Description
Technical field
This utility model relates to intake pollution clean-up technology field, power station, takes for power station in particular to one
The sewage blocking device at the mouth of a river.
Background technology
Power station dirt-blocking dirt-cleaning scheme enjoys the concern of insider all the time, and it directly affects energy loss, generating
Benefit, operating cost etc.；The when that especially wet season unit standard-sized sheet completely being sent out, trees that upstream river surface drifts about, branch, tree
The foreign material such as root are piled up before trash rack and are affected unit output, and branch, tree root are often stuck trash in addition, and trash can not
Run well.
Therefore remove before trash rack rubbish to reduce the loss of flood peak, improve unit output, guarantee unit safety, less abandon water,
Many generatings increase economic benefits of power generating important role.
The most conventional mode of removing contamination is: typically arranges one trash rack at powerplant intakes, and configures trash, clearly
Reason accumulates in the dirt before trash rack, but it exists following defect:
(1) a lot of because of slags such as the trees of main stem, branch, tree roots, most slags are drawn onto clearly by flume tunnel flow water suction force
On dirty machine grille (being the most just that trash salvages dead band), causing inflow to be obviously reduced, unit institute on-load reduces to specified
Value, even adheres to many when the foreign material on grille, and load does not also reach rated value, and if wanting scarfing cinder to must shut off stator and reduce
Unit load recoils, and recoil deslagging about needs 30-40 minute every time；
(2) slag such as trees, branch, tree root is often stuck for trash, and trash can not run well, it is necessary to emptying reservoir area
Water is cleared up, and reduces power plants generating electricity benefit；
(3) especially when the wet season, foreign material directly rush at water inlet under rapid stream effect and clash into trash,
Trash grid phyllomorphosis is easily caused not run well, it has to emptying reservoir area water carries out clearing up and repairing trash.
Utility model content
In order to solve the problems referred to above, the purpose of this utility model is to provide a kind of dirt of blocking for power station intake to fill
Put, to block the foreign material in river course, and prevent foreign material to be attached to sewage blocking device, thereby may be ensured that trash is not stuck, increase
Add power benefit.
The technical scheme that this utility model is used is:
A kind of sewage blocking device for power station intake, it includes framework and parallel along the longitudinal direction of described framework
The many sheet gratings leaf arranged；Described grid leaf is fixing with described framework to be connected, and the grid face of described grid leaf is flat with what described framework surrounded
Face setting at an acute angle, and the water (flow) direction of the grid face main stem dorsad of described grid leaf.
During installation, above-mentioned sewage blocking device is arranged at the 2-3m of trash upstream at intake, passes through sewage blocking device
Grid leaf block the foreign material in river course；Meanwhile, by the grid face setting at an acute angle with the plane that framework surrounds making grid leaf, and grid
The water (flow) direction of the grid face main stem dorsad of leaf, makes the water conservancy diversion direction of grid leaf and the water (flow) direction adverse current of main stem, such that can
So that the current in river course flow through draws dirty device, the foreign material blocked by grid leaf can be made again to downstream by the current band of main stem
Avoiding foreign material to be attached in sewage blocking device affects inflow, thus it is guaranteed that trash is not stuck, adds power benefit.
Further, the width of described grid leaf is 15-20cm；The spacing of grid leaf described in adjacent two panels is 25-30cm；Described grid
The plane that the grid face of leaf and described framework surround is that 45° angle is arranged.
By the width of grid leaf is set to 15-20cm, i.e. ensure that the refluence effect of grid leaf, saved again the consumption of grid leaf
Material；Meanwhile, the spacing of adjacent two sheet grating leaves is 25-30cm, and the plane making the grid face of grid leaf and framework surround is 45° angle, this
Sample, is i.e. possible to prevent the foreign material such as the trees in river course, branch, tree root by sewage blocking device, can ensure that again enough water inlets
Amount.
Further, described framework includes frame and along being perpendicular to the some fixed transverse rods that described grid leaf is arranged, described
The two ends of cross bar are fixing with described frame respectively to be connected, and described grid leaf is fixed with described cross bar and is connected.
In order to improve the bulk strength of sewage blocking device, it is preferable that be also provided with some with fixing horizontal stroke between the frame of framework
Bar, it i.e. can play booster action with opposite side frame, and can also increase the fixing point of grid leaf, and therefore, dirt is blocked in beneficially raising
The bulk strength of device.
Wherein, the quantity of fixed transverse rod the most then causes the intensity of sewage blocking device not reach standard；And the number of fixed transverse rod
Amount not only can affect inflow too much, but also can increase cost, and therefore, the quantity of fixed transverse rod is preferably three.
The beneficial effects of the utility model:
Sewage blocking device for power station intake provided by the utility model, by the many sheet gratings being arranged on framework
Leaf blocks the foreign material in river course；Meanwhile, by by setting at an acute angle with the plane that framework surrounds for the grid face of grid leaf, and its water conservancy diversion
The water (flow) direction adverse current of direction and main stem, thus can be able to make by grid again so that current in river course flow through and draw dirty device
The foreign material that leaf blocks are avoided foreign material to be attached in sewage blocking device by the current band of main stem to downstream affecting inflow, therefore,
Ensure that trash is not stuck, add power benefit.
