Abstract
The utility model relates to a lintel water-stopping structure of an arc-shaped sluice gate, which belongs to the metal structure parts in water resources and hydropower engineering. A down-the-hole lintel water-stopping structure of an arc-shaped sluice gate is comparative complicated. To solve the problems that the second water-stopping structure of the existing lintel water-stopping structure of arc-shaped sluice gate can be easily torn up and has high requirements of manufacture and installation accuracy, the utility model provides a lintel water-stopping structure of an arc-shaped sluice gate, which has a novel structure and a reasonable and feasible design. In the structure, a set-up spring which can move along a guide post is additionally arranged on a movable hinge plate. When a supporting leg of an arc-shaped sluice gate is compressed and deformed in an application process, under the action of a compression spring and water pressure, a water-stopping rubber and a sluice gate panel are kept into a favorable water-sealing effect all the time.
Description
The utility model belongs to Hydraulic and Hydro-Power Engineering metal construction part.Segment gate is used for water conservancy and hydropower multi-purpose project envelope, stifled intake-outlet.
The top sealing of submergence type Segment gate mostly is located at the upstream of cambered surface, and establishes twice lintel water-stopping structure, and its form is more, but all is gate flap one, and the gate slot built-in fitting together.It is to utilize to conduct oneself with dignity by gate at closing time to compress the top sealing and leakproof that one sealing wherein arranged.This water-stopping structure is fairly simple, elevation is installed to reach all requirements of the tight sealing of energy of top sealing and end water but be difficult for regulating it, and it is higher to make installation accuracy, and in recent years, everyway is being tried to explore new sealing form.
Task of the present utility model provides a kind of, by the precompression of bolt regulating spring, places the twice water stop rubber on the same movable pivoted arm to make water stop rubber be close to the gate panel in the effect of spring and water pressure, thereby reaches satisfied stagnant water effect.
Its solution is: pre-buried one fixing hinge plate on gate slot, and it is linked to each other with its moveable hinge plate by hinge, adjust bolt in addition between two hinge plates, pre-compressed spring connects rubber tile.Fixing twice water stop rubber on the moveable hinge plate, first road is " Ω " type rubber, second road is " P " type rubber.
So where necessary, can adjust the compression spring, its twice rubber is contacted well with the Segment gate panel outer surface by bolt.Under the situation of less head, also can guarantee stagnant water effect.Advantage of the present utility model also has: water stop rubber has certain floatability on the basis of pre compressed magnitude 2-3mm, gate water stop rubber abrasion in opening-closing process is relatively alleviated to some extent.Compliance to the alignment error of the compressive strain of Segment gate support arm and lintel embedded part and door body is also better.
Further improvement of the utility model is to establish the compression spring and can under spring and effect of water pressure, make water stop rubber and panel that excellent contact be arranged along the direction activity of lead between fixing hinge plate and moveable hinge plate.
Accompanying drawing has been described an embodiment of the present utility model.
The section at Fig. 1 Segment gate axial location place, expression panel, the contact form between water stop rubber.
1. Fig. 1 represents the Segment gate panel, " P " type rubber 2., 1. " Ω " type rubber 3. by contacting with Segment gate gate flap panel, reach stagnant water effect, the moveable hinge plate 5. can be by adjusting the angle that 5. nut fine setting moveable hinge plate tilts, make water stop rubber reach itself and panel 1. between suitable precompression.Stage clip is 10. along being welded on the 9. activity of lead that 6. fixing hinge plate is gone up.8. 5. 6. fixing hinge plate be connected by hinge with the moveable hinge plate, and 8. 5. the moveable hinge plate can rotate around hinge.4. dull and stereotyped rubber is connected and fixed the hinge plate 6. on the structure by securing member, the moveable hinge plate 5., 7. 6. fixing hinge plate be embedded in the gate slot second phase concrete by crab-bolt.
Claims (2)
1, in hydraulic engineering, a kind of Segment gate lintel water-stopping structure, under the effect of spring and water pressure, rotation along with the moveable hinge plate, make water stop rubber and Segment gate panel keep excellent contact, it is characterized in that: " P " type rubber 2., " Ω " type rubber is 3. with placing the moveable hinge plate 5. to go up, 6. 8. 5. the moveable hinge plate link to each other with fixing hinge plate by hinge.
2, Segment gate lintel water-stopping structure according to claim 1 is characterized in that: 9. the screwed lead of an end is welded on fixing hinge plate and 6. goes up, and 9. 10. the compression spring is inserted in lead goes up, and 9. lead adjusts nut (11) on the end of thread band.
