Hydraulic power self-lifting anti-flood wall

Abstract

The invention discloses a hydraulic power self-lifting anti-flood wall. The hydraulic power self-lifting anti-flood wall is formed by sequential overlapped installation of a base layer, a lifting bottom layer and a lifting top layer under the cooperation of a sliding groove structure and a limiting structure. A supporting pillar I and a supporting pillar II are sequentially installed at the bottomend of the lifting bottom layer. A supporting triggering device and an air hole automatic adjusting device are installed in the lifting bottom layer. A reset spring bolt in the supporting triggeringdevice is connected with a position fixing support, a reset spring and a linking shaft, and the linking shaft penetrates a spring limiting beam to be connected with a rigid closed supporting structureII. The spring limiting beam is connected with the bottom end of the supporting pillar II through a spring. The hydraulic power self-lifting anti-flood wall is simple in structure, operation runningunder flood conditions is stable and reliable, the anti-flood height and the flow capability are improved, the anti-flood labor is greatly saved, and the peak shifting and preparing time is further provided for downstream flood fighting and emergency rescuing.

Description

technical field [0001] The invention belongs to the technical field of flood control, and in particular relates to a hydraulic self-lifting flood wall. Background technique [0002] Natural floods caused by floods have always been one of the main natural disasters in our country, causing immeasurable losses to economic and social development. Due to the complexity of factors affecting floods and the limitations of human understanding of the natural world, the exact time, location, scale and process of floods cannot be predicted at present. The impact of flood disasters cannot be avoided, and the design of embankment buildings is particularly important in reducing flood losses. [0003] The main variable load in the structural design and reliability analysis of embankment buildings is water pressure, and the water pressure is closely related to the fortification flood level of local buildings. At present, the determination of the fortification flood level of embankments is ...

AI Technical Summary

Problems solved by technology

This utility model has the following defects: during operation, live working equipment such as sensors are easily damaged under extreme flood conditions, and the probability of equipment function loss increases, reducing its overall reliability, and the losses caused to it will be incalculable ; In addition, sensors, hydraulic cylinders and other equipment need regular maintenance, which in disguise increases flood control costs and manpower input
