Operation device and method capable of quickly locking flood gate of large hydropower station

Abstract

The invention provides an operation device and method capable of quickly locking a flood gate of a large hydropower station. The operation device comprises a base, a transmission rack is slidably mounted in a cavity of the base along the length direction of the base, and the transmission rack is connected with a power device for driving the transmission rack to move transversely; the transmission rack is in meshing transmission with a plurality of driven gears at the same time; the driven gears are supported between the bases through a gear shaft; each driven gear is in meshing transmission with two vertical spring bolt rods which are oppositely and symmetrically arranged at the same time; a sliding guide structure for limiting the vertical spring bolt rod is arranged on the outer side of the vertical spring bolt rod, and the vertical spring bolt rod can only slide in the vertical direction; and transverse spring bolt rods are fixed to the outer side walls of the two vertical spring bolt rods located on the outermost side. According to the operation device, the closed flood gate can be quickly and firmly connected with a basic component, so that the flood gate can be quickly put into an operation working condition.

Description

technical field [0001] The invention belongs to the technical field of hydraulic metal structures of hydropower stations, in particular to an operating device for quickly locking flood control gates of large hydropower stations, which can be widely used in other engineering fields requiring frequent opening and closing of flood control gates. Background technique [0002] For hydropower stations designed and arranged in the form of underground powerhouse structures, various types of traffic tunnels, grouting corridors and drainage corridors are generally provided. One end of these traffic tunnels and corridors is close to the upstream, downstream or riverside, and the other end is Connected to the factory building. According to the operation mode of the hydropower station, the whole year is divided into flood season and non-flood season. During the flood season, due to the large amount of rain, the large amount of seepage from the mountain and the rapid rise and change of th...

AI Technical Summary

Problems solved by technology

[0003] At present, hydropower stations in the form of underground powerhouses are equipped with flood gates of various structures to prevent large floods from submerging the powerhouses. However, there are generally two ways to lock them after they are closed. One is to use bolt connection, that is, flood gates After closing, the flood gate is connected to the foundation with bolts. Although this method can effectively connect the flood gate firmly, it is a waste of manpower and material resources in the field operation process. Every time the gate is opened and closed, it needs to be replaced. The bolts and tools are transported to the site. First, the gate is tightened in place by the manual hoist, and then the bolts are installed and tightened one by one. In case of sudden flood, the flood gate cannot be closed quickly, and the meaning of setting up the flood gate is lost. The second is to connect the flood gate with the hook, that is, connect the flood gate to the basic components through the hook. Although this method can realize fast closing, it cannot effectively and firmly connect the flood gate, which will lead to insufficient water seal compression of the flood gate. Water leakage occurs, and the real flood control effect cannot be achieved
