A gate device that is easy to control the water level and keep the water flowing in the river

Abstract

The invention discloses a gate device which is convenient for regulating the water level and keeping the river flow unimpeded, which comprises a frame, a plurality of gate blades with the same structure, a matching first gear and a driving assembly for driving the first gear to rotate; The frame is installed in the river channel perpendicular to the water flow direction of the river channel, and the gate blades are evenly arranged on the frame perpendicular to the water flow direction of the river channel. The first gear is used to control the opening of the gate blades, and the first gear is installed on the gate blade side. In the present invention, the drive assembly is used to drive the first gear and drive the rotation of the gate blades to control the rotation of the gate blades to a certain opening, so that the water flows out along the bottom-up gap formed between adjacent gate blades. At the same time of raising, it can avoid the problem of no flow velocity at the bottom of the water flow, and ensure that the water flow flows smoothly through the entire section, thereby reducing the impact on the upstream flow velocity of the water flow.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and relates to a gate used in hydraulic physics model tests for adjusting and controlling the water level, in particular to a gate device which is convenient for regulating the water level and maintaining the unimpeded flow of the river. Background technique [0002] With the continuous development of hydraulic resources in today's society, more and more hydraulic structures have been built. For most of the hydraulic structures with rectangular cross-sections, such as fishways, rectangular channels, etc., before the construction of hydraulic structures, certain hydraulic analysis needs to be carried out to discuss whether their structures meet the requirements. Generally, hydraulic physical models are used to simulate hydraulic structures to obtain relevant hydraulic analysis results. [0003] The hydraulic physical model refers to a hydraulic model that reduces the origina...

Problems solved by technology

In this way, the bottom flow state of the part of the water flow in front of the water retaining device will often change greatly or even be zero, which will inevitably affect the measurement results of the water flow velocity in the model, and then affect the hydraulic analysis of the physical model, and even affect the completed project.
