Specifically, in the present embodiment, the longitudinal connecting member 120 is made of a high-strength steel material.
When the high-strength steel is used, the selection of materials is wide, the situation that the materials are difficult to use due to the adoption of scarce materials does not exist, and the high-strength steel has enough bending resistance and can effectively prevent the baffle 130 from inclining to a larger extent.
Of course, in other embodiments, other materials may be used as the material for the longitudinal connecting member 120, as long as the structural strength is satisfactory.
Specifically, in this embodiment, the longitudinal connectors 120 have a pre-stress force that urges the baffles 130 to tilt toward the side near the flood barrier.
When the baffle plate 130 is used, as the acting force of flood to the baffle plate 130 is in a certain range, the magnitude of the prestress on the longitudinal connecting member 120 can be set according to the range of the acting force of the flood to the baffle plate 130, and the magnitude of the prestress of the longitudinal connecting member 120 is set as the middle value of the range of the acting force of the flood, so that the inclination of the baffle plate 130 under the acting force of the flood is effectively reduced, and the working stability of the baffle plate 130 under the acting force of the flood is improved.
