Problems solved by technology
[0003] The purpose of the present invention is to overcome the defect that the dam surface cannot be parallel to the river bed after the movable slab of the traditional movable dam is laid down, and provides a concentric shaft for concentric rotation at the bottom of the movable dam. The concentric shaft has a simple structure; The plate is fixedly connected with the concentric shaft, which can realize the swing in the range of 0-180°, and can conveniently realize the single-sided and double-sided water blocking of the movable dam

Embodiment Construction
[0015] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0016] During specific implementation, combined with Figure 1-2 , a concentric shaft for a movable plate, comprising a steel pipe 1, the steel pipe is a circular seamless steel pipe. There is a row of eyelets on the horizontal tangent line of the steel pipe, and one end of the steel pipe 4 is vertically inserted into the eyehole and extends to the inside of the steel pipe. Concrete poured inside. Pouring concrete can remove the water in the steel pipe, prevent the steel pipe from rusting, and enhance the rigidity of the concentric shaft. The other end of the vertical threaded steel is connected with the steel mesh on the plate surface of the movable plate 5, and forms an integral body.
[0017] The two ends of the concentric shaft are equipp...

The invention discloses a concentric shaft for an active plate. The concentric shaft comprises a steel tube, wherein the steel tube is of a round structure; meshes are formed in the horizontal tangent line of the steel tube; one end of each deformed steel bar is inserted into the meshes and extends into the steel tube, and the other ends of the deformed steel bars are connected to the active plate; the inside of the steel tube is inserted with horizontal reinforcing steel bars, and the steel tube is sealed by pouring concrete. The concentric shaft disclosed by the invention is simple in structure; by inserting the reinforcing steel bars and pouring concrete in the concentric shaft, the inside of the concentric shaft is prevented from rusting, and the rigid strength of the concentric shaft is enhanced as well; since the concentric shaft is fixedly connected to the active plate, the active plate can significantly swing within a swinging range of 0-180 degrees, so that the active plate can be parallel with riverbed to realize the single-side and double-side water retaining of a movable dam; the concentric shaft is designed in a round shape and is pressed on watertight rubber on one point, so that water retaining and flood discharging effects are effectively improved.
Description
technical field [0001] The invention relates to the technical field of movable dam design, in particular to a concentric shaft for movable slabs. Background technique [0002] The movable dam is a revolutionary achievement of water conservancy science and technology. It is currently the world's leading movable dam technology. It is widely used in agricultural irrigation, fishery, ship locks, seawater tidal protection, small river management, small hydropower station construction, urban water system landscape and tourist attractions. Conceptual engineering. The movable dam is a new type of water storage and overflow device, which has a significant effect on water storage and overflow. The movable slab is an integral part of the movable dam, which plays the role of water retention and flood discharge. The movable plate of the movable dam can be a curved plate or a flat plate. The movable plate is generally fixed on the embedded parts through hinges, and the embedded parts a...
