Framework distance sewage dams the distance of mouth 4 more than being arranged on the side of mouth 4 offside that dams with sewage
Framework distance sewage on wall dams the distance of mouth 4;Even with the direction of drainage flow as vector
X-axis, floating barrier 6 is acute angle with the angle of X-axis;Vertical gathering sill it is provided with on framework;
Described can slide up and down to be arranged in the gathering sill of framework every slag baffle plate both sides, every slag baffle plate
For the platy structure swum on the water surface of hollow, every slag baffle plate with the direction of vertical flow direction
It is arranged in drainage pipeline.Every the platy structure swimming on the water surface that slag baffle plate is hollow, every
It is whole every the 1/2~2/3 of slag height of baffle plate that slag baffle plate swims in the height on the water surface, this
The purpose that sample is arranged is to have enough height when stopping scum silica frost;Every slag baffle plate and current stream
To direction be that certain inclination angle is arranged in Vatch basin, both sides can slide up and down to be connected to framework
In upper gathering sill, so arrange and can ensure that every slag baffle plate with the fixing upper and lower floating movement of track,
Quick in order to increase every slag barrier slides, guide pad is set in the translocation every slag baffle plate, guides
Block two ends are trapezoidal platy structure, it is possible to use multiple material is made, and are designed as trapezoidal
Structure is conducive to directly to slide in gathering sill every slag baffle plate when installing every slag baffle plate, is beneficial to peace
Dress maintenance.Can focusing on most scum silica frost interception one side later stage together.Guide pad
On be provided with rolling steel ball, the rolling steel ball on guide pad is distributed on three faces, be respectively with
Front, left surface and the right flank (face being connected with every slag baffle plate with guide pad of gathering sill contact
For the back side, the back side is front to opposite, and the left side in front is left surface, and right side is right flank)
On, such guide pad moves in gathering sill exactly in the way of rolling slip.Set on guide pad
Being equipped with the accommodating hole accommodating rolling steel ball, be provided with gland outside accommodating hole, gland is solid by bolt
Being scheduled on guide pad, gland is provided with the diameter through hole less than rolling steel ball diameter, rolling steel ball
End connects support spring, and is connected with the through hole on gland by supporting spring, supports bullet
Spring afterbody is fixed on accommodating hole bottom surface.Such setting can ensure that rolling steel ball always has one
Part is exposed through hole and is connected with gathering sill, it is possible to rotate.The setting of gland facilitates rolling steel
The installation of pearl is changed.By the effect of rolling steel ball, sliding friction is become rolling friction, reduce
Frictional force, adds the agility of slip.Additionally the upper end every slag baffle plate is further fixed on hanger,
Hanger arrange mesh ground be install every slag baffle plate time can with more convenient and quicker, also be beneficial to maintenance every
Slag baffle plate.This scum board 6 available horizontal grid is replaced.Wherein horizontal grate include framework,
Grille strip, cylinder bracket, the second hydraulic jack and rake teeth, the oil cylinder that level is fixed on framework
Support includes fixing end and movable end, between fixing end is vertically fixed on framework below, movable
Totally four, end, is vertically arranged on framework, and the upper and lower side of movable end is slidably connected with framework, and four
Connected by connecting rod between individual movable end.Second hydraulic jack horizontal symmetry is arranged at fixing end two
Side, the cylinder base of oil cylinder is fixed on fixing end, and piston rod is fixed on movable end, along with
The work of the second hydraulic jack, the alternative movable end of piston rod slides along framework level.Rake teeth is longitudinally
It is uniformly distributed on movable end, corresponding with grille strip.
By the operation principle schematic diagram of this patent shown in Fig. 4 to Fig. 6: during fine day,
Dry flow sewage in combined system pipeline flows in Vatch basin, due to the interception function of fixed weir, cuts
Dry flow sewage in stream well can only be discharged by sewage conduct, thus plays the dry flow sewage that dams
Effect;
During rainfall, the early-stage rainwater of early stage is dammed to sewage conduct together with dry flow sewage;
Along with rainfall strengthens, the water level in Vatch basin gradually rises, now, and floating of ball float cut-off equipment
Ball progressively closes off soil pipe under the effect of buoyancy, thus controls to enter the amount of rainfall of sewage conduct,
Later stage rainwater, by fixed weir overflow to downstream line or natural water, meanwhile, floats
Baffle plate lifts along with SEA LEVEL VARIATION, is intercepted in Vatch basin by floating thing, prevents from flowing into downstream
Pipeline or natural water.
When rainfall constantly continues, when water level in the level of tail water is increased beyond Vatch basin, waterpower is floated
Dynamic formula non-return weir gate rises with the rising of water level, and non-return weir gate top is consistently higher than the level of tail water,
Thus prevent pouring in down a chimney of downstream water.
It should be appreciated that the above, detailed description of the invention the most of the present utility model, but
Protection domain of the present utility model is not limited thereto, and any those of ordinary skill in the art exist
In technical scope disclosed by this utility model, the change that can readily occur in or replacement, all should contain
Cover within protection domain of the present utility model.
