Technical Field

The invention relates to the technical field of sluice water seal systems, in particular to a telescopic sluice water seal system.

Background

Along with the gradual increase of high-head hydroelectric engineering construction projects in China, the water pressure borne by the gate is increased, and the requirement on the water sealing capability of the water seal is increased correspondingly. The water seals applied to the current high water head gate are roughly three types: the water seal comprises a conventional water seal, a telescopic water seal and an eccentric hinged water seal, wherein the telescopic water seal is formed by applying back pressure on the back surface of the water seal and pushing the head of the water seal to extend outwards to extrude a gate panel so as to achieve the purpose of water stopping. Because of good water stopping effect and simple manufacturing process, the telescopic water seal is more generally applied to a high-head gate.

Firstly, considering that the difference between water levels upstream and downstream is large during flood discharge, the constraint between the gate and the gate slot only depends on the friction action of a contact surface, and the gate has the possibility of integral instability when being subjected to large water pressure; secondly, because the speed of overflowing water between the gap between the gate and the gate slot is large when the gate is opened and closed, the opening and closing of the telescopic water seal are not facilitated, and the telescopic water seal is easily damaged to a certain extent.

Disclosure of Invention

The invention aims to solve the existing problems and provide a telescopic sluice water seal system which can not only enhance the integral stability of a high-head lower gate, reduce the vibration generated under the action of water load, but also weaken the flow speed of water flowing between the gate and a gate groove.

the front side and the rear side of the gate are respectively provided with a water-facing panel and a backwater panel, two ends of the water-facing panel extend to form first bulges, the side surface of each first bulge is provided with a first energy dissipation block, and two ends of the backwater panel extend to form second bulges;

the gate slot is arranged on the left side and the right side of the gate, a mortise is formed between the gate slot and the gate, a second energy dissipation block is arranged on the side surface of the gate slot, and the second energy dissipation block corresponds to the front and back positions of the first energy dissipation block; and

the first water seal is arranged in the mortise and used for sealing and sealing water.

The invention has the beneficial effects that: the gate is of an I-shaped structure, the displacement of the gate along the water flow direction is restrained in a certain range, the anti-overturning capacity of the gate under a high water head is enhanced, the overflowing water speed between the mortise is weakened by the energy dissipation block, the stress condition at the water seal part of the gate is improved, the opening and closing of the telescopic water seal are facilitated, and the service life of the water seal of the gate is prolonged; in addition, the energy dissipation block enhances the anti-cutting capability of the water-facing panel under the impact of water flow, improves the stress performance of the water-facing panel and prolongs the service life of the sluice.
