation current, can utilize to irrigate,
Generate electricity, control flood and breed fish." it refers to build the artificial lake that barrage is formed at the narrow orifice in gully or river.Reservoir is built up
Afterwards, flood control, catchwork irrigation can be played, water supply, generate electricity, breed fish.Sometimes natural lake is also referred to as reservoir (natural storage).Water
Storehouse scale is generally divided by storage capacity size, is divided into small-sized, medium-sized, large-scale etc..Some reservoirs are the main sources of urban water supply, because
This requirement to water quality is very high, and mostly at present is to carry out assessment monitoring to the water quality of reservoir using the method for sample examination, it is ensured that
Water safety.
As patent announcement CN203164014U discloses a kind of hydrophore suitable for a variety of depth of waters, wherein handle is installed
On water acquisition container, release drawstring is connected on handle, and the top of top cover labyrinth and water acquisition container is rotatably connected and closure
It is located on the top of water acquisition container, the bottom of lower sealing cover and water acquisition container is rotatably connected and closure is located at water acquisition container
