Description
Technical Field
The utility model relates to a gate water seal structure, especially a U-shaped combination water seal structure that is used for rotatory gate of multisection bottom shaft.
Background
The bottom shaft rotary gate is a novel gate form which is gradually developed in China in recent years, combines the characteristics of the traditional steel gate and the rubber dam and the actual needs of hydraulic engineering in China, and is suitable for urban river water environment treatment engineering. The gate is usually composed of a plurality of sections of gates with independent supports, and the main bearing parts of the gates are a whole bottom shaft or a plurality of bottom hinge devices. The gate sections adopt intersegmental water seal, and a single gate can be freely opened and lifted and can connect a gate system into a whole, so that the water leakage between the sections is ensured; the bottom panel of the gate is connected with a bottom water seal fixed on the gate bottom plate, and the side surface internode water seal is also glued with the bottom water seal to ensure that the bottom does not leak water.
Usually, the internode water seal adopts a prepressing method to tightly press the two opposite internode water seals together, so as to ensure that the water does not leak. Internodal water seals often employ a "straight", "L" or "P" cross-section. Because the span is larger, the opening of each section of gate is different to some extent in the opening process, the line distance reflected on the top of the gate leaf is larger, and water leakage is easy. The panel at the bottom shaft of the gate is often made into a cambered surface structure, and the joint of the internode water seal root and the bottom water seal is easy to leak water.
Under the above circumstances, the water leakage of the water seal is not favorable for the normal operation of the rotary gate of the bottom shaft, and the water leakage of the water seal seriously affects the water retaining effect of the whole project.
Under the general condition, the rotary gate of the bottom shaft allows the two adjacent gate leaves to be asynchronous within a certain range in the lifting and lodging processes, the device to be detected detects and feeds back data to the hydraulic opening and closing system, and the deviation rectification adjustment is carried out through closed-loop control, so that the asynchronous phenomenon is continuously reduced. But the river course is wider usually in the engineering, and the great corner of must having when single-leaf gate span is great is asynchronous for the deformation that reflects at the gate top is great, under the untimely condition of rectifying, makes the asynchronous error of door leaf bigger and bigger. If the internode water seal with the straight section is adopted, the water seal faces the threat of being torn; if the gate is of an L-shaped or P-shaped section, the gate needs to be processed into a left-right asymmetric structure to meet the working condition that water does not leak between the sections, which brings great trouble to the design and manufacture of the gate.
