example 1
As shown in fig. 3-5, the moving column 4 is further provided with a back plate 45, and the upstream surface compressing device is an upstream surface compressing bolt 4012 arranged on the back plate 45. The upstream surface compressing device acts, namely screws in the upstream surface compressing bolt, and drives the panel to approach and prop up the flood prevention baffle.
Example two
As shown in fig. 6-8, the upstream surface compressing device is an eccentric shaft mechanism arranged between the top plate 43 and the bottom plate 44, and the eccentric shaft mechanism is positioned at the inner side of the flood control baffle 2. The eccentric shaft mechanism comprises a shaft body, shaft heads and a rotary handle, wherein the shaft heads are respectively arranged at two ends of the shaft body and eccentrically arranged, the rotary handle is arranged on the shaft heads positioned at the upper parts of the shaft bodies, and is used for holding and realizing the rotation of the shaft heads so as to drive the shaft bodies to rotate.
A bottom sealing strip 31 is arranged on the bottom edge of the flood prevention baffle 2. The combination between the bottom edge of the flood prevention baffle and the ground is more compact, and the sealing reliability of the bottom surface is ensured.
A side seal 32 is provided on the surface of the inner edge 11 of the door or on the outer surface of the side plate 41 of the movable column 4. The combination between the outer surface of the movable column and the inner edge of the door is more tight, and the reliability of side sealing is ensured.
The inner surface of the panel 42 of the movable column 4 or the outer surfaces of the two ends of the flood control baffle 2 are provided with water facing surface sealing strips 33. The combination between the movable column panel and the flood prevention baffle is more compact, and the reliability of water surface sealing is ensured.
In operation, the double-headed nut 25 rotates to drive the ejector rods 22 at the two ends to stretch outwards, so that the movable column 4 moves to two sides until abutting against the inner edge 11 of the door, and the side sealing is realized by combining the side sealing strips 32 arranged on the outer surface of the inner edge 11 of the door or the side plate 41 of the movable column 4.
The top pressing device arranged on the top plate 43, such as the top pressing bolt 4011, tightly presses the flood control baffle 2 arranged between the top plate 43 and the bottom plate 44 of the movable column 4 when being screwed in, and combines with the bottom sealing strip 31 (which can be arranged on the bottom edge of the flood control baffle 2) to realize bottom sealing. Of course, the top hold-down device may also employ an eccentric mechanism (not shown; this hold-down mechanism can be implemented directly without any creative effort by a person skilled in the art from the above description).
The sealing of the upstream surface provides two embodiments, the first embodiment is the structure form of the upstream surface compression bolt 4012 as shown in fig. 3-5, but when adopting this embodiment, the movable column 4 needs to be additionally provided with a back plate 45.
The second embodiment is an eccentric shaft mechanism as shown in fig. 6-8, and when the rotary handle is turned, the shaft body 40211 rotates to drive the flood control barrier 2 to move outward in the Z direction until the panel 42 of the moving column 4 is abutted. In the two embodiments, the upstream face sealing is realized by combining the upstream face sealing strips 33 arranged on the upstream face of the two side ends of the flood control baffle 2 or the back face of the panel 42.
By the side seal, the bottom seal and the upstream surface seal, waterproof and flood control can be reliably realized, and the sealing device is simple to operate, convenient to assemble and disassemble and high in sealing reliability.
