Automatic tide receiving layered water intaking gate device of seawater artificial lake and using method of automatic tide receiving layered water intaking gate device

Abstract

The invention discloses an automatic tide receiving layered water intaking gate device of a seawater artificial lake and a using method of the automatic tide receiving layered water intaking gate device. The automatic tide receiving layered water intaking gate device of the seawater artificial lake comprises a plurality of gate units connected in sequence from top to bottom, and the gate units comprise fixed sheets, sheet-separating type gates, open sea lateral pressure sensors, open sea lateral sand content detecting instruments, lake region lateral pressure sensors, hinge rods and electric opened and closed devices; the sheet-separating type gates are hinged to the fixed sheets through the hinge rods, and opening or closing of the sheet-separating type gates is controlled by the electricopened and closed devices; and the open sea lateral pressure sensors and the open sea lateral sand content detecting instruments are arranged on the outer sides of the sheet-separating type gates, and the lake region lateral pressure sensors are arranged on the inner sides of the sheet-separating type gates. According to the automatic tide receiving layered water intaking gate device of the seawater artificial lake, layered water intaking can be carried out on open sea muddy seawater by adjusting the number of the sheet-separating type gates, so that the sand content of the sheet-separating type gates is greatly reduced, and the requirement of lake region water quality is met. According to the automatic tide receiving layered water intaking gate device of the seawater artificial lake andthe using method of the automatic tide receiving layered water intaking gate device, a water body entering the lake region can conveniently reach the test or actual requirements, and ocean developmentuse is facilitated.

Description

technical field [0001] The invention belongs to the field of eco-hydraulics, and in particular relates to an automatic tidal-receiving and layered water intake gate device for a seawater artificial lake and a use method thereof. Background technique [0002] The sea area adjacent to the Yangtze River estuary has high sediment concentration, low water transparency, and poor water quality. In recent years, with the improvement of living standards, people's landscape requirements for the water environment in coastal waters have also gradually increased. The coastal intertidal zone isolates the peripheral water body by reclamation, constructs artificial seawater lakes, and tries to obtain clear coastal waters. However, in order to prevent algal blooms, it is necessary to continuously exchange water to speed up the frequency of water exchange to promote water circulation in seawater lakes. However, in the state of high-frequency water exchange, the high-sediment-content supply ...

AI Technical Summary

Problems solved by technology

Water intake through manual operation of the gate cannot achieve real-time and accurate water intake operation, which will reduce the amount of water exchange entering the lake area

[0006] The above two points will lead to the inability to meet the full water exchange volume of the seawater artificial lake, thereby affecting the water quality of the lake area, affecting the hydrophilicity and landscape aesthetic requirements

[0007] At present, artificial seawater lakes do not have devices and equipment that can automatically control water intake through gates and can achieve stratified water intake requirements for middle and upper layers of low-sediment water layers.
