Abstract
The utility model discloses a fixed wheel anti-seepage device for a downstream water stop plane surface fixed wheel strobe. The fixed wheel anti-seepage device comprises fixed wheels arranged between a boundary beam inner side web board and a boundary beam outer side web board; circular sleeves are welded in a sealing manner on the side board surface downstream the inner side web board surrounding the shaft end parts of the fixed wheels; the sleeve opening of each circular sleeve adopts a flanging structure extending outwards in the radial direction; the sleeve opening of each circular sleeve is sealed with a pressing plate through a rubber sealing ring. The fixed wheel anti-seepage device provided by the utility model has the following advantages: a sealed cavity is formed by the circular sleeves and the pressing plate is arranged on the side board surface downstream the inner side web board surrounding the shaft end parts of the fixed wheels. Therefore, water flow can only seep into the sealed cavity from a fixed wheel shaft hole, and the water flow is effectively prevented from seeping the lower reaches; particularly, for the plane surface fixed wheel strobe with a high water head, possible phenomenon of jet flow is effectively prevented, so that possible potential safety hazards of the plane surface fixed wheel strobe are avoided.
Description
Technical field
The utility model relates to the type flat of hydraulic engineering middle and lower reaches sealing, especially relates to the fixed wheel percolator for downstream sealing type flat.
Background technology
In hydraulic engineering, adopt the type flat of downstream sealing, because sealing is arranged in downstream, gate fixed wheel is arranged in gate slot inner side, current enter in side bar through fixed wheel installing hole by side bar bottom flange, owing to being matched in clearance between fixed wheel axle and gripper shoe, current will ooze downstream by fixed wheel axis hole, for the type flat using under high water head operating mode, may there is jet in fixed wheel axis hole, gate safe operation is produced to hidden danger.
Summary of the invention
The utility model object is to provide a kind of fixed wheel percolator for downstream sealing type flat.
For achieving the above object, the utility model is taked following technical proposals:
Fixed wheel percolator for downstream sealing type flat described in the utility model, comprise the fixed wheel being arranged between the web of side bar medial and lateral, be positioned in the lateral plates of described endosternum downstream and have ring set around the wheel shaft Seal welds for ends of described fixed wheel, the running-on of described ring set is the turnup structure extending radially outward; The running-on of described ring set is by rubber seal ring and pressing plate for sealing.
The utility model advantage is just to be provided with around the fixed wheel shaft end in the lateral plates of described endosternum downstream the closed cavity being made up of ring set, pressing plate, like this, current can only penetrate in this closed cavity from fixed wheel axis hole, thereby effectively stop the seepage in current direction downstream, particularly for high water head type flat, reach and effectively prevent contingent jet phenomenon, thereby avoided the issuable potential safety hazard of type flat.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, fixed wheel percolator for downstream sealing type flat described in the utility model, comprise the fixed wheel 3 between the side bar medial and lateral web 1,2 being arranged in gate gate slot 8, be positioned in described endosternum 1 downstream lateral plates and have ring set 5 around wheel shaft 4 Seal welds for ends of described fixed wheel 3, the running-on of described ring set 5 is the turnup structure extending radially outward; The running-on of described ring set 5 seals by rubber seal ring 6 and pressing plate 7; Interval 5mm to 10mm between the end of wheel shaft 4 and described pressing plate 7, to avoid the interference of pressing plate 7 to wheel shaft 4.
Claims (1)
1. the fixed wheel percolator for downstream sealing type flat, comprise the fixed wheel (3) being arranged between side bar medial and lateral web (1,2), it is characterized in that: being positioned at wheel shaft (4) Seal welds for ends around described fixed wheel (3) in the lateral plates of described endosternum (1) downstream has ring set (5), and the running-on of described ring set (5) is the turnup structure extending radially outward; The running-on of described ring set (5) is by rubber seal ring (6) and pressing plate (7) sealing.
