Abstract

The invention relates to the technical field of salt suppression in river channels, and discloses a latent salt suppression movable flapper structure, which includes a frame body fixed in the river channel and vertically arranged upward along the river channel. The high tide side and the low tide side towards the ebb direction; the high tide side of the frame body is provided with a flexible shielding film, the upper end of the flexible shielding film is connected with the top edge of the frame body, and the lower end of the flexible shielding film is movable; there are many connections on the flexible shielding film a horizontal strip, the horizontal strip is arranged along the width direction of the flexible shielding film, and a plurality of transverse strips are arranged at intervals along the height direction of the flexible shielding film; by setting a frame body at the bottom of the river channel, the frame body is provided with a flexible shielding film, When the tide is high, the flexible shielding membrane is pressed against the frame body, blocking the upward movement of the salt water wedge at the bottom of the river, weakening the upward strength of the salty tide. cause obstruction.

Description

technical field [0001] The patent of the present invention relates to the technical field of salt suppression in river channels, in particular, it relates to a latent salt suppression movable valve structure. Background technique [0002] The estuary area is an area where salt and fresh water are mixed, and the radial and tidal forces meet. Due to the difference in density, the water flow has obvious stratification phenomenon. The high tide goes up along the bottom, and its interface inclines upstream in a wedge shape, so it is called a saltwater wedge. Due to the intrusion of the salt water wedge, super-standard salt water appeared at the intake of the water plant in the upper reaches of the river, making it impossible for the water plant to obtain fresh water, which affected the safety of the city's water supply. [0003] In the past 10 years, salt tide activities in the Pearl River estuary have become more frequent, the scope of influence has become larger and longer, an...
