Background

The left and right leaves of the herringbone gate respectively rotate around a vertical door shaft in the side wall of the water channel, and when the water channel is closed, the herringbone gate is overlooked to form a herringbone gate. When the herringbone gate works, the two door leaves form a three-hinge arch to bear water pressure; when the water channel is opened, the two door leaves are positioned in the door niches of the side walls, do not bear water pressure and are in a non-working state. The ship lock miter gate is high in use frequency, the daily opening and closing are conducted dozens of times, water stopping at the bottom of the gate is made of rubber, and the rubber water stopping is easy to wear and age under the high-frequency use working condition and needs to be replaced frequently.

The conventional herringbone gate is very inconvenient in water stopping at the joint of the gate shaft column and the bottom of the gate by replacing special-shaped rubber, and the main reasons are as follows: the special-shaped rubber water stop is fixed at the bottom of the door shaft column supporting cushion block through bolts and is extruded on a working surface of a conventional sill as shown in figure 2. When the special-shaped rubber water stop device works, as shown in figure 1, the special-shaped rubber water stop device makes circular motion around the rotation center of the bottom pivot, the water stop surface of the conventional bottom sill matched with the special-shaped rubber water stop device is also designed to be a concentric circular ring surface with the rotation center of the bottom pivot as the circle center, and the whole process that the special-shaped rubber water stop device runs from the fully-closed X position to the fully-opened Y position of the miter gate is always in the circular ring surface of the bottom sill and is in a compressed state without replacement. When the special-shaped rubber water seal needs to be repaired and replaced, a hydraulic hoist is usually adopted to jack the whole miter gate to a certain height (usually about 500 mm) as shown in fig. 3, and an operation space for repairing and replacing the special-shaped rubber water seal is created. Corresponding safety measures are needed to be taken in the jacking process of the miter gate to ensure that the miter gate does not overturn in the jacking process, the workload of the manual machine is huge, the consumed time is long, navigation is affected, and even inconvenience is caused.

Therefore, a miter gate convenient for replacing bottom special-shaped water stop and a using method thereof are needed to be designed.
