The edge of all sides is respectively equipped with semicircular left water fender buckle and right water fender buckle, left water fender buckle and right water fender
Buckle is vertical with left water fender coaming plate and right water fender coaming plate respectively；The side of left water fender coaming plate and right water fender coaming plate both ends
It is respectively equipped with the ring flange of rectangle, ring flange is vertical with left water fender coaming plate and right water fender coaming plate respectively, left water fender coaming plate
It is affixed by ring flange with right water fender coaming plate.
The present invention by adopting the above technical scheme, compared with prior art, beneficial effect is:
Low manufacture cost, simple installation effectively avoid main shaft seal is waterborne from influxing water guide oil basin, avoid influencing unit fortune for a long time
Row, saves time and human cost.
Further, prioritization scheme of the invention is:
It is respectively equipped between left water fender coaming plate and left water fender buckle, between right water fender coaming plate and right water fender buckle multiple
The gusset of triangle.
Ring flange respectively with left water fender buckle and the right ipsilateral setting of water fender buckle.

Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and examples.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of hydraulic turbine main shaft sealing baffle device for water, by water fender coaming plate 1, left water fender buckle
2, right water fender buckle 3, gusset 4 and ring flange 5 are constituted.Water fender coaming plate 1 is annulus subdivision structure, and water fender coaming plate 1 is by a left side
Water fender coaming plate 1-1 and right water fender coaming plate 1-2 is constituted, and left water fender coaming plate 1-1 and right water fender coaming plate 1-2 distinguish semicircular ring
The opening of structure, left water fender coaming plate 1-1 and right water fender coaming plate 1-2 are oppositely arranged.Left water fender coaming plate 1-1 inner periphery side
Edge be welded with semicircular left water fender buckle 2, the edge of right water fender coaming plate 1-2 inner periphery side is welded with semicircle
Right water fender buckle 3, left water fender buckle 2 and right water fender buckle 3 be symmetrical arranged, left water fender buckle 2 and right water fender
Buckle 3 is placed in the ipsilateral of water fender coaming plate 1, left water fender buckle 2 and right water fender buckle 3 respectively with left water fender coaming plate 1-1
It is vertical with right water fender coaming plate 1-2, the medial surface of left water fender buckle 2 and right water fender buckle 3 respectively with left water fender coaming plate
1-1 is concordant with right water fender coaming plate 1-2 inner peripheral surface.
The side at the left both ends water fender coaming plate 1-1 is provided with the ring flange 5 of rectangle, and ring flange 5 and left water fender buckle 2 are same
Side setting, ring flange 5 are welded with left water fender coaming plate 1-1 and left water fender buckle 2 respectively.The right both ends water fender coaming plate 1-2
Side is equipped with the ring flange 5 of rectangle, ring flange 5 and the ipsilateral setting of right water fender buckle 3, and ring flange 5 is enclosed with right water fender respectively
Plate 1-2 and right left water fender buckle 3 weld.Left water fender coaming plate 1-1 and right water fender coaming plate 1-2 passes through ring flange 5 and bolt
