Hydraulically automatic lifting flood prevention walls and automatic lifting method

Abstract

The invention relates to a hydraulic automatic lifting flood control wall, which is arranged side by side along the inner side of a river embankment, and includes a driving device, a locking mechanism, a column, a base, and a baffle. The side of the column is provided with a chute corresponding to the baffle; the inner cavity of the base is provided with a driving device corresponding to the baffle, and the driving device includes a water wheel and a pulley block, and the water wheel drives the baffle to move up and down along the chute through the pulley block ;A liftable baffle is set up. The baffle is hidden in the base of the flood control wall during non-flood season. When the flood arrives and reaches a certain water level, the flood control baffle will automatically rise under the action of the traction force of the waterwheel. After the baffle rises to the upper part of the column, The bayonet on the top of the baffle is docked with the locking mechanism on the column to form a fixed connection relationship, and the baffle is used to block the flood and complete the flood control task.

Description

technical field [0001] The invention belongs to the field of urban flood control, and in particular relates to an automatic lifting flood control wall that takes into account both urban flood control and urban landscape. Background technique [0002] At present, river embankments in cities are effective channels to avoid flood disasters, and can release floods in summer, effectively protecting the safety of cities in the river basin. In order to control the destructive effect of the peak water flow of the river on the hinterland of the river channel, parallel flood embankments or flood walls are often built along both sides of the river channel to avoid possible damage caused by floods, such as floods that will cause changes in the ecological environment in the watershed, It causes changes in the river course, soil erosion and barren land, etc., and even washes away and destroys the vegetation and buildings on the river bank, which poses a huge threat to people. Therefore, ...

AI Technical Summary

Problems solved by technology

However, the application of these new technologies and concepts has not fundamentally changed the barrier characteristics of the dam; nor has it truly released the landscape value of the river water surface in its urban hinterland development zone

Generally speaking, the elevation of the top of the embankment will be at least 4 meters higher than that of the development plot, and the first or even second floors of the buildings adjacent to the river bank cannot see the water surface at all, but "nest" in the shadow of the river bottom; at the same time, The bottom two floors of the building are probably used for commercial development, which greatly reduces the value and charm of waterfront buildings

Moreover, it is not easy to form a high-energy, high-value waterfront space to accommodate public activities
