Automatic switch of pocket floor moraine discharging gate

Abstract

The invention discloses an automatic switch of a pocket floor moraine discharging gate. The automatic switch of the pocket floor moraine discharging gate comprises a main gate body on the gate wall and a pocket floor, a control mechanism on a gate wall dam face, a switching door and a supporting point, wherein the switching door and the supporting point are arranged on the rear side of the main gate body, and a moraine discharging door is arranged at the bottom of the main gate body. The automatic switch is characterized in that a gate chamber doorsill is a cross beam, the surface, connected with the left-falling stroke of the Chinese character 'ren', of the cross beam is a main gate body diagonal upstream, and the surface, connected with the right-falling stroke of Chinese character 'ren', of the cross beam is a switching door diagonal downstream; the control mechanism comprises a cylindrical sleeve shaft, a brake switch, a contracting steel cable, a turning point, a steel cable non-return device and a linkage wheel for contracting of the steel cable; a door body works through rotation of the cylindrical sleeve shaft, the two ends of the shaft are fixed to the gate walls on two sides, and guide water flow on the pocket floor flushes moraine in a buffering mode. The automatic switch of the pocket floor moraine discharging gate has the advantages of being simple in structure, safe, firm and the like.

Description

technical field [0001] The invention relates to the technical field of water conservancy facilities, and more specifically relates to an automatic switch for a moraine-discharging gate at the bottom of the gate. Background technique [0002] The bottom sill of traditional dam gates is too high, and there is no moraine drainage groove at the bottom. For example, the water level of Sanmenxia on the Yellow River is several hundred meters high. In order to solve the threat of sediment to the lives and property of millions of people in the upstream Weihe River, Xiaolangdi Reservoir was attached. However, it failed to do so. The Minister of Water Conservancy instructed to lower the energy storage of Sanmenxia by 2 meters, which is still a national concern. A moraine gate was installed at the bottom of the sluice. Refer to figure 1 The dam of Tanshan Hydropower Station in Ningxiang, Changsha City, Hunan Province is 4 meters high, and the flap gate is 3 meters high. Considering that...

Problems solved by technology

However, it failed to do so. The Minister of Water Conservancy instructed to lower the energy storage of Sanmenxia by 2 meters, which is still a national concern. A moraine gate was installed at the bottom of the sluice. Refer to figure 1 The dam of Tanshan Hydropower Station in Ningxiang, Changsha City, Hunan Province is 4 meters high, and the flap gate is 3 meters high. Considering that the sediment immersion in the reservoir area will endanger the safety of the sluice chamber and the upstream, the moraine discharge gates with screw actuated switches are designed on both sides. The distorted flow direction of the river is not correct, and the effect of removing sediment is not good
