Plane gate system

Abstract

The invention discloses a plane gate system, and belongs to the field of water conservancy and hydropower engineering. The plane gate system is used for solving the problem that a gate leaf of an accident gate or an overhaul gate needs to be disassembled and lifted out from a gate groove and then overhauled. The plane gate system comprises a main gate and a horizontal gate; the main gate comprises a main gate groove and a main gate leaf, and the main gate leaf can move in the main gate groove; the horizontal gate comprises a horizontal gate groove and a horizontal gate leaf, and the horizontal gate leaf can move in the horizontal gate groove; and the horizontal gate groove and the main gate groove are formed in a crossed communicating mode, and the horizontal gate leaf can extend into the middle of the main gate groove to partition the main gate groove. The main gate groove can be partitioned through the horizontal gate, the situation that the main gate leaf is disassembled and then lifted out from the gate groove is not needed, and even on-site on-line overhauling can be conducted without disassembling the main gate leaf; and the gate leaf of the horizontal gate can also be subjected to on-site on-line overhauling after the main gate leaf is subjected to gate closing.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering, in particular to a planar gate system. Background technique [0002] In domestic water conservancy and hydropower projects, it is stipulated that emergency gates should be set on the upstream side of the working gates of submerged hole discharge channels. For gates with high water head and long discharge channels, the necessity of setting up maintenance gates in front of emergency gates should also be studied. The emergency gates or maintenance gates are usually plane gates. The door leaves of the emergency gates or maintenance gates need to be disassembled and lifted out of the door slots for maintenance. Therefore, most of the emergency gates or maintenance gates installed upstream of the working gates are made of The vertical shaft or shore tower structure reaches above the water surface to meet the needs of maintenance after the door leaf is raised, and there is a ...

Problems solved by technology

The emergency gates or maintenance gates are usually plane gates. The door leaves of the emergency gates or maintenance gates need to be disassembled and lifted out of the door slots for maintenance. Therefore, most of the emergency gates or maintenance gates installed upstream of the working gates are made of The vertical shaft or shore tower structure reaches above the water surface to meet the needs of maintenance after the door leaf is raised, and there is a situation of large civil construction investment

as attached image 3 As shown in the structure diagram of the conventional shaft gate, the top of the plane gate shaft needs to be set above the water retaining liquid level, so as to facilitate the dismantling and lifting of the gate for maintenance, and for the installation of hoist parts, etc., resulting in corresponding The amount of concrete work that needs to be built is large; and the high shaft is prone to the risk of shaft deformation due to unstable geological conditions
