Description

Technical Field

[0001] The invention relates to the technical field of sluice water seal systems, in particular to a telescopic sluice water seal system. Background Art

[0002] With the increasing number of high-head hydropower construction projects in my country, the water pressure on the gates is getting higher and higher, and the corresponding requirements for the water seal's water-stopping ability are getting higher and higher. At present, there are roughly three types of water seals used in high-head gates: conventional water seals, telescopic water seals, and eccentric hinged water seals. Among them, the telescopic water seal refers to applying back pressure on the back of the water seal to push the water seal head outward to squeeze the gate panel to achieve the purpose of water stopping. Due to its good water-stopping effect and simple manufacturing process, the telescopic water seal is more commonly used in high-head gates.

[0003] However, the telescopic water seal has certain defects in use. First, considering the large water level difference between upstream and downstream during flood discharge, the constraint between the gate and the gate slot relies solely on the friction of the contact surface. When subjected to greater water pressure, the gate may become unstable as a whole. Secondly, due to the high flow rate between the gate and the gate slot when the gate is opened and closed, it is not conducive to the opening and closing of the telescopic water seal, and it is easy to cause certain damage to the telescopic water seal. Summary of the invention

[0004] The purpose of the present invention is to solve the existing problems and to provide a telescopic sluice water seal system which can not only enhance the overall stability of the gate under high water head and reduce the vibration generated under water load, but also weaken the water flow rate between the gate and the gate slot.

[0005] The technical solutions of the present invention are as follows:

[0006] A telescopic sluice water seal system, comprising:

[0007] The gate has a front panel and a back panel on both sides, a first protrusion extending from both ends of the front panel, a first energy dissipation block is arranged on the side of the first protrusion, and a second protrusion extending from both ends of the back panel;

[0008] A gate slot is arranged on the left and right sides of the gate, a mortise is formed between the gate slot and the gate, a second energy dissipation block is arranged on the side of the gate slot, and the second energy dissipation block corresponds to the front and rear position of the first energy dissipation block; and

[0009] The first water seal is arranged in the mortise and is used for sealing water.

[0010] The beneficial effects of the present invention are as follows: the gate has an "I"-shaped structure, which constrains the displacement of the gate along the water flow direction within a certain range, enhances the gate's anti-overturning ability under high water head, and weakens the flow rate between the mortise and mortise with the help of energy dissipation blocks, improves the stress condition at the gate water seal, is beneficial to the opening and closing of the telescopic water seal, and extends the service life of the gate water seal; in addition, the energy dissipation blocks enhance the shear resistance of the water-facing panel under the impact of water flow, improves the stress performance of the water-facing panel, and extends the service life of the sluice.

[0019] The first water seal 301 is disposed in the mortise 240 and is used for sealing water;

[0020] The first energy dissipation block 112 and the second energy dissipation block 212 weaken the flow velocity of water between the mortise and the mortise, improve the stress condition at the water seal of the gate 100, enhance the anti-shearing ability of the water-facing panel under the impact of water flow, and facilitate the opening and closing of the telescopic water seal.

[0021] Preferably, a tenon 230 is further provided in the mortise 240, and the tenon 230 is tightly matched between the first water seal 301 and the gate groove 200. The tenon and the gate mortise cooperate with each other, constraining the displacement of the gate along the water flow direction within a certain range, thereby enhancing the gate's anti-overturning ability under high water head.
