Abstract

The invention discloses a concealed radial gate and belongs to the technical field of irradiation. The concealed radial gate comprises an arc-shaped flashboard, a drive assembly and a rotation assembly. The arc-shaped flashboard comprises an arc-shaped surface, a plane and two end faces at the two ends of the arc-shaped surface, wherein the arc-shaped surface, the plane and the end faces are matched for forming a sealed cavity inside the arc-shaped flashboard. A flashboard groove is formed in the bottom of a ditch. The rotation assembly is arranged inside the sealed cavity. In the non-work state, the arc-shaped surface of the arc-shaped flashboard is located in the flashboard groove, and the plane is located on the same horizontal surface as the bottom of the ditch; in the work state, under the effect of the drive assembly, the arc-shaped flashboard can rotate within the range of 0-90 degrees in the flashboard groove through the rotation assembly, the arc-shaped surface and the plane of the arc-shaped flashboard are partially located in the flashboard groove, and the part, located outside the flashboard groove, of the arc-shaped surface is used for retaining water. According to the concealed radial gate, the height of a gate weir crest is adjustable, and the energy is saved.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to a hidden arc gate. Background technique [0002] In the process of canal irrigation, gates are usually used to discharge water in the form of weir flow or hole flow. When releasing water, for irrigation water diversions, it is not only expected that the water level of the upstream water from the main and branch canals should be kept as stable as possible. It is also desirable that the flow of downstream distribution water to the branch channel be as constant as possible. Based on the flow formulas of weir flow and pore flow, it can be known that when the flow rate of upstream water increases by 1 times, the water level in front of the weir only increases by 0.6 times, while the water level in front of the sluice needs to increase by 3 times. It can be seen that the weir flow has a good function of stabilizing the water level, while the hole flow has a good function of stabili...
