Problems solved by technology

Therefore, it takes a lot of manpower and material resources to carry out the test of each slope in the traditional open channel curved water tank, and the repeated adjustment of the slope will cause great damage to the side wall glass
In addition, the fixed concrete floor also makes it impossible to use measuring instruments such as particle image velocimetry technology (PIV) to project a light source or take pictures from the lower part of the tank to measure the flow characteristics of the open channel bend water flow

Abstract

The invention relates to an open channel bend flume testing device, belonging to the technical field of water conservancy tests. The open channel bend flume testing device comprises a lifting system, a main beam, a support frame and a open channel bend flume consisting of a glass bottom plate and a glass side wall, wherein the open channel bend flume is installed on the support frame, the supportframe is welded on the main beam, and the lifting system supports the bottom surface of the main beam and is used for continuously regulating the slope of the flume. The open channel bend flume testing device has the advantages that the accuracy is high, the application range is wide, the adaptability is strong, the slope can be continuously regulated, and the manpower and material resources are greatly saved. The open channel bend flume testing device has important production practical value and popularization and application prospect.

Description

technical field [0001] The invention belongs to the technical field of water conservancy tests, and in particular relates to a test device for an open channel curved water tank and a manufacturing method thereof. Background technique [0002] Bends are common in natural alluvial rivers. Compared with the straight river section, the water flow characteristics and sediment transport law of the curved river section are very different, so special research must be carried out. The research methods mainly include field observation and indoor experiment. Due to the difficulty of field observation, long period and complex influencing factors, it is difficult to conduct systematic research. The indoor test generally adopts the open channel curved water tank test device consisting of the upstream inlet straight section 1, the midstream curved section 2, and the downstream outlet straight section 3. figure 1 It is a schematic plan view of a typical open channel curved water tank. Thi...
