Embodiment Construction

[0020] Such as figure 1 As shown in -6, it is a foldable steel dam bottom shaft water-stop structure. The bottom shaft 3 is fixed on the bottom of the door leaf 1, and the bottom shaft 3 is fixed on the concrete foundation 4 through the hinge seat 2. The door leaf 1 and the concrete foundation 4 There is a sealing and water-stopping part 6 between them. The sealing and water-stopping part 6 includes a chain plate assembly corresponding to the two ends of the door leaf. The two chain plate assemblies are connected through a soft rubber belt 601, and the upper end of the soft rubber belt 601 is The pressing plate 604 is fixed on the door leaf 1, so that the upper end of the soft rubber belt 601 is sealed and connected with the door leaf 1. On the concrete foundation 4 and the corresponding position of the soft rubber belt is provided with a sealing embedded part 7, and the lower end of the soft rubber belt 601 passes through the lower pressing plate. 607 is fixed on the sealing ...

Abstract

The invention discloses a foldable steel dam bottom shaft watertight structure in the technical field of steel dam gates. The foldable steel dam bottom shaft watertight structure includes a bottom shaft fixed at the bottom of a gate leaf, wherein the bottom shaft is fixed on a concrete foundation through a hinged support; a water sealing element is arranged between the gate leaf and the concrete foundation; the water sealing element includes link plate assemblies corresponding to the two ends of the gate leaf; the two link plate assemblies are connected through a rubber band; the upper end of the rubber band is hermetically connected with the gate leaf, and the lower end of the rubber band is hermetically connected with the concrete foundation; the two ends of the rubber band extend out of the link plate assemblies; and each link plate assembly includes a plurality of link plates that are sequentially hinged. The rubber band can be folded and sealed at will and can be reliably supported by adopting the link plate assemblies at the two ends thereof, as a result, the two ends of the rubber band can be permanently attached onto the gate wall during the rotation of the gate leaf, and water leakage is avoided; the device is satisfactorily sealed and highly reliable to use, and has a simple structure; and the foldable steel dam bottom shaft watertight structure adopts the link plates for sealing by changing the functions of the link plates, so as to achieve an unexpected effect.

Description

technical field [0001] The invention relates to a steel dam gate device, in particular to a water stop structure of the steel dam gate. Background technique [0002] The structure of the steel dam in the prior art includes a door leaf for water retention and discharge. The bottom of the door leaf is fixed with a bottom shaft. The bottom shaft is fixed on the concrete foundation through a hinge seat. When the bottom shaft rotates, it can drive the door leaf to stand up and Lie down to realize water blocking and water release. Due to the relative movement between the bottom shaft and the concrete foundation, a water stop must be used to stop water between the two to avoid leakage. The existing water stop is fixed, one end of which is sealed and fixed on the concrete foundation, and the other One end is provided with a rubber plate that radially interferes with the side of the bottom shaft to realize dynamic sealing. Its disadvantages are: in the case of frequent opening and ...
