Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of closure gates for water conservancy projects, in particular to a steel dam gate for ecological water storage. Background Art
[0002] The steel dam gate is a bottom-shaft-driven flap gate consisting of a civil structure, a steel gate body with a fixed shaft, and opening and closing equipment. The steel dam gate is suitable for conditions with wide gate openings (10-100 meters) and relatively small water level differences (1-7 meters). Because it can be designed to be relatively wide, it can eliminate the need for several gate piers. This simplifies the structure and saves considerable civil engineering investment. Furthermore, the gate can be used to store water vertically and drain water horizontally. It can be opened appropriately to adjust the water level, and the gate can be used to pass water over the top of the gate, creating the scenic effect of an artificial waterfall.
[0003] The existing steel dam gate shaft is prone to freezing when the temperature is low, which makes it difficult to open and close smoothly, affecting its use effect. Moreover, when the gate plate is opened, it is impacted by the water flow and its stability is affected. Relying solely on the self-locking of the shaft can easily cause damage to the self-locking structure. Utility Model Content

A driving motor is provided in one of the operating wells, and the driving motor is connected to the hollow rotating shaft. A heating power supply is provided in the other operating well, and a heating belt is provided in the hollow rotating shaft, and the heating belt is connected to the heating power supply. A plurality of support and limit assemblies are provided on the rear side of the gate assembly in the rotation direction.
[0007] The gate assembly is composed of several blocks, each of which includes an assembly cylinder at the bottom. A positioning key is provided on the inner wall of the assembly cylinder, and a matching key groove is provided on the outer wall of the hollow shaft. The assembly cylinder is passed through the hollow shaft and the positioning key is installed in the matching key groove. An arc-shaped gate is provided on the outer wall of the assembly cylinder.
[0008] The support and limiting assembly includes a base and a support rod, and the base is fixed to the ground foundation by bolts.
[0009] There is a closed manhole cover on the top of the operating well.
[0010] The beneficial effects of the present invention are as follows: by arranging a heating tape in the hollow rotating shaft, the heating tape can be used for heating when the temperature is relatively low, thereby avoiding the freezing of the outside of the hollow rotating shaft and causing the consequence of poor opening and closing rotation; the support and limit assembly can support the gate assembly, making it more stable when impacted by water flow, which is beneficial to protecting the gate assembly and extending its service life. The opening angle of the gate assembly can also be controlled, and a suitable support and limit assembly can be selected according to needs. BRIEF DESCRIPTION OF THE DRAWINGS
