This application is through the improvement to current stagnant water mechanism, installs the one deck corrosion resistant plate outside the lower extreme, and stagnant water rubber is direct to contact with the corrosion resistant plate, compares in having better laminating nature with lower extreme direct contact, and sealed effectual can not have the influence to the stagnant water effect in the short term, long-term use can avoid the risk of leaking again, and with the coefficient of friction between the stagnant water rubber less, more can play the effect of protection stagnant water rubber, extension its life.
Description
Technical Field
The utility model relates to the technical field of water conservancy electromechanical gate devices, in particular to a steel dam gate page bottom shaft water stop mechanism.
Background
A bus pivot gate with flood discharging function in water conservancy and hydropower engineering belongs to a particularly important load in primary loads. The gate can be used for intercepting water flow, controlling water level, regulating flow, discharging sediment, floating objects and the like, the steel dam in the prior art comprises a gate page and a bottom shaft, and the flap gate driven by the bottom shaft is one of gate gates of the steel dam in water conservancy construction, and has been increasingly applied due to good landscape effect.
Most of traditional bottom shaft middle bearing seats are integral bearing seats, the bottom shaft drives the door leaf to open or close, and the door leaf does not block water when lying horizontally, so that ships can pass conveniently; the full water head water retaining when the door leaf is plumbed can bidirectionally retain water, regulate and control water flow. Because the water stop needs to rotate on the bearing seat along with the door leaf when the door leaf is opened and closed, the rubber is easy to wear due to the pre-pressed friction force, and meanwhile, the defect of easy water leakage exists between the door leaf and the bearing seat.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides a novel steel dam door leaf bottom shaft water stopping mechanism, which can prolong the service life of a water stopping rubber and ensure the water stopping effect.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
the bottom shaft water stopping mechanism of the steel dam door leaf comprises a door leaf, a bottom shaft and a water stopping structure, wherein the bottom shaft is positioned at the bottom of the door leaf, the bottom shaft drives the door leaf to rotate within the range of 0-90 degrees through a transmission mechanism connected to two ends or one end, and a water stopping arc plate is additionally arranged on one side of the bottom shaft, which does not rotate; the water stop structure comprises a water stop seat, a water stop rubber and a water stop pressing plate which are sequentially connected, and the water stop rubber is propped against the water stop arc plate.
Further, the water stop arc plate is made of stainless steel, and the radian of the water stop arc plate is 105 degrees.
Further, the bottom shaft is fixed on the concrete foundation through the hinged support, and one end of the water stop seat is fixed on the concrete foundation in a sealing mode.
The beneficial effects of the utility model are as follows: the steel dam door leaf back shaft sealing mechanism that the present provided through the improvement to current sealing mechanism, installs the one deck corrosion resistant plate outside the back shaft, and the radian of steel sheet is 105 give back shaft activity space, and the sealing rubber is direct to contact with the corrosion resistant plate, compares in having better laminating nature with back shaft direct contact, and sealed effectual can not have the influence to the sealing effect in the short term, and long-term use can avoid the risk of leaking again, and is littleer with the coefficient of friction between the sealing rubber, more can play the effect of protection sealing rubber, prolongs its life.
Drawings
Fig. 1 is a schematic perspective view of a steel dam door leaf bottom shaft water stop mechanism according to the present utility model.
Fig. 2 is a side view partially enlarged view of a steel dam door leaf bottom shaft water stop mechanism.
Detailed Description
The present utility model is described in further detail below with reference to examples to enable those skilled in the art to practice the same by referring to the description.
Examples: the scheme provides a steel dam door leaf bottom shaft water stopping mechanism shown in the figures 1-2, which comprises a door leaf 1, a bottom shaft 2 and a water stopping structure 3, wherein the bottom shaft 2 drives the door leaf 1 to rotate within the range of 0-90 degrees through a transmission mechanism 4 connected to two ends or one end, and a water stopping arc plate 5 is additionally arranged on one side of the bottom shaft 2, which does not rotate; the water stop structure 3 comprises a water stop seat 31, a water stop rubber 32 and a water stop pressing plate 33 which are sequentially connected, and the water stop rubber 32 is propped against the water stop arc plate 5.
In the above embodiment, the water stop arc plate 5 is made of stainless steel, and the arc is 105 °. The water stop rubber 32 moves in the arc angle, the water stop rubber 32 is in direct contact with the stainless steel plate, has better laminating property compared with the direct contact with the bottom shaft 2, has good sealing effect, can not influence the water stop effect in a short period, can avoid the risk of water leakage after long-term use, has smaller friction coefficient with the water stop rubber, can play a role in protecting the water stop rubber, and prolongs the service life of the water stop rubber.
Further, the bottom shaft 2 is fixed on the concrete foundation through the hinged support 6, and one end of the water stop seat 31 is fixed on the concrete foundation in a sealing manner. The water stop seat 31, the water stop rubber 32 and the water stop pressing plate 33 are connected through bolts and nuts, and after the water stop seat 31 is fixed, the whole water stop structure 3 is kept fixed.
Although embodiments of the present utility model have been disclosed above, it is not limited to the use of the description and embodiments, it is well suited to various fields of use for the utility model, and further modifications may be readily apparent to those skilled in the art, and accordingly, the utility model is not limited to the particular details without departing from the general concepts defined in the claims and the equivalents thereof.
