Description
Technical field
A kind of layering water fetching device of no lock control is the utility model is related to, is a kind of water conservancy project device, is a kind of to reservoir
The device of the water layer water intaking of different depth.
Background technology
After reservoir builds up operation, reservoir area water temperature structure is in seasonal stratification state mostly, and water temperature has significantly along depth
The characteristics of layer distributed.Reservoir upper strata is table temperature layer, and water body directly carries out heat exchange with air, and absorption heat energy is more, and temperature is high, layer
Interior water temperature mutually blends, and holostrome temperature is substantially uniform；Lower floor is thermocline, is present in below the water surface in the range of 4 ~ 15m, on holostrome
Lower water temperature change is violent, and thermograde is larger；Most lower is profundal zone, is influenceed by environment's heat smaller, and water temperature is almost unchanged, often
Year maintains relatively stable low-temperature condition.Multiple engineering measurement distribution of water temperature show, Stratified reservoir surface temperature and bottom water
The warm maximum vertical temperature difference is up to 15 ~ 20 ° or so.In view of reservoir thermal stratification have to the ecological environment of reservoir area and downstream it is huge
Big influence, the particularly influence to aquatic ecological, it is more in engineering at present to realize that extraction is different using the method for stratified pumping
The water body of temperature or water quality, to adapt to downstream ecology demand.
Some existing stratified pumping methods include some patents and document, such as：Notification number is " the one of CN203373809
Kind of vertical shaft type layered water drawing structure ", it is stepped in the horizontally disposed intake of different elevations, realize stratified pumping effect.Bulletin

Embodiment ten：
The present embodiment is a kind of method of the stratified pumping using said apparatus.The basic ideas of methods described are：
Positioned at vertically, layering water fetching device is closed the line of inlet opening apopore.Start controller, pass through biography
Motivation structure rotates rotating cylinder, when downstream ecology needs to extract surface water, rotates counterclockwise rotating cylinder, inlet opening is located at two pieces of rectifications
Between plate, reservoir surface water body enters rotating cylinder by water conservancy diversion runner, and is flowed out by another inlet opening, and water body passes through intake stream
Downstream.When needing to extract middle level water body, then continue to rotate counterclockwise rotating cylinder, reservoir middle level water body passes through new water conservancy diversion runner
Corresponding inlet opening enters rotating cylinder, and pass sequentially through another inlet opening, intake flows to downstream.By that analogy, taken according to difference
Water demand, rotate water inlet position.Inlet opening may be alternatively located between two water conservancy diversion runners, adjust each water conservancy diversion runner according to demand
Split ratio.When needing to be stopped, continue to rotate counterclockwise rotating cylinder, inlet opening is located at upright position, then at water fetching device
In closed mode.In addition, when water fetching device needs to extract bottom water body from closed mode, rotating cylinder can be rotated clockwise.
The present embodiment methods described is described in detail below：
During layering water fetching device original state, the line between inlet opening and delivery port is located at plumbness, inlet opening and
For apopore all in buttress, current can not flow through buttress, and layering water fetching device is closed.Between inlet opening and delivery port
Line be located at plumbness this be a kind of original state, you can be considered reset condition, it is also assumed that being after opening
Close.
Stratified pumping instruction and the instruction of water intaking temperature are received, according to the instruction of water intaking temperature, controller obtains rod-type
Thermometer measures to the water temperature of reservoir depth dimension, calculates water intaking depth, and according to the rotation of water intaking depth calculation rotating cylinder
Angle.This is an observing and controlling process, i.e., to carry out the measurement of water temperature gradient, calculates the anglec of rotation of rotating cylinder again.
Here is four kinds of states of water intaking,
Start motor, drum rotation is driven by decelerator, by the detection of angular displacement sensor, reaches calculated rotation
Gyration, then stop, being fetched water, here is four kinds of states of water intaking, the superiors' water body, but orlop water body is taken, in taking
Between water layer water body.Taking the water body of middle aqueous layer also has two kinds of situations：Take the water outlet in a water stream channel completely, or by point
Water ratio takes the water body in two water stream channels simultaneously.
1）When needing to extract reservoir the superiors' water body, inlet opening is between the superiors' cowling panel and buttress, reservoir table
Layer water body enters rotating cylinder by the runner between deflector and buttress, and is flowed out by the apopore on rotating cylinder, flows to downstream.
2）When needing to extract reservoir orlop water body, inlet opening is between orlop cowling panel and buttress, reservoir bottom
Layer water body enters rotating cylinder by the runner between deflector and buttress, and is flowed out by the apopore on rotating cylinder, flows to downstream.
3）When needing to extract reservoir middle level water body, inlet opening is located between middle two layers of cowling panel, makes two pieces of cowling panels
Pointed reservoir middle level water body enters rotating cylinder by the runner between two pieces of deflectors, and passes through the apopore stream on rotating cylinder
Go out, flow to downstream.
4）Or inlet opening is rested on the position of one piece of cowling panel, enable water body above and below the block cowling panel according to point
Water ratio enters rotating cylinder, and is flowed out by the apopore on rotating cylinder, flows to downstream.
When receive stop water intaking instruction when, rotating cylinder rotation, make the line between inlet opening and apopore vertical, water intaking hole and
Apopore is all in buttress, then water fetching device is closed.
It is finally it should be noted that only unrestricted to illustrate the technical solution of the utility model above, although with reference to compared with
The utility model is described in detail good arrangement, it will be understood by those within the art that, can be to this reality
With new technical scheme（Such as the form of honeycomb duct, the form of rotating cylinder water intaking, the motion mode of rotating cylinder water intaking, overall water conservancy project
Form of facility etc.）Modify or equivalent substitution, without departing from the spirit and scope of technical solutions of the utility model.
