Automatic switch of rotary type plane gate

Abstract

The invention discloses an automatic switch of a rotary type plane gate. The automatic switch of the rotary type plane gate comprises a control mechanism of an upper dam lock chamber and a plane gate arranged in a dam and located close to a water source. The automatic switch of the rotary type plane gate is characterized by further comprising an assisting door and a water diversion stop plate which are arranged on the dam side, wherein a movable shaft is arranged in the middle of the plane gate, the control mechanism comprises a shrinkage steel rope, a fixed pulley and a linkage wheel, and the shrinkage steel rope surrounds the linkage wheel and the fixed pulley and is connected with one end of the assisting door and the plane gate. The assisting door is arranged on the side portion of the dam through the movable shaft. The water diversion stop plate is arranged outside the plane gate and is close to the assisting door. The portion, allowing the assisting door to be attached to, of the dam is provided with a hidden portion corresponding to the shape of the appearance of the assisting door. The automatic switch of the rotary type plane gate has the advantages of being simple in structure, low in construction cost, practical and the like.

Description

technical field [0001] The invention relates to the technical field of water conservancy equipment, and more specifically relates to an automatic switch of a rotary plane gate. Background technique [0002] At present, the plane gate in hydraulic technology has a long history and a relatively simple structure. Large-scale Tuochi power station, six-hole water diversion for power generation, and nine-hole flood discharge all use plane gates, 9 meters high and 14 meters wide. For example, the Tanshan Barrage Power Station in Ningxiang, Hunan has installed hydraulic impact flap gates. The whole line consists of dozens of holes and three-meter-high plane gates to automatically switch and discharge floods. The frictional force is very different, and it is necessary to set up gate slots, super-high dam surface hoists and thick gate piers, and large plane gates are opened and closed by power source high-altitude operation, and the construction cost is high. The defect of the hydra...

Problems solved by technology

For example, the Tanshan Barrage Power Station in Ningxiang, Hunan has installed hydraulic impact flap gates. The whole line is composed of dozens of holes and three-meter-high plane gates to automatically switch and discharge floods. The defect is that the traditional plane gates are affected by the water head. The frictional force is very different, and it is necessary to set up gate slots, super high dam surface hoists and thicker gate piers, and large plane gates are opened and closed by high-altitude operation powered by power supply, and the construction cost is high.

The defect of the hydraulic impact flap gate is that during the flood discharge, the gate, the legs, the fixed arc-shaped teeth of the buttress, and the curved and straight supports lie in the flood against the current and are easily washed away by the flood. It was rebuilt here. It is inevitable that sundries will block the outriggers due to flooding, and the outriggers cannot be reset. Manual power operation is often used to reset, which is time-consuming and laborious.
