Description
Technical Field
The utility model relates to a seal structure field of gate.
Background
A culvert gate is one of important gates of hydraulic engineering, and is generally characterized in that a gate seat with at least one culvert opening formed in the bottom is fixedly connected to the bottom of a reservoir, and a pair of vertical sliding chutes are arranged on one side, facing a high water level, of the culvert opening, as shown in fig. 11-12; the gate plate in the gate is connected in a sliding way in the pair of vertical chutes. In the use process, when the gate plate is lowered to the bottom, the gate plate completely blocks the culvert opening to realize gate closing; when the gate plate is lifted upwards, the lower part of the culvert opening is exposed, so that water flow can flow from the high water level side to the low water level/waterless side, and the gate is opened.
Therefore, on one hand, the good sliding connection relationship between the gate plate and the gate seat is required to be kept, so that the problems of blocking, stagnation and the like of the gate plate are avoided; on the other hand, when the gate is closed, the gate plate and the gate seat need to be sealed efficiently.
In view of the above, a proposal for arranging a sealing strip on the surface of the gate plate has been proposed, however, the traditional sealing strip (made of rubber) is easy to cause lateral (perpendicular to the central line direction of the sealing strip) deviation due to water pressure difference in the using process, as shown in fig. 9-10, so that the component for fixing the sealing strip applies a great shearing force to the sealing strip, the actual service life of the sealing strip is extremely short, frequent replacement is required, the operation difficulty is high, and the use cost of the gate is greatly increased; meanwhile, the transverse deviation of the sealing strip can easily cause a gap to be formed between the sealing strip and the gate seat, so that the sealing is ineffective.
SUMMERY OF THE UTILITY MODEL
